An Evaluation of How Well Undergraduate Property Students are Prepared for Commencing their Careers

Abstract The evolution of property education to adapt to the changing business environment requires changes to course content, methods of delivery and assessment. Many universities have a special interest in understanding how successfully students transition in and transition out of property programs. This study sought the views of final year students engaged in professional employment, employer representatives and representatives from professional associations to assess the preparedness of students to commence professional employment. The study showed that generally students possessed an appropriate level of technical and ‚soft skills‛ to enter the professional realm with development required in some areas. All stakeholders agreed that the transition out of university was made more seamless through greater engagement with industry through field work and work experience from the intermediate stages of the property course.

Implementing remote image capture/control in a wireless Sensor network utilizing the IEEE 802.15.4 standard

Abstract : Today's warfighter requires an in-depth view of the battle space in order to best plan for future operations, assess the current operating environment, and prevent or respond to attacks. The deployment and use of wireless sensor devices could serve as a force multiplier by enhancing a commander's security posture, providing a view of the current environment, and gathering intelligence for analysis. The use of low-power imaging devices, coupled with the flexibility provided by a wireless sensor network, could provide such enhancements. The objective of this research was to explore the feasibility of remote management and control of a low-power/low-cost wireless sensor network by implementing a point-to-point wireless network utilizing IEEE 802.15. 4 equipped devices to control, capture, and transfer image data from a remote sensor node to the controlling host. This platform was used to test the viability of the system at various ranges and operating environments. The results demonstrated that the IEEE 802.15. 4 compliant devices used in this research are able to operate over long distances (1000 meters), in harsh RF environments, with a high degree of reliability.
A Comparative Study on Meta-Heuristic Algorithms For Solving the RNP Problem

The continuous increases in the size of current telecommunication infrastructures have led to the many challenges that existing algorithms face in underlying optimization. The unrealistic assumptions and low efficiency of the traditional algorithms make them unable to solve large real-life problems at reasonable times.The use of approximate optimization techniques, such as adaptive metaheuristic algorithms, has become more prevalent in a diverse research area. In this paper, we proposed the use of a self-adaptive differential evolution (jDE) algorithm to solve the radio network planning (RNP) problem in the context of the upcoming generation 5G. The experimental results prove the jDE with best vector mutation surpassed the other metaheuristic variants, such as DE/rand/1 and classical GA, in term of deployment cost, coverage rate and quality of service (QoS).
Low switching frequency modulation scheme for high power three level converters: FPGA based implementation

The demand for electrical motors with high power ratings is increasing in different applications, especially in the offshore industry. The power rating of these motors can be raised by increasing the voltage at the motor terminals to a higher value. This method has the drawback of increasing the losses due to harmonic currents although it fulfills the requirement of increasing the power. An equally important reason to look for a more efficient modulation strategy is that it is not efficient to operate the medium voltage converter at the same switching frequency as the conventional low voltage converters because of high switching losses. To tackle these problems, the PWM technique should be implemented in such a way that it produces the lowest possible harmonic content in the load current. A low switching frequency implementation of the proposed PWM strategy is also an important requirement to alleviate the mentioned problems. One of the ways to do this is programming the pulse patterns so that the total harmonic content fulfills the maximum tolerable harmonic content. In this master? s thesis, techniques to produce the optimal pulse patterns for the motors were studied. First, the mathematical relations that govern the relation between optimal patterns and the required output voltage level were dealt with. Second, a brief study of the Digital control technologies for the implementation of the modulation principle was made with focus on Xilinx FPGA. The flexibility of FPGA based system together with its ability to execute instructions at hardware level made it an ideal choice for the implementation of the proposed modulation scheme. After having mastered the overall development environment of Xilinx FPGA through the studies, the project design, both software and hardware, for the problem in hand was done using the tools. Last, the software program that produces the optimal patterns for a certain variation of number of pulses and modulation indices was successfully developed on the FGPA processor. Finally, an investigation was done on the output waveforms produced by the optimal patterns. It was observed that the pattern change happens as desired, and the optimal patterns produce the required sinusoidal waveform with harmonics less than that which would occur in conventional PWM techniques.
Early developmental experiences of professional golfers: a case study from the UK

