Automatic web service composition is not a trivial problem, especially when the number of services is high and there are different control structures to handle the execution flow. Some approaches, treat the composition problem as a planning problem. In general, these approaches have important drawbacks such as high complexity, high computational cost and inability to maximize parallel execution of web services. Other approaches consider the problem as a search problem, where a search algorithm is applied over a graph or a tree in order to find a minimal composition. These proposals are simpler and more effective than the other approaches, and also many of them can exploit parallel execution of web services but it does not provide optimal result.

Current trends in construction industry demands taller and lighter structures, which are also more flexible and having quite low damping value. Now-a-days several techniques are available to minimize the vibration of the structure, out of the several techniques available for vibration control; concept of using TMD is a newer one. This study was made to study the effectiveness of using TMD for controlling vibration of structure. The numerical stimulations are performed to study the structure with and without TMD. A twelve storied building with rectangular shape is considered for analysis. Analysis is done by FE software SAP2000 by using direct integration approach. TMDs with percentage masses 2%, 3%, 4%, 5% are considered. Three different recorded time histories of past EQ are used for the analysis. Namely 1940 EL-Centro EQ, Northridge EQ, and Taft EQ. comparison is done between the buildings with TMD and without TMD. From the study it was found that, TMD can be effectively used for vibration control of structure. TMD was more effective when damping ratio is less. Gradually increase in the mass ratio of the TMD result in gradually decrement in the displacement response of the structure.

The pressure on farm sector has been increasing due to multiple reasons: lower yield, fragmentation of land holdings, poor irrigation, depletion of ground water, inadequate extension services/ supply of inputs, poor post-harvest management, lack of value addition at the producer’s level and a long supply chain involving a number of intermediaries. There is a strong need to assist the farmers to increase productivity to move up the value chain in simulating the farm economy and employment demand. Interventions such as, establishing market linkages, providing access to micro planning, creation of irrigation facilities/rain water harvesting structures, efficient water use through micro-irrigation, managing natural resources efficiently etc. can generate better farm as well as non-farm sector yields and change the rural landscape in better way. The agriculture sector is the predominant consumer of water. Almost 70% of all available freshwater is used for agriculture across the world. There is long and growing list of measures that can increase agricultural water productivity. Drip irrigation ranks near the top of measures and can achieve efficiencies as high as 95 percent, compared with 50-70 percent for more conventional flood or furrow irrigation. Micro irrigation reduces the virtual water requirement of the agricultural products thus improving water use efficiency. Government of Gujarat has formed the Gujarat Green Revolution Company Limited (jointly promoted by GSFC, GNFC and GAIC) act as nodal agency and implement uniform scheme for Micro Irrigation System in the State.

Drying is probably one of the oldest methods of food preservation. The tray dryer is widely used in a variety of applications because of its simple design and capability to dry products at high volume. A drying system incorporating the HP (heat pump) was designed and constructed, along with necessary instrumentation to gather data on the properties of process air as well as real-time weight of the material being dried (mango slices). Drying was carried out in three different temperatures 50, 55 and 600C. The design of the system allowed for conducting drying with recirculation of air as well as use of backup electrical heaters. Comparisons of all three cases were made and it was found that drying time decreases with increase in temperature. Also drying rate increases with temperature. In terms of energy consumption, the process of HP assisted drying is more expensive, but drying time justifies its cost.

The main problem encountered in steel reinforced concrete structures is the corrosion of the steel bars which eventually results in the failure and disintegration of the structure. Fiber-reinforced polymer (FRP) rebar has been considered as an alternative for this since corrosion is a material problem. The purpose of this research was to investigate flexural behaviour of GFRP and steel reinforced beams. The beam sections used in this research is of size 150 x 200 mm and of 1600 mm length. Flexural strength was determined and crack pattern studies were carried out.

The use of fiber reinforced polymer in the repair and strengthening of reinforced concrete members is currently being discussed worldwide. Fiber reinforced polymer application (FRP) is a very effective way to repair and strengthen structures that have become weak due to life span and design defects. FRP repair systems provide an economically viable alternative to traditional material and repair system. Experimental investigations on the flexural behavior of RC beams strengthened using continuous fiber reinforced polymer (FRP) sheets were carried out. Externally reinforced concrete beam epoxy-bonded GFRP (Glass fiber reinforced polymer) sheets are tested to failure using symmetrical two point concentrated static loading system. Three sets of beams were casted for this experimental test program and tests were carried out by varying the number of fiber layers.

Ethernet for Data transfer in Computer Networks is ubiquitous. However some recent advancements in DC Powering have enabled transporting power and data simultaneously, over the same Ethernet cables. This technique is known as Power over Ethernet (PoE). However there are few challenges though, the first and the foremost being that of operational safety of the devices which are not PoE compliant. It needs to be noted that IEEE 802.3af standard specifies a 15W of PoE power at 48Volts DC which if connected to an incompatible device, may end up damaging it, permanently. Hence it is important that a PoE Equipment is tested and confirmed that it allows for safe and reliable operation of non-compliant devices. Failure to confirm this may have a catastrophic impact on the network that could range from a network crash to an imminent fire hazard. This paper discusses important tests which need be performed to ascertain that the PoE equipment being connected in the network will allow for safe and reliable operation of incompatible or legacy network devices. A LTSPICE simulated PoE network has been considered to carry out these various tests as well as for the verification of the safety features incorporated in the PSE-PD combination and its compliance to IEEE 802.3af standard. The observations and results are tabulated and conclusions are drawn.

