Two inbred strains of Tsukuba Emotionality Rat (THE and TLE) and four hybrids derived from them were observed for ambulatory response in a novel environment as a measure of emotionality. The Runway Test (modified "timidity test") was run for successive three days. Mean transformed (square root) scores of ambulation for generation were subjected to Mendelian cross analysis. Total ambulation scor...

We show that for a measure -y on a Banach space directional different ¡ability implies quasi-translation invariance. This result is shown to imply the Cameron-Martin theorem. A second application is given in which 7 is the image of a Gaussian measure under a suitably regular map.

We introduce an isotropic measure of local contrast for natural images that is based on analytic filters and present the design of directional wavelet frames suitable for its computation. We show how this contrast measure can be used within a masking model to facilitate the insertion of a watermark in an image while minimizing visual distortion.

This paper uses theory, simulation, and laboratory experiment, to show that directional illumination, used during the image acquisition process, acts as a directional filter of three dimensional texture. It is shown that the directional characteristics of image texture are not intrinsic to the physical texture being imaged, as they are affected by the direction of the illumination. This result ...

Nonlinear interdependencemeasures can be used to detect directional couplings between stationary dynamical systems from a pair of signals measured from them. For many dynamics, however, intermittent directional couplings arise in causal relation to distinct events on timescales that are often too short to be resolved by nonlinear interdependence measures. On the other hand, in many experimental...

A new measure of directional linkage disequilibrium is developed for detecting epistatic selection on interacting genes. Simulations show that by orienting the direction of linkage disequilibrium on the basis of the ancestral-derived status of alleles, the new measure indeed improves the power to detect a positive fitness interaction between two new mutations.

Decorrelate-and-forward relaying scheme for wireless synchronous code division multiple access (CDMA) networks where multiple sources communicate with a destination supported by multiple relays in flat Rayleigh fading channels is considered. By exploiting equicorrelated spreading sequences, a simple near–far resistant decorrelator together with a beamforming scheme at each relay and the maximal...

The non-differentiability and implicit definition of boundary of production possibility set (PPS) in data envelopment analysis (DEA) are two important difficulties for obtaining directional characteristics, including different elasticity measures and marginal rates of substitution. Also, imposing weight restrictions in DEA models have some shortcomings and misunderstandings. In this paper we ut...

We describe a method for visual based robot navigation with a single omni-directional (catadioptric) camera. We show how omni-directional images can be used to generate the representations needed for two main navigation modalities: Topological Navigation and Visual Path Following. Topological Navigation relies on the robot’s qualitative global position, estimated from a set of omni-directional ...
