Research ArticleOpen accessIn the abstractLearning Dynamics in the Cobweb Model with Heterogeneous ProducersCarl Chiarella, Xue-Zhong HeIn this study we investigate the nonlinear dynamics of the traditional cobweb model with two types of heterogeneous producers who are risk averse and seek to learn the distribution of asset prices, in terms of the sample mean and variance of historical prices, using the Arithmetic Learning Processes (ALP) over different window lengths. We show that heterogeneity has a double … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 15 Dec 2005 · 7,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimation Techniques for Monitoring and Controlling the Performance of the Computer Communication NetworksIbrahiem M.M. El Emary, Adanan I. Al RabiaThis study was concerned with making a comparative study between four types of time series model with the goal of choosing the optimum one to predict the performance of a computer communication network. The investigated four types of time series are: Least Square (LS), Fourier series, Exponential Weighted Moving Average (EWMA) and the Auto Regressive Integrated Moving Average (ARIMA). Comparative … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,131 accessesView PDFCite
Research ArticleOpen accessIn the abstractForce Prediction Model for Milling 618 Stainless Steel Using Response Surface MethodologyK. Kadirgama, K A. Abou-El-HosseinThis paper describes the development of a response model (cutting force) for milling 618 stainless steel utilizing response surface methodology. The cutting force model is developed in terms of cutting speed, feed rate, axial depth and radial depth. The cutting force contours have been generated from these model equations and are shown of different plots. The model generated show that … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,700 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Comparison between Structural Element of Building Systems in MalaysiaM. R. Abdul Kadir, W. P. Lee, M. S. Jaafar et al.The Industrialized Building System (IBS) was introduced in Malaysia in 1966, but it failed to establish itself on a continuous basis though there has been a sustained large market for residential projects even since. One of the reasons behind this shortcoming is the lack of scientific data on labor productivity that could convince policy maker. Hence, the objective of this … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,070 accessesView PDFCite
Research ArticleOpen accessIn the abstractRetail Banking Loan Portfolio Equilibrium Mix : A Markov Chain Model AnalysisV. Thyagarajan, Saiful Maznan Bin MohamedThe variance analysis of actual loan sanctions with the non-documented method of loan allocation of the selected retail bank, over a period of 24 months, revealed that there is a scope to improve their income earnings. Realizing its importance Markov Chain Market Share model was applied to inter temporal data of loan disbursements of the selected bank. By applying Estimate … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,579 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurface Roughness Prediction Model in Machining of Carbon Steel by PCD Coated Cutting ToolsYusuf Sahin, A. Riza MotorcuThe surface roughness model in the turning of AISI 1040 carbon steel was developed in terms of cutting speed, feed rate and depth of cut using response surface methodology. Machining tests were carried out using PVD-coated tools under different cutting conditions. The surface roughness equations of cutting tools when machining the carbon steels were achieved by using the experimental data. … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociations of HSD17B1 Gene Expression with its DNA Methylation and Estradiol Level in Polycystic Ovary Syndrome Indonesian PatientsRina Puspita, Andon Hestiantoro et al.PCOS's origin and mechanism are still unknown. Epigenetics has been linked to PCOS in an increasing number of studies in recent years. The most extensively researched epigenetic alteration is DNA methylation. During organismal development, DNA methylation can control gene expression by altering transcription factor binding. The alterations in DNA methylation are directly associated with follicular development in PCOS. Studies show … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 8 Jan 2024 · 5,405 accessesView PDFCite
Research ArticleOpen accessIn the abstractHistochemical Study of Immature Blackbuck Pancreas in Al-Najaf, IraqWaleed J. A. Al-Kelaby, Zahraa S. M. Al Kaabi, Hany Akeel Al-Hussaniy et al.The histological makeup of the pancreas in immature male and female Iraqi blackbuck (Caprus hircus) has not been well described. We aimed to describe the histological features of the pancreas in immature male and female Iraqi blackbuck. Samples were collected from 20 immature male and female animals' pancreas, obtained from the Al-Najaf slaughterhouse. The samples were fixed in 10% neutral … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 11 Dec 2023 · 5,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractHuman Age Predication from Face Images Based on Combining Deep Wavelet Network and Machine Learning AlgorithmsZahraa Salam Abu Ghrban, Nidhal K. EL AbbadiDue to the numerous variances in face appearance, age estimation using facial images is a difficult subject. Many factors can affect the estimation of human age such as race, face post, gender, lifestyle, etc. By considering more factors, the optimum performance may be obtained. In this study, we proposed a method to predict the age of facial images. The proposed … …Journal of Computer Science, Vol. 19, Issue 5 · 5 May 2023 · 5,573 accessesView PDFCite
