Spatio-temporal accident analysis for accident prevention in relation to behavioral factors in driving: the case of South Anatolian Motorway
(Elsevier Sci Ltd, 2015)Analyzing the pattern of traffic accidents on road segments can highlight the hazardous locations where the accidents occur frequently and help to determine problematic parts of the roads. The objective of this paper is ... -
Preparation and characterization of porous hydroxyapatite pellets: effects of calcination and sintering on the porous structure and mechanical properties
(Sage Publications Ltd, 2016)In this study, porous hydroxyapatite structures were produced by using urea particles of 600-850 mu m size. Samples with two different urea composition (25 and 50 wt%) were prepared along with samples without any urea ... -
Prediction of bacterial virulent proteins with composition moment vector feature encoding method
(E D P Sciences, 2016)Prediction of bacterial virulent proteins is critical for vaccine development and understanding of virulence mechanisms in pathogens. For this purpose, a number of feature encoding methods based on sequences and evolutionary ... -

Gathering road safety critical information from users
(Igi Global, 2017)Traffic roads are a core element of GIS and many volunteered systems like openstreetmaps have the goal to make road data publicly available. Road users collecting geographical information and sharing them according some ... -
A new spectroscopic imager for X-rays from 0.5 keV to 150 keV combining a pnCCD and a columnar CsI(Tl) scintillator
(Iop Publishing Ltd, 2017)By combining a low noise fully depleted pnCCD detector with a columnar CsI(Tl) scintillator an energy dispersive spatial resolving detector can be realized with a high quantum efficiency in the range from below 0.5 keV to ... -
A lyapunov based model reference adaptive control of a quadrotor
(Ieee, 2017)Model reference adaptive controller is proposed to control the position of a quadrotor with uncertain model parameters. The controller design procedure is provided considering position and attitude dynamics as outer and ... -
SAR moving object imaging using sparsity imposing priors
(Springer, 2017)Synthetic aperture radar (SAR) returns from a scene with motion can be viewed as data from a stationary scene, but with phase errors due to motion. Based on this perspective, we formulate the problem of SAR imaging of ... -
Mechanical characterization of B4C reinforced aluminum matrix composites produced by squeeze casting
(Cambridge Univ Press, 2017)Boron carbide (B4C) ceramic particles were used as reinforcement material to produce aluminum (Al) matrix composites by squeeze casting method. Four different B4C contents as 0, 3, 5, and 10 wt%, and three different squeeze ... -
Single-shot full strain tensor determination with microbeam X-ray Laue diffraction and a two-imensional energy-dispersive detector
(Int Union Crystallography, 2017)The full strain and stress tensor determination in a triaxially stressed single crystal using X-ray diffraction requires a series of lattice spacing measurements at different crystal orientations. This can be achieved using ... -
Comparison of deep drawability of AA5754-H22 and AA6061-T6 aluminum alloys for automotive applications
