Facies analysis of fluvial deposits of the Proterozoic Sanjauli Formation in the Lesser Himalaya was combined with an architectural analysis. On this basis, a model was developed that may be applied to other fluvial systems as well, whether old or recent. The new model, which might be considered as an assemblage of previous models, explains lateral variations in architecture and facies but is not in all respects consistent with the standard fluvial models. The Sanjauli fluvial model is unique in that it deals with lateral facies variations due to shifts of the base-level along with fluctuations in accommodation space owing to changes in palaeoclimate.

Implementation of all-optical tristate Pauli X, Y and Z gates based on two-dimensional photonic crystal

Quality of strip is mainly characterized by mechanical property, dimensional tolerance, and surface appearance. Uniform mechanical property, desired tolerance, and high surface finish are essential to produce high end products. In case of mechanical property, while much of this can be achieved through sophisticated process control and good operational practice, needless to say that a good quality slab is an imperative for this. Thus, cleanliness, and internal soundness of slabs are some of the prerequisites. Danieli’s philosophy of Quality Strip Production involves through-process control and optimization of casting and rolling processes. The automation solutions for casting process such as Liquid Pool Control System, Dynamic Secondary Cooling, and Dynamic Soft Reduction provide slab with internal soundness, which is free from internal defect, segregation and give favourable grain structure through improved solidification. On the other hand, rolling solution such as Coil Quality Estimation ensures desired mechanical property and its uniformity over entire length of a strip in real-time processing in the rolling mill. An intergrated solution, therefore, is the key. Furthermore, Danieli is planning to integrate automation solutions for bulging control and Inclusion Control to present the inclusion map of the slab. Thus, the integration and control of automation solutions for casting and rolling provide the key for future products of superior quality.

Optoelectronics Letters 2024年第6期20卷 346-352页

作者： Snigdha Hazra Sourangshu mukhopadhyay Department of Physics The University of BurdwanBurdwan 713104India1

In this paper, we have designed and simulated all-optical tristate Pauli X, Y and Z gates using 2D photonic crystal. Simple line and point defects have been used to design the structure. The performance of the structure has been analyzed and investigated by plane wave expansion(PWE) and finite difference time domain(FDTD) methods. Different performance parameters, namely contrast ratio(CR), rise time, fall time, delay time, response time and bit rate, have been calculated. The main advantage of the proposed design is that all the Pauli gates have been realized from a single structure. Due to compact size, fast response time, good CR and high bit rate, the proposed structure can be highly useful for optical computing, data processing and optical integrated circuits.

The unsteady flow of a Casson fluid and heat transfer over a stretching surface in presence of suction/blowing are investigated. The transformed equations are solved numerically by using the shooting method. The exact solution corre- sponding to the momentum equation for the steady case is obtained. Fluid velocity initially decreases with the increase of unsteadiness parameter. Due to an increasing Casson parameter the velocity field is suppressed. Thermal radiation enhances the effective thermal diffusivity and the temperature rises.

A boundary layer analysis is presented for non-Newtonian fluid flow and heat transfer over a nonlinearly stretching surface. The Casson fluid model is used to characterize the non-Newtonian fluid behavior. By using suitable transformations, the governing partial differential equations corresponding to the momentum and energy equations are converted into non-linear ordinary differential equations. Numerical solutions of these equations are obtained with the shooting method. The effect of increasing Casson parameter is to suppress the velocity field. However the temperature is enhanced with the increasing Casson parameter.

An analysis of the heat transfer for a boundary layer forced convective flow past a moving permeable flat surface parallel to a moving fluid is presented. Prescribed surface temperature at the boundary is considered, A thermal radiation term in the energy equation is considered. The similarity solutions for the problem are obtained and the reduced ordinary differential equations are solved numerically. To support the validity of the numerical results, a comparison is made with the available results for some particular cases of this study. Dual solutions exist when the surface and the fluid move in the opposite directions.
