Disclaimer: These notes are intended to be an accessible introduction to the subject, with no pretense at completeness. In general, you can find more thorough discussions in Oppenheim's book. Please let me know if you find any typos. In this lecture, we will begin to discuss who the poles and zeros of a rational Z-transform H(z) combine to shape the frequency response H(e jω).

This study explores, through semi-structured interviews, team member perceptions of effectiveness in Partially Distributed Team work. A partially distributed team (PDT) is a virtual team, in which some members are collocated, yet others are geographically dispersed, and communication between them is primarily by electronic media. Researchers have identified an overarching problem in partially d...

The goal of the presented project is to assign a structure of clauses to Czech sentences from the Prague Dependency Treebank (PDT) as a new layer of syntactic annotation, a layer of clause structure. The annotation is based on the concept of segments, linguistically motivated and easily automatically detectable units. The task of the annotators is to identify relations among segments, especiall...

A partially distributed team (PDT) consists of two or more subteams that are separated geographically. In a PDT, members of a given subteam are co-located, but they collaborate with members of geographically distant subteams. PDTs are commonplace across diverse IT settings, including outsourcing, off-shoring, and distributed organizations. Often the distance separating subteams spans multiple t...

In this brief, an algorithm for controlling chaotic systems using small, continuous time perturbations is presented. Stabilisation is achieved by self controlling feedback using low order LTI filters. The algorithm alleviates the need of complex calculations or costly delay elements, and can be implemented in a wide variety of systems using simple circuit elments only.

Twelve years ago, PROCEEDINGS OF THE IEEE devoted a special section to the synchronous languages. This paper discusses the improvements, difficulties, and successes that have occured with the synchronous languages since then. Today, synchronous languages have been established as a technology of choice for modeling, specifying, validating, and implementing real-time embedded applications. The pa...

Data are usually collected in a raw format and thus the inherent information is difficult to understand. Therefore, raw data need to be summarized, processed, and analyzed. However, no matter how well manipulated, the information derived from the raw data should be presented in an effective format, otherwise, it would be a great loss for both authors and readers. In this article, the techniques...

Our paper comments on the divergences of the deep syntactic layers of Czech and English. We point out several phenomena potentially problematic for the syntactic alignment. We argue that at least some of the problems are caused by improper inferences from the deep syntactic layer of one language into the deep structures of the other one, and as such, they can be repaired on the theoretical level.

In this paper we present a 3D animated agent with synthesized face, speech and behavior, which is capable of automatic motion generation with a little user support of text annotation. Users without artistic skills are also capable of easy creation and extension of their own agents with tailor-made appearance and motion. Its implementation and compact size allows for easy use on the Internet as ...

It is rarely possible to successfully contain an outbreak of an infectious animal disease, or to respond effectively to a chemical residue incident, without the use of a system for identifying and tracking animals. The linking of animals at the time they are slaughtered--through the use of identification devices or marks and accompanying movement documentation--with the meat produced from their...
