Time delay spread and path loss measurements were performed in a large, active train yard to support development of intra-yard wireless communication systems, such as those intended to communicate with individual railcars and for track-to-terminal communications. Propagation measurements focused on three sites within the train yard: a close-in site, a paralleltrack site, and a cross-track site....

This document specifies tests to determine if multiple independent instantiations of a performance-metric RFC have implemented the specifications in the same way. This is the performance-metric equivalent of interoperability, required to advance RFCs along the Standards Track. Results from different implementations of metric RFCs will be collected under the same underlying network conditions an...

if we accept this idea that in talking about art, there is a chasm between thought and unthought debating on art theory in the sociohistorical context of after revolutionary iran requires at least two items in which understanding and creating art meet one another: 1) art as door separates intelligible from sensible, rational from irrational, and logos from pathos as well and 2) art as bridge no...

The traditional retrieval models based on term matching are not effective in collections of degraded documents (output of OCR or ASR systems for instance). This paper presents a n-gram based distributed model for retrieval on degraded text large collections. Evaluation was carried out with both the TREC Confusion Track and Legal Track collections showing that the presented approach outperforms ...

the main purpose of this paper is identifying the current situation of iranian digital libraries in terms of interoperability abilities and proposing an interoperability solution for iranian digital libraries. analytical survey is used in this research. in fact, questionnaire and observation were used for collecting data about the current situation of iranian digital library applications. the g...

We show that state-of-the-art services for creating trusted timestamps in blockchain-based networks do not adequately allow for timestamping of web pages. They accept data by value (e.g., images and text), but not by reference (e.g., URIs of web pages). Also, we discuss difficulties in repeatedly generating the same cryptographic hash value of an archived web page. We then introduce several req...
