Internet Small Computer System Interface Essay Example for Free

Web Small Computer System Interface Essay A heterogeneous system of both IP-based SAN’s and FCP-based SAN’s ought to be arrangement dependent on a standard naming show so as to encourage correspondence between the customer applications and the SAN which stores data. The system engineering ought to in a perfect world be arrangement utilizing a naming show which is basic and exact, while encouraging correspondence between the entirety of the system assets. This strategy depends on having a show which interfaces an assortment of advancements together just as different assets seen on a system. A heterogeneous system comprises of different system hubs with different conventions and working frameworks in activity together. On account of a Storage Area Network (SAN), the different working frameworks being used on the system should have the option to consider the to be capacity volumes as though they are privately connected, consequently speed is basic to the effective working of a SAN. The utilization of an illustrative naming show is likewise significant as it implies issue ID can be made simpler and assists with limiting administrator mistakes on the system. There are various conventions in procedure on each system, and the requirement for an effective convention for SAN use is fundamental. The present alternatives for running a SAN are to utilize standard TCP/IP conventions in particular the Internet Small Computer System Interface (iSCSI) convention, or to utilize a particular convention called FCP which ordinarily works over bespoke fiber framework. These conventions are distinctive in the manner they work, anyway can in reality be utilized together to improve the presentation of a SAN. A naming show appropriate for a TCP/IP based system is altogether different to a naming show for a FCP based system. TCP/IP is a system convention which is utilized for correspondence between assets on a standard LAN, anyway FCP is a convention which sends SCSI orders by means of a fiber optic link to remote stockpiling gadgets. The iSCSI convention permits different system stockpiling assets to be recognized and utilized over standard system conventions, which requires consistence with the standard system naming strategy, yet which empowers the particular idea of their activity to be distinguished. Naming shows for the LAN and SCSI stockpiling gadgets ought to agree to standard system naming shows. The servers and iSCSI gadgets which work on a system ought to be been named in consistence with a standard strategy and ought to be one of a kind on the switch texture of the system. Standard SAN naming shows ought to be made in view of a couple of elements, every segment ought to be named dependent on its physical area, what it interfaces with, which database it is utilized by, and another extraordinary field of ID. Naming shows are significant in light of the fact that they can spare chairmen time and exertion, and must be made while thinking about numerous variables. At first there must be a framework whereby arrange names are made midway and remarkably with the goal that copy records are not made. This naming methodology must be reliable all through the system, and it must be applied over the whole association paying little heed to area or activity. This component of the naming show assists with forestalling the trickery or disarray of system names and is required to empower an elite system to work. This issue isn't so significant when managing a FCP-based SAN, on the grounds that the gadgets are associated by a different system of fiber which can't as a rule be gotten to by assets on the standard system which don't utilize explicit applications or databases. Taking everything into account the activity of a capacity region arrange depends on speed and a proficient and viable naming framework which can be overseen, analyzed and fixed where vital in the least complex and most financially savvy way that could be available. This must be done reliably when utilizing the standard TCP/IP convention, anyway explicit FCP SAN convention takes into account an a lot less difficult show.

