PROBLEMATIKA DAN STRATEGI PENINGKATAN MUTU PENDIDIKAN TINGGI DI INDONESIA
Authors: Saepudin Asep
Published: September 2018

Problematikan dan peningkatan kualitas mutu bagi perguruan tinggi merupakan dua hal penting yang perlu diperhatikan. Kenyatan menunjukan bahwa selama ini perguruan tinggi tidak terlepas dari persoalan (problematika) yang berkenaan dengan tiga hal, yaitu: (1) masih rendahnya pemerataan dalam memperoleh pendidikan, (2) masih rendahnya kualitas dan relevansi pendidikan, dan (3) masih lemahnya manajemen pendidikan. Kondisi tersebut perlu segera diselesaikan melalui reformasi pendidikan yang mengarah kepada peningkatan kualitas mutu dengan pendekatan konsep manajemen mutu terpadu atau Total Quality Manajement (TQM). Walupun konsep tersebut pada mulanya dikembangkan dalam dunia bisnis dan industri, namun dapat diterapkan pula pada bidang pendidikan, khususnya di perguruan tinggi. Kendatipun demikian, berbeda dengan manajemen bisnis atau industri, penerapan Total Quality Manajement (TQM) dalam mencapai manajemen kualitas mutu di Perguruan Tinggi (management for quality in higer education institutions) lebih difokuskan pada pada dua hal, yaitu: Pertama, stimulasi dari koherensi proses belajar. Kedua, Analisis kebutuhan berbagai kelompok peserta didik. yakni mahasiswa sebagai peserta didik. Oleh karenanya orientasi terhadap peserta didik adalah kunci management for quality in higer education institutions.
O Instituto da Preclusão Lógica como Limitação do Direito à Repactuação de Preços nos Contratos Administrativos de Prestação de Serviços Continuados
Authors: Carneiro Maria Aurineide Moreira
Published: September 2018

Os contratos administrativos prevêem a possibilidade de alteração de preços para garantir a manutenção do equilíbrio econômico financeiro, assim considerado como a manutenção das condições comutativas estabelecidas entre as partes ao tempo da apresentação da proposta, para a manutenção da proporcionalidade entre o tamanho do encargo do contratado e a remuneração por parte da contratante. Entre as formas de se buscar a manutenção do equilíbrio financeiro dos contratos administrativos encontra-se a repactuação de preços, espécie do gênero reajuste dos contratos administrativos. O Tribunal de Contas da União – TCU e a Advocacia Geral da União – AGU difundiram entendimento segundo o qual o exercício do direito à repactuação de preços apresenta limitação temporal, por imposição do instituto da preclusão lógica, elemento limitativo de imposição doutrinária e jurisprudencial. O presente estudo busca, sem a pretensão de esgotar o tema, abordar a utilização da preclusão lógica nos contratos administrativos de contratação de serviços continuados, como medida limitativa ao exercício do direito dos contratados à repactuação, para reivindicação e recebimento de diferenças de valores devidas em razão de superveniência de Convenções Coletivas de Trabalho – CCT’s.
A Importância do Plano Plurianual Participativo na Gestão Pública
Authors: Ferreira Filho Wilson Rodrigues
Published: September 2018

A cada dia a sociedade brasileira vem ultrapassando antigos obstáculos no que tange à participação popular na administração da coisa pública, ganhando mais espaço nas decisões importantes dos governos, seja federal, estadual ou municipal. Como exemplo, temos as iniciativas dos três entes federados em implantarem em suas administrações o chamado Plano Plurianual Participativo (PPA-P), ideia já adotada em vários governos pelo País, que vem dando resultados positivos em busca de uma nova cara para a gestão pública. Neste trabalho busca-se demonstrar a importância do PPA Participativo Brasileiro, mostrando como a União, os Estados e os municípios brasileiros estão trabalhando esse processo com a sociedade, partindo da premissa de que a população e os demais segmentos sociais devem colaborar para a construção de uma gestão pública eficiente, que esteja mais próxima dos anseios da coletividade.

