Abstract:

<span>Transmission line is one of the important elements in the process of power transfer from the source of generation to the consumer. In order to analyze the performance of a transmission line, it has to be represented by an equivalent model with suitable circuit parameters at a per phase basis. The line models are used to measure voltages, currents and the amount of power flow depending on the line length. Transmission line performance is determined by the voltage regulation and its efficiency under their normal operating conditions. In this study, a systematic approach was developed in order to assists the lecturers in teaching this important topic to the students despite so many complicated mathematical equations involved in the calculation. With the aid of Graphical User Interface (GUI), the performance of transmission line can be determined and monitored due to the change of line parameters. The results obtained could assist the lecturers in delivering the concept of engineering in a more systematic approach. On top of that, it could also assist the power system utility in planning the transmission line that needed to be installed in the system.</span>

Abstract:

In this paper, quasi-oppositional teaching-learning based optimization (QOTLBO) is introduced and successfully applied for solving an optimal power flow (OPF) problem in power system incorporating flexible AC transmission systems (FACTS). The main drawback of the original teaching-learning based optimization (TLBO) is that it gives a local optimal solution rather than the near global optimal one in limited iteration cycles. In this paper, opposition based learning (OBL) concept is introduced to improve the convergence speed and simulation results of TLBO. The effectiveness of the proposed method implemented with MATLAB and tested on modified IEEE 30-bus system in four different cases. The simulation results show the effectiveness and accuracy of the proposed QOTLBO algorithm over other methods like conventional BBO and hybrid biogeography-based optimization (HDE-BBO). This method gives better solution quality in finding the optimal parameter settings for FACTS devices to solve OPF problems. The simulation study also shows that using FACTS devices, it is possible to improve the quality of the electric power supply thereby providing an economically attractive solution to power system problems.

Abstract:

This article presents a novel improved teaching learning based optimization (I-TLBO) technique to solve economic load dispatch (ELD) problem of the thermal plant without considering transmission losses. The proposed methodology can take care of ELD problems considering practical nonlinearities such as ramp rate limit, prohibited operating zone and valve point loading. The objective of economic load dispatch is to determine the optimal power generation of the units to meet the load demand, such that the overall cost of generation is minimized, while satisfying different operational constraints. I-TLBO is a recently developed evolutionary algorithm based on two basic concepts of education namely teaching phase and learning phase. The effectiveness of the proposed algorithm has been verified on test system with equality and inequality constraints. Compared with the other existing techniques demonstrates the superiority of the proposed algorithm.

Abstract:

This study proposes an algorithm to allocate different types of flexible AC transmission system (FACTS) in power systems. The main objective of this study is to maximize profit by minimizing the system’s operating cost including FACTS devices (FDs) installation cost. Dynamic and steady state operating restrictions with loads uncertainty are included in the problem formulation. The overall problem is solved using both teaching learning based optimization (TLBO) technique for attaining the optimal allocation of the FDs as main-optimization problem and matpower interior point solver (MIPS) for optimal power flow (OPF) as the sub-optimization problem. The validation of the proposed approach is verified by applying it to test system of 59-bus; Simplified 14-Generator model of the South East Australian power system.

Abstract:

Aim. The aim of the research is the comparative study of literary cat characters in Children’s Literature texts in Greek and Spanish and their instructive function in the transmission of social stereotypes. Methods. The research subscribes to the field of Literary Animal Studies based on the theory of Children’s Literature (Lukens, 1999) and through the intercultural perspective of Comparative Children’s Literature (O’Sullivan, 2005). Published children’s books from Greece, Spain and Spanish-speaking America were compared using textual analysis methods of Imagology (Beller & Leersen, 2007). Stereotyped variants were identified and organized in categories related to name, physical appearance, gender, behavior, and function of literary cat characters. Results. After examining a corpus of 37 books, 23 in Greek and 17 in Spanish (Argentina, Chile, Colombia, Mexico, Spain), textual analysis findings were compared, organized, and classified by language, country and readers’ age groups to locate that literary cat characters are usually pets or feral, and they remain consistently stereotyped as anthropomorphic and subversive. Cats with seven lives and magical powers are common perceptions, dominating in both cultural contexts, stereotypes extended to strong superstitions about black cats. Conclusions. In Children's Literature texts, cats are linguistically, literally, and socially defined literary constructs, can have usually human-like features, intercultural influences, and are potentially shaped by intertextual relations. They serve also as a narrative motif for the transmission of social values about non-human animals and the textual familiarization of nonadult readers with society’s cultural stereotypes.

