text: "Ressourcenverbrauch, CO2-Fußabdruck und Abfallaufkommen sind zentrale Themen
bei der nachhaltigen Entwicklung der Bauwirtschaft. Besonders mit einem Gebäudeabbruch
geht ein enormer Ressourcen- und Energieverlust einher. Diese Arbeit fokussiert
den Abbruchprozess am Beispiel einer öffentlichen Verwaltung und analysiert die
Möglichkeiten dieser, Kreisläufe von Bauteilen und -materialien in der lokalen
Bauwirtschaft zu fördern. \r\nZunächst wurde der IST-Prozess für einen Abbruch
von Gebäuden am Beispiel des Kreis Lippe aufgenommen und Schwachstellen für die
Wiedereinbringung von Bauteilen und -materialien identifiziert. Danach wurden
Best Practice Ansätze von öffentlichen Verwaltungen in Deutschland recherchiert
und anschließend dies um den europäischen Raum erweitert. Der letzte Teil der
Analyse bezieht sich auf das RE-BUILD-OWL Projekt, mit welchem der Kreis Lippe
plante eine Vorreiterrolle in zirkulärem Bauen einzunehmen, und wie die Projektergebnisse
die Wiedereinbringung von Bauteilen und -materialien im Rückbauprozess positiv
beeinflussen können. \r\nEs hat sich gezeigt, dass sich die Best Practice und
die Projektergebnisse positiv auf die Schwachstellen des Abbruchprozesses auswirken
können. Konkret wurden für den Kreis Lippe vier Handlungsempfehlungen formuliert.
1. Wissensaufbau: Zwar wurde deutlich, dass bei Einzelpersonen großes Fachwissen
beseht, ein Austausch zwischen den Mitarbeitenden bestand jedoch nicht ausreichend.
Außerdem besteht auch Bedarf an externen Schulungen geschult/ Sensibilisierung.
2. Digitalisierungsstrategie: Langfristig deutet sich im Bausektor ein Wandel
zur Nutzung von Building Information Modeling ab. Es wird empfohlen, diesen Wandel
im Kreis Lippe vorzubereiten, um die Mitarbeitenden in dem Wandel mitzunehmen
und diese Veränderung proaktiv anzugehen. 3. Aktive lokale Marktgestaltung: Der
lokale Markt lässt sich durch die Erhöhung der Nachfrage von verfügbaren Sekundärmaterialien
und der Erhöhung des Angebotes von verfügbaren Sekundärmaterialien beeinflussen.
Wenn zusätzlich innovative Technologien in der Region gefördert werden, lassen
sich langfristig Materialkreisläufe entwickeln. 4. Baustoff- und Materialdistribution:
Diese Handlungsempfehlung gilt als Teil der Erhöhung des Sekundärmaterialangebots.
Um die Angebotserhöhung der Sekundärbauteile und -materialien zu bewerkstelligen,
wurden zwei Optionen vorgeschlagen. Zum einen kann die Fremdleistung der Identifizierung
und Distribution eingekauft werden, zum anderen ist eine interne Umsetzung mit
Aufbau einer Bauteil- und Materialbörse möglich. Wichtig ist in beiden Schritten,
dass vor einem Abbruch ein Audit des Gebäudes und eine Klassifizierung der Bauteile
und -materialien auf Wiederverwendbarkeit durchgeführt wird. Eine mögliche Umsetzung
der Veränderungen wurden in einer beispielhaften SOLL-Prozess-Darstellung skizziert.
\r\nDie Ergebnisse dieser Arbeit zeigen das Potenzial sowie konkrete Schritte
auf, die der Kreis Lippe hat, um Bauteile und -materialien in einem Kreislauf
zu behalten. Die Best Practice Analyse ist nicht spezifisch für den Kreis Lippe
durchgeführt worden, weshalb die Ergebnisse zusätzlich für einen allgemein übertragbaren
Erkenntnisgewinn zur Verfügung stehen. Auch andere öffentliche Verwaltungen können
anhand der Ergebnisse dieser Arbeit Handlungsschritte ableiten. "

