Many optimization models from practical problems are too bad to be worked by standard optimization techniques. Here the bad properties include nonconvexity and high discontinuity, such as the problem named low-rank recovery. The traditional approach, nuclear norm minimization, can solve the low-rank recovery but may contain bias. Algorithms like the FBS and the ADMM are highly effective in convex

Givet ett harmoniskt vektorfält u på en begränsad domän kallar vi den mängd där u träder in i domänen för inträdesrand och den mängd där u lämnar domänen utträdesrand. I den första delen av detta examensarbete ställer vi frågan om det är möjligt att ha inre stagnationspunkter och sammanhängande inträdes- och utträdesrand. Svaret i två dimensioner är ‘nej’ för en domän som är homeomorf till skivan.Given a harmonic vector field u on a bounded domain we call the set on which u enters the domain entrant boundary and the set on which u exits the domain emergent boundary. In the first part of this thesis we ask the question of whether it is possible to have interior stagnation points and connected entrant and emergent boundaries. The answer in two dimensions for a domain homeomorphic to a disc i

Denna uppsats syftar till att analysera hur Kunming-Montreal-ramverkets diskurser konstruerar och reglerar antaganden om transformativ förändring, specifikt ontologisk mångfald, i skyddet av den biologiska mångfalden. Vidare studeras hur dessa diskurser har formats, och formas av, rådande nyliberalism i miljöpolitik. Biologisk mångfald spelar en avgörande roll för exempelvis vår livsmedels- och va

In the rapidly evolving landscape of entrepreneurship, Artificial Intelligence (AI) has emerged as a pivotal tool reshaping how founders navigate uncertainty and allocate resources. Grounded in Sarasvathy’s dual logics of causation (predictive, goal-oriented planning) and effectuation (adaptive, resource-driven experimentation), this study investigates whether AI reinforces entrepreneurs’ default

This study examines the effect the ADHD traits hyperactivity/impulsivity and inattentiveness have on entrepreneurs during the planning of the pre-launch phase. Using Person-Environment Fit theory, Dual Pathway Model, and Coping-Dueling-Fit theory, this study explores how cognitive and emotional difficulties associated with ADHD impact entrepreneurial planning. The data was collected through a qual

There is still limited understanding of how entrepreneurial identity evolves over time and what the consequences of such changes are. Entrepreneurs in the creative industry is an interesting field to study identity work due to the ongoing tension between the commercial drive for growth and financial success and the creative pursuit of artistic authenticity and expression. This study, refers to the

Abstract Title: More Than Money: Human and Social Capital in Financing Swedish Innovative Small Enterprises. Seminar Date: 03/06 - 2025 Course: Degree Project: New Venture Creation- Entrepreneurship and Innovation, Lund University School of Economics and Management, 15 ECTS Authors: Daniel Milde & Gustav Lingevik Supervisor: Joakim Winborg Keywords: Entrepreneurial finance, Human capital, Soci

This thesis investigates how early-stage FinTech startups integrate Artificial Intelligence (AI) into strategic decision-making processes under conditions of uncertainty. By employing the OODA loop (Observe, Orient, Decide, Act) as a foundational framework, the study examines the evolving role of AI within each phase of the decision-making cycle. Drawing on nine in-depth interviews with founders a

Despite increased attention to gender equality in entrepreneurship, women remain significantly underrepresented in entrepreneurship and receive a disproportionately small share of funding. One underexplored factor contributing to this disparity is gendered questioning during investor pitches. The study aimed to explore how gendered questioning shapes confidence and self-perception, and to investig

This thesis explores how new ventures develop routines for using artificial intelligence (AI) in social media marketing. As AI tools become more accessible, many small companies begin using them without formal rules or training. The study focuses on small and medium-sized enterprises (SMEs) in the early stages of development and examines how AI use begins and spreads within teams. The research is

Early-stage apparel e-commerce ventures frequently struggle to achieve visibility in saturated digital markets with high degrees of societal noise. Hence, this thesis employs the Gioia (2013) methodology to conduct a qualitative multiple-case study in order to explore how resource-constrained entrepreneurs strategically respond to this challenge. The central research question addresses how early-s

Entrepreneurial intentions have been identified as a relevant precursor to entrepreneurial behavior; however, the complexities of entrepreneurial intention remain under-explored. This study examines the impact of offspring involvement with parental businesses on their entrepreneurial career intentions and the indirect roles of perceived desirability and perceived feasibility. Building primarily on

In today’s technology-driven classrooms, maintaining student focus is increasingly challenging. This study investigates the impact of "Focus room", a digital tool developed by Trelson, designed to reduce digital distractions and support sustained attention during class. Through an observational study in a Swedish school, four 8th grade student classes were observed before and during the

This project began with a comparative study of Hasami, one of Japan’s key ceramic production regions, and the ceramic tableware design of Nordic countries. By exploring their histories, cultural contexts, and design values, the project investigates how two geographically distant yet conceptually aligned traditions approach everyday objects. Through this cross-cultural lens, the project identifies

Background: Palliative care (PC) can alleviate suffering and improve quality of life. Yet, disparities persist, particularly in Honduras. Training efforts in PC for non-health caregivers have proven to reduce burnout and stress while enhancing the quality of life for both caregivers and patients. Purpose: This study aimed to explore the feasibility of a PC training program for non-health caregiver

Acute dyspnoea is one of the most common presenting symptoms in the emergency department (ED) and has a variety of underlying causes. Calprotectin is a neutrophil activation marker associated with adverse outcomes in acute cardiovascular and infectious diseases. However, the usefulness of calprotectin in the risk stratification of patients with acute dyspnoea is unknown. The objectives were to, in

Background: Hemodynamically obstructive coronary plaques may contain more vulnerable plaque characteristics than nonobstructive lesions. Objectives: The authors aimed to assess whether pressure-wire–based physiologic indices in nonculprit lesions are associated with vulnerable plaque characteristics. Methods: In the PROSPECT II study, patients with recent myocardial infarction underwent coronary a

The overall aim of this research project is to investigate whether new service value interventions on an individual level can lead to maintained or even increased mobility through ageing, but also to identify reduced costs for society (e.g. costs for transport services) and a transition from private car use to more sustainable transport. The purpose of this study is therefore to identify challenge
