A combined approach for multi-label text data classification
(Computational intelligence and neuroscience, 2022)Automated data analysis solutions are very dependent on data and its quality. The possibility of assigning more than one class to the same data item is one of the specificities that need to be taken into account. There are ... -
Analyses of archival cartographic materials for geomorphological changes of river channel
(Advances in civil engineering, 2018)In Lithuania, the old archival topographic maps of locations of small and medium scale and 1 : 10,000 scale contour photo plans were created on the basis of aerial images. The material of these scales provides documented ... -
Assesment of tritium activity in groundwater at the nuclear objects sites in Lithuania
(International Journal of Nuclear Energy, 2014)The assessment of nuclear objects sites in Lithuania, including groundwater characterization, took place in the last few years. Tritium activity in groundwater is a very useful tool for determining how groundwater systems ... -
Automatic control of loading forces in a tilting pad journal bearing
(Advances in mechanical engineering, 2014)Hydrodynamic three-tilting-pad journal bearing is analyzed. It is shown that a carrying force, stiffness of the bearing, and heat generated at journal rotation highly depend on a clearance between the journal and pads. The ... -
Building Information Modeling (BIM) for structural engineering: a bibliometric analysis of the literature
(Advances in civil engineering, 2019)Building information modeling (BIM) is transforming the way of work across the architecture, engineering, and construction (AEC) industry, where BIM offers vast opportunities for improving performance. BIM is therefore an ... -
Crack width and load-carrying capacity of RC elements strengthened with FRP
(International journal of polymer science, 2018)The present study focuses on a prediction of crack width and load-carrying capacity of flexural reinforced concrete (RC) elements strengthened with fibre-reinforced polymer (FRP) reinforcements. Most studies on cracking ... -

Distribution of peripheral lymphocyte populations in primary Sjögren’s syndrome patients
(Journal of immunology research, 2015)Purpose of this study was to evaluate the lymphocyte populations’ distribution changes in peripheral blood of patients with primary Sjogren’s syndrome (pSS). Lymphocyte populations’ distribution changes in peripheral blood ... -
Evaluation of deep learning methods efficiency for malicious and benign system calls classification on the AWSCTD
(Security and communication networks, 2019)The increasing amount of malware and cyberattacks on a host level increases the need for a reliable anomaly-based host IDS (HIDS) that would be able to deal with zero-day attacks and would ensure low false alarm rate (FAR), ... -
Experimental and analytical investigation of deformations and stress distribution in steel bands of a two-span stress-ribbon pedestrian bridge
(Mathematical problems in engineering, 2017)The article is dedicated to the analysis of problems related to design of pedestrian bridges with flexible ribbon bands made of steel. The study is based on test results of a bridge model that has two spans (each with a ... -
Experimental investigation of tension stiffening in RC ties
(Advances in materials science and engineering, 2016)The increasing application of high-performance materials in civil engineering led to the development of reinforced concrete (RC) structures with reduced cross sections and increased spans. In such structures serviceability ... -
