The design, analysis and experimental evaluation of an elastic model wing

An elastic orbiter model was developed to evaluate the effectiveness of aeroelasticity computer programs. The elasticity properties were introduced by constructing beam-like straight wings for the wind tunnel model. A standard influence coefficient mathematical model was used to estimate aeroelastic effects analytically. In general good agreement was obtained between the empirical and analytical estimates of the deformed shape. However, in the static aeroelasticity case, it was found that the physical wing exhibited less bending and more twist than was predicted by theory

User's guide to program FLEXSTAB

A manual is presented for correctly submitting program runs in aerodynamics on the UNIVAC 1108 computer system. All major program modules are included. Control cards are documented for the user's convenience, and card parameters are included in order to provide some idea as to reasonable time estimates for the program modules

Greenhouse of the future. Final report

This greenhouse of the future is located at the Center for Regenerative Studies (CRS) at Cal Poly Pomona. The building design was driven by desired environmental conditions. The primary objective was to keep the interior space warm during winter for the breeding of fish and other greenhouse activities, especially in the winter. To do this, a highly insulating envelope was needed. Straw bales provide excellent insulation with an R-value of approximately 50 and also help solve the environmental problems associated with this agricultural waste product. A summary of the construction progress, construction costs and operating costs are included

Microsystems for Bioelectronics: the Nanomorphic Cell

This book considers physical principles and trends in extremely scaled autonomous microsystems for biomedical applications. It provides a physics-based assessment of the ultimate potential of miniaturization technologies. In particular, fundamental scaling limits for energy sources, sensors, computation and communication subsystems are developed. The book is comprised of seven chapters that examine various facets of semiconductor bioelectronic microsystems. The book targets a broad audience with engineering background and can also be useful for the biomedical community.Rapid advances in micro

The Matched Delay Technique: Theory and Practical Issues

Introduction Because of the advent of very high speed, optical fiber networks, and powerful microprocessors, there is a strong trend toward using a network of processors, rather than a single very expensive processor, for high performance computing. A fundamentally important component of this type of computing architecture is a low cost, high bandwidth network interface for each of the processors. GaAs or ECL technologies currently are used to implement high performance network interfaces. These circuit families have high cost and power consumption relative to CMOS. Also, CMOS has a much better ability to integrate higher level network functionality with the interface circuitry. So far, however, CMOS technologies have not been able to support network bit rates above 100 - 200 megabits per second. Specifically, the serializer/deserializer function is the performance bottleneck in a CMOS implementation of a network interface. Research into new circuit techniques are needed if th
