A preliminary study was conducted on the development of an intelligent dental handpiece with functionality to detect subtle changes in mechanical properties of tooth tissue during milling. Such equipment would be able to adopt changes in cutting parameters and make real-time measurements to avoid tooth tissue damage caused by overexertion and overextension of the cutting tool. A modified dental...

Abrasive waterjet cutting nowadays represents cold precise, computer controlled shape cutting without any strain [1, 2]. These attributes pose this technology to the position of permanent use in the future, that represents excellent perspective for expansion in volume sectors, especially there, where the materials with excellent utility properties are used [3, 4]. The AWJ technology is, under e...

In fact, the therapeutic benefits of cold temperature, particularly its analgesic and anti-inflammatory effects, were discovered by the ancient Egyptians and the Greek physician Hippocrates (Dawber & Cooper, 2001). Such intervention has evolved from the simple application of ice packs to the development of cutting edge equipment which utilizes the concept involving the effects of cold temperatu...

Metal matrix composites (MMCs) attract considerable attention as a result from its ability in providing a high strength, high modulus, high toughness, high impact properties, improving wear resistance and providing good corrosion resistance compared to unreinforced alloy. Aluminium Silicon (Al/Si) alloy MMC has been widely used in various industrial sectors such as in transportation, domestic e...

The Maintenance and Reliability Center (MRC) at The University of Tennessee, performs research and applies cutting-edge technology to help its member companies reduce losses caused by equipment downtime. The first MRC research project dealt with the precision alignment of rotating machinery. Controlled experiments were performed at The University of Tennessee and at the Oak Ridge Center for Ele...

Alex Muncy was still an apprentice at STIHL Inc. when the company enlisted him in revamping an automated packaging process. The package would contain the outdoor power equipment manufacturer’s signature trimmer line, the colorful cord used to give lawns a precise, neat appearance. The goal: satisfy the customer while cutting production costs. Muncy’s team developed a concept, designed the packa...

Traditionally, it has been difficult to compare the clinical performance of carbide dental burs. The purpose of this laboratory study was to investigate the comparative cutting efficiency of number 330 dental burs from six manufacturers. These burs were tested utilizing custom-built equipment consisting of a frictionless air sled to which the Macor substrate was attached. The substrate was fed ...

Cutting and packing problems appear in many industrial settings where larger pieces are cut into smaller ones in order to produce items or products that are required by other industries or customers, e.g., paper, steel and fiber industries. A solution for the cutting problem consists in determining a group of patterns and their frequencies, that is, the number of times that a pattern is cut to ...

This paper discusses cake-cutting protocols when the cake is a heterogeneous good, represented by an interval on the real line. We propose a new desirable property, the meta-envy-freeness of cake-cutting, which has not been formally considered before. Meta-envy-free means there is no envy on role assignments, that is, no party wants to exchange his/her role in the protocol with the one of any o...
