This paper develops a queueing model of a buffer that collects cells for reassembly into packets for a protocol layer above the ATM layer. Whenever the buffer fills with all packets incomplete, a packet must be sacrificed to make room for others. The queueing model estimates the equilibrium fraction of packets sacrificed. Applications to sizing the buffer for a prescribed loss probability are g...

In this paper we propose and implement novel techniques for performance evaluation of web traffic (response time, response code, etc.), with no reassembly of the underlying TCP connection, which severely restricts the traffic analysis throughput. Furthermore, our proposed software for HTTP traffic analysis runs in standard hardware, which is very cost-effective. Besides, we present sub-TCP conn...

In recent minimalist approaches to acquisition, there has been an increasing emphasis on the importance of the lexicon in accounts of syntactic variation. This paper extends the view of lexical feature assembly and reassembly articulated by Lardiere into the open-class lexicon and into the realm of motion events. An original L1 experiment reveals that variation in the syntax of motion events wi...

This paper points out several significant problems in the specification of the Military Standard Internet Protocol (MIL-STD-1777, dated August 1983 [MILS83a]). These results are based on an initial investigation of this protocol standard. The problems are: (1) a failure to reassemble fragmented messages completely; (2) a missing state transition; (3) errors in testing for reassembly completion;...

This article examines the sociological factors that explain why some creative teams are able to produce game changers--cultural products that stand out as distinctive while also being critically recognized as outstanding. The authors build on work pointing to structural folding--the network property of a cohesive group whose membership overlaps with that of another cohesive group. They hypothes...

The Standard Model interprets the weak interaction, e.g. neutron beta decay, to be a short-range field carried by the W and Z bosons. In that interpretation the short range arises because of the heavy mass of the W and Z bosons. This paper reconceptualises the weak interaction and the bosons. The cordus HED notation was used to work out the field structures of the bosons, giving W(r. .a.1 1.1 ....

The contractile cortex is a 50-nm–2-μm-thick layer of cytoskeleton under the plasma membrane that is rich in actin fi laments, myosin II, and actin-binding proteins (Bray and White, 1988). Assembly dynamics and contractility of this layer are thought to generate cortical tension, drive cytokinesis, and play a central role in cell locomotion and tissue morphogenesis (Bray and White, 1988; Albert...
