This paper presents a novel peculiar functional observer based on quasi-decentralized load frequency control scheme for power systems. The quasi-decentralized functional observers are designed to implement any given state feedback controller based on functional observer theory. The designed functional observers are decoupled from each other to have a simpler structure when compared to the state observer based schemes. The proposed design method is based on the network topology and the proposed functional observer scheme is further applied to a complex nonlinear power system.

Utilization of grid connected photovoltaic systems is facing rise in voltage and reverse power flow problems which are indirectly complicating the reactive power flow control in power system network. It is highly needed to develop an appropriate solution which can control reactive power and for better voltage regulation. In this paper, the reactive power flow control is obtained with the help of reactive power centralized management system in a high voltage distribution along with characteristics of voltage dependent reactive power with photovoltaic system. The control of rise in voltage and reverse power flow is obtained at the medium voltage level which results in reactive power control interchange between in medium and high levels of voltages. The proposed system consists of two radial feeders at the grid connected PV system. The proposed system is modelled using Simulink and the results are provided to explain the reactive power control by controlling rise in voltage and reverse power flow.

Email has become the most widely used and economic form of communication in this digital era. Email users generally get bombarded with unsolicited messages regarding direct marketing often sent to multiple users using bots. Users have to spend a considerable amount of time on clearing such messages. Study shows that there is a sharp increase in spam emails , it is estimated that they are almost 89% of the total email traffic. Spam emails can create havoc by causing financial loss or identity theft of users.Spammers use many techniques to bypass manual filters such as misspelled words by adding extra letters to words (eg: amazing, amaze-on etc..), synonyms of generally used words etc.. Use of Machine learning models can handle such data. Creating text classifiers that precisely filter such emails from the user's mailbox to spam folder is more efficient than manual filters.

With increasing population the crisis of food is getting bigger day by day. During crisis crop diseases are a major threat to food industry, but their rapid identification remains difficult in many parts of the world due to the unavailability of the experts and necessary infrastructure. The recent expansion of deep learning methods has found solution for detection of various plant diseases.Using the dataset which contains several leaf images which were taken in various weather conditions, at different angles. Entire dataset is split into train and test sets. We do image processing using deep learning on the train set and we evaluate our trained model on the test set. During the training we want to get rid of many problems like overfitting and underfitting by make use of regularization or dropout or by increasing number of layers. This model may recognize only some diseases because of the limited dataset available, but we can use this model for detection of any type of disease by providing the large dataset which contains almost all diseases.
