Multilevel Hybrid Cascade-Stack Inverter With Substantial Reduction In Switches Number And Power Losses, Mahdi Toopchi Khosroshahi, Ali Ajami, Ata Ollah Mokhberdoran, Mohammadreza Jannati Oskuee

Turkish Journal of Electrical Engineering and Computer Sciences

This paper proposes a multilevel hybrid cascade-stack (HCS) converter. Recently, different new topologies for cascade-type converters have been suggested with the goal of reducing switch number, loss, switch PIV, etc. Meanwhile, output voltage steps increase, and the number of switches is predominately reduced in the suggested inverter in comparison to conventional cascade converters. Additionally, a reduction in the number of on-state switches in the introduced topology causes power loss and voltage drop to decrease. Firstly, the fundamental parts of inverter configuration are described. Afterwards, symmetric and asymmetric converter types are discussed. Simulation and experimental results for 11- and 23-level symmetric …

Regulation Of Methane Gas Output From An Anaerobic Reactor System Using Moving Horizon $H_{\Infty }$ Control, Fatma Yildiz Taşcikaraoğlu, Şeref Naci̇ Engi̇n

Turkish Journal of Electrical Engineering and Computer Sciences

In this study, the moving horizon $\mathcal{H}_{\infty }$\textbf{ }control used for tracking a desired methane gas output from an anaerobic wastewater treatment reactor is compared with classical $\mathcal{H}_{\infty }$ control and a proportional-integral-derivative controller. The nonlinear system is first linearized around the set of equilibrium and operating points selected, and then the linear matrix inequalities required to comply with the constraints and guarantee the stability are constructed. Finally, the experimental results are obtained by implementing the control method in a MATLAB environment. It is concluded that moving horizon $\mathcal{H}_{\infty }$ control yields satisfactory results.

The Prime Tournaments $T$ With $\Mid\! W_{5}(T) \!\Mid = \Mid\! T \!\Mid -2$, Houmem Belkhechine, Imed Boudabbous, Kaouthar Hzami

Turkish Journal of Mathematics

We consider a tournament $T=(V, A)$. For $X\subseteq V$, the subtournament of $T$ induced by $X$ is $T[X] = (X, A \cap (X \times X))$. A module of $T$ is a subset $X$ of $V$ such that for $a, b\in X$ and $ x\in V\setminus X$, $(a,x)\in A$ if and only if $(b,x)\in A$. The trivial modules of $T$ are $\emptyset$, $\{x\}(x\in V)$, and $V$. A tournament is prime if all its modules are trivial. For $n\geq 2$, $W_{2n+1}$ denotes the unique prime tournament defined on $\{0,\dots,2n\}$ such that $W_{2n+1}[\{0,\dots,2n-1\}]$ is the usual total order. Given a prime tournament $T$, …

Parent-Teacher Interactions: Engaging With Parents And Carers, Michelle Ellis, Graeme Lock, Geoff Lummis Jan 2015

Parent-Teacher Interactions: Engaging With Parents And Carers, Michelle Ellis, Graeme Lock, Geoff Lummis

Australian Journal of Teacher Education

This study sought to identify factors that parents and teachers described as impacting on their interactions. Previous research indicated that student performance levels increase when parents and teachers work together; however, in practice, there are underlying tensions. The key findings revealed that the nature of parent-teacher interactions was either collaborative or non-collaborative, several activities underpinned these practices, and positive or less than satisfactory outcomes were afforded to students. Furthermore, parents and teachers had similar preferences on what practices made their interactions collaborative; however, they had different views (preferences) on what constituted non-collaborative practices. The findings from this research have implications …

From 'Following' To Going Beyond The Textbook: Inservice Indian Mathematics Teachers' Professional Development For Teaching Integers, Ruchi S. Kumar, Kalyansundaram Subramaniam Jan 2015

From 'Following' To Going Beyond The Textbook: Inservice Indian Mathematics Teachers' Professional Development For Teaching Integers, Ruchi S. Kumar, Kalyansundaram Subramaniam

Australian Journal of Teacher Education

Abstract :In this paper we describe four Indian in-service middle school mathematics teachers’ shifts in their roles with respect to the textbook. The shifts occurred through participation in collaborative investigation on the topic of integers in professional development meetings. Analysis of teachers’ talk in these meetings indicated a shift in teachers’ role from reliance on textbook to using the knowledge of integer meanings to establish the connections between contexts and representations. We claim that this change in role occurred as a result of teachers developing knowledge of important ideas and representations in the professional development setting and identifying themselves as …

The Disconnect Between Policy And Research: Examining The Research Into Full-Time K-12 Online Learning, Michael K. Barbour Jan 2015

The Disconnect Between Policy And Research: Examining The Research Into Full-Time K-12 Online Learning, Michael K. Barbour

Education Faculty Publications

While there has been some improvement in what is known about supplemental K-12 online learning, there continues to be a lack of evidence to guide the practice of full-time K-12 online learning. This paper concludes that despite considerable enthusiasm for full-time virtual education in some quarters, there is little high quality research to support the practice or call for expanding this form of virtual schools.

Fire-Sale Fdi? The Impact Of Financial Crises On Foreign Direct Investment, Olga B. Stoddard, Ilan Noy

Faculty Publications

We analyze the evolution of foreign direct investment (FDI) inflows to developing and emerging countries around financial crises. We empirically examine the Fire-Sale FDI hypothesis and describe the pattern of FDI inflows surrounding financial crises. We also add a more granular detail about the types of financial crises and their potentially differential effects on FDI. We distinguish between mergers and acquisitions(M&A) and greenfield investment, as well as between horizontal (tariff jumping) and vertical (integrating production stages) FDI. We find that financial crises have a strong negative effect on inward FDI in our sample. Crises are also shown to reduce the …

Toward A Practical Civic Piety: Mitt Romney, Barack Obama, And The Race For National Priest, Richard Benjamin Crosby Jan 2015

Toward A Practical Civic Piety: Mitt Romney, Barack Obama, And The Race For National Priest, Richard Benjamin Crosby

Faculty Publications

In 2008, two of the leading presidential candidates emerged from controversial, outsider religious groups—Mormonism and the black church tradition. Dogged by ongoing questions from the media, each candidate produced a high-profıle public address. In this article, I argue that Mitt Romney’s “Faith in America” and Barack Obama’s “A More Perfect Union” craft competing visions for American civic piety. Drawing on recent literature in the area of practical piety, I read the speeches as evidence that civic piety may be more than a subordinating, pragmatic agreement between church and state. It may instead be read as a spiritually substantive space of …

Answering Research Questions Without Calculating The Mean, Guillermo J. Campitelli Jan 2015

Answering Research Questions Without Calculating The Mean, Guillermo J. Campitelli

Research outputs 2014 to 2021

In an important theoretical article Speelman and McGann (2013) indicated that psychological researchers tend to use statistical procedures that involve calculating the mean of a variable in an uncritical manner. A typical procedure in psychological research consists of calculating the mean of some dependent variable in two or more samples and to present those means as summaries of the samples. The next step is to use some statistical technique (e.g., t -test, ANOVA) in order to be able to determine the probability of finding the observed differences between means in those samples given that the difference between the means of …
