We propose and demonstrate the time stretch optical header recognition technique where a high speed header is extracted and slowed down by more than an order of magnitude, in optical domain, to facilitate the capture and processing in electronic domain. The technique can be implemented in continuous time or discrete time. Both implementations are experimentally demonstrated for stretching a 10 ...

This paper is concerned with the creep-damage modelling of a Grade 91 pressurised header, which was observed to undergo in-service cracking in weldments. A multi-axial creep damage model Kachanov type, single state variable, has been implemented into finite element analysis study responses weldments and sub-zones i.e. base metal (BM), weld (WM) heat-affected zone (HAZ). Material properties for ...

It is common but perhaps misguided to provide extensibility for a layer X header in the layer X header. Strawman principle: In a middlebox world, it is both more principled and more pragmatic to extend the layer X header within layer X + 1 (i.e. within the payload encapsulated by the layer X header). For instance, extensions to the IP header should not be located in a chain of extensions to the...

Wireless multi–hop networks are becoming more popular and the demand for multimedia services in these networks rises with the number of their implementations. Header compression schemes that compress the IP/UDP/RTP headers to save bandwidth for multimedia streams were typically evaluated only for individual links, not taking into account the savings that can be achieved using header compression...

Voice over IP (VoIP) typically uses the encapsulation voice/RTP/UDP/IP. When MPLS labels are added, this becomes voice/RTP/UDP/IP/MPLS-labels. For an MPLS VPN, the packet header is typically 48 bytes, while the voice payload is often no more than 30 bytes, for example. Header compression can significantly reduce the overhead through various compression mechanisms, such as enhanced compressed RT...

Header and footer are important in digital investigation for JPEG file detection as only 16% of files are fragmented. The use of efficient algorithm to detect them is vital to reduce time taken for analyzing ever increasing data in hard drive or physical memory. Even though there are few applications developed for file carving that rely on header and footer e.g. Foremost, Scalpel; however the a...

In this paper we present a modification of a typical turbo code to allow for the header bits to be decoded much faster than the other bits. This gives the decoder a possibility to discard data packets not addressed to it, and saves time and power since fewer iterations need to be performed to reliably decode the header. The proposed algorithm frequently terminates the first trellis of the turbo...

This document defines the HTTP Cookie and Set-Cookie header fields. These header fields can be used by HTTP servers to store state (called cookies) at HTTP user agents, letting the servers maintain a stateful session over the mostly stateless HTTP protocol. Although cookies have many historical infelicities that degrade their security and privacy, the Cookie and Set-Cookie header fields are wid...

wheat is one of the most important food staff in consumption pattern of each country. more than 50 percent of energy is provided by bread in the developing countries. the aim of this study was measuring wheat losses during pre-harvest and harvest stages in chaharmahal and bakhtiari province of iran in year 2013. wheat losses at harvest stages were measured to wheat varieties in 2 levels of omid...
