Research ArticleOpen accessAll words, across the recordA Switching Mechanism Detection to Reduce Complexity in Multiuser Detection for DS-CDMA SystemsRekha Agarwal, B. V.R. Reddy, K. K. AggarwalWe present a reduced complexity switching mechanism which uses either matched filter or Parallel Interference Cancellation (PIC) detector based on channel characteristics. The main criterion of taking PIC detector is that it has less Bit Error Rate (BER) and less processing delay than other nonlinear multiuser detectors. This proposed detector reduces overall complexity while maintaining the same performance as PIC … …Journal of Mathematics and Statistics, Vol. 2, Issue 2 · 30 Jun 2007 · 6,641 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordConstraints Optimization for Minimizing Stretch in Bounded-ParameterizationAnuwat Dechvijankit, Hiroshi Nagahashi, Kota AokiIn a mesh parameterization process that generates one-to-one mapping information between a three-dimensional surface and a two-dimensional plane, we need to set some constraint positions in the solving system to define a specific location or size of the mapping plane. In this study, we will discuss how to perform a bounded-parameterization that minimizes distortion based on changing of constraints setting … …Journal of Computer Science, Vol. 12, Issue 9 · 26 Nov 2016 · 7,074 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordPresents Some Aspects and Applications of Projective GeometryRelly Victoria Virgil PetrescuProjective geometry is that area of geometry that treats geometric figures from the point of view of the perspective and the horizon line, figures that are considered invariable by projection. The origins are found in the Pappus works of Alexandria (4th century AD), which, referring to the results of Apollonius in Perga, introduces the concept of an anarchic report. The … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 10 Jul 2019 · 11,799 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDynamic Allocation of CPUs in Multicore Processor for Performance Improvement in Network Security ApplicationsSudhakar Gummadi, Radhakrishnan ShanmugasundaramProblem statement: Multicore and multithreaded CPUs have become the new approach for increase in the performance of the processor based systems. Numerous applications benefit from use of multiple cores. Increasing performance of the system by increasing the number of CPUs of the multicore processor for a given application warrants detailed experimentation. In this study, the results of the experimentation done … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,844 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordIncremental DataGrid Mining Algorithm for Mobility Prediction of Mobile UsersU. Sakthi, R.S. BhuvaneswaranProblem statement: Mobility prediction is the important issue in Personal Communication Systems (PCS). Mobile users moving logs are stored in data grid located in different locations. Distributed data mining algorithm is applied on this moving logs to generate the mobility pattern of mobile users. As new moving logs are added to the data grid, existing mobility pattern becomes invalid and … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 6,775 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDesign of a Merged DSP Microcontroller for Embedded Systems using Discrete Orthogonal TransformA. K. Rath, P. K. MeherIn this paper we have proposed the design of a DSP microcontroller where the processor load is significantly reduced by relegating the math-intensive DSP algorithm to dedicated transform computing modules. It is shown that the use of such transform modules will facilitate scalability, reusability and flexibility for implementation of wide varieties of DSP functionalities. Moreover, it would be possible to … …Journal of Computer Science, Vol. 2, Issue 5 · 31 Aug 2006 · 6,918 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Novel Reversible BCD Adder For Nanotechnology Based SystemsMajid Haghparast, Keivan NaviThis paper proposes two reversible logic gates, HNFG and HNG. The first gate HNFG can be used as two Feynman Gates. It is suitable for a single copy of two bits with no garbage outputs. It can be used as &#34Copying Circuit&#34 to increase fan-out because fan-out is not allowed in reversible circuits. The second gate HNG can implement all … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 10,135 accessesView PDF Cite
