Thermal Diffusivities of Composites with Various Types of Filler

Abstract: In-plane and out-of-plane thermal diffusivities (conductivities) of Kerimid resin composites reinforced with various types of filler were studied both experimentally and theoretically. The types of...

System and method for locating and installing device drivers for peripheral devices

Abstract: A destination computer reads a device identification and a network address from a peripheral device connected to the destination computer. A device driver, corresponding to the device identification, is then retrieved from the source computer at the network address. A device driver installation program can also be retrieved from the source computer. The device driver installation program is executed in the destination computer to determine the configuration of the destination computer. The destination computer requests the device driver for the peripheral device corresponding to the configuration of the destination computer from the source computer. The device driver is installed in the destination computer.

A Home Automation System

Abstract: A Home Automation (HA) System based on the Home Bus system has been developed. The system has a multi-layered hierachical structure and is composed of four subsystems (the Room Monitor Control Subsystem, the Telephone Subsystem, the Tele-control Subsystem and the In-house Video Control Subsystem). The HA system has both three inner-subsystem communication codes and one inter-subsystem communication code. The former are optimized for each subsystem and the latter enables the HA system to have efficiently combined applications. A compact (48.6 x 31 x 4 mm) communication control module which interfaces household appliances with the Home Bus has also been developed as one of the key parts for the system.

Security proof for quantum-key-distribution systems with threshold detectors

Abstract: In this paper, we rigorously prove the intuition that in security proofs for the Bennett-Brassard 1984 (BB84) protocol, one may regard an incoming signal to Bob as a qubit state. From this result, it follows that all security proofs for BB84 protocol based on a virtual qubit entanglement distillation protocol, which was originally proposed by Lo and Chau [Science 283, 2050 (1999)] and by Shor and Preskill [Phys. Rev. Lett. 85, 441 (2000)], are all valid even if Bob's actual apparatus cannot distill a qubit state explicitly. As a consequence, especially, the well-known result that a higher bit error rate of 20% can be tolerated for BB84 protocol by using two-way classical communications is still valid even when Bob uses threshold detectors. Using the same technique, we also prove the security of Bennett-Brassard-Mermin 1992 (BBM92) protocol where Alice and Bob both use threshold detectors.

Grain size effect of electro-plated tin coatings on whisker growth

Abstract: Tin and tin-lead coatings electro-plated in various solutions have been observed by means of high voltage electron microscopy, and the grain size effect of the coatings on whisker growth has been examined As a result, it was found that the tin and tin-lead coatings from which whiskers hardly grew consisted of well-polygonized grains which were a few micrometre in size, and that the tin coatings from which whiskers easily grew consisted of irregular-shaped grains which were a few tenths of a micrometre in size The irregularshaped grains contained dislocation rings which might be formed by clustering of vacancies or interstitial atoms upon electro-plating
