Exercise 1 1. Draw an E-R diagram for each of the following situations (if you believe that you need to make additional assumptions‚ clearly state them for each situation): a. A hospital has a large number of registered physicians. Attributes of PHYSICIAN include Physician_ID (the identifier) and Specialty. Patients are admitted to the hospital by physicians. Attributes of PATIENT include Patient__ID (the identifier) and Patient_Name. Any patient who is admitted must have exactly one admitting

BAR DIAGRAMS Bar diagrams are one of easiest and the most commonly used devices of presenting most of the business and economic data. These are satisfactory for categorical data or series. They consist a group of equidistant rectangles‚ one of each group or category of the data in which the values or the magnitudes are represented by the length or height of the rectangles‚ the width of the rectangles being arbitrary and immaterial. These diagrams are called one-dimensional because in such diagrams

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

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

Though we might not all have walked the exact same path‚ each person experiences an internal and physical journey. An internal journey is a reflective journey of the mind and spirit filled with uncertainty‚ challenges and conflicts. The growth we derive from such journeys can present us with an avenue for self-discovery and self-evaluation

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
