This study investigated the feasibility of the micro powder blasting technique for the micro fabrication of sensor structures using the Pyrex glass to replace the existing silicon-based acceleration sensor fabrication processes. As the preliminary experiments, the effects of the blasting pressure, the mass flow rate of abrasive and the number of nozzle scanning times on erosion depth of the Pyr...

Exotic semiring constraints arise in a variety of applications and in particular in the context of automated termination analysis. We propose two techniques to solve such constraints: (a) to model them using Boolean functions and integer linear arithmetic and solve them using an SMT solver (QF LIA, in certain cases also QF IDL); and (b) to seek finite domain solutions by applying unary bit-blas...

Received: March 17, 2017 Revised: July 25, 2017 Accepted: August 18, 2017 Abstract: Introduction: For technical renovation of the thermal plant, one frame structure workshop of 50,000 m construction area and one reinforcement concrete chimney of 150m height shall be demolished by blasting in the same time. The engineering environment is very complicated and the accommodation space for the struc...

Traditionally, transfer functions have been manually designed for each operation in a program. Recently, however, there has been growing interest in computing transfer functions, motivated by the desire to reason about sequences of operations that constitute basic blocks. This paper focuses on deriving transfer functions for intervals — possibly the most widely used numeric domain — and shows h...

We report the case of a young patient who underwent renewed aortic valve replacement, after open blasting of the aortic valve and subsequent valve replacement with enlargement of the ascending thoracic aorta using an autologous pericardium patch had already taken place. In the context of the former enlargement of the aortic root the development of an aneurysm was seen and was resected in the sa...

To ensure that large precision instruments and equipment are in the best working condition, it is necessary to provide a suitable environment for them. At this time, there high requirement vibration of foundation at location. Measuring parameters, analyzing state, taking damping measures during construction process basis premise installation normal work. Combined with an application example, pa...

Blasting operations involve some undesirable environmental issues that may cause damage to equipment and surrounding areas. One of them, probably the most important one, is flyrock induced by blasting, where its accurate estimation before operation essential identify blasting zone’s safety zone. This study introduces several tree-based solutions for an prediction flyrock. has been done using fo...

Dry-ice particle blasting is similar to sand blasting, plastic bead blasting, or soda blasting where a media is accelerated in a pressurized air stream (or other inert gas) to impact the surface to be cleaned or prepared. With dry-ice blasting, the media that impacts the surface is solid carbon dioxide (CO2) particles. One unique aspect of using dry-ice particles as a blast media is that the pa...

Exposure data on biocides are relatively rare in published literature, especially for secondary exposure. This is also the case for antifouling exposure. Therefore, a field study was carried out measuring exposure to antifouling paints. Both primary exposure (rolling and spraying) and secondary exposure (during sand blasting) were studied. Exposure during rolling was measured in boatyards where...

UNLABELLED The purpose of this study was to evaluate and compare the effect of grit blasting, chemical treatment, and application of alloy primer combinations on the shear bond strength (SBS) of a self-cure resin cement to titanium surface. MATERIALS AND METHODS Fifty cast commercially pure titanium discs (9 mm × 2 mm) were divided into five groups (n = 10), which received the following surfa...
