Presented in thousands of Canadian dollars, except per share amounts** The recent economic downturn has served to demonstrate the vulnerability of Westjet global economy and in particular, the tenuous financial thread by which a considerable number of airlines around the world operate. In Canada, there continues to be an uneven playing field that serves to give Canadian operators a disadvantage. This has resulted in a considerable increase in the number of Canadian passengers who cross the Canada/U
around winglets is complicated, and winglets have to be carefully designed and tested for each aircraft.” (How Things Work: Winglets). The invention of the winglet allows a reduction in drag acting upon the aircraft by converting the airflow at a wingtip into a forward force, rather than an upward force. The size, shape and angle of which a winglet is mounted to the wing, depends on the aircraft type and size. A winglet improves the overall performance of the aircraft and is beneficial to the aviation
Wing tip devices are simply designed airfoils that improve a wing’s lift-to-drag ratio. Through this combination of increased lift and reduced drag, an aircraft can fly more efficiently with the net result being more economical fuel burn. Wing tip devices were first created in 1897, a British engineer named Frederick Lancaster created wing tip devices called wing end plates to improve the aerodynamic characteristics of the airfoils he designed (Air force Studies Board, 2007). Through the years, designers
The Boeing 737 is one of the most popular aircraft ever produced. Over 7700 in all variants have been produced, with an additional 11,275 aircraft on order. This makes the 737 the most popular jetliner to date. The 737 has a wide variety of uses, and still remains extremely popular and under high demand. Because it is such a widely mass produced aircraft, it is also a target for constant aerodynamic improvements. Boeing has looked at everything from the design of the anti-collision lights,
The Ignition Interlock for Drunk Drivers The ignition interlock is a high tech system that eveuates the persons BAC (Blood Alcohol Content) to see if the individual has been drinking. The device works like a normal Breathalyzer. The device is mounted on the dashboard and in order for the car to start the individual must blow into the machine. The machine then evaluates the persons BAC and if that person shows no sign of alcohol use the car will start. If the results come back saying he has consumed
developed throughout the years and now they are able to be on electronic devices. Reading e-books does not have to be at a computer. Almost all devices used for school can have online books downloaded on them. People can read e-books on small devices like an Ipad or a kindle. It just depends on what device it is downloaded on (“What…” 1). Students can download their online textbooks on any device they want as long as the device supports the e-book being downloaded. While some teachers think online
and describe how those devices could support a student with a disability in the classroom. Assistive technology is used to improve functional capabilities for an individual. With that being said there is a wide range of different technologies that could be used to assist an individual. Examples of AT found on (Page 1: Assistive Technology Devices) consist of brail books, book scanners, magnifiers, grabbers, pencil grips, and highlighters. It is obvious that the range of devices vary in helping a variety
Designing, Making and Testing a Sundial Introduction: The sundial is the oldest know device for measuring time. The first confirmed uses of it where by the Babylonians in around 2000BC. However it is safe to say that shadows have been used as a rough measure of time ever since primitive man discovered that as the day progresses the shadows of trees and rocks get shorter and then longer again. The sundials used by the Babylonians were hollow half spheres, set with edges flat and with
Next-Generation home we will find a network of appliances that are linked to the Web through various non-traditional devices such as; PDA's, TV's, ovens, and phones. The Next-Generation home receives information continuously and effortlessly which makes it simple to receive updates to an electronic phone book or downloading e-mails from the office to a PDA. With the non-traditional devices linked to the Web, this makes the PC no longer the sole connection point within the network (The Network Home, 2006)
easier as I found that a lot of the information to be on the HSE website. Overall I believe that I have covered all of the assignment that is possible in light of not being able to cover section 4 hence the reason that I have expanded the safety devices section somewhat. Bibliography Below are a list of some of the key web sites and documents I used during my research for this assignment.

utilize the imagery of a photograph as a communication device however, upon closer examination they differ markedly in the approach each poet takes in utilizing this same device. The similarities between these two poems are immediately obvious to the reader; both poems are written by female poets, both poems have the poet as the speaker, both poems describe how the poet feels about herself, and both poems utilize the photograph as a device to convey their message to the reader. Less obvious,
Symbolism and Devices in The Open Boat The struggle for survival by mankind can be found in many different settings. It can be seen on a battlefield, a hospital room or at sea as related in “The Open Boat”, written in 1897 by Stephen Crane. The story is based on his actual experiences when he survived the sinking of the SS Commodore off the coast of Florida in early 1897. “The Open Boat” is Stephen Crane’s account of life and death at sea told through the use of themes and devices to emphasize
play are codependent and need to have a symbiotic relationship to ensure their mutual survival. A lack of characters in the play would make very difficult reading and perhaps more difficult viewing. A lack of characters would necessitate some other device to be used and a substitute has not been found that replaces the role characters play in a play. An example from the play is when Oedipus was speaking to Teiresias: "I did not know then you would talk like a foolor it would have been long before
than the once popular (now referred to as) dinosaur monitors. With companies like Apple and Dell constantly coming up with new devices it’s hard for the buyer to purchase with one is right for them. There are many things to consider when you’re shopping for a new tool to access today’s newest technology and the buyer must then ask his/herself “what am I going to use my device for?” In recent years the tablet was designed, and now it is very well known. The tablet challenged the traditional laptops that
Dostoevsky’s Crime and Punishment and Ibsen’s A Doll’s House have one main thing in common: crime. In A Doll’s House Ibsen highlights the injustice of the law, and the restrictions it puts upon individuals in society, while Dostoevsky uses it to show freedom through law and the need for individuals to abide by it. Both the novel and the play introduce crime to the plot at the very beginning of the work. In A Doll’s House Mrs. Linde enters and Nora tells her about “it” but immediately says that “Torvald
Assistive Listening Devices Several assistive listening devices can improve the communication ability of deaf children. According to IDEA, every child with a disability is entitled to have access to assistive technology (California Department of Education, 2004). The California Department of Education (2004) outlines IDEA’s definition of an assistive technology device. It explains that this device consists of “any item, piece of equipment or product system…that is used to increase, maintain
were used solely to transport freight in factories and ore in mines. Unfortunately, these elevators required a safety device to restrain the elevator from dropping if it’s supporting cable broke, and this had not been invented yet. Eventually, this necessity was discerned and acted upon. In 1852, Elisha Graves Otis designed the first safety contrivance for elevators. This device was a system involving spring-operated cams that affianced the guide rails in the elevator shaft when the cable broke.
mounting it as a device. Containers vastly decrease the tedious task of individually encrypting files since you simply move your files into the mount point and then unmount and they nicely encrypted. First, you need to create a blank file using the dd command. dd if=/dev/urandom of=crypto.img bs=1M count=50 - The first parameter uses the /dev/urandom device to create the file with random data to make it more difficult to distinguish between free space and encrypted data. The /dev/zero device can be used
some new technology coming out, and taking over the lives of young adolescents. Technology is more commonly used among teens than any other age range. Technology has captivated the minds of young adolescents in a way to where they rely more on their devices for education and social life rather than themselves. Using technology for educational purposes and social life has left negative effects among teens. Technology does improve learning skills and makes learning more fun but some kids are using their
A Mesh topology is a style of connecting computers in a network in a fashion where every link has a redundant path. A mesh topology is also known as a self healing network in that if a segment of the network fails for what ever reason then the data can still be transmitted across another linked path. This would include possibly hoping across a few extra network segments to reach the destination but it would be able to do it. This redundancy of course comes with a price for the extra pathing that
