Transient Over Voltages Analysis In Power System Engineering Essay

Transient Over Voltages Analysis In Power System Engineering Essay Transient over-voltage is one of primary driver for unscheduled break in power transmission and appropriation frameworks including a keen matrix. A flood over-voltage because of lightning and exchanging activity brings about harms in an electrical force framework and regularly prompts power blackouts. Prescient computations of over-voltages created by the lightning and the exchanging activity in the transmission and dissemination frameworks are generally basic for a prudent protection structure and a dependable activity of the transmission and dispersion frameworks. The transient over-voltage can be high recurrence, medium recurrence or low recurrence. The transient over-voltage is risky to the two lines just as the associated hardware and may make harm the gear. This task investigates the transient at the heap subsequent to exchanging. This undertaking will examine about dissecting a transient over-voltages which is the reason and the impact of the transient over-voltages. The strat egy to illuminate this transient over-voltages likewise been talked about in this undertaking. The PSCAD recreation is utilized for the transient examination in this task to structure the force framework circuits. Issue Statement Voltage transient in Electric Power System seem a few unsettling influences, here and there risky for the electrical hardware life, for the earth and for the human life. Exchanging transient wonders produce in Power Systems over-voltages, over-flows and electrical fields, which havent to disregard. In this manner was displaying and reenacted the exchanging transient wonders, thusly the electric fields and the conceivable negative impact about electrical gear, condition and human life. Voltage transient in power framework are cause by exchanging activity, lightning and blames in the framework. The over-voltages can be hazardous to both the lines just as the associated gear and may make harm the hardware. Motivation behind this task is to break down the transient over-voltages at the heap and to recognize the technique to lessen the impact of transient over-voltages. 1.2 Project Objective The target of this venture is as per the following: Recognize the impact and the reason for transient over-voltages and furthermore the strategy to unraveling transient over-voltages. Mimic the transient over-voltages at the heap in the wake of exchanging and structure the force framework circuits by utilizing PSCAD reenactment. Investigate the outcome in the wake of exchanging and after use pre-addition resistor. 1.3 Project Scope So as to accomplish the goal of this task, there are a few extensions had been sketched out as follows: Examination on the dispersion framework. Creating the transient over-voltages waveform by utilizing PSCAD reenactment. The examination is simply centering into transient over-voltages that happen in light of the exchanging capacitor. Part 2 2.0 Literature Review 2.1 Introduction Voltage drifters in power frameworks are brought about by exchanging activities, lightning and blames in the framework. Various marvels make various sorts of homeless people. Oscillatory homeless people are caused for the most part by exchanging marvels in the system. The most widely recognized exchanging activity is capacitor bank exchanging. The most extreme homeless people are brought about by capacitor invigorating while capacitor de-empowering just motivations a minor transient. Oscillatory homeless people are portrayed by span, extent and phantom substance. There are subclasses of oscillatory homeless people contingent upon the prevailing recurrence. In this undertaking it will more concentrate on exchanging gadgets. 2.2 Power System Electric force framework is a significant piece of the foundation of present day society. The force framework today is mind boggling interconnected system. Electric force framework is the framework that can change and change the type of the vitality into electrical vitality and transmit it to buyer. Innovation today despite everything can't store the power that has been created. The electrical vitality possibly produce when required or it will use after it is created. As the impact, the administration on the power turns out to be hard and troublesome. The force framework might be partitioned into the four significant subsystems which are Generation subsystem, Transmission subsystem, Distribution subsystem and use subsystem. Figure 2.1 shows the force framework that isolated into age, transmission and conveyance. Figure 2.1: The Electric Power System 2.2.1 Generation Subsystem There are two significant parts in the age framework which is generators and transformers. For generators, a fundamental part of intensity frameworks is the three stage rotating current, air conditioning, generator known as simultaneous generator or alternator [1]. The wellspring of the mechanical force, usually known as the central player, might be water powered turbines, steam turbines whose vitality originates from the consuming of coal, gas and atomic fuel, gas turbines, or every so often inside ignition motors consuming oil [1]. Some substitute sources utilized are sun based force, geothermal force, wind power, flowing force and biomass. The force transformer move power with high effectiveness starting with one degree of voltage then onto the next level [1]. The transformer is been utilized to step up or step down the voltage. Protection necessities and other down to earth plan issues limit the created voltage to low esteem, generally 30 kV. The progression up is utilized for transmission of intensity. At the less than desirable finish of the transmission lines, step down transformers are utilized to lessen the voltage to appropriate qualities for dispersion or use. The power in an electric force framework may experience four or five changes among generator and purchasers [1]. 