The thesis describes design, algorithmization and realization of graphical application for recording EKG and PPG signal using LabJack UE9 tool in Matlab program, it also describes subsequent deposition of recorded signals and their processing, such as optional selection, cropping and filtering. Furthermore there are described types of filters, methods for detecting basic parameters of EKG and PPG signals and methods for detecting R waves and Systolic peaks. Based on detection of those parameters, algorithms for computing average heart rate and finding arrhythmias were designed and tested. Last part of the thesis includes an evaulation which compares values detected by designed algorithms with values from public database which includes reference annotation.

Second part of the work is focused on the measurement itself and data analysis. The last part of the work consists of comparison of calculated parking places according to standards with real number of parking places.

In this thesis, we consider the pricing problem of an American put option. We introduce a new market model for the evolution of the underlying asset price. Our model adds a new parameter to the well known Heston model. Hence we name our model the extended Heston model. To solve the American put pricing problem we adapt the idea developed by Fouque et al. (2000) to derive the asymptotic formula. We then connect the idea developed by Medvedev and Scaillet (2010) to provide an asymptotic solution for the leading order term P0. We do numerical analysis to gain insight into the accuracy and validity of our asymptotic approximation formula.

2,4,6-Trinitrotoluene, TNT, is an explosive used in munitions production that is known to cause both aplastic and hemolytic anemia in exposed workers. Deaths have been reported secondary to both varieties of anemia. Studies have shown that TNT systemic absorption is significant by both the respiratory and dermal routes. A literature review revealed that the most recent review article on TNT exposure arguing for a TWA drop from the PEL to the TLV was in 1977 -- this article cited anemia issues in addition to other untoward effects of TNT. No studies encountered looked at hemoglobin change or anemia cases in respiratory protected workers, this present effort may be the first. TNT PEL (1.5mg/m^3), REL (0.5mg/m^3), and TLV (0.1 mg/m^3) 8 hr TWAs all with skin notations (based on animal models and TNT urine metabolite extrapolation in TNT workers suggesting important role of skin absorption). The earliest effects of systemic TNT poisoning involve hgb and hematocrit drop. The investigator hypothesized that respiratory protection alone is insufficient to protect TNT workers from the risk of anemia development and hemoglobin concentration drop. A retrospective observational study design was incorporated utilizing a records review of TNT vapor air concentration values and worker Hgb values for 8 sets of workers in respiratory protection at a demilitarization operation from October 2006 to April 2007 in order to observe whether or not respiratory protection provided adequate protection against anemia development and hemoglobin change; and to help characterize the probable role of TNT skin absorption on hemoglobin change and anemia risk. Worker baseline hgbs were compared with their exposure hgbs for statistically significant hgb concentration changes (two-tailed paired t-tests), and anemia cases were recorded. Mean hgb changes within each of the 8 groups of workers were then regressed on mean TNT air concentrations (10 hr TWAs) using air sampling levels that were performed closest in time to exposure hgbs. Statistically significant hgb concentration drops and anemia cases were apparent at values about the REL and PEL in respiratory protected workers. There were no anemia cases or statistically significant hgb drops at values about the TLV, however. For mean TNT air concentrations from 0.12/m 3 to 0.31/m 3 there was strong positive linear association with regard to magnitude of hgb change (r=0.996). The results appear to confirm the necessity of the skin notation for TNT. However, the TLV seems to be protective against the possibility of anemia risk principally by the dermal route in workers who are respiratory protected. A question does still remain, however, as to anemia risk in workers who are below the TLV who may not be using respiratory protection. The absence of a continued linear association between mean TNT air concentrations and mean hgb change above the 0.31 mg/m 3 TNT level most likely reflects a marrow response, as the TNT levels evident in the study are reported to be mainly associated with extravascular hemolysis with a minimal, or non-existent, aplastic component assumed. This study adds evidence to the argument that the TLV should be adopted as the new PEL.

The paper considers approximations of time-continuous epsilon-correlated random processes by interpolation of time-discrete Moving-Average processes. These approximations are helpful for Monte-Carlo simulations of the response of systems containing random parameters described by epsilon-correlated processes. The paper focuses on the approximation of stationary epsilon-correlated processes with a prescribed correlation function. Numerical results are presented.

In dieser Arbeit werden stochastische Charakteristiken der Lösung parabolischer Differentialgleichungen mit zufälligen Neumann-Randbedingungen mit Hilfe der Finite-Elemente-Methode angegeben. Dabei wird der Berechnung der Korrelations- bzw. Varianzfunktion besondere Bedeutung beigemessen. Das stochastische Randanfangswertproblem wird durch Anwendung von FEM-Techniken durch ein System gewöhnlicher Differentialgleichungen mit stochastischen inhomogenen Termen approximiert. Die Modellierung der stochastischen Eingangsparameter durch epsilon-korrelierte Felder gestattet Entwicklungen der Lösungscharakteristiken nach der Korrelationslänge. Numerische Beispiele enthalten den Vergleich zwischen analytischen Ergebnissen und Simulationsresultaten.

Background: Denmark, along with other European countries, has decided to cut its policy interest rate into negative territory to meet macroeconomic objectives. This has historically been thought of as impossible and impacts commercial banks significantly. As a consequence, concerns have been raised about commercial bank profitability, which is a primary indicator of the banking industry’s soundness. Purpose: The purpose of this thesis is to investigate the relationship between persistently negative interest rates and commercial bank profitability in Denmark, covering an extended timeframe (2011 – 2018, 165 bank years, 21 commercial banks). Method: Bank profitability is measured using the Return on Average Assets (ROAA) and the Net Interest Margin (NIM). The thesis follows a simple form of mixed-methods approach –quantitatively focused, followed by a supplementary qualitative study. For the quantitative part, data is collected through the Orbis database, which provides global company data. We utilized a Fixed Effects Model with strongly balanced panel data, covering 59% of the Danish banking industry’s assets. Semi-structured interviews were then conducted with professionals working in the industry to interpret the quantitative findings. Conclusion: The findings of this study show that in the time period observed: Interest rates are not correlated with the NIM; The duration of consecutive negative interest rates (in years) is negatively correlated with the NIM; Interest rates are not correlated with the ROAA; The duration of consecutive negative interest rates (in years) is not correlated with the ROAA; The duration of consecutive negative interest rates seems to be more significant since it takes time for the profitability-reducing effect of negative interest rates to materialize. The ROAA is not impacted by the (years in negative) interest rates, as it is mainly determined by factors under management control.

För att beslutsfattare och dagligvaruaktörer ska kunna fatta välgrundade beslut vid etablering av nya butiker är det viktigt att känna till hur demografiska faktorer påverkar dagligvarumarknaden. I denna uppsats analyserar vi med data för 2016 hur demografiska faktorer påverkar förekomsten av olika butikssegment på lokala marknader i Sverige samt hur demografi påverkar butikssegmentens omsättningsandelar. Segmenten skapades inom ramen för uppsatsen baserat på tidigare forskning och dagligvaruaktörernas egna butiksdefinitioner. Med logistiska regressioner på stadsdelsnivå finner vi (i) att en ökande andel befolkning med utrikes bakgrund påverkar sannolikheten positivt att minst en lågprisbutik finns etablerad i ett område, men påverkar sannolikheten att minst en traditionell mindre butik finns etablerad negativt. Vidare, med hjälp av OLS-regressioner på stadsdelsnivå finner vi (ii) att en högre andel befolkning med utrikes bakgrund påverkar lågprisbutikers andel av ett områdes totala omsättning positivt, men påverkar traditionella mindre butikers andel negativt. Till sist, indikerar resultatet (iii) att framförallt flödet av människor påverkar traditionella större butiker, både dess geografiska plats samt deras andel av ett områdes totala omsättning. På kommunnivå visar OLS-regressionerna delvis otydliga resultat, förmodligen till följd av allt för aggregerad data. Vår studie bidrar till den existerande litteraturen genom att analysera butiksetableringar och demografi i en svensk kontext. Tidigare forskning har främst undersökt den amerikanska och olika europeiska marknader. / It is important for policy makers and retail chains to recognise how demographics affect the non- durable goods business in order to make qualified decisions about establishing new grocery stores. In this thesis, using data from 2016, we analyse how demographics affect the presence of different store segments at local markets in Sweden and how it affects the turnover share of different store segments. The segments were defined as a part of this thesis and are based on previous literature and the concept description made by each included company. Using logit regressions on urban districts, we find (i) that a larger share of population with foreign background increases the probability that at least one discount store is established in the district but decreases the probability that at least one traditional small store is established. Further, using an OLS-regression on urban districts we find (ii) that a larger share of population with foreign background increases the share of total turnover in discount stores and decreases the share of total turnover for traditional small stores. Finally, our result indicates (iii) that the flow of people significantly affects traditional large stores, both regarding their presence on local markets as well as their share of the total turnover. When using municipalities as local markets, our OLS-regression provides partly indefinite results, probably a consequence of the aggregated data. Our thesis contributes to the existent literature by analysing store establishment and demography in a Swedish context. Previous literature has mainly evaluated American and European markets.

Vasaloppet is a cross country ski event which has been held in Sweden for about 50 years. Now more than 50,000 people of different ages participate in various cross country ski races during the Vasaloppet winter week in Dalarna County. This increasing demand needs good traffic and transportation planning to avoid congestion and provide safe, on time and environmentally friendly transportation for participants and visitors to the area. The key for a good event traffic planning is reliable and up-to-date traffic data which is not available for the Vasaloppet winter week. This study is an attempt to collect traffic data in order to find the movement patterns in the area and estimate origin-destination matrices for the main event of Vasaloppet week. Based on resources and time limitation it was decided to use a web-base d participants’ survey in order to collect traffic data. The link to the survey was sent to email address of a sample of 5000 participants. About 64% of the participants drove from their home town to the area and about 31 percent travelled by bus. Train and airplane have a very small share in travel mode to the area. Malungsälen, Mora and Älvdalen are three municipalities in Dalarna County with the highest share in accommodating participants. On the day of the race, bus and car have approximately the same share in travel mode with 45% and 47% respectively.
