Generally  cameras  are  used  for  area  based  surveillance,  but  with  advancement  in  technology, cameras  can  be  employed  for wide  area  space  surveillance  (volumetric space surveillance). The volumetric systems require a number of cameras in order to cover a large area. Single panoramic cameras  do  not  provide  required  functionality  for  wide  area  space  surveillance  and Pan-Tile-Zoom (PTZ) cameras do not either cover wide areas.   To  meet  this challenge,  we  propose  a  cost  effective smart volumetric  surveillance system  which utilizes smaller number of cameras in order to provide a coverage of 360 degree. A test case used for this system includes detection of birds in the wind farms. The proposed approach provides a solution  for recording/preventing collision  of  birds  with  wind turbine. To  realize  the  system, a model is developed with two camera nodes. This model provides a 360 degree conical volumetric space coverage. The  system is  utilizing  a  servo  motor  with  capability  of  changing  speed  and arduino  embedded  platform for  controlling  different  functionality. After  triggering  the  camera nodes from arduino, software perform the image analysis.  This  cost  effective  and  wide  area  surveillance  system  consumes at  least half lower  power as compared  to traditional  linear  systems with  eight  cameras. It  is  worth  noting  that  the system provides  conical  shaped  area coverage  of  200  square  meters  with  height ranging  from approximately 40 to 100 meters. The system would capture images in raw format in local storage and  the test  results  show  that  saving  images  with  PNG  format  requires a small  memory  size  as compared  to BMP  and TIFF.    Experiment  results  indicate  that  surveillance  system  can  be effectively employed for detecting birds in opening places.

The purpose of this study is to investigate the influence of administrative duties on effective classroom management in the Further Education and Training phase in the Sedibeng West District (08) of the Gauteng Province by focusing on classroom management; management skills of professional teachers; the relationship between teaching and management; guidelines for effective classroom management; juridical aspects regarding classroom management; workload of school-based teachers; duties and responsibilities of teachers; impact of workload of school-based teachers; educational policies; other policies and factors impacting on teachers' workload; and factors that drive teachers away from teaching. The literature study reveals that administrative duties take up a great deal of teachers' time. This is due to a number of factors, namely: shortages of teachers and high learner numbers; departmental accountability measures such as the Integrated Quality Management System (IQMS); curriculum and assessment requirements; and the lack of basic resources. Stress regarding classroom administration exacerbates because teachers have to perform a variety of tasks, from secretarial and administrative to curricular, extracurricular and pastoral work. A major finding emanating from the research is that teachers should be released from excessive amounts of administrative duties and other activities that increase their workload and distract their focus from teaching. In order to eliminate these excessive amounts of administrative duties, the Department of Education should, through proper planning and cooperation with the School Management Team (SMT) provide extra posts in schools for administrators who can assist teachers. The empirical study consists of a structured questionnaire distributed to a sample of principals, deputy principals, heads of departments and teachers in schools in the Sedibeng West District (08) of the Gauteng Province. It aims to develop guidelines to assist teachers to cope better with the increased administrative demands. The main findings of the study reveal that most teachers have difficulties in coping with the pace at which the Whole School Evaluation Policy, IQMS, Continuous Assessment Policy and the new curriculum are being implemented. Together with the increased amount of administrative duties, an urgent need exists for support from the Department of Education and the District Office regarding the implementation and the alleviation of administrative demands. This study recommends, on the basis of both the literature review and the empirical research, guidelines to assist all teachers in coping with these increased administrative demands effectively. / Thesis (M.Ed.

