Generalized dimension distortion under planar Sobolev homeomorphisms

2009

We prove essentially sharp dimension distortion estimates for planar Sobolev-Orlicz homeomorphisms.

Homeomorphisms of Finite Distortion

2013

In this chapter we establish the optimal regularity of the inverse mapping in higher dimensions and optimal Sobolev regularity for composites. Moreover, we establish optimal moduli of continuity for mappings in our classes and we discuss orientation preservation and approximation of Sobolev homeomorphisms.

Images and Preimages of Null Sets

2013

In this chapter we study conditions that guarantee that our mapping maps sets of measure zero to sets of measure zero. We start with the problem in general Sobolev spaces, after which we establish a better result for mappings of finite distortion. Then we introduce a natural class of counterexamples to statements of this type and finally we give a weak condition under which the preimage of a set of measure zero has measure zero for mappings of finite distortion.

Mappings of finite distortion: a new proof for discreteness and openness

2008

We give a new and elementary proof of the known result: a non-constant mapping of finite distortion f : Ω ⊂ ℝn → ℝn is discrete and open, provided that its distortion function if n = 2 and that for some p > n − 1 if n ≥ 3.

A contribution to solve the problem of attributing harmonic distortion responsibility

2005

Owing to the proliferation of loads which draw nonsinusoidal currents, the current and voltage distortion in distribution systems is ever increasing. The correct identification of the source of distortion is important for attributing the responsibility of disturbances to utility and customers. In this paper, a new classification of the possible classes of responsibility is proposed, defining some conditions, based on the improvement of the method of decomposition of the current into conforming and nonconforming components, and of the method based on the evaluation of the sign of harmonic active powers, which allows their identification.

From the Golgi-Cajal mapping to the transmitter-based characterization of the neuronal networks leading to two modes of brain communication: Wiring a…

2007

After Golgi-Cajal mapped neural circuits, the discovery and mapping of the central monoamine neurons opened up for a new understanding of interneuronal communication by indicating that another form of communication exists. For instance, it was found that dopamine may be released as a prolactin inhibitory factor from the median eminence, indicating an alternative mode of dopamine communication in the brain. Subsequently, the analysis of the locus coeruleus noradrenaline neurons demonstrated a novel type of lower brainstem neuron that monosynaptically and globally innervated the entire CNS. Furthermore, the ascending raphe serotonin neuron systems were found to globally innervate the forebrai…

"SOHO" tīkla aparatūras izmantošana: problēmas un drošības aspekti

2015

Maģistra darbs vērsts uz padziļinātu tēmas „"SOHO" maršrutētāju pielietojums lokālajos tīklos un ar to saistītas problēmas” izpēti, kas iepriekš daļēji tikusi pētīta bakalaura darba ietvaros. Darba mērķis ir SOHO aparatūras problēmu un īpatnību izpēte, gan no programmatūras darbības, gan no to konfigurācijas skatupunktiem, kas pārsvarā ir saistīta ar drošības jautājumiem. Viens no galvenajiem uzdevumiem ir apkopot rekomendācijas izstrādātājiem, balstoties uz veiktajiem pētījumiem. Vēl viens uzdevums ir parādīt lasītājam, pat ja tas nav saistīts ar IT nozari, ka nepareizi nokonfigurēts maršrutētājs var apdraudēt lietotāju drošību, atsaucoties uz publiskā pētījumu datiem, kuru ir veicis pats …

Mediterranean Borders and Diaspora

2020

“And So Europe Dehumanized Itself”, the expression used by Toni Morrison regarding slavery, seems to have returned dramatically to current affairs. We seem to have plunged into a dystopian present in which the European Union, instead of governing the disruptive global migrations through appropriate policies, has expressed such nervousness – both at the popular and institutional levels – to give rise, in an unstoppable crescendo, to practices inspired by xenophobia and racism. It has led to the inhuman treatment of migrants (I refer both to shipwrecks at sea, a real massacre and to the torture and torture reserved for them in Libya with the complicity of European governments) and finally to …
