GREENHOUSE GAS DIFFUSIVE FLUX ASSESSMENT FROM FEWINDIAN RESERVOIRS[ ]


There is a growing interest and concern regarding Green House Gas (GHG) emissions as these is the major contributors of global warming. Carbon dioxide (CO2) and Methane (CH4) are two main GHGs which get emitted from both natural aquatic and terrestrial ecosystems as well as from anthropogenic activities. In natural aquatic system water storage is an important aspect for meeting the requirements of drinking water, food, and energy. However, development of such water bodies will impact the environment. Recent studies have shown that water bodies play a significant role as the sources of GHG emission, particularly in tropical climatic zones. One possible reason for this is the annual water temperature is much higher in tropical climates. This means that the rate of decomposition is faster leading to higher CO2 and CH4 flux in the water. Indian reservoirs indicate the complete spectrum of different types of reservoir found in the world. Their performance in terms of emission of GHGs is more difficult to trace out. In this paper pathways of GHG emission from a reservoir have been discussed and a tool as suggested by UNESCO/IHA has been used to assess the GHG emission from four existing reservoirs in India. These reservoirs are of different age and are located in different parts and climatic zones of India. Predicted diffusive fluxes in CO2eq have been estimated for the year 2013 as well as over the 100 years of their existence in terms of Tonnes CO2eq.

Empowering of Internet of Things to Solve the Customer Engagement Paradox[ ]


Organizations are utilizing mechanical and innovative advances to continuously offer more computerization and convey noteworthy new focal points. Also, as the 1Internet of Things (IoT) creates, one of its essential goals will be the improvement of client engagement procedures to lift up levels. This raised level of robotization touches almost every zone of the venture and, when utilized deliberately, conveys quantifiable primary concern upgrades. No place is computerization more obvious than in the client bolster coliseum, where focal points can mean expanded deals, consumer loyalty, and lower costs. In spite of focal points, if not executed deliberately, unanticipated outcomes may bring about diminished client backing and engagement executively. When appropriately actualized, proactive bolster computerization can convey an ideal answer for both clients and endeavors. It can offer a more finish and effective experience that leaves the client with a positive impression of the organization. Advantages for the endeavor – past upbeat clients – can incorporate lessened work force costs, income upgrade through profoundly relevant cross-offer and up-offer open doors, and better-prepared staff. The idea of the Internet of Things, as recommended by 2Kevin Ashton in 2009, is the conviction of giving an exceedingly enhanced client experience, permitting organizations to viably oversee client engagement. Bolster mechanization can turn out to be more than an effectiveness apparatus with IoT, and offer ascent to a business climate when clients ought to dependably see "robotized support" in a positive light. There are a lot of stories and tales of cumbersome telephone menus and firm choices; effectiveness through bolster robotization ought to never come at the expense of consumer loyalty. Actualizing bolster mechanization through an "as-an administration" plan of action, with adaptable and vital instruments, alongside backing by a learned staff, can rethink client support. It can change a bolster association into a key undertaking resource that encourages data to item advancement, drives extra business from the consumer loyalty it conveys, and improves incomes with extra offering opportunities. Be that as it may, to arrive, we have to know some history.

UNDERSTANDING THE IMPACT OF OUTSOURCING OF HUMAN RESOURCE IN INDIA[ ]


Outsourcing involves the transfer of the management and/or day-to-day execution of an entire business function to an external service provider. The client organization and the supplier enter into a contractual agreement that defines the transferred services. Under the agreement the supplier acquires the means of production in the form of a transfer of people, assets and other resources from the client. The client agrees to procure the services from the supplier for the term of the contract. Business segments typically outsourced include information technology, human resources, facilities, real estate management, and accounting. Many companies also outsource customer support and call center functions like telemarketing, CAD drafting, customer service, market research, manufacturing, designing, web development, print-to-mail, ghostwriting and engineering. Outsourcing and off shoring are used interchangeably in public discourse despite important technical differences. Outsourcing involves contracting with a supplier, which may or may not involve some degree of off shoring. Off shoring is the transfer of an organizational function to another country, regardless of whether the work is outsourced or stays within the same corporation/company With increasing globalization of outsourcing companies, the distinction between outsourcing and off shoring will become less clear over time. The present paper focuses on HR outsourcing Industry in India and its future opportunities.

Review and Framework for Task Allocation for a Robot in Digital Manufacturing: a Simulation Approach[ ]


Digital manufacturing is the use of an integrated, computer-based system comprised of simulation, three-dimensional (3D) visualization, analytics and various collaboration tools to create product and manufacturing process definitions simultaneously. Digital manufacturing allows feedback from actual production operations to be incorporated into the product design process, and allowing companies to take advantage of shop floor realities during the planning stage. Also, simulation of production processes can be performed, with the intent to re-use existing knowledge and optimize processes before products are manufactured. The simulation capabilities of digital manufacturing help to reduce commissioning costs by validating robotics and automation programs virtually. Thus the objective of this paper is to design a framework to implement a task allocation model for a robot in Digital manufacturing, and an empirical investigation on the performance of the system.

MICROSTRUCTURE AND DEFORMATION PROPERTIES OF ALFA COMPOSITES[ ]


Cold upsetting experiments were carried out on as cast and homogenized AA2024/Fly ash composite billets. The study was aimed to evaluate the deformation behavior. Optical and scanning electron micrographic examination of the samples was also undertaken. Hardness measurements were carried out to observe changes, if any, before and after the forging. Specimens were deformed in compression between two flat platens to predict the metal flow at room temperature. The circumferential stress component ÏƒΘ increasingly becomes tensile with continued deformation. On the other hand the axial stress, σz increased in the very initial stages of deformation but started becoming less compressive immediately as barreling develops. FEM simulation analysis of the forging of composite cylinders was then undertaken using Ansys software with a specified diameter-to-height ratio. Detailed comparisons of the experimental variables with the finite element method (FEM) results were carried out to ascertain the accuracy with which the deformation process can be modeled. Predictions from the simulation results were found to be in good agreement with the actual experimentation.

Numerical Simulation of Pulsed Diffusion Flames[ ]


Combustion is a rapid oxidation process in which fuel and oxidizer take part in the reaction by liberating heat.Combustion can be classified as premixed and diffusion based on the initial mixing of fuel with oxidizer.In case of diffused combustion, oxidizer will be diffused into the flame while the combustion products are liberated out of the combustion zone.Since the oxidizer is not readily available for the fuel to combust,the extent of combustion depends on the mixing of fuel with oxidiser.It has been observed by several researchers that,by sending the fuel intermittently will improve the mixing of fuel and oxidizer and thus improves the combustion efficiency.In the present study, a numerical model for unsteady turbulent diffusion flames is developed.The flame characteristics, species concentrations and turbulent parameters are studied along the downstream of the combustion zone.The standard k-εmodel is used to solve the turbulence parameters.A single step chemistry is used to solve the reaction process.The governing equations (flow,energy,species and turbulence equations) are asolved unsteadily using FLUENT.
