  1. 1. Predicting Electricity Consumption with ARIMA and Recurrent Neural Networks

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Klara Enerud; [2024]
    Nyckelord :time series forecasting; ARIMA; recurrent neural networks; LSTM; electricity forecasting; EED forecasting;

    Sammanfattning : Due to the growing share of renewable energy in countries' power systems, the need for precise forecasting of electricity consumption will increase. This paper considers two different approaches to time series forecasting, autoregressive moving average (ARMA) models and recurrent neural networks (RNNs). LÄS MER

  3. 2. Unleashing Profitability: Unraveling the Labor-R&D Nexus in SaaS Tech Firms : An Analysis of the Profitability Dynamics in SaaS Tech Firms through Stochastic Frontier

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :prashant Atla; Noräs Salman; [2023]
    Nyckelord :Employee growth; SaaS Industries; Profitability; Technical efficiency; Stochastic Frontier Analysis; Marginal Product of Labor; Panel data Models;

    Sammanfattning : Background: High-tech's rapid growth and prioritization of expansion over profitability can lead to vulnerability in economic downturns. The SaaS market, a part of the high-tech industry, offers affordable and flexible software solutions but is also susceptible to market volatility. LÄS MER

  4. 3. Characterization and Stabilization of Transverse Spatial Modes of Light in Few-Mode Optical Fibers

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Oscar Pihl; [2023]
    Nyckelord :spatial modes; Space division multiplexing; SDM; superpositions; LP-modes; few-mode fibers; quantum communication; quantum optics; adaptive optics; stochastic parallel gradient descent; SPGD; mode control; QKD; polarization controller; paddle controller; QRNG; quantum random number generator; spatial modes; perturbation effects;

    Sammanfattning : With the growing need for secure and high-capacity communications, innovative solutions are needed to meet the demands of tomorrow. One such innovation is to make use of the still unutilized spatial dimension of light in communications, which has promising applications in both enabling higher data traffic as well as the security protocols of the future in quantum communications.

  5. 4. Investigating the Estimation of the infection rate and the fraction of infections leading to death in epidemiological simulation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Jakob Gölén; [2023]
    Nyckelord :Epidemics; Compartmental Models; Parameter Inference; Synthetic Bootstrap; Infection Rate;

    Sammanfattning : The main goal of this project is to investigate the behaviors of parameters used when modeling an epidemic. A stochastic SIHDRe model is used to simulate how an epidemic evolves over time. LÄS MER

  7. 5. Quantum signatures in the work fluctuation-dissipation relation protocol

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

    Författare :Jian Li; [2023]
    Nyckelord :Quantum entanglement; fluctuation; coherence; quantum information; quantum thermodynamics; Physics and Astronomy;

    Sammanfattning : Quantum thermodynamics deals with the behavior of thermal machines that operate in the quantum regime, where coherences and entanglement can have a significant impact. However, detecting such quantum effects in thermal machines can be challenging, as they are primarily manifested as fluctuations. LÄS MER
