COCTA project proposes coordinated economic measures aiming to pre-emptively reconcile air traffic demand and airspace capacity, by acting on both sides of the inequality. In performing demand-capacity balancing COCTA primarily aims to reduce the cost arising from lack of coordination in the ATM system, stemming both from divorced planning horizons of ANSPs and aircraft operators (AOs), and from an inadequate pricing of navigation services. ANSPs plan their capacities weeks and months in advance, with only very limited and costly possibilities to adjust those on a short notice. On the other side, AOs attach great value to flight planning flexibility and tend to file their route choice decisions only hours before the time of departure. The mismatch between the predictability for ANSPs and flexibility for AOs results in substantial and costly capacity buffers built into ANSP planning decisions. COCTA recognizes this as a major issue and designs mechanisms acting on both sides, to incentivize more cost-efficient outcomes. To make this possible, COCTA envisages a new role for the network manager (NM), supported by re-designed regulatory setting. On capacity side, the NM purchases airspace capacities in line with expected network demand, employing a network-centred, demand driven approach, as opposed to the current, piecemeal and supply-driven practice, which is tailored against local (ANSP) traffic peaks. As a consequence, excessive provision of airspace capacity is to be reduced, with associated cost savings. On the demand side, the NM performs trajectory pricing, offering route menus to AOs, including novel, flexible products, aiming at an appropriate balance between cost-efficiency, delays, environmental impact and equity, without compromising safety. COCTA mechanisms and choice-based mathematical models thus work in a re-designed ATM value chain and optimize multi-criteria objectives, fully complying with multi-dimensional SES policy goals.

Philological research is very much concerned with the idea of data provenance. However, existing provenance models in eResearch and eScience for data and workflow are ill-applicable to the specific challenges of philological research in the digital age. In philology, provenance data must be collected not only for the complete research objects, but also for fragments in particular for texts. This necessitates a much richer provenance model that is interwoven with the objects' textual structure and supports the association of provenance data with individual words. It must also permit multiple interpretations of provenance for a single research object. In this, the requirements in digital philology can also be paradigmatic for very fine-granular provenance information collection in other domain-specific digital ecosystems. This paper elaborates key requirements of data and workflow provenance in the philologies and demonstrates how the tools in the TextGrid digital humanities ecosystem answer to those needs. In addition to TextGrid's text-image-link editor and its underlying data model the paper also introduces the humanities' provenance tool HPT for RESTful workflows. HPT is specifically geared to supporting the provenance requirements for workflows in heterogeneous digital humanities ecosystems. © 2011 IEEE.

This paper reports the findings of a survey on European airlines often categorized as low-cost carriers to see to which extent they have changed their business model towards a hybrid strategy, adopting features of full service network airlines. Data is provided on relative frequencies of attributes of the low-cost business model retained and modified respectively. The survey concludes that short-haul airline business models in Europe converge. A large percentage of low-cost carriers has evolved into hybrid carriers which blend low-cost traits with those of full service network carriers. © 2012 Elsevier Ltd.

This paper examines what current learning systems offer towards the idea of a multi-dimensional learning system. It will show the requirements for a multidimensional learning system and that no current system is able to meet them. Therefore a new model is proposed that is not only capable of fulfilling the requirements for cultural diversity but also of satisfying the rising demand for personalization that has been rising in the course of the last twenty years. This new model will enable systems, which bring the personalization of e-learning to the next level.

The Internet has become mobile. A recent study stated that approximately 54 percent of all online content will be accessed via mobile devices already by the end of 2017. We are informed while shopping on review sites about the scanned product and compare its price among online providers. We find the nearest Italian restaurant based on our current site and complain in real time on social platforms about the over salted potato soup. We check - with a digital gym on the wrist - our running and sleeping behavior and compare our diet results with the rest of the (online) world. Thanks to smart devices our customers are almost continuously online. And they have an unprecedented transparency about what we are doing as a company. In good times as in bad. Therefore, the following contribution explains how our user behavior has changed through the triumph of the mobile Internet and what consequences should attract business from it. It offers specific examples and facts from business and private life based on German stats. © 2014 Infonomics Society.

