AN APPROACH FOR RDF INDEXING AND QUERY PROCESSING February 21, 2014 Rajesh Kannan - 16164021 Prudhvi Nalluri - 16163411 Kranthi Reddy - 12366438 V.Y.V. Akhilesh - 16165666 Overview RDF (Resource Description Framework) is used for describing the resources on the web. It provides structured, machine – understandable metadata for the web. The statements on resources are formed in the form of subject-predicate-object (triples), which can be represented as labeled graphs. SPARQL is the query language for RDF. It provides the standard format and rules for writing and processing queries on RDF data set and the results can be results sets or RDF graphs. The Objective We are provided with the large RDF dataset and will be given a collection of SPARQL queries to fire on the dataset. Our aim is to implement a new approach for query processing and get the results same like getting the result through standard SPARQL query processor. Jena is a framework for java used for semantic web and it’s open source. Main use of Jena is to write the data to and read the data from RDF graph. The main purpose of this project is to design and implement a RDF storage mechanism to store data with good performance and scalability. The Opportunity Many approaches have been proposed to retrieve the data from NoSQL database such as vertical partitioning approach, RDF-3X, Matrix Bit, Bit Mat, etc. We will use vertical partitioning approach because of its performance technique and it was proved to be effective in variety of applications like biomedical data, data warehousing and for taxonomic data. We have lot of NoSQL databases to use such as MongoDB, Cassandra, Hbase, Couchbase, Etc. We are going with Cassandra, which is an open source database and there will be ... ...thms are not mandatory for this approach. Cassandra Pros †¢ Cassandra has all the advantages of the NoSQL. It does not use the relational model, which is required to maintain complex relationships as seen with current relational database systems. †¢ Cassandra is designed to be distributed and scalable, So Cassandra can support massive amount of data spread across multiple servers and also Cassandra is an open source. †¢ Cassandra is decentralized system and also works well in clustered and cloud environment.

Literary Analysis Essay -- Essays Papers

Literary Analysis In James Joyce’s Dubliners, Joyce writes about difficulties and hardships of the Irish people during the 19th century. In the stories â€Å"The Sisters† and â€Å"The Dead,† the separation of an individual from the rest of society is portrayed through many occurrences of eyes and visions. There are many examples that run though out these stories that can be interpreted. Some of these examples can range from being on a symbolic level to an emotional level within the characters. In â€Å"The Sisters,† there are many emotional changes that are a result of visions through certain objects. After the little boy in â€Å"The Sisters† sees the flowers in the store, he goes through a rollercoaster of emotions (3-4). He begins to realize how his feelings are different from all of the other people about the death of the priest. The boy feels a sense of liberation due to the death of the priest (4). He is upset and annoyed by this and does not know what to do with this emotion. Being put through the death of his best friend the priest, he would change his view on life. He started out in the beginning of the book as just a normal boy, but towards the end he took a new perspective on everything. During the story â€Å"The Dead,† the vision Gabriel has at the end of the story makes him go through an emotional change. In the story, after the main character Gabriel learns about his wife’s past love (221-222), he looks out the window and stares at the snow for a little bit and then starts to cry. His emotions have taken over him as he is now thinking differently about everything he had every thought of. The previous feeling of how lovely his wife is and how he was looking forward to being with her... ...ead,† Gabriel questions many things including himself. After hearing his wife explain her sadness about her past, Gabriel looks out the window to see the dark snowy night. He questions his own role as a husband to his wife. He questions his role in society also. He does not have any answers for these questions. So he then goes to bed as his soul fades away. All of these examples show the separation of an individual from the rest of society. Joyce words stories so well that the separation can be shown through simple visions throughout the stories in â€Å"Dubliners.† To recognize these themes in the stories gives the reader a better understanding of what is going on. They can actually connect with what the main character is feeling or at least have an idea of what is unfolding. These themes bring the sad truth to us in a beautiful well written manner.

Fall of Usher :: essays research papers

"The Fall of the House of Usher" Summary The narrator approaches the House of Usher on a "dull, dark, and soundless day." This house--the estate of his boyhood friend, Roderick Usher--is very gloomy and mysterious. The narrator writes that the house seems to have collected an evil and diseased atmosphere from the decaying trees and murky ponds around it. He notes, however, that although the house itself is decaying in pieces (for example, individual stones are disintegrating), the structure itself is fairly solid. There is only a small break in the front of the building from the roof to the ground. The narrator reveals that he is to stay in this house because his friend, Roderick, sent him a letter earnestly requesting his company. Roderick told the narrator in this letter that he was feeling bodily and emotionally ill, so the narrator rushed to his house. The narrator also mentions that the Usher family, while an ancient clan, never flourished. Only one member of the Usher family survived from generation to gener ation, so they were all in a direct line of descent without any siblings. The inside of the house is just as spooky as the outside. The narrator makes his way through the long passages and to the room where Roderick is waiting. The narrator notes that his friend is paler and less energetic than he once was. Roderick tells the narrator that he suffers from nerves and fear. His senses are heightened. The narrator also notes that Roderick seems afraid of his own house. Further, Roderick's sister, Madeline Usher has taken ill with a mysterious illness that the doctors cannot even identify. The narrator proceeds to spend several days trying to cheer Roderick. He listens to Roderick play the guitar (and makes up words for his songs), he reads to Roderick, he sits with him for hours. Still, he cannot lift his sadness. Soon Roderick posits his theory that the house is unhealthy, just as the narrator had supposed at the beginning of the story. Soon, Madeline dies, and Roderick decides to bury her temporarily in the tombs below the house. He wants to do this because he is afraid that the doctors might dig up her body for scientific examination (since her disease was so strange to them). The narrator helps Roderick put the body in the tomb. He notes that she has rosy cheeks, as some do after death.

