This thesis compares Auto Regressive Moving Average (ARMA) and Generalized Auto Regressive Conditional Heteroscedacity (GARCH) models for three metal commodities. ARMA models have an unconditionally non-random and constant variance, which typically serves well in effectively representing homoscedastic data. The GARCH models feature variable variance that is non-random when conditioning on the past
Background: Under inflammatory conditions, T cell-dependent (TD) protein antigens induce proinflammatory T-and B-cell responses. In contrast, tolerance induction by TD antigens without costimulation triggers the development of regulatory T cells. Under both conditions, IgG antibodies are generated, but whether they have different immunoregulatory functions remains elusive. Objective: It was shown
In this paper, an inventory model with finite and constant replenishment rate, price dependant demand rate, time value of money and inflation, finite time horizon, lead time and exponential deterioration rate and with the objective of maximizing the present worth of the total system profit is developed. Using a dynamic programming based solution algorithm, the optimal sequence of the cycles can be
Denna kandidatuppsats är en kvalitativ undersökning över hur länder i en rykteskris använder nationsvarumärkning och mjuk makt för att motverka negativa stereoty- per och förbättra sitt globala rykte. Nationsvarumärkning beskrivs som ett strate- giskt verktyg för att förbättra ett lands rykte och attraktivitet genom olika mark- nadsförings- och varumärkesmetoder. Flerstegsmodellen introduceras som
Sustainable energy storage and conversion utforskar innovativa metoder för att effektivt lagra och omvandla energi från olika förnybara källor. Fokus ligger på teknik som avancerade batterier, vätgasproduktion, bränsleceller och termokemiska system samt säkerhetsaspekter på batterilagringssystem. Forskningen syftar till att öka energitätheten, minska kostnaderna och förbättra skalbarheten, vilket

Introduction: Complicated perianal disease (cPD) may be the sole presentation of Crohn’s disease (CD). The role of small-bowel capsule endoscopy (SBCE) in the diagnostic algorithm of cPD is unclear. We aimed to evaluate the role of SBCE as a diagnostic tool, in patients with cPD, after a negative standard workup for CD. Methods: A multicenter, retrospective, cross-sectional study, in patients with
Aim: To investigate self-reported needs for care, support and treatment among persons who frequently visit psychiatric emergency rooms (PERs).Design: A cross-sectional design. Qualitative and quantitative data were collected using an interview-based manual. Qualitative data were analysed using content analysis, whereas quantitative data were analysed using descriptive, non-parametric statistical t
This paper examines the relationship between oil prices and its pass-through to inflation and inflation differentials in the European Monetary Union from the first quarter of 1999 to the last quarter of 2021. By using local projections to derive impulse response functions of an oil price shock, the pass-through to the inflation level is examined focusing on the role of energy-related transmission
Streptococcus bovis/Streptococcus equinus complex (SBSEC) is a common cause of infective endocarditis (IE). For IE-pathogens, the capacity to activate and aggregate platelets is believed to be an important virulence mechanism. While the interactions between bacteria and platelets have been described in detail for many Gram-positive pathogens, little research has been carried out with SBSEC in this
Housing expenditure is without doubt one of the biggest expenditure posts for all households. By using econometrics to estimate regressions with cross-‐sectional data including more than 1500 individuals, this thesis examines whether there is any individual characteristics that determines how big a share of the disposable income that is spent on housing each month. The results indicate that diffe

A trend, which can be noted in the field of cash handling, is the increase of ATMs that are able to recirculate banknotes. Cash recycling means that notes deposited by one customer are then available for withdrawal by another from the same machine. Cash recycling has both economic advantages and reduces environment impact, as transport to machines for filling and emptying them can be decreased. Wh
