The antenna array asynchronous interference cancellation problem is addressed by means of semiblind algorithms with projections to the nite alphabet. It is observed that the conventional Least Squares (LS) solution estimated over the training interval may not be suitable for initialization of the iterative semi-blind schemes in the case of asynchronous interference. The simulation results in an...

Transient simulation of electric network with non – zero initial values could be quite challenging even in frequency domain, especially when transient equation formulation involves vectorial sense establishment of the initialization effect of the storage elements. In this paper, we derived a robust laplace frequency transient mesh equation which takes care of the vectorial sense of these initia...

A recent framework for chosen IV statistical distinguishing analysis of stream ciphers is exploited and formalized to provide new methods for key recovery attacks. As an application, a key recovery attack on simplified versions of two eSTREAM Phase 3 candidates is given: For Grain-128 with IV initialization reduced to up to 180 of its 256 iterations, and for Trivium with IV initialization reduc...

The need for a preliminary assessment of the clustering tendency or clusterability of massive data sets is known. A good clusterability detection method should serve to influence a decision as to whether to cluster at all, as well as provide useful seed input to a chosen clustering algorithm. We present a framework for the definition of the clusterability of a data set from a distance-based per...

In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction err...

Wedefine an automaton-based abstract interpretation of a trace semanticswhich identifies loops that definitely initialize all elements of an array to values satisfying a given property, a useful piece of information for the static analysis of Java-like languages. This results in a completely automatic and efficient analysis, that does not use manual code annotations. We give a formal proof of c...

Model based coding is a promising very low bit rate video coding technique. The idea behind model-based coding is to parameterize a talking head, and then to extract and transmit the parameters describing the facial movements, such as the facial expressions and the head motion to the receiver. At the receiver, the parameters are used to control face animation in order to reconstruct the talking...

Object-oriented class-based languages provide mechanisms for the initialization of newly-created objects. These mechanisms specify how an object is initialized and what information is needed to do so. The initialization protocol is usually implemented as a list of constructors. It is often the case that the initialization protocol concerns some orthogonal properties of objects. Unfortunately, i...
