  1. 1. Sodium Model for Production Planning in a Paper Mill

    University essay from Umeå universitet/Institutionen för fysik

    Author : Isak Lindfors; [2022]
    Keywords : Paper Mill; Production Planning; Modelling; Liquor; Sodium;

    Abstract : In today’s pulp and paper industry the Kraft process is the most common method for pulp production. This method uses sodium based chemicals (white liquor) in the cooking process to remove lignin from the wood chips and create pulp. READ MORE

  3. 2. Visibility in Smoke With Different Extinction Coefficients

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Lea Elhokayem; [2022]
    Keywords : Visibility; smoke; exit sign; extinction coefficient; visibility constant; evacuation; Technology and Engineering;

    Abstract : Visibility in smoke has since the 1970s gained some attention, mostly after Tadahisa Jin ran the experiments which helped him develop todays widely used visibility equation. By showing that visibility can be assumed to be inversely proportional to the extinction coefficient by a visibility constant (equal to 8 for light emitting sign and 3 for light reflecting), Jin opened up new doors for researchers who were testing out his theory by going around experimenting in different ways and also by showing that there is way for more research to be done.

  4. 3. On the statistics and practical application of the reassignment method for Gabor spectrograms

    University essay from Lunds universitet/Matematisk statistik

    Author : Erik. M Månsson; [2019]
    Keywords : Mathematics and Statistics;

    Abstract : The reassignment method is a technique for improving the concentration of signals in spectrograms and other time-frequency representations (TFR). It achieves this by displacing the points in a TFR according to the reassignment vector for every point. READ MORE

  5. 4. All solid state single-shot Dispersion scan (D-Scan) for ultrashort laser pulses

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Shekhar Jadhav; [2019]
    Keywords : Dispersion scan; d-scan; Single shot d-scan; Si-scan; Physics and Astronomy;

    Abstract : Ultrashort laser pulses play an important role in many applications in science and technology, from attosecond science to time resolved spectroscopy and material processing. For applications of ultrashort laser pulses, it requires a complete characterization of the electric field of the pulse, which includes both phase and amplitude of the electric field. READ MORE

  6. 5. The Point-Split Method and the Linking Number of Space Curves

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Timmy Forsberg; [2014]
    Keywords : Links; The Linking Number; Gauss Linking number; Point-split method; point-splitting; White s formula; C ̆alug ̆areanu; Calugareanu s relation; Twist; Writhe; twisting; Writhing;

    Abstract : This is a report on research done in the field of mathematical physics. It is an investigation of the concept of the linking number between two simple and closed spatial curves. The linking number is a topological invariant with scientific applications ranging from DNA biology to Topological Quantum Field Theory. READ MORE
