— This paper explores designs for the implementation of high sensitivity accelerometers based on Fabry-Pérot Interferometers. Although such structures have the potential to achieve µg resolutions, design and implementation challenges can be limiting. This paper discusses the creation of such devices using two distinct proof mass and optical designs: one of(More)
TANGO 1 is an object oriented control system toolkit based on CORBA 2 presently under development at the ESRF. In this paper, the TANGO philosophy is briefly presented. All the existing tools developed around TANGO will also be presented. This includes a code generator, a WEB interface to TANGO objects, an administration tool and an interface to LabView.(More)
A reservation based medium access control (MAC) protocol has been adopted by the IEEE 802.16 standard as the basic protocol for data communication within the upstream channel. In this paper, we propose the following five new contention slot allocators (CSA) for the IEEE 802.16 MAC protocol: Forced-CSA, Variable-CSA, Multicast-CSA, Collision Free-CSA and(More)
We report the design, fabrication, and characterization of a new system that combines the performances of two different types of magnetic characterization systems, Alternating Gradient Force Magnetometers (AGFM) and susceptometers. The flexibility of our system is demonstrated by its capability to be used as any of them, AGFM or susceptometer, without any(More)
The ESRF control system is in the process of being mod-ernised. The present control system is based on VME, The main frontend operating system will be GNU/Linux running on Intel/x86 and Motorola/68k. Linux will also be used on handheld devices for mobile control. This poster describes how GNU/Linux is being used to modernise the control system and what(More)
Yeasts play a central role in the wine making process. To study the yeasts in a stable environment and physiological state, a Multi-Stage Continuous Fermentor (MSCF) has been designed that mimics steps of the batch fermentation process. In this paper, the problem of the control of the sugar concentrations in each of the four reactors of the MSCF is(More)
