The emergence of large-scale dynamic sets in real applications creates stringent requirements for approximate set representation structures: 1) the capacity of the set representation structures should support flexibly extending or reducing to cope with dynamically changing of set size; 2) the set representation structures should support reliable delete operation. Existing techniques for approximate...
Testing a software product is very much necessary to provide the customers with a quality product. The basic practices of testing involved are repetitive, expensive and wasteful. Along these lines, testing requires time to be adequately used, control the threats that one comes across and to keep a track of the quality metrics One should have the ability to beneficially recognize test circumstances...
Ensuring software security is essential for developing a reliable software. A software can suffer from security problems due to the weakness in code constructs during software development. Our goal is to relate software security with different code constructs so that developers can be aware very early of their coding weaknesses that might be related to a software vulnerability. In this study, we chose...
General Purpose Graphic Processing Unit(GPGPU) is used widely for achieving high performance or high throughput in parallel programming. This capability of GPGPUs is very famous in the new era and mostly used for scientific computing which requires more processing power than normal personal computers. Therefore, most of the programmers, researchers and industry use this new concept for their work...
This paper presents a compiler and runtime framework for parallelizing sparse matrix computations that have loop-carried dependences. Our approach automatically generates a runtime inspector to collect data dependence information and achieves wavefront parallelization of the computation, where iterations within a wavefront execute in parallel, and synchronization is required across wavefronts. A key...
In this paper, we proposed an innovative approachfor feature selection and model updating in big data machinelearning. Since hard drive access is the biggest barrier for bigdata problems, it is therefore nature to reduce disk I/O operationswhen evaluating different combinations of features, or updatinga learning machine. Particularly, we are interested in discoveringif small enough matrices exist...
This paper describes a new form of the wideband, wide scan notch array antenna which provides some distinct advantages. The Planar-Fed Folded Notch (PFFN) Array described herein differs from more traditional printed circuit board (PCB) and metal embodiments of the notch radiator array. PFFN array designs employ planar feeds that are incorporated on a single, common multi-layer PCB that is parallel...
Traditional distinction and recognition methods of electromagnetic radiation source have some shortcomings with highly error and long time. Therefore, Wilson algorithm, Lee algorithm and near field wave impedance theory have been proposed to analyze radiation source characteristics. And it presented common-mode radiation noise testing method of poor-average algorithm and differential mode noise testing...
This paper proposes an algorithmic approach and program for solving search problems statistically significant over the biological characteristics of genes in a given set. The problem is connected with the implementation of well known in biology permutation (randomization) test. By taking into account the potential parallelism permutation test developed in parallel with the implementation of a program...
The concept used in the research paper includes program slicing which is referred as the process of computing the chosen set of instructions of the program, The slicing criterion refers to the slice that is likely to affect the values at some point while executing the program. The paper highlights the different test cases and comparative analysis of program slicing methods which corresponds to the...
This paper covers the theory, measurement and analysis of a constructed reference system to capture and acoustically reconstruct a spatial soundfield for device testing. Using a rigid sphere microphone array, a framework is presented for numeric and visual representation of the multidimensional system performance. This is used to compare the measured acoustic spatial recreation of a practical 30 channel...
SIMD (Single Instruction Multiple Data) extension units are ubiquitous in modern processors. Array indirections raise several challenges for SIMD vectorization including disjoint memory access, unknown alignment and dependence cycle. Existing SIMD automatic vectorization methods fail to handle these challenges very well. This paper presents a new method exploiting Pure SLP (Superword Level Parallelism)...
One of the basic problem in computer science is to arrange the items in lexicographic order. Sorting is one of the major research topic. There are number of sorting algorithms. This paper presents the implementation and detailed analysis of library sort. Library sort is also called gapped insertion sort. It is a sorting algorithm that uses insertion sort with gaps. Time taken by insertion sort is...
Described in this paper is ongoing research in the development of methods to detect failures and anomalies within electronic components and printed circuit boards based upon observations of the interaction of energy applied to their physical materials and consequent radiated emissions that lie within the electromagnetic spectrum. These emissions are created using stimulus applied directly to power...
Modbat makes testing easier by providing a user-friendly modeling language to describe the behavior of systems, from such a model, test cases are generated and executed. Modbat's domain-specific language is based on Scala, its features include probabilistic and non-deterministic transitions, component models with inheritance, and exceptions. We demonstrate the versatility of Modbat by finding a confirmed...
In this paper, genetic data analysis using a hybrid supercomputer is considered. The architecture of a computer information system of search for traits of statistically significant overrepresented characteristics of genes from a given set is presented. The capabilities of one-level paralleling are demonstrated, and methods of modernization of the developed software are proposed. Modern technologies...
Advent of digital microfluidic embedded biochips has revolutionized accomplishment of laboratory procedures. Digital microfluidic biochips provide general-purpose assay execution along with several advantages compared with traditional benchtop chemistry procedures; advantages of these modern devices encompass automation, miniaturization and lower costs. However these embedded systems are vulnerable...
This paper studied how to quantify circular hole in steel with ultrasonic phased array technology. Ultrasonic pulses emitted from array elements will be reflected by defects, cracks or something else. The echo signals will carry the information of the reflector. When the reflector is a circular hole, two echoes will be received. From the two echoes we may obtain the size of the circular hole. We used...
This paper illustrates the design and implementation of a generic framework that can be used to enhance the capabilities of an existing automation test framework. This generic framework is used to support parsing test data, from files of all formats which are often used in the test execution phase. The paper distinguishes the test phase into a pre-execution, execution and validation, and post-execution...
The adaptive cross approximation algorithm is invoked for the fast construction of the method-of-moment matrix involving source basis functions for the currents and a set of auxiliary test functions that samples the radiated electromagnetic (EM) field. Once the adaptive cross approximation coupling matrix is constructed, the far and near fields from a source current are obtained directly through a...
