In this thesis, the information loss from the modified Mass-Drop tagging of a Z to qqbar jet is studied for a pp collision at LHC centre-of-mass energies in PYTHIA 8 using FastJet 3. The jet created by the Z has minimum transverse momentum of 200 GeV. This is then searched for subjets via two methods: a Cambridge/Aachen algorithm and a modified Mass-Drop Tagger with different z-cut values. The sub
In any storage ring or synchrotron based light source one of the most important factors for generating light with desirable properties is the electron beam itself. The dynamics of the beam must be properly characterised and, ideally, adjusted to the desired values for the light source to be able to deliver radiation of the quality which was decided during its design. This thesis is limited to som
This thesis research analyzed policies that promote resource mobilization for the development of the Solar Water Heaters and Photovoltaic industries in Mexico. The main inquiry is to identify the role that technological complexity plays in promoting resource mobilization for sustainable transition policies. It is assumed that if the technology is complex, resources are obtained from extra-regional
Purpose: The purpose of this research was to understand how customers construct the relationship, prior identified in the literature, between packaging, haptic sensory and perception with regard to FMCG products. Furthermore, we aimed to explore the role of haptic packaging characteristics on FMCG products for customers. Methodology: The philosophies of epistemology and ontology were considered b
Path integration is a navigational strategy that allows animals to return home in a straight line after an outbound journey, by integrating the distance and direction traveled. With their accessible brains, insects are the perfect model organisms to study this target-directed behavior at the neural level. The Central Complex (CX) is a group of neural structures (neuropils) in the insect brain suit
Denna avhandling föreställer sig en ny typ av typologi i staden, en som är sådd och odlad av och för de äldre och de unga. Ett mötesrum som främjar generationsöverskridande relationer och samarbete, samtidigt som det minskar ensamhet och främjar stimulerande miljöer för social utveckling. Genom att omvandla en oanvänd parkering i centrala Stockholm till ett gemensamt utrymme som är delvis trädgård
The main finding of this thesis is that the relevance and influence of Aaron Wildavsky’s book Searching for Safety in today’s safety discourse is limited although Wildavsky may be considered to be the linking pin between RE, HRO and NAT. The safety discourse may benefit from Wildavsky’s work in political science: I.e., dealing with social power within organizations, the use of net benefit in risk
The recognition of both inner (beliefs, mindsets, values) and outer dimensions (structures, technologies, behaviours) in addressing the climate crisis offers a powerful leverage point for the transformation needed. However, there is a lack of understanding of how this approach can be adapted to different groups and contexts. This thesis focuses on environmental activists from Russia as valuable ch
People are moving from rural to urban areas at an unprecedented rate, resulting in a high concentration of people subsisting on outside resources being constantly brought in. This presents a variety of complex sustainability problems. It is a resource-intensive system susceptible to supply shocks which could threaten food security. Many foods grow in cities, such as fruits on city trees, so utilis
In order to better understand impact of extreme weather events on condition of crop vegetation in Ukraine, analysis of agricultural droughts which occurred in the southern region of Ukraine, between years 2000-2012 was conducted in the current research. Method of the research In the current research, the impact of droughts was analyzed on yearly basis by assessing vegetation conditions and compar
Within the three key themes of Innovation & Design, Industry Relations, and Market Strategy, we have identified important factors for the survival of Apple as a niche player in a network economy. Concerning the theme of Innovation & Design the factors recognized are Radical Innovation, Resolving Schematic Incongruity, and Technological Evolution. Regarding Industry Relations we have found
This thesis examines the evolution of Policy Coherence for Development (PCD) in the EU. The overarching purpose is to give an example of ideational causation in the EU, and concretely, to illustrate how a norm can cause changes to policy and to policymaking. It is argued that the PCD concept is essentially a norm, because it provides a guideline for how to prioritize between differing and often co
Despite policy efforts to reduce waste and to recycle material, household waste in Europe continues to grow. In Sweden, most 290 municipalities use volume-based tariffs for household waste management. This report is about two alternative policies for household waste: (1) a weight based waste system and (2) a system of kerbside containers for sorted waste (FNI). It is a case study of policy develo
This report aims to investigate the possibilities to implement a high temperature heat pump at a Dow facility in Landskrona. By implementing a heat pump, waste heat from the production can be recovered and reused in the process. The question at issue is whether there will be enough energy available when needed due to an intermittent process, and if a heat pump will be feasible to implement. To inv
Simulations are an indispensable tool in physics because they complement experiments, especially complex ones. Coherent multidimensional spectroscopy (CMDS) is such a complex experimental setup. In CMDS, the molecular system of interest interacts with two to four coherent laser pulses and the generated emission provides information about the energetic structure and the relaxation dynamics of the p
While developing countries are faced with pressing socio-economic challenges, they are also increasingly vulnerable to the impacts of environmental degradation. Starting from this double challenge, current research has been focusing on the synergies between economic development and environmental protection. Within the field, the concept of environmental leapfrogging has emerged, referring to the p
Germany must decarbonise the heating of its buildings, now majorly dependent on natural gas, to meet its climate neutrality pledge. However, the share of natural gas-based heating has not been decreasing in the last decades, and Germany continuously failed to meet the building sector’s emission reduction targets. Moreover, the longevity of the gas and building infrastructure make the sector prone
