As a distributed process calculus with localities and mobility of computational entities, Seal calculus is playing an important role in expressing key features such as security and mobility of Internet programming directly. However, little implementation technique proposed for the calculus, partly due to the complication of mobile computation, which fusions three important techniques: concurren...

This study was conducted to clarify the degree to which a master cast needs to be carved to obtain a posterior palatal seal according to Swenson, based on a comparison among four dental practitioners. Sections of the casts with the seal scraped were made, and an optical microscope was used to measure the sagittal and vertical dimensions. It was found that the sagittal dimension may show a small...

The most important problem on seal imprint verification is to extract the imprint feature, which is independent upon varying conditions. This paper proposes a new method to extract the feature of seal imprint using the doubledensity dual-tree DWT due to its good directional selectivity, approximate shift invariance and computational efficiency properties. 16 different directions information is ...

the seleucid seals and bullae play a significant role in understanding the administration and social structures of this period. due to the limitations in the seleucids sigillographic study, a wide variety of administrative archives of bullae found from important sites such as qumis, susa, babylon, nippur and kadesh are waiting for the researchers to deal with the bullae’s various aspects. apart...

The Angio-Seal vascular closure device has been shown to be safe and effective in decreasing the time to hemostasis after percutaneous coronary intervention (PCI). The health economic implications of routinely using Angio-Seal after PCI have not been explored. We performed a cost-minimization analysis comparing routine Angio-Seal use after PCI with mechanical compression using a decision analyt...

Mechanical seals are the most common means of sealing industrial centrifugal pumps. There are a wide variety of seal options including the use of single or dual seal arrangements. While dual seals provide benefits in leakage containment and monitoring, single seals continue to be widely used due to their lower cost and simpler designs. Newer piping plans however offer options to increase leakag...

The motion of isolated seal vibrissae due to low frequency sound in air has been measured using a microscope with a video camera and modeled using an FEM method with good agreement between the measurements and the model; the model has also been used to predict the motion of seal vibrissae in water. The shape of the seal vibrissae is that of a tapered right rectangular prism, unlike that of the ...
