Integrated Analysis of Vertical Alignments and Speed Profiles for Rail Transit Routes (Civil Project)

Frequent accelerations and decelerations for rail transit trains adversely affect in the major performance measures of travel time, tractive energy consumption and braking wear between stations. A dipped vertical alignment between rail transit stations provides trains some added advantages from gravity in accelerating as well as in decelerating. A deterministic simulation model based on basic kinematics and resistance relations has […]

Competitive Global Ports for Regional Economic Development: The Port of Valencia

Face to high unemployment and GDP stagnation, competitive ports bear potential positive impacts on regional economic development over their hinterland. Ports are conceived as nodes in global supply chains basing their competitiveness in deriving location, infrastructure, connectivity and supply chain integration advantages for logistics operators. In the current global logistics scenario, port oversupply has increased competition, and global shipping companies […]

System Identification of Irrigation Channels with Overshot and Undershot Gates (Civil Project)

Water resources in Australia are limited. For a farmer the access to water is crucial and due to the dry climate the farmers in Australia can not rely on precipitation. Irrigation is therefore a very important part of the farming industry. The Coleambally Irrigation Area is situated in the southern parts of New South Wales close to the border of […]

Analysis and Performance Measurement of Construction Logistics

The construction industry is a business with an intense flow of both material and information that require well-functioning logistics in order to not suffer from unnecessarily high costs. Suppliers play a big part regarding the costs of the distribution and handling of material and due to this a construction project’s costs are affected a great deal by the suppliers’ actions. […]

Sustainable Low-Cost Housing in Ethiopia: A Study of CSSB-Technology (Civil Project)

This degree project is about sustainable low-cost housing in Ethiopia with a focus on CSSB-technology, which is one method of constructing houses. The project allowed me to visit Ethiopia during seven weeks in 2010, to observe, gather information and to perform tests regarding the specific subject. It is a sub-project to a larger research project initiated in 2002 at Halmstad […]

Behaviour and Structural Design of Concrete Structures Exposed to Fire (Civil Project)

Concrete has an excellent intrinsic behaviour when exposed to fire, especially when compared to other building materials. However, its fire resistance should not be taken for granted and a proper structural fire design is certainly necessary. This design is based on the understanding of both the material and the structural behaviour of concrete exposed to fire. A number of complex […]

The Impact of BIM/VDC on ROI: Developing a Financial Model for Savings and ROI Calculation of Construction Projects (Civil Project)

Building Information Modeling (BIM) or Virtual Design and Construction (VDC) recently has been regarded as crucial by the architecture, engineering, and construction (AEC) industry. The use of BIM/VDC represents the creation and use of a three-dimensional (3D) virtual model that amplifies the design, construction, and operation of a building. This technological improvement fundamentally changes the process of how the buildings […]

Public Private Partnerships: as a Public Infrastructure Optimizer (Civil Project)

A public private partnership is an alternative to procurement of the facility by the public sector, using funding from tax revenues or public borrowing. In a typical public sector procurement, the public authority sets out the specifications and design of the facility, calls for bids on the basis if this detailed design, and pays for construction of the facility by […]

Separate Treatment of Wash Water From Sand Filter Using Disc Filter Technology (Civil Project)

The purpose of this study is to evaluate the convenience and effectiveness of using a disc filter to treat washing water from the sand filters at Sundet wastewater treatment plant. The disc filter is used aiming for the reduction of suspended solids and phosphorus. The study was divided in two main experimental stages. During the first stage laboratory jar-tests were […]

Planning Forest Routes for Silvicultural activities using GIS based Techniques (Civil Project)

Forests are natural resources that provide essential services for different groups of users from human beings to native habitats. They are actually home of diverse range of biological groups; contribute to alleviate climate change through sinking carbon-dioxide from the atmosphere and supplying oxygen back to it and finally they are regarded as wood resources by human beings. In recent decades, […]
