Forest operations often enhance runoff and soil loss in roads skid trails, where cut slopes fill are the most important source of sediment. This study evaluated effectiveness four erosion control treatments applied to slope segments forest different ages Hyrcanian northern Iran. The treatment combinations, each replicated three times, included classes mulch cover (bare [BS], wood chips [WCH], s...

Skid‐steered mobile robots have been widely used in exploring unknown environments and in military applications. In this paper, the tuning fuzzy Vector Field Orientation (FVFO) feedback control method is proposed for a four track wheel skid‐steered mobile robot (4‐TW SSMR) using flexible fuzzy logic control (FLC). The extended Kalman filter is utilized to e...

Pavement frictional characteristics are commonly determined by conducting skid tests in accordance with ASTM Standard E274. The results of these tests [skid number (SN)] are used in ranking roads to establish construction priorities and to estimate tirepavement friction in accident analysis. The role of SN in these two applications is addressed. There are serious limitations constraining the us...

Extreme skin depth engineering (e-skid) can be applied to integrated photonics manipulate the evanescent field of a waveguide. Here we demonstrate that e-skid implemented in two directions order deterministically engineer wave allowing for dense integration with enhanced functionalities. In particular, by increasing depth, enable creation large gap, bendless directional couplers operational ban...

Articulated tracked vehicles have been traditionally studied and appreciated for the extreme maneuverability mobility flexibility in terms of grade side slope capabilities. The articulation joint represents an attractive advantageous solution, if compared to traditional skid steering operation, by avoiding any trust adjustment between outside inside tracks. This paper focuses on analysis contro...

In the second direction, accompanying this outdoor ex­ posure, will be the standard laboratory tests on these same materials after they have been subjected to freezing and thaw­ ing, wetting and drying. Such laboratory work will, when compared to the outdoor experiment, tell us whether or not it is necessary to go through the actual construction of a test road in order to find out what may othe...

The control of planetary rovers, which are high performance mobile robots that move on deformable rough terrain, is a challenging problem. Taking lateral skid into account, this paper presents a rough terrain model and nonholonomic kinematics model for planetary rovers. An approach is proposed in which the reference path is generated according to the planned path by combining look-ahead distanc...

Recreation is one of the anthropogenic factors negative impact on natural environment Ukrainian Carpathians and, above all, complexes national parks region. In this regard, Carpathian NPP with a developed recreational infrastructure – network tourist routes and stationary recreation areas an indicative example. Excessive load causes digression activation erosion processes routes. It was establi...