Various models of talent and player development in sport exist which attempt to describe how to achieve expert levels of performance (e.g. Bloom, 1985; Cote et al., 2007). In addition, research exists which suggests that expert performance can only be attained by practicing in a unique special way with tight constraints and covering a minimum period of time (e.g. Ericsson et al., 1993). This study was designed to explore how a case study of seven golfers developed their skills and acquired enough golf expertise to turn professional. Successful Professional Golfers’ Association (PGA) golfers from England were interviewed to explore how they developed and attained their expertise. The research was predominantly interpretive but partially deductive due to the tenets of the theoretical framework used in this study (Cote et al., 2007), which promoted ‘Deliberate Practice’ theory within it. The data that emerged was inductively analysed and explanations given. The findings provide support that expertise in golf is developed over a minimum average period of at least ten years. The process involves phases of development based on attitude to continue. It was discovered that these phases were non-linear as proposed in certain models (e.g. Balyi & Hamilton, 2004; Cote et al., 2007).
Dosimetry of Exposure to Electromagnetic Fields in Daily Life and Medical Applications

textabstractElectromagnetic fields (EMF) are present everywhere in our environment but are usually invisible to the human eye. EMF for example generated by mobile phones and 50Hz power lines, can cause electric fields, currents and tissue heating in the human body. In the past, exposure limits were developed to avoid adverse health effects. These limits were derived from dose assessments using simple models which for example approximate the human by homogeneous spheroids. Nowadays, state-of-the-art electromagnetic models enable to predict and visualize the propagation of electromagnetic waves in the human anatomy. These models can provide detailed information on the exposure of the general public in daily life situations and those of patients and staff in medical applications such as hyperthermia treatments of cancer and Magnetic Resonance Imaging (MRI). In this thesis, a comprehensive assessment of the exposure to different EMF sources is provided for both children and adults. An evaluation is made how the guidelines, based on simple models, translate to the dose in complex anatomies in various population groups. Further, it is demonstrated that validated electromagnetic models can be used for the benefit of medical applications, by providing the medical staff a clear picture of the actual applied dose in patients and by efficient virtual prototyping of improved medical devices.

Development of a Semi-Autonomous Scale Dragline Excavation Research Tool

In open pit coal mines of the Bowen Basin and Hunter Valley region, draglines are responsible for the largest share of overburden excavation. These machines operate 24 hours a day, seven days a week. Previous research has calculated that for every per cent increase in efficiency the benefit to the mine is roughly one million dollars per annum. Due to the high opportunity cost for a dragline any downtime is unfavourable. Thus sufficient access to an operational dragline for research purposes is a key problem. One solution to this problem is to use scale models. There are however many problems associated with implementing a scale dragline. Operator variability has been shown to be as high as 40 per cent. This may be due to many reasons such as; digging style, skill level or fatigue. Using human operators on a scale dragline will generate the same type of variability. Material properties such as particle size distribution, moisture content, rock shape, rock length, overburden composition variability can also significantly impact digging performance. Careful consideration of the material properties is required to achieve similarity between scale models and real scale draglines. This paper presents the development of a semi-autonomous scale dragline to address these problems. An automated digging algorithm that eliminates the variability of a human operator tackles operator variability. As the dig algorithm will always respond with the same digging style, results are reproducible. The problem of material variability has been eliminated by measuring material properties from a coal mine and accurately reproducing those properties in scale. The combination of a computer controlled digging algorithm and accurately scaled materials produces results that are statistically similar to real full scale dragline results.
Free-Piston Stirling Convertor Controller Development at NASA Glenn Research Center

The free-piston Stirling convertor end-to-end modeling effort at NASA Glenn Research Center (GRC) has produced a software-based test bed in which free-piston Stirling convertors can be simulated and evaluated. The simulation model includes all the components of the convertor - the Stirling cycle engine, linear alternator, controller, and load. This paper is concerned with controllers. It discusses three controllers that have been studied using this model. Case motion has been added to the model recently so that effects of differences between convertor components can be simulated and ameliorative control engineering techniques can be developed. One concern when applying a system comprised of interconnected mass-spring-damper components is to prevent operation in any but the intended mode. The design mode is the only desired mode of operation, but all other modes are considered in controller design.
The destabilisation of existing regimes in socio-technical transitions: theoretical explorations and in-depth case studies of the British coal industry (1880-2011)