Palace of Industry in Paris France Essay -- Architecture History

missing images Paris 1855: The Universal Exposition Interior and Exterior of the Palace of Industry These selected images, an exterior view of the Palace of Industry and a view of the interior of the palace during the distribution of awards, are both detailed views from which much can be observed. Since both images are illustrations, as opposed to photographs, they may not be entirely accurate. The image of the interior is a lithograph, which is approximately thirty-five inches by fifteen inches. Because of the medium employed, the details of the image are not very sharp, but many details are included. Emperor Napoleon III can be seen handing out the awards, and his empress is seen seated behind him. The other image appears to have been taken from a French newspaper article. Today, the actual paper is very old, as can be evidenced by the large tear in the middle of the picture and its worn edges. The actual size of the illustration is about fifteen inches long and eight inches wide. Most significant about the Palace of Industry are its historical precedents, the evolution of its de sign, its successes and failures, and finally its role at the fair. After London hosted the first international exposition in 1851, Napoleon III realized that France needed to seize back the initiative. The motive given for the 1855 Paris exposition was to celebrate forty years of peace in Europe since Waterloo (Findling, pp. 16-17). A hidden agenda, however, was the competition among the major European nations, to establish their industrial and artistic supremacy. Napoleon III decided that France needed a spectacular structure "based on the plan of the Crystal Palace of London" (Lavedan, p. 228). Therefore, in 1852, France held a competition fo... ...e success of the Palace of Industry, it did nothing to promote the careers of either Viel or Barrault. Regardless, the Palace of Industry was an influential step in the integration of this revolutionary material, iron, with traditional architecture. Bibliography Findling, John E.

Progressivism :: The Progressives

The progressive believed that by applying a more uncorrupt form of democracy they could in fact fix the already corrupt democracy especially at the state and city levels. The progressives believed that if given a chance the majority of voters would elect honest respectable officials unlike those elected by the corrupt political machine but to do this they needed people to vote. So they compiled numerous methods for increasing the participation of the average citizen in political decisions. The secret ballot box, by using the method adopted by the Australians the voter would not be manipulated by the political party that would affect a voters decision by standing next to a ballot box and intimidating him or her. This method was first accepted by Massachusetts in 1888 and proved to be really popular by 1910 all voting states adopted this method. The progressive governor of Wisconsin Robert La Follete introduced the method of direct primaries in which the majority vote would elect the p arty candidates for the state and federal offices. This method was used to try to minimize the power of political bosses to try to keep the corrupt officials from gaining office once again. The direct election of state senators was also a plus for the progressives for many years the senators had been selected by the vote of the state legislature. The corrupt state legislature would then of course vote for the corrupt official for senate. After a while the senate begun to look like a club for the rich man. In 1913 the seventeenth amendment required all that all U.S senators be elected by the popular vote. By calling for Initiative, referendum, and recall the Progressives allowed by initiative to take part in the process of having a legislature pass a bill, to allow voters to vote on proposed laws on their ballots by way of referendum, and finally recall which allowed voters to remove an unsatisfactory politician from office by majority vote before the end of his or her term.

Capitalist Society in The Death of a Salesman by Arthur Miller Essay ex

Capitalist Society in The Death of a Salesman by Arthur Miller "Death of a salesman" is a "tragedy of a common man". Throughout the play the reader sees how Willy Loman struggles to achieve something, which is beyond his capability. He has a dream, the American dream of success and accomplishment. And yet, he is not able to ever thrive because his idea of how to succeed is wrong. The times have changed, the play is set in the period of an economic boom and increasing desire for material goods in America and the Loman family is now living in a capitalist society, however, Willy seems not to have realised that things have changed. He is constantly battling between the present and the past, the reality and a dream. The play is about a conflict between a man and his society, it's a "hanging fire" between suicide and intolerably changing world. To begin with, however, it is important to identify what is meant by the term "capitalist system". Capitalist system is a type of an economy where the owners of the businesses retain all the profits for themselves. This type of a system encourages people to want more, as they hold total responsibility of how much they earn. The importance of the employer and employee relationship increases, as the workers are judged by the quality of the work they are putting into the company. It becomes a tough competition between the staff to survive and keep their jobs. There is now a need to impress on the employer with the effort and work you put into his firm and consequently climb up the ladder of success. The relationship between Howard and Willy in the play is very ambiguous. Howard on one hand is running... ... physically and mentally. He desperately tries to integrate, but he was left behind the modern world. Unable to control his senses of past and present, mixing and confusing the two, Willy fails to see the flawed nature of the system he functions in. He follows wrong dreams and ideas, which are mainly imposed upon him by the society, only to prove himself; nonetheless he is "crushed" by the unjust, competitive culture. And in addition, his personal failures add to the self-perceived wasted life of a "common man". 1. C.W.E.

Krispy Kreme Opportunities 1. Add more stores in current target markets to make it convenient for all areas. 2. Attract a broader range of customers and sell more products to existing customers by enhancing present menu offerings, esp in coffee and coffee drinks. Krispy Kreme Threats 1. Competitors concerned about KK rapid growth and market share gains and erosion of their own market positions, may well be compelled to rejuvenate their product menus, this would be costly battle for KK. 2.
