This paper is aimed at analyzing the performance of three different state-of-the-art image compression schemes namely Embedded Zerotree Wavelet (EZW), Spatial-orientation Trees Wavelet (STW) and Set Partitioning in Hierarchical Trees (SPHIT). The paper analyses the compression schemes using X-ray image data such that the quality of the reconstructed image would be closely related to its origina...

There is a richly documented fossil record of the evolutionary transition from ape-sized brains that are less that one-third the size of modern humans through a series of intermediate-sized brains up to the modern range. The first report on the discovery of the foot of the Stw 573 skeleton emphasized the apparent transitional nature of its great toe [Clarke, R.J., Tobias, P.V., 1995. Sterkfonte...

The objective of this paper is to implement and evaluate the effectiveness of wavelet based Spatial-orientated Tree Wavelet (STW), 3D-Set Partitioning in hierarchical trees (3D-SPIHT) and Adaptively Scanned Wavelet Difference Reduction (ASWDR) compression techniques using MATLAB R2010b. The performance parameters such as Peak Signal to Noise Ratio (PSNR), Mean Squared Error (MSE), Compression R...

Dydra is an RDF graph storage service. It stores and retrieves the contents of RDF datasets through SPARQL, LDF and LDP interfaces. In addition to these basic capabilities, it retains previous store states, in addition to the current state, as active addressable aspects of a dataset analogous to named graphs in a quad store. It incorporates arbitrary revisions into target datasets according to ...

The shape of the distal humerus in Homo, Pan (P. paniscus and P. troglodytes), Gorilla, and six australopithecines is compared using a geometric approach (Procrustes superimposition of landmarks). Fourteen landmarks are defined on the humerus in a two-dimensional space. Principal components analysis (PCA) is performed on all superimposed coordinates. I have chosen to discuss the precise place o...

Tissue engineering is a clinical approach toward the development of dynamic molecular delivery that can restore and improve regeneration. The 3D models and regenerative principles applied during implant guided dental surgery open new approaches for tissue constructs favoring sinus lift and implant placement. Purpose: The aim of the present clinical study was to determine evidence that synergy b...
