Schafer, D., Squier, J.A., Maarseveen, J. Van, Bonn, D., Bonn, M., Müller, M.
In situ quantitative imaging of concentration profiles of reactants and products inside a microfluidic reactor is achieved, with submicron spatial resolution with similar to mM sensitivity and on...
Hodder, A., Simond, J.-J., Sapin, A., Schafer, D.
Nowadays, multilevel VSIs (Voltage Source Inverter) begin to be widely used in middle and high power installations such as variable speed drives, FACTS (Flexible AC Transmission System) and...
Synchronous machines parameters determination using finite elements method. (2000)
Ramirez, C., Tu Xuan, M., Simond, J.-J., Schafer, D., Stephan, C.-E.
The paper deals with the determination of synchronous machine parameters using a 2D Finite Element Method – FEM (Flux2D- Cedrat). Simulations of no-load sudden three phase short- circuits are...
Doubly-Fed Asynchronous Machine with 3-Level VSI cascade for Variable Speed Pump Storage. (2000)
Sapin, A., Hodder, A., Schafer, D., Simond, J.-J.
This paper deals with a fixed-frequency variable-speed motor/generator with 3-level VSI (Voltage Source Inverter) cascade. The 3-level VSI is applied to a DASM (Doubly-fed ASynchronous Machine) for...
Expected benefits of adjustable speed pumped storage in the European network. (1999)
Simond, J.-J., Sapin, A., Schafer, D
In the context of a sustainable development the optimal use of the electrical energy will require advanced networks allowing interconnections on very long distances and addressing the storage...
Schafer, D., Simond, J.-J.
The use of a static frequency converter which is inserted between the grid and the stator is a well known solution to achieve an adjustable speed machine. Adjustable speed drive systems have already...

Optimized Design on Variable-Speed Drives Based on Numerical Simulation. (1997)
Simond, J.-J., Sapin, A., Kawkabani, B., Schafer, D., Xuan, M. Tu, Willy, B.
The proposed paper describes the modelling and the prediction of the steady- state or transient behaviour of different modern variable-speed drives. The necessity of a performant numerical simulation...
Ethics and reproductive medicine (1996)
Schafer, D, Baumann, R, Kettner, M
This article surveys relevant moral and ethical implications of reproductive medicine, excluding any aspects of contraception. To maintain the methodological priority of a moral perspective, it...
Cunningham, D, Schafer, D, Tanenbaum, S W, Flashner, M
Cytochalasin A at 5 to 25 microgram/ml (1.0 x 10(-5) to 5.2 x 10(-5) M) inhibited the growth of three gram-positive bacteria, Arthrobacter sialophilus, Staphyloccus aureus, and Bacillus...
Induction and regulation of neuraminidase synthesis in Arthrobacter sialophilus.
Wang, P, Schafer, D, Miller, C A, Tanenbaum, S W, Flashner, M
A variety of N-acetylneuraminic acid (AcNeu) derivatives and analogs were examined as inducers of the extracellular neuraminidase of Arthrobacter sialophilus. Neuraminidase inductions were primarily...
