Varieties Generated by Certain Models of Reversible Finite Automata

2006

Reversible finite automata with halting states (RFA) were first considered by Ambainis and Freivalds to facilitate the research of Kondacs-Watrous quantum finite automata. In this paper we consider some of the algebraic properties of RFA, namely the varieties these automata generate. Consequently, we obtain a characterization of the boolean closure of the classes of languages recognized by these models.

Modified total variation regularization using fuzzy complement for image denoising

2015

In this paper, we propose a denoising algorithm based on the Total Variation (TV) model. Specifically, we associate to the regularization term of the Rodin-Osher-Fatimi (ROF) functional a small weight whenever denoising is performed in edge and texture regions, which means less regularization and more details preservation. On the other hand, a large weight is associated if the region being filtered is smooth which means noise will be well suppressed. The weight computation is inspired from the fuzzy edge complement. Experiments on well-known images and comparison with state of the art denoising algorithms demonstrate that the proposed method not only presents good denoising performance but …

Visual attention while solving the test of understanding graphs in kinematics: an eye-tracking analysis

2019

This study used eye-tracking to capture students' visual attention while taking a test of understanding graphs in kinematics (TUG-K). A total of N = 115 upper-secondary-level students from Germany and Switzerland took the 26-item multiple-choice instrument after learning about kinematics graphs in the regular classroom. Besides choosing the correct alternative among research-based distractors, the students were required to judge their response confidence for each question. The items were presented sequentially on a computer screen equipped with a remote eye tracker, resulting in a set of approx. 3000 paired responses (accuracy and confidence) and about 40 h of eye-movement data (approx. 500…

Regularisaatio vahvojen gravitaatiolinssien inversiossa

2015

Massiivisten galaksien gravitaatio aiheuttaa vääristymän teleskoopilla havaittavaan kuvaan muuttamalla galaksin takaa saapuvan valon reittiä. Niin kutsu- tuissa vahvoissa gravitaatiolinsseissä voi linssinä toimiva galaksi tuottaa kuvaan sen takana olevasta galaksista useita näyttäviä kaaria. Linssinä toimineen galaksin massa ja linssiytyneen galaksin alkuperäinen muoto voidaan tällöin laskennallisesti selvit- tää, ja näin saada tietoa linssigalaksin massan ja teleskoopilla suoraan havaitun valon määrän suhteesta. Tämän lähtökohtaisesti huonosti määritellyn inversio-ongelman laskennallinen ratkaiseminen vaatii kuitenkin ongelman uudelleenmäärittelyä eli regularisaatiota. Ongelman ratkaisemis…

INTERNAL AUDIT: DEFINING, OBJECTIVES, FUNCTIONS AND STAGES

2010

This article aims, through a detailed presentation as to provide clarification for a better understanding of what internal audit definition, objectives, functions and stages of its development mean. It is also exposed a brief history about the emergence and development of internal audit and regulatory framework. I also plan to linking theory and practice by reference to documents used: both the evidence considered and especially those prepared by the auditors in connection with the performance audit and its use in the audit report.

ON SOME GENERALIZATION OF SMOOTHING PROBLEMS

2015

The paper deals with the generalized smoothing problem in abstract Hilbert spaces. This generalized problem involves particular cases such as the interpolating problem, the smoothing problem with weights, the smoothing problem with obstacles, the problem on splines in convex sets and others. The theorem on the existence and characterization of a solution of the generalized problem is proved. It is shown how the theorem gives already known theorems in special cases as well as some new results.

Kontaktlēcu ietekme uz redzes asumu pacientiem ar neregulāru radzeni

2017

Darbs uzrakstīts angļu valodā uz 39 lapām. Tas satur 11 attēlus, 1 aptaujas lapu, 11 tabulas and 24 atsauces uz literatūras avotiem. Mērķis: darba galvenais mērķis ir salīdzināt parastās gāzu caurlaidīgās kontaktlēcas ar gāzu caurlaidīgajām intralimbālajām lēcām. Metodes: gāzu caurlaidīgās intralimbālās lēcas tika novērtētas, pētījuma dalībniekiem aizpildot anketu. Rezultāti: pētījuma dalībnieki deva priekšroku gāzu caurlaidīgajām intralimbālajām lēcām un novērtēja to sniegto komfortu, tomēr nebija būtiskas atšķirības starp iegūto redzes asumu abu lēcu gadījumā. Secinājumi: izvērtējot katra pacienta individuālo sutāciju, optometrists var apsvērt intralimbālo lēcu izrakstīšanu pecientam, lai…

The market of migrant smuggling through Libya to Southern Italy since 2011: filling the knowledge gap as a human rights' strategy

2018

The first formal distinction between human smuggling and trafficking in international law was made with the signing in December 2000 of the Palermo Protocols. These definitions have influenced and shaped most of the academic research, discourse, methodology and language on human smuggling and trafficking. In turn, an understanding of the formal definitions of these crimes is necessary to appreciate their influence on policies and therefore their effects on the individuals and institutions involved (Campana and Varese, 2015). The argument at the basis of this thesis is that academic research on especially migrant smuggling has often blindly adopted the above-mentioned definitions as a given-…

Latvijas armijas neregulārās karaspēka vienības Neatkarības kara laikā 1919.-1920.gadā

2020

Bakalaura darba mērķis ir izpētīt neregulārā karaspēka vienību jeb partizānu vienību un pulku darbību Neatkarības kara laikā, no 1919. gada marta līdz 1920. gadam janvārim. Partizāni sagādāja ievērojamas problēmas Padomju varas orgāniem Vidzemē, Ziemeļlatgalē un Augškurzemē, kas bija veicinošs iemesls Padomju varas sagrāvei, kā arī piedalījās austrumu frontes nostiprināšanā pēc Padomju varas atkāpšanās uz Latgali. Darbā galvenā uzmanība tiek vērsta uz vienību specifisko izveidošanos un sastāvu. Darbs ir sadalīts četrās nodaļās, kur pirmajā nodaļā tiek aplūkoti centrālie militārie procesi, un pārējās trīs nodaļas ir iedalītas attiecīgi pēc partizānu vienību un pulku atrašanās vietas, tas ir,…
