Almost square Banach spaces
2014
We single out and study a natural class of Banach spaces -- almost square Banach spaces. In an almost square space we can find, given a finite set $x_1,x_2,\ldots,x_N$ in the unit sphere, a unit vector $y$ such that $\|x_i-y\|$ is almost one. These spaces have duals that are octahedral and finite convex combinations of slices of the unit ball of an almost square space have diameter 2. We provide several examples and characterizations of almost square spaces. We prove that non-reflexive spaces which are M-ideals in their biduals are almost square. We show that every separable space containing a copy of $c_0$ can be renormed to be almost square. A local and a weak version of almost square spa…

Unsteady Separation for High Reynolds Numbers Navier-Stokes Solutions
2010
In this paper we compute the numerical solutions of Navier-Stokes equations in the case of the two dimensional disk impulsively started in a uniform back- ground flow. We shall solve the Navier-Stokes equations (for different Reynolds numbers ranging from 1.5 · 10^3 up to 10^5 ) with a fully spectral numerical scheme. We shall give a description of unsteady separation process in terms of large and small scale interactions acting over the flow. The beginning of these interactions will be linked to the topological change of the streamwise pressure gradient on the disk. Moreover we shall see how these stages of separation are related to the complex singularities of the solution. Infact the ana…

Observer-Based Stabilization of Stochastic Systems with Limited Communication
2012
Published version of an article in the journal: Mathematical Problems in Engineering. Also available from Hindawi: http://dx.doi.org/10.1155/2012/781542 Open Access This paper studies the problem of observer-based stabilization of stochastic nonlinear systems with limited communication. A communication channel exists between the output of the plant and the input of the dynamic controller, which is considered network-induced delays, data packet dropouts, and measurement quantization. A new stability criterion is derived for the stochastic nonlinear system by using the Lyapunov functional approach. Based on this, the design procedure of observer-based controller is presented,which ensures asy…
Josephson Traveling Wave Parametric Amplifiers as Non-Classical Light Source for Microwave Quantum Illumination
2021
Abstract Detection of low-reflectivity objects can be enriched via the so-called quantum illumination procedure. In order that this quantum procedure outperforms classical detection protocols, entangled states of microwave radiation are initially required. In this paper, we discuss the role of Josephson Traveling Wave Parametric Amplifiers (JTWPAs), based on circuit-QED components, as suitable sources of a two-mode squeezed vacuum state, a special signal-idler entangled state. The obtained wide bandwidth makes the JTWPA an ideal candidate for generating quantum radiation in quantum metrology and information processing applications.

Izdomātu valodu funkcijas zinātniskās fantastikas literatūrā
2015
Zinātniskā fantastika vienmēr valdzināja lielu lasītāju skaitu ar savām neparastām izdomātām pasaulēm. Vēlme ‘apmeklēt’ jaunas izdomātas pasaules padara šo daiļliteratūras žanru tik populāru cilvēka vidū. Izdomātas pasaules iedzīvotāji pelna savu pašu izdomātu valodu. Tā nodrošina lasītājiem vēl dziļāko iesaistīšanās līmeni, lai iegremdētu alternatīvajā realitātē. Izdomātas valodas izveidošana nav tik vienkāršs process, nekā tas varētu likties sākumā. Šeit pastāv ievērojama autora un pat valodnieka darbs. Šī pētījuma mērķis ir aprakstīt izdomātas valodas un analizēt tās funkcijas Roberta Ensona Hainlaina ‘Bezdibenī’, Entonija Bērdžesa ‘Mehāniskajā apelsīnā’, Teda Čanga ‘Tavā dzīves stāstā’ …
Incorporating digital self-services into integrated mental health care:a physician’s perspective
2018
PurposeThis paper aims to enhance the current understanding of digital self-services (computerized cognitive behavioral therapy [cCBT]) and how they could be better incorporated into integrated mental health care from the physician’s perspective. Service marketing and information systems literature are combined in the context of mental health-care delivery.Design/methodology/approachAn online survey of 412 Finnish physicians was undertaken to understand physicians’ acceptance of cCBT. The study applies thematic analysis and structural equation modeling to answer its research questions.FindingsAdopting a service marketing perspective helps understand how digital self-services can be incorpor…
Adsorbents and columns in analytical high-performance liquid chromatography: A perspective with regard to development and understanding
2012
A brief historical survey is presented on the evaluation of silica adsorbents in analytical HPLC. The theory of analytical HPLC is mostly still being based on the height equivalent to a theoretical plate concept and the van Deemter equation that was derived from gas phase adsorption involving a linear adsorption isotherm and fast mass transfer kinetics. One can obviously wonder whether the use of the van Deemter equation is relevant and valid for the evaluation of the performance of HPLC systems, where most often the liquid solutes involve charged molecules in electrolytes and in very many cases the adsorbates are macromolecules having diffusion coefficients of small magnitude. Instead of t…
