Authors: Kartini Indriana
Published: November 2018

Abstrak Deklarasi Panmunjom yang ditandatangani oleh dua pemimpin Korea, Moon Jae-in dari Korea Selatan dan Kim Jong-un dari Korea Utara menandai era baru dalam perdamaian di Semenanjung Korea. Meskipun sikap skeptis akan implikasi positif bermunculan baik di dalam negeri maupun dunia internasional, namun komitmen dua negara Korea untuk mengakhiri perang patut diapresiasi oleh komunitas internasional. Tulisan ini menganalisis bagaimana Deklarasi Panmunjom berpengaruh terhadap keamanan regional dan internasional serta bagaimana prospek perdamaian dan unifikasi Korea pasca perjanjan Panmunjom. Berdasarkan analisis melalui pendekatan kualitatif, dapat disimpulkan bahwa meskipun terdapat beberapa persamaan antara Pertemuan Tingkat Tinggi Panmunjom dengan Pertemuan Tingkat Tinggi sebelumnya di tahun 2000 dan 2007, namun yang perlu digarisbawahi adalah kenyataan bahwa kedua negara Korea masih memiliki keinginan untuk menciptakan rezim perdamaian. Meskipun dalam mewujudkan hal tersebut masih diperlukan keterlibatan dua negara sekutu masing-masing negara Korea, yakni AS dan Cina. Kata Kunci : Deklarasi Panmunjom, perdamaian Korea, Korea Selatan, Korea Utara, Moon Jae-in, Kim Jog-un

Published: November 2018

A demanda por serviços de transporte em todo o mundo é um fenômeno que cresce à medida em que o processo de urbanização avança. No entanto, o excessivo uso de veículos acentua os problemas relacionados às entregas de última milha e à emissão de poluentes atmosféricos locais. O objetivo deste estudo é avaliar a sustentabilidade alcançada por meio da utilização de triciclos elétricos na distribuição postal na cidade do Rio de Janeiro. Identificou-se a redução de 27,86% do custo total de transportes. Ademais, observou-se reduções mensais de emissões de poluentes atmosféricos por rota de 10,11 g de CO; 32,78 g de NOX; 0,02 g de RCHO; 0,7 g de NMHC e 0,33 g de MP, enquanto que as reduções mensais de GEE por rota foram de 21,01 kg de CO2eq. Com relação aos aspectos sociais, a frequência cardíaca mostrou-se constante durante toda a operação, enquanto, na operação de distribuição tradicional intermodal, verificou-se uma maior variação durante a operação de entrega.
Uma análise empírica da padronização de frota de companhias aéreas e os efeitos de fatores operacionais
Authors: Narcizo Rodolfo Romboli , Oliveira Alessandro Vinicius Marques de
Published: November 2018

O presente trabalho desenvolve um modelo econométrico para avaliar alguns dos fatores determinantes das estratégias de padronização de frota de companhias aéreas. Considera-se a padronização em nível de modelo de aeronave, com controles dos efeitos da padronização de fabricante e de família dos equipamentos de voo. O modelo empírico foi estimado com dados do transporte aéreo brasileiro e utiliza diversas variáveis operacionais, como tamanho e idade médios da frota, fluxo de passageiros por voo e número de destinos servidos. O efeito de fatores de custos operacionais e de demanda são também incorporados ao modelo. Os resultados apontam para uma tendência à maior padronização de frota no Brasil. Entretanto, aumentos nos custos com combustível podem atenuar essa tendência, por induzir uma busca por aeronaves com tecnologia mais avançada e menor consumo energético. Os resultados da pesquisa possuem implicações de políticas corporativas e públicas visando ao estímulo da gestão eficiente e sustentável da frota das companhias aéreas no país ao longo dos próximos anos.
Calibração do modelo de aceitação de brechas em interseções urbanas com o microssimulador de tráfego VISSIM
Authors: Araújo Alessandro Macêdo de , Castro Neto Manoel Mendonça de
Published: November 2018

Este artigo tem como objetivo principal propor um método para a modelagem do processo de aceitação de brechas em interseções urbanas não semaforizadas utilizando o microssimulador VISSIM. O método proposto tem como medida-alvo o tempo que o motorista leva no processo de avaliação das brechas, ou seja, o tempo de espera enquanto está na primeira posição da fila. O c2 da aderência entre as distribuições dos tempos de espera (simulados e observados) e a diferença entre as médias foram utilizados na estimação da brecha crítica. O método foi aplicado em uma interseção da cidade de Fortaleza. Os resultados indicaram valores levemente diferentes da brecha crítica entre os movimentos de conversão. O segundo objetivo deste trabalho é comparar o método proposto com o método de calibração mais convencional, no qual a medida-alvo é uma medida de desempenho do tráfego, como o tamanho médio da fila. O método proposto apresentou melhores resultados.
Influência do modo de aplicação de carga nas propriedades de fratura de uma mistura asfáltica de agregados finos
Authors: Vargas Gustavo Adolfo Badilla , Oliveira Alex Duarte , Aragão Francisco Thiago Sacramento
Published: November 2018

Entre os diferentes modos de dano que comprometem a vida útil de misturas asfálticas, o trincamento é, provavelmente, um dos mais complexos e de difícil caracterização, uma vez que a resistência à fratura destes materiais é altamente dependente da temperatura e das condições de carregamento. Neste estudo investigou-se a influência das condições de carregamento sobre os parâmetros de fratura de uma mistura asfáltica de agregados finos, determinados a partir de simulações de ensaios de flexão em semicírculos (semi-circular bending - SCB). As simulações de SCB foram realizadas por meio do método dos elementos finitos e do modelo bilinear de zona coesiva, considerando apenas o modo I de fratura e três diferentes formas de carregamento. Os resultados obtidos (energia de fratura, resistência coesiva e curvas Força-CTOD) demonstraram que a forma de representar o carregamento exerce influência significativa sobre os parâmetros de fratura e, consequentemente, sobre a aplicabilidade deste tipo de procedimento numérico-experimental.

Published: November 2018

Este trabalho propõe uma análise desagregada de escolhas de destinos para viagens intermunicipais, por meio da aplicação de algoritmos de Aprendizagem de Máquinas - AM (Classification And Regression Tree - CART e Algoritmos Genéticos - AG). Foi utilizada uma Pesquisa OD, realizada pelo Centro de Estudos de Transportes e Meio Ambiente (UFBA), em 2012/2013 em onze municípios do estado da Bahia. Foi realizada a calibração de um Modelo Logit Multinomial a partir do algoritmo AG, trazendo a vantagem de associação das escolhas dos destinos a valores de coeficientes estimados das funções utilidade aleatórias, sem os problemas relativos à calibração dos modelos logit tradicionais, tais como erros identicamente distribuídos, seguindo a distribuição de Gumbel. O desempenho de cada algoritmo de AM foi comparado à abordagem tradicional (modelo gravitacional).  Os resultados evidenciaram que os algoritmos de AM apresentaram melhores previsões para a escolha de destinos, sendo que o AG apresentou vantagens na obtenção dos parâmetros associados às variáveis independentes. A principal conclusão é que tais algoritmos podem ser aplicados na modelagem de distribuição de viagens, incorporando o efeito das variáveis desagregadas, sem suposições matemáticas rigorosas contidas no ajuste de modelos tradicionais desagregados.

Published: November 2018

O microscópio de força atômica (AFM) tem sido usado para a caracterização microestrutural de ligantes asfálticos, a partir da identificação das suas frações constituintes. Adicionalmente, estudos mais recentes têm determinado propriedades mecânicas dos componentes dos ligantes, tais como fluência e módulo de relaxação, a partir de ensaios de indentação no AFM. No entanto, o processo de preparação das amostras usadas nestes ensaios geralmente não é descrito detalhadamente na literatura. Este trabalho tem o objetivo de avaliar diferentes métodos de preparação de amostras, empregando imagens topográficas usadas para caracterizações microestruturais. Para tal, microestruturas de um ligante obtidas de amostras preparadas usando diferentes métodos foram avaliadas e os resultados contribuíram para identificar o processo de preparação mais otimizado.

