text: Moulding refers to a set of manufacturing techniques in which a mould, usually
a cavity or a solid frame, is used to shape a liquid or pliable material into
an object of the desired shape. The popularity of moulding comes from its effectiveness,
scalability and versatility in terms of employed materials. Its relevance as a
fabrication process is demonstrated by the extensive literature covering different
aspects related to mould design, from material flow simulation to the automation
of mould geometry design. In this state-of-the-art report, we provide an extensive
review of the automatic methods for the design of moulds, focusing on contributions
from a geometric perspective. We classify existing mould design methods based
on their computational approach and the nature of their target moulding process.
We summarize the relationships between computational approaches and moulding techniques,
highlighting their strengths and limitations. Finally, we discuss potential future
research directions.

text: This paper presents a method for designing planar multistable compliant structures.
Given a sequence of desired stable states and the corresponding poses of the structure,
we identify the topology and geometric realization of a mechanism—consisting of
bars and joints—that is able to physically reproduce the desired multistable behavior.
In order to solve this problem efficiently, we build on insights from minimally
rigid graph theory to identify simple but effective topologies for the mechanism.
We then optimize its geometric parameters, such as joint positions and bar lengths,
to obtain correct transitions between the given poses. Simultaneously, we ensure
adequate stability of each pose based on an effective approximate error metric
related to the elastic energy Hessian of the bars in the mechanism. As demonstrated
by our results, we obtain functional multistable mechanisms of manageable complexity
that can be fabricated using 3D printing. Further, we evaluated the effectiveness
of our method on a large number of examples in the simulation and fabricated several
physical prototypes.

text: The combined resection of skull-infiltrating tumours and immediate cranioplastic
reconstruction predominantly relies on freehand-moulded solutions. Techniques
that enable this procedure to be performed easily in routine clinical practice
would be useful. A cadaveric study was developed in which a new software tool
was used to perform single-stage reconstructions with prefabricated implants after
the resection of skull-infiltrating pathologies. A novel 3D visualization and
interaction framework was developed to create 10 virtual craniotomies in five
cadaveric specimens. Polyether ether ketone (PEEK) implants were manufactured
according to the bone defects. The image-guided craniotomy was reconstructed with
PEEK and compared to polymethyl methacrylate (PMMA). Navigational accuracy and
surgical precision were assessed. The PEEK workflow resulted in up to 10-fold
shorter reconstruction times than the standard technique. Surgical precision was
reflected by the mean 1.1 ± 0.29 mm distance between the virtual and real craniotomy,
with submillimetre precision in 50%. Assessment of the global offset between virtual
and actual craniotomy revealed an average shift of 4.5 ± 3.6 mm. The results validated
the ‘elective single-stage cranioplasty’ technique as a state-of-the-art virtual
planning method and surgical workflow. This patient-tailored workflow could significantly
reduce surgical times compared to the traditional, intraoperative acrylic moulding
method and may be an option for the reconstruction of bone defects in the craniofacial
region.

text: BACKGROUND:The introduction of image-guided methods to bypass surgery has
resulted in optimized preoperative identification of the recipients and excellent
patency rates. However, the recently presented methods have also been resource-consuming.
In the present study, we have reported a cost-efficient planning workflow for
extracranial-intracranial (EC-IC) revascularization combined with transdural indocyanine
green videoangiography (tICG-VA). METHODS:We performed a retrospective review
at a single tertiary referral center from 2011 to 2018. A novel software-derived
workflow was applied for 25 of 92 bypass procedures during the study period. The
precision and accuracy were assessed using tICG-VA identification of the cortical
recipients and a comparison of the virtual and actual data. The data from a control
group of 25 traditionally planned procedures were also matched. RESULTS:The intraoperative
transfer time of the calculated coordinates averaged 0.8 minute (range, 0.4-1.9
minutes). The definitive recipients matched the targeted branches in 80%, and
a neighboring branch was used in 16%. Our workflow led to a significant craniotomy
size reduction in the study group compared with that in the control group (P =
0.005). tICG-VA was successfully applied in 19 cases. An average of 2 potential
recipient arteries were identified transdurally, resulting in tailored durotomy
and 3 craniotomy adjustments. Follow-up patency results were available for 49
bypass surgeries, comprising 54 grafts. The overall patency rate was 91% at a
median follow-up period of 26 months. No significant difference was found in the
patency rate between the study and control groups (P = 0.317). CONCLUSIONS:Our
clinical results have validated the presented planning and surgical workflow and
support the routine implementation of tICG-VA for recipient identification before
durotomy.

