Title: Statistical Analysis of the Mixed Accelerated Life Test for the Type II Progressively Censored Sample Authors: Qin, Xiao-qiong; Shi, Yi-min; Gao, Ni; Hu, Jun-mei Abstract: This paper studied statistical analysis of a new kind of accelerated life testing which combined progressively and constantly life test. The point estimations of the parameters in Exponential distribution and acceleration equation are obtained based on type II progressively censored data. Furthermore, we give the interval estimations of the parameters by Bootstrap sample. Besides, the estimations of the failure rate, the reliability functions and mean life are given at normal stress level, as well as the approximated unbiased estimations of failure rate and mean life. In the end, an illustrative numerical example is examined by means of the Monte-Carlo simulation Description: 23-32

Title: Supramolecular Hydrogels Authors: Maity, Gopal Chandra Abstract: In recent years there has been a considerable interest in developing new types of low molecular mass hydrogels because of their potential technological applications. Several classes of low molecular weight compounds form stable and efficient gels with aqueous solvents at low concentrations. Gels can be studies by several techniques. Description: 173-186

Title: Design of a Phase Detector with Improved Performance Authors: Chakraborty, B; Pal, R.R Abstract: This paper presents a new type of bipolar analog Phase Detector (PD) using a high speed low voltage Emitter Coupled Logic (ECL) inverters, where positive feedback has been introduced to increase the operating range. Introduction of positive feedback has also reduced the supply voltage requirement. The same technique has been introduced in a NMOS Gilbert phase detector and similar results were obtained. The minimum supply voltage required for both these circuits were 2.1 volts. Description: 213-220

Title: Surface Plasmon Excitation in 2p3/2 X-ray Photoemission Satellites of Nickel Dihalides Authors: Srivastava, Sanjay Kumar; Bahadur, Amar Abstract: The origin of 2p3/2 satellites of Nickel dihalides have been explained using plasmon theory with new approach by considering relative contribution of extrinsic and intrinsic effects. The present calculated values for the energy separation and relative intensity agree well with the experimentally observed values. Our calculation shows that satellites are due to surface plasmon excitation. We have also reviewed the existing calculations and experimental measurements Description: 201-206
