National banking & delivery systems along with cultural & training challenges were evaluated too. Based on Iran governmental services constraints‚ we presented an appropriate architecture for large scale online shopping systems. Some of design phase diagrams are presented that could be useful for software developing companies. Index Terms—B2C‚ Electronic Commerce‚ Online Shopping System‚ SDLC Phases. I.

horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total of your system‚ a bullet that is moving at a certain speed and a block that is stationary: Initial

Types of Requirements : A. What is functional requirements ? A functional requirement defines a function of a system or its component. A function is described as a set of inputs‚ the behavior‚ and outputs . Functional requirements may be calculations‚ technical details‚ data manipulation and processing and other specific functionality that define what a system is supposed to accomplish. B. What is Non-functional requirements ? A non-functional requirement is a requirement that specifies

Advantages of Block Scheduling A small debate has always been discussed when talking about block scheduling and traditional class periods. Some people like the longer classes while others prefer the traditional six shorter class periods. Everyone has their own opinions about block scheduling. Block scheduling can be really helpful to high school students in many ways. Although‚ block scheduling is a longer time spent in one class‚ it should be mandatory in all high schools rather than traditional

126 (2001) MATHEMATICA BOHEMICA No. 1‚ 237–246 BLOCK DIAGONALIZATION J. J. Koliha‚ Melbourne (Received June 15‚ 1999) Abstract. We study block diagonalization of matrices induced by resolutions of the unit matrix into the sum of idempotent matrices. We show that the block diagonal matrices have disjoint spectra if and only if each idempotent matrix in the inducing resolution double commutes with the given matrix. Applications include a new characterization of an eigenprojection

FISHBONE DIAGRAM The cause-and-effect diagram was initially developed by Japanese quality expert Professor Kaoru Ishikawa. In fact‚ these diagrams are often called Ishikawa diagrams; they are also called fishbone charts for reasons that will become obvious when we look at an example. Cause-and-effect diagrams are usually constructed by a quality team. For example‚ the team might consist of service designers‚ production workers‚ inspectors‚ supervisors‚ quality engineers‚ managers‚ sales representatives

Building Blocks Retrospection David Nguyen National University Building Blocks Retrospection The building blocks questionnaire is a very thorough survey that is useful in deciphering a student ’s foundational‚ symbolic‚ and conceptual development. I personally would not recommend a teacher or adult to try to fill this form out without being fairly familiar with the student. This survey starts out broadly with seemingly broad questions‚ but gradually build up to more specific
