results the results showed that the epoxy plates 6 and 2 mm thick had the highest and the lowest averages of shielding effectiveness at 4.48 db and 1.90 db, respectively. however, increasing the thickness was useful up to 4 mm. in addition, in a similar attenuation pattern, x-band frequency was divided into lower, middle, and upper sections. the lower section had the highest shielding effective...

Modern technology makes garments smart, which can help a wearer to manage in specific situations by improving the functionality of the garments. The personal heating garment (PHG) widens the operating temperature range of the garment and improves its protection against the cold. This paper describes several kinds of PHGs worldwide; their advantages and disadvantages are also addressed. Some cha...

A considerable amount of research into garments for protecting man against hot and cold conditions has been reported. Some of the earliest work was reported in the late 1950's and early 1960's, on garments used for maintaining thermoneutrality in pilots who endured high temperatures due to the sunlit aircraft cockpit. This work was performed at the Royal Aircraft Establishment. Further research...

The presence of characteristic fine folds is important for modeling realistic looking virtual garments. While recent garment capture techniques are quite successful at capturing the low-frequency garment shape and motion over time, they often fail to capture the numerous high-frequency folds, reducing the realism of the reconstructed spacetime models. In our work we propose a method for reintro...

In November 1997, Experiment T423 began acquiring data with the intentions of understanding the energy spectra of high-energy neutrons generated in the interaction of electrons with lead. The following describes a series of FLUKA simulations studying (1) particle yields in the absence of all background; (2) the background caused from scattering in the room; (3) the effects of the thick lead shi...

for superficial lesions, the electrons may be used for radiation therapy. the high energy photons and electrons are produced by a linear accelerator (linac).   many of electron fields need the shielding of normal or critical organs. the electron shields are usually lead slabs with few millimeter thickness which should be placed near the skin, less than 1 centimeter away from skin. in the inspec...

Against the detrimental effects of ionizing radiation, time, distance, and shielding are three most significant protective methods. Lead is material choice for shielding, particularly personal equipment. However, lead's density, rigidity, toxicity disadvantages. In recent years, tungsten-containing rubber (TCR) other lightweight, flexible, non-toxic materials have emerged as viable alternatives...

Modeling of three-dimensional garments is essential for creating realistic virtual environments and is very helpful for real-life garment design. While fashion drawings are commonly used to convey garment shape, so far little work had been done on using them as inputs to the 3D modeling process. We present a new approach for modeling of garments from fashion drawings. This approach combines an ...
