This study comprehensively analyzes time series momentum and moving average strategies for the Korean stock market. The results of the empirical analysis are as follows. The correlation coefficients between the returns of time series momentum and moving average strategies are on average above 0.8, indicating that the two strategies are closely related. When calculating risk-adjusted returns and abnormal returns, Sharpe ratios and Jensen alphas were generally higher for the moving average strategy compared to the time series momentum strategy.

This thesis examines the performance of the trend-following strategies known as absolute momentum strategies. In particular, I will examine the “Times-series momentum” strategy. First, I will investigate, analyzing different asset classes, if this strategy is still persistent in today’s market. Second, the portfolio strategy will be tested looking at different lookback periods and testing for different predictability horizons in order to investigate if there is a different and time-varying predictability horizon across the asset classes.

Abstract:
This study investigates if momentum effects can be found on the Swedish stock market by testing a cross-sectional momentum strategy on historical data. To explain the results mathematically, a second approach, involving time series regression for predicting future returns is introduced and thereby extends the cross-sectional theory. The result of the study shows that momentum effects through the cross-sectional strategy exist on the Swedish stock market. Although positive return is found, the time series regression do not give any significance for predicting future returns. Hence, there is a c

Abstract:
In time series models, autoregressive processes are one of the most popular stochastic processes, which are stationary under certain conditions. In this study we consider nonstationary autoregressive models of order one, which have iid random errors. One of the important nonstationary time series models is the unit root process in AR (1), which simply implies that a shock to the system has permanent effect through time. Therefore, testing unit root is a very important problem. However, under nonstationarity, any estimator of the autoregressive coefficient does not have a known exact distribut

The first is when Niebuhr abandons love as an ordering principle. The second is when Niebuhr articulated the “moment of anxiety,”

Meso-scale motion is obtained by changing the voltage of electrodes rapidly over time to create a nearly continuous force on the ions.

The outbreak of the COVID-19 pandemic was an unprecedented event in the modern era. Earlier studies demonstrated how ‘critical junctures’, which comprise major historical events and emergencies, often play an essential role in social change. This paper seeks to explore whether the COVID-19 pandemic would prove to be a similar pivotal moment, and what lessons and insights we could gather for positive social change. The research set out to find key insights on how individuals, communities, and organizations in civil society were responding to the pandemic in low-income populations at the interse

Abstract:
This document describes the industrial application, on which the developments of the project are implemented, and the CFD set-up. The developments are implemented over six analysis cases with increasing complexity starting from a 2D geometry with mean wind inflow to a 3D geometry with turbulent inflow and real-time shape optimization. The application represents the CAARC tall building model, which has served as a benchmark model for many studies since the 1970’s when it was first developed. Base moments (bending and torsional moments) of the building are extracted for validation by comparison

Abstract:
The article analyzes the concepts of "good" and "evil" from the point of view of physics. Although the physical concept of “entropy” as a measure of disorder was the first candidate who could serve as the physical basis of these ethical concepts, in fact it is not suitable for this purpose. However, the “entropic potential of the event” Z (T, A) that describes the impact of the event A that occurred in the moment T0 in the system R to the entropy of this system at the future moment T (T &gt; T0) is well suited for our analysis. The article describes methods for calculating the “entropic potent

Abstract:
In the decade after the Civil Rights Act of 1964, African Americans made historic gains in accessing employment opportunities in racially integrated workplaces in U.S. business firms and government agencies. In the previous working papers in this series, we have shown that in the 1960s and 1970s, Blacks without college degrees were gaining access to the American middle class by moving into well-paid unionized jobs in capital-intensive mass production industries. At that time, major U.S. companies paid these blue-collar workers middle-class wages, offered stable employment, and provided employe

Abstract:
The theory of near-surface atmospheric wind noise is largely predicated on assuming turbulence is homogeneous and isotropic. For high turbulent wavenumbers, this is a fairly reasonable approximation, though it can introduce non-negligible errors in shear flows. Recent near-surface measurements of atmospheric turbulence suggest that anisotropic turbulence can be adequately modeled by rapid-distortion theory (RDT), which can serve as a natural extension of wind noise theory. Here, a solution for the RDT equations of unidirectional plane shearing of homogeneous turbulence is reproduced. It is ass
