The Prague Dependency Treebank (PDT, as described, e.g., in (Hajič, 1998) or more recently in (Hajič, Pajas and Vidová Hladká, 2001)) is a project of linguistic annotation of approx. 1.5 million word corpus of naturally occurring written Czech on three levels (“layers”) of complexity and depth: morphological, analytical, and tectogrammatical. The aim of the project is to have a reference corpus...

Steganography is the art and science of concealing information in such a way that only the sender and intended recipient of a message should be aware of its presence. Digital steganography has been used in the past on a variety of media including executable files, audio, text, games and, notably, images. Additionally, there is increasing research interest towards the use of video as a media for...

This paper presents a sophisticated way to search valency lexicons. We provide a visualization of lexicons with such built-in searching that allows users to draw sophisticated queries in a graphical mode. We exploit the PMLTQ, a query language based on the tree editor TrEd. For demonstration purposes, we focus on VALLEX and PDT-VALLEX, two Czech valency lexicons of verbs. We propose a common le...

The surface of Cd1-xZnxTe (CZT) material has high resistivity but is not a perfect dielectric. Even a small surface conductivity can affect the electric field distribution, and therefore, the charge collection efficiency of a CZT pixel detector. The paper describes studies of this phenomenon for several contact configurations made on a single CZT detector. We have determined the maximum inter-c...

Business Intelligence (BI) is one of the fastest growing software sector and software vendors are rapidly developing multiple BI tools to support the growing data analysis needs of organisations. In order to be sustainable in a briskly changing turbulent environment, organisations need to have access to information about their operational performance. BI tools play a vital role in supporting th...

Independent tools and fully integrated systems are currently being applied to educational settings, delivering educational content and activities to students. Asynchronous, computer-mediated communications enable students to reflect upon what they are learning, share their thoughts, and read those of others. Such communication tools facilitate active and collaborative learning. Two integrated s...

peripheral lymph nodes, located deep in the subcutaneous tissue, clean antigens from the extracellular fluid. generally, a normal sized lymph node is less than one cm in diameter. peripheral lymphadenopathy (lap) is frequently due to a local or systemic, benign, self-limited, infectious disease. however, it could be a manifestation of underlying malignancy. seventy-five percent of all laps are ...

We present a set of functions in L2([0,∞)) and show it to be a (tight) generalized frame (as presented by G. Kaiser (1994)). The analysis side of the frame operation is called the continuous unified transform. We show that some of the well-known transforms (such as Laplace, Laguerre, Kautz, and Hambo) result by creating different sampling patterns in the transform domain (or, equivalently, choo...

Vehicle crash test is considered to be the most direct and common approach to assess the vehicle crashworthiness. However, it suffers from the drawbacks of high experiment cost and huge time consumption. Therefore, the establishment of a mathematical model of vehicle crash which can simplify the analysis process is significantly attractive. In this paper, we present the application of LPV-ARMAX...

A computational algorithm for the Full Information H control problem for multi-delayed LTI systems is derived. The algorithm is based on a new general operator approach in spectral domain developed recently for finite-dimensional LTI plants. A simplicity of spectral operations and explicit formulas for computation make it possible to generalize it to infinite-dimensional plants. In this paper, ...
