Model management is a new approach to meta data management that offers a higher level programming interface than current techniques. The main abstractions are models (e.g., schemas, interface definitions) and mappings between models. It treats these abstractions as bulk objects and offers such operators as Match, Merge, Diff, Compose, Apply, and ModelGen. This paper extends earlier treatments o...

Modern TRIP assisted steels contain retained austenite with carbon concentrations in excess of 1 wt-%. Some of their mechanical properties, in particular the toughness and ductility, rely on the diffusionless transformation of this austenite into high-carbon martensite, induced by stress and strain. The properties can be excellent in spite of the fact that freshly formed high-carbon martensite ...

Wire bonding using copper or insulated wire leads to many advantages and new challenges. Research is intensively performed worldwide, leading to many new findings and solutions. This article reviews recent advances in wire bonding using copper wire or insulated wire for advanced microelectronics packaging. Journal articles, conference articles and patents published or issued recently are review...

Brassinosteroids (BRs) regulate multiple aspects of plant growth and development and require an active BRASSINOSTEROID-INSENSITIVE 1 (BRI1) receptor serine/threonine kinase for hormone perception and signal transduction. In mammals, the transforming growth factor-beta (TGF-beta) family of polypeptides modulate numerous aspects of development and are perceived at the cell surface by a complex of...

in this paper, based on equations of lateral vibrations of wires, a non contact method for measuring instantaneous tension in a wire is introduced. the lateral vibration of the string is measured using an eddy current transducer and is sent to a computer. this signal is then imported to suitable software for fast fourier transform (fft) processing. the first natural frequency of the string is c...

Use of probation and parole has declined since its peak in 2007 but still intrudes into the lives 3.9 million Americans at a scale deemed mass supervision. Originally intended as an alternative to incarceration means rehabilitation for those who have committed crimes, supervision often functions trip wire further criminal legal system contact. This review questions utility supervision, research...

P2P video streaming is receiving enormous attention, and when video is involved, the efficient use of the network becomes a very important issue, specially if live applications are addressed. In this work we study properties of Push/Pull protocols for the exchange of video chunks in non-structured systems. Push/Pull protocols are a broad class of chunk exchange mechanisms where peers alternate ...

TCP traffic round-trip delay measurements have been carried out in the Ericsson Corporate Network. Based on these data a comprehensive analysis has been performed to identify basic state changes in the network and to find the parametric distribution of the round-trip delay. The main finding of our research is that the roundtrip delay can be well approximated by a truncated normal distribution. ...

Many user applications (and the transport protocols that make them possible) require two-way communications. To assess this capability, and to achieve test system simplicity, round-trip loss measurements are frequently conducted in practice. The Two-Way Active Measurement Protocol specified in RFC 5357 establishes a round-trip loss measurement capability for the Internet. However, there is curr...

Purpose – This paper attempts to review recent advances in wire bonding using copper wire. Design/methodology/approach – Dozens of journal and conference articles published recently are reviewed. Findings – The problems/challenges such as wire open and short tail defects, poor bondability for stitch/wedge bonds, oxidation of Cu wire, strainhardening effects, and stiff wire on weak support struc...
