Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Bayesian Approach to Determining the Orientation of Sound-soft Obstacles with Phaseless Data via Wasserstein Distance
Wasserstein距离 贝叶斯方法 无相数据 软声障碍物
2023/4/27
We present a Bayesian approach to inverse scattering problems of reconstructing the rotation angle in clockwise direction of an acoustically sound-soft obstacle from phaseless far-field data in two di...
Physicists count sound particles with quantum microphone（图）
Physicists count particles quantum microphone
2020/8/14
Physicists have developed a "quantum microphone" so sensitive it can measure individual particles of sound, called phonons.The device, developed through U.S. National Science Foundation-funded re...
Columbia Engineering Researchers Use Acoustic Voxels to Embed Sound with Data
Columbia Engineering Researchers Acoustic Voxels Embed Sound with Data
2016/8/1
Columbia Engineering researchers, working with colleagues at Disney Research and MIT, have developed a new method to control sound waves, using a computational approach to inversely design acoustic fi...
Sound, Complete and Scalable Path-Sensitive Analysis
Static analysis path- and context-sensitive analysis strongest necessary/weakest sufficient conditions
2016/5/24
We present a new, precise technique for fully path- and contextsensitive program analysis. Our technique exploits two observations:First, using quantified, recursive formulas, path- and contextsensiti...
First-ever videos show how heat moves through materials at the nanoscale and speed of sound
First-ever videos heat moves materials nanoscale speed of sound
2016/4/25
Using a state-of-the-art ultrafast electron microscope, University of Minnesota researchers have recorded the first-ever videos showing how heat moves through materials at the nanoscale traveling at t...
THE EFFECT OF SOUND WAVE BENDING ON UNDERWATER ACOUSTIC POSITIONING ACCURACY
Underwater Acoustic Positioning System Sound Speed Sound Wave Bending Positioning Accuracy
2016/3/17
Underwater acoustic positioning system solves the problem of how to position and navigate object underwater. Therefore, it can help people to locate the area of disaster to search and succor. But, bec...
DEVELOPMENT OF HIGH RESOLUTION 3D SOUND PROPAGATION MODEL USING LIDAR DATA AND AIR PHOTO
Laser altimetry 3D modelling Aerial image Clustering Extraction
2016/1/3
Prediction of sound level of real world environment in 3D is important for managing noise pollution, urban planning, virtual realization of sound etc. Commercially available semi-empirical sound model...
MODELING URBAN PATTERNS AND LANDSCAPE CHANGE IN CENTRAL PUGET SOUND
Urban modeling land cover change analysis landscape metrics growth management
2015/8/3
Patterns of urban development across the United States are changing natural landscapes and their dynamics. Although scholars in landscape ecology are increasingly studying the relationship between urb...
CONTRAST BETWEEN LIGHT AND SOUND WAVELENGTHS PERCEIVED BY HUMANS
electromagnetic acoustic waves perceived visible light wavelengths correlated
2015/7/28
A quantitative interrelation between the physical parameters of electromagnetic and acoustic waves perceived by the sight and hearing organs of a human has been discovered. It is shown that visible li...
Highway noise can cause annoyance, affect sleep patterns, and reduce the property value for people in the proximity. Current methods for analyzing the effectiveness of sound barriers only take loudnes...
UBISOUND: DESIGN A USER GENERATED MODEL IN UBIQUITOUS GEOSPATIAL INFORMATION ENVIRONMENT FOR SOUND MAPPING
Ubiquitous GIS VGI Spatial Analysis Sound Mapping Context Awareness Risk Assessment
2014/12/1
In this paper, we study how mobile computing and wireless technologies can be explored to provide effective ubiquitous GIS services. Instead of reinventing the wheels, we make use of smartphones, off-...
Making Sense of Sound: Unsupervised Topic Segmentation over Acoustic Input
Making Sense of Sound Unsupervised Topic Segmentation over Acoustic Input
2014/11/27
We address the task of unsupervised topic segmentation of speech data operating over raw acoustic information. In contrast to existing algorithms for topic segmentation of speech, our approach does no...

seabird habitat use temperature-depth profile foraging ecology
2014/11/26
During the summer of 2008 and 2009, we studied the ecology of the Kittlitz’s Murrelet (Brachyramphus brevirostris), a small diving seabird and candidate for the U.S. Endangered Species List, in Prince...
Now, University of Minnesota engineering researchers have developed a chip on which both sound wave and light wave are generated and confined together so that the sound can very efficiently control th...