O Status Militar da Polícia Ostensiva nas Constituições Brasileiras, sob a Ótica da Proteção ao Pacto Federativo
Authors: Sousa José Kilderlan Nascimento de
Published: September 2018

Neste artigo, realiza-se uma análise crítica da inserção das polícias militares estaduais na Constituição Federal – de forma pioneira, em relação às demais forças policiais brasileiras – e do controle dessas forças militares realizado pela União, mediante o Exército Brasileiro. Faz-se ainda uma reflexão sobre a manutenção de seu status militar como imposição do governo central para um controle mais efetivo desses “exércitos estaduais”. Essa manutenção constitui fator de proteção do Pacto Federativo, principalmente para evitar que estados economicamente mais fortes possam representar uma ameaça à federação.
Reflexões sobre o Princípio da Proteção da Confiança Legítima no Direito Brasileiro
Authors: Santos Raimundo Nonato Silva , Romão Pablo Freire
Published: September 2018

O presente trabalho pretende realizar reflexões acerca do princípio da proteção da confiança legítima. Inicialmente, é realizada uma delimitação conceitual, bem como traçada a evolução histórica do instituto no Direito Brasileiro, para, em seguida, enquadrá-lo normativamente. Em relação aos resultados, constatou-se que o princípio da proteção da confiança representa a natureza subjetiva do princípio da segurança jurídica, possuindo, além de efeitos e conteúdos próprios, significação constitucional. Por meio de sua aplicação, percebe-se a viabilidade de manutenção de atos administrativos ilegais que, em virtude da presunção de legitimidade, tiveram seus efeitos prolongados no tempo. A título de conclusão, o princípio da proteção da confiança legítima representa a consagração de axiomas éticos no âmbito da Administração Pública, impedindo alterações abruptas das condutas estatais, notadamente daquelas que, além de gerarem solo fértil ao surgimento de bases de fidúcia, faz com que o exercício da confiança se dê por um logo período de tempo.
A Qualidade e a Agilidade do Controle Externo Dependem Diretamente do Desempenho de seus Servidores
Authors: Macêdo Evilânia
Published: September 2018

Com a globalização e o acelerado avanço tecnológico surgiram novos cenários de gestão e, em particular, na área de Recursos Humanos, cuja função foi elevada à condição de natureza estratégica nos últimos 20 anos. Passamos do RH tradicional à Gestão de Pessoas. Do operacional ao estratégico. De uma arquitetura burocrática e rotineira para um modelo estratégico de alinhamento do desempenho individual com as estratégias organizacionais. Esse novo cenário, hoje denominado Gestão de Pessoas, exige uma reflexão mais aprofundada acerca dessa realidade ainda pouco conhecida no âmbito organizacional dos Tribunais de Contas. Então, o objetivo deste artigo é discutir acerca das políticas e das práticas de Gestão de Pessoas desenvolvidas por essas instituições na busca de um bom desempenho organizacional, que garanta a qualidade e a agilidade dos serviços por elas prestados à sociedade. Para tanto, optou-se por apresentar inicialmente a evolução histórica do RH, contextualizada dentro da Teoria Geral da Administração, para, em seguida, descrever o cenário atual dessa área – Gestão de Pessoas – onde há forte tendência de que as organizações governamentais, em especial, neste artigo, os Tribunais de Contas, incorporem cada vez mais em suas práticas cotidianas os conceitos e tendências há muito utilizados pelas organizações privadas. Por fim, falamos do ambiente multigeracional que hoje caracteriza o contexto interno dessas instituições de contas, destacando o papel da ATRICON e do IRB nesse processo.
Política de Integridade Pública em Licitações
Authors: Magalhães João Marcelo Rego
Published: September 2018

A partir de uma análise crítica da Lei nº 8.666, de 21 de junho de 1993 (Lei Geral de Licitações), dos pronunciamentos oriundos dos órgãos de controle externo, das regras sobre sustentabilidade ambiental, das legislações que garantem o acesso à informação, regulam o conflito de interesses e vedam a prática de atos de corrupção contra o poder público, bem como das orientações fixadas pelo órgão de assessoramento jurídico competente, é possível identificar um conjunto de princípios e regras a que estão obrigados a cumprir os agentes públicos em suas relações com a Administração Pública, em atenção à legitimidade, legalidade e probidade dos procedimentos licitatórios. Esse arcabouço de normas, que deve ser observando antes mesmo de garantidos os direitos dos particulares que almejam contratar com o Estado, pode ser denominado de “Política de Integridade Pública em Licitações”.

