Determination of Natural Frequency of Aerofoil Section Blades Using Finite Element Approach, Study of Effect of Aspect Ratio and Thickness on Natural Frequency

Abstract: In this paper an attempt has been made to calculate the natural frequencies of aerofoil section blades using the finite element method. The effect of varying the aspect ratio and thickness on the frequencies has also been studied. It is observed that by increasing the value of aspect ratio, the natural frequency in all the modes is increased. It is also concluded that, there is some optimum value of thickness at which the natural frequencies in different modes of vibration are minimum.

Indigenous Technique of Biochar Production and Effect of Biochar Application on the Geotechnical Properties of the Expansive Soils

Abstract: Expansive soils have been a source of risk to human beings as they causes huge economic loss including damage to buildings, roads and other civil infrastructures because of their low compressive strength and excessive settlement characteristics. One of the available options is to replace such soils before starting any civil engineering construction but looking to huge costs involved in replacement; it is generally not practiced nowadays. Another viable alternative is to improve the engineering properties of such soils through stabilization. The conventional methods of stabilization make use of cement, lime, fly ash, rice husk ash, sawdust ash and other fibrous materials. Researchers are always finding alternative methods of soil stabilization making use of modern scientific techniques which are cost-effective as well as eco-friendly in nature. The present study focuses on producing biochar from agricultural crop residues and making use of it for stabilizing the expansive soils. India being an agricultural country produces a large volume of crop residues which creates an environmental problem in absence of proper management and disposal system. Indian farmers generally practice stubble burning in their fields which causes emission of greenhouse gases in the atmosphere and at the same time damage to the soil biota. A simple indigenous method of producing biochar has been developed wherein the crop residues are converted into biochar which is further applied to expansive soils as a stabilizing agent to improve the physical, chemical and engineering properties. In India, not much work has been carried out hitherto on biochar application to soils. The process of making biochar and the effects of utilizing biochar on the properties of expansive soil have been presented in this paper, which will prove useful for the Indian context where large quantities of agricultural wastes are produced that create environmental air pollution when burnt openly in fields.

Healthcare Services Customers’ ICT-Related Expectations and Experiences

Abstract: In the course of recent years, Indian healthcare services specialists and providers have given importance to consumer loyalty and satisfaction along with the quality for treatment. Nevertheless, there is little evidence from Indian analysts and researchers working at medicinal services customers as well as in different areas of service sector. The studies which have been conducted form either a fragmentary conglomeration or remain explicit and specific. Subsequently, it is not clear what the researchers have precisely learnt about customer of human services and what areas need further investigation. Thus, the motivation behind the present investigation is to build up a broad and deliberate study on healthcare customers, to comprehend the connection between them and the necessities from service providers. The paper further recognizes the components related with ICT for healthcare services and factors influencing the customers’ satisfaction levels. It deals with changing customers’ expectations and experiences, with especial reference to healthcare services, process, correspondence and communication, with the progression of ICT in the recent years. It assists the healthcare service providers to become customer-focused by embracing recent ICT services thereby helping them in providing better healthcare.

Atomic force microscopy studies of homoepitaxial GaN layers grown on GaN template by laser MBE

Abstract: We have grown homoepitaxial GaN films on metal organic chemical vapor deposition (MOCVD) grown 3.5 µm thick GaN on sapphire (0001) substrate (GaN template) using an ultra-high vacuum (UHV) laser assisted molecular beam epitaxy (LMBE) system. The GaN films were grown by laser ablating a polycrystalline solid GaN target in the presence of active r.f. nitrogen plasma. The influence of laser repetition rates (10-30 Hz) on the surface morphology of homoepitaxial GaN layers have been studied using atomic force microscopy. It was found that GaN layer grown at 10 Hz shows a smooth surface with uniform grain size compared to the rough surface with irregular shape grains obtained at 30 Hz. The variation of surface roughness of the homoepitaxial GaN layer with and without wet chemical etching has been also studied and it was observed that the roughness of the film decreased after wet etching due to the curved structure/rough surface.

A re vie w stud y of lightweight proactive source routing protocol for MANETs

Abstract: Mobile Ad hoc systems have recognized expanding mindfulness in the present couple of years. As of late, systems administration of unattended detecting gadgets has expected noteworthy consideration from the exploration group. In this paper we exhibit a survey investigation of lightweight proactive source steering conventions of Mobile Ad hoc systems. In this paper we likewise audit and analyze the proposed Extended Proactive Source Routing convention to minimize adjustment of the tree of every current hub in a way to get most proficiency from the framework which is the examination work done under the undertaking “EPSR: An Enhanced Lightweight Proactive Source Routing Protocol For Mobile Ad Hoc Networks”.
