Deep Neural Networks are often though to lack interpretability due to the distributed nature of their internal representations. In contrast, humans can generally justify, in natural language, for their answer to a visual question with simple common sense reasoning. However, human introspection abilities have their own…
Horizontal copper plating processes have been used in high volume production to produce PCB's for MLB, Flex-rigid, IC substrates and HDI applications. As the lines and spaces (L/S) requirements have become more and more challenging over the years, panel plating technology has hit the barrier in the range of L/S 35/35…
Due to the EU rules on mercury, the UV lamp will be disallowed to include mercury in 2020. Therefore, the UV LED becomes the alternative solution instead of UV lamp. However, based on the limitation of photoelectric efficiency in UV LED, most electricity will be dissipated and generate heat. Thus, the great thermal di…
Simulating the steam Injection process of pressurized decompression tanks is a challenging engineering problem due to the large amount of computational resource requirements and its complex physical model. This study is a necessary algorithmic study to perform a 3D numerical simulation from the PRT (Pressurizer Relief…
Cryo-electron microscopy(cryo-EM) has been widely used in structural biology. Molecular particle selection in cryo-EM micrographs as an important intermediate affects the quality of 3D reconstruction. A new method called RSelector is proposed with a new feature extraction network based on characteristics of cryo-EM mi…
Effect of surfactants on electrical conductivity of an epoxy-based electrically conductive adhesive (ECA) was examined. 1,2,3-triazole, 1,2,3-benzotriazole surfactants were found to effectively accelerate electrical conductivity development during curing of the adhesives. By contrast, electrical conductivity developme…

Template-free CuO nanorods were synthesized through a three-step chemical method with no water-insoluble materials. The first step included the preparation of a Cu-complex, which was obtained from dipicolinic acid, L-lysine, and copper nitrate. Then, as the second step, the obtained solution was allowed to be relaxed…
Doping high thermal conductivity fillers into polymers as a major way to improve the thermal conductivity of materials, but the failure mechanism of the coupling agents and entangled polymer chains on the thermal conductivity of nanofillers is missing. In order to explore those, the thermal conductivity of pure BN nan…
Insulators of the spacer have been studied to relax the electric field in order to downsize gas insulated switchgears (GISs). We have been researching to make electric field relaxation of solid insulation material by filling with ZnO varistor granules. In our previous study, when we applied positive lightning impulse…
Indoor electrical devices like smoothing reactor in Ultra High Voltage Direct Current (UHVDC) converter station demand certain performance in discharge characteristic, which is of vital importance in the valve hall and indoor Direct Current (DC) field. Concerning the complexity of structure in the valve hall and DC fi…
The Partial Discharge phenomenon represents one of the major causes of the deterioration and ageing of the insulating systems of electric machines and, consequently, leads to a considerable shortening of their lifetime. Although the theory and practice focus more on partial discharges caused by a sinusoidal power supp…
Nickel oxide (NiO) nanoparticles were produced by wire explosion process (WEP) in Oxygen ambience. XRD studies have confirmed the formation of NiO during WEP under oxygen rich environment and with high energy ratios. Crystallite size of synthesized NiO nanoparticles was found to be 26.7 nm. The particles produced are…
Energetic electrons from the space can penetrate through the aluminum shield of spacecraft and deposit in the deep layer of insulating materials, leading to internal charging. When the space charge accumulation exceeds a certain threshold, Electric field distortion occurs, resulting in the failure of electronic equipm…

In our previous studies, we confirmed that the breakdown voltage did not decrease significantly even if nitrogen (N2) fine bubbles were added to pure water. In addition, we confirmed that the conductivity of pure water increased when we used a metallic fine bubble generator. In this study, we investigated an influence…
Nano-coatings, which are generally composed of inorganic nanofillers and polymer binders, have attracted increasing interest in electrical industry, because of their unique advantages for improving the dielectric and electrical properties of the electric devices, accompanied by the versatile manufacturing process. Her…
In experiment, it was found that the electrons injected into fluorinated polyethylene (PE) were much less than pure PE. In order to clarify the microscopic mechanism of this phenomenon, the PE/fluorinated layer structure is constructed with the help of molecular dynamics. The constructed model's density is in correspo…
The contact form between the electrode and the insulator is an important factor affecting flashover. In this paper, the surface flashover characteristics of insulators in three different contact forms were studied in C4F7N/CO2mixtures, which is a new environmental-friendly gas. And through the calculation and analysis…
Hydrophobicity and flashover strength are important properties of outdoor insulators, especially in the tropic region, which have high pollution and high intensity of rainfall. This study examines the impact coal fly ash as a micro filler on static hydrophobicity and DC dry flashover strength of the silicon rubber. Th…