A Fonte de custeio das agências reguladoras
Authors: Gomes Ana Paula de Oliveira
Published: September 2018

Em tese, a missão institucional das agências reguladoras é cumprir as políticas determinadas pelo Estado, harmonizando os interesses dos agentes envolvidos em prol do bem comum. Para tanto, necessitam de autonomia, o que “legitima” arrecadação da taxa de regulação obtida diretamente dos prestadores de serviço. A matéria apresenta entendimentos divergentes quanto à natureza dessa taxa, o que justifica a relevância do enfrentamento da questão. Objetivo geral: analisar juridicamente essa receita pública a partir do modelo regulatório brasileiro. A pesquisa desenvolve estudo bibliográfico, eminentemente lógico-descritivo.
Controle Social das Políticas Públicas no Brasil
Authors: Silva Jacqueline Maria Cavalcante da
Published: September 2018

O controle social das políticas públicas no Brasil é o foco deste artigo. Seu objetivo principal foi investigar se o controle social é um instrumento com capacidade para induzir o Estado a otimizar a execução das políticas públicas em busca da efetividade dos fins constitucionais. O enfoque metodológico quanto à natureza é qualitativo, quanto ao tipo bibliográfico, quanto ao fim explicativo e, relativamente à utilização dos resultados, pura. Conclui-se que o controle social, conforme exercido até então, não demonstra capacidade plena para uma efetiva interferência nas ações do Estado concernentes às políticas públicas, sendo essa situação decorrente das resistências impostas por parte de governos e políticos, situação que é favorecida pelas limitações dos cidadãos.

Valsartan and candesartan can inhibit deteriorating effects of angiotensin II on coronary endothelial function
Authors: Seeger Harald , Lippert Caroline , Wallwiener Diethelm , Mueck Alfred O
Published: September 2018

The angiotensin II (Ang II) AT1-receptor antagonists, valsartan and candesartan, were compared with regard to their effect on Ang II-mediated changes in parameters of coronary endothelial function. Ang II (10 µM) induced increased concentrations of the vasoconstrictor endothelin, the procoagulatory substance plasminogen-activator-inhibitor-1 (PAI-1) and the precursor of the matrix-metalloproteinase 1 (MMP-1) in endothelial cell cultures from human coronary arteries. These increases were completely prevented by the addition of 10 µM valsartan or candesartan and partially by the addition of lower concentrations of these drugs, i.e. 1 µM and 0.1 µM. No significant difference between the effect of the two AT1-receptor antagonists was observed.

These results suggest that AT1-receptor antagonists not only can reduce blood pressure by blocking the action of Ang II, but might also contribute to the prevention of atherogenesis and plaque instability.
Optimization of Axial Magnetic Bearing Actuators for Dynamic Performance
Authors: Spece Henry , Fittro Roger , Knospe Carl
Published: September 2018

Axial magnetic bearing actuators often lack the bandwidth necessary to achieve the desired closed loop performance due to their nonlaminated construction. Since bandwidth can be directly related to actuator material and geometric properties, an opportunity exists to improve closed loop performance through the optimization of these properties. This prospect is exploited herein, both to demonstrate the improvements that can be obtained and to illustrate the relationship between various parameters and dynamic performance. For the latter, Pareto-optimal curves are generated exploring the influence that disk outer radius, peak force, axial gap, and magnetic permeability have upon actuator bandwidth.

Published: September 2018

This study aimed to evaluate the effect of dietary supplementation with supra-nutritional levels of vitamins A and E on fertility and productivity traits of Ross-308 broiler breeder hens during the late production phase. The trial was conducted for nine weeks, from 61 to 69 weeks of age, and designed to test four levels of vitamin A (100, 125, 150 and 200% above the Ross catalogue recommendations) and four levels of vitamin E (100, 200, 300 and 400% above Ross catalogue instructions), maintaining constant the other rearing conditions. Vitamins were combined in 16 treatments, with four replicates per treatment each including seven females, and one rooster broiler was used in every two replicates. A total of 448 hens and 32 roosters were used in the experiment. Fertility parameters were weekly evaluated. According to the results, egg-related parameters (number and weight of eggs, non-conform eggs and hatchability) were not affected by treatment, but dietary treatments increased and extended the hens’ productivity for an additional six weeks in most experimental groups. The chick-related parameters (number and weight of produced chicks) and chick yield differed significantly among groups (p < 0.05). The best economic index was found in birds fed basal-diet plus 100% of vitamin A and 200% of vitamin E. In conclusion, the present study showed that a combination of dietary supra-nutritional levels of vitamins A and E allowed to extend the laying period and to reduce the decline of fertility in older breeder hens at the end of the laying stage; in particular, among the 16 tested treatments, feeding of supra-nutritional level of 100% vitamin A and 200% vitamin E lead to the best results.

