Spectral modeling of nebular-phase supernovae

Jerkstrand, Anders January 2011 (has links)
Massive stars live fast and die young. They shine furiously for a few million years, during which time they synthesize most of the heavy elements in the universe in their cores. They end by blowing themselves up in a powerful explosion known as a supernova (SN). During this process, the core collapses to a neutron star or a black hole, while the outer layers are expelled with velocities of thousands of kilometers per second. The resulting fireworks often outshine the entire host galaxy for many weeks. The explosion energy is eventually radiated away, but powering of the newborn nebula continues by radioactive isotopes synthesized in the explosion. The ejecta are now quite transparent, and we can see the material produced in the deep interiors of the star. To interpret the observations, detailed spectral modeling is needed. This thesis aims to develop and apply state-of-the-art computational tools for interpreting and modeling SN observations in the nebular phase. This requires calculation of the physical conditions throughout the nebula, including non-thermal processes from the radioactivity, thermal and statistical equilibrium, as well as radiative transport. The inclusion of multiline radiative transfer, which we compute with a Monte Carlo technique, represents one of the major advancements presented in this thesis. On February 23 1987, the first SN observable by the naked eye since 1604 exploded, SN 1987A. Its proximity has allowed unprecedented observations, which in turn have lead to significant advancements in our understanding of SN explosions. As a first application of our model, we analyze the 44Tipowered phase (t & 5 years) of SN 1987A. We find that a magnetic field is present in the nebula, trapping the positrons that provide the energy input, and resulting in strong iron lines in the spectrum. We determine the 44Ti mass to 1.5(+0.5−0.5)*10−4 M⊙. From the near-infrared spectrum at an age of 19 years, we identify strong emission lines from explosively synthesized metals such as silicon, calcium, and iron. We use integral-field spectroscopy to construct three-dimensional maps of the ejecta, showing a morphology suggesting an asymmetric explosion. The model is then applied to the close-by and well-observed Type IIP SN 2004et, analyzing its ultraviolet to mid-infrared evolution. Based on its Mg I] 4571 Å, Na I 5890, 5896 Å, [O I] 6300, 6364 Å, and [Ne II] 12.81 mm nebular emission lines, we determine its progenitor mass to be around 15 M⊙. We confirm that silicate dust, SiO, and CO have formed in the ejecta. Finally, the major optical emission lines in a sample of Type IIP SNe areanalyzed.We find that most spectral regions in Type IIP SNe are dominated by emission from the massive hydrogen envelope, which explains the relatively small variation seen in the sample. We also show that the similar line profiles seen from all elements suggest extensive mixing occurring in most hydrogenrich SNe. / At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Manuscript. Paper 4: Accepted.

The diploma thesis is focused on the Investors in People standard which is the only internationally recognized system for managing and developing human resources. It deals with the IIP characteristics, advantages, situation in the Czech Republic and its comparation with other models. In the practical part of the thesis the IPP influence is shown in the OLHO-Technik Czech, s.r.o. firm and the implementation process is described. The analysis was focused on the selected personnel processes and documentation in the firm based on the IPP principles. Finally the discussion with employees was made as a part of a qualitative research. The aim of the thesis is to approach the IIP standard to the Czech firms, support its diffusion and offer solution for improvement in the OLHO-Technik Czech, s.r.o. company in the HR field for consequential IIP recertification.

A Case Study of  Semi-Automatic Parallelization of  Divide and Conquer Algorithms Using Invasive Interactive Parallelization

Hansson, Erik January 2009 (has links)
<p>Since computers supporting parallel execution have become more and more common the last years, especially on the consumer market,  the need for methods and tools for parallelizing existing sequential programs has highly increased. Today there exist different methods of achieving this, in a more or less user friendly way. We have looked at one method, Invasive Interactive Parallelization (IIP), on a special problem area, divide and conquer algorithms, and performed a case study. This case study shows that by using IIP, sequential programs can be parallelized both for shared and distributed memory machines. We have focused on parallelizing Quick Sort for OpenMP and MPI environment using a tool, Reuseware, which is based on the concepts of Invasive Software Composition.</p>

