The purpose of this paper is to investigate the exposure of human workers to low and high frequency electromagnetic fields during operation of GMAW‐P welding machines.

First, a numerical parametric analysis of the current waveform has been performed in Matlab, with reference to the human exposure; then a simulation model of a full welding system has been implemented in Simulink/Matlab. The effect has been numerically quantified accordingly to European Standards EN 50444 and EN 50445.

Contributions to human exposure of specific parts of the current waveform have been evaluated. A new numerical implementation of a full welding system has been done.

The paper shows that there could possibly be improvement in the design of current waveforms, with respect to a reduced human exposure of workers to electromagnetic fields.

The paper presents a new numerical tool that can be useful since the design phase of a welding system for the evaluation of human exposure of workers to electromagnetic fields.

The aim of the work was to obtain an auxiliary instrument able to give the magnetic configuration of a magnetron sputtering device for operation with targets, magnetic and non magnetic, with different heights, starting from a device with no detailed information of the source.

An inverse problem has been dealt with. A 2D numerical analysis has been performed, which utilizes as a starting point a model identified with a simple analytical procedure based on measurements.

A satisfactory equivalent model has been identified, and validated in several different conditions.

The proposed approach can be applied when no detailed information of the source is available, in the case of a cathode without a ferromagnetic yoke.

The purpose of this paper is to obtain a multidisciplinary characterization of nanostructured copper films for electromagnetic shields.

Structural and electrical analysis have been applied, on copper nanometric films produced by a magnetron sputtering device.

Data are provided for copper films realized by magnetron sputtering deposition on glass, in different operating conditions.

A multidisciplinary comprehension of shielding effectiveness of nanostructured thin films can be important in many applications where there are electromagnetic compatibility problems.

The paper gives a valuable set of information for the characterization of nanometric copper thin films.

The purpose of this paper is to propose a numerical algorithm able to describe the Stackelberg strategy for a multi level hierarchical three-person game via genetic algorithm (GA) evolution process. There is only one player for each hierarchical level: there is an upper level leader (player L0), an intermediate level leader (player L1) who acts as a follower for L0 and as a leader for the lower level player (player F) that is the sole actual follower of this situation.

The paper presents a computational result via GA approach. The idea of the Stackelberg-GA is to bring together GAs and Stackelberg strategy in order to process a GA to build the Stackelberg strategy. Any player acting as a follower makes his decision at each step of the evolutionary process, playing a simple optimization problem whose solution is supposed to be unique.

A GA procedure to compute the Stackelberg equilibrium of the three-level hierarchical problem is given. An application to a Authority-Provider-User (APU) model in the context of wireless networks is discussed. The algorithm convergence is illustrated by means of some test cases.

The solution to each level of hierarchy is supposed to be unique.

The paper demonstrates the possibility of using computational procedures based on GAs in hierarchical three level decision problems extending previous results obtained in the classical two level case.

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.