2.2.2 Transmission Subsystem An overhead transmission organize move electric force from producing units to the dissemination framework which at last supplies the heap. It likewise interconnects neighboring utilities which permit the monetary dispatch of intensity inside areas during typical conditions, and the exchange of intensity between locales during crises. The system that interconnected between the utilities and burden is called framework network [2]. The transmission line can be arranged into two classes which are high voltage transmission line and sub transmission line framework. The contrast between these two frameworks is in the voltage where for the high voltage, the level for transmission line voltage can arrive at 500kV and for sub transmission are in the middle of 69kV to 138kV. All the transmission will be ended at the substation [1]. 2.2.3 Distribution Subsystem The conveyance framework associates the dissemination substations to the purchasers administration entrance gear. The voltage for this sort of framework has been decreased by utilizing step down transformer from 66 kV to 22 kV and underneath. The auxiliary appropriation arrange lessens the voltages for usage by business and private customers. Lines and links not surpassing two or three hundred feet long at that point convey capacity to the individual customers. The optional conveyance serves a large portion of the clients at levels of 240 V for single stage and 415 V for three stages. Dispersion frameworks are both overhead and underground. The development of underground appropriation has been amazingly fast and as much as 70 percent of new private development is by means of underground frameworks [1]. 2.2.4 Utilization Subsystem The utilities framework or force framework loads are separated into three fundamental classifications which are mechanical, business and private. Mechanical burdens are composite burdens and enlistment engines structure a high extent of these heaps [1]. These composite burdens are elements of voltage and recurrence and structure a significant piece of the framework load [1]. Then again, business and private burdens comprise to a great extent of lighting, warming, cooling and cooking [1]. These heaps are free of recurrence and devour unimportantly little responsive force [1]. The heap changes for the duration of the day and force must be accessible to purchasers on request. The day by day load bend of an utility is a composite of interest made by different classes of clients. The best estimation of burden during 24 hour time span is known as the pinnacle or most extreme interest [1]. 2.3 Transient Over-voltages Transient is an abrupt increment in current or voltage in a circuit that can harm touchy parts and instruments. Transient overvoltages are a voltage top with a most extreme term of short of what one millisecond. It tends to be high, medium, or low recurrence. Transient overvoltages on power framework are because of different causes and can be grouped into two primary classifications, outer and inner overvoltages [3]. Common overvoltages on low voltage systems are brought about by direct lightning strikes. Lightning is an outer overvoltage. The elevated level of vitality contained in an immediate lightning strike on a lightning conductor or an overhead low voltage line prompts extensive harm of the establishment. The overvoltages can be more than multiple times the ostensible voltage. Working or exchanging overvoltages connected to a systems hardware make overvoltages of a lower level 3 to multiple times the ostensible voltage yet happen considerably more as often as possible, in this way causing untimely maturing of the gear. Exchanging overvoltages is an inward overvoltage. Transient overvoltages are commonly oscillatory and appear as a damped sinusoid. The recurrence of these overvoltages may fluctuate from a couple hundred Hz to a couple of kHz and it is represented by the intrinsic capacitances and inductances of the circuit. 2.2 Switching Capacitor Hardware containing electronic exchanging segments is likewise liable to create electrical aggravations practically identical to over-voltages. The results of which on touchy gear, yet not obvious, are no less impeding: untimely maturing and eccentric or short lived breakdowns. Working over-voltages are delivered when receptive or capacitive gear is turned here and there. Moreover, interfering with processing plant creation, lighting or transformers can

Did German Ambitions for World Power Make War Inevitable in 1914 free essay sample

The First World War was the greatest and bloodiest war to have been battled with present day innovation and caused wide spread turmoil and disaster that until that date was unrivaled in Europe. Of the 65,038,810 individuals prepared to battle from all the nations included 8,556,315 kicked the bucket, 21,219,452 troopers were harmed, and 7,750,945 were accounted for missing/P. O. W. Since the war was battled on such an enormous scope, and caused such wide spread catastrophe, all inside living memory, it makes it both a fascinating and disputable subject, and due to this there are a wide range of hypotheses about what the reason for WWI was. The most reprimanded party for the flare-up is Germany. There were a wide range of elements associated with the occasions prompting war, and Germany wound up at the foundation of most of them somehow. Indeed, even German history specialist F. Fischer was cited saying â€Å"Germany had a will to war† in his book Griff nach der Weltmacht (Germany’s points in the First World War) [1] Fischer’s hypothesis on the causes of WWI was that Weltpolitik was actuated on the grounds that Germany needed a war. We will compose a custom article test on Did German Ambitions for World Power Make War Inevitable in 1914? or