A review of optimization on turning process parameters for surface roughness in dry and wet condition of AISI 1045 steel using Taguchi method

The challenge of recent machining industries is reduced lead time and increase production rate in order to maintain their competitiveness. The mechanical manufacturing industries are regularly challenged for achieving higher productivity and high-quality products in order to remain competitive. The desired shape, size and finished ferrous and non- ferrous materials are conventionally produced by turning the preformed blanks with the help of cutting tools that moved past the workpiece in a machine tool. Among various cutting processes, turning process is one of the most fundamental and most applied metal removal operations in a real manufacturing environment. This literature review compiles different work presented on optimization of process parameters and concludes the most significant cutting parameters and most frequently used optimization techniques for improving surface finish. The cutting parameters like Cutting speed, Feed rate and Depth of cut are taken into consideration.

Steel structures, pushover analysis

Steel structure has an important role in construction Industry In last decades. To perform well under seismic loads it is necessary to design a structure. According to the provisions of the current Indian code (IS 800 -2007) the seismic performance of a multi-story steel structure building has designed. By introducing Steel bracings in the structural system the shear capacity of the structure can be increased to arrange Steel bracings such as D, K, and V type eccentric bracings there are “n” numbers of solutions for various types of eccentric bracings as per the IS 800- 2007 a typical six-story steel structure building is generated. In the present study D, K, and V types of eccentric bracings are taken into consideration. Through nonlinear static analysis performance of each structure is studied.

Self-supported steel chimney analysis as per Indian standard

Most of the industrial steel chimneys are round cross-sections with column structures. Because of its frame behavior under lateral dynamic loading Geometry of a self-supporting steel chimney shows an important role. It is primarily responsible for the stiffness parameters of the chimney this is because of geometry. However, basic dimensions of industrial self-supporting steel chimney are generally derived from the associated environmental conditions, such as height, diameter at the exit, etc. Design code (IS-6533: 1989 Part 2) imposes several criteria on the geometry (top-to-base diameter ratio and height-to base diameter ratio) of steel chimneys to ensure the desired failure mode. To justify the code criteria with regard to basic dimensions of industrial steel chimney is the objective of the present study.

Fragility curves construction for an RC frame

The Seismic fragility curve is mainly applied to evaluate the planning of pre-earthquake disaster and recovery from post-earthquake. It provides the conditional probability of structural response to earthquake loads as a function of ground motion intensity. The traditional methods of generating fragility curves include a large number of computational models that represents the analysis of earthquake time history and inherent variation in the properties of materials of a particular building type. There are several Response surface methods available in which HDMR i.e. High Dimensional Model Representation which can express the input-output relation of complex computational models. This input-output relation can minimize the procedures of the expensive computations in problems like development of fragility curve. This technique was first applied by Unnikrishnan et al. (2012) in fragility evaluations and he demonstrated its computational efficacy compared to Monte Carlo method which is computationally intense. In this study, an HDMR response surface method is used to develop the fragility curve of an RC Frame. There are many simplified approaches which are quite easy on computational terms for fragility development of curve. Cornell et al (2002) offered such method that assumes a law model between the earthquake’s intensity and damage parameters. The study showcases the Fragility Curves assessment by using HDMR and its computational efficacy with reference to one of the methods used by Cornell et al (2002).

Robotic coating by using the doped nanoparticles with the help of copper and zinc nanoparticles

Nowadays nanoparticles play a major role in doing the research work and our intention is to develop the Robots by using the copper and it can develop major intentions to give a more potential to develop major things. By doing this work we can develop the Robots in major intentions to give more life in the extension of signaling and memory by using the coating of a material. The major intention is to develop an analysis of a Robot. nanoparticles solved and improved their role in various applications. These nanoparticles are successfully prepared by co-precipitation method. These are mostly used to characterize the microstructure and morphology at various instances.

Assessing forest degradation and analysis of future scenarios using GIS and remote sensing

The study entails detecting forest degradation and modeling future scenario using GIS and remote sensing, in Elgeyo/Marakwet County, a case study of Embobut forest, it is evident that forests have been managed for several years in the world, but in most cases especially in the developing world, various regimes have tried to come up with institutional to guide forest management with no much success, in many countries, there is no regular monitoring system that collects information about the situation of the forests and trends of the distribution. This makes it difficult to quantify the status of the existing forest cover. We used high-resolution satellite imagery as well as GIS and remote sensing software (ArcGIS and ENVI) with mathematical models to project the forest status, apart from satellite images there will be a ground truthing using Global positioning system (GPS) as data collection tool to as well as use of Auxiliary data; which will include Socioeconomic and data for the years 1980, 1990, 2000 and 2010. Policy implications especially with the enactment of Kenya forest act, 2005 was examined. recorded positive changes hence increased in size while all other forest classes decreased in size. The study found out that the total forest loss was 7,172.31 hectares, this represents a loss of 28 percent of the total forested area that existed in 1986 which corresponds to an annual forest loss of 286.892 hectares. According to this study, as population increased the rate of deforestation also increased. The future scenarios from the studies were based on a fixed annual deforestation rate and a conclusion is made that Bare land & rocky and water bodies classes increased in area while Mixed Podocarpus latifolius, Juniperus-Nuxia-Podocarpus factus, Tree ferns Cyathea manniana & Bamboo, Acacia abyssica & Scrubby grassland classes decreased in size. As Population grew forestry loss increased, between 1986 and 2011, the total forest loss was 7,172.31 hectares. Future Scenario found that with the same trend, there will be no forest remaining natural forest block by the year 2038 in the study area.