Abstract:

Subject area Intergenerational transmission is a paramount managerial and patrimonial issue. Although planning and governance tools are being developed and spread in business, the handling of emotions often remains the key to a successful process. It is within the framework of the paternalistic Moroccan society that we are led to question the psychology and emotions of the stakeholders in the transmission of this small services business. Study level/applicability Masters students in Family Business, Management Science, Entrepreneurship, Small Business Management. Case overview After 19 years of existence, Moroccan Shipping is confronted at the beginning of 2010 to the issue of the sustainability of the family business. The founder directs his affair with an iron fist, and his sons, who were educated abroad, are determined not to get fooled. The father claims he wishes to be relieved from daily operations and handover part of his responsibilities to his second son. At the same time, the youngest doesn't feel like he fits in the present firm's configuration and is ready to quit. Expected learning outcomes This case study will lead users to work on several managerial dimensions of small family businesses in emerging economies. At first, the entrepreneur's traits might be highlighted, as they deeply affect the way the succession process may be handled. However, as the Middle East and North Africa (MENA) specificity, the Moroccan family system will be taken into consideration to better analyse both the incumbent and the successor behaviours. Management tools may then be discussed to help with the transfer of both power and ownership in family businesses. Supplementary materials Teaching Notes are available for educators only.

Abstract:

In today’s teaching environment where students’ main focus is on getting a high mark for a class, deep understanding has taken a backseat. Being able to answer as many exam preparation questions as possible and fulfilling all the criteria on an assignment will guarantee success. “I deserve a higher mark because I worked hard in this class,” are the arguments one hears after the final marks are published. How about understanding the new material presented in the class? Engineering sketching and journaling have been hailed by experienced engineers as tools to enhance thinking and communication. The authors of the paper report about their utilization as teaching tools to foster deep understanding in a course on construction equipment and methods. While topics like equipments economics, power transmission and safety benefit from graphing in two-axis coordinate systems, understanding the best path of a backhoe bucket during a trenching operation is impossible to describe in words. Of course, understanding has several components: a) WHY do we use a backhoe excavator and not a trencher, b) WHAT are the possible three link motion paths and their related force vectors, c) HOW can the operator control the path of the bucket, and d) WHAT-IF there are utilities buried in the ground?

Abstract:

This article is a comparative study of the education system in minority languages between Catalonia and Australia from a legal standpoint. Catalonia has a complex legislation: National Constitution, Statute of Autonomy, Regional Laws, a strong legal framework, a language always alive as a political instrumentto get the power. Australia has not a legal framework in this area and has a confused planning system. In Europe, the Council of Europe has been in charge of the protection of human rights.Australia signed and ratified some International Conventions which are not a strong legal basis to claim an education system in aborigines’ languages. The Catalan Law on Linguistic Normalizationn. 7 of 1983, replaced by the Law on Linguistic Policy n. 1 of1998, has, among the other purposes, also that to stimulate the use of Catalan as language of education in all levels of teaching.The school has a fundamental importance for the transmission of the culture of minorities. If the educational systems didn’t have any regime of teaching in the mother tongue all policies are not efficient.

Abstract:

A representative cross-sectional study was conducted to assess the knowledge about toxoplasmosis prevention, transmission routes, clinical features, and who can be infected among students from seven teaching areas of the State University of Maringá, Southern Brazil, using a self-administrated questionnaire. A total of 600 students participated in the study, 86 students did not answer or did not know about toxoplasmosis (14.3%), the other 514 (86.2%) had some information about toxoplasmosis and answered the questionnaires and most of them are unaware of the routes of transmission and prevention of this zoonosis. Less than 50% considered correct the options "do not feed cats with raw meat" (39.9%), "eat only well-cooked meats" (40.1%), and "ingest only filtered or boiled water" (42.6%). Also, misconceptions about prevention were identified when statements such as "doing fecal exams regularly" were considered correct by 20.0% of participants. Students' average of correct answers in the health and biological areas was statistically higher than in other areas. The agricultural sciences area had the worst performance. In conclusion, there is a critical need for effective educational programs to increase the population's awareness of toxoplasmosis since correct preventive practices are critical to control and reduce one disease's infection without definitive treatment.

