text: We present a searchable encryption scheme for dynamic document collections
in a multi-user scenario. Our scheme features fine-grained access control to search
results, as well as access control to operations such as adding documents to the
document collection, or changing individual documents. The scheme features verifiability
of search results. Our scheme also satisfies the forward privacy notion crucial
for the security of dynamic searchable encryption schemes.

text: Surfaces covered with layers of ultrathin nanoantenna structures—so
called metasurfaces have recently been proven capable of completely controlling
phase of light. Metalenses have emerged from the advance in the development of
metasurfaces providing a new basis for recasting traditional lenses into thin,
planar optical components capable of focusing light. The lens made of arrays of
plasmonic gold nanorods were fabricated on a glass substrate by using electron
beam lithography. A 1064 nm laser was used to create a high intensity circularly
polarized light focal spot through metalens of focal length 800 µm, N.A. = 0.6
fabricated based on Pancharatnam-Berry phase principle. We demonstrated that optical
rotation of birefringent nematic liquid crystal droplets trapped in the laser
beam was possible through this metalens. The rotation of birefringent droplets
convinced that the optical trap possesses strong enough angular momentum of light
from radiation of each nanostructure acting like a local half waveplate and introducing
an orientation-dependent phase to light. Here, we show the success in creating
a miniaturized and robust metalens based optical tweezers system capable of rotating
liquid crystals droplets to imitate an optical motor for future lab-on-a-chip
applications.

text: Plastic freeforming (PF) is an additive-manufacturing process for producing
three-dimensional plastic parts based on 3D CAD data by applying plastic droplets
in layers. This process is used to produce customer-specific and complex geometries
(prototypes and small series) on organic sheets. A comparable serial process is
the injection of a second component onto organic sheets by injection molding.
A sufficient bond between the PF structure and the organic sheets is of particular
importance for each application. If this is not guaranteed, the composite system
cannot withstand the mechanical load and fails. The force exerted on the system
can no longer be transmitted between the PF structure and the organic sheet. The
organic sheet is made of glass fiber-reinforced polypropylene (PP). The connection
between the organic sheet and the PF structure is achieved by welding the molten
polymer droplets and the surface of the organic sheet. The PF structures are made
of PP to ensure sufficient compatibility with regard to the weldability of the
components. The processing of PP in the PF process is a challenge because PP is
a semicrystalline material. The shrinkage of semi-crystalline materials is significantly
higher compared to amorphous materials. Due to the layered structure of the components,
the shrinkage of the individual layers results in undesired warpage. The adhesive
strength between the organic sheet and the PF structure is investigated by determining
the bending strength in the 3-point bending test. The investigations include an
optimization of the process parameters to maximize the adhesive strength. The
experimental investigations show that an increase of the nozzle and build chamber
temperature leads to a higher adhesive strength. In further investigations, the
temperature of the nozzle shows no significant influence on the surface temperature
despite the expected heat radiation. The surface temperature is almost only dependent
on the temperature of the build chamber.

text: The mechanical properties of thin-walled plastic components are limited. One
approach to improve the strength or stiffness of these components is to reinforce
the thin-walled areas with an individually adapted Fused Deposition Modeling structure.
Fused Deposition Modeling (FDM) is one of the most commonly used additive manufacturing
processes. This process is characterized by the deposition of a fused, thermoplastic
filament. Depending on the form of the reinforcement structure, the resulting
hybrid structure should show higher strength or stiffness. The objective of the
project is to determine constructive design and process guidelines for FDM structures.
The FDM structure is to be used as a partial reinforcement for lightweight components
and be adapted to the respective load conditions. Because of the lightweight application,
the FDM structure should also have the lowest possible weight. The optimization
of the FDM parts for different load cases is realized by adapting the design parameters.
These parameters influence the layer generation and therefore also the inner structure
of the FDM parts. In preliminary studies, the manufacturing restrictions of the
FDM process are defined. The specimens are manufactured based on the Design of
Experiments. To determine the static strength properties, different tests (tensile,
compression, flexural, torsion and impact) are carried out. The investigations
show that the filling strategy affects the mechanical properties. As a result
of the investigations, design and process guidelines for the FDM structures are
established according to the load conditions.

