"In any heterogeneous system, porting reconfigurable computing is often a highperformance platform for a broad range of computationally challenging issues.However, efficiently utilizing the maximum potential of these reconfigurablesystems is a difficult job without understanding their performancecharacteristics. This work proposes an analytic performance model using PetriNets (PN) for a Reconfigurable OR1200 (ROR1200) soft-core processor with modelvalidation and verifications. By modeling the ROR1200 system using Petri Nets,both behavioral and structural properties existing in parallel systems wereanalyzed. The Bound Level Analysis with respect to the dependency level of datais also performed on Soft Core Processors (SCP) like the ROR1200, the OR1200and the MicroBlaze."

"Cylindrical uranium dioxide pellets, which are the main components for nuclear fuel elements in light water reactors, should have a high density profile, a uniform shape, and a minimum standard quality for their safe use as a reactor fuel component. The quality of green pellets is conventionally monitored by laboratory measurement of the physical pellet characteristics; however, this conventional classification method shows some drawbacks, such as difficult usage, low accuracy, and high time consumption. In addition, the method does not address the non-linearity and complexity of the relationship between pellet quality variables and pellet quality. This paper presents the development and application of a modified Radial Basis Function neural network (RBF NN) as an automatic classification system for green pellet quality. The weight initialization of the neural networks in this modified RBF NN is calculated through an orthogonal least squared method, and in conjunction with the use of a sigmoid activation function on its output neurons. Experimental data confirm that the developed modified RBF NN shows higher recognition capability when compared with that of the conventional RBF NNs. Further experimental results show that optimizing the quality classification problem space through eigen decomposition method provides a higher recognition rate with up to 98% accuracy."

"The routine dailyactivities that tend to be sedentary and repetitive may cause severe healthproblems. This issue has encouraged researchers to design a system to detectand record people activities in real time and thus encourage them to do morephysical exercise. By utilizing sensors embedded in a smartphone, many researchstudies have been conducted to try to recognize user activity. The most commonsensors used for this purpose are accelerometers and gyroscopes; however, wefound out that a gravity sensor has significant potential to be utilized aswell. In this paper, we propose a novel method to recognize activities usingthe combination of an accelerometer and gravity sensor. We design a simplehierarchical system with the purpose of developing a more energy efficientapplication to be implemented in smartphones. We achieved an average of 95% forthe activity recognition accuracy, and we also succeed at proving that our workis more energy efficient compared to other works."

"Avacuum drying system is being designed and developed at National Institute ofVacuum Science & Technology (NINVAST) to dry various materials under vacuumconditions. Its performance and capabilities are tested by carrying outdifferent experiments on green (freshly cut) wood samples of Poplar andEucalyptus with dimensions of 990.6 mm x 76.2 mm x 25.4 mm and 469.9 mm x 50.8mm x 25.4 mm, respectively. These samples were dried from green moisturecontent (MC) 78% to 10% by this system at ultimate vacuum of about 1.6 x 103pascal and at a temperature ranging from 35oC to 55oC forabout 20 hrs. Drying quality tests included: prong test, warp measurement,surface checking and moisture content measurement, which were all performed.The resulting wood samples showed no dislocation and no excessive stressbuildup. If compared to ordinary drying process, the vacuum drying is rapid andthe drying rate increases with rise in temperature. The designed system isbeneficial for commercial use."

"Todevelop seismic design criteria for buildings, seismic hazard analysis is required to estimate the ground motionintensity with criteria such as peak groundacceleration (PGA). The seismic hazard can be analyzed by using two approaches: deterministic seismic hazard analysis (DSHA) andprobabilistic seismic hazard analysis (PSHA). In these two approaches, theseismic hazard is evaluated from past earthquake events and active faults data. In Thailand, seismic hazard is classified in the low lying regions; however, in recently years,earthquakes have occurred frequently in the North of Thailand. Toprevent and reduce damage due to earthquakes in the future, determinationof seismic hazard is needed. Thisresearch proposes a deterministic seismic hazardmap evaluated from nineteenactive faults affectingThailand. Two types of active faults are considered: first, an active fault in a subduction zone and second, a crustal fault. The seismic hazard is evaluated by using a groundmotion prediction equation (GMPEs). Four GMPEs are weighted equally forseismic crustal fault, and two GMPEs are weighted equally fora seismic subduction zone. The hypocentral distance isused to evaluate the seismic hazard for all ground motion prediction equations.The Northern part and the Western part of Thailand are high seismic hazardregions, because there are active faults with the large possibility of earthquakes of a maximum magnitude. The seismichazards in the North, West and Northeast of Thailand are about 0.60 g.The seismic hazard in Bangkok is about 0.25 g due to the Three Pagoda fault and Sri Sawat fault. The seismic hazard in the South of Thailand is about 0.40 g."

"Tesis ini membahas tentang faktor-faktor yang mempengaruhi kinerja Program Insentif Percepatan Difusi dan Pemanfaatan Iptek dari mulai faktor input sampai dengan outcome dengan menggunakan metode logic model. Penelitian ini menggunakan pendekatan kualitatif yang bersifat deskriptif analitik. Hasil analisis menunjukkan bahwa faktor input yang sangat berpengaruh dalam pelaksanaan Program Insentif Percepatan Difusi dan Pemanfaatan Iptek adalah sumber daya manusia, proposal, waktu serta mitra peneliti. Seleksi proposal yang dilakukan oleh tim penilai independen harus memenuhi syarat dan ketentuan yang sudah ditetapkan oleh Kemenristek. Outcome jangka panjang yang seharusnya bisa tercapai ternyata masih membutuhkan proses yang lama dan panjang serta memerlukan dukungan dari pihakpihak terkait. Hasil penelitian ini menyarankan agar proposal yang diterima diprioritaskan pada proposal yang mempunyai potensi tinggi untuk ketercapaian outcome jangka panjang. Disarankan pula agar Kemenristek berkoordinasi dan bersinergi dengan kementerian terkait lainnya untuk mendukung kebijakan mengenai tindak lanjut penerapan teknologi serta transfer teknologi yang dihasilkan dari pembiayaan Program Insentif Percepatan Difusi dan Pemanfaatan Iptek ini.

"The choice among modes of intercity transport depends on conditions of not only intercity transport modes but also intracity transport in both the departure city and the arrival city. Intracity transport conditions might be advantageous for one intercity mode and disadvantageous for others. Intercity and intracity transport conditions are complex and need to be approached systemically. This study proposes an approach based on the passengers? preferences. The logit model was adapted to evaluate the transport modes? choices in competition. This model is called the ?Adapted Mixed Multinomial Logit Model? (AMML). It was applied on the Jakarta-Bandung corridor in both directions. It contributes to a complete approach for intercity transport mode choice by considering the influence of the intracity transport conditions in both the departure and arrival cities. The results proved that the choice of intercity transport mode depends not only on its own quality of service but also, importantly, on that of the intracity transport systems."
