Abstract. This paper presents a method to build up statically admissible slip-line field and, as a result, the field of statically admissible stresses of plane-strain compression of a three-layer symmetric strip consisting of two different rigid perfectly plastic materials between rough, parallel, rigid plates The case is considered when the she...

Abstract This study proposes a numerical model based on the depth-integrated non-hydrostatic shallow water equations with an improvement of wave breaking dissipation. Firstly, studies of parameter sensitivity were carried out using the proposed numerical model for simulation of wave breaking to understand the effects of the parameters of the br...

Abstract. Based on the circle assemblage model, the effective properties of the inclusion with imperfect interface are derived. The equivalent inclusion is incorporated in the Fourier Transform algorithm to determine the effective conductivity of the composite with lowly conducting or highly conducting interface. The size effect is considered for...

Abstract. Nanocomposites of graphene oxide (GO) and tungsten oxide (WO3) nanobricks were synthesized by co-dispersing graphene oxide and tungsten oxide nanobricks in bi-distilled water with different weight ratios (0.1, 0.3 and 0.5 wt.% of graphene oxide). The ammonia gas sensing properties of nanocomposites were studied at low temperatures (50,...

Abstract. This paper presents free vibration analysis of functionally graded (FG) porous nanoplates based on isogeometric approach. Based on a modified power-law function, material properties are given. The nonlocal elasticity is used to capture size effects. According to a combination of the Hamilton’s principle and the higher order shear defor...

Abstract. Load applied to the connecting-rod and the pressure in the lubricant oil film change the stress in the connecting-rod during the operating cycle. This problem is one of the characteristics we need to consider when studying the connecting-rod big end bearing. A specific experimental device and the connecting-rod model of photoelastic ma...

Abstract – Glaucoma and diabetic retinopathy (DR) are the two most common retinal related diseases occurred in the world. Glaucoma can be diagnosed by measuring optic cup to disc ratio (CDR) defined as optic cup to optic disc vertical diameter ratio of retinal fundus image. A computer based optic disc is expected to assist the ophthalmologist t...

Abstract – The objective of this research is to design an adaptive model for multipaths communication channels. To evaluate the performance of the model, the authors used two indicators, namely the attainment of a minimum value of error signals in the form of interface and echo on the channel, and Filter Finite Impulse Response (FIR) has the sa...
