Operations Management - Essay Example SPC is also found to provide a new insight of relationships between quality and productivity performance measures (Colledani and Tolio, 2009). In addition, by the use of statistical methods, SPC can be a powerful technique for monitoring, managing and analyzing and improving process performance (Chen et al., 2008). Knowing these significant views of SPC and its linked benefits primarily in a manufacturing industry is a foundation of the idea that perhaps, this technique can also be employed even in way beyond the bound of manufacturing industries, especially if those industries have the intention to enhance or improve quality, cost, productivity, human resource management, and customer relationship. Regarding this, the work at hand builds a report substantiating the idea that SPC can also be useful in service industries. There are major claims that are presented in this report that are backed by existing research studies that have important link with the importance of SPC in the serv ice industries. ... Undeniably, services have become integral components of the industrial goods, as manufacturing goods and providing services have come in a package as a notable trend (Johansson and Olhager, 2006). Johansson and Olhager found that the common ground between manufacturing and service operations can be observed within the need to analyse volume, variety, and process issues. In other words, one important connection between service and manufacturing activities is found within the actual operation. The actual operation in the real world is wider in its scope, but this does not deny the idea that every firm operation may it for manufacturing or service industry must require a certain process. To consider productivity, the issue of volume or variety cannot be overlooked. In fact, both service and manufacturing activities have certain target goals to obtain certain level of productivity output. However, this does not stop with the consideration of productivity alone. Profitability is another c oncern of every firm that is either a part of the manufacturing or service industry. In the case of firms manufacturing or selling goods, after-sales services are found to affect company’s profitability, customer retention and product development (Saccani et al., 2007). This finding reveals the thought that services can be the integral components of a manufacturing activity, and these two activities can therefore work to complement or support the other. Based on the cited information above, Saccani et al. would want to imply that in order to obtain profitability in the manufacturing industry, the need to consider after-sales services is a must. This is of great consideration, because establishing high-value for customers must

The Presence of Horror and Fear in ‘the Monkey’s Paw’ Story Essay Example for Free

The Presence of Horror and Fear in ‘the Monkey’s Paw’ Story Essay This essay is an analysis of ‘The Monkey’s Paw’, a horror short story by William Wymark Jacobs. This story is about a talisman that shapes like monkey’s paw which has magical powers. It grants three wishes to its owner. It’s given to one family, husband, wife, and their son. They wish for some money, and that wish also become true, they get the money, the exact amount they wished for. But actually that money was the compensation for the death of their son that caused by the accident. Torturing by the sadness of the dead of her only son, the wife wishes for her son back to life again. When knocking is heard at the door, the husband feels scared about what will happened. And before the wife can opened the door, the husband used the last wish. The knocking stop and when the wife opened the door, no one is there. The essay will be focused on how the speaker brings the horror and fear in this story. There are many ways how the horror and fear is delivered in this story, but this essay will only take and explain three of them. The first thing that brings horror and fear is the background of the Sergeant-Major Morris as the previous owner of the talisman, how he could get that talisman. The reader can feels that the talisman has a mysterious background from how the Sergeant-Major feels uncomfortable when telling about the talisman. â€Å"The soldier regarded him the way that middle age is wont to regard presumptious youth. †I have,† he said quietly, and his blotchy face whitened. † It can be seen that the Major seems too quiet and too afraid for the man that wants to tell the story about the talisman that can granted wishes. Second, the horror and fear come up to the climax through the action or response the husband and wife after the death of their son. The fight between the husband and the wife about the wish to revive their only son also bring the reader feels the horror and fear. â€Å"The old man turned and regarded her, and his voice shook. â€Å"He has been dead ten days, and besides he – I would not tell you else, but – I could only recognize him by his clothing. If he was terrible for you to see then, how now? †Ã¢â‚¬  it brings the readers get the imagination how scary in looks if the son come back to life. The last thing that is, how the narration also supports to create a horror and fear atmosphere in the story. The best example can be seen from the last event. But her husband was on his hand s and knees groping wildly on the floor in search of the paw. If only he could find it before the thing outside got in. A perfect fusillade of knocks reverberated through the house, and he heard the scraping of a chair as his wife put it down in the passage against the door. He heard the creaking of the bolt as it came slowly back, and at the same moment he found the monkey’s paw, and frantically breathed his third and last wish. † The narrations which explain about the setting, the situation and condition also take an important role to raise the tension of fear in this short story. In sum, there are many ways of how the speaker is delivered the horror and fear of this short story. Three of them are: The background of the Sergeant-Major Morris as the previous owner of the talisman, The action or response from the husband and wife about the wish to revive their son, How the narration explain the setting, situation, and condition in this story with a ‘spooky’ ways. There are still many others ways how the speaker brings the horror and fear in this story that make this story become a good horror story.

