PERFORMANCE EVOLUTION OF PEER TO PEER NETWORKS

This thesis work concerns about the Performance evolution of peer to peer networks, where we used different distribution technique’s of peer distribution like Weibull, Lognormal and Pareto distribution process. Then we used a network simulator to evaluate the performance of these three distribution techniques.During the last decade the Internet has expanded into a world-wide network connecting millions of hosts and users and providing services for everyone. Many emerging applications are bandwidth-intensive in their nature; the size of downloaded files including music and videos can be huge, from ten megabits to many gigabits. The efficient use of network resources is thus crucial for the survivability of the Internet. Traffic engineering (TE) covers a range of mechanisms for optimizing operational networks from the traffic perspective. The time scale in traffic engineering varies from the short-term network control to network planning over a longer time period.Here in this thesis work we considered the peer distribution technique in-order to minimise the peer arrival and service process with three different techniques, where we calculated the congestion parameters like blocking time for each peer before entering into the service process, waiting time for a peers while the other peer has been served in the service block and the delay time for each peer. Then calculated the average of each process and graphs have been plotted using Matlab to analyse the results

Oscar Wilde’s “The Happy Prince” : The Hidden Messages and the Debate on the Target Audience

Oscar Wilde’s fairytales have been read to children for more than a century. Nevertheless, since the time of their publication in 1888 and 1891, the target audience of The Happy Prince and Other Tales and A House of Pomegranates have been the concern of critics. Delving into the context behind the rich and colourful imagery, one can find implications of homosexuality, the Paterian aesthetic and religious connotations. According to Carol Tattersall, The Happy Prince and Other Tales successfully mislead the public that it is innocent of any intention to undermine established standards of living or writing. Tattersall’s argument is based on comparing the first collection to Wilde’s second, A House of Pomegranates, which was perceived as “offensive and immoral” (136). On the other hand, William Butler Yeats states in his introduction to The Complete Works of Oscar Wilde that overall the reviewers of The Happy Prince and Other Tales were hostile because of Wilde’s aesthetic views (ixxvi). But Yeats overlooks the fact that Wilde was very pleased and proud, dashing notes to friends and reviewers and signing copies to many people (Tattersall 129). In general, the reception of Wilde’s first collection was more positive than that of the second because it was milder and more subtle in its controversial themes.

Barn och föräldrars val av bilderbok med fokus på illustrationer : En intervju- och observationsundersökning

Syftet med denna studie var att dels jämföra barn, 3–6 år, och föräldrars preferenser av barnboksillustrationer, dels att undersöka hur föräldrar resonerar kring val av bilderbok och illustrationens roll i samband med detta. Genom enskilda semistrukturerade intervjuer och tillhörande observationer med 22 barn (3–6 år) och 10 föräldrar undersöktes vilken av fem typer av bokillustrationer som föredrogs. Föräldrarna fick därefter även välja vilken av fem bilderböcker, från vilka illustrationerna var hämtade, som de skulle vilja läsa för sina barn och motivera sitt val. Resultatet från undersökningen tyder på att illustrationerna är en aspekt för både barn och föräldrar vid val av bilderbok samt att det finns faktorer som föredras i illustrationerna. Barnen i undersökningen verkade föredra naivistiska illustrationer med stort antal fokuspunkter. Föräldrar föredrog realistiska illustrationer med inslag de kan koppla till verkliga livet. Föräldrarna ansåg att illustrationer, handling, moral och lärdom var viktiga aspekter vid valet av bilderbok till deras barn. Flertalet föräldrar ville ha möjlighet att berätta egna historier kring illustrationerna i bilderboken.
