Masters Thesis: Dynamic Wind Farm Control using the WFSim flow model

Renewable energy is becoming more and more important in today’s society. Wind energy plays an important role in the production of renewable energy. Due to economic advantages, wind turbines are often sited close together, creating wind farms. As a result, the wind turbines in the farm become interconnected due to the wakes of the turbines. In conventional wind farm control, this interconnection is ignored, and wind turbines are operated at their own local optimum. This control strategy is referred to as greedy control. In the wake of a turbine, the wind speed is reduced. As a result, the power production of a wind turbine that is situated in a wake is also significantly lower. The greedy control strategy may therefore not be optimal for wind farm control, which subsequently has been receiving an increasing amount of attention recently. Most research on wind farm control focusses on steady-state optimization, i.e., finding the optimal steady-state given certain constant conditions. Since wind flow is always subject to change, the potential gain of this procedure is limited. In this thesis, a closed-loop dynamic wind farm controller is presented using a Model Predictive Control (MPC) framework. The control objective is to maximize the power production of the wind farm, resulting in an economic MPC problem. As the optimal input is time-dependent, the number of control inputs and states involved increase as the prediction horizon of the MPC problem increases, resulting in a more complex problem than the steady-state optimization problem. As a model, Wind Farm Simulator (WFSim) is used, which is based on 2-dimensional NavierStokes equations. This results in a high-dimensional problem from which the optimum is unknown. The adjoint method is applied to determine the gradient of the objective function in a time-efficient manner. The controller developed in this thesis increases the power production of a wind farm with respect to the conventional greedy control stategy, and is able to adapt to changes in the atmospheric conditions. The adjoint-based MPC algorithm therefore shows real potential to perform real-time dynamic control on wind farms. Master of Science Thesis J.A. Frederik
HAEMATOLOGICAL PROFILE OF PREGNANT WOMEN INFECTED WITH MALARIA PARASITES AT FEDERAL TEACHING HOSPITAL ABAKALIKI, EBONYI STATE

Malaria in pregnancy is a major public health probl em in endemic areas of sub-Saharan Africa and has important consequences on birth outcome. There are subtle and substantial changes in hematological parameters of malaria in pregnancy. This work is de signed to ascertain the impact of malaria in pregna nt women visiting Federal Teaching Hospital Abakaliki II. Out of the 100 pregnant women screened for malaria, 44 (44.0%) were positive for malaria paras ite. Of the 44.0% pregnant women positive for malaria parasite, the age range of 26-30 years (31. 8%) were more infected with malaria parasite, followed by 21-25 years (22.7), while 41-45 (4.5%) years were the least infected. Pregnant women with no formal education were most infected (36.4%), fol lowed by primary education (27.3%), while secondary education showed the lowest rate of malar ia in pregnancy (13.6%). Housewives reported the highest cases of malaria in pregnancy, while studen t reported the lowest (9.2%). Married women showed the highest cases of malaria in pregnancy (79.5%), while widow reported the lowest (2.3). Christian reported in the highest cases of pregnancy in malar ia (46.0%) and Muslim the least (40.0%). The mean values of the haematological parameters of pregnant women with respect to parasitaemia were Heamoglobin (9.78±37.45 g/dL), Packed cell volume (31.56±2721.14%), White blood count (8.58±50.06◊10 3 /mm 2 ), Neutrophils (57.96±1004.97%), Lymphocyte (28.24±1392.97%), Mesophils (7.28±110.49%), Eosinophils (3.62±1156.91%) and Platelets (141.88±133873.07◊10 9 /l). This study have shown that the adverse consequences of malaria in p regnancy has great impact on heamatological parameters which may affect not only the neonate and infant but also increase the risk of non communic able diseases when the child grows into an adult and the risk of low birth weight in the next generation.
Measuring and explaining government efficiency in developing countries

Abstract Governments in developing countries play an important role in the growth process, most notably through their budgetary policies. This potentially beneficial role is, however, hindered by government expenditure inefficiency. This is illustrated in a basic model of public spending and economic growth. Government efficiency is estimated for 52 developing countries using data envelopment analysis and subsequently employed in a general to specific approach in order to identify its determinants. We find government expenditure efficiency is primarily determined by structural country variables and governance indicators. Economic policy determinants apparently count less. The Asian countries and low income European countries in the sample have a significantly higher and lower efficiency, respectively.
The Transformation of Sediment Into Rock: Insights From IODP Site U1352, Canterbury Basin, New Zealand