text: We propose a novel generic shape optimization method for CAD models based
on the eXtended Finite Element Method (XFEM). Our method works directly on the
intersection between the model and a regular simulation grid, without the need
to mesh or remesh, thus removing a bottleneck of classical shape optimization
strategies. This is made possible by a novel hierarchical integration scheme that
accurately integrates finite element quantities with sub-element precision. For
optimization, we efficiently compute analytical shape derivatives of the entire
framework, from model intersection to integration rule generation and XFEM simulation.
Moreover, we describe a differentiable projection of shape parameters onto a constraint
manifold spanned by user-specified shape preservation, consistency, and manufacturability
constraints. We demonstrate the utility of our approach by optimizing mass distribution,
strength-to-weight ratio, and inverse elastic shape design objectives directly
on parameterized 3D CAD models.

text: "Additive manufacturing has recently seen drastic improvements in resolution,
making it now possible to fabricate features at scales of hundreds or even dozens
of nanometers, which previously required very expensive lithographic methods.\r\nAs
a result, additive manufacturing now seems poised for optical applications, including
those relevant to computer graphics, such as material design, as well as display
and imaging applications.\r\n \r\nIn this work, we explore the use of additive
manufacturing for generating structural colors, where the structures are designed
using a fabrication-aware optimization process.\r\nThis requires a combination
of full-wave simulation, a feasible parameterization of the design space, and
a tailored optimization procedure.\r\nMany of these components should be re-usable
for the design of other optical structures at this scale.\r\n \r\nWe show initial
results of material samples fabricated based on our designs.\r\nWhile these suffer
from the prototype character of state-of-the-art fabrication hardware, we believe
they clearly demonstrate the potential of additive nanofabrication for structural
colors and other graphics applications."

text: Molding is a popular mass production method, in which the initial expenses
for the mold are offset by the low per-unit production cost. However, the physical
fabrication constraints of the molding technique commonly restrict the shape of
moldable objects. For a complex shape, a decomposition of the object into moldable
parts is a common strategy to address these constraints, with plastic model kits
being a popular and illustrative example. However, conducting such a decomposition
requires considerable expertise, and it depends on the technical aspects of the
fabrication technique, as well as aesthetic considerations. We present an interactive
technique to create such decompositions for two-piece molding, in which each part
of the object is cast between two rigid mold pieces. Given the surface description
of an object, we decompose its thin-shell equivalent into moldable parts by first
performing a coarse decomposition and then utilizing an active contour model for
the boundaries between individual parts. Formulated as an optimization problem,
the movement of the contours is guided by an energy reflecting fabrication constraints
to ensure the moldability of each part. Simultaneously, the user is provided with
editing capabilities to enforce aesthetic guidelines. Our interactive interface
provides control of the contour positions by allowing, for example, the alignment
of part boundaries with object features. Our technique enables a novel workflow,
as it empowers novice users to explore the design space, and it generates fabrication-ready
two-piece molds that can be used either for casting or industrial injection molding
of free-form objects.

text: 'Objective: To report long-term results after Pipeline Embolization Device
(PED) implantation, characterize complex and standard aneurysms comprehensively,
and introduce a modified flow disruption scale. Methods: We retrospectively reviewed
a consecutive series of 40 patients harboring 59 aneurysms treated with 54 PEDs.
Aneurysm complexity was assessed using our proposed classification. Immediate
angiographic results were analyzed using previously published grading scales and
our novel flow disruption scale. Results: According to our new definition, 46
(78%) aneurysms were classified as complex. Most PED interventions were performed
in the paraophthalmic and cavernous internal carotid artery segments. Excellent
neurologic outcome (modified Rankin Scale 0 and 1) was observed in 94% of patients.
Our data showed low permanent procedure-related mortality (0%) and morbidity (3%)
rates. Long-term angiographic follow-up showed complete occlusion in 81% and near-total
obliteration in a further 14%. Complete obliteration after deployment of a single
PED was achieved in all standard aneurysms with 1-year follow-up. Our new scale
was an independent predictor of aneurysm occlusion in a multivariable analysis.
All aneurysms with a high flow disruption grade showed complete occlusion at follow-up
regardless of PED number or aneurysm complexity. Conclusions: Treatment with the
PED should be recognized as a primary management strategy for a highly selected
cohort with predominantly complex intracranial aneurysms. We further show that
a priori assessment of aneurysm complexity and our new postinterventional angiographic
flow disruption scale predict occlusion probability and may help to determine
the adequate number of per-aneurysm devices.'

