Subject:
autismus, Aspergerův syndrom, autobiografie, autism, Asperger syndrome, and autobiographies
Language:
Czech
Description:
Článek se zabývá analýzou tří autobiografií osob s autismem přeložených do češtiny – Nikdo nikde (Donna Williams), Život za sklem (Wendy Lawson) a Život s Aspergerovým syndromem: příběh psychoterapie (Christine Preissmann). Popisuje, jak autorky referují o svých specifických příznacích a zájmech, rodinných a partnerských vztazích a kariérách. Analyzuje, jaké strategie zvolily pro boj s autistickým postižením. Dochází k závěru, že lidé s autismem považují za nejtěžší jiné příznaky autismu, než bývá tradičně popisováno v učebnicích a monografiích o autismu. V případě těchto tří autobiografií je subjektivně nejhůře snášeno „smyslové přetížení“ ve vypjatých situacích. and Autobiographies of persons with autism: unknown views on inner experience of autistic handicap The article analyses three autobiographies of autistic individuals translated into the Czech language – Nobody nowhere (Donna Williams), Life behind glass (Wendy Lawson), and Life with Asperger syndrome: a story of psychotherapy (Christine Preissmann). It shows, how the authors describe their specific symptoms and interests, family and partner relationships and career. The analysis focuses on strategies that were selected by the authors for coping with the autistic handicap. It comes to a conclusion that autistic persons consider different symptoms to be the worst than those conventionally described in textbooks and monographs on autism. In these three autobiographies, sensory overload in stressful situations was estimated from the subjective point of view to be the most unpleasant symptom.

Subject:
GNSS coordinates, time series analysis, discontinuity detection, velocity changes, station displacements, ITRF, FODITS, and JPL
Language:
English
Description:
For over 25 years, the International GNSS Service (IGS) has been processing observational data from the Global Navigation Satellite Systems (GNSSs). Hence, long time series of station coordinates are available, however, they are burdened with discontinuities, station velocity changes, and gross errors. Discontinuities and periodic variations are caused by equipment changes at stations, earthquakes, geophysical processes, data problems, as well as local environmental changes. As a result, many approaches have been identified that identify and remove discontinuities in the GNSS coordinate time series. One of them is the program Finding Outliers and Discontinuities In Time Series (FODITS) implemented in the Bernese GNSS Software environment (Dach et al., 2015), developed by the Astronomical Institute, University of Bern. The program is designed for the automatic analysis of time series, in which the functional model is adapted to the time series of coordinates depending on the adopted parameters. This study presents the analysis of long-term GNSS coordinate time series reprocessed in the framework of the realization of the International Terrestrial Reference Frame 2014 (ITRF2014) using the FODITS program. The results show that the optimum confidence level for the autonomous detection of station discontinuities in FODITS is 99% and 98%, for 7-day and 3-day GNSS solutions, respectively, when compared to the manual discontinuity detection from ITRF2014. However, the manual analysis unsupported by statistical tests as conducted in ITRF2014 may contain errors over which further elaboration is indispensable. On the other hand, routine interpretation of GNSS coordinate time series in a fully autonomous manner, although much faster, is not free from drawbacks, in particular in detecting appropriate epochs of discontinuities and changes in station velocities.

2627. Automata with modulo counters and nondeterministic counter bounds

Type:
model:article and TEXT
Subject:
multi-head automata, counter automata, modulo counters, stateless automata, and restricted nondeterminism
Language:
English
Description:
We introduce and investigate Nondeterministically Bounded Modulo Counter Automata (NBMCA), which are two-way multi-head automata that comprise a constant number of modulo counters, where the counter bounds are nondeterministically guessed, and this is the only element of nondeterminism. NBMCA are tailored to recognising those languages that are characterised by the existence of a specific factorisation of their words, e. g., pattern languages. In this work, we subject NBMCA to a theoretically sound analysis.

2628. Automata with two-sided pushdowns defined over free groups generated by reduced alphabets

Type:
model:article and TEXT
Subject:
pushdown automata, modifications, and recursively enumerable languages
Language:
English
Description:
This paper introduces and discusses a modification of pushdown automata. This modification is based on two-sided pushdowns into which symbols are pushed from both ends. These pushdowns are defined over free groups, not free monoids, and they can be shortened only by the standard group reduction. We demonstrate that these automata characterize the family of recursively enumerable languages even if the free groups are generated by no more than four symbols.

2629. Automated reverse Engineering of CAN protocols

Type:
model:article and TEXT
Subject:
controller area networks, statistical analysis, and neural networks
Language:
English
Description:
Car manufacturers define proprietary protocols to be used inside their vehicular networks, which are kept an industrial secret, therefore impeding independent researchers from extracting information from these networks. This article describes a statistical and a neural network approach that allows reverse engineering proprietary controller area network (CAN)-protocols assuming they were designed using the data base CAN (DBC) file format. The proposed algorithms are tested with CAN traces taken from a real car. We show that our approaches can correctly reverse engineer CAN messages in an automated manner.

Language:
Slovak
Description:
Uncertainty in estimation of hydraulic conductivity function from the retention curve limits the possibility of accurate quantitative predictions of water flow in natural heterogeneous porous media. Experiments were conducted on large undisturbed soil samples to measure hydraulic conductivity function directly. As a next stage, an enhanced set-up with fully automated data acquisition was developed to allow long infiltration-outflow experiments under variable saturated conditions. To control the upper boundary condition the tension infiltration disc is used. The inflow and the outflow rate are recorded continuously. The soil water pressure heads are measured at three different heights. Continuous weighing of the sample during the experiment monitors changes in the soil water content. For undisturbed soil sample of coarse sandy loam, a sequence of experimental runs was performed, each represented by a constant suction pressure head applied to the soil surface. The initial conditions of each run were the same. All experimental runs show several noticeable stages, the bulk soil water content changes during those stages are presented here. Automation of the experimental set-up allowed the extension of the experiment duration and improved the accuracy of the data. Because of the long experiment duration, remarkable phenomenons were observed. and Nejistota v odhadu funkce hydraulické vodivosti z retenční čáry znemožňuje přesnou kvantitativní predikci pohybu vody v přírodním heterogenním pórovém prostředí. Pro přímé měření funkce hydraulické vodivosti byly provedeny experimenty na velkých neporušených vzorcích půd. Vylepšením těchto experimentů je experimentální sestava s plně automatizovaným záznamem měřených hodnot, která umožňuje provádění dlouhých infiltračně-výtokových experimentů při různém nasyceni půdy. Pro nastavení horní okrajové podmínky je použito podtlakového infiltrometru. Infiltrace a výtok jsou automaticky kontinuálně měřeny a zaznamenávány. Sací tlakové výšky jsou měřeny ve třech různých místech vzorku. Kontinuálním měřením vzorku je umožněno sledování změn okamžité vlhkosti půdy během experimentu. Na neporušeném vzorku hlinitopísčité půdy byla provedena série experimentálních běhů, přičemž při každém z nich byla nastavena určitá sací tlaková výška aplikovaná na povrchu vzorku. Počáteční podmínka všech experimentálních běhů byla stejná. Záznamy jednotlivých experimentálních běhů se vyznačují několika významnými fázemi, v článku jsou ukázány změny celkového objemu vody ve vzoku během těchto fází. Automatizací experimentální sestavy bylo umožněno prodloužení doby trvání experimentálních běhů a byla zvýšena přesnost měření. Díky dlouhému trvání experimentu byly pozorovány některé významné jevy.
