Diesel in a Fix

prediction of ignition delay period in d.i diesel engines

a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

FIX - W FIX - E National Backbone Networks

This paper presents the results of a measurement study of the T1 NSFNET backbone. We rst discuss the measurement environment and approach to data collection. We then present measurements results for: long-term growth in traac volume, including attribu-tion to domains and protocols; trend in average packet size on the network, both over long and medium term intervals; most popular sources, desti...

A "fix" of reality.

Material witness: A quick fix.

M AERIA L W TN SS Delicately patterned microand nanostructures can be produced without the need for laborious fabrication, by relying on physical forces to organize materials spontaneously into intricate forms. The capacity of soft materials such as surfactants and block copolymers to self-organize into regular patterns has been long recognized1–3, and superlattices and other ordered arrays in ...

To Fix or Not to Fix? That is the Question.

Eventually, the algorithm for when to intervene on the tricuspid valve during left sided valve surgery will be more robust. Better discriminatory preoperative data will be required to sort the role of annular size, right ventricular function, and pulmonary artery pressures. As for now, there is a paucity of evidence that an aggressive approach to fixing moderate functional TR during left sided ...
