In this document the final outcomes of the analysis on rework events in construction projects of Grupo Williams (GW) are shown. The intention of the study has been formulated as: To assess rework costs in construction projects of Grupo Williams and recommend improvements to cut back these rework costs. The assessment was done through analysis of realized projects.
A lot of lakes, coastal zones and oceans are directly or indirectly influenced by human activities. Through the outlet of a large amount of materials in the air and water, we’re changing the natural conditions on local and international levels. Remote sensing sensors, on satellites or planes, can easily acquire image data, offering the user with details about the indicated region, object or phenomenon. Three unique programs are outlined within this dissertation.
This report is conducted together with NCC Construction Sverige AB and treats sewers from the contractors’ viewpoint. The report investigates in an overall way how the work with sewers operates in a contract company and which aspects that speak for the different pipe materials, plastics and concrete from an overall economic perspective. Presently both tubes and wells created from plastic as well as concrete are utilized and promoted. The document represents which aspects that affect the option of pipe system, plastics or concrete.
This project aims to improve our understanding of how dams and reservoirs impact freshwater systems worldwide. The following questions were addressed specifically: 1) what are the spatial patterns and magnitudes of flow regulation and channel fragmentation by dams globally; 2) how are
The European Union Water Framework Directive (WFD), with initiatives to manage surface water resources, has increased the need for fast and inexpensive methods for monitoring conditions in streams. The objective of this thesis is to assess the potential of near-infrared spectroscopy (NIRS)
This research addresses the problem of modeling time-dependent traffic flow with real-time traffic sensor data for the purpose of online traffic estimation and prediction to support ATMS/ATIS in an urban transportation network. The fundamental objectives of this study are to formulate and
Title: An Integrated Optimal Control System for Emergency Evacuation How to effectively control evacuation traffic has emerged as one of the critical research issues in transportation community, due to the unusually high demand surge and the often limited network capacity. This dissertation
In this thesis permanent magnet direct drive generator for power conversion from water currents is studied. Water currents as a power source involves a number of constrains as well as possibilities, especially when direct drive and permanent magnets are considered. The high
In the past decade significant advances have been made in the field of high performance concretes. The next generation of concrete, Ultra-High Performance Concrete (UHPC), exhibits exceptional strength and durability characteristics that make it well suited for use in highway bridge structures…
The purpose of this study is to investigate the representation of driver behavior under extreme conditions, towards development of a micro-simulation modeling framework of traffic flow to support evaluation of management strategies and measures in emergency situations. To accomplish this objective, particular