Authors: Medeiros Adalice Flavia Duarte de , Pimentel Roberto Leal , Melo Ricardo Almeida de
Published: November 2018

A utilização de barreiras acústicas é uma das medidas empregadas para minimizar o impacto gerado pelo ruído, pois é possível produzir uma atenuação no nível sonoro por meio da restrição à passagem do som diretamente da fonte para o receptor. As passagens inferiores em rodovias vêm sendo usadas para evitar cruzamentos em nível entre as vias. Pressupõe-se que esse desnível pode funcionar como uma barreira acústica contribuindo com a redução do ruído nas áreas circunvizinhas, com a vantagem de possuir pouco impacto visual. Neste artigo, analisou-se a passagem inferior construída na BR-230 com o objetivo de quantificar o efeito benéfico da mesma em relação a redução do ruído emitido. Medições de ruído foram realizadas na área urbana adjacente a esta passagem e, com os resultados obtidos, foram feitas correlações com expressões do modelo CoRTN para estimativa do ruído. Verificou-se, por meio comparativo, os benefícios que a passagem inferior disporia como solução acústica. Como resultado, obteve-se uma redução média de 11,8 dB(A), constituindo uma atenuação expressiva no nível de ruído para os pontos na região de sombra acústica.

Authors: Martins Marcel Carlos da Mata , Rodrigues da Silva Antônio Nélson
Published: November 2018

O objetivo deste estudo é desenvolver uma estratégia de avaliação da resiliência da mobilidade urbana, baseada na suposição de que modos motorizados não estariam disponíveis. Portanto, apenas os modos a pé e bicicleta foram considerados para este exercício teórico. As viagens foram inicialmente classificadas em dois grupos, de acordo com sua adaptabilidade ou transformabilidade, sendo as do primeiro grupo consideradas resilientes. Uma terceira categoria teve que ser introduzida para representar outro conjunto de viagens resilientes. Estas são as viagens excepcionais, isto é, viagens a pé ou de bicicleta que são mais longas do que as Distâncias Máximas Possíveis (DMP) definidas para avaliação da resiliência. O cenário mais pessimista (0 km) mostrou uma resiliência de 40,4%, e a resiliência máxima (100%) foi atingida com 12,5 km. Foi possível então, ajustar uma curva teórica para representar a variação da resiliência. Os resultados também revelaram um padrão para cada segmento de resiliência devido à forma da cidade

Published: November 2018

No intuito de contribuir com as discussões acerca da qualidade dos sistemas de transporte no município do Rio de Janeiro, o presente artigo investiga a eficiência de 24 das suas mais relevantes Regiões Administrativas em função da mobilidade. Essa investigação realiza-se por meio da Análise Envoltória de Dados (DEA), a qual estima a eficiência padrão de cada região, e por meio da Avaliação Cruzada, que ranqueia essas eficiências, bem como baseia-se no desempenho de dois indicadores: um de avaliação da eficiência social e outro de eficiência econômica das regiões. Esses indicadores mostram desempenho similar na DEA e bem diferentes na Avaliação Cruzada, evidenciando a discrepância das duas abordagens. Algumas regiões apresentam resultados discordantes (alta eficiência na DEA e baixa na Avaliação Cruzada), como Portuária e Realengo, e outras apresentam resultados equivalentes, como Centro, com alta eficiência, e Santa Cruz, com baixa, tanto na DEA quando na Avaliação Cruzada.

