In the wireless communication protocols, a network device is responsible for the operation of lower-layers. The network device consists of hardware and software modules, so it can be designed using system-on-chip simulator. The simulator design needs the support of a network simulator as well as system-on-chip simulator, because the network device interact with various higher layer communication protocols. Therefore the co-simulator can become a development environment of the network device through the combining of them. In this paper we propose a co-simulator combining these two simulators. The proposed co-simulator does not degrade performance due to integrations. Also, it is easy to integrate them because the implementation of the kernel is independent.

A soft error rate (SER) simulator for DRAM was developed. In comparison to the other SER simulator using device simulator or Monte Carlo simulator, the proposed simulator substantially reduced the CPU time using an analytical model for the alpha-particle-induced charge collection. By analysing the soft error modes in DRAM, the bit-bar mode was identified as the main cause of soft error. Using the new SER simulator, SER of 256M DRAM was investigated and it was found that the storage capacitance had a 5fF margin.

In this study, we developed a PC - based motorcycle simulator based on the development technology of the virtual patrol motorcycle training system. In order to get the impression that the motorcycle simulator is operating in a realistic way, it is important to have a reliable signal transmission and operation feeling between the driver and the simulator. In order to achieve this, we developed a system that can apply the sub-systems of the actual vehicle to the motorcycle simulator in order to generate the same operation feeling as the actual vehicle. Based on these results, We have developed a method for generating a feedback queue. Vehicle dynamics simulates real-time vehicle motion by receiving input from a steering wheel, accelerating / decelerating pedal, etc. operated by a driver on a vehicle simulator and transmitting the result to a visual and acoustic system, It is the central element of the simulator to generate. I want to summarize the main requirements of simulation dynamics.

In this paper, an Automatic Terrain Following (ATF) Simulator using Digital Terrain Elevation Data (DTED) was proposed. This ATF Simulator consists of a Flight Simulator, a Radar Simulator, and a Terrain Following Computer (TFC) Simulator. DTED and radar scan data generated with DTED were used as the terrain information necessary for terrain following. The ATF Simulator provides three modes of operation: a passive mode that uses DTED, an active mode that uses radar scan data, and a hybrid mode that uses both. We developed an ATF Simulator that could reduce the cost and time required to develop a terrain following system using the LabVIEW development environment and the MATLAB App Designer development environment. It was verified by confirming that the ATF Simulator met all functional requirements.

In this paper, it is proposed that the effects of simulator sickness due to scene movement in ship handling simulator can be measured by using center of pressure (COP) and a simulator sickness questionnaire (SSQ). For experiments of simulator sickness, twelve participants are exposed to scenes movement from ship handling simulator according to three steps of sea states. During experiments, COPs for subjects are measured by force plate. After exposure to scenes movement, subjects describe their sickness symptoms by answering the SSQ. Throughput analysing the results of scene movement, SSQ, and COP, the relation between the simulator sickness and COP is investigated. It is suggested that formulations for SSQ score and COP with respect to sea state are obtained by the curve fitting technique, and the longitudinal COP can be used for measuring the simulator sickness.

In this paper, we reviews the need and contents of aerodrome control simulator for air traffic controllers' training. In the view of managing the aviation safety, the departure and landing phases of aircraft are very important, because more than 60% of aircraft accidents and incidents have occurred in the take-off and landing phases. According to the benchmark each as practice type, simulation device and fidelity of reality of the air traffic control simulator, we have evaluated the implementation level of the domestic air traffic control simulator and checked up the current simulator's problems through the air traffic controllers' survey. Therefore, we suggest to the direction of developing a HI-FI simulator for aerodrome controllers.

This paper describes a testbed that was designed and implemented for the development of KSLV-II onboard equipment simulator. It used the CPCI-based industrial hardware system for scalability and the QNX real-time operating system for reliability and real-time simulation. In addition, a real-time application under QNX for function simulations of the KSLV-I PDU was developed and it was verified through interface experiments with KSLV-I upper-stage test equipment. The implemented simulator testbed will be used to verify the development feasibility in the design and development phase of a real KSLV-II onboard equipment simulator.

본 실험은 자동차 시뮬레이터의 속도 변화(40, 70, 100km/h)와 롤러코스터 시뮬레이터의 운동성 구현 방법(washout 필터 적용, washout 필터 비적용) 에 따른 인간 감성을 탑승자의 주관적 평가를 통하여 비교 평가하였다. 자동차 시뮬레이터, 롤러코스터 시뮬레이터 실험은 각각 건강한 20대 남자 12명, 8명을 대상으로 simulator sickness, 쾌적감, 긴장감, 각성감, 속도감에 대한 주관적 평가를 실시하였다. 결과, 자동차 시뮬레이터에서의 저속주행보다 운동형태가 다양한 롤러코스터 시뮬레이터 주행시 쾌적감, 긴장감, 각성감, 속도감이 유의하게 높았다. 즉 자동차 시뮬레이터에서는 주행시 주행속도가 증가함에 따라 운전자의 감성의 정도는 상승하였고 시뮬레이터간 비교에서는 자동차 시뮬레이터의 저속 주행에 비해 롤러코스터 시뮬레이터 주행시 감성변화는 더 컸다. 이상에서 시뮬레이터 구현 방법에서 속도 요소와 다양한 운동성 요소가 탑승자의 감성에 영향을 주는 것으로 나타났다.

A flight simulator is a device that allows pilots attain proficiency of various situations and a sense of flight, and as interest in scientific training increases in modern aviation, aviation training organization develop and operate simulators. Therefore, in this study, the process of developing a motion-based helicopter simulation Training Device using a commercial program. Citing previous studies, the specificity of helicopter flight education and the positive effect of motion simulators were confirmed. In addition, the design and program of the motion device were studied in the process of checking the configuration and current regulations of flight simulation training devices and developing a helicopter motion simulator. A motion program was set based on the system design and structural design of the flight simulator, and data received from the flight simulator was identified to confirm the expected operating shape. Through this study, we intend to create a positive expected effect on pilot training by completing a motion-based helicopter simulator.
