TL;DR: This paper examines the problem of informant accuracy in the production of social network data, through the use of a self-monitoring network, which allows a comparison between cognitive network data and informants' interactive behavior.
Abstract: This paper examines the problem of informant accuracy in the production of social network data, through the use of a self-monitoring network. This allows a comparison between cognitive network data and informants' interactive behavior. Against expectations, it turns out that informants are extremely inaccurate. In other words, informants' reports of their behavior bear little resemblance to their behavior. If an informant claimed to have communicated with some person "the most frequently" then, in fact, he communicated with that person between first and fourth most frequently only 52% of the time. The implications of our findings for sociometric and network analysis are: (1) Attempts to filter out noise in a sociometric network matrix by using sophisticated software are likely to be unproductive. This is because such manipulations assume a much lower level of noise than actually occurs. (2) Due to the low level of informant accuracy, theories of social structure built upon presently available network data...

TL;DR: The problems encountered in packet transportation are identified and strategies to resolve these are proposed and a single-hop network in which no packet routing is involved is proposed.
Abstract: Packet-switching broadcast radio networks are receiving considerable attention as a feasible solution for applications involving fast network deployment requirements, inaccessible physical environments, and mobile communication devices. Such networks also offer economic alternatives to traditional multiplexing schemes for local distribution. Most of the published papers relating to packet-switching broadcast radio networks address the case in which all communication devices are within an effective transmission range of the destination receiver, thus forming a single-hop network in which no packet routing is involved. In this paper, we address multihop networks. The problems encountered in packet transportation are identified and strategies to resolve these are proposed.

TL;DR: The design of minimum cost networks with a given availability is discussed for different models of the cost-availability function in the links and algorithms are given for its exact or approximate evaluation.
Abstract: In order to design an available network efficiently, a parameter characterizing the network availability is needed. The global availability is suggested and algorithms are given for its exact or approximate evaluation. The design of minimum cost networks with a given availability is discussed for different models of the cost-availability function in the links. Some example network optimizations are reported.

TL;DR: The semantic structure for Shakespeare's "Th' expense of spirit" (Sonnet 129) is given by an abstract pattern for the Fortunate Fall, which is linked to a pattern specifying a fragment of the conceptual basis for faculty psychology.
Abstract: A cognitive network is a type of semantic model developed for simulating natural language on digital computers. A concept is a node in the network while connections between nodes represent relations between concepts. One generates a text by tracing a path through the network and rendering the successive concepts and relations into language according to the appropriate conventions. Elementary concepts are grounded in sensor-motor schemas while abstract concepts are grounded in patterns of network relationship. The semantic structure for Shakespeare's "Th' expense of spirit" (Sonnet 129) is given by an abstract pattern for the Fortunate Fall, which is linked to a pattern specifying a fragment of the conceptual basis for faculty psychology.