on the other hand any comparative subject explicitly for you Don't WasteYour Time Recruit WRITER Just 13.90/page Anyway the effect of the occasions encompassing death of Franz Ferdinand must be considered, just as the different power’s activities/reactions. In 1890 after the excusal of Bismarck for Caprivi, Germany’s Weltpolitik started with three principle points; provincial extensions, production of financial ranges of authority, and development of the naval force. It very well may be contended that Germany realized that every one of these strategies would cause struggle with different forces, and that they were presented not just to make Germany an extraordinary force yet in addition to impel a war. In his first years in power Caprivi endeavored to unwind the mind boggling arrangement of collusions and responsibilities Bismarck had made during his long remain in office, and it tends to be said that his most significant choice as per Weltpolitik was his choice not to recharge the Reinsurance Treaty among Russia and Germany[2], anyway this was chiefly because of Holstein-a senior authority in the outside service who figured out how to utilize Caprivi’s absence of experience of remote issues to apply incredible impact over German strategy. By wanting to extend their naval force as a component of Weltpolitik Germany started a maritime pro with Britain. In 1898 came the primary German Fleet Act, after two years a second multiplied the quantity of boats to be worked, to nineteen ships and twentyâ€three cruisers in the following twenty years By expecting to have a greater naval force than different forces Germany planned to turn into an incredible force, and to have impact ov er the Balkans, and to have the option to increase a frontier empire[3]. It very well may be contended that, in light of the fact that as a feature of the maritime extension arrangement was to keep Britain in obscurity about it, Germany realized maritime development would incite the British and that it could prompt a battle between the forces. With their cryptic maritime race and the production of the Dreadnought, Britain turned out to be seriously incited and soon Germany and Britain were transformed into adversaries. Germany and England had recently been agreeable because of France being their common adversary, yet with the cryptic beginning of a maritime race with Britain Germany drove them away and towards another Britain, Russia and France union. This was assuredly a huge contributing element to the occasions prompting WWI, and guaranteed that Britain would not take Germany’s side-a factor that they were not well arranged for and would in the end lead to their loss of the war. Germany’s aspiration for overall extension, however, is seemingly the absolute most conspicuous occasion whose waves caused World War One. By 1890 practically the entirety of the pilgrim domains that were wealthy in trade merchandise and had a decent atmosphere, for example, Africa, were at that point split and part of the major power’s realms so when Germany concluded that she needed to extend her domain overall there was little land to be picked up, and the land that was accessible to be asserted was unwelcoming or poor thus Germany was confronted with the alternatives of taking area that nobody needed or to attempt to take the land from another nation. England had wished to have great relations with Germany, yet didn't need its options limited by mainland responsibilities, or, as Prime Minister Lord Salisbury put it:  Britain wished to dodge the â€Å"encumbering commitment of an alliance†. Relations with Britain improved, on account of the motions by Germany, for example, the Helgoland-Zanzibar Treaty of 1890[4], which killed provincial strains in East Africa and furnished Germany with a maritime base in the North Sea. Russia helped by the dread of an Anglo-German partnership, aligned itself with France in 1892, stopping many years of French seclusion, which had been one of the points and most prominent accomplishments of the Bismarck framework. Germany made insignificant increases, while a disillusioned France had now increased an incredible partner on Germany’s eastern flank, something which Bismarck had looked to maintain a strategic distance from for his whole time as chancellor. Had Germany not had any desire to cause struggle that could end in war then they would have attempted to pick up lands by political methods, buy or simply agreeing to land that was at this point unclaimed. Anyway Germany chose to attempt to take French and British terrains in Africa, estranging them from Germany as well as driving them together and shaping their political companionship and bolster that would later prompt the triple union. [5] During the Boer war Germany began to help the Boers and giving them the most recent rifles to battle the British with in an expectation that they would rather pick up the terrains and the gold and jewels to be found there by â€Å"diplomatic† implies after the British had been beaten. Their offer for the Boer lands was fruitless, and they drove the judgment of the Boer war, and the British’s utilization of death camps and the killing of detainees without preliminary amusingly some 40 after 50 years they would themselves utilize this strategy for a bigger scope are still sentenced right up 'til today for it. This drove Britain and France into establishing a collusion in 1904, and the Moroccan emergencies of 1905 and 1911 just served to drive them closer together for security against Germany’s hostility. Germany’s activities additionally made different powers amazingly antagonistic towards her, making mass clash. It was this forceful mentality combined with different nations dread and worry that made mass pressure all through Europe. Because of their forceful international strategy and expansionism plans, by 1912 Germany ended up encompassed by threatening