...space with zero atoms consist of stones. 5. All empty space does not consist of stones. 6. Therefore, stones do not exist. To go even further, I can add another step in order to conclude that ordinary objects do not exist. The additional step would be that if ordinary objects exist, then stones must also exist. Therefore, ordinary objects do not exist. First we must see what objects exists and what objects occupy a position in space and time. Objects in the universe include planets, people, atoms, chairs, and the sun. They are all made out of parts and they are all composite objects. In order to explain the idea of composition we can say that the x’s compose a composite object if and only if the x’s, taken together have a function that none of them have separately, the x’s are physically bonded, and the x’s are inseparable. Nihilism supports Unger’s idea that stones do not exist because nihilism supports the idea that composition never occurs and therefore,...

...Samantha Poteet ENGWR 480 Professor Kiefer 31 October 2013 Little is known about Jakob von Uexküll, the author of A Foray into the Worlds of Animals and Humans: With a Theory of Meaning, other than his credentials and contributions. Uexküll studied zoology at the University of Tartu, known as Dorpat at the time, in Estonia from 1884 to 1889 (SUNY Press; Jakob von Uexküll Centre). Later Uexküll worked at the Institute of Physiology of the University of Heidelberg and at the Zoological Center in Naples, focusing on the behavior and interaction of living beings (SUNY Press; Jakob von Uexküll Centre). His written works were dedicated to the question of how living beings subjectively perceive their environment and how their perception determines their behavior, which is a dominant theme throughout A Foray in the Worlds (Jakob von Uexküll Centre). Uexküll argues that the spider builds its web before it has ever met a physical fly, therefore it is a representation of the spider’s primal image of the fly (159). Uexküll’s claim depends on three assumptions: (1) the fly is the prey of the spider, (2) the spider has a primal image of the fly, and (3) the web is the end product of the spider’s primal image. Though Uexküll’s claim may well have some merit, he presents an incomplete argument as his assumptions are insufficient and based solely on the evidence he offers, his argument cannot be accepted as valid. Uexküll’s first assumption is correct but also insufficient as it does...

It signifies what the emblem presently stands for. it is a assembly of convictions order about a exact brand. In short, it is not anything but the consumers’ perception about the product. it is the kind inside which a particular emblem is positioned in the market. Emblem likeness expresses emotional worth and not just a mental representation. Emblem image is not anything but aide degree organization’s feature. it is aide degree accumulation of contact and fact by individuals external to an association. It ought to focus aide degree organization’s operation and dream to any or all. The major parts of positive emblem image are- exclusive emblem reflective organization’s likeness, saying recounting organization’s business in short and emblem identifier carrying the key values. Brand image is that the overall impression in consumers’ mind that's formed from all sources. shoppers develop various associations with the brand. supported these associations, they form brand image. an image is made about the brand on the idea of subjective perceptions of associations bundle that the shoppers have about the brand. Volvo is associated with safety. Toyota is associated with reliableness Image of a brand has a great impact on consumer’s preferences, because it’s the current view of a product according to the...

...Tom Gause 4/22/13 Unit 4 research paper: Port Expander “A port expander is a hardware device designed to utilize more than one device on a single port at one time.” In layman’s terms, this can also be called a “splitter.” There are many different types of port expanders, but they can be narrowed down to two major groups; internal, and external. They are generic devices that will function no matter where they’re installed. Internal port expanders attach to your motherboard, and the user will only see the back plate. From a hardware standpoint, there is no difference in the type of computer. If the card fits, it will work. The first image in the appendix is an example of a port expander. External port expanders are not attached to the motherboard. They plug into a slot on the computer, and allow multiple devices to attach to that slot. The second image in the appendix is an example of an external port expander. One of the biggest advantages to using a port splitter is during multitasking. For example, most user interface devices are USB devices, mice, keyboards, printers, and even cell phone chargers can all be plugged into a USB slot. Therefore, the more ports you have, the more peripheral attachments you can use. On the other hand, with so many devices plugged into a single port the power source could get overwhelmed. Without the proper safety measures, an overloaded power source could “burn out” and cease functioning. Appendix Image 1: Internal Port Expander ...

