Pro optimalizaci letových trajektorií ve velmi malé nadmorské výšce, terenní vlastnosti musí být zahrnuty velice přesne. Proto rychlá a efektivní evaluace terenních dat je velice důležitá vzhledem nato, že čas potrebný pro optimalizaci musí být co nejkratší. Navyše, na optimalizaci letové trajektorie se využívájí metody založené na výpočtu gradientu. Proto musí být aproximační funkce terenních dat spojitá do určitého stupne derivace. Velice nádejná metoda na aproximaci terenních dat je aplikace víceroměrných simplex polynomů. Cílem této práce je implementovat funkci, která vyhodnotí dané terenní data na určitých bodech spolu s gradientem pomocí vícerozměrných splajnů. Program by měl vyčíslit více bodů najednou a měl by pracovat v $n$-dimensionálním prostoru.

Communication seems to play a pivotal role in any high school classroom. But it was found those classes or certain individual students shy away from engaging in effective communication during natural science lessons in Swaziland. One of the directives in the Swaziland National Education Policy states that syllabuses for studies in Form 4 and 5 should enable learners to develop essential skills which include communication and language skills. This study then, on realising that there was a gap between what was stated in the Education Policy and what was actually the case in the natural science classrooms, sought for a solution that would encourage effective communication in natural sciences. Therefore, the main purpose of the study was to encourage active participation of high school students in natural science lessons. The main research question posed for this purpose was: Can student motivation enhance classroom discourse for the negotiation of science understanding? Five sub-questions emanated from the main research question: (a) How does classroom discourse relate to natural science understanding? (b) What effect does external motivation have on discourse during natural science lessons? (c) What is the effect of feedback during natural science learning? (d) How can feedback be enhanced in the natural science class? (e) Which teaching strategies improve interactions during natural science learning? The study is organised into five chapters. The first chapter summarises the whole study by giving the problem statement, research aim and objectives, definition of terms, as well as chapter divisions. Chapter two provides the background to the study through the discussion of education theories based on classroom discourse and motivation. The third chapter presents detailed information about the research design, methods of data collection and analysis, as well as a proposed method for motivating students. The fourth chapter presents the research results, analysis and discussion. The fifth and the final chapter presents research findings, concluding remarks drawn from the research findings, as well as recommendations for similar future research. The case study style uses a qualitative, descriptive and exploratory approach. The study concentrated on theories explaining learning and motivation. The sample comprised six purposefully selected students and their two physical science teachers. Data were collected using the standardised open-ended interview and non-participant lesson observation methods, and from documents. The data were collected in two phases, the pre-motivation phase and the motivation phase. The collected data was further categorised into two segments, with each segment being a unit of analysis. One of the segments was composed of oral interchanges, while the other was composed of students’ written work. The data was then transcribed, coded, analysed and discussed using the thematic discourse analysis approach. The principles of triangulation, reliability and validity ensured the credibility of the study remained intact. Research ethics were also observed by the researcher and there was trust, respect and autonomy during data collection. The ethics observed included informed consent, confidentiality, beneficence, anonymity and non-malificence. Permission to collect data was sought and obtained from all concerned. The motivation method helped the physics group improve more (55%) than the chemistry group (7%) in tests. In the overall performance the two groups improved more or less the same: the chemistry group improved by 4% while the physics group improved by 5%. There were three main findings for the study and they revolved around the purpose and the research question. The first major finding was that the motivation method used with the students instilled self-discipline in the students, resulting in self-regulated behaviour and better understanding of science concepts. The finding suggested that motivated students are self-disciplined and take ownership of their learning. The second major finding was that during the motivation phase of data collection interactions improved between the students and their science teachers. These interactions were in the form of classroom talk, submission of school work and feedback. It was inferred that motivated students communicate more effectively and with better understanding of the concepts taught. The third major revelation was that the students were motivated by learner-centred teaching strategies and the use of teaching aids in a science laboratory. A main finding for the first sub-question was that the more students interacted with each other, with their natural science teachers, and with their books the more they appreciated and understood science concepts. For the second sub-question the main finding was, the motivation method used with the students improved discourse during natural science lessons. The marks the students were awarded gave them the energy to engage more in science activities and to behave well. The main finding for the third sub-question was that prompt feedback and positive comments motivated students to engage more in science discourse and to understand science concepts better. An important finding from the fourth sub-question was that prompt and positive feedback enhanced feedback, as well as giving students tasks that were not too far above their abilities, enhanced feedback in the natural science class. For the fifth sub-question it was found that student-centred teaching methods as well as teaching aids and learning in science laboratories improved interactions during natural science learning. / Curriculum and Instructional Studies / D.

