This paper presents the design of non-split drain MAGFET for high sensitivity magnetic device. The structure is split drain MAGFET that has no gap between drains so drain is only one drain that has split contacts within a drain. It is proved that MAGFET is not necessary to design by split drain with gap between them. The sensitivity is the highest for non-split drain structure. This study compares sensitivities of the two structures with gap between drains of 3, 2, 1 and $0 mu mathbf{m}$ at 0.25 mA, aspect ratio $mathbf{L}/mathbf{W}=1$, which are 0.0326, 0.0389, 0.0481 and 0.0595 T−1, respectively. The relative sensitivities ($boldsymbol{S}_{boldsymbol{r}}$) of non-split drain are also highest at other aspect ratios which are 0.0003, 0.0036, 0.0092 and 0.0231 T−1 for $mathbf{L}/mathbf{W}=0.2$ and 0.0182, 0.0264, 0.0338 and 0.0479 T−1 for $mathbf{L}/mathbf{W}=0.6$, respectively. The non-split drain MAGFET is a new design for highest sensitivity. The non-split drain design is the smart way for high sensitivity MAGFET.
本文介绍了一种用于高灵敏度磁性器件的非劈裂漏极磁场效应管的设计。该结构是分体式漏极磁场效应管，在漏极之间没有间隙，因此漏极只是一个漏极，在漏极内具有分体式触点。证明了磁场效应管没有必要采用缝隙式漏极设计。非分体式排水结构的灵敏度最高。在0.25 mA、宽高比为$mathbf{L}/mathbf{W}=1$时，两种结构的灵敏度分别为0.0326、0.0389、0.0481和0.0595 T−1。当宽高比为$mathbf{L}/mathbf{W}=0.2$时，非分体漏的相对灵敏度($boldsymbol{S}_{boldsymbol{r}}$)也最高，分别为0.0003、0.0036、0.0092和0.0231 T - 1， $mathbf{L}/mathbf{W}=0.6$时，相对灵敏度分别为0.0182、0.0264、0.0338和0.0479 T - 1。非分体式漏极磁场效应管是一种具有最高灵敏度的新设计。非分体式漏极设计是高灵敏度磁场效应管的聪明方法。

Stereo matching is one of the most important task of stereo binocular vision system. This paper will discuss stereo matching method used in tsunami warning system which measures tsunami based on stereo binocular vision system. To solve the problem of lacking obvious feature points in sea surface image, the paper extracts sea waves out from sea surface image to form feature points and integrates sea waves' size, shape, brightness, location and lengths in four orientations to distinguish each point and finishes stereo matching of tsunami warning system by the feature points and their features.

A new method for highly secured wireless transmission was proposed as optical asymmetric key cryptography in RoFSO. The optical equipment used for handling high security communication was a PANDA ring resonator and an add/drop filter. A PANDA ring resonator used the dynamic behavior of bright-bright soliton collision. The outputs of the dynamic states were used to form key suppression and key generation as a communication security application. An add/drop filter was used to recover the optical key from suppression and generate an optical asymmetric key (key for sending and key for receiving). Simulation results showed that the proposed design achieved optical asymmetric key cryptography in RoFSO. The sender's data was not perceived by an interferer because the ciphertext data signal was covered by a noiselike signal in a frequency domain of tunnel's form like a noiselike signal.

This paper presents performance comparison between a two-switch and RCD clamp forward converters. The performance comparison is carried out through experimentation on the two prototype circuits, which have the same circuit specifications and similar component values. Aspects to be compared include voltage stress of switching components, output voltage regulation, transient response due to a step-load, and efficiency. Test results show that, while the two converters exhibit equal performance on output voltage regulation, the two-switch forward converter has a lower voltage stress on power switching devices, faster transient response, and higher efficiency than the RCD clamp forward converter.

We investigate sound absorption characteristics of husk embedded into different sizes of holders made of metal-meshed frame and plastic net. Five thicknesses and four densities of husk panels are studied for their sound absorption property. The husk panels, without binding chemicals, display strong sound absorption, 0.97, at specific frequencies that are comparable to that of commercial one at the same thickness. On average, the sound absorption is approximately 0.9. This study shows that husk, by product of rice milling process, could be used as natural sound absorbing material.

Walking outside in Thailand is difficult for the visually impaired because obstacles on sidewalks such as uneven pavements, light poles and billboards. These obstacles can cause frequent accidents. Although some advanced technologies can facilitate the visually impaired to walk safely, accidents still occur. Most currently technologies focus on detection of ground-level obstacles and require much processing time. There are few devices constructed to prevent accidents that happen to the head. This study is a development of a collision warning device to alert the visually impaired of obstacles that their head may crash into while walking. UltraSight consists of an Arduino, an ultrasonic distance sensor, and a PIR motion sensor. Its operation was robustly designed based on the concepts and theories of walking behavior. It was tested in a laboratory equipped with several mock poles and other obstacles. UltraSight avoided 96% of them. A future design will be a similar device and attached on the head of user.

Conversations between a person with severe hearing impairment and a hearing person is difficult because people who know sign language are rare. Therefore, to facilitate the conversation, we design and develop a portable dialogue box that can be used without an interpreter. The system detects sign language of a deaf person by capturing hand images with a camera. The images are pre-processed and the histograms of oriented gradients (HOG) are extracted as image features. A multi-class support vector machine uses the HOGs as inputs to classify the alphabets. The vocal reply from a hearing person is received through a microphone and interpreted via Google cloud speech API. Both parts are processed by a microcomputer to produce messages of the conversation. The dialogue is displayed on the graphical user interface. The system can also record the conversation logs into the database.

In this paper, the performance evaluation for Internet of Things based on blockchain Technology is proposed. In a blockchain network, all IoT devices communicate and synchronize with each other and allow device to transact with each other directly without the need of trusted intermediary. IoT devices have a smart contract associate with them which are deployed on the blockchain network. User or device who wish to use a service can transact to smart contract that associated with IoT device. Moreover, all transactions of IoT device, device-to device or human-to-device, will not only permanently store on Blockchain network but also gain the security and privacy of them. In this implementation, a private Ethereum network is chosen to use as a blockchain platform and the raspberry pi act as a lightweight node to transact with a smart contract in a full node which install on PC desktop. In addition, the performance evaluation of two realistic traffic flow, store and access transactions, such as latency, execution time and throughput are highlight.
