Bayesian Density Estimation via Multiple Sequential Inversions of 2-D Images with Application in Electron Microscopy
We present a new Bayesian methodology to learn the unknown material density of a given sample by inverting its two-dimensional images that are taken with a Scanning Electron Microscope. An image results from a sequence of ... -
Bayesian learning of material density function by multiple sequential inversions of 2-D images in electron microscopy
Chakrabarty, Dalia; Paul, Shashi (Conference)We discuss a novel inverse problem in which the data is generated by the sequential contractive projections of the convolution of two unknown functions, both of which we aim to learn. The method is illustrated using an ... -

Capacitance-voltage analysis of ZrO2 thin films deposited by thermal MOCVD technique.
The capacitance-voltage (C-V) characteristics of thin films of ZrO2 deposited by thermal metal-organic chemical vapour deposition (MOCVD) have been analyzed. The films were grown at three different temperatures (500, 550 ... -
Comparison of the antibacterial effect of silver and zinc oxide in solution and on coated surfaces
Tejpal, Jyoti; Cross, R. B. M.; Paul, Shashi; Jenkins, R. O.; Laird, Katie (Conference)The occurrence of antibiotic resistance of pathogens is a continuing problem for the health care industry. At least 70% of Hospital Acquired Infections (HAIs) are known to be resistant to a minimum of one or two of the ... -
Creating Electrical Bistability Using Nano-bits – Application in 2-Terminal Memory Devices
Salaoru, Iulia; Alotaibi, Sattam; Al Halafi, Zahara; Paul, Shashi (Article)Intensive research is currently underway to exploit the highly interesting properties of nano-bits (“nano-sized particles and molecules”) for optical, electronic and other applications. The basis of these unique properties ... -