This thesis, which addresses an innovation studies audience, deals with a neglected topic in the study of socio-technical transitions: the destabilisation and decline of established industries. While most of the transitions literature focuses on the emergence of novelty, this thesis investigates the productive role of destabilisation and processes of unlocking of existing regimes. The research question is: How can we understand the unfolding of industry destabilisation processes? To answer this question, this thesis aims to make theoretical contributions by developing an integrative framework that overcomes shortcomings in existing views of destabilisation. Insights from a number of different approaches are mobilised as ‘building blocks’ for theoretical elaboration. Destabilisation is understood as a process involving: 1) multiple interacting pressures, 2) industry strategies and responses to (economic and legitimacy) challenges, and 3) decreasing commitment to industry regime rules. The theoretical perspective addresses: a) destabilisation as a long-term unfolding process, b) the multi-dimensional and co-evolutionary nature of destabilisation, and c) the role of normative problems in destabilisation. To assess the robustness of the conceptual perspective, the thesis studies three cases of destabilisation: - The destabilisation of the British coal industry in the transition from the omnipresence of coal to a four-fuel economy (1880-1967) - The destabilisation and decline of British deep coal mining in the electricity sector (1967-1997) - The destabilisation of coal use in the transition towards low-carbon electricity (1990-2011). Possible revival? The case studies show the usefulness of the conceptual framework. The analysis of patterns and causal mechanisms further identifies similarities and differences of destabilisation pathways in the cases. Specificities in the kinds, rates, interaction and timing of these dynamics produce different destabilisation patterns.
Silicon Carbide Temperature Monitor Measurements at the High Temperature Test Laboratory

Silicon carbide (SiC) temperature monitors are now available for use as temperature sensors in Advanced Test Reactor (ATR) irradiation test capsules. Melt wires or paint spots, which are typically used as temperature sensors in ATR static capsules, are limited in that they can only detect whether a single temperature is or is not exceeded. SiC monitors are advantageous because a single monitor can be used to detect for a range of temperatures that may have occurred during irradiation. As part of the efforts initiated by the ATR National Scientific User Facility (NSUF) to make SiC temperature monitors available, a capability was developed to complete post-irradiation evaluations of these monitors. As discussed in this report, the Idaho National Laboratory (INL) selected the resistance measurement approach for detecting peak irradiation temperature from SiC temperature monitors. This document describes the INL efforts to develop the capability to complete these resistance measurements. In addition, the procedure is reported that was developed to assure that high quality measurements are made in a consistent fashion.
GETTING CLOSER TO THE THINGS WE ARE LOOKING FOR - A PROPOSAL FOR ASPECT-DRIVEN TEXT ANALYSIS

Locating facts in texts is still a challenge for retrieval systems. Instead of measuring the relevance of the entire text for a search query, the focus of our approach of fact retrieval and text mining is on spotting only essential parts of text. We propose to enrich search queries by aspects supporting highly precise retrieval. An aspect denotes the unique interpretation of a set of words that appear in close proximity. We conceive an aspect representation as a hierarchical structure composed by its semantic elements that, in turn, constitute the aspect’s implicit meaning. In this paper, we present the definition and application of aspect blueprints that serve as standardized representations of aspects. Our prototypical system Contexter operates on these blueprints and locates facts in texts. In a semi-automatic way, the system tries to detect variants of blueprints that the user can confirm or reject. Here, we illustrate our approach and system in the realm of economic information.

The relationship between teacher academic optimism and student academic achievement: A meta-analysis

: This meta-analysis of 13 studies examines the relationship between teacher academic optimism and student academic achievement. The studies have been reached from Web of Science, ERIC, Proquest Digital Dissertations, Turkish Academic Network and Information TR Directory, Google Academic and Council of Higher Education Thesis Center databases. The correlation scores of the studies included in the meta-analysis were computed by the Fisher z method and Comprehensive Meta-Analysis V3 (CMA) Program was used. As a result, the relationship between teacher academic optimism and student academic achievement has a strong effect size with a value of 0.513 according to the random effects model. Additionally, the moderator analysis was performed for verbal and non-verbal courses. There was no statistically significant difference observed and no publication bias in the meta-analysis study. Education policy makers and school administrators can put on their agenda the strengthening of teacher academic optimism for student academic achievement.

Simple approximate solutions to continuous-time-random-walk transport. Technical report. [Applied to charge transport in amorphous materials]

Abstract : This paper presents a procdure for obtaining simple approximate solutions to the continuous-time random walk (CTRW) as it applies to charge transport in amorphous materials. Application of this procedure to a particularly simple trial function leads to an approximate solution that is in excellent agreement with the exact solution for the case in which it is known. The approximate solutions have proved to be very useful in applications of the CTRW theory to observable transport processes such as transient charge relaxation, following exposure to pulsed ionizing radiation, in thin films of amorphous insulators used in metal-insulator-semiconductor capacitors.
