Horizon Quantum Mechanics for spheroidal sources

We start investigating the extension of the Horizon Quantum Mechanics to the case of spheroidal sources. We first study the location of trapping surfaces in space-times resulting from an axial deformation of static isotropic systems, and show that the Misner-Sharp mass evaluated on the corresponding undeformed spherically symmetric space provides the correct gravitational radius to locate the horizon. We finally propose a way to determine the deformation parameter in the quantum theory.Comment: 14 pages, 1 figure, final version to appear in EP

Kualiti pengalaman pembelajaran pelajar-pelajar sarjana muda kejuruteraan elektrik di Kolej Universiti Teknologi Tun Hussein Onn (KUiTTHO) dari aspek pembelajaran kognitif, psikomotor dan afektif

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

Delay-Exponent of Bilayer Anytime Code

In this paper, we study the design and the delay-exponent of anytime codes over a three terminal relay network. We propose a bilayer anytime code based on anytime spatially coupled low-density parity-check (LDPC) codes and investigate the anytime characteristics through density evolution analysis. By using mathematical induction technique, we find analytical expressions of the delay-exponent for the proposed code. Through comparison, we show that the analytical delay-exponent has a close match with the delay-exponent obtained from numerical results.Comment: Accepted for presentation in ITW-2014. 5 Pages, 3 Figure

Sensor material characterisation for magnetometer application

Pengukuran dan gangguan medan magnet arus terus dan arus ulang-alik memerlukan penderia medan magnet yang mempunyai kepekaan yang tinggi dan stabil. Untuk menghasilkan penderia tersebut, ciri-ciri bahan magnet yang baik telah dikenalpasti. Beberapa jenis bahan magnet yang berbeza telah digunakan untuk mengkaji ciri-ciri dan kesannya terhadap medan magnet. Teras gelang yang diperbuat daripada bahan-bahan magnet tersebut direkabentuk dengan dimensi yang sama bagi membolehkan perbandingan dibuat dengan mudah. Selain itu, rod tunggal dan berkembar juga telah digunakan sebagai teras penderia fluxgate, untuk melihat prestasi setiap jenis penderia tersebut. Kedua-dua penderia tersebut telah diuji dengan menggunakan dua sumber bahan magnet iaitu bar magnet tetap dan solenoid dengan diameter dawai yang berbeza. Isyarat keluaran bagi setiap penderia fluxgate seterusnya diproses bagi mengenalpasti hubungannya dengan ketumpatan medan magnet

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

Analisis Titik Pulang Pokok USAhatani Bawang Merah (Allium Ascolinicum L) Varietas Lembah Palu Di Kelurahan Taipa Kecamatan Palu Utara Kota Palu

This study aims to determine the total cost, production volume, selling price and the amount of revenue that the respondent farmers in the village of Taipa, so farms are run reach break-even point or in other words the farm does not lose nor gain profits. Determining the location of research done intentionally purposive, with the consideration that the Taipa Village is one of the producers of onion varieties Palu valley with a pretty good productivity in the district north of Palu. The analytical method used is the break-even point. The results showed that, total cost of cultivation of onion varieties Palu valley Rp. 20.947.755,92 per growing season, acceptance of Rp. 38,522, 362,87 per season with earned income of Rp. 17.574.606,95 per growing season, break-even point production of 93,73 kg and the break-even point at Rp. 1,874,600

Problema Perempuan Dalam Memilih Produk Unggulan Bank Syariah Mandiri (Bsm)

Syariah bank has developed from year to year, although it is not booming like conventional banks due to various factors. Some experienced problems in its development are the aspects of law, lack of socialization of Syariah Bank, the operational constraints, and public's understanding toward Syariah Bank is still low. All constraints should be analyzed in accordance with the facts which exist in society to have solution as an input to develop Syariah Bank for the future

Relationship Between Leisure Constraints and Residential School Students’ Participation in Recreational Sport Activities

The purpose of this study is to investigate the relationship that exists among these two variables: leisure constraint, and students’ participation in recreational sport activities in selected fully residential schools in Johor. The sample selected comprised of 217 respondents in three fully residential schools in the state of Johor. A pilot test was conducted to obtain the reliability of the instruments used. The Cronbach Alpha showed the overall reliability of above .65. The data collected were coded and analyzed using descriptive and inferential statistics. Based on the analysis done, the following findings were discovered. First, the result indicated that leisure constraint was not affected by gender differences. Male and female students experienced approximately the same amount of constraint. Second, male and female respondents reported differences in the intensity of leisure dimensions constraint experienced. Interpersonal constraint was found to be significantly different in the intensity as compared to the other two leisure constraint dimensions. Third, there was a significant linear negative relationship between leisure constraint and student’s participation (r= -.258, p= .0001, p< .05). This suggested that an increase in the intensity of constraint experienced would likely be followed by a decrease in students’ participation. Fourth, analysis conducted on the leisure constraint dimensions revealed that of the three dimensions, intrapersonal was noted as the most influential (p= .0001, p< .05). In conclusion, the findings confirmed that leisure constraint and students’ participation were interconnected. Each one of it had an effect on another
