On the spatial configuration of scatterers for given delay-angle distributions

2014

Published version of an article in the journal: Engineering Letters. Also available from the publisher at: http://www.engineeringletters.com/issues_v22/issue_1/EL_22_1_05.pdf. Open access This paper investigates the distribution of scatterers located around the mobile station (MS) for given delay-angle distributions. The delay-angle distribution function represents the joint probability density function (PDF) of the time-ofarrival (TOA) and angle-of-arrival (AOA). Given such a joint PDF, we first derive a general expression for the distribution of the scatterers in both polar and Cartesian coordinates. We then analyze an important special case in which the TOA and the AOA follow the multipl…

Spatial analysis of the Italian seismic network and seismicity

2018

Seismic networks are powerful tools for understanding active tectonic processes in a monitored region. Their numerous applications, from monitoring seismicity to characterizing seismogenic volumes and generated seismicity, make seismic networks essential tools for assessing seismic hazard in active regions. The ability to locate earthquakes hypocenters requires a seismic network with a sufficient number of optimally distributed, stations. It is important to assess existing network geometry, to identify seismogenic volumes that are not adequately monitored, and to quantify measures that will allow network improvement. In this work we have studied the spatial arrangement of the stations of th…

Integreating geological and seismological data in point process models for seismical analysis

2017

Nowadays in the seismic and geological fields, large and complex data sets are available. This information is a valuable source that can be used for improving the seismic hazard assessment of a given region. In particular, the integration of geologic variables into point process models to study seismic pattern is an open research field that has not been fully explored. In this work, we present several open-access datasets (the catalogue of the earthquakes, geological information such as faults, plate boundary and the presence of volcanoes) that are properly treated to describe the seismicity of events occurred in Greece between 2005 and 2014. We use these datasets to fit an advanced spatial…

The Influence of the Cross-Border Infrastructure Corridor on the Development of Medium-Sized Upper Silesian Cities on the Example of Bohumm and Jastr…

2018

The southern part of the A1 motorway (D1 in Czech designation) is a functioning infrastructure corridor connecting the Czech and Polish parts of the Upper Silesian Agglomeration, which is significant for the development of medium-sized cities in this region. This article is a continuation of research that was conducted in 2013. A research on Czech Bohumin and Polish Jastrzębie Zdrój was repeated with regard to the developmental aspects of these two medium-sized cities in the context of the functioning A1 motorway. The changes that have taken place in recent years in the spatial structure of the mentioned cities have been analysed. Research and analyses were conducted using ArcGIS software o…

Cel Osiągany w poszczególnych krajach i ich regionach poziom życia ludności w dużej mierze zależy od poziomu rozwoju społeczno-gospodarczego jaki prezentuje dane państwo. W przypadku większości krajów rozwiniętych i rozwijających się ogólny poziom życia społeczeństw ulega poprawie. Jednocześnie wzrasta dystans pomiędzy krajami i regionami o najniższym i najwyższym poziomie rozwoju społecznego. W Polsce m.in. ze względów kulturowych, historycznych, społecznych i ekonomicznych poziom życia ludności zamieszkującej różne regiony (województwa) jest odmienny. Polska, podobnie jak inne kraje członkowskie Unii Europejskiej (UE), podejmuje działania, których celem jest zniwelowanie różnic w poziomie…
