CERO: CE RObots Community
(2005)
We describe our experience creating a robots community using standard hardware and software - the Windows CE operating system, XScale development boards, and LEGO Mindstorm actuators. We focus on an open and extendable distributed robotics system, which in contrast to most existing proprietary robotics systems, supports cost-effective integration and assembly of components while providing dependable communication and coordination. To demonstrate feasibility we have developed the CERO Framework for ad hoc cooperation in robots communities employing a service-oriented architecture with the main building blocks: ad hoc networking for different wireless technologies (e.g., Bluetooth, WLAN, or 433 MHz radio communication), a protocol for interconnecting development board and actuators, and a CE.NET based software framework supporting complex movements, consensus protocols, cooperation, and positioning. It offers high-level interfaces for programming complex tasks in cooperative robotics. We also present an overview of intended applications.
The emergence of the Internet of Services and the Internet of Devices opens new possibilities for societal computung scenarios. Ambient Intelligence (AmI) is a vision of an environment that puts the needs of the user in the center of the technological design process. An AmI environment consists of ubiquitous distributed devices such as sensors, displays, data memories which are embedded in everyday objects like walls, clothes, tables or the pavement. These devices are interconnected and seamlessly deliver applications and services to the user. AmI emphasizes the intelligence of the environments interfaces and the intelligence that can be achieved by correlating context information from different data sources. In this work we present an approach to transfer the AmI vision to the public services sector using the paradigm of service orientation and Cloud Computing. Based on scenarios in the healthcare sector the benefits and challenges of such transfer are presented.
In this report we present an architectural approach to add quality-of-service (QoS) assurance and location awareness to service-based systems within existing clinical infrastructures. To address typical design requirements of such systems (e.g., cooperating services, performance and availability) the work proposes a service-oriented architecture (SOA) as architectural concept and architectural translucency to provide stable QoS. We evaluate position sensing systems, QoS assurance approaches and present design principles for service-based health care applications. Furthermore, we present a clinical application scenario and an architectural approach to integrate existing infrastructure into a human centric assistance system.
Cloud computing, especially Software-as-a-Service (SaaS), changes the IT processes of companies for application deployment, access, usage, maintenance, governance and management. In an age of Bring-Your-Own-Device, small businesses through to globally operating companies increasingly support their employees and customers with SaaS-applications that allow access to internal and external business information. Whether employees are in the office, at a client facility, at home or on the road, they need fast, easy access to business applications with any type of device.
SaaS offers companies an interesting alternative to classical on-premise IT solutions. Cloud computing provides innovative applications, high connectivity and performance, cost reduction, flexibility and fast time to market with a minimum of effort. Cloud computing is a special form of outsourcing that has its roots in the fifties. Ten years ago similar concepts to cloud computing e.g. Application Service Providing (ASP) appeared and failed. But it seems that the willingness to use cloud computing is now much higher and the cost pressure effects of the financial crisis also motivate decision makers in companies to focus on cloud computing.
This contribution presents the results of actual scientific literature investigations alongside interviews with owners of Software-as-a-Service Marketplaces. It describes several types of SaaS marketplaces using different business models to bring together customers and providers. It shows that SaaS marketplaces are two-sided and demonstrates how platforms are emerging that bundle features into significant value propositions for both sides.
This work is relevant to firms who seek business solution recommendations beyond the focus of their on-premise-focussed advisors. It is also relevant for owners and potential owners of SaaS marketplaces and SaaS providers exploring alternatives in their distribution mix.
We present MagicMap, a cooperative, hybrid positioning system developed at the Humboldt-University in Berlin. While most other positioning systems are limited to specific scenarios and technologies our system provides means to incorporate any available wireless networking technology. Currently, MagicMap supports WLAN, RFID, and ZigBee as wireless technologies for positioning and Linux, Windows, and Windows CE as platforms. Position calculation and exchange is based on a cooperative approach allowing an open internet community to share the required data.
Cloud-Computing, insbesondere „Software as a Service (SaaS)“ und „Platform as a Service (PaaS)“ ist zugleich Herausforderung und Chance für IT-Anwender. Marktplatz-Ansätze aus der Welt der mobilen Applikationen (App Stores) können eine Grundlage für die Vermarktung von Software-Diensten darstellen. Ihre Konzepte lassen sich jedoch nur durch eine erweiterte Betrachtung von funktionalen und nicht-funktionalen Aspekten der webbasierten Dienste in die Welt des Cloud Computing übertragen.
Application Stores und Marktplätze für webbasierte Dienste (z.B. Asperado, Cloud-Portal, Software-Marktplatz) helfen bei Identifizierung und Bewertung der Angebote und bei der Kommunikation mit potentiellen Kunden.
What processes must have taken place so that HR managers or operations managers somehow ‘know’ that they have to do things differently from the way they did things five or fifteen years ago? How do they learn what the latest management trends are? The creation and diffusion of management theories and practice is generally viewed as a three stage process: business schools and consulting firms produce the knowledge, the business press disseminates it, and then there is a process of legitimization as these theories become part of ‘common sense’ and form the standard managerial discourse through their representation in non-business media. An ever increasing amount of attention has been paid to the first two of these stages, but relatively little has been paid to how management knowledge might be diffused through other methods. This paper is an attempt to address this gap.
This paper determines the relevance of industrial property rights to the development of innovations in the fashion industry. It examines how the level of innovation can remain high despite a free exchange of intellectual property – fashion designs – within the industry:
The importance of innovation for a fashion business in the industry is determined by the choice of it’s competitive strategy. That is, either to be an innovator who creates fashion innovations or to be an imitator who adopts them once they have proven their ability to prevail in the market. The success of innovators depends largely on their ability to react to fashion trends, reinforced by the social role
of fashion products and to the extent of their potential to confer status on the owner. Thus the duration of a temporary monopoly gained by an innovation is limited not only by the market entrance of imitators – a period of time that
can be prolonged by making use of industrial property rights protection – but also by the constant changes in fashion, a process barely affected by the utilization
of intellectual property rights protection. A monopoly maintained by using intellectual property rights might very well not extend the product life cycle beyond the limits posed by the shifting changes of fashion; moreover, an extended life cycle maintained in these circumstances could seriously limit the innovators agility in satisfying consumer demand in line with fashion trends and provoke an inappropriate allocation of resources to developing unfashionable innovations, resulting in a much greater risk of product failure.
Many companies use business process modeling to support various improvements initiatives leading to an increasing number of process models. Typically, these models are stored in a collection containing several hundreds of process models. In many cases, process models are overlapping, although parts could be easily reused saving costs and efforts. Different labeling styles and evolving process models complicate the detec- tion of reusable model parts. In this paper, we propose a novel approach for the detection of equivalent and similar process model parts that ex- ploits semantic comparison of activity labels and behavioral comparison of control flow. We evaluate our approach on the SAP Reference Model, a collection with 604 process models. The evaluation reveals insights for the thresholds of semantic and behavioral similarity of process models as well as their influence for similar process part detection. Hence, we identify five candidate groups with specific similarity properties that contain reoccurring process parts.
