The bi-modal vehicle is composed of two car-bodies and three axles. Each axle of the vehicle has an independent suspension and all wheels are steerable. Since the bi-modal vehicle has longer wheelbase than most urban buses, the All-Wheel-Steering(AWS) system is adapted for to ensure safe driving and proper turning radius on a curved road. This paper proposes an AWS control algorithm for stable driving of bi-modal vehicle. Steering angles and directions of each axle of bi-modal vehicle changed according to the driving environment and steering modes. In the case that front and rear axles should be steered in opposite directions is a negative mode, and the other case that the axles should be steered in the same direction is a positive mode. For example, in the positive mode, front and real axles are steered in the same direction, while in the negative mode, they are steered in the opposite direction. A multibody model of the vehicle is used to verify the performance of the steering algorithm and simulation results of 2WS are compared with those of AWS under the same condition.

$Bi_2Te_3$-based alloys have been intensively investigated as active materials for thermoelectric power generation devices from low-temperature (< $250^{\circ}C$) waste heat. In the present study, we fabricated Pb-doped, p-type $Bi_{0.48}Sb_{1.52}Te_3$ polycrystalline bulks by using meltsolidification and spark plasma sintering techniques, and evaluated their thermoelectric transport properties in an effort to develop optimized composition for low-temperature power generation applications. The electronic and thermal transport properties of $Bi_{0.48}Sb_{1.52}Te_3$ could be manipulated by Pb doping. As a result, the temperature for a peak thermoelectric performance (zT) gradually shifted toward higher temperatures with Pb content, suggesting that thermoelectric power generation efficiency can be enhanced by controlled Pb doping.

본 연구에서는 hexagonal-ferrite에서 NiO, CuO의 몰비와 B-Bi-Zn 첨가제에 따른 미세구조, 밀도 흡수율, 수축율, 주파수에 따른 투자율 등의 특성을 관찰하여 수 GHz대역의 고주파 침 인덕터용 재료로서의 가능성을 확인하고자 하였다. 투자율의 측정은 impedance analyzer 와 network analyzer를 이용하여 100kHz∼3GHz 대역까지 실시하였다. 특성의변화를 살펴본 결과 사용된 B-Bi-Zn 유리분말은 전극돠의 동시소결이 가능하게 보였으며, 복수투자율의 결과에 의하며, 1.8GHz까지는 그 값이 변화를 보이지 않고 일정하였고, 복소투자율의 허수값이 최고값에서 나타나는 공진주파수는 2 GHz 부근에서 관찰되었다.