Abstract:

Accepting the role for cognitive transmission means recognizing that humans are not empty slate at birth. The basic assumption is that every human being is born by bringing fitrah and equipped with various potentials and abilities that are different from other humans. With that provision, he then learns: first through things that can be sensed by using his five senses as a window of knowledge; then gradually from things that can be sensed to the abstract, and from what can be seen to be understood. This study aims to describe the concept of cognitive learning processes in Islamic perspectives between contradictions and contradictions with the western cognitive learning concept. From the results of the discussion it was concluded that: cognitive learning and teaching are more responsive to the power of their instincts because they are purely related to the ability to develop rational abilities (reason). Many found contradictions and defects in their theories, so that revisions and emerging new theories of cognitive succession. While in Islam there is only one verse "And Allah takes you out of your mother's stomach in a state of not knowing anything, and He gives you hearing, sight and heart, so that you are grateful" (An Nahl: 78) is able to break the concept of response to the instinctive power in terms this is called scular and in Islam there has never been a secular tradition that separates religion from life

Abstract:

Purpose of the study: The study is aimed to examine working-class everyday culture gender regimes in modern Russia. The research is focused on intergenerational transmission of gender-normative patterns, macro-policy of power and domination in working-class families, forms of their discursive production and legitimation. Methodology: The empirical base is represented by 30 biographical interviews with the informants aged from 21 to 33, living in Tyumen city and working in the field of industry, technical maintenance, and customer service. Reflexive analysis based on the categorical field of phenomenology and social constructionism, as well as data coding procedures, has been used as the main research tool. Main Findings: It was found that the normative pattern of a male breadwinner, having power in a family-based on control over economic resources, still dominates among young working-class men and actively supported by the majority of young women. The financial and status dominance of a man does not cause doubts in his leadership but when a woman plays a crucial role in providing for the family, informants tend to talk about “equality” in the family. Applications of this study: The results of the study can be used in the teaching of sociology, gender studies, and cultural studies; it can also be applied by local policymakers while developing social policy programs targeted on the regarded social group. Novelty/Originality of this study: In the current research we have examined a particular social group at the intersection of three stratification features: social class, gender, and age. The approach of “agency within the structure” provides an opportunity to carry out a deep sociological analysis of the relations between the macro-social and personal aspects of the gender regimes framing.

Abstract:

Although in many educational contexts textbooks serve as the backbone of teaching, providing practical guides for teachers as well as useful references for learning progress, they could also serve as a site of struggle for many competing discourses. ELT textbooks bear particular relevance here, as they place English at the center of prominence while serving as a medium for knowledge transmission. This paper reports on part of the findings of a case study examining the exercise of dominant discourses in two ELT textbooks for high school in Indonesia. The analysis revealed that there are imbalanced power relations—enacted through such discursive strategies as foregrounding,, backgrounding and framing in two areas: topics and visuals. These strategies were understood as part of the author’s attempt to preserve the hegemonic status of English and its associated dominant ideology in ways that reflect traces of linguistic imperialism. With regard to the pedagogical value of the textbooks, this paper offers some suggestions on how the textbooks could be more engaging and culturally sensitive towards learners’ socio cultural context. The discussion concludes with an appeal for more balanced representation between the discourse of the third world and that of Britain in ELT textbooks in Indonesia.

Abstract:

Background: Pertaining to increasing incidence of HIV/AIDS among youths, it becomes a need of the hour to make them aware about every aspects of disease. Students of secondary and higher secondary school can be targeted for achieving this goal. The objective of the study was to assess the knowledge about HIV/AIDS among the school students before and after giving educational intervention.Methods: An educational interventional study was carried out among school going adolescents of one of the school situated in the field practice area of one of the rural teaching hospitals of Gujarat. Pre-designed and pre-tested proforma was used for pre and post test study. Educational intervention in the form of power point presentation was conducted on various aspects of HIV/AIDS.Results: Around 163 students participated in the study. Mean age of the students were 16.6±0.7 yrs. Among them, 148 (90.8%) have heard about HIV/AIDS and only 26.3% could tell correctly about full form of HIV/AIDS before intervention. After giving educational intervention this percentage was raised to 89.2% which was significant statistically. Knowledge on almost all the aspects viz. modes of transmission and preventive aspects were significantly raised among the student after giving educational session.Conclusions: Correct knowledge about etiological and preventive aspects were lacking among the students before intervention. Various misconceptions which were prevalent among them were cleared by giving educational intervention. Secondary and Higher secondary schools can be selected as a platform for raising overall awareness about HIV/AIDS.