We present two re-derivations of the Scharnhorst effect. The latter was first obtained in 1990 by Klaus Scharnhorst, soon followed by Gabriel Barton, and consists in the theoretical prediction that the phase velocity of photons propagating in a Casimir vacuum normal to the plates would be larger than c. The first derivation given in the present work is relevant for the debates that have taken place in the physics literature regarding a possible greater-than-c value of the signal velocity. Indeed because the phase velocity result also held for the group velocity, the issue soon arose as to whether the same could be said for the signal velocity. Several arguments were presented against this notion, notably to the effect that measurement uncertainties would preclude such a measurement. These notably relied on the fact that the known phase velocity result is only valid within a certain frequency regime. Scharnhorst and Barton responded by arguing that given their previous result, the Kramers-Kronig relations imply one of two options: either the greater-than-c result holds for the signal velocity as well, or the Casimir vacuum behaves like an amplifying medium for some frequencies. Furthermore, the effect was later rederived and generalized within the framework of an effective metric approach, which has been argued to obviate the worries regarding causal paradoxes often associated with the possibility of faster-than-c signalling. However concerns related to theory errors as well as to the measurement uncertainties that had surfaced in the earlier debate have remained salient. By re-deriving the phase velocity using Soft-Collinear Effective Theory (SCET), one can address some of these concerns. Indeed, with regard to theory errors, SCET provides us with a framework where higher order corrections are known to be power-suppressed because SCET ensures that the expansion parameters are multiplied by factors of order 1. As a result, with due qualifications inherent to the nature of effective field theory, the result obtained within the SCET approach cannot be invalidated by higher order corrections. Furthermore, the theoretical description offered by SCET provides an argument relevant to the point that measurement uncertainties would prevent measuring the signal speed to be faster-than-c. Indeed, SCET implies the interaction between the Casimir vacuum and the propagating photon to be such that the latter would have the same phase velocity irrespective of its frequency. This in turn would entail that its signal velocity would be equal to this phase velocity, which is faster-than-c. The second calculation presented is concerned with the physical interpretation of the Scharnhorst effect, and constitutes an attempt at re-deriving it within source theory. Existing derivations imply that the Scharnhorst effect can be attributed to vacuum fluctuations. Other physical effects that share this feature have also been derived without any reference to the vacuum, but as due to source fields instead. We attempt a similar derivation for the Scharnhorst effect.

Following Barr and Tagg's formalization of the concept of learner-centered educational practice at the postsecondary level as described in their seminal article in Change in 1995, survey instruments have been developed to assess teachers' beliefs about their own learner-centeredness.. The research reported in this dissertation examined the connection between college students' perceptions of teacher effectiveness on each of four dimensions appearing as questions on the IDEA Survey of student reaction to instruction and courses (developed at the IDEA Center, Kansas State University, in the early 1970s) and the Assessment of Learner-Centered Practices (ALCP): Beliefs Portion of the Postsecondary Level Instructor Survey, College Level (developed in early 1999 by B. L. McCombs, University of Denver Research Institute; alpha reliabilities reported). Using scoring rubrics accompanying the ALCP instrument, instructors were identified as learner-centered or non-learner-centered based on their responses. Independent t-tests were performed to determine whether learner-centered instructors were perceived differently by students in terms of teaching effectiveness than non-learner-centered instructors on each of four dimensions: overall excellence of course, overall excellence of instructor, effectiveness of instructor in helping students achieve relevant objectives in the course, and effectiveness of course and instructor in improving students' attitude toward the field of study. Students rated learner-centered instructors higher in all dimensions, but results were not statistically significant. Instructors were also identified as possessing learner- or non-learner-centered beliefs to a greater degree than that necessary for an overall designation. Independent t-tests were performed to determine any differences in student perceptions of effectiveness between these two groups. Again, students rated learner-centered instructors higher in all dimensions, but results were not statistically significant. Recommendations for further research with the ALCP instrument are made, including research to determine whether specific factors and/or questions prove to be statistically significant in predicting student evaluations of effectiveness. Also recommended are replications of the study to investigate moderating variables influencing accurate faculty self-identification of beliefs about teaching and learning.

The topic of this diploma work is "Effective repentance and bribery". Effective repentance is a reason which causes an extinction of punish ability. There are two kinds of effective repentance. The first is a general effective repentance. The second is a specific effective repentance. General effective repentance causes impunity when offender of criminal act of listed crimes retrieved injury by his own will, or announced criminal act to prosecutor or police officer in time when should be injury retrieve. Specific effective repentance is codified for just a few crimes. One of these crimes, where specific effective repentance was codified is bribery. Bribery effective repentance means, that the offender of bribe giving will not be penal responsible if he gives or promises bribe, just because he was asked for bribe and if he (by his own will and immediately) announced this to a prosecutor or a police officer. In the past since 1950 we have had this specific repentance in criminal law. Since 1/1/2010 we have got a new criminal law no 40/2009 Sb. New codex no. 40/2009 Sb. despite original legislative proposal does not codify specific effective repentance in corruption cases. It was tried to describe historical aspects of effective repentance in context with development of criminal law in our country. In my...

