M-Computing for Real-Time Negotiation Support.

Mobile computing (or m-computing) technologies have recently made sufficient progress making it possible to seamlessly integrate communications and data processing in m-commerce applications. Using telemedicine as an illustration of m-commerce, we propose a system analysis and design method to formulate communications, knowledge management and transaction processing requirements for each of the business processes in a mobile application workflow. We also discuss various technological supports to implement these requirements. We advocate the use and design of processoriented software agents to support a highly distributed and loosely-coupled federation of wireless and legacy information systems to support decision, bargaining and negotiation in a real-time environment

Optical coherence tomography in interventional cardiology—Research field or future daily routine?

AbstractNowadays, optical coherent tomography (OCT) as the most precise morphologic technique is used in the increasing number of cases, both in routine clinical situations and research projects. Huang and co-workers reported the first clinical use of the 2-dimensional OCT in 1991, suggesting the principle of its use both in ophthalmology and interventional cardiology. The method has developed rapidly since that time. Interventional cardiologists benefit from its detailed intravascular imaging ability, providing real-time information of the intracoronary pathology. Researchers acknowledge the resolution, allowing detailed analysis of vessel structure. Its axial resolution level is approximately 10–15μm, which is far from any other method used in interventional cardiology. The review will address the principle of the method and the main fields of the relatively short history of the OCT use as a routine clinical imaging method. We will summarize the main OCT milestones in the research field and its possible future as well. The review will describe OCT as the method under rapid development that should be considered as a new “gold” or even “platinum” standard for the coronary vessels imaging

Digital transformation of business ecosystems: Evidence from the Korean pop industry

The notion of business ecosystems is gaining prominence among academics and practitioners. Scholars advise that business ecosystems are inherently fluid, unbounded and amorphous and thus that their boundaries can shift. Practitioners further suggest that business ecosystems are characterised by inter-network - as opposed to inter-firm - competition, and, moreover, that they are mainly driven by technological advancements. And yet few studies examine the role of information technology (IT) in driving boundary practices that enable the formation and transformation of business ecosystems. Through an in-depth case study of technology-enabled transformations within the Korean pop music (K-pop) industry, our study examines how the digital transformation of business ecosystems unfolded. Our study contributes to the emergent body of knowledge on business ecosystems in a number of ways. Our investigations uncover the conditions under which the constituent firms operate and analyse the role of IT and its implications on new organisational forms. From our analysis, we present a framework that reveals insights on critical boundary practices and formative strategies for digital business ecosystems. We illustrate how these boundary practices drive industry change, from a largely linear content delivery system resembling a value chain to a new value network of co-specialisation and self-organisation among firms in a new digital business ecosystem.N

Investigation of Circular Cylinder Flow in Water Using Temperature-Sensitive Paint

In the present investigation the method of Temperature-Sensitive Paint (TSP) is applied to visualize the unsteady pattern of surface flow on an immersed body in water. A ‘waterTSP’ has been developed with high temperature sensitivity in the range 10 °C < T < 40 °C. Experiments were conducted in a recirculating water tunnel where a circular cylinder was used as the test body. The range of the Reynolds number investigated is 3500 < Re < 14500. It is demonstrated that waterTSP is capable of showing unsteady heat flux on the model surface under flow conditions. For example, the footprint and the motion of the separation line can be identified. The dimensionless frequency of vortex shedding (Strouhal number, Sr) is measured from waterTSP images and the dynamics of turbulent near-wall structures are visualized
