A Constraining Hyperplane Technique for State Variable Constrained Optimal Control Techniques

A new approach to the numerical solution of optimal control problems with state-variable inequality constraints is presented. It is shown that the concept of constraining hyperplanes may be used to approximate the original problem with a problem where the constraints are of a mixed state-control variable type. The efficiency and the accuracy of the combination of constraining hyperplanes and a sec

The ergativity parameter

Within the field of syntactic typology, which seeks to describe and classify the range of grammatical phenomena extant in the world’s languages, one of the most important problems is whether or not a given language is ergative. Within a generative approach, a further problem is accounting for the existence of ergative languages by the definition of what may be termed an ‘ergativity parameter’. Thi

Enhancement of VCO Linearity and Phase Noise by Implementing Frequency Locked Loop

This paper investigates the on-chip implementation of a frequency locked loop (FLL) over a VCO that decreases the phase noise and linearizes the transfer function. Implementation of the FLL inside a PLL is also investigated and a possible application is highlighted. Design of a special kind of low noise frequency detector without a reference frequency (frequency-to-voltage converter), which is the

I gliporna blir allt synligt.

De mest långtgående avslöjandena om NSA:s verksamhet handlar inte längre om övervakning i egentlig mening. Inte heller är det avlyssning det rör sig om. Vad man verkar fokusera otroliga resurser på är ett slags direkt offensiva operationer som, alla såväl var för sig som sammantaget, syftar till att försvaga central teknisk infrastruktur.
