Although LEP was designed to allow both betatron and synchrotron injection, only betatron accumulation has been used up to now. During 1994 tests were made of injection in synchrotron phase space. Results are presented from these machine studies which show that for both 4 bunch and 8 bunch pretzel injection, this form of injection is a more efficient way of accumulating LEP beams. The use of sy...

This paper proposes CMOS LC-tank divide-by-3 injection locked frequency dividers (ILFDs) fabricated in 0.18 μm and 90nm CMOS process and describes the circuit design, operation principle and measurement results of the ILFDs. The ILFDs use two injection series-MOSFETs across the LC resonator and a differential injection signal is applied to the gates of injection MOSFETs. The direct-injection di...

At Hohenpeissenberg (47◦48′N, 11◦07′ E, 988 m asl), a rural site 200 300 m higher than the surrounding terrain, sulphuric acid concentrations, particle size distributions, and other trace gas concentrations were measured over a two and a half year period. Measured particle number concentrations and inferred particle surface area concen5 trations were compared with box-model simulations based on...

Sequential injection systems for wine analysis have been developed in recent years for determination of more than 20 species. Several aspects of these systems are reviewed in the present paper. Special focus is given to implementation of in-line sample treatment and adaptation of system operation through software control to enable determination in different types of wine. The strategies used to...

An optical pulse injection locking technique is employed to generate shorter pulses from a passively modelocked quantum dot laser. The optical pulse injection locking enables the coherent addition of phaselocked longitudinal mode groups from two separate modelocked lasers without the use of stabilisation control loops, thus increasing the spectral bandwidth output resulting in optical pulses wi...

In this paper, we introduce a framework for learning biped locomotion using dynamical movement primitives based on non-linear oscillators. Our ultimate goal is to establish a design principle of a controller in order to achieve natural human-like locomotion. We suggest dynamical movement primitives as a central pattern generator (CPG) of a biped robot, an approach we have previously proposed fo...
