An Investigation of Methods for Flow Measurements in a Gasketed Plate Heat Exchanger for Predictive Maintenance

For a company to stay relevant in the long term, it is essential to keep up with the latest technology and continuously consider new innovative solutions for improving products and services. The gasketed plate heat exchanger (GPHE) is a mechanical device, and this work attempts to investigate different possibilities for incorporating sensor devices and predictive maintenance systems to improve the

Hur resonerar svenska fastighetsbolag vid valet mellan intern och extern värdering av förvaltningsfastigheter?

Forskningsfrågor Hur resonerar svenska fastighetsbolag vid valet mellan intern och extern värdering av förvaltningsfastigheter? Hur resonerar fastighetsbolagen kring redovisningens kvalitativa egenskaper, relevans och tillförlitlighet? Syfte Uppsatsens syfte är att undersöka varför svenska fastighetsföretag väljer att anlita externa värderare. Studien syftar även till att undersöka hur fastighets

Experimental Study and Modelling of Heat Transfer in Milling of Titanium Alloys

The purpose of this project is studying heat transfer to indexable cutting tools during milling of a selection of titanium alloys, relevant to the industry. To achieve this goal, both experimental and theoretical models were contemplated to formulate the current thesis. The experimental set-up was designed and executed at Seco Tools AB, supporting the project as industrial collaborator. The therm

Performance and Wear Behaviour of Coated and Uncoated Cemented Carbide Tools during Milling of Titanium Alloys

Purpose – The purpose of this project is to study the performance of uncoated versus coated cemented carbide tools when performing milling operations in heat treated titanium alloys, with the goal of establishing a base line of knowledge and methodology linked to these difficult-to-machine materials relevant for the metal cutting industry. Design/methodology/approach – The work that is carried out

A preliminary study of evidence-based tool for wetland optimization - A case study using QSWAT+

Utförande av denna Masteruppsats är en del av projektet Ecodiver och i samarbete med vattenavdelningen på Lunds Tekniska Högskola. Syftet med studien är att granska den öppna källkods mjukvaran QSWAT+ som är ett plugin-program i QGIS. Detta för att i kommande tid kunna utveckla ett evidensbaserat verktyg för optimering av våtmarker. Undersökningsområdets omfattning är begränsad till Kävlingeåns avThis Master´s thesis is a part of the Ecodiver project, conducted by the Water department at LTH. The purpose of this study is to review the open-source software QSWAT+ as a plugin in QGIS, to be able to develop an evidence-based tool for optimization of wetlands. The scope of the study area is limited to the catchment area of Kävlinge river; however, no account is taken of the validation of data,

Examining the Evolution of Iran's Industrial Development under US-led Sanctions: A post-1979 perspective

The political and socioeconomic consequences of US-led sanctions on Iran have been extensively researched. Despite Iran's importance in natural resources such as oil, research on the domestic economic consequences of sanctions, particularly on Iranian industries, is largely disregarded. When the domestic perspective of the sanctioned country is factored out, socially recurring effects like sel

Analytics-enabled Green Supply Chain Management

The fashion industry with its complex supply chains deals with increasingly problematic environmental issues. IS and specifically analytics technologies are said to provide fashion companies with crucial insights to improve their environmental impact. However, these promises of this so-called analytics-enabled Green Supply Chain Management (GSCM) are not fully materializing in the European fashion

Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique

Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. The time-dependent polarisation state is investigated

Theoretical and numerical aspects of the pattern maximum likelihood estimator, with a view towards symmetric functionals estimation

Suppose that an infinite population is partitioned into different species. Given a random sample from the population of species, we are interested in estimating the species richness, which is the number of different species inhabiting a given area. The species richness is a symmetric functional of the probability mass function. A suitable model for estimating the probability mass function is via

Improvement of the Rucio implementation for the LDCS platform and search for dark data

In this work we aim to implement a software package to detect and categorize dark data, data not accessible or not known by the user, generated in the simulations of the Light Dark Matter eXperiment (LDMX). This will involve studying current existing solutions for such problems, attempting to implement them for the Lightweight Distributed Computing System (LDCS), and developing our own Dark Data S

Human capital and signalling theory. The communication mechanisms between fund seekers and backers in reward-based crowdfunding: a Swedish Kickstarter Campaigns data-based approach.

Purpose - Based on previous research, this study explores the importance of signals as a way to attract investment in Reward-based Crowdfunding by focusing on signalling theory. This study presents two hypotheses suggesting a positive relationship between Human Capital (defined as education and previous working experience) and the likelihood of success on Reward-based Crowdfunding. Methodology - T

Types of Impostor Phenomena: A Person-Oriented Approach to Impostor Phenomenon Using the Swedish Version of the Impostor Profile Scale

The Impostor Phenomenon is a concept that is well-known in pop-culture literature, but has received significantly less attention in academic contexts. Individuals experiencing the phenomenon have difficulty attributing their successes and achievements to personal factors and often feel like a fraud. The aim of this project was to contribute to the current literature on it, by both validating the S

Chasing the Rainbow when Implementing a Just Culture in European Air Traffic Management

In the wake of some high-profile accidents such as Gonesse (2000), Linate (2001) and Überlingen (2002), a trend of criminalisation of aviation professionals was noticeable. Recently, this trend was also seen in cases of operational incidents that did not lead to injury, loss of life or damage to property. This research explores whether the entry into force of Regulation (EU) No. 376/2014 of the Eu

Lower Barriers and Higher Social Status? — Chinese Women Working in E-commerce

With the recent development of Internet technology, the e-commerce industry is booming. However, under this rapid development, various inequality issues are hidden. Inspired by Goldin's (2002) study on declining gender significance, this paper focuses on the gender inequalities faced by female employees in the e-commerce industry in China. This paper focuses on one of the representatives of th
