Performance Model for a Conservative Distributed Simulation Environment Using Null Messages to Avoid Deadlock
No full textA conservative distributed simulation requires all logical processes (LPs) to follow the causality constraint requirement. This implies that all event-messages are processed in strictly timestamp order. Apart from the timestamp of each event generated by LPs, synchronization between all LPs is the second most important requirements. Finally, there must not be a deadlock in the distributed environment. A deadlock may occur when there is no events present in the queue of LP. In such case, to avoid deadlock, Chandy-Misra-Bryant presented an algorithm called Null Message Algorithm (NMA) [3]. These null messages are passed as an event-message to other LPs and it stored in one of queues of LPs. This null message indicates that till the time stamp of that null message, all other events in the queue which have lesser time stamp than null message’s time stamp are safe to process. It means that there won’t be any arrival of any events from that logical process until current simulation time is equal to the time stamp of the null message. With the time stamp of the null message, a Lookahead value is added to the time stamp of that null message. This Lookahead value can be measure on certain kind of parameters such as delay to transmit a message, propagation delay, etc. therefore, calculating value of Lookahead is the most important part as Lookahead value affects the performance of the conservative distributed event simulation. Proper value of Lookahead can reduce the number of null messages which decreases the traffic of the network. In this paper, we demonstrate some calculation on the Lookahead which shows the performance of the distributed event simulation

Energy Efficient Military Mobile Base Station Placement
No full textThis research deals with an energy efficient network for military mobile base station placement. The proposed method is based on minimizing the energy loss of military communication networks where the base station is moving along a preset path and the users are constantly moving in an independent speed and direction. It takes into account the free space loss and the knife edge effect for the energy loss to establish a path weight for the shortest path model. Then, it evaluates the neighboring points to the base station for the energy loss of the network in order to find the position at which the minimum energy loss occurs. The results show a clear energy saving advantage when compared to Lloyd-Max’s method
Design and Optimization of Piezoelectric Dual-Mode Micro-Mirror
No full textThe final publication is available at www.springerlink.comMEMS micro-mirrors have been widely used in optical communication, projection display, and microscanner, etc. Various MEMS micro-mirror devices have been reported. In this paper, the design of a bulk-micromachined MEMS piezoelectric dual-mode micro-mirror is proposed. The working principle of the dual-mode micro-mirror device is analyzed. Based on the analysis, a set of optimized design parameters of the micro-mirror is suggested. Theoretical analysis shows that the proposed micro-mirror can deflect for a maximum displacement of 2.5 μm in its piston mode, and tilt for a maximum angle of 4.88º in its torsional mode. The fabrication flow of the MEMS micro-mirror is also suggested. The proposed micro-mirror has the advantages of large displacement and large tilt angle due to piezoelectric activation. The PZT actuated micro-mirror (PAM) also leads to improved linearity in tilting angle and piston displacement. Further, fast response of the PZT unimorph on the applied actuation voltage ensures wider operation bandwidth of the PAM in contrast to thermal activated micro-mirrors.http://link.springer.com/chapter/10.1007%2F978-90-481-9151-2_7
Improving teaching tools and techniques of teaching graduate engineering courses based on students’ learning styles and multiple intelligences
No full text© ASEE 2009Our study proposes to improve teaching tools and techniques of teaching graduate engineering courses using students’ Learning Styles and Multiple Intelligences (MI). Thirty volunteers answered commercially available Learning Style and MI tests in our Electrical Engineering department. Learning styles are grouped as visual, auditory, and kinesthetic (VAK) and are determined by the VAK learning style test. Learning styles are reflected in different academic strengths, weaknesses, and skills. Studies show that the differences between learning styles will affect both a person’s choice of profession and their success in this profession, both in education and in the world of business. People who work at something that fits their learning style have a better chance of becoming successful in it
