Linear quadratic optimization problem of discrete time feedback systems with constrained feedback information flow is studied. Two cases of non-structural and structural feedback constraints are considered and corresponding optimal system synthesis procedures are derived. The approach presents a general solution to the problem of feasibleoptimal decentralized control systems synthesis with state feedbacks.

A problem of learning with a probabilistic teacher is considered. Neither prior class probabilities nor class densities are assumed to be known and pattern recognition procedures are derived from nonparametric density and regression estimates. Weak and strong Bayes risk consistency of the procedures is shown. Examples of procedures using the kernel, the nearest neighbor and the orthogonal series estimates are given.

Automotive control has developed over the decades from an auxiliary te- nology to a key element without which the actual performances, emission, safety and consumption targets could not be met. Accordingly, automotive control has been increasing its authority and responsibility – at the price of complexity and di?cult tuning. The progressive evolution has been mainly ledby speci?capplicationsandshorttermtargets,withthe consequencethat automotive control is to a very large extent more heuristic than systematic. Product requirements are still increasing and new challenges are coming from potentially huge markets like India and China, and against this ba- ground there is wide consensus both in the industry and academia that the current state is not satisfactory. Model-based control could be an approach to improve performance while reducing development and tuning times and possibly costs. Model predictive control is a kind of model-based control design approach which has experienced a growing success since the middle of the 1980s for “slow” complex plants, in particular of the chemical and process industry. In the last decades, severaldevelopments haveallowedusing these methods also for “fast”systemsandthis hassupporteda growinginterestinitsusealsofor automotive applications, with several promising results reported. Still there is no consensus on whether model predictive control with its high requi- ments on model quality and on computational power is a sensible choice for automotive control.
A novel magnetically levitated work piece table has been designed. This device is able to perform linear and rotational motions in four axes with high accuracy, so that different operations can be run on the work piec...

This report summarizes the practical requirements for siting radio direction finders operating in the 3 to 30 mc range and is intended primarily for the use of personnel responsible for site selection and DF antenna installation on Naval ships. The effects of reradiation from the ship's superstructure on direction finder performance are described. By the use of specific examples of shipboard installations, the merits of various siting compromises are discussed.
