Providing employees with protection and security is one of the key concerns of any organization. This goal can be implemented mainly by managing and protecting employees’ cars in the parking area. Therefore, a parking area must be managed and organized with smart technologies and tools that can be applied and integrated in an intelligent parking system. This paper presents the tools based on image recognition technology that can be used to effectively control various parts of a parking system. An intelligent automotive parking system is effectively implemented by integrating image processing technologies and an Arduino controller. Results show that intelligent parking is successfully implemented based on car ID image capture to meet the need for managing and organizing car parking systems. © School of Engineering, Taylor’s University.

This study investigates students' awareness and perceptions of m-learning and examines the factors affecting students' behavioral intention to adopt m-learning, by using a modified research model that integrate technology acceptance model (perceived usefulness and perceived ease of use) and unified theory of acceptance and use of technology (social influence) along with other factors (m-learning services and mobile limitations). In addition, control (gender, field of study, study level) and moderator variables (mobile capabilities, level of mobile usage, and frequent use of m-services) were introduced to verify the individual differences between respondents on the key factors affecting the adoption and usage of m-learning. Structural equations modeling and path analysis were used to test the hypotheses and the proposed model. The results revealed that perceived usefulness and perceived ease of use were found to be the primary factors driving students' intentions to use m-learning. Both m-learning services and social influence have positive effects on the acceptance of m-learning, while mobile limitations were found to be the main obstacle restraining students' participation in a m-learning environment. Most of the control variables yield no significant differences between students, but all the moderator variables were found to be significant determinants that can influence students to adopt m-learning. Overall, students have great potential to engage and integrate mobile technology into their educational environment. © 2016 Elsevier Ltd

This paper presents the experimental, numerical, and analytical investigations on the horizontal L-shape heat pipe for the notebook-CPU cooling. Simulations are carried out for both the 2-D and 3-D cases. In a 3-D model, the heat pipe as a whole is modeled based on the heat transfer by conduction. The heat pipe is assumed to be a conducting medium without taking into account the events occurring inside the heat pipe. A 2-D model based on the characterization of the working fluid inside the heat pipe is the other developed model. The 2-D finite element simulation is performed under natural and forced convection modes, by using ANSYS-FLOTRAN. Moreover, the design of experiment software is employed to optimize the coolant airflow rate and the heat input to get the best performance of heat pipe. The wall temperatures, velocity, and pressure distributions of the vapor and the liquid are analyzed. The heat inputs of the minimum thermal resistance in both natural and forced convection are found to be 20 and 35 W, respectively. The simulation and experimental wall temperatures are found to be a good match. Accordingly, the numerical solution is in agreement with the analytical solution in terms of vapor and liquid pressure drops. © 2011-2012 IEEE.

Many universities and institutes experience difficulty in training people to work with expensive equipments. A common problem faced by educational institutions concerns the limited availability of expensive robotics equipments, with which students in the didactic program can work, in order to acquire valuable "ha nds on" experience. Therefore, the Robot Simulation Software (RSS) nowadays is paramount important. This paper presents the development of a visual software package where a AL5B Robot arm has been taken as a case study. It utilizes Matlab/Simulink and AutoCAD as the tools for testing motional characteristics of the AL5B Robot arm. A robot model will be developed; the Forward, Inverse Kinematics, Velocity Kinematics "Jacobian" and Path Planning problems will be implemented and tested. The developed package will be used as an educational tool. We think that this work will increase the education, training, research and development possibilities for robotics classes in graduate and under graduate studies. © 2010 IEEE.

Structural stability and electronic properties of GaAs1-xPx (0.0≤x≤1.0) nanowires (NWs) in zinc-blende (ZB) (∼5≤ diameter ≤∼21Å) and wurtzite (WZ) (∼5≤diameter≤∼29Å) phases are investigated by first-principles calculations based on density functional theory (DFT). GaAs (x=0.0) and GaP (x=1.0) compound NWs in WZ phase are found energetically more stable than in ZB structural ones. In the case of GaAs1-xPx alloy NWs, the energetically favorable phase is found size and composition dependent. All the presented NWs have semiconductor characteristics. The quantum size effect is clearly demonstrated for all GaAs1-xPx (0.0≤x≤1.0) NWs. The band gaps of ZB and WZ structural GaAs compound NWs with ∼10≤ diameter ≤∼21Å and ∼5≤diameter≤∼29Å, respectively are enlarged by the addition of concentrations of phosphorus for obtaining GaAs1-xPx NWs proportional to the x values around 0.25, 0.50 and 0.75. © 2016 World Scientific Publishing Company.

