Advancements in widefield infrared spectromicroscopy have recently been demonstrated following the commissioning of IRENI (InfraRed ENvironmental Imaging), a Fourier Transform infrared (FTIR) chemical imaging beamline at the Synchrotron Radiation Center. The present study demonstrates the effects of magnification, spatial oversampling, spectral(More)
The Short Message Service (SMS) is one of the most successful services in existing cellular networks. The SMS provides a means of sending messages of limited size to and from Global System for Mobile Communications (GSM) or Universal Mobile Telecommunications System (UMTS) phones. SMS technology has evolved out of the GSM standard and presently, the 3rd(More)
Smoldyn is a spatio-temporal biochemical reaction network simulator. It belongs to a class of methods called particlebased methods and is capable of handling effects such as molecular crowding. Individual molecules are modelled as point objects that can diffuse and react in a control volume. Since each molecule has to be simulated individually, the(More)
In the following paper we present techniques for data-parallel execution of the Cellular Potts Model (CPM) on Graphics Processing Units (GPUs). We have developed data-structures and algorithms that are optimized to use available hardware resources on the GPU. To the best of our knowledge, this is the first attempt at using data-parallel techniques for(More)
Optical Coherence Tomography (OCT) is an emerging technique in the field of biomedical imaging, with applications in ophthalmology, dermatology, coronary imaging etc. OCT images usually suffer from a granular pattern, called speckle noise, which restricts the process of interpretation. Therefore the need for speckle noise reduction techniques is of high(More)
