Neutron diffraction has been used to determine the residual stresses in the weld region of laser-welded tailor-welded blank (TWB) samples. Residual stresses in same gauge and differential gauge TWB samples are examined in the as-welded condition as well as after uniaxial loading to 0.5, 3.0 and 7.0% strain. Results indicate that stress distribution

In this paper, an array of microstrip patch array antenna has been designed and simulated for 5G applications at 28 GHz. Beamforming which requires pattern analysis remain significant especially for 5G communication as it is able to mitigate high path loss at high frequency. Thus, an accurate pattern analysis is essential in order to obtain accurat

Generally peak-to-average power ratio (PAPR) reduction imposes transmission performante degradation or system capacity reduction. This paper proposes a method for reducing the P APR of OFDM signals by combining carrier Interferometry (Cf) spreading code and iterative processing (IP). The proposed method is capable of reducing the PAPR significantly

Changes to electrical (I-V and C-V) characteristics of diodes may also be modified due to application in extreme radiation environment. Silicon (Si) and Gallium Arsenide (GaAs) commercial diodes were irradiated at low and high dose neutron radiatin. Current-voltage (I-V) measurements at low dose irradiation show a decrease in forward (FB) and rever

In this paper we consider a set of all extremal Volterra quadratic stochastic operators on three dimensional simplex S3, show that this set is parted into four equivalence classes with respect to group of transformations generated by permutations and describe the behaviour of trajectories extremal Volterra quadratic stochastic operators for each cl

We consider an Ising model on a Cayley tree with competing interactions of the next-nearest-neighbours of two types: prolonged and one-level interactions only. More recently, Ganikhodjaev and Zakaria investigated the same model and proved that its phase diagram contain only four phases, namely, ferromagnetic, paramagnetic, antiferromagnetic and ant

We consider simple version of the Blume-Emery-Griffiths model on the Cayley tree and investigate the problem of phase transition using the exact recursion equations for the Cayley tree of second order, so that every spin has three nearest neighbours. These equations are studied analytical-ly for D>0 and J>0. It is proved that one can reach

A blood group provides an ideal opportunity for the study of human variation without cultural prejudice. It can be easily classified for many different genetically inherited blood typing systems. Also significant is the fact that we rarely take blood types into consideration in selecting mates. A few people know their own type today and no one did

We study the phase diagrams for the Potts model with restricted competing nearest-neighbor interactions J1 and ternary interactions Jpt on a Cayley tree of arbitrary order k. At vanishing temperature, the phase diagram is fully determined for all values and signs of Jpt/J1 and T/J1. The phase diagrams are obtained from stability conditions, and cha
