Fast Axial Scanning in 3D Imaging
2016
We establish the conditions for obtaining fast axial 3D microscopy with constant magnification, invariant resolution, and symmetrical displacement range. We demonstrate that liquid lenses permit the axial scanning free of mechanical movements and vibrations. This allows speeding-up the process and avoiding distortionsin the image of dynamic specimens.

Asymptotic observer of the link states of flexible joint robots with motor-side sensing
2015
This paper proposes an approach for observing the link states, i.e. angular position and velocity, of the robotic joints with elasticities, when only the motor-side sensing is available. By separating the state-dependent nonlinearities of the rigid manipulator dynamics a linear sub-model of the elastic joint robot is obtained in an observable state-space form. The standard asymptotic Luenberger state observer is then designed for the given motor position signal which is measured by encoder and rectified from the nonlinear contribution. The configurable poles of observer allow shaping the estimated states dynamics to be fast enough in relation to the actual resonant joint behavior. Therefore…
Cementa ražošanas procesa tehnoloģisko risinājumu ietekmes uz gaisa kvalitāti novērtējums
2015
Maģistra darbā pētīts cementa ražošanas tehnoloģiju radītais gaisa piesārņojums un tā izplatība SIA „Cemex” rūpnīcas teritorijā, Brocēnos, kur cementa ražošanā pašlaik izmanto sausā procesa tehnoloģiju. Lai gan sausā procesa tehnoloģiskie risinājumi ir energoefektīvāki un videi draudzīgāki, ražošanas procesa rezultātā rodas būtisks cieto daļiņu piesārņojums. Pētījuma ietvaros veikts pilns cieto daļiņu novērtējuma cikls – emisiju aprēķini, piesārņojuma izkliedes modelēšana un modelēšanas rezultātu validācija izmantojot cieto daļiņu mērījumus. Mērījumi veikti ar vairakkanālu lāzerskaitīšanas metodi, modelēšana – izmantojot Gausa dispersijas modeli AerMod. Darba parādīta dažādu cementa ražošan…
Treatment of Anderson-Fabry Disease
2020
Fabry disease is an X-linked disorder of glycosphingolipid metabolism that results in progressive accumulation of neutral glycosphingolipids, predominantly globotriaosylsphingosine (Gb3) in lysosomes, as well as other cellular compartments of several tissues, causing multi-organ manifestations (acroparesthesias, hypohidrosis, angiokeratomas, signs and symptoms of cardiac, renal, cerebrovascular involvement). Pathogenic mutations lead to a deficiency of the lysosomal enzyme alpha-galactosidase A (GLA). In the presence of high clinical suspicion, a careful physical examination and specific laboratory tests are required. Finally, the diagnosis of Fabry’s disease is confirmed by the demonstrat…
Image Content Enhancement Through Salient Regions Segmentation for People With Color Vision Deficiencies
2019
Color vision deficiencies affect visual perception of colors and, more generally, color images. Several sciences such as genetics, biology, medicine, and computer vision are involved in studying and analyzing vision deficiencies. As we know from visual saliency findings, human visual system tends to fix some specific points and regions of the image in the first seconds of observation summing up the most important and meaningful parts of the scene. In this article, we provide some studies about human visual system behavior differences between normal and color vision-deficient visual systems. We eye-tracked the human fixations in first 3 seconds of observation of color images to build real f…
Evaluation of the long-term treatment effects of idursulfase using statistical modelling: Data from the Hunter Outcome Survey (HOS)
2019
Treatment for mucopolysaccharidosis type II (MPS II Hunter syndrome) is available in the form of intravenous enzyme replacement therapy (ERT) with idursulfase (Shire, Lexington, MA, USA). This analysis used statistical modelling to evaluate the long-term treatment effects of idursulfase on selected clinical parameters based on data from HOS, a global, observational registry (Shire, Lexington, MA, USA). Mixed modelling was used to analyse data from male patients followed prospectively in HOS who had received idursulfase for 5-8 years and information available for two or more timepoints, of which one was pre-ERT. Data were excluded from patients with only pre-ERT information available, who ha…
Entre moneo e memini. Arquitectura funeraria militar en el sureste de Sicilia.
2023
Nel luglio del 1943 la costa sud-orientale della Sicilia fu teatro dello sbarco attuato dalle forze militari Alleate da cui prende avvio la liberazione dal nazi-fascismo dell’Italia e dell’Europa. Gli eventi bellici siciliani furono inevitabilmente piuttosto cruenti e videro un numero elevato di morti di soldati italiani, tedeschi e dei militari delle forze anglo-americane. Sin dagli anni Cinquanta del ’900, la Commonwealth War Grave Commission e la Volksbund, al fine di onorare i militari Alleati e tedeschi caduti in battaglia, avviarono la realizzazione di diversi cimiteri di guerra tra Agira, Catania, Siracusa e Motta Sant’Anastasia. I primi tre, progettati da Louis de Soissons, destinat…
Vucciria a Palermo: narrazioni contemporanee da Guttuso alla Street Art
2020
Piazza Caracciolo nella Vucciria a Palermo era una dei più antichi e un tempo floridi mercati della città. Purtroppo lo spopolamento prima e l’abbandono del mercato dopo ha determinato la decadenza dello stesso e della sua consistenza storica architettonica. La Vucciria, in età contemporanea, è stata ispiratrice di artisti, scrittori e registi, che come Guttuso, Sciascia, Taravella e Camilleri, che l’hanno immortalata nelle loro opere. Un rinnovato interesse alla conservazione e valorizzazione dell’area oggi è pure espresso dalla Street Art, che si aggiunge e indica una nuova vita per la città storica. Piazza Caracciolo in the Vucciria in Palermo was one of the oldest and once flourishing m…
Pienamente conservare per pienamente fruire: il paradigma della Vucciria di Palermo nel Progetto I-Access
2021
Già dal nome la città di Palermo rivela una delle sue peculiarità più significative, ovvero la capacità di accogliere: dal greco «Pan ormos» - tutto porto. In generale, consapevole della vocazione di Palermo, il mercato della Vucciria è stato scelto per illustrare i contenuti del Progetto Interreg Italia-Malta, I-Access di Implementare l'accessibilità alla fruizione e alla conoscenza del centro storico urbano e per le somiglianze e le differenze riscontrate nel La Valletta e Palermo. Il progetto I-ACCESS ha verificato un metodo per promuovere l'accessibilità in senso culturale e fisico e questa esperienza può essere ripetuta in altri centri storici. La conoscenza della realtà materiale del …
Optimal placement of quality sensors in water distribution systems
2019
Water supply infrastructures are crucial for the sustainable existence and development of modern cities [1,2]. Water distribution systems (WDSs) are complex structures formed by many elements designed and erected to transport water of sufficient quality from water sources to consumers. The amount of the above elements, which can reach up to tens of thousands of links and junctions, their frequently wide spatial dispersion and the WDS characteristic of being very dynamic structures make the management of real WDSs a complex problem [3-5]. Moreover, although the main objective is to supply water in the quantity and quality required, other requirements are essential, namely maintaining conditi…
