    Administrátori počítačových sietí potrebujú nástroje na konfiguráciu a monitorovanie sieťových zariadení. Z tohto dôvodu bol vytvorený protokol NETCONF, určený na vzdialenú konfiguráciu, a modelovací jazyk YANG, ktorý popisuje štruktúru a sémantiku konfiguračných dát. Cieľom tejto práce je rozšírenie knižnice libyang o syntaktický analyzátor, ktorý spracováva modely popísané jazykom YANG a ukladá ich do interných štruktúr knižnice libyang. Tento analyzátor je vygenerovaný pomocou nástrojov bison a flex.Computer network administrators need tools for configuration and monitoring of network devices. Therefore, NETCONF protocol was designed for remote devices configuration and YANG modelling language which describes the structure of the configuration data. The aim of this thesis is to extend the libyang library with syntax parser, that processes models written in YANG and stores them into internal structures. This parser is generated by bison and flex tools.

    Long-term Inactive Data Retention through Tape Storage Technology

    Increasingly the need to retain digital documents indefinitely for legal, administrative or historical purposes is simply leading to a “save everything forever” approach. The authors argue that due to the technological reasons it is much easier to preserve large amount of documents in the electronic than in the paper form. Thus the selection procedures tend to be less restrictive than they used to be. Nevertheless, for most organizations it would be impossible to sustain this data growth forever. Archives, libraries, museums, institutions holding cultural heritage, as well as other companies and firms, are implementing solutions for creating digital archives, digital libraries, digital repositories and other types of storage systems aiming at long-term preservation of digital materials. Most of the data held in such systems are inactive for a long time, i.e. only a small set of data is frequently retrieved. Therefore, due to the specific needs of every organization, the storage planning process and the technology that is going to be used for storage and long-term preservation requires individual approach. The focus of this paper is on the retention of the long-term inactive data through tape storage technology. The authors will discuss current state of the art tape storage capabilities, and their advantages and disadvantages as a long-term storage and preservation solution

    Obrazovna inkluzija podrazumijeva najhumaniji odnos prema osobi s različitošću u razredu, školi i životnoj zajednici, te osposobljenost i obrazovanost svih za prihvaćanje svake osobe jednako, bez obzira na različitost. Razvoj inkluzivne kulture škole ovisi o učiteljima i nastavnicima, učenicima, stručnim suradnicima i ravnatelju. U ovom radu istražuje se učenička percepcija inkluzivne kulture u školi jer su učenici ti koji donose različitost u školu. Učeničkom procjenom tvrdnji u korištenom upitniku "Moja osnovna škola" koji ispituje elemente inkluzivne kulture škole na nacionalnom uzorku od 1952 učenika šestih i osmih razreda osnovne škole, dobiveni su rezultati istraživanja koji pokazuju da mlađi učenici percipiraju inkluzivnost u školi razvijenijom od starijih učenika, da učenici s najnižim školskim uspjehom percipiraju inkluzivnost u školi pozitivnije od učenika koji su na kraju školske godine postigli viši uspjeh, te da učenici iz sjeverne Hrvatske, Slavonije, Like i Banovine pozitivnije percipiraju inkluzivnost u svojim školama od učenika koji pohađaju školu u gradu Zagrebu. Prema ovom istraživanju vjerojatno su ometajući čimbenici u stvaranju inkluzivne kulture škole u predmetno-sadržajnoj usmjerenosti u školi, niskoj razini međupredmetne povezanosti, nedostatku vremena za odgojni rad zbog opterećenja nastavnim planom i programom te u pritisku zbog vanjskog vrednovanja i općenito učestalih testiranja učenika u školi.Educational inclusion implies the most humane attitude towards the person with diversity in the classroom, school and community life, as well as training and education of all to accept each person equally, regardless of their differences. The development of an inclusive school culture depends on teachers, pupils, educators and the principal. This paper explores pupils\u27 perceptions of inclusive culture in the school, because they are the ones that bring diversity to the school. Research results obtained from pupil assessment statements used in the questionnaire, "My primary school," which examines the elements of an inclusive school culture, on a national sample of 1,952 sixth and eighth graders, show the following results: younger students perceive inclusiveness in school to be more developed than older students; pupils with the lowest school achievement perceive inclusiveness in school more positively than pupils who achieved higher success at the end of the school year; and pupils from the region of North Croatia, Slavonia, Lika and Banovina more positively perceive inclusiveness in their schools than students who attend school in the city of Zagreb. According to this research results, probable hindering factors in creating of an inclusive school culture lie in the school’s subject and content orientation and low level of curricular connectedness, leaving no time for educational work due to the work load caused by curriculum, and the pressure of the external evaluation and generally frequent testing of students in school .Bildungseingliederung stellt die humanste Haltung dar gegenüber der Vielfältigkeit von Personen, welche im Klassenzimmern, Schulen und im Gemeindeleben, sowie in der Aus-und Weiterbildung zu finden sind. Bildungseingliederung meint, jeden Menschen gleichermaßen zu akzeptieren, unabhängig von jeglichen Unterschieden. Die Entwicklung einer inklusiven Schulkultur hängt von Lehrern, Schülern, Pädagogen, und Schuldirektoren ab. Der hier vorliegende Beitrag untersucht, wie Schüler inklusive Kultur in der Schule wahrnehmen, immerhin sind es die Schüler selbst, die Vielfalt in die Schule einbringen. Die hier dargestellten Forschungsergebnisse beruhen auf Antworten von Schülern im Rahmen eines Fragebogens "Meine Grundschule", welcher die Elemente einer inklusiven Schulkultur untersucht. Eine nationale Stichprobe von 1952 Schülern aus sechsten und achten Klassen wurde verwendet. Die Auswertungsergebnisse zeigen, dass jüngere Schüler weiter entwickelt sind als ältere Schüler in ihrere Wahrnehmung von Inklusivität in der Schule, dass die Schüler mit den niedrigsten Schulleistungen Inklusivität in der Schule positiver wahrnehmen als die Schüler, die am Ende des Schuljahres einen höheren Lernerfolg erreichten, und dass Schüler aus der Region Nordkroatien (Slawonien , Lika und Banovina) Inklusivität in der Schule positiver wahrnehmen als Schüler aus Schulen in der Stadt Zagreb. Laut dieser Studie scheinen die folgenden Faktoren die Schaffung einer inklusiven Schulkultur zu hemmen: bestimmte zweck- und inhaltliche Ausrichtungen von Schulen, ein niedriges Niveau der gegenseitigen Verbundenheit, ein Mangel an Zeit für die pädagogische Arbeit aufgrund überlasteter Lehrplane, der Druck durch externe Evaluierungen, und generell die Häufigkeit mit der Schüler in der Schule Prüfungen ausgesetzt sind

