Network Coding for Large Scale Content DistributionTypical content distribution solutions are based on placing dedicated equipment inside or at the edge of the Internet. The best example of such solutions is Akamai [1], which runs several tens of thousands of servers all over the world. In recent years, a new paradigm for Content Distribution has emerged based on a fully distributed architecture where commodity PCs are used to form a cooperative network and share their resources (storage, CPU, bandwidth).
Cooperative content distribution solutions are inherently self scalable, in that the bandwidth capacity of the system increases as more nodes arrive: each new node requests service from, and, at the same time, provides service to other nodes. Because each new node contributes resources, the capacity of the system grows as the demand increases, resulting in limitless system scalability. With cooperation, the source of the file, i.e. the server, does not need to increase its resources to accommodate the larger user population; this, also, provides resilience

Therefore, end-system cooperative solutions can be used to efficiently and quickly deliver software updates, critical patches, videos, and other large files to a very large number of users while keeping the cost at the original server low.
The best example of an end-system cooperative architecture is the BitTorrent system, which became extremely popular as a way of delivering the Linux distributions and otherLabel Gallery ActiveX and DDE Programming GuideThe most common method of label print is directly from Label Gallery software using its
GUI (graphic user interface). But sometimes there might be other requirements for label production. Label Gallery has a wide variety of connectivity and integration options so you do not need to use Label Gallery interactively, but through an ActiveX interface or Dynamic Data Exchange connectivity.
Label Gallery can be used as a "print-engine" totally integrated to your custom application and invisible to the end-user eyes.
Basically, the end user sees only your custom application that connects to Label Gallery and uses Label Gallery label printing power in the background.
The purpose of this manual is to show you how you can control the Label Gallery software from your own application that will be deployed to the end-user. Everything you must know about integration of Label Gallery into your application is described in this manual. The information in this manual is for advanced users and application developers only. If you do not plan to write applications that use integrated Label Gallery to print labels, you can skip reading this manual entirely. If you are interested in Label Gallery connectivity and integration options in general, please refer to the White Paper covering these options. You can download the White Paper from Label Gallery website at http://www.satoworldwide.com/labelgallery/index.htm.

It also reports the experience gained while restructuring and enhancing a shared source compiler. Here we describe a general global view of this project, named CAMEO. The initial aim of CAMEO is to implement AspectJ like language support enabling aspect-oriented modularization in C#. Other goals include support for structural aspects that harness Common Language Runtime (CLR) features [1], incremental or partial aspect weaving, and configurable advice weaving. A preliminary source-to-source translator implementation is available for internal use. We intend to evolve this framework for exploring new ideas in AOP and metaprogramming.
Determining a collection of joinpoints in the base source involves performing a detailed control flow analysis of the code. Conducting flow analysis directly on the source text is an expensive operation in most practical cases. Since traditional compilers routinely parse source text and build Abstract Syntax Graphs (ASGs), it makes sense to make use of available infrastructure from implemented translators. In the CAMEO project, we counted on Microsoft’s Shared Source Common Language Infrastructure (SSCLI) implementation to meet these requirements.
SSCLI [2] is an implementation of Microsoft’s CLR architecture. Apart from the implementation of a Virtual Execution Engine and host of other tools, it includes C++ implementation of a C# language translator. The latter is a complete implementation of the ECMA standard [3] and its source code is available for modifications only for academic and research purposes. The SSCLI provided compiler generates Microsoft’s Intermediate Language (MSIL) code. BecauseKeyimage Ontologization & Folksonomy in Web 2.0 Social SpaceThe Age of Image predates and is currently contemporaneous with the Information Age. In our times the explosive expansion of Web 2.0 Social Space, typified by the phenomena of De.licio.us, Flickr, MySpace, YouTube…, and the concomitant emergence of folksonomy, present interesting challenges in the management of this information. One key process by which to accomplish this in Social Space, is the wedding of folksonomy (of the people) with ontology (of the machine). Such a wedding must necessarily be conducted in the shared physicality of the word, of language. In this respect, WordNet together with OWL, play the role of matchmaker. But the same Social Space also provides an opportunity for natural folksonomical tagging by digiFoto (key)image.
The research harness for experimental keyimage tagging consists of Flickr as the main (digiFoto image) Social Space testbed and De.licio.us as the auxillary outreach secondary Social Space. Protégé Editor with OWL-DL provides the support for the bridge from keyimage to the formal ontology. The primary end user application domain is the keyimage tagging of paintings in an online art gallery.
BackStory
The research work reported on here is firmly situated within the emerging field of the Digital re-Discovery of Culture (DrDC) (Sotirova, 2005). Taking image (painting, photograph, publicity image (Berger, 1972, p. 129), television, film…) as typical focal point for (post)modern culture, we explore to what extent one can be lead to an experience of personal «physicality of soul» (FoS) in a playful way, an entertaining way, perhaps through a purposeful designed game (DrDCg) on theAn Architecture for Internet Data TransferThis paper presents the design and implementation of DOT, a flexible architecture for data transfer. This architecture separates content negotiation from the data transfer itself. Applications determine what data they need to send and then use a new transfer service to send it. This transfer service acts as a common interface between applications and the lower-level network layers, facilitating innovation both above and below. The transfer service frees developers from re-inventing transfer mechanisms in each new application. New transfer mechanisms, in turn, can be easily deployed without modifying existing applications.
We discuss the benefits that arise from separating data transfer into a service and the challenges this service must overcome. The paper then examines the implementation of DOT and its plugin framework for creating new data transfer mechanisms. A set of microbenchmarks shows that the DOT prototype performs well, and that the overhead it imposes is unnoticeable in the wide-area. End-to-end experiments using more complex configurations demonstrate DOT’s ability to implement effective, new data delivery mechanisms underneath existing services. Finally, we evaluate a production mail server modified to use DOT using trace data gathered from a live email server. Converting the mail server required only 184 lines-of-code changes to the server, and the resulting system reduces the bandwidth needed to send email by up to 20%.