Advantages And Disadvantages Of Networked Medium Information Technology Essay

Advantages And Disadvantages Of Networked Medium Information Technology Essay Bus networks use a common backbone to connect all devices. A single cable, the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. A device wanting to communicate with another device on the network sends a broadcast message onto the wire that all other devices see, but only the intended recipient actually accepts and processes the message. Ring topology: In a ring network, every device has exactly two neighbors for communication purposes. All messages travel through a ring in the same direction. A failure in any cable or device breaks the loop and can take down the entire network. Star topology: Many home networks use the star topology. A star network features a central connection point called a hub that may be a  hub,  switch  or router. Devices typically connect to the hub with Unshielded Twisted Pair (UTP) Ethernet. Compared to the bus topology, a star network generally requires more cable, but a failure in any star network cable will only take down one computers network access and not the entire LAN. b) Advantages and disadvantages of each medium. Network medium is the physical channel that used for transmission in the network. The types of the medium are: Wire Fiber air Wire: UTP cable is a medium that is composed of pairs of wires.  UTP cable is used in a variety of networks. Each of the eight individual copper wires in UTP cable is covered by an insulating material. In addition, the wires in each pair are twisted around each other. Fiber: Long distance signal transmission. Large Bandwidth, Light Weight, and Small Diameter Long Lengths Easy Installation and Upgrades Non-Conductivity Security Designed for Future Applications Needs Air: Mobility. Elimination of unsightly cables. c) Recommendation for topology and medium to use: Topology: Figure 1.1 : Star topology We select the star topology for this in-house network. Because the star topology is most popular topology for in-house network (LAN). Also we can be benefit by using the star topology in a LAN. Benefits: Information can be easily shared allowing for quick and informed decisions to be made, saving time and money. A more productive and competitive environment is achieved through greater teamwork within the organization. Network-based communication such as email is considerably cheaper than using the phone or fax and sharing resources such as printers gives more efficient use of equipment at lower costs. Standard versions of procedures and directories can be made accessible to everyone. IT administration can be centralised. Data can be backed-up from a single point on a scheduled basis ensuring consistency. Medium: Figure1.2: WI-FI network We select the WI-FI for this in-house network. Because Mobility. Elimination of unsightly cables. Problem Identification: Task 2 10 Marks Investigate the Internet connection requirements for the Fire Department. a) Describe the Internet services that may be required. b) Explain the connection speeds that are suitable for these requirements. c) Find examples of Internet Service Providers (ISPs) that can meet these requirements in your country. d) Make a recommendation to use one ISP based upon the services offered and price charged. Solution of Task 2 a) Hardware and Software Requirements: Computer with either: Windows 95, Windows 98, Windows ME, Windows XP Professional, Windows NT 4.0, Windows 2000, or Windows Server 2003 installed. A CD-ROM drive for the installation compact disc. Adequate disk space for the database, business objects, and Web pages 10 MB free space minimum. Transmission Control Protocol/Internet Protocol installed. A network adapter card and local area network connection. An Internet connection and Internet Protocol address from your Internet Service Provider. Network Adapter board. Figure 2.1: Intranet network system b) Connection speeds requirements: 512 for upload is standard connection for sound only, the much required is 138 kbps, means that 512 138 = 374 kbps free for chat or image. Usually, download > upload is possible for internet provider to have busy server and in this situation you will be connected from phone standard line, with smaller speed. So in this system it demands 512 kbps connection speed. c) Examples of Internet Service Providers in our country: Brack net. Zip. Qubee. Grameen phone Internet. Bangla lion. Recommendation to use the ISP : In this system we select Qubee as out ISP because, Qubee has the solution which is fast and reliable. Very much cost effective. More then it is driven by WI-MAX technology.   And obviously it is portable.