Saint Clare Essay Example for Free

Holy person Clare Essay St. Clare was conceived on July 16, 1194 and passed on August 11, 1253. She was the girl of a tally and lady. She heard St. Francis lecture in the boulevards of Assisi and let him know of her craving to offer herself to God. They developed to be dear companions. On Palm Sunday in the year 1212 the priest of Assisi introduced a palm to this respectable house keeper of eighteen who was delightfully garbed. That equivalent night she left her mansion with one associate and went to the congregation of Our Lady of the Angels, where she met Francis and his Brothers. At the raised area of Our Lady, Francis remove her hair and Clare gave her life to Christ. In an old house outside Assisi she started her Order of the Poor Clares. Afterward, her sister and mom and other honorable women joined her. They carried on with an existence of supplication, quietness and fasting. At some point, adversaries of the Church were going to assault the cloister. The holy person had the Blessed Sacrament set in a monstrance over the entryway of the community and, bowing before it, she appealed to God for help. Unexpectedly the foe fled. During her sickness of 28 years the Holy Eucharist was her quality. She passed on in 1253. She is the patroness of, eye infection, goldsmiths, clothing, embroiderers, gilders, great climate, needle laborers, Santa Clara Pueblo, phones, broadcasts, and TV. Pope Pius XII chose her as the benefactor holy person of TV in 1958, on the premise that when she was too sick to ever be available at Mass, she had purportedly had the option to see and hear it on the mass of her room. Her remaining parts were buried at the house of prayer of San Giorgio while a congregation to hold her remaining parts was being manufactured. On August 15, 1255, Pope Alexander IV consecrated Clare as Saint Clare of Assisi. Development of the Basilica of Saint Clare was finished in 1260, and on October 3 of that year Clares remains were moved to the as of late finished basilica where they were covered under the high special raised area. In further affirmation of the holy person, Pope Urban IV formally modified the name of the Order of Poor Ladies to the Order of Saint Clare in 1263. Around 600 years after the fact in 1872, Saint Clares remains were moved to a recently built commemoration in the grave of the Basilica of Saint Clare where they can in any case be seen now.

Reading Pathway C.S. LEWIS

Reading Pathway C.S. LEWIS C.S. Lewis (1898-1963) was one of the greatest authors and apologists of the twentieth century. He was a paradoxical manâ€"intensely private and world famous, a family man and confirmed bachelor until later in life, and a staunch atheist who became a reluctant evangelist. He is the chosen literary icon of modern American Evangelicals, but despite the fact that most of his writing heavily reflects his Christian faith, his appeal extends far beyond a single denomination or religion. Lewis’s work is remarkable not only for its clarity and insight into the human condition, but its breadth. During his sixty-four years Lewis wrote poetry, fantasy and science fiction, academic and popular nonfiction, essays, and more, so it’s difficult to choose just three books to start with. My reason for picking these particular books is because each one reflects a key period of Lewis’s lifeâ€"his literary childhood, his conversion to Christianity and subsequent rise to fame, and the years leading up to his death. I. The Lion, the Witch and the Wardrobe The first book in the Narnia series (or the second, if you read in chronological order1) was published in 1950. In addition to being one of most popular children’s books of all time, it provides insight into Lewis’s literary and creative interests as a child. Little Lea, Lewis’s childhood home, was well stocked with books, and he spent many rainy days reading and writing about imaginary worlds with his brother, Warnie. The children’s author Edith Nesbit left a particular imprint on Lewis’s young mind. Certain plot lines in her book, The Magic World (1912), are quite similar to those in The Lion, the Witch, and the Wardrobe. In fact, both books feature wardrobes that double as thresholds to magical worlds. Lewis’s friend and colleague J.R.R. Tolkien thought the Narnia series lacked depth. Though the series heavily reflected his childhood flights of imagination, it is highly probable that Lewis imbued  what could have been a simple children’s fantasy with a symbolism that Tolkien missed. Scholar Michael Ward posited in 2008 that each Narnia novel corresponds to one of the seven planets in the medieval understanding of the universe. 2 Lewis’s longstanding fascination with medieval symbolism and mythology supports this theory. II. Mere Christianity World War II brought with it a renewed interest in religious matters in Great Britain. As a result, the BBC hired Lewis to give a series of broadcast talks to address the spiritual concerns of the British people. These broadcast talks were later published in three volumesâ€"Broadcast Talks (1942), Christian Behaviour (1943), and Beyond Personality (1944). Though interconnected, they were viewed by the general public as separate works, so Lewis combined and amplified them to create Mere Christianity, published in 1952. Mere Christianity is Lewis’s seminal evangelical workâ€"a logical argument for the Christian faith and a call for peace and cooperation between the various denominations therein. Many apologetic works have been based on it, and it’s probably Lewis’s best-known work after The Chronicles of Narnia. The broadcast talks were what catapulted Lewis to fame in England, and the publication of Mere Christianity spread his fame to America.   III. A Grief Observed Before  1961, Lewis’s nonfiction was primarily intellectual in nature. Then, his wife of four years, Joy Davidman, died of cancer, leaving him devastated. He took to the page in his grief, writing a highly emotional account of the spiritual questions and doubts that her passing raised for him. It’s a raw and unabashedly honest book that challenges the soundness of Lewis’s earlier arguments about pain and its place in the life of faith (outlined in The Problem of Painâ€"a good book to read in conjunction with  this one, but certainly not necessary) when faced with the actual experience of suffering. Lewis was notoriously uncomfortable with expressing sentimentality in his writing and took great pains to disguise his authorship of A Grief Observed when it was published. He used a pseudonym and altered his usual writing style to avoid detection. Even so, T.S. Eliot, then a director at the publisher Faber and Faber, recognized the manuscript’s author immediately. Once you’ve finished these three books, you’ll have a basic idea of who Lewis was as a writer. Obviously you should read everything he’s ever written, but a couple of good follow-up books to start with are The Screwtape Letters, a novel written as a series of letters between a demon and his protégé, and C.S. LewisA Life by Alister McGrath. The latter is an excellent biography that gives a wonderful overview of his life and insight into his works. _________________________ 1I personally recommend reading the books in the order they were written or published. As Alister McGrath points out in C.S. Lewis: A Life, “The chronological approach raises considerable difficulties for readers. For example, the events of The Horse and His Boy actually occur during, not after, those of The Lion, the Witch, and the Wardrobe.” 2For a layman’s overview of this theory, read The Narnia Code: C.S. Lewis and the Secret of the Seven Heavens. For an in-depth scholarly analysis read Planet Narnia: The Seven Heavens in the Imagination of C.S. Lewis, both by Michael Ward.

