New mobility strategies for the development of tourism in Sicily

2012

Tourism and Transport is a well established and inseparable pair. An areas can increase the tourism in potentially own economy. This requires suitable accommodation and adequate transportation system. A positive synergy effects are induced to increase of the site. Transport is an important growth area for tourism and as a result. A better functioning of transport facilitates access to sites, decreases the cost of transport and increases tourist flows. In Sicily there are a wealth of artistic, archaeological and natural sites, generating a tourist flows during the year. Despite this, the network of connections and services is precarious. Residents and visitors are inaccessible to certain geo…

An empirically grounded agent based model for modeling directs, conflict detection and resolution operations in air traffic management

2017

We present an agent based model of the Air Traffic Management socio-technical complex system that aims at modeling the interactions between aircrafts and air traffic controllers at a tactical level. The core of the model is given by the conflict detection and resolution module and by the directs module. Directs are flight shortcuts that are given by air controllers to speed up the passage of an aircraft within a certain airspace and therefore to facilitate airline operations. Conflicts resolution between flight trajectories can arise during the en-route phase of each flight due to both not detailed flight trajectory planning or unforeseen events that perturb the planned flight plan. Our mod…

Eksperiments metodoloģijā: Starp “Virtuālo” un “Īsto”

2018

Bakalaura darbs “Eksperiments metodoloģijā: Starp “Virtuālo” un “Īsto”” fokusējas uz video spēļu spēlētāju imersīvām pieredzēm, kuras izraisa masīvās daudzspēlētāju tiešsaistes lomu spēles World of Warcraft virtuālās pasaules vizuālās un skaņas ainavas. Es skatu virtuālu spēļu pasauli kā digitālu kultūras artefaktu, kas sastāv no vairākām mākslas formām, un es pievēršu uzmanību veidiem, kādos šīs mākslas formas var sekmēt cilvēku radošumu un imersiju, kā arī dzīves uzskatus un tās trajektoriju virzienus ārpus virtuālā lauka. Konceptualizējot virtuālās ainavas kā atmiņu piesātinātas, es atsedzu un analizēju neaizmirstamas cilvēku pieredzes dziļumu, kas tajās ir iesakņots. Eksperiments ar etn…

The space age and the origin of space research

2001

The exploration of space is one of the greatest achievements of the twentieth century. In the ideal photo album of this century one could hardly avoid including such pictures as our blue planet seen from space and the human footprint on the Moon’s surface; the close-up images of a comet’s nucleus and the rough landscape of Mars; the floating of astronauts in the black vacuum around a space station and the rings of Saturn photographed from an approaching spacecraft.

Redemption and home in the african american city upon a hill: hannah crafts’s the bondwoman’s narrative.

2019

The Bondwoman’s Narrative (1857) is a novel in which the black female slave Hannah Crafts aims at the remodeling of her society and to gain self–assertion through a deeply Christian commitment and a total and honest respect to the values it impinges drawing broadly on the Bible and reshaping biblical imagery to convey her message and to submit her subjectivity and her Americanness. By using the national continuum of jeremiad rhetoric and her attachment to the values of the Christian creed, the novel partakes and yet takes a different direction from slave narratives by cagily forerunning Du Bois’s praised theory of the double consciousness. In so doing, it positions its protagonist as the fi…

An Extended Kalman Filter-Based Technique for On-Line Identification of Unmanned Aerial System Parameters

2015

ABSTRACT: The present article deals with the identification, at the same time, of aircraft stability and control parameters taking into account dynamic damping derivatives. Such derivatives, due to the rate of change of the angle of attack, are usually neglected. So the damping characteristics of aircraft dynamics are attributed only on pitch rate derivatives. To cope with the dynamic effects of these derivatives, authors developed devoted procedures to estimate them. In the present paper, a complete model of aerodynamic coefficients has been tuned-up to identify simultaneously the whole set of derivatives. Besides, in spite of the employed reduced order model and/or decoupled dynamics, a s…

Organocatalytic Enantioselective Functionalization of Hydroxyquinolines through an Aza-Friedel-Crafts Alkylation with Isatin-derived Ketimines

2018

[EN] A highly enantioselective addition of hydroxyquinolines to isatin-derived ketimines has been realized using a quinine-derived thiourea organocatalyst. The reaction affords chiral 3-amino-2-oxindoles bearing a quinoline moiety with a quaternary stereocenter in high yields (up to 98%) and excellent enantioselectivities (up to 99%). Moreover, we can extend this methodology for the enantioselective functionalization of 5-hydroxyisoquinoline. This methodology represents, to the best of our knowledge, the first enantioselective addition of hydroxyquinolines to imines.

USE OF PASSENGER LOCATION CARDS IN THE ERA OF THE COVID-19 PANDEMIC, AND THE PROCESSING OF PERSONAL DATA OF AIR PASSENGERS

2021

Purpose: The aim of the article is to analyse the processing of personal data of air passengers during the SARS-CoV-2 pandemic in the context of doubts that have arisen in connection with the need for these passengers to provide their personal data as part of filling out the Passenger Location Card questionnaire. Method: The research method used in this study is case study. Findings: In the study, it was showed that firstly, the data of air passengers processed in relation to the application of the Passenger Location Card by the State Border Sanitary Inspectorate in Warsaw should be protected under the provisions of the General Regulation on the protection of personal data. Furthermore, the…

The Ultra-Fast Flash Observatory's space GRB mission and science

2011

AbstractThe Ultra-Fast Flash Observatory (UFFO) is a space mission to detect the early moments of an explosion from Gamma-ray bursts (GRBs), thus enhancing our understanding of the GRB mechanism. It consists of the UFFO Burst & Trigger telescope (UBAT) for the recognition of GRB positions using hard X-ray from GRBs. It also contains the Slewing Mirror Telescope (SMT) for the fast detection of UV-optical photons from GRBs. It is designed to begin the UV-optical observations in less than a few seconds after the trigger. The UBAT is based on a coded-mask X-ray camera with a wide field of view (FOV) and is composed of the coded mask, a hopper and a detector module. The SMT has a fast rotata…