As a minimum include the following information: a) How each method works (frequencies, full/half duplex, etc). b) Details of the legal requirements for operating the system in your country. c) Costs of setting up and operating the system, including licensing costs, equipment costs, etc. d) Limitations of each method. Provide a recommendation for how voice communications should be set up and run including reasons for this recommendation. Solution of Task 3 Method of full/half duplex system: Half-Duplex: A  half-duplex  system provides for communication in both directions, but only one direction at a time. Typically, once a party begins receiving a signal, it must wait for the transmitter to stop transmitting, before replying. An example of a half-duplex system is a two-party system such as a walkie-talkie style two-way radio, wherein one must use Over or another previously designated command to indicate the end of transmission, and ensure that only one party transmits at a time, because both parties transmit on the same frequency. A good analogy for a half-duplex system would be a one lane road with traffic controllers at each end. Traffic can flow in both directions, but only one direction at a time with this being regulated by the traffic controllers. Full-Duplex: A  full-duplex  system allows communication in both directions, and unlike half-duplex, allows this to happen simultaneously. Land-line telephone networks are full-duplex since they allow both callers to speak and be heard at the same time. A good analogy for a  full-duplex  system would be a two-lane road with one lane for each direction. Examples:  Telephone,  Mobile Phone, etc. Two way radios can be, for instance, designed as full-duplex systems, which transmit on one frequency and receive on a different frequency. This is also called frequency-division duplex. Frequency-division-duplex systems can be extended to farther distances using pairs of simple repeater stations, owing to the fact that the communications transmitted on any one frequency always travel in the same direction. Full-duplex Ethernet connections work by making simultaneous use of all four physical pairs of twisted cable, where two pairs are used for receiving packets and two pairs are used for sending packets, to a directly connected device. This effectively makes the cable itself a collision-free environment and theoretically doubles the maximum bandwidth that can be supported by the connection. There are several benefits to using full duplex over half duplex. First, time is not wasted since no frames need to be retransmitted as there are no collisions. Secondly, full bandwidth is available in both directions because send and receive functions are separated. Third, stations/node do not have to wait until other operations complete their transmission as there is only one transmitter for each twisted pair. Legal requirements for operating the system in our country: 1.1 As per the national frequency allocation plan 2005 (nfap 2005), spectrum from the ism band in 2.4000-2.4835 ghz and 5.725-5.875 ghz is allocated for wi-fi use. 1.2.  Ã‚  Ã‚   Access to the spectrum will be on shared basis. There will be no exclusive assignment to any individual or organizations, whether for private, public or commercial use. 1.3.  Ã‚  Ã‚   Any government or private organization/educational institution/corporate body can establish and use wi-fi network on non commercial/non-profit basis. 1.4.  Ã‚  Ã‚   Household/private users are not required to take any permission from the commission or pay any levy/charge for using wi-fi in the given ism band. 1.5.  Ã‚  Ã‚   Both indoor and outdoor wi-fi is permitted in the given spectrum of ism band. However, the maximum power output for the wi-fi equipment is limited to 1 watt. 1.6.  Ã‚  Ã‚   All commercial wi-fi hotspot operators/service providers shall possess an isp or equivalent license (e.g., bwa license). Existing operators having such license from the commission will be eligible to establish wi-fi network for providing last mile solution. 1.7.  Ã‚  Ã‚   Operators/service providers will submit a detailed list of wi-fi outdoor hotspots to the commission. There will be levy/charges applicable annually for all hotspots. the levy/charge shall be charged as per the rate list published by the commission. 1.8.  Ã‚  Ã‚   All service providers will obtain permission in the form of no objection certificate (noc) from the commission for importation, deployment, use and providing any service with wi-fi equipment. Guideline for application and application form is available at http://www.btrc.gov.bd. Existing ism band operators who wish to adapt their present wi-fi equipment for the same purpose may also be provided permission from the commission on case by case basis. 1.9.  Ã‚  Ã‚   All vendors in possession of dealer possession and radio communication equipment vendor license issued by the commission are eligible to apply for noc for importation and marketing of wi-fi equipment in Bangladesh. 1.10. The commission reserves the right to cancel the permission if any complication arises anytime. c) Costs of setting up and operating the system, including licensing costs, equipment costs: The cost of operating the system: The cost of operating the system Purpose Cost 01. 1pr cross connect wire wh/red red/white 1m feet 3000/= 02.

