The estimated worth of USA's GDP is estimated to be around 17.5 trillion dollars and dollar being the third currency in the world and the official currency of the US. They also manage a 5% growth every quarter. So how do they manage it? There are three main sectors that contribute to the USA's GDP. First is services that is 80% of the total GDP. The output of services in 2014 was 13,8 billion dollars witch was the nr.1 in front of European Union’s output witch was 13,4. The second contributing sector is the industry sector which provides 19% of the country’s GDP. In this area USA has fallen behind and has to accept the third position in the world’s total industry's output. First in industry’s output last year was European Union who had 4,6 billion dollar

Ticket No1 1)The characteristic is called output characteristic or volt-ampere charateristic of a Rectifier Diode. 2)Rectifier Diode. 3) A is called Anode and C is called Cathode. An Anode has positive potential and therefore collects electrons in the device. Cathode has negative potential and therefore emits electrons to anode. The symbol looks like an arrow that ponts from the anode to the cathode, and reminds that conventional current flows easily from the p side(anode) to the n side(cathode). BIASING. Forward biasing

Question 3 (10 marks) Consider the following simple mixer circuit. a) Why do we require a low-pass filter when using this mixer circuit? b) Name another disadvantage of such a mixer circuit. Solution: a) Because the mixer outputs become four (4) including the two input frequencies, the sum and the difference of them. Actually we need only the difference output frequency (Offset – Input) and the lowpass filter will help to filter aways the higher three output frequencies. b) Name another disadvantage of such a mixer circuit (page 97-98) - The mixer multiplies the wanted frequency shift but also other frequency shifts (origiral, sum, etc.). This includes noises and heating. - If the input frequency comes down and the difference frequency will increases up and may be filtered aways by the low pass filter. - The design of the mixer is complecated.

TRANSMISSION 1. A transmission or gearbox provides speed and torque conversions from a rotating power source to another device using gear ratios. The most common use is in motor vehicles, where the transmission adapts the output of the internal combustion engine to the drive wheels. Such engines need to operate at a relatively high rotational speed, which is inappropriate for starting, stopping, and slower travel. The transmission reduces the higher engine speed to the slower wheel speed, increasing torque in the process.. While a differential may also provide gear reduction, its primary purpose is to change the direction of rotation. Many manual transmissions include both synchronized

· relative ease of exit / entry · products are differentiated actual differentiation perceived differentiation Only difference from pure comp. is that the demand faced by the firm is not perfectly elastic; MR will lie below the Demand function (AR) Relaxing the characteristic of outputs from homogeneous to "differentiated products" was the basic change from the purely competitive market model. Thedifferentiation of output results in the demand faced by each seller being less than perfectly elastic. · Since there are "many sellers," many substitutes for each seller's output is implied. This suggests that the demand faced by a firm in a monopolistically competitive market is likely more elastic than in a monopoly. The elasticity obviously depends on the preferences and behavior of the buyers. The negative slope of a firm's demand function in imperfect competition results in a different

The economic theory of · monopolistic competitive markets, · oligopoly and · monopoly is used to suggest the nature of problems that may exist when firms or agents have market power and are able to distort prices away from the purely competitive optimum. The existence of market power is tied to the demand conditions the firm faces. If their product is (or can be differentiated), consumers may have a preference for one firm's output relative to others. A negatively sloped demand function (less than perfectly elastic) allows the firm to raise its price and not have its sales fall to zero. In pure competition, the firms may all try to influence market demand but individual producers do not advertise their own product. · Many agricultural markets are close to pure competition. · In many cases some producers try to differentiate their products. In pure competition, the firms' outputs are homogeneous.

object-oriented than Python The name "Ruby" was decided on during an online chat session between Matsumoto and Keiju Ishitsuka on February 24, 1993, before any code had been written for the language. History Initially two names were proposed: "Coral" and "Ruby", with the latter being chosen by Matsumoto in a later email to Ishitsuka The first public release of Ruby 0.95 was announced on Japanese domestic newsgroups on December 21, 1995 What it is look like Code Example # Output "I love Ruby" say = "I love Ruby" puts say # Output "I *LOVE* RUBY" say['love'] = "*love*" puts say.upcase # Output "I *love* Ruby" # five times 5.times { puts say } Versions Ruby 1.0 Ruby reached version 1.0 on December 25, 1996. Following the release of Ruby 1.3 in 1999 the first English language mailing list ruby-talk began, which signalled a growing interest in the language outside of Japan. In September 2000, the first English language book

Conversion costs = DL + MOH Overtime premium and idle time classified as indirect labor costs. Product cost is the sum of the costs assigned to a product for a specific purpose. Chapter 3 - Cost-Volume-Profit analysis CVP analysis examines the behavior of total revenues, total costs and operating income as changes occur in the units sold, the selling price, the variable cost per unit, or the fixed costs of a product. Breakeven point is that quantity of output sold at which total revenues equal total costs. Breakeven in units = Fixed costs/contribution margin per unit. Breakeven revenues = fixed costs/CM%. Target operating income. Qty of units required to sold = (fixed costs + target op income) / CM per unit. Revenues needed to earn = Fixed costs + target op income / CM%. Target operating income = target net income / (1-tax rate). Revenues - VE - FE = Target net income/ (1-tax rate).

reducing pollution. There are two main types of pollution control. Input control involves preventing a problem before it occurs, or at least limiting the effects the process will produce. Five major input control methods exist. People may try to restrict population growth, use less energy, improve energy efficiency, reduce waste, and move to non-polluting renewable forms of energy production. Also, automobile-produced pollution can be decreased with highly beneficial results. Output control, the opposite method, seeks to fix the problems caused by air pollution. This usually means cleaning up an area that has been damaged by pollution. Input controls are usually more effective than output controls. Output controls are also more expensive, making them less desirable to tax payers and polluting industries. Current air pollution control efforts are not all highly effective. In wealthier countries, industries are often able to shift to methods that decrease air pollution

encoding H.264 MPG2 IPB Playback type Non-linear linear Res & data 1080p 1080i 1920x1080 1440x1080 16:9 4:3 Most AVCHD cameras will claim full 1080, and some will claim 1080p output. They are all recording as a 1080i frame, and converting to 1080p when using the hdmi output. (My HDV equipment does the same, sends it to the tv as a 1080p signal over hdmi) The resolution is 1920x1080, so technically this would be a slightly sharper picture than the 1440x1080 that HDV records. My JVC camera has 4 compression settings. 5meg, 12 meg, 15 meg and a whopping 24 meg. The 3 lower bit rates are directly compatable with the AVCHD standard for optical disks, so