nations. The Kaiser and driving military pioneers held a war bureau meeting to talk about â€Å"how to escape this mess†. It was concluded that as they were encircled by unfriendly nations that they would require a partner to help battle out. The choice to align with Austria as opposed to Russia is the thing that prompted the marking of the â€Å"Blank Cheque† of help for Austria[6]. It was likewise concluded that if a war happened that it would undoubtedly be in the Balkans, and that the sooner it happened the better supposing that Russia had additional time they could turn out to be too solid to even think about defeating, and as their partner Britain would be hauled into it in favor of Russia-something that Germany didn't need as they looked for Britain as partners. In spite of the fact that it very well may be said that Germany set the wheels of WWI moving, it tends to be contended that it was not at Kaiser Wilhelm’s heading alone, it was likewise because of Bismarck. Bismarck’s partnership frameworks had made competition and doubt between the forces, causing overall strain. The first of the significant unions to be framed was Germany with Austria-Hungary shaping the Duel Alliance to battle Russian impact in the Balkans, and in 1882 extended to incorporate Italy and turned into the Triple Alliance. Bismarck’s Franco-Prussian war of 1871 finished in France being vanquished by the Germans, and the development of a partnership framework to segregate France, and afterward Germany constrained France to pay Germany reparations. This collusion framework, albeit fleeting, permitted Germany to get more grounded and permitted her to feel that she could pull off a progressively forceful international strategy in the coming a very long time as there had been close to nothing/no intercession with their war with France[7]. In 1892 the Triple Entente, a collusion between France, Russia and Britain was shaped to check the power of the Triple Alliance and prompted increased strains as Germany wound up circled by unfriendly powers. A ton of accentuation is put on Germany’s inclusion in and activities paving the way to WWI anyway there are numerous other unmistakable contributing elements that can be said to have caused the war. One of these is the precariousness in the Balkans. After the decay of the Turkish Empire there was a â€Å"power vacuum† in the Balkans[8]. Both Russia and Austria needed to control the Balkans as were not solid in a union together, thus Germany decided to reestablish a collusion with the Austro-Hungarian Empire instead of Russia. Serbia a driven Slavic state won its freedom from the Turkish Empire aligned itself with Russia, and the Austrians assumed responsibility for Bosnia in 1908 making them nearly reach boiling point with Russia who had trusted that the â€Å"Black Hand† from Serbia would absorb Bosnia into Serbia. Austria thought back to the Duel union among themselves and Germany, who vowed to help them in the event that they battled with Russia. [9] After the death of the Arch-Duke Franz Ferdinand from Austria by an individual from the Black Hand the Balkans ended up split in two, with Serbia and Russia on one side, an

How to Spot Fraud Using Forensic Accounting

How to Spot Fraud Using Forensic Accounting Fraud is a serious problem companies need to prepare for.It can have a devastating effect on a business and damage the company’s reputation and workers’ morale aside from the obvious financial damage.So, what can companies do to detect fraud?In this guide, I’ll be outlining one popular way to spotting fraud: use of forensic accounting.What is forensic accounting and what is fraud all about?I’ll provide an overview of the concepts along with the techniques and processes used by forensic accounting to identify whether fraud has occurred.WHAT IS FORENSIC ACCOUNTING?Let’s break down the term forensic accounting first.According to Merriam-Webster, ‘forensic’ means, “relating to or dealing with the application of scientific knowledge to legal problems”.Therefore, when we combine it with the word ‘accounting’, we have a scientific study of accounting and any possible legal breaches within it.Essentially, the objective of forensic accounting is to analyze accounting pro cedures and findings and examine whether they are valid in the eyes of the law.You can, perhaps, understand the field better when you consider when forensic accounting takes place. Not all accounting is forensic â€" forensic accountants are called upon when there is a litigation happening or when litigation is expected to take place.Forensic accounting is most used to solve disputes and find answers â€" if things don’t add up in the accounting, for example.It is used, therefore, to investigate and analyze the financial activities of an entity and determine if there has been malpractice, either intentional or not.Forensic accounting is used to determine:How â€" The way in which the divergence has taken place.Where â€" At what point of the procedural chain has the divergence occurred.What â€" Is the divergence an intentional or not.Why â€" The motive or reason for the divergence, especially in terms of intentional divergence.Who â€" The person or other entity that is at fault.Now, f orensic accounting is useful for finding out whether fraud has taken place in the business.However, forensic accounting doesn’t just deal with fraud, but it can also be used in other non-fraud situations to determine the full picture of the financial matters.Whether forensic accounting finds fraud or is even supposed to look into possible fraud, the objective is to find and present evidence that could stand in front of the law.The process is aimed at finding evidence that can be presented in court in order to debate and dispute a resolution â€" for example, convict a company or a person for fraud.You can get more insight into forensic accounting by watching this short clip