Blast furnace (BF) is a giant countercurrent reactor and heat exchanger, and is the first step towards the production of the steel. It is one of the most complex industrial reactor and is impossible to model mathematically. The operation and control of an industrial blast furnace is a serious problem, hence to overcome this we are using Artificial Neural Network (ANN). It is very important to predict the various temperatures i.e., Raceaway Adiabatic Flame Temperature (RAFT), Stack temperature and uptake temperature. Optimizing these temperature distribution would lead to considerable savings of input material of blast furnace. Productivity as well as quality can be improved by knowing these parameters in advance. In this paper, we are using the multi input multi output (MIMO) artificial neural network. By this we have to optimize overall efficiency, minimize operational cost, and reduce fuel consumption which leads to improve productivity. The input parameters used are Oxygen enrichment, Blast volume, Blast pressure, Top gas pressure, Hot Blast temperature, steam injection rate, cold blast flow, cold blast temperature and Pulverized coal injection rate. For prediction and optimization back propagated, feed forward artificial neural network is applied. All the input data were collected from the Vizag steel plant (VSP) during the period of 5 months.

The Heat treatment and carburization has been recognized by certain methods for improving the different properties of metals and combinations. In the present examination the mechanical and wear practices of gentle steels carburized at various temperature scope of 850, 900 and 9500C have been contemplated and it is discovered that the basic warmth treatment significantly improves the hardness, elasticity and wear opposition of the mellow steels. The point has been to look at the impacts of these distinctive temperature of carburization s and conditions on the mechanical and wear properties of the carburized gentle steels. For above reason initially the mellow steels are carburized under the diverse temperature go as expressed above and afterward it is tempered at 2000 C for thirty minutes after this the carburized and tempered gentle steels are oppressed for various sort of test, for example, rough wear test, hardness test, elastic test and the durability test. The aftereffects of these test demonstrates that the procedure of carburization significantly improves the mechanical and wear properties like hardness, elasticity and wear obstruction and these properties increments with increment in the temperature of carburization yet separated from this the durability property diminishes and it is further reductions with increment in temperature of carburization . The trial results likewise demonstrates that the mellow steels carburized under various temperature extend as expressed above, with in which the gentle steels carburized at the temperature of 9500C gives the best outcomes for the various types of mechanical and wear properties on the grounds that at this temperature it gives most astounding elasticity, hardness and wear opposition, so it must be favored for the required applications.

The floating column is a vertical member which rest on a beam but does not transfer the load directly to the foundation. The floating column acts as a point load on the beam and this beam transfers the load to the columns below it. Floating column can be termed as a column resting on a beam instead for distributing load directly to the foundation. It acts as a point load on a beam which is further distributed to column attached to beam. In this review paper we are reviewing the past researches related to structure with long spans and structures with floating columns.

Delhi region is facing the problem of scarcity of water throughout the year. To check this problem, various efforts have been made. Rainwater harvesting is such an effort which can be used to address the problem of shortage of water effectively. This can be done by constructing check Dams, Percolation Tank, Bore well, Dug well, Dug cum bore well, Farm Pond, etc. In the present dissertation, Selection of suitable rainwater harvesting site are carried out with the help of GIS and remote sensing in Delhi region. In this study suitability of rainwater harvesting sites is carried out by GPS, Survey of India toposheets on scale of 1:250,000, SRTM data for creation of DEM and satellite imagery of LANDSAT ETM+ (30mt. spatial resolution). This study therefore focused on the development of suitability level for most important factor and parameters for identification of such sites. These factors include rainfall, soil texture, drainage, topography and land use / land cover and integration of these factors using weighted overlay analysis with the help of ArcGIS software provide suitable sites for rainwater harvesting. These sites are then classified into various suitability levels, namely, 1, 2, 3, 4 and 5, 5 suitability level is the most suitable region and 1 suitability level is the least suitable region for rainwater harvesting. By applying above process, the results shows that in Delhi region there are several suitable sites with highest suitability level which can be used for Rainwater harvesting. Hence, the conclusion of the study is that site suitability analysis for surface rainwater harvesting using GIS and remote sensing is the better technique for finding rainwater harvesting suitable site with quite appreciable accuracy.

Focusing on making an incentive for clients is an essential idea of Lean. Worth is not just a word to be characterized in Lean, yet additionally it is actually what the entire organization should go for and what is not characterized as worth ought to be decreased or evacuated. Thinking about this reason, value‐stream mapping as a device in Lean Production was followed in writings and help of most experience people for executing this instrument. Because of the way that most improvement proposals are tied in with arranging of process duration decrease, improve work-in-process, improve machine and diminish labor, so an exact and practical guide can make a solid stage for enhancements. In this way, the more precise the present express the more reachable advancements. By executing the worth stream mapping we effectively get the bottleneck procedure and thought for usage and examination the outcomes. So we can lessen the most extreme process duration from 12 sec to 9.0sec and decrease labor from 45 to20 per move. That is we get the greatest advantage by VSM which is increasingly other lean procedure. So future state gets the clearest view and further distinguished the open door for development.
