An aircraft is a machine that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil or in a few cases the downward thrust from jet engines. Combat aircraft is any fixed wing or rotary wing aircraft which are designed to destroy enemy equipment using their own aircraft ordnance. Combat aircraft are normally developed and procured only by military forces. The main role of fighters is destroying enemy aircraft in air-to-air combat, offensive or defensive. Many are fast and highly maneuverable. Escorting bombers or other aircraft is also a common task. They are capable of carrying a variety of weapons, including machine guns, cannons, rockets and guided missiles. Many modern fighters can attack enemy fighters from a great distance, before the enemy even sees them.

Design and Development of CNC Based Maintenance and Safety System for High Rise Building
(2017-10-11T06:25:06Z) Baldev, Raj C; Anwin T V, Joseph; Jerry, Sabore
Cleaning and maintenance of high rise buildings not only is a tedious but also a dangerous affair. The major concern being very little or almost no accessibility to certain areas of the building which requires work. A Hazard survey by “EMIRATES 24/7” rated and perceived window cleaning as the most dangerous job in the country. The modern day techniques not only is less efficient but also prone to risk involving human lives. The possible and effective replacement for the modern day techniques is a CNC based mechanism. The CNC mechanism makes use of program instructions and codes to run a machine tool incorporated with a wiping mechanism which is used for high rise buildings allowing movement in a defined axis only. The movement of the wiper is by means of sliding mechanism in a lateral or transverse direction depending on where it is required. The axes are well defined and is relative to the building. Not only does this completely eliminate the need for human effort the mechanism is also economical in use and effective over the modern techniques.

Plastic have been one of man’s means of bearing items or contents, widely used by majority in the world. This material is readily used with ease because of its characteristics which include resilience, lightness, resistance to corrosion, and ease of processing. One of many problems facing the world today is the environmental waste control. For more than two decades, the amount of plastic waste littering the streets has been of crucial environmental problem. The proper system of plastic waste collection is missing, and the people are not educated as to the problems of plastic waste. Every home generates waste from plastic, ranging from used nylon’s, plastic bottles down to big plastic containers like buckets, jerry cans, kegs, and so on. However, the non-biodegradable nature of plastic waste poses a big problem since these wastes can stay longer in our environment causing all sorts of problems. Biodegradable waste accounts for over 50% of waste generated with other component estimated at different composition in different states. Due to the non-biodegradable nature of plastic waste, the way forward for plastic waste

working fluid to transfer heat. Thermal energy is absorbed and released as the working Fluid undergoes expansion and compression and changes phase from liquid to vapor and back, respectively. Semiconductor thermoelectric coolers also known as Peltier coolers offer Several advantages over conventional systems. They are entirely solid-state devices, with no moving parts; this makes them rugged, reliable, and quiet. They use no ozone-depleting chlorofluorocarbons, potentially offering a more environmentally responsible alternative to conventional refrigeration. They can be extremely compact, much more so than compressor-based systems. Precise temperature control can be achieved with Peltier coolers. However, their efficiency is low compared to conventional refrigerators. Thus they are used in niche applications where their unique advantages outweigh their low efficiency. Although some large-scale applications have been considered Peltier coolers are generally used in applications where small size is needed and the cooling demands are not too great, such as for cooling electronic components.

Indian agriculture needed production and protection materials to achieve high productivity. Agriculture fertilizer and chemical frequently needed to kill insects and growth of crops. The pesticide affects the nervous system of humans and also leads to disorders in body. The application of pesticides and fertilizers in agricultural areas is of prime importance for crop yields. However, some factors may reduce the yield, or even cause damage (e.g. crop areas not covered in the spraying process, overlapping spraying of crop areas, applying pesticides on the outer edge of the crop). Climatic condition, such as the intensity and direction of the wind while spraying add further complexity to the control problem. In this report, we describe an architecture based on unmanned aerial vehicles(UAVs) which can be employed to implement a control loop for agricultural applications where UAVs are responsible for spraying chemicals on crops. The process of applying the chemicals is controlled by means of the feedback obtained from the wireless sensor network (WSN) deployed on the crop field. . A remote controlled UAV (Unmanned Aerial Vehicle) is used to spray the Pesticide as well as fertilizer to avoid the humans from pesticide poison. The UAV is operated by manual flight plans and the Sprayer is manually triggered by RF controlled Nozzle. The aim of this solution is to support short delays in the control loop so that the spraying UAV can process the information from the sensors. We evaluate an algorithm to adjust the UAV route under changes in wind intensity and direction. Moreover, we evaluate the impact of the number of communication messages between the UAV and minimize the waste of pesticides.

Carbon dioxide emissions are the common type of gas emitted from the burning of fossil fuels. When this CO2 is released in to the atmosphere it remains there until it is absorbed in some form. 50% of CO2 emission released in to the atmosphere is absorbed by oceans. The ocean absorbs half of all carbon released into the atmosphere. CO2, like all greenhouse gases does not absorb light waves from the sun where it absorbs heat waves because they have longer wave lengths than sun light does, thus stopping the heat from being reflected into space. This is called the "greenhouse effect" and has been linked by scientists to global climate change. if we reduce CO2 emissions the air we breathe will be cleaner and that has got to be good for everyone.