Abstract:

In rapidly changing social, economic and intellectual environments it is imperative that teaching and learning should be transformed from being primarily concerned with the transmission of knowledge (learning about) to being primarily concerned with the practices of a knowledge domain (learning to be). Law lecturers are faced with a new generation of law students, many of whom may be the first in their families to enter university, and one of the important challenges that we face, when educating law students, is how to enable these students to take their place in a very important profession. To meet this challenge it is necessary to instill skills that will be beneficial to the profession, future clients and the community as a whole. We at the University of Johannesburg are endeavouring to do so through embracing a therapeutic jurisprudence approach that focuses on the well-being of the student, the client and the community. The integration of therapeutic jurisprudence throughout the law student's studies, starting with orientation and continuing through to the final-year clinical experience, will enhance the therapeutic outcomes for all of the parties involved. A therapeutic jurisprudence approach, combined with appropriate teaching and learning methods, will enhance the student's interpersonal skills and writing and reading skills. The teaching methods invoked include role-play to transform formal knowledge into living knowledge, thereby stimulating students' natural practical curiosity and creating a learning environment that supports collaboration and encourages students to act purposefully in such an environment. This article discusses the teaching of first-generation students and how to overcome the existing social, cultural, economic and linguistic barriers by using a therapeutic jurisprudence approach, while upholding the values that should guide legal practice, such as integrity and respect for diversity and human dignity. The constitutional imperative of access to justice for all underlines the importance for law teachers of incorporating therapeutic jurisprudence in their teaching methods. In South Africa, law lecturers face many challenges in teaching law students and first-generation students. Passionate teachers will produce passionate students and realise that they have the power to transform thoughts, policies and lives. Students should be reminded that law is not just about financial rewards, but the ultimate reward of contributing to the betterment of society. The legal profession expects us to produce a well-rounded graduate for entry into the profession. This necessitates that our teaching methods be appropriate to prepare the student for an entry level of competence for the legal profession. Therapeutic jurisprudence creates the opportunity for the lecturer not only to equip the student with the skills required by the profession but to implement teaching methods that will prove to be beneficial for all of the role-players involved. The honing of skills such as legal writing and oral advocacy from the first year of study creates the opportunity for the students to develop to their full potential. In order to support a meaningful, integrated teaching approach, the development of skills is expanded on during each year of study and can prove beneficial to all role-players during clinical education, where the student has the opportunity to apply the acquired skills in real-life situations. The impact of a therapeutic jurisprudence on the development of legal skills can now be measured through the student's ability to focus on the well-being of the client and the community.

Abstract:

Resumo Nas últimas décadas, a pesquisa em Ensino de Ciências tem evidenciado a relevância do papel desempenhado pela História da Ciência no ensino e aprendizagem das mesmas. É tão importante aprender ciências como aprender sobre ciências e esta compreensão sobre o que é a ciência envolve tanto reconhecer a sua inserção num contexto social, como também ter uma ideia de como é construído o conhecimento científico e de que forma este se diferencia dos saberes do quotidiano. A metodologia de Ensino Baseado em Casos (EBC), rompeu décadas de ensino meramente transmissivo e enquadra-se na perspetiva socioconstrutivista da aprendizagem, onde o professor é mediador e os alunos trabalham em grupos e aprendem com os seus colegas. Esta metodologia de ensino parece assim vantajosa, uma vez que os alunos desenvolvem habilidades de trabalho colaborativo e resolução de problemas, além de dotar os alunos com âncoras mentais para os fatos, conceitos e princípios a serem estudados e assimilados. Reconhecendo a potencialidade desta metodologia de ensino e a faculdade da HC no ensino das ciências, foi proposto um caso que espelha a história do avanço científico e tecnológico dos pacemakers cardíacos. O estudo, ainda em desenvolvimento, irá incidir numa amostra de conveniência (n=26) constituída por alunos do 9o ano de escolaridade de uma escola pública de uma zona urbana do norte do país. Palavras-chave: História da Ciência; ensino baseado em casos; pacemakers cardíacosAbstract In recent decades, research in science education has highlighted the importance of the role played by HC in teaching and learning. As Matthews (1995), is so important to learn how to learn science as to learn science. This understanding of the Science involves both recognize the insertion in a social context, your as well as get an idea of how scientific knowledge is constructed and how this differs from knowledge of everyday life. The case-based teaching methodology broke decades of teaching merely transmissive and fits on social constructivism theory perspective of learning, where the teacher is a mediator and the students work in groups and learn from their colleagues. This teaching methodology seems so advantageous, since students develop job skills and collaborative problem-solving, in addition to providing students with mental anchors for the facts, concepts and principles to be studied and assimilated. Recognizing the potential of this methodology of teaching and the power of HC in science teaching, it was proposed a case that mirrors the history of scientific and technological advancement of pacemakers. This study, still under development, will focus on a convenience sample (n=26) consisting of students from the 9th grade level of a public school in an urban area in the north of the country. Keywords: history of science; case-based teaching; pacemakers.

