Book excerpt: The Shortest Job First algorithm gives the optimal average turnaround time for a set of processes, but it suffers from starvation for long processes. Starvation occurs when a long process is denied processor resources because the resources are occupied by short processes, thus, causing the long process to potentially never finish its task. This thesis considers that the short processes are soft real time processes. It presents the designer with a choice to select an algorithm that provides close to optimal average turnaround time within the soft deadline for short processes as compared to the Shortest Job First algorithm which results in decreased average turnaround time for long processes. The proposed algorithm improves drawback, related to long job starvation, in Preemptive-Shortest Job First by providing protection to a process through prioritization. A priority is assigned to a process based on a percentage of its burst time to completion, by introducing the parameter Theta, or the time spent by the process in the waiting queue, by introducing the parameter Lambda. Theta protects a current running process from being preempted when its execution time reaches a percentage of its total computing time. Lambda gives priority to a process when it exceeds a certain amount of time in the waiting queue. Four variants of the proposed scheduling methodology, each using a different theta and lambda, have been developed. The performances of these variants are compared against Highest Response Ratio Next (HRRN), Railroad, Enhanced Shortest Job First (ESJF), and Alpha scheduling algorithms that have been previously proposed. Experimental results show that our proposed algorithm performs better in terms of reducing the average turnaround time of the long processes while maintaining the turnaround time on the short processes at low desired levels, as those required for soft real time tasks.

This book was released on 2023-04-13 with total page 895 pages. Available in PDF, EPUB and Kindle. Book excerpt: Essentials of Computer Organization and Architecture focuses on the function and design of the various components necessary to process information digitally. This title presents computing systems as a series of layers, taking a bottom–up approach by starting with low-level hardware and progressing to higher-level software. Its focus on real-world examples and practical applications encourages students to develop a “big-picture” understanding of how essential organization and architecture concepts are applied in the computing world. In addition to direct correlation with the ACM/IEEE guidelines for computer organization and architecture, the text exposes readers to the inner workings of a modern digital computer through an integrated presentation of fundamental concepts and principles.

Book excerpt: Equity in the City is a collection of nine studies of the way the results of public investment in urban services are shared out among city-dwellers. The essays describe the way services such as water supply, electricity, roads and parks are financed and they analyse the way certain residents receive benefits from the public purse while others don't. It examines the impact on planning and zoning and building regulation in terms of who gains the benefits from government. Equity and the city reveals scarce public resources are allocated. This book was first published in 1981
Download or read book A Methodology Specification Language and Automated Support Environment for Computer aided Design Systems written by Duane Robert Worley and published by . This book was released on 1986 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Computer-based systems are becoming increasingly complex and expensive, and there is a need for extensive design prior to embarking upon costly implementation phases. Many design tools and design techniques have been proposed and some have been built to stand alone. They are, at best, loosely integrated with other tools. They have much in common, notably the construction and manipulation of models of the complex system under design and a high degree of interactivity. A detailed study of areas of commonality guides the requirements definition of a computer-aided design of computer systems (CADOCS) support nucleus. The nucleus provides an integrated set of primitives. A specification language targeted to the support nucleus allows description of the design model and human-model interaction. This paper hypothesizes that it is possible to define a methodology, a specification language, and an automated support environment suitable to the systematic development and execution of CADOCS systems. The methodology is applied to UCLA's Systems Architect's Apprentice (SARA) system--the test bed--and the resulting SARA/IDEAS system serves as an existence proof for the hypothesis."--Rand abstracts

Download or read book Fair Division and Collective Welfare written by Herve Moulin and published by MIT Press. This book was released on 2004-08-20 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of fair division is as old as civil society itself. Aristotle's "equal treatment of equals" was the first step toward a formal definition of distributive fairness. The concept of collective welfare, more than two centuries old, is a pillar of modern economic analysis. Reflecting fifty years of research, this book examines the contribution of modern microeconomic thinking to distributive justice. Taking the modern axiomatic approach, it compares normative arguments of distributive justice and their relation to efficiency and collective welfare. The book begins with the epistemological status of the axiomatic approach and the four classic principles of distributive justice: compensation, reward, exogenous rights, and fitness. It then presents the simple ideas of equal gains, equal losses, and proportional gains and losses. The book discusses three cardinal interpretations of collective welfare: Bentham's "utilitarian" proposal to maximize the sum of individual utilities, the Nash product, and the egalitarian leximin ordering. It also discusses the two main ordinal definitions of collective welfare: the majority relation and the Borda scoring method. The Shapley value is the single most important contribution of game theory to distributive justice. A formula to divide jointly produced costs or benefits fairly, it is especially useful when the pattern of externalities renders useless the simple ideas of equality and proportionality. The book ends with two versatile methods for dividing commodities efficiently and fairly when only ordinal preferences matter: competitive equilibrium with equal incomes and egalitarian equivalence. The book contains a wealth of empirical examples and exercises.
