Halatuju penyelidikan UiTM Cawangan Pahang / Azhan Bin Hashim @ Ismail
No full textTidak dinafikan penyelidikan telah menjadi satu kriteria penting bagi mengukur kecemerlangan sesebuah universiti selain daripada pengajaran dan pembelajaran. Rating sesebuah universiti yang akan diperkenalkan pada tahun ini akan mengambil kira aktiviti penyelidikan seperti yang ditegaskan oleh Menteri Pendidikan Malaysia. Kerajaan Malaysia telah memperuntukan sebanyak RM1.4 bilion dalam Rancangan Malaysia ke-8 bagi membiayai aktivitivi penyelidikan di Malaysia yang kebanyakannya dimonopoli oleh IPTA. Pada masa ini UPM mendahului universiti-universiti lain dari segi perolehan geran IRPA. UiTM walaupun bam saja dinaik taraf kepada universiti telah mengorak langkah dengan jumlah perolehan geran IRPA sebanyak RM7.2 juta pada tahun 2002 menyaksikan peningkatan hampir 800% jika dibandingkan dengan jumlah yang diperolehi di sepanjang 5 tahun sebelumnya. Menyedari akan peri pentingnya penyelidikan bagi sesebuah universiti, pihak pengurusan atasan UiTM telah menyediakan pelbagai insentif bagi menggalakkan aktiviti penyelidikan seperti diambil kira untuk kenaikan pangkat, pengesahan kedalam jawatan, pengurangan ATA dan lain-lain lagi. Perkara ini dapat dilihat dalam strategi pengukuhan akadernik UiTM yang telah dibentangkan oleh Dato Seri Prof. Dr. Ibrahim Abu Shah, Naib Canselor UiTM. Beliau berpendapat teras penyelidikan perlu dirancang secara komprehensif dan berbentuk inovasi. Selain dari itu, Biro Penyelidikan dan Perundingan UiTM telah dinaik taraf kepada Institut Penyelidikan Pembangunan dan Pengkomersialan atau ringkasnya IRDC bagi memperluaskan lagi peranan untuk mempromosi aktiviti penyelidikan dikalangan warga akadernik UiTM.

Comparative studies of elastic properties of commercial-type woods / Azman Kasim, Amran Shafie and Azhan Hashim @ Ismail
No full textWood-based industries has been extremely expanded in develop country like Malaysia as one of the major contribution to the economic growth of the country. Since wood has become popular in our daily usage, one should conscious about the quality of the wood as natural raw materials. Talking about the quality of woods normally we are talking about the type of woods been used. Conventionally, to identify the quality of wood people look at the prices of the woods, which high in price indicated the woods are in a good quality. Scientifically, by going through certain high technological approach, the quality of woods could be identified. In this project, the ultrasonic technology has been used to identify the quality of commercial-type woods by determine the elastic properties of the woods. Ultrasonic measurement technique is apart of nondestructive testing without damaging the targeted samples. Many papers have been discussed nor published regarding the non-destructive testing of woods and forest product industries previously. The objective of the project is to estimate the elastic properties of the selective commercial woods in collaborations with Woods Technology Department, UiTM Pahang. The selected commercial woods have been used are Kempas (Koompadia malaccensis), Chengal (Neobalanocarpus heimii), Tembusu (Fagraca Fragrans), Simpoh {Dillenia Spp.), Rubberwood (HeveaBrasiliensis) and Yellow Meranti (Shorea Spp.). Thus, the data of elasticity could estimate the quality of woods macroscopically

Optimal population size of particle swarm optimization for photovoltaic systems under partial shading condition
No full textParticle swarm optimization (PSO) is the most widely used soft computing algorithm in photovoltaic systems to address partial shading conditions (PSC). The success of the PSO run heavily depends on the initial population size (NP). A higher NP increases the probability of a global peak (GP) solution, but at the expense of a longer convergence time. To find the optimal value of NP, a trade-off is typically made between a high success rate and a reasonable convergence time. The most used trade-off method is a trial-and-error approach that lacks explicit guidelines and empirical evidence from detailed analysis, which can affect data reproducibility when different systems are used. Hence, this study proposes an empirical trade-off method based on the performance index (PI) indicator, which takes into account the weighted importance of success rate and convergence time. Furthermore, the impact of NP on achieving a successful PSO was empirically investigated, with the PSO tested with 16 different NPs ranging from 3 to 50, and 10,000 independent runs on various PSC problems. Overall, this study found that the best NP to use was 25, which had the best average PI value of 0.9373 for solving all PSC problems under consideration

AC losses in Sn-doped Bi1.6Pb0.4Sr2(Ca1-xSnx)2Cu3Oδ superconductors
No full textMeasurements of complex AC susceptibility χ = χ + χ as a function of temperature have been carried out on Sn-doped Bi1.6Pb0.4Sr2(Ca1-xSnx)2Cu3Oδ superconductor samples prepared via the conventional solid state reaction method. All the samples exhibit perfect diamagnetism below 109 K. The χ (T) curves display two-step features, indicating the presence of mixed phases and therefore weakening of the grains' coupling. The amount of shielded volume in Sn-free samples is greater than that in Sn-doped samples. The intrinsic peak due to the small AC losses within the grain was not observed in the χ (T) curves for all samples. However, the coupling peak, TP, for Sn-free samples at an applied field of 1.0 Oe was observed at 89 K and shifted to a lower temperature ranging from 59 K to 64.2 K in Sn-doped samples. The amounts of hysteresis losses above the TP in all doped samples were smaller than that of the Sn-free sample. Therefore, the effect of Sn doping suppressed the inter-granular critical current, Jcm, and the presence of weak links that coupled the superconducting grains