My master´s thesis deals with use of astronomical levelling for creation of quasigeoid models. The basic input dates are componets of astronomical-geodetic deflections of the vertical in points, which are determined on AGNES and VEVEŘÍ nets. The dates are adjust for determination of relative quasigeoid. In literature [4], there is simplified solution for adjustment of this dates. The thesis looks for the most comprehensive solutions of adjustment without simplification. The solutions are compared.

<p dir="ltr">Historically, CIOs have struggled to realize IT investment values and planning involved. In the IT industry, these issues have become a critical C-level topic (Haffke, 2016). Since the establishment of the position of the State Chief Information Officer (CIO), CIO roles have expanded and evolved tremendously as new modern technologies became a part of organization’s information technology (IT) enterprise infrastructure. Multiple State CIOs struggled with modern IT technologies, but successfully completed projects to meet customer business needs and requirements and furthermore, IT investments involved an arduous effort to prepare, execute, complete, and assess for return on investment (ROI) and value realization (NASCIO, 2021). During the COVID-19 pandemic, implementation of remote collaboration technology allowed the workforce to perform at remote locations to prevent spread of the virus. Academic research on the topic of State CIO’s involvement in IT strategic planning is limited and yields scarce search results compared to other subject areas. State CIOs’ involvement in IT strategic planning was further researched for enabling remote collaboration for the new remote workforce. Scholarly databases and more than 100 various sources of articles were reviewed for search results that addressed the problem and purpose of this research.<b> </b>Grounded theory research, data triangulation, and Computer-Assisted Qualitative Data Analysis software (CAQDAS) were used to analyze the resulting articles. The research deliverables included a document analysis of State CIO involvement in IT strategic planning to enable remote collaboration. There were significant involvements of State CIOs in IT strategic planning to enable remote collaboration during the COVID-19 pandemic across the analyses. This study developed a course of actions (COAs) for State CIOs, and recommendations for future research.</p>

In search of, the current and urgent, accompanied with our guiltless but potentially not agencies, we fight for the intelligence of reality. A zeitgeist that we try to ghostbust, that we hope to understand. A pandemonium circulated around the event, the now, the branches of time that flicker the possibilities and variations of expressions, that we as trajectories might solidify into a reality.  "So, one can start from a simple question, at which one does not care to conclude  with an answer: "why do we mark/trace a surface? Or for that matter, sculpt, think,  animate etc." What is the inclination behind it? And more importantly, why do we  cling to a specific preference?" In this essay I attempt a brief brush through from a number of familiar questions about art. And attempt to provide my own understanding, of art, creativity, society, and the ever newer intentions of the human expressive trajectories, that provide variations of possibilities and potentialities.

This study investigated the psychological approach and the classroom methodology needed by an educator to teach street children effectively in a special school created for them. Street children with their psychological trauma, their independent, self-sufficient outlook and educational deprivation make their adaption to the methods and educational environment of mainstream schooling difficult. To meet the special educational, psychological and emotional needs of street children, Masupatsela School was started. The study was carried out in this school. The qualitative research methodology used an action research design which consisted of a reconnaissance phase and three cycles. Each cycle made use of a planning, implementation and evaluation phase. A general plan was formulated after the reconnaissance phase and revised after each cycle. The teaching was done by the researcher using four grades of street children ranging form grade 7 to grade 10. Because of their specific psychological makeup, street children, who have lacked close, comforting and trusting relationships and role models, require a classroom environment, atmosphere and a relationship with the educator which is supportive, caring, warm and firm. To achieve this a client centred approach was used based predominantly on the therapeutic principles of congruence, empathetic understanding and unconditional positive regard. The interaction with the children was based on openness, tolerance, the affirmation of others and honest firmness. The teaching methodology was an eclectic one which made use primarily of a cognitive teaching style which was introduced incrementally over the three cycles. The main components of this style consisted of cognitive questioning, cooperative learning and strategic reading for information. The results of the study showed that both the psychological and educational approach in the classroom to be very appropriate and successful. However the wider negative contextual influences such as the school organization, staffing and curriculum made the classroom strategies difficult to sustain. It is recommended that a programme using these educational and psychological approaches and incorporating functional literacy and numeracy, vocational skills, recreation and a therapeutic programme be incorporated when designing a programme for street children in a formal setting. / Psychology / D.

