Cosmic rays play an important role in our daily lives and can be used in various fields of educational research, especially in physics and astrophysics. However, the detection of cosmic rays is affected by many factors, and atmospheric water vapour pressure was recently suspected to be an important factor. Princess Sirindhorn Neutron Monitor (PSNM) is a cosmic ray detector in Chiangmai, and...

SnO$_2$ is an oxide semiconductor with wide band gap, good transparency, and high thermal and chemical resistances. As-grown SnO$_2$ usually exhibits $\textit{n}$-type conductivity with high carrier concentrations, which is an obstacle to make it $\textit{p}$-type. Consequently, applications of SnO$_2$ for optoelectronics are limited. Group-III elements, such as Al, Ga, and In, are...

Detailed infrared (IR) absorption spectroscopy of O$_2$-related defects in zincblend-CdTe and wurtzite-CdSe were reported by Lavrov *et al* [Phys. Rev. B **84**, 233201 (2011), AIP conf. Proc. **1583**, 169 (2014)]. They clearly showed based on their experimental work that the IR absorption bands at 1096.8 and 1108.4 cm$^{-1}$ in CdTe samples are associated with the vibrational modes of...

A Higher operating temperature increases a risk of mainboard in computer malfunction. In this work, the heat transfer and thermal distribution on a mainboard were investigated based on finite element analysis. We proposed boundary conditions and parameters at least to be defined. The results of simulation were compared with the actual results measured by the thermal imager. The comparison...

The electronic band structure of graphene was calculated using the full-potential linearized muffin-tin orbital (FP-LMTO) method. Its resonant inelastic x-ray scattering (RIXS) spectra at various x-ray excitation energies were calculated based on Kramers-Heisenberg equation. It is found that the RIXS spectra show distinct dispersive features and are interpreted as being due to the...

This study aimed to investigate thermodynamic properties of a rubber balloon including hysteresis and cooling effect of a deflated balloon. Firstly, pressure inside a balloon was measured using a Vernier pressure sensor and plotted as a function of the balloon averaged radius. Well-known mathematical models of inflated balloon including Mooney-Rivlin, Ogden and Gent-Gent models were used to...
