WSDL Indexing and Packaging of Market, Materials and Car Related Web Services

Ausschreibung Abschlussarbeit

WSDL Indexing and Packaging of Market, Materials and Car Related Web Services“

Bachelorarbeit

Motivation:

Web services drive modern web and traditional applications by providing real-time access to data across multiple channels. In the automotive domain, the number of accessible web services is limited due to the proprietary nature of each vehicle and its components and the relationship to original manufacturers. While an assortment of web services would greatly benefit the automotive recycling and reuse community, the lack of services greatly limits potential.

In the Cascade Use research group, research is being done on which existing web services are appropriate for use and how new services can be developed as wrappers for different car recycling data sources. This proposed project investigates the requirements of indexing and packaging of web services in three levels, namely: automotive, component and material levels. Each level contains multiple heterogeneous data sources, which are wrapped in custom web services that must be appropriately tagged with metadata to support indexing and further reuse outside of the Cascade Use project.

The expectations of this project are that the requirements for indexing and packaging of web services be investigated and reported on and then later applied to the generated web services. Results and qualitative characteristics of the process of applying UDDI metadata to web services and then packaging and indexing them form the analysis of this study. Evaluation of performance criteria and UDDI discovery potential based on WSDL standards could form a useful additional aspect to the study.

Previous exposure to web services in SOA and cloud-based frameworks would be a definite advantage.

Aufgabenstellung:

Candidates should have a sound overview of software engineering and be acquainted with the usage or implementation of web services. An exposé of 2-3 pages should be prepared after discussion in the themes of the project. The bachelor thesis of this project may be written in either German or English.

Automation of Metadata Embedding and Collection of Material Literature for Electronic and Electrical Waste

Ausschreibung Abschlussarbeit

Automation of Metadata Embedding and Collection of Material Literature for Electronic and Electrical Waste“

Bachelorarbeit

Motivation:

Electrical and electronic waste makes up a large fraction of the waste streams generated by the public with limited amounts of pre-sorting, pre-treatments and processing applied. The EU has funded the “European network for innovative recovery strategies of rare earth and other critical metals from electrical and electronic waste” (ReCreew) Cost Action project with the goal of improving collection and processing opportunities.

The domain requires specific metadata to be embedded into literature sources when selecting relevant metals and elements to process. This raises the challenge of automation, given the assortment of laboratory analyses published in journals and conferences, as well as supplementary metadata to further classify these sources. This project outlines an automation strategy of collecting these sources from academic search engines and repositories and then collating them with relevant author metadata, which is done by many popular reference managers. An additional process for scanning the document for relevant terms is then required. The term lists for each metadata feature are standardized, but the process should require minimal Human intervention.

Aufgabenstellung:

Candidates should come from a computer science background or from a similar discipline with relevant programming knowledge. Candidates should familiarize themselves with the identified domain and gather an overview of the theme of the study. An exposé of 2-3 pages should be prepared after discussion with the relevant stakeholders in the Cascade Use research group. The exposé should further elaborate the research methods proposed and provide a concrete overview of the subject posed. The bachelor thesis of this project may be written in either German or English.

A Methodology for Material Reporting from Heterogeneous Online Sources and Documents

Ausschreibung Abschlussarbeit

A Methodology for Material Reporting from Heterogeneous Online Sources and Documents“

Master-/ Bachelorarbeit

Motivation:

Online reporting generally relies on uploaded report documents or formatted websites. In the domain of recycling, these reports are limited in volume, which raises other challenges. Many automated systems generally require the data contained in published reports, which is very difficult when the original or processed data is not available in the form of a data web service or standardized dataset.

This project entails the creation of a methodology for extracting and parsing reporting documents from various recycling related online sources, such as governmental websites, geological surveys, company recycling reports. This methodology should ideally support automation to encourage simple extraction from these reports with minimal Human intervention. The evaluation aspect of this study relies on performance and functional support for various reporting sources. The accuracy and efficiency of the methodology when applied to a large variety of heterogeneous online reports and documents should be measured and compared to existing methods described in literature.

To develop the project as a master thesis, online sources such as direct website contents could be included to further support automation. Parsing of website information requires different strategies than document accessing and parsing, which should be reflected in the developed methodology.

Aufgabenstellung:

Candidates should come from a computer science background or from a similar discipline with relevant programming knowledge. Candidates should familiarize themselves with the identified domain and gather an overview of the theme of the study. An exposé of 2-3 pages should be prepared after discussion with the relevant stakeholders in the Cascade Use research group. The exposé should further elaborate the research methods proposed and provide a concrete overview of the subject posed. The bachelor/master thesis of this project may be written in either German or English.

