In this study, small fraction of NiTi (5 wt%) was added to Yttria stabilized zirconia (YSZ) top coat to improve it sliding wear resistance. The measurement of width of wear tracks after wear tests under a 15 N load for 100 m sliding distances showed that the width of wear track in NiTi-YSZ coating is shorter than that in YSZ coating which depicts the higher wear resistance of NiTi-YSZ coa...

The present paper deals with the experimental investigation of interlocking effect crushed stone ballast material, assessing it as relationship residual and dynamic stresses under layer during laboratory tests consideration different boundary conditions. experiments were executed a scaled model sleeper. measured pressure at bottom surface has two parts: residual. part depends on external loadin...

The detection and identification of Resident Space Objects (RSOs) from survey tracks requires robust efficient orbit determination methods for the association observations same RSO. Both Initial Orbit Determination (IOD) (OD) perform orbital estimation in which relies. choice proper IOD OD is essential whole data association, since they are charge providing required to evaluate figure merit ass...

A depth-resolved Raman spectroscopy technique was used to study the residual stress profiles in polycrystalline silicon nitride that irradiated with Xe (167 MeV, 1 × 1011 cm−2 ÷ 4.87 1013 cm−2) and Bi (710 ions. It shown both compressive tensile fields were formed specimen, separated by a buffer zone located at depth coincided thickness of layer, amorphized due multiple overlapping track region...

When rails are laid in a railway track, small gaps are left between the ends of adjoining rails to allow for the expansion of the rails when the temperature rises. Rail joints are provided to form a continuous rail path which are normally laid in standard lengths bolted together by fishplates. When two rail joints are exactly opposing each other, they are called square &#10&#10(side by side) jo...

This paper develops methods for associating two sets of sensor tracks in the presence of missing tracks and translation bias. Key results include (1) Extension of the Maximum A Posteriori Probability method of matching tracks to use feature information as well as kinematic information; (2) translation bias removal techniques that are computationally tractable for large numbers of tracks, and ef...

This paper presents a easy to read review of the architectures for track-to-track fusion (T2TF). Based on whether the fusion algorithm uses the track estimates from the previous fusion and the configuration of information feedback, T2TF is categorized into six configurations, namely, T2TF with no memory with no, partial and full information feedback, and T2TF with memory with no, partial and fu...
