Archeologia dziewiętnastowiecznej pamięci w insurekcyjnym tryptyku Jarosława Iwaszkiewicza ("Noc czerwcowa", "Zarudzie", "Heydenreich")

2013

Three short “insurrection” stories written by Jarosław Iwaszkiewicz in the years 1963–1974 have inspired various interpretations; it seems, however, that there are still many undeciphered codes, references, and allusions. The author’s metatextual comments as well as the implicit poetics of the stories make it possible to consider them as a dialogue with the historical, cultural and aesthetic heritage of the 19th century: as a form of its literary archeology. The article deals with many literary and aesthetic conventions employed in the stories, with the emphasis on the concept of sérénité and on various associations with 19th-century art. Notably, the scope of analysis includes such motifs …

Oltre l'illusionismo pittorico: i teatrini prospettici nell'architettura siciliana tra Seicento e Settecento

2015

Durante i primi trentanni del XVI secolo l'uso in Sicilia di composizioni scultoree in prospettiva subì un significativo sviluppo grazie all'opera di Antonello Gagini (1478ca-1536) che conferì un vero e proprio effetto tridimensionale alle immagini scolpite nel marmo dando luogo ai cosiddetti "teatrini prospettici". L'inizio artistico di Giacomo Serpotta (1656-1732) diede il via ad una nuova, breve ma significativa fase orientata verso nuovi effetti prospettici. During the first thirty of the 16th century the use in Sicily of perspective compositions in sculptural reliefs underwent significanti development thanks to the work of Antonello Gagini (1478ca-1536) who passed previous models and l…

Radiological Assessment of Pediatric Scoliosis Patients

2021

Nosaukums: Radioloģiskais izmeklējums pediatriskiem pacientiem ar skoliozi Autore: Saara Anni Susanna Suomalainen, medicīnas studente Darba vadītājs: Dr. med. Paulis Laizāns un Dr. med. Jānis Upenieks Priekšvēsture : Skolioze ir sānu novirze, kas pārsniedz 10 grādus no normāla mugurkaula, mērot pēc rentgenogrammas, un tāpēc, ka sānu līkne ir saistīta ar skriemeļu rotāciju līknes iekšienē, rodas trīsdimensiju deformācija. Idiopātiskā skolioze bērnu populācijā ir sadalīta trīs vecuma grupās - zīdaiņu, bērnu un pusaudžu. Radiogrāfiskais novērtējums ir galīgās diagnozes pīlārs. Labi uzņemtos rentgenogrammās var novērtēt segmentācijas anomāliju raksturojumu, izliekumu veidu un to elastību, kā ar…

A combined three-dimensional digitisation and subsurface defect detection data using active infrared thermography

2016

International audience; In recent years, NonDestructive Testing (NDT) systems have been upgraded with three-dimensional information. Indeed, combine the three-dimensional and thermal information allows a more meaningful analysis. In the literature, the data for NDT and three-dimensional (3D) reconstruction analysis are commonly acquired from independent systems. However, the use of two such systems leads to error analysis during the data registration. In an attempt to overcome such problems, we propose a single system based on active thermography approach using heat point-source stimulation to get the 3D digitization as well as subsurface defect detection. The experiments are conducted on s…

Neutron scattering and imaging: a tool for archaeological studies

2015

International audience; Neutron scattering and neutron imaging are powerful techniques for studying the structure of objects without damage, which is an essential prerequisite for investigations in Cultural Heritage domain, particularly in Archaeology. The deep penetration of neutrons in most materials allows for the study of relatively large objects. The contrast between similar materials, like metals in alloys, or that due to the presence of hydrogen atoms gives information about the internal structure of objects that have been modified or repaired in the past. Imaging and tomography give a 3-dimensional view of the whole object, permitting discrimination between different parts of the ob…

Sensorless control of induction motors using an extended Kalman filter and linear quadratic tracking

2017

Induction motors are the most commonly used prime-movers in industrial applications. Many induction motors supplied by frequency converters are coupled with a physical angular rotor position/velocity sensor which makes the drive complex and require maintenance. This paper presents a sensorless control structure to avoid using a physical angular rotor position/velocity sensor. The proposed method estimates and control the angular rotor velocity using optimal control theory. The optimal controller used in this paper is based on linear quadratic tracking and the states of the machine are estimated using an extended Kalman filter. Both the controller and the estimator utilize the same internal …

Computational volumetric reconstruction of integral imaging with improved depth resolution considering continuously non-uniform shifting pixels

2018

Abstract In this paper, we propose a new computational volumetric reconstruction technique of three-dimensional (3D) integral imaging for depth resolution enhancement by using non-uniform and integer-valued shifting pixels. In a typical integral imaging system, 3D images can be recorded and visualized using a lenslet array. In previous studies, many computational reconstruction techniques such as computational volumetric reconstruction and pixel of elemental images rearrangement technique (PERT) have been reported. However, a computational volumetric reconstruction technique has low visual quality and depth resolution because low-resolution elemental images and uniformly distributed shiftin…
