One of the biggest disadvantages is not being able to make connections as easy as the copper. Fiber optic cables have a core as fine as a human hair, making it extremely difficult to splice. Copper cables are obviously not going to be around forever with the fiber optics being so futuristic, but they still have advantages over the fiber. Copper is very easy to work with. When making connections it is so much easier to splice the copper cable than it would be for the fiber.
A slower process than MIG, it produces a more precise weld and can be used at lower amperages for thinner metal and can be used on exotic metals. TIG does require quite a bit more time than MIG to learn. It is similar in technique to gas welding. TIG can be used with pure helium or argon as an inert shielding gas to protect the weld pool from the atmosphere. (Nitrogen, hydrogen, oxygen, carbon dioxide, and other elements cause weld defects if introduced to the weld pool.)
The disadvantages of frequency modulation are that the components to demodulate are much more expensive and complicated, some modes have higher data spectral efficiency, and there could be some distortion because the sidebands extend to each side infinitely. Phase Modulation Phase modulation is related to frequency modulation except the advantage to phase modulation is that it has less interference from static and the
The fabrication phases and the assembly and test phase consist of their own procedures. Nowadays manufacturing process becomes more and more technologically diverse and intense. It results in a decrease in a direct labor percentage of total manufacturing cost. Management considered that an inaccuracy of GEI’s standard cost system caused a poor financial performance. The company need find a better cost system which could truly track costs and identify which of products were profitable and which were not.
3) What are the factors that lead to or impede successful ABC implementation (i.e., individual, organizational, technological, external) and which factors were present in the case of Universal? Do these success factors tend to be more behavioral or technical in nature? Universal Electronics’s standard costing system was basically allocating large pieces of overhead to production processes, and burying essential elements of manufacturing costs. These methods not only created incorrect costs, but also they did not provide the costing accuracy or level of detail needed in that competitive business environment. There are several factors, or lack thereof, that can have a direct impact into a successful or unsuccessful ABC implementation, and these can be categorize as follows: * Individual Factors: * There should be individual(s) with expert knowledge of ABC in order to successfully implement this system into a company.
By designing computer systems that can be added on to with new technology can be initially more expensive than the traditional design way of building a system that will be obsolete because it does not have room and provisions for future new technology hardware and or new technology hardware compatibility issues. The new design approach may be more expensive when first created, but because this new system can be upgraded and evolve, will save the company money in the long run as it will have a longer projected life cycle. The other challenge the IT department will have is at the software level such as, operating systems and computer system applications compatibility issues. Because not all company’s and businesses IT Systems are the same or have not been upgraded at the same time. Operating systems in some cases such as Microsoft Windows XP, VISTA, and Windows 7 are still in use are an area of concern.
One of the advantages of a ring topology is the installation and troubleshooting. A ring topology also has the ability to handle heavier networks better than some other setups. One of the disadvantages
In this way, Steelco could not only make use of the excess plate capacity, but also set a competitive advantage in larger size wide-flange beams. Thus, Steelco could break the monopoly position of USX in 24 inches or above segment market. In the long run, these larger sizes might offer a significant breakthrough for the construction industry. 1.3 Market reaction and possible reasons However, the market reaction was disappointing when the new products are brought in. The reasons are as follows.
Behavioral constraints Behavioral constraints are a negative form of action control. They make it impossible, or at least more difficult, for employees to do things that should not be done. The constraints can be applied physically or administratively. Most companies use multiple forms of physical constraints, including locks on desks, computer passwords, and limits on access to areas where valuable inventories and sensitive information are kept. Some behavioral constraint devices are technically sophisticated and often expensive, such as magnetic identification card readers and fingerprint or eyeball pattern readers.
MAUs are easy to install and troubleshoot. However, MAUs are more expensive than hubs and switches. In addition, compatible hardware, cables, and NICs are also expensive and not readily available (Ciccarelli, et al 2013). The maximum amount of bandwidth a MAU can support is 16Mbps (Ciccarelli, et al 2013). MAUs can only operate at 4Mbps or 16Mbps which means that you cannot connect a 4Mbps MAU to a 16Mbps MAU (Ciccarelli, et al