about a typical workday in the life of a forensic accountant: WHERE CAN FRAUD OCCUR?Fraud seems such a big word to use.To most of us, the word is something distant and the event of fraud is something that happens to others and not us.Since it seems such a drastic thing â€" fraud even sounds dramatic â€" it’s e asy to think it wouldn’t happen in your business.People in charge of small- or medium-sized businesses are especially shortsighted sometimes in terms of fraud.The truth is, fraud can happen anywhere. Small, big, new, old, international, local, brick-and-mortar, or online-only; your company could be faced with fraud and you should be aware of it, rather than hide from it.The nature of the fraud will depend on what your business does, as well as the kind of opportunities that are available to exploit.However, there are a few common areas of fraud.Fraud commonly takes place in situations of:Employees abusing their position. It could be a matter of hiding or changing information in order to benefit from the situation. For example, an employee might claim they’ve conducted work on things they haven’t actually worked on.Third-party suppliers or other business partners taking advantage of their position. The fraud can also be external â€" a supplier might lie about the number of prod ucts they are supplying, for example.Theft of confidential information that occurs either internally (someone in the organization stealing) or externally (an outsider steals information; an example could be hacking). Sensitive information can be stolen by an employee or an outsider and then used to damage the business.The above examples highlight the areas in which fraud often occurs.Since the avenues for the possibility of fraud are rather varied, it’s important that companies take it seriously.Creating business relationships that are built on trust is essential, but every company also needs proper checks and balances to limit the risk of fraud.Simply thinking it would never happen for your business is not solid protection against fraud.WHAT CONSTITUTES AS FRAUD?While fraud can happen in any kind of business, it’s important to also understand what actually constitutes as a fraud. Merriam-Webster defines fraud as:“intentional perversion of truth in order to induce another to p art with something of value or to surrender a legal right”“an act of deceiving or misrepresenting”From the above, two things point out in terms of what is fraud.First, the act must be conscious and intentional â€" unwittingly writing an extra zero in the income bracket is not fraud; if you do it intentionally, it is.The second point is about the act leading to a gain, which could be financial but it doesn’t have to be so.The act must provide some kind of benefit to the person or entity doing it or infringe on the legal rights of someone else.Now, the specific definition of fraud in the eyes of the law can vary from country to country. Nonetheless, those two points generally always appear in the legal definition in one form or another.With all of that in mind, three core elements can help you understand whether something is fraudulent or not. These are:The law of the land will determine whether the act constitutes as fraud. This is always determined on a case-by-case basis an d the available definitions and test cases will be set out by the regional or national court under which the business operations would fall into. Forensic accounting would always use this legal definition of fraud as the basis for determining whether there has been fraud or not.The auditor cannot determine what constitutes as fraud. The forensic accounting team is not to make judgments or determine if fraud has taken place â€" it’s role is only to investigate and present evidence to the court of law, which makes the ultimate decision.Fraud always requires intention. In all events, fraud cannot take place without intention and part of the forensic accounting team’s job is to find if there is enough evidence to show there has been an intentional effort to change, tweak or other how mishandle the information.WHEN CAN FORENSIC ACCOUNTING BE USED?With all that in mind, when can forensic accounting be used to spot a fraud?There are essentially two clear cases in which forensic account ing is the perfect tool for detecting fraud and presenting evidence that it might have happened.Forensic accounting can be used in situations where there is a possibility of fraudulent accounting and reporting. This would occur if a company suspects that an employee or a third-party supplier has been doing something illegal.The problem could be spotted by the accounting team within the company and reported to management.The possibility of fraud can also be something spotted by an outside â€" for example, during a random audit or when annual taxes are being checked by the authorities.Once a possibility of fraud has been established, the forensic accounting team is called in to investigate the situation.As noted above, the forensic accountant won’t make a judgment on whether the fraud took place, so at this point, legal teams are involved in determining what happens with the evidence presented by the forensic accountant.The other case for seeking help with a forensic account is when there has been a clear misappropriation of assets.Again, this can be something directly spotted by the internal teams â€" accounting or likewise â€" or it can be noted by external entities. These are situations where the assets have been taken but the forensic accountant’s job is to find evidence to suggest or support the event has been fraudulent.For example, the company might notice it is missing part of its income and the forensic accounting team will begin investigating whether there has been fraud or just another unintentional error in reporting.THE PROCESS OF USING FORENSIC ACCOUNTING TO SPOT FRAUDSo, forensic accounting can be used when