Minimizing the condition number of a positive definite matrix by completion
No full textElsner L, He C, Mehrmann V. Minimizing the condition number of a positive definite matrix by completion. Numerische Mathematik. 1994;69(1):17-23.We consider the problem of minimizing the spectral condition number of a positive definite matrix by completion: [GRAPHICS] where A is an n x n Hermitian positive definite matrix, B a p x n matrix and X is a free p x p Hermitian matrix. We reduce this problem to an optimization problem for a convex function in one variable. Using the minimal solution of this problem we characterize the complete set of matrices that give the minimum condition number
Proposal measures for the reactivation of industrial degraded areas in the case of the Zasavje statistical region
No full textV magistrskem delu smo se dotaknili problematike industrijskih degradiranih območij v Sloveniji. Sprva smo pregledali različne definicije degradiranega območja, tako tuje kot tudi slovenske. Pregledali in proučili smo slovenske in evropske iniciative na temo degradiranih območij in raziskali različna merila za določitev le teh. Sledil je pregled različnih ukrepov in strategij. Pregledali smo tudi številne primere dobrih praks prenove degradiranih industrijskih območij in poizkušali ugotoviti, na kakšen način so se lotili prenove. V magistrski nalogi smo v aplikativnem delu obravnavali Zasavsko statistično regijo, ki velja za najbolj degradirano regijo v Sloveniji. Regijo smo podrobno proučili in s pomočjo spletne aplikacije za vodenje evidence FDO poiskali industrijska degradirana območja v Zasavski regiji. Območja smo si ogledali na terenu in jih podrobno analizirali, izvedli smo tudi polstrukturiran intervju z nekaterimi lastniki zemljišč. Raziskava je pokazala, da je večina območij v lasti pravnih oseb, nekaj območij pa je v javni lasti. V zaključku naloge smo nato predlagali še ukrepe za reaktivacijo degradiranih industrijskih območij.In this master’s thesis the author discussed the problems of industrial degraded areas in Slovenia. The first task was to review various definitions of the degraded area, both foreign and Slovenian. The next step was to review and study Slovenian and European initiatives in degraded areas and investigate various criteria for determining degraded areas, which was followed by an overview of various measures and strategies. Several examples of good practice in the field of renovation of degraded industrial sites were examined, whereby the author tried to determine the renewal approach that was applied. In the empirical part of this thesis, issues in Zasavje statistical region, which is considered to be the most degraded region in Slovenia, were addressed. The region was examined in detail and industrial degraded areas in Zasavje region were determined by means of an online record-keeping application FDO (Functional degraded areas). The author has visited the examined areas, analysed them in detail, and conducted some semi-structured interviews with some landowners. The research has shown that the majority of the areas is owned by legal entities and that some areas are publicly owned. In the conclusion, the author suggested the measures that should be taken to reactivate degraded industrial sites
Relation of skewness factor and convection velocity in turbulent boundary layer
No full textThe paper is devoted to prove the relation between skewness factor and convection velocity in turbulent boundary layer. It appears that skewness factor can be used as an indicator of convection velocity of coherent structures, which is not always equal to the average flow velocity. The analysis has been performed based upon velocity profiles measured with hot-wire technique in turbulent boundary layer with pressure gradient corresponding to turbomachinery conditions. The results show that the cross product term of skewness factor decomposed by spectral filtering, which is also alternative measure of amplitude modulation, describes the convection velocity in zero pressure gradient turbulent boundary layer
Validation of the symptom and problem checklist of the german hospice and palliative care evaluation (hope)
No full textContext. The German Hospice and Palliative Care Evaluation (HOPE) is a national, long-term quality assurance project. Every year, German hospice and palliative care institutions document a core data set for their patients for a period of three months. Objectives. To validate the multidimensional symptom and problem checklist (HOPE-SP-CL) of the core data set and report details on reliability and validity. Methods. Data from yearly evaluation periods between 2002 and 2009 were used to calculate construct and convergent validity, internal consistency, test-retest reliability, and documentation discipline and acceptance of the core documentation system. Results. The HOPE-SP-CL includes items on physical, nursing, psychological, and social symptoms and problems. Factor analysis extracted four low to moderately intercorrelating factors with eigenvalues greater than 1.0 explaining 56% of the total variance. Discriminant validity of the HOPE-SP-CL showed good properties in detecting patient groups with different symptom intensities and overall symptom burden using the Eastern Cooperative Oncology Group performance status and primary cancer diagnosis as external validation criteria. The global sum score of the HOPE-SP-CL correlated most closely with the Palliative Outcome Scale staff version (r = 0.750). Internal consistencies ranged between alpha = 0.768-0.801 at three different times of assessment. Test-retest coefficients showed moderate to high correlations at one-week intervals. Conclusion. Analyses of reliability and validity of the HOPE-SP-CL showed satisfactory to good psychometric properties; therefore, the HOPE-SP-CL can be recommended for standard implementation in German hospice and palliative care institutions.

Palliative sedation in Germany: how much do we know? A prospective survey
No full textBackground: Little is known about the practice of palliative sedation (PS) in Germany. This paper presents an analysis of sedation-related data obtained from the German standardized core documentation system (HOPE) for palliative care patients. Methods: HOPE was complemented by an optional module on ethical decision making (EDM) which was pretested in 2004, data was collected in 2005-6 during the annual 3-month census. Data was analyzed descriptively from palliative care units (PCU - representative) and inpatient hospice (H - non-representative control group). Chi(2) test was used to test for differences between the reported data per item and year within one kind of setting (significance level p <= 0.05). Free-text entries were categorized inductively. Results: Datasets were obtained for 1,944 patients (P) with EDM. PS was performed in 13.0/11.8% (2005/2006) P in palliative care units (PCU) and 25.5/22.9% in hospices (H). Main reasons for PS in PCU were dyspnea, pain, fear or anxiety, in H reasons were inconsistent, high prevalence of psychosocial reasons. Most PS in PCU and about half of the PS in H were intermittent. Sedated P were younger than non-sedated. Only 7 P received PS after asking for euthanasia. The most used medication was midazolam. Conclusions: This study reveals a first insight into the use and practice of PS in German PCU and H. For a more detailed systematic survey into the course of decision-making and procedures, a new complementary optional module on PS is being developed by the HOPE group
