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,

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
