Research ArticleOpen accessIn the abstractTowards more Manageable Coastal Building; Initial Coastal Building Construction GuidelinesRoslan Talib, Mohd Z. SuliemanProblem statement: As we may not be aware that the coastal construction is different from inland construction. Building in a coastal environment is different from building in an inland area. In general, buildings in coastal areas must be designed and built to withstand higher loads due to its more extreme conditions. Nowadays, the issue of global warming, uncertainty of global … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 22 Aug 2011 · 8,650 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Vegetative Induced Deformation in an Unsaturated SoilNazri Bn Ali, Mu’azu Mohammed AbdullahiProblem statement: Tree root water-uptake increases soil strength by increasing the soil matric suction due to pore pressure dissipation in a soil mass, inducing increases in vertical total stress or water extraction, the effective stress to which the soil strata is subjected to may also increase. This causes volume change which might be detrimental to geotechnical structures and shallow foundation. … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,135 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordAnalysis and Synthesis of Mechanisms with Bars and Gears Used in Robots and ManipulatorsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Bars and gears are used everywhere today, but a wide range of uses is robotics and mechatronics. Since ancient times, automations and mechanization have been used with mechanisms consisting of chains of bars and gears. These were obviously used for the purpose of transmitting the movement and its transformation, that is to say, as a mechanical transmission. Gear and bar … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 20 Dec 2017 · 7,052 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordIncorporation of Cellulose into a Chew Treat for Dogs Increases Elasticity and Chewing TimeA. C. BeynenProblem statement: We have reported earlier that administration of a treat containing a special cellulose preparation (Arbocel BWW40®), instead of a control treat without cellulose, diminishes the clinical signs of periodontal disease in dogs. Based on the physical characteristics of cellulose preparation, we hypothesized that treats with cellulose have greater elasticity and induce longer chewing time, leading to more mechanical … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 3 · 20 Oct 2011 · 7,874 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffects of Carcass Weight and Muscle on Texture, Structure, Rheological Properties and Myofibre Characteristics of Roe DeerJoanna Żochowska-Kujawska, Kazimierz Lachowicz, Małgorzata Sobczak, Leszek GajowieckiMyofibre characteristic, texture, structure and rheological properties of selected muscles (BF, SM and L) of roe deer of different carcass weight were compared. Muscle texture and rheological properties was determined with the TPA and relaxation test, respectively, performed with a Instron 1140 device. Fibre type percentage and structural elements (muscle fibre cross sectional area and perimysium thickness) were measured in … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,579 accessesView PDFCite
Review ArticleOpen accessAll words, across the recordMechanisms With Rigid MemoryRelly Victoria Virgil PetrescuAlong with gears, distribution mechanisms are the most widely used mechanical transmissions used over the past 300 years and will continue to be the most widespread in all industrial fields but also in other technical areas. For this reason, it was considered necessary this work, which tries to add a brick to the permanent construction of rigid memory mechanisms used … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 19 Jul 2019 · 6,162 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPre-Reinforcement Sprinkle FRP for Reinforced-Concrete Beams against Earthquakes, FRP: Consumption in Civil EngineeringMoein Zargar, Hossein Gholami, Hossein Norouzi et al.Nowadays, the reinforcement is used by green concrete, coated steel sheet, reinforcement, fiber reinforced such as carbon, aramid, and glass as earthquake reinforcement methods for concrete structures. regard the reinforcing structures and buildings against earthquake forces in the future, only simple methods for lowering prices should not be considered and the earthquake behaviors should be completely transparent. In this article, … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 2 · 26 Jun 2019 · 7,344 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMachine Motion Equations Presented in a New General FormatNicolae Petrescu, Florian Ion Tiberiu PetrescuConsidering the increased importance of robots nowadays, when no large factory or factory can work without robots, we want to present in the work the motion equations of the machine in an original form, both in terms of aspect and their deduction. The machine's motion equations can be used in dynamic calculations at any type of machine, whether it be … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 22 May 2019 · 6,131 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