Abstract: At Integrated Ocean Drilling Program (IODP) Expedition 317 Site U1352, east of the South Island New Zealand, we continuously cored a 1927-m-thick Holocene-to-Eocene section where we can uniquely document downhole changes in induration and lithification in siliciclastic to calcareous fine-grained sediment using a wide range of petrological, physical-property, and geochemical data sets. Porosity decreases from around 50% at the surface to 5–10% at the base of the deepest hole, with a corresponding increase in density from ∼ 2 to ∼ 2.5 g cm 3 . There are progressive bulk mineral changes with depth, including an increase in carbonate and decrease in quartz and clay content. Grain compaction is first seen in thin section at 347 m below sea floor and intensifies downhole. Pressure solution (chemical compaction) begins at 380 m and is common below 1440 m, with stylolite development below 1600 m, and sediment injection features below 1680 m. Porewater geochemistry and petrographic observations document two active zones of cementation, one shallow (eogenetic) down to ∼ 50 m, as evidenced by micritic nodules and pore-water geochemistry driven by methane oxidation by sulfate, and another burial-related cementation zone (mesogenetic) starting at ∼ 300 m. A transitional zone occurs between 50 and 300 m. Our results quantify downhole diagenetic changes and verify depth estimates for these processes inferred from outcrop studies, and provide an actualistic example of cementation and compaction trends in a slope setting.
Physical and mechanical metallurgy of high purity Nb for accelerator cavities

In the past decade, high Q values have been achieved in high purity Nb superconducting radio frequency (SRF) cavities. Fundamental understanding of the physical metallurgy of Nb that enables these achievements is beginning to reveal what challenges remain to establish reproducible and cost-effective production of high performance SRF cavities. Recent studies of dislocation substructure development and effects of recrystallization arising from welding and heat treatments and their correlations with cavity performance are considered. With better fundamental understanding of the effects of dislocation substructure evolution and recrystallization on electron and phonon conduction, as well as the interior and surface states, it will be possible to design optimal processing paths for cost-effective performance using approaches such as hydroforming, which minimizes or eliminates welds in a cavity.
Beyond the CFA Franc: an empirical analysis of the choice of an exchange rate regime in the UEMOA

The CFA franc, originally created in 1945, currently serves as the common monetary unit for the eight member countries of the West African Economic and Monetary Union (UEMOA). In recent years, one has witnessed repeated calls from economists and politicians alike for the introduction of a new currency, which will be more reflective of fundamentals in UEMOA member countries' economies. This paper attempts to provide a road map for decision-makers in their choice of an exchange rate regime, when they decide to switch to a new currency. The model utilises an ordered logistic model to investigate which type of exchange rate regime - a currency board, a fixed but adjustable regime (FBAR), a managed float or a free float - will be appropriate for the Union in light of the economic and institutional fundamentals of its members. Our findings suggest that an FBAR will be the most suitable exchange rate regime, for it will have greater stimulus effects on investment and economic growth. The adoption of an FBAR will help UEMOA member states reach a two-fold objective: (i) to achieve sustained economic growth, (ii) while reinforcing the credibility and authority of their central bank, the BCEAO.
Acoustic Absorption of Conventional Pavements

Traffic noise is a growing problem throughout the world. Pavement with a high acoustic absorption capability can significantly reduce roadway traffic noise. The durability of such acoustically absorptive pavements is however a major concern for the highway application. The sound absorption capabilities of typical portland cement concrete (PCC) that were surface textured in different configurations and typical asphalt concrete (AC) were measured in the Centre for Pavement and Transportation Technology (CPATT) laboratory at the University of Waterloo, Ontario (Canada) using an impedance tube and a custom designed portable reverberation chamber. On average, the regular 12.5 mm SuperpaveTM (SP12.5), 12.5 mm stone mastic asphalt (SMA12.5), and the fine graded 12.5 mm SuperpaveTM (SP12.5Fine) mixes were shown to absorb 6.3%, 7.5%, and 8.5% of the sound energy, respectively. Textured PCC surfaces were shown to absorb 5-6% of the sound energy. The varying thickness has shown no significant effect on the variation of sound absorption of conventional dense AC and PCC pavements. The variation of bulk relative density (BRD) was shown to affect significantly sound absorption capabilities of the AC pavements. However, the effect of the air voids content in the dense AC mixes was shown to be insignificant or minimal for the variation of sound energy absorption.
Pre-service Teachers' Learning Object Development: A Case Study in K-12 Setting

