Full-scale/model test comparison studies to validate the traditional atmospheric boundary layer (ABL) wind tunnel simulation technique are reviewed. According to the literature review, notable discrepancies between full-scale measurement results and model test results were observed by most performed comparison studies, but the causes of the observed discrepancies were not revealed in a scientif...

In North America, Most power distribution systems employ a four-wire multi-grounded neutral (MGN) design. This paper has explained the inherent characteristics of multi-grounded three-phase four-wire distribution systems under unbalanced situations. As a result, the mechanism of voltage swell and voltage sag in MGN feeders becomes difficult to understand. The simulation tool that has been used ...

This paper proposes a low decoding complexity, full-diversity and full-rate space-time block code (STBC) for 4 transmit and 2 receive (4 × 2) multiple-input multiple-output (MIMO) systems. For such systems, the best code known is the DjABBA code and recently, Biglieri, Hong and Viterbo have proposed another STBC (BHV code) which has lower decoding complexity than DjABBA but does not have full-d...

The article describes numerical method of physical gas flow parameters recovery at gas trunkline and distribution pipeline networks. The information about full-scale measurements of time dependences of gas flow parameters at defined points inside pipeline networks and at its boundaries is the base for recovery implementation. Numerical simulation is carried out by defining and solving an optimi...

Modelling and simulation of semi-autogenous (SAG) mills are valuable tools for helping to design control laws for a given application and subsequently to optimise its performance and process control. SAG mills (see Figure 1) are presently one of the most widely used alternatives in the field of mineral size reduction as a result of their advantages such as higher processing capacity, lower phys...

A full scale aircraft lightning test campaign was conducted to support compliance with AWM 525.981 through validation of computational electromagnetic (CEM) models. The aircraft is injected with different lighting current attachment scenarios while measurements of currents, voltages and magnetic fields focused in the composite wing area. The high fidelity aircraft model has been resolved with E...

The purpose of the Local Effect Model (LEM) is to calculate the dose dependent relative biological effectiveness (RBE) of charged particle radiation with respect to conventional photon radiation [1]. Because of computation time reasons, this is done within a low fluence approximation where the biological damage of a radiation field at arbitrarily high irradiation fluence is deduced from the dos...

Main challenges in electromagnetic interference (EMI) modeling and simulation for modern and future wireless communication systems and networks are addressed in this paper. It is emphasized that there exists a big difference between simulating analog and digitally-modulated systems. A computationally-efficient approach for the EMI analysis of wireless systems and networks by behavioural-level n...

The third phase of the Sudbury Neutrino Observatory (SNO) experiment added an array of 3He proportional counters to the detector. The purpose of this neutral-current detection (NCD) array was to observe neutrons resulting from neutral-current solar-neutrino–deuteron interactions. We have developed a detailed simulation of current pulses from NCD array proportional counters, from the primary neu...

In this paper, we survey various designs of low-power full-adder cells from conventional CMOS to really inventive XOR-based designs. We further describe simulation experiments that compare the surveyed full-adder cells. The experiments simulate all combinations of input transitions and consequently determine the delay and power consumption for the various full-adder cells. Moreover, the simulat...
