Projection onto Epigraph Sets for Rapid Self-Tuning Compressed Sensing MRI
(IEEE, 2018-12-07)The compressed sensing (CS) framework leverages the sparsity of MR images to reconstruct from undersampled acquisitions. CS reconstructions involve one or more regularization parameters that weigh sparsity in transform ... -
Optimization of a Collapsed Mode CMUT Receiver for Maximum Off-Resonance Sensitivity
(Institute of Electrical and Electronics Engineers, 2018-07-28)We propose an airborne collapse capacitive micromachined ultrasonic transducer (CMUT) as a practical viable ultrasound transducer capable of providing a stable performance at the off-resonance frequencies. Traditional ... -
Emerging accelerator platforms for data centers
(Institute of Electrical and Electronics Engineers, 2017-12-04)CPU and GPU platforms may not be the best options for many emerging compute patterns, which led to a new breed of emerging accelerator platforms. This article gives a comprehensive overview with a focus on commercial platforms. -
A Template-Based Design Methodology for Graph-Parallel Hardware Accelerators
(Institute of Electrical and Electronics Engineers Inc., 2017-05-19)Graph applications have been gaining importance in the last decade due to emerging big data analytics problems such as Web graphs, social networks, and biological networks. For these applications, traditional CPU and GPU ... -
Cognitive and cooperative wireless networks
(Springer-Verlag Italia s.r.l., 2012)The traditional approach of dealing with spectrum management in wireless communications has been the definition of a licensed user granted with exclusive exploitation rights for a specific frequency. While it is relatively ... -
Heterogeneous and opportunistic wireless networks
(Springer-Verlag Italia s.r.l., 2012)Recent years have witnessed the evolution of a large plethora of wireless technologies with different characteristics, as a response of the operators' and users' needs in terms of an efficient and ubiquitous delivery of ... -
The two (computational) faces of AI
(Springer International Publishing, 2013)There is no doubt that AI research has made significant progress, both in helping us understand how the human mind works and in constructing ever more sophisticated machines. But, for all this, its conceptual foundations ... -
Biomedical and biochemical tools of förster resonance energy transfer enabled by colloidal quantum dot nanocrystals for life sciences
(Springer Berlin Heidelberg, 2013)Semiconductor quantum nanocrystals (NCs) provide the ability to control and fine-tune peak emission wavelength using the size effect, with a broad optical absorption band (excitation window) increasing toward UV wavelength ... -
Pricing multiple exercise American options by linear programming
(Springer New York LLC, 2017)We consider the problem of computing the lower hedging price of American options of the call and put type written on a non-dividend paying stock in a non-recombinant tree model with multiple exercise rights. We prove using ... -
Threats and solutions for genomic data privacy
(Springer International Publishing, 2015)With the help of rapidly developing technology, DNA sequencing is becoming less expensive. As a consequence, the research in genomics has gained speed in paving the way to personalized (genomic) medicine, and geneticists ... -
Sampling and discrete linear canonical transforms
(Springer Verlag, 2016)A discrete linear canonical transform would facilitate numerical calculations in many applications in signal processing, scalar wave optics, and nuclear physics. The question is how to define a discrete transform so that ... -
Linear canonical domains and degrees of freedom of signals and systems
(Springer Verlag, 2016)We discuss the relationships between linear canonical transform (LCT) domains, fractional Fourier transform (FRT) domains, and the space-frequency plane. In particular, we show that LCT domains correspond to scaled fractional ... -
Optical implementation of linear canonical transforms
(Springer Verlag, 2016)We consider optical implementation of arbitrary one-dimensional and two-dimensional linear canonical and fractional Fourier transforms using lenses and sections of free space. We discuss canonical decompositions, which are ... -
Fast algorithms for digital computation of linear canonical transforms
(Springer Verlag, 2016)Fast and accurate algorithms for digital computation of linear canonical transforms (LCTs) are discussed. Direct numerical integration takes O(N2) time, where N is the number of samples. Designing fast and accurate algorithms ... -

Peer-to-peer overlay in mobile ad-hoc networks
(Springer US, 2010)Wireless multi-hop networks such as mobile ad-hoc (MANET) or wireless mesh networks (WMN) have attracted big research efforts during the last years as they have huge potential in several areas such as military communications, ... -
Energy efficient routing
(Springer Berlin Heidelberg, 2007)The design of routing protocols for wireless sensor networks (WSNs) requires new approaches to be followed due to the different characteristics and applications. The primary objective to optimise WSNs is energy efficiency, ... -
Localization and tracking of implantable biomedical sensors
(MDPI AG, 2017)Implantable sensor systems are effective tools for biomedical diagnosis, visualization and treatment of various health conditions, attracting the interest of researchers, as well as healthcare practitioners. These systems ...
