Research ArticleOpen accessIn the abstractMachine 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
Research ArticleOpen accessIn the abstractDynamic Models for Rigid Memory MechanismsRelly Victoria Virgil PetrescuThe paper presents a dynamic model that works with variable internal damping, applicable directly to rigid memory mechanisms. If the problem of elasticity is generally solved, the problem of system damping is not clear and well-established. It is usually considered a constant "c" value for the internal damping of the system and sometimes the same value c and for the … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 5,981 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating the Effect of Heat on Reinforced Concrete Frame Using Finite Element SoftwareReza Salehi, Abbas Akbarpour Nikghalb RashtiThe present paper examines the effect of heat on the reinforced concrete frame. A concrete frame with a specific geometric dimension has been modeled in ABAQUS finite element software and its loading capacity and other specifications, such as hardness and ductility, have been obtained. Then the concrete frame was heated under temperature 200, 400, 600, 800 and 1000°C and load … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 4 May 2018 · 8,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractWillingness to Pay for Water Hyacinth Control in NepalUmesh Khatri, Resham Bahadur Thapa-Parajuli, Uttam PaudelWater Hyacinth (WH) has become a growing problem across Asia, specifically in Nepal. Infestations of this weed have reached critical proportions in freshwater bodies, causing environmental, economic, agricultural and social problems. These problems have corresponding monetary values. This study elicits the willingness of visitors and local people to control WH in the Phewa Lake in Nepal. Considering three scenarios encircling … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 14 Nov 2018 · 8,189 accessesView PDFCite
Review ArticleOpen accessIn the abstractBiomechanically Inspired Machines, Driven by Muscle Like Acting NiTi AlloysAntonio Apicella, Raffaella Aversa, Florian Ion Tiberiu PetrescuThe Shape of the Memory Alloy (SMA) is a very promising class of metallic materials with interesting non-linear properties such as Pseudo-Elasticity (PE), memory (MEM) and damping capacity due to high mechanical hysteresis and internal friction. Research shows a bioinventory approach to Shape Memory Alloy (SMA) design, a class of intelligent materials capable of reacting to a pulse (thermal for … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 23 May 2018 · 8,279 accessesView PDFCite
Research ArticleOpen accessIn the abstractCracking of Reinforced Recycled Concrete SlabsFlavio Stochino, Luisa Pani, Lorena Francesconi, Fausto MistrettaThe results of an experimental investigation on cracking of fifteen reinforced recycled concrete slabs are presented in this paper. Five different recycled aggregates replacement percentages have been used for different mix design. First, the values of tensile strength, cylindrical compressive strength and modulus of elasticity of the concrete mixes have been determined. Then the deflection-load curve of the simply supported … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 1 · 5 Sep 2017 · 10,157 accessesView PDFCite
Research ArticleOpen accessIn the abstractStationarity and Cointegration between Health Care Expenditure and GDP for JordanRasha M.S. Istaiteyeh, Mohd Tahir IsmailThis paper explores the Granger-causality relationship between real GDP per capita and real health care expenditure per capita for Jordan during 1995 through 2013. The findings point out that the dominant type of Granger-causality is unidirectional. Furthermore, income elasticity of health expenditure is less than 1, which means that health care is a necessary good in Jordan. To this end, … …American Journal of Applied Sciences, Vol. 14, Issue 7 · 22 Jun 2017 · 7,820 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlexural and Tensile Characteristics of Micro Fiber-Reinforced Very High Strength Concrete Thin PanelsTaher M. Abu-Lebdeh, Ellie Fini, Monique LumpkinThe purpose of this research was to experimentally characterize the flexural and tensile characteristics of fiber-reinforced Very High-Strength Concrete (VHSC) panels. The panels were made with a unique mix of cementitous materials achieving compressive strength of 26,000 psi (180 MPa) or greater. VHSC panels were reinforced with polypropylene fibers of 1 inch (25.4 mm) in length and Polyvinyl alcohol (PVA) … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 17 Aug 2012 · 8,495 accessesView PDFCite
Research ArticleOpen accessIn the abstractProperties of Fly Ash Based Coconut Fiber CompositeK. Saravana Raja Mohan, P. Jayabalan, A. RajaramanThe present paper reports the results of a study undertaken in enhancing properties of fly ash concrete composites-FMCC with locally available natural fiber. In this context a composite with fly ash, concrete and treated coconut fibers-available in plenty in rural areas of India-can be a good proposition and with this background, experimental investigation to study the effects of replacement of … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 20 Feb 2012 · 9,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Experimental Comparison Between Demand Systems of Major Food Groups in Urban EconomicsMahmoud Daneshvar Kakhki, Naser Shahnoushi, Fatemeh RezapourProblem statement: This study examined the eleven major food groups demand for urban areas of Iran during1361-1386. Approach: AIDS, ROTTERDAM, CBS and NBR models was compare together and Sur method was applied for estimating of systems, too. Results: Results of study showed cream and fresh fruits have smallest and largest income elasticity, respectively. Also, cream, bread, dairy, egg, fresh vegetables, … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 6,991 accessesView PDFCite
