B\"acklund Transformations for First and Second Painlev\'e Hierarchies

We give B\"acklund transformations for first and second Painlev\'e hierarchies. These B\"acklund transformations are generalization of known B\"acklund transformations of the first and second Painlev\'e equations and they relate the considered hierarchies to new hierarchies of Painlev\'e-type equations

Kesan aplikasi pembelajaran berteraskan multimedia terhadap pelajar teknikal dari aspek gaya pembelajaran visual di politeknik Malaysia

Visual dalam pendidikan adalah pendekatan yang mampu melatih keupayaan pelajar untuk memahami sesuatu konsep pembelajaran yang baru dengan mudah mahupun meningkatkan tahap pemahaman. Kajian ini adalah bertujuan untuk mengenalpasti perkaitan diantara penggunaan aplikasi pembelajaran dengan gaya pembelajaran visual pelajar dalam matapelajaran Computer Networking Fundamentals. Responden kajian ini adalah terdiri daripada pelajar semester 5 daripada 2 buah Politeknik iaitu Politeknik Ibrahim Sultan, Johor, dan Politeknik Port Dickson, Negeri Sembilan yang mengambil matapelajaran Computer Networking Fundamentals (EC301) . Seramai 19 responden yang diambil sebagai kumpulan rawatan daripada Politeknik Ibrahim Sultan (PIS) dan seramai 21 responden lagi berfungsi sebagai kumpulan kawalan daripada Politeknik Port Dickson (PPD). Terdapat 3 instrumen yang digunakan untuk menjalankan kajian ini. Instrumen pertama adalah aplikasi pembelajaran bagi matapelajaran Computer Networking Fundamentals (EC301) yang digunakan oleh kumpulan rawatan, borang kaji selidik untuk mengenalpasti gaya pembelajaran setiap responden, dan intrumen yang ketiga adalah set ujian penilaian (ujian pra dan ujian pasca) bagi menilai tahap pencapaian kesemua responden. Data dianalisis menggunakan Analisis ANCOVA dan hasil kajian mendapati bahawa, pelajar yang menggunakan aplikasi pembelajaran dan disesuaikan dengan gaya pembelajaran visual (A_V) mencapai skor min markah yang paling tinggi iaitu 10.194 berbanding dengan kategori pelajar yang bukan bergaya pembelajaran visual dan tidak menggunakan aplikasi pembelajaran yang masing-masing hanya mencapai skor min 9.417 (A_BV), 4.950 (BA_BV) dan 3.646 (BA_V). Berasaskan kepada hasil dapatan ini, satu kerangka perlaksanaan telah di syorkan dengan menggabungkan intervensi aplikasi pembelajaran dengan elemen gaya pembelajaran visual bagi meningkatkan daya kefahaman pelajar semasa proses pengajaran dan pembelajaran

ANALISIS MODEL PENANGANAN GARIS PANTAI DI PANTAI UJUNG PANDARAN KABUPATEN KOTAWARINGIN TIMUR

Wilayah Pantai Ujung Pandaran Kecamatan Teluk Sampit Kabupaten Kotawaringin Barat telah mengalami abrasi pantai sebesar 3,262 Ha selama tahun 2014 – 2017. Hal tersebut dapat diantisipasi dengan penanganan baik secara struktur lunak maupun keras. Penelitian ini dilakukan untuk mengetahui model penanganan abrasi Pantai Ujung Pandaran. Berdasarkan hasil analisis menunjukan bahwa penanganan pantai yang terabrasi dapat dilakukan dengan struktur keras melalui sabuk pantai dan revetment. Sabuk pantai dibangun berada pada kedalaman 0,9 – 1,5 meter MSL dengan lebar celah sejauh 10 – 20 meter, sedangkan revetment di bangun pada celah antara sabuk pantai. Bentuk bangunan tersebut dapat mengurangi abrasi pantai dan akan terbentuk cuspate di belakang bangunan pantai