A New Hybrid Approach for Wind Speed Forecasting Applying Support Vector Machine with Ensemble Empirical Mode Decomposition and Cuckoo Search Algorithm
Authors: Liu Tongxiang , Liu Shenzhong , Heng Jiani , Gao Yuyang
Published: September 2018

Wind speed forecasting plays a crucial role in improving the efficiency of wind farms, and increases the competitive advantage of wind power in the global electricity market. Many forecasting models have been proposed, aiming to enhance the forecast performance. However, some traditional models used in our experiment have the drawback of ignoring the importance of data preprocessing and the necessity of parameter optimization, which often results in poor forecasting performance. Therefore, in order to achieve a more satisfying performance in forecasting wind speed data, a new short-term wind speed forecasting method which consists of Ensemble Empirical Mode Decomposition (EEMD) for data preprocessing, and the Support Vector Machine (SVM)—whose key parameters are optimized by the Cuckoo Search Algorithm (CSO)—is developed in this paper. This method avoids the shortcomings of some traditional models and effectively enhances the forecasting ability. To test the prediction ability of the proposed model, 10 min wind speed data from wind farms in Shandong Province, China, are used for conducting experiments. The experimental results indicate that the proposed model cannot only improve the forecasting accuracy, but can also be an effective tool in assisting the management of wind power plants.
Effect of Different Proteases on the Degree of Hydrolysis and Angiotensin I-Converting Enzyme-Inhibitory Activity in Goat and Cow Milk
Authors: Shu Guowei , Huang Jie , Bao Chunju , Meng Jiangpeng , Chen He , Cao Jili
Published: September 2018

Angiotensin I-converting enzyme (ACE) peptides are bioactive peptides that have important value in terms of research and application in the prevention and treatment of hypertension. While widespread literature is concentrated on casein or whey protein for production of ACE-inhibitory peptides, relatively little information is available on selecting the proper proteases to hydrolyze the protein. In this study, skimmed cow and goat milk were hydrolyzed by four commercial proteases, including alkaline protease, trypsin, bromelain, and papain. Angiotensin I-converting enzyme-inhibitory peptides and degree of hydrolysis (DH) of hydrolysates were measured. Moreover, we compared the difference in ACE-inhibitory activity between cow and goat milk. The results indicated that the DH increased with the increase in hydrolysis time. The alkaline protease-treated hydrolysates exhibited the highest DH value and ACE-inhibitory activity. Additionally, the ACE-inhibitory activity of hydrolysates from goat milk was higher than that of cow milk-derived hydrolysates. Therefore, goat milk is a good source to obtain bioactive peptides with ACE-inhibitory activity, as compared with cow milk. A proper enzyme to produce ACE-inhibitory peptides is important for the development of functional milk products and will provide the theoretical basis for industrial production.
Faecal Microbial Markers and Psychobiological Disorders in Subjects with Morbid Obesity. A Cross-Sectional Study
Authors: Farup Per G , Valeur Jørgen
Published: September 2018

Morbidly obese subjects have a high prevalence of comorbidity and gut microbial dysbiosis, and are thus suitable for the study of gut-brain interactions. The aim was to study the associations between the faecal microbiota’s composition and function and psychobiological comorbidity in subjects with BMI > 40 kg/m2 or >35 kg/m2 with obesity-related complications. The faecal microbiota was assessed with GA-Map dysbiosis test ™ (Genetic Analysis, Oslo Norway) and reported as dysbiosis (yes/no) and degree of dysbiosis, and the relative abundance of 39 bacteria. The microbiota’s function was assessed by measuring the absolute and relative amount of faecal short chain fatty acids. Associations were made with well-being, mental distress, fatigue, food intolerance, musculoskeletal pain, irritable bowel syndrome, and degree of abdominal complaints. One hundred and two subjects were included. The results confirmed the high prevalence of comorbidity and dysbiosis (62/102; 61%) and showed a high prevalence of significant associations (41/427; 10%) between the microbiota’s composition and function and the psychobiological disorders. The abundant, but in part divergent, associations supported the close gut-brain interaction but revealed no clear-cut and straightforward communication pathways. On the contrary, the study illustrates the complexity of gut-brain interactions.
Elastic and Dielectric Evaluation of the Piezoelectric Response of Ferroelectrics Using Unpoled Ceramics
Authors: Cordero Francesco
Published: September 2018

