The three mechanisms that describe the reaction kinetics for various combustion processes were evaluated against experimental data for a reforming process. M1 is the GRI-Mech 3.0 mechanism, originally designed to model combustion of natural gas. The M2 mechanism originated from a methane combustion mechanism, which was extended to include reactions for methanol, acetaldehyde, ethanol, and ethylene
The design and synthesis of three star-shaped nonfullerene (NFA) acceptors, TPA-2T-INCN, TPA-2T-BAB, and TPA-T-INCN, based on a triphenylamine (TPA) core and linked through π-conjugated thiophene (T) spacers to different terminal units (3-oxo-2,3-dihydro-1H-inden-1-ylidene) malononitrile, INCN, and 1,3-dimethylbarbituric acid, BAB), are reported. These materials are blended with the widely used po
This article traces how African incomes have been measured through history, and shows that there has been a conflict of aims between producers and users of national income estimates. Politicians and international organizations seek income measures that reflect current political and economic priorities and achievements. Thus the importance given to markets, the state, and peasants in the estimates
Vid avgörande av frågor om bland annat vårdnad ska barnets bästa sättas i främsta rummet. Vid bedömningen av vad som är bäst för barnet är det viktigt att dess inställning klarläggs. Barnets rätt att komma till tals stadgas i artikel 12 i Barnkonventionen och i 6 kap. 2 a § FB. Hänsyn ska tas till barnets viljeyttring med beaktande av dess ålder och mognad. Både konventionstexten och föräldrabal
Corporate bankruptcy prediction has become a popular research topic since 1960s, and default risk management plays a more significant role among investors, debtors and the lenders. The Altman’s z-score model, the KMV model, and the Naïve model are well-known and widely used bankruptcy prediction models. This paper focuses on examining the bankruptcy prediction accuracy of these three models in the
Inom matematik och teknik är det vanligt att behöva lösa komplexa ekvationssystem. Dessa ekvationssystem uppkommer bland annat när man försöker göra simuleringar av till exempel vätskor eller gaser. Dessa ekvationssystem är många gånger mycket svårlösta, vilket innebär att de måste lösas med hjälp av datorer. En algoritm som ofta används till detta ändamål är Newtons metod som stegvis finner bättrIn this bachelor's thesis, different forcing term strategies for the inexact Newton method were evaluated on some standard test problems, the stationary p-Laplacian differential equation and the time-dependent Forchheimer equation. The forcing term strategies were initially studied by replicating experiments conducted by An, Mo and Liu (2005, Journal of Computational and Applied Mathematics)

With the rapid advancement of electromobility sector, the power density and heat generation of electronic chips is significantly rising. Due to its higher load and lower thermal mass, electronics chips in BEV inverters, such as MOSFETs, are increasingly susceptible to rapid temperature rises. Through the utilization of latent heat absorption, Phase Change Material (PCM) offers a promising passive
Breast cancer is the most frequently diagnosed form of cancer worldwide. 2 260 000 people were diagnosed with breast cancer year 2020, and 685 000 people deceased from it. In low income countries, breast cancer is commonly detected at a later stage when it is harder to treat, thus entailing a higher mortality rate. This is primarily due to the lack of knowledge and diagnostic tools available. A lo
Syftet med denna uppsats är att utreda hur synen på surrogatmoderskap har utvecklats i svensk rätt, och om avsaknaden av reglering av fastställande av utländskt moderskap är tillfredsställande. Frågan om avsaknaden av reglering ska ses i förhållande till barnets bästa och barnets rätt till respekt för privatliv enligt artikel 8 Europakonventionen (EKMR) för de barn som tillkommit genom surrogatmod
Barnkonventionen fick i januari 2020 status av lag i den svenska rätten eftersom lagstiftaren inte anser att den tidigare fått tillräckligt genomslag i tillämpningen. Barn har sedan länge behandlats som skilda från och underordnade vuxna. Barns underordning är antagligen den minst ifrågasatta maktordningen i samhället. Barn behandlas ofta som mindre vetande och deras inflytande begränsas regelmässIn January 2020, the Convention on the Rights of the Child was given the status of law in Sweden because the legislator was dissatisfied with the impact it had when applied as an international instrument. For a long time, children have been treated as separate from an inferior to adults. Children´s subordination is probably the least contested power structure in society. Children are often treated
Med konstitutionellt rättighetsskydd avses de regler och andra instrument som skapats för att skydda de konstitutionella rättigheter som ett lands författning tillförsäkrar dess medborgare, d.v.s. de grundläggande fri- och rättigheterna. I Sverige återfinns de konstitutionella rättigheterna i regeringsformen. De viktigaste instrumenten för konstitutionellt rättighetsskydd utgörs idag av Lagrådets
Denna uppsats tar sin utgångspunkt i den pågående debatten kring en tillgång till assisterad befruktning för ensamstående kvinnor. Assisterad befruktning är ett samlingsnamn för de metoder som finns för att avhjälpa ofrivillig barnlöshet och regleras i Sverige genom lag (2006:351) om genetisk integritet m.m. Frågan är aktuell eftersom riksdagen i mars 2012 gav regeringen i uppdrag att ta fram ett This thesis is based on the current Swedish debate about the ability of single women to access Assisted Reproductive Technology (ART). ART is a general term referring to methods used to overcome infertility by artificial means and is regulated by the Swedish Act (2006:351) on Genetic Integrity. The topic is relevant because the Swedish Parliament in March 2012 gave the government a directive to pr
To better predict the timely variation of algal blooms and other vital factors for safer drinking water production, a new AI scanning–focusing process was investigated for improving the simulation and prediction of algae counts. With a feedforward neural network (FNN) as a base, nerve cell numbers in the hidden layer and the permutation and combination of factors, etc., were fully scanned to selec
Debt and equity are in most countries treated differently for taxing purposes. The asymmetry between the financing forms are being taken advantage of by MNEs, allowing them to plan their cross-border activities in a way that lowers the taxable burden for the whole group. To prevent the increasing problem of base erosion and profit shifting, Member States have implemented different rules limiting i
Although Fourier Neural Operators (FNOs) are computationally efficient and theoretically mesh-independent, their standard formulation assumes periodic boundary conditions and rectangular domains. When applied to non-periodic conditions, FNOs often exhibit oscillations, edge effects, and reduced accuracy. To mitigate these issues, this study investigates modifications to the baseline FNO, including