Abstract:

PurposeThe study aims at exploring the perspective of three English as a Foreign Language teachers after their year-long involvement in the Lesson Study project in the context of Kazakhstan in order to capture and list any perceived changes in teachers’ educational beliefs over the period of the Lesson Study intervention. The main argument of the study suggests that the school-based Lesson Study initiative is conducive to triggering changes in teachers’ educational beliefs, and thus, might lead to positive changes in school culture in Kazakhstani schools. Shaped following Hill et al., (1982) in Swales, 1990 hour-glass model of a research project (Swales, 1990), the article reflects the third concluding part of the Ph.D. thesis focusing on the implementation of the Lesson Study methodology in Kazakhstan.Design/methodology/approachThe study adopts the qualitative research design and follows the narrative inquiry methodology. The three narrative interviews (Bauer, 1996) are utilized as the main method of data collection. The data were analyzed as text following a general inductive approach (Thomas, 2003), where emerging themes were identified employing data reduction and further sub-categorized through the conceptual and theoretical lenses of the study. The emerged categories reflecting the perceived shifts in teachers’ educational beliefs were dialectically linked to implications for school culture in Kazakhstani schools.FindingsAs data suggest, the respondents’ active engagement in the Lesson Study professional learning community and exercising leadership through implementing changes in their classroom practice has made a positive impact on teachers’ rethinking their teaching practice, attitudes to students and their learning, collegiality, and professional self-identification. We conclude that, if organized properly, Lesson Study has enormous potential to facilitate changes of teachers’ educational beliefs: from direct transmission beliefs toward constructivist beliefs, from restricted professionals’ beliefs toward reflective practitioner beliefs and attitudes, toward beliefs in the power of student’s voice, and collaboration. Those shifts are linked to establishing a more positive, child-friendly and rights-based school culture with teachers’ shared visions and capacity for innovation.Research limitations/implicationsWe acknowledge that the abundance of the reported positive changes or perceived shifts in teachers’ thinking might not be the indicators of actual changes in their beliefs. We emphasize that the study was carried in a controlled context, i.e. the three ELF teachers were constantly supported, and the teacher talk was systematically guided by a trained facilitator. Warned by Giroux et al. (1999), we are aware of the major challenge of the fundamental assumption of critical pedagogy that teachers are willing and able to undertake “the practice of analyzing their practice” (p. 27) voluntarily. Thus, the question remains open: if the facilitator’s support is eliminated, will the results point to the occurrence of the disruption and disorientation as a necessary condition for the beliefs change?Originality/valueCarried out in the largely overlooked by the academic literature context of the Reform at Scale (Wilson et al., 2013) in Kazakhstan and building on the original combination of conceptual and theoretical lenses, the research contributes to the academic literature by connecting teachers’ educational beliefs, Lesson Study and school culture. The findings might be of value for the school leaders, educators, teacher trainers, and policymakers to advocate Lesson Study as a systematic approach to the whole-school improvement, as a tool to facilitate positive changes in school culture, as well as give impetus to studies employing the school culture perspective in developing Lesson Study impact evaluation tools.