The Military Decision Making Process Essay - 1406 Words

The Military Decision Making Process (MDMP) is an analytical and deliberate process that commanders follow using seven steps that includes the receipt of the mission, mission analysis, course of action development, course of action analysis, course of action comparison, course of action approval and orders production. The MDMP gives leaders a thorough process to follow that provides clarity and synchronization for operations even under time-constrained environments. We need an Army that is trained on making decisions, able to anticipate needs and able to be proactive in accomplishing tasks even when unexpected duties arise. The MDMP sets the Army up for success in getting to this point. Without the MDMP, leaders will struggle to make crucial decisions and they will certainly struggle to make them under pressure during time sensitive missions. Not just our own history but the history of other countries has shown that running military operations without planning properly can result in inconceivable losses. At the National Defense Executive Reserve Conference on November 14, 1957, Dwight D. Eisenhower was quoted as stating: â€Å"I heard long ago in the Army: plans are worthless, but planning is everything.† The MDMP is a single, established, and proven analytical process (US Department of the Army, 1997).

Arthur Kornberg A Nobel Laureate Free Essays

Arthur Kornberg was born on March 3, 1918 in Brooklyn, New York. He was educated in Abraham Lincoln High School and continued his education at the City College of New York. This was where he first received his scientific training as he graduated with a degree in science in 1937. We will write a custom essay sample on Arthur Kornberg: A Nobel Laureate or any similar topic only for you Order Now He received his medical degree in 1941 from the University of Rochester and proceeded with his internship in internal medicine. He then served in the U.S. Public Health Service as a commissioned officer where his first assignment was to be doctor in the Navy, serving as a ship’s doctor. Fortunately, he was given the opportunity to continue his research work as a scientist at the National Institute of Health in Bethesda, Maryland. He served at the NIH from 1942 to 1953. This is where he decided to direct his research to mainly concentrate with enzymes. Dr. Kornberg received further studies and training in enzymology. In New York University School of Medicine, he trained with Professor Severo Ochoa in 1946. A year later, he pursued enzymology with Professor Carl Cori at the Washington University School of Medicine. He later returned to service at the NIH and became the organizer and director of the Institute’s Enzyme Section. He later received an offer as the chairman of the Department of Microbiology of Washington University School of Medicine in St. Louis, Missouri prompting him to resign his position of Medical Director in Bethesda. He later transferred to Standford University School of Medicine in 1959. This is where he organized a Department of Biochemistry and served as the chairman until 1969. After his term, he served as a professor and in 1988 he accepted the title Professor Emeritus (Kornberg 2005, Kumin 2005). Dr. Kornberg devoted most of his studies isolating and purifying enzymes significant in cellular machinery. Until the first half of the 20th century, questions on enzymatic function and their cellular specificity were left unanswered. This became Dr. Kornberg’s primary area  of interest. In 1941, Beadle and Tatum from Standford demonstrated that through chemical functions, genes control life processes. Immediately after this discovery, Oswald Avery and his team from the Rockefellar Institute asserted that DNA drives this process instead of proteins, which was the primary assumption of the scientific community. Later, the famous James Watson and Francis Crick discovered the first detailed model of the DNA, demonstrating its structure as the well-known double helix (McCook 2007 and Telegraph.co.uk 2007). The primary subject of Kornberg’s research was due to his interest in discovery enzymatic mechanisms and functions. Together with Dr. Severo Ochoa, he discovered the ezyme Polymerase I which is the primary catalyst of DNA synthesis. They were awarded the Nobel Prize in 1959 for their elucidation of the basic DNA replication mechanisms (Kumin 2007 and McCook 2007). This success