    Solar Panel Cleaning Robot
    (University of Hawaii at Manoa, 2014-09-26) Yee, Christina ; Garmire, David ; Electrical Engineering
    The Solar Panel Cleanerbot is an electrical engineering junior and senior design project. The objective is to build a robot that can clean the solar panels on the roof of Holmes Hall in order to maintain optimal efficiency. While it will first be designed for use on the Holmes Hall panels, we want to create a robot that can be modified easily to fit different photovoltaic arrays so that it can be used on both commercial and residential arrays. With little to no technology currently available to clean solar panels efficiently, this project could have a tremendous impact on solar panel life and clean energy efficiency.

    Electric Power Interconnection of Five Islands of Hawaii
    (University of Hawaii at Manoa, 2014-01-15) Yoshida, Steven ; Electrical Engineering
    A high voltage direct current submarine interconnection of the islands of Hawaii, Maui, Lanai, Molokai, and Oahu appears to be a possible solution to Hawaii's growing need for more electrical power. Such an interconnection will distribute the power output of at least two large power plants to be built, one on Oahu and one on Hawaii. These two plants may be either nuclearly powered or geothermally powered, permitting large plant output to cover the state's entire load. An interconnection of this nature may prove to be economically feasible, as shown by previous submarine interconnections in other parts of the world. However, due to the extreme depth encountered in the Alenuihaha Channel between the islands of Maui and Hawaii, this interconnection will be far more difficult than any previous interconnection, and will require a specially designed cable.

    Optimization of Search Programs in a Given Population
    (University of Hawaii at Manoa, 2014-01-15) Yeh, Richard ; Chattopadhyay, Rahul ; Electrical Engineering
    This report discusses optimal methods of search for physical disabilities in a given population. The study was motivated by a practical problem connected with school-health programs. Although it is primarily directed to solution of this specific problem, the mathematical model developed and the method of solution can be extended to more general problems. Consider a program for detection (for effective treatment) of physical disorders (such as hearing disabilities) in school-age children. Evidently, this involves a repetitive search within the student body for individuals inflicted with the physical disabilities of concern. This repetitive search is called a Search Program. As a search program consists of many constituents, the optimization of such involves the finding of a proper mix of these constituents such that the search program is optimal in some sense.

    A Software Buffer-Control Unit for the Aloha System
    (University of Hawaii at Manoa, 2014-01-15) Yao, Anthony ; Abramson, Norman ; Electrical Engineering
    This paper describes an interactive use of the HP 2114B minicomputer as an Input/Output and storage device to replace the ALOHA SYSTEM Buffer-control unit. The proposed system will consist of the Hewlett Packard 2114B minicomputer, the program and two or more interface boards. The introduction offers a general view of THE ALOHA SYSTEM as a whole and lists the advantages of the proposed system. We will also discuss the ALOHA Buffer and the HP 2114B computer.

    A Design for a Computer Terminal
    (University of Hawaii at Manoa, 2014-01-15) Wong, William ; Electrical Engineering
    The purpose for this study is to redesign and build a cheap computer terminal--between $300 and $600 each--to be connected to the HP 2114 computer presently in use in Holmes hall. The original idea for the terminal was conceived of by Professor Vincent Nicholson. There is one original terminal which belongs to the Hewlett Packard company and by their permission is available here through Professor Nicholson. The essential features of this terminal remain the same as the one I have redesigned. The changes made will be evident in the following pages. Although the new model was to have been built, I have not yet received all the parts needed. As a result, this report is in some ways a building guide.
