Using XDAQ in Application Scenarios of the CMS Experiment
XDAQ is a generic data acquisition software environment that emerged from a
rich set of of use-cases encountered in the CMS experiment. They cover not the
deployment for multiple sub-detectors and the operation of different processing
and networking equipment as well as a distributed collaboration of users with
different needs. The use of the software in various application scenarios
demonstrated the viability of the approach. We discuss two applications, the
tracker local DAQ system for front-end commissioning and the muon chamber
validation system. The description is completed by a brief overview of XDAQ.Comment: Conference CHEP 2003 (Computing in High Energy and Nuclear Physics,

A Framework to Manage the Complex Organisation of Collaborating: Its Application to Autonomous Systems
In this paper we present an analysis of the complexities of large group
collaboration and its application to develop detailed requirements for
collaboration schema for Autonomous Systems (AS). These requirements flow from
our development of a framework for collaboration that provides a basis for
designing, supporting and managing complex collaborative systems that can be
applied and tested in various real world settings. We present the concepts of
"collaborative flow" and "working as one" as descriptive expressions of what
good collaborative teamwork can be in such scenarios. The paper considers the
application of the framework within different scenarios and discuses the
utility of the framework in modelling and supporting collaboration in complex
organisational structures
Irrigation Water Value Scenarios for 2015: Application to Guadalquivir River
This paper reviews the application of a scenario for the 2015 agricultural policy and markets for the irrigated agriculture in Europe. Scenarios for irrigated agriculture 2015 are also described in detail including Reformed CAP and biomass demand. It is applied at the basin level for the Guadalquivir River in southern Spain. The methodology is based upon residual value of water and it combines budget and farm analysis at municipality level, with the Guadalquivir basin divided at 50 âcomarcasâ; in each of them 24 possible crops are selected with specific âcomarcaâ data bases. The 2015 scenario studies the present level of water use and value, and makes an analysis for 2015.This model allows the knowledge of water value and irrigated agriculture at âcomarcaâ level and âaggregated basin levelâ.Water pricing, Irrigated agriculture, Value of water, Scenario analysis, Agricultural and Food Policy, Land Economics/Use, Resource /Energy Economics and Policy,
Proof-of-Concept Application - Annual Report Year 2
This document first gives an introduction to Application Layer Networks and subsequently presents the catallactic resource allocation model and its integration into the middleware architecture of the developed prototype. Furthermore use cases for employed service models in such scenarios are presented as general application scenarios as well as two very detailed cases: Query services and Data Mining services. This work concludes by describing the middleware implementation and evaluation as well as future work in this area. --Grid Computing
A mixed lepto-hadronic scenario for PKS 2155-304
The models developed to describe the spectral energy distribution (SED) of
blazars can be divided into leptonic or hadronic scenarios, according to the
particles responsible for the high-energy component. We have developed a new
stationary code which computes all the relevant leptonic and hadronic
processes, permitting the study of both leptonic and hadronic scenarios in a
consistent way. Interestingly, mixed lepto-hadronic scenarios (in which both
components contribute to the high energy emission) naturally arise in this
framework. We present the first application to the well known BL Lac object PKS
2155-304.Comment: 4 pages, 1 figure; to appear in the proceedings of the Gamma 2012

Mobile, collaborative augmented reality using cloudlets
The evolution in mobile applications to support advanced interactivity and demanding multimedia features is still ongoing. Novel application concepts (e.g. mobile Augmented Reality (AR)) are however hindered by the inherently limited resources available on mobile platforms (not withstanding the dramatic performance increases of mobile hardware). Offloading resource intensive application components to the cloud, also known as "cyber foraging", has proven to be a valuable solution in a variety of scenarios. However, also for collaborative scenarios, in which data together with its processing are shared between multiple users, this offloading concept is highly promising. In this paper, we investigate the challenges posed by offloading collaborative mobile applications. We present a middleware platform capable of autonomously deploying software components to minimize average CPU load, while guaranteeing smooth collaboration. As a use case, we present and evaluate a collaborative AR application, offering interaction between users, the physical environment as well as with the virtual objects superimposed on this physical environment
