  1. 1. Jet fragmentation in shaped charges

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Joakim Ericson; [2022]
    Nyckelord :Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

    Sammanfattning : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. LÄS MER

  3. 2. Development of grout for deep shaft

    M1-uppsats, KTH/Byggteknik och design

    Författare :Karl Lindberg; Adam von Krusenstierna; [2021]
    Nyckelord :Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

    Sammanfattning : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. LÄS MER

  4. 3. Synthesis and Characterization of some Photo-CORM and Photosensitizers

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Joachim Björklund; [2019]
    Nyckelord :Inorganic Chemistry; Bioinorganic Chemistry; CORM; Photo-CORM; Photosensitizers; Synthesis; Characterization; Oorganisk kemi; Chemistry;

    Sammanfattning : It is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is the fact that it is not trivial to control the volume of gas inhaled, compromising its use as a therapeutic agent. LÄS MER

  5. 4. A techno-economic comparison between outdoor macro-cellular and indoor offloading solutions

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Feidias Moulianitakis; [2015]
    Nyckelord :Mobile broadband; indoor environment; femtocells; WiFi APs; carrier aggregation; capacity.; mobilt bredband; inomhusmiljö; femotceller; WiFi APs; carrier aggregation; kapacitet.;

    Sammanfattning : Mobile penetration rates have already exceeded 100% in many countries. Nowadays, mobile phones are part of our daily lives not only for voice or short text messages but for a plethora of multimedia services they provide via their internet connection. LÄS MER

  7. 5. Beräkningsmodeller för riktad sprängverkan vid ammunitionsröjning

    Kandidat-uppsats, Försvarshögskolan

    Författare :Fredrik Johnsson; [2012]
    Nyckelord :SC; shaped charge; jet penetration depth; stand-off distance; explosive ordnance disposal; measures for hazard confinement; protective measures; hazardous area; RSV; riktad sprängverkan; penetrationsförmåga; detonationsavstånd; ammunitionsröjning; skadebegränsande åtgärder; skyddsåtgärder; riskområde;

    Sammanfattning : I arbetet görs en ansats att utveckla verktyg för dimensionering av skyddsåtgärder vid röjning av RSV-ammunition. Till skillnad mot övriga verkansformer så saknar ammunitionsröjaren idag beräkningsmodeller eller annat adekvat stöd för fastställande av maximalt riskområde respektive för dimensionering av skadebegränsande åtgärder vid röjning av ammunition innehållande riktad sprängverkan.
