The regiochemically flexible functionalization of fluoro-and trifluoromethyl-substituted indoles

The use of organometallic reagents for functionalization of arenes and heterocycles has recently been renewed by our group. The use of bulky trialkylsilyl groups allows one to shield an acidic position by steric hindrance and the introduction of a chlorine ...

A collaborative platform for sustainable building design based on model integration over the internet

Céline Weber

Considerable potential exists for reducing life cycle environmental impacts of buildings in Japan. While energy consumption during the operation stage of a building's lifetime is usually dominant, indirect energy use and pollutant emissions associated with ...

Evaluation of a building using the emergy method

Emergy (spelled with an m) is the energy of one kind, usually solar energy, which is required to make a service or product. The yearly emergy consumption/production of a building is evaluated considering the Solar Energy Laboratory (LESO) building on the c ...

Auto-zero differential difference amplifier

Maher Kayal

The differential difference amplifier (DDA) is considered as a versatile building block for the analogue processing of floating voltages. An automatic offset compensation scheme is proposed for the DDA structure. A digital successive approximation algorith ...

Effect of compressive loads on the tensile strength of concrete at high strain rates

Eugen Brühwiler

This paper describes the behaviour of concrete subjected to tensile loads at high strain rates with and without compressive load histories. The tests, carried out at the laboratory of building materials of the Swiss Federal Institute of Technology, Zurich, ...
