Background Rough and/or plasma-activated abutments seem to be able increase soft tissue adhesion and stability; however, limited evidence is available about bacterial contamination differences. Purpose The aim was investigate the oral microbiota on four dental with different surfaces by quantitative real-time polymerase chain reaction (qRT-PCR) culturomic approach. Methods Forty patients needin...

We consider the problem of active reduction of the structural vibrations induced by the sloshing of large masses of fuel inside a partly full tank. The proposed study focuses on an experimental device mimicking an aircraft wing made of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid. After deri...

This paper proposes a joint source-channel coding (JSCC) technique that well utilizes multi-dimensional (MD) source correlation using MD single parity check codes (MD-SPCCs). The source is assumed to be described by the coupling of multiple first-order binary Markov processes. The knowledge about the source correlation is utilized in the channel decoding process where each component decoder uti...

PURPOSE This study aimed to evaluate the effect of implant thread depth on primary stability in low density bone. MATERIALS AND METHODS The insertion torque was measured by inserting Ti implants with different thread depths into solid rigid polyurethane blocks (Sawbones) with three different bone densities (0.16 g/cm(3), 0.24 g/cm(3), and 0.32 g/cm(3)). The insertion torque value was evaluate...

During the 88th and 96th Conferences of the Working Committee of the Surveying Authorities of the States of the Federal Republic of Germany (AdV) in 1991 and 1995 the resolution was passed to introduce the European Terrestrial Reference System 1989 (ETRS89) with the universal transversals Mercator projection (UTM) as map projection of GRS80 Ellipsoid in Germany and Europe uniformly. The task of...

As the usability of and demand for unmanned aerial vehicles (UAVs) have increased, it has become necessary to establish a UAS traffic management (UTM) system efficient UAV operations at low altitudes. To avoid collisions with ground obstacles, other UAVs, manned aircraft, in building safe path, UTM needs determine time space allocated each flight. Ideas discretizing structuring airspace various...

EuroDRONE is an Unmanned Traffic Management (UTM) demonstration project, funded by the EU’s SESAR organization, and its aim to test validate key UTM technologies for Europe’s ‘U-Space’ program. The architecture comprises cloud software (DroNav) hardware (transponder) be installed on drones. proposed system a Highly Automated Air System small UAVs operating at low altitudes. It sophisticated, se...

Unmanned Aircraft Systems (UAS) Traffic Management (UTM) is an active research subject as its proposed applications are increasing. UTM aims to enable a variety of UAS operations, including package delivery, infrastructure inspection, and emergency missions. That creates the need for extensive on how incorporate such traffic, conventional methods operations used in Air (ATM) not suitable constr...

In the Deep-drawing process, a blank is drawn into hollow element taking shape of die by operation punch. This process has numerous advantages and applications in automobile, aerospace, kitchenware, packaging industries. The primary purpose this study to design simulate deep drawing LS-Dyna PrePost(R) V4.6.17 using Johnson-Cook flow stress as material model. An appropriate judicious characteriz...

1111001-8484 IJCEE-IJENS © February 2011 IJENS I J E N S  Abstract— Despite the recreational parks in Universiti Teknologi Malaysia (UTM), many students are still facing difficulties in accessing these recreational parks within the campus because their locations and distances are not favorable for the students to access them from their on campus residential areas. Moreover, despite the enactme...