Sun powered power is utilized as just the wellspring of energy to control the general framework. Sensors are set on the paddy field and these sensors constantly sense the water substance and give the message to the agriculturist. Without going to the paddy fields, ranchers can get the data about the Moisture substance and agriculturist can control the pump set by communicating something specific from his PDA even from a remote place where system is accessible. Be that as it may, if the Moisture level scopes to the low level the engine will naturally begin without insinuation to agriculturist and to guarantee the correct water level in the site. Toward the finish of this paper, a total equipment usage of this proposed robotized water system framework will be introduced.

Cooling of heated plates finds applications in various fields like cooling of electronic devices. Commonly used method for cooling of electronic devices such as computers is by using fan. With the advent of electronic industry cooling requirements from compact surfaces become the primary focus of research. Jet impingement cooling mechanism with pulsating impinging jet array has proved to be one of the most efficient heat transfer mechanism for cooling applications. The idea of impingement heat transfer is to obtain the higher heat transfer coefficients from a given surface with limited area by means of the high velocity of the jets. Thus, a study is required to optimize the different aspects of the mechanism so as to achieve maximum heat transfer. In this project combined steady and pulsating jet array is used for heat transfer. Various arrangements of jets are considered. Also analysis of different frequencies of jets is done. The best combination for maximum and uniform heat transfer is to be found out. The study is being conducted with the help of CFD simulation package Ansys Fluent.

In the present era where energy demands are growing everyday it has become very important to capture every available energy from the hot source and utilize it for the process with minimum wastage. With this view, the combined serial two shell pass shell and tube heat exchanger (CSTSP) concept had been put forward and simulated using Fluent. Though the novel model of the heat exchanger has a higher heat transfer rate than the conventionally used segmental baffle heat exchanger but it poses a limitation with a higher pressure drop. This paper analyses the CSTSP model by incorporating certain changes in the geometry to try out two test cases namely CSTSP-B & CSTSP-C. Numerical analysis is performed on these models and their performance is compared with the original model. This study aims to put forward more insight on the performance of the CSTSP model heat exchanger to help researchers in future to optimize the geometric model and obtain a balance between heat transfer and pressure drop.

Time, safety and economy constitute the three main factors in a construction project, of which time plays a significant role in construction. Delay in any task or operation is a time overrun which influences the completion of the work. A cost overrun, also known as a cost increase, underrated or budget overrun, involves unexpected costs incurred in excess of budgeted amounts due to an underestimation of the actual cost during budgeting. Accident don’t just happen, they are caused by unsafe acts, unsafe conditions or both. Most accidents result from a combination of contributing causes and one or more unsafe acts and unsafe condition. This study was based on a list of construction problems, causes retrieved from literature reviews. The feedback of construction experts was obtained through interviews. Subsequently, a questionnaire survey was prepared. The questionnaire was distributed to construction experts who represent owners, consultants, and contractor’s organizations. A case study was analyzed and compared with the most important problems causes in the research. Recommendations was made in order to reduce the problems in constructions.

The drying or dehydration is the controlled heating of food products to evaporate quantified amount of moisture that is originally present in it. Drying of food products is essential to enhance the shelf life of the product without quality losses over an extended period of time. It is an energy intensive process. The fluidized bed dryer with heat pump is one of the efficient method to reduce the energy. This project presents the design of fluidized bed dryer with heat pump. Drying was carried out in three different temperatures 50, 55 and 60°C. Comparisons of all three cases were made and it was found that inlet air temperature is the main parameter that affect the drying time. The drying time is decreases as the inlet temperature increases.

A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. Now a days, bridge deck section of Box shapes are used widely. Most of the bridges constructed are of Box girders. Method of post-tensioning in the construction of bridges is very common today. Most of the bridges are of prestressed types (mostly post-tensioned). In this work, an attempt was made to comparative study the different shapes of PSC Box Girder Multi Cell Bridge using CSI Bridge (V-2017). Loading of IRC Class-A is applied and analysis is done using IRC 112 (2011).

A case study was conducted to find out the groundwater potential zones in Virudhunagar district, Tamil Nadu, India with an aerial extent of 4243.23 sq.kms. The thematic maps such as geology, geomorphology, soil hydrological group, land use / land cover and drainage map were prepared for the study area. Worldwide rapid growth of population, industries and agricultural activities brought about a steep increase in water demands which have to be met from available surface and ground water resources. Ground water has gained prime importance during the past decades. This has been mainly on account of its dependability throughout the year and in particular during the periods of scanty rainfall and drought condition. The Geospatial technology has proved very efficient in assessing the ground water potential of any area. This paper aims Delineating the groundwater potential zones of a location by utilizing the existing data obtained through geological and soil surveys. The capabilities of GIS and Remote sensing has been harnessed to map the areas with potential ground water sources which could be used to easily identify and recharge the areas for future uses. This GIS based output result was validated by conducting field survey by randomly selecting wells in different villages using GPS instruments. The coordinates of each well location were obtained by GPS and plotted in the GIS platform and it was clearly shown that the well coordinates were exactly seated with the classified zones.

Crumb rubber is a material produced by shredding and commutating used tires. Waste tire dumping, disposal of these materials or burning these tires cause serious health and environmental problems. On the other side the traffic intensity also increasing day by day and thus bearing capacities also increased the long term goal of the work is to find a means to dispose of the crumb rubber in concrete and still provide a final product with good engineering properties. Due to the depletion of natural sand it is required to use other material than sand being used as the fine aggregate in concrete. The innovative use of the crumb rubber in concrete formulations as a sand replacement in range of 0%, 2.5%,5%,7.5% and 10 % by weight for M-25 grade cement (OPC). It will include an experimental review on the effects of CRM on compressive test and flexure test.