of Kornberg in producing a chemically exact and inert genetic material called the DNA is a milestone in the field of biochemistry. It is an important leap towards the understanding of the material that compose the genes. This is important in the issues and questions on inheritance and transmission of traits (Telegraph.co.uk 2007). Kornberg and Ochoa both specialized on the field of protein biochemistry. But this breakthrough discovery was actually concerned mainly on the field of molecular genetics. His primary technique was to isolate enzymes in a chemist’s lab and comprehending them biologically. This is a very significant approach in understanding of cellular molecular biology. In 1967, Kornberg successfully synthesized the first active virus within a lab. It was identified as PhiX174, a biologically active virus synthesized by a biochemist (Kumin 2007 and Altman 2007). After his extensive research on enzymatic synthesis of coenzymes and inorganic pyrophosphate, his interest led him to the study of the biosynthesis of nucleic acids,  particularly DNA. He demonstrated the pathways of pyrimidine and purine nucleotide synthesis, elaborating with the mechanisms and detailed steps on the process. Here, he found that there is an intermediate PRPP to the enzyme concerned in the assemblage of building blocks into DNA.   It was named as DNA polymerase. This particular enzyme is found in almost all cellular systems that synthesize genetically precise DNA. This is very important in the processes of replication, repair and rearrangements of DNA. Further research identified enzymes responsible for DNA metabolism, allowing the initiation and elongation of DNA chains and chromosomes. This paved the way for the discovery of recombinant DNA, a breakthrough technology that ignited the biotechnological revolution (Kornberg, 2005). After decades in the research on DNA replication, he diverted his concentration to studies in inorganic polyphosphate (poly P) in 1991. Poly P is a phosphate polymer that was hypothesized to have participated in prebiotic evolution. This polymer is basically found in every bacterial, plant, and animal cells. It has been dismissed as simply a molecular fossil, Kornberg found that there are different functions for poly P including stress responses, motility, and virulence in some pathogens (Kornberg, 2005). Besides conducting research studies, he has other pursuits such as educating graduate, medical and postdoctoral students. He also authored several monographs such as â€Å"DNA Synthesis† in 1974, â€Å"DNA Replication† in 1980, â€Å"Supplement to DNA Replication† in 1982, and Second Edition of â€Å"DNA Replication† in 1992. He also published a scientific autobiography entitled â€Å"For the Love of Enzymes: The Odyssey of a Biochemist† in 1989. Published by Univesity Science Books in July 1995, he released his book entitled â€Å"The Golden Helix: Inside Biotech Venutre† which provided insights on the biotechnology from an expert (Kornberg, 2005). His academic career included his presidency of the American Society of Biological Chemistry in 1965. He also served as a president on advisory boards and councils of numerous universities, governmental, and industrial research facilities. He founded the  DNAX Research Institute of Molecular and Cellular Biology that is a division of Schering-Plough, Inc. He also served as a member of its Policy and Scientific Advisory Boards. Futhermore, he served on the Scientific Advisory Boards of Regeneron Pharmaceuticals, Inc., Maxygen, and the Xoma Corp., and was also a member of the Board of Directors of XOMA Corporation (Kornberg 2005). Contributing further to his excellent curriculum vitae, he has received honors and gained memberships in the National Academy of Sciences, the Royal Society, American Philosophical Society, and a number of honorary degrees such as the Nobel Prize in Physiology or Medicine in 1959, the National Medal of Science in 1979, the Cosmos Club Award in 1995, and more. Arthur Kornberg died on March 26, 2007 due to respiratory complications (Kornberg, 2005 and Altman 2007). Undoubtedly, Kornberg’s contribution to the biotechnological society is unwavering. His research has paved the way for most of the scientific advances that the world is currently witnessing. His studies have proven indispensable in the understanding of human heredity, cellular mechanisms, and pyrophosphate functions. References Altman, Lawrence K.

