Research ArticleOpen accessIn the abstractSpeaker Identification: A Hybrid Approach Using Neural Networks and Wavelet TransformMuzhir Shaban Al-Ani, Thabit Sultan Mohammed, Karim M. AljeboryIn speaker identification systems, a database is constructed from the speech samples of known speakers. The approach implemented in this paper is hybrid, where the wavelet transform and neural networks are used together to form a system with improved performance. Features are extracted by applying a discrete wavelet transform (DWT), while a neural network (NN) is used for formulating the … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 7,072 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Voice-Based Door Access Control System Using Adaptive-Network-based Fuzzy Inference Systems (ANFIS) for Building SecurityWahyudi, Winda Astuti, Syazilawati MohamedSecure buildings are currently protected from unauthorized access by a variety of devices. Even though there are many kinds of devices to guarantee the system safety such as PIN pads, keys both conventional and electronic, identity cards, cryptographic and dual control procedures, the people voice can also be used. The ability to verify the identity of a speaker by analyzing … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 8,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractInternet Politics and Digital Divide Issues: The Rising of a New Electronic Aristocrats and Electronic MeticiansAthanasios I. BozinisThe use of Information and Communication Technologies (ICT) from the beginning of 1990 until today has brought important changes on function and structure of both public sector and governments. Within the framework of application and use of e-democracy, new technologies enhance the citizens’ democratic participation in public affairs, by using e-voting, e-ballot, while by using e-mail, citizens can develop and … …Journal of Social Sciences, Vol. 3, Issue 1 · 31 Mar 2007 · 8,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractGas Turbine Ontology for the Industrial ProcessesF. Z. Laallam, M. SellamiThe activity of supervision and control of the industrial processes is a very complex spot and require a great experiment because of the dynamic characteristics of the process. This experiment was acquired with the passing of years. What makes departure of an expert in retirement a great loss of the know-how. The problem thus consists to capture this know-how and … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 7,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Economic Feasibility of Rebuilding Al-Isra University Tunnel — Mechanical FactorsBassam Al-HelouEconomic feasibility is the cornerstone in the decision making on an economic venture. The more positive the economic signs, the less the risk and foreseen losses. This study throws light on some economic advantages of rebuilding Al-Isra tunnel, especially in terms of shortening the car/bus trip by six kilometers go and fro, and in terms of reducing the trip schedule … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,154 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating the Optimal Farm Size under Uncertainty: an Application of Real Options MethodologyAnastasios Ch. Michailidis, Konstadinos A. MattasFarm structure and optimal farm size have always attracted the interest of research as they constitute some of the intense problems of farm efficiency and farm income. Although several approached have been employed to handle with this problem a real options approach can significantly contribute on this matter. This article provides an empirical example of applying real options approach in … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 7,664 accessesView PDFCite
Research ArticleOpen accessIn the abstractConsumer Choice Prediction: Artificial Neural Networks versus Logistic ModelsChristopher Gan, Visit Limsombunchai, Mike Clemes, Amy WengConventional econometric models, such as discriminant analysis and logistic regression have been used to predict consumer choice. However, in recent years, there has been a growing interest in applying artificial neural networks (ANN) to analyse consumer behaviour and to model the consumer decision-making process. The purpose of this paper is to empirically compare the predictive power of the probability neural … …Journal of Social Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 8,441 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simple Approach for Building Cooling Load EstimationF. A. Ansari, A. S. Mokhtar, K. A. Abbas, N. M. AdamThe present work is to demonstrate how some very simple problems are made mathematically complex and seemingly tedious due to academic or business compulsions. There are some problems in which mathematical model are developed after making many simplifying assumptions. But, when it comes to solving these models, very sophisticated and complex schemes are applied. For such problems, dual policy does … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractConsidering Environmental Externalities in Technology Selection: the Case of Urban Buses for AthensDimitrios A. GeorgakellosThe present study proposes a procedure for considering the environmental externalities in technology selection decision-making, based on the outcome of Life Cycle Assessments. Currently, even if there are several methods available for technology selection and purchasing, almost all of them seem to ignore the external cost associated with the candidates. The main features of the proposed model are its simplicity … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,002 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordLeveraging Appreciative Intelligence for Positive Enactment in Times of Uncertainty: A Case Study of a Small Investment FirmSusan Schick Case, Tojo ThatchenkeryProblem statement: How do we develop a complex understanding of markets and environments? Are markets and environments concrete entities that exist “out there” or are they socially constructed by human imagination and intentional language use? Approach: Using a case study approach, the interactions in a small investment firm were analyzed to bring to surface the complex relationship among markets, enactment … …American Journal of Economics and Business Administration, Vol. 2, Issue 2 · 30 Jun 2010 · 7,555 accessesView PDFCite
