In this study, a technique designed to estimate of the autonomic nerve activity with a facial thermogram has been conducted a research and development. Workers feel more mental work-load (: MWL) by advanced information society. Preventing human errors and health hazards with MWL is important. Research activities about MWL, there is the method using thermogram. Thermogram can be taken by non-contact thermometer easily such as a thermography. It can take in the shop floor or life log. But the method needs to measures time-series data at all process of experiment. In addition, if a subject is out of focus of thrmography, it is difficult to estimate MWL. Therefore, measurement environment is limited. In this study, new method are proposed to estimate of the autonomic nerve activity with facial thermogram. If new method with facial thermogram can estimate MWL to high quality, it can use in various situation. Thermograms was taken when a subject solved the issue of a mental arithmetic calculation. And the proposed method has been analyzed by thermograms. As a result of this experiment, proposed method is more sensitive than past technique.

Mobile phone has played an important role in daily life. Many applications on mobile phone can provide location service to user. A GPS sensor provides highly accurate localization system in outdoor environment but low accuracy over an indoor scenario because obstacles and mainly infrastructure of building block a GPS signal from GPS satellites. Moreover, GPS cannot determine a current floor that mobile phone is located on. Many indoor localization approaches have been proposed to address this problem. The approaches require back-end servers, which have high cost of hardware, software and maintenances to support localization processing. In this paper, we propose a low complexity floor localization algorithm. Our floor localization can be done on mobile phone and does not need any support from back-end server. The algorithm uses Wi-Fi access points that the mobile phone can detect as an input to determine current floor of the mobile phone. In addition, our proposed floor localization algorithm provides up to 90.83% of accuracy.

This paper presents a power transfer technique for Inductively Coupling Power Transfer (ICPT) Systems by searching suitable switching frequency based on the maximum DC power supply current. To verify the proposed control strategy, an ICPT system is implemented by a full-bridge resonant inverter that is compensated its switching losses by capacitors on both primary and secondary sides. The analysis and design techniques for the ICPT system are presented. By using the proposed control method, the maximum power transfer can be accomplished, even though the shape of coil, the capacitor compensation topologies and air-gap are changed. The experimental results prove that the maximum power transfer can be successfully achieved.

The paper presents analysis of the wave propagation through down-tapered three-layer liquid crystal optical fiber in respect of power confinement due to the hybrid modes supported by the guide. The inner two regions are homogeneous and isotropic dielectrics whereas the outermost layer being composed of radially anisotropic liquid crystal material. It has been found that the guide supports relatively very high amount of power in the liquid crystal region, which indicates the possible use of such microstructures in varieties of optical applications. The effects on confinement due to the positive and the negative (illustrating the taper type) values of taper slopes are reported.

This article presents the enhancement of bandwidth for rectangular slot antenna with an H and T-shaped slot tuning. The bandwidth was increased from the original antenna by using the T-shaped slot tuning technique and adding the tuning stubs on the both sides of ground plane. The proposed antenna can be applied to ultra-wideband frequency range between 3.1-10.6 GHz based on the IEEE 802.15.3a standard with compact antenna dimension of 30×35 mm2. In designing the antenna, the simulation software, CST Microwave Studio, was used to study and analyze various parameters and characteristics. The simulation and measurement results were agreed fairly well and they showed that the impedance bandwidth was about 130.49% (2.82-13.41 GHz) which was increased from the original antenna by 53.35%, with the average gain of 4.76 dBi possessing bi-directional radiation pattern.

In this paper, a new expression for oscillating amplitude of CMOS LC differential oscillator is derived. Contrary to the conventional expression which was derived by assuming that the current from sourced coupled pair flowing though LC tank is a square wave, the proposed expression is derived by assuming that such current is a clipped sinusoidal, which is more in line with the real situation. By comparing to the simulation results, it was found that the new expression of oscillating amplitude is more accurate than the widely used conventional expression.

This work presents the combining of two methods, which are discrete Fourier transform spread (DFT-spread) and 2×2 space time block codes (STBC), to improve the system performance for polarization division multiplexing (PDM) coherent optical orthogonal frequency division multiplexing (CO-OFDM) communication systems. The system performances are generally measured by the unit of bit error rate (BER). For 64-QAM, the communication length of 850 km can be achieved at the forward error control (FEC) limit.

Drivers error is one of the key factor that contributes to road traffic accidents, often in the form of distracted driving which is when drivers are engaged in a secondary task other than driving. Other than the traditional calling and texting, the multi-capabilities of modern smartphones nowadays enable us to realise a wide range of tasks such as emailing, surfing the net and social networking. However, these activities can be considered road hazards if performed while driving. The main objective of this paper is to conduct a study of the impact of smartphone usage on the driver behaviour on urban road segments using real world data. In total, three activities are deployed for participants to undertake. These are conversing on the phone in handheld and handsfree modes and using instant messaging application. Findings from this study revealed that all of the three activities involving smartphone usage require drivers to compensate their driving in order to maintain the safety level at the “feel safe” zone. The phone activity that involves instant messaging has shown to require the highest attention level from a driver, and consequently the compensation level is at the highest. Taking all aspects into considerations, a figure of merit in terms of the compensation level was proposed, which can be used as an indicator to characterise the driving performance for each distracted phone activities.

One of the major issues of multiple-campus university is the distance between campuses which makes the collaboration between campuses inefficient. Each time the conference is occur, the most budget are spent on the transportation, time, and paperwork. In this study, we redesign the electronic conference system for multiple-campus universities. We chose our university (Silpakorn University) as a case study. Moreover, we also make a good use of tablet personal computers and laptops with touchscreen input (a.k.a. Ultrabooks) to enhance the conference experience. The new minimal and simple user interface design make a larger number of directors decided to use this system 275% than the previously developed system. They're also satisfy with the simplicity design (Average score 4.50) and enhance the conference efficiency of the director (Average score 4.43). The newly developed system also makes the conference to “paperless conference” and significantly reduces the transportation and paperwork cost on each conference by approximately USD 188.96 or USD 4724.05 per year.

In this paper, we proposed an unsupervised algorithm to identify the flooded areas from synthetic aperture radar (SAR) images based on texture information derived from the gray-level co-occurrence matrices (GLCM) texture analysis. Here, five GLCM features, namely, energy, contrast, homogeneity, correlation and entropy, are extracted from a SAR image. These features are input to an image segmentation algorithm using a level set method to identify flooded and dry areas. Experiments were conducted on the RADARSAT-2 images of severely flooded areas near Chaopraya rivers, Thailand, in 2011, for which contemporaneous ground data exists for validation. Our results demonstrate that the proposed algorithm is able to successfully segment various flood regions and achieve improvement over existing published unsupervised algorithms.
