In this paper, a new approach named focal region-based volume rendering for visualizing internal structures of volumetric data is presented. This approach presents volumetric information through integrating context information as the structure analysis of the data set with a lens-like focal region rendering to show more detailed information. This feature-based approach contains three main compo...

This paper presents the results of a formal experiment to compare different interaction techniques across two types of immersive display: an immersive projection technology (IPT) and a headmounted display (HMD). Our aim is to investigate the effectiveness of two widely used interaction metaphors, virtual hand and ray casting on these two display technologies. Our motivation is that design and e...

In anatomical illustrations deformation is often used to increase expressivity, to improve spatial comprehension and to enable an unobstructed view onto otherwise occluded structures. Based on our analysis and classification of deformations frequently found in anatomical textbooks we introduce a technique for interactively creating such deformations of volumetric data acquired with medical scan...

UNLABELLED A simple, low-cost, versatile, and potentially scalable casting method is proposed for the fabrication of micro- and nano-thin films, herein termed as ultrasonic "substrate vibration-assisted drop casting" (SVADC). The impingement of a solution drop onto a substrate in a simple process called drop casting, usually results in spreading of the liquid solution and the formation of a non...

Φ-value analysis has proved to be a powerful technique in protein folding studies. It has been used to study the transition state structures, to infer microscopic folding pathways, and to identify key residues in the protein folding process. However, its effectiveness in protein binding reaction has not been tested, especially when a fly-casting mechanism is involved. In this article we attempt...

The Selective Laser Sintering Process of thermoplastics (SLS) enables the manufacturing of components with complex shape in a short time period without the manufacturing of a specific mold. However, this manufacturing process is limited by the restricted range of materials. In contrast to this primary shaping process, vacuum casting allows a quick, inexpensive and highly accurate process but it...

introduction: plastination is a unique technique for preservation of biological specimens used for teaching purposes. the protocol of flexible sheet plastination includes fixation, slicing, dehydration, force impregnation, casting, and curing (hajian, rabiei, fatollahpour & esfandiary, 2008). the procedure is done by using p87 flexible unsaturated polyester resin and provides heavy, gross, frag...

The field of Mobile Adhoc Network (MANET) has become very popular because of the deep research done in that area in last few years. MANET has advantage of operating without fixed infrastructure and also it can tolerate many changes in the network topology. The MANET uses different routing protocols for End to End Packet delivery. This paper is subjected to the Reactive routing protocols on the ...

The purpose of this study is to synthesize nano-grained Calcium Hydroxyapatite (HAp) through slip casting technique. For this, hydroxyapatite powders were synthesized using two methods, wet chemical method and Ammoniacal method. The as-prepared powders and calcined powders were characterized using XRD, FTIR, to study the phases of the powders. The hydroxyapatite powder calcined at 1000°C for 2h...