Published: November 2018

O objetivo deste trabalho é avaliar a influência da caminhabilidade no preço de venda de imóveis residenciais, através de um estudo de caso na cidade do Rio de Janeiro. As análises foram conduzidas através de uma abordagem hedônica, utilizando modelos de equações estruturais para construções das variáveis latentes de características não observáveis. Nesse caso enquadra-se a caminhabilidade e a segurança pública, inclusas no modelo testado. Essa metodologia possibilitou a análise da estrutura das variáveis latentes, suas relações mútuas e com o preço dos imóveis. Os resultados obtidos mostram que o preço do metro quadrado de imóveis residenciais à venda na área de estudo cresce conforme aumenta a caminhabilidade. A segurança pública, a declividade viária e a presença de construções aprazíveis foram identificadas como os fatores mais importantes na explicação da caminhabilidade e, consequentemente, na valorização do imóvel.

Authors: Chaves Jéssica Aquino , Carlson Rodrigo Castelan , Müller Eduardo Rauh , Kraus Jr. Werner
Published: November 2018

O Controle do Fluxo Principal (CFP) em autoestradas é um método de controle de tráfego que regula o fluxo de veículos a montante de um gargalo a fim de maximizar o escoamento do fluxo de tráfego na autoestrada. Usando Limites de Velocidade Variáveis (LVV) como atuador do CFP, é analisada a influência de diferentes taxas de penetração de veículos cooperativos no tráfego. Veículos cooperativos foram equipados com Controle Adaptativo de Cruzeiro e recebem como valor de referência o LVV da seção autoestrada em que se encontram. Simulações com o simulador microscópico de tráfego AIMSUN mostraram que o aumento da taxa de penetração contribuiu para o aumento do desempenho. Em cenários cuja taxa de penetração é de 10%, houve uma melhoria de desempenho de 25%. A presença de mais de 50% de veículos cooperativos tem um efeito positivo nas condições de tráfego. Porém, é necessária uma estratégia auxiliar para facilitar a inserção dos veículos ao fluxo principal em gargalos da autoestrada ativados por rampas de acesso.

Published: November 2018

In order to investigate the construction of column-to-beam joints and to understand theeffect of recycled aggregate concrete (RAC) and cross-section of beams and columns on theseismic performance of recycled aggregate concrete-filled light steel tubular frame structure, fournew types of assembly joints were proposed in this paper. A low cyclic loading test of six framespecimens was carried out. The failure characteristic, load bearing capacity, hysteresis property,ductility, strength and stiffness degradation, and energy dissipation were analysed. The damageprocess of the specimen was simulated using the ABAQUS software, and the results agreed wellwith those obtained from the experiments. The results showed that the construction pathway of thejoints exhibited significant influence on the seismic performance of the frame. The proposedreinforced joint (using angle steel and stiffeners) significantly improved the bearing capacity,stiffness and energy dissipation capacity of the recycled aggregate concrete-filled steel tube frame.The seismic performance of the steel frame was improved, while the energy dissipation capacityincreased by 635.7% using RAC filled in the steel tubes. Finally, by appropriately increasing thesize of cross-section on the beams and columns can improve the bearing capacity, stiffness andductility of the structure.

Authors: NagaPavani G. , Lakshmi Prasanna Ch. , N.N. Sastry Dr.
Published: November 2018

For phased array applications covering ultra wide bandwidth, it is necessary to restrict the size of the aperture to less than λ/2 at highest frequency of operation. For 6-18 GHz coverage, an aperture size of less than 9.76mm is required for scanning to ±450 without appearance of grating lobes and occurrence of element pattern nulls over the band. Meeting this requirement a printed tapered slot antenna has been designed with the above aperture size. Detailed parametric studies have been carried out over 6-18 GHz and dimensions have been opti-mized for return loss. The design has been carried out with HFSS software. A return loss of less than -7.5dB across 5.6 - 20 GHz has been obtained for a single antenna. Also satisfactory radiation patterns have been obtained.

