Abstract

In the current work, the characteristics of the high energetic proton events were studied. We have selected 40 energetic proton events with intensities of two order of magnitude over the background in the logarithmic scale at 90-116 MeV detected by Energetic and Relativistic Nuclei and Electrons (ERNE) onboard SOHO during solar cycle 23. We examine the first injection time of those events through two methods, first by estimating the flight time of non-scattered protons of those nominal energies along the Archimedean field line of nominal length 1.2 AU. Secondly, we consider wide range of proton energies for the same events and assume a simultaneous release, and that the path length does not depend on the energies. We then compared the estimated times and heights with related flare and coronal mass ejection (CME) characteristics. We found that all events were associated with Coronal Mass Ejections (CMEs) observed simultaneously with Large Angle and Spectrometric Coronagraph (LASCO) and solar flares observed with soft X-ray telescope onboard GOES. The speed and angular width is higher for those CMEs which were associated with X class flare than those which were associated with M class flare and C class flare. Most of the first protons injected while the CMEs were below 5 solar radii and most of the protons reach their maximum intensity while the CMEs were above 10 solar radii and that the maximum intensities have been achieved much earlier than the possible IP shock passage.

Abstract

In this study, In2O3 was prepared by reaction of indium acetate as precursor. The physical properties of the film were characterized by XRD, SEM, AFM, UV–visible thin film and FTIR spectroscopy measurements. The complete vibration analysis was carried out and the optimized parameters are calculated using DFT (B3LYP) method with 3-21G basis set for In2O3. A study of the electronic properties; absorption wavelengths, band gap energy, dipole moment, Kubo gap (HOMO and LUMO) and frontier molecular orbital energies, are performed by DFT method.

Abstract

Over the past few decades, light microscopy has become an important and widely used tool in forensic science research. It is a fast and accessible method, and is non-destructive, which is useful when dealing with precious and irreplaceable samples. Often used in forensic laboratories, specialists use this technique as a first-line analysis for research and investigation, prior to subsequent techniques. In forensic research, other specialized forms of microscopy such as comparison microscopy and polarized light microscopy are also utilized. The forensic science research team at the Abertay University in Scotland has used Olympus opto-digital light microscopes to expedite a number of research projects. Opto-digital technology integrates the latest in digital and optical technologies and allows fast and comprehensive analysis and measurement in materials science applications. The Olympus DSX range covers measurement, investigation, and reporting, and allows intuitive operation. This means in-depth microscopy knowledge is no longer required for precise inspection.

Influence of Inter-Electrode Distance, Gas Mixing, Magnetic Field and Cathode Material on Breakdown Voltage of Lab-Made DC Magnetron Sputtering Device

Abstract

In this paper, the effect of inter-electrode distance, gas mixing, magnetic field and cathode materials on breakdown voltage in DC glow discharge of argon and argon-oxygen plasma is presented. The results showed an increased breakdown voltage when inter-electrode distance and oxygen percentage in (Ar∕O2) gas mixture increased. At lower pressure, the breakdown voltage decreases by increasing the magnetic field, while at higher pressure, the breakdown voltage becomes less sensitive to the magnetic field. Moreover, the lower breakdown voltages are associated with smaller work function of the cathode material.

Analysing Asbestos using High-Speed X-Ray Diffraction

Abstract

Asbestos is a naturally occurring silicate material and is often used as a building material for its excellent resistance to acid and heat. However, the material is known to cause adverse health effects and hence has progressively been banned. Following the revision of Japan's Ordinance on Prevention of Asbestos Hazards and Industrial Safety and Health Act enforcement ordinance in 2006, the proposed limit value for asbestos content was made more rigorous. As a result, in any product, the present content by weight of asbestos is stipulated to be below 0.1%. This article shows an example of rapid quantitative analysis of the chrysotile (a type of asbestos) using the new high-speed, wide-range detector OneSight.

Abstract

Paillier cryptography has its security based on large key sizes. Such requirement causes problems at implementation stage; an overflow may be caused when using a large prime numbers; especially when computing exponentiation and the modules of division. In this paper two ways were suggested to overcome such problems and to provide reliable secure Paillier cryptography system. Paillier cryptosystem were implemented with these suggestions using visual Basic programming. The results of the suggested implementation showed that Paillier cryptosystem was executed with relatively long key size and with encryption time shorter than decryption time.
