Students who started their bachelor degree course in the ISE program as from winter semester 2008/2009 must take a compulsory practical project, for which 6 ECTS-Credits are attributed.

Within this practical project, a group of students receive a well-defined technical task. This task should be solved in a team under supervision and should be handled like an industrial project including specification, conception, interface co-ordination, scheduling, scientific literature research and the presentation of the results.

The practical project aims at providing practically-oriented, basic skills as well as an environment for acquiring experience in work-sharing and autonomous handling in a social context. Besides a technical deepening, which can be seen as a preparation for the later bachelor thesis, the students should also acquire through this, soft skills in the following fields: ability to work in a team, ability to communicate (agreements in team, presentation), self-learning aptitudes (literature research, self-organized work) and the use of project management methods.

The practical project is done in parallel to the lectures during the lecture period.

The practical project must be done in a team, meaning involving at least two students. Depending on the task to be solved, the size of the group can be respectively adjusted.

Through appropriate supervision, the students should be urged to achieve the soft skills listed in their corresponding examination regulation. For that, attending team-meetings and seminars, in which intermediate and final results should be presented is compulsory. This must be followed by a final documentation.

The targeted 6 ECTS-Credits mean a complete workload of 180 working hours for each student. Here, the time allocated to preparation, literature research, team meetings, seminars, documentation etc. should be taken in account. These working hours can be spent, depending on the task, outside the supervising department. Nevertheless, meetings and seminar’s attendance is mandatory.

At the end of the project, each project participant receives an individual grade following the usual marking schemata.

No registration at the examination office is necessary. The project is directly surveyed by the supervising department. The grades will later be sent to the examination office, provided the project has been evaluated as successful.

The corresponding project documentation will uniquely be submitted at the department and not at the examination office. The form, content and size of the documentation should be agreed with the project supervisor. It is possible to submit a common documentation and not a single documentation per student, but it should be stated, which student was responsible for which chapter.

Project Work Offers for Mechanical Engineering in Winter Semester 2011/12

 

Title

Integration of a melt pump into a natural gas-powered plastification system and validation of the process influences

Description

At the Institute of Engineering and Plastics Machinery at the University of Duisburg-Essen, an alternative method to the plasticization of polymers was developed. Today, the polymer melt required to produce plastic products like plastic films or injection molding parts is provided through an extruder. The dissipative energy to plasticize it is implemented through the drive and the extruder screw. The alternative system uses an almost shear-free method for plasticizing. The polymer is melted via direct heat conduction. The necessary heat energy comes from burning natural gas in a natural gas-based heater.

To build up the required pressure for the forming of the melt flow a melt pump has to be integrated into the concept. The prototype at the laboratory of the Institute of Engineering and Plastics Machinery of the concept is already designed for the integration of a melt pump, the pump itself is available at the department. The main fokus in this work is to connect the pump to the system controller, the plasticizing process and an illustration of the process-specific influences. Important key facts are the potential throughput of the plant and melt quality.

Title

Zinc air batteries as option for storage of renewable electricity

Description

As future power source for electric vehicles, metal air batteries are discussed. As well lithium air as zinc air batteries are topics in current R&D. Primary, non-rechargeable zinc air batteries are commercially available, but the realisation of secondary, rechargeable batteries is still a challenge. The system is interesting due to relatively low cost of zinc. In addition to typical electrical charging processes, mechanical recharge is possible, if zinc slurry is used as active mass for the battery. The discharged zinc oxide slurry could be regenerated at central facility using renewable energy.

In the scope of the ISE project work the following tasks should be addressed:

  • Literature overview of recent progress in rechargeable zinc air batteries
  • Material selection for zinc air batteries: electrodes, electrolytes, diaphragm
  • Construction of a zinc air battery with a CAD program
  • Component selection for a zinc air battery system
  • Design of a zinc air battery test rig

Title Technical solutions for automated biopsy procedures of the female breast under MRI
Description In Germany, breast cancer is the most common type of newly diagnosed cancer in women. Statistically, there is a 5-year relative survival rate for these patients of around 85%. The chances of a cure are directly dependent on the time and the quality of detection and thus on the quality of the diagnostic process.
To secure the diagnosis by means of carrying out a histopathological classification, it is necessary to take an appropriate tissue sample. In dependence on the type of lesion, this biopsy is carried out in a magnetic resonance imaging due to the high level of detail produced in the imaging of the soft tissue. To ensure a defined tissue removal, it is necessary to have a reliable fixation and compression of the breast and a guidance of the biopsy needle adapted to the demanded position.
These challenges will partially be taken up by the members of the project work team. Under full consideration of the state of the art, possible new concepts of the fixation and compression module should be conceptual developed. Therefore the compatibility with the corresponding, actually existing other system modules of the automated biopsy system and the MR compatibility has to be secured. The best suitable concept has finally to be selected and presented as a specified concept.

Title Development of Logistic Regression Tool using C#
Description Mit der linearen Regressionsanalyse können die Einflüsse auf diskrete Variablen nicht untersucht werden, da wesentliche Anwendungsvoraussetzungen, wie Normalverteilung der Residuen und Homoskedastizität, nicht gegeben sind. Ein lineares Regressionsmo-dell kann bei solchen Variablen zu unzulässigen Vorhersagen führen.
Analog zur Regressionsanalyse werden bei der logistischen Regression mit Hilfe eines Regressionsansatzes Gewichte bestimmt, mit denen die unabhängigen Variablen die Wahrscheinlichkeit des Auftretens eines Ereignisses, der abhängigen Variablen, beein-flussen. Anders als bei der klassischen Regressionsanalyse ist die Zielgröße nicht met-risch skaliert, sondern kategorial mit nominalem Skalenniveau.
In diesem Projekt soll das Verfahren der Logistischen Regression soll als benutzer-freundliche GUI in C# implementiert werden.