Master of Music / School of Music, Theater, and Dance / Julie Yu-Oppenheim / This report is for the beginning choral music educator or music education student who seeks guidance when selecting repertoire for their advanced elementary or beginning middle school choir. I attended the 2011 Kansas Choral Directors Association conference. Conferences such as these are great resources for the novice choral educator and even the veteran teacher. Choral reading sessions are excellent ways to find new and quality repertoire, because the directors that select the music spend a good amount of time researching and selecting songs. In determining what factors directors use to choose repertoire for their choirs, a survey was developed and administered to forty Kansas music educators at one of the reading sessions which asked the following three questions: 1) What is the likelihood that you would use this song in a concert or program? The next two are questions in which I asked (these two were based on a ‘disagree or agree’ scale): ‘This song has good educational value for the students’ and ‘I can teach many elements of music within this song.’ Evidence is shown from other master educators of various levels that choosing appropriate, worthy, and challenging repertoire is crucial to the success of the choral program.

Doctor of Philosophy / Department of Civil Engineering / Sunanda Dissanayake / Malgorzata J. Rys / Driver workload increases on horizontal curves due to more complicated navigation compared to navigation on straight roadway sections. Although only a small portion of roadways are horizontal curve sections, approximately 25% of all fatal highway crashes occur at horizontal curve sections. According to the Fatality Analysis Reporting System (FARS) database, fatalities associated with horizontal curves were more than 25% during last years from 2008 to 2014, reinforcing that investigation of horizontal curve crashes and corresponding safety improvements are crucial study topics within the field of transportation safety. Improved safety of horizontal curve sections of rural transportation networks can contribute to reduced crash severities and frequencies. Statistical methods can be utilized to develop crash prediction models in order to estimate crashes at horizontal curves and identify contributing factors to crash occurrences, thereby correlating to the primary objectives of this research project. Primary data analysis for 221 randomly selected horizontal curves on undivided two-lane two-way highways with Poisson regression method revealed that annual average daily traffic (AADT), heavy vehicle percentage, degree of curvature, and difference between posted and advisory speeds affect crash occurrence at horizontal curves. The data, however, were relatively overdispersed, so the negative binomial (NB) regression method was utilized. Results indicated that AADT, heavy vehicle percentage, degree of curvature, and long tangent length significantly affect crash occurrence at horizontal curve sections. A new dataset consisted of geometric and traffic data of 5,334 horizontal curves on the entire state transportation network including undivided and divided highways provided by Kansas Department of Transportation (KDOT) Traffic Safety Section as well as crash data from the Kansas Crash and Analysis Reporting System (KCARS) database were used to analyze the single vehicle (SV) crashes. An R software package was used to write a code and combine required information from aforementioned databases and create the dataset for 5,334 horizontal curves on the entire state transportation network. Eighty percent of crashes including 4,267 horizontal curves were randomly selected for data analysis and remaining 20% horizontal curves (1,067 curves) were used for data validation. Since the results of the Poisson regression model showed overdispersion of crash data and many horizontal curves had zero crashes during the study period from 2010 to 2014, NB, zero-inflated Poisson (ZIP), and zero-inflated negative binomial (ZINB) methods were used for data analysis. Total number of crashes and severe crashes were analyzed with the selected methods. Results of data analysis revealed that AADT, heavy vehicle percentage, curve length, degree of curvature, posted speed, difference between posted and advisory speed, and international roughness index influenced single vehicle crashes at 4,267 randomly selected horizontal curves for data analysis. Also, AADT, degree of curvature, heavy vehicle percentage, posted speed, being a divided roadway, difference between posted and advisory speeds, and shoulder width significantly influenced severe crash occurrence at selected horizontal curves. The goodness-of-fit criteria showed that the ZINB model more accurately predicted crash numbers for all crash groups at the selected horizontal curve sections. A total of 1,067 horizontal curves were used for data validation, and the observed and predicted crashes were compared for all crash groups and data analysis methods. Results of data validation showed that ZINB models for total crashes and severe crashes more accurately predicted crashes at horizontal curves. This study also investigated the effect of speed limit change on horizontal curve crashes on K-5 highway in Leavenworth County, Kansas. A statistical t-test proved that crash data from years 2006 to 2012 showed only significant reduction in equivalent property damage only (EPDO) crash rate for adverse weather condition at 5% significance level due to speed limit reduction in June 2009. However, the changes in vehicles speeds after speed limit change and other information such as changes in surface pavement condition were not available. According to the results of data analysis for 221 selected horizontal curves on undivided two-lane highways, tangent section length significantly influenced total number of crashes. Therefore, providing more information about upcoming changes in horizontal alignment of the roadway via doubling up warning sings, using bigger sings, using materials with higher retroreflectivity, or flashing beacons were recommended for horizontal curves with long tangent section lengths and high number of crashes. Also, presence of rumble strips and wider shoulders significantly and negatively influenced severe SV crashes at horizontal curve sections; therefore, implementing rumble strips and widening shoulders for horizontal curves with high number of severe SV crashes were recommended.

