A miniaturized strain gauge with a thickness of 5 µm is molded into a silicone O-ring. This is a first step toward embedding sensors in gaskets for structural health monitoring. The signal of the integrated sensor exhibits a linear correlation with the contact pressure of the O-ring. This affords the opportunity to monitor the gasket condition during installation. Thus, damages caused by faulty...

The Sierpinski triangle also known as Sierpinski gasket is one of the most interesting and the simplest fractal shapes in existence. There are many different and easy ways to generate a Sierpinski triangle. In this paper we have presented a new algorithm for generating the sierpinski gasket using complex variables.

Introduction: Adequate reconstruction of the skull base is the key to avoiding cerebrospinal fluid (CSF) leak following endonasal skull base surgery. The use of an endocranial “gasket” plug has been reported for this and is used in our institution. We present a simple refinement of the “gasket” technique using commonly available materials that helps ensure proper size and positioning of the gas...

Recent advances in high-pressure diamond anvil cell experiments include high-energy synchrotron x-ray techniques as well as new cell designs and gasketing procedures. The success of high-pressure experiments usually depends on a well-prepared sample, in which the gasket plays an important role. Various gasket materials such as diamond, beryllium, rhenium, and stainless steel have been used. Her...

Combined plastic flow and strain-induced phase transformations (PTs) under high pressure in a sample within a gasket subjected to three dimensional compression and torsion in a rotational diamond anvil cell (RDAC) are studied using a finite element approach. The results are obtained for the weaker, equal-strength, and stronger high-pressure phases in comparison with low-pressure phases. It is f...

This article examines the reduction of speedand heat loss in passenger compartment an electric vehicle (EV) when installing additional thermal insulation gasket on doors. The study was conducted conditions extremely low outdoor temperatures that occur winter season northern and arctic regions. To conduct a series observations, doors car were equipped with (second) heat-insulating rubber gasket....

The use of a polymeric Torlon (polyamide-imide) gasket material in a Paris-Edinburgh pressure cell for in situ high-pressure X-ray scattering measurements is demonstrated. The relatively low bulk modulus of the gasket allows for fine control of the sample pressure over the range 0.01-0.42 GPa. The quality of the data obtained in this way is suitable for Bragg and pair distribution function anal...

We study not necessarily self-similar Dirichlet forms on the Sierpiński gasket that can be described as limits of compatible resistance networks on the sequence of graphs approximating the gasket. We describe the compatibility conditions in detail, and we also present an alternative description, based on just 3 conductance values and the 3-dimensional space of harmonic functions. In addition, w...
