Bank and trust – two words but one meaning in customers’ minds. When interacting with financial service providers, customers are consistently looking for “trust signals” that comfort their decisions and “distrust signals” which create doubt. Therefore, service providers need a deep understanding of the customers’ requirements and wishes. To identify trust and distrust signals, we combine established user experience research methods with a new testing procedure to gain helpful recommendations for optimizing the online appearance of banks. The contribution is divided into three parts: Firstly, we investigate current approaches in the financial service industry. Secondly, we provide a corpus describing the relationship between the customers’ perception of a bank’s website and trust. Thirdly, an empirical study based on qualitative user experience testing with banking website customers shows the value gained by optimizing the banks’ virtual interface by enhancing “trust signals” and avoiding “distrust signals”.
Techno-economic comparison of membrane distillation and MVC in a zero liquid discharge application
(2018)
Membrane distillation (MD) is a thermally driven membrane process for the separation of vapour from a liquid stream through a hydrophobic, microporous membrane. However, a commercial breakthrough on a large scale has not been achieved so far. Specific developments on MD technology are required to adapt the technology for applications in which its properties can potentially outshine state of the art technologies such as standard evaporation. In order to drive these developments in a focused manner, firstly it must be shown that MD can be economically attractive in comparison to state of the art systems. Thus, this work presents a technological design and economic analysis for AGMD and v-AGMD for application in a zero liquid discharge (ZLD) process chain and compares it to the costs of mechanical vapour compression (MVC) for the same application. The results show that MD can potentially be ~40% more cost effective than MVC for a system capacity of 100 m3/day feed water, and up to ~75% more cost effective if the MD is driven with free waste heat.
In this paper we report on the commercial background as well as resulting high-level architecture and design of a cloud-based system for cryptographic software protection and licensing. This is based on the experiences and insights gained in the context of a real-world commercial R&D project at Wibu-Systems AG, a company that specialises in software encryption and licensing solutions.

An energy oriented design concept was developed within the research project PHOTOPUR which has the development of a PV powered water cleaning system as main focus. During a wine season Plant Protection Products (PPP) are several times sprayed on plants to protect them of undesired insects and herbs or avoid hazardous fungus
types. A work package of the project partner INES in Offenburg led to a design introducing energy profiling already in the early beginning of a product design. The concept is based on three pillars respecting first the
requirements of the core process making up filtering and cleaning and secondary aspects which run, support, maintain and monitor the system to secure availability and product reliability.
The presented paper shows that the results of the design tools guided the developers to assemble a functional model of the water decontamination unit which was manually tested with its concatenated steps of the water cleaning process.
