Spacelab data management subsystem phase B study

The Spacelab data management system is described. The data management subsystem (DMS) integrates the avionics equipment into an operational system by providing the computations, logic, signal flow, and interfaces needed to effectively command, control, monitor, and check out the experiment and subsystem hardware. Also, the DMS collects/retrieves experiment data and other information by recording and by command of the data relay link to ground. The major elements of the DMS are the computer subsystem, data acquisition and distribution subsystem, controls and display subsystem, onboard checkout subsystem, and software. The results of the DMS portion of the Spacelab Phase B Concept Definition Study are analyzed

Systems cost/performance analysis (study 2.3). Volume 2: Systems cost/performance model

A methodology which was developed for balanced designing of spacecraft subsystems and interrelates cost, performance, safety, and schedule considerations was refined. The methodology consists of a two-step process: the first step is one of selecting all hardware designs which satisfy the given performance and safety requirements, the second step is one of estimating the cost and schedule required to design, build, and operate each spacecraft design. Using this methodology to develop a systems cost/performance model allows the user of such a model to establish specific designs and the related costs and schedule. The user is able to determine the sensitivity of design, costs, and schedules to changes in requirements. The resulting systems cost performance model is described and implemented as a digital computer program

Campus Rooftop Wind Energy Feasibility

This Interactive Qualifying Project (IQP) assessed the feasibility of installing a small roof-mounted wind power system(s) on the Worcester Polytechnic Institute (WPI) campus through wind data collection, survey assessment of community attitudes, the contact of manufacturers of potential wind power systems, and preparation of cost benefit analyses. A potential location for the wind power system(s) was selected, recommendations for an educational wind power system(s) and community involvement were made, and results were made available to the community

Index to 1985 NASA Tech Briefs, volume 10, numbers 1-4

Short announcements of new technology derived from the R&D activities of NASA are presented. These briefs emphasize information considered likely to be transferrable across industrial, regional, or disciplinary lines and are issued to encourage commercial application. This index for 1985 Tech Briefs contains abstracts and four indexes: subject, personal author, originating center, and Tech Brief Number. The following areas are covered: electronic components and circuits, electronic systems, physical sciences, materials, life sciences, mechanics, machinery, fabrication technology, and mathematics and information sciences

Solar Energy Guide

The goal of this project was to work with la Cámara de Industria de Costa Rica (CICR) to address high industrial energy prices by promoting photovoltaic systems for self- generation. Through interviews with solar providers, electricity distributors, and companies who have photovoltaic systems, information was gathered on the installation process, system pricing, providers of technology, and success cases. This information was organized into a guide, tailored to Costa Rican industries, that brings the reader step- by-step through the necessary considerations for implementing a photovoltaic system

ECE aspects of Zero Energy House

The goal of this MQP was to design and implement a photovoltaic (PV) system and Oasis; a stand-alone web-based bidirectional wattmeter to aid Team BEMANY of the Solar Decathlon China 2013 competition in meeting their goal in implementing a zero energy house. To achieve this goal, a wireless digital multimeter with an accuracy of 0.1% with a minimum wireless range of 10m was created to monitor the voltage of the individual panels of the PV array and it relayed the data to a microcontroller based server. This server would then communicate with a router to upload the data to a website. This website served as the graphic user interface for the entire system

Solar energy in buildings: Implications for California energy policy

An assessment of the potential of active solar energy systems for buildings in California is summarized. The technology used for solar heating, cooling, and water heating in buildings is discussed. The major California weather zones and the solar energy designs are described, as well as the sizing of solar energy systems and their performance. The cost of solar energy systems is given both at current prices and at prices consistent with optimistic estimates for the cost of collectors. The main institutional barriers to the wide spread use of solar energy are summarized