It would make it a criminal offense to make available to children anything that is indecent, or to send anything indecent with intent to annoy, abuse, threaten, or harass (Stop the Communications ... n.p.). The goal of this bill is to try to make all public discourse on the Internet suitable for young children. The issue of whether is it necessary to have censorship on the Internet is being argued all over the world. Censorship would damage the atmosphere of the freedom to express ideas on the Internet; therefore, government should not encourage censorship. The Internet was originally a place for people to freely express their ideas worldwide. It is also one of America's most valuable types of technology. Ordinary people use the Net for communication, expressing their opinions, or obtaining up-to-date information from the World Wide Web (WWW). The Internet can be compared to a church. In many ways the Internet is like a church: it has its council of elders, every member has an opinion about how things should work, and they can either take part or not. It's the choice of the user. The Internet has no president, chief operating officer, or Pope. The networks may have presidents and CEO's, but that's a different issue; there is no single authority figure for the Internet as a whole. As stated by Frances Hentoff, the staff writer for The Village Voice and the author of First Freedoms, on an info superhighway driven by individuals, there are no cops preventing users from downloading (Hentoff 1). Internet users can broadcast or express anything they want. The fact that the Net has no single authority figure sets forth a problem about what kind of materials could be available on the Net. The U.S. government is now trying to pass bills to prevent misuse of the Net. The Internet Censorship Bill of 1995 was introduced to the U.S. Congress. Under the Censorship Bill, a person breaks the law if he/she puts a purity test on a web page without making sure children cannot access the page. Also, if a person verbally assaults someone, he/she breaks the law. If a university, where some students may be under 18 years old, carries the alt.sex*. newsgroups, which contains adult material, it breaks the law. According to George Melloan from the Wall Street Journal, a censorship bill was passed by the Senate 84-16 in July, and an anticensorship bill was passed by the House 420-4 in August. There are now four different sets of censorship and anticensorship language in the House and Senate versions of the Telecom m reform bill, which contradict each other and will have to be reconciled (Melloan, n.p.). Another crucial Internet crime is the theft of credit card numbers. Companies do business on the Net, and credit card numbers are stored on their servers; everyone with the necessary computer knowledge could hack in and obtain such databases for illegal purposes. To cite an instance, the most infamous computer terrorist, Kevin Mitnick, waived extradition and is now in jail in California, charged with computer fraud and illegal use of a telephone access device. The list of allegations against him include theft of many files and documents, including twenty-thousand credit card numbers from Netcom On-Line Services, which provides thousands with access to the Internet (Warren 52). Many experts have pointed out that government censorship is not possible. Howard Rheingold, the editor of the Whole World Review, observes that, the 'censor the Net' approach is not just morally misguided. It's becoming technically and politically impossible (Rheingold n.p.). First, it is not fair to exclude the freedom and damage the atmosphere of freely expressing ideas just for the safety of children. Corn-Revere, an expert on Internet censorship at the Howgan & Harson

