CDF and DØ detectors have already collected 1.3 fb−1 of data delivered by the Tevatron collider at 1.96 TeV center-of-mass energy. We present here the various analyses that are currently testing the possibility of a supersymmetric extension of the Standard Model. No evidence for such processes have been found in luminosities that range from 300 to 800 pb−1 and different limits on the different ...

Conventional work on scienti c discovery such as BACON derives empirical law equations from experimental data. In recent years, SDS introducing mathematical admissibility constraints has been proposed to discover rst principle based law equations, and it has been further extended to discover law equations from passively observed data. Furthermore, SSF has been proposed to discover the structure...

Econometric busines cycle research (EBCR) combines economic theory and measurement in the study of business cycles, i.e., up and downs in overall economic activity. EBCR has four goals: description, forecasting, policy evaluation and implementation/testing of economic theories. In this paper I assess four EBCR methods: business cycle indicators, simultaneous equations models, vector autoregress...

Offshore wind turbines are considered as an important element of the future energy infrastructure. There is currently a surge in the construction of such facilities in Europe, yet there is no track record of long-term performance of these structures. Offshore wind turbines are dynamically sensitive structures because of the very nature of the structural form (tall and slender) and the different...

We demonstrate a new method for extracting high-level scene information from the type of data available from simultaneous localisation and mapping systems. We model the scene with a collection of primitives (such as bounded planes), and make explicit use of both visible and occluded points in order to refine the model. Since our formulation allows for different kinds of primitives and an arbitr...

In this paper we consider the problem of creating a two dimensional spatial representation of gas distribution with a mobile robot. In contrast to previous approaches to the problem of gas distribution mapping (GDM) we do not assume that the robot has perfect knowledge about its position. Instead we develop a probabilistic framework for simultaneous localisation and occupancy and gas distributi...

In this note we study the problem of simultaneous stabilization for the algebra AR(D). Invertible pairs (fj , gj), j = 1, . . . , n, in a commutative unital algebra are called simultaneously stabilizable if there exists a pair (α, β) of elements such that αfj + βgj is invertible in this algebra for j = 1, . . . , n. For n = 2, the simultaneous stabilization problem admits a positive solution fo...

The control function approach (Heckman and Robb (1985)) in a system of linear simultaneous equations provides a convenient procedure to estimate one of the functions in the system using reduced form residuals from the other functions as additional regressors. The conditions on the structural system under which this procedure can be used in nonlinear and nonparametric simultaneous equations has ...
