Vision StatementProvide a high level framework for developing high performance applications that can scale linearly with higher resources. AbstractWe live in the world where Moore's law and Von Neumann's model of programming will soon be obsolete. As Dr. Dobb's article ... [More] http://www.ddj.com/web-development/184405990;jsessionid=0LJW3X4MBU5TSQSNDLRSKH0CJUNN2JVN?_requestid=131749 on "Free Lunch is over" indicated we will have to adjust in this world. Fortunately, parallel programming field has been dealing with this for several decades and there are plenty of solutions available. Unfortunately, most of them are still very research oriented and difficult to use in the real world. I wrote similar system called JavaNOW several years ago as a research project in Java that I will port to Erlang. I plan to leverage concurrency capability of Erlang language and its supported libraries such as OTP and provide a framework for writing high performance applications. Though, Erlang is concurrent language and OTP provides sophisticated support for writing fault tolerant services and provides high availability (with hot code swaps), but it does not inherently support writing parallel applications. Erlinda fill in that gap and provide abstraction to write high performance applications. It is built on top of Erlang and OTP and uses RabbitMQ for messaging middleware. IntroductionErlinda provides a framework for writing parallel applications. It provides a number of abstractions for creating parallel applications such as: Tuple Space model based on Linda memory model (JavaSpaces) MPI like APIs for communication (Scatter/Gather) Map/Reduce Master/Slave (Computing Farm) Service oriented (OTP) Clustering Agents and Mobililty Messaging oriented (Queues/Topics) Service/Resource discovery mechanism (similar to JINI) Integration with other languages and middlewares Code Server (similar to JINI/RMI) Security Project OwnerShahzad Bhatti ContactEmail: bhatti AT plexobject.com URL: http://bhatti.plexobject.com Join the ProjectThough, Erlinda is in early phase of development, anyone who wants to get involved is welcome, especially with experience with Erlang/OTP and parallel computing. Any feedback or suggestions is greatly appreciated. [Less]

Este trabalho visa apresentar os conceitos dos protocolos IPv4 e IPv6, além da diferença entre os dois e como é possível utilizá-los em coexistência na mesma rede (através de túneis ou não), ou até na mesma aplicação. Para isto é necessário os conhecimentos fundamentais sobre ... [More] arquitetura de redes, através da demonstração dos modelos OSI e DARPA, ao passo que se possa compreender o estudo dos protocolos e do objetivo a ser realizado. Outro estudo a ser realizado é sobre as redes sem fio do padrão IEEE 802.11, ou WLANs, que compreendem o meio de comunicação para a mobilidade. Tudo isso se faz necessário para que se possa demonstrar as formas padronizadas pela IETF para a realização de mobilidade com cada um dos protocolos, demonstrando-as num âmbito de grandes redes, ou simplesmente em redes locais, como as WLANs. Com isso, será apresentado uma proposta de mobilidade para as redes IEEE 802.11 com protocolo IPv6, baseando-se nos modelos estudados e em algumas propostas já em funcionamento. Esta proposta será comparada com as demais e destacada o seu diferencial. Sendo assim, será testada na prática e relatada neste trabalho para destacar quais os pontos mais importantes. [Less]

scaut

A project for enabling communication for people with speaking and/or mobility problems. It is going to be developed for mobile devices. In fact, final code will be enabled for ipod touch/iphone and Nintendo DS. It will have collaboration capabilites.

hawkingtoolbar

Overview: The Hawking Toolbar is a plug-in for the Firefox web browser that frees individuals with severely limited motor abilities to explore the internet, without limits. Unlike expensive commercial products, it is free and customizable. Published under the open-source GPL license, it can be ... [More] enhanced or customized by anyone with the appropriate technical skills. By using a Firefox plug-in we can deliver a robust product:     * extensibility: it can be enhanced or customized by others     * non-obsolescence: this standard Firefox plug-in will work with any new version of Firefox. The user is not dependent upon developers to upgrade the plug-in for each new web technology or new version of the browser     * standard view: the user sees the same web page as others. This plug-in enhances a popular browser instead of requiring a specialized one! For too many centuries, people with physical disabilities have been treated as inferior by society. Considering that one of the greatest geniuses of our time, physicist Stephen Hawking, lives with a debilitating form of Lou Gehrig's disease and yet continues to live a rich life and makes giant contributions to our understanding of the universe, it is obvious that this unfair treatment hurts all of us. Technology makes it possible for Dr. Hawking to communicate his ideas to us; he shows us that there is no definite correlation between physical ability and the greatness of the human spirit. This toolbar is a small tribute to him and all individuals who face the biggest challenge of all: our own prejudices. [Less]

ieee802154-mobility

Simulador de mobilidade em IEEE 802.15.4O padrão de rede IEEE 802.15.4 vem sendo utilizado como solução adequada para redes de sensores sem fio em muitos ambientes e áreas de atuação. Este tipo de rede tem características específicas que a diferem de outros tipos de rede sem fio. Este ... [More] trabalho visa avaliar o impacto da mobilidade de elementos na rede IEEE 802.15.4. Para isso, foi desenvolvida uma plataforma de simulação que contem os requisitos específicos necessários para avaliar e comparar ambientes com e sem mobilidade. Os resultados vão mostrar que a mobilidade dos elementos nos cenários avaliados provocou degradação do sinal em pequenas distâncias, mas em distâncias entre 30 e 40 metros a mobilidade causou uma melhora na taxa de transmissão dos elementos, assim como em distâncias maiores que 60 metros. Isso se deve pelo fato de que em distâncias intermediárias a rede apresentou alta taxa de colisão entre os pacotes, fazendo com que a técnica CSMA/CA melhore o desempenho da rede em ambientes com maior variabilidade do sinal. IEEE 802.15.4 mobility simulatorThe IEEE 802.15.4 network standard is being used as a suitable solution for wireless sensor networks in many environments and areas of expertise. This kind of network has specific characteristics that differ from others types of wireless network. This work intends to analyse the mobility impact on IEEE 802.15.4 elements. For this reason it was developed a simulation platform that contains specific requirements necessary to evaluate and compare environments with and without mobility. The results will show that the mobility of elements in the scenarios evaluated caused degradation of the signal at short distances, but for distances between 30 and 40 meters in mobility caused an improvement in the rate of transmission of elements, as well as at distances greater than 60 meters.This is due to the fact that at intermediate distances the network presents high rate of collisions , making the technique CSMA/CA improve network performance in environments with more variability of the signal.
