Finally, the evaluation section is where you summarize the strengths and weaknesses of your design and describe recommendations for future work. The evaluation section should have the following subsections using the suggested labels for each subsection: Overview In this section, you provide an overview of your approach and an overview of the test plan for evaluating the design. Here is where you state whether the approach was by experimental testing of a prototype, computer simulation, hand calculations, user testing or a combination of these methods. In a new paragraph, include a summary table of the key design requirements from the problem statement section. A suggested structure for the table is that column one states the requirement, column two has the target value and column 3 has test method used to evaluate the requirement. The details come later in the evaluation section, so keep this summary short.

information technology, and biorobotics. Patho-biotechnology describes the exploitation of pathogens or pathogen derived compounds for beneficial effect. Information technology -Information technology (IT), as defined by the Information Technology Association of America (ITAA), is "the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware." IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information. Today, the term information technology has ballooned to encompass many aspects of computing and technology, and the term has become very recognizable. The information technology umbrella can be quite large, covering many fields. IT professionals perform a variety of duties that range from installing applications to designing complex computer networks and information databases
Special-purpose Computers Manufactured to do a predetermined task or set of tasks. Digital Computers One that functions in discretely varying quantities. Produces or gives results that are also discretely varying. Analog Computers One that functions in continuously varying quantities. Produces or gives results that are also continuously varying. The General-Purpose Digital Computer Accepts information of many kinds. Changes it in a way that is controlled by humans. Presents results in a way usable by humans. Alan Turingi idee, milline võiks olla lihtne universaalne arvuti: suudaks arvutada/järeldada kõike!! Turingi tees: kõike, mida üldse saab mingi masinaga arvutada/järeldada, saab ka Turingi masinaga arvutada. Mida saab üldse mehaaniliselt arvutada/järeldada? Selgub, et kõiki täpselt

sometimes they can only be used once. Railgun durability: To date railgun demonstrations, while impressive, have not demonstrated an ability to fire multiple full power shots from the same set of rails. Tolerating launch accelerations of tens of thousands of g's, extreme pressures and mega ampere currents over this sort of duty cycle is currently beyond the state of the art. 11 Projectile guidance: A future capability critical to fielding a real railgun weapon is developing a robust guidance package that will allow the railgun to fire at distant targets or to hit incoming missiles. Developing such a package is a real challenge. According to The Navy's RFP Navy SBIR 2012.1 - Topic N121-102 the following is required: The package must fit within the mass of less than 2kg, outer diameter less than 40
Jamaica has a wide variety of industrial and commercial activities. The aviation industry is able to perform most routine aircraft maintenance, except for heavy structural repairs. There is a considerable amount of technical support for transport and agricultural aviation. Jamaica has a considerable amount of industrial engineering, light manufacturing, including metal fabrication, metal roofing, and furniture manufacturing. Food and beverage processing, glassware manufacturing, computer software and data processing, printing and publishing, insurance underwriting, music and recording, and advanced education activities can be found in the larger urban areas. The Jamaican construction industry is entirely self-sufficient, with professional technical standards and guidance. Since the first quarter of 2006, the economy of Jamaica has undergone a period of staunch growth. With inflation for the 2006 calendar year down to 6.0% and unemployment down to 8