With the rapid development, Microblog as an important interactive media, has become a kind of transmission carrier of the false information. Therefore, the research significance of Micro-blog information credibility becomes more and more important today. In this paper, different representative factors are selected from three facets--text contents, information dissemination and information source--which influence the information credibility of Micro-blog. We choose Netica software to build Bayesian network model and use the rumors grabbed from Sina Weibo as experimental data in order to get the relationship between conditions and phenomena from the changes of probability distribution in Bayesian network. On the basis of this, we find the influences of the representative factors on the subjective credibility of objective unreliable information.

Authors: Diachenko Leonid , Benin Andrey , Diachenko Anastasia
Published: November 2018

Track-bridge interaction problems have a main role in the design of bridges on high speed railways (HSR). In this paper, a technique is described for performing calculations of the interaction of the elements of the "bridge-jointless track" system. The complexity of these calculations lies in the nonlinear relationship between the bridge spans and the railway track. The characteristics of these relationships are largely determined by climatic factors (summer and winter conditions), as well as the presence of temporary loading on the bridge. The results of the interaction "bridge-jointless track" system are presented at temperature and train impacts for the characteristic types of bridge structures in the form of multi-span beams and continuous beams. The influence of the length, the construction scheme, the longitudinal stiffness of the intermediate supports on the magnitude of the forces arising in the rails of the continuous path is shown. Based on the performed calculations, conclusions were drawn about the characteristic modes of operation of the "bridge-jointless track" system and recommendations were made on constructive measures reducing efforts in rails.

An ontology-based semantic similarity metric to empower semantic search
Authors: Parveen Suraiya , Biswas Ranjit
Published: November 2018

Heterogeneity in documents is a challenge for information Retrieval. The keyword search focuses on matching the keywords with web repositories. It does not consider the synonyms or semantically similar words. The heterogeneity of the content makes retrieval inadequate. Semantic search helps to capture more appropriate results using domain ontology. Keyword search is extended with the help of similar concepts of ontology. Similarity between the ontological concepts is recognized to get appropriate search results. Once the semantic similarity among the concepts is known, more relevant documents can be retrieved. In this paper, we propose a metric based on traditional methods, combined with computational techniques to measure the similarity between concepts. The paper gives the concept of DOT (Domain Ontology Tree). It uses conventional definitions of the Tree (Data Structure) for ontology and proposes a method of partitioning to calculate the similarity. The method is based on IS-A hierarchical relationship. We have implemented a prototype system for the support of the proposed method, and also compared it with existing methods, the results are encouraging.

Toll plazas are one of the critical components of a roadway system. At the same time, they are among the most complex road structures, as drivers are exposed to a large amount of information and have a short amount of time to make a decision to avoid any collision. VISSIM and SSAM are used to investigate the effect of various Malaysian toll plazas design and traffic conditions on drivers’ behaviour and level of safety. The study was made a well-calibrated and validated VISSIM simulation model and several scenarios were simulated to test their efficacy for improving toll plaza safety aspects by using SSAM afterwards. From the results it was observed that the VISSIM simulation model scenarios such as implementing booths orientation and segregating lanes for different vehicle types to improve the level of service have significant safety aspects improvement regarding conflict points and lane change accidents results while using Surrogate Safety As-sessment Model (SSAM) in order to give the need for remediation of either the roadway design or the flow-control strategy.

Improving the yield as well as the perform of subspace clustering is one of the less-investigated topics in high-dimensional data. After reviewing existing approaches, it seriously felt that there is a need for classification of data points retrieved from a different number of subspace. The proposed study has presented a novel framework that targets to improve the accuracy of subspace clustering by addressing the problem associated with the exist of occlusion noise and dimensional complexity. An analytical approach as been proposed to design this framework with more emphasis on outlier minimization followed by obtaining optimal clusters. The technique also introduces a simple search optimization method, which is less iterative and is more productive for identifying the élite outcomes in each iterative step. The study outcome shows superior accuracy with a low rate of error when compared with the conventional approach.