The evaluation of the piezoelectric properties of ferroelectric ceramics generally has a high level of uncertainty, due to incomplete poling, porosity, domain wall clamping and other effects. In addition, the poling process is often difficult and dangerous, due to the risk of breaking or damaging the sample. A method is described for the evaluation of the potential intrinsic piezoelectric response that a ceramic would have after full poling, without poling it. The method relies on the fact that any material undergoes an elastic softening below the ferroelectric transition temperature, whose magnitude can be expressed in terms of the intrinsic piezoelectric and dielectric coefficients of the material. Such a softening is equivalent to an electromechanical coupling factor averaged over all the components, due to the unpoled state of the sample, and can be deduced from a single temperature scan of an elastic modulus of a ceramic sample, spanning the ferroelectric and paraelectric states. The strengths, limits and possible applications of the method are discussed.
Responses to Intermittent Light Stimulation Late in the Night Phase Before Dawn
Authors: Kaladchibachi Sevag , Negelspach David C. , Fernandez Fabian
Published: September 2018

The circadian clock is comprised of two oscillators that independently track sunset (evening) and sunrise (morning), though little is known about how light responses differ in each. Here, we quantified the morning oscillator’s responses to 19 separate pulse trains, collecting observations from over 1300 Drosophila at ZT23. Our results show that the advances in activity onset produced by these protocols depended on the tempo of light administration even when total exposure was conserved across a 15-min window. Moreover, patterns of stimulation previously shown to optimize the evening oscillator’s delay resetting at ZT13 (an hour after dusk) were equally effective for the M oscillator at ZT23 (an hour before dawn), though the morning oscillator was by comparison more photosensitive and could benefit from a greater number of fractionation strategies that better converted light into phase-shifting drive. These data continue to build the case that the reading frames for the pacemaker’s time-of-day estimates at dusk and dawn are not uniform and suggest that the “photologic” for the evening versus morning oscillator’s resetting might be dissociable.
Dynamic Behavior of Dilute Bentonite Suspensions under Different Chemical Conditions Studied via Magnetic Resonance Imaging Velocimetry
Authors: Chernoburova Olga , Jenny Mathieu , Kiesgen De Richter Sébastien , Ferrari Maude , Otsuki Akira
Published: September 2018

This study investigates dilute aqueous suspensions of bentonite particles using magnetic resonance imaging (MRI) velocimetry. Four different chemical conditions are tested to investigate the influence of pH and type of monovalent electrolyte on the local rheological behavior of bentonite suspensions. The results indicate the shear banding in a dilute suspension of 0.1 vol.% solid due to the formation of a continuous three-dimensional particle network under a certain chemical environment (i.e., pH 4 in 1 × 10−2 M KNO3). This network is responsible for the existence of the yield stress in that dilute suspension. Structural changes induced by modification of suspensions’ chemistry are examined via scanning electron microscopy. A previously established method based on processing the torques acquired via conventional rheometric measurement is also applied as an alternative way to recover local flow information. Within the shear rate range covered by our MRI velocimetry, the results of both methods show good agreement. This study suggests that the existence of a master curve (or global flow curve) for dilute suspensions is dependent on the bentonite particle organization, which is influenced by the suspension chemistry and the previous flow history.
GoCJ: Google Cloud Jobs Dataset for Distributed and Cloud Computing Infrastructures
Authors: Hussain Altaf , Aleem Muhammad
Published: September 2018

Developers of resource-allocation and scheduling algorithms share test datasets (i.e., benchmarks) to enable others to compare the performance of newly developed algorithms. However, mostly it is hard to acquire real cloud datasets due to the users’ data confidentiality issues and policies maintained by Cloud Service Providers (CSP). Accessibility of large-scale test datasets, depicting the realistic high-performance computing requirements of cloud users, is very limited. Therefore, the publicly available real cloud dataset will significantly encourage other researchers to compare and benchmark their applications using an open-source benchmark. To meet these objectives, the contemporary state of the art has been scrutinized to explore a real workload behavior in Google cluster traces. Starting from smaller- to moderate-size cloud computing infrastructures, the dataset generation process is demonstrated using the Monte Carlo simulation method to produce a Google Cloud Jobs (GoCJ) dataset based on the analysis of Google cluster traces. With this article, the dataset is made publicly available to enable other researchers in the field to investigate and benchmark their scheduling and resource-allocation schemes for the cloud. The GoCJ dataset is archived and available on the Mendeley Data repository.

