This paper presents the review on different concepts of soil pH detection techniques and technologies. Soil pH is a key parameter for crop productivity therefore its spatial variation should be adequately addressed to improve precision agriculture management system. Soil pH affects the soil's physical, chemical, and biological properties and processes, and thus plant growth. Soil pH, a measure of hydronium ion (H+) concentration traditionally tested in labs to decide how much fertilizer to apply to a field. Recently, with increased emphasis on precision agriculture, economics, and the environment, soil tests are also a logical tool to determine areas where adequate or excessive fertilization has taken place. In addition, they are used to monitor the impact of past fertility practices on changes in a field’s nutrient status. Therefore, developing rapid tools which can detect pH variations on a site-specific basis has become pressing need of the hour because laboratory based methods are inadequate, time consuming, laborious, and expensive. From above perspective, this paper attempts to present review of existing suitable methods, deliberations on pros and cons, and a proposal for pH sensor development which could transmit data wirelessly.

In this contribution we are presenting a simple precipitation hydrothermal method to synthesize zinc oxide (ZnO) nanoparticles using zinc nitrate and starch solution. The obtained precipitated compound was calcined and structurally characterized by Powder X-ray diffraction (XRD), Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and UV-Vis spectroscopic techniques. The powder X-ray data indicates that the calcined compound exhibits hexagonal (Wurtzite) structure with space group of P63mc (No. 186). Scanning electron micrographs show uniform spherical like morphology of ZnO. The SEM results reveal that the particle sizes were in the order of 30–50 nm and the average particle size is around 35 nm. The FT-IR result shows the existence of OH-, NO2- , CO, CO2 groups in unclaimed sample. The band gap was higher for synthesized ZnO particles than their bulk counterparts. The results indicate that starch is an attractive material that can be used as precipitation agent for preparing ZnO.

In today’s world, energy is becoming a precious resource. Life without electrical energy seems like a faraway nightmare. Yet, people in many rural areas live with no electricity at all. A small device which traps solar energy or which stores energy converted from mechanical forces can come a long way in electrifying these areas. Even just a single light bulb capable of glowing through the night can make a difference in their lives. Thus here is a hybrid solar and muscle powered solution. This report shows one such prototype built and the improvements and modifications which can be made in it.

Different types of distributed generation (DG) sources could be connected to the main power grid in order to improve the reliability of the power system, in a smart grid. The association of ac and dc distribution grid are assigned for the efficient connection of renewable power resources. In this function, one of the major difficulties due to these integrations is the excessively large in the fault current due to the activity of DG in the smart grid. A superconducting fault current limiter (SFCL) could be applied, to protect the smart grid from increasing fault current, which has very less power loss and ability to limit initial fault currents effectively. This paper presents validity analysis results of the location of the SFCL and its effects on decreasing fault current in a smart grid having ac and dc microgrid. The entire power system was implemented with a low voltage dc grid connected with a photovoltaic farm and a microgrid having wind farm . Validity analyses were performed for the severe faults with the various SFCL locations. The dynamic location of SFCL in power grid, which could limit fault currents and a positive effect on the DG sources, is found to be the connection point of integration of the each DG sources in the micro grid.

Since discovered, electrical energy became one of the world’s fastest growing energy technologies. Efficient and stable utilization of electrical energy is one of the most important problem. The major phenomena that effects on the quality of power supply is the harmonics caused by different loads connected to the grid, which are usually converters based on power electronic components. These are the main causes for the deterioration of power quality. This paper presents the harmonic compensation of linear loads fed by matrix converter and the performance of two types of controllers(namely, Adaptive Fuzzy control and Adaptive Neural Fuzzy Inference system) are compared, during balanced supply and abnormal grid conditions. The sinusoidal nature of output currents were preserved by using PWM method and optimum Venturini method employed for matrix converter.

This paper proposes single phase AC-DC SEPIC converter using closed loop techniques for domestic and industrial applications. The Single Ended Primary Inductor Converter (SEPIC) is a type of DC-DC converter allowing the electrical potential (voltage) at its output to be greater then, less then, or equal to that of its input. A SEPIC converter is similar to the BUCK-BOOST and BOOST-BUCK converter, but has advantages of having non-inverted output (The polarity of the output voltage is same as that of the input). There are two types of techniques, open loop and closed loop technique. In open loop, a non-isolated SEPIC converter is used. This has lower power factor and high THD. Hence the closed loop technique is used to improve power factor and THD. The control techniques are voltage follower approach and average current control technique. By using the above techniques the power quality parameters will be improved when compared to open loop. The simulation of SEPIC converter is done by using the software tool PSIM (Power Simulation).

This paper deals with design of controlled adder /subtractor cell using Shannon based full adder with pass transistor logic. The proposed adder used only 14 transistors for full adder implementation. Simulations were performed by Microwind 3.1 and DSCH 2 VLSI CAD tools and BSIM 4 for parametric analysis of various features. The analysis is done on the basis of power consumption, delay and area occupied and theses are compared with previous papers and we are good to enhance these parameters.

Generally conventional boost converters have been used to obtain higher output voltage than the input voltage. When these boost converters are operated for high ratios it leads to high voltage and current stress on the switch. Hence an interleaving technique of boost converter has been presented. This method of approach can be used in high power applications to produce high voltage gain when compared to the conventional boost converter. This project report deals with the simulation of Interleaved Boost Converter (ILBC). It is seen that, for higher power applications, more modules can be paralleled to increase the power rating and the dynamic performance. One of the challenges in designing a boost converter for high power application is how to handle the high current at the input side. In this project report an interleaved boost dc-dc converter is proposed for current sharing on high power application. Moreover, this converter also reduces the ripple of voltage. The simulated results are presented with R load.

The increase in power demand has forced the power system to operate closer to its stability limit. Voltage instability and line overloading have become challenging problems due to the strengthening of power system by various means. The nature of voltage stability can be analysed by the production, transmission and consumption of reactive power. One of the major causes of voltage instability is the reactive power unbalancing which occurs in stressed condition of power system. Flexible AC transmission system (FACTS) devices play an important role in improving the performance of a power system, but these devices are very costly and hence need to be placed optimally in power system. FACTS device like static var compensator (SVC) and thyristor controlled series compensator (TCSC) can be employed to reduce the flows in heavily loaded lines, resulting in a low system loss and improved stability of network. In this paper, a method based on line stability index, real power performance index and reduction of total system VAR power losses has been proposed to decide the optimal location of TCSC. Now a day, Voltage Stability has become a major concern in power systems planning and operation. This problem has become very complex due to the continuous growing on system interconnections and demand for electricity and also due to economical and environmental constraints to properly expand the system. This has increased the importance of implementing suitable and efficient techniques for improving voltage stability of stressed power system. FACTS are one aspect of the power electronics revolution that is taking place in all areas of electric energy.
