Powertrain System Design for an Ultra-Light Electric Vehicle

This thesis focuses on the optimization of a dual-motor powertrain for an electric vehicle known as the LEVKART, a lightweight four-wheeled vehicle developed for both indoor and outdoor usage. The study examined the effect of different battery voltages, specifically 36 V, 39.6 V, and 43.2 V, on the vehicle’s performance. The main focus lies on reducing the energy consumption and increasing the ran

Gastrointestinal digestion and colonic fermentation : Beyond classic food science

Several digestive system models have been developed, varying in sophistication. These models measure under dynamic, semi-dynamic, or batch conditions, with notable distinctions between them. This chapter covers models for gastrointestinal digestion, including static and dynamic models, and important aspects of digestion and fermentation, such as bioaccessibility, bioavailability, and bioconversion

Cannibalization within a Multi-brand Portfolio – The Case of L'Oréal Group

Purpose: To investigate how the L'Oréal Group manages its multi-brand portfolio within the beauty market, focusing on how they navigate the complexities of brand cannibalization. Methodology: This paper employs a qualitative research method. Empirical data about the case object L'Oréal Group was collected through secondary data from their latest annual report, websites and online sources

The Role of Brand Logics in Shaping the Success of Brand Extensions: Apple vs. Colgate

Purpose: The purpose of this study is to investigate the impact of brand logics on the success of brand extensions. Methodology: This study has examined two different case studies to better understand the effect of brand logic. An extensive literature review was done on “brand logics”, specifically Unique Selling Proposition (USP) and the Golden Circle, “brand extensions” as well as “brand identit

Let's Get (Hyper)Physical: Defining a New Phenomenon

Purpose: To define hyperphysical retail, and present theoretical aspects which should be considered when a company wants to create their own hyperphysical installation. Methodology: A qualitative dual case study with secondary data utilizing an abductive method to develop the interpretation of the phenomenon by consistently working between the cases and the selected theories. Findings: This paper

The Phenomenon of First Hand Experiences With Brands

Purpose: The aim of this paper is to examine how organizations use live in-person events to increase brand awareness and long-term brand loyalty. Methodology: This paper utilizes a qualitative research method through the examination of three case studies: Red Bull Rampage, NHL Global Series, and Nike’s Breaking2 Marathon. The information for these case studies was gathered through secondary resear

From Copyright to Public Domain: How Brands Manage Iconic Characters Entering the Public Domain

Purpose: To examine how intellectual property rights holders and intellectual property rights experts view the phenomenon of characters’ copyright expirations. Research questions: How can intellectual property rights holders cope with the expiration of their characters’ copyright? What are the possible implications of copyright expiration for brands? Methodology: The study utilizes an inductive,

The genomic natural history of the aurochs

Now extinct, the aurochs (Bos primigenius) was a keystone species in prehistoric Eurasian and North African ecosystems, and the progenitor of cattle (Bos taurus), domesticates that have provided people with food and labour for millennia1. Here we analysed 38 ancient genomes and found 4 distinct population ancestries in the aurochs—European, Southwest Asian, North Asian and South Asian—each of whicNow extinct, the aurochs (Bos primigenius) was a keystone species in prehistoric Eurasian and North African ecosystems, and the progenitor of cattle (Bos taurus), domesticates that have provided people with food and labour for millennia1.

Vulnerable to heat stress : gaps in international standard metric thresholds

Exposure time to heat is increasing with climate change. Heat exposure thresholds are important to inform heat early warning systems, and legislation and guidance for safety in the workplace. It has already been stated that thresholds can be lower for vulnerable groups, including the elderly, pregnant women, children, and those with pre-existing medical conditions due to their reduced ability to t

On the Distance to Infeasibility in DC Power Grids with Constant-Power Loads

This paper is concerned with the feasibility of the power flow in DC power grids with constant power loads. We introduce the notion of distance to infeasibility as a voltage stability index and robustness measure for power flow feasibility. In particular, we study the p-norm distance to infeasibility in the domain of the constant power loads, and show how this distance may be expressed as a mathem

On the H2 optimal control of uniformly damped mass-spring networks

In this paper we provide an analytical solution to an H2 optimal control problem, that applies whenever the process corresponds to a uniformly damped network of masses and springs. The solution covers both stable and unstable systems, and illustrates analytically how damping affects the levels of achievable performance. Furthermore, the resulting optimal controllers can be synthesised using passiv

The relationship between preoperative sleep disturbance and acute postoperative pain control : A systematic review and meta-analysis

Poor preoperative sleep quality and impaired sleep continuity may heighten acute postoperative pain intensity and increase analgesic consumption, with negative implications for recovery, mental and physical health. The main objective of the current review was to investigate the relationship between preoperative sleep disturbance and acute postoperative pain control. Four electronic databases were

Nonlinear Wave Modulation for the Evaluation of Corroded Steel Plates Embedded in Concrete

Corrosion of steel components embedded in concrete is detrimental to the structural integrity and their intrinsic function,such as the leak-tightness of containment liners in nuclear reactor containment buildings. Detection of embedded linercorrosion is a challenging task due to the concrete’s heterogeneity and the large dimensions of containment buildings.This initial study explores early-stage d

Topological material in the III--V family : Heteroepitaxial InBi on InAs

InBi(0 0 1) is formed epitaxially on InAs(1 1 1)-A by depositing Bi onto an In-rich surface. Angle-resolved photoemission measurements reveal topological electronic surface states, close to the M high symmetry point. This demonstrates a heteroepitaxial system entirely in the III–V family with topological electronic properties. InBi shows coexistence of Bi and In surface terminations, in contradict

A Survey on Channel Sounding Technologies and Measurements for UAV-Assisted Communications

Unmanned aerial vehicles (UAVs) have been widely used in both military and civilian applications, where a stable communication link is vital for safe flight control and robust data transmission. To develop a reliable UAV communication system, it is necessary to deeply understand the UAV channel characteristics and establish accurate channel models. Channel sounding is the most effective way to obt

Polyvinyl fluoride: Predicting polarization in a complex soft matter system

We use first-principle density functional theory (DFT) to predict properties for semicrystalline polyvinyl fluoride (PVF) and compare with polyvinylidiene fluoride. We note that the crystalline regions of PVF are complex in the sense that we lack a complete experimental characterization of the detailed atomic organization. We therefore turn to DFT to predict both the structure and associated mater
