As Dificuldades dos Alunos do Ensino Médio na Aprendizagem da Língua Portuguesa: Um Estudo de Caso na Escola Estadual São João Batista – Araripina – Pernambuco, Brasil
Authors: Alves Dijalva Ferreira Lima , Leite Maria Jucilene Lopes 
Published: July 2018

O ensino da Língua Portuguesa, tornou-se um dos grandes gargalos da educação, não apenas de pesquisas acadêmicas, mas também de debates, cursos, seminários e demais eventos científicos, nos quais se discutem problemas relacionados ao processo de ensino-aprendizagem formal da Língua Portuguesa e alternativa para a resolução do problema. Esta pesquisa que tem como objetivo “conhecer as dificuldades dos alunos do ensino médio em relação à aprendizagem da Língua Portuguesa” sente a necessidade de maior reflexão sobre as bases desse processo e, consequentemente, sobre o redimensionamento das atividades de sala de aula, devido ao fato de grande parte dos alunos da educação básica, em particular do ensino médio da escola Estadual São João Batista, não conseguem produzir textos linguisticamente relevantes e adequados aos diferentes propósitos a que um texto pode servir. Acredita-se que, para o professor de Língua Portuguesa, a principal tarefa a ser realizada é a de tornar os alunos leitores críticos e competentes produtores de textos, bem como, poder contar com o apoio dos demais professores dos outros componentes curriculares para que possam contribuir no ensino Língua Portuguesa, resolvendo se não total, ao menos parcial a problemática em estudo.

Authors: Al--Khayyat Kamal , Fakhri Al-Shaikhli Imad , V Vijaykumar 
Published: July 2018

This paper studies the behavior of compressed/uncompressed data on predetermined binary patterns. These patterns were generated according to specific criteria to ensure that they represent binary files. Each pattern is structurally unique. This study shows that all compressed data behave almost similarly when analyzing predetermined patterns. They all follow a curve similar to that of a skewed normal distribution. The uncompressed data, on the other hand, behave differently. Each file of uncompressed data plots its own curve without a specific shape. The paper confirms the side effect of these patterns, and the fact that they can be used to measure the compressibility appeal of compressed data.

The number of sustainability assessment tools in Indonesia is growing rapidly, concerns are raised on whether the assessment results of different tools present similar and valid conclusion about the sustainability performance in manufacturing industry. In this paper, we analyze dimensions of sustainability assessment tools and compare the structures of sustainability tools in Indonesia. Using a coverage analysis to demonstrate the similarity and differences between two sustainability assessments in Indonesia (PROPER and Industri Hijau) we then compare the results of both and analyze it. This study shows that two sustainability assessment tools in Indonesia which are PROPER and Industri Hijau have high variations in their structures, indicators, criteria, and sub-themes despite their similar dimension and purpose. Consequently, these sustainability assessment tools show differences in assessment results and conclusions on the sustainability performance of firms. Future research may propose a new integrated sustainability assessment tool so there will be only one sustainability assessment tool in Indonesia.

Development of labor productivity have to be a first-rate and chronic challenge of those who are accountable for cost control of constructed facilities. Material handling, which includes procurement, inventory, shop fabrication and field servicing, requires special attention for cost reduction. The use of latest equipment and progressive strategies has made feasible wholesale adjustments in construction technology in current a long time. Groups which do no longer recognize the effect of diverse innovations and feature now not adapted to changing environments have justifiably been compelled out of the mainstream of construction activities. The frequent problems of construction industry, customers have an essential position to play. With the aid of its procurement methods, the purchaser impacts the manner a construction project is done, because the tactics affect the form of the project delivery system. What sort of procurement procedures are perceived rational, for one, depends at the underlying assumptions about the characteristic of procurement. A recognized guideline in Lean construction (LC) is that production must be conceived along with transformations (T), flow (F), and value generation (V). Alternatively, it is visible necessary to recognize and cope with the risk of value loss with an identical diligence as the other issues had been to date. Materials management plays an important role in project planning and control. Materials represent a major expense in construction, so minimizing procurement or purchase costs.

Published: July 2018

Ion Sensitive Field-Effect Transistor (ISFET) is a kind of sensor that able to differentiate the ion by replacing the gate of the FET with electrode and the membrane. Membrane acts as selector for the ions whereas the sensor detects the ions and converts it into electrical signal. However, the sensor has weakness to detect main ion from the interfering ion in the mixed solution when the ions have same characteristic. In this work, potassium ion (K+) and ammonium ion (NH4+) was used as the sample for both ions that have similar size. To overcome the problem, the sensor needs to be trained for pre-calibrate and pre-process by developing a model of Artificial Neural Networks (ANN) in MATLAB software. The ANN makes the model learn the pattern by the sample of inputs and outputs to estimate results or to get more accurate data. Backpropagation is used as the learning method of ANN model. The objective of this work is to develop ANN model for ISFET sensor that able to estimate the main ion in mixed solution by learning the pattern of the input and output of the sensor. The ANN model performance can be optimized by altering certain parameters in the learning algorithm. The results show that the model is able to predict with 97% accuracy and has strong and precise estimation ability with R-factor of 91.55%.

