Abstract

The triaxial dynamics of the quadrupole-deformed rotor model of both the rigid and the irrotational type have been investigated in detail. The results indicate that level patterns and E2 transitional characters of the two types of the model can be matched with each other to the leading order of the deformation parameter $\beta$. Especially, it is found that the dynamical structure of the irrotational type with most triaxial deformation ($\gamma=30^\circ$) is equivalent to that of the rigid type with oblate deformation ($\gamma=60^\circ$), and the associated spectrum can be classified into the standard rotational bands obeying the rotational $L(L+1)$-law or regrouped into a new ground- and $\gamma$-band with odd-even staggering in the new $\gamma$-band commonly recognized as a signature of the triaxiality. The differences between the two types of the model in this case are emphasized especially on the E2 transitional characters., Comment: 8 pages, 5 figures

Abstract

This paper considers cooperative amplify-and-forwards (AF) two-way relay networks (TWRNs) with opportunistic relay selection (ORS) in two-wave with diffuse power (TWDP) fading channels. To investigate the system performance, we first derive an easy-to-computer approximated expression for the exact outage probability to reduce computational cost. Furthermore, we presented compact expressions for the asymptotic outage probability and asymptotic symbol error rate, which characterizes two factors governing the network performance at high signal-to-noise ratio (SNR) in terms of diversity order and coding gain. Additionally, based on the asymptotic outage probability, we determine the optimal power allocation solution between the relay and the sources to minimize the overall outage probability under the assumption that both the sources have identical transmit power. The correctness of the analysis is validated through Monte Carlo simulations. Our derived results can be applied to general operating scenarios with distinct TWDP fading parameters which encompass Rayleigh and Rician fading as special cases and arbitrary number of relays.

Abstract

The temperature distribution of the integrated gas sensor array is discussed. Since it is difficult to measure the surface temperature on an integrated gas sensor chip experimentally, the finite element analysis (FEA) technique is used in our simulation design of the microstructure gas sensor array. First, the model is derived from the array's exact structure and physical features. Second, we discussed the temperature distribution under steady state of the integrated gas sensor array according to the variances of material properties and the array's structure. Finally, we designed and manufactured a novel integrated gas sensor array based on FEA. The experimental results show that the above-mentioned study is feasible and satisfactory.
