Dye-sensitized solar cells (DSC) are based on molecular and nanometer-scale components. Record cell efficiencies of 12%, promising stability data and means of energy-efficient production methods have been accomplished. As selling points for the DSC technol ...
An electroplated copper substrate was evaluated for heat dissipation in 1.55-μm optically pumped vertical extended cavity surface emitting lasers (OP-VECSELs). It is a cost-effective and flexible solution compared with the previously proposed chemical vapo ...
Hydropeaking is a common phenomenon of water courses that are affected by peak energy production of hydro power plants. It may cause severe impacts on the biodiversity of a stream. In fact, due to hydropeaking fishes, macroinvertebrates and aquatic plants ...
Environmental labelling is an accountability mechanism for firms to satisfy growing demands to prove that value chains are sustainably managed. Although the large variety of ecolabels available today can be interpreted as a sign of their success, it is ove ...
Flood management is more than ever an issue for dam designers and engineering consulting firms in charge of rehabilitation works. Piano Key Weirs are a new cost-effective type of spillway designed to improve dams discharge capacity. These structures are pa ...
The design of low-cost and low-power optical transducers on plastic foil for colorimetric gas sensors is proposed. The transducer was fabricated from PET or PEN foil on which polymeric micro-mirrors and colorimetric film were patterned using additive techn ...
This thesis presents three economic perspectives to moving forward a global climate agreement for post-2012. The first part develops a grading system for assessing thirteen proposals for post-2012 climate policy. The grades are based on four criteria: envi ...
Computational reputation-based trust models using statistical learning have been intensively studied for distributed systems where peers behave maliciously. However practical applications of such models in environments with both malicious and rational beha ...
The motivation for this project is to prevent optical cross-talk in an optical sensor array, named ommatidia and fabricated in the CURVACE project. The goals of the project are to show that Micromoulding in Capillaries (or MIMIC) is a very effective and co ...
This research was motivated by our interest in understanding the criteria for measuring the success of a recommender system from users’ point view. Even though existing work has suggested a wide range of criteria, the consistency and validity of the combin ...
