This paper describes voxel-based hand posture estimation using the Expectation Constrained-Maximization framework to estimate the parameters to a 16 segment 24 degreesof-freedom hand model. This method uses only voxels to estimate finger segment locations and orientations. The hand model consists of a mixture of kinematically constrained 3D gaussian distributions. Results on simulated and real ...

Prototypes for automated spatial layout in architecture focus on approaches, which define occupiable space as an orthogonal 2D-grid and use algorithms to allocate each rectangle of the grid to a particular function. However, these approaches are limiting the design to orthogonal spatial layouts. Based on SAT solving techniques, the prototype presented in this paper proposes a methodology for au...

Voxelization is the transformation of geometric surfaces into voxels. Up to date this process has been done, essentially using incremental algorithms. Incremental algorithms have the reputation of being very eÆcient but they lack an important property: robustness. The voxelized representation should envelop its continuous model. However, without robust methods this cannot be guaranteed. This te...

background: the heterogeneous composition of the human body presents numerous tissue types and cavities with widely differing radiologic properties. the aim of the present work was to develop a low cost homogeneous and heterogeneous phantom and the absorbed dose were measured by ionization chamber for different radiotherapy treatment techniques and compared with treatment planning system absorb...

background long-term clinical symptoms and functional status of above-knee amputees are not well documented. this study documents the long-term outcomes of war related above-knee amputations. objective to study the long-term outcomes of unilateral above-knee amputation. materials and methods the study consisted of a comprehensive assessment, examination, and review of history and wartime medica...

introduction based on task group no. 43 (tg-43u1) recommendations, water phantom is proposed as a reference phantom for the dosimetry of brachytherapy sources. the experimental determination of tg-43 parameters is usually performed in water-equivalent solid phantoms. the purpose of this study was to determine the conversion factors for equalizing solid phantoms to water. materials and methods t...
