A DSP embedded optical naviagtion systemGunnam, Kiran Kumar 30 September 2004 (has links)
Spacecraft missions such as spacecraft docking and formation flying require high precision relative position and attitude data. Although Global Positioining Systems can provide this capability near the earth, deep space missions require the use of alternative technologies. One such technology is the vision-based navigation (VISNAV) sensor system developed at Texas A&M University. VISNAV comprises an electro-optical sensor combined with light sources or beacons. This patented sensor has an analog detector in the focal plane with a rise time of a few microseconds. Accuracies better than one part in 2000 of the field of view have been obtained. This research presents a new approach involving simultaneous activation of beacons with frequency division multiplexing as part of the VISNAV sensor system. In addition, it discusses the synchronous demodulation process using digital heterodyning and decimating filter banks on a low-power fixed point DSP, which improves the accuracy of the sensor measurements and the reliability of the system. This research also presents an optimal and computationally efficient six-degree-of-freedom estimation algorithm using a new measurement model based on the attitude representation of Modified Rodrigues Parameters.

Polohování objektu ve 3D prostoru pomocí paralelního lanového robota / Object positioning in 3D space using parallel cable-driven robotRajnoha, Andrej January 2016 (has links)
At the beginning of this master’s thesis the definition of types of robots using parallel kinematics are presented, its possibilities of usage and current prototypes are described. The second chapter focuses on the proposal of robot construction and sizing electric and non-electric components of robot hardware. Derivation of direct and inverse transform mechanisms with creating flowcharts of their algorithms are stated in the two following chapters. The state machine controlled from user interface is then programmed based on these flowcharts. At the end of the work, cable-driven robot positioning accuracy is evaluated and platform workspace, together with motion and electric parameters, are measured.

Selection of industrial and organisational psychology master's students: exploring the validity of applied psychometric measuresOlivier, Karina Cornelia 10 1900 (has links)
The objective of this study was to investigate how well the academic performance of the
Industrial and Organisational Psychology master’s students at a research institution can be
predicted through psychometric measures. A non-experimental design was used in this
empirical study. The sample consisted of one hundred and thirty-three IO Psychology master’s
students over a five-year period.
The secondary data for this research originated from the students completing the Graduate
Verify Ability tests as well as the Occupational Personality Questionnaire, which are
psychometric measures that form part of the selection. Both psychometric measures load onto
the Person Job Match competencies. A theoretical relationship could be found between the
Ability tests and academic success as well as the PJM competencies that included weighted
scores from both psychometric measures. The empirical relationships, therefore, proved that
the ability tests have the strongest predictive ability for academic success. / Industrial and Organisational Psychology / M. Com. (Industrial and Organisational Psychology)

The application of affirmative action in employment law with specific reference to the beneficiaries: a comparative studyMcGregor, Marié 30 June 2005 (has links)
South African affirmative action law in the workplace is in its infancy. Yet some concepts in this context have already proven to be unclear or in need of interpretation, or are lacking.
This thesis focuses on the beneficiaries of affirmative action in employment law. The Employment Equity Act (EEA) creates `designated groups' ─ black people, women and people with disabilities ─ as the beneficiaries of affirmative action. It lays down two requirements for beneficiaries of affirmative action which are investigated: (a) beneficiaries must be from the designated groups - in this regard, the question that arises is whether, having been categorised as disadvantaged, persons are presumed to be de facto disadvantaged and entitled to benefit from affirmative action, or whether further evidence of actual past disadvantage is required; and (b) beneficiaries must be `suitably qualified'. In addition, citizenship as a third requirement for beneficiaries of affirmative action has been mooted in case law. This is evaluated against modern interpretation theory, the Constitution and discrimination law.
Against the background of a comparative investigation of the position in the US and Canada, and under international law, specific findings and recommendations are made in respect of South African affirmative action law. These relate to the interpretation of the concept `disadvantage', to a pragmatic and contextualised approach to the notion `degrees of disadvantage', to the recognition of the concept `multiple disadvantage', to the clarification of the meaning and application of the concept `suitably qualified' in a code of good practice, and to a policy decision by government to ensure that affirmative action measures apply mainly to South African citizens who otherwise qualify to benefit.
To this end, certain amendments to the EEA, its regulations and codes of good practice are proposed with the aim of ensuring that affirmative action measures in fact benefit those intended by the EEA.
Some projections are made to indicate the way forward for affirmative action in South Africa. / Jurisprudence / LL.D.
