This thesis explores the possibility for (re)defining the relationship between humans and robots with conversational interfaces. It does so by looking at the creation process of a voice and text-based virtual assistant for tourists from the perspective of critical posthumanism and posthuman performativity. In a reflexive fashion, I analyze my involvement in a tech start-up, in order to argue that,
Anthropogenic land-use covers a constantly increasing fraction of the terrestrial surface area. By employing a dynamic global vegetation model, human-induced changes in the terrestrial water balance as compared to an undisturbed scenario were simulated. The results suggest that humanity is a main driver of change in the terrestrial water balance in general and green water in particular. Most strik
Purpose and research question: The purpose of the study is to examine the effect ESG disclosure exerts on a firm’s propensity towards public or private debt. Methodology: For the panel data, pooled OLS and fixed effects models are applied. A quadratic term is introduced to test for non-linearity between bond debt ratios and ESG disclosure scores. An instrumental variable approach and a sharp regre
In this thesis methods for finding state space representation parameters for low inductance DC-motors are found and evaluated. Theory previously tested in simulations is verified experimentally and improved upon for both linear behaviour when the motor is controlled with a DC-source as well as nonlinear behaviour when controlled with pulse width modulation (PWM). For the linear behaviour a linear
In this thesis we show that the best forecast for near future yield curves are performed with a full specication of our chosen model and for far future yield curves the forecast is better with a partial specication of the model. We conclude that the driving factors for the banks' yield curves are not as closely related to Swedbank's as amongst the other peers which show that Swedbank stand
Material science has become an important research area in order to fulfill today’s requirements on lighter, cheaper and more sustainable materials. The European spallation source is a research center based on the world’s most powerful neutron source, which will enable new possibilities to evaluate material properties down to an atomic level. The linear accelerator (Linac), accelerates with help of
This paper investigates the characteristics and history of value added taxes. Many previous studies have focused on the theoretical implications of value added taxes; this paper differs in the method used as well as the phrasing of research question. This paper seeks out to answer whether a redesign of the current Value Added Tax system in Sweden could be a Pareto improvement. It looks at relevant
Purpose: The purpose of this thesis is to investigate whether the length of the maturity profile of a firm’s debt has any implications for the capital structure. Theoretical perspectives: A deductive approach, using econometric methodology to examine the correlation ( if any) between the selected variables, and the significance (if any) of that correlation. The output of our econometric model is f
The aims of the thesis are to investigate the estimation power and the normality of standardized residuals for Generalized autoregressive conditional heteroscedasticity models (GARCH). We facilitate the analysis by only dealing with GARCH(1, 1) models. We take use of MATLAB as the statistical programming tool for the simulation of the data and the estimation. We define the meaning of estimation
In the framework of this thesis, the optimization of the etching process of GaN for FinFET applications has been investigated. FinFETs are transistors with a vertical architecture in the shape of fins. These fins are fabricated by etching a pattern into a GaN substrate. The etching is carried out in two steps, a dry etch and a wet etch. In this thesis, these etching steps have been carried out whi
The building industry, like many others, are currently experiencing the effects of the digitalization, and the increased spread of smart buildings is a result of this. Much research has been done on smart buildings and their predecessors intelligent buildings, but there is limited research available on how entrance systems should be designed for smart buildings, especially regarding their connecte
Climate change is a long-term challenge that requires urgent actions. An increased amount of greenhouse gases in the atmosphere, causing changes in the climate system such as melting glaciers and extreme weather conditions, are correlated to economic growth. To mitigate climate change, there is a need to evolve efficient strategies to reduce greenhouse gas emissions from companies within all branc
The thesis introduces a range of communication protocols used to implementing smart homes currently available on the market. Two protocols are chosen and theoretically analysed in depth. The analysis both describes how the protocols works and describes the measures taken in order to protect it against attacks from third parties. The theoretical evaluation analyses how susceptible the protocols are
Direct Fastening tools are popular for quick fastenings in concrete and steel by propelling the nail with gun powder, gas or electricity. Because of this the users hand needs to absorb a shock caused by the recoil when a setting is performed. The link between the recoil and its effect on the user is essentially unexplored. This makes it hard to design an optimum handle for a direct fastening tool
Phosphate is fundamental for optimal growth and reproduction for plants. However, due to low solubility, not all phosphorus in the soil is available to the plant. It has recently been discovered that plants can take up complex phosphate-containing organic compounds, such as phospholipids. This depends on membrane transporters, more specifically lipid flippases. In the model plant Arabidopsis, the
This thesis examines the possible transjudicial interaction that may arise between the ICC and the IACtHR with regard to the interpretation of the crime of enforced disappearance of persons. This potential scenario of jurisprudential cross-fertilisation is considered on the fact that both, the IACtHR and the ICC exercise jurisdiction ratione materiae over the crime of enforced disappearance, there
Fermented dairy products are wildly consumable products in today societies, and these products are known for their unique rheological properties due to the complex structural systems they possess. The simplest rheological model for describing yogurt behavior is the Power Law model, but this model parameters are not sufficient for describing the complex behavior during flow and filling. Therefore,
Since the purchasing expenditure of many companies is such a large part of the total cost and 99,8 % of companies are classified as Small and Medium Sized Enterprises (SME), one might expect that theories on purchasing strategy would not only be conducted for large companies but also SMEs. In order to fill this gap in theory, this thesis aims to create a purchasing strategy framework for SMEs in t
Title: System Dynamics Perspective on the Business Model for Sustainability: A Multiple Case Study in the Architecture Industry Purpose: The primary purpose of the study is to explain how the system dynamics between the Value Configuration, Partner Network, and Capabilities work in a Business Model for Sustainability of small and large architecture firms. Methodology: We followed an abductive, q