text: " We present an interactive design system to create functional mechanical
\ objects. Our computational approach allows novice users to retarget an existing
mechanical template to a user-specified input shape. Our proposed representation
for a mechanical template encodes a parameterized mechanism, mechanical constraints
that ensure a physically valid configuration, spatial relationships of mechanical
parts to the user-provided shape, and functional constraints that specify an intended
functionality. We provide an intuitive interface and optimization-in-the-loop
approach for finding a valid configuration of the mechanism and the shape to
ensure that higher-level functional goals are met. Our algorithm interactively
optimizes the mechanism while the user manipulates the placement of mechanical
components and the shape. Our system allows users to efficiently explore various
design choices and to synthesize customized mechanical objects that can be fabricated
with rapid prototyping technologies. We demonstrate the efficacy of our approach
by retargeting various mechanical templates to different shapes and fabricating
the resulting functional mechanical objects.\r\n"

text: The accuracy of interdisciplinarity measurements is directly related to the
quality of the underlying bibliographic data. Existing indicators of interdisciplinarity
are not capable of reflecting the inaccuracies introduced by incorrect and incomplete
records because correct and complete bibliographic data can rarely be obtained.
This is the case for the Rao–Stirling index, which cannot handle references that
are not categorized into disciplinary fields. We introduce a method that addresses
this problem. It extends the Rao–Stirling index to acknowledge missing data by
calculating its interval of uncertainty using computational optimization. The
evaluation of our method indicates that the uncertainty interval is not only useful
for estimating the inaccuracy of interdisciplinarity measurements, but it also
delivers slightly more accurate aggregated interdisciplinarity measurements than
the Rao–Stirling index.

text: In this paper, we present a method for non-rigid, partial shape matching in
vector graphics. Given a user-specified query region in a 2D shape, similar regions
are found, even if they are non-linearly distorted. Furthermore, a non-linear
mapping is established between the query regions and these matches, which allows
the automatic transfer of editing operations such as texturing. This is achieved
by a two-step approach. First, pointwise correspondences between the query region
and the whole shape are established. The transformation parameters of these correspondences
are registered in an appropriate transformation space. For transformations between
similar regions, these parameters form surfaces in transformation space, which
are extracted in the second step of our method. The extracted regions may be related
to the query region by a non-rigid transform, enabling non-rigid shape matching.

text: This paper presents a parallel, implementation-friendly analytic visibility
method for triangular meshes. Together with an analytic filter convolution, it
allows for a fully analytic solution to anti-aliased 3D mesh rendering on parallel
hardware. Building on recent works in computational geometry, we present a new
edge-triangle intersection algorithm and a novel method to complete the boundaries
of all visible triangle regions after a hidden line elimination step. All stages
of the method are embarrassingly parallel and easily implementable on parallel
hardware. A GPU implementation is discussed and performance characteristics of
the method are shown and compared to traditional sampling-based rendering methods.

abstract:
- lang: eng
text: 'This paper presents an analytic formulation for anti-aliased sampling of
2D polygons and 3D polyhedra. Our framework allows the exact evaluation of the
convolution integral with a linear function defined on the polytopes. The filter
is a spherically symmetric polynomial of any order, supporting approximations
to refined variants such as the Mitchell-Netravali filter family. This enables
high-quality rasterization of triangles and tetrahedra with linearly interpolated
vertex values to regular and non-regular grids. A closed form solution of the
convolution is presented and an efficient implementation on the GPU using DirectX
and CUDA C is described. '