Published: November 2018

The 2-ethyl-hexanol compound is much needed in the plasticizer industry as a precursor for the synthesis of bis diesters (2-ethyl hexyl) phthalate (DEHP). This compound can be synthesized by oxo reaction. One of the steps in the oxo reaction is consecutive hydrogenation reaction of the 2-ethyl-2-hexenal to 2-ethyl-hexanol. This reaction requires nickel-based catalyst as an effective step for obtaining higher and purer 2-ethyl-hexanol yields. This research aims to develop the formula and procedure of catalyst synthesized in Laboratory of Catalysis and Reaction Engineering Institut Teknologi Bandung and get a rate of the reaction. The catalysts were synthesized by co-impregnation with a nickel content of 20%-w and varied with molybdenum loading (5-20%). The support that used for these metals is alumina-phosphate (AlP2). The synthesized catalysts were tested for their activity against the 2-ethyl-2-hexenal conversion at 120°C, 30 bar in the fixed bed reactor and compared its performance with a commercial catalyst. The results showed the addition of molybdenum loading increases selectivity of 2-ethyl-hexanol but decrease the conversion of 2-ethyl-2-hexenal. The highest selectivity was achieved by Ni5-Mo20/AlP2 (X=31%, S=85%), but the highest conversion was achieved by Ni20/AlP2 (X=88%, S=32%). Nickel tend to play a part of breaking the C=C bond. Meanwhile, molybdenum tends to break the C=O bond. This shows that the hydrogenation of C = C bonds and the C = O bond is very depending on nickel and molybdenum metal loading.

Authors: Abdulrazzaq Kareem Fadhil , Al-Dulaimi Mustafa , Samir Lafta Noor
Published: November 2018

The performance of a forced draft wet cooling tower was investigated experimentally and the calculation was performed by applying second law of thermodynamics (exergy analysis). The mathematical model was developed by using engineering equation solver (EES) software. The results show that the chemical exergy of air increases from the bottom to the top of the cooling tower, the thermal exergy of air decreases from bottom to the top of the cooling, the exergy of water decreases from top to the bottom of the cooling tower. The exergy destruction decreases from bottom to the top of the cooling tower, and the exergy efficiency decreases from top to the bottom of the cooling. The exergy destruction tends to increase as the inlet wet bulb temperature increases while the exergy efficiency decreases. As water-air flow rate ratio increases the exergy destruction increases while the exergy efficiency decreases. The results show that there is an inverse proportional be-tween exergy destruction and exergy efficiency.

Authors: S Gomathi , V Narayani
Published: November 2018

The key objective of the paper focuses on developing the Systemic Lupus Erythematosus prediction tool for the prediction of disease in the early stage using Optimal Cluster based Classification Algorithm (OCBC). Systemic Lupus Erythematosus is an autoimmune, chronic, multi-organ disorder which affects more or less all parts of the body with changing symptoms. There is no cure for the disease; the lifetime of the patients can be extended if diagnosed in the early stage. The death occurs due to various reasons like unawareness, late diagnosis, meeting the right specialist in the severe stage etc. The SLE dataset is tested and applied to various classification algorithms such as ID3, C4.5, J48 and OCBC using SLE prediction tool. As a result, statistics are generated based on all classification algorithms and comparison of all four classifiers is also done in order to predict the accuracy, specificity, sensitivity, precision, recall, F-measure, kappa statistics and to find the best performing classification algorithm among all. In this paper, the screenshots of the tool are also shown. This paper outlines the importance of classification and prediction based data mining algorithms in the healthcare field.

In this paper, I review current status and development strategies in Korean innovation cluster. In particular, I compared the innovation clusters of Daejeon and Gyeonggi - do, and examined the differences and ways of cooperation. Among Daejeon and Gyeonggi-province innovation clusters, the DaedeokInnopolis is focused on R & D and pursues technology commercialization in connection with venture companies. Pangyo Techno Valley is a state-of-the-art IT technology centered on high technology companies. If wide-scale cooperation measures are established between Daejeon and Gyeonggi-do clusters, which are different from each other in the process of formation and complexity, a great synergy will be created at the national level. The future development strategy will be derived by examining the representative innovation cluster in Korea. The first strategic direction is to set up a vision of 'loosely coupled' between the Daejeon and Gyeonggi-do innovation clusters. The second strategic direction is to promote 'loosely coupled' wide-area cooperation programs between clusters. The third strategic direction is to foster an open innovation venture ecosystem.

