Cognitive resource-aware web service selection in mobile computing environments

Angel Jimenez-Molina, In-Young Ko
2014 Proceedings of the 23rd International Conference on World Wide Web - WWW '14 Companion  
To deal with this problem we propose a service selection method based on two theories from cognitive psychology.  ...  Additionally, a service binding and scheduling algorithm ensures less cognitively-taxing mobile service compositions.  ...  We define a service concurrency as a collection of time-shared abstract services in a parallel construct.  ...

(2) select(j): what is the j-th smallest item in S? and (3) member(k): is k an item in S? We use a popular data-aware method called gap encoding for space compression.  ...  To address the above problems, we plan to develop solutions to several fundamental problems in privacy-preserving data integration and sharing, including (1) a privacy framework that is flexible and clear  ...

A Performance Study of Clustering Web Application Servers with Distributed JVM

King Tin Lam, Yang Luo, Cho-Li Wang
2008 2008 14th IEEE International Conference on Parallel and Distributed Systems  
This paper presents a new generic clustering approach based on DJVMs that promote user transparency and global object sharing for web application servers.  ...  We port Apache Tomcat to our JESSICA2 DJVM and study the performance of a wide range of web applications running on the server.  ...  Users need to manually specify shared classes as distributed shared objects (DSOs) and their cluster-aware concurrency semantics.  ...

Reusable Awareness Widgets for Collaborative Web Applications – A Non-invasive Approach [chapter]

Matthias Heinrich, Franz Josef Grüneberger, Thomas Springer, Martin Gaedke
2012 Lecture Notes in Computer Science  
Creating awareness about other users' activities in a shared workspace is crucial to support efficient collaborative work.  ...  To validate our approach, we demonstrate the integration of three developed awareness widgets in four collaborative web editors.  ...  As mentioned before, compatibility with the majority of web applications has to be ensured in order to devise a reusable solution.  ...

Exploiting distributed version concurrency in a transactional memory cluster

Kaloian Manassiev, Madalin Mihailescu, Cristiana Amza
2006 Proceedings of the eleventh ACM SIGPLAN symposium on Principles and practice of parallel programming - PPoPP '06  
In this DMV configuration, a version-aware scheduling technique distributes the read-only transactions across the slaves in such a way to minimize version conflicts.  ...  DMV's key novelty is in exploiting the distributed data versions that naturally occur in a replicated cluster in order to avoid read-write conflicts.  ...  The allocate dtmemory operation allocates shared memory space of a required size in the transactional memory. The memory allocation scheme is similar to the one in TreadMarks [4] .  ...

A taxonomy for multimedia service composition

Klara Nahrstedt, Wolf-Tilo Balke
2004 Proceedings of the 12th annual ACM international conference on Multimedia - MULTIMEDIA '04  
Service-based architectures, like researched in the Web community, form a possible solution to this problem: The service-based paradigm decomposes complex tasks into smaller independent entities (e.g.  ...  Web services), and then supports a flexible service composition in a variety of ways.  ...  We are aware that the overall service composition problem space is huge.  ...

Data caching as a cloud service

Gregory Chockler, Guy Laden, Ymir Vigfusson
2010 Proceedings of the 4th International Workshop on Large Scale Distributed Systems and Middleware - LADIS '10  
For example, a cloud provider could offer a tenant to lease a dedicated share of 1 MB of space in the data cache for a fixed fee without regard for the utilization of this chunk.  ...  A second observation is that adding tenant-awareness to a data cache can improve the overall hit rate of the cache.  ...
