Resonance frequency analysis (RFA) is the most extended method for measuring implant stability. The stability quotient (ISQ) measure obtained by different RFA devices; however, inter- and intra-rater reliability agreement of these instruments remain unknown. Thirty implants were placed in three pig mandibles. ISQ was measured parallel perpendicular (lingual) to peg axis with Osstell® Beacon, Pe...

Contour Advection with Surgery (CAS) is used to simulate turbulent premixed combustion. This paper presents results from calculations of methane/air mixtures and ethylene/air mixtures with equivalence ratios ranging from 0.8 to 1.6 with different turbulence intensities. The positions, thicknesses and half-angles of the turbulent flame zones are compared for each case by plotting contour maps of...

A growing number of location-based applications are based on indoor positioning, and much of the research effort in this field has focused on the pattern-matching approach. This approach relies on comparing a pre-trained database (or radio map) with the received signal strength (RSS) of a mobile device. However, such methods are highly sensitive to environmental dynamics. A number of solutions ...

Moving target search (MTS) or the game of cops and robbers has a broad field of application reaching from law enforcement to computer games. Within the recent years research has focused on computing move policies for one or multiple pursuers (cops). The present work motivates to extend this perspective to both sides, thus developing algorithms for the target (robber). We investigate the game wi...

This paper presents Beacon, a technique that exploits the advantages of IP multicast to provide a low overhead system for network topology monitoring. Beacon is a self-organizing system which builds a self similar network topology that enables the system to converge very quickly even at a high degree of scalability. Another property of the Beacon system is that it does not require any interdoma...

This paper studies the problem of determining the position of beacon nodes in Local Positioning Systems (LPSs), for which there are no inter-beacon distance measurements available and neither the mobile node nor any of the stationary nodes have positioning or odometry information. The common solution is implemented using a mobile node capable of measuring its distance to the stationary beacon n...

In this paper, we develop a method to check the schedulability superframe with beacon-enabled mode in ISA100.11a Wireless Industrial Networks environment. Maximum length of time slot is added in the superframe to reduce the overhead, and deadline monotonic scheduling approach is proposed to analyze the system scenario. The simulation results indicate that our proposed method required less numbe...

Abstract A path planning for mobile beacon nodes is presented based on the node localization problem of WSN. The beacon nodes define the unknown node position by using ranging method of RSSI. By analyzing defects of a static trajectory, random trajectory, the beacon nodes move to the maximum coverage of unlocated nodes. The simulation result demonstrates that this algorithm obtains good localiz...

HE term “prealbumin” was originally applied by SMITHIES (1955) to those zones of protein which migrate ahead of albumin in alkaline starch gel. Using acidic starch gel, BRAEND and EFREMOV (1965) and GAHNE (1966) detected numerous protein zones in horse serum that migrated ahead of albumin. Also, FAGERHOL and BRAEND (1965) demonstrated a multiplicity of prealbumin zones in human serum. GAHNE (19...

in recent years, the topic of desertification has been discussed in different ways in scientific areas. this event occurred globally, regionally and nationally and many steps were taken to stop it. desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. the identification of sensitive regions and prevention ...
