July 15, 2000 SEEING EAR THEATRE JMS' First Audio Drama for The
July 15, 2000 SEEING EAR THEATRE JMS' first audio drama for the Seeing Ear Theatre premiered on Monday night. "The Damned Are Playing at Godzilla's Tonight" - featuring Steve Buscemi launched a 13-week series by JMS of 30 minute dramas at the Sci-Fi Channel’s website. "Rolling Thunder" - featuring Andre Braugher will be available next week.at http://www.scifi.com/set. The dramas are very much like the original radio format and I think you will enjoy the story. You'll need Real Audio loaded to listen. KEEPING UP WITH CAST AND CREW In the latest issue of TV Zone, we get our first glimpse of Marjean Holden in her new role as Atrina on "Beastmaster". We won't be seeing her episodes for a while, but she says "My character is a bit of a bad girl." Quite a change from her role as Dr. Chambers in Crusade. Ranger Bridgitte reports that: Goran Gajic (married to Mira Furlan and director of episodes like "All My Dreams Torn Asunder") recently directed an episode of "OZ", the awarding-winning prison drama produced by Levinson/Fontana. Goran's episode titled, "The Bill Of Wrongs" premieres on Wednesday July 26 on HBO. The episode will be shown several times throughout the week. A schedule of times is posted at: http://mirafurlan.simplenet.com/ozschedule.html GROUP PROJECT As Babylon 5 approaches it's premiere date on the Sci-Fi Channel of September 25, I wonder what resources we could make available to NEW Babylon 5 fans! When the show was on the air, there was a very active on-line community, the Official B5 magazine came out to provide us with information to digest and enjoy, the series would turn up in publications so that we could read about our favorite characters/actors. -
EFFICIENT ROUTING PROTOCOL in DELAY TOLERANT NETWORKS (Dtns)
Degree Programme in Communication Engineering MORTEZA KARIMZADEH EFFICIENT ROUTING PROTOCOL IN DELAY TOLERANT NETWORKS (DTNs) MASTER OF SCIENCE THESIS Examiners: Prof. Yevgeni Koucheryavy Dr. Dmitri Moltchanov Examiners and topic approved in the Computing and Electrical Engineering Faculty Council meeting on 6th April, 2011 II Abstract TAMPERE UNIVERSITY OF TECHNOLOGY Master’s Degree Programme in Information Technology, Department of Communication Engineering Karimzadeh, Morteza: Efficient Routing Protocol in Delay Tolerant Networks (DTNs) Master of Science Thesis, 47 pages May 2011 Major: Communication Engineering Examiners: Professor Yevgeni Koucheryavy and Dr. Dmitri Moltchanov Keywords: Delay Tolerant Networks, Opportunistic networking, Forwarding mechanism, Routing protocol, Epidemic routing, Network coding Modern Internet protocols demonstrate inefficient performance in those networks where the connectivity between end nodes has intermittent property due to dynamic topology or resource constraints. Network environments where the nodes are characterized by opportunistic connectivity are referred to as Delay Tolerant Networks (DTNs). Highly usable in numerous practical applications such as low-density mobile ad hoc networks, command/response military networks and wireless sensor networks, DTNs have been one of the growing topics of interest characterized by significant amount of research efforts invested in this area over the past decade. Routing is one of the major components significantly affecting the overall performance of DTN networks in terms of resource consumption, data delivery and latency. Over the past few years a number of routing protocols have been proposed. The focus of this thesis is on description, classification and comparison of these protocols. We discuss the state-of- the-art routing schemes and methods in opportunistic networks and classify them into two main deterministic and stochastic routing categories. -

Clark Designs for an Internet Status is version of the book is a pre-release intended to get feedback and comments from members of the network research community and other interested readers. Readers should assume that the book will receive substantial revision. e chapters on economics, management and meeting the needs of society are preliminary, and comments are particularly solicited on these chapters. Suggestions as to how to improve the descriptions of the various architectures I have discussed are particularly solicited, as are suggestions about additional citations to relevant material. For those with a technical background, note that the appendix contains a further review of relevant architectural work, beyond what is in Chapter 5. I am particularly interesting in learning which parts of the book non-technical readers nd hard to follow. Revision history Version 1.1 rst pre-release May 9 2016. Version 2.0 October 2016. Addition of appendix with further review of related work. Addition of a ”Chapter zero”, which provides an introduction to the Internet for non-technical readers.

