A non-feedback multiphase clock generator using direct interpolation

This paper presents a new multiphase clock generator using direct interpolators. No feedback loop is required. A single-stage direct interpolation architecture is proposed. A 1/4 frequency divider and a short-circuit current suppression interpolator are developed to achieve the precise interpolation. The circuit was fabricated in a standard 0.35μm, 3.3V CMOS process. The multiphase clock generator

Ecotoxicological assessment by microcosm tests on plankton communities

The aim of this thesis is to present a short-term plankton community toxicity test in laboratory microcosms, with which the effect of the test substance on species abundance and composition of the community is evaluated. This laboratory microcosm is an intermediate between single-species tests and outdoor mesocosm tests. The brominated flame retardant HBCDD was chosen as the reoccurring test subst

Adaptive Control (2 ed.)

Introduces theoretical and practical aspects of adaptive control. Starting with a broad overview, the text explores real-time estimation, self-tuning regulators and model-reference adaptive systems, stochastic adaptive control, and automatic tuning of regulators. Additional topics include gain scheduling, robust high-gain control and self-oscillating controllers, and suggestions for implementing a

Dynamic Thermal Modeling and Application of Electrical Machine in Hybrid Drives

This paper presents a holistic view of thermal modeling for an electrical machine used in a Hybrid Electrical Vehicle (HEV). This interconnected system model focuses on the thermal assessment of an electrical machine in a HEV application and estimates the time to failure of the machine depending on the construction of the insulation system and the exploitation of the machine. A transient thermal m

A Method for Finding the Maximal Set in Excess Demand

We present a polynomial time method for identifying the maximal set in excess demand at a given payoff vector. This set can be used in "large" partnership formation problems to identify the minimum element in the set of individually rational payoff vectors at which there is no overdemanded set of agents. This minimum element corresponds to the minimum Walrasian equilibrium price vector in a specia

Fragmentation of molecules and clusters after resonant excitation of core electrons

A study highlighting several aspects of resonant spectroscopies where fragmentation processes are investigated is described. We focus primarily on understanding the dynamical processes taking place in core-excited states in molecules. An example where fast dissociation and molecular alignment are discussed is given for the ammonia molecule.
