Firstly, the deserved significance and the need for the above-mentioned system is discussed, which motivates the researchers towards its development. The discussion elaborates on the fact that it goes beyond the point where other navigation systems reach their limits. What follows is a brief introduction to the applications of the geomagnetic field. Secondly, all ideas of methodologies have been introduced. The choice of method has been discussed, taking into consideration the behavior of animals concerning the geomagnetic field. Lastly, the most feasible way of achieving the system has been complemented with a mathematically-supported discussion.</p> 2020-08-06T00:00:00+0430 Copyright (c) 2020 Advanced Journal of Science and Engineering http://ajscieng.com/index.php/ajse/article/view/ajse2013074 Lithium Adsorption at the C20 Fullerene-Like Cage: DFT Approach 2020-05-25T15:47:28+0430 Kun Harismah kun.harismah@ums.ac.id Osman Murat Ozkendir ozkendir@gmail.com Mahmoud Mirzaei mdmirzaei20@gmail.com <p>Adsorption of neutral and cationic forms of lithium (Li) atom have been examined at the surface of pristine C<sub>20</sub> and boron/nitrogen doped (C<sub>12</sub>B<sub>8</sub> and C<sub>12</sub>N<sub>8</sub>) fullerene-like cages by density functional theory (DFT) calculations. All of singular cages have been first optimized and their complex formations with each of Li or Li<sup>+</sup> atoms have been examined, subsequently. The spherical structures of all three cages have been approved and the surfaces have been adequate for Li/Li<sup>+</sup> adsorption processes. The C<sub>12</sub>N<sub>8</sub> cage has been seen the most proper one for the purpose based on adsorption distances and the corresponding values of binding energy. Generally, the neutral Li atom has been seen to be better adsorbed at the surface of all three cages in comparison with cationic Li<sup>+</sup> atom. Examining the electronic orbitals of models indicated that the cages could yield a sensing behavior for differential diagnosis of Li/Li<sup>+</sup> adsorptions based on recording the changes of electronic orbitals at the cage structures as an advantage further than containing capability. Finally, based on the obtained computer-based data, C<sub>20</sub> fullerene-like cage could be considered for the case of Li adsorption problem in further studies.</p> 2020-08-06T00:00:00+0430 Copyright (c) 2020 Advanced Journal of Science and Engineering http://ajscieng.com/index.php/ajse/article/view/ajse2013080 Energy Harvesting from Wind by Piezoelectric for Autonomous Remote Sensor 2020-05-07T22:55:58+0430 Hamid Soleimanimehr soleimanimehr@srbiau.ac.ir ZohrehSadat Hosseini ZohrehSadatHosseini@gmal.com Mahdi Habibi MahdiHabibi@gmal.com Behnam Mostajeran Goortani BehnamMostajeranGoortani@gmal.com <p>Reduction in fossil fuels sources in earth has caused the humans to think about using renewable energies such as wind. Collecting precise data from wind and particularly its speed is the most important step in using the wind energy as power plants. In this article, a system has been designed, analyzed, and fabricated to use wind energy by applying a piezoelectric convertor to supply the required power for a remote sensor network and wind measurement. Thus, the efficiency of the system is analyzed by performing some practical experiments. The developed system in this experiment is capable of producing 245 microwatt of energy per 200 kilo ohm resistance in an 11 m/s wind speed by using only one single piezoelectric convertor. Piezoelectric Sensor with two piezoelectric needs more force to reach the piezoelectric break point and optimized wind speed value is equal or greater than 14 m/s. In this case, the internal resistant value for piezoelectric is doubled (400 kilo ohms) and the value of produced electrical power at wind speed of 14 m/s and resistant load of 400 kilo ohms is equal to 483 microwatt. Also, it works as a sensor for measuring wind speed by producing pulses in different speeds. Therefore, it would be possible to measure wind speeds in remote areas and also wind speeds higher than the threshold level and to send alarms in warning systems in cases of thunderstorms.</p> 2020-08-06T00:00:00+0430 Copyright (c) 2020 Advanced Journal of Science and Engineering http://ajscieng.com/index.php/ajse/article/view/ajse2013086 Smart Home Automation Using ATMEGA328 2020-05-22T01:57:54+0430 Muhammad Umer umerr1999@gmail.com Muhammad Miqdad Khan mmk08101997@gmail.com <p>Automation is one of the applications of control systems and information technologies to cut back the necessary works for human in the assembly of products and services. In the field of industrialization, automation could be a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the muscular necessities of work. In addition, automation greatly decreases the necessity for human sensory and mental requirements. The use of automation is increasing day by day in daily experiences and in the world economy. The idea of home automation has been a crucial issue in several publications and residential appliances corporations. Home automation could be a house or living setting that contains the technology to permit devices and systems to be controlled mechanically. Remote and native management is helpful to stay home snug and to support either older or disabled individuals. Hereby, the most effective and easiest method to automate the home appliances are discussed in this work. Among many ways and things to be automated, this paper mainly comprises of three things; Bluetooth based home automation using Arduino UNO, sensing the brightness through photo-resistor and actuating accordingly and the last one is water level indicator. Both hardware and software implementations are discussed serially. The experimental and observation analysis is also given for all three systems, simulation-based circuits are also being introduced and some techniques and tools related to the algorithm that works on a microcontroller are also discussed.</p> 2020-08-08T00:00:00+0430 Copyright (c) 2020 Advanced Journal of Science and Engineering http://ajscieng.com/index.php/ajse/article/view/ajse2013091 An Optimized Single Motor 1 DOF Tendon-Based Transmission 2020-07-08T14:37:40+0430 Mahdi Ansari Mahdi.Ansari@gmal.com Shahram Etemadi Haghighi setemadi@srbiau.ac.ir Hamid Soleimanimehr Soleimanimehr@srbiau.ac.ir Mohammadreza Madanipour MohammadrezaMadanipour@gmal.com <p>Tendon based transmission is an efficient method for force and motion transference. Not only tendon-driven mechanisms provide dexterity and manipulability in various applications, but also they keep the structure of the mechanism light and the design delicate. Although tendon driven mechanisms are effective in driving systems with various degrees of freedom, they require either simultaneous control of parallel tendons which could be challenging or utilizing passive tendons that decreases the control over the mechanism. This paper presents a novel design for driving a planar 1 DOF joint by a single actuator. The mechanism benefits from a compound non-circular pulley which linearizes the non-linear relationship between the pulley and joint angle. The pulley enables the mechanism to operate without any controller while keeping all the tendons active which distinguishes it from the previous designs. The algorithm to derive the profile of the pulley is explained and the mechanism parameters are optimized to minimize the traction in the tendons and also to improve the precision of the mechanism. The pulley and a prototype of the mechanism have been synthesized in order to prove the authenticity of the design and to compare the test result to the algorithm outcome.</p> 2020-08-08T00:00:00+0430 Copyright (c) 2020 Advanced Journal of Science and Engineering http://ajscieng.com/index.php/ajse/article/view/ajse2013067 Nanotechnology for Science and Engineering 2020-07-21T00:21:34+0430 Mahmoud Mirzaei mdmirzaei@pharm.mui.ac.ir <p>Since the early days of carbon nanotube (CNT) discovery, several efforts have been dedicated to recognize the characteristic features of this novel material for applications in various fields of science and engineering employing both of computational and experimental procedures. Although the pure CNT has been seen interesting enough to be investigated, but other related nanostructures have been also arisen in addition to the pioneering CNT.</p> 2020-07-21T00:00:00+0430 Copyright (c) 2020 Advanced Journal of Science and Engineering
