Simulation and Parameter-Identification of the Closed-Loop Cardiovascular System by the Use of a Nonlinear Mathematical Model
1981
Abstract A non-linear model of human cardio-vascular system, which includes the short-term pressure regulation mechanism was mathematically derived and implemented on a PDP-11/45 in a block-oriented, interactive programming language. In this way the behaviour of the arterial and venous pressures, cardiac output, stroke volume, total peripheral resistance and heart-rate under ergometric workload was studied by simulation, and experimentally proved, that the model matches the system with good accuracy. In a second phase the parameters of the model were identified by the use of the output-error method. For this purpose a non-linear system identification programming package was applied. The par…
Advanced Spectroscopic Detectors for Identification and Quantification
2013
The coupling of vibration spectroscopic detectors to liquid chromatography (LC) is an interesting analytical tool that allows combining high resolution from LC with molecular specific information accessible by infrared (IR) and Raman spectrometry. This chapter describes the basics of IR and Raman spectroscopy with a special emphasis on the advantages and pitfalls of these detection techniques in LC. Two fundamentally different coupling approaches, namely, off-line hyphenation involving the physical elimination of the mobile phase and on-line hyphenation through the use of flow cells, are discussed in detail, describing the most important interfaces and diverse practical applications. Strate…
Structurally Uniform Oligomers
1985
Model compounds as well as prototype reactions are frequently used to understand more complex chemical systems. In the case of phenolic resins a large number of model compounds have been synthesized. They are regarded as either components of a complex mixture of novolaks or resoles or as representative segments of the phenolic crosslinked network. These model compounds were formerly the basis for the correlation of physical properties to molecular structure. Presently the progress of analytical separations and identification methods is formidable; highly sophisticated chemical instrumentation allows the analysis of highly complex mixtures. Nevertheless, well defined compounds with definite …
Experimental realization of a Persistent Identifier Infrastructure stack for Named Data Networking
2015
The continuation of Persistent Identifier Infrastructures is crucial when next-generation Internet architectures based on Information-Centric Networking (ICN) arise. When moving to ICN, we must ensure the resolution of Persistent Identifiers (PID), such as the billions of Digital Object Identifiers (DOI) used today, to provide continued access to scientific literature and research data. It provides the base for the necessary transformations in the Handle System architecture and protocol for running a PID system on the Named Data Networking (NDN) architecture, which is a recent incarnation of ICN. Furthermore, it examines the PID-specific resolution access patterns, investigates the expected…
Nursing students’ professional identity development: An integrative review
2021
The aim of this integrative review was to identify and synthesize current evidence of factors that influence the professional identity development of nursing students in nursing educational programs. Cinahl (EBSCO), Medline, ERIC, Embase, and PsycINFO were searched. Three different appraisal tools and the PRISMA checklist were used. The data from both quantitative and qualitative studies (19 primary studies) were analyzed by applying qualitative content analysis. The analysis revealed two main themes: a caring practice–academic partnership and support in the learning environment. The following seven sub-categories were identified: clinical supervisors, ethical competence, preparation, self…
Sākumskolas skolēnu ar mācīšanās traucējumiem iekļaušana izglītībā
2021
Artas Zverovas diplomdarbs “Sākumskolas skolēnu ar mācīšanās traucējumiem iekļaušana izglītībā” tika izstrādāts ar mērķi izpētīt skolēnu ar mācīšanās traucējumiem un to iekļaušanu izglītības iestādē. Veikt pētījumu par skolēnu ar mācīšanās traucējumiem iekļaušanu izglītībā. Izstrādāt un aprobēt sociālpedagoģiskās darbības programmu bērniem ar mācīšanās traucējumiem iekļaujošajā izglītībā. Teorētiskajā daļā tika raksturoti mācīšanās traucējumi, iekļaujošā izglītība un atbalsta sistēmas raksturojumi, skolēnu iekļaušanai izglītībā. Prakstiskajā daļā tika veikts pētījums par skolēnu ar mācīšanās traucējumiem iekļaušana izglītības iestādē un izstrādāta sociālpedagoģiskās darbības programma skolē…
Hipotekārā kredīta tirgus Latvijā
2015
Bakalaura darba tēma ir „Hipotekārā kredīta tirgus Latvijā”. Hipotekārai kreditēšanai Latvijas attīstības dažādos periodos ir bijusi ļoti nozīmīga loma ekonomikas izaugsmē, taču līdz ar krīzes iestāšanos hipotekārā kreditēšana savas pozīcijas ir zaudējusi. Šī nozare vairs nav tik spēcīga kā agrāk, tādēļ valdība cenšas ar dažādu atbalsta programmu palīdzību atjaunot hipotekārās kreditēšanas apjomu pieaugumu. Darbā tiek aprakstīti hipotekārās kreditēšanas ietekmējošie faktori, kuriem ir gan tieša, gan netieša ietekme uz hipotekāro kreditēšanu. Bakalaura darba mērķis ir uz veiktās hipotekārās kreditēšanas analīzes pamata veikt secinājumus par to, kādi faktori ietekmē hipotekāro kreditēšanu, kā…
Uzņēmuma SIA "DSV Latvia" transporta vadības programmas modernizācija
2022
Loģistikas uzņēmums SIA “DSV Latvia” jau vairākus gadus darbojas veiksmīgi loģistikas nozarē Latvijā. Tās pamatprincipi balstās uz operatīvu ekselenci, kur viss notiek noteiktajā laikā un vietā, kā arī pašiem cilvēkiem - gan darbiniekiem, gan klientiem, uzturot viņu labsajūtu pēc iespējas labāku. Tomēr, attīstoties mūsdienu tehnoloģijām un arī loģistikas nozarei, uzņēmums, tieši kravu transportēšanas departamentā, atpaliek no saviem konkurentiem, jo izmanto novecojušu transporta vadības sistēmu. Pašlaik efektīvu darbību šajā departamentā uztur paši darbinieki ar savu profesionālismu un neatlaidību, tāpēc ir jārada risinājums transportēšanas vadības sistēmā situācijā, lai nākotnē tas varētu …
An immune system model in discrete time based on the analogy with the central nervous system
1988
Jerne's model for the immune system formulated in terms of a neural network recently proposed by Weisbuch and Atlan is generalized to interactions with continuous coupling coefficients. It is shown that even the extended model can be solved analytically without the aid of computer simulations and exhibits one additional attractor, which corresponds to a configuration with high concentrations of active killer cells eventually causing death of the organism.
Real-world impact of rotavirus vaccination in European healthcare settings: a systematic literature review
2022
INTRODUCTION: Rotavirus is one of the most common pathogens causing diarrhea in children <5 years and has a major impact on childhood morbidity and mortality. Since the implementation of rotavirus vaccines into childhood immunization programs across Europe, there has been a reduction in rotavirus burden, including hospitalizations, outpatient cases, costs, and deaths. AREAS COVERED: A systematic literature review identified publications describing the clinical and economic impact of rotavirus vaccinations across Europe, from their introduction in 2006 to the end of 2020. A total of 3,137 articles were identified, of which 46 were included in the review. Included articles reported the impact…
