Research ArticleOpen accessIn the abstractAnt Colony Optimization for Solving Solid Waste Collection Scheduling ProblemsZ. Ismail, S. L. LohProblem statement: Southern Waste Management environment (SWM environment) is a company responsible for the collection and disposal of solid waste for the city of Johor Bahru, a city with over one million populations. The company is implementing an integrated solid waste management system where it involved in the optimization of resources to ensure the effectiveness of its services. Formulating this … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 8,020 accessesView PDFCite
Research ArticleOpen accessIn the abstractGroundwater in the Urban Environment: Management Needs and Planning StrategiesStefano Lo Russo, Glenda TaddiaProblem statement: Over the past thirty years urban transformations, such as urbanization, suburbanization, dis-urbanization and re-urbanization processes, have modified the subsurface conditions of Torino (NW Italy). In order to contribute to the solution of the problems concerning groundwater the conceptual model for the groundwater flow system, the schematization of the aquifers boundaries and the estimation of basic hydrogeological parameters are … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractSerological Evaluation of Brucella abortus S99 Lipopolysaccharide Extracted by an Optimized MethodAli Sharifat Salmani, Seyed Davar Siadat, Mohammad Reza Fallahian et al.Problem statement: Brucellosis is a globally found infectious disease and there is no licensed vaccine against human brucellosis. The present study carried-out to evaluate the potency of our modified extracted lipopolysaccharide (LPS) of B. abortus to elicit specific anti-Brucella antibodies in animal model (Rabbit) as a part of a candidate vaccine for brucellosis. Lipopolysaccharide is one of the main virulence … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 9,083 accessesView PDFCite
Research ArticleOpen accessIn the abstractSource Couple Logic (SCL): Theory and Physical DesignMohamed Azaga, Masuri OthmanThis study describes and presents the analysis for the Source-Coupled Logic (SCL) inverter as will as the effect of submicron layout parasitics. The SCL inverter circuit model and its operation is defined. The analysis for the SCL is carried from the point of view of input/output voltage characteristics and the effect of noise margin. The inverter gate delay model is … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2008 · 7,472 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimal Parameter Tuning in a Predictive Nonlinear Control Method for a Mobile RobotD. Hazry, M. SugisakaThis study contributes to a new optimal parameter tuning in a predictive nonlinear control method for stable trajectory straight line tracking with a non-holonomic mobile robot. In this method, the focus lies in finding the optimal parameter estimation and to predict the path that the mobile robot will follow for stable trajectory straight line tracking system. The stability control contains … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Apr 2006 · 7,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractPublicly Funded Education and Human Capital in the Presence of a Convex-Concave Education FunctionBinh Tran-Nam, Công Nghê TruongThis study investigates an aggregative optimal growth model in which short-lived individuals obtain their labour skill through education. The process of human capital formation is described by an increasing, convex-concave education function relating the success rate to the educational expenditure per student. The cost of education is publicly funded by an income tax imposed on adult workers. Despite the apparent … …American Journal of Applied Sciences, Vol. 2, Issue 13 · 7 Dec 2005 · 7,872 accessesView PDFCite
Research ArticleOpen accessIn the abstractNonlinear Analysis of RC Box Culverts Resting on a Linear Elastic SoilDaniele Baraldi, Fabio Minghini, Enrico Tezzon, Nerio TulliniIn the analyses presented, the soil-structure interaction is accounted for by means of a FE-BIE approach, in which the structure is modelled with displacement-based beam finite elements, whereas the boundary between structure and substrate is described in terms of surface tractions by means of a boundary integral equation incorporating a suitable Green's function. This mixed formulation ensures full continuity between … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 8 Feb 2018 · 12,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractCyclic Instability of Shape-Memory Alloys in Seismic Isolation SystemsFilipe Amarante dos Santos, Corneliu Cismasiu, Francisco Braz FernandesShape-memory alloys are being progressively introduced as kernel components in seismic retrofitting devices for civil engineering structures. In order to control the instability associated with the first mechanical cycles, a training procedure is usually implemented, which stabilizes the superelastic behavior of the alloy. This paper addresses the characterization of the cyclic behavior of an austenitic NiTi alloy with emphasis on … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 7 Jan 2018 · 6,856 accessesView PDFCite
Research ArticleOpen accessIn the abstractTwo-Stage Estimation in Inverse Problems using Combined Wavelet Thresholding and Penalized Maximum LikelihoodRobert G Aykroyd, Hassan AljohaniInverse problems occur in a wide range of practical scientific investigations where the variables of interest are only observed indirectly, such as magnetic and seismic imaging in geophysics, electrical tomography in industrial process monitoring, or PET scanning in medicine. Linear inverse problems can be thought of as highly multivariate regression problems with strong multicollinearity where the aim is to interpret … …Journal of Mathematics and Statistics, Vol. 13, Issue 3 · 29 Sep 2017 · 7,928 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling of Rainfall Characteristics for Monitoring of the Extreme Rainfall Event in Makassar CityWahidah Sanusi, Usman Mulbar, Hendra Jaya et al.Flooding is a common problem that occurs in some regions of Indonesia, including Makassar city. In the planning of flood control, rainfall variables are very necessary as the frequency, intensity and duration of rainfall. The relationship of these variables can be expressed in a curve Intensity-Duration-Frequency (IDF). The objectives of this study are to identify the best fitting distribution of … …American Journal of Applied Sciences, Vol. 14, Issue 4 · 10 Apr 2017 · 7,801 accessesView PDFCite