AD/HD och känslomässigt undvikande : En naturalistisk pilotstudie om effekten av ISTDP för vuxna med AD/HD / AD/HD and emotional avoidance : A naturalistic pilot study on the effects of ISTDP on adults with AD/HD

Ermagan, Johannes January 2015 (has links)
Bakgrund: AD/HD innebär en funktionsnedsättning med kärnsymptom som ouppmärksamhet, hyperaktivitet och impulsivitet. Personer med AD/HD har också ofta problem med känsloreglering. Intensiv dynamisk korttidsterapi (ISTDP) syftar till att hjälpa patienter till ökad förmåga att uppleva komplexa känslor genom att medvetandegöra dem. Terapiformens utgångspunkt är att många patienters problem skapas av känslomässigt undvikande och den betonar värdet av upplevelse av känslor i terapirummet. Studien syftade till att undersöka effekten av ISTDP på symtomen hos patienter med AD/HD som ett komplement till sedvanlig medicinbehandling. Frågan var om behandling riktad mot känsloreglering påverkar den globala symptombilden för personer med AD/HD. Metod: Studien är en naturalistisk pilotstudie med sex patienter som fick 10 sessioners behandling med ISTDP. Utfallsmåtten var Inventory of Interpersonal Problems, Adult ADHD Self Report Scale, Beck Anxiety Inventory och Patient Health Questionnaire-9. Primärt utfallsmått var Adult ADHD Self Report Scale. Patientens problem mättes vid 4 tillfällen, vid första, fjärde, sjunde och sista veckan av behandlingen. Resultat: Patienterna förbättrades signifikant på Inventory of Interpersonal Problems och Adult ADHD Self Report Scale och på Beck Anxiety Inventory. Det fanns dock en stor variation inom gruppen. Vissa patienter förbättrades tydligt, andra förblev oförändrade och någon försämrades. Slutsatser: ISTDP som ett komplement till sedvanlig medicinbehandling och kan hjälpa vissa personer med AD/HD att fungera bättre interpersonellt. Det fanns också tecken på minskning av symptomen på AD/HD samt visar tendenser till reducerad ångest. Ingen följsamhetskattning till ISTDP gjordes. Detta samt det låga deltagarantalet och avsaknaden av kontrollgrupp gör att det är svårt att generalisera resultaten. De ska snarare ses som indikationer på vikten av ytterligare forskning.

Automated Reasoning Support for Invasive Interactive Parallelization

Moshir Moghaddam, Kianosh January 2012 (has links)
To parallelize a sequential source code, a parallelization strategy must be defined that transforms the sequential source code into an equivalent parallel version. Since parallelizing compilers can sometimes transform sequential loops and other well-structured codes into parallel ones automatically, we are interested in finding a solution to parallelize semi-automatically codes that compilers are not able to parallelize automatically, mostly because of weakness of classical data and control dependence analysis, in order to simplify the process of transforming the codes for programmers.Invasive Interactive Parallelization (IIP) hypothesizes that by using anintelligent system that guides the user through an interactive process one can boost parallelization in the above direction. The intelligent system's guidance relies on a classical code analysis and pre-defined parallelizing transformation sequences. To support its main hypothesis, IIP suggests to encode parallelizing transformation sequences in terms of IIP parallelization strategies that dictate default ways to parallelize various code patterns by using facts which have been obtained both from classical source code analysis and directly from the user.In this project, we investigate how automated reasoning can supportthe IIP method in order to parallelize a sequential code with an acceptable performance but faster than manual parallelization. We have looked at two special problem areas: Divide and conquer algorithms and loops in the source codes. Our focus is on parallelizing four sequential legacy C programs such as: Quick sort, Merge sort, Jacobi method and Matrix multipliation and summation for both OpenMP and MPI environment by developing an interactive parallelizing assistance tool that provides users with the assistanceneeded for parallelizing a sequential source code.
