Correlation between Reading Comprehension Skills and Students’ Performance in Mathematics

https://ijere.iaescore.com/index.php/IJERE/article/view/4432
Ombra A Imam , Maripaz Abas Mastura , Hazri Jamil
The deteriorating performance of Filipino students in the national and international mathematics tests for the last decade has become a major challenge to Philippine education.  The Department of Education attributed this problem to students’ poor reading comprehension. Previous studies showed varied findings on the association between variables in reading and mathematics. The present study utilized the six elements of reading comprehension skills to determine their relationship to students’ performance in mathematics. A total of 666 students belonging to the randomly selected first year classes from 18 public and private high schools were taken as sample. A correlation research design was used and a competency-based achievement tests in reading comprehension and mathematics were the research instruments. Students in private schools performed better in reading comprehension skills and mathematics than their counterparts. While reading comprehension skills were insignificantly correlated to private school students’ mathematics performance, the case is different in public schools wherein three skills namely understanding vocabulary in context, getting main idea, and making inference surfaced to have connection with mathematics. The overall students’ reading comprehension skills were not significantly correlated to mathematics performance. Hence, the poor mathematics performance could be explained by other factors not related to reading comprehension skills.DOI: http://dx.doi.org/10.11591/ijere.v2i1.1803

Similar Constructive Method for Solving a nonlinearly Spherical Percolation Model

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/2107
WANG Yong , BAO Xi-tao , LI Shun-chu
In the view of nonlinear spherical percolation problem of dual porosity reservoir, a mathematical model considering three types of outer boundary conditions: closed, constant pressure, infinity was established in this paper. The mathematical model was linearized by substitution of variable and became a boundary value problem of ordinary differential equation in Laplace space by Laplace transformation. It was verified that such boundary value problem with one type of outer boundary had a similar structure of solution. And a new method: Similar Constructive Method was obtained for solving such boundary value problem. By this method, solutions with similar structure in other two outer boundary conditions were obtained. The Similar Constructive Method raises efficiency of solving such percolation model. DOI: http://dx.doi.org/10.11591/telkomnika.v11i3.2219

University Belongingness Scale: Measurement and Construct Verification in Indonesian Language

https://ijere.iaescore.com/index.php/IJERE/article/view/4433
Triantoro Safaria
Sense of  belonging is the extent to which  person feels attached, related and belong in organization system. If, a person feels accepted,   comfortable, congruence and get recognition from an organization, this condition will motivate the person to share positive contribution to their organization. The problem with Ahmad Dahlan University is a low student sense of belonging to their university.  This condition will cause negative effects for university in the future, with increasing several students’ negative behaviors such as apathy, unresponsiveness, until higher students drop out.  It is needed to evaluate and understand the student’s sense of belongings to their university, in order to take preventive action related to a low sense of belongings of students. The aim of this study is to create and develop a sense of belongingness measurement for Ahmad Dahlan University Belongingness Scale (ADUBS), that it will be used to evaluate how high the student sense of belonging to their university. The result of exploratory factor analysis (EFA) showed two dimensions the sense of belongingness constructs that represent the sense of belongings of student to their university namely University belongings and Community belongings. The next result from confirmatory factor analysis (CFA) using structural equation modeling (SEM) confirms that measurement model of ADUBs was fitted with empirical data (Chi-square = 39.054, with p > .001, degree of freedom = 36,  CMIN = 1.085,  RMSEA =. 022, NFI = .918, TLI = .989, GFI= .961, and CFI= .993.DOI: http://dx.doi.org/10.11591/ijere.v2i1.1667

Low Voltage Ride-Through of Doubly Fed Induction Machine using Direct Torque Control Strategy

https://ijpeds.iaescore.com/index.php/IJPEDS/article/view/4935
G. Venu Madhav , Y. P. Obulesu
The wind turbines based Doubly Fed Induction Machine (DFIM) not able to support the voltage and the frequency of the grid during and immediately following the grid failure. This would cause major problems for the systems stability, but the turbines should stay connected to the grid in case of a failure. This can be achieved by using crowbar protection in particularly during voltage dips. When low depth voltage dips occur, the necessity of crowbar proctection can be eliminated by using proposed Direct Torque Control (DTC), with a proper rotor flux generation strategy, by which during the fault it will be possible to maintain the machine connected to grid, generating power from the wind, reducing the stator and rotor over currents, eliminating the torque oscillations that normally produce such voltage dips and fast dynamic response accompanies the overall control of the wind turbine.DOI: http://dx.doi.org/10.11591/ijpeds.v3i1.1733

https://ijere.iaescore.com/index.php/IJERE/article/view/4435
George Abraham , Balasubramanian V. , RA. K. Saravanaguru
This paper aims to provide a survey of the major research works done in the domain of learning style recognition in an e-learning environment and proposes a Semantic Agent Framework for the e-Learning environment to detect individual differences existing among individuals, using their learning styles. Automatic detection of learning styles of an individual in an e-learning environment is an important problem that have been researched upon by many, as it proves beneficial to the learners to be provided with materials based on their individual preferences. To achieve this dynamic adaptability, we propose to use a mix of data-driven approach and literature-based approach. Out of the 71 models of learning styles that are described by different researchers, we consider the Felder-Silverman Learning Style Model (FSLSM) for our analysis.DOI: http://dx.doi.org/10.11591/ijere.v2i1.2517

Design and Implementation of Video Shot Detection on Field Programmable Gate Arrays

10.11591/ijra.v2i1.pp17-25
Jharna Majumdar , Darshan K M , Abhijith Vijayendra
Video has become an interactive medium of communication in everyday life. The sheer volume of video makes it extremely difficult to browse through and find the required data. Hence extraction of key frames from the video which represents the abstract of the entire video becomes necessary. The aim of the video shot detection is to find the position of the shot boundaries, so that key frames can be selected from each shot for subsequent processing such as video summarization, indexing etc. For most of the surveillance applications like video summery, face recognition etc., the hardware (real time) implementation of these algorithms becomes necessary. Here in this paper we present the architecture for simultaneous accessing of consecutive frames, which are then used for the implementation of various Video Shot Detection algorithms. We also present the real time implementation of three video shot detection algorithms using the above mentioned architecture on FPGA (Field Programmable Gate Arrays).

