Architectural muscle: The application of kinetic tensegrity elements on architectural flesh
(2025) Erenstedt, Oskar
Contemporary projects within kinetic architecture are primarily focused on
the facades of the buildings and less so on the buildings’ innards. Similarly
this theme of outward focus penetrates the architectural profession as a
whole leading to theories such as Architectural Flesh (Cruz, 2013) to emerge
as a reaction to this trend.
Therefore, this thesis undertook the task of imbuing the flesh of the structure
with kinetic elements to create a haptic relation between building and body
and promoting a healthier mindset for both. In doing so the continuation of
Architectural Flesh could be developed, Architectural Muscle.
To accomplish this the elements harness the movement of the inhabitants
to aid the building’s ventilation and create movement in the form of a pulse
for the building. This lessens the energy expenditure of the building while
evoking the sense of the building being alive, both which increases the
sustainability of the building. One directly through lowering emissions, the
other through an increased sense of empathy towards the building.
Physical modelling was integral to design a project which relies on several
moving mechanisms to function. The main element, the muscle, was
prototyped in accordance with human anatomy then placed into a platform
mechanism which was repeated along a static spine with supporting
functions. Enveloping this open air structure is a semi-transparent tensile
fabric displaying the inner workings of the structure. Each step of this
process has a prototype assigned to them to ensure their feasibility.
The result is a large structure spanning 140 meters with a width of 45 meters
inhabiting a Body Movement Centre housing 14 exercise halls and with the
capability to hold larger sporting events. The sense of motion is imbued
throughout the building from the outer facade to the inner functions.
Movement that creates an exchange between inhabitants and building
invoking a symbiotic relationship that ensures both’s longevity.
The resulting structure should be thought of as a prototype to be improved
upon and inspired by. It is merely a stepping stone towards the unreal living,
breathing and pulsating architecture that now is a little more real.
Globwood: Cellulose-glue binder for cordwood masonry
(2025) Stålhammar, Olof
Wood masonry is a building technique category that has existed in Europe and North America since the 1800s (Hagman, 2014); there are multiple names including cordwood masonry, stovewood masonry, and plank masonry that all describe similar and overlapping techniques. Cutoffs from the timber industry, stovewood, and reused materials can be used with a binder, primarily clay in Europe, or cement or lime mortars in North America to form walls. The walls can be load-bearing or be used as an infill in a load-bearing frame.
This thesis investigates alternative wood-based binders made from rest products from the wood industry to use in contemporary wood masonry construction with particular focus on hiking shelters along trails in Haninge through model making and testing of different recipes. The binders are tested for density, shrinking, and environmental stability.
A woodbased binder could have better insulating properties than clay, cement, or lime mortars allowing for buildings with better thermal properties while having a lower carbon footprint than existing binders.
This thesis finds that a binder using papier mache mixed with sawdust and lignin provides a good mix of strength and low shrinking. Experiments showcase that binders with a higher lignin content are more resistant to environmental effects.
The density of the binder mixtures suggest that binders with higher lignin content are stronger but have worse insulating properties than binders with correspondingly higher sawdust content.
The material is applied in the proposal of a hiking shelter and sauna, where the building technique is used in both traditional and novel ways..
Architect’s design code: Streamlining early-stage architectural workflow with parametric tools
(2025) Österman, Mattias
The Architect’s Design Code aims to research,
enhance and augment the architectural design
process by improving efficiency through
automated aid with the help of computational
tools. The tools and research conducted in
this paper serve as a framework for continued
research through a selection of explorations and
experiments, combined with a demonstration of
powerful computational modelling aids.
Over the past decades, digital development
has significantly improved workflows in the
architectural design process through software’s
such as AutoCAD, Rhino, SketchUp and Revit.
Despite these developments, the architecture field
has been slow at adapting to emerging technical
possibilities and the design process still involves
a considerable amount of time on procedures that
could be automated with parametric tools.
The aim of this thesis is to investigate how
parametric tools, in the form of developed
Grasshopper scripts, can streamline and automate
aspects of an architectural design process and
research how that affects the concept design
workflow. Through development of scripts with
different functions, designers can rapidly visualize
ideas and allocate more time exploring and/or
developing concepts while getting immediate
feedback on their ideas. Tools created in this thesis
were designed in a way to allow the user to have
full control over the design without requiring prior
computational experience.
In parallel to the tool development, a designbased
project was conducted to evaluate the
effectiveness of these tools. This project involves
the design of an activity center for the elderly,
located on an old boule-field in the small town of
Knivsta, Sweden.
The expected outcome of The Architect’s Design
Code is not to deliver a flawless set of design tools,
but rather to raise awareness and demonstrate the
potential of computational methods. By integrating
such tools, architects can reduce repetitive
workload, allowing them to focus on other critical
design tasks and better visualize their ideas.
Picking the raisins out of the cookie LiDAR based odometry in dynamic urban environments
(2025) Åberg, Andreas
Reliable localization using LiDAR on pedestrian-scale delivery robots in urban environments
poses distinctive challenges. Methods proven on larger vehicles with
high-end sensors do not necessarily translate to compact platforms with simpler
payloads. This thesis focuses on evaluating some state-of-the-art LiDAR odometry
approaches on a small delivery robot equipped with a LiDAR and other sensors such
as an IMU. By comparing trajectory accuracy, resilience to real-world motion profiles,
and multiple sensor configurations, insight is provided into which techniques
can serve as a reliable baseline and what additional capabilities are required to
achieve practical localization on often more resource-constrained robots.
Building on this foundation, we explore targeted enhancements driven by real-world
observations. We implement a real-time simple dynamic-object filtering approach
that operates in parallel with odometry, based on a range images, where moving
objects are subsequently identified and excised to maintain a static map. To further
mitigate drift over extended runs, we integrate loop-closure adjustments, detecting
and aligning previously visited areas to correct accumulated drift over larger
distances. Together, these refinements demonstrate how a robust baseline can be
augmented to meet the demands of odometry and mapping of a small delivery robot.
Attaining Organizational Alignment Between Top-Down Directives and Shop Floor Initiatives, A Case Study at a Manufacturing Plant
(2025) Arhall, Nora; Götberg, Anna
To achieve company goals, the top strategies should align with shop floor activities. In a large global organization, it is hard to align thousands of people to get them
to act in accordance with the same values and goals. This study investigated the main hinders and enablers by conducting a case study at a manufacturing plant
of a global company. The methods included analyzing key performance indicators, behaviors, and point of view of employees at all levels of the plant organization.
This study unveiled cultural clashes in an ongoing leadership shift that has led to a misalignment of expectations and inconsistencies of the way of working. There exist several best practices in the plant that are in accordance with existing research within cultural change and innovation, but to spread them and get the changes to
stick, the organization must be aligned.
