While genetically inspired approaches to multi-objective optimization have many advantages over conventional approaches, they do not explicitly exploit directional/gradient information. This paper describes how steepestdescent, multi-objective optimization theory can be combined with EC concepts to produce improved algorithms. It shows how approximate directional information can be efficiently ...

We construct quantum deformation of Poincaré group using as a starting point SU(2, 2) conformal group and twistor-like definition of the Minkowski space. We obtain quantum deformation of SU(2, 2) as a real form of multi-parametric GL(4, C) q ij ,r. It is shown that Poincaré subgroup exists for special nonstandard one-parametric deformation only, the deformation parameter r being equal to unity....

A novel test configuration has been developed to induce combined stress-states of in-plane longitudinal tension and transverse compression in thin-ply, unidirectional (UD) composite layers. Three different multi-directional laminates have designed incorporating UD carbon/epoxy plies embedded angle-ply blocks the same material. The scissoring deformation induces central layers when is strained 0...

The spaceborne ESA-mission CHRIS-Proba (Compact High Resolution Imaging SpectrometerProject for On-Board Autonomy) provides hyperspectral and multi-directional data of selected targets spread over the world. While the spectral information content of CHRIS/Proba data is able to assess the biochemistry of a vegetation canopy, the directional information can describe the structure of an observed c...

A high-speed memory bus interface which enables greater throughput for data reads and writes is described in this paper. Current mode CMOS logic synthesis methods are used to implement multi-valued logic (MVL) functions to create a high bandwidth bus. First, a fundamental bi-directional data bus for multiple logic levels is presented. Then a bi-directional data bus with impedance matching termi...

Strength, stiffness, strain at fracture and moisture content of onion skins were measured after incubation at a range of humidities. Higher relative humidity (RH) resulted in skins which had greater moisture content, were stronger in multi-directional tests and which were less stiff. In uni-directional tests, skins incubated at higher RH had extended more at fracture than those incubated at low...

This paper proposes a novel method for estimating depth from long-baseline image sequences captured by a precalibrated moving omni-directional multi-camera system (OMS). Our idea for estimating an omni-directional depth map is very simple; only counting interest points in images is integrated with the framework of conventional multibaseline stereo. Even by a simple algorithm, depth can be deter...
