Design Patterns **** CSS/422 **** **** Design Patterns The purpose of this paper is to compare and contrast five design patterns. An explanation of design patterns begins the paper. After the explanation are sections on Adapter‚ Facade‚ Factory Method‚ Observer‚ and Proxy. A conclusion completes the paper. Definition and Explanation According to SourceMaking (2010)‚ "In software engineering‚ a design pattern is a general repeatable solution to a commonly occurring problem in software

Design Pattern Matrix Design Patterns: From Analysis to Implementation by This is an excerpt from the manuals for Design Patterns Explained: A New Perspective for Object-Oriented Design Not all of the Gang of Four design patterns are included because not all of them are covered in the course. Furthermore‚ we use a variation on the classification of the GoF patterns: The Decorator and Proxy patterns are classified as Structural patterns by the GoF. Since they both add instead of just combining

looking at blood splatter‚ the forensic technician can conclude an estimated guess to the weapon used‚ the height of the person‚ whether it was foul play or not‚ and even if it was passive patterns or projected patterns. Blood splatter analysis becomes important when recreating a crime scene (Peschel). Bloodstain pattern analysis comes into play; and that is the interpretation of bloodstains at a crime scene in order to recreate the actions that caused the bloodshed (“A Simplified Guide”).

team’s understanding and innovative design abilities to solve all issues that arise from your development effort. Alternatively‚ you could make use of a design pattern that gives you a templateto follow towards designing a complete solution that solves different issues for different situations as they arise. That is the idea behind design patterns. They are not complete solutions themselves that can be magically turned into code. But‚ they can be used as templates for solving development problems by using

security. Architecture provides a set of abstract patterns guiding the design of a software system. This provides for problem-solving and planning to a software solution. Once the purpose and specifications of the proposed software is determined the next step is to design a plan for the solution. Design Patterns allows designers to reuse the fundamental concepts of methodologies employed from previous solutions to complete a current project. These patterns provide a template on how to solve a problem

Convergence is a point where the width and length on a plane from which the drops of blood stain was from. Area of Origin is an impact pattern of bloodstain where the height‚ width‚ and depth created. Both origin of impact pattern help investigator

Introduction: Bloodstain spatter pattern analysis is one of several specialities in forensic science. The analysis of the blood droplets upon contact with a surface is used to create a three dimensional space symbolizing the area of convergence of all the stains‚ this method is used to find the source of the blood. The source of the blood helps forensic analysts to understand the crime scene better and thus have an understanding of where the incident took place. A blood
