Business Semantics on top of Process Technology

Details :


The BSopt project will deliver an integrated methodology for inter-organizational systems spanningfrom business models over business process models to their execution in a service-orientedarchitecture (SOA). Integrating business processes into a SOA is certainly a hot topic. However, mostcurrent approaches are limited to the technical process aspects, disregarding the economic drivers ofthe information society. In contrary, BSopt will consider the formalization of the semantics of newbusiness models due to faster changing business environments, their support by appropriate businessprocesses and their implementation in flexible architectures. We will incorporate state-of-the-artapproaches to describe business models, business process models and deployment artifacts inSOAs. However, we will go beyond the state-of-the-art by connecting the dots between theseapproaches allowing for a semi-automatic mapping between them.This will result in an integrated methodology spanning over all layers that is based on a metamodel incorporating the semantics of the assimilated approaches. Furthermore, we demonstrate thecustomization of the BSopt approach by integrating a domain (= industry) specific ontology by meansof the print media industry. A critical point in reaching user acceptance is tool support for the BSoptmethodology. Following advanced software engineering concepts, we will implement the integratedBSopt approach as a software factory based on a so-called domain specific language (DSL). For thispurpose we have to use a meta-modeling tool, that allows us to specify the BSopt meta model withinthis tool. Furthermore, the software factory will guide a modeler in a wizard-driven style through theBSopt methodology requiring not as much modeling know-how as in traditional modeling languagessuch as UML. The meta-modeling tools being used in BSopt are the Microsoft DSL tools for VisualStudio and ADONIS.The goal of a software factory-based approach is creating high quality code in shorter time. Codecreated by the BSopt tools are deployment artifacts (BPEL, WSDL, XAML,etc..) to be consumed byexisting software environments¿ in our case the Oracle SOA Suite and the Microsoft Workflow Foundation. The BSopt approach will be validated by case studies in the print media industry.

Cloud Powered IT as an Energy Efficiency Enabler: A feasibility Study for Austrian public sector

Details :


The accumulation of greenhouse gases in the atmosphere is growing in an alarming rate and the goals declared in the Kyoto protocol are far away. The role of Information and Communication Technologies (ICT) is undoubted for reducing CO2 emissions. This role is recognized by scientific community, international bodies and national and international policy makers. The direct footprint of ICT amounts for 2%-3% of total global emissions and 10% of emissions in OECD-countries. ICT offers a huge energy efficiency potential across the economy and can deliver emissions savings up to 15%. As 75% of ICT footprint is due to its usage, optimization of usage is the area that must receive the most attention. ICT is a contributor to CO2 emissions and global warming but more importantly it is a key technology for fighting against global warming. The key enabling technology for achieving energy efficiency and resource optimization is Cloud computing which are centralized and highly scalable services that could lead to further capacity to virtualize or consolidate resources with breakthrough gains in energy efficiency. Underutilization is the main reason for energy inefficiency of current local solutions. Most of the servers are consuming energy but are utilized under 6%. In other words, the energy is consumed but 94% of resources are wasted. In public sector the situation is not different. According to Vivek Kundra, the CIO of the USA, federal servers are utilized about 7%. Even at a very low load the power consumed is about 50%-70% of the peak power. This utilization rate and subsequently the energy consumption can be improved significantly by Cloud technology. Imagine the energy saving of a single fully utilized server instead of 16 servers, each 6% utilized. Because of this impact the European Network and Information Security Agency (ENISA) has identified Cloud computing as a high priority research area. The international trend is also clear. More and more companies such as AOL, Starbucks, Canon and providers of renewable energy such as blueEnergy are turning to Cloud. One of the major application areas of Cloud technology is public sector. The Obama administration and other governments in Germany, Switzerland, UK, Japan, Taiwan and Korea as well some other countries have recognized this opportunity and are pushing the Cloud agenda forward, not only because of its cost saving potentials but also because of its impact on the environment. This potential has been recognized in Austria but unfortunately actual steps have not yet taken. Lacking actual steps means risk of losing technological competitiveness and the strategic markets of tomorrow. Public sector has requirements such as reliability, availability, business continuity and data security and therefore is a representative case for other sectors.In this project we envision to conduct a feasibility study for Cloud powered Austrian public sector in order to make the first steps in the right direction. The experiences and results from this project can be applied to other sectors such as finance and heath. The study will not only cover technical issues but also environmental, energy savings and cost reduction issues. This project will evaluate possible applications of Cloud computing in public sector, its costs, energy saving potentials and associated risks in addition to the technical issues. The results can be used as a basis for decision makers to make the right decision and choose the right technology.

