Academic Search Engines: Constraints, Bugs, and Recommendation [PDF]
arXiv, 2022 Background: Academic search engines (i.e., digital libraries and indexers) play an increasingly important role in systematic reviews however these engines do not seem to effectively support such reviews, e.g., researchers confront usability issues with the engines when conducting their searches.

Design and development of piston-controlled intake port for 4-stroke engine [PDF]
, 2008 In a two stroke engine, piston control the intake port opening and closing that combine the intake and compression stroke in 1800 crank rotation. The operational concept of two stroke engine is applied to the existing four stroke engine cylinder head ...

From Damage to Functionality: Remanufacturing of Thrust Roller Bearings by Tailored Forming
Advanced Engineering Materials, EarlyView.Herein, the wear and fatigue behavior of repaired bearing raceways with a new powder alloy is investigated using a FE8 test‐rig and an oscillating tribometer. The tests are compared with industrial manufactured bearings to evaluate the repair quality. The repair can extend the service life of the repaired bearing to that of a new bearing and improves ...

Single-cylinder 125 CC stepped piston engine for mobility and portable power generation applications [PDF]
, 2015 Two-stroke engines is far simpler than four-stroke version from its physical perspective. For a given brake output, two-stroke is lighter, easier to work on, and provide higher power-to-weight ratio than the four-stroke, making it suitable for small ...

A Different Perspective on the Solid Lubrication Performance of Black Phosphorous: Friend or Foe?
Advanced Engineering Materials, EarlyView.Researchers investigate black phosphorous (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

The Essence of the Essence from the Web:The Metasearch Engine [PDF]
International Conference on IT, HIT, March 19-21, 2007 (Vol-II)The exponential growth of information source on the web and in turn continuing technological progress of searching the information by using tools like Search Engines gives rise to many problems for the user to know which tool is best for their query and which tool is not.

Mathematically analysis on two stroke uniflow scavenging system [PDF]
, 2007 Conventional 2-stroke engines are commonly used for two-wheeled and marine vehicles that have small engine displacement. However problems such as unstable combustion, high fuel consumption rate, high hydrocarbon (HC) emission need to be resolved.