Teachers use variety of media to support students’ learning. Though there are many new tools and settlements in learning technologies and their specifications, there has been a fierce debate over learning objects and their development. This research aimed to examine the effect of preservice teachers’ experience in information and communication technology (ICT) use on their learning object development through (1) inspecting type, number and organization of their learning object (LO) components authored in a non-commercial system, (2) evaluating quality of their learning objects using the Learning Object Review Instrument (Nesbitt & Li, 2004), and (3) studying relationship between the components, quality and subject matter of their LOs. Seventysix pre-service teachers were asked to design and develop LOs in a non-commercial learning content development system. Analysis of their learning objects and a usability test data showed that the participants found the system easy to use in general. Novice and experienced information technology users were able to develop learning objects similar in size and features. The analysis showed meaningful correlation between the use of some of the learning object components. There seems to be significant relations between the quality of the LOs measured with the LORI items and some elements of the developed LOs, however, the novice and experienced groups’ LOs did differ neither in overall ratings nor at nine individual items of the LORI. The study suggested some further work for developing quality LOs through collaborative learning resource authoring.
Mapping historians: historians' orientations and historical production

Narrative historians have long exhibited greater or lesser awareness of their own agency as authors, where absolute objectivity is precluded. Indeed, historians' reports of the past include their own orientations or attitudes, which can also be examined in historians' autobiographies. In this article we present a study in which a questionnaire was used to ask historians about their orientations toward their subject matter. How do historians approach their work as agents and what might this reveal about the nature of historical production? In our model, we have distinguished four criteria, sorted the answers using statistical analysis and weighed the results in the light of our expectations. Indeed, by exploring historians' presuppositions (exemplified in examining historians' autobiographies), historical production can be seen as an institutional process also steered by historians' orientations and agency with important philosophical implications for the integral relationship between historians' public and private roles.

Modelling the Zero-Inertia, Horizontal Viscous Da m-Break Problem

T his paper considers the dam-break problem in a horizontal smooth 1D channel, for hydrogeological hazards purpose. The fluid is muddy and it can be described by a Newtonian model, provided that the inertial effects be neglected versus the viscous ones in the momentum balance. Assuming the shallow water approximation, a non dimensional equation is built from the continuity and the Navier-Stokes equations in the limit of zero-inertia and solved analytically in two limits: short time and long time. These solutions are then combined into a single, universal model. Limitations of the model are examined by comparison to a converged finite difference numerical solution of the flow equation.
On the Application of Cognitive Behavioral Therapy in Treating Foreign Language Listening Anxiety

Cognitive behavioral therapy (CBT) is a set of treatments that focus on altering thoughts, sensations, emotions and behaviors by addressing identified maintenance mechanisms such as distorted thinking or avoidance. The aim of this study was to assess whether the use of CBT techniques in reducing foreign language listening anxiety is an acceptable intervention, and provide a description of many of the basic techniques used in CBT. These included: psychoeducation, relaxation exercises, exposure and cognitive restructuring. A feasibility study of a brief CBT intervention following training was conducted. Qualitative analysis was carried out on participant feedback from semi-structured interviews. The current article provided an interdisciplinary way for foreign language teachers to help college students reduce foreign language listening anxiety and improve learning achievements.
Open Innovation Implementation in the Service Industry: Exploring Practices, Sub-practices and Contextual

This paper addresses a major gap in reported research on open innovation (OI) literature: How do service firms adopt open innovation? This research focuses on data from eighteen service SMEs in Belgium from high-tech and knowledge-intensive service industries. Based on analysis, we find new insights regarding open innovation practices (i.e., inbound and outbound) and sub-practices (i.e., acquiring, sourcing, selling and revealing) for service firms. More specifically, the study showed that service SMEs are more inclined to use inbound practices due to reasons associated with firm size, industry, and knowledge intensity in the market, whereas the decision about which sub-practice to adopt seems to be strongly influenced by the type of actor, the firm’s vulnerability and internal managerial skills, and the existence of complementarities. Thus, we contribute to OI literature as well as capability literature through providing initial insights regarding the adoption of OI by service firms.
Exploring Consumers Attitude towards Web Advertising and its Influence on Web Ad Usage in Malaysia (Meneroka Sikap Pengguna terhadap Periklanan Laman Sesawang dan Pengaruhnya ke atas Penggunaan Iklan di Malaysia)

