Received: 25 January 2012; in revised form: 28 February 2012 / Accepted: 28 February 2012 / Published: 8 March 2012 Abstract: Improving fingerprint matching algorithms is an active and important research area in fingerprint recognition. Algorithms based on minutia triplets, an important matcher family, present some drawbacks that impact their accuracy, such as dependency to the order of minutiae in the feature, insensitivity to the reflection of minutiae triplets, and insensitivity to the directions of the minutiae relative to the sides of the triangle. To alleviate these drawbacks, we introduce in this paper a novel fingerprint matching algorithm, named M3gl. This algorithm contains three components: a new feature representation containing clockwise-arranged minutiae without a central minutia, a new similarity measure that shifts the triplets to find the best minutiae correspondence, and a global matching procedure that selects the alignment by maximizing the amount of global matching minutiae. To make M3gl faster, it includes some optimizations to discard non-matching minutia triplets without comparing the whole representation. In comparison with six verification algorithms,...

...Neural Networks for Matching in Computer Vision Giansalvo Cirrincione1 and Maurizio Cirrincione2 Department of Electrical Engineering, Lab. CREA University of Picardie-Jules Verne 33, rue Saint Leu, 80039 Amiens - France exin@u-picardie.fr Universite de Technologie de Belfort-Montbeliard (UTBM) Rue Thierry MIEG, Belfort Cedex 90010, France maurizio.cirricione@utbm.fr 1 2 Abstract. A very important problem in computer vision is the matching of features extracted from pairs of images. At this proposal, a new neural network, the Double Asynchronous Competitor (DAC) is presented. It exploits the self-organization for solving the matching as a pattern recognition problem. As a consequence, a set of attributes is required for each image feature. The network is able to find the variety of the input space. DAC exploits two intercoupled neural networks and outputs the matches together with the occlusion maps of the pair of frames taken in consideration. DAC can also solve other matching problems. 1 Introduction In computer vision, structure from motion (SFM) algorithms recover the motion and scene parameters by using a sequence of images (very often only a pair of images is needed). Several SFM techniques require the extraction of features (corners, lines and so on) from each frame. Then, it is necessary to find certain types of correspondences between images, i.e. to identify the image elements in different frames that correspond to the same element in the scene. This paper...

...Vijay V. Vazirani College of Computing Georgia Institute of Technology Copyright c 2001 Approximation Algorithms Springer Berlin Heidelberg NewYork Barcelona Hong Kong London Milan Paris Singapore Tokyo To my parents Preface Although this may seem a paradox, all exact science is dominated by the idea of approximation. Bertrand Russell (1872–1970) Most natural optimization problems, including those arising in important application areas, are NP-hard. Therefore, under the widely believed conjecture that P = NP, their exact solution is prohibitively time consuming. Charting the landscape of approximability of these problems, via polynomial time algorithms, therefore becomes a compelling subject of scientific inquiry in computer science and mathematics. This book presents the theory of approximation algorithms as it stands today. It is reasonable to expect the picture to change with time. The book is divided into three parts. In Part I we cover a combinatorial algorithms for a number of important problems, using a wide variety of algorithm design techniques. The latter may give Part I a non-cohesive appearance. However, this is to be expected – nature is very rich, and we cannot expect a few tricks to help solve the diverse collection of NP-hard problems. Indeed, in this part, we have purposely refrained from tightly categorizing algorithmic techniques so as not to trivialize matters. Instead, we have attempted to capture, as accurately as possible, the individual character...

...Accounting Theory Case Study 10.2 Accounting for frequent flyer points: fact or fiction ? Maylinda Irmayanti (023111146) Windy Ayu Wulandari (023111239) Case Study 10.2 Accounting for frequent flyer points: fact or fiction? Accounting requirements under IFRS have changed the way airlines account for frequent flyer points. In the past, the cost/provision approach accounting practices were used. Under this method, the upfront sale of points to bank, credit card companies, mortgage brokers, and general retailers was recorded as revenue in the income statement at the time of sale. The expense related to the sale, that is the cost of travel, was recorded at a later period, when the airline provided the travel service, or gave up the ‘free’ seat. The Australian Financial Review (AFR) reported in December 2004 that the sale of points to third parties, rather than giving them away to loyal customers, made the schemes profitable for Qantas and major network carriers in the United States and Europe. The newspaper claimed that when Qantas sought additional debt or equity capital, it would have to treat its frequent flyer point liability on the same basis as other global firm, in the name of equality and transparency. Qantas responded immediately to the AFR article. The company stated that it establishes a liability and takes a charge to the profit and loss account for the cost of providing a ‘free’ seat at the time the frequent flyer revenue...

