Talk Title: Transmit Antenna Selection in Underlay Spectrum Sharing: Role of Interference Constraint, Channel State Information, and Power Adaptation
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Spectrum sharing mitigates the scarcity of radio spectrum by enabling different classes of users to utilize spectrum together without exclusively and inefficiently allocating the spectrum to just one class of users. In the underlay paradigm of spectrum sharing, a low priority secondary user can transmit concurrently in the same spectrum as a high priority primary user but must ensure that the interference it causes to the primary receiver is constrained. We investigate transmit antenna selection to improve the performance of such interference-constrained underlay spectrum sharing systems. It exploits the spatial diversity afforded by multiple antennas but with much less hardware.
We characterize the optimal antenna selection and power adaptation rules for several stochastic interference constraints. The fact that the choice of the antenna at the secondary transmitter is driven not just by the channel gains from it to the secondary receiver's antennas, but also by the interference it causes to the primary receiver makes the class of problems that we study interesting and novel. The optimal antenna selection and power adaptation rules that we arrive at differ significantly from the ad hoc approaches pursued in the literature and lead to markedly lower symbol error rates. They bring out the significant and varied influence the triumvirate of interference constraint, channel state information, and power adaptation has on antenna selection.

Talk Title: Patient-Specific Modeling for Virtual Treatment Planning in Pediatric Cardiology
Abstract: Cardiovascular disease is the leading cause of death worldwide, with nearly 1 in 4 deaths caused by heart disease alone. In children, congenital heart disease affects 1 in 100 infants, and is the leading cause of infant mortality in the US. Patient-specific modeling based on medical image data increasingly enables personalized medicine and individualized treatment planning in cardiovascular disease patients, providing key links between the mechanical environment and subsequent disease progression. We will discuss recent methodological advances in cardiovascular simulations, including (1) optimization and uncertainty quantification for surgical planning, and (2) a unified finite element formulation for fluid structure interaction towards fluid solid growth. Clinical application of these methods will be demonstrated in two applications: 1) a novel surgical method for stage one single ventricle palliation, and 2) virtual treatment planning in pediatric patients with peripheral pulmonary stenosis. We will also provide an overview of our open source SimVascular project, which makes our tools available to the scientific community (www.simvascular.org). Finally, we will provide an outlook on recent successes and challenges of translating modeling tools to the clinic.

Talk Title: Context-Aware Coding for Computing Memories
Series: Center for Cyber-Physical Systems and Internet of Things
Abstract: Error correction and detection are the core components of all modern memory systems. Current computing memory systems use simple coding schemes to simultaneously meet the resiliency and latency requirements. In this talk, we review our recent results on context-aware coding for computing memories, an approach that explicitly takes into account various intrinsic side information for improved robustness to faults. We discuss both error correction and detection, codes' theoretical properties, and provide examples of how these solutions can be implemented in practice. We explicitly describe the special case of the error localization codes. We also discuss promising future directions, connections with classical information theoretic concepts, and other applications. Joint work with C. Schoeny, M. Gottscho, I. Alam, and P. Gupta.

Speaker: Melisa Orta Martinez, Stanford University
Talk Title: Design and Analysis of Open-Source Haptic Devices for Educational Applications
Series: Computer Science Colloquium
Abstract: Open-source hardware significantly impacts the development of technology by allowing communities of users with varied expertise to share, customize and collectively improve on designs. Most haptic hardware available outside of the research community is proprietary and expensive. This prevents communities of users from easily obtaining, building, modifying, and learning from the devices. I propose that the ability to easily obtain, assemble and customize a haptic device is especially important for educational applications. In this talk I present three open-source haptic devices, for which I carefully considered trade-offs in cost, ease of making, and performance -- toward making haptic devices more accessible for educational applications.
This lecture satisfies requirements for CSCI 591: Research Colloquium.

Talk Title: Advanced theories of two-phase flow in deformable porous media; experimental and computation studies
Abstract:
Two-phase flow in porous media is traditionally modeled using a modified form of Darcy's law, two volume balance equations, and a so-called capillary pressure-saturation relationship. Darcy's Law was proposed more than 150 years ago for the flow of a single fluid in soil. Since then, this equation, in almost original form, has been assumed to be applicable to more and more complicated porous media. But, there are many shortcomings of the so-called extended Darcy's Law. Also, the empirical relationship between capillary pressure and saturation is known to suffer from some important shortcoming (it is hysteretic and may depend on the rate of flow or rate of change of saturation).
In this lecture, we present a new theory of two-phase flow, which comprises a truly extended Darcy's law and a new capillarity theory, which has five main features: i) pressure gradient is not the only driving force for flow, ii) saturation and pressure are not the only state variables; fluid-fluid specific interfacial area is another macroscale state variable, iii) capillary pressure is an intrinsic property of the porous medium and is not only a function of saturation but also fluid-fluid specific interfacial areas, iv) effective stress parameter is a function of fluid-fluid specific interfacial area as well as saturation, and v) there is a dynamic (or non-equilibrium) capillarity effect. We provide experimental evidences for the validity of the new theory. Also, results of pore-scale and continuum-scale simulations are provided to illustrate the significance of new theory at various scales.

Information Sciences Institute
Conferences, Lectures, & Seminars
Speaker: Soravit Beer Changpinyo , Google AI
Talk Title: Tightly Connecting Vision and Language
Series: Natural Language Seminar
Abstract: Remarkable progress has been made at the intersection of vision and language. While showing great promise, current vision and language models do not function well in the wild. In this talk, I will present our recent efforts aiming to bridge this gap for the tasks of image captioning and visual question answering. I will first describe several practical limitations of current benchmarks as a yardstick for grounded language understanding and visual reasoning. Then, I will describe our simple approach to transfer learning, where we leverage large-scale ultrafine grained data as a means to address the long tail of language. Finally, given these results, I will outline future directions and survey a variety of on-going work along the line of making vision and language research useful.
Biography: Soravit Changpinyo is a Software Engineer at Google AI. His research interests are in machine learning with applications to computer vision and natural language processing. Prior to joining Google, he was a PhD candidate and an Annenberg Fellow at the University of Southern California, advised by Fei Sha.

Talk Title: Ecogenomics of freshwater microbial communities
Abstract: Freshwater bacterial communities underpin all biogeochemical cycles in lakes and are outstanding model systems with which to study ecological and evolutionary processes in microbes. We are partnered with the North Temperate Lakes Long Term Ecological Research site and have access to a rich time series of microbial community data extending nearly two decades. In this talk I will compare patterns of microbial community assembly and dynamics in two sharply contrasting lakes using 16S rRNA gene tag sequencing, explore population structure using single cell genomics and metagenomics, and propose a new genomics-based framework for thinking about traits within complex microbial communities.
Biography: My students and I study the microbial ecology of both natural and engineered systems. We use molecular tools to investigate microbial community structure and function in lakes and activated sludge. More recently, we have been using high-frequency environmental sensor networks to measure important variables that we know influence bacterial communities. Sensor data provided through the Global Lake Ecological Observatory Network (http://www.gleon.org) guides our adaptive sampling efforts and provides rich contextual data for our studies of lake bacterial community ecology. We are particularly interested in phosphorus as a nutrient driving eutrophication, and the role that bacteria play in phosphorus cycling. We are also engaged in metagenomic and post-genomic approaches to dissecting the metabolism of bacteria specialized in the sequestration of phosphorus in activated sludge. This information will ultimately lead to the construction of more predictive mechanistic and ecosystem-scale models to describe such processes as wastewater treatment