  1. 1. Predictive Modeling of Pipetting Dynamics. Multivariate Regression Analysis: PLS and ANN for Estimating Density and Volume from Pressure Recordings

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Lisa Linard Pedersen; [2024]
    Keywords : Technology and Engineering;

    Abstract : Thermo Fisher Scientific manufacture automatic pipetting instruments for diagnostic tests. These tests are sensitive to abnormalities and changes in e.g. volume or density could potentially lead to less precision or other issues in the pipetting work flow. READ MORE

  2. 2. Mängden död ved i värdekärnor i Söderåsens nationalpark

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Gustav Thurell; [2024]
    Keywords : volym död ved; stående död ved; liggande död ved; bokskog; nedbrytningsgrad; värdekärna;

    Abstract : There is a lack of knowledge about the development of the dead wood in former production beech (Fagus sylvatica) forests that have been protected. The present study has been carried out in Söderåsen National Park to compare the distribution of dead wood in relatively unaffected beech forests that have been protected for a long time (A-value cores) and older, previously managed beech forest that has only been protected for 20-30 years (B-value cores).

  3. 3. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Fritjof Nilsson; Yanjun Peng; [2023]
    Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

    Abstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

  4. 4. Benchmarking a 1 kW hybrid hydrogen fuel cell system

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Jonathan Envall; [2023]
    Keywords : PEMFC; fuel cell; UAV; hybrid; Technology and Engineering;

    Abstract : Unmanned Aerial Vehicles (UAV's) offer great versatility in the tasks that they may perform and they are today used in many sectors. The H24LEO project, administered by the Lund University School of Aviation, aims to develop and demonstrate a hybrid proton-exchange membrane fuel cell-powered UAV to aid in search and rescue operations performed by the Swedish Maritime Administration, and reduce the greenhouse gas emissions compared to similar work performed by helicopters.

  5. 5. Possible sugar substitutes to reduce sugar in bread : without affecting taste and quality

    University essay from SLU/Department of Molecular Sciences

    Author : Elin Forslund; [2023]
    Keywords : bread; sugar substitute; sugar reduction; inulin; oligofructose; amyloglucosidase; glucoamylase; dough; wheat dough; clean label;

    Abstract : The World Health Organization (WHO) is recommending a reduction of added sugars in food to decrease non-communicable diseases. This study was made in a collaboration with the bread company Pågen, who wants to reduce the added sugar, sucrose, to meet the recommendations from WHO and the consumer's wishes for less sugar in bread.