In this thesis, I explore the impact and effectiveness of clinical supervision provided by external clinical supervisors, on workers from a variety of practice backgrounds in a residential rehabilitation centre, in the AOD sector. This thesis uses the framework of social work supervision, as defined by Kadushin (1985; 2002), with the administrative, educative and supportive elements. The research focuses closely on the latter two elements. For this purpose, I employ qualitative research methods, via a triangulation of methods, being guided by Participatory Action Research (PAR) and then conducting semi-structured interviews and focus groups as well as acting as a participant observer, to gather the data. The data was analysed using grounded theory. This research was based upon a clinical supervision project that was fully funded and provided free clinical supervision by external supervisors, providing both individual and group supervision, for a period of 10 months. There were a total of 16 respondents with varied roles and training backgrounds as well as an additional six supervisors, interviewed throughout different stages of the project. The various roles undertaken by me throughout the research process provided essential viewpoints on supervision, as well as the place of boundaries and need for support. The power of such a large scale intervention is discussed and ultimately highlights and identifies the particular benefits of supervision in this research arena. This thesis places clinical supervision in the context of workforce development in the Alcohol and Other Drug (AOD) sector. Thus, while this research elucidates a number of benefits and the factors involved with this experience, the clear separation of other modalities such as training, mentoring and Critical Incident debriefing are seen as integral additional avenues of support and professional development. This research concludes also with what the difficulties and hindrances were for people to continue with regular ongoing clinical supervision, and warrants the argument for interminable supervision in this setting. This research points to an overall paucity of literature on efficacy studies, especially in the AOD context in Australia. This research significantly adds to this dearth and examines the factors unique to the AOD sector in Australia, as well as what factors make for effective supervision. The particular impact of external supervisors and group supervision are explored, which underwrites the forwarded concept of a customised supervision for this setting. By making explicit in this research what the efficacy is on those new to supervision, it provides greater clarity for future studies. A number of recommendations are proposed as result of this research. New definitions of the supportive function of supervision and of clinical supervision are forwarded, as is a new look at the evolving history of social work supervision. This thesis highlights the impact of external supervisors and the unique contribution they offer.

The focus of this thesis is on facial biometrics; specifically in the problems of face detection and face recognition. Despite intensive research over the last 20 years, the technology is not foolproof, which is why we do not see use of face recognition systems in critical sectors such as banking. In this thesis, we focus on three sub-problems in these two areas of research. Firstly, we propose methods to improve the speed-accuracy trade-off of the state-of-the-art face detector. Secondly, we consider a problem that is often ignored in the literature: to decrease the training time of the detectors. We propose two techniques to this end. Thirdly, we present a detailed large-scale study on self-updating face recognition systems in an attempt to answer if continuously changing facial appearance can be learnt automatically. / L'objectiu d'aquesta tesi és sobre biometria facial, específicament en els problemes de detecció de rostres i reconeixement facial. Malgrat la intensa recerca durant els últims 20 anys, la tecnologia no és infalible, de manera que no veiem l'ús dels sistemes de reconeixement de rostres en sectors crítics com la banca. En aquesta tesi, ens centrem en tres sub-problemes en aquestes dues àrees de recerca. En primer lloc, es proposa mètodes per millorar l'equilibri entre la precisió i la velocitat del detector de cares d'última generació. En segon lloc, considerem un problema que sovint s'ignora en la literatura: disminuir el temps de formació dels detectors. Es proposen dues tècniques per a aquest fi. En tercer lloc, es presenta un estudi detallat a gran escala sobre l'auto-actualització dels sistemes de reconeixement facial en un intent de respondre si el canvi constant de l'aparença facial es pot aprendre de forma automàtica.