Create an Internet Shortcut (.URL) File Using Delphi

Create an Internet Shortcut (.URL) File Using Delphi Unlike regular .LNK shortcuts (that point to a document or an application), Internet Shortcuts point to a URL (web document). Heres how to create a .URL file, or  Internet Shortcut, using Delphi. The Internet Shortcut object is used to create shortcuts to Internet sites or web documents. Internet shortcuts are diverse from regular shortcuts (which contain data in a binary file) that point to a document or an application. Such text files with a .URL extension have their content in INI file format. The easiest way to look inside a .URL file is to open it inside Notepad. The content (in its simplest form) of an Internet Shortcut could look like this: [InternetShortcut] URLhttp://delphi.about.com As you can see, .URL files have an INI file format. The URL represents the address location of the page to load. It must specify a fully qualifying URL with the format protocol://server/page.. Simple Delphi Function to Create an .URL File You can easily programmatically create an Internet shortcut if you have the URL of the page to which you want to link. When double-clicked, the default browser is launched and displays the site (or a web document) associated with the shortcut. Heres a simple Delphi function to create a .URL file. The CreateInterentShortcut procedure creates a URL shortcut file with the provided file name (FileName parameter) for the given URL (LocationURL), overwriting any existing Internet Shortcut with the same name. uses IniFiles;...procedure CreateInternetShortcut(const FileName, LocationURL : string) ;begin   Ã‚  with TIniFile.Create(FileName) do   Ã‚  try   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  URL,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  LocationURL) ;   Ã‚  finally   Ã‚  Ã‚  Ã‚  Free;  Ã‚  end;end; (*CreateInterentShortcut*) Heres a sample usage: //create an .URL file named About Delphi Programming //in the root folder of the C drive //let it point to http://delphi.about.com CreateInterentShortcut(c:\About Delphi Programming.URL , http://delphi.about.com ) ; A few notes: You could save a web page as MHT (web archive) and then create a .URL shortcut to be able to access an offline version of a web document.You must provide a full file name, along with the .URL extension, for the FileName parameter.If you already have an Internet Shortcut you are interested in, you can easily extract the URL from an Internet Shortcut (.url) file. Specifying the .URL Icon One of the neater features of the .URL file format is that you can change the shortcuts associated icon. By default the .URL will carry the icon of the default browser. If you want to change the icon, you only have to add two additional fields to the .URL file, as in: [InternetShortcut] URLhttp://delphi.about.com IconIndex0 IconFileC:\MyFolder\MyDelphiProgram.exe The IconIndex and IconFile fields let you specify the icon for the .URL shortcut. The IconFile could point to your applications exe file (IconIndex is the index of the icon as a resource inside the exe). Internet Shortcut to Open a Regular Document or an Application Being called an Internet Shortcut, a .URL file format does not permit you to use it for something else- such as a standard application shortcut. Note that the URL field must be specified in the protocol://server/page format. For example, you could create an Internet Shortcut icon on the Desktop that points to your programs exe file. You only need to specify the file:/// for the protocol. When you double click on such a .URL file, your application will be executed. Heres an example of such an Internet Shortcut: [InternetShortcut] URL file:///c:\MyApps\MySuperDelphiProgram.exe IconIndex 0 IconFile C:\MyFolder\MyDelphiProgram.exe Heres a procedure that places an Internet Shortcut on the Desktop, the shortcut points to the *current* application. You can use this code to create a shortcut to your program: uses IniFiles, ShlObj;...function GetDesktopPath: string;//get the location of the Desktop foldervar   Ã‚  DesktopPidl: PItemIDList;   Ã‚  DesktopPath: array [0..MAX_PATH] of Char;begin   Ã‚  SHGetSpecialFolderLocation(0, CSIDL_DESKTOP, DesktopPidl) ;   Ã‚  SHGetPathFromIDList(DesktopPidl, DesktopPath) ;   Ã‚  Result : IncludeTrailingPathDelimiter(DesktopPath) ; end; (*GetDesktopPath*) procedure CreateSelfShortcut;const   Ã‚  FileProtocol file:///; var   Ã‚  ShortcutTitle : string;begin   Ã‚  ShortcutTitle : Application.Title .URL;   Ã‚  with TIniFile.Create(GetDesktopPath ShortcutTitle) do   Ã‚  try   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  URL,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  FileProtocol Application.ExeName) ;   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  IconIndex,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  0) ;   Ã‚  Ã‚  Ã‚  WriteString(   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  InternetShortcut,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  IconFile,   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Application.ExeName) ;   Ã‚  finally   Ã‚  Ã‚  Ã‚  Free;   Ã‚  end;end; (*CreateSelfShortcut*) Note: simply call CreateSelfShortcut to create a shortcut to your program on the Desktop. When to Use .URL Those handy .URL files will be useful for virtually every project. When you create a setup for your applications, include a .URL shortcut inside the Start menu- let users have the most convenient way to visit your website for updates, examples, or help files.

