Research ArticleOpen accessAll words, across the recordHarmonics Phase Shifter for a Three-Phase System with Voltage Control by Integral-Cycle Triggering Mode of ThyristorsI. Badran, A.L. Mahmood, M.T. LazimIn integral-cycle triggering mode of voltage control, subharmonic as well as higher order harmonic components are generated in the load voltage waveforms of a three-phase system. These harmonic components are found to be unbalanced in phase displacement. The correction of the unbalanced phase displacement angles of a particular subharmonic or higher order harmonic for this type of triggering is investigated … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,110 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMOTIONS STUDY OF A SINGLE CYLINDER HIGH SPEED SPARK IGNITION LINIER ENGINE WITH SPRING SYSTEM AS RETURN CYCLEA. Z.M. Fathallah, Semin, I. M. Ariana, I. GeriantoA single cylinder two stroke spark ignition conventional engine have been modified to linier engine with spring mechanism. Before develop the design of linear engine is necessary to analysis of motion. Although principle of combustion process in combustion chamber is the same in fact the oscillation movement is different. Simulation technique has been adopted to study both linear and conventional … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 17 Jan 2014 · 7,179 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAn Approach to the Performance and Efficiency Power Analysis on Embedded Devices Using AsteriskAdauto Cavalcante Menezes, Toniclay Andrade Nogueira, Edward David Moreno Ordonez, Admilson de Ribamar Lima RibeiroVoice over IP (VoIP) communication will dominate the computing world for years to come. In order to perform VoIP communication, it is necessary to encode and decode the voice. This process consumes the main computational resources, as an example, it is possible to mention the processor and memory. The telecommunication industries provide equipment with high purchasing prices, which makes the … …Journal of Computer Science, Vol. 14, Issue 7 · 2 Aug 2018 · 8,258 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordThe Experiment Study of Performance, Combustion Process and NOX Emission of Diesel Engine with EGR System Using Angle Globe ValveAguk Zuhdi Muhammad Fathallah, Achmad Maulana YasinExhaust Gas Recirculation (EGR) is technology to reduce NOX emission of diesel engine. This technology could circulate some exhaust gas into the combustion chamber. The adiabatic combustion temperature could decrease and reduce the reaction of oxygen in nitrogen. This method could inhibit the formation of NOX during the combustion process because NOX formation reactions occur at high temperatures. EGR has … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 7 Feb 2018 · 8,046 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordSpace ProbesRelly Victoria Virgil PetrescuA space probe is an unmanned space vehicle launched into space to study more or less distant different celestial objects: The Sun, the planets, dwarf planets and small bodies, their satellites, the interplanetary medium or the interstellar medium. A space probe is distinguished from other unmanned spacecraft that remain in Earth orbit. Space probes can take a large number of … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 21 May 2019 · 7,407 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordThe Yield of the Thermal EnginesNicolae Petrescu, Florian Ion Tiberiu PetrescuThis paper presents an algorithm for determining the dynamic parameters of the main classic mechanism of internal combustion engines. It shows the distribution of forces (on the main engine mechanism) to internal combustion engines. With these forces and together with the kinematic coupling speeds, the efficiency of the thermal engine is determined. The method applies separately for two distinct situations: … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 14 May 2019 · 6,191 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDynamics at Classical DistributionRelly Victoria Virgil PetrescuClassical distribution is the most used in rigid memory mechanisms adapted to four-stroke internal combustion engines such as Otto or diesel, as it was designed by Otto more than 150 years ago, without essential changes from its conception and up today. Since it was not yet possible to introduce the electric car to the industrial scale and today we have … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 26 Apr 2019 · 6,394 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEcosphere Protection through Green EnergyRelly Victoria V. Petrescu, Raffaella Aversa, Antonio Apicella et al.A systemic approach, comprising all research and development activities that support the expansion of eco-efficient industrial and social systems fulfilling market and social-cultural constrains, is required to accomplish the challenge for competitiveness and sustainability along with an increasingly dynamic and complex global scientific, industrial and cultural scenarios. Ecosphere protection through the implementation of green energy is becoming a daily technological … …American Journal of Applied Sciences, Vol. 13, Issue 10 · 18 Oct 2016 · 8,801 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMethod of Efficiency Improvement in District Heating SystemsAndrey Gennadiievich Batuhtin, Maxim Stanislavovich Bass, Sergey Anatoljevich Ivanov et al.The article determines application potential of solar energy in conditions of sharply continental climate. It presents an energy-efficient solar energy recovery scheme in district heating systems, allowing to reduce capital costs and maintenance charges and to increase degree of substitution of conventional sources of heat. Versatility of systems using this method results in its multi-zone application: From a cottage-type house … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 1 Feb 2016 · 7,521 accessesView PDFCite
