Pembelajaran kognitif, psikomotor dan afektif merupakan pembelajaran yang perlu ditekankan dalam konteks pengajaran dan pembelajaran di institusiinstitusi pengajian tinggi. Ketiga-tiga aspek pembelajaran tersebut amat penting bagi melahirkan graduan yang mempunyai ketrampilan yang tinggi dari segi kreativiti, berinovatif, berkaliber, berkompetensi serta mempunyai motivasi kendiri yang tinggi. Kajian ini adalah satu kajian untuk menilai kualiti pengalaman pembelajaran pelajar-pelajar Saijana Muda Kejuruteraan Elektrik di KUiTTHO. Kajian ini meninjau pengalaman pembelajaran di dalam kelas dan di makmal/bengkel dari aspek pembelajaran kognitif, psikomotor dan afektif. Responden terdiri daripada empat puluh orang pelajar Saijana Muda Kejuruteraan Elektrik semester akhir yang dipilih secara rawak. Instrumen yang digunakan dalam kajian ini ialah jenis soal selidik di mana penilaian dilakukan berdasarkan persepsi responden terhadap pengalaman pembelajaran yang ditempuhi sepanjang pengajiannya serta menjalankan sesi temubual dengan beberapa orang responden. Data-data yang dikumpulkan, dianalisis menggunakan SPSS version 11.0 yang melibatkan skor min dan sisihan piawai. Dapatan kajian menunjukkan kualiti keseluruhan pengalaman pembelajaran pelajar adalah di tahap sederhana (skor min = 3.49). Bagi pengalaman pembelajaran di dalam kelas dan makmal, kualitinya adalah di tahap sederhana (skor min = 3.31 dan 3.67 masing-masing). Sementara kualiti keseluruhan pengalaman pembelajaran dari aspek kognitif, psikomotor dan afektif juga berada di tahap sederhana (skor min = 3.50, 3.39 dan 3.57 masing-masing). Oleh itu, berdasarkan kualiti pengalaman pembelajaran pelajar yang sederhana ini, pengkaji telah membina satu produk cadangan iaitu Sistem Senarai Semak Kualiti Pengajaran dan Pembelajaran bagi membantu pihak pengurusan akademik KUiTTHO meningkatkan kualiti pengajaran dan pembelajaran dari ketiga-tiga aspek kognitif, psikomotor dan afektif

A supplier selection strategy within the Malaysian telecommunications industry

The telecommunication industry in Malaysia has grown rapidly over the last 15 years, with effective supply chain management becoming increasing important within the sector. A multitude of providers and part owned Malaysian government companies, vendors and suppliers are involved in generating and creating value-adding products and services within this sector (across wireless, wireline, broadband business and consumer lines of business). This paper describes key challenges facing a major telecoms service provider in Malaysia with regards to drivers involved in the overall procurement and supplier selection with regards to components of performance management, decision-making, selection techniques, quality and cost management, procurement policy and procurement ethics. This paper further focuses on defining and detailing research currently being undertaken to develop a framework for identifying supplier selection drivers that are inherent within the sector and suggests a research approach to investigate and develop strategies for supplier selection for the telecommunications industry in Malaysia

How to Solve the Fronthaul Traffic Congestion Problem in H-CRAN?

The design of efficient wireless fronthaul connections for future heterogeneous networks incorporating emerging paradigms such as heterogeneous cloud radio access network (H-CRAN) has become a challenging task that requires the most effective utilization of fronthaul network resources. In this paper, we propose and analyze possible solutions to facilitate the fronthaul traffic congestion in the scenario of Coordinated Multi-Point (CoMP) for 5G cellular traffic which is expected to reach ZetaByte by 2017. In particular, we propose to use distributed compression to reduce the fronthaul traffic for H-CRAN. Unlike the conventional approach where each coordinating point quantizes and forwards its own observation to the processing centre, these observations are compressed before forwarding. At the processing centre, the decompression of the observations and the decoding of the user messages are conducted in a joint manner. Our results reveal that, in both dense and ultra-dense urban small cell deployment scenarios, the usage of distributed compression can efficiently reduce the required fronthaul rate by more than 50% via joint operation

Bow-Tie Microstrip Antenna Design

In this paper, the bow-tie microstrip antennas have been designed with two different angles of 40° and 80°. An investigaton on the effect of the angle to the return loss and radiation patterns had been carried out. The impedance matching network with the niicrostrip transmission line feeding was used in this study. Simulation and measurement results for the return loss and radiation patterns were presented

Single channel magnetic induction spectroscopy technique for fetal acidosis detection

Current fetal acidosis diagnosis needs an invasive measurement which required a doctor to puncture fetal scalp to acquire blood pH. This method introduced risk to the fetal which fetal scalp may bruise and infected. This paper discusses a noninvasive method employing a single channel magnetic induction spectroscopy technique as an alternative method to diagnose acidosis in fetal without puncturing the fetal scalp. The studies are based on numerical simulation models to investigate the most feasible sensor coil that is sensitive and effective to be implemented in hardware setup as the shape of coil influences directly the sensing performance of the magnetic induction spectroscopy system. The study has found that the circular coil is more sensitive than linear coil. The system tested with different pH samples to mimic the blood pH value. The result is very promising with good correlation approaching 1 has been achieved. Therefore, magnetic induction spectroscopy technique has good opportunity to be applied as an alternative method to detect acidosis in the fetal with circular coil is performed as the best sensing coils for MIS hardware

Tribological investigations on the application of oil-miscible ionic liquids additives in modified Jatropha-based metalworking fluid

This paper studies the applications of modified Jatropha oil-based (MJO) lubricant as potential vegetable-based metalworking fluids, containing additives of two oil-miscible ionic liquids; [P66614][Phosphinate] (PIL) and [N1888][NTf2] (AIL) at 1%, 5%, and 10% weight concentration. The lubricant samples are validated for corrosion, four ball tribology and tapping torque experiments. Using optical microscope, profilometer, AFM, SEM, EDS and XPS analysis, worn surfaces were investigated. The lubrication performance of MJOþAIL10% and MJOþPIL1% samples provide competitive lubrication performance to that other lubricant samples used herein. They have shown improved corrosion inhibition, superior friction reduction, lower worn surface area, excellent surface finish and increased tapping torque efficiency. These superior tribological results correspond to the metal oxide tribofilm formation and anti-corrosion behavior of MJOþAIL10% sample

Preliminary study of online training implementation from multiple perspectives in Malaysian public sectors

In a constantly changing and evolving global and organizational environment, it is necessary to improve the skills of human resources. The innovation of information technologies nowadays has contributed to the exponential expansion in online training in Malaysia. The number employees attending online training courses have increased tremendously but very low percentage of course completion have been reported, thus raised many questions in the implementation of online training in Malaysian public sectors. This study was conducted to construct a research framework on online training implementation in Malaysian public sectors. The criteria of online training implementation are also being determined through different perception of stakeholders. Based on the literature review, the study posited four constructs adopted from Kirkpatrick’s learning theory through Multiple Perspectives Theory. The preliminary study conducted involves 3 set of interviews with respondents involved in providing online training at Malaysia’s National Institute of Public Administration (INTAN) as providers or consultants of public sectors online training. The preliminary findings showed that the criteria are applicable with the mentioned criteria in the literature review thus suitable to be mapped into the conceptual framework
