Research ArticleOpen accessEvery word in the titleThe Operational Features of Pumping Stations Equiped with Parallel-Connected Centrifugal Pumps for Land-ReclamationKhalid S. Al-RababaThe required water supply of a pump could be provided by means of different combinations of pressure piping and pumping units at different operational costs. The basic indices describing the operational modes for the individual and group pumping units, including the values of the efficiency, are computed. The adequacy of the calculational results that based on the developed mathematical models … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,802 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Fault-Tolerant Majority Gate Architecture for Robust Operation in QCA-Based Nano CircuitsAmi Patel, Vrushank Shah, Dipti KhurgeQuantum Dot Cellular Automata (QCA) is one of the promising alternatives to the traditional CMOS technologies for next-generation nanocomputing, which can be integrated at a higher density and has a higher possibility of low power consumption. Fabrication defects, environmental noise, and fault tolerance, especially in larger circuits, are challenging for practical implementation of QCA circuits. A new Fault-Tolerant Majority Gate … …Journal of Computer Science, Vol. 22, Issue 7 · 7 Jul 2026 · 1,194 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of the Operation of DC Interconnected Households PV under Weather ConditionsGilbert Ngoma, Maryse Dadina Nkoua Ngavouka et al.Installing Photovoltaic (PV) systems is becoming a viable solution for rural areas, with an innovative approach consisting of interconnecting autonomous PV-powered households. This study analyses the performance of interconnected autonomous PV households under different weather conditions using the Matlab Simulink R2016a software. Over and above this interconnection analysis, in this study, a new mathematical model to predict PV power is … …American Journal of Engineering and Applied Sciences, Vol. 18, Issue 1 · 4 Jan 2025 · 6,207 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Novel Approach to Wheelchair Design and Operation Using Multi-Function ControllerJamal I. Al-NabulsiAn electric multi-function controlled wheelchair is designed and fully tested. This wheelchair is controlled by several physiological variables namely; voice, head movement, finger bending, breathing pressure and Electrooculography (EOG). The patient has the choice to use any of these variables to control the wheelchair. The voice command is recorded by a voice recognition module with its microphone, whereas, the head … …Journal of Computer Science, Vol. 16, Issue 7 · 25 Jul 2020 · 6,762 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Validation of a Mathematical Model of the Operation of a Hydraulic Ram Pump with a Springs SystemAndriamahefasoa Rajaonison, Hery Tiana RakotondramiaranaWater pumps, which usually require fuels or power, are for carrying water from water sources to a facility, generally a household or a farm in the countryside. The present study consists of conducting an experimental validation of a mathematical model that was developed in a previous work for simulating the functioning of a new form of the hydraulic ram pump, … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 14 Jun 2020 · 7,702 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Investigate the Effect of Burner Geometry on the Operation Window of the BurnerJameel Al-Naffakh, Mohammed Al-Fahham, Qahtan A. AbedThe purpose of this paper is to conduct an experimental study of a swirl burner with different lengths for a fixed diameter. Three models of rim length (5 cm, 10 cm and 15 cm) were taken. The results show that any change in the ratio of length to diameter will affect the flame position and structure of the downstream. It … …Energy Research Journal, Vol. 10, Issue 1 · 30 Oct 2019 · 7,428 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDynamic Simulation and Optimum Operation Strategy of a Trigeneration System Serving a HospitalFrancesco Calise, Massimo Dentice d'Accadia, Luigi Libertini et al.This paper presents a numerical analysis of a trigeneration system in a hospital, aiming at determining the cost-optimal operating strategy as a function of the energy demands to be matched. The system includes: A natural gas fired reciprocating engine, heat exchangers for waste-heat recovery, a single-stage LiBr-H2O Absorption Chiller (ACH), a cooling tower, pumps, a backup boiler, a backup vapour-compression … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 29 Aug 2016 · 8,177 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe "New Settlers": Results of a Bacteriological Survey During the First 6-Months Operation Period of an Internal Medicine Ward in a Tertiary HospitalGad Segal, Adi Brom, Erez RamatiDuring the first six months of operating a new Internal-medicine ward in a tertiary hospital, a prospective survey, tracking both patient and environment bacteriological samples taken, was conducted. The motive behind the study was to establish the pattern in which environmental colonization is transmitted to the hospitalized patients and vice versa, thus defining the nosocomial pathogens that are typical to … …American Journal of Infectious Diseases, Vol. 9, Issue 4 · 27 Nov 2013 · 6,785 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Design of Blade for Small Horizontal-Axis Wind Turbine with Low Wind Speed OperationParamet Pathike, Thanad Katpradit, Pradit Terdtoon, Phrut SakulchangsatjataiIn Thailand, the average wind speed throughout the country is comparatively low for normally-available wind turbine. Designing of a new blade suitable for applications in the average wind speed of 3-7 m sec-1 is, thus, a main objective of this study. High torque has to be obtained properly to generate electricity. In order to design and evaluate performance, our mechanical … …Energy Research Journal, Vol. 4, Issue 1 · 26 Aug 2013 · 8,063 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnvironmental and Safety Accidents Related to Blasting OperationLazar Kricak, Vladislav Kecojevic, Ivan Jankovic et al.The blasting process remains a potential source of numerous environmental and safety accidents. The majority of these accidents were contributed to the flyrock and lack of blast area security.
