This paper discusses the approach being taken by XPRS, a software data base machine being built at Berkeley, tow ard intra-query parallelism. There are two components to our design. The first is a unique two-dimensional file system called FTD which automatically balances arm activity among multiple disks. The second component is the novel way that we construct parallel plans by making use of in...

Contiguous graphite fins can be grown with Microwave Plasma CVD from the surface of different types of thermally conductive (TC), graphite fibers. The fins grow from all fiber filaments in multiple same TC graphite fiber tow bundles. Fin morphology consists of contiguous branching graphene basal planes originating from the fiber’s surface and curling outwards regardless of the fiber’s isotropic...

Recent developments in both optical wireless communication (OWC) systems and implanted medical devices (IMDs) have introduced transdermal (TOW) technology as a viable candidate for extremely high-speed in-body to out-of-body data transmissions, which are growing demand many vital biomedical applications, including telemetry with implants, health monitoring, neural recording prostheses. Neverthe...

Benefiting from curved fibre paths, variable-angle-tow (VAT) composites feature a larger design space than traditional straight-fibre reinforced plastics. Herein, an optimisation framework of full-scale wing-box structure with VAT-fibre is presented, aiming at minimised mass and optimised local buckling performance under realistic aeroelastic loading conditions. Local analyses on individual sub...

The realization of the Tow–Thomas (TT) circuit using the Operational Transresistance Amplifier (OTRA) is reviewed. The circuit employs two OTRA, and all passive elements are floating as the original Tow–Thomas circuit. The Current Conveyor (CCII) TT circuits are reviewed next. The progress in the realization of the TT circuit using CCII is demonstrated clearly by summarizing eight different cir...

The main focus of this study has been on the development of a conceptual framework for improving the current status of industrial accidents’ control. The framework is aimed to use of ICT to improve the information exchange between the Civil Defence and Industrial Sector and to provide an information management system model for the Industrial Incidents Administration System (IIAS). The purposed ...

In this article we are going to compare useful cryptology algorithm in different area and explain them though application of algorithms have very large but doing some comparison one can do decision usage introduced right place. first mention important point of, digital signature distribution key then these tow algorithms.
