Traffic accidents occur frequently every year. Skid-resistance performance is an important indicator in evaluating road safety. In this paper, the surface texture information obtained by a line laser scanner. The original two-dimensional (2D) signal decomposed into eight intrinsic mode functions complementary ensemble empirical decomposition (CEEMD). Eight compose 800 × 8 data matrix. matrix si...

Epoxy plastic, a form of epoxy resin, is widely employed in variety sectors due to its superior mechanical qualities and adaptability. The application waste plastic urban highway construction has been major topic study. To conduct this study, polymers are mixed with concrete enhance the thermal compressive resistance tensile strength, which acts as substitute for conventional cements. experimen...

The sensitivity of the pendulum test to variation in spasticity in persons with spastic cerebral palsy (CP) was tested in 30 participants with CP and 10 participants without CP (controls) (mean age 13.8 years). The participants with CP were classified into three groups, with normal (mean age 15.9 years), mild/moderate (13.0 years), or severe (23.0 years) muscle tone, as assessed clinically usin...

In this study, aggregates in asphalt concrete were partially replaced by basic oxygen furnace slag (BOFS) proportions of 45 wt.%, 55 and 75 wt.%. The thermal performances the specimens are discussed based on conductivity, emissivity, indoor outdoor temperature measurements. Consequently, wt.% specimen’s BOFS, which had a high emissivity 0.86 across sky window. tests, change was recorded to esti...

This paper summarizes the mechanical and control design concepts of an inverted or unstable pendulum where stabilization is achieved by a moment exchange generated by a controlled symmetric rotation of a rotational inertia attached to the pendulum. The proposed design of the pendulum has a fixed bottom rotation or point of support as opposed to the usual vertically or horizontally moving point ...

Poor braking performance on runways during winter is one of the most significant factors causing runway excursions. The International Civil Aviation Organization (ICAO) proposed a standardized method, named Global Reporting Format (GRF), to establish surface conditions based human observers. GRF includes description conditions. This work aimed at reproducing in laboratory, and monitor effect co...

Construction and demolition waste (CDW) materials account for a considerable part of throughout the world. As these are not usually recycled, reusing them in construction projects is major significance. In this study, recycled concrete, bricks, glass were used as 100% aggregates chip seal, which corrective or preventive pavement maintenance method. A cationic rapid setting (CRS-2) bitumen emuls...

this paper proposes an approach for the minimum time swing upof a rotary inverted pendulum. our rotary inverted pendulum is supported bya pivot arm. the pivot arm rotates in a horizontal plane by means of a servomotor. the opposite end of the arm is instrumented with a joint whose axisis along the radial direction of the motor. a pendulum is suspended at thejoint. the task is to design a contro...

" An apparatus for the measurement of liquid complex shear viscosity in the frequency range 80-2500 Hz, with the use of a torsion pendulum operating in forced oscillation, is described. The drive and detection system consists of a magnet inside the pendulum, two excitation and two measuring coils. The determination of the complex shear viscosity is based on the measurement of the resonance freq...
