  1. 1. Smartphone-based shade analysis using hemispherical fisheye imaging for local solar energy potential

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Jonas Andersson; [2020]
    Keywords : solar power; shading analysis; smartphone-based; fisheye lens; image segmentation; watershed transformation; Technology and Engineering;

    Abstract : In the emerging trend of smartphone use and a rising demand for solar photovoltaic (PV) power worldwide, this master thesis project explores the potential to utilize commercially available fisheye lens optics in combination with a smartphone camera to capture and analyze local shading conditions. Photogrammetric studies involving hemispherical sky photos have since long been used for environmental studies and solar energy applications, although mostly with high-end costly equipment.

  2. 2. Control Strategies for Variable Air Volume Ventilation used as a Demand Response Resource

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Ricky Klasson; Johan Frykebrant; [2020]
    Keywords : Technology and Engineering;

    Abstract : The Swedish power grid is actively balanced in order to maintain the nominal frequency of 50 Hz. Today, this is mostly done through flexible power generation. Emerging markets, allowing consuming resources to participate in balancing the grid, have the potential to increase the stability of the grid. READ MORE

  3. 3. Design of Two 28 GHz Doherty Power Amplifier Topologies with Vertical In(Ga)As Nanowire Transistors

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Simon Olson; Lucas Nilsson-Villoresi; [2020]
    Keywords : Doherty; PA; DPA; 28 GHz; Power amplifier; nanowire; transistor; In Ga As; Technology and Engineering;

    Abstract : In this Master’s thesis, two different 28 GHz Doherty power amplifiers (DPAs) are designed, for high power added efficiency (PAE), in the common source (CS) and cascoded topology respectively. The results are analyzed and compared between the two approaches. READ MORE

  4. 4. Modeling and Off-Design Prediction of an Organic Rankine Cycle

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Rasmus Nordberg; [2020]
    Keywords : Technology and Engineering;

    Abstract : The background for this master thesis project is a problem to describe performance of a small 150 kW organic Rankine cycle power plant. Climeon AB in Kista, has developed the unit, and the product is currently in use at different customers. The ”HP150” unit is made with a modular approach. READ MORE

  5. 5. Side Streams Throughout the Food Supply Chain in Västra Götaland - A Study of Reported Data, Interviews with Food Producers and a Simplified LCA Case Study

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Emma Kihlberg; [2020]
    Keywords : Food waste; Food loss; Side streams; Food supply chain; Västra Götaland; Food producers; LCA; Life cycle assessment; Sidoströmmar; Livsmedelskedjan; Livsmedelsproduktion; Livscykelanalys; Matsvinn; Matavfall; Technology and Engineering;

    Abstract : Vikten av resurseffektivitet i livsmedelskedjan är tydlig, eftersom denna sektor är en av de största bidragarna till negativ klimatpåverkan globalt. Målet med den här uppsatsen var att utforska sidoströmmar av mat inom livsmedelskedjan i Västra Götaland, för att kartlägga hur mycket som redan är täckt i statistiken och vilka luckor i datamaterialet som finns för framtida forskning att täcka.
