Entity-Relationship Diagrams (ERD) Data models are tools used in analysis to describe the data requirements and assumptions in the system from a top-down perspective. They also set the stage for the design of databases later on in the SDLC. There are three basic elements in ER models: Entities are the "things" about which we seek information. Attributes are the data we collect about the entities. Relationships provide the structure needed to draw information from multiple entities. Generally

CHAPTER 21 Accounting for Leases SOLUTIONS TO BRIEF EXERCISES BRIEF EXERCISE 21-1 The lease does not meet the transfer of ownership test‚ the bargain purchase test‚ or the economic life test [(5 years ÷ 8 years) < 75%]. However‚ it does pass the recovery of investment test. The present value of the minimum lease payments ($31‚000 X 4.16986 = $129‚266) is greater than 90% of the FV of the asset (90% X $138‚000 = $124‚200). Therefore‚ Callaway should classify the lease as a capital lease.

IEEE SIGNAL PROCESSING LETTERS‚ VOL. 21‚ NO. 7‚ JULY 2014 829 Discrete Anamorphic Transform for Image Compression Mohammad H. Asghari‚ Member‚ IEEE‚ and Bahram Jalali‚ Fellow‚ IEEE Abstract—To deal with the exponential increase of digital data‚ new compression technologies are needed for more efficient representation of information. We introduce a physics-based transform that enables image compression by increasing the spatial coherency. We also present the Stretched Modulation Distribution‚ a

Significant Figures in Measurement and Calculations A successful chemistry student habitually labels all numbers‚ because the unit is important. Also of great importance is the number itself. Any number used in a calculation should contain only figures that are considered reliable; otherwise‚ time and effort are wasted. Figures that are considered reliable are called significant figures . Chemical calculations involve numbers representing actual measurements. In a measurement‚ significant figures in
