Innovation är ett vidkänt koncept som har fått ökad betydelse i dagens organisationer. Uppmärksamhet har framförallt riktats till de initiala faserna av innovationsprocessen, kallade Fuzzy Front End (FFE). Att hantera FFE effektivt har blivit nödvändigt i utvecklingen av nya innovativa produkter, eftersom det kan minska cykeltider och kostnader relaterat till produktutvecklingen. Det är dock svårtInnovation is a widely known concept which has received increased importance in today's organizations. Attention has especially been directed to the initial phases of the innovation process, commonly referred to as the Fuzzy Front End (FFE). Managing the FFE effectively, has become essential in the development of innovative products, since it can reduce cycle times and costs related to product

Achieving the 17 Sustainable Development Goals (SDGs) depends on timely and reliable information. However, standardized methodologies and regularly available data exist for only 40% of the 232 indicators. The “Data Revolution for Sustainable Development” is supposed to bridge these data gaps by harnessing ongoing developments in information technology, particularly big data. Currently existing pil

This study explores the implications of an encampment policy - criminalising refugees’ mobility beyond the borders of a camp - for the potential of Cash Based Transfer assistance in protracted refugee situations. As the success of Cash Based Transfer assistance implies market availability and access to commodities, and certain interaction between the host community and refugee population, it is ar

Emergency planning is required to respond to the increasing wildfire threat. A part of this is to assess a community’s capacity to move to a safe place during wildfires. This can be achieved by calculating the time it takes for a community to evacuate from an at-risk area to a relatively safe place. Simple approaches, such as the commonly used engineering calculation, may provide access to a broad

This thesis investigates the effectiveness of step size control in the numerical simulation of Stochastic Differential Equations (SDEs). The study is divided into a theoretical exploration and a series of numerical experiments. The theoretical section introduces key definitions and theorems, delves into the properties of Brownian motion, and examines the conditions under which solutions to SDEs ca

This study examines the impact of sky-bridges, as an egress component, on total evacuation of a high-rise building by using an evacuation model named Pathfinder. Five scenarios, with different combination of aspects such as height of the building, number of sky-bridges (and the subsequent inter-distance between them), and people allocation have been simulated. The comparison between the results fr

Sensing temperature is important for identifying preferable temperatures and avoiding dangerous extremes. The cold pain limit of mammals in general is estimated to approximately 12 °C. I reasoned that such a skin temperature is unlikely to be sustainable in colder climates and studied cold-adapted dogs in northern Sweden using thermography. Skin temperature on the rhinarium (naked nose tip) was 2.

This thesis explores the functionality of Extend Producer Responsibility (EPR) in the management of Electrical and Electronic waste (e-waste) in Kenya using a case study on manufacturer involvement in end-of-life management. To achieve the purpose of the study the analytical framework used incorporates Environmental effectiveness, Economic efficiency, Political acceptability, Administrabilty and I

Humanity is facing one of the greatest challenges ever. Climate change and global warming is a great risk and our consumption and dependency of fossil fuel are important causes of this accelerating issue. My thesis aims to design an entry for the professional debate about what urban areas in a fossil free future might be like. I’m investigating how an urban environment that requires as little tra

Detection of toxic hexavalent chromium in soil, groundwater, industrial effluent, etc., is of significant interest. We demonstrate the electrochemical detection of Cr(VI) using a surface-engineered mesoporous carbon-based material. The mesoporous carbon-based material is obtained by the controlled pyrolysis of a homogenous mixture of Fe and Co complexes of hydrolyzed collagen. The as-synthesized m

John Maynard Keynes was nominated for the Nobel Peace Prize in the 1920s for writing “The Economic Consequences of the Peace”. Yet, despite being highly ranked by the advisor of the Nobel Committee and placed on the shortlist, he did not win. This column brings out previously unused archival material from the Nobel Committee in Oslo to explore why. The Committee tended to withhold the Prize when c

Bifunctional DNA glycosylases employ an active site lysine or the N-terminus to form a Schiff base with an abasic (AP) site base excision repair intermediate. For 8-oxoguanine DNA glycosylase 1 (OGG1), cleaving this reversible structure is the rate-determining step in the initiation of 8-oxoguanine (8-oxoG) repair in DNA. Evolution has led OGG1 to use a product-assisted catalysis approach, where t

A high-resolution integrated bio-chemostratigraphic framework is established for the upper Tremadocian to lower Floian (Lower Ordovician) succession of the North China Block, based on new conodont and carbon isotope (δ13Ccarb) data from the Jiguanshan and Wudingshan sections in Liaoning Province, northeastern China. Thirty conodont species of 19 genera were identified from the two sections. Based

This article argues for a coalitional and comparative public theology as a new approach to the study of Global Christianity. This theology analyzes and assesses practices of living together in postmigrant societies. The article takes the shift from diverse migrant societies to superdiverse postmigrant societies that shapes many cities across Europe as a point of departure to scrutinize the role of

This paper examines the increasing use of bilateral investment treaties as instruments of foreign investment protection. The outcomes of treaty arbitrations are analysed to assess the extent to which treaties limit the economic policy choices available to host states. The disputes are also analysed to determine how such treaties may affect the development of legal institutions and the general appl

The chirality-flow formalism has proven to simplify the calculations of helicity amplitudes to the extent that the matrix element corresponding to a Feynman diagram can immediately be written down. It has also shown to speed up the computation of scattering amplitudes through numerical implementations in MadGraph5_aMC@NLO. In this thesis we investigate if automated computation of amplitudes can be

The transition to renewable energy is a critical element in global efforts to combat climate change. This study explores the decarbonization pathway for Peru’s energy sector, emphasizing renewable energy integration in the electricity generation sector. Peru's rich renewable resources—hydropower, wind, solar, geothermal and biomass—highlight its potential as a regional leader in sustainable en

In this project I investigate how architecture can give form to an institution that creates the conditions for negotiation between competing narratives. It is situated at Sillhovstomten, the contested site behind the Nationalmuseum in central Stockholm. The failed Nobel Center proposal on this site revealed that it is not an empty void awaiting to be filled, but a place where different political,

Background: Dietary management of phenylketonuria (PKU) focuses on restricting phenylalanine (Phe) intake. The European PKU guidelines and the PKU Dietary Handbook recommend a simplified PKU diet, allowing unrestricted consumption of many low-Phe foods, called free foods. While this approach may reduce the treatment burden for patients, its implementation varies. This study investigated practi