As part of the ongoing research on finned L-shape heat pipes for electronic cooling, the present work focuses on the optimization of the thickness and permeability of wick structure of L-shape heat pipe, using different working fluids. D-Optimal Designs Software is used to obtain the optimal solution to align the competing parameters such as the working fluid properties, thickness of the wick and the type of wick structure. The optimization results yielded that a wick thickness of 0.52 mm and permeability of 1.39E-11 m2 with water as a working fluid could produce the minimum temperature difference between the evaporator and condenser sections of 9.56 °C and liquid pressure drop of 5730 Pa, which could increase the heat transport capability from 35 W to 43 W. These results reveal that the performance of L-shape heat pipe in terms of heat transport capability is improved by 20%. © 2014 Jordan Journal of Mechanical and Industrial Engineering.

In the last few years the numerical methods for solving the fractional differential equations started to be applied intensively to real world phenomena. Having these things in mind in this manuscript we focus on the fractional Lagrangian and Hamiltonian of the complex Bateman - Feshbach Tikochinsky oscillator. The numerical analysis of the corresponding fractional Euler-Lagrange equations is given within the Grünwald - Letnikov approach, which is power series expansion of the generating function. © 2013 Chinese Physical Society and IOP Publishing Ltd.

Abstract Structural stability and electronic properties of bare and hydrogenated GaP nanowires in zinc-blende and wurtzite phases have been investigated using first-principles calculations based on density functional theory. It is determined that relaxation of the hydrogenated GaP nanowires is very small compared to that of their bare ones. The wurtzite structural hydrogenated GaP nanowires are found more stable than the zinc-blende structural ones by cohesive energy calculations. It is obtained that all the bare and hydrogenated GaP nanowires in zinc-blende and wurtzite phases considered in this work have semiconductor characteristics. The confinement effect, by which the energy gaps are increased with the decrease of the diameter, is demonstrated for the hydrogenated GaP nanowires in both zinc-blende and wurtzite phases. In contrast to the hydrogenated wurtzite GaP nanowires, the hydrogenated zinc-blende ones are found direct band gap materials for diameters in the range of ∼9< d f < ∼ 21 Å. © 2015 Elsevier B.V.

The first-principles calculations based on Density Functional Theory (DFT) within generalized gradient approximation (GGA) of Engel-Vosko-Perdew-Wang and modified exact exchange potential of Becke-Johnson have been introduced for the structural and electronic properties of the ScxAl1-xN alloys, respectively. The present lattice constants calculated for the ScAlN alloys and the end compounds (AlN and ScN) are found to be in very good agreement with the available experimental and theoretical ones. The stable ground state structures of the ScxAl1-xN alloys are determined to be wurtzite for the Sc concentration less than ∼0.403 and rock-salt for the higher Sc concentrations. The present electronic band structure calculations within Becke-Johnson scheme are found to be capable of providing energy band gaps of the AlN and ScN compounds very close to the ones of the available experiments and expensive calculations. According to the calculations of Becke-Johnson potential, the ScxAl1-xN alloys in the wurtzite and zinc-blende structures are direct band gap materials for the Sc concentrations in the ranges of (0.056 ≤ x ≤ 0.833) and (0.03125 ≤ x ≤ 0.0625, 0.375 ≤ x ≤ 0.96875), respectively. However, the ScAlN alloys in the rock-salt phase are determined to be direct band gap materials for total range of the Sc concentration considered in this work. While the energy gaps of the RS-AlScN alloys are found to be extending from near ultraviolet to near infrared with a large (negative) bowing, the ones of the WZ-AlScN and ZB-AlScN alloys are determined to be varying in a small energy range around near ultraviolet with a small (negative) bowing. © 2013 World Scientific Publishing Company.

In the current study, the effects of the wick structures and working fluids characteristics on U-shape heat pipe performance were numerically presented. A two-dimensional FEM simulation was performed on U-shape heat pipe to analyze the temperature and the pressure distributions inside the heat pipe. In order to reduce the pressure arising in the area of the wick to increase heat transport capability at the liquid-wick region, a comparative numerical study was made by using methanol and water as working fluids with sintered powder and screen mesh wicks. The simulation was performed by using ANSYS/FLOTRAN software with heat input of 10 W at forced convection. The results showed that the use of sintered copper powder wick resulted in a small temperature difference between the evaporator and condenser compared to screen mesh wick. The use of screen mesh wick caused a decrease in the pressure drop in liquid-wick region while the use of methanol as working fluid increased the liquid pressure drop. © 2013 Elsevier Ltd.
