Žį ritušum viš rįšstefnugreinar um hvernig samhliša žróunarbestunarašferšir nżtast viš stikaval ķ stošvigravélum (greinar 23 og 27). 2003-2005 var unniš aš verkefninu Flokkun heilarita meš stošvigravélum ķ samvinnu viš Taugagreiningu h.f., sem sķšar varš hluti af VIASYS Healthcare. Verkefniš var styrkt af Markįętlun RANNĶS um upplżsingatękni. Sigrśn Dóra Sęvinsdóttir, tölvunarfręšingur, lauk ķ október 2004  viš M.S.-ritgerš ķ tengslum viš žetta verkefni. Rįšstefnugreinar 34 og 35 eru lķka afrakstur žessa verkefnis. 2004-2006 var unniš viš verkefniš, Heilaröskunar- og Alzheimergreining meš heilaritum, ķ samvinnu viš Kristin Johnsen, ešlisfręšing, hjį Lyfjažróun og Mentis Cura, og Jón Snędal öldrunarlękni į Landspķtala Hįskóla-sjśkrahśsi. Žaš verkefni var styrkt af Tęknižróunarsjóši RANNĶS. Steinn Gušmundsson, verkfręšingur, hóf doktorsnįm viš tölvunarfręšiskor ķ tengslum viš žetta verkefni ķ september 2004, en frį og meš įrinu 2006 vann hann aš doktorsritgerš um beitingu kjarnaašferša viš flokkun almennra tķmaraša, sem hann varši ķ maķ 2010. Rįšstefnugreinar 34, 35 og 44 og tķmaritsgreinar 41, 52 og 57 tengjast žessum rannsóknum.

Önnur verkefni į žessu sviši sem ég hef komiš aš eru fjögur meistaraverkefni viš tölvunarfręšiskor, verkefni Žóru Jónsdóttur um beitingu reiknigreindar viš aš greina batalķkur kvenna meš brjóstakrabbamein, sem hśn lauk viš 2006 og leiddi til rits 43, meistaraverkefni Pauls Gunnars Garšarssonar um vefnįm og vélręna auškenningu vélmenna, sem hann lauk ķ įrsbyrjun 2007, meistaraverkefni Hildar Sęvarsdóttur um beitingu grįkassaašferša  viš aš stżra olķnotkun flutningaskipa, sem leiddi til rits 46, og meistaraverkefni Stefįns Péturssonar um įhrif framhalla skipa į eldsneytiseyšslu sem hann lauk viš sumariš 2009 og leiddi til rits 51. Bęši sķšastnefndu verkefnin voru unnin ķ samvinnu viš fyrirtękiš Marorku.

B. Hönnun tölulegra ašferša til lausnar į jöfnum sem lżsa flutningi efna ķ grunnvatni og sjó og greining į eiginleikum žeirra.

Aš žessu verkefni hef ég unniš af og til allt frį įrinu 1978 ķ óformlegu samstarfi viš Snorra Pįl Kjaran, verkfręšing, og Verkfręšistofuna Vatnaskil. Helstu

ašferšalegu nżungarnar tengjast įkvöršun į flęši yfir jašra og hönnun į svonefndum uppstreymisnįlgunum. Rit 8 og 11 og fyrirlestur 2 fjalla um fyrra atrišiš, en fyrlestrar 4 og 6 um žaš sķšara. Bitastęšasti afraksturinn er hins vegar aš finna ķ forritapakkanum AQUA sem Verkfręšistofan Vatnaskil setti į alžjóšlegan markaš 1989 og ķ nżrri margra laga śtgįfa žess AQUA3D sem kom į markaš 1995. Rétt er aš taka fram aš ég į ekki beina ašild aš žvķ framtaki, žótt byggt sé į ašferšum sem ég hef hannaš. Skylt žessu er lķka verkefni, sem ég kom aš į įrunum 2010-2012 į vegum Vatnaskila og snżst um aš innleiša mešhöndlun į stefnuhįšu flęši ķ forritapakkann TOUGH2, sem er notašur vķša um lönd viš lķkangerš af jaršhitasvęšum. Tķmaritsgrein 62 fjallar um žaš efni.

