Internal Organizational Communication During Crisis Situations: The Effect Of Supportive Messages On Employee Stress Levels, Carin L. Kosmoski Jan 2004

Internal Organizational Communication During Crisis Situations: The Effect Of Supportive Messages On Employee Stress Levels, Carin L. Kosmoski

Theses

This study investigates the effects of supportive messages from immediate supervisors or CEO's on employees during crisis situations. Supportive messages are hypothesized to decrease the stress levels of employees. The extent to which supportive messages from managers or executives during crisis situations affect employee perceptions of support from their organization, their CEO, and their immediate supervisor is also explored. During the research process, 78 volunteer participants received one of three messages from a hypothetical organization following a hypothetical crisis situation. Spearman's ranked correlations comparing reported support with reported stress levels indicate that, for the group studied, there is a negative …

Development Of A Human Visual System With The Ability To Detect Inconsistent Events, Jeremiah D. Brazeau Jan 2004

Development Of A Human Visual System With The Ability To Detect Inconsistent Events, Jeremiah D. Brazeau

Theses

Current research has shown that it is possible to create a general purpose learning system that models the first few layers of the human visual system. The goal of this thesis is to build upon that idea and produce a computational model capable of learning different aspects of visual information. Simulations show that the system is capable of learning and distinguishing different types of motion. Results also give one explanation, consistent with current experiments, explaining how the human visual system learns information and as such may produce the capability to predict behavior in future experiments.

Anatomy Of A Chaotic Attractor: Subtle Model-Predicted Patterns Revealed In Population Data, Aaron A. King, R. F. Costantino, J. M. Cushing, Shandelle M. Henson, Robert A. Desharnais, Brian Dennis Jan 2004

Anatomy Of A Chaotic Attractor: Subtle Model-Predicted Patterns Revealed In Population Data, Aaron A. King, R. F. Costantino, J. M. Cushing, Shandelle M. Henson, Robert A. Desharnais, Brian Dennis

Faculty Publications

Mathematically, chaotic dynamics are not devoid of order but display episodes of near-cyclic temporal patterns. This is illustrated, in interesting ways, in the case of chaotic biological populations. Despite the individual nature of organisms and the noisy nature of biological time series, subtle temporal patterns have been detected. By using data drawn from chaotic insect populations, we show quantitatively that chaos manifests itself as a tapestry of identifiable and predictable patterns woven together by stochasticity. We show too that the mixture of patterns an experimentalist can expect to see depends on the scale of the system under study.

Data Hiding In Images Based On Fractal Modulation And Diversity Combining, Sarat B. Atluri Jan 2004

Data Hiding In Images Based On Fractal Modulation And Diversity Combining, Sarat B. Atluri

Theses

The current work provides a new data-embedding infrastructure based on fractal modulation. The embedding problem is tackled from a communications point of view. The data to be embedded becomes the signal to be transmitted through a watermark channel. The channel could be the image itself or some manipulation of the image. The image self noise and noise due to attacks are the two sources of noise in this paradigm. At the receiver, the image self noise has to be suppressed, while noise due to the attacks may sometimes be predicted and inverted. The concepts of fractal modulation and deterministic self-similar …

Using System Call Analysis To Stop Evasion Attacks In Anomaly Based Intrusion Detection System, Ashish Liladhar Samant Jan 2004

Using System Call Analysis To Stop Evasion Attacks In Anomaly Based Intrusion Detection System, Ashish Liladhar Samant

Theses

Intrusion Detection Systems (IDSs) that operate on the principle of system call monitoring are known to be susceptible to mimicry or evasion attacks. It has been shown that an intelligent adversary armed with comprehensive knowledge of the target system or network, can penetrate these targets, hide his presence from the IDS, and continue to carry out damage. IDSs, which use system calls to define normal behavior, often leave out complimentary information about them, and intruders use precisely this drawback, to deceive the IDS. This thesis investigates the vulnerabilities of a system call based IDS and carries out a theoretical and …