The deployment of unmanned aerial vehicles (i.e., drones) in military and police operations implies that drones can provide footage that is of sufficient quality to enable the recognition of strategic targets, criminal suspects, and missing persons. On the contrary, evidence from Cognitive Psychology suggests that such identity judgements by humans are already difficult under ideal conditions, and are even more challenging with drone surveillance footage. In this review, we outline the psychological literature on person identification for readers who are interested in the real-world application of drones. We specifically focus on factors that are likely to affect identification performance from drone-recorded footage, such as image quality, and additional person-related information from the body and gait. Based on this work, we suggest that person identification from drones is likely to be very challenging indeed, and that performance in laboratory settings is still very likely to underestimate the difficulty of this task in real-world settings.

Models can be simple for different reasons: because they yield a simple and computationally efficient interpretation of a generic dataset (e.g., in terms of pairwise dependencies)—as in statistical learning—or because they capture the laws of a specific phenomenon—as e.g., in physics—leading to non-trivial falsifiable predictions. In information theory, the simplicity of a model is quantified by the stochastic complexity, which measures the number of bits needed to encode its parameters. In order to understand how simple models look like, we study the stochastic complexity of spin models with interactions of arbitrary order. We show that bijections within the space of possible interactions preserve the stochastic complexity, which allows to partition the space of all models into equivalence classes. We thus found that the simplicity of a model is not determined by the order of the interactions, but rather by their mutual arrangements. Models where statistical dependencies are localized on non-overlapping groups of few variables are simple, affording predictions on independencies that are easy to falsify. On the contrary, fully connected pairwise models, which are often used in statistical learning, appear to be highly complex, because of their extended set of interactions, and they are hard to falsify.
Second Law and Non-Equilibrium Entropy of Schottky Systems—Doubts and Verification–
Authors: Muschik Wolfgang
Published: September 2018

Meixner’s historical remark in 1969 “... it can be shown that the concept of entropy in the absence of equilibrium is in fact not only questionable but that it cannot even be defined....” is investigated from today’s insight. Several statements—such as the three laws of phenomenological thermodynamics, the embedding theorem and the adiabatical uniqueness—are used to get rid of non-equilibrium entropy as a primitive concept. In this framework, Clausius inequality of open systems can be derived by use of the defining inequalities which establish the non-equilibrium quantities contact temperature and non-equilibrium molar entropy which allow to describe the interaction between the Schottky system and its controlling equilibrium environment.
Maximum-Entropy Tools for Economic Fitness and Complexity

Published: September 2018

The concepts of economic fitness and complexity, based on iterative and interdependent definitions of the quality of exporting countries and exported products, have led to novel insights into the dynamics of production and trade. A key step in the calculation of these quantities is the preliminary identification of statistically relevant country-product pairs.In this paper, we propose a method that could improve the current practice of filtering based on the revealed comparative advantage, by employing the maximum-entropy principle to construct an unbiased link weight probability distribution that, unlike the traditional thresholding method, allows for the statistical assessment of empirical trade volumes. The result is an adjusted geometric distribution for trade links that refines the revealed comparative advantage approach. This allows us to define the statistical significance of each trade link weight, leading to statistically supported trade link filtering decisions. Using this statistically justified filtering method, we have obtained results that are similar in nature to those that were found without this method, even though there are significant deviations in the details. In addition, the statistical information thus obtained on each trade link allows us to perform a spectral analysis of the export portfolio of individual economies.
Teachers as Learners: The Impact of Teachers’ Morphological Awareness on Vocabulary Instruction
Authors: Newton Joanna
Published: September 2018