Basic Video Streaming Problems Essay Example | Topics and Well Written Essays - 500 words

Basic Video Streaming Problems - Essay Example However, there are several drawbacks related to the concept of video streaming. Video streaming has its limitations on the internet because internet does not give any surety of any fixed bandwidth, delay or packet loss. It works on a â€Å"best effort service† (Apostolopoulos et al. 2002). These are considered to be variable factors that change with respect to the quality of internet connection. There have been many researches carried out over the years to induce more reliability and consistency in video streaming. These three issues are discussed in detail: As stated earlier, the bandwidth between two nodes is variable and might not be known. This variability causes problems in the traffic flow from one point to the other (Wu et al. 2001). If the sender sends data at a rate which is faster than the available bandwidth then congestion and low quality streaming is resulted. On the contrary, if the sender sends data at a rate which is slower than the available bandwidth then the receiver decodes a sub-optimal video quality (Apostolopoulos et al. 2002). A strategy to overcome this problem is to ensure a bandwidth that is acceptable to both the nodes; this can be done by estimating the available bandwidth and striking a balance between the estimated bandwidth and video bit rate transferred over the link. The degree of this issue varies from packet to packet. The variation in the delay of every packet depends on its respective queues on different routers. If there exist some variations in the end-to-end delays then it is known as delay jitter (Apostolopoulos et al. 2002). The main reason behind this problem lies in the fact that the receiver is designed to decode and thus display frames at a certain rate. Some frames may arrive at the receiver late due to this delay jitter; this can create a problem at the receiver because he is programmed to decode the frames at a certain rate. These late frames will cause jerks in the display of

