Transmission pricing is mainly adopt the issue of recovering embedded cost and optimal allocation of variable cost at different nodes over the grid. Pricing aim to translate transmission cost into tariffs to enable competition, lead to economic efficiency, enable the grid owner to recover his cost and more transparent to market participants while maintaining supply security and reliability of the system. These transmission pricing depends on generator, load levels and transmission line constraints. Transmission line constraints result is variations in energy prices throughout the network. The proposed approach is based on AC optimal power flow model with considering of losses. Resulting optimization problem is solved by linear programming approach. Locational Marginal Pricing methodology is used to determine the energy price for transacted power and to manage the network congestion and marginal losses. Variation of LMP values with transmission constraint conditions also studied. Simulation is carried out on IEEE 57 bus system and 765kV/400kV MSETCL system of Maharashtra transmission line for real data bus system and the results are presented.

In the present era, food scarcity and water scarcity occurs due to the increase in population. So to avoid this problem we have to promote the agriculture sector. But water wastage is more in this sector in the form of water logging while watering the agricultural fields through irrigation. Therefore an automatic plant irrigation system has to be designed for the proper water supply in the fields. This paper deals with an automatic plant irrigation system which automatically senses the moisture content of the soil and decide whether irrigation is needed or not and how much water is needed for soil. This system uses AtMega328 microcontroller. It is programmed to sense the moisture content if the soil over a period of time. When the moisture content is less than the limit which is predefined, it will start supplying the desired amount of water till it reaches the limit. So when the soil is dry the pump will automatically water the fields and when the soil is wet the pump will automatically switch off, there by eradicate the need of manpower and conserve the time.

The role of digital adder in Digital system design using Very Large Scale Integration (VLSI) technique is very important. The performance of low power VLSI based adder design has been affected by Propagation Delay (PD) problem. A survey of adder's availability for low power VLSI design with minimum PD is done with the help of Parallel prefix adders design. This paper clarified about the design and analysis of various Parallel Prefix Adders (PPA) also compared with the performance of these adders on the aspects of area, delay and power. From the investigation results it clears that the Kogge stone adder (KSA) is superior for the delay process, so the speed of the addition is automatically increased. But it takes more power consumption and area.

In today's age of Information and Cyber technology, videos and pictures are having a wider range of applications such as authentication, military, law enforcement, information sharing etc. The easily available state of the art editing tools and modern highlyclassy digital cameras make simpler the tampering of captured images by the fakers. Copy-move method in digital images occurs when a specific slice of the image is fixed to another area of the same image to hide or shield objectionable objects. Forgery detection methods aim to figure out the pasted partsor the fake regions. The persons who do tampering usually do many pre or post operations like rotation, filtering, compression, resizing etc. on the images before pasting them on to another or same image. Therefore, the tampering detection practices are to be very tough for any such operations. This research paper surveys the innovative experiments in the forgery recognition tactics built on the likeness and connection between the pasted part and the real image and their comparative study.

A typical Geostationary Satellite which is used to receive and retransmit signals from the earth. A communication satellite is capable of receiving and retransmitting one or more independent signals. The electronic equipment used to amplify and shift the frequency of each signal is called a transponder. In this paper a Low Noise Amplifier for satellite transponder application at 10GHz is designed. This proposed LNA is used to amplify the weak signal at the front end of the receiver. The Low Noise Amplifiers are implemented using PHEMT and GaAsFET. The parameters are such as input return loss (Su), output return loss (S22), gain (S2i) and noise figure are simulated by using ‘ADVANCED DESIGN SYSTEM(ADS)’ and results are shown.

Amplification is one of the most vital operation in modern RF and microwave communication systems. Earlier microwave amplifiers were made of tubes like klystron, TWT's etc. but due to the development of solid state device technology now-a-days the microwave amplifiers are often designed using these devices like BJT's, FET's and newly developed heterojunction devices like HBT's and HEMT's. At the receiver of a communication system the first element being an antenna receives both the information signal and noise which is amplified by first amplifier. But noise is the unwanted component which need to be minimized for which the low noise amplifier is designed. The low noise amplifier is designed to minimize noise by considering the trade-off between the impedance matching, choice of amplifier technology and selecting low noise biasing conditions. In this work we have tried to achieve the goals for the C band of microwave frequencies i.e. from 4 to 8 GHz using Advanced Design System (ADS) simulation software.

Accurate channel state information estimation in a time variant environment is a significant problem in Multi-Input Multi-Output (MIMO) — Orthogonal Frequency Division Multiplexing (OFDM) systems. Generally channel coefficients of a time variant wireless channel are obtained using Adaptive Channel Estimation (ACE) algorithms. One of the simple and stable ACE methods is based on the Normalized Least Mean Square (NLMS) algorithm. But, it cannot make use of the intrinsic sparsity of broadband MIMO wireless channel. This paper proposes a Variable Step Size-Sign Data Sign-Error Normalized Least Mean Square (VSS-SDSENLMS) algorithm for Adaptive Sparse Channel Estimation (ASCE) which is based on the application of sparse penalties to the cost function of SDSENLMS algorithm.

Artificial lighting is one of the visible source energy consumption in any industries. Energy consumption can be minimized by enhancing the daylight availability in the building. In this paper, daylight availability in the interior of a low rise building located in the composite climate of India, based on the actual design of the building is studied. Based on the results of preliminary analysis, two strategies to enhance the daylight penetration to the interior of the building i.e. increasing Visual Light Transmittance (VLT) of the window glass and adding new windows at the south west facade are proposed and analyzed in this paper. Simulation based study is adopted using Ecotect modeling tool and Radiance software. Illuminance in lux is taken as the performance indicator in this study. The results indicate that, with the fixed design and orientation of the building, adding windows on south west facade with 35% VLT gives the maximum optimally illuminated area in the building.

This paper aimed to apply the IPSO algorithm for optimizing the TCSC parameters as well as system parameters towards voltage stability enhancement. The case studies are performed on IEEE 14-bus test system. Since the role of FACTS devices is to control main power flows and hence the economics involved in congestion management are not focused in the simulations. Various operating conditions are considered to show the effectiveness of TCSC on power flow control in the network.

An important applications of C band microwave frequencies is the Wireless LAN (WLAN) operating at 5 GHz. Since the frequency of operation has increased from 2.45 GHz to 5 GHz the susceptance of noise also increases and hence the selectivity of the receiver initial stages should be very high to remove these noise components and send a clean information to the receiver destination. The initial stage of the receiver is the low noise amplifier which is nothing but microwave amplifier often designed using the highly advanced solid state devices like BJT's, FET's and newly developed heterojunction devices like HBT's and HEMT's. In this work we have taken an initiative to design the low noise amplifier using Advanced Design System (ADS) simulation software with high selectivity and sensitivity that minimizes the noise by considering the trade-off between the impedance matching, power gain, stability and selecting low noise biasing conditions.
