Requirements to Testing of Power System Services Provided by DER Units

The present report forms the Project Deliverable ‘D 2.2’ of the DERlab NoE project, supported by the EC under Contract No. SES6-CT-518299 NoE DERlab. The present document discuss the power system services that may be provided from DER units and the related methods to test the services actually provided, both at component level and at system level

Evaluation of key positions and employees management level in manufacturing industry - The Czech case

Human resources management, especially the key employees management, has fundamental influence on companies' sustainable business, which has to be considered as the priority of any business functioning. The aim of this paper is to evaluate current level of the key positions and employees management in the Czech business environment and to propose a process of its effective implementation and application in practice. Online questionnaire survey was provided using 105 companies operating in manufacturing industry of the Moravian-Silesian region as the sample. Statistical methods of data analysis were used. Fisher exact test, coefficients Phi and Cramer's V were counted to test relations between variables. The survey results include an evaluation of the present situation as it comes to the use of the key positions and employees management system as well as an identification of interests in new system implementation. There was a low rate of use of given system in these business, with two thirds of companies showing an interest in implementing the new system. The process of implementation and the use of the key positions and employees in practice was proposed. The process is suggested in the way to make its content and form be a certain guide and help for companies to realize particular activities of this process. It would contribute to the successful realization of complex and systematic approach towards the work with the key positions and employees.Web of Science121art. no. 24

On the Integrated Surface Uplift for Dip‐Slip Faults

Interferometric Synthetic Aperture Radar observations often provide maps of vertical displacement that can be integrated to estimate an uplift volume. Relating this measure to source processes requires a model of the deformation. Bignami et al. (2019) argue that the negative uplift volume associated with the 2016 Amatrice–Norcia, central Italy, earthquake sequence requires a coseismic volume collapse of the hanging wall. Using results for dip‐slip dislocations in an elastic half‐space we show that V_(uplift)=(P/4)(1−2ν)sin(2δ) in which P is the seismic potency, ν is the Poisson’s ratio, and δ is the fault dip, consistent with an earlier result of Ward (1986). For reasonable estimates of net potency for the 2016 Amatrice–Norcia sequence, this simple formula yields uplift volume estimates close to that observed. We conclude that the data are completely consistent with elastic dislocation theory and do not require a volume collapse at depth

Three simple steps for improving diagnostic accuracy in hypertension

This abbreviated assessment may lead to inaccurate classification, unnecessary treatment and dilution in treatment benefit for the population. We aimed to explore how accurate current methods are in diagnosing mild hypertension, and to explore practical methods of improving targeting of antihypertensive treatment using clinic visits but without lengthy observation. Material and methods: We applied current diagnostic methods to 3965 individuals with mild hypertension who were followed for a year in the placebo arm of the MRC Mild Hypertension Trial (Medical Research Council). We thus calculated the proportion selected for treatment by current methods and the diagnostic accuracy, using average blood pressure beyond six months as representing "true" long-term blood pressure. We looked at the benefit of averaging blood pressures, prolonging observation modestly and estimating within-person blood pressure variability. Results: Prolonging observation to three months selects a smaller (by about 12%) proportion of the sample for treatment. At three months the proportion of the sample selected is similar to the proportion defined as "truly" hypertensive. The diagnostic accuracy of current methods is poor with up to 69% discrepancy in classification. This discrepancy was improved in absolute terms by up to 18% by prolonging observation to three months and using average blood pressures. Identifying those individuals with low within-person variability allows marked improvement in the prediction of "true" hypertension. Conclusion: Although some inaccuracy in the diagnosis of hypertension is inevitable, observation for three months, averaging blood pressures and estimating within-person blood pressure variability can markedly improve upon current methods used for targeting antihypertensive treatment.Tilgangur: Flestir sem greindir hafa verið með háþrýsting hafa fengið greininguna eftir þrjár eða færri mælingar á blóðþrýstingi hjá lækni. Þetta skyndimat gæti leitt til ónákvæmni í greiningu, ónauðsynlegrar meðhöndlunar og minni meðferðarávinnings en efni standa til. Við höfum reynt að meta hversu nákvæm greining fæst með hefðbundnum aðferðum og skoðað hagnýt ráð sem beita mætti til þess að bæta öryggi greiningarinnar án þess að seinka greiningu um of. Efniviður og aðferðir: 3965 manns var fylgt eftir í lyfleysuhluta "MRC Mild Hypertension Trial" (Medical Research Council). Hlutfall hópsins sem myndi hafa valist til meðferðar samkvæmt algengum klínískum vinnubrögðum var metið og einnig var reynt að áætla nákvæmni þeirrar greiningar með samanburði við meðalþrýsting eftir meira en sex mánaða eftirfylgni sem var talið ígildi raunverulegs langtímablóðþrýstings. Við litum á kosti þess að nota meðalþrýsting nokkurra heimsókna, eftirlit og bið í tiltölulega skamman tíma (þrjá mánuði) og áhrif þess að taka tillit til breytileika blóðþrýstings hvers einstaklings. Niðurstöður: Greining háþrýstings eftir þriggja mánaða eftirlit fremur en eftir þrjár mælingar minnkar hópinn sem talinn er hafa háþrýsting um næstum 12%. Ekki virtist ávinningur af því að lengja eftirlitið frekar. Greining háþrýstings samkvæmt þeim hefðbundnu vinnubrögðum sem oftast er beitt núna er ónákvæm og leiðir hugsanlega til rangrar greiningar hjá allt að 69% einstaklinga. Ónákvæmnina má minnka um allt að 18% með því að bíða með greiningu í þrjá mánuði og með því að nota meðalblóðþrýsting nokkurra heimsókna. Auðveldara reynist að spá fyrir um raunverulegan langtímablóðþrýsting með því að leggja mat á breytileika blóðþrýstings. Ályktun: Nokkur ónákvæmni í greiningu háþrýstings er óhjákvæmileg en auka má verulega öryggi greiningarinnar með því að fylgja fólki eftir í þrjá mánuði, nota meðalblóðþrýsting og leggja mat á breytileika blóðþrýstings hvers og eins
