a proposed strategy for research misconduct policy: a review on misconduct management in health research system

background: today, with the rapid growth of scientific production, research misconduct has become a worldwide problem. this article is intended to introduce the successful experience on the management of research paper misconducts in the field of health research. methods: our aim was to design and develop the strategy for research misconduct policy. focusing on the national regulatory system, w...

Proposed Vertical Expansion Tunnel

It is proposed that the adverse effects from secondary diaphragmrupture in an expansion tunnelmaybe reducedor eliminated by orienting the tunnel vertically, matching the test gas pressure and the accelerator gas pressure, and initially separating the test gas from the accelerator gas by density stratification. This proposed configuration is termed the vertical expansion tunnel. Two benefits are...

Measurements and Modeling of Acoustic Scattering from Unexploded Ordnance (UXO) in Shallow Water

Introduction: The gradual development of coastal areas throughout the world in proximity to military training ranges and areas of past conflict has created a need to locate underwater unexploded ordnance (UXO). These ordnance, which may have veered off course and failed to detonate when they were initially released, may still pose a risk of explosion if they are subject to handling. This compli...

Microphone Array Phased Processing System (MAPPS): Phased Array System for Acoustic Measurements in a Wind Tunnel

A processing system has been developed to meet increasing demands for detailed noise measurement of aircraft in wind tunnels. Phased arrays enable spatial and amplitude measurements of acoustic sources, including low signal-to-noise sources not measurable by conventional measurement techniques. The Microphone Array Phased Processing System (MAPPS) provides processing and visualization of acoust...
