This paper presents a software prototype of wireless network for the Internet Things (IoT) based on DECT (Digital Enhanced Cordless Telecommunication) standard. It proposes an architecture encapsulating commands from most common IoT protocol, MQTT (Message Queuing Telemetry Transport), into SIP (Session Initiation Protocol) packets. A module is created to embed MQTT-SN (MQTT Sensor Networks) pa...

The sound produced by a dental air turbine handpiece (dental drill) can markedly influence the sound environment in a dental clinic. Indeed, many patients report that the sound of a dental drill elicits an unpleasant feeling. Although several manufacturers have attempted to reduce the sound pressure levels produced by dental drills during idling based on ISO 14457, the sound emitted by such dri...

*Department of P.O.P, college of dentistry, university of Mosul, Mosul, Iraq. Introduction Conservation of anchorage in totality has been a perennial problem to the traditional orthodontist. Conventional means of supporting anchorage have been used by either intra oral sites or relying on extra oral means. Both of these have their limitations. The extra oral forces very difficult device and som...

Recently there has been a considerable effort devoted to intelligent joint speech coding and iorward error correction (FEC) coding [I] as well as to equal [2] and un-equal protection coded modulation [3]. In reference [4] Hagenauer introduced an intelligent framework for considering source significance-, channel stateand decoder reliability-information in order to achieve the best possible perf...

Sometimes called radio in the loop (RITL) or fixed-radio access (FRA), wireless local loop (WLL) is a system that connects subscribers to the public switched telephone network (PSTN) using radio signals as a substitute for copper for all or part of the connection between the subscriber and the switch. This includes cordless access systems, proprietary fixed radio access, and fixed cellular syst...

BACKGROUND The use of cellular and cordless telephones has increased dramatically during the last decade. There is concern of health problems such as malignant diseases due to microwave exposure during the use of these devices. The brain is the main target organ. METHODS Since the second part of the 1990's we have performed six case-control studies on this topic encompassing use of both cellu...

Drilling is an hole making process in metal cutting operation performed by extrusion which finds wide application in various industries for manufacturing components using metals and non metals. This process is applied widely in assembly of components or elements, where processing challenges are severe issue such as to maintain surface integrity, ovality, machining time, Metal Removal Rate etc.,...

OBJECTIVE Percutaneous cochlear implant surgery consists of a single drill path from the lateral mastoid cortex to the cochlea via the facial recess. We sought to clinically validate this technique in patients undergoing traditional cochlear implant surgery. STUDY DESIGN Prospective clinical trial. METHODS After institutional regulatory board-approved protocols, five ears were studied via t...

BACKGROUND Dacrocystorhinostomy (DCR) is an operation used to treat nasolacrimal duct obstruction. Essentially there are two approaches: external and endoscopic. Several modalities are used in endoscopic DCR; all aiming to improve success rate, reduce complications, and shorten operative time. Both kerrison punch and drill are widely used in endoscopic DCR with non-conclusive knowledge about di...
