In order to interact with its mobile clients in an ubiquitous and smart fashion, a “mobility-supporting infrastructure” has to use context information about its own and the user’s state. Based on context information, actions have to take place which services are offered to mobile clients. In this paper we discuss the various level of abstraction where context plays an important role for designi...

Current blockchain platforms, especially the recent permissioned systems, have architectural limitations: smart contracts run sequentially, all node executes all smart contracts, consensus protocols are hard-coded, the trust model is static and not flexible, and non-determinism in smart-contract execution poses serious problems. Overcoming these limitations is critical for improving both functi...

The Open Smart Grid Protocol (OSGP) is a widely used industry standard for exchanging sensitive data between devices inside of smart grids. For message confidentiality, OSGP implements a customised form of the RC4 stream cipher. In this work, we show how already known weaknesses of RC4 can be exploited to successfully attack the OSGP implementation as well. The attack modification is able to ef...

We propose a novel application of sBs in embedded optical fibers as a building block for the implementation of optical neural net based on smart structures. By employing well established technology in fiber embedding in structures, and exploiting the ability of sBs as a highly versatile ambient sensor, and its nonlinear optical property of energy addition and subtraction to perform optical arit...

Technology innovation has become one of the driving forces that advance tourism industry, but industry yet to account for manner in which personal technologies can foster tourists’ sustainable well-being. Generating promotes well-being individuals is deemed be challenging because experience needs users’ psychological and their attitudes towards technology. A holistic apprehension these needs, r...

This paper illustrates main research activities and results of the project “TETRis – TETRA Innovative Open Source Services” concerned with enabling innovative services for Smart City/Smart Territory by means of technological tools and intelligent platforms for collecting, representing, managing and exploiting data and information gathered from sensors and devices deployed in the territory. Tech...

Smart beta products are a disruptive financial innovation with the potential to significantly affect the business of traditional active management. They provide an important component of active management via simple, transparent, rules-based portfolios delivered at lower fees. They clarify that what investors need from their active managers is pure alpha—returns beyond those from static exposur...

This paper presents a novel method of employing "smart objects" for problem solving in virtual environments. Smart objects were primarily used for behavioral animation in the past. The paper demonstrates how to use them for AI and planning purposes as well. We formally define which operations can be performed on a smart object in terms of their requirements and their effects. A planner uses thi...

Driven by the development of smart buildings and smart grids, numerous of research has focused on developing optimal operation strategies for smart buildings with the aims of reducing energy consumption and cost, as well as improving the grid reliability. Unfortunately, most of the studies from smart building perspective only target on a single building with elaborated energy forecasting models...

The last years have seen an unprecedented amount of attacks. Intrusions on IT-Systems are rising constantly both from a quantitative as well as a qualitative point of view. Recent examples like the hack of the Sony Playstation Network or the compromise of RSA are just some examples of high-quality attack vectors. Since these Smart Attacks are specifically designed to permeate state of the art t...
