Automated Railway Signs Detection. Preliminary Results

2019

Abstract Nowadays safety in railways is mostly achieved by automated system technologies such as ERTMS/ETCS. Nevertheless, on local railways (suburban and regional lines) several tasks still depend on the choices and actions of a human crew. With the aim to improve safety in such type of railways, this research proposes a system for the automatic detection and recognition of railway signs by means of the digital image processing technique. First field applications, carried out on the Italian railway network, show that the proposed system is very accurate (the percentage of correctly detected railway signs is about 97%), even at high train speeds.

Criminal proceedings in written procedure during restrictions on the spread of Covid-19

2022

Lai mazinātu tiesu noslodzi un lietu izskatīšanas termiņus, likumdevējs Kriminālprocesa likumā ir noteicis gadījumus, kad tiesas var pieņemt lēmumu par lietas izskatīšanu rakstveida procesā. Tomēr laikā, kad valstī ar vien vairāk sāka izplatīties Covid-19 infekcija, likumdevējam nācās noteikt papildus gadījumus, kad tiesas var lemt par lietas izskatīšanu rakstveidā. Tāpēc darba izstrādes mērķis ir noskaidrot, kādus papildus gadījumus, kad lietu ir iespējams izskatīt rakstviedā, likumdevējs ir noteicis speciālajos noteikumos, vai šie noteikumi ietekmē personas tiesības uz lietas izskatīšanu mutvārdu procesā, kā arī, vai Kriminālprocesa likumā būtu pieļaujams veikt grozījumus un iekļaut speci…

Kriminālprocesu nepieļaujošie apstākļi

2022

Pēdējo reizi Kriminālprocesa likuma 377. pants tika grozīts 2016. gadā, kopš tā laika ir veikti vairāki grozījumi citos normatīvajos aktos, kas maina izpratni par piemērojamo institūtu. Pētījuma mērķis ir izpētīt kriminālprocesu nepieļaujošo apstākļu interpretāciju un to piemērošanu praksē. Bakalaura darba galvenie uzdevumi ir apzināt kriminālprocesu nepieļaujošo apstākļu vesturisko attīstību, tiesisko regulējumu, judikatūru, saistīto literatūru, statistikas datus un veikt tās izpēti un analīzi, kā arī apzināt problemātiku. Darba autore konstatēja, ka Kriminālprocesa likuma 377.pantā būtu nepieciešams veikt vairākus grozījumus, kas saistīti ar dažādu terminoloģijas lietošanu, pētāmā institū…

Disrupted Spatial Organization of Cued Exogenous Attention Persists Into Adulthood in Developmental Dyslexia

2021

Purpose: Abnormal exogenous attention orienting and diffused spatial distribution of attention have been associated with reading impairment in children with developmental dyslexia. However, studies in adults have failed to replicate such relationships. The goal of the present study was to address this issue by assessing exogenous visual attention and its peripheral spatial distribution in adults with developmental dyslexia.Methods: We measured response times, accuracy and eye movements of 18 dyslexics and 19 typical readers in a cued discrimination paradigm, in which stimuli were presented at different peripheral eccentricities.Results: Results showed that adults with developmental dyslexia…

Proteins in Ionic Liquids: Reactions, Applications, and Futures

2019

Biopolymer processing and handling is greatly facilitated by the use of ionic liquids, given the increased solubility, and in some cases, structural stability imparted to these molecules. Focussing on proteins, we highlight here not just the key drivers behind protein-ionic liquid interactions that facilitate these functionalities, but address relevant current and potential applications of protein-ionic liquid interactions, including areas of future interest.

Reactive Compatibilization of PBT/EVA Blends with an Ethylene-Acrylic Acid Copolymer and a Low Molar Mass Bis-Oxazoline

2004

Polyesters and polyolefins form highly incompatible blends with poor properties and gross morphology that hinder any practical applications. In this work, the possibility to compatibilize an incompatible blend of poly(butylene terephthalate) (PBT) with ethylene vinyl acetate (EVA) by adding a bis-oxazoline compound, 2,2'-(1,3-phenylene)-bis(2-oxazoline) (PBO), and an ethylene acrylic acid copolymer (EAA) as compatibilizer precursors has been studied. The results indicate that the binary uncompatibilized blends show poor mechanical properties and a bad morphology with scarce adhesion between the phases. The situation is only slightly improved when the EAA is added while the best performance …

On the modification of the nitrile groups of acrylonitrile/butadiene/styrene into oxazoline in the melt

2000

Oxazoline functionality is well known to be highly reactive toward a lot of other functional groups like carboxyls, hydroxyls, mercaptans, and amines. In this work we report the possibility to modify the nitrile groups of an acrylonitrile/butadiene/styrene (ABS) copolymer into oxazoline in the molten state in the presence of aminoethanol as modifier agent and zinc acetate as a catalyst. The reaction has been carried out in a batch mixer and in a corotating twin screw extruder. The conversion of the nitrile groups into oxazoline has been verified by infrared spectroscopy, NMR analysis microanalysis and confirmed by thermomechanical characterization. The results indicate that the kinetic of g…
