This work describes the collection and properties of publicly available rock drill fault classification data set rockdrill11, used for 2022 PHM Conference Data Challenge. The is collected from a carefully instrumented hydraulic drill, operating in normal operation test cell while inducing number faults. Hydraulic pressure measured at 50kHz three different locations, resulting detailed signature...

Bone is a dense, mineral-rich tissue with organic components. Implants such as plates and nails are used to reconstruct fractures. In orthopedic surgery, broad-spectrum of drills ranges from pneumatic battery-operated electric drills. Each drill has its own set benefits drawbacks. Though the standard care, battery drill, costly, expense maintenance too high. Orthopedic surgeons frequently emplo...

Sometimes, the severe superior maxillary atrophy compromises and even impide oral implants treatment. The use of rotatory instruments (drills) produce heat and lost of bone, but the osteotomes in implantology avoid this and simplifies the surgical treatment allowing implant installation with an easier technique. We present an expansive maxillary technique review, describing the main indications...

Antifreeze thermal electric drills have a long history of ice drilling in temperate, subpolar and polar glaciers. Shallow, intermediate and deep ice cores have been obtained in Arctic, Antarctic and on high elevation glaciers. Many merits and drawbacks of antifreeze thermal technology have been discovered over the past 25 years. A modified version of the antifreeze thermal electric ice coring d...

This study examined the effect of the HamSprint Drills training programme and conventional football practice warm-up on lower limb neuromuscular control. The purpose-built active movement extent discrimination apparatus was used to assess lower limb neuromuscular control in 29 footballers from one professional Australian Football League club. Without vision of the contact point, participants pe...

The purpose of the present study was to investigate the apical seal of root canals filled with Ketac Endo glass ionomer cement with a single point or multiple points and partial removal of fillings using drills with or without water cooling. Ninety-six single-root teeth were instrumented and filled with Ketac Endo and gutta-percha. The single point procedure was used in 48 teeth and the multipl...

J Strength Cond Res 31(2): 435-444, 2017-The purpose of this study was to quantify the reliability of kinetic variables of British Army foot drill performance within untrained civilians and report the magnitude of vertical ground reac...

PURPOSE To determine whether a wire-guided single drill protocol could be utilized without causing an increase in bone temperature beyond those seen with the traditional techniques of sequential drilling with and without a drill guide. MATERIALS AND METHODS A bovine femoral bone model was used with thermocouples and infrared temperature measurements to record thermal increase of the bone and ...

In a domain such as space technology, where robustness, mass, volume and power efficiency are key, biological organisms may provide inspiration for new systems with high performance. By using micro-technology processes, designers of space systems may take advantage of the millions of years over which miniaturised mechanisms in plants and animals have been optimised for survival. Space explorati...

C atastrophes, natural or man-made, are very rare events in the life of hospitals in the developed world. None of the hospitals that coped with well known recent events such as Hurricane Katrina or the Madrid bombings had actually experienced or prepared for such an occurrence. A mass casualty incident (MCI), sometimes called “MASCAL,” is a situation in which a hospital receiving multiple casua...
