Abstract: In this paper work, especially in India, we need to concentrate on certain aspects of increasing the productivity level and subsequent profit of agriculture and reducing the financial issues and thus solving the problems of farmers. Today in India, farmers use conventional methods for cutting / harvesting crops, using human labor but this method consumes a lot of time and energy. It is well known that crops like Jowar, Tuar, Bajra, Maize require more force in contrast to the crops like wheat, rice etc., need. This project presents a vital concept for design and analysis of crop cutters. The crop cutting is an important phase in the field of agriculture. It can be used for cutting dry stalks of grain, breaking trunk of tree. This mechanism is used for harvesting the moderate crop. But a single machine can do a work of 7-8 laborers and help to increase the economy of farmers. The only drawback of machine is that it depends on battery and it works automatically without using man power.

Abstract: Quadrotor (or quadcopter), a typical unmanned aerial vehicle (UAV), has many applications in daily life, military, agriculture, industry, commerce, and other useful applications. Control for stabilizing quadrotor is the main point needed to be solved before making tracks along the desired trajectory. This research presents an explicit scheme to design a PID regulator for stabilizing quadrotor. For more details, the mathematical model of quadrotor is defined under an engineering point of view, based on which a suitable PID controller is designed and programmed on STM32 microcontroller. Furthermore, a good control feedback system needs a clean feedback signal, so the effects of sensor noises are decreased by applying the complement filter. The performances of the control system and how sensor noises are well eliminated are going to be demonstrated by simulation and experimental results.

Abstract: Load forecasting is the technique for prediction of electrical load. In a deregulated market it is much need for a generating company to know about the market load demand for generating near to accurate power. If the generation is not sufficient to fulfil the demand, there would be Problem of irregular supply and in case of excess generation the generating company will have to bear the loss. Neural network techniques have been recently suggested for short-term load forecasting by a large number of researchers. This paper proposes the load forecasting for the Power Grid Company Bangladesh Ltd. (PGCB) by using Artificial Neural Network (ANN). It uses the advanced back....
