Abstract
Investigations were carried out to evaluate the performance of a medium grade low heat rejection (LHR) diesel engine with ceramic coated cylinder head with 3-mm air gap with different operating conditions [normal temperature and pre-heated temperature] of crude rice brawn oil (CRBO) with varied injection pressure and injection timing. Performance parameters of brake thermal efficiency, exhaust gas temperature, volumetric efficiency and sound intensity were determined at various values of brake mean effective pressure (BMEP). Exhaust emissions of smoke and oxides of nitrogen (NOx) were recorded at the various values of BMEP. Combustion characteristics at peak load operation of the engine were measured with TDC (top dead centre) encoder, pressure transducer, console and special pressure-crank angle software package. Conventional engine (CE) showed deteriorated performance, while LHR engine showed compatible performance with CRBO operation at recommended injection timing and pressure and the performance of both version of the engine improved with advanced injection timing and at higher injection pressure when compared with CE with pure diesel operation. The optimum injection timing was 32obTDC for CE while it was 29obTDC with LHR engine with CRBO operation. Peak brake thermal efficiency increased by 7%, smoke levels decreased by 2%, NOx levels increased by 24% and sound intensity decreased by 12% with CRBO operation on LHR engine at its optimum injection timing when compared with diesel operation on CE at manufacturer's recommended injection timing of 27obTDC. (Before top dead centre)

Abstract
An analytical threshold condition for the prediction of onset of horseshoe chaos is obtained in the Duffing–van der Pol oscillator driven by different periodic forces using the Melnikov method. The external periodic forces considered are sine wave, square wave, symmetric saw-tooth wave, rectified sine wave and modulus of sine wave. Melnikov threshold curve is drawn in a parameter space. Analytical predictions are demonstrated through direct numerical simulation. Numerical investigations including computation of stable and unstable manifolds of saddle and measuring the time elapsed between two successive transverse intersections are used to detect onset of horseshoe chaos.

Key words: Duffing- van der Pol oscillator, Horseshoe chaos, Melnikov function, periodic forces, chaos.

Abstract
The engine speed controller of a conventional diesel engine is called a Governor. In order to control engine speed, the governor controls the amount of fuel using fuel rack. The fuel rack is connected to throttle actuator lever and driven from microcontroller. The actuator motion is controlled to achieve set-point rpm so required pulse width modulation duty cycle to drive actuator is calculated from digital PID algorithm. PIC 16F877A microcontroller based hardware is developed for the implementation of the controller. The system broadly involves interfacing hardware and the software for PID algorithm. A continuous PID controller is governed by an equation which describes the dynamic time varying behavior of the input or the error signal. This is digitized using numerical approximations and is programmed in the microcontroller. This system is a closed loop control system with feedback signal generated by a digital magnetic pickup, which gives a pulse output which is TTL compatible. The PID algorithm along with the hardware achieves the speed control of the diesel engine. The hardware and software are validated in real time by considering different speed settings.

Keywords: Electronic Speed Governor, PID, Throttle Actuator, PIC16F877A, Pulse width modulation.

Abstract
International Economic Integration plays a vital role in Economic Development of any country. Foreign Direct Investment is one and only major instrument of attracting International Economic Integration in any economy. It serves as a link between investment and saving. Many developing countries like India, are facing the deficit of savings. This problem can be solved with the help of Foreign Direct Investment. Foreign investment helps in reducing the defect of BOP. The flow of foreign investment is a profit making industry like insurance, real estate and business services and serving as a catalyst for the growth of economy in India. The present study is based on the objectives like (a) to know the requirement of amount of foreign investment by India, for its economic Development and (b) to analyze the trend and role of FDI & FIIs in improving the quality and availability of goods has been beyond doubt. To analyze all these objectives data has been gathered through secondary sources like reports and publication of Govt. and RBI relating to foreign Investment. After analyzing all the facts it may be concluded that maximum global foreign investment's flows are attracted by the developed countries rather than developing and under developing countries. Foreign investment flows are supplementing the scare domestic investments in developing countries particularly in India. Further this paper recommends that we should welcome the inflow of foreign investment because it enable us to achieve our cherished goal like making favorable the balance of payment, rapid economic development, removal of poverty, and internal personal disparity in the development and also it is very much convenient and favorable for Indian economy.

Keywords –Foreign Direct Investment, Foreign indirect investment, Internal Personal Disparity, Portfolio Investment Policy, Balance of Payment

Abstract
Climate change poses uncertainties to the supply and management of water resources. The Intergovernmental Panel on Climate Change (IPCC) estimates that the global mean surface temperature has increased 0.6 ± 0.2 oC since 1861, and predicts an increase of 2 to 4 oC over the next 100 years. Temperature increases also affect the hydrologic cycle by directly increasing evaporation of available surface water and vegetation transpiration. Consequently, these changes can influence precipitation amounts, timings and intensity rates, and indirectly impact the flux and storage of water in surface and subsurface reservoirs (i.e., lakes, soil moisture, groundwater). In addition, there may be other associated impacts, such as sea water intrusion, water quality deterioration, potable water shortage, etc. While climate change affects surface water resources directly through changes in the major long-term climate variables such as air temperature, precipitation, and evapotranspiration, the relationship between the changing climate variables and groundwater is more complicated and poorly understood. The greater variability in rainfall could mean more frequent and prolonged periods of high or low groundwater levels, and saline intrusion in coastal aquifers due to sea level rise and resource reduction. Groundwater resources are related to climate change through the direct interaction with surface water resources, such as lakes and rivers, and indirectly through the recharge process. The direct effect of climate change on groundwater resources depends upon the change in the volume and distribution of groundwater recharge. Therefore, quantifying the impact of climate change on groundwater resources requires not only reliable forecasting of changes in the major climatic variables, but also accurate estimation of groundwater recharge. A number of Global Climate Models (GCM) are available for understanding climate and projecting climate change. There is a need to downscale GCM on a basin scale and couple them with relevant hydrological models considering all components of the hydrological cycle. Output of these coupled models such as quantification of the groundwater recharge will help in taking appropriate adaptation strategies due to the impact of climate change. This article presents the likely impact of climate change on groundwater resources, climate change scenario for groundwater in India, status of research studies carried out at national and international level, and methodology to assess the impact of climate change on groundwater resources.
