Development of IR-Based Short-Range Communication Techniques for Swarm Robot Applications
Advances in Electrical and Computer Engineering , 2010, DOI: 10.4316/aece.2010.04010
Abstract: This paper proposes several designs for a reliable infra-red based communication techniques for swarm robotic applications. The communication system was deployed on an autonomous miniature mobile robot (AMiR), a swarm robotic platform developed earlier. In swarm applications, all participating robots must be able to communicate and share data. Hence a suitable communication medium and a reliable technique are required. This work uses infrared radiation for transmission of swarm robots messages. Infrared transmission methods such as amplitude and frequency modulations will be presented along with experimental results. Finally the effects of the modulation techniques and other parameters on collective behavior of swarm robots will be analyzed.
Intelligent Identification System for Tilt Computation Using Low-cost Inertial Sensors
A. Mudheher Hasan,K. Samsudin,A.R. Ramli
Journal of Artificial Intelligence , 2012,
Abstract: Attitude computed using raw gyro measurements through the INS algorithm suffer from unrestricted error escalation during INS-stand alone phase when utilizing low cost IMU sensors without aiding from other sensors. Hence, an intelligent vehicle dynamic identification system is produced in this study to identify the vehicle status and fuse data from multiple low cost gyroscopes and accelerometers to estimate precise tilt angles and reduce the accumulated error through utilizing the corresponding motion characteristics of the accelerometers and gyroscopes. The results obtained using a real field test data shows clearly a significant reduction in tilt error during stand alone INS.
Wavelet-based Pre-filtering for Low Cost Inertial Sensors
A.M. Hasan,K. Samsudin,A.R. Ramli,R.S. Azmir
Journal of Applied Sciences , 2010,
Abstract: This study proposed to de-noise the IMU signal by effectively band-limiting the signal at the output of each inertial measurement sensor prior to its mechanization and further processing by the Strapdown INS (SDINS) algorithm. Wavelet Multi-Resolution Algorithm (WMRA) is utilized to improve the performance of the inertial sensors by removing their short term noise. The aim of this study is to reveal how WMRA is utilized to improve the performance of the inertial measurement unit systems and investigate how wavelet analysis can be used to analyse and de-noise output of the low-cost inertial sensors. The proposed multi-level decomposition was applied to real accelerometer and gyroscopes data obtained from MEMS IMU (MotionPak II). Different level of decomposition and thresholding filter was evaluated to obtain optimal results. Analysis of the results demonstrate reducing the INS position and velocity error for the specific IMU.
The Evolution of Relationship Marketing (RM) Towards Customer Relationship Management (CRM): A Step towards Company Sustainability
Samsudin Wahab,Juhary Ali
Information Management and Business Review , 2011,
Abstract: This paper provides an overview of relationship marketing (RM) and how it evolves to customer relationship management (CRM). Since marketing continuum is the basic concept for relationship marketing it is apt that marketing continuum is explained first. The reviewed literature than discussed the evolution of marketing from the four P’s principle towards more challenge structure combining environment factors and global market scenario ending with customer relationship management philosophy. This paper developed from the rational theories that are very relevant for the practitioners’ who are alert to the environmental changes. This paper ends with more applicable of customer relationship management concepts that are most recent tools to be considered for company growth and sustainability in the millennium age.