CHEN Zhong-xiao , CUI Ke , CHEN Xing-yu , LI Yan-fang
To deal with the complexity and uncertainty of distribution network fault information, a method of fault diagnosis based on granular computing and BP is proposed. This method uses attribute reduction advantages of granular computing theory and self-learning and knowledge acquisition ability of BP neural network. It put granular computing theory as the front-end processor of the BP neural network, namely simplify primitive information making use of granular computing reduction, and according to the concepts of relative granularity and significance of attributes based on binary granular computing are proposed to select input of BP, thereby reducing solving scale, and then construct neural network based on the minimum attribute sets, using BP neural network to model and parameter identify, reduce the BP study training time, improve the accuracy of the fault diagnosis. The distribution network example verifies the rationality and effectiveness of the proposed method.DOI: http://dx.doi.org/10.11591/telkomnika.v11i3.2184

Precise Pose Alignment through the Combined Method of Differential Evolution and Simplex Algorithm

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/2130
Jian Gao , Liangsheng Xu , Yueping Chen , Xin Chen , Detao Zheng
In reverse engineering applications, there is a problem of precise alignment from measured data to a CAD model. This paper presents a new method where the measurement points can be precisely aligned with its corresponding CAD model. Initially, the measured data is aligned approximately through a least-square method with the minimum distance principle. Based on this initial alignment result, the precise alignment is completed through the Differential Evolution (DE) algorithm and the Simplex method. The experimental results show that the alignment algorithm proposed in this paper possesses an accuracy of 0.055m and spending less processing time than the genetic algorithm. Therefore, the proposed method is effective for the measured data alignment to the original surface model. DOI: http://dx.doi.org/10.11591/telkomnika.v11i3.2310

Flexible Morphogenesis based Formation Control for Multi-Robot Systems

10.11591/ijra.v2i1.pp26-34
Jan Carlo Barca , Eugene Eu-Juin Lee , Ahmet Sekercioglu
Inspired by how biological cells communicate with each other at a cell-to-cell level; morphogenesis emerged to be an effective way for local communication between homogenous robots in multi-robot systems. In this paper, we present the first steps towards a scalable morphogenesis style formation control technique, which address the drawbacks associated with current morphogenesis type formation control techniques, including their inability to distribute robots evenly across target shapes. A series of experiments, which demonstrate that the proposed technique enables groups of non-holonomic ground moving robots to generate formations in less than 9 seconds with three robots and less than 22 seconds with five robots, is also presented. These experiments furthermore reveal that the proposed technique enables groups of robots to generate formations without significantly increasing the total travel distance when faced with obstacles. This work is an important contribution to multi-robot control theory as history has shown that the success of groups often depends on efficient and robust formation control.

https://ijeecs.iaescore.com/index.php/IJEECS/article/view/2095
Ye Zhao , Hu Jinlong , Zhang Ling
With the development of the IPv6 networks, more and more applications put forward to use multicast. Multicast security and management is one of the key issues for IP multicast services deployment in IPv6 network as in IPv4 network. We introduce the idea of Service-Oriented Architecture (SOA) in software scope to multicast service, and design a Service-oriented Controllable Multicast Model (SOCMM) for IPv6 multicast services. And the reference implementation of this model is proposed in this paper. DOI: http://dx.doi.org/10.11591/telkomnika.v11i3.2207

A Subjective Academic Narrative: Practice-Led Research and Indigenous postgraduate opportunities

https://ijere.iaescore.com/index.php/IJERE/article/view/4436
Josie Jacqueline Arnold
The methodology of this paper continues the work I have done writing the ‘subjective academic narrative’ for publication within refereed academic journals. Storytelling is a basic human activity and the academy since the mid 20th century has begun to see its value rather than use it as the non-academic side of the dichotomy between thought and reason and feeling and emotion that the Enlightenment left as its residue of academic thought and knowledge. I use this methodology to enter into the privileged academic discussion and to add to it regarding the  relationship of Indigenous knowledge to the academy that remains a challenge in Australian Universities in this postmodern and postcolonial moment. This paper recognises the need to open discussion about how Indigenous people might be facilitated within the academy to bring their knowledge-models into the university and its traditional dominant knowledge systems. This paper looks at Practice Led Research (PLR) as a possible pathway for supporting the transition of Indigenous community scholars into university postgraduate courses. It explores how PLR contributes to an appropriate entry point into postgraduate studies for some Indigenous students who have significant life experiences and narratives and/or productions of artefacts that act to replace the breadth of undergraduate credentials. This paper identifies and explicates a nexus between Practice Led Research and Recognition of Prior Learning (RPL) and Recognition of Current Competencies (RCC). In doing so, it provides a reference point for University protocols and practices regarding RPL and RCC.DOI: http://dx.doi.org/10.11591/ijere.v2i1.1715
