摘要：Nowadays Quantum Cellular Automata (QCA) as the leading technology in design of microelectronic systems has been raised. With respect to high velocity and density in low power and also simple concepts, this technology is a viable alternative to CMOS technology. In collector design, the primary component of each processor is very important. Due to the small elements in this technology, failure rate in manufacturing process technology is very high. In the other hand, the simulation shows that the intersection point of two wires is one of the critical points in QCA circuits. This means that defects in the manufacturing process around these points can cause malfunction in the circuit performance. In this paper, a collector in cross sections of wire in his new method used higher reliability against defects during manufacturing has been developed. QCA Designer software is used to simulate the case study system.

摘要：e-Governance facilities are being used nowadays by citizens in various Government projects of the country. But the integration of mobile technologies with the e-Governance projects can lead to more human interaction and benefits for the society as a whole. This will result in having more impact on the lives of the common citizens and increase in awareness of such e-Governance projects. The paper introduces the features, technologies and design of the Android mobile device application, mobileLoanapp for the customer (client) of the bank for the loan approval process. The e-Land record information system has been designed and implemented with Google Map using Mobile Commerce by developing this mobile app. This m-app has been developed so as to provide improved and flexible e-Governance facility to the common citizens of the country. The proposed system if adapted will pave the way for the real-time applications to be embedded with the e-Governance facilities. This paper presents the overall system architecture along with its functional components and scope of the very appealing m-application (mobileLoanapp) for bank loan approval process in interconnection with the land server (part of Farad Kendra’s). The overall advantages of the proposed m-app have also been determined in comparison to the existing e-Governance system, giving a viable option to adopt and make use of integration of mobile technologies for providing e-Governance through this m-app.

摘要：Visually impaired people face difficulties in interacting and gaining full advantage of computers. Recently, and with the fast evolution in technology, researchers proposed to give the blinds the ability to take advantage of these advancements. Accordingly, designers and engineers started working on projects that relate input and output devices to the computers in order for the blind individual to have full control of the hi-tech machines. However, investments in these kinds of hardware presented complexity in the design, in addition to the high cost imposed by the devices used. The project’s objective is to design and develop a Multi-Lingual Braille System Output Device for the visually impaired individuals that enable them to access and read texts from a computer. The device acquires both English or Arabic texts and displays them using controlled piezoelectric Braille cells. It also has the ability to produce a sound that matches the displayed characters. The control of the cells is done via Programmable Interface Controller (PIC) microcontroller. The interaction between the device and the computer is done through the Universal Serial Bus (USB). C# is the language used to write the program responsible for controlling this interaction. The continuous development of such devices is essential for the visually impaired to keep up with the technological advancements. The main advantages of this system are its low cost, the added multi-lingual, and the audio features. In addition, many features can be added so as to satisfy the users’ needs, such as adding new languages and Grade 2 Braille System.