text: "Resource consumption, carbon footprint and waste generation are key issues
in the sustainable development of the construction industry. Demolition of buildings
in particular is associated with an enormous loss of resources and energy. This
thesis deals with the role of public administrations, in particular with their
demolition process, and analyzes the possibilities of these to promote circular
economy of building components and materials in the local construction industry.\r\nFirst,
the actual process for demolishing buildings was recorded using the example of
the Kreis Lippe and weak points for the reuse of components and materials were
identified. This was followed by research into best practice in public administration
in Germany and then in Europe. Finally, the last part of the analysis refers to
RE-BUILD-OWL, a project with which the Kreis Lippe planned to take a pioneering
role in circular construction, and how the project results can positively influence
the reuse of components and materials in the deconstruction process.\r\nIt was
determined that best practice and the project results can have a positive impact
on the weak points. Specifically, four recommendations for action were formulated
for the Kreis Lippe. 1. building knowledge: Although it became clear that individuals
have a great deal of specialist knowledge, there was not enough exchange between
the employees. In addition, external training should be provided as well. 2. digitalization
strategy: In the long term, there are signs of a shift towards the use of Building
Information Modeling in the construction sector. This change should be prepared
in the Kreis Lippe in order to take employees along with the change and proactively
tackle this change. 3. active local market design: The local market can be influenced
by increasing the demand for available secondary materials and by increasing the
supply of available secondary materials. If innovative technologies are also promoted
in the region, material cycles can be developed in the long term. 4. construction
components and material distribution: This recommendation for action is part of
increasing the supply of secondary materials. There are two options for increasing
the supply of secondary components and materials. On the one hand, the external
service of identification and distribution can be purchased; on the other hand,
internal implementation with the establishment of a component and material exchange
is possible. In both cases, it is important that an audit of the building and
a classification of the components and materials for reusability is carried out
before demolition. A possible implementation of the changes was outlined in an
exemplary target process diagram.\r\nThe results of this work show the potential
and concrete steps that the Kreis Lippe has, to keep components and materials
in a cycle. The best practice analysis was not carried out specifically for the
Kreis Lippe, which is why the results are also available for a generally transferable
gain in knowledge. Other public administrations can also derive action steps from
the results of this work."

text: The development of autonomous vehicles and the integration of new information
and communication technologies are making the reliability of electrical systems
and components in modern vehicles increasingly important. Electrical connectors
are a crucial component in an electrical on-board system. They are exposed to
a wide variety of influences by the environment and operating conditions. Thus,
the degradation of electrical connectors can occur. Material and surface analysis
methods are the tools used to analyze the degradation mechanisms in connectors
after lifetime tests, as well as in field operations. Within the framework of
this study, a wide variety of methods from the analytical scope are presented
and discussed. The connector surfaces degraded by different failure mechanisms
are analyzed using various material and surface analysis methods. The quality
and the nature of the analyses results obtained from various analysis methods
are compared. Also, this study deals with the benefits and limitations, as well
as the effort and the specific challenges of different material and surface analytical
methods for the evaluation of failure mechanisms from the point of view of a material
and surface analyst.

text: "Material flows and energy flows can be correlated with sufficient data, e.g.
on production energies, annual production quantities and degrees of dissipation
with temperature increases in the atmosphere, volumes of molten ice or sea level
increases, as well as with probability statements, information densities and management
recommendations. All these quantities can be described by the comprehensive term
entropy.\r\nIn order to consider the efficiency of material and energy flows,
the difficulty to understand the concept of entropy with its different definitions
can be summarized simply and easily in a model related to ice cubes.\r\nThe quality
of a model containing percentage probability statements, statements on dissipation
in material flow models in connection with statements on information density and
its description by the ice cube model is still to be determined in practice in
suitable material flow models. Such projects should show the types of mathematical
correlations between dissipation degrees, entropy increase, increase of molten
ice and sea level rise.\r\n"

text: Selective laser melting is a powder bed fusion technology that uses a laser
as an energy source in order to directly build fullydensemetal parts. Optimal
fabrication requires a comprehensiveunderstanding of the main processing,as it
affectsthe part quality. Wherefore, the objective of this paper is to perform
a survey, data checking and collecting ofprovided parameters to compare and contextualize
it versus the respective values used in the processby the research studies. The
work is focused on cobalt-chromium alloys (CoCr) which are widely used in dental
and medical applications. This work focusesonsurfacequality and hardness as built
and after the post-processes. As well, the approaches in bond strength after post-processing
are considered, comparing the results made by different manufacturing techniques.
Finally, this work compares results acquired in surface roughness asbuilt, and
tensile strength of parts made by selective laser melting versus the traditional
technique cast, before and after heat treatment.

text: Under the circumstance of advanced globalization, it is increasingly difficult
for production companies to remain competitiveness. Many of them are forced to
restrict budget and reduce production costs. In addition, the customization of
product increases continuously. This results in extension of product variation
and reduction of product life cycle. Therefore, the companies need a high flexibility
to respond quickly to changes in the market and to customer requirements. Lean
thinking, as a powerful tool, has been implemented by many companies in production
and manufacturing. In order to avoid waste in lean manufacturing, it is necessary
to manage efficiently the material flow. In this study, for a lean material handling
system in the lean manufacturing of a company, an in-plant milk-run distribution
system is taken into consideration. The system consistsof vehicles, which move
periodically in certain routes. The materials are delivered in short intervals
from a central storage area to several points of use in the production. By using
milk-run in plant, the material handling processes can be standardized and therefore
the waste can be eliminated. One additional aim of the study with milk-run distribution
for the material provision is to minimize the handling time, which determines
directly the personal costs. In order to realize the aim, the work has beendivided
into several steps. At first, the production processes, especially the material
provision for the production have been analyzed. Secondly, the technological solutions
have been analyzed in order to handle different loading units required by different
machines in the production. Thirdly, the milk-run distribution for lean production
is formulated as an optimization problem with the object of minimizing the number
of vehicles and the distance traveled under the constraints of specific time periods,
capacity of vehicle and related stations etc. Fourthly, two optimization methods
are developed in order to find the optimal solution for the milk-run problem and
the performance of different methods is also compared.
