An Analysis of GPS Code Minus Carrier Measurements for GBAS Applications

--S R Ammana

GPS provides its users with the advantage of two types of range measurements called code measurements and carrier-phase measurements. The difference between both these measurements is called the GPS Code Minus Carrier (CMC) measurement. In this paper, an analysis of the model of GPS CMC measurement is carried out for Ground-Based Augmentation System (GBAS) applications. The analysis has been carried out for several satellites and the results due to three satellites are presented. It is concluded that CMC measurement consists of two times the ionospheric delay (2I) and multipath plus receiver noise component. As the dual frequency receivers provide precise estimate of ionospheric delay component (I), an estimate of multipath plus receiver noise component can be easily obtained from CMC. This technique finds its application in multipath mitigation techniques in GBAS systems all over the world.

A Novel Method for Power System Voltage Stability Monitoring Using Artificial Neural Networks with Reduced Input Dimension

--J R Iyer and B N Suthar

The paper proposes an Artificial Neural Network (ANN)-based method for monitoring the voltage stability margin in electrical power systems. The reactive power loading margin is used as an indicator of voltage instability. Principal Component Analysis (PCA), an efficient feature selection method, is used to select the minimum number of input variables required to approximate the reactive power loading margin with sufficient accuracy and high execution speed. A comprehensive set of input patterns, covering several loading and contingent conditions that may lead to voltage instability in the system, is generated and used for training the ANN. This ANN-based method is successfully implemented on IEEE 14-bus test system. The results indicate that the proposed PCA method provides an effective and coherent ANN model that can successfully and precisely estimate the reactive power loading margin under different system operating conditions employing the fewest possible input features.

Photonic Band Gap Structure for Microwave Applications

--Pooja Sahoo

A new Photonic Band Gap (PBG) unit cell is proposed to improve the value of effective components like inductance and capacitance. It makes it easy to control the cutoff frequency by increasing the effective parameters. The proposed periodic PBG structure provides excellent cutoff and stopband characteristics at different center frequencies. PBG structure shows improved effective inductance using six cells structure, was fabricated with identical periodic and different dimensions. Measurements analyzed on the different fabricated PBG circuits show that the cutoff and stopband center frequency characteristics depend on the physical dimension of the proposed PBG unit cell.

Enhancing Power System Security: A Multi-Objective Optimal Approach to Identify the Location and Size of SVC

--T N V L N Kumar and R V S Satyanarayana

With the growing power demand, the need for innovative and novel methods to operate large interconnected power systems has increased. This reflects more complexity and therefore less secure than before. Hence, modern power systems are more prone to widespread failures. The device that has enhanced the safe and reliable operation of the network and has contributed to capacity augmentation is Flexible AC Transmission System (FACTS). But this is very expensive and must be suitably sized and located to maximize the overall benefit to the system. The paper aims at determining the optimal location and size of the Static Var Compensator (SVC) by optimizing the multi-objective function formulated by different factors that define the system security, namely, voltage deviation, system overload and real power losses. The multi-objective optimization function has been optimized using a Modified Bacterial Foraging Optimization Algorithm (MBFOA). The results are presented and analyzed for an IEEE-30 bus test system and compared with the popular Genetic Algorithm (GA).

Wireless Power Transfer by Means of Inductive Coupling

--Veena Bhat

Wireless Power Transmission (WPT) is the transfer of electrical energy without using any conductor or cable. It is an innovative technology to transmit electrical power with no contact between the source and the load. WPT is very useful in cases where it is hard to transmit energy using conventional wires. In this paper, WPT is adapted through inductive coupling and a practical design is developed in consequence. The magnetic fields generated by the primary coil can be arranged to interact dynamically with matched secondary coil in distant equipment. The inductive coupling WPT works with electromagnetic induction principle, which is based on the principle of a primary coil generating a main magnetic field and a secondary coil being surrounded by that field thereby inducing current within its coils. This causes a relatively short range due to the amount of power required to produce an electromagnetic field. This paper presents the results of an experiment to check the wireless power transfer working with different applications like glowing LEDs and running a fan.

Automated Teller Machines (ATMs): The Changing Face of Banking in India

Bank Management
Information and communication technology has changed the way in which banks provide services to its customers. These days the customers are able to perform their routine banking transactions without even entering the bank premises. ATM is one such development in recent years, which provides remote banking services all over the world, including India. This paper analyzes the development of this self-service banking in India based on the secondary data.

The Information and Communication Technology (ICT) is playing a very important role in the progress and advancement in almost all walks of life. The deregulated environment has provided an opportunity to restructure the means and methods of delivery of services in many areas, including the banking sector. The ICT has been a focused issue in the past two decades in Indian banking. In fact, ICTs are enabling the banks to change the way in which they are functioning. Improved customer service has become very important for the very survival and growth of banking sector in the reforms era. The technological advancements, deregulations, and intense competition due to the entry of private sector and foreign banks have altered the face of banking from one of mere intermediation to one of provider of quick, efficient and customer-friendly services. With the introduction and adoption of ICT in the banking sector, the customers are fast moving away from the traditional branch banking system to the convenient and comfort of virtual banking. The most important virtual banking services are phone banking, mobile banking, Internet banking and ATM banking. These electronic channels have enhanced the delivery of banking services accurately and efficiently to the customers. The ATMs are an important part of a bank’s alternative channel to reach the customers, to showcase products and services and to create brand awareness. This is reflected in the increase in the number of ATMs all over the world. ATM is one of the most widely used remote banking services all over the world, including India. This paper analyzes the growth of ATMs of different bank groups in India.
International Scenario

If ATMs are largely available over geographically dispersed areas, the benefit from using an ATM will increase as customers will be able to access their bank accounts from any geographic location. This would imply that the value of an ATM network increases with the number of available ATM locations, and the value of a bank network to a customer will be determined in part by the final network size of the banking system. The statistical information on the growth of branches and ATM network in select countries.

Indian Scenario

The financial services industry in India has witnessed a phenomenal growth, diversification and specialization since the initiation of financial sector reforms in 1991. Greater customer orientation is the only way to retain customer loyalty and withstand competition in the liberalized world. In a market-driven strategy of development, customer preference is of paramount importance in any economy. Gone are the days when customers used to come to the doorsteps of banks. Now the banks are required to chase the customers; only those banks which are customercentric and extremely focused on the needs of their clients can succeed in their business today.
