Long-lived, dependable systems evolve during their life time: new functionality is added, errors are discovered, new requirements appear, etc. It is often infeasible to stop and redeploy a system in order to upgrade it, due to the associated downtime. A system that can adapt to changes dynamically is more dependable. In this paper we present dynamic ABS: to cope with the need to modify ABS code...

The ABS control problem is described, with a discussion on relevant hybrid control aspects. Next, we comment on conventional ABS design methods and present some new ideas and results on model-based ABS control design that relies on elements of hybrid control.

We present the main results obtained during a research on ABS methods in the framework of the project Analisi Numerica e Matematica Computazionale. 1. – The ABS algorithms. ABS algorithms were introduced by Abaffy, Broyden and Spedicato (1984), to solve linear equations first in the form of the basic ABS class, later generalized as the scaled ABS class and applied to linear least squares, nonli...

This study set out to evaluate the effectiveness of antilock brake system (ABS) technology on motorcycles in reducing real-life injury crashes and to mitigate injury severity. The study comprised an analysis of in-depth fatal crash data in Sweden during 2005-2008 to investigate the potential of ABS as well an estimate of the effectiveness of ABS in crash reduction in Sweden between 2003 and 200...

OBJECTIVES We sought to test the hypothesis that autoantibodies (Abs) produced against sarcolemmal Na-K-ATPase play a role in the development of ventricular tachycardia (VT) and cardiac sudden death in patients with dilated cardiomyopathy (DCM). BACKGROUND Autoimmunity is one of the mechanisms of pathogenesis of DCM as well as virus infection and genetic predisposition. METHODS One hundred ...

This paper gives a survey of the theory and practice of nonlinear ABS methods including various types of generalizations and computer testing. We also show three applications to special problems, two of which are new.

Attribute based signature schemes (ABS) constitute important and powerful primitives when it comes to protecting the privacy of the user’s identity and signing information. More specifically, ABS schemes provide the advantage of anonymously signing a message once a given policy is satisfied. As opposed to other related privacy preserving signatures, the verifier is not able to deduce from the s...

Abscondita, a new genus of fireflies from South-east Asia, is described from males and females of Abs. anceyi (Olivier 1883), Abs. cerata (Olivier 1911), Abs. chinensis (L. 1767), Abs. perplexa (Walker 1858), Abs. promelaena (Walker 1858) and Abs. terminalis (Olivier 1883), all transferred from Luciola Laporte. Both L. dubia Olivier 1903 and L. dejeani Gemminger 1870 are synonymised with Luciol...

A new hybrid fabrication technique was introduced to manufacture composite laminates made of glass fiber, carbon and acrylonitrile butadiene styrene (ABS) as the matrix. The process utilized two different techniques: fused deposition modeling hot press molding. were produced using five layers fibers form fiber-reinforced composites (GF/ABS) fiber (GF/CF/ABS), with three fibers. fabricated subje...
