  2. 11. Test Charge Response of a Dusty Plasma with Grain Size Distribution and Charging Dynamics

    Author : Muhammad Shafiq; Michael A. Raadu; Jens Juul Rasmussen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dusty plasmas; Complex plasmas; Grain size distribution; Grain charging dynamics; Lorentzian distribution; Kappa distribution; Test charge response; Delayed shielding; Energy loss; Drag force; Wake field.; Plasma physics; Plasmafysik;

    Abstract : This doctoral thesis reports analytical and numerical results for the electrostatic response of a dusty plasma to a moving test charge. Two important physical aspects of dusty plasmas, namely grain size distribution and grain charging dynamics were taken into account. READ MORE

  4. 12. On deoxidation practice and grain size of austenitic manganese steel

    Author : Dimitrios Siafakas; Anders Jarfors; Taishi Matsushita; Johan Nils Ahlström; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; carbides; oxides; Hadfield stål; desoxidering; kornstorlek; ympning; partiklar; karbider; oxider;

    Abstract : The exceptional wear resistance and work hardenability, place Hadfield steel as one of themost important materials for manufacturing cast components used in the mining, crashing,drilling, and excavation industries. In all metallic alloys used for component casting, themechanical properties are highly influenced by the microstructure of the material. READ MORE

  5. 13. Some Words on Cryptanalysis of Stream Ciphers

    Author : Alexander Maximov; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VMPC; Dragon; Grain; A5 1; SNOW 2.0; Scream; large distributions; correlation attacks; distinguishing attacks; algorithms; Cryptography; cryptanalysis; RC4; RC4A; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

    Abstract : In the world of cryptography, stream ciphers are known as primitives used to ensure privacy over a communication channel. One common way to build a stream cipher is to use a keystream generator to produce a pseudo-random sequence of symbols. READ MORE

  6. 14. ARSENIC REMOVAL BY PHYTOFILTRATION AND SILICON TREATMENT : A POTENTIAL SOLUTION FOR LOWERING ARSENIC CONCENTRATIONS IN FOOD CROPS

    Author : Arifin Sandhi; Gunnar Jacks; Gunno Renman; Maria Greger; Roger Herbert; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aquatic moss; grain; rice; lettuce; macrophyte; phytoremediation; speciation; temperature; oxygenation; wetland.; Land and Water Resources Engineering; Mark- och vattenteknik;

    Abstract : Use of arsenic-rich groundwater for crop irrigation can increase the arsenic (As) content in food crops and act as a carcinogen, compromising human health. Using aquatic plant based phytofiltration is a potential eco-technique for removing arsenic from water. READ MORE
