Optical Disc Storage – Computer Science Essay (100 Level Course) Free Online Research Papers Optical Disc Storage Computer Science Essay (100 Level Course) An optical disc is a storage media consisting of a flat, round, portable disc made of metal, plastic, and lacquer. Optic disc are written and read by a laxer. Different formats of optical disc are CD-ROM, CD-R, CD-RW, DVD-ROM, DVD-R, DVD+R, DVD-RW, DVD+RW, and DVD+RAM. Optical drive(s) usually are a standard feature on today’s personal computers. Users can read but not write or erase a CD-ROM, which stands for compact disc read-only memory. Users record their own items such as text, graphics, and audio on a CD-R, (compact disc recordable). You can write on a part of the disc at one time and another part at a later time. Oce recorded, a CD-R can be read from as many times as necessary. However, each part of a CD-R can be written only one time. The disc’s contents cannot be erased. You need a CD recorded or a CD-R drive to write on a CD-R. On the other hand, a CD-RW, a compact disc-rewritable, is an erasable disc you can write and rewrite multiple times. Reliability of the disc tends to drop, however, with each successive rewrite. To write on a CD-RW disc, you must have CD-RW software and a CD-RW drive (Manzanera Brautigam 14-20). A DVD-ROM is extremely high-capacity optical disc that stores 4.7 GB to 17 GB. DVD-ROM means digital versatile disc-ROM or digital video disc-ROM. The goal of DVD’s is to meet the needs of home entertainment, computer usage, and business data and information storage with a single medium. DVDs store huge databases, music, complexes, software, and movies. You must have a DVD-ROM drive or DVD player to read a DVD-ROM. Newer DVD-ROM deives also can read audio CD’s, CD-ROMs, CD-Rs, and CD-RWs (High Capacity Storage Media). To write on DVD-recordable or DVD-rewriteable disc, you must have the proper type of drive. DVD-R and DVD+R are competing DVD-recordable formats. Each has 4.7 GB of storage capacity. Both allow users to write on the disc once and read it many times. DVD-RW, DVD+RW, and DVD-RAM are competing rewritable DVD formats. DVD-RW and DVD+RAM allow users to erase and record more than 1,000 times. DVD+RAM allows users to erase and record on a DVD+RAM disc more than 100,000 times (Guzman Padilla). Encarta Dictionary. English (North America). 14 Sept. 2005. Microsoft Word Online Research.

Regenerative Braking

Regenerative Braking If you drive in an urban area, you probably realize youre continually stopping and starting on the road. Its a big waste of time, but you might not also realize that its a huge waste of energy. Making a car move forward requires needs a large input of power, and every time you step on the brakes, all the energy you built up dissipates. According to the rules of physics, energy cannot be destroyed. That means when your car slows down, the kinetic energy that was moving it forward has to go somewhere its lost in the brake pads and released as heat.  But what if you could store up this energy and use it when you next begin to accelerate? Thats the basic principle behind regenerative brakes, which are widely used in electric cars and trains. Definition Regenerative braking is a system in which the electric motor that normally drives a hybrid or pure electric vehicle is essentially operated in reverse (electrically) during braking or coasting. Instead of consuming energy to propel a vehicle, the motor acts as a generator that charges the onboard batteries with electrical energy that would normally be lost as heat through traditional mechanical friction brakes. As the motor â€Å"acts in reverse,† it generates electricity. The accompanying friction (electrical resistance) assists the normal brake pads in overcoming inertia and helps slow the vehicle. Traditional vs. Regenerative In a tr ­aditional braking system, brake pads create friction with the brake rotors which stop or slow the car. Friction is also produced between the wheels and the roads surface. Both create heat from the cars kinetic energy. However, with regenerative brakes, the system that drives the vehicle does most of the braking. When you depress the brake pedal on a hybrid or electric car, these brakes shift the automobiles electric motor into reverse which makes it run backward, in turn slowing the cars wheels. While running backward, the motor also acts as an electric generator by creating electricity thats delivered into the cars batteries. Best Situations Regenerative brakes are more effective at certain speeds. They are actually most useful in stop-and-go situations. Hybrids and electric cars also do have friction brakes that act as a type of back-up system in scenarios where regenerative braking cant supply enough power to stop. In these cases, drivers should aware that the brake pedal could respond differently to pressure. It will sometimes depress farther towards the floor than usual a feeling that can momentarily cause drivers to panic. Hydraulic Regenerative Braking Ford Motor Company and the Eaton Corporation have developed a newer type of regenerative braking system called Hydraulic Power Assist or HPA. When the driver depresses the brake with HPA, the cars kinetic energy powers a reversible pump which directs hydraulic fluid from a low-pressure accumulator (a type of storage tank) and into a high-pressure accumulator. Estimates for HPA indicate it could store 80 percent of the movements lost by deceleration and use it to move the car forward.