It is a picture of the Memorial to the Mur- dered Jews of Europe, in Berlin, which I photographed in 2006. -
Official Rulings
BABYLON 5 CCG OFFICIAL RULINGS 1. TURN OVERVIEW • No step in the turn sequence is voluntary. For instance, you cannot voluntarily skip the victory check in order to try to win a major victory by getting 10 or more power than another player. 2. READY ROUND 2.1 Ready Cards (Step 1): • Sustaining can only be done if: There was no cost for the action to be sustained other than rotating the card in question. All necessary requirements for the initiator and the target are still fulfilled. The action being sustained increases an ability of a Character or fleet or the text “while rotated” is on the sustaining card. Also, there is no end of turn gap in the effect. Any ability that is being aided is continuously aided, even if the card providing the aid has the phrase "until the end of the turn" on it. • A sustainable effect is automatically sustained if the Character/Group cannot ready. 2.2 Restore Influence (Step 2): 2.3 Determine Initiative (Step 3): • When determining initiative, you take into account damage to the ambassador for the purposes of comparing abilities. If two ambassadors are neutralized (i.e. all abilities considered to be 0) you determine initiative randomly. Amount of severe damage does not matter for this determination. You can sustain with an assistant to increase the ambassador's abilities for initiative determination, though you cannot do this to a neutralized ambassador 3. CONFLICT ROUND 3.1 Declare Conflicts (Step 1): • You can never target yourself with a Conflict. [Exception: Euphrates Treaty] If the Conflict provides a benefit to you without directing an effect at an opponent, it will not have you select a target. -

A Magyar Babylon 5 Klub kiadványa Ez az elődeink hangja, akik rajtunk keresztül szólalnak meg; És az utódaink hangja, akik arra várnak, hogy megszülethessenek. Ez egy halk hang, amely azt mondja: Összetartozunk. A különbö ző vérünk, a bőrszín, a vallás, a szülőbolygó ellenére, mind Egyek vagyunk. A fájdalom, a sötétség, a veszteségek, a félelem e llenére is, Egyek vagyunk. Mi, akik egy közös cél érdekében egyesültünk, ezennel kijelentjük, hogy Az egyetlen igazság és az e gyetlen törvényünk mindig emígy hangzik: A legfontosabb parancsolatunk, hogy szeressük egymást, Legyünk jók egymáshoz. Minden egyes hang gazdagít minket, és minden egyes elveszett hang gyengít minket. Mi vagyunk az univerzum hangja, a teremtés lelkei; A tűz, amely megvilágítja utunkat a jobb jövő felé.

This began with point-to-point communication between mainframe computers and terminals, expanded to point-to-point connections between computers and then early research into packet switching. Packet switched networks such as ARPANET, Mark I at NPL in the UK, CYCLADES, Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of protocols. The ARPANET in particular led to the development of protocols for internetworking, where multiple separate networks could be joined together into a network of networks. In 1982 the Internet Protocol Suite (TCP/IP) was standardized and the concept of a world-wide network of fully interconnected TCP/IP networks called the Internet was introduced. -

Syllabus – Internet and Web Journalism
Syllabus – Internet and Web Journalism 1. Internet –Introduction, History, evolution and development, The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to research commissioned by the federal government of the United States in the 1960s to build robust, fault-tolerant communication with computer networks. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. The funding of the National Science Foundation Network as a new backbone in the 1980s, as well as private funding for other commercial extensions, led to worldwide participation in the development of new networking technologies, and the merger of many networks. The linking of commercial networks and enterprises by the early 1990s marks the beginning of the transition to the modern Internet, and generated a sustained exponential growth as generations of institutional, personal, and mobile computers were connected to the network. Although the Internet was widely used by academia since the 1980s, the commercialization Incorporated its services and technologies into virtually every aspect of modern life. Most traditional communications media, including telephony, radio, television, paper mail and newspapers are reshaped, redefined, or even bypassed by the Internet, giving birth to new services such as email, Internet telephony, Internet television, online music, digital newspapers, and video streaming websites. -
