No doubt that more vast data and precise values are required for the detailed and accurate analysis result. People's expectation for the output of space application goes higher, and consequently satellite memory system has to process massive data faster. This paper reviews memory systems of KOMPSAT (Korea Multi-Purpose SATellite) series and try to find a suitable memory system structure to process data more faster not at device level but at system level.

Although it is widely accepted that a fire can occur due to electrical causes even when an engine stops, there is little introduction of detailed case analysis. This study analyzed a fire case caused by an electrical cause during engine stopping at parking lot in detail. Moreover, it was revealed that the fire was mainly caused by design defect.

Termination cryostat for 22.9kV, 1.26kA-class HTS power cable has been designed. The cryostat consists of vacuum vessel, liquid nitrogen vessel, current lead and HTS power cable. The current lead and the HTS power cable are connected in liquid nitrogen vessel cooled by forced-circulation subcooled liquid nitrogen. The maximum total heat load of this cryostat is expected to be 150w. In this paper, the detailed design of the termination cryostat is mentioned.

Recent market competition forces the price to be determined in the design stage so that the design would meet the target price of the product. However, most commercial PDM(Product Data Management) systems currently in use lack such a cost estimation function. In this paper, we propose detailed structure and functions of a new approach to estimate the cost of new products using integrated BOM in PDM. Such system will reduce the total life cycle cost of the products to be designed.

In this paper we present a microprocessor-based interpolator using algebraic arithmetic method. The interpolator consists of 2900 "bit-slice" microprocessor chips and 0.5K ROMs of 36-bit microprogram memory. The system design is an instuction-data-based architecture with 250ns cycle time. A significant feature of the interpolator is that it has flexibility, very fast interpolation speed of 250 K pulses/sec, and performs additional functions simultaneously. Throughout the paper detailed explanations are given as to how one can design the hardware and software, and experimental results are presented.presented.

In aerodynamic design of centrifugal compressors, impellers are designed through preliminary design and blade profile generation. In order to find out faults of the initially designed impellers, the detailed informations about internal flow phenomena such as pressure distribution, flow separation, blade loading, etc are essential. These informations can be acquired with flow measurements or computational flow analyses. In this study, we calculated 3-D viscous flow in 4 back-swept impellers which were designed in our laboratory, and analyzed the flow characteristics which influence the performance of impellers.

A detailed investigation of a reed resonance for a vertical pump design has been conducted. The structural features of this class of pump lead to typical dynamic characteristics. Of particular importance is the fact that the pump assembly is suspended on a high column above the floor with a heavy motor on the top. Considerable amount of mass forces is involved and the vibration can cause damage to the pumps or to the foundation. It is shown that the reed resonance of the pump-motor system plays important role for design and troubleshooting purposes.

This paper describes the architecture, the basic operation principle and detailed experimental results of digitally programmable high-voltage generators that can be used in monolithic low-power high-voltage bistable LCD drivers. Two different design approaches, depending on whether the application allows the use of external passive components or not, are analyzed.

The individual control of machines or processors is subordinate to the management of the entire manufacturing production function. This distinction is necessary in order to provide the appropriate separation of and detailed focus on process activities while still providing acceptable interfaces for the upload of data and the download of instructions, recipes, or commands.
