Commercial Use of Unmanned Aerial Vehicles Term Paper

Commercial Use of Unmanned Aerial Vehicles - Term Paper Example Both ideas failed however, but the concept lived on. In the 1960s, the US started developing drones for spying and reconnaissance missions and extensively used them in the Vietnam War (UFL, 2011). With the development of artificial intelligence, today, UAV are a regular feature in military missions and are extensively used for various operations from reconnaissance to defensive and offensive missions. With increasing reliability of the UAVs, they have also now been identified for various commercial uses. This paper discusses these commercial applications where UAVs are increasing finding use. 2. Commercial uses of UAVs As the UAVs are free from human limits of fatigue and endurance, they can perform several functions very efficiently and in areas where it is not possible or too costly/risky to reach in a piloted aircraft. With improvements in technology, efforts to reduce the operating costs of UAVs, and by complimenting the UAVs with other advanced technology and devices, several ar eas of commercial applications have been identified for UAVs where they can prove to be not only more cost effective but also much more efficient than conventional methods used today to do those tasks. The following sub-sections describe each of these commercial applications. 1. 2. 2.1. ... ay, this work is done by men walking in the field, using manned small aircrafts, and using other farm equipments like tractors with a sprayer fitted at the back. These methods are often time consuming and using small aircrafts is costly. Also, in order to reduce drift on the sprayed materials, aircrafts must be flown very low. Since, fields are generally surrounded by obstacles like trees, buildings, telephone and electricity lines, pilots must be very careful. With a UAV, this task can be accomplished with much less hassles. Estimates suggest that UAVs take 1/15th the time to complete the task as compared to other conventional means (Wong, 2001) and it costs 1/10th the hourly rate of a manned helicopter (Hanlon, 2004). Figure 1: UAV helicopter being used for crop dusting Source: Gizmodo, 2006 Crop monitoring refers to monitoring the health of crops in the fields. With sensors and high resolution image processors on board the UAVs, farmers can remotely monitor the crops and take time ly actions to save the crops. Also, farmers and governments can use it for making crop yield forecasts and assessment of damage due to external factors like flooding, pests, and draught. Further, color images from UAVs can be useful for mapping invasive weed outbreaks and for revealing irrigation and fertilization irregularities in the vast farmlands. Another example of regular use of UAVs in crop monitoring is at Vineyards. Current frost detection techniques do not provide accurate and consistent data for temperature across the entire farmland. UAVs with real-time thermal imaging could provide an excellent solution to this problem. Another area of application in agriculture industry is monitoring soil and moisture. One of the most important aspects for maximizing the crop yield is to know

American fast food in China - Essay Example However, McDonald's is the easily recognizable Fast-food brand in China. KFC has got the largest chains of fast-food restaurants in China with approximately 4000 fast-food restaurants. These restaurants are both domestic and foreign brands. The founder of this fried chicken chain of restaurant, Colonel Sanders, is one of the most recognized American faces among the Chinese. There have been emerging scandals that have been aired in relation to the excessive levels of antibiotics that have been used by American fast-food restaurants in China. Brands like KFC and McDonalds have been held responsible for claims that they have led to an epidemic of obesity in China. This weight gain can also be linked to the Chinese breakneck development. Other developing nations are rapidly undergoing an economic transition but China seems to be dragging behind as a result of a large majority of people gaining weight thus cannot manage to work properly to build the nation.The number of obese people in Ch ina grew from 18 million to 100 million in 2005 and 2009, whereas its national GDP doubled at that same period. However, it is quite surprising that even though China is known to have a population that eats a lot, the situation tends to be worse because China is considered to have another problem of having a malnourished nation. Other nations that experience the same are Vietnam and India. Diseases that are caused by consumption of excess sugar and fat have become popular in China. These diseases include high blood pressure, heart diseases, and Type 2 diabetes. An estimate of 9.7 per cent of Chinese country have diabetes especially, Type 2. This data is close to the findings of America which are 11 per cent of the total population. These findings were from a study conducted by New England Journal of Medicine. There are various reasons which have made the contribution towards the realization of massive profits by American fast food restaurants in China. This paper concentrates on the reasons as to why these changes have occurred and why they happen as they do. A lot of research has been done in an effort to investigate this phenomenon and Smith (2006) notes that localization of meals is what has contributed to the attraction of native customers in the foreign country. Localization of mea