Tax law Case Study Example | Topics and Well Written Essays - 1000 words

Tax law - Case Study Example Jones to change Smithon from a fiscal year end to calendar year end and convert it to an S corporation. You asked that I give you definitive answers regarding the outright purchase of Smithon stock, as well as the potential merger or acquisition of Smithon by Johnson Services. Of these two main issues there are several minor points that need addressed? I will break each section down and answer those questions specifically, definitively responding for each. To be addressed first is, 1. the outright purchase of Smithon stock a. Should you purchase the stock of Smith outright, leaving Smithon intact? What about issuing debt in your Johnson Services company to pay for the Smith Company-would that raise debt to equity issues? It is sometimes better to purchase the stock of Smithon outright, however, in looking at the potential benefit of using the credit power of Johnson Services and issuing corporate bonds you would free up the cash necessary to make changes if they become a need. There is also the added benefit of the debt tax shield. IRC 514 expands on debt-finance income when one uses income gained by borrowing against investment property. (IRC 514) Obviously, an issue is the potential problem with debt to equity, however, given the losses posted by Johnson Services recently it seems expedient to explore corporate bonds or additional share opportunities and use the cash available to re-tool Smithon. By using the available debt tax shield, you stand to benefit in numerous ways from using Johnson Services as a backer for purchasing Smithon. One potential disadvantage is that issuing debt can increase the risk of bankruptcy. (Damodaran 9) b. Should I convert Smithon to an S corporation and change the fiscal year end to a calendar year end? c. What potential income tax ramifications exist for me if I purchase the stock of Smithon and convert it to an S corporation? If you use the credit available from Johnson to purchase Smithon it would be beneficial to retain the C status of that corporation and take full advantage of the corporate tax benefits resulting. However, if you decide to use cash to purchase Smithon and end up with a large personal liability then converting it to S status would become more beneficial. Due to increased taxes on a personal level with the utilization of â€Å"mean testing† it would seem more personally beneficial to retain the C status of the corporation and keep the potential income from that business out of the data included in the â€Å"mean testing.† The income of an S corporation is generally taxed to the shareholders of that corporation rather than the corporation itself. (IRS form 2553 1) As for changing from a fiscal to calendar year end, this would result in filing a short tax year, and additional expenses administratively with no real net benefit. d. Should I merge Johnson Services and Smithon? What type of merger or acquisition would be best (i.e., A type, etc.)? Because there are no available data sets as to the similarities between Smithon Widgets manufacturing and Johnson Services it would be necessary to further explore the ability for both companies to function together. If a merger becomes an option and is pursued successfully the most effective merger type given the information currently available would be the conglomeration merger. This type of merger is between two businesses that are involved in totally unrelated activities. There is the

Untitled (Society Portrait) Essay Example | Topics and Well Written Essays - 500 words

Untitled (Society Portrait) - Essay Example On the first gaze at the portrait, it seems that the lady definitely belongs to the aristocratic segment of the society. Lying half–seated on a couch, the lady seems a bit pensive in mood. The color of her skin, hair and eyes indicate that she is European by race. Interestingly, only very few colors are used in the portrait. Yellow, white, grey and shades of brown both deep and light are schematically used in the picture. At the same time, one can argue as that these coolers are building a theme for the portrait of the anonymous lady as well. Very interestingly, the background colors are very much different and the painter uses light and dark shades of blue along with tinge and shades of brown over it which is quite well synchronized and chosen deliberately as the color scheme of the portrait is on the lighter and drab side. Use of light is done meticulously throughout the portrait and the lines are so fine that nobody will ever find in determining the mood and gesture of the lady. The couch on the other hand is casted with the hue of red color and here too the use of brown both light and dark shades have been well organized keeping in mind the actual color scheme of the portrait. Taking a gaze at the socio-cultural aspect of the society portrait apart from its technical side, it can be well asserted that the hair style and the kind of wardrobe, the lady is putting up indicates a time frame of early half of the twentieth century. During that time, butterfly sleeves and use of shrugs, stoles and veils were very common. The lady is also putting up a necklace made of some yellow beads; the choice of simple yet exquisite jewelry in terms of both the necklace and the ear-ring and wristlet on the left hand is showing a mark of classy style. The lady is probably holding her bag or a veil black in color and very interestingly the side of the couch is having dark brown and black hues which is posited parallel to the lady’s black

Org behavior Assignment Example | Topics and Well Written Essays - 500 words - 3

Org behavior - Assignment Example Less-sophisticated technological systems may allow for a flatter, horizontal structure that provides employees with more autonomous function. Employees in the organization may not have the tacit knowledge that some experts in the organization hold and do not always have access to face-to-face interventions with knowledge experts. Therefore, they become dependent on data from technology systems in order to guarantee effective knowledge transfer, such as using enterprise resource planning software to gain valuable real-time data occurring in the organization. For instance, customer service can access software to determine current inventory levels in order to ensure order fulfillment. This knowledge source (CSR) now holds knowledge no other individual in the organization carries from external sources. They can take this technology-driven knowledge to consult with production to temporarily double output in order to meet future demand. Technology maintains â€Å"a crucial role in enabling knowledge-centric practices† (Dataware Technologies, 2008, p.2). Having an understanding of the external market is one competency providing competitive advantage. Many organizations rely on differentiation strategies in order to build a brand that stands out uniquely from competitors. In order to create a more effective service model or product concept, the organization needs to conduct market research on consumer attitudes, behaviors, and needs to align operations and service to deliver these outputs. Another core competency is creating a unified organizational culture, using transformational leadership to gain commitment, loyalty and employee satisfaction (Fairholm, 2009). Human capital development in terms of coaching and training using elements of transformational style can give employees more transferrable knowledge within the organization and attitude that focuses on service excellence and total quality management of outputs.
