Research ArticleOpen accessIn the abstractTowards an Effective Personalized Information Filter for P2P Based Focused Web CrawlingFu Xiang-hua, Feng Bo-qinInformation access is one of the hottest topics of information society, which has become even more important since the advent of the Web, but nowadays the general Web search engines still have no ability to find correct and timely information for individuals. In this paper, we propose a Peer-to-Peer (P2P) based decentralized focused Web crawling system called PeerBridge to provide … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,825 accessesView PDFCite
Research ArticleOpen accessIn the abstractFault Detection of 3-Phase VSI using Wavelet-Fuzzy AlgorithmM. Rozailan Mamat, M. Rizon, M. S. KhannicheThe good knowledge and information about the fault mode behaviour of the PWM voltage source inverter is important to improve system design, protection and fault tolerant control. This paper develops a real-time condition-monitoring algorithm for 3-phase Pulse Width Modulation (PWM) inverter in fuzzy speed controlled induction machine. It is designed to detect and identify the transistor open-circuit fault and an … …American Journal of Applied Sciences, Vol. 3, Issue 1 · 31 Jan 2006 · 7,956 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Applicability of the Short-run Phillips curve to NamibiaCyril A. OgbokorIn this research, we invoke linear and logarithmic regression models to empirically test the validity of the Short-run Phillips curve for Namibia by relying on macroeconomic time-series data running from 1991 to 2005.Our results offer some support for the presence of the phenomenon of stagflation in Namibia. This is rather contradictory to the underlying philosophy of the original Phillips curve. … …Journal of Social Sciences, Vol. 1, Issue 4 · 31 Dec 2005 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractLinear Smoothing of Noisy Spatial Temporal SeriesValter Di Giacinto, Ian dryden, Luigi ippoliti, Luca RomagnoliThe main objective of the study is the development of a linear filter to extract the signal from a spatio-temporal series affected by measurement error. We assume that the evolution of the unobservable signal can be modelled by a space time autoregressive process. In its vectorial form, the model admits a state space representation allowing the direct application of the … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,311 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of X-Ray Diffractometry (XRD) for Identification of Fritillaria According to Geographical OriginWang Shujun, Yu Jinglin, Gao WenyuanFritillaria is a traditional Chinese herbal medicine for anti-tussive and expectorant use in China and some other Asian countries. The Fritillaria Chinese medicine material derived from different geographical origins is always difficult to discriminate each other. The objective of the study is to develop a nondestructive and simple method to identify five Fritillaria Chinese materia medica such as Fritillaria thunbergii … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,108 accessesView PDFCite
Research ArticleOpen accessIn the abstractUltrasonic Study and Physical Properties of Borotellurite GlassesW.M. Daud, H. Zainul, Z.A. Talib et al.A series of glasses (TeO2)x (B2O3)1-x with x = 0.6, 0.63, 0.65, 0.70, 0.73, 0.75, 0.78 and 0.80 were synthesized by rapid quenching. Longitudinal and shear ultrasonic velocity were measured at room temperature and at 5 MHz frequency. Elastic properties, Poisson’s ratio and micro hardness have been calculated from the measured density and ultrasonic velocity at room temperature. Estimated parameters … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 7,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Investigation of Flow Control by Suction and Injection on a Subsonic AirfoilM. H. Shojaefard, A. R. Noorpoor, A. Avanesians, M. GhaffarpourThis study presents a numerical study concerning flow control by suction and injection. The case studied is the flow field over a subsonic airfoil with four suction and injection slots on the suction side of the airfoil. Five different angles of attack, 0, 5, 10, 13.3 and 20 with the Mach number of 0.15 are studied. Three cases are studied … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,428 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnergy Flow in Agriculture: BangladeshM. S. Alam, M. R. Alam, K. K. IslamIn this paper, a qualitative energy flow analysis in Bangladesh agriculture has been made for a period from 1980-81 to 2000-01 to evaluate the impact of energy input to produce output. Human and animal muscle power and machinery energy for tillage operation, electricity and diesel energy for irrigation, fertilizer and pesticides energy for growth and protection are taken into account. … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 11,587 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation and Situation of Timber Harvesting Mechanization of Turkey and the Usage of Tractors in Timber ExtractionMurat Demir, Tolga OzturkIn this study is to summarize usage of tractors in timber extraction and major problems of mechanized timber harvesting in Turkey. Timber harvesting in Turkey is still carried out by manual methods due to economical, social and environmental constraints. Almost 80% of harvesting activities are mechanized in many developed countries while this value is only 5% in Turkey. Overall ratio … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractPreparation and Characterization of Hybrid Organic-Inorganic Composite Material: Polymerization of m-Aminobenzoic Acid-Intercalated Into Zn/Al-Layered Double HydroxidesRasheed M.A.Q. JamhourLayered double hydroxides of aluminum and zinc (Zn/Al-LDH’s) were synthesized directly by hydrolysis at room temperature as reported elsewhere. After characterization, the material was reacted with m-aminobenzoat anion (m-NH2C6H4COO-) which undergoes polymerization in the interlayer space; resulting in the formation of a matrix with polymeric organic macromolecule. The resulting material along with the host LDH’s compound of Zn/Al-Cl was characterized … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 6,586 accessesView PDFCite
