2015
Kvalifikācijas darbā „Tēzaurs.lv tīmekļa saskarne, izmantojot dokumentoriantētu datu bāzi” aprakstīta jauna tīmekļa saskarnes izveide lielākajai tiešsaistē pieejamai latviešu valodas skaidrojošajai vārdnīcai (243 tūkst. šķirkļu). Izveidotais programmprodukts nodrošina saskarni šīs vārdnīcas šķirkļu meklēšanai, apskatīšanai un rediģēšanai, kā arī vārdnīcā neietilpstošu automātiski ģenerētu papildu datu attēlošanu. Darba ietvaros veikta saskarnes prasību apzināšana, programmprodukta projektāšana, realizēšana, izmantojot programmēšanas valodu Python, ietvaru Django un dokumentorientētu datubāzu dzinēju MongoDB, kā arī radīta produkta kvalitātes nodrošināšana, ieskaitot testēšanu.
WCxf: An exchange format for Wilson coefficients beyond the Standard Model
2018
We define a data exchange format for numerical values of Wilson coefficients of local operators parameterising low-energy effects of physics beyond the Standard Model. The format facilitates interfacing model-specific Wilson coefficient calculators, renormalisation group (RG) runners, and observable calculators. It is designed to be unambiguous (defining a non-redundant set of operators with fixed normalisation in each basis), extensible (allowing the addition of new EFTs or bases by the user), and robust (being based on industry standard file formats with parsers implemented in many programming languages). We have implemented the format for the Standard Model EFT (SMEFT) and for the weak e…
Sociālā tīkla Twitter datu korpusa izveide laikā segmentētu emociju kopu analīzei
2021
Bakalaura darba mērķis ir izpētīt emociju lietojumu sociālajā tīklā Twitter dažādos laika posmos un noteikt kā paustās emocijas mainās, piemēram, diennakts laikā. Mērķa sasniegšanai tiks apskatīta emociju pētniecības sociālajos tīklos, tās nepieciešamība un priekšrocības, tiks apskatīta emociju sistēma no kuras tiks izvēlēti pētījumā izmantotie emocijvārdi. Tiks izveidots Twitter datu analizēšanas korpuss, izmantojot Python programmēšanas valodu, kurā būs iespējams atlasīt Twitter ierakstus latviešu valodā pēc noteiktiem parametriem un iespēja apskatīt dažādas diagrammas, kurās tiks attēloti atlasītie dati, kā arī būs iespējams apskatīties atlasītos ierakstus tabulā. Darba rezultātā tiks iz…
Towards a cyber-physical era: soft computing framework based multi-sensor array for water quality monitoring
2018
Abstract. New concepts and techniques are replacing traditional methods of water quality parameter measurement systems. This paper introduces a cyber-physical system (CPS) approach for water quality assessment in a distribution network. Cyber-physical systems with embedded sensors, processors and actuators can be designed to sense and interact with the water environment. The proposed CPS is comprised of sensing framework integrated with five different water quality parameter sensor nodes and soft computing framework for computational modelling. Soft computing framework utilizes the applications of Python for user interface and fuzzy sciences for decision making. Introduction of multiple sen…
Fault diagnosis and modeling of the liquids packaging process. A research based on Petri Nets
2008
Searching for solutions to manufacture industries, which every day deal with problems of faults in their process, that generate economics and humans main losses, an algorithm to construct a Petri Nets based model and diagnoser to isolate and fault detection of discrete events systems is presented. This algorithm is developed in a real process of liquids packaging, where we can see that its implementation allows detecting individuals, simultaneous and dependents faults. The process to construct the model and diagnoser is systematic and useful, and it reduces the problems of combinational explosion, which is the main problem present in other investigations. This research has an excellent proj…

Array programming with NumPy.
2020
Array programming provides a powerful, compact and expressive syntax for accessing, manipulating and operating on data in vectors, matrices and higher-dimensional arrays. NumPy is the primary array programming library for the Python language. It has an essential role in research analysis pipelines in fields as diverse as physics, chemistry, astronomy, geoscience, biology, psychology, materials science, engineering, finance and economics. For example, in astronomy, NumPy was an important part of the software stack used in the discovery of gravitational waves1 and in the first imaging of a black hole2. Here we review how a few fundamental array concepts lead to a simple and powerful programmi…
A novel approach to integration by parts reduction
2015
Integration by parts reduction is a standard component of most modern multi-loop calculations in quantum field theory. We present a novel strategy constructed to overcome the limitations of currently available reduction programs based on Laporta's algorithm. The key idea is to construct algebraic identities from numerical samples obtained from reductions over finite fields. We expect the method to be highly amenable to parallelization, show a low memory footprint during the reduction step, and allow for significantly better run-times.
A comprehensive study of automatic program repair on the QuixBugs benchmark
2021
Abstract Automatic program repair papers tend to repeatedly use the same benchmarks. This poses a threat to the external validity of the findings of the program repair research community. In this paper, we perform an empirical study of automatic repair on a benchmark of bugs called QuixBugs, which has been little studied. In this paper, (1) We report on the characteristics of QuixBugs; (2) We study the effectiveness of 10 program repair tools on it; (3) We apply three patch correctness assessment techniques to comprehensively study the presence of overfitting patches in QuixBugs. Our key results are: (1) 16/40 buggy programs in QuixBugs can be repaired with at least a test suite adequate pa…
Corrigendum: ExGUtils: A Python Package for Statistical Analysis With the ex-Gaussian Probability Density
2018
The study of reaction times and their underlying cognitive processes is an important field in Psychology. Reaction times are usually modeled through the ex-Gaussian distribution, because it provides a good fit to multiple empirical data. The complexity of this distribution makes the use of computational tools an essential element in the field. Therefore, there is a strong need for efficient and versatile computational tools for the research in this area. In this manuscript we discuss some mathematical details of the ex-Gaussian distribution and apply the ExGUtils package, a set of functions and numerical tools, programmed for python, developed for numerical analysis of data involving the ex…
