UV- and thermal-curing behaviors of dual-curable adhesives using divinyl sulfone
임승호,김하은,황태성,김정수,장영욱,김동현 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-
The dual curable adhesive was prepared using a sequential dual curing system based on the thiol-acrylate-epoxy formulation. The curing proceeds the UV-curing of thiol-acrylate and the thermal-curing of thiol-epoxy which requires a photo-initiator and a catalyst, respectively. The presence of sulfone in the thiol-acrylate reaction shows a high reaction selectivity and reaction rate. Thiol-acrylate-epoxy resin was synthesized using thiol monomer with four functionality, diacrylate monomer, and bisphenol A diglycidyl ether. The chemical structure of dual curable adhesive was characterized using a fourier transform infrared spectrophotometer. Thermal stability of dual curable ones was analyzed by thermogravimetric analysis. The adhesion strength and peel strength of dual curable ones were compared with using the universal testing machine.

Power spectral density analysis has been used to analyze ride quality of a vehicle traveling on a rough road. In this paper. a linear vehicle model was built for power spectral density analysis and validated with test below 20Hz. To select out design variables which are effective to reduce acceleration level within a certain frequency range. dynamic response sensitivy analysis was carried out. After that. the effect of changes of those design variables was reviewed in power spectral density analysis.<br/>
Shared Memory Model over a Switchless PCIe NTB Interconnect Network
임승호,차광호 한국정보처리학회 2022 Journal of information processing systems Vol.18 No.1
The role of the interconnect network, which connects computing nodes to each other, is important in highperformancecomputing (HPC) systems. In recent years, the peripheral component interconnect express (PCIe)has become a promising interface as an interconnection network for high-performance and cost-effective HPCsystems having the features of non-transparent bridge (NTB) technologies. OpenSHMEM is a programmingmodel for distributed shared memory that supports a partitioned global address space (PGAS). Currently, littlework has been done to develop the OpenSHMEM library for PCIe-interconnected HPC systems. This paperintroduces a prototype implementation of the OpenSHMEM library through a switchless interconnect networkusing PCIe NTB to provide a PGAS programming model. In particular, multi-interrupt, multi-thread-based datatransfer over the OpenSHMEM shared memory model is applied at the implementation level to reduce thelatency and increase the throughput of the switchless ring network system. The implemented OpenSHMEMprogramming model over the PCIe NTB switchless interconnection network provides a feasible, cost-effectiveHPC system with a PGAS programming model.