    Nearby Young, Active, Late-type Dwarfs in Gaia's First Data Release

    The Galex Nearby Young Star Survey (GALNYSS) has yielded a sample of \sim2000 UV-selected objects that are candidate nearby (D<D \stackrel{<}{\sim}150 pc), young (age \sim10--100 Myr), late-type stars. Here, we evaluate the distances and ages of the subsample of (19) GALNYSS stars with Gaia Data Release 1 (DR1) parallax distances D120D \le 120 pc. The overall youth of these 19 mid-K to early-M stars is readily apparent from their positions relative to the loci of main sequence stars and giants in Gaia-based color-magnitude and color-color diagrams constructed for all Galex- and WISE-detected stars with parallax measurements included in DR1. The isochronal ages of all 19 stars lie in the range \sim10--100 Myr. Comparison with Li-based age estimates indicates a handful of these stars may be young main-sequence binaries rather than pre-main sequence stars. Nine of the 19 objects have not previously been considered as nearby, young stars, and all but one of these are found at declinations north of ++30^\circ. The Gaia DR1 results presented here indicate that the GALNYSS sample includes several hundred nearby, young stars, a substantial fraction of which have not been previously recognized as having ages <\stackrel{<}{\sim}100 Myr.Comment: 30 pages, 4 tables, 7 figures; to appear in The Astrophysical Journal; 1st replacement to correct typos/omissions in Table 3 and acknowledgments; 2nd replacement to incorporate corrections to ApJ proof

    Draper Laboratory recently developed a Hardware-In-The-Loop Simulator (HILSIM) to provide a simulation of the Aerial Regional-scale Environmental Survey (ARES) airplane executing a mission in the Martian environment. The HILSIM was used to support risk mitigation activities under the Planetary Airplane Risk Reduction (PARR) program. PARR supported NASA Langley Research Center's (LaRC) ARES proposal efforts for the Mars Scout 2011 opportunity. The HILSIM software was a successful integration of two simulation frameworks, Draper's CSIM and NASA LaRC's Langley Standard Real-Time Simulation in C++ (LaSRS++)