One of the significant criteria of wireless sensor network is energy efficiency. Focused on the energy problem, researchers design a few algorithms based on clustering in the present era but lack of proper mathematically rigor justification. To fill this research gap, a system and method has been proposed with a mathematical proof induced from the concept of Hessian matrix of multi variable calculus for Energy efficient techniques of data gathering or routing in Wireless Sensor Networks. It is assumed that Wireless Sensor Nodes are distributed in a multidimensional space.  Illustrations verify that the proposed system mathematical design for any clustering approach promises a low-energy communication structure.

Because of increasing demand there is a need for energy storage.Supercapacitor the new age energy storage device which can provide quick burst of energy. The study focuses on use of Polyvinylidene fluoride as the binder material in making of electrodes for supercapacitors. Polyvinylidene fluoride (PVDF) is a highly non-reactive thermoplastic fluoropolymer produced by the polymerization of vinylidene difluoride. It is a strong piezoelectric element. Piezoelectric effect is useful for generation of high voltages. Binder materials are responsible for holding the active material particles within the electrode. The study was focused on use of PVDF in Electric Double Layer Capacitors (EDLC) and Pseudo capacitors. In case of Electric Double Layer Capacitors the PVDF is used as binder material with activated carbon as electrode material. In case of Pseudo capacitor the PVDF is used as a binder material with activated carbon and metal oxide as electrode material. Research was performed with preparation of electrodes using 6 types of Activated carbons namely Vulcun XC 72, Pica, RP20, C60, NORIT and Graphene for different compositions. The test was conducted on single electrode and it was initially charged at a voltage of 2.2V and its discharge was recorded for a time period of 3 minutes. The research focuses on the material which is giving the best results in regarding to the key parameters of supercapacitors and also concentrates on the composition of Polyvinylidene fluoride (PVDF) which gives the highest value of capacitance with the lowest value of Equivalent series resistance in making electrodes for supercapacitors.

Published: November 2018

As Cloud Computing has become a new way to store information remotely. It makes possible for many companies to become paperless. IT people and companies can outsource their huge data by using this emerging technology. The major important characteristics of cloud computing are on-demand self-service, broad network access, resource pooling, rapid elasticity and measured services. These cloud computing characteristics are helpful for organizations to become agile. Also there are few serious problems like security, scalability, availability and interoperability which are associated with the above cloud computing characteristics. Providing a secure and efficient access and retrieval of the valuable data is a main concern of cloud computing technologies. It is very important to protect data and credentials of cloud client on the internet. Apart from these security issues of data, the deletion of data on cloud storage is also a very serious issue nowadays.  Once a cloud user wants to delete his data, it must be sure that data actually deleted from all cloud storage sources and there should not be remain any copy of data exist at anywhere in cloud storage anyway. In this paper, different existing data deletion and retrieval methods are studied, observed and analyzed. The importance and related challenges to assured data deletion on the cloud storage are explored.

The everyday workplace of railroads is backbreaking and frequently includes high-hazard activities. These operations has its impact on railways crew and public people who lives along the town and cities. To avoid the employees and public's exposure to risk, railway companies uses safety training programs[1] , advanced technology concepts like data analytics and machine learning to analyze about frequent accident occurring zones and safety precautions to be taken in advance. So in this paper we are proposing an visualization model for identifying the frequent occurrence of railway accident zones so as to take enough precautions to avoid them. Here we will be collecting the data on the frequently occurring railway accidents and the causes for it. After the data is been collected, we will be analyzing the data and presenting the information about most frequent and less frequent accident prone areas using visualization tools which provides the clear picture of incidents so as certain precautions or counter measures will be taken at proper times to minimize railway accidents. The results of the analysis done can be used to make and communicate decisions about accidents so as to minimize them.

