Research ArticleOpen accessIn the abstractQuality Metric Development Framework (qMDF)K. Mustafa, R. A. KhanSeveral object-oriented metrics have been developed and used in conjunction with the quality models to predict the overall quality of software. However, it may not be enough to propose metrics. The fundamental question may be of their validity, utility and reliability. It may be much significant to be sure that these metrics are really useful and for that their construct … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 7,383 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Prediction Model for Milling 618 Stainless Steel Using Response Surface MethodologyK. Kadirgama, K. A. Abou-El-HosseinThis study discussed the development of the first and second order power prediction model for milling 618 stainless steel with coated carbides cutting tool. The first and second order model has been developed by using response surface methodology with 4 factors. The surface methodology has been analysis by using statistical software Minitab. From the model the equation that relates the … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 7,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Data Base Scheme Arabic Handwriting Recognition by Hopfield Neural Networks AlgorithmHasan M. Al Shalabi, Mowafak F. Hasan, Abbas M. AliA new scheme for Arabic handwriting recognition by means of mat lab software is proposed. It can be seen as construction of neural networks that associate the hand writing Arabic text with the stored Arabic text in a specific data base are nearly equivalent. This result indicates that the new scheme have the potential to be robust in the presence … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,792 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of RNA-DNA Duplex Base Triplets to Antisense DrugsJie Yang, Yao Leng, Ju BaoSixty-four sets of three-dimensional models of RNA-DNA duplex base triplets were constructed based on codons by homology modeling method using software InsightII on Indigo workstation, which should be helpful for the study of RNA-DNA annealing, the basis of nucleic acids interactions and some peculiar motifs for design antisense oligonucleotides. Our research result reveal that the energies (such as E, Ec, … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Geo-Information Technology in the Study of Soil and Nutrients Loss by Water Erosion for three Different Land CoverMushtak T. Jabbar, C. A.I. Chong-Fa, Wang Tian-Wei, Shi Zhi-HuaThis research integrated the Revised Universal Soil Loss Equation (RUSLE) and the soil statistical analysis with RS and GIS techniques to quantify soil and nutrient loss risk. The Letianxi watershed, located in the southwest part of Hubei Province of China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,792 accessesView PDFCite
Research ArticleOpen accessIn the abstractWind Speed Simulation Using WaveletsA. H. Siddiqi, S. Khan, S. RehmanMost of the renewable energy sources have direct or indirect link with the sun. Wind is also a form of solar energy. It is initiated by uneven heating of the atmospheric air by the sun, affected from the topography and surface roughness of the earth's surface and rotation of the earth. The earth's terrain, water surfaces and vegetation cover modifies … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractSoil Degradation Risk Prediction Integrating RUSLE with Geo-information Techniques, the Case of Northern Shaanxi Province in ChinaMushtak T. Jabbar, Xiaoling ChenThis research integrated the Revised Universal Soil Loss Equation (RUSLE) with RS, GIS and GPS techniques to quantify soil erosion risk and the northern part of Shaanxi province in China was taken as a case. A system was established for rating soil erodibility, slope length/gradient, rainfall erosivity and conservation practices. The rating values served as inputs into a modified Revised … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,052 accessesView PDFCite
Research ArticleOpen accessIn the abstractDuration Modeling in Undergraduate Econometrics Curriculum via ExcelIsmail H. GencThe main goal of an Econometrics course is to prepare students for more advanced levels of study and make them able to cope with the empirical problems they are likely to face. In recent years, there has been a tendency to purge merely theoretical topics from the econometric textbooks by including only time honored methods. Survival analysis, however, has so … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvanced Multivariate Time Series Forecasting ModelsMiss Lei WangIn this study, the focus is to collect and summarize various advanced forecasting models for multivariate time series dataset. We have discussed about the inherent forecasting strengths and weaknesses related to these time series modelings. Also, the main section deal with the experience of using such data in econometric analysis. Besides, the implementation of SAS and R softwares improve the … …Journal of Mathematics and Statistics, Vol. 14, Issue 1 · 21 Dec 2018 · 7,323 accessesView PDFCite
