This document describes a set of Extension Headers for the Unidirectional Lightweight Encapsulation (ULE), RFC 4326. The Extension Header formats specified in this document define extensions appropriate to both ULE and the Generic Stream Encapsulation (GSE) for the second-generation framing structure defined by the Digital Video Broadcasting (DVB) family of specifications.

A new optical fiber and method of manufacturing the same developed for use with surgical laser systems. The fiber core utilizes an ultra-low expansion (ULE) material. The preferred ULE fiber consists of silicon dioxide core doped with titanium dioxide which is cladded and jacketed for chemical and abrasion resistance. The resulting fiber is stable against degradation due to thermal expansion.

There is growing interest in providing multimedia and broadband access over satellites. However there are several technical challenges need to be addressed. One challenge is security in terms of understanding threats and providing an effective security system. Also this paper presents a ULE security solution using ULE mandatory extension headers. The design issues and choices are discussed. The...

The unified logical effort (ULE) model for delay evaluation and minimization in paths composed of CMOS logic gates and resistive wires is presented. The method provides conditions for timing optimization while overcoming the limitations of standard logical effort (LE) in the presence of interconnects. The condition for optimal gate sizing in a logic path with long wires is also presented. This ...

I n September 2001, Jernej Ule began his Ph.D. work in Robert Darnell's lab at the Rockefeller University in New York City. Although he undertook an old project that no one expected to turn up anything of interest, Ule soon stunned everyone by turning the endeavor into the premier work in the lab, according to Darnell. The project was to develop a new technique, called cross-linking and immunop...

This paper investigates the performance of UDP-based protocols operating over a DVB satellite link. The first part of the paper describes the UltraLightweight Encapsulation (ULE), and compares this with the Multi Protocol Encapsulation (MPE), focusing on UDP traffic. The second examines the potential use of IP protocol header compression to improve the transmission efficiency of links. Performa...

Urban land expansion (ULE) is a crucial factor for socioeconomic and environmentally sustainable development. However, nowadays, the unprecedented scale of high-speed railway (HSR) construction in China could exert an important influence on ULE. This manuscript first reveals mechanism HSR ULE then employs difference-in-difference (DID) models to investigate this effect based data 280 prefecture...

[Abstract] In this paper, the transport efficiency of Multi Protocol Encapsulation (MPE), Unidirectional Lightweight Encapsulation (ULE) and Generic Stream Encapsulation (GSE) for typical IP packet sizes is compared. Moreover, the aggregated efficiency when applying packet-level forward error correction (PL-FEC) with MPE, ULE and GSE is also analyzed. MPE-FEC is the mechanism used by DVB-H wher...
