Digital Logic Design

This course provides a modern introduction to logic design and the basic building blocks used in digital systems, in particular digital computers. It starts with a discussion of combinational logic: logic gates, minimization techniques, arithmetic circuits, and modern logic devices. The second part of the course deals with sequential circuits: flip-flops, synthesis of sequential circuits, and case studies, including counters, registers, and random-access memories. State machines will then be discussed and illustrated through case studies of more complex design systems. Different representations including truth table, logic gate, timing diagram, switch representation, and state diagram will...

An Enhanced PSO Algorithm for Scheduling Workflow Tasks in Cloud Computing

Abstract: This paper proposes an enhanced Particle Swarm Optimization (PSO) algorithm in order to deal with the issue that the time and cost of the PSO algorithm is quite high when scheduling workflow tasks in a cloud computing environment. To reduce particle dimensions and ensure initial particle quality, intensive tasks are combined when scheduling workflow tasks. Next, the particle initialization is optimized to ensure better initial particle quality and reduced search space. Then, a suitable self-adaptive function is integrated to determine the best direction of the particles. The experiments show that the proposed enhanced PSO algorithm has better convergence speed and better...

The Enabling Role of Information Technology in Software Engineering and Information Management Process: An Evolutionary Analysis

Abstract: Information Technology (IT) management is the practice of managing all IT resources in accordance with a company's strategic goals and demands. This comprises both real resources such as networking hardware, equipment, and personnel and intellectual properties such as software as well as data. IT has the ability to speed software development, quality, as well as effectiveness. The primary goal of IT management is to create value through the application of technology. To accomplish this, corporate objectives and technology should be in sync. Understanding the evolutionary procedures of information technology management is crucial to better comprehend how to handle IT nowadays. Many...
