Data security is a primary concern for every communication system. Communication becomes an essential tool for any business, education, defense services etc. It is essential to transfer data safe and secure. At present, various cryptography algorithms have been proposed and implemented. Those algorithms are classified into symmetric and asymmetric algorithms based on the number of keys used. Even though several algorithms are used for data security, they are compromise the security at the certain period. Now the idea is to combine the several secure algorithms to provide a highly secure environment for data transmission. The algorithms that are going to be combined are AES symmetric cryptographic algorithm, RSA asymmetric algorithm and MD5 hashing algorithm. With these three algorithms, we can ensure three cryptography primitives confidentiality, authentication and integrity of data.

Congestion management in transmission line is one of the most difficult chores faced by system operator in the rising restructured power system. Congestion in transmission line creates problem for smooth operation in restructured electricity market and increases transmission cost, which leads to profit minimization of the electric power seller and decreases the market efficiency. One of the most effective techniques to get rid of congestion is active power rescheduling of generators. The primary objective of this work is to minimize the rescheduling cost while simultaneously managing the congestion. For optimization of rescheduling cost one of the most recently developed meta-heuristic technique Teaching learning based optimization (TLBO) is employed. In order to establish the usefulness of the proposed methodology it is applied on the standard IEEE 30 bus system to manage three different congestion scenarios at optimal cost. Results thus obtained are found to be qualitatively better than some other standard optimization techniques.

Vehicle routing problem is related to logistics and also called as VRP, which have many applications such as goods delivery, food transferring, supply chain management etc., VRP problem comes under the category of problems, which does not have an exact solution. So that, feasible solutions can be obtained first, later it is possible to find an optimal solution from them, which may further improved by using different algorithms. VRP is an abstraction of travelling sales person problem. VRPTW is a different category of VRP, which includes time constraints additionally, which looks like a multi-objective in the real world., a new memetic algorithm is defined for a central depot vehicle routing problem which achieves multiple objectives concurrently with specified time constraints (MA-MOVRPTW). Here concurrency represents that all objectives have same priority. The objective of MA-MOVRPTW is to find the least cost paths for vehicles to provide services to all customers along with the specified constraints. A local search algorithm existed to satisfy the above specified problem, but memetic algorithm is more efficient than the local search algorithm to produce better results. Finally, a memetic algorithm is provided for minimizing multiple objectives simultaneously with time windows.

Food wastage is a huge problem arising in today's world. It has become a serious issue in our society in the last years that affects “poor and rich countries” equally and according to the Food and Agriculture Organization (FAO) almost half of all produced food will never be consumed. By wasting food we also waste the “time and energy” that we have used to produce the food and as well our “natural resources” and the “limited available agricultural land” will be used up which could be handled in a much better and sustainable way. Additionally, waste has a strong financial impact and affects the environment including the overall greenhouse gas emission. To avoid all such situations we are going to implement IOT Based Smart Garbage and Waste Collection bins (SGWC). Our paper idea is based on creating a social awareness to reduce food wastage through measuring and displaying the amount of food wasted and recycling the wasted food using embedded systems. The Food waste disposal machine (FWDM) used here recycles the wasted food to make fertilizer at planting.
The 3-phase diode bridge rectifier has the least line current distortion among 6-pulse rectifiers; however, its total harmonic distortion (THD) of 31.08% violates power quality standards. This paper reports distortion reduction by lowering magnitudes of harmonics in the line currents using a delta-wye transformer between the 3-phase utility and the diode bridge rectifier. The leakage inductances of the transformer windings provide a filtering effect on the line current harmonics thus providing THD mitigation of utility line currents. The efficacy of the technique is proved by Power System Computer Aided Design (PSCAD) simulations considering the bridge rectifier with and without the delta-wye transformer of vector group Dy1. Experimental results without and with the Dy1 transformer feeding the diode bridge rectifier are presented.

The control of reactive power maintaining the voltage and current waveform of the system as per the standard is done using d-q reference frame. The STATCOM's operations and performance for compensation of reactive power (VAR) are validated by simulation studies using MATLAB/SIMULINK software which confirms the theoretical predictions.
