![]() ![]() ![]() Financial statements, including balance sheets, income statements, and cash flow statements compiled using GAAP, can represent the accurate economic picture of a company.ĥ. GAAP, introduced by the Financial Accounting Standards Board (FASB), provides standards applicable to every corporate organization to generate comparable, transparent, and fair information.Ĥ. GAAP is helpful for simplified reporting of a company’s financial information, providing better understandability and improved clarity for all the associated parties.ģ. There are various beneficiaries and users of the financial statements presented by a company other than the management itself, like shareholders and investors, governments or taxation departments, customers and suppliers, etc.Ģ. Anyone who make an invest on a company based on non-GAAP reports might as well be playing slots in Vegas.Need for Generally Accepted Accounting Principles (GAAP)ġ. For some insane reason non-GAAP reports are allowed alongside the GAAP compliant report, like to encourage investment by the clueless. Securities and Exchange Commission (SEC) in order to remain publicly listed on the stock exchanges. It has 10 general Principles:īecause of this GAAP compliant reports are required by the U.S. GAAP's goal is to improve the clarity, consistency, and comparability of the communication of financial information. In the U.S., Generally Accepted Accounting Principles (GAAP) is the common set of accounting principles, standards, and procedures issued by the Financial Accounting Standards Board (FASB). Yes they can make recommendations but those recommendations are dependent on what the owner wants. Furthermore how the business owner uses those reports is often outside of the accountant's control. Often accountants get the blame when a business does something for short term gains (laying a load of people off or raising a good's price for example) but in reality their reports are only as good as the information they are given. Things are so screwed up that what actually makes a profit and what doesn't is, many times, obscured to the point that no one really knows what the sam hill is going on.Īccounting's goal is to provide information which can be used to keeps a business profitable but in of itself it is a tool and like all tools it can be used or misused. One example of the type of insanity this produces is seen in Return of the Jedi the film cost $32.5 million and made $475 million at the box office.yet according to Lucasfilm the film "has never gone into profit" Harry Potter and the Order of the Phoenix, is even worse as it is claimed it has a lost of $167 million despite taking in $938 million in revenue. However, there is creative accounting beyond even what Enron and WorldCom did this little gem is known as Hollywood Accounting. ![]() Misrepresenting credit sales channel stuffing (sending a host of unordered goods at the end of the quarter and recording them as credit), recording nonrecurring expenses on a regular basis, and misuse of depreciation are all ways the books can be cooked. Enron and WorldCom have become poster children of what is informally called creative accounting, but other ways to cook the books aren't so obvious. Cooking the books is basically manipulation of accounting records toward making the records appear better then they actually are. Keeping two sets of books (one for internal use and one for the outside world) is the bottom of the barrel. These goals can conflict, however, when assets (such as real estate) actually appreciate in value over time, despite providing huge depreciation write-offs to their owners.Ĭooking the books is near the bottom of the barrel in accounting circles. The purpose of depreciation is twofold: it is meant to show assets' decline in value over time, and also to properly match the expense associated with the purchase of an asset to the revenue the asset helps produce over time. To oversimplify, depreciation represents the wear and tear of physical assets such as buildings or vehicles. Few things last forever - enter depreciation. ![]()

Nobody enjoys either a dead battery or a burned-up tool. Now you’ve created a potential “brick” pack that can no longer take a charge. What’s more-if a lithium-ion battery is “dumb” because the tool is smart, then putting it on a “dumb” tool means you can now drain the pack down below its nominal level. In both cases, all of the built-in protection that keeps both the tool and the battery from going so far that it damages itself is gone. Unfortunately, when you bypassed it with a battery adapter or voltage converter, you likely took away its ability to protect itself. Your car is most likely going to shut itself down before permanent damage occurs, and your cordless tool does the same. Just like the battery adapter, you’ve bypassed the electronic communications to do so. You’re just telling the tool to push the gas pedal farther. The same thing goes for these voltage boosters. See how long it takes for your temperature gauge to rise and idiot lights to illuminate. Tool battery adapters largely ignore the lines that govern safe use of a tool. Yes, we can push the tool and battery beyond what they’re rated for, but not for long and not without consequences. Just like the car, there’s an optimal operating range. This comes from extreme heat production in the motor and/or pack. Driving the motor beyond what it is designed to maintain will most likely result in failure. ![]() ![]() ![]() Anaglyph Maker v1.0 A very simple application to create anaglyph pictures.

Transmission describes sound energy passing through an obstacle, and the term transmission loss describes the proportion of that energy that is dissipated by the obstacle. Sound transmission is another relevant acoustic phenomenon that is modeled within Wwise Spatial Audio. Refer to Rooms and Portals' Diffraction to understand how Rooms and Portals lets you model portal diffraction, and to Using the Geometry API for Simulating Diffraction and Transmission to understand how geometry may be used to model diffraction of emitters and their early reflections. Wwise Spatial Audio models diffraction via two of its APIs. Also, the amplitude of higher frequencies decreases faster than that of lower frequencies, which means that it can be adequately modeled with a low-pass filter. ![]() We see that the edge can be considered as a point source, with amplitude decreasing with distance. This figure is just a coarse approximation in real life the field is continuous at the region boundaries, and edge diffraction occurs in the View Region as well, although it is generally negligible compared to the incident wave itself. The region on the lower right is the Shadow Region, where diffraction plays a significant role. The region on the top right is the Reflection Region, where reflection with the surface occurs and is mixed with the incident wave, resulting in this jagged pattern. The region on the left is the View Region, where the plane wave passes through unaltered. ![]() The perturbation caused by this edge is called diffraction. The following figure is a sound field plot of a plane wave coming from the top right and hitting a finite surface (the black line) that starts in the center of the figure. Diffraction is usually very important in games because it gives a hint to players about paths that exist between sound emitters and them. It represents sound that propagates through openings (portals) and towards the sides, meaning that a listener does not need to be directly in front of the opening to hear it. The following paragraphs provide a quick overview of the fundamental acoustic concepts related to Spatial Audio:ĭiffraction occurs when a sound wave strikes a small obstacle, or when it strikes the edge of a large obstacle or opening, and bends around it. ![]() |
