Cerebrovascular Disease 2: Stroke (DRAFT)

2018
The video in this chapter explores cerebrovascular disease, and focuses on stroke. It discusses the definition of stroke as a sudden focal neurologic deficit that persists for more than 24 hours, as well as ischemic strokes (embolic, thrombotic, or due to hypoperfusion), and intraparenchymal hemorrhagic strokes.

Newly Developed 2-Stroke EHVE

2015
Although this chapter is also devoted to a 2-stroke type of the EHVE, the major difference between it and the previous version refers to a size of heat exchangers which introduce an essential change in heat delivery.

Predictive Maintenance System for 2 Stroke Diesel Engines

Volume 8: Dynamic Systems and Control, Parts A and B, 2010
Maintenance cost and unexpected failures can be drastically reduced in low speed diesel engines using vibro-acoustic condition monitoring. This methodology has presented as a reliable method for detection of manufacturing faults, running damages and other abnormalities in engine and its components.

Optimization of a Direct-Injected 2-Stroke Cycle Snowmobile

SAE Technical Paper Series, 2003
A student design team at Colorado State University (CSU) has developed an innovative snowmobile to compete in the Clean Snowmobile Challenge 2003 competition. This engine concept was originally developed for the CSC 2002 competition and demonstrated the lowest emissions of any engine that competed that year.

A parametric model of a 2-stroke engine for design and analysis

Computer Methods in Applied Mechanics and Engineering, 1996
Abstract In this paper we demonstrate a procedure for designing a two-stroke engine with good scavenging properties. To achieve this, a method of surface design, referred to as the Partial Differential Equation (PDE) Method, is utilised to represent the critical elements of the internal geometry of the engine.

Performance optimisation of a marine 2-stroke diesel engine

International Journal of Quality Engineering and Technology, 2011
Many companies no longer need to rely on periodic inspections to determine machinery condition but they can also retrieve information from computerised continuous monitoring systems. Through appropriate software and hardware installation, these systems can diagnose possible failures of the machinery and predict needed maintenance.

Investigation of particles emitted from modern 2-stroke scooters

Atmospheric Environment, 2008
Transmission electron microscopy (TEM), combined with X-ray energy dispersive spectroscopy (EDS)—both single and tandem differential mobility analyzer (TDMA)—have been used to investigate particles emitted by two modern 2-stroke scooters with different mixture preparation systems (direct injection and carburetor).

2-Stroke Externally Scavenged Engines for Range Extender Applications

SAE Technical Paper Series, 2012
In this work, the authors assess the potential of the 2-Strokeconcept applied to Range Extender engines, proposing 3different configurations: 1) Supercharged, CompressionIgnition; 2) Turbocharged, Compression Ignition; 3)Supercharged, Gasoline Direct Injection. All the enginesfeature a single power cylinder of 0.49l, external air feed bypiston pump and

A New Combustion System for 2-Stroke HSDI Diesel Engines

SAE Technical Paper Series, 2007
The Department of Mechanical and Civil Engineering (DIMeC) of the University of Modena and Reggio Emilia is developing a new type of small capacity HSDI 2-Stroke Diesel engine, featuring a specifically designed combustion system. The present paper is focused on the analysis of the combustion process, investigated by means of a customized version of the
