Scheduling is an important process widely used in manufacturing, production, management, computer science, and so on. Appropriate scheduling not only reduces manufacturing costs but also reduces possibilities for violating due dates. Finding good schedules for given sets of jobs can thus help factory supervisors effectively control job flows and provide solutions for job sequencing. In simple f...
This paper presents a deadlock avoidance scheme that was developed during the Mascada Project—Esprit LTR Project 22728. The deadlock problem occurs in a car body painting shop. From this application, an abstract problem was derived for which a deadlock avoidance method was developed. The paper presents the deadlock avoidance scheme and its correctness proof. In addition, implementation issues a...
Two RPG Flow-graphs for Software Watermarking using Bitonic Sequences of Self-inverting Permutations
Software watermarking has received considerable attention and was adopted by the software development community as a technique to prevent or discourage software piracy and copyright infringement. A wide range of software watermarking techniques has been proposed among which the graph-based methods that encode watermarks as graph structures. Following up on our recently proposed methods for enco...
Scheduling is an important process widely used in manufacturing, production, management, computer science, and so on. Appropriate scheduling can reduce material handling costs and time. Finding good schedules for given sets of jobs can thus help factory supervisors effectively control job flows and provide solutions for job sequencing. In simple flow shop problems, each machine operation center...
This paper proposes a joint encryption and watermarking technique based on random block permutation and DWT with the motivation to enhance the security of the multimedia content. The original image is sectioned into the blocks and shuffle the blocks using random permutation, In this technique copyright information is concealed into an encrypted image. Based on the results, permutation of blocks...
This study is concerned with how the quality of perishable products can be improved by shortening the time interval between production and distribution. As special types of food such as dairy products decay fast, the integration of production and distribution scheduling (IPDS) is investigated. An integrated scheduling of both processes improves the performance and costs because the separated sc...
the increase of incomes in irans endowents (waqfs) could have an outstanding role in providing a part of public services needed in the society and betterment of income distribution and as a result endowers and benefactors would play a part in meeting greater portion of these services. materializing this objective requires an all-out development of endowment (waqt) services as wall as better ope...
