Two Relevant Forecasting Problems for Practitioners in Finance: Equity Risk Premium and Non-Performing Loans
2021
The thesis aims to substantiate whether macroeconomic factors indicators are relevant to predict both in-sample and out-of-sample assets' future performance focusing on two well-studied themes in financial economics and banking: First, the ability to predict the equity risk premium, and second, the macroeconomic determinants of non-performing loans (NPL) rates. The dissertation is divided in three chapters. Chapter 1, entitled "Forecasting the equity risk premium in the European Monetary Union", investigates the capacity of multiple economic and technical variables to predict the Euro area equity risk premium. The chapter examines the performance of several variables that could be good pred…
Regional economic structures in Finland : analyses of location and regional economic impact
2007
This dissertation consists of nine empirical studies which seek to broaden understanding of Finnish regional economic structures. These studies are divided between two topics: 1) regional specialization and industrial concentration in Finland, and 2) regional economic impact analysis. The empirical studies are preceded by an introduction, in which the theoretical background, outline and the main results of the thesis are presented. The research on the first topic is guided by the new economic geography literature, from which answers are sought to the location and agglomeration questions addressed in this dissertation. Evidence is found of increasing post-recession specialization in Finland.…
The Identification of Single Phase to Earth Faults in Overhead Lines of Electrical Power Distribution Systems
2005
Service continuity is one of the aspects of greater importance in the definition of the quality of electrical energy. After the electrical energy market liberalization, distributors have moved towards new investments in research, first of all in the field of faults diagnostic. The Authors have already studied the problem of the service continuity and this paper represents the development of the research carried out in the field. The paper presents the extension, to overhead distribution lines, of the new diagnostic approach to identify, locate and characterize the faulty events, made up by the Authors. The proposed methodology must be integrated in an electrical distribution networks manage…
Efficient finance regulator as supporter for financial stability of inhabitants
2020
Recent developments in banking sector in Latvia especially related with PNB Bank where bank accounts of many retired people were located leads to requirements for proficiency of Finance Regulator which has to be efficiently financed, stable and professional. In different countries Finance Regulators have different models of their financing. Aim of the study is to investigate different approaches for Finance Regulator financing and analyse expert views on possible development of Finance Regulator financing model in Latvia. Research methods applied: scientific publications and previous conducted research results analysis and expert survey for possible financing model changes in Latvia. In exp…
UAV-Aided Secure Short-Packet Data Collection and Transmission
2023
Benefiting from the deployment flexibility and the line-of-sight (LoS) channel conditions, unmanned aerial vehicle (UAV) has gained tremendous attention in data collection for wireless sensor networks. However, the high-quality air-ground channels also pose significant threats to the security of UAV aided wireless networks. In this paper, we propose a short-packet secure UAV-aided data collection and transmission scheme to guarantee the freshness and security of the transmission from the sensors to the remote ground base station (BS). First, during the data collection phase, the trajectory, the flight duration, and the user scheduling are jointly optimized with the objective of maximizing t…
On FE-grid relocation in solving unilateral boundary value problems by FEM
1992
We consider FE-grid optimization in elliptic unilateral boundary value problems. The criterion used in grid optimization is the total potential energy of the system. It is shown that minimization of this cost functional means a decrease of the discretization error or a better approximation of the unilateral boundary conditions, Design sensitivity analysis is given with respect to the movement of nodal points. Numerical results for the Dirichlet-Signorini problem for the Laplace equation and the plane elasticity problem with unilateral boundary conditions are given. In plane elasticity we consider problems with and without friction. peerReviewed
Selected methods of location logistic distribution centers in food supply chains
2020
W pracy przedstawiono jedną z wielu prezentowanych w literaturze przedmiotu metodę wyboru lokalizacji logistycznego centrum dystrybucyjnego w łańcuchach dostaw żywności. Metoda ta rozpatruje problem wyboru lokalizacji w aspekcie kosztów całkowitych lub czynnika przestrzeni, a dokładniej – odległości. W pracy przedstawiono możliwość zastosowania tej metody. W tym celu przedstawiono krótki przegląd literatury, następnie na końcu artykułu pokazano możliwość zastosowania metody do rozwiązania problemu.
Karyotype dispersal of the common lizard Zootoca vivipara (Lichtenstein, 1823) in eastern and northeastern Fennoscandia
2015
The wide-ranging Eurasian common lizard Zootoca vivipara (Lichtenstein, 1823) is remarkably uniform morphologically but highly varied in its karyotype. Previous studies have revealed two distinctly different chromosomal forms of Z. v. vivipara in the Baltic basin. Moreover, a zone of secondary contact between these forms has been localized on the southern Baltic Sea seashore. Intraspecific karyotype diversity for Z. vivipara and new zones of secondary contact have recently been suggested for other parts of the Baltic Sea seashore. We studied the karyotype of Z. vivipara in central, western and northern parts of Finland. All the individuals karyotyped represented the Russian form of Z. v. vi…
Theoretical Game Approach for Mobile Users Resource Management in a Vehicular Fog Computing Environment
2018
Vehicular Cloud Computing (VCC) is envisioned as a promising approach to increase computation capabilities of vehicle devices for emerging resource-hungry mobile applications. In this paper, we introduce the new concept of Vehicular Fog Computing (VFC). The Fog Computing (FC) paradigm evolved and is employed to enhance the quality of cloud computing services by extending it to the edge of the network using one or more collaborative end-user clients or near-user edge devices. The VFC is similar to the VCC concept but uses vehicles resources located at the edge of the network in order to serve only local on-demand mobile applications. The aim of this paper is to resolve the problem of admissi…
A non-cooperative approach to the folk rule in minimum cost spanning tree problems
2023
This paper deals with the problem of finding a way to distribute the cost of a minimum cost spanning tree problem between the players. A rule that assigns a payoff to each player provides this distribution. An optimistic point of view is considered to devise a cooperative game. Following this optimistic approach, a sequential game provides this construction to define the action sets of the players. The main result states the existence of a unique cost allocation in subgame perfect equilibria. This cost allocation matches the one suggested by the folk rule.