Abstract:

According to Bingham rheological model, the paper describes the technique of hydraulic power transmission based on the Magnetorheological fluid (MRF). As we all know, the MRF is an intelligent material, and it is used as the medium by which the power and signal can pass. Therefore, utilizing rheological behavior of MRF, the rheological state and viscosity of MRF can be directly modulated by electromagnetism field to control the speed, move direction and pressure of hydraulic system. We can gain an intermediate drive -control mode, which possesses many advantages such as: super stability, accurate precision, fine reliability, cheap cost and quick response and so on. It can overcome a series of disadvantages of the traditional hydraulic power transmission system. In addition, the paper introduces the operation principle of MRF power transmission, and researches the working performance and the fundamental factors that affect the properties of MRF by modeling and simulation. Finally, the paper explores theory and method of optimum design for MRF power transmission.

Abstract:

The aim of this interpretative, qualitative research study is to investigate affordances and constraints of dialogic pedagogy in the museums, as well as its broader contribution to society today. The background is my involvement in a Danish development project called ‘Museums and Cultural Institutions as Spaces for Citizenship,’ initiated by seven art museum educators in Copenhagen and supported by the Ministry of Culture. Denmark has a strong dialogic tradition dating back to Grundtvig’s belief in the power of ´the oral word’ to foster democratic ‘Bildung.’ Museum education, on the other hand, has a long tradition of monologic transmission. Still, a more participatory pedagogy has been gaining ground over many years. This study is based on the observations of three-hour-long teaching sessions in seven museums and has a Bakhtinian framework. While the overall analysis builds on the whole project, two cases are discussed in more detail. The overarching research question is how central aspects of dialogic pedagogy played out in an art museum context and its opportunities and challenges. The subquestions focus on three central Bakhtinian concepts: How did the educators facilitate multivoicedness during the short museum visits? What role did difference and disagreement play? What opportunities emerged for students to develop internally persuasive discourse? I have chosen these concepts because they are central in dialogism and combined them because they are closely connected in Bakhtin’s work. The final reflections open a wider perspective of how dialogic museum education may contribute to overarching functions of education: qualification, socialization, and subjectification. Key findings were that the museum educators’ transition from traditional to dialogic pedagogy was enhanced by their genuine interest in hearing students’ voices. They succeeded in engaging students in multivoiced dialogues but with a tendency towards harmonization rather than the exploration of diversity and difference. The practical aesthetic workshops offered unique opportunities for students to develop their internally persuasive word, i.e., by replacing authoritative interpretations of artworks with their own. Challenges experienced by the educators were, e.g., the dilemmas between preplanning and student choice and between disseminating their professional art knowledge and facilitating students’ meaning making and creativity. In contrast, students found the lack of workshop follow-up problematic. The article provides deeper insight into museums as an alternative pedagogical arena. Museum educators and non-museum classroom teachers may find it useful for cultivating greater dialogic interactions in respective learning contexts.

Abstract:

Purpose The purpose of this paper is to compare business cycle fluctuations in Ethiopia under interest rate and money growth rules. Design/methodology/approach In order to achieve this objective, the author constructs a medium-scale open economy dynamic stochastic general equilibrium (DSGE) model. The model features several nominal and real distortions including habit formation in consumption, price rigidity, deviation from purchasing power parity and imperfect capital mobility. The paper also distinguishes between liquidity-constrained and Ricardian households. The model parameters are calibrated for the Ethiopian economy based on data covering the period January 2000–April 2015. Findings The main result suggests that: the model economy with money growth rule is substantially less powerful or more muted for the amplification and transmission of exogenous shocks originating from government spending programs, monetary policy, technological progress and exchange rate movements. The responses of output to fiscal policy shocks are relatively stronger under autarky which appears to confirm the findings of Ilzetzki et al. (2013) who suggest bigger multipliers in self-sufficient, closed economies. With regard to positive productivity shock, however, the model with interest rate feedback rule generates a decline in output and an increase in inflation, which are at odds with conventional empirical regularities. Research limitations/implications The major implication is that a central bank regulating some measure of monetary stocks should not expect (fear) as much expansion (contraction) in output following currency devaluation (liquidity withdrawal) as a sister central bank that relies on an interest rate feedback rule. As emphasized by Mishra et al. (2010) the necessary conditions for stronger transmission of interest-rule-based monetary policy shocks are hardly existent in emerging and developing economies targeting monetary aggregates; hence the relatively weaker responses of output and inflation in the model economy with money growth rule. Monetary policy authorities need to be cautious when using DSGE models to analyze business cycle dynamics. Quite often, DSGE models tend to mimic the proverbial “crooked house” built to every man’s advise. Whenever additional modification is made to an existing baseline model, previously established regularities break down. For instance, this paper documented negative response of output to technology shock. Such contradictions are not uncommon. For example, Furlanetto (2006) and Ramayandi (2008) have also found similarly inconsistent responses to fiscal and productivity shocks, respectively. Originality/value Using DSGE models for research and teaching purposes is not common in developing economies. To the best of the author’s knowledge, only one other Ethiopian author did apply DSGE model to study business cycle fluctuation in Ethiopia albeit under the implausible assumption of perfect capital mobility and a central bank following interest rate rule. The contribution of this paper is that it departs from these two unrealistic assumptions by allowing international risk premium as a function of the net foreign asset position of the country and by applying money growth rule which closely mimics the behavior of central banks in low-income economies such as Ethiopia.

