This paper presents the development of a non-dimensional model of a continuous cross-flow atomic layer deposition (ALD) reactor with temporally separated precursor pulsing and a structured model-based methodology for scaling up the substrate dimensions. The model incorporates an ALD gas–surface reaction kinetic mechanism for the deposition of thin ZnO films from Zn(C2H5)2 and H2O precursors that w
A fundamental part of many computer algorithms involves traversing a binary tree. One notable example is traversing a space-partitioning acceleration structure when computing ray-traced images. Traditionally, the traversal requires a stack to be temporarily stored for each ray, which results in both additional storage and memory-bandwidth usage. We present a novel algorithm for traversing a binary
The purpose of this study was to examine the socio-economic problems faced by urban refugees with a case study of Kampala Uganda. Under this topic, participants were asked why they live in unrecognized areas, why they never lived in settlements and why urban refugees are not visible to humanitarian agencies. The study went ahead to investigate the socio-economic problems refugees were facing as we
The Rheology of asphalt binders is crucial for the function and durability of road pavements. In the American road concept Superpave, which has been in use for about 20 years, old empirical methods has been replaced with a rheological measurement technology in the form of DSR. With this technology, the functional properties of binders are described in basic rheological terms. The department of Tec
Abstract The aim of this bachelor thesis is to examine and analyze the existing knowledge concerning how a functional kennel should be constructed for sled dogs living outdoors. I interviewed subjects related to this area such as a construction engineer, a veterinarian, the Swedish supervisory authority and sled dog owners. A calculation model has been used to estimate which thermal aspects affect
Hagastaden is a urban construction project for housing and workplaces, divided between the municipalities Solna stad and Stockholms stad, in Sweden. The building started in 2017 and will be finished in 2025. The project involves many actors including the municipalities. Hagastaden is supposed to be a very densified area, which is stated by the Stockholm municipality it self will lead to a smaller
Injuries to the Anterior Cruciate Ligament (ACL) are severe and common among the physically active young to middle aged population. After suffering from such an injury, the patient typically face a lengthy rehabilitation process. Usually, it takes 1-2 years before an injured knee returns to pre-injury performance, if that is ever achieved. The risk of re-injury is high and is increased by early re
Aim: Phantoms are used daily in the clinic for radiotherapy. As more realistic phantoms are requested, 3D printing could be used but the design of a realistic phantom is difficult. The purpose of this project was to design and 3D print an anthropomorphic phantom that could be used for verification of complex treatment such as stereotactic arrhythmic radioablation treatments without the use of pati

To systematically address non-technical engineering skills (NTES), six mandatory "Engineering Days" (Ing-dagar) were introduced in two bachelor programmes. The students were also allowed to perform voluntary activities leading to a Certification of Non-technical Engineering Competences, a certificate the students can attach to their CVs. To be certified, the student must have performed activities
Systems mixing Boolean logic and arithmetic have been a long-standing challenge for verification tools such as SAT-based bit-vector solvers. Though SAT solvers can be highly efficient for Boolean reasoning, they scale poorly once multiplication is involved. Algebraic methods using Gröbner basis reduction have recently been used to efficiently verify multiplier circuits in isolation, but generally
Sliding mode control (SMC) is to keep the system to a stable differential manifold. Model predictive control (MPC) calculates the control input by solving an optimization problem on receding horizon. The method of receding horizon sliding control (RHSC) includes the predicted information into the SMC design by combining SMC and MPC. Considering the modeling error and measurement noise, there are m
The min-sum (MS) and approximate-min* (a-min*) algorithms are alternatives of the belief propagation (BP) algorithm for decoding low-density parity-check (LDPC) codes. To lower the BP decoding complexity, both algorithms compute two magnitudes at each check node (CN) and pass them to the neighboring variable nodes (VNs).In this work we propose a new algorithm, ga-min*, that generalizes the MS
Conflict-driven pseudo-Boolean solvers optimize 0-1 integer linear programs by extending the conflict-driven clause learning (CDCL) paradigm from SAT solving. Though pseudo-Boolean solvers have the potential to be exponentially more efficient than CDCL solvers in theory, in practice they can sometimes get hopelessly stuck even when the linear programming (LP) relaxation is infeasible over the real
We see a potential for ESS to benefit from sharing alarm data for machine learning applications, by establishing data ecosystem. To achieve these goal, ESS must make a strategic decision to pursue data sharing, establish a technical platform to share a digital twin, continue advancing the data ecosystem, and work towards a standardized reference model.
One type of light source that remains largely unexplored in the field of light transport rendering is the light generated by superluminal particles, a phenomenon more commonly known as Cherenkov radiation. By re-purposing the Frank-Tamm equation for rendering, the energy output of these particles can be estimated and consequently mapped to photons, making it possible to visualize the brilliant blu
We establish an exactly tight relation between reversiblepebblings of graphs and Nullstellensatz refutations of pebbling formulas,showing that a graph G can be reversibly pebbled in time t and space s if and only if there is a Nullstellensatz refutation of the pebbling formulaover G in size t + 1 and degree s (independently of the field in whichthe Nullstellensatz refutation is made). We use this
In this paper we propose a design methodology to partition dataflow applications on a multi clock domain architecture. This work shows how starting from a high level dataflow representation of a dynamic program it is possible to reduce the overall power consumption without impacting the performances. Two different approaches are illustrated, both based on the post-processing and analysis of the ca
In this paper, we present a systematic approach to design a compact dual-mode monopole-like patch antenna using characteristic mode analysis (CMA). The modal analysis of a slotted circular patch structure incorporating a new shorting pin loading technique is presented. To achieve a compact monopole-like antenna with wideband operation, it is demonstrated that the first two significant modes with m