Total 10,1,000/= Table-3.2 The cost of equipments Limitations of each method: During the time when one wave passes through another we say that the waves  interfere. It is really not correct to say that the waves collide or hit, although this is often how such an interaction is termed. When the  crest  of one wave passes through, or is  super positioned  upon, the  crest  of another wave, we say that the waves  constructively interfere. Constructive interference also occurs when the  trough  of one wave is super positioned upon the  trough  of another wave. During any wave interference the shape of the medium is determined by the sum of the separate amplitudes of each wave. We often say that when waves interfere, amplitudes add. Using the arrow buttons step through the above animation to see how the amplitudes add during constructive interference. Notice that in this animation the crest of the red wave constructively interferes with the crest of the blue wave. Recommendation for voice communications set up: Wireless Fidelity, better known as Wi-Fi, is a term used to describe the underlying technology of wireless local area networks based on the Institute of Electrical and Electronics Engineers 802.11 standards. Initially intended to connect mobile computing devices in local area networks, Wi-Fi applications have grown to include various data, voice, and video services such as Internet access and Voice over Internet Protocol. Wi-Fi technology platform is based on single-carrier direct-sequence spread spectrum and multi-carrier Orthogonal Frequency Division Multiplexing radio technologies to transmit and receive signals. Wi-Fi is more commonly used in point-to-multipoint environments to allow extended network connectivity of multiple portable devices such as laptops, telephones, or PDAs. Wi-Fi also allows connectivity in point-to-point mode, which enables devices to directly connect and communicate to each other. A region covered by one or more APs is considered a hotspot. Home networks commonly deploy one AP that is typically connected directly to an Internet service provider , whereas larger networks may require at least several APs positioned in strategic locations to provide flexibility of service to a large number of users. Because of range constraints, Wi-Fi networks are used in localized regions. Figure 3.1: Common Wi-Fi Network Wi-Fi can be used in conjunction with other emerging wireless technologies, such as Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Mesh Networking, to extend the coverage area of terrestrial networks and to provide high-speed mobile data and telecommunications services. For example, WiMAX can be used as a backhaul technology to connect multiple Wi-Fi hotspots with each other and to other parts of the Internet. WiMAX describes the technology behind wireless networks based on the IEEE 802.16 standards. Wi-Fi technology has been highly utilized for many applications such as voice communications, video communications, and various data services. This section describes how Wi-Fi technology supports these applications. The expansion of telecommunications has spawned great need for new technologies to provide sought-after voice communication services. Internet telephony, better known as VoIP, is a technology that allows for transport of voice traffic using an Internet Protocol (IP) network infrastructure. VoIP and Internet telephony have come a long way since their inception, and with the impressive development of Wi-Fi technologies, the popularity of voice communications over wireless will continue to increase. Common VoIP networks consist of the hardware and software enabling the end users to leverage the Internet as the transmission medium for telephone calls. IEEE 802.11 Voice over Wi-Fi is the wireless version of this technology that is designed to work with wireless devices. VoWi-Fi solutions provide mobile users during critical missions with the ability to roam wirelessly. Typically, a VoWi-Fi user device will connect to an AP to authenticate to a designated VoIP network. Once associated to an AP and authenticated to the appropriate network, a user will have the capability of mobile voice communications across enterprise networks, residential broadband networks, or even public/private hotspots. VoWi-Fi products are becoming more advanced and readily available to support various challenging short- and long-term voice service needs, such as in commercial, healthcare, private, and incident site environments. Given the steadily increasing demand for voice services and mobility, wired and wireless VoIP deployments continue to grow and eventually will become more prevalent than traditional circuit switching voice systems. One advantage VoWi-Fi provides over traditional circuit-based voice communications is an ability to easily accommodate user growth in many different operating environments, through software configuration. Typically, physical attributes of circuit-switched voice systems can limit the flexibility of real-time configuration. Deploying a wireless VoIP system can provide significant savings in cost and deployment time when compared with other wireless voice communication solutions.