Federal Reserve Paper Essay Example | Topics and Well Written Essays - 750 words

Federal Reserve Paper - Essay Example 3. Maintaining the stability of the financial system and containing systemic risk that may arise in financial markets. 4. Providing financial services to depository institutions, the U.S. government, and foreign official institutions, including playing a major role in operating the nation's payments system. Discussion Since the Federal Reserve Act of 1913 the Federal Reserve has been in governance of monetary policy. The policy is controlled by maintaining open market operations, reserve requirements, and discount rates (Monetary Policy, p.1). In section 2A of the Federal Reserve Act the objectives of the monetary policy read â€Å"The Board of Governors of the Federal Reserve System and the Federal Open Market Committee shall maintain long run growth of the monetary and credit aggregates commensurate with the economy's long run potential to increase production, so as to promote effectively the goals of maximum employment, stable prices, and moderate long-term interest rates† (About the Fed, p. 1). In this process the primary function of the central bank is to increase the credit and cash flow. The way this task is completed is by acting as a hub for the Federal Open Market Committee (FOMC). The Federal Reserve Bank relinquishes the funds from depository institutions into public funds. ... 1). Generally in order for the central bank to be successful at this agenda there has to be something of monetary value. The basic function of money is used as a stake horse for the Reserve bank. When the economy is in high demand of currency the Federal Reserve Bank issues it to institutions. When the demand for cash is low the bank will recover money from institutions and allow them to access a credit account (The Structure of the Federal Reserve, p. 1) These involvements along with the influence of the monetary policy will have a visible impact on the economic state. In light of the recent recession there has been some progress made toward fulfilling the monetary policy. The Federal Reserve Chairman, Ben S. Bernanke, made a testimonial over the recent effects of the economic recovery. Based on his report the new monetary policy has not yet had a positive effect. According to the report given by Bernanke the objective for the Federal Reserve to maximize employment and stabilize pri ces is near but offset by an expected decline of employment in 2011. It is expected that with the policy in place the unemployment rate will go down to 8% by 2012. The effects of the currently high unemployment rates force the economy into lower inflation periods. That force places us in range for deflation and is the cause of less production (Bernanke, p. 1). To enforce a consistent upward turn in the objectives of the monetary policy several Acts have been implemented. Of the lot, the Government Performance and Results Act Strategic Planning Document (2008-2011) outlines that the monetary policy goals will be met using the following objectives: 1. Stay abreast of recent developments in and prospects for the U.S. economy and financial markets, and in those abroad, so that monetary

My Antonia Essay: Women on the Frontier -- My Antonia Essays

Women on the Frontier in My Ántonia In 1891, marking the elimination of "free land," the Census Bureau announced that the frontier no longer existed (Takaki, A Different Mirror, 225). The end of the frontier meant the constant impoverishment, instead of the wealth they had dreamed of, for a large number of immigrants from the Old World: they came too late. My Ántonia, however, illuminates another frontier, a frontier within America that most immigrants had to face. It was the frontier between "Americans" and "foreigners." The immigrants were still "foreign" to the "Americans" who came and settled earlier. They had to overcome the language and cultural barrier and struggle against the harsh conditions of life. The novel focuses on the ironic moment that the frontier spirit - a uniquely American one - is realized through "foreigners." Furthermore, it is women, the "hired girls," who are put in the foreground in the novel. What has made America is the foreign within, or rather, the foreign women on the fron tier. The division between the "Americans" and the "foreigners" is found throughout the novel. Even though naturalized, immigrants are still "Bohemians," "Russians," "Norwegians," and so on. They are foreigners in conception as Jim Burden's grandmother says, "If these foreigners [Norwegians] are so clannish, Mr. Bushy, we'll have to have an American graveyard that will be more liberal-minded...."(emphasis mine 73). According to her, the demarcation between foreigners and Americans is purely cultural: as far as foreigners are not clannish and liberal-minded like "Americans... ...an: the heterogeneity within one Bohemian-American family. Children learn Bohemian, the parents' mother tongue, first, and English when they go to school. They eat both American and Bohemian food. Mother from country and father from city, children are open to a wide experience than their parents. Ántonia's first daughter, although married and left the house, is another significant heterogeneity of the family. As the first Mormons scattered sunflowers seeds on their ways to freedom, Ántonia, a woman on the frontier, has raised many future citizens of America. Even though they claimed the end of the frontier, her children might confront another kind of frontier, but it is clear that it is not the same frontier on which their mother has had to stand. The frontier comes back, but always in a different shape.
