Ground-level ozone concentration is a key indicator of air quality. There may exist sudden changes in ozone concentration data over a long time horizon, which may be caused by the implementation of government regulations and policies, such as establishing exhaust emission limits for on-road vehicles. To monitor and assess the efficacy of these policies, we propose a methodology for detecting ch...

This paper presents a two-dimensional multi-robot cooperative localization and mapping dataset collection for research and educational purposes. The dataset consists of nine sub-datasets, which can be used for studying problems such as robot-only cooperative localization, cooperative localization with a known map, and cooperative simultaneous localization and mapping (SLAM). The data collection...

We consider the problem of simultaneous nite gain L p-stabilization and internal stabilization of linear systems subject to input saturation via linear static state feedback. We show that bounded input nite-gain L p-stabilization and local asymptotic stabilization can always be achieved simultaneously no matter where the poles of the open loop system are, and the locations of these poles play a...

Problems in simultaneous graph drawing involve the layout of several graphs on a shared vertex set. This paper describes a Graph Simultaneous Embedding Tool, GraphSET, designed to allow the investigation of a wide range of embedding problems. GraphSET can be used in the study of several variants of simultaneous embedding including simultaneous geometric embedding, simultaneous embedding with fi...

Some e-shops present product attributes in structured form, but many others use the textual description only. Attributes of products are essential in automated product deduplication. We suggest methods for automated extraction of attributes and their values from product descriptions to a structural form. The structural data extracted from other e-shops are used as background knowledge.

We study the simultaneous embeddability of a pair of partitions of the same underlying set into disjoint blocks. Each element of the set is mapped to a point in the plane and each block of either of the two partitions is mapped to a region that contains exactly those points that belong to the elements in the block and that is bounded by a simple closed curve. We establish three main classes of ...

This note is a resume of Jerry Hausman’s Nake course at the NAKE workshop in Den Haag, The Netherlands in June 2002. It presents an intuitive framework in which the impact of weak/invalid instruments on properties of di¤erent estimators can be analyzed while also suggesting a test to detect the presence of weak/invalid instruments.

a close study of the conduct of a translator or an interpreter indicates that there are a large number of factors which can play a significant role in their success or failure in their profession. the present paper is intended to probe into a number of these factors which appear to have a rather more important role in the profession of interpreters. it is accepted though, by the majority of the...