Entropy, Pollution and Global Warming Essay -- Greenhouse Gases Climat

Entropy, Pollution and Global Warming The substances that we as human beings classify as 'pollutants' have always been present on the planet, because the earth is a closed system. The reason that these materials cause a negative impact on the environment, therefore, is not that they exist, but that they have been dispersed throughout the world's ecosystems in a very disordered fashion. To illustrate this, two pollutants of major concern will be considered, carbon dioxide (CO2) and sulphur dioxide (SO2). CO2 and SO2 are both given off when coal is burned to provide heat or to generate electricity. CO2 is the most important greenhouse gas contributing to global warming, and SO2 is the main cause of acid rain. Carbon and sulphur have no impact on the environment when they are locked up in ...

Whole Language versus Phonics Essay -- Education Language Communicatio

Whole Language versus Phonics Whole Language versus Phonics has been a question among many top educational groups for years. Which is the best way to teach kindergarten children the proper way to speak and learn the English Language? There are many valid reasons why experts argue for both phonics and/or whole language. Both seem to be exceptional ways to master the English Language. The purpose of this research paper is to compare phonics versus whole language and to determine how technology can support each approach. The history of the use of phonics dates back to the 1700’s. Backs then, children were taught to read through their memorization of the twenty-six-letter alphabet. Since many books hadn’t been written, their primary textbook was the Bible. Although there is no accounts for when whole language originated some believe that it was around the same time as phonics. The whole language reading method was widespread for thirty years, from around 1940 to 1970. From around 1970 to 1990, phonics was popular. Whole Language gained the most recent foothold around 1990. (Stahl 1996) Several times they have gone back and forth. The debate over whole language and phonics has gone on for years. Which way is best in teaching children how to read? The education world has been debating this issue for years and there still are no exact answers. In more recent year’s instruction specialist have argued that some sort of middle ground should be reached because it would give children the benefits of both. (Cromwell 1997) Some form of middle ground needs to be obtained if children’s needs are going to be met. What is whole language? It is the process of learning a language through whole word teaching.

Nummi

As we compare to Japanese and American culture we can more or less comment on why GM was having difficulties while learning from the ANNUM experience. The GM plant in Fremont, California was opened in 1963 and closed down in 1982 due to bottom ranked in productivity among GM plants and the reputation of the worst quality cars in the entire GM system. The major problem was heavily relying on mistrust and fairness between management and union.Whereas Toyota at Annum showed the importance of using all means available to establish a climate of fairness such as flat organization, fewer levels of management, no exclusive bonuses and no distinctions between managers and team members such as using the same cafeteria for lunch or no dress differences. The core values were customer satisfaction by means of high quality and low cost, dignity, trust, teamwork, consistency, continual improvement. This sort of approaches was quite different from happily American manufacturing culture as well as it s culture itself.Japanese already discovered that in order to maintain waste free and high quality production they have to work well with people work on the line and provide them to the same privilege as white collar employees. Employees In most Japanese companies stay In the companies from low position to higher position and they generally work In the companies for their whole career. In the U. S. Companies often go through massive reorganization, therefore employees will be promoted or laid off.