And without expert guidance and concurrent design-pattern description, they're expected to occasionally fail. Thus providing significant examples and paradigms for teaching good and correct style is of prime importance.
Learning concurrency paradigms is necessary but it is not sufficient. The choice of the run-time semantics must be known since it may introduce subtle design and programming errors. It is the aim of this paper to exemplify the importance of process queuing and awaking policies (whether processes are named threads or tasks) resulting from possible choices of the monitor concept implementation.
The languages Java, C# and Ada implement the monitor concept [Hoare 1974]. Several possible monitor concurrency semantics have been used in the past and a classification is presented in [Buhr1995]. Every implementation provides mutual exclusion during the execution of a distinguished sequence (synchronized method in Java, lock in C#, protected object subprograms in Ada) using a lock for every object. The semantics differ in the chosen policies for blocking, signalling and awaking processes.
The Java policy uses explicit self-blocking and signalling instructions. It provides “wait()”,“notify()” and “notifyAll()” clauses with a unique waiting queue per encapsulated object (termed “synchronized”). A self-blocking thread joins the waiting queue and releases the object mutual exclusion lock. A notifying thread wakes upMicrosoft PowerPoint XP Tutorial pdfThe Basics, Part 1: Creating a Series of Slides

Download Microsoft PowerPoint XP Tutorial pdfInformed Spatial Decision Making Using Coordinated ViewsDecision making is one of people’s usual activities since situations that require making decisions constantly arise in their everyday life. Very often, however, the dimensionality and complexity of decision problems reach far beyond human’s capabilities while the cost of a poor decision may be rather high. Therefore, there is a need in software support to the decision making process, and, in response, a wide variety of software tools, from tools for building graphs and charts to expert systems and intelligent agents, are offered as decision support systems. The reason for this variety is the compound, multi-faceted nature of the decision making process.
The most widely accepted generalisation of the decision-making process was introduced by Simon [25], who divided the process into three major phases: intelligence, design, and choice. The intelligence phase involves data collection, integration, pre-processing, and exploration with the aim to identify the problems or opportunities. During the design phase, one looks for a set of possible solutions to the problem(s) identified in the intelligence phase and analyses the options thus found. During the choice phase, the options are evaluated and analysed in relation to others, and a particular option or a set of options is selected. Typically, a decision-maker must account for multiple, often conflicting, evaluation criteria, and the final decision results from an explicit or implicit trade-off. At any point in the decision-making process, it may be necessary to loop back to an earlier phase.
Malczewski [20] mentions the software tools that can support the decision process at the