...FOCAL LENGTH OF A LENS AIM: The aim of this experiment is to determine the focal length (f) of a convex lens by two methods. YOU WILL NEED: A 10 cm focal length bi-convex lens, lens holder, screen (a wooden block with a white painted side is ideal), ruler, light source (mounted clear bulb), power supply suitable for the lamp. An optical bench is ideal if one is available. WHAT TO DO: (a) Minimum distance method Set up the lamp, lens and screen so that a clear image of the lamp filament is formed on the screen. Measure the object and image distances (u and v). Repeat the experiment for a series of values over the range u+v = 45 cm to 100 cm. ANALYSIS AND CONCLUSION: Plot a graph of u+v against u. The minimum point on the graph is at a point u+v = 4f, u = 2f (b) Two position method Set up the lamp, lens and screen 0.6m apart. Find the TWO positions where a clearly focused image of the lamp may be obtained. (one of these will give a large image and the other a small image). Measure the separation of lamp and screen (d) and the distance between the two positions of the lens (a) Repeat the procedure for other values of d between 0. 5m and 1m ANALYSIS AND CONCLUSION: The focal length of the lens may be calculated from the formula: f = [d2 – a2]/4d ----------------------- a v2 d u1 2...

...failure of an earlier ERP project, a new project called BMIS was envisioned. Highlights of BMIS project: • Vision: Functional councils of Methods, quality, Work and material planning, procurement created for role and direction determination. • Team: Best employees from various functions along with BTS (Business transformation services) with an employee to consultant ratio of 10:1. • Implementation strategy: Progressive and phased approach, beginning with Mirabel plant near Montréal. • Procurement function restructure: improvement of inventory visibility and anticipated substantial savings in product costs($ 22 million) and procurement overhead($7.1 million) • First Rollout challenges: lack of documentation, system functionality, substandard training material, tight training schedules and lack of role clarity during training. • Go Live: Power users and super users supported the move initially. Later on, if support staff was not able to resolve issues, the legacy systems were used to conduct business. • Stabilization: The project did not disrupt production schedules and the company delivered one more plane than planned during the period. There was overall saving of $ 1.2 billion. Procurement functions changed even though lots of others were de-scoped. • Next milestones: Two additional programs were implemented eventually with better rate of success at...

The modulo function (a mod n or a modulo n) maps every positive integer number to the remainder of the division of a/n. For example, the expression 22 mod 5 would evaluate to 2 since 22 divided by 5 is 4 with a remainder of 2. The expression 10 mod 5 would resolve to 0 since 10 is divisible by 5 and there is not a remainder. a. If n is fixed as 5, is this function one-to-one? (5 points) F(n mod 5) is not one-to-one function, because f(n mod 5)= between 0 and 4. It means that we have the same image of F for different n (integer). b.

...Another Facebook fan page I would like to talk about is the fan page of Groupon Hong Kong. I think it cannot effectively act as an advertising tool and build relation with audiences and visitors. First, the fan page cannot efficiently build awareness among target audiences. The fan page of Groupon has 7 years of development, it was set up in 2007 and already got 11,892,526 likes on its fan page. It seems that the fan page of Groupon is popular, but that’s is not the truth. After searching the website of Groupon, the likes on the fan page was gained by the $50 coupon provide by the company, which can get by liking the fan page on Facebook. However, Groupon did not make good use of these likes and audience, by taking a look of the status and posts on the fan page, nearly 99% of them have no comments left by audience, also, the posts only got 10-20 likes each, which is lesser than 0.000001% of totally followers of the page, more importantly, the likes keep decreasing from 2012. Although, the followers of the fan page are mostly between 25-34, which are the heaviest users of Groupon, but the posts and information on the fan page are not welcomed by them according to the number of likes the posts got. Second, the content of Groupon’s fan page failed to build up a positive image among audiences and followers.
