Artificial neural network approach for modelling of heat exchanger with different baffle segment configurations
In this work, two neural networks namely Cascade Feed Forward Neural Networks (CFFNN) and Feed Forward Neural Networks (FFNN) are modelled for the prediction of shell side pressure drop and heat transfer coefficient heat exchanger from its hot water flow rate. Simulation results showed that for same shell side mass flow rate, Heat transfer coefficient, pressure drop and heat transfer rate are found to be maximum with single segmental baffles. All the two ANN models are trained, validated and tested which predicted the shell side pressure drop and heat transfer coefficient of the Heat exchanger with acceptable accuracy and the both Neural Network is found to have the best accuracy by having the best Regression due to its feedback connections

A review of artificial neural network approach for modelling of heat exchanger with different baffle segment configurations
Development of computer-based algorithms for various heat transfer applications is emerging as a successful tool in the field of thermal engineering. Artificial intelligence algorithms used in this field are simple models of human intelligence and evolutionary experience. The methods used for such analysis include using fundamental equations, employing conventional correlations, or developing unique designs from experimental data through trial and error. Also the heat transfer problems are becoming increasingly more complex and that the need for modelling single steady phenomena requires dealing with dynamics, system performance, optimization, and control. To overcome this difficulty, a simple artificial neural network (ANN) method has been implemented in various heat transfer studies based on databases available from experimentation. This work provides an overview of the literature on the works carried out in the analysis of Heat Exchangers, Shell and Tube Heat Exchanger, Compact Heat Exchangers and emergence of ANN simulation for thermal systems which are relevant for present studies.

The economy of Gujarat and its policies
Governmental policies and its impact on the development of Gujarat as the economy of Gujarat is one of the fastest growing economies among all Indian states. The State emerged stronger and a symbol of hope for the rest of the country in terms of economic and industrial development. Gujarat is one of the states to have responded punctually and effectively to the new liberal policies. The government has been open to new ideas, technology, including organizational and management governance practices, and has designed policy responses to overcome economic challenges. The analysis in this paper suggests that stakeholders in Gujarat have been able to create an environment in which improving quality of living, focusing on basic needs, and quality of life are the main focus of public policies and discourse. Such focus is favorable to broad-based growth and upward economic and social mobility, and diversity, permitting introduction of new ideas in organizing different activities.

Political participation of women in India
Women are involved less in politics. In any political system, right from the developed to the developing countries, women’s participation is far less compared to men. Political participation means not only exercising the right to vote but also power-sharing, decision making, policy making at all levels of governance of the state. Participation of women in this political activity is almost equal to men. Women are not yet well represented in the political arena, for which they have to participate in the public sector such as membership in parliament and state legislative assembly. The Constitution not only grants equality of treatment to women but also calls upon the state to accept measures favoring women neutralizing the socio-economic, educational and political disadvantages that they face.

Simulation analysis of static VAR compensator for the improvement of power quality and efficiency of transmission line
This paper describes the effects of static VAR compensator on varying voltages in the system and the role of SVC in stabilizing these voltages. SVC is a relatively new technique for stabilizing the system voltages. It can control voltage accurately, continuously and rapidly. It helps in improving the transient stability of the system and voltage Variations due to sudden surges like lightning etc. The most important quality of SVC is that it can provide both the inductive and capacitive power as required. Simulink toolboxes are used in this paper to construct the static VAR compensator. The SVC consist of two main parts, Thyristor Switched Capacitor (TSC) and Thyristor Controlled Reactor (TCR). There are 3 TSC units and 1 TCR unit used in designing SVC. The TSC units will provide the capacitive power when the system voltage decreases than the rated voltage. The capacitive unit has the leading properties. In case the system voltage decreases by a large magnitude, multiple TSC units will be operated at the same time. Whereas TCR unit provides the inductive power when the system voltage increases than the rated voltage. The inductive unit has the lagging properties. A programmable voltage source is used in the simulations to vary the system voltages as desired by the user to check the response of the SVC controller. The author has also visited and reviewed the practical implementation of the SVC at one of the grid station and has used the same parameters in this paper as in the system implemented at the grid station. The SVC installed at the grid station has not been energized yet. This paper helps the author to compare the results of the simulations of the SVC implementation with that of practical one once the SVC is energized at the grid station. The results of the report show that the SVC works very effectively in keeping the system voltage stable in case of sudden Variations in voltages and reacts very quickly to the Variations. It can be concluded from the results that the SVC is an important part of the power system for the continued stability and reliability of the system.

Postharvest application of calcium salts on fruit quality of guava during storage
Guava is one of the most popular fruit grown in the tropical, sub-tropical and some parts of arid regions of India. Retailing of guava fruit in India is usually carried out without refrigeration. Therefore preservation of fruit at room temperature is highly desirable to reduce post-harvest loss and improve its commercialization. The post-harvest loss of guava in India is about 25-30%. Post-harvest dipping is one of the emerging technologies to increase the shelf life of fruits by retaining the fruit quality and control of the spoilage. The present investigation was carried out with this main objective to compare the efficacy of calcium chloride and calcium nitrate for shelf-life enhancement and fruit quality of guava. Fruits were treated with 1% of calcium chloride and calcium nitrate, 2% of calcium chloride and calcium nitrate and no treatment for control samples of guava. The physiological loss of weight, chemical parameters like TSS, ascorbic acid, and reducing and total sugar content were observed and compared with untreated guava fruits. In the current study it was observed that reduction in PLW and retention of ascorbic acid was more in 2(No3)2 treated samples than the other samples. However, TSS, reducing sugars and total sugars were retained more in 1cl2 treated samples than the other treated samples when compared with control samples of guava. The application of 2(No3)2 and 1cl2 recorded a potential shelf life of guavas during storage.