C. Hönnun tölulegra ašferša til lausnar į jöfnum sem lżsa grunnsjįvarflęši og greining į eiginleikum žeirra.

Aš žessu verkefni hef ég unniš frį žvķ um 1984, aftur ķ óformlegu samstarfi viš Snorra Kjaran og Vatnaskil. Hér felast helstu ašferšalegu nżungarnar ķ mešferš svonefndrar öldujöfnu. Um žaš efni er fjallaš ķ ritum 13, 14 ,15, 16 og 17 og fyrirlestrum 8 og 10. Afrakstur žessarar vinnu birtist lķka ķ forritinu AQUASEA sem Verkfręšistofan Vatnaskil kom į alžjóšlegan markaš 1992. Lķkt og gildir um forritiš AQUA į ég žó ekki beinan žįtt aš žvķ framtaki. Upplżsingar um öll žessi forrit er aš finna į netinu undir slóšinni www.vatnaskil.is, žar meš talin stutt lżsing sem ég hef tekiš saman ķ handbókum meš forritunum um žau tölulegu lķkönum sem viš sögu koma. Ég hef lķka komiš aš żmsum stórum verkefnum sem Vatnaskilsmenn hafa unniš aš ķ tengslum viš žróun forritsins, svo sem lķkanreikningum į straumum ķ sundunum kringum Reykjavķk, ķ Mżvatni, ķ Hornafjaršarósi og ķ Gilsfirši.
Haustiš 1998 hófst ég handa viš hönnun og forritun į žrķvķšri lagskiptri gerš af AQUASEA og naut viš žaš ašstošar Andra Arnaldssonar, efnafręšings, jśnķ 1999- desember 2000, sem var į žessu tķmabili starfsmašur Vatnaskila. Fyrirlestur 13 fjallaši um žaš lķkan. Ég dvaldist viš Vešurstofu Danmerkur ķ mars og aprķl voriš 2005 viš frekari rannsóknir tengdar AQUASEA ķ samvinnu viš Nicolai Kliem, haffręšing. Fyrirlestur 14 fjallaši um nišurstöšur žeirrar vinnu. Į undnförnum įrum hefur annaš slagišveriš unniš aš samanburši į reiknislegri hagkvęmni viš aš beita annars vegar beinum ašferšum og hins vegar fólgnum ašferšum viš aš heilda lķkaniš įfram ķ tķma. Stefįn Žór Ragnarsson, stęršfręšingur, vann viš slķka athugun, meš styrk śr Nżsköpunarsjóši sumariš 2005 og Elvar Karl Bjarkason, jaršešlisfręšingur, vann aš skyldum athugunum į vegum Vatnaskila sumariš 2012. Žį hef ég einnig komiš aš śtvķkkunum į AQUASEA sem miša aš žvķ aš žaš nżtist betur viš lķkanreikninga į rennsli ķ įm og framburši žeirra. Žaš reiknilķkan hefur veriš kallaš AQUARIVER. Aškoma mķn aš grein 65 tengist lķka žessum rannsóknum.

D. Reiknilķkön af jökulflęši og vatnsrennsli  undir jökli.

Voriš 2009 hóf ég vinnu viš gerš reiknilķkans af vatnsrennsli undir jökli, aš frumkvęši Žrastar Žorsteinssonar, jöklafręšings. Lķkaniš er hlišstętt lķkani sem Glen Flowers, jöklafręšingur viš Simon Fraser University ķ Vancouver, hefur žróaš, hefur žróaš, en byggir į bśtareikningi į reglulegu žrķhyrninganeti. Žetta aušveldar tengingu viš reiknilķkan af jökulflęši sem byggir į hlišstęšum bśtareikningi, og var į įrunum 2004-2005 hannaš ķ samvinnu viš Gušfinnu Ašalgeirsdóttur, jöklafręšing og nśverandi dósent viš jaršvķsindadeild H.Ķ., og sķšan notaš af rannsóknahóp Helga Björnssonar, rannsóknaprófessors ķ jöklafręši viš Jaršvķsindastofnun H.Ķ., sbr. rit 56 og 63. Hiš óreglulega bśtanet skapar auk žess aukinn sveigjanleikja viš aš lķkja eftir vatnsrįsum sem geta hrķslast milli bśtanna. Viš heimsókn til Vancouver ķ maķ 2012 kom ķ ljós aš samstarfsmenn Gwen Flowers, Mauro Werder viš Simon Fraser University, og Christian Schoof og Ian Hewitt, viš University of British Columbia ķ Vancouver, hafa unniš aš hlišstęšum śtvķkkunum.