Moral matters Essay

PRAYER is the center for Jesus. Religion has two aspects: On the one hand it maintains certain standards of conduct, on the other it affirms certain beliefs about the ultimate nature of the universe. It is prayer which connects the two. Without it the one of these would be ethics, and the other would be theology. Prayer makes them elements in religion. In prayer the individual brings together God, life’s ideal values, and himself. It is evident from the gospels that Jesus believed in prayer, told men to pray, and prayed himself. Mark narrates how early in the morning before others are about he withdraws to the desert to pray (Mark 1:35). Late in the evening after teaching the multitudes all day he goes into a mountain to pray (Mark 6:46). The hours before the arrest are spent in prayer. Luke is particularly interested in the prayers of Jesus, and adds to Mark’s account various other references. At the time of the baptism, when the heavens opened and he saw the vision, he was praying (Mark 14:32). When the multitudes crowded upon him after the healing of the leper, â€Å"he withdrew into the deserts and prayed (Luke 3:21). † Before choosing the Twelve, and before he asked the disciples what they thought of himself, he was in prayer (Luke 5:16). The Transfiguration occurred when he was at prayer (Luke 6:12, 9:18). The request of the disciples, â€Å"Lord, teach us to pray,† was made at the close of one of his periods of prayer (Luke 9:28). Some of these may be editorial additions in order to provide settings for sayings or incidents where the actual occasion had been forgotten, but there can be no doubt that they represent an authentic record of the practice of Jesus. One notices immediately several facts about these acts of prayer. In the first place, a considerable number of them occur at times of decision and crisis. Important junctures and turning points in Jesus’ career were approached after long periods of silent meditation and prayer. In the second place, one notes that prayer was for Jesus a refreshing and invigorating experience. From the turmoil, confusion, and fatigue of dealing with the multitudes he sought refuge in withdrawals for quiet prayer. His words to his disciples show what these retreats meant to himself. â€Å"Come ye yourselves apart into a desert place and rest awhile,† he said when they returned telling of their strenuous campaign through the cities and villages of Galilee (Guignebert 67). Such experiences of rest, reflection, and prayer Jesus himself had found necessary in order to carry on the spiritually and emotionally exhausting undertaking in which he was engaged. Such a practice of prayer throws valuable light on Jesus’ own religion. In spite of his clarity of mind and intuitive understanding of religious and moral matters, in spite too of his independence and the authority with which he taught, it is evident that Jesus had no sense of religious self-sufficiency and personal adequacy. His intuitive moral judgments and his consciousness of authority to proclaim God’s will were rather the results of these hours in which he sought to ascertain the purposes of God and to be led by him. If one should ask what Jesus taught about prayer, it must be answered that he gave very little definite teaching. There were certain things he said about it, but he gave no set rules or systematic directions for prayer. To him it was an intensely personal thing, and never to be reduced to form or ritual. Professor Bundy, speaking of Jesus’ retreats for the purpose of prayer, remarks that there was no regularity about these retreats. â€Å"They were in no sense a part of a prayer system. For Jesus prayer was not a traditional religious exercise to be engaged in and observed at certain set hours, but the spontaneous impromptu practice of an intense personal piety. † Indeed one learns more about prayer as Jesus practiced it from his own prayers recorded in the gospels than from any instructions he gave about praying. By putting together precept and practice one can learn something of his conception of prayer and the objects for which he thought men should pray (Taylor 145-50). First and foremost should be placed the fact that Jesus repeatedly and in the strongest possible language urged his hearers to pray. â€Å"Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: for every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened. Or what man is there of you, who, if his son ask for a loaf, will he give him a stone; or if he ask for a fish, will he give him a serpent? If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father who is in heaven give good things to them that ask him? † (Matt. 7: 11) On other occasions he was even more emphatic. â€Å"If ye have faith as a grain of mustard seed,† he said in extreme illustration, â€Å"ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you. † By such words he tried to impress upon his hearers that God gives heed to prayer. For he knew that the reason men do not pray is that they do not believe that anything will be accomplished by it. God does hear and answer the prayer of faith. To Jesus prayer was not a process of autosuggestion or a devotional ritual with subjective values, but an actual source of power for accomplishment (Pannenberg 267)
