Computer program for the analysis of non-prismatic beamsAlas, Roberto Antonio 18 April 1989 (has links)
One of the major problems in the analysis of beams with Moment of Inertia varying along their length, is to find the Fixed End Moments, Stiffness, and Carry-Over Factors.
In order to determine Fixed End Moments, it is necessary to consider the non-prismatic member as integrated by a large number of small sections with constant Moment of Inertia, and to find the M/EI values for each individual section. This process takes a lot of time from Designers and Structural Engineers.
The object of this thesis is to design a computer program to simplify this repetitive process, obtaining rapidly and effectively the Final Moments and Shears in continuous non-prismatic Beams.
For this purpose the Column Analogy and the Moment Distribution Methods of Professor Hardy Cross have been utilized as the principles toward the methodical computer solutions.
The program has been specifically designed to analyze continuous beams of a maximum of four spans of any length, integrated by symmetrical members with rectangular cross sections and with rectilinear variation of the Moment of Inertia. Any load or combination of uniform and concentrated loads must be considered.
Finally sample problems will be solved with the new Computer Program and with traditional systems, to determine the accuracy and applicability of the Program.

A hardware emulator testbed for a software-defined radio.Witkowsky, Jason January 2003 (has links)
Submitted in fulfillment of the requirement for the
Masters degree of Technology (MTech): Electrical Engineering, 2003 / Contemporary software-defined radio (SDR) is continuously changing and challenging
the way traditional RF systems operate. Having more of a radio system’s operation in
software enables further flexibility through the use of software manipulation. Due to
practical limitations, however, it is not always feasible to have the entire radio system’s
operations performed using software. Practical limitations, therefore, require that a SDR
employs some form of RF front-end in order to interface the antenna signals and the
signals prior to the data converters.
As technology grows in support of SDR development, this hardware interface is becoming
increasingly smaller. The problem with the rapid rate at which SDR developments are
occurring is that RF hardware needs to change accordingly. Therefore, the RF hardware
front-end can be seen as a non-standardised piece of equipment. To the designer, this
means having to prototype in hardware in order to experiment with various types of SDR
hardware front-ends.
One of a SDR’s main attractions is the inherent property of software testability. Taking
this fact into account, this thesis investigates the design and operation of a basic softwaredriven
RF front-end emulator for a SDR. Basic prototype software models are identified
and developed in order to test their performance within the emulator. The focus of the
thesis, however, is geared toward the development of a software architecture that enables
a high degree of interchangeability amongst the underlying modelled components.
In the case of a SDR, the advantage of prototyping in software is in predicting the
behaviour of a system prior to having to perform any physical developments. This property
of software testability in the emulator can only fully be appreciated if a bench-mark
system is used to evaluate the overall performance of the emulator. Therefore, a physical
hardware setup is performed in order to test the basic aspects of the emulators operation.
This evaluation is not meant as an exhaustive analysis of the emulator, but aims to highlight
the overall performance of the emulated system against a typical physical system
setup.

Using virtual reality to monitor and control an industrial robot via the InternetVermeulen, Heinrich January 2001 (has links)
Manufacturing processes may be modeled in various ways, including 3D modeling. There is a need to visualise, control and monitor manufacturing processes remotely via the Internet. Virtual Reality (VR) can be described as the science of integrating man with information. It is based on three distinct environments: three-dimensional, interactive and computer-generated. VR has come to the Internet in the form of VR modeling. The evolution of Web technologies in recent years has enabled the use of VR modeling for visualisation of manufacturing processes. The VR modeling language (VRML), which has become the standard for transmitting 3D virtual worlds across the Internet, can be used to control and monitor manufacturing processes visually. A 3D model of a manufacturing process, specifically an industrial robot arm, was created for this project. This model was successfully linked to the industrial robot that it represents in order to control and monitor the robot’s actions remotely via the Internet using Web technologies. This dissertation proves the viablity of using Virtual Reality to effectively visualise, monitor and control an industrial robot via the Internet. It also describes the methodology that was followed in modeling the industrial robot arm in VRML as well as linking the model to the real world application.

On an implementation of abstract interpretationWestcott, Doug January 1988 (has links)
This thesis describes an implementation of abstract interpretation and its application to strictness analysis and termination analysis. The abstract interpretation is performed based on a lattice-theoretical model of abstraction, or translation, of functions expressed in a lambda-calculus notation and defined over a concrete domain into functions defined over a user-specified, application-dependent, abstract domain. The functions thus obtained are then analyzed in order to find their least fixed-points in the lattice which is the abstract domain, using a method which is a simplification of the frontiers algorithm of Chris Clack and Simon Peyton Jones. In order to achieve the required efficiency, this method is implemented using lattice annotation, along with constraints upon the annotations. The implementation is then applied to the problems of strictness analysis and termination analysis, deriving useful pre-compilation information for many functions. The concrete domains over which the functions are defined may or may not include lists. / Science, Faculty of / Computer Science, Department of / Graduate
