In this paper, the techniques for implementing the dashboard functions of a SHEV bus are development by using a touch panel. The algorithms for controlling linearly the angle of each gauge according to the measured sensors values. The hardware technique presentation and the development for implementing the On/Off information of each telltale lamp in the touch panel. The system is implemented by the 32-bit DSP, and it is installed and tested on the real SHEV bus. Also on/off switching status of all telltale lamps cab be investigated through the touch panel.

AVLS is nowadays pretty considered on one of important parts in telematics service with a computerization of vehicle. However, with an implementation of commercial OS, individual OS and firmware on AVLS terminals, the cost and developing period are significantly increased. In this paper, we present the effective log-file creation methode about automobile status and location information within a restricted memory through designing AVLS terminals based on embedded linux. The proposed method shows 0.8% better performance on bzip2 compressor comparing to gzip compressor in the compressibility. In addition, bzip2 is faster than gzip about 2.14 times in the speed of compression.

This work describes a design and implementation of the level & flow rate control system by using a single-chip microcontroller. The proposed model system is designed based on the use of the single-chip microcontroller 8031 with the EPROM emulator for programming the computer software. The microcontroller reaches the input level and flow signals from the level sensor and the turbine flowmeter, respectively, via the signal conditioning circuits and A/D converters in order to calculate the control signal. Moreover, the status of the process variable can easily be set up and controlled by program monitoring through the emulator, and can be graphically displayed on the computer screen. Experiment results were carried out which can be ...

A complete code-package for gyrotron simulation to analyze its performance is under development in UNIST, Korea. We first time report the present status of the code-package named as UNIST Gyrotron Design Tool (UGDT). It can perform design simulations for gyrotron's interaction cavity, RF window, and the essential mode calculations including the study of mode competition. We will discuss about its salient features, theory, numerical implementation, and its calculation result for 95 GHz UNIST Gyrotron. Moreover, we will validate its capability to perform the mode competition calculation for fundamental and second harmonic modes.

National Competency Standard(NCS) is a national organization that organizes the knowledge, skills, and quality required to perform duties at industrial sites by industry sector and level. As NCS was developed and adopted as part of the government's implementation of capability-oriented society, the construction industry is also fully applying NCS to the curriculum and training. This study investigated and analyzed the problems of NCS development in construction work field through prior research analysis and experts interview and derived problems such as discrepancies in classification system, lack of connectivity with curriculum, and lack of effectiveness in revising NCS in construction work field. Further research is thought to be necessary for the establishment of the development system reflecting the construction characteristics in the future and for the presentation of practical improvement directions.

In this paper, the Embedded MEMS system to the power apparatus used Edge Impulse machine learning tools and therefore an improved predictive system design is implemented. The proposed MEMS embedded system is developed based on nRF52840 system and the sensor with 3-Axis Digital Magnetometer, I2C interface and magnetic measurable range ±120 uT, BM1422AGMV which incorporates magneto impedance elements to detect magnetic field and the ARM M4 32-bit processor controller circuit in a small package. The MEMS embedded platform is consisted with Edge Impulse Machine Learning and system driver implementation between hardware and software drivers using SensorQ which is special queue including user application temporary sensor data. In this paper by experimenting, TensorFlow machine learning training output is applied to the power apparatus for analyzing the status such as "Normal, Warning, Hazard" and predicting the performance at level of 99.6% accuracy and 0.01 loss.

The article analyzes the theoretical aspects of the relationship between the right to medical secrecy and the employer's right to receive information on the employee's state of health, resulting in a more complete description of the implementation of the right to medical secrecy and the employer's right to information on the employee's health state and the possibilities of protecting violated rights. The limits of permissible restrictions on the right to secrecy of health in terms of ensuring the person's performance of their job function have been clarified.
