Semantic Correlation Of Behavior For The Interoperability Of Heterogeneous Simulations, Christopher James Dean Jan 1996

Semantic Correlation Of Behavior For The Interoperability Of Heterogeneous Simulations, Christopher James Dean

Retrospective Theses and Dissertations

A desirable goal of military simulation training is to provide large scale or joint exercises to train personnel at higher echelons. To help meet this goal, many of the lower echelon combatants must consist of computer generated forces with some of these echelons composed of units from different simulations. The object of the research described is to correlate the behaviors of entities in different simulations so that they can interoperate with one another to support simulation training. Specific source behaviors can be translated to a form in terms of general behaviors which can then be correlated to any desired specific ...

Simulator For The Performance Analysis Of Cpm Schemes In An Indoor Wireless Environment, Ronald Chua Jan 1996

Simulator For The Performance Analysis Of Cpm Schemes In An Indoor Wireless Environment, Ronald Chua

Theses : Honours

A software simulator for characterising Continuous Phase Modulation (CPM) schemes in an indoor multipath environment has been developed using SIMULINK and MATLAB. The simulator is capable of simulating a wide range of CPM schemes to determine bandwidth efficiency and robustness to additive white Gaussian noise (AWGN) and Rician fading. Initial trials of the simulator indicate that the simulator is functioning correctly. Eventually, the simulator will be used to determine the most suitable modulation scheme for the development of an actual indoor wireless system.


Analysis Of Background Noise For Wireless Microwave Lan Channels, Jason C. Hislop Jan 1996

Analysis Of Background Noise For Wireless Microwave Lan Channels, Jason C. Hislop

Theses : Honours

Perusal of the details within, should provide the reader with an insight into general wireless indoor communications within the microwave spectrum, with respect to the problems laced, specific to noise corruption of the transmitted signal. Indoor communication systems are difficult to model, due to the largely random nature of the relevant environment, and the compounding factors that degrade system performance. These factors are many and varied, in accordance with the operational topologies of possible application area. However, there exists a common and increasing need to effectively model the communication links in question. Part of this strategy involves having an understanding ...


Automation Of Real-Time X-Ray Scans, Madhusudhan R. Midhe Jan 1996

Automation Of Real-Time X-Ray Scans, Madhusudhan R. Midhe

Retrospective Theses and Dissertations

The present day needs of the commercial market have forced the industry to manufacture materials which are stronger, weigh less and cost less. In other words, it is of prime concern to characterize the material properties. The characterization of a material can be done either at the time of fabrication or while the material is being used. A material can be tested in two ways, destructively or non-destructively. In destructive means of testing materials, a sample is selected randomly from a batch and is inspected thoroughly and the results are extrapolated in a manner so that they represent the whole ...

Terminal Sliding Mode Control For Rigid Robotic Manipulators With Uncertain Dynamics, Nicola Ritter Jan 1996

Terminal Sliding Mode Control For Rigid Robotic Manipulators With Uncertain Dynamics, Nicola Ritter

Theses: Doctorates and Masters

This thesis presents two new adaptive control laws that use the terminal sliding mode technique for the tracking problem of rigid robotic manipulators with non-linearities, dynamic couplings and uncertain parameters. The first law provides a robust scheme which uses several properties of rigid robotic mauipulators and adaptively adjusts seven uncertain parameter bounds. The law ensures finite time error convergence to the system origin and is simple to implement The second law treats the manipulator as a partially known system. The known dynamics are used to build a nominal control law and the effects of unknown system dynamics arc compensated for ...


Development Of A Pulsed Eddy Current Instrument For Corrosion Detection, Sunil K. Shaligram Jan 1996

Development Of A Pulsed Eddy Current Instrument For Corrosion Detection, Sunil K. Shaligram

Retrospective Theses and Dissertations

The pulsed eddy current technique has been under development at Iowa State University since 199:3 under the supervision of Mr. John Moulder. It has shown much promise for detecting corrosion and cracks in multi-layered aircraft structures, and has elicited strong interest from the aviation community. The Pulsed Eddy Current Group at the Center for Nondestructive Evaluation, ISU, has built an instrument which utilizes the theory behind pulsed eddy currents and transforms it into a practical field instrument.


The Mobile Telephone: The Transportation Of Social Relationships, Kenneth C. Staples Jan 1996

The Mobile Telephone: The Transportation Of Social Relationships, Kenneth C. Staples

Theses: Doctorates and Masters

In the studies of contemporary electronic media artifacts and their effects on society, television, satellites, and computers have been extensively investigated and their various impacts well documented. With regards to telecommunication technologies, academic scholarship is somewhat less, with most comment being restricted to either historic evolution, or technical description. Exceptions to this are, Marvin's reference to the telephone in her publication, When Old Technologies Were New: Thinking About Electronic Communication in the Late Nineteenth Century (1988}, and Umble's The Amish and the telephone: resistance and reconstruction (1992). Both of these publications are used for supporting arguments in my ...
