Most training algorithms for HMMs assume that the whole batch of observation sequences is given ahead of time. This is particularly the case for the the standard EM algorithm. However, in many applications such as speech, the data is generated by a temporal process. Singer and Warmuth developed online updates for HMMs that process a single observation sequence in each update. In this paper we t...

A ow-directed inlining strategy uses information derived from control-ow analysis to specialize and inline procedures for functional and object-oriented languages. Since it uses control-ow analysis to identify candidate call sites, ow-directed inlining can inline procedures whose relationships to their call sites are not apparent. For instance, procedures deened in other modules, passed as argu...

Inline-threaded interpretation is a recent technique that improves performance by eliminating dispatch overhead within basic blocks for interpreters written in C [11]. The dynamic class loading, lazy class initialization, and multi-threading features of Java reduce the effectiveness of a straight-forward implementation of this technique within Java interpreters. In this paper, we introduce prep...

The Wikipedia XML collection turned out to be rich of marked-up phrases as we carried out our INEX 2007 experiments. Assuming that a phrase occurs at the inline level of the markup, we were able to identify over 18 million phrase occurrences, most of which were either the anchor text of a hyperlink or a passage of text with added emphasis. As our IR system — EXTIRP — indexed the documents, the ...

The High-Luminosity project (HL-LHC) of the CERN Large Hadron Collider (LHC), requires low $\beta$ * quadrupole magnets in Nb notation="LaTeX">$_\text{3}$ Sn technology that will be installed on each side ATL...

In this paper, the design and implementation of plasma antenna array with beam forming is discussed. The structure consists of a circular array of plasma tube enclosed in a unipolar UHF band monopole antenna. Beam forming is possible by stimulated plasma tubes. The combination of the above antenna with plasma excitation controller makes a beam forming smart antenna. An experimental model in UHF...

A null steering GPS antenna array is designed in this paper. In the proposed method, the exact full wave antenna radiation properties with the effect of mutual couplings and nearby scatterers are considered to calculate the array steering vector, precisely. Although the proposed method is not constrained by the array geometry and the antenna element specifications, a five patch antenna elements...

Although the widely linear least mean square error (WLMMSE) receiver has been an appealing option for multiple-input-multiple-output (MIMO) wireless systems, a statistical understanding on its pose-detection signal-to-interference-plus-noise ratio (SINR) in detail is still missing. To this end, we consider WLMMSE MIMO transmission system with rectilinear or quasi-rectilinear (QR) signals over u...