there’s a suspicion or strong possibility of fraud.But what about the process?How does forensic accounting go about finding evidence to support either argument?Essentially, forensic accounting uses processes similar to a normal audit â€" it follows four specific steps in order to draw its conclusions.Planning the investigationFirst, the i nvestigation must be planned.Forensic accounting requires the use of forensic accountants, which have to be hired from outside of the firm to ensure partiality in the investigation.Once the investigators have been found and hired, the forensic accounting team can start preparing for the investigation.The team generally starts by laying out the objectives it wants to achieve. These are the how, what, where, when and why of the investigation, which I’ve already outlined above.Forensic accounting will look at each objective and identify the different ways these can be achieved and how evidence can best be identified and gathered.At this point, the team will create a schedule of operating and determine who is in charge of which part of the investigation (in case a bigger team is needed).Gathering evidenceThe second part of the investigation process is the most demanding and long-lasting.It is about gathering the evidence to disprove or prove the action of fraud.The focus at this point is on ensuring there is enough evidence for the courts to make a decision â€" the how, what, where, when and why are at the heart of this process, with each method and technique used to find information on these points.There are a number of techniques forensic accounting can use to gather evidence.The three most common techniques in terms of identifying fraud will be outlined in the next section.But to give you an idea on what happens during the process, here are a few evidence gathering things forensic accountants might use:Using testing controls to identify weaknesses in the system and noticing how and why the fraud could have taken place.Utilizing analytical procedures to compare trends in the data and making comparisons between different areas of the business to spot deviations.Interviewing employees and other key members that could have information regarding the fraud.Taking advantage of computer assisted auditing software to identify issues of timing and other relevant data i ssues.Opting for substantive techniques, which include things such as cash or asset counts.Reporting the findingsOnce the forensic accounting team has been able to gather all the evidence, they will need to report the findings.The report is often used for determining whether legal action shall be brought forward or if there is no evidence to suggest fraud has taken place.The main function of the report is to summarize the evidence and to provide a conclusion whether the deviation or loss of assets was due to fraud or not. You will also be able to read an answer to the core questions â€" how the fraud took place and when it is suspected to have happened, for example.The report is often also used for identifying possible recommendations for strengthening the accounting in the business and preventing future frauds.Dealing with possible court proceedingsThe fourth step in the process can technically be obsolete if the report doesn’t find any evidence to back up a claim of fraud.Howeve r, if fraud is still suspected, the forensic accounting has to be prepared to deal with the possible court proceedings.Team members will in most cases need to be part of those proceedings and they are often called to testify and explain the evidence to the jury and judge.The forensic accounting team has to be able to provide and present the evidence in a way that is accessible to the wider audience â€" the judge and the jury might not have specialist knowledge of accounting and thus the evidence must be laid out in layman’s terms.THREE FORENSIC ACCOUNTING TECHNIQUES TO DETECT FRAUDWhen it comes to detecting fraud, there are three forensic accounting techniques used. These are data mining with computers, review of other documents using various methods and conducting interviews.Data mining with computersData mining is about looking for anomalies, trends and patterns in the data relating to the business and its finances.These could include the digital accounting files available or fi les and datasets relating to products, suppliers and so on.As the world is increasingly moving from traditional paper filing to digital filing, data mining is becoming a more important tool for forensic accountants.The data mining is often done with automated software that has been designed to notice anomalies or patterns. Occasionally, a person reviews the data and the forensic accounting team studies any noticeable differences further.A big part of the data mining involves around the concept of Metadata. This is the information related to the organizations computer programs and the specific files used. Metadata is used to identify things like:The date when the file was created and whether it had been modified.The location of the file and whether it has changed.The identity of the person who has modified and changed information or the location.Finding and understanding the trail of the digital files is important because it can reveal fraud.For example, if the financial figures are wrong, data mining can identify whether they have been wrong since the start (i.e. possibly as a result of a typing mistake) or if they have been tampered with later (i.e. changed to create stronger income figures and thus pointing to a fraudulent and intentional action).Aside from the metadata, forensic accounting also uses data mining to review the information in the file and the patterns revealed by data.Forensic accountants can spot fraud by data mining with actions like:Evaluating the frequency of payments and consistency of financial figures.Finding gaps in ledgers or missing data files or