Joint Strike Fighter Term Paper Example | Topics and Well Written Essays - 1250 words

Joint Strike Fighter - Term Paper Example Most systems share common characteristics that include; maintenance of an  internal  steady state, presence of inputs, processing, output and feedback mechanisms, display emergent properties that are peculiar to the whole, and  have  boundaries defined by the system observer. Systems do not  operate  in a vacuum; they comprise of smaller units called subsystems. The subsystems  interconnected, transfer  knowledge from a system to the next. A system can only operate within its boundaries (Blanchard, Benjamin & Wolter 5). The  system  observer  defines the boundaries, and outside these boundaries lies the  environment  (Blanchard, Benjamin, and Wolter 5). The Joint Strike Fighter (JSF) program  is a  growth  and acquisition plan  intended to restore a wide array of existing  strike, fighter and land attacks for the United States and her allies. The main competitors for the program were Lockheed Martin X-35 and Boeing X-32 of which the former; Lockhee d X-35’s  prototype  won the tender. The  firm  came up with the F-35 Lighting II to replace various tactical planes such as the Canadian CF-18, British Harrier GR7 and the US F-16.  The X-35 portrayed the most  persuasive  demonstration  by taking off in less than 150 meters. ... After data  collection and conversion into appropriate  medium  for input, its processing follows; manipulation into information using  input  procedures. Output marks the end of the data processing function of the system. It communicates the information derived from the processing function to the recipient users or another  data  processing  function. System  control  is  vital  in all data processing systems (Blanchard, Benjamin & Wolter 8). System  controls  refer to a  gadget  or  set  of systems that direct,  command  or  regulate  the workings of a system. The elements of  control  include a feedback mechanism that offers descriptive and  comprehensive  information on the input,  output  and processing aspects of the system. Feedback describes a  check  within a  system  that ensures the overall achievement of system goals. It denotes a situation when the output from a  past  process  influences the recurrenc e of the same result in the  present  or future  process. Feedback mechanism  performs controls through a loopback. Positive and negative feedback mechanisms are the two broad divisions of feedback mechanism.   A positive going  wave  on the output amplifies the input signal resulting in the same output  production.  Contrastingly, a signal  inversion occurs leading to a negative going change in the output.  Interfaces are areas of intersection or interactions of different systems that exchange information or  energy. The final element of a system is the  environment. This is that  area  outside a system. A system can interact either with its environment or with not (Blanchard, Benjamin, and Walter 13). Based on their interaction with the surroundings, systems are either  open or closed systems. An open

Response to the book Essay Example | Topics and Well Written Essays - 1250 words

Response to the book - Essay Example In this article, we are going to analyze the sixth extinction portrayed in the book by Richard Leakey and Roger Lewin. Leakey is one of the most famous living Paleo-anthropologist in the world and from his experience in anthropology makes; us devote more time in trying to note the things that will hasten the next evaluation. This article will provide the pros and cons of what the two authors think will result to the sixth extinction. The book has several interesting points, which seems crucial to note, these points are also the stronghold of the book. Leakey accepts that homo sapience or the modern man is the most dominant species on earth currently. The ability to reason and have a vertebrate brain of man is the main reason why man is able to dominate other species. These are also the reasons behind the book claims that human activities are the main agents of extinction of the other species. Leakey identifies that man’s insight has led to technological improvement that have helped him expand his population at an alarming rate. The population increase and the advanced technology have led to overexploitation of the natural resources thus tampering with the ecosystem (Leakey and Lewin, 21). The book states that the historical past of man has led to killing of other species in the form of hunting for food and collections. Leakey identifies that man is destroying tropical forests that are the main habitats for millions of species either to expand their agricultural land or to build roads and cities. This will result to the extinction of these species (Leakey and Lewin, 27). This information is true basing my argument on Cantilena Island, which was known to develop a unique flora before man has destroyed it by inhabiting making it for his agricultural benefits. The unique flora is now extinct. The book states that the more man is becoming knowledgeable in science the more harmful he is becoming to other species. This is due to the