Nowadays, companies and home users use websites offering services ranging from web sites up to complex web applications. The ergonomics of these applications are an important criterion for their success. This paper presents techniques to gather usage information about a web 2.0 application. With the help of this information, a usability engineer can interpret usability data accurately and improve the chances for adoption of the web application by a wide range of users. © 2010 IEEE.

Information Wants to be a Topic Map: 6th International Conference on Topic Maps Research and Applications, TMRA 2010 | Year: 2010

Topic Maps (TM) is a powerful standard family to describe real world scenarios in computer processable data structures. On one hand it is so generic that arbitrary ontologies can be defined on the other hand this limitless concept brings up some problems when visualising this information to users who are not familiar with Topic Maps. To make TM databases applicable for end users it is necessary to solve the visualising problems of such a generic concept without enforcing limitations to it. This proposal presents the concepts of a description language to be created to design a graphical user interface (GUI) for specific ontologies defined in Topic Maps.

A Cloud Service is usually classified as Infrastructure as a Service, Platform as a Service or Software as a Service. This classification ist not sufficient, when Business Processes are considered. Therefore, Business Process as a Service (BPaaS) as next level of abstraction is in discussion. BPaaS is already an important topic for analysts and cloud providers. In the scientific community a discussion about BPaaS has been started. This contribution presents a literature analysis of the current state-of-the-art in BPaaS. In order to investigate how a Business Process can be built on top of a cloud service, a prototpye of an external application is presented, which is built on top of a cloud service using a RESTful API. For the realization of BPaaS existing architectures for cloud computing are discussed. A proposal for an advanced Architecture for Business Process as a Service is presented. Based on these findings, a brief outlook on future research questions concerning Business Process as a Service is derived.

The lead medium of the humanities is text, but text with special characteristics that can be quite different from a normal monolingual article in most modern scripts. Text that can be derived from manuscripts, from retro digitization of previous scholarly publications such as critical editions and dictionaries, from books printed centuries ago, applying conventions no longer in force today. The keynote identifies four major challenges for recognizing humanities data: Unusual characters, unusual layouts, unusual semantics and unusual segmentations. Each challenge is illustrated with concrete examples taken from a variety of times and places, starting with cuneiform tablets, an extract from a Greek manuscript, a page from a multilingual critical edition, a renaissance print, a lemma from a scholarly dictionary, and some more. In addition, scholarly humanities data is typically marked up using domain-specific rich XML-based formats based on the TEI P5 guidelines. Any format that an OCR program produces must be sufficiently rich to permit for a mapping on TEI-compliant markup in order to be capable of reproducing the full richness of the original. A closer view at the Text Grid virtual research environment for the humanities and its Text-Image Link Editor (TBLE) demonstrates how scholars currently tackle these tasks. It analyzes where automatization can facilitate their task and enable new dimensions of research. © 2011 IEEE.

TextGrid's Text-Image-Link-Editor is used to link segments of text with sections on the corresponding image. A typical application is the linking of scans of facsimiles with their transcriptions, though these texts can also be created during the linking process, which allows also for image annotations. The information on the linking between manuscript fragments and the corresponding transcription is itself stored in TEI P5. TextGrid is a virtual research environment for the humanities disciplines dealing with texts in a wide sense (philologies, epigraphy, linguistics, musicology, art history, etc.). The joint research project TextGrid is part of the D-Grid initiative and is funded by the German Federal Ministry of Education and Research (BMBF) for the period starting from 1 June 2009 to 31 May 2012 (reference number: 01UG0901A). TextGrid consists of two principal building blocks, the grid-based back-end TextGridRep that hosts both infrastructure services and the repository layer for access to research data and long-term archiving, and the user-facing TextGrid Laboratory (TextGridLab). The TextGridLab, a single point of entry to the virtual research environment, provides integrated access to both new and existing tools and services via user-friendly software based on the eclipse framework [TG]. TBLE is a key component of the TextGridLab that has been under continuous development since 2008 and is by now in practical use. © The Author 2013.
