Impulsive control on the synchronization for a class of chaotic Systems
2014
In this paper, the impulsive control problem on the synchronization for a class of chaotic systems is discussed. Based on Lyapunov stability theory, the new impulsive synchronization strategy is presented to realize the chaos synchronization and possesses the wider scope of application. Finally the numerical simulation examples are given to demonstrate the effectiveness of our theoretical results.
H<inf>&#x221E;</inf> controller design for the synchronization of a hyper-chaotic system
2013
In this paper, the robust control on the synchronization of a hyper-chaotic system is investigated. Based on Lyapunov stability theory and linear matrix inequality techniques, the multi-dimensional and the single-dimensional robust H∞ synchronization controllers are constructed for the possible application in practical engineering. Some numerical simulations are provided to demonstrate the effectiveness of the presented controllers.
Kredītiestāžu uzraudzības kompetenču sadale vienotā uzraudzības mehānisma ietvaros
2019
Vienotais uzraudzības mehānisma izveidošana ir unikāla Eiropas Savienības konstitucionālajā un administratīvajā sistēmā. Tā ir finanšu uzraudzības sistēma, ko veido ECB un nacionālās kompetentās iestādes. Tas, ka vienotā uzraudzības mehānisma pamatā ir dažādi autonomi elementi, kas atrodas gan nacionālajā, gan Eiropas Savienības līmenī, rada plašas sekas no juridiskās zinātnes viedokļa. Vienotā uzraudzības mehānisma īpašā struktūra rada jautājumus par mijiedarbību starp dažādajiem administratīvajiem līmeņiem un veidiem, kā dažādu līmeņu dalībnieki sadarbojas, lai īstenotu kopīgus uzdevumus un politiskos mērķus. Šī iemesla dēļ ir aktualizējies jautājums par kompetenču sadali starp ECB un nac…
Eksperimentāla mikroorganismu identifikācija punktātos, izmantojot mikrodaļiņas un spektrofotometru
2019
Ievads: Uz doto brīdi pastāv dažādas mikroorganismu diagnostiskas metodes, taču cilvēki joprojām cieš no infekcijas slimībām, kā arī mikroorganismu rezistence turpina augt. Tas liek aizdomāties par to, ka joprojām nav izdomāta ātra, lēta un maksimāli efektīva diagnostiskas metode. Jaunievedums – ir sen aizmirsts vecais. Spektrofotometrija ir sena metode, taču pagaidām netiek izmantota mikroorganismu atpazīšanai, kas dod iespēju pamēģināt uzlabot un renovēt to. Pētījuma mērķis ir noskaidrot mākslīgā bāzes punkāta absorbcijas pakāpi, pie kuras varētu identificēt mikroorganismus, izmantojot spektrofotometru un silīcija dioksīda mikrodaļiņas. Materiāli un metodes: Pētījumā tiek izmantotas 5 gra…
S29i attribution of the 1.3 mT hyperfine structure of the E′γ centers in amorphous SiO2
2009
We report an experimental investigation by electron paramagnetic resonance of the doublet of lines split by ∼1.3 mT and centered on the E′γ; center resonance line in the spectrum of irradiated amorphous SiO2 . Commercial and sol-gel materials, some of which subjected to hydrogen-deuterium exchange, were investigated. Exposure to γ or Β rays at room temperature of the samples and subsequent thermal treatments were carried out to induce the defects and to study their thermal stability. In all the materials used the ratio between the signal of the E′γ centers and that of the 1.3 mT doublet is constant and independent of the OH and OD contents. Furthermore, the 1.3 mT doublet and the E′γ center…
Paradossi dell’eloquenza senza tempo: Elogio di Nulla/Elogio di Qualcosa
2011
Nulla è dunque più importante di Nulla, un personaggio impalpabile e invisibile, di cui tuttavia percepiamo la presenza, quasi che il significato di questa parola nascondesse un fondo affermativo che solo l’acutezza della scrittura paradossale riesce a far riemergere, negando la nullità del Nulla, ovvero affermandone l’insospettabile consistenza.
Epidemiology and patterns of tracheostomy practice in patients with acute respiratory distress syndrome in ICUs across 50 countries
2018
Background: To better understand the epidemiology and patterns of tracheostomy practice for patients with acute respiratory distress syndrome (ARDS), we investigated the current usage of tracheostomy in patients with ARDS recruited into the Large Observational Study to Understand the Global Impact of Severe Acute Respiratory Failure (LUNG-SAFE) study. Methods: This is a secondary analysis of LUNG-SAFE, an international, multicenter, prospective cohort study of patients receiving invasive or noninvasive ventilation in 50 countries spanning 5 continents. The study was carried out over 4 weeks consecutively in the winter of 2014, and 459 ICUs participated. We evaluated the clinical characteris…
Samuel Fernberger's rejected doctoral dissertation: A neglected resource for the history of ape research in America.
2009
I summarize a never-completed 1911 doctoral dissertation on ape behavior by Samuel Fernberger of the University of Pennsylvania. Included are observations on many behavioral patterns including sensory and perceptual function, learning, memory, attention, imagination, personality, and emotion in an orangutan and two chimpanzees. There are examples of behavior resembling insight, conscience, tool use and imitation. Language comprehension was good but speech production was minimal. The document appears to contradict a brief published article on the project by William Furness in that punishment was frequently used. The document is important for understanding Fernberger's early career, for antic…
Deep dry needling of trigger points located in the lateral pterygoid muscle: efficacy and safety of treatment for management of myofascial pain and t…
2014
Background To determine whether deep dry needling (DDN) of trigger points (TPs) in the lateral pterygoid muscle (LPM) would significantly reduce pain and improve function, compared with methocarbamol/paracetamol medication. Material and Methods Forty-eight patients with chronic myofascial pain located in the LPM were selected and randomly assigned to one of two groups (DDN test group, n=24; drug-treated control group, n=24). The test group received three applications of needling of the LPM once per week for three weeks, while control group patients were given two tablets of a methocarbamol/paracetamol combination every six hours for three weeks. Assessments were carried out pretreatment, 2 …
Authoritarianism and the transgenerational transmission of corporal punishment.
2019
Abstract Background Authoritarianism, firstly described by Horkheimer in 1936, is characterized by submission to authorities, aggression against subordinates and conventionalism. Authoritarianism is discussed as major contributor for right-wing attitudes. Horkheimer hypothesized that authoritarianism has its origin in the experience of harsh parenting and exposure to corporal punishment (CP) by authoritarian parents. The other way around, literature points towards an association between conventionalism and support of CP as disciplinary method, suggesting a role of authoritarianism in the vicious cycle of transgenerational transmission of CP. Objective We aimed to assess the association of a…
