Modeling and Analysis of a Direct Time-of-Flight Sensor Architecture for LiDAR Applications

Edoardo Charbon, Chunmin Zhang, Preethi Padmanabhan

Direct time-of-flight (DTOF) is a prominent depth sensing method in light detection and ranging (LiDAR) applications. Single-photon avalanche diode (SPAD) arrays integrated in DTOF sensors have demonstrated excellent ranging and 3D imaging capabilities, ma ...

Self-Tracking Solar Concentrator Device

Jacques-Edouard Moser, Christophe Moser, Volker Günter Zagolla

A device for self-tracking a light source, including a focusing optical device configured to focus incoming light to a focal spot, an adaptive device configured to reflect the light of the focal spot and arranged to provide for a phase change at an area of ...

Modelling of the receiver transient flux distribution due to cloud passages on a solar tower thermal power plant

Daniel Favrat, Germain Augsburger

As more and more solar tower thermal power plants are being operated, built or planned, effort is put both on the development and research to bring costs down and increase the plant efficiency. In those plants, the central receiver is one of the key compon ...

Thermo-economic optimisation of large solar tower power plants

Germain Augsburger

Given the growing number of solar tower power plants in operation, under construction and under planning, the assessment and the optimisation of their performance are required both at the energy level and the economic level. In other words, the same way as ...

Influences of polymer concrete surfacing and localised load distribution on behaviour up to failure of an orthotropic FRP bridge deck

Thomas Keller, Wendel Michael Sebastian

This paper presents experimental results which demonstrate the important, but to date little-studied influence of surfacing on the response up to failure of orthotropic GFRP bridge decking local to concentrated loading. Four bonded deck specimens were test ...

From Single- to Multi-Tower Solar Thermal Power Plants: Investigation of the Thermo-Economic Optimum Transition Size

Daniel Favrat, Germain Augsburger

When considering very large single-tower heliostat fields, the attenuation and spillage losses are growing with the distance to the central receiver. Therefore multi-tower configurations are modelled and investigated to find the thermo-economic optimal siz ...

Utilization of Direct and Diffuse Sunlight in a Dye-Sensitized Solar Cell - Silicon Photovoltaic Hybrid Concentrator System

Michael Graetzel, Shaik Mohammed Zakeeruddin, Paul Liska

The concept of a tandem hybrid concentrator solar module was demonstrated from a dye-sensitized TiO2 solar cell (DSSCs) and a silicon p-n junction solar cell. The test system employed DSSC and Si cells with indoor AM1.5G efficiencies of 9.1 and 18.1%, resp ...

A daylighting knowledge-base for performance-driven facade design exploration

Marilyne Andersen

Heuristics and simple design guides are important tools for designers who wish to incorporate daylighting into the early design process. This paper describes a simulation-based method for generating simple rules for facade design, based on specific climate ...

Thermo-economic Optimisation of the Heliostat Field of Solar Tower Thermal Power Plants

Daniel Favrat, Germain Augsburger

A method of optimising the thermodynamic and economic performance of heliostat field within a solar tower thermal power plant has been developed. The method includes the generation of a heliostat field given a set of design variables, the assessment of its ...
