A distributed E-Business System based on conic curve is proposed. This scheme is composed of two parts, constructing license and validating license. Because the security of license is determined by private key, not the arithmetic itself, user can not construct new license by given license and the public key as long as the private key is not leaked. Since encoding and decoding over conic are eas...

The Conic Benchmark Library (CBLIB 2014) is a collection of more than a hundred conic optimization instances under a free and open license policy. It is the first extensive benchmark library for the advancing field of conic mixed-integer and continuous optimization, which is already supported by all major commercial solvers and spans a wide range of industrial applications. The library addresse...

This paper considers supply chain design in green logistics. We formulate the choice of an environmentally conscious chain design as a multi-objective optimization (MOO) problem and approximate the Pareto front using the weighted sum and epsilon constraint scalarization methods as well as with two popular genetic algorithms, NSGA-II and SPEA2. We extend an existing case study of green supply ch...

People know and use conic sections for a long time. They observe these curves in many situations: the parabolic trajectory of a thrown stone, the circular waves when the stone falls in calm water, and the elliptical shadows of round objects during sunsets (see Fig. 1). Conic sections were and still are one of the most favorite objects of mathematical study and education. Students spend hours in...

Paracatadioptric sensors combine a parabolic shaped mirror and a camera inducing an orthographic projection. Such a configuration provides a wide field of view while keeping a single effective viewpoint. Previous work in central catadioptric sensors proved that a line projects into a conic curve and that three line images are enough to calibrate the system. However the estimation of the conic c...

The underlying model of distributed systems is that of loosely coupled components r running in parallel and communicating by message passing. Description, construction and evolution of these systems is facilitated by separating the system structure, as a set of components and their interconnections, from the functional description of individual component behaviour. Furthermore, component reuse ...