text: Additive manufacturing processes, like the Fused Deposition Modeling (FDM)
process, do not need product-specific tools and create parts directly from the
CAD data. In the FDM process, the semi-finished product, a wire of a thermoplastic
polymer, is melted and forced through a nozzle. The continuous positioning of
this nozzle allows the polymer to weld together strand by strand and layer by
layer to produce a component. Because no mold is used in the FDM process, no holding
pressure can be generated as in injection molding processes, in which the holding
pressure is used to minimize the shrinkage and warpage of the part. In the FDM
process, the part is generated in an ambient pressure environment. Each strand
cools down and shrinks separately. This causes residual stresses in the part that
can lead to major warpage and a complete stoppage of the process. This is the
main reason why the material selection in the FDM process is restricted in comparison
to conventional polymer processing technologies. In this paper, the warpage of
different polymers is quantified as a criterion for evaluating the processability
of polymers in the FDM process. Due to the process principle, the part properties
in the FDM process are mainly influenced by the machine quality and the data processing,
so that it is difficult to test a material for FDM independently of the machine
and the data processing. Considering these influences, a custom-built specimen
is created to test and quantify the warpage of different types of blended and
reinforced polyamide 6. Considering the experimentally investigated warpage, the
materials can be evaluated and the warpage can be related to the shrinkage investigated
in pvT measurements. This procedure allows the machine- and process-independent
rating of the processability in terms of warpage for different materials. Alongside
other criteria, this is a necessary step to develop new materials with good processability
in the FDM process.

text: Das Fused Deposition Modeling (FDM) ist ein etabliertes additives Fertigungsverfahren
zur Her-stellung von thermoplastischen Kunststoffbauteilen. In dem vorliegenden
Beitrag sind FDM-Verstärkungsstrukturen aus dem Material Ultem 9085 dynamischen
Langzeituntersuchungen un-terzogen worden. Dabei wurde die innere Struktur der
Probekörper über eine Parametervariation verändert, sodass anschließend die signifikanten
Einflussfaktoren auf die Langzeitfestigkeit un-ter dynamischer Belastung identifiziert
und analysiert werden konnten. Mit dieser Vorgehens-weise sollte gleichzeitig
eine Optimierung der FDM-Verstärkungsstrukturen hinsichtlich der dy-namischen
Langzeiteigenschaften bei Biege- und Druckbelastungen vorgenommen werden. Des
Weiteren sind anhand der Probekörper die auftretenden Bruch- und Rissausbreitungsmechanis-men
analysiert worden. Anhand der ermittelten Wöhlerkurven kann die Lebensdauer unter
dy-namischer Belastung abgeschätzt werden. Außerdem zeigen die Untersuchungen,
dass Fehlstel-len durch eine hohe Strangbreite und Überfüllungen im Bauteil für
Schwachstellen in den FDM-Verstärkungsstrukturen sorgen, an denen Risse bei Druckbelastung
entstanden sind und sich dadurch schneller ausbreiten konnten.

text: The Arburg Plastic Freeforming (APF) is an additive manufacturing process
that allows three-dimensional, thermoplastic components to be produced in layer
by layer. The components are generated by depositing fine, molten plastic droplets.
One of the main advantages of the APF process is the open machine control. Thus,
the process parameters can be adapted and optimized for the individual applications.
The optimization is carried out on the basis of a variation of the process parameters
using a statistical design of experiments. Relevant process parameters are the
layer thickness, the form factor, the raster and delta angle as well as the overlap
between the contour and the filling of a layer. In addition, the nozzle and build
chamber temperatures are varied. Using this procedure, the effects of the influencing
parameters on the mechanical properties and the interactions between the influencing
parameters are analyzed and converted into mathematical models. On the basis of
the results and the models, guidelines will be developed to assist the user of
APF technology in the systematic process configuration for their own applications.
The material used is ABS, one of the most frequently used amorphous thermoplastics
in additive manufacturing. The mechanical properties are determined on the basis
of tensile tests and the characteristic values tensile strength, elongation at
break and Young's modulus. The results should show the performance of the APF
technology in regard to the mechanical properties.

text: CACC systems have been proven to increase road utilization, safety and decrease
fuel consumption by driving with a small headway at freeway speed. Such platooning
systems are usually focused on freeway scenarios and most of the current research
is done for this use case. Especially in urban scenarios at traffic lights and
intersections there is a lot of potential to increase the traffic efficiency and
safety by applying platooning mechanisms. Most of the techniques used on freeways
are not applicable for urban scenarios, as freeways are more or less a multi lane
one-way road. In my PhD project I want to investigate platooning as an application
for urban scenarios. For this I plan to examine platooning for signalized and
non-signalized intersections in a first step, but also consider platoon formation
strategies and driver models for human driven platoons. The end result should
be a set of algorithms and strategies to make urban and rural traffic more efficient
and safer by the use of platooning. Evaluation and analysis will mainly be done
by using simulations, but not limited to that.

text: Structural parts for aviation have very high demands on the development and
production process. Therefore, the entire process must be considered in order
to produce high-quality AM metal parts. In this case study, a conventional part
was selected to be optimized for AM. The process presented includes component
selection, design improvement with a novel approach for topology optimization
based on the AMendate algorithm as basis of MSC Apex Generative Design,component
production on a SLM 250 HL and post-processing including heat treatment and surface
smoothing. With the topology optimization a weight reduction of ~60 % could be
realized, whereby the stress distribution is more homogeneous. Furthermore, the
challenges of support optimization and post-processing have to be addressed, in
order to produce competitive parts.
