Sign language uses gestures instead of speech sound to communicate. However, it is rare that the normal people try to learn the sign language for interacting with deaf people. Therefore, the need for a translation from sign language to written or oral language becomes important. In this paper, we propose a prototype system that can recognize the hand gesture sign language in real time. We use HSV (Hue Saturation Value) color space combined with skin detection to remove the complex background and create segmented images. Then a contour detection is applied to localize and save hand area. Further, we use SURF algorithm to detect and extract key point features and recognize each hand gesture sign alphabet by comparing with these user image database. Based on the experiments, the system is capable to recognize hand gesture sign and translate to Alphabets, with recognize rate 63 % in average.

Due to the wide usage of very low frequency (VLF) wave for research on natural phenomena such as lightning, earthquake, and weather, a receiver for VLF application particularly with high-gain is absolutely required. This paper discusses about designing, realizing and characterizing a high gain radio frequency (RF) amplifier for VLF receiver application. The proposed amplifier which is designed using a junction field-effect transistor (JFET) of 2SK170 and an operational amplifier (OpAmp) of OP27 is intended to work at frequency range below 50kHz. After achieving the optimum design, the hardware realization is then carried out by deploying the designed amplifier on a printed circuit board. From the experimental characterization, it shows that the measured gain of realized amplifier at frequency of 19.8kHz satisfies with the design criteria and is 46.003dB with 1-dB compression point of -24dBm.

This paper aims to look at the distribution pattern of the magnetic topology resulting from two different axial machines which are dual rotor with an internal stator (RSR) axial generator and dual stator with an internal rotor (SRS) axial generator. The simulation was performed with the finite element method software FEMM 4.2 using symmetry analysis which considers all parts of identical geometry. In this software will see the pattern of the magnetic flux distribution as well as the effects on axial machine. The output obtained from the magnetic flux distribution pattern can be either air-gap magnetic flux density, anchor reaction flux density, induced electromotive force and the electromagnetic torque generated.

A high transient current occurring when starting up an induction motor can lead to voltage dip. This paper proposes a method of induction motor soft-starting by using magnetic energy recovery switch (MERS). The MERS is a series compensation device and is able to control motor terminal voltage. The design of MERS control system is described. The starting current produced can be controlled by setting up the MERS firing angle. Experimental results confirmed that starting current can be reduced by applying MERS in series with induction motor.

Ever since its first development, Fuzzy Logic Controllers (FLC) have been popular among the practitioners due to its robustness, interpretability, and especially its ability to handle imprecision. Many constructions of these controllers are still heavily dependent on the presence of experts' knowledge. This drawback has been investigated by many researchers, resulting in several methods integrated into the construction of FLC. This paper presents a novel method to generate FLC with the minimum involvement of experts. The method integrates Genetic Algorithm (GA) into the design process. The concept of gene pool, rule filter, and two levels of encoding were devised for the method. Simulative tests to control a nonlinear single tank system and a benchmark inverted pendulum system were undertaken. The results show the performance of the proposed method to create FLCs for both systems with minimum need of prior knowledge.

This paper describes a monitoring system based on the cooperation of a surveillance sensor and a mobile robot. Using a depth camera which acts as the surveillance sensor, the system estimates the pose and orientation of a person utilizing a skeleton-based algorithm. When the person fell down, the sensor sends the person's pose and orientation information to the mobile robot. The robot determines the possible movements and strategies for reaching the fallen person. The robot then approaches the person and checks the vital condition whether the person is breathing, and the recognition result is notified to a hand-held device. Experiments on our monitoring system confirm a successful series of the autonomous operations.

Tourism is closely connected with mobile activities. People go the tourism attractions by doing mobile within city or even country. As a tourist, mobility means put some risk for the convenience of sightseeing. For example, when the visitor visits the attractions might feel uncomfortable because crowd of people, closed attractions, or meaningless unguided tour. This paper describes an alternative approach to improve the tourism experience through mobile software technology. The research proposes a model namely mobile tourism service model. Mobile tourism service model is designed to fulfill the gap between the tourism experience and the contextual of the attractions. As a benefit, mobile tourism services model will guide a content developer to create mobile application that improve the tourism user experience based on contextual, culture, and live information.

Smile detection received a enormous attention due to its famous application as a `smile shutter' in digital cameras. Edge Orientation Histograms (EOH) is one of the possible feature descriptors in a smile detector. This paper presents an evaluation of the use of Edge Orientation Histograms in a lip image based smile detector. The system built in this paper aims to discriminate lip images depicting a smile (including thin smile and broad smile) from lip images depicting non-smiling expressions. By dividing the lip images into 2 × 4 cells, and using 5° histogram bin size, we achieved 87.8% arithmetic means of accuracies. The experiments show that it is recommended not to use spatial binning that is too small. However, it is recommended to use fine orientation binning. Finally, it is recommended to use all orientation bins as features.

Availability of wind speed information is of great importance for wind energy conversion systems (WECS) to extract maximum energy from wind. Most controllers in WECS employ anemometers to measure wind speed. To obtain adequate wind speed information a number of anemometers is required and needs to be installed properly surrounding wind turbine. This paper presents fuzzy logic principles for estimation of wind speed on the center of the wind turbine. The principles are inferred heuristically from a typical wind turbine power curve. The proposed principles have been simulated to estimate the wind speed on the center of the wind turbine during the WECS operation. The simulation results show that the wind speed could be well estimated under the wind speed variations.

In this paper, we report the development of water tank for underwater acoustic communication. Compared to most of underwater test tank, the tank may be considered as mini in term of its size. However, the test tank is intended to serve as controlled environment to develop a theoretical model and its validation experimentally before full-scale test at sea. We present on how to analyze the physical characteristics of the test tank with respect to salinity and temperature affected to speed and pattern of propagation waves. We designed the test tank made of 12mm thick of glass with dimension 2 × 1 × 1 in meter, then we placed corrugated sponges inside the walls to reduce the echo from signal that we generated. The measurements were conducted by placing array of hydrophones and analyze the propagating waves in fresh water with variation temperature 15°C, 20°C, 25°C and 30°C to simulate depth. In term of salinity we fixed at room temperature 30°C and varied the salinity of 3.1%, 3.2% 3.3%, 3.4% and 3.5%, respectively. The results showed that the sound propagation characteristics are in agreement with previous studies. This may suggest that the test tank may serve as small scale underwater acoustic experiment with controlled environment.
