Abstract :Removal of weeds from sugarcane fields is of utmost importance for optimizing sugarcane
production. If weeds are not removed from sugarcane field at the right time, the yields are estimated fifty
percent reduced. The traditional weeds control in sugarcane is chemical usage even though it is unsafely and
unfriendly to environment. The mechanical weed control is one of the optimized methods of green technology;
The spring tine cultivator attached to a small side riding tractor was developed by Agricultural Engineering
Research Institute Five legs of coil spring tine were set in 2 rows; two and three times in first and second row by
arranging in different positions. Of the two types of developed spring tine cultivators, type I used a coil shank
and a full sweep head tine is called coil spring type |

Abstract :An efficient and optimum economic operation of electric power generation systems has always
occupied an important position in the electric power industry. A power system operation at minimum cost is no
longer the only criterion for electrical power dispatch. Combined economic emission dispatch problem is
obtained by considering both the economy and emission objectives with required constraints. The purpose of
Combined Economic and Emission Dispatch (CEED) is to minimize both the operating fuel cost and emission level
simultaneously while satisfying load demand and operational constraints. This paper presents an optimization
algorithm, for solving security constrained combined economic emission dispatch problem, through the
application of programming method |

Abstract :Authors analyzed and explored a significant concept of rectangular microstrip patch antenna
configured by double negative left handed metamaterial which have dielectric permittivity & magnetic
permeability both negative simultaneously. Metamaterials are artificial structures exhibits double negative
properties. They can control Electromagnetic radiations by quantum mechanics. This work deals with
miniaturisation of patch antenna using metamaterial. Rectangular microstrip patch antenna without proposed
metamaterial is designed to resonate at 2.322 GHz. The antenna with metamaterial is proposed and analyzed
at a height of 3.276 mm from the ground plane |