Este trabajo analiza como el mes de nacimiento afecta a los resultados escolares en Lengua y Matemáticas del alumnado de la Comunidad Autónoma de Cantabria en los cursos de 2º, 4º y 6º de Educación Primaria en el periodo 2009-2014. Los resultados muestran que los estudiantes nacidos en los últimos meses del año obtuvieron notas más bajas que sus compañeros de clase. En conjunto, los resultados muestran que los nacidos a final de año tienen una mayor probabilidad de obtener calificaciones más bajas y una probabilidad aumentada de obtener peores notas, tras controlar el efecto del género, ser repetidor y la nota media de los centros docentes. La discusión valora la importancia de modificar los agrupamientos por edad en la enseñanza obligatoria así como la aplicación de políticas de flexibilización (criterial y temporal) de los procedimientos de evaluación del rendimiento de los estudiantes, con el objetivo de garantizar que las notas de los más jóvenes no se vean afectadas por las diferencias en edad relativa.
What’s the purpose? Educators’ perceptions and use of a state-mandated kindergarten entry assessment
Authors: Harvey Hattie , Ohle Kathryn
Published: November 2018

Educator’s perceptions and use of a state-mandated kindergarten entry assessment (KEA), the Alaska Developmental Profile (ADP), were investigated using a mixed-methods approach with 233 educators representing 23 districts in the state of Alaska. Educators reported inconsistencies in the administration, implementation, perceptions, and use of the ADP. These inconsistencies were connected to an unclear understanding of the purpose for the ADP, a finding that most likely reflects the compliance model of those administering state-mandated assessments instead of educators seeing these tools as useful for instructional decision-making. Results suggest policy makers should strive to ensure all stakeholders have a clear understanding of the purpose for a state-mandated KEA and that systems are in place to ensure reliability and validity of the data. Teachers are urged to become familiar in using formative, observation-based assessment approaches and consider how data gathered from a KEA can provide meaningful information for instructional planning. Administrators are encouraged to provide the professional development and support needed to engage in data-driven decision making. And finally, researchers are reminded of their role in helping conduct research that examines the processes and impact of state-mandated assessments.
ASPEK KEADILAN DALAM KONTRAK BISNIS DI INDONESIA (Kajian pada Perjanjian Waralaba )
Authors: Priyono Ery Agus
Published: November 2018

Perjanjian, esensinya adalah kesepakatan, disifati dengan bertemunya kehendak (meeting of mind, mutual assent ) para pihak untuk mencapai suatu tujuan yang telah disepakati guna memberikan kemanfaatan semaksimal mungkin bagi para pihak. Perjanjian layaknya sebuah dokumen hukum sudah sepantasnya memenuhi minimal tiga unsur sebagaimana dikatakan oleh Gustav Radbruch, yakni keadilan, kemanfaatan dan kepastian hukum, akan tetapi faktanya aspek kepastian hukum (dhi asas Pacta Sunservanda) paling menonjol bahkan kadang mengabaikan keadilan.Tulisan ini bertujuan untuk mengungkap mengapa hal tersebut terjadi, apa sebabnya dan bagaiamana solusinya.Pendekatan penelitian normatif filosofis digunakan untuk menganalisis dokumen kontrak mengacu pada peraturan yang terkait dan asas asas perjanjian. Sebagai kesimpulan tidak tercapainya keadilan bagi para pihak khususnya penerima waralaba, dikarenakan posisi tawar pemberi waralaba (franchisor) yang sangat kuat,  tidak seimbang jika dibandingkan dengan posisi tawar penerima waralaba (franchisee) yang lemah. Hal ini berimbas pada isi kontrak yang sepenuhnya dibuat oleh pemberi waralaba (franchisor), yang tentunya cenderung memberikan manfaat sebesarbesarnya bagi pemberi waralaba (franchisor).
