Automatic Pump Controller for Solar Photovoltaic Irrigation System

The need of electricity for rural areas, especially for water supply systems, is crucial for farmers. Stand-alone solar systems are applicable for areas no power grid, in this system is operated when the radiation is sufficient to supply the system with can be stored water and energy. The main purpose of this journal is to develop a solar watering system capable of performing irrigation task automatically. 

This system uses sensor that determines soil moisture by soil moisture sensor for watering pump, water level indicator also its pumping system from well to water tank that detects ultrasonic sensor. In this system, a pump is powered by solar photovoltaic which controlled by Arduino Uno. And this journal also discusses the prototype design of microcontroller based on water irrigation which detects a soil if watering is required then the water will be maintained at the constant level.

And the system is designed by applying an ultrasonic sensor, an Arduino Uno microcontroller, and a pumping machine in order to automatically switch the water filling. The prototype has shown that the system able to reduce wasteful electrical energy and human intervention at minimum cost as the entire system runs only using solar energy. The prototype can be proposed to handle the water pump problems due to the utilizations of the manual switch as well as the floating ball tap to stop the water tank filling.

A Study on Mesh Free Methods: A Different Form of FEM

Roots of Mesh-free methods go back to the seventies. The major difference to finite element methods is that the domain of interest is discretized only with nodes, often called particles. These particles interact via mesh-free shape functions in a continuum framework similar as finite elements do although particle "connectivity" can change over the course of a simulation.

This flexibility of mesh-free methods has been exploited in applications with large deformations in fluid and solid mechanics, e.g. to name a few, free-surface flow, metal forming, fracture and fragmentation, to name a few. Though there are a few publications on mesh-free methods formulated in an Eulerian (or ALE) description, e.g. Fries 2005, most mesh-free methods are pure Lagrangian in character.

The non negligible advantages of mesh-free methods as compared to finite elements are: their higher order continuous shape functions that can be exploited e.g. for thin shells; higher smoothness; certain advantages in crack propagation problems. The most unhidden drawback of mesh-free methods is probably their higher computational cost, regardless of some instabilities that certain mesh-free methods have. The paper deals with the basic methodology of mesh-free methods along with the mathematics involved.

Performance Analysis of Congestion Control Algorithm for Mobility Model in Mobile Ad-Hoc Networks (MANET)

The mobile ad-hoc networks (MANET) is network where the mobile nodes move randomly and freely without any centralized administration or control. Where mobile nodes in MANET works both as routers and as hosts. As we know the challenges faced by the wireless and distributed nature of ad hoc networks such the chances of losing packets over the network increases to a great extent as well as the packet loss occurring with the increase in size of the data packets which are often responsible for congestion in the network.

Now In order to detect congestion in the network, there are various congestion control algorithms are used. This paper gives a study of the congestion control algorithm used in MANET' and tries to propose a simple congestion control algorithm for mobility models such as random walk model for MANET'. The objective of this paper is to design an efficient congestion control technique to reduce the amount of congestion in the network.

Li-Fi Technology in Wireless Data Communication

Light Fidelity (Li-Fi) technology is a novel method of wireless communication network based on the use of visible LED lights between the violet (800 THz) and red (400 THz) to transmit data wirelessly. Li-Fi has much broader spectrum compared to conventional methods of wireless communication for data transmission which depends on radio waves. The principle of Li-Fi is based on sending data by amplitude modulation of light source in a well-defined and consistent way.

The concept of Li-Fi assures to solve issues like shortage of radio-frequency bandwidth and eliminates the drawbacks of Radio communication technologies. Li-Fi technology provides better bandwidth, faster transfer speed, efficiency and security as compared with Wi-Fi. This paper focuses on working of Li-Fi, its applications, features and comparison with existing technologies like Wi-Fi etc.

Effect of Voltage Sag on an Induction Motor

The aim of this paper is to analyze the performance of the three-phase squirrel cage induction motor under various voltage fluctuation levels. Generally, Induction motor drives are preferred for its simple and easy control. Their performance depends on relative power supply quality such as voltage sag, harmonics, voltage unbalance and voltage fluctuations. The induction motor is more sensitive to voltage fluctuations within certain amplitude levels and frequencies. This paper presents a study of voltage sag effects on an induction motor using simulation. In this paper, the impact of voltage fluctuations on induction motor performance is investigated.

Evaluation of Compression Lines and Aging Effect on Clayey Soils

the intrinsic compression lines (ICL) obtained from this study can be used for studying the compressive behaviour of clayey soils due to aging effect. The results of oedometer tests of undisturbed samples were compared with the corresponding results of recomposed samples at room and high temperature and slurry samples. 

The values of compression index, Cc and pcpe*, where pc is the preconsolidation pressure and pe* is the equivalent pressure on the compression curve of slurry (1.5wL) sample when the sample yields, of undisturbed samples are different from those of recomposed samples due to the effect of soil structure. The compression lines of slurry samples obtained from the relationship of void index and effective overburden pressure can be expressed by the equations with sufficient accuracy. 

The values of void index difference, ? Ivy can be used to find the effect of the enhanced resistance to compression of natural soil structure. If ? Ivy value is high, there will be high maximum value of compression index after destroying the resistance of soil structure caused by the aging effect. The proposed compression index ratio, r"™ obtained from the Iv-log p relationship can be considered as a useful index to represent the aging effect.
