    Title: Performing track reconstruction at the ALICE TPC using a fast Hough Transform method
    Author: Kouzinopoulos, Charalampos; Hristov, Peter
    Subject: ALICE ; Track Reconstruction ; TPC ; Hough transform
    Description: The Hough Transform algorithm is a popular image analysis method that is widely used to perform global pattern recognition in images through the identification of local patterns in a suitably chosen parameter space. The algorithm can also be used to perform track reconstruction; to estimate the trajectory of individual particles when passed through the active elements of a detector volume. This paper presents a fast reconstruction method for the Time Projection Chamber (TPC) of the ALICE experiment at LHC. The method, that combines a linear Hough Transform algorithm with a fast filling of the Hough Transform parameter space, is developed within AliceO 2 , the new computing framework of ALICE for RUN3.

    Title: Numerical modelling and uncertainty quantification of biodiesel filters
    Author: Hristov, Peter O
    Publisher: University of Liverpool
    Date: 2018
    Description: This dissertation explores the design and analysis of computer models for filters used to separate water from biodiesel. Regulations concerning air pollution and increasing fossil fuel scarcity mandate the transition towards biofuels. Moreover, increasingly stringent standards for fuel cleanliness are introduced continually. Biodiesel exhibits strong affinity towards water, which makes its separation from the fuel challenging. Water in the fuel can cause problems, ranging from reduced performance to significant damage to the equipment. A model of the filter is needed to substitute costly or impractical laboratory experiments and to enable the systematic studies of coalescence processes. These computational experiments provide a means for designing filtration equipment with optimal separation efficiency and pressure drop. The coalescence process is simulated using the lattice Boltzmann modelling framework. These models offer several advantages over conventional computational fluid...

    Title: Mitochondrial diversity of Bulgarian native dogs suggests dual phylogenetic origin
    Author: Marinov, Miroslav; Teofanova, Denitsa; Radoslavov, Georgi; Hristov, Peter
    Subject: Bulgaria ; Phylogenetics ; Investigations ; Mitochondria ; Phylogeny ; Hunting ; Dogs ; Bulgarian Native Dog ; D-Loop Region ; Genetic Diversity ; Population Structure
    Description: The dog has been the first domesticated animal to have a central role in human society from ancient times to present day. Although there have been numerous investigations of dog phylogeny and origin, genetic data of dogs in the region of the Balkan Peninsula (South-Eastern Europe) are still scarce. Therefore, the aim of the present study has been to perform phylogenetic analysis of three native Bulgarian dog breeds. A total of 130 samples were analyzed according to HVR1 (hypervariable region, D-loop region). The samples were taken from two hunting dog breeds (Bulgarian Hound dog: Barak, n=34; Bulgarian Scenthound dog: Gonche, n=45) as well as from a Bulgarian Shepherd dog (n=51). The first two breeds are reared in a flat region of the country (the Northern part of Bulgaria, the Danubian Plain), while the last breed is a typical representative of the mountainous part of the country. The results have shown the presence of almost all main clades – A, B, C and D – in the three dog breeds taken...