E. Reiknilķkön af göngum fiska.

Ég hóf haustiš 2000 į vegum reiknifręšistofu Raunvķsindastofnunar samstarf viš Kjartan G. Magnśsson, prófessor, um žetta verkefni, svo og sérfręšingana Simon Hubbard og Petro Babak, sem rįšnir voru sérstaklega til stofunnar vegna žess. Voriš 2002 hętti Simon en Eva Hlķn Dereksdóttir, verkfręšingur kom ķ hans staš og vann viš verkefniš fram ķ įrsbyrjun 2004. Žį kom Stefįn Freyr Gušmundsson, mastersnemi ķ stęršfręši, aš verkefninu meš hléum frį sumrinu 2002 og lauk viš meistararitgerš sem tengdist verkefninu 2009. Loks vann Baldvin Einarsson stęršfręšinemi viš verkefniš sumariš 2004  meš styrk frį Nżsköpunarsjóši nįmsmanna, og aftur sumariš 2005 meš styrk frį Rannsóknasjóši hįskólans. Verkefniš fól ķ sér aš kanna möguleika į gerš reiknilķkana sem lżsa göngum fiska, meš įherslu į lošnu, og nżtast sem hluti af stęrra evrópsku samstarfsverkefni, Development of structurally detailed statistically testable modelsof marine populations. Žvķ verkefni varr stżrt af Gunnari Stefįnssyni į vegum Hafrannsóknastofnunar og lauk formlega haustiš 2004. Skżrslur 22 og 29 og greinar  24, 25, 28 og 30, svo og fyrirlestrar 11 og 12 fjalla um mismunandi reiknilķkön sem hafa veriš žróuš ķ tengslum viš žetta verkefni. Kjartan lést langt fyrir aldur fram ķ janśar 2006, en ég var sķšan ķ samstarfi viš Björn Birnir, prófessor ķ stęršfręši, viš Santa Barbara hįskólann ķ Kalifornķu og gestaprófessor viš H.Ķ, og Hafrannsóknastofnun, viš aš žróa žessa lķkangerš okkar Kjartans įfram, rannsaka skölunareiginleika samverkandi eindalķkana og loks aš tengja žau viš lķkön af svonefndum kvikum orkubśskap til žess aš geta lķkt eftir breytingum ķ žroska fiskanna, sem hafa įhrif į gönguhegšan žeirra. Baldvin Einarsson vann aš žessu verkefni sem doktorsnemi viš H.Ķ. og Kalifornķuhįskólann ķ Santa Barbara, styrktur af Hafrannsóknastofnun og Eimskipafélagssjóši H.Ķ., og varši doktorsritgerš sķna um žetta efni frį H.Ķ ķ aprķl 2011. Alethea Barbaro, doktorsnemi Björns, sem lauk doktorsprófi ķ jśnķ 2008 frį Kalifornķuhįskólanum ķ Santa Barbara, kom lķka aš verkefninu og var ķ heimsókn viš H.Ķ sumurin 2007 og 2008. Greinar 48, 53 og 58 og rįšstefnugrein 50 er afrakstur žessarar vinnu.

F. Hönnun og bestun lķnulegra stżrikerfa.

Unniš ķ samvinnu viš Önnu Soffķu Hauksdóttur, prófessor viš rafmagns- og tölvuverkfręšideild H.Ķ., og nemendur hennar ķ framhaldsnįmi, Gķsla Herjóldfsson, sem lauk M.S.-nįmi ķ jślķ 2004 og var sķšan ķ doktorsnįmi, sem er ólokiš, Bergžór Ęvarsson, sem lauk M.S-nįmi ķ febrśar 2005, Helga Žorgilssonar, sem lauk M.S.-nįmi  2006 og Hinriks Inga Hinrikssonar, sem lauk M.S-nįmi 2010, auk żmissa B.S. nema. Unniš er aš žvķ aš žróa nżja framsetningu į żmsum verkefnum er lśta aš bestun lķnulegra stżrikerfa, bęši samfelldum og stakręnum, og byggja į lokušum formum viškomandi lausna, meš žaš aš markmiši aš leysa žau į hagkvęmari og markvissari hįtt en įšur. Sér ķ lagi er hugaš aš verkefnum sem lśta aš lķkansmękkun annars vegar og įkvöršun PID-stżringa hins vegar. Rįšstefnugreinar 31-33, 36-38, 40, 42, 45, 49, 54, 59,60, 67, 70, 71 og 72 og tķmaritsgrein 47 fjalla um žetta efni.