information.Examining the vendor and supplier information, including addresses.Data mining also utilizes different mathematical formulas for spotting fraud. Among the most popular is the Benford’s Law. The technique is explained further in the video below: Data mining is performed on any computer or another device that is used by the organization and which could include information that mi ght help the forensic accounting team.These include things like personal computers, network servers, answering machines, digital cameras, fax machines, printers, GPS systems and so on.Reviewing other documentsOf course, information isn’t always in digital format and forensic accounting has to use document reviewing strategies to spot fraud. Reviewing physical documents can be tricky for the forensic team because they need to ensure they follow the right legal procedures in accessing, storing and managing these files.For example, they can’t illegally obtain business documents and then use them to accuse the business of fraud â€" everything has to follow the correct and legal route.Generally, when the forensic team receives an invitation to perform the investigation, a legal contract is formed that issues the forensic accounting team with the rights and responsibilities regarding the documents.In certain instances, the contract also has to deal with the proceedings for digital doc uments and any documents that might be accessed on employee premises.Interestingly, a big part of the document review is identifying the carbon copy of these documents. This means checking whether the documents have been modified after the date they are meant to have formed or simply added in later.Let’s say an employee would try to tamper with sales numbers, he or she might re-print the invoices with different figures.The review of other documents uses similar techniques to above in finding trends and patterns.Reviewing will be more laborious if it has to be done manually but forensic accounting teams often scan and create digital data files of the documents to allow data mining.Conducting interviewsBut forensic accounting doesn’t just have to rely on data. Talking to employees and other key parties is another crucial technique to help identify data.For example, by interviewing the organization and the supplier, different stories of the invoicing procedure might come up and poi nt to the system being fraudulent. Indeed, sometimes the fear of the investigation can make people talk and admit fraud â€" helping the forensic team to find the answers to the questions they might have.Again, it’s crucial to ensure the interviews are conducted professionally and within the legal boundaries of the country.The process must be coordinated with the legal teams and generally, there has to be some kind of record of the interview (this can be used in the court as evidence, rather than have a situation of ‘he said, she said’). The purpose of the interview is to identify the following things, which could point out a possibility of fraud:Knowledge of the information being examined.Opportunities to change, swap or manipulate data.Understanding of the procedures being used in the organization.The forensic accounting team has to be good at communicating with people and use a logical approach to getting to the bottom of things.It’s important to realize that you might not receive a pure admission of guilt â€" the person’s unusual behavior might be a sign there is something suspicious going on that needs to be investigated.CONCLUDING REMARKSFraud is not just something that occurs in big, popular companies. It can happen to small or big businesses in all industries.Detecting it can be difficult but forensic accounting provides quite a good number of solutions to identifying whether a fraudulent activity has taken place.It uses modern technology in the form of data mining to notice anomalies and patterns in data.But it also helps spot fraud by focusing on the people involved in the situation â€" using documents and interviews to see whether things are out of the ordinary.It is essentially picking the pieces apart and seeing whether putting them back together leads to the same results or if things are out of the ordinary.

A Brief Note On The Treaty Of Versailles - 1584 Words

After having to pay compensation for World War I due to the Treaty of Versailles, Germany was in shambles; people were unemployed, humiliated, and divided almost to the point of a civil war. They were in need of a strong leader to bring them together, and Adolf Hitler, with his powerful speaking skills and manipulative speeches, seemed to be the desirable candidate. His speeches and charisma, timing and strategy, and the fact that Germany was in disarray, allowed him to quickly rise through the ranks of the German Worker’s Party and seize the hearts and minds of his fellow Germans. The Treaty of Versailles, an important element leading to Hitler’s rise to power, divided Germany and provided the perfect conditions for a new ruler to take†¦show more content†¦Sure enough, the treaty sent Germany into an economic downward spiral and the government quickly went bankrupt. To fix this the German government tried to print more money, but hyperinflation followed, backf iring and making money practically useless. People, including Adolf Hitler, were left homeless, hungry, and desperate for any type of work. â€Å"There was never really an effort to deal with the damage done in World War I,† said Leon Panetta, the 23rd US Secretary of Defense, in the TV series, The World Wars, â€Å"failure to do that is what ultimately produce the seats for Hitler and Nazism.† The German people were dealing with the damage by themselves and had no one to help them. They were in dire need of a savior, and Adolf Hitler, a new member of the German Worker’s Party, would prove to be just the man they needed. He took advantage of the state Germany was in and used it to become a powerful figure. People wanted someone strong and stable to help them and needed a person or group of people to blame their problems on; Hitler offered both of these, himself and the Jewish. Taking advantage of the German people at their worst would be an important part of Hit ler’s rise to power; however, to do this Hitler would first need to make himself