Digitally Tunable Low Noise Amplifier, Mohamed Benmansour Jan 2004

Digitally Tunable Low Noise Amplifier, Mohamed Benmansour

Theses

Low noise amplifiers are classified into two categories: Wideband low noise amplifiers and Narrowband low noise amplifiers. Wideband LNAs are known for achieving a poor noise performance. On the other hand, the noise performance of the narrowband amplifiers is good but only over a small frequency range. This constraint made their use restricted to certain applications, such as cellular phone applications (superheterodyne architecture), where a single operational frequency is needed. This thesis introduces a new low noise amplifier topology that provides a high selectivity and a low noise figure over a wide frequency range. The digitally tunable low noise amplifier …

Dynamic Input Match Correction In R.F. Low Noise Amplifiers, Tejasvi Das Jan 2004

Dynamic Input Match Correction In R.F. Low Noise Amplifiers, Tejasvi Das

Theses

An R.F. circuit that recognizes its faults, and then corrects its performance in real-time has been the holy-grail of RFIC design. This work presents, for the first time, a complete architecture and successful implementation of such a circuit. It is the first step towards the grand vision of fault-free, package independent, integrated R.F. Front End circuitry. The performance of R.F. front-end circuitry can degrade significantly due to process faults and parasitic package inductances at its input. These inductances have wide tolerances and are difficult to co-design for. A novel methodology, which overcomes current obstacles plaguing such an objective, is proposed …

Teaching Twice Exceptional Children: Gifted With Learning Difficulties: Professional Development And Provision In A Montessori School, Elaine Lewis Jan 2004

Teaching Twice Exceptional Children: Gifted With Learning Difficulties: Professional Development And Provision In A Montessori School, Elaine Lewis

Theses: Doctorates and Masters

This study seeks to investigate the teaching of gifted children in a Montessori school, with particular reference to gifted students with learning difficulties in writing. A review of the literature on the Montessori method of education and on provision for gifted children, shows considerable philosophical and practical overlap in these two fields. However, it appears that this theoretical overlap is not necessarily realised in practice. Furthermore, although considerable research has been conducted on the characteristics, identification and classroom provision for the gifted, very little has been undertaken on the actual provision for gifted children in Montessori schools or gifted children …

Can B2g Portals Be Used Effectively To Stimulate Business In Smes?: A Case Analysis Of The 2cities Business To Government Portal, Ian Martinus

Theses: Doctorates and Masters

Small and Medium Enterprises (SMEs) have many options when purchasing goods or services. These include personal contacts and networks, familiar centralised supply sources and other ad hoc means. One purchasing possibility is to buy from and sell to other businesses within a similar geographic area. The benefits of buying and selling locally may not occur to SMEs. They seek, like other consumers, to get value for money, fast and efficient service, and a reasonable level of quality. Many factors can impinge upon an SME's decision to purchase locally. It can be assumed that, given a reasonable local option, SMEs wish …

Opto-Vlsi Based Wdm Multifunction Device, Selam T. Ahderom Jan 2004

Opto-Vlsi Based Wdm Multifunction Device, Selam T. Ahderom

Theses: Doctorates and Masters

The tremendous expansion of telecommunication services in the past decade, in part due to the growth of the Internet, has made the development of high-bandwidth optical net-works a focus of research interest. The implementation of Dense-Wavelength Division Multiplexing (DWDM) optical fiber transmission systems has the potential to meet this demand. However, crucial components of DWDM networks – add/drop multiplexers, filters, gain equalizers as well as interconnects between optical channels – are currently not implemented as dynamically reconfigurable devices. Electronic cross-connects, the traditional solution to the reconfigurable optical networks, are increasingly not feasible due to the rapidly increasing bandwidth of the …

Implementation Of Arithmetic Primitives Using Truly Deep Submicron Technology (Tdst), Sholeh Eshraghian

Theses: Doctorates and Masters

The invention of the transistor in 1947 at Bell Laboratories revolutionised the electronics industry and created a powerful platform for emergence of new industries. The quest to increase the number of devices per chip over the last four decades has resulted in rapid transition from Small-Scale-Integration (SSI) and Large-Scale-lntegration (LSI), through to the Very-Large-Scale-Integration (VLSI) technologies, incorporating approximately 10 to 100 million devices per chip. The next phase in this evolution is the Ultra-Large-Scale-Integration (ULSI) aiming to realise new application domains currently not accessible to CMOS technology. Although technology is continuously evolving to produce smaller systems with minimised power dissipation, …