CVAST: Centre for Visual Analytics Science and Technology(Laura Bassi Centre of Expertise)

Details :


Due to the proliferating capabilities to generate and collect vast amounts of data and in-formation we face the challenge that users and analysts get lost in irrelevant, or otherwise inappropriately processed or presented information. This phenomenon, commonly known as information deluge, overwhelms traditional methods of data analysis such as spread-sheets, ad-hoc queries, or simple visualizations. At the same time, intelligent usage of increasingly available data offers great opportunities to promote technological progress and business success. On this score, Visual Analytics is an emerging research discipline developing methods and technology that make the best possible use of huge information loads in a wide variety of applications. The basic idea is to appropriately combine the strengths of both, computers'and humans'information processing capabilities. To make complex information structures more comprehensible, facilitate new insights, and enable knowledge discovery, methods of visualization, intelligent data analysis, and mining form a symbiosis with the human user via interactive visual interfaces.The goals of the Centre of Visual Analytics Science and Technology (CVAST) are twofold. The first goal is the integration of the outstanding capabilities of humans in terms of visual information exploration with the enormous processing power of computers to form a pow-erful knowledge discovery environment. The second goal is to scientifically assess the usability and utility of such discovery environments while bridging the gap between theory and practice for selected application scenarios. Application scenarios that involve temporal properties are in the focus of our scientific interest.Time - in contrast to other quantitative data dimensions that are usually"flat"- has an inherent structure and distinct characteristics (calendar aspect, natural and social aspects, etc.) which increase its complexity dramatically and demand specialized Visual Analytics methods in order to support proper analysis and visualization.Our expected results will be + Innovative, user-oriented, and task-specific Visual Analytics methods and tools with an assessment of their usability and utility. These methods will be used inter-twinedly and iteratively to ease the explorative information discovery processes + An appropriate framework for these methods and tools + Their evaluation in"real life"environments and examination of the information dis-covery process within several application scenarios+ A new methodology to define and evaluate insights facilitated by these methods + Applying these methods within commercial applications to illustrate their business value and economic impacts

Development of an Augmented-Reality Dynamic Spatial Test

Details :


In the proposed project we intend to develop a new type of test for theassessment of spatial abilities that differs from conventional spatialability tests in several aspects. First, traditional spatial abilitytests (paper-pencil as well as on-screen computer versions) assess3dimensional spatial abilities with 2dimensional means. The new testwill measure the ability to visualize and mentally manipulate3dimensional objects in actual 3dimensional space, and should thus havea higher ecological validity than previous spatial ability tests. Thiswill be possible through use of the Augmented Reality tool Construct3D,which allows for projecting virtual 3dimensional objects into real spacewhere they can be seen and manipulated by means of special glasses andinput devices.Furthermore, the planned test will be a dynamic learning test; thus,other than conventional tests, it does not only measure a person¿s current status, but also his or her learning potential. Performance in conventional tests is generally, and particularly when spatial abilities are concerned, significantly dependent on factors such as test experience or experience with similar tasks and materials. Gender differences, which arestill frequently found in spatial tests, can partly be attributed to these experience-based factors. Often, such differences can be reduced or eliminated through a relatively short training, sometimes even through a simple re-take of the test. With a dynamic learning test (usually consisting of a pretest, a training phase, and a posttest) the influence of short-term learning experiences on test performance can be assessed, which may yield higher internal consistency and predictive power of the test scores. The new item material will assess the mental manipulation (rotation, combination, intersection, etc.) of 3dimensional objects. Stimuli and instructions are presented sequentially. Hence, in contrast to most other tests, participants need to actually encode and manipulate mental representations of the spatial objects. Thereby, the range of possible strategies (e.g., comparison of singlefeatures and elimination of possible answers) is reduced. In order to guarantee homogeneity of the testing material and to avoid problems such as ceiling effects, item-response-models will be employed for the development of test items as well as for the measurement of change in performance.
