This paper discusses an interface power converter between a power grid and an engine generator. A matrix converter, which is one of the AC/AC direct converters, can achieve high efficiency without large energy storages. Therefore, the volume of the converter becomes smaller and the reliability of the interface system is improved due to no use of electrolytic capacitor. This paper discusses the control...
In this paper, we propose a new criterion for the extrinsic information transfer (EXIT) analysis in the spectrum-overlapped resource management (SORM) for a broadband single carrier transmission. In the SORM technique, each user can ideally obtain a maximum channel gain by allowing overlapped allocation, assuming the soft canceller with minimum mean square error (SC/MMSE) turbo equalization for multi-user...
We have theoretically investigated electronic properties of InAs/GaAs quantum-dot superlattices in which a potential well is inserted in the center of each InAs quantum dot. We find that the potential well pulls down exclusively the energy of the lowest miniband and provides an additional design parameter for solar cell application.
This paper investigates solutions to improvement of realistic rendering quality of CG (Computer Graphics) character face. In order to manipulate face skin feature distribution, based on bio-anatomic structure, skin surface is classified into 3 layers (Internal, Regular and Local layer) to control skin base color, surface cellular venation level and noise distribution like freckle, respectively. Moreover,...
This paper presents a method for prediction of protein functions based on protein-protein interaction (PPI) networks. It can be hypothesized that unknown function proteins that form a densely connected subgraph with proteins of a particular function are likely to belong to the same functional group. The proposed approach utilizes this concept by determining k-cores of strategically constructed subnetworks...