The digital age has already made significant changes to each of the elements of the promotion mix. Companies increasingly see the Internet as an important medium through which advertising messages can be directed towards consumers. In the 21 st century, consumers have more control over advertising exposure with web advertising because they can select how much commercial content they wish to view. However, very little is known of consumer beliefs about Web advertising, attitudes toward Web advertising or Web advertising associated with consumer behaviour in Malaysia. By adopting and applying Korgaonkar, Silverbatt and O’Leary’s measurements, this paper explores Web users’ beliefs, attitudes and use of Web advertising. The descriptive statistics, cross tabulation, factor analysis results as well as regression analysis and its implications on the findings are discussed.

General Relativistic Treatment of the Pioneers Anomaly

We consider a General Relativistic generalized RWs metric, and find a field of Universal rotational global centripetal acceleration, numerically coincident with the value of the Pioneers Anomalous one. Related subjects are also treated. The rotation defined here is different from older frameworks, because we propose a Gaussian metric, whose tri-space rotates relative to the time orthogonal axis, globally.
A Social Support Intervention to Reduce Intentions to Drop-out from Youth Sport: The GAA Super Games Centre

Research has highlighted that drop-out from youth sport has emerged to become a global trend with drop-out rates exceeding 30% in some countries. This study aimed to investigate the effect of a change in perceived support on intentions to drop out from youth sport at the end of a social support intervention. A pre-intervention examination of the Gaelic Athletic Association (GAA) in 2012 identified a 19.38% drop-out rate involving 3,491 participants between the ages of 12-16 years. A psychosocial intervention developed for the GAA called the Super Games Centre was delivered and evaluated over a 24-week period to 103 participants. The findings demonstrated that higher perceived available support was significantly associated with lower levels of intentions to drop out at the end of the intervention. Furthermore, social identity emerged as a significant mediating factor in explaining the association between changes in perceived support and intentions to drop out. A post-intervention examination in 2018 found that the GAA had established 95 Super Games Centres since 2015, and this has led to an increase in 7,012 new participants between the ages of 12-16 years. Future research and implications for social support intervention methodology are discussed.
A study on work engagement among nurses in Japan: the relationship to job-demands, job-resources, and nursing competence

Objective: This study reviewed the state of work engagement among nurses in Japan, and the relationship to job demands and job resources. Additionally, our research attempted to clarify the role of work engagement on the effects that job-resources have on nursing competence. Methods: A questionnaire composed of the Utrecht Work-Engagement Scale the Brief Scales for Job Stress-Nurse and the Clinical Nursing Competence Self-Assessment Scale was distributed to 917 nurses working in hospitals in Japan. Results: A negative correlation, although slight, was found between job-demands and work engagement. There was a positive correlation between job-resources and work engagement, however, work engagement was only found to be significantly affected by job fulfillment. Work engagement seems to mediate the relationship between job-resources and job-demands however the results from the path analysis did not fully support this model. Conclusions: Our study did not sufficiently explain the relationships between variables. It can be suggested that the correlations between job-resources, job-demands, and work engagement are bidirectional or circulatory, rather than unidirectional.

Chasing passive galaxies in the early Universe: a critical analysis in CANDELS GOODS-South

We search for passive galaxies at $z>3$ in the GOODS-South field, using different techniques based on photometric data, and paying attention to develop methods that are sensitive to objects that have become passive shortly before the epoch of observation. We use CANDELS HST catalogues, ultra-deep $Ks$ data and new IRAC photometry, performing spectral energy distribution fitting using models with abruptly quenched star formation histories. We then single out galaxies which are best fitted by a passively evolving model, and having only low probability $( 3$ is still subject to significant uncertainties, being sensitive to assumptions in the SED modeling adopted and to the relatively low S/N of the objects. By means of dedicated simulations, we show that JWST will greatly enhance the accuracy, allowing for a much more robust classification.
