Consistency relations are often used to design residual generators based on nonlinear process models. A main difficulty is that they generally include time differentiated versions of known signals which are difficult to estimate in a noisy environment. The main results of this paper show how to lower, or if possible avoid, the need to estimate derivatives of known signals in order to compute a ...

This work addresses three problems with reinforcement learning and adap-tive neuro-control: 1. Non-Markovian interfaces between learner and environment. 2. On-line learning based on system realization. 3. Vector-valued adaptive critics. An algorithm is described which is based on system realization and on two interacting fully recurrent continually running networks which may learn in parallel. ...

Support Vector Machine based on Time Series (SVM-TS) was applied to predict soil moisture and nitrate nitrogen (NO3--N) content. For the prediction of soil moisture, the statistical result (t-test) indicate that there is no obvious difference between predicted and observed values in 0-20cm and 20-60cm soil layers, and that SVM-TS is capable for soil moisture prediction. For the prediction of NO...

I discuss vacuum alignment and CP violation in technicolor theories of electroweak and flavor symmetry breaking. I review the surprising appearance of rational phase solutions in the technifermion sector and propose a new solution of the strong CP problem of quarks. I then discuss the sources of weak CP violation, in both the CKM matrix and the suppressed extended technicolor and topcolor–assis...

What is the purpose of taking norms and norm practices as primary unit of analysis for the investigation of socio-economic transformation? In the first instance, socio-economic change is driven by institutional (i.e. rule) changes and rules are made by economic actors: Codified institutions are established by the legislative authorities, generally the government, and implemented by an executive...

Realising business value and identifying the benefits arising from implementations of ERP systems remains a significant challenge for both research and practice. A review of existing work on ERP benefits reveals that current frameworks pay limited attention to contextual and temporal variations; socio-technical and business change; and levels of benefit realisation. This paper presents findings...

A disordered spin glass model where both static and dynamical properties depend on macroscopic magnetizations is presented. These magnetizations interact via random couplings and, therefore, the typical quenched realization of the system exhibit a macroscopic frustration. The model is solved by using a revisited replica approach, and the broken symmetry solution turns out to coincide with the s...

Consider times series data like that displayed on the right Why shouldn't it be modeled as a regression of the dependent variable on the time variable? The regression (i.e. curve-fitting) model would analyze the data into two parts. The first is called the explained part, which is the part of the dependent variable that is captured as a function of the independent variable, which would be time ...

A new method for performing a balanced reduction of a high-order linear system is presented. The technique combines the proper orthogonal decomposition and concepts from balanced realization theory. The method of snapshots is used to obtain low-rank, reduced-rangeapproximationsto the system controllabilityand observability grammiansin either the timeor frequency domain.The approximationsare the...

If a malicious party can insert a self-issued CA public key into the list of root public keys stored in a PC, then this party could potentially do considerable harm to that PC. In this paper, we present a way to achieve such an attack for the Internet Explorer web browser root key store, which avoids attracting the user’s attention. A realisation of this attack is also described. Finally, count...
