Submitted to the Faculty of Arts in fulfillment of the requirements for the degree of Doctor of Philosophy (D.Phil) in the Department of Communication Science at the University of Zululand, South Africa, 2004. / This dissertation focuses on the contribution of electronic communication (e-Communication) to knowledge management. It is based on an empirical survey of knowledge management practitioners in the private, public and NGO sectors in KwaZulu-Natal, South Africa. The major findings of this study are (1) that many knowledge management practitioners have not received any formal training in knowledge management, (2) that for most of them their practices are not informed by explicit knowledge management policies, (3) that there is no culture of sharing knowledge established within particular organisations, and finally (4) that knowledge managers are not using e-learning facilities to keep their knowledge of knowledge management current.

This research investigated whether the buyer-seller interorganizational relationship (IOR) differed between a firm and two classes of customers. The first class used electronic data interchange (EDI) with the firm and the second class used the traditional paper-based purchasing system. IOR characteristics included reputation, skill, direct power, indirect power, reciprocity, and efficiency.

The purpose of this dissertation is to explicate the meaning of information systems (IS) success in the realm of a dynamic hierarchical structure model of IS success. Through an empirical study of 382 firms using internal and Electronic Data Interchange (EDI) systems, different characteristics of this model are examined via four hypotheses. / First, using linear structural modelling techniques, it is shown that successful information systems share certain properties common to all systems, in addition to certain properties specific to each class of systems. Four generic factors influencing IS success are identified as (i) output reliability, (ii) system's characteristics, (iii) efficiency outcomes, and (iv) users' requirements. Second, the role of time in the IS adoption and assessment process is explored. By comparing firms that have adopted EDI with those that have not adopted EDI, it is shown that the decision maker's perception of IS success changes during different stages of the adoption and assessment process. Third, the role of stakeholders in the assessment process is examined by comparing perceptions of different managerial groups based on their educational background, management echelon, and functional area. It is shown that different stakeholders evaluate the success of IS differently. Finally, through an examination of various types of evaluation functions, it is shown that IS success is a multi-dimensional construct. / Overall, cross-group comparisons of the dynamic hierarchical structural model of IS success provide sufficient evidence regarding the instability of IS success across time, type of system, and stakeholders involved in the evaluation process. / In addition to the major hypotheses, two corollaries have also been examined. It is shown that user involvement in an IS project has a positive effect on the system's success. Further, the results of the study indicate that respondents in smaller companies are more satisfied with the support and services of the MIS department than their counterparts in larger companies. / Finally, by comparing three versions of the questionnaire used in the study, it is shown that question order has a significant effect on responses. The implications of this finding for survey studies are discussed.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Historically, different aspects of the configuration of an airborne instrumentation system were specified in a variety of different software applications. Instrumentation setup software handled the definition of measurements and PCM Formats while separate applications handled pre-flight checkout, calibration and post-flight data analysis. This led to the manual entry of the same data multiple times. Industry standards such as TMATS strive to address this problem by creating a data-interchange format for passing setup information from one application to another. However, a better alternative is to input all of the relevant setup information about the sensor and the measurement when it is initially created in the instrumentation vendor’s software. Furthermore, an additional performance enhancement can be achieved by adding the ability to perform sensor calibration and engineering unit conversions to pre-flight data visualization software that is tightly coupled with the instrumentation setup software. All of the setup information can then be transferred to the ground station for post-flight processing and data reduction. Detailed reports can also be generated for each measurement. This paper describes the flow of data through an integrated airborne instrumentation setup application that allows sensors and measurements to be defined, acquired, calibrated and converted from raw counts to engineering units. The process of performing a sensor calibration, configuring engineering unit conversions, and importing calibration and transducer data sheets will also be discussed.

Satellite communication promises potential methods for providing global communication. In particular, by the development of a Low Earth Orbital (LEO) satellite constellation, both global coverage and broadband communication will be accessible. Problems arise in situations where various traffic types in broadband communication require different levels of quality of service (QoS). Traffic control is required to make sure that each traffic demand may receive the expected QoS. Another problem is that the dynamic topology of a LEO satellite network requires a traffic allocation control, which is able to allocate traffic demand into the Inter Satellite Links (ISLs) between LEO satellites.In this thesis, traffic allocation strategy in a dynamic LEO satellite communication network is studied and analyzed. The delivery of Quality of Service (QoS) is an important objective. Traffic allocation control is performed in the LEO satellite constellation to provide a near optimal utilization of these ISLs. An alternative solution is proposed in this research, in which a combination of two algorithms will be used to allocate traffic in this dynamic satellite network. The first algorithm allocates traffic during small time intervals, based on an assumption that the topology is unchanged during these intervals. The second algorithm allocates traffic after topology updating has been accomplished. Traffic allocation respects some constraints including QoS (due to multiservice requirements), capacity constraints, traffic distribution, and availability constraints. Both theoretical and empirical studies have been undertaken to examine the performance of the proposed algorithm, denoted GALPEDA (Genetic Algorithm Linear Programming and Extended Dijkstra Algorithm). The proposed algorithm provides privileges to a class of high priority traffic, including benefits for traffic allocation of multiclass traffic in LEO satellite communication. It provides a novel traffic allocation mechanism to cope with the dynamic topology of a LEO satellite; moreover this algorithm distributes multiservice traffic evenly over the network. Simulations results are provided.
