The use of titanium alloys is increasing rapidly nowadays. Simultaneously the requirement for machining of titanium alloys is also increasing. The present research work deal with the optimization of process parameters such as spindle speed, feed rate, depth of cut, MRR and surface roughness value for titanium alloy by using Advanced cutting Tools. Hence the present study uses titanium Grade 12 as work piece material and CBN and carbide as tool material and focusses on the optimum value of material removal rate and surface roughness. In this paper, Taguchi Method has been used to identify the optimal combination of influential factors in the milling process. Milling experiment has been performed on titanium Grade 12 material, according to Taguchi orthogonal array (L9) for various combinations of controllable parameters viz. speed, feed and depth of cut. The surface roughness (Ra) is measured and recorded for each experimental run and analyzed using Taguchi S/N ratios and the optimum controllable parameter combination is identified.

Most of the population of world is being concentrated in the metropolitan cities. Since the land areas of metropolitan cities are scarce with the high number of population, to counteract this problem, the structures which are being used as both commercial and residential purposes must grow vertically instead of growing horizontally. This vertical growth must be implemented to counteract the recurring growth of the population in most of the parts in the world. In this study, the vertical growth is referred to a high-rise building, and a comparative analysis of dynamic loads are carried out on these high-rise structures using various International Standard Codes (American, European and Indian), with the inclusive of recently developed IS 1893:2016.

Precipitation falling on the soil wets down and it starts penetrating into the soil. Water stores to the formal level the soil moisture deficiency excess moving down by the gravity force through percolation or seepage to build up the water table. The water is driven into the porous soil by force of gravity. First the water wets soil grain sand then the extra water moves down due to gravitational force. The rate at which a soil absorbing the water in a given time is called infiltration rate and it depends on soil characteristics such as hydraulic conductivity, soil structure, vegetation cover. The infiltration plays an important role in generation of runoff volume, if infiltration rate of given soil is less than intensity of rainfall then it results in either accumulation of water on soil surface or in runoff. The different soil conditions affect the soil infiltration rate. Compacted soils due to movement of agricultural machines have a low infiltration rate which is prone to runoff generation. Infiltration will be maximum at the beginning and it decays exponentially and gets a constant value. There will be a decrease in infiltration rate day by day due to the saturation of the soil where as on the first day the infiltration rate will be more because soil will be dry in condition. Infiltration of water into the soil has important impact in the overall functioning of the variable land based activities. Two factors can greatly undermine availability of water for crops which is impervious layer and ground water table. The former might be due to excess infiltration which mostly a function of soil characteristic get through the later may be largely due to the deposit of clay that can create crust below the surface. The study of infiltration comes in many hydrological problems like runoff estimation, soil moisture budgeting and for planning of irrigation. Infiltration has an important place in the hydrological cycle.

Smartphone users have their own unique behavioral characteristics when performing touch operations. In this paper we have developed in which user’s Hand Waving Pattern is recorded and stored as user’s Pattern. In case of emergency, if victim is in peril situation, the victim can protect themselves by using their mobile pattern. The sensor is used to analyze the body behavior of the victim and if pulse rate increases automatically, it is used to trace the victim location by using GPS. The camera and photo are initiated to fetch exact location of the victim. Voice of the victim under the emergency is also recorded and uploaded to the server. Both GPS and audio link of the victim are sent as SMS alert to both nearest police station and the registered custodian / relative.

Pages: 39 - 46
There has been a considerable increase in the construction of tall buildings both residential and commercial and the modern trend is towards more tall and slender structures. Thus, the effects of lateral loads like wind loads, earthquake loads and blast forces are attaining increasing importance. Shear wall system is one of the most commonly used lateral load resisting system in high rise buildings. Shear wall has high in plane stiffness and strength which can be used to simultaneously resist large horizontal loads and support gravity loads, which significantly reduces lateral sway of the building and thereby reduces damage to structure and its contents. When shear walls are situated in advantageous positions in the building, they can form an efficient lateral force resisting system by reducing lateral displacements under earthquake loads. Therefore, it is very necessary to determine effective, efficient and ideal location of shear wall.

India, with vast agricultural lands has different crops ranging from paddy to tomato. But few crops are destroyed due to animal menace and hence a protection is required to save the crops from animal. For this project, an attempt is made to save these crops from such menaces by using solar fencing. In this, a triple lift additional circuit is used instead of transformer and rectifier bridge to produce high voltage with low current in order to safe-guard the animals to a larger extent so that they experiences high voltage but low current shock for a very short time there by saving their life.

Any point inside the mountain is subjected to stresses from all the directions. Excavation of any cavity like an underground power house or boring of a tunnel, results in the release and readjustment of three dimensional stresses around the cavity. This results in displacements/ deformations which are time dependent. Extensometer is used to measure deformation of a section of rock mass and adjacent surrounding strata with the help of anchors at different depths. The depth of anchor varies with the type of rock strata and the location of the fixed point with respect to which the deformations are to be measured. This paper deals with the instrumentation for deformation of rock mass using extensometers in underground powerhouse of Sardar Sarovar Project, Gujarat for long term monitoring along with results and conclusion.

To determine the impact of different soils and seismic zones on different heights of framed structures. In high rise building we should concern about all the forces that act on a building, its own weight as well as the lateral forces. In this work, total 48 models are analyzed. To determine the impact of different soil and seismic zones on varying height of framed structure, this work is carried out. Three different soils types are taken as soft, medium and hard. Stories i.e., G+4,G+5, G+6 & G+7 are taken of heights 15m, 18m, 21m & 24m respectively are considered and analyzed for seismic zones II,III,IV & V. SMRF(Special Moment resisting Frame) & IS 1893-2002/2005 are used in STAAD PRO.(V8i) series 4 to analyze all models. This work consist of the analysis of RC framed structure for Maximum Beam End Force (SHEAR-Y in Beam-KN) & Maximum Beam End Force (MOMENT-Z in Beam –KNm. This is to figure out the variation of Maximum Shear force & Maximum Bending moment for all types of heights and to find out the most severe models among all. Height can also be extended beyond 24m and plan size can also be changed for further research point of view.
