This paper proposes a novel distributed parallel EM modeling technique to speed up the process of neural network modeling for EM structures. Existing techniques for EM modeling usually need to repeatedly change the parameters of microwave devices and drive the EM simulator to obtain sufficient training and testing samples. As the complexity in EM modeling problem increases, traditional techniques...
We consider the problem of design tools of knowledge bases in the environment of the Semantic Web. The dynamics of the development of software tools and design architecture are considered in the context of software technology in Semantic Web. There is given also a short description of the software platform for operation of Knowledge bases as Projects of virtual reality in Semantic Web.
Data interoperability in scientific research is a major challenge. Heterogeneous data file formats, data structure formats, and data storage schemas are prevalent in the scientific research community. This poses a great challenge for collaboration between researchers due to data interoperability issues. In our prior work, we have addressed these challenges by proposing a web-enabled approach for generating...
There has always been a strong relationship between computer applications and computer architectures. Advances in computer architecture enable new usage models; new usage models challenge new architectures. For many decades, the interplays between applications and architectures have resulted in significant progress in the computer technologies. Recently, the computer industry adopts the multi/many-core...
The architecture described in this article belongs to a class of dynamic data flow architectures, in which the operand process control significantly affects the performance parameters as well as the system characteristics of the given architecture. The main component of the presented architecture is the multifunctional pipeline unit, which handles processing of data tokens representing the instructions...
This paper presents the question-answer approach to programming the designers activity during the collaborative development of software intensive systems. Such activity is aimed at the creative reuse of precedents in the real time when the human potential and power of computers are combined as a whole. The effectiveness of the common work can be increased essentially if the human part of the work...
This paper proposed a structured p2p model called balance-peer, introduce a method to partition the data rang without any global information on the load to. Our Balance-peer model is used to realize a partition-by-keyword indexing service based on DHT with each node in the system responsible for part of the keywords of the inverted index list. In this paper we use the concept of data partition in...
Performance evaluation techniques for fundamental graphics algorithms and for algorithms to be used in multimedia and embedded systems are investigated. Models of computation considering only arithmetic and logic operations taken on input data are regarded as inadequate for processors with instruction-level parallelism. For experimental evaluation of graphics algorithms clock-cycle counting is found...
Three dimensional memory systems has been argued as a potential pathway in solving the ever growing difference between comparative speeds of CPU and memory systems. In this paper, we describe a three-tier, three-dimensional SRAM macro that has been designed and fabricated in a 0.18 um FD-SOI CMOS technology. 3D stacking is found to improve wire latency as compared to planar memory structure although...
We present techniques for parallel divide-and-conquer, resulting in improved parallel algorithms for a number of problems. The problems for which we give improved algorithms include intersection detection, trapezoidal decomposition (hence, polygon triangulation), and planar point location (hence, Voronoi diagram construction). We also give efficient parallel algorithms for fractional cascading, 3-dimensional...
The time complexity of sorting n elements using p ≥ n processors on Valiant's parallel comparison tree model is considered. The following results are obtained. 1. We show that this time complexity is Θ(logn/log(1+p/n)). This complements the AKS sorting network in settling the wider problem of comparison sort of n elements by p processors, where the problem for p ≤ n was resolved. To prove the lower...
Some models of parallel computation consist of copies of a single finite automaton, connected together in a regular fashion. In such computers clerks can be a useful data structure, enabling one to simulate a more powerful computer for which optimal algorithms are easier to design. Clerks are used here to give optimal algorithms for the 3-dimensional connected is problem on a parallel processing array,...
The information processors in a decentralized computing system must trust each other enough to be mutually supportive, yet they must also protect themselves to maintain autonomy. In a decentralized system, data security is especially important because the effects of compromise or sabotage can be so wide-ranging. The trusted function is an ad hoc solution to a problem with present data security models...
