Window access control system: its design and implementation

Thesis Abstract

Introduction
In computer security, window access control (WAC) refers to a type of access control which the operating system (OS) constrains the ability of a subject or initiator to access or generally perform some sort of operation on an object or target.Expert system for human nutrition analysis is an expert system for diagnosing, controlling, and monitoring human nutrition. The system assesses the physical characteristics of the user to determine their nutritional status and makes recommendations for reaching nutritional requirements and a balanced diet, as a consequence generating a knowledge database with the nutritional status and dietary habits for the user. The system generates challenges, alerts, and constantly motivates the user to use the application and improve their nutritional habits. The expert system is implemented using the C++ Expert System Shell, libraries (Laboratories 2012) and the C++ programming language running as a Web Service on a Window Web Server. The system calculates the BMI, Body Mass Index,In one real world case at a chemical refinery a senior employee was about to retire and the company was concerned that the loss of his expertise in managing a fractionating tower would severely impact operations of the plant. A knowledge engineer was assigned to produce an expert system reproducing his expertise saving the company the loss of the valued knowledge asset. as in Eq. 1 (OMS 2012), the ideal weight and physical contexture, frame size (Rivas 1991) and uses dietary information from (Bermudez 2012). This is our base for nutritional diagnosis on the proposed system. This system will be developed for all users as a tool to improve their eating habits and nutritional wellbeing. The goal is to incorporate the use of this application into their daily lives and help them acquire and maintain healthier eating habits. In practice, a subject is usually a process or thread; objects are constructs such as files, directories, TCP/UDP ports, shared memory segments, input and output devices etc. Subjects and objects each have a set of security attributes.
