Program pembudayaan literasi dan teknologi maklumat : Persatuan Pustakawan Malaysia 2011/2012

The Librarians Association of Malaysia in cooperation with Perbadanan Perpustakaan Awam Terengganu (PPAT), Perbadanan Perpustakaan Awam Negeri Sembilan (PPANS), Perbadanan Perpustakaan Awam Negeri Melaka (PERPUSTAM) and Kuala Selangor District Education Office with support from the Faculty of Information Management, Universiti Teknologi MARA (UiTM) through funds from the Malaysian Ministry of Information, Communication and Culture, Permodalan Nasional Malaysia and Telekom Malaysia (TM) organised the Culturalisation of Information Literacy and Technology Programme throughout 2011 dan 2012. The programme used a learning module that covers five aspects which focused on developing information literacy among students to equip them with the knowledge for recognising the need, searching, evaluating and using authoritative and useful information throughout their learning process

Experimental investigations into the behavior of scaling factors in a fuzzy logic speed control induction motor with model reference adaptive control

This paper presents a self-tuning fuzzy logic speed controller (FLSC) with model reference adaptive control (MRAC) for an induction motor (IM) drive system. The MRAC is examined by output scaling the factor tuner for optimum motor speed performance. A detailed investigation is carried out on the scaling factor control of the input change error and main FLSC output increment. This proposed method utilizes seven simplified rules of the 5 × 5 matrix membership functions to minimize the computational burden and memory space limitations. All simulation work is conducted using Simulink and Fuzzy Tools in the MATLAB software and the experimental testing with the aid of a digital signal controller board, dSPACE DS1103. Based on the results, the output scaling factor makes a more significant impact on the performance effect compared to the input error scaling factor. The input change error and output SF also exhibit similar behavior, indicating that a large range of UoD tuners works well in terms of capability load rejection while a small range of UoD tuners performs well in terms of rise time. The analysis includes no-load and load tests to ascertain the overshoot percentage, rise time, and settling time for transient and steady-state conditions

Integrated land use assessment: the case of Klang Valley Region, Malaysia

The dynamic nature of planning and monitoring of development in Klang Valley, the fastest growing region in Peninsular Malaysia, apparently requires a ‘tool’ for continuous evaluation and analysis of current environment as well as the capacity for future development. As such, the concept of Integrated Land use Assessment (ILA) was introduced through the “Application of GIS for Klang Valley Region” (AGISwlk) project. The ILA model developed is implemented through incorporation with the use of What if?, a scenario-based, policy-oriented planning support system. A user interface is also developed to ease the access and preparation of data from the AGISwlk database to run the ILA model and generate alternative scenarios

Physical and mechanical properties of injection molded co-cr-mo alloy powder for orthopedic applications

Cobalt-chromium alloys are commonly used for surgical implants because of their high strength, superior corrosion resistance, non-magnetic behavior, and biocompatibility. Cobalt- Chromium-Molybdenum (Co-Cr-Mo) applications include prosthetic replacements of hips. This paper presents the attempt to produce metallic implant using Co-Cr-Mo powder by MIM process, focusing on the effects of different heating rate during sintering process at 1380 oC. Co-Cr-Mo powder was mixed homogeneously with palm oil based binder with powder loading of 65 vol% and was injection molded using vertical injection molding machine with the nozzle temperature of 160 °C to produce green compacts. The binders were then removed by solvent extraction process and sintered in vacuum condition at 10-5 mbar at 1380 °C. Results indicated that sintered density and tensile strength varies from 8.1 g/cm3 to 8.2 g/cm3 and 546 MPa to 797 MPa respectively. The mechanical properties comply with the international standard (ASTM F75)

Evaluation of Unknown Tube Well Depth Using Electrical Resistivity Method

Electrical resistivity method has increasingly adopted in engineering, environmental, mining and archaeological studies. Systematic and proper studies of unknown civil engineering structure evaluation particularly on tube well depth was rarely being established. Conventionally, camera test or string with weight approach has been used to evaluate unknown tube well depth thus exposed to several restriction due to its expensive and time consuming. Hence, this study focused on evaluation of unknown tube well depth using indirect test with particular reference to electrical resistivity method (ERM).A single spread line of electrical resistivity survey was performed using ABEM SAS 4000 equipment set based on Wenner and Pole-dipole array in line with the tube well position. Electrical resistivity raw data was processed using RES2DINV software producing electrical resistivity tomography (ERT) of the subsurface profile studied. Then, electrical resistivity value (ERV) obtained from RES2DINV analyses (ERT) was extracted and analysed using plotted graph (depth versus ERV) specifically at tube well position based on electrical resistivity spread line performed. It was found that both array have shown some good similarity results in term of tube well depth (20 m) thus able to verify the result interpreted. Both array have shown some good similarity of ERV representing groundwater (ERV = 10 – 100 Ωm) and soil with water (ERV > 100 Ωm) at depth of 0 – 20 m and >20 m respectively. All those interpretation have shown good agreement based on verification thru established ERV of earth materials references, geological map and nearest available boreholes data. Hence, this study has shown that the application of ERM was applicable in evaluation of unknown tube well depth which efficient in term of cost, time and environmental sustainable

The study of degradation and mechanical properties of poly(lactic) acid (PLA) based 3D printed filament

Abstract Additive manufacturing, commonly known as 3D printing technology, has become one of the mainstream processes in the manufacturing industry due to its advantages over conventional manufacturing, which have piqued the public’s interest. This study aims to focus on the influence of thermal conditions on crystallization towards mechanical properties of 3D printed poly(lactic) acid (PLA) degradation samples with 100% infill. As for the degradation profile, the highest weight loss recorded by the samples was 0.7%, observed in samples buried in soil with an abiotic medium for one month. The exposure of degraded samples to high temperature during drying affected their crystallinity, resulting in significant changes in strains, particularly between week 1 and week 2, where strains dropped significantly from 7.33% to 4.28%, respectively. In conclusion, it has been demonstrated that degradation for PLA material still can occur in an abiotic medium, albeit at a slower rate compared to a biotic medium due to the presence of additional microorganisms and bacteria. Besides, the post-heat treatment process on PLA degradation samples affects their crystalline structure, resulting in significant changes in mechanical properties, particularly especially strains. Therefore, it can be concluded that different materials exhibit distinct mechanical properties.</jats:p
