In order to show that a system for text understanding has produced a sound representation of the semantic and pragmatic contents of a story, it should be able to answer questions about the participants and the events occurring in the story. This requires processing linguistic descriptions which are lexically expressed but also unexpressed ones, a task that, in our opinion, can only be accomplis...

Topic Detection and Tracking (TDT) is an important research topic in data mining and information retrieval and has been explored for many years. Most of the studies have approached the problem from the event tracking point of view. We argue that the definition of stories as events is not reflecting the full picture. In this work we propose a story tracking method built on crowd-tagging in socia...

The main goal of this thesis was to develop an experimental environment for the test time minimization problem. It assumes Hybrid BIST architecture and targets System-on-Chip designs. The thesis is based on methodology developed during the work and demonstrates the feasibility of the proposed methodology together with experimental results. First two sections of this thesis explore the actuality...

In this paper, we study the average packet error probability (APEP) and effective throughput (ET) of control link in unmanned-aerial-vehicle (UAV) communications, where ground central station (GCS) sends signals to UAV that requires ultra-reliable low-latency communications (URLLC). To ensure low latency, short packets are adopted for signal. As a result, Shannon capacity theorem cannot be here...

Seawalls are built for Protecting of beaches against waves and preventing the progression of water to the beach. For a proper understanding about these constructions, a suiTable information about applied loads on these constructions should be existed. One of the important load that applied on these constructions is sea wave. Others loads are included: weight force of the walls, weight force of ...
