Research ArticleOpen accessIn the abstractResponse of Root Properties to Tripartite Symbiosis between Lucerne (Medicago sativa L.), Rhizobia and Mycorrhiza Under Dry Organic Farming ConditionsM. R. Ardakani, G. Pietsch, A. Moghaddam et al.Problem statement: It is generally considered that root turnover is a major contributor to organic matter and mineral nutrient cycles in organic managed agroecosystems. Approach: This study designed to investigate whether microbial activity could affect on root properties of Lucerne in an organically managed field under dry weather conditions. The trial was laid out as a factorial experiment in the … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 8,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccelerated Search for Gaussian Generator Based on Triple Prime IntegersBoris S. Verkhovsky, Md Shiblee SadikProblem statement: Modern cryptographic algorithms are based on complexity of two problems: Integer factorization of real integers and a Discrete Logarithm Problem (DLP). Approach: The latter problem is even more complicated in the domain of complex integers, where Public Key Cryptosystems (PKC) had an advantage over analogous encryption-decryption protocols in arithmetic of real integers modulo p: The former PKC have … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Test Scheduling and Test Access for ITC-02 SOC Benchmark CircuitsP. Sakthivel, R. Delhi Babu, P. NarayanasamyProblem statement: This study presented the optimized test scheduling and test access for ITC-02 SOC benchmark circuits using genetic algorithm. In the scheduling procedure of SOC, scheduling problem was formulated as a sequence of two problems and solved. Approach: Test access mechanism width was partitioned into two and three partitions and the applications of test vectors and test vector assignments … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,319 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Study of Fatigue Data Editing using the Short-Time Fourier Transform (STFT)S. Abdullah, C. K.E. Nizwan, M. Z. NuawiThis study presents the development of the STFT-based fatigue data editing technique that will be used as a tool to accelerate for accelerating fatigue testing. This technique was performed by removing low amplitude cycles contained in the original signal in order to produce a shortened signal using the Short-Time Fourier Transform (STFT) parameter. The effectiveness of STFT power spectrum was … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,430 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeuristic Algorithm in Optimal Discrete Structural DesignsAlongkorn Lamom, Thaksin Thepchatri, Wanchai RivepiboonThis study proposes a Heuristic Algorithm for Material Size Selection (HAMSS). It is developed to handle discrete structural optimization problems. The proposed algorithm (HAMSS), Simulated Annealing Algorithm (SA) and the conventional design algorithm obtained from a structural steel design software are studied with three selected examples. The HAMSS, in fact, is the adaptation from the traditional SA. Although the SA … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementation of Low-Memory Reference FFT on Digital Signal ProcessorYi-Pin Hsu, Shin-Yu LinProblem statement: In order to improve and implement Fast Fourier Transform (FFT), in general, an efficient parallel form in digital signal processor is necessary. The butterfly structure is an important role in FFT, because its symmetry form is suitable for hardware implementation. Although it can perform a symmetric structure, the performance will be reduced under the data-dependent flow characteristic. Even … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeo-Seismic Environmental Aspects Affecting Tailings Dams FailuresJuan M. Mayoral, Miguel P. RomoSeismic performance evaluations of tailings dams are essential for characterizing the geo-environmental risks posed by these earthen structures, which should include the geotechnical hazards implied by slope instability failure, free board loss and the potential release of contaminants. The observed damage is more important when liquefaction occurs on the dam body and foundation, which often leads to cracking, settlements, tilting … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Design Strategy for Volumetric Efficiency Improvement in a Multi-cylinder Stationary Diesel Engine and its Validity under Transient Engine OperationP. Seenikannan, V.M. Periasamy, P. NagarajThis paper proposes an approach to improve engine performance of volumetric efficiency of a multi cylinder diesel engine. A computer simulation model is used to compare volumetric efficiency with instantaneous values. A baseline engine model is first correlated with measured volumetric efficiency data to establish confidence in the engine model's predictions. A derivative of the baseline model with exhaust manifold, … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,502 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Permanent Deformation of Pavement's Unbounded Layers Based on Cyclic Triaxial TestsB. ŽlenderThis research presents an analytical model for determining permanent deformation of pavement's sub-grade and unbound granular base and sub-base material due to cyclic traffic loading. The model is given for interpreting results of repeated load triaxial tests. It considers long term elastoplastic behavior and resilient behavior of sub-grade and unbound granular material. Permanent deformations are expressed as a function of … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 7,127 accessesView PDFCite
Research ArticleOpen accessIn the abstractParallel Algorithms for String Matching Problem on Single and Two Dimensional Reconfigurable Pipelined Bus SystemsS. Viswanadha Raju, A. Vinaya BabuWe considered string matching on LARPBS and 2D LARPBS. This has applications such as string databases, cellular automata and computational biology. The main use of this method is to reduce the time spent on comparisons in string matching by using LARPBS. We investigated exact string matching and approximate string matching problems. For these two sub problems, we obtained O (n) … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,537 accessesView PDFCite