Academic vocabulary knowledge is central to reading and academic achievement. Largely based in the lexicons of Latin and Greek, academic vocabulary comprises morphemic structures. Many teachers devote little time to focused instruction in this area because they may lack pertinent morphological and pedagogical knowledge. This article reports findings from a broader three-year longitudinal qualitative case study that explored the experiences of three elementary teachers who engaged in professional development that included study of the morphemic features of academic vocabulary and instructional techniques. This article describes changes teachers made to practice because of their deeper understanding of Latin and Greek morphology and how to teach it. Data sources included in-depth and semistructured interviews, direct observations of classroom practice, and analysis of instructional artifacts. Data analysis revealed that all three participants moved from teacher-centered, definitional approaches towards instruction that was student-centered and focused on developing metalinguistic awareness. Instructional shifts reflected participants’ new understandings about metalinguistic awareness, student-directed problem-solving, and collaborative talk in vocabulary learning. Instructional shifts address metalinguistic awareness, morphology, word consciousness, and Spanish–English cognate instruction—areas that may be overlooked in many classrooms.
Exploring the Limits of Floating-Point Resolution for Hardware-In-the-Loop Implemented with FPGAs
Authors: Sanchez Alberto , Todorovich Elías , De Castro Angel
Published: September 2018

As the performance of digital devices is improving, Hardware-In-the-Loop (HIL) techniques are being increasingly used. HIL systems are frequently implemented using FPGAs (Field Programmable Gate Array) as they allow faster calculations and therefore smaller simulation steps. As the simulation step is reduced, the incremental values for the state variables are reduced proportionally, increasing the difference between the current value of the state variable and its increments. This difference can lead to numerical resolution issues when both magnitudes cannot be stored simultaneously in the state variable. FPGA-based HIL systems generally use 32-bit floating-point due to hardware and timing restrictions but they may suffer from these resolution problems. This paper explores the limits of 32-bit floating-point arithmetics in the context of hardware-in-the-loop systems, and how a larger format can be used to avoid resolution problems. The consequences in terms of hardware resources and running frequency are also explored. Although the conclusions reached in this work can be applied to any digital device, they can be directly used in the field of FPGAs, where the designer can easily use custom floating-point arithmetics.
A Novel Approach to Investigating Transport of Lost Circulation Materials in Rough Fracture
Authors: Feng Yi , Li Gao , Meng Yingfeng , Guo Boyun
Published: September 2018

The drilling fluid loss or lost circulation via fractures is one of the critical engineering problems in the development of deep oil and gas resources. The conventional treatment is to introduce granular lost circulation material (LCM) into the drilling fluid system to plug fractures. In this work, a method incorporating the fracture surface scanning technique and coupled Computational Fluid Dynamics-Discrete Element Method (CFD-DEM) numerical simulation is proposed for the first time to investigate how the LCM particles plug rough fractures. The rough fracture model is built utilizing a high resolution and high precision measurement system. The LCM particle transport and plugging process in rough fractures are captured in the CFD-DEM numerical simulations. The results show that the local fracture aperture has a significant influence on LCM particle transport and the distribution of the plugging zone. The drilling fluid loss rate will decrease, and the drilling fluid pressure will redistribute during the accumulation of LCM particles in the fracture. The fracture plugging efficiency of nonspherical LCM is improved as a result of formation of multi-particle bridges. This study provides a novel approach and important theoretical guidance to the investigation of LCM particle transport in rough fractures.
Thermal and Energy Management Based on Bimodal Airflow-Temperature Sensing and Reinforcement Learning

Published: September 2018

Multi-physical field sensing and machine learning have drawn great attention in various fields such as sensor networks, robotics, energy devices, smart buildings, intelligent system and so on. In this paper, we present a novel efficient method for thermal and energy management based on bimodal airflow-temperature sensing and reinforcement learning, which expedites an exploration process by self-learning and adjusts action policy only through actuators interacting with the environment, being free of the controlled object model and priori experiences. In general, training of reinforcement learning requires a large amount of data iterations, which takes a long time and is not suitable for real-time control. Here, we propose an approach to speed up the learning process by indicating the action adjustment direction. We adopt tailor-designed bimodal sensors to simultaneously detect airflow and temperature field, which provides comprehensive information for reinforcement learning. The proposed thermal and energy management incorporates bimodal parametric sensing with an improved actor-critic algorithm to realize self-learning control. Experiments of thermal and energy management in a multi-module integrated system validate the effectiveness of the proposed methodology, which demonstrate high efficiency, fast response, and good robustness in various control scenarios. The proposed methodology can be widely applied to thermal and energy management of diverse integrated systems.