ANALISIS KERENTANAN PANTAI BERDASARKAN COASTAL VULNERABILITY INDEX (CVI) DI PANTAI KOTA MAKASSAR

The vulnerability of Makassar coast was measured using parameters of Coastal Vulnerability Index (CVI). CVIvalue was determined using geomorphology, shoreline change, coastal slope, mean wave height, mean tidalrange, and relative sea level change parameters. The Makassar coast was divided into a numbers of cells, eachwith the length of 1 km and width of 0.5 kminto the sea. CVI values werecalculated for each cell and the coastalvulnerability wereclassifiedinto five categories: very low - low - medium - high - very high. The results show thatthe coastline with high to very high vulnerability index are located at the southern part of Makassar, while thenorthern coastline generally have low to moderate vulnerability. The CVI parameters which contributed to highsusceptibilitywere the coastal slope and the shoreline change parameters. Keywords: Coastal Vulnerability Index, coastal slope and shoreline change, Makassar

Predictive model of the human muscle fatigue: application to repetitive push-pull tasks with light external load

Repetitive tasks in industrial works may contribute to health problems among operators, such as musculo-skeletal disorders, in part due to insufficient control of muscle fatigue. In this paper, a predictive model of fatigue is proposed for repetitive push/pull operations. Assumptions generally accepted in the literature are first explicitly set in this framework. Then, an earlier static fatigue model is recalled and extended to quasi-static situations. Specifically, the maximal torque that can be generated at a joint is not considered as constant, but instead varies over time accordingly to the operator's changing posture. The fatigue model is implemented with this new consideration and evaluated in a simulation of push/pull operation. Reference to this paper should be made as follows: Sakka, S., Chablat, D., Ma, R. and Bennis, F. (2015) 'Predictive model of the human muscle fatigue: application to repetitive push-pull tasks with light external load', Int

Design method for an anthropomorphic hand able to gesture and grasp

This paper presents a numerical method to conceive and design the kinematic model of an anthropomorphic robotic hand used for gesturing and grasping. In literature, there are few numerical methods for the finger placement of human-inspired robotic hands. In particular, there are no numerical methods, for the thumb placement, that aim to improve the hand dexterity and grasping capabilities by keeping the hand design close to the human one. While existing models are usually the result of successive parameter adjustments, the proposed method determines the fingers placements by mean of empirical tests. Moreover, a surgery test and the workspace analysis of the whole hand are used to find the best thumb position and orientation according to the hand kinematics and structure. The result is validated through simulation where it is checked that the hand looks well balanced and that it meets our constraints and needs. The presented method provides a numerical tool which allows the easy computation of finger and thumb geometries and base placements for a human-like dexterous robotic hand.Comment: IEEE International Conference on Robotics and Automation, May 2015, Seattle, United States.

Developing a national database on Librarianship and Information Science. The case of E-VIVA, the Hellenic fulltext database

The paper presents the Hellenic fulltext database on Librarianship and Information Science E-VIVA (Ellinike Vivliothikonomike Vase), developed by the Library of the University of Cyprus. The objectives of E-VIVA is to identify, gather, organize, digitize and promote the research, conducted in Greece and Cyprus in the scientific fields of Archival, Library and Infor-mation Sciences. Data are provided concerning the cov-erage, the content, the format and the environment of the database as well as the steps that have been fol-lowed for the development. The legal framework related with the copyright issues that are raised is also dis-cussed. Furthermore a comparison is attempted be-tween E-VIVA, eLIS, LISA and LISTA. Finally the next plans of the Library of the University of Cyprus for the project are presented

Transformation properties of Painleve VI equation

Ankara : Department of Mathematics and Institute of Engineering and Sciences, Bilkent University, 1995.Thesis (Master's) -- Bilkent University, 1995.Includes bibliographical references leaves 26.In this thesis, we studied the Schlesinger transformations of Painleve VI equation. We showed that Painleve VI equation admits Schlesinger transformations which relate a given solution of Paileve VI to solution of Painleve VI but with different values of the parameters. Using these transformations we obtained the corresponding Bäcklund transformations for Painleve VI. Also, we showed that the Schlesinger transformations and the corresponding Bäcklund transformations break down if and only if Painleve VI has certain one-parameter family of solutions.Sakka, AymanM.S
