In a randomized clinical trial, 90 concerned significant others (CSOs) of treatment-refusing illicit drug users were assigned to either (a) community reinforcement and family training (CRAFT), which teaches behavior change skills: (b) CRAFT with additional group aftercare sessions after the completion of the individual sessions: or (c) AI-Anon and Nar-Anon facilitation therapy (AI-Nar FT). All ...

An Electric Solar Wind Sail (E-sail) is a propellantless propulsion concept that extracts momentum from the high-speed solar wind stream to generate thrust. This paper investigates performance of such system in obtaining transition prograde retrograde motion. The spacecraft assumed initially trace circular heliocentric orbit given radius. particular trajectory, referred as Circular Orbit Flip T...

The Stanford hand-eye system is implemented as several separate tasks, each executing under a timesharing executive. Development of a programming language (SAIL) and augmentation of the timesharing system were required to provide the necessary data sharing and control flow among the tasks. The SAIL language provides fac i l i t i es for "associative processing," and is extended to serve the dat...

The paper presents a weather routing solution for sail-assisted ships. Since the route finding optimisation process is a multiobjective one, the emphasis is put on possible application of multiobjective optimisation methods. The paper focuses on two such methods, namely evolutionary algorithms and ranking methods represented by Fuzzy TOPSIS. In addition, a proposed set of optimization criteria ...

MetalJunction.com is a joint venture of TISCO and SAIL, the steel makers contributing more than 60% to India’s total steel production. The case illustrates how organization(s) can use information technology to spin off key processes such as procurement and selling. In its first year of operations MetalJunction.com generated substantial savings for TISCO and SAIL. The case also supports the argu...