Abstract:

Magnetic resonance wireless power transmission technology is based on the phenomenon of resonant coupling to realize non-contact power transmission via near magnetic field. Based on the mutual coupling model of resonance system, the influence laws of system transmission parameters, such as coil coupling coefficients, load resistance, etc., on the transmission performance are theoretically studied in this paper. The research results shows that the power high-efficiency and high-quality transmission does not depend on the large coil loop coupling coefficient and the working frequencies of maximum power and maximum efficiency transmission do not coincide at most condition. Transmission systems with a high resonance frequency can produce high power and efficiency transmission over short distances. In addition, by increasing the coil diameter or wire diameter can improve the system quality factor, and optimize the energy transmission performance.

Abstract:

This paper reports on an action research study on curriculum design in an optional module at the Norwegian University of Science and Technology. There were two professors teaching their respective parts, henceforth termed “Part 1” and “Part 2”. Oral evaluations confirmed students’ satisfaction with teaching; however, failure rates had been an issue for years and was a concern to the professors who were wondering why. This study sets out to explore causes of poor academic achievement in order to launch targeted interventions. A major issue was students’ limited capabilities in dealing with conceptual and theoretical problems. This was partially explained by a mismatch between types of problems in the exercises compared with those at the final exam. The ensuing intervention included the redesign of tasks to improve alignment of course components as well as introducing a mid-term exam specifically addressing conceptual and theoretical themes. Failure rates dropped markedly in subsequent years due to students’ enhanced ability to cope with the broader spectrum of course requirements.

Abstract:

Power transmission (PT) projects are vital for the power sector. However, worldwide PT projects experience delay. There is an urgent need to understand the unique causes of delays in PT projects. This paper presents the first empirical study on causes of delays in PT projects via a comprehensive literature review. Based on this literature review, 63 potential delay factors are identified and divided into ten major groups. These include two new groups of delay attributes, comprising sector-specific factors (SSF) and general factors (GF), where SSF pertains solely to PT projects and GF contributes to minimizing the bias of project participants. A questionnaire survey of 311 PT stakeholders is conducted to determine the overall ranking of the delay factors using the relative importance index. The results indicate that SSF, GF, and external/unavoidable factors are the most critical groups of delay factors, with the top-ranked factors being right of way problems of transmission line (TL), frequent changes in TL routes, and accessibility to the TL tower locations. Finally, recommendations are made to help minimize time overruns in PT projects, as well as in other linear power and non-power construction projects in general.

Abstract:

Rotary ultrasonic applications are being widely used in machining hard and brittle materials. Conventional conducting ring used as power transmission part limits the ultrasonic applications from rotating at high speed. A high efficiency power transmission system is defined in this article to solve this problem. It consists of a contactless transformer, which was made up of two hollow copper coils, ultrasonic power supply and compensation capacitors. Four compensation methods are proposed and their properties are analyzed through simulations and experiments. The simulations show that S-S compensation is superior to others on the performance of transient and steady circuit parameters and the max transmit efficiency can reach about 97.2% when appropriate compensation method and capacitance are used. Rotary experiments show that speed has little effect on the property of the system.
