In today’s rapid widespread of digital technologies into all live aspects to enhance efficiency and productivity on the one hand and on the other hand ensure customer engagement, personal data counterfeiting has become a major concern for businesses and end-users. One solution to ensure data security is encryption, where keys are central. There is therefore a need to find robusts key generation implementation that is effective, inexpensive and non-invasive for protecting and preventing data counterfeiting. In this paper, we use the theory of electromagnetic wave propagation to generate encryption keys.

Traditional welding methods are limited in low heat input to workpiece and high welding wire melting rate. Twin-wire indirect arc（TWIA） welding is a new welding method characterized by high melting rate and low heat input. This method uses two wires one connected to the negative electrode and another to the positive electrode of a direct-current（DC） power source. The workpiece is an independent, non-connected unit. A three dimensional finite element model of TWIA is devised. Electric and magnetic fields are calculated and their influence upon TWIA behavior and the welding process is discussed. The results show that with a 100 A welding current, the maximum temperature reached is 17 758 K, arc voltage is 14.646 V while maximum current density was 61 A/mm2 with a maximum Lorene force of 84.5 ~tN. The above mentioned arc parameters near the cathode and anode regions are far higher than those in the arc column region. The Lorene force is the key reason for plasma velocity direction deviated and charged particles flowed in the channel formed by the cathode, anode and upper part of arc column regions. This led to most of the energy being supplied to the polar and upper part of arc column regions. The interaction between electric and magnetic fields is a major determinant in shaping TWIA as well as heat input on the workpiece. This is a first study of electromagnetic characteristics and their influences in the TWIA welding process, and it is significant in both a theoretical and practical sense.

SiC-Fe composites are prepared by metal organic chemical vapor deposition （MOCVD） using silicon carbide （SIC＇） and iron pentacarbonyl （Fe（CO）5） as the precursors. The structure and morphology analyses demonstrate that the Fe nanoparticles have been deposited on the surface of the SiC particles. In terms of reflection loss （RL）, the absorbing frequency band （AFB, the value of RL 〈 -10 dB）, and the matching thickness （tin）, SiC-Fe composites show the best performances： minimum RL of - 31.6 dB with tm= 2.0 mm at 15.1 GHz, AFB of 12.9-17.3 OHz, indicating that Fe-doped SiC by MOCVD can significantly improve the electromagnetic properties of SiC and that SiC-Fe composites could be used as an effective microwave absorption materiM.

In order to obtain cast metal of high quality, an investigation was carried out by simultaneous imposition of multi electromagnetic fields from the outside of a cold crucible copper mold. Sn 4.5%Pb as a simulator of high melting point metal was continuously cast under different conditions. The results show that multi electromagnetic fields can eliminate surface defects, and coarse columnar grains of the solidification structure is turned into equiaxed crystal with the increase of magnetic flux density. Moreover, finer equiaxed crystal structure is obtained when rapidly solidified sheet is fed into the mold during continuous casting.[

electromagnetic(EM) missile sources have so far been limited to the cases where the spatial distribution of current density is either a straight line or a circular disk or a rectangle. It may then be questioned whether an arbitrary linear current distribution or an arbitrary surface current distribution can be used as a launcher of the EM missiles. In this paper the above question is answered, and we have demonstrated that an arbitrary linear or an arbitrary surface current distribution of finite size has the ability to launch an EM missile, i. e. to realize slow decrease of electromagnetic energy on any axis so long as the axis has an intersection point with the source region, and in the neighborhood of this point the spatial distributions of the current are locally flat and perpendicular to the axis.

With taking electromagnetic field into account for the transport model of Boltzmann-Uehling-Uhlenbeck,electromagnetic effects are studied for ^(208)Pb +^(208)Pb collisions around 100A MeV. electromagnetic field evolution during the collisions was estimated. It was found that the electric field has an obvious effect on the transverse momentum(p_T) spectra of nucleons during heavy ion collisions, and leads to different minimum position for the peak of p_T spectra of nucleons versus beam energy when the electric field is switched on. For the magnetic field, it affects the z-axis direction distributions of nucleons for central heavy ion collisions at lower energy.

Wireless capsule endoscopy(WCE) is a promising technique which has overcome some limitations of traditional diagnosing tools, such as the comfortlessness of the cables and the inability of examining small intestine section. However, this technique is still far from mature and asks for the feasible improvements. For example, the relatively low transmission data rate and the absence of the real-time localization information of the capsule are all important issues. The studies of them rely on the understanding of the electromagnetic wave propagation in human body. Investigation of performance of WCE communication system was carried out by studying electromagnetic(EM) wave propagation of the wireless capsule endoscopy transmission channel. Starting with a pair of antennas working in a human body mimic environment, the signal transmissions and attenuations were examined. The relationship between the signal attenuation and the capsule(transmitter) position, and direction was also evaluated. These results provide important information for real-time localization of the capsule. Moreover, the pair of antennas and the human body were treated as a transmission channel, on which the binary amplitude shift keying(BASK) modulation scheme was used. The relationship between the modulation scheme, data rate and bit error rate was also determined in the case of BASK. With the obtained studies, it make possible to provide valuable information for further studies on the selection of the modulation scheme and the real-time localization of the capsules.