Authors: Arif Mat Norman M , Amiruddin Zainuddin M , Mahmud Jamaluddin 
Published: July 2018

This paper investigates the free vibration characteristics of laminate composite beam for various lamination schemes and under various boundary conditions. A beam model with the aspect ratio (length to thickness) of 25 to 150 made of carbon/ epoxy laminates under free vibration were constructed using a commercially available finite element software (ANSYS). The varied parameters are the lamination schemes (cross ply, angle ply and unidirectional ply) and boundary conditions (Clamp-Free (C-F), Clamp-Clamp (C-C), Clamp-Hanger (C-H), Free-Free (F-F) and Hanger-Hanger (H-H) ). For each case, finite element simulations were performed and the natural frequencies were determined. Mode shapes were also analyzed to observe the beam’s deformation behavior. Results showed that increasing aspect ratio will decrease natural frequencies for the first seven mode shapes. In terms of lamination scheme, the unidirectional ply produced the highest frequency (34.26 Hz), followed by cross ply (34.05 Hz) and angle ply (13.60 Hz) at the aspect ratio of 25. In terms of boundary conditions, the Hanger-Hanger boundary condition produced the highest natural frequency (2272.52 Hz) at the aspect ratio of 25, while Clamped-Free boundary condition produced the lowest frequency (2.28 Hz) at the aspect ratio of 150. In general, it can be concluded that the current study is useful and has contributed significant knowledge to better understand of effect of various fiber orientations and boundary conditions on the natural frequencies of laminated composite beam.
Contrast Ratios, Colour Elements, and Polarities in Visual Acuity Measurements
Authors: Hong Chen Ai , Muhamad Nurulain 
Published: July 2018

This study was aimed to investigate the effects of contrast ratios, colour elements, and polarities on visual acuity measurements. The visual acuities of 18 subjects were measured using 6 different modifications of the Landolt C chart in a 4-metre LogMAR design: (M1) black-on-white [contrast ratio: 0.8]; (M2) white-on-black [contrast ratio: 0.8]; (M3) black-on-white [contrast ratio: 0.5]; (M4) yellow-on-green [contrast ratio: 0.8]; (M5) yellow-on-green [contrast ratio: 0.5]; and (M6) black-on-yellow [contrast ratio: 0.8]. Comparative analysis was performed to examine the effects of the three aforementioned parameters on visual acuity measurements. The visual acuities were found to be significantly different between the contrast ratios of 0.5 and 0.8, regardless of whether colour elements were present (black-on-white) or otherwise (yellow-on-green) [Friedman test: c2 (3) = 24.24, p < 0.05]. Interestingly, the LogMAR score was found to be significantly different between the yellow-on-green and black-on-yellow chart designs when the contrast ratio remained constant at 0.8 [Wilcoxon signed-rank test: z = 2.950, p < 0.05]. However, the effect of contrast polarity (positive/ negative) on visual acuity was not significant when the contrast ratio was fixed at 0.8 [Wilcoxon signed-rank test: z = 0.318, p > 0.05]. A lower contrast ratio and mid-range wavelength colour reduced visual acuity. The effect of contrast polarity without colour elements on visual acuity was negligible.
Electrical insulation components reliability assessment and practical Bayesian estimation under a Log-Logistic model
Authors: Chiodo E , P. Di Noia L , Mottola F 
Published: July 2018

This paper deals with the “physical reliability models” assessment and estimation for electrical insulation components. It is well known that the reliability model identification and estimation of most of the modern power system components, such as insulation components, may be better achieved, instead that using limited lifetime data, by the knowledge of the degradation mechanisms. Such mechanisms, which are responsible for component aging and failure, are indeed well established in the field of electrical insulation: this is also the case of the so called “Stress-Strength” models. In particular, the “Log-logistic” model, deduced by a suitable Weibull stress-strength probabilistic model, has found valid applications to the reliability assessment of the insulation components. In the framework of the estimation of such reliability model, a new Bayesian approach, based upon the “Odds Ratio” of the Log-logistic model is developed in this paper, based upon the properties that such information, being proportional to the reliability function, is available to the engineer on the basis of past data; moreover, being proportional to the Weibull scale parameter, allows to exploit known features of its conjugate prior Inverse Gamma distribution. Numerical examples and the results of extensive Monte Carlo simulations demonstrate the feasibility and efficiency of the proposed procedure.

Published: July 2018

The construction industry has been responsible for degrading the environment due to ecological imbalance caused during the extraction and production of building materials. To make this production of construction materials cleaner, the dependency on conventional materials has to be reduced. With this aim, this article presents an experimental study on partial replacement of cement, sand and aggregate by cowdung ash(CDA), granite powder(GP) and marble stone(MS) respectively. For this, four series of mix proportions were prepared to evaluate the compressive strength and the split tensile strength. Replacement ratios of the first, second, third and fourth mixes are (5%CDA, 10%GP, 15%MS), (5%CDA, 15%GP, 30%MS), (10%CDA, 15%GP, 30%MS), (5%CDA, 7.5%GP, 15%MS) respectively. Results revealed that the partial replacement of binders and fillers is effective to enhance compressive and split tensile strength of concrete. This would enable the construction industry to reduce their dependency on river sand and natural coarse aggregate.

Published: July 2018

Effective functionality checking of any software application is the crucial event that determines the quality of outcome obtained. Generally, checking scenarios that involves multiple test cases in mixture with multiple components is time consuming and also increases the quality assurance cost. Selection of suitable method/approach for optimization and prioritization of test cases as well as appropriate evaluation of the application would result in reduction of fault detection effort without appreciable information loss and further would also significantly decrease the clearing up cost. In the proposed method, test cases are optimized and then prioritized by Particle Swarm Optimization algorithm (PSO) and Improved Cuckoo Search algorithm (ICSA), respectively. Finally, the result will be evaluated for software quality measures.