G. Reiknilķkan af losun lyfs śr marglaga himnu.

Unniš hefur veriš aš gerš reiknilķkans af losun lyfs śr marglaga himnu frį įrinu 2010 ķ samvinnu viš Fjólu Jónsdóttur, prófessor viš ķ išnašarverkfręši-, vélaverkfręši- og tölvunarfręšideild H.Ķ., Mį Mįsson, prófessor viš lyfjafręšideild H.Ķ. og Bergžóru Snorradóttur, doktorsnema hans, sem varši doktorsritgerš sķna ķ janśar 2014, og Kristins Gušnasonar, sem nś er ķ doktorsnįmi hjį Fjólu, auk žess sem Svetlana Solodova póstdoktor hjį Mį og meistaranemar Mįs og Fjólu hafa komiš aš verkefninu. Leitast er viš aš lķkja eftir nišurstöšum tilrauna um slķka losun, en markmišiš er aš hiš tölulega lķkan nżtist viš žróun marglaga lyfjalosunarkerfa sem geta višhaldiš föstum losunarstyrk til lengri tķma. Reiknilķkaniš byggir į nįlgunarašferš endanlegra bśta (finite elemant method) žar sem sérstaklega er tekiš tillit til ósamfelluskilyrša milli laga. Rįšstefnugreinar 55, 68 og 69 og tķmaritsgreinar 61, 63 og 66 fjalla um žetta višfangsefni. Frį įrinu hefur lķkaniš veriš śtvķkkaš ķ tvķvķš kerfi sem lżsa mį meš sķvalningshnitum meš snśningssamhverfu, Rįšstefnugreinar 68 og 69 fjalla um žaš.

H. Reiknidiffrun fylkjaašgerša.

Unniš hefur veriš aš žessu verkefni ķ samvinnu viš Kristjįn Jónasson, prófessor viš nįmsbraut ķ tölvunarfręši ķ H.Ķ. frį vorinu 2010. Verkefniš lżtur aš žvķ aš leiša śt formślur fyrir reiknidiffrun (algorithmic differentiation) helstu grunnašgerša fylkjareiknings, žannig aš žessar formślur geti nżtt sér žekkt grunnforrit fylkjareiknings, svonefnd BLAS-forrit, viš śreikningana, og bśa til forritasafn, hlišstętt BLAS-safninu, fyrir reiknidiffrunina. Stęršfręšinemarnir Pétur Orri Hauksson og Höršur Frey Yngvason, unnu viš gerš slķkra forrita sumariš 2010 og Höršur og Jón Blöndal, stęršfręšinemi, unnu įfram aš skyldu verkefni sumariš 2011, en nś er unniš aš endanlegum frįgangi safnsins og ritun greina til aš lżsa žvķ.

I. Jaršefnafręšilegir reikningar.

Um er aš ręša hönnun ašferša og forrita til žess aš įkvarša efnabreytingar og śtfellingar ķ heitu vatni, sem verša viš breytingar į hitastigi og žrżstingi. Žetta verkefni var unniš undir stjórn Stefįns Arnórssonar, einkum į 8. įratugnum, en sķšan hef ég einstaka sinnum veitt rįšgjöf ķ tengslum viš žaš. Helsta afrakstur mķns hluta er aš finna ķ ritum 5, 6 og 12. Frį haustinu 2001 hef  ég veriš ķ samstarfi viš Jón Örn Bjarnason, efnafręšing hjį Orkustofnun,  um reiknislega endurhönnun į forritinu WATCH frį grunni, en žaš er forrit sem hann gerši og byggši į ofangreindum ašferšum. Fyrir liggur hvernig haga skuli meginreikningum og žaš veriš śtfęrt og prófaš meš MATLAB-forritum. Jón Örn hefur sķšan unniš meš hléum aš endanlegu forriti sem er skrifaš ķ JAVA.

J. Endurbętt snjóflóšahęttumat.

Hér er um aš ręša starf hóps undir stjórn Kristjįns Jónassonar, sem hófst voriš 1995 žegar hann var settur prófessor viš hįskólann og hélt įfram mešan hann var įbyrgur fyrir hęttumati į Vešurstofu Ķslands 1996-1998 . Grunnhugmyndin fólst ķ svonefndum flutningi į snjóflóšaupplżsingum milli farvega meš ešlisfręšilegum snjóflóšalķkönum til žess aš geta nżtt į markvissari hįtt tiltęk gögn, og markmišiš var aš koma tölulegum kvarša į įhęttuna. Helsti afrakstur žessa starfs var fyrst gerš svonefndra rennslisstigakorta fyrir helstu snjóflóšabyggšir landsins, sem fylgdu riti 19, en sķšan vel skilgreindur framgangsmįti viš tölulega įkvöršun įhęttu sem lżst er ķ ritum  21 og 26, og hefur veriš ein helsta višmišunin sem notuš veršuš veršur viš nżtt hęttumat į sķšustu įrum. Žį fjallar rit 20 um žetta efni. Mešan Kristjįn var į Vešurstofunni varši ég auk žess umtalsveršum tķma ķ margs konar rįšgjöf ķ tengslum viš žróun hęttumatsins.

