  1. 1. Remote MPPT measurementand logging system for solar modules

    University essay from

    Author : Viktor Westberg; Alexander Eklund; [2023]
    Keywords : MPPT; solar; LoRa; IoT;

    Abstract : We have designed and built a remote measurement system for evaluating the long-termperformance of solar photovoltaic (PV) modules. The system consists of a measurementdevice connected to the solar module which keeps the PV module at Maximum PowerPoint (MPP) and continuously measures the voltage and current at this point.

  3. 2. The Wall: The Right to Liberty and Security at the US–Mexico Border

    University essay from Göteborgs universitet/Institutionen för globala studier

    Author : Hanne Karlsson; [2021-07-01]
    Keywords : migration; US–Mexico border; migration; migrants; refugees; detention; asylum; non citizenship; securitization; social constructionism;

    Abstract : The migration and refugee situation on the US–Mexico border has been heavily debated and caused a lot of controversy in the last couple of years, much as a consequence of the Trump administration’s immigration policy and promise of a wall along the border. This thesis, therefore, aims to analyze how migrants’ and refugees’ right to liberty and security was affected by the way the Trump–government portrayed them, and the phenomenon of migration, as a security threat.

  4. 3. Maximum Predictability Portfolio Optimization

    University essay from KTH/Matematik (Avd.)

    Author : Nazim Huseynov; [2019]
    Keywords : Portfolio optimization; linear programming; multi-factor model; Portföljoptimering; linjär optimering; multifaktormodell;

    Abstract : Harry Markowitz work in the 50’s spring-boarded modernportfolio theory. It gives investors quantitative tools to compose and assessasset portfolios in a systematic fashion. The main idea of the Mean-Varianceframework is that composing an optimal portfolio is equivalent to solving aquadratic optimization problem. READ MORE

  5. 4. Evaluating the Economic Feasibility for utilizing PV Power Optimizers in Large-scale PV Plants for The Cases of Soiling, Mismatching, and Degradation

    University essay from Högskolan Dalarna/Energiteknik

    Author : MHD Mouaz Alhamwi; [2018]
    Keywords : Large-scale PV plants; Power optimizers; Inhomogeneous soiling; Degradation; Mismatching; Economic feasibility; LCOE; Feed-in tariff;

    Abstract : The solar PV modules are influenced by a variety of loss mechanisms by which the energy yield is affected. A PV system is the sum of individual PV modules which should ideally operate similarly, however, inhomogeneous soiling, mismatching, and degradation, which are the main focus in this study, lead to dissimilarities in PV modules operating behavior and thus, lead to losses which will be assessed intensively in terms of energy yield.

  6. 5. Statistical Analysis of Conductor-Musician Interaction : With a Focus on Musical Expression

    University essay from KTH/Datorseende och robotik, CVAP

    Author : Josefin Ahnlund; [2016]
    Keywords : music; interaction; statistical analysis; conductor; musical expression;

    Abstract : The kind of interaction occurring between a conductor and musicians while performing a musical piece together is an unique instance of human non-verbal communication. This Musical Production Process (MPP) thus provides an interesting area of research, both from a communication perspective and by its own right. READ MORE
