A GPU-accelerated augmented Lagrangian based L1-mean curvature Image denoising algorithm implementation
2015
This paper presents a graphics processing unit (GPU) implementation of a recently published augmented Lagrangian based L1-mean curvature image denoising algorithm. The algorithm uses a particular alternating direction method of multipliers to reduce the related saddle-point problem to an iterative sequence of four simpler minimization problems. Two of these subproblems do not contain the derivatives of the unknown variables and can therefore be solved point-wise without inter-process communication. Inparticular, this facilitates the efficient solution of the subproblem that deals with the non-convex term in the original objective function by modern GPUs. The two remaining subproblems are so…
The new role of the corporate and functional strategies in the tourism sector: Spanish small and medium-sized hotels
2005
This article aims at establishing the presence or lack of possible relationships between the existence of a logical global strategy definition in Spanish small and medium-sized hotels and its links with functional or department strategies involving four areas – marketing, technology, human resources and finance. Results show that there is a relationship between enterprise size – using business turnover as a yardstick – and the proper definition of technology, human resources and finance functions. There is also a relationship between enterprise size, determined by the number of employees, and an adequate definition of corporate strategy and technology and human resources department function…
Grafisko elementu pielietojums apkalpojošā personāla formas tērpu dizainā
2017
Grafiskie elementi formas tērpa dizainā ir svarīga korporatīvās identitātes sastāvdaļa. Slimnīcai, kā uzņēmumam ir svarīgi, kā iestādes koptēlā iekļaujas personāls. Autore sava darba ietvaros pēta medicīnas māsu formu vēsturi, to vizuālos nosacījumus, atbilstību darba drošībai, grafikas pielietojumu formas dizainā. Autore pievēršas problēmai, ka māsu formu grafiskais noformējums neatbilst 21.gs. sākuma medicīnas māsu prasībām.

Rola efektu podstawnikowego w chemii i naukach pokrewnych
2017
Zmiany struktury π-elektronowej pierścieniowych układów aromatycznych wywołane obecnością podstawników, stanowią ważne zagadnienie w dziedzinie chemii strukturalnej. Ma to swoje źródło w tzw. efekcie podstawnikowym, który w znacznym stopniu decyduje o reaktywności związków aromatycznych, jak również o innych właściwościach chemicznych, biologicznych i fizycznych. Efekt podstawnikowy jest terminem bardzo często używanym w literaturze chemicznej i pokrewnej, statystycznie każdego dnia pojawia się ponad 10 prac, w których pojęcie to występuje w tytule artykułu lub abstrakcie. Badania efektu podstawnikowego mają na celu poznanie wzajemnych interakcji pomiędzy podstawnikami przyłączonymi do pier…

Masteroppgave i helse- og sosialinformatikk HSI 500 Universitetet i Agder 2014 Implementation of personnel staffing and scheduling information systems receives growing attention both nationally and internationally. Goals include improvement of the efficiency and effectiveness of scheduling activities. Standardized scheduling activities, is expected to improve the quality of management information. The purpose of this study is to evaluate the implementation of Gat as a personnel staffing and scheduling information system at Sørlandet Sykehus HF. Data material was gathered through a quantitative survey based on defined scheduling activities through the RAPS-tutorial. The questions were catego…
En kartlegging av teknologiske hjelpemidler til personer med nyoppdaget demens
2014
Masteroppgave i helse- og sosialinformatikk HSI 500 Universitetet i Agder 2014 The main objective of the national program of welfare technology is that welfaretechnological solutions will be an integrated part of the health and care services within 2020.Several projects in this program will include safety packages. Before technological tools areimplemented, a survey regarding the needs and challenges should be conducted. The presentstudy has focused on people with dementia and their relatives, because in 2040, the number ofpeople with dementia is expected to double.Welfare technological solutions can be divided into three parts: fall, isolation, and cognitiveimpairment. Thus, the current st…
Concise and modular synthesis of regioisomeric haptens for the production of high-affinity and stereoselective antibodies to the strobilurin azoxystr…
2011
The immune response to regioisomeric haptens of azoxystrobin with varied derivatization sites was studied. Based on the Sonogashira and Suzuki-Miyaura couplings and following a straightforward modular design, we have synthesized four haptens with the same linker anchored through C-C bonds and located at different sites of the molecule. The most stereoselective antibodies were produced from immunogens with the spacer arm at a distal position from the β-methoxyacrylate moiety characteristic of strobilurins. Moreover, we observed that assay cross-reactivity was reliant on the functionalization site of the competitor derivative. Finally, the antibody binding site was explored using synthetic ch…
Klīniski nozīmīgas bakteriēmijas Rīgas multidisciplinārā slimnīcā
2020
Asinsrites infekcijas – bakteriēmijas globāli atzītas par vienu no galvenajiem iemesliem, kas ietekmē gan saslimstību, gan mirstību, un to incidence pieaug. Joprojām paliek neskaidrs, kas ietekmē dinamisku bakteriēmiju pieaugumu – izmaiņas patogēnsspecifiskā transmisijā, virulencē vai rezistencē, novecojusi populācija vai pārmērīgi kompleksa medicīnas aprūpe vai visu faktoru kombinācija. Viena no iespējām ir baktērijas adaptīvie atbildes mehānismi – antimikrobiālās rezistences veidošanās.

Stability analysis of black holes in massive gravity: a unified treatment
2014
We consider the analytic solutions of massive (bi)gravity which can be written in a simple form using advanced Eddington-Finkelstein coordinates. We analyse the stability of these solutions against radial perturbations. First we recover the previously obtained result on the instability of the bidiagonal bi-Schwarzschild solutions. In the non-bidiagonal case (which contains, in particular, the Schwarzschild solution with Minkowski fiducial metric) we show that generically there are physical spherically symmetric perturbations, but no unstable modes.
