Completed projects of the Institute of Smart Systems and Services

Here you can find an overview of the completed projects of the Institute of Smart Systems and Services:

Image evaluation - Development of a mobile measurement device (Funder: BMWi, Funding line: ZIM, Project lead: Prof. Dr. Greiner)

EmFaSe (Funder: BMBF, Project lead: Prof. Dr. Friedemann Mohr):
The central topic of the research project EmFaSe is the interaction of embedded ( "embedded") optical fibers with their surroundings, primarily regarding their application for sensor purposes. Such fibers are used, for example, as strain gauges, which are glued analogously to conventional electrical forms on the surface of a component to measure its deformation. In other applications, they are poured into materials whose volume change has to be determined. Examples are plastic fiber composites with integrated deformation sensors or materials of construction. The project will result in two benefits: the focus is initially on a better understanding of specific mechanisms which influence the behavior of the fiber and produce noise which distorts a strongly desired other measure. This effect should be suppressed at best by an optimized design of bedding materials, a particularly important aspect of fiber gyroscope, a sensor for aircraft technology. On the other hand, by a better understanding of cause-effect relationships exactly the opposite, namely stronger interaction between the fiber and the surrounding area can be used: a desired effect when it comes to the use of fibers as strain gauges.

FOSBA - Fiber optic sensors for structural monitoring (Funder: BMBF, FHprofUnt, Project lead: Prof. Dr. Friedemann Mohr):
The aim was to develop the usage of fiber optic sensors for structural health monitoring. Here sensors of the type FBG (Fiber Optic Bragg Gratings) represent the focus of attention. One of the starting points for the work was the presence of previous project experience of the working group with embedded fiber sensors - there, however, the fiber gyroscope - in which just the interaction between the fiber and its surroundings are at the center of interest. While we went there to get a better understanding of the physics to suppress this interaction in the best possible way, we then had to deal with the reverse situation, namely the maximization of this interaction. Besides the description of the interaction the question of the reading of the effects occurring in the FBG sensor elements plays a second major role. Here, two different approaches were studied and the approach that was most appropriate for the task was implemented: White light irradiation and spectral analysis of the reflected light and scanning the grating spectrum by tunable external cavity lasers. For the problem regarding the separation of temperature and elastic effects in the fiber, we had to work with highly birefringent bragg grating fiber. There are no commercially available fibers; therefore, we tried to develop a university source for it with the help of a university partner. An essential advantage of FBG sensors, their ability to multiplex, i.e. to query in a single measurement range of series-connected sensor elements, was implemented by applying code division multiplexing method. The concepts should be used in collaboration with the commercial and academic partners on real building projects and evaluated in comparison with commercial measurement methods.

Ma-x-RM (Funder: MFG-Stiftung, Funding line: Karl-Steinbuch-Förderprogramm, Project lead: Prof. Dr. Bulander, Prof. Dr. Greiner):
The research project Ma-x-RM combines the topics of the Internet of Things and Internet of Services in the management concept "Anything Relationship Management" (xRM). Here xRM represents a significant expansion of Customer Relationship Management (CRM), in which any kind of entities (individuals, companies, but also smart things and objects) instead of the customer (Customer) are networked together and interact with each other and can collaborate. After an analysis of the state of the art as well as the delineation and evaluation of relevant usage scenarios, the project continues with its own development at two levels:
- A generic xRM concept is developed for the field of management and organization as an overarching open layer which allows an n: n interaction and -collaboration between all entities and IT systems of the various applications.
- Technically, a prototype is developed and evaluated for a selected application in the project. This is based on a usage scenario which was previously rated as relevant.
The project concludes with recommendations for a sustainable Anything Relationship Management in the form of a guideline.

MERSES (ZAFH, Land Baden-Württemberg, EU - EFRE, Project lead: Prof. Dr. Greiner):
The center MERSES represents a completely externally funded project of the Institute for Applied Research at Pforzheim University. Its main current research focus is on "embedded systems". The term embedded systems generally refers to computer systems which in turn are integrated into larger systems. They are an indispensable part of our modern, technological world and take over, largely invisibly, a variety of control and monitoring functions for the user. They are used in washing machines as well as for example, in mobile phones or GPS devices, motor vehicles, or cardiac pacemakers. The project is funded by the European Union, European Regional Development Fund and the state of Baden Württemberg, the Ministry of Science, Research and Art.

MID-Wave (Funder: Baden-Württemberg Stiftung, project lead: Prof. Dr. Greiner):
The detection and modeling of three-dimensional objects by means of digital image processing is rapidly gaining in importance. The task of a computerized quality inspection is to detect deviations from the norm and to classify the error. Reflective surfaces could not be explored by simple direct quality control. By means of deflectometry surface defects can be detected, an automatic assignment to error classes, however, has been barely possible so far. Within the project MID-Wave (Multiscale inspection by deflectometry and wavelet-based method) new solutions have been researched and developed in order to allow better classification.

SECURITAS - Security management in communication networks (Funder: BMBF):
In this project, a junior research group dealt with selected security issues in communication networks (email, VoIP) and the development of new application-oriented concepts of security management for network services specifically for small and medium-sized enterprises (SMEs) in cooperation with a Pforzheimer SME. Innovative approaches to identify SPAM and SPIT and to deal with spam emails or SPIT phone calls had to be discovered, developed and evaluated.

Usability of company-based product-service-systems in medium-sized businesses (Use PSS) (funder: BMWi, funding line: Mittelstand-Digital, project lead: Prof. Dr. Bulander und Prof. Dr. Kölmel):
The role of manufacturing companies is changing fundamentally: While the focus has until now been primarily on the development, production and distribution of high quality tangible products the customers expect complete solutions in the future. Product Service Systems (PSS) are appropriate for providing such a complete solution. They consist of a traditional product component which is complemented by services in the course of a product lifecycle. Ideally, both blend into one innovative total solution. In this context, using real use cases, the research project Use-PSS is developing and testing new business models that are specifically tailored to small and medium-sized businesses.