Abstract: Suatu penyelidikan mengenai pencegahan dan pengobatan penyakit defisiensi vit. A. di Cibatok, Bogor, telah dilakukan dengan menggunakan oral massive dose vit. A. (retinol palmitat e) 300,000 I.U. dikombinasikan dengan vit E (a tocopherol acetate) 50 I.U. dl. Dua group anak-anak umur 1-6 tahun dipilih masing-masing sebagai group Experiment dan Control yang hanya diberikan placebo. Sedangkan masing-masing group dibagi lagi menjadi golongan-golongan penderita dan golongan Non vit. A. defisiensi (normal). Ternyata setelah 6 (enam) bulan kemudian 90 percent penderita yang mendapat pengobatan menjadi sembuh dan sebaliknya 88.9 percent dari penderita yang mendapat placebo masih tetap menderita defisiensi vit. A. (table 2) Table 3. Menunjukkan adanya pengaruh penyakit infeksi G.I tract terhadap berhasilnya pengobatan dan juga pada umumnya dapat disimpulkan bahwa gizi penderita tidak mempengaruhi pengobatan. Table 4 Kadar Vit. A. didalam darah penderita setelah pengobatan ternyata jauh lebih tinggi dari semula. Sedangkan dalam group yang mendapat placebo tidak terjadi kenaikan. Dari data penyelidikan tersebut dapat disimpulkan bahwa pemberian oral massive dose kombinasi dari vit. A dan E pada anak-anak sebelum sekolah dapat mencegah, mengobati gejala-gejala defisiensi vit. A. di mata.

Mobile Learning Environment System (MLES): The Case of Android-based Learning Application on Undergraduates’ Learning
Hafizul Fahri Hanafi,Khairulanuar Samsudin
International Journal of Advanced Computer Sciences and Applications , 2012,
Abstract: Of late, mobile technology has introduced new, novel environment that can be capitalized to further enrich the teaching and learning process in classrooms. Taking cognizance of this promising setting, a study was undertaken to investigate the impact of such an environment enabled by android platform on the learning process among undergraduates of Sultan Idris Education University, Malaysia; in particular, this paper discusses critical aspects of the design and implementation of the android learning system. Data were collected through a survey involving 56 respondents, and these data were analyzed by using SPSS 12.0. Findings showed that the respondents were very receptive to the interactivity, accessibility, and convenience of the system, but they were quite frustrated with the occasional interruptions due to internet connectivity problems. Overall, the mobile learning system can be utilized as an inexpensive but potent learning tool that complements undergraduates’ learning process
A New Public-Key Encryption Scheme Based on Non-Expansion Visual Cryptography and Boolean Operation
Abdullah M. Jaafar,Azman Samsudin
International Journal of Computer Science Issues , 2010,
Abstract: Currently, most of the existing public-key encryption schemes are based on complex algorithms with heavy computations. In 1994, Naor and Shamir proposed a simple cryptography method for digital images called visual cryptography. Existing visual cryptography primitives can be considered as a special kind of secret-key cryptography that does not require heavy computations for encrypting and decrypting an image. In this paper, we propose a new public-key encryption scheme for image based on non-expansion visual cryptography and Boolean operation. The proposed scheme uses only Boolean operations and therefore requires comparatively lower computations.
From Access to Gratification: Towards an Inclusive Digital Society
Ali Salman,Samsudin A. Rahim
Asian Social Science , 2012, DOI: 10.5539/ass.v8n5p5
Abstract: The aim of this paper is to trace the use of Internet between natives and migrants and examine how the difference in age affects the gratifications derive from the usage leading to digital inclusion. The issue of broadband access to achieve digital inclusion has gained momentum over the years. In Malaysia, access which is the first level of exposure to Information Communication Technology (ICT) has been largely achieved. Recent research has attempted to expand the conception of the divide to move beyond access to consider issues of proficiency and gratification. This study uses a survey research to obtain data. Some 600 respondents, who are divided into natives and migrants were sampled for the study. The literacy/knowledge and skills for internet applications for both the natives and migrants respondents is above average. Information and socialisation gratifications are the main gratifications derived from using the Internet for both the natives and migrants.

Samsudin A Rahim,Latiffah Pawanteh
Asian Social Science , 2011, DOI: 10.5539/ass.v7n2p3
Abstract: Globalization and building of knowledge societies demand higher access to information. Besides investing in appropriate infrastructure and facilitate media literacy, countries must also ensure better access, availability and quality of information to their population. Malaysia has taken the necessary steps to democratize information by enacting several liberalization policies, commercialization of media stations and deregulation of telecommunication industry. To foster a role for media in the democratization of information, Malaysia ensure easy access to information for civil and political participation, guarantee the no censorship of Internet, and create capacity to create knowledge in local dialects.