Title WELDING FIXTURE DESIGN
Description

During the manufacturing process of compressor components, different types of manufacturing techniques are applied. One of these techniques is the manual welding of rotor components with rod electrodes. Therefore, the weld assembly components rotor disc and covering disc must be fixed during the welding process (Fig 1). Figure one shows how this problem currently is solved. But this approach is not satisfying. Hence, a suitably solution for a fixture of this components should be developed in this project work.

The solution has to be developed and documented with the use of all necessary and available tools. A comprehensive paper with all necessary documents, such as drawings or calculations, is expected. More detailed information will be provided in time.

Title Study of the Adsorptive Removal of Water from Air
Description In der chemischen Industrie ist es häufig nötig Wasser aus Gasen oder Luft zu entfernen, bevor weiterverarbeitende Prozessschritte stattfinden können. Wasser kann zu Katalysatorvergiftungen, geringeren Reaktionsausbeuten, beschleunigter Korrosion oder Verstopfung der Leitungen durch Eis und Hydrate führen. Ein Verfahren, das sich besonders für die Erreichung sehr geringer Wassergehalte (<< 20 ppm) eignet, ist die Adsorption.
Ziel der Arbeit ist es, eine Literaturrecherche durchzuführen, an einer vorhandenen Versuchsanlage verschiedene Adsorbentien zu testen, Adsorptionsisothermen aufzunehmen und diese an entsprechende Isothermengleichungen anzupassen. Darauf aufbauend soll dann ein Adsorber für den industriellen Maßstab ausgelegt werden.

Title

Mounting a SICK Laser Sensor on a rotating platform and operating the apparatus

Description

The SICK Laser shown above is used for measuring distances of objects. However since the laser is only able to scan in one line, information related to the size and shape of the object is not available.

The task is to mount the sensor on a rotating disc with constant rpm, and to extend the image processing to three dimensions. An apparatus to mount and hold the sensor is to be realised. The drive system should be kept cost efficient and small.

The work could be structured as follows:

  • Evaluation of a drive system for the rotating disc
  • Suitable mounting apparatus (removable)
  • Calibration of the sensor

Title

Development of an innovative concept for a transportable partial-autarkic power generation unit from renewable energies

Description

For decentralized applications renewable energies offer great advantages, like no need of fuel and fuel transportation. Furthermore not every household on the world is connected to a power distribution grid. But beyond this huge market there is a second important application area for such devices. Natural or human caused disasters can occur to a breakdown of the power grid. In those cases emergency power supply units were used. Those units have a high demand of fossil fuel. But in case of disasters fuel is rather short. For that reason it would be very interesting to offer transportable partial-autarkic power generation units.

Within the frame of this project the team shall develop a concept for a transportable partial-autarkic power generation unit in scale of ISO-Containers, which only uses renewable energies like e.g. sun and wind. At first a literature study has to be carried out. Based on this a concept has to be developed and predesigned. Therefore every team member has to take a part-task. Part-Tasks could be for example: PV cells, wind turbine, back-up technology and computer-aided design of the overall concept. During the processing period continuous meetings will be hold to ensure the project progress. Finally, the concepts as well as the results will be presented in a written report and a project presentation.

For each sub-task following steps have to be done:

  • Literature study and compilation of the state of the art
  • Development of concept(s)
  • Feasibility study
  • Thermodynamic assessment
  • Economic evaluation

Title

Planung, Bau und Inbetriebnahme einer Aktivkohlefilteranlage im Labormaßstab sowie anschließende Bewertung verschiedener Aktivkohlen hinsichtlich der Entfernung eines ausgewählten organischen Störstoffes

Description

Die Studierenden werden die Filteranlage planen, skizzieren und, nach Beschaffung der erforderlichen Bauteile durch den Lehrstuhl, eigenständig bauen. Dabei müssen Einzelteile verschraubt und teilweise geklebt werden sowie die Elektronik für die Messdatenerfassung installiert werden. Im Anschluss daran werden die Aktivkohlefilter mit Unterstützung seitens des Betreuers in Betrieb genommen. Dabei werden zunächst Berechnungen hinsichtlich der erforderlichen Aktivkohleschütthöhe sowie der  Filtrationsgeschwindigkeit vorgenommen. Nach Einspülen des Filtermaterials und Behebung eventueller Probleme beim Betrieb der Filter, können dann organische Störstoffe dosiert werden. Die über mehrere Wochen stattfindende regelmäßige Probennahme und anschließende Bestimmung der Konzentration im Ablauf der Filter (zeitliche Organisation wird durch die Studierenden übernommen) liefert letztendlich nach Auswertung aller Ergebnisse eine komplette Durchbruchskurve, anhand derer die Qualität der untersuchten Aktivkohlen bewertet werden kann. Die Vorgehensweise stellt ein in der Praxis der Wasseraufbereitung gängiges Verfahren zur Beurteilung verschiedener Aktivkohlen hinsichtlich ihrer Adsorptionskapazität dar. Auch die Beurteilung eines neuen Störstoffes, hinsichtlich seiner Neigung zur Adsorption an Aktivkohle und die damit einhergehende Prüfung der Eignung einer Adsorptionsstufe zur Entfernung dieses neuen Störstoffes, ist ein mögliches Anwendungsgebiet dieser Testfilter.
