An Industry Assessment: Are Aircraft Dispatchers In A Holding Pattern?, Georgiann Sailer

Theses and Dissertations

This industry assessment provided an in-depth view of the aircraft dispatcher industry. An assessment of the industry was needed to project the future of the aircraft dispatcher profession, as well as indicate the necessity of additional aircraft dispatcher training facilities in the United States. The position of an aircraft dispatcher originated in 1938 as a result of numerous aircraft accidents. It was believed that the repeated accidents occurred due to the lack of ground assistance to the pilot, therefore a new Airman Certificate was created, the aircraft dispatcher certificate. Some of the duties of an aircraft dispatcher include aircraft navigation, …

A Combined Routing Method For Ad Hoc Wireless Networks, Zhenhui Jiang

Dartmouth College Master’s Theses

To make ad hoc wireless networks adaptive to different mobility and traffic patterns, we studied in this thesis an approach to swap from one protocol to another protocol dynamically, while routing continues. By the insertion of a new layer, we were able to make each node in the ad hoc wireless network notify each other about the protocol swap. To ensure that routing works efficiently after the protocol swap, we initialized the destination routing protocol's data structures and reused the previous routing information to build the new routing table. We also tested our approach under different network topologies and traffic …

An Ethnographic-Case Study Of Beliefs, Context Factors, And Practices Of Teachers Integrating Technology, Julie Angers, Krisanna L. Machtmes

The Qualitative Report

This ethnographic-case study explored the beliefs, context factors, and practices of three middle school exemplary teachers that led to a technology-enriched curriculum. Findings suggest that these middle school teachers believe technology is a tool that adds value to lessons and to students learning and motivation. Due to a personal interest in technology, these teachers are self-taught and apply for grants to acquire new hardware and software. They receive support for release time to continue with ongoing professional development, which has helped to change their teaching strategies from teacher-centered to student-centered. They are not afraid to take risk using trial and …

Design And Implementation Of A Single Layer Feed Forward Neural Network Using Stand-Alone Architecture Fpgas-Based Platform, Waleed A. Mahmood, Monther H., Mothana H.

Iraqi Journal of Computers, Communications, Control and Systems Engineering

A single layer feed-forward neural network are proposed and implemented using the schematic editor of the Xilinx foundation series 2.1i. First the mathematical model of the data set (weights and inputs) is presented in a matrix multiplication format. Secondly the five design stages are presented and implemented without using the finite state machine, which control the processes of the forward propagation phase, error calculation, and the training algorithm. Finally the design can be optimized to decrease the total execution time and to minimize the cost, which eventually will increase the performance and improve the function density.

A Proposed Design For The Broadband Microwave Distributed Amplifiers, Ali A. Ali, M. S. Abdulwahaab, Azad Raheem Kareem

Iraqi Journal of Computers, Communications, Control and Systems Engineering

In this paper, a new method for the design of the broadband RF/microwave amplifiers employing distributed amplification is presented. It proposes to use stages with asymmetric lumped elements (inductances and capacitances) in the gate and drain circuits of the amplifier instead of symmetric elements in order to control the frequency response and to achieve a flat gain over a large bandwidth. The need for impedance matching problems is also solved. Simulation result obtained demonstrates that the new design gives better frequency response as compared to the conventional distributed amplifiers even without optimization

A Dynamic Economic Dispatch Solution Method Using Hopfield Neural Network, Q. M. Alias, F. Ben Hameda

Iraqi Journal of Computers, Communications, Control and Systems Engineering

This paper analyzes and tests a proposed neural network (NN) to solve the Dynamic Economic Dispatch (DED) as part of the unit commitment problem. The proposed NN is a fast and direct computation solver using a Hopfield model for solving the dynamic economic dispatch problem of thermal generators which is a dynamic optimization problem taking into account the constraints imposed on system operation by generator ramping rate limits. Formulations for solving the ED and DED problems are explored. Through the application of these formulations, direct computation instead of iterations for solving the problem becomes possible. Not like the usual Hopfield …

Digital System For Aircraft Attitude Measurement, Moayad Shawqi M., M. Al-Faysal, Haider Khudher Lateef

Iraqi Journal of Computers, Communications, Control and Systems Engineering

Aircraft convention defines the attitude parameters in terms of three angles: roll, pitch and heading. These angles are referenced to the local horizontal plane defined by gravity vector. Attitude information for aircraft is obtained by using spinning rotor or ring laser gyroscopes. These systems are very precise but they suffer from many problems such as high cost, large size and weight and the requirements for elaborate and intricate mechanical structure. These problems can be reduced by the exploitation of the micro machined technology. In this work, an attitude measuring system based on the ADXL202 accelerometer, the HMC2003 magnetic sensor and …

Conduction-Band Tight-Binding Description For Si Applied To P Donors, A. S. Martins, Timothy B. Boykin, Gerhard Klimeck, Belita Koiller

Other Nanotechnology Publications

A tight-binding parametrization for silicon, optimized to correctly reproduce effective masses as well as the reciprocal space positions of the conduction-band minima, is presented. The reliability of the proposed parametrization is assessed by performing systematic comparisons between the descriptions of donor impurities in Si using this parametrization and previously reported ones. The spectral decomposition of the donor wave function demonstrates the importance of incorporating full band effects for a reliable representation, and that an incomplete real space description results from a truncated reciprocal space expansion as proposed within the effective mass theory.
