Dependence of unsaturated chloride diffusion on the pore structure in cementitious materials
No full textConceptual analysis is performed to examine the effects of pore features on the water continuity in unsaturated porous systems. The roles of pore features in relative chloride diffusion coefficient (Drc) of mortar specimens at various degrees of water saturation (Sw) were studied based on mercury intrusion porosimetry and resistivity tests. It is found that the role of pore structure in the Drc-Sw relationship is a result of its effect on the water continuity. Porosity and tortuosity are not relevant to the Drc-Sw relationship. A finer pore size distribution or lower pore connectivity tends to result in a lower Drc. The pore size effect on the Drc is pronounced primarily at high Sw, while the Drc is dominated by the pore connectivity at low Sw. Cement mortar with a higher water-to-binder ratio shows larger chloride diffusion at high relative humidity levels but smaller chloride diffusion at low relative humidity levels.Accepted Author ManuscriptMaterials and Environmen
Total Cost of Ownership for Application Replatform by Open-source SW
No full textAbstractIn intra-company IT environment, the use of open-source software (OSS) should be expanded to reduce IT costs and to establish SW governance. This requires the migration of systems from the existing commercial SW to open-source SW, but the attempt of application replatform is prevented by the expenses for application reprogramming and data migration. This study proposes a methodology for TCO calculation of application replatform using open-source SW. In practice, a five-year TCO shows a cost reduction effect of 78% - 83%. This TCO could be further reduced if the application size is increased due to data accumulation and the company gets open-source SW capabilities internally. In addition, it is possible to directly apply an application developed from open-source SW to a virtualized infrastructure environment, which enables to operate in a hybrid cloud environment. This enables a scalable, efficient and flexible IT operation and a sustainable TCO reduction in the futur
Water column, solid phase and porewater data in the Kiel Bight, SW Baltic Sea from 2016 to 2025

Water column oxygen concentrations were determined using oxygen sensors attached to the CTD framework. At selected water depths, water samples were collected with Niskin bottles for the analysis of nitrate concentrations using an autoanalyzer. Short sediment cores (<50cm) were recovered using a Multicorer (MUC), Minicorer (MIC) or Rumohrlot (RL). Bottom waters were sampled from the supernatant water in the sediment cores. Solid phase sediment samples were analyzed for total organic carbon using an element analyzer. Porewater was extracted from the sediment cores using rhizones and analyzed for total alkalinity (titration), ammonium (photometer), sulfate (ion chromatography), hydrogen sulfide (photometer), dissolved iron (ICP-OES) and dissolved manganese (ICP-OES). The collected data will be used to (i) determine the spatial and temporal variability of hydrogen sulfide in bottom waters of the Kiel Bight, (ii) identify the controlling factors governing the accumulation of hydrogen sulfide at the seafloor, and (iii) establish an early warning system of sulfidic seafloor conditions for regional stakeholders in the Baltic Sea
Crustal deformation in extensional regimes: Iceland, Nevada and SW Turkey
No full textIn 1991 a 23-point, 30 x 25 km, GPS geodetic network was established in the Hengill ridge-ridge-transform triple junction, SW Iceland. The GPS data were processed using the Bernese V3.2 software. The ambiguity-fixed solution yielded scaled formal errors of less than 1 cm in the horizontal and about 1 cm in the vertical. The effect of ocean loading on the vertical component of the GPS measurements, a hither-to ignored effect in GPS data, was examined and found to be negligible for surveys of this type. Extensional deformation processes in the western Basin and Range province were studied by analysing the co- and postseismic deformation associated with the 1954 Rainbow Mountain - Fairview Peak - Dixie Valley sequence of M>6.0 earthquakes. Levelling and triangulation data which constrain the coseismic deformation are fitted well by modelling uniform slip on rectangular planar dislocations embedded in an elastic half-space. The best-fitting fault geometries dip at 50 to 80 and extend to depths of 8 to 14 km. A simultaneous inversion of the triangulation and levelling data which spanned the coseismic period reveals that slip determined geodetically tends to be equal to, or greater than, the surface offsets. Using the single value decomposition method to invert the data allowed determination of where the coseismic slip was resolvable given the data distribution. The static stresses changes induced by each earthquake in the 1954 sequence were calculated using the source models derived from the geodetic modelling. After the first earthquake each event in the 1954 sequence was preceded by a static stress increase of 104 to 105 Pa. Thus, it appears that static stresses may have played an important role in triggering the later earthquakes. The vertical postseismic deformation which followed the earthquakes was modelled assuming stress redistribution in the Earth's crust through viscous flow in the lower crust. Calculation of surface deformation caused by the analastic response to a normal faulting earthquake was performed using the finite element method. The viscosity which best fit the postseismic levelling data was 1x10(^20) Pa s at depths of 10 to 30 km. GPS measurements made between 1988 and 1992 show that north-south aseismic extension within SW Turkey is occurring at rates of 11.7+5 mm/yr. The deformation extension was modelled along 2-dimensional north-south profiles using the finite element method. These calculations show that the postseismic deformation created by eight earthquakes of Ms6.5 and greater within SW Turkey this century accounts for 10% of the north-south extension rate measured by GPS. The rest can be explained as postseismic deformation from earthquakes in earlier centuries. Modelling indicates that north-south extension rates decrease from west to east across the province. Reoccupation of the GPS network in the year 2000 will yield a clear regional strain signal, given the errors of the 1989 survey

Change management of the SW projects in the small and medium business
No full textThe bachelor thesis focuses on SW projects, ways of their management and mainly change management in the small and medium business. This thesis is devided into two parts. Author deals with SW projects and most common mistakes during their development in the theory part. The main aim of this part is to refer to these mistakes the reader, who is interested in SW projects. Next, there is a comparision of the two famous methodics, which are well-known in the SW development. These are ITIL and RUP. Author will choose the one, which will be more acceptable for the Cleverdecision. At this time, Cleverdecision has no change management and every change during the SW development is managed by contracting condition. That is why author formulates the ways of change management in the practical part. This will be based on the chosen methodics from the theory part. This formulation is the main aim of this thesis. The contribution of the thesis is in the definition of the change management workflow and in the proposition of the templates for setting the change requests. These templates are sufficient for unification concepts and easier specification of the change requests. Insertion of the change management into the contract is part of the thesis as well