K. Netfręšilegar ašferšir viš lausn stórra rżrra jöfnuhneppa.

Žetta verkefni kom upp ķ tengslum viš hönnun forrita til tślkunar į jaršvišnįmsmęlingum, sem Ragnar Siguršsson, žįverandi starfsmašur Orkustofnunar, vann aš og var upphaflega unniš ķ samstarfi viš hann. Sķšan hef ég öšru hvoru hugaš aš žessu verkefni og fyrirlestrar 5 og 9 fjalla um žaš. Sverrir Žorvaldsson vann meš mér 1994 aš gerš greinar um žetta efni og žegar ég var ķ Bergen haustiš 1998 tók ég enn upp žrįšinn viš žetta verkefni ķ samvinnu viš ašila viš tölvunarfręšideildina žar.

L. Tölulegar ašferšir til lausnar stķfum afleišujöfnuhneppum.

Doktorsritgerš mķn fjallar um žetta efni svo og greinar 2 og 3. Sķšar hef ég öšru hverju hugaš aš žessu efni og fyrirlestrar 1, 3 og 7 fjalla um žaš. Ég hef hins vegar ekkert sinnt žvķ sķšan 1989.

M. Vešurfręšileg reiknilķkön.

Hér var hlutverk mitt fyrst og fremst veriš aš styšja Sigurš Žorsteinsson, vešurfręšing į Vešurstofu Ķslands, ķ vinnu hans viš lķkanreikninga į žessum svišum. Lķkanreikningar hans varšandi loftstrauma kringum fjöll eru reyndar nįskyldir margra laga sjįvarstraumalķkönum (sbr B). Rit 18 er afrakstur vinnu į žvķ sviši.

N. Mįltölvun.

Žetta var verkefni sem Baldur Jónsson var upphafsmašur aš og vann ķ samstarfi viš mig og Björn Ellertsson, einkum 1973-1975. Verkiš fólst ķ žvķ aš kanna möguleika žess aš nota tölvutękni viš textarannsóknir og aš safna saman żmsum įhugaveršum upplżsingum um tķšni orša og stafa sem nżst gętu viš frekari tölvutęka textavinnslu. Žįtt minn ķ žessu verku mį helst sjį af riti 10, sem kom śt nokkrum įrum seinna. Nżveriš hef ég aftur tengst verkefni af žessum toga, sem lżtur aš samhengishįšri villuleit į ljóslesnum texta og fjallaši meistaraverkefni Jóns Dašasonar, tölvunarfręšings, sem hann lauk viš ķ maķ 2012 um žaš efni. Kristķn Bjarnadóttir, sérfręšingur į stofnun Įrna Magnśssonar var mešleišbandi minn.

O. Önnur verkefni.

Hér mį helst tina til verkefni sem tengjast jaršešlisfręšilegri śrvinnslu frį žeim įrum žegar ég vann į Orkustofnun 1975-1978, en žį vann ég einkum aš verkefnum sem tengdust jaršvišnįmsmęlingum og žyngdarmęlingum auk jaršefnafręšilegra reikninga (sbr. G). Rit 7 og 9 eru frį žessum tķma. Į žessum įrum bjó ég einnig t.d. einnig til forrit til aš reikna śt stašsetningar fyrir stašsetningartęki sem Žorbjörn Sigurgeirsson hannaši.

Ritnefndarstörf

Sat ķ ritstjórn tķmaritsins BIT, sem er alžjóšlegt tķmarit ķ tölulegri greiningu meš norręnni ritstjórn, frį 1972 žar til ég lét af störfum nś ķ voriš 1995. Starfiš fólst einkum ķ ritrżningu greina og aš finna ašra ritrżnendur.

Sat ķ ritnefnd Tķmarits um raunvķsindi og stęršfręši frį 2003 til 2008.