A Mobile Interface for a Car Composition and Environmental Impact Tool

Ausschreibung Abschlussarbeit

A Mobile Interface for a Car Composition and Environmental Impact Tool “

Master-/ Bachelorarbeit

Motivation:

The available assortment of compositional information software tools is almost non-existent. No applicable system exists in the car recycling domain. The Cascade Use research group has noted this lack as a potential means of stifling car recycling and reuse due to different stakeholders not having sufficient information. Stakeholders such as public and governmental users have limited information available what is inside their vehicles with regards to components and materials and are generally unaware of the large amounts of critical materials embedded in their car, which inhibits their recycling/reuse behavior. Recyclers and remanufacturers also have different perspectives with regards to the current market price and material contents of cars and components. The Cascade Use research group is thus developing an architecture for supporting information provisioning with regards to composition and environmental impact.

This project extends the framework from a web application to rather develop a mobile application which supports interactive queries about car/component compositions, environmental impact and relevant pricing information. The mobile application should contain a user-relevant interface appropriate to the selected mobile native platform, be compatible with the Cascade Use data and decision API, and support multiple locales for usage in countries outside of Germany.

Aufgabenstellung:

Candidates should come from a computer science background or from a similar discipline with relevant programming knowledge. Candidates should familiarize themselves with the identified domain and gather an overview of the theme of the study. An exposé of 2-3 pages should be prepared after discussion with the relevant stakeholders in the Cascade Use research group. The exposé should further elaborate the research methods proposed and provide a concrete overview of the subject posed.

Data Warehousing and Querying Protocol for Assembly and Material Information

Ausschreibung Abschlussarbeit

Data Warehousing and Querying Protocol for Assembly and Material Information“

Masterarbeit

Motivation:

In the domain of recycling, specifically for automotive recycling, there are very few current and relevant databases or systems which are available to the public. The Cascade Use research group is developing a large framework for aggregation of the different related data aspects of car recycling and reuse, which includes a relational database. A simple relational database does not offer as much flexibility and data drill-down/roll-up support as a data warehouse, so this would naturally be desirable for an EU-wide implementation of this architecture.

This project investigates the aggregation of various heterogeneous data sources wrapped as web services into a data warehouse which includes: a relevant schema to support the data provided, cached queries for common car related queries, relevant transformation, loading and cleaning operations and supplementary services. The project is developed using open source technologies, so the schema and implementation should be done with the same goals in mind.

Sample data can be generated for evaluation, or real-time data can be used, depending on the presence of each web service connected to the architecture. Evaluation through standard quality and efficiency metrics can be done to determine support and performance. Key conclusions and observations of the development process, together with any limitations encounters, should be scientifically presented with relevant motivations.

Aufgabenstellung:

Candidates should come from a computer science background or from a similar discipline with relevant programming knowledge. Candidates should familiarize themselves with the identified domain and gather an overview of the theme of the study. An exposé of 2-3 pages should be prepared after discussion with the relevant stakeholders in the Cascade Use research group. The exposé should further elaborate the research methods proposed and provide a concrete overview of the subject posed. The master thesis of this project may be written in either German or English.

Car Assembly Data Mining and Indexing

Ausschreibung Abschlussarbeit

Car Assembly Data Mining and Indexing “

Master-/ Bachelorarbeit

Motivation:

Original manufactures of cars and components typically do not share their composition and assembly information. Alternative data sources, such as laboratory analyses of components and assembly databases do exist, but with limited public exposure due to the data structure. This project outlines a process of mining and indexing these popular sources for clustering information about components, their compatibility and sourcing. By mining these databases, structural information about the assembly of a car can be obtained, which is directly relevant to the software architecture under development by the Cascade Use research group.

Analysis of the process, challenges and performance would form the pillars of the evaluation aspect of this project, followed by an indexing process of the data for future use by related researchers. Automation of the process would be the ideal case, but raises other issues of complexity and scope. This can be revisited after the basic requirements have been addressed. Deeper information can be mined by aggregating multiple data sources, which would be necessary to pursue this project as a master thesis project.

Aufgabenstellung:

Candidates should come from a computer science background or from a similar discipline with relevant programming knowledge. Candidates should familiarize themselves with the identified domain and gather an overview of the theme of the study. An exposé of 2-3 pages should be prepared after discussion with the relevant stakeholders in the Cascade Use research group. The exposé should further elaborate the research methods proposed and provide a concrete overview of the subject posed. The bachelor/master thesis of this project may be written in either German or English.
