  1. 1. Collaboration Strategies of Foundation-owned Business Bodies Influencing Innovation : Innovation in foundation-owned businesses. Multi-case study on the collaboration strategies of the foundation-owned business bodies and their influence on innovation.

    University essay from Jönköping University/Internationella Handelshögskolan

    Author : Victoria Resch; Madeleine Stapfer; [2023]
    Keywords : foundation-owned business; family business; ownership; innovation; collaboration strategiess;

    Abstract : Background: Ongoing business transformations, labour shortages, and lack of resources are perceived as some of the business’s biggest challenges. Since innovation is a key driver for growth and profitability, it is indispensable for the long-term survival of a business. READ MORE

  3. 2. Continuous primitives with infinite derivatives

    University essay from Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakulteten

    Author : David Manolis; [2023]
    Keywords : Infinite derivative; Henstock–Kurzweil integral; primitive function; strong Luzin condition; variational measure;

    Abstract : In calculus the concept of an infinite derivative – i.e. DF(x) = ±∞ – is seldom studied due to a plethora of complications that arise from this definition. READ MORE

  4. 3. Predictive Modeling and Statistical Inference for CTA returns : A Hidden Markov Approach with Sparse Logistic Regression

    University essay from Umeå universitet/Institutionen för matematik och matematisk statistik

    Author : Oskar Fransson; [2023]
    Keywords : Probability theory; Statistical inference; finance; CTA; managed futures; machine learning; statistical learning; stochastic process; sparse logistic regression; Markov Chain Monte Carlo; Hidden Markov model;

    Abstract : This thesis focuses on predicting trends in Commodity Trading Advisors (CTAs), also known as trend-following hedge funds. The paper applies a Hidden Markov Model (HMM) for classifying trends. Additionally, by incorporating additional features, a regularized logistic regression model is used to enhance prediction capability. READ MORE

  5. 4. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lukas Jonasson; [2023]
    Keywords : Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Abstract : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. READ MORE

  6. 5. Scalable Nonparametric L1 Density Estimation via Sparse Subtree Partitioning

    University essay from Uppsala universitet/Statistik, AI och data science

    Author : Axel Sandstedt; [2023]
    Keywords : density estimation; scalable density estimation; nonparametric density estimation; scalable nonparametric density estimation; L1; L_1; anomaly detection; regression analysis;

    Abstract : We consider the construction of multivariate histogram estimators for any density f seeking to minimize its L1 distance to the true underlying density using arbitrarily large sample sizes. Theory for such estimators exist and the early stages of distributed implementations are available. READ MORE
