Rather than concentrating on general ad hoc networks and systems (GAHNS) that have to provide one-size-fits-all basis for all kinds of applications, this workshop proposes to focus on a variety of specialized ad hoc networks and systems (SAHNS), each suitable as a foundation for a restricted class of applications or even for an individual application. It is expected that SAHNS, thanks to exploiting...
A transaction is assigned with a purpose which is a collection of roles. Suppose a transaction T1 with a purpose R1 writes an object o2 after reading an object o1 and then another transaction T2 with R2 reads o2 and writes an object o3. Unless T2 is granted a read right of o1, illegal information flow occur from o1 to o2. In the purpose-marking(PM) protocol, T1 marks o2 with the purpose R1. T2 cannot...
This paper reports on a study in which developers' cognitive levels were categorised and measured while they mapped a sequence diagram to the related code based on a usage based reading scenario. Results indicate that applying the usage-based reading technique to map a sequence diagram to the underlying code, facilitates a developer to operate at the knowledge and comprehension levels of Bloom's cognitive...
In this paper, some existing inner bounds of multiple description problem are investigated. We prove that the El Gamal-Cover region is a subset of the Zhang-Berger (ZB) region. Furthermore, the Venkataramani-Kramer-Goyal region is equivalent to the Zhang-Berger region.
The InternationalWorkshop on Security in Systems and Networks is a forum for the presentation and discussion of approaches, research findings, and experiences in the area of privacy, integrity, and availability of resources in distributed systems. This workshop aims to bring together the technologies and researchers who share interest in the area of network and distributed system security. The main...
The past twenty years have seen a flurry of activity in the arena of parallel and distributed computing. In recent years, novel parallel and distributed computational models have been proposed in the literature, reflecting advances in new computational devices and environments such as optical interconnects, programmable logic arrays, networks of workstations, radio communications, mobile computing,...
In the development of software reverse engineering, program understanding is one of the most important steps. With the brief introductions of several program slicing technologies and their advantages and disadvantages, a new standard, used to choose slicing criterion, is proposed in this paper. By comparison with other methods, the experiment shows that the program slicing which is calculated by this...
In this study radial basis function neural network (RBFNN) was trained by different methods to study performance of each method on classification of ECG beats. To train the neural networks six types of beats including, normal beat (N), premature ventricular contraction (PVC), fusion of ventricular and normal beat (F), atrial premature beat (A), right bundle branch blok beat (R), and fusion of paced...
In this paper, the probability distributions of relative phase are studied. We proposed von Mises and wrapped Cauchy for the probability density function (pdf) of the relative phase in complex wavelet domain. The maximum-likelihood method is used to estimate the two parameters of von Mises and wrapped Cauchy. We demonstrate that the von Mises and wrapped Cauchy fit well with real data obtained from...
In this study; the optic disc determination and blood vessels extraction for hypertensive on fundus image are carried out. For the extraction of vessels edge detection methods such as Sobel and Kirsch are used and 2 dimensional multiscale gabor filters applied and their results are compared. These actions are applied to the right and left hypertensive fundus images which are taken from Gevher Nesibe...
Teaching opportunities for graduate assistants (TOGA) was initiated as a pilot program in 2005 by the School of Graduate Studies at Memorial university of Newfoundland becoming a pan-university program in 2007. Professional development for graduate teaching assistants related to teaching and learning is the primary focus of TOGA. TOGA within the faculty of engineering and applied science at Memorial...
The pervasive use of networks and the Internet has led the number of connected computing resources to grow tremendously, thus creating opportunity and need for heterogeneous computing systems. Furthermore, heterogeneity also is present in emerging computer architectures. In this context, issues of interest to HCW include but are not limited to: parallel and distributed computing programming paradigms...
We introduce a simple and flexible method to price derivative securities on assets with volatilities which are stochastic. As a special case we treat the SABR model in more detail. Our approach is based on the construction of recombining trees using interpolation methods on probability measures, and this makes it very suitable for the application of parallel computing techniques. We show how one can...
Welcome to the 10th IEEE International Workshop on Parallel and Distributed Scientific and Engineering Computing (PDSEC-09), held on 29 May 2009 in Rome, Italy, in conjunction with the 23rd IEEE Int. Parallel and Distributed Processing Symposium (IPDPS 2009).
Metal spinning is a plastic forming process in which a relatively ductile metal sheet is forced onto a rotataing mandrel by using a roller tool. This study is aimed at developing a versatile and intelligent forming process and expand the application area of robotic manufacturing processes. In this research, the metal spinning process has been accomplished with an industrial robot. Trajectory control...