The purpose of this Thesis is to show ways of the selfmanagement and to include them into daily life. Using several publications I suggest possibilities of personal progress and its benefit for our life. I research the awareness about the selfmanagement and its principles. I lead the respondents to deeper thinking about their life attitude and self-respect. It is focused on purpose of living, life goals and principles, time management, self-control, a creativity and alternative ways to personal progress. I would like to explain connections between personal and working life. Well-balanced and creative person, who is cultivating himself, has better potencial for satisfied working life. The process of writing Master's Thesis was enriching and I hope it was also an inspiration for the respondents. I find it very important to focuse not only on outside world, but first of all on inside world. I wish the selfmanagement would come closer to more people and help them to build a happy life.

A thesis submitted to the School of Education, Faculty of the Humanities, of the University of the Witwatersrand in the fulfilment of the requirements for the degree of Doctor of Philosophy in Education JOHANNESBURG NOVEMBER 2015 / This study provides an analysis of the role of university councils in Historically Disadvantaged Institutions (HDIs) in bringing about effective governance. It adopts a case study approach of a single institution which became a comprehensive university following the Higher Education post-1994 transformation agenda in South Africa. The study explores the role of systems, structures and cultures of university councils in promoting effective university governance. It arises from widespread concern about poor university governance which has resulted in no less 10 institutions being placed under administration in the post-1994 democratic era. This study used a range of theoretical and methodological approaches. The theoretical approaches involved the use of the following concepts as an organizing framework: “structures of university councils”, “systems of university councils”, “cultures of university councils” and “empowered individuals” or “groups of individuals”. The methodological approaches involved data collection within a sequential-exploratory mixed methods research interpretive paradigm and the positivist research paradigms. The process of data collection involved; the use of institutional documents, interviews with 19 different members of the university council and study surveys with available 17 university teaching staff, 48 university non-teaching staff and 255 university students. The process of data analysis involved the use of content analysis, descriptive and inferential statistics. The results of this study show that the institutional structures of the university council are business oriented in organization although strongly characterised by institutional stakeholder relationships. This has led to effective governance practices being tied around forms of stakeholder propositions such as increased sectoral deployment of constituency cadres to champion particular stakeholder interest at the university council. The results of this study indicate this has led to conditions and instances where the systemic due processes of the university council are prone to stakeholder control. This is due to instances of unpreparedness for general council and committee meetings an outcome of sectoral deployment of individuals who have little if not no idea of the due processes at the systems level of the university council and reliance on informal stakeholder constituent networks as a mode of trust governance. This has led to less sovereignty for critical autonomy to check on strong stakeholder configurations at the university council leading to reproduction of dormant stakeholder interests. At the cultural level of the university council the results of this study show that to respond to these conditions the university council has become stakeholder managerial driven. The university council cultural governance actions as governance role practices are strongly stakeholder enthused. The implication of governance stance has caused contestations between the less empowered institutional stakeholders represented at the university council and the university council over practices that are seen as perpetuating marginalisation of the less empowered institutional stakeholders represented at the university council. As a result it has led to adoption of partisan modes of stakeholder institutional governance practices like caucuses, stakeholder deployment, protest, and unionisation. This thesis as a recommendation makes a case through an emerging model of university governance known as the structural-systemic-cultural university governance model. This model suggests that for the university council to be able to provide effective university governance in such comprehensive institutional contexts, it should take in consideration the following: At the structural level, governance should be characterised by practices that recognise the place of the university council in decision-making process in the university institution, governance capacity-building, networked committee regimes, effective representation and utilisation of delegated institutional governance spaces. At the systemic level, governance should be characterised by practices that value stakeholder contribution, support well-informed of committees of council, well informed constituents, accountability and compliance engagement as part of the core due processes of the university council. At the cultural level, governance should be characterised by practices that appreciate accessible governance spaces, accommodativeness, negotiated positions and shared accountabilities as part of the primary bases that characterise institutional culture of the university governing council. Key words: university council, structures, systems, cultures, effective university governance, comprehensive university