Ancient Chinese Invented Gunpowder

Few substances in history have had as profound an effect on human history as gunpowder, yet its discovery in China was an accident. Contrary to myth, it was not simply used for fireworks but was put to military uses from its time of discovery. Eventually, this secret weapon leaked out to the rest of the medieval world. Chinese Alchemists Tinker With Saltpeter and Make Gunpowder Ancient alchemists in China spent centuries trying to discover an elixir of life that would render the user immortal. One important ingredient in many of the failed elixirs was saltpeter, also known as potassium nitrate. During the Tang Dynasty, around 850 A.D., an enterprising alchemist (whose name has been lost to history) mixed 75 parts saltpeter with 15 parts charcoal and 10 parts sulfur. This mixture had no discernable life-lengthening properties, but it did explode with a flash and a bang when exposed to an open flame. According to a text from that era, smoke and flames result, so that [the alchemists] hands and faces have been burnt, and even the whole house where they were working burned down. Use of Gunpowder in China Many western history books over the years have stated that the Chinese used this discovery only for fireworks, but that is not true. Song Dynasty military forces as early as 904 A.D. used gunpowder devices against their primary enemy, the Mongols. These weapons included flying fire (fei huo), an arrow with a burning tube of gunpowder attached to the shaft. Flying fire arrows were miniature rockets, which propelled themselves into enemy ranks and inspired terror among both men and horses. It must have seemed like fearsome magic to the first warriors who were confronted with the power of gunpowder. Other Song military applications of gunpowder included primitive hand grenades, poisonous gas shells, flamethrowers and landmines. The first artillery pieces were rocket tubes made from hollow bamboo shoots, but these were soon upgraded to cast metal. McGill University professor Robin Yates notes that the worlds first illustration of a cannon comes from Song China, in a painting from about 1127 A.D. This depiction was made a century and a half before Europeans began to manufacture artillery pieces. The Secret of Gunpowder Leaks Out of China By the mid- to late-eleventh century, the Song government had become concerned about gunpowder technology spreading to other countries. The sale of saltpeter to foreigners was banned in 1076. Nonetheless, knowledge of the miraculous substance was carried along the Silk Road to India, the Middle East, and Europe. In 1267, a European writer made reference to gunpowder, and by 1280 the first recipes for the explosive mixture were published in the west. Chinas secret was out. Down through the centuries, Chinese inventions have had a profound effect on human culture. Items like paper, the magnetic compass, and silk have diffused around the world. None of those inventions, however, have had quite the impact that gunpowder has, for good and for bad.

The sunsets in the distance falling slowly behind the vast spread of water and already high in the sky the moon begins it’s over watch. The beach, now cast in a reddish old light begins to cool off from the hot day and the sea, sparkling in the fading light rolls quietly in.

Interpersonal Communication for Feedback and Organizations

Question: Discuss about theInterpersonal Communication for Feedback and Organizations. Answer: Interpersonal communication has always existed for so long since human beings are social in nature and in one way or another they need to share information or feelings. The process through which people are able to exchange meaning, feelings or information is referred to as interpersonal communication (Beebe, Beebe Redmond, 2014). Personal communication is the face to face communication between an individual that occurs through either verbal or non-verbal modes. Interpersonal communication involves how the message is communicated through features such as body language, the tone of voice or gestures. Feedback is an important integral of interpersonal communication and effective feedback facilitate smooth flow of information. An effective feedback should be clearly heard, understood and accepted. To give effective feedback there are several guidelines and considerations to be observed. The feedback should be as specific as possible as this will make it easy for the other party to under stand it. The feedback should be timely and you should think about what you are going to say and how at the appropriate moment. While giving feedback one should concentrate on behavior and their effect and not on personality. The interpersonal skill of feedback is very important in a workplace since it promotes teamwork and effective communication within an organization (Amanda, 2013). Good interpersonal communication promotes good leadership since it promotes empathy and trust within members of staff. Effective feedback skills play a critical role in promoting credibility and customer satisfaction. Personal relationships are important in the workplace and this can be fostered and maintained by the existence of effective interpersonal communication mechanisms within an organization (De Janasz, 2014). In conclusion, interpersonal communication skills consist of how people communicate both verbally and non-verbally. Effective feedback skills have to follow certain guidelines that ensu re the feedback given is clearly understood and accepted.
