Tai Tam Tuk reservoir dam in Hong Kong: historical background and site selection
No full textSince 1842, the Hong Kong Colonial Government had been plagued with a perennial problem of deficiency in fresh water provision for an ever-growing population. A long-term solution to this was the commencement of Tai Tam Waterworks Scheme on Hong Kong Island; with Tai Tam Tuk Reservoir Dam constructed between 1912 and 1917 being its largest and latest addition. This study drew its inspiration from a field trip during which the research team encountered several peculiar brick wells at Tai Tam Habour. Driven by curiosity to learn their actual function, the team gleaned bits and pieces of archives scattered in Hong Kong and London, followed by in-depth interviews with senior residents nearby and a field study cum diving expedition in search of the remnants associated with the dam construction. Years of extensive research has paid off, and led to the unveiling of the wells’ interlocking history with Tai Tam Tuk Reservoir. The findings contribute to a better understanding of Tai Tam Tuk Reservoir Dam through a reconstruction of its history and an analysis of its site investigation process. The century-old remains of ground investigation constitute an illuminating testament to Hong Kong’s waterworks for engineers to understand time-tested engineering methodology

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

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
