In this paper a novel algorithm for lossless compression of volumetric data is presented. This algorithm is based on our previously presented algorithm for lossless compression of volumetric data, which uses quadtree encoding of slices of data for discovering the coherence and similarities between consecutive slices. By exploiting these properties of the data, the algorithm can efficiently comp...

In this paper we present a humidity sensor based on keratin which is present in human hair. Noting keratin’s ability to absorb humidity and undergo structural changes, we studied the change in its electrical properties as a function of humidity and temperature. The electrical properties change due to the change in water percentage in keratin as well as due to volumetric changes. The volumetric ...

With the dramatic increase of 3D imaging techniques, there is a great demand for new approaches in texture analysis of volumetric data. In this paper, we present a new approach for volumetric texture analysis using a runlength encoding matrix and its texture descriptors. We experiment with our approach on the volumetric data generated from two normal Computed Tomography (CT) studies of the ches...

the physicochemical properties of solute in solutions provide valuable information on solute –solvent, solute – solute and solvent – solvent interactions. the intermolecular forces between theliquids molecules and solvent molecules affect the viscosity of the solution. information regardinginter and intra molecular interactions can be obtained from volumetric, and viscometric data in asolute so...

The objective in this case is not only to be realistic, but also to provide new and intelligible ways of model representation. This raises new issues in data perception. The question of perception of complex data, especially regarding visual feedback, is an open question, and it is the subject of this work. This PhD thesis studied the human perception in Immersive Virtual Environments of comple...

The study was conducted to test the effect of dexamethasone introduced intramuscularly on volumetric mineral density and physical properties of the femur and humerus in piglets during 14 d of their neonatal life. The effective duration of dexamethasone action lasted together 38 d because sows were treated with dexamethasone during the last 24 d before farrowing. Control piglets were treated wit...

The energetic and volumetric properties of a three-state protein folding system, comprising a metastable triple mutant of the Fyn SH3 domain, have been investigated using pressure-dependent (15) N-relaxation dispersion NMR from 1 to 2500 bar. Changes in partial molar volumes (ΔV) and isothermal compressibilities (ΔκT ) between all the states along the folding pathway have been determined to rea...