...In the field of accounting, there has few general rules and guideline and defined as accounting principles. A number of basic accounting principles have been developed through common usage. And revenue recognition principle is one of the accounting principle and it is an important cornerstone of accrual accounting along with the matching principle. For the revenue recognition principle, the accounting guidelines demand that revenues is to be recorded on the company financial statement when the product delivery or service completion, without regard to the timing of cash flow. So, the company no need to wait until cash is received before they recognize revenue. For instance, a company made a sale for RM 10,000 within an accounting period but has not received payment. The sale is verified as revenue though the company was not paid. Revenue recognition principle also stated the revenue is to be recognized when the rewards and benefits associated with the goods sold or service provided is transferred, where the amount can be estimated dependability. For instance, no revenue is recognized when the talk time scratch card is sold by a telecommunication company but it is recognized when the buyer makes a call and consumes the talk time. Besides, the revenue recognition principle gives a guidelines to manager and auditors for the way to recognize the revenue. When the transaction is in its early stage, the outcome of transaction cannot be measured reliably because the transaction...

...users in confirming their past predictions may also be helpful in forming future forecasts. Reliability Concept: Information is reliable if a user can depend upon it to be materially accurate and if it faithfully represents the information that it purports to present. Significant misstatements or omissions in financial statements reduce the reliability of information contained in them. Matching Concept: Matching Principle requires that expenses incurred by an organization must be charged to the income statement in the accounting period in which the revenue, to which those expenses relate, is earned. Prior to the application of the matching principle, expenses were charged to the income statement in the accounting period in which they were paid irrespective of whether they relate to the revenue earned during that period. This resulted in non recognition of expenses incurred but not paid for during an accounting period (i.e. accrued expenses) and the charge to income statement of expenses paid in respect of future periods (i.e. prepaid expenses). Application of matching principle results in the deferral of prepaid expenses in order to match them with the revenue earned in future periods. Similarly, accrued expenses are charged in the income statement in which they are incurred to match them with the current period's revenue. Timeliness of Accounting Information Concept: Timeliness principle in accounting refers to the need for accounting information to be presented...

...S&H Green Stamps – Case Study Before we begin to discuss the timing of the revenue and expense recognition we should introduce a term related to loyalty programs which is called “breakage”. Breakage is the difference between points issued and points redeemed. Since S&H are getting cash for stamps issued to customers regardless of whether they are redeemed for goods later on (or not), the difference between the two is a major factor in their income and profitability. As we have learned, the realization principle is the concept that revenue can only be recognized once the underlying goods or services associated with the revenue have been delivered or rendered, respectively. Thus, revenue can only be recognized after it has been earned. In our case since we are discussing a loyalty program that has a “well-known” breakage percentage the revenues should be recognized at two different events. The first event (Event-I) takes place when the supermarket provides the stamps to the customer. At this point of time it is given that the supermarket will transfer a month later the funds related to this specific stamps transaction. Given that there is a well known “Breakage %”, we can claim at this point in time that S&H have already realized “Breakage %” of the revenues and as such we can recognize this “Breakage %” out of the expected funds transaction. The rest of the payment should be marked as a liability, till a customer attends one of the S&H stores in order to redeem goods for...

...Final Exam Review- Hitzig parts 1-3 1. Revenue Recognition: General: 25-1 The recognition of revenue and gains of an entity during a period involves consideration of the following two factors, with sometimes one and sometimes the other being the more important consideration: ← a. Being realized or realizable. Revenue and gains generally are not recognized until realized or realizable. Paragraph 83(a) of FASB Concepts Statement No. 5, Recognition and Measurement in Financial Statements of Business Enterprises , states that revenue and gains are realized when products (goods or services), merchandise, or other assets are exchanged for cash or claims to cash. That paragraph states that revenue and gains are realizable when related assets received or held are readily convertible to known amounts of cash or claims to cash. ← b. Being earned. Paragraph 83(b) of FASB Concepts Statement No. 5, Recognition and Measurement in Financial Statements of Business Enterprises , states that revenue is not recognized until earned. That paragraph states that an entity's revenue-earning activities involve delivering or producing goods, rendering services, or other activities that constitute its ongoing major or central operations, and revenues are considered to have been earned when the entity has substantially accomplished what it must do to be entitled to the benefits represented by the revenues. That paragraph states that gains commonly result from transactions and other events...

...------------------------------------------------- ------------------------------------------------- Microwave an RF Supplementary Project ------------------------------------------------- Equivalent Impedance of an Antenna Introduction: Antenna impedance is a measure of the resistance to an electrical signal in an antenna. Many factors have an impact on an antenna’s ability to transmit a signal, including the environment that the antenna is in and the design and composition of the antenna. Understanding antenna impedance is important when designing components that connect an antenna to a receiver or transmitter. The ratio to voltage current, which is equal to antenna impedance, is expressed in ohms. The antenna impedance represents the power that is absorbed by the antenna as well as the power that is dispersed by it as it comes into contact with electromagnetic waves. Voltage and Current Relationship: Antenna impedance relates the voltage to the current at the input to the antenna. Let us assume that the antenna has an impedance of 50 ohms. And if a sinusoidal voltage is applied at the antenna terminals with amplitude of 1 volt, then the current will have amplitude of I=VR=150=0.02 A. Since the impedance is a real number, the voltage is in phase with the current. Alternatively suppose the impedance is given by complex number say Z=50+j50 ohms. If Z=50+j50, then the impedance has the magnitude equal to: 502+502=70.71 The phase will be equal to: tan-1ImZReZ=45° ...
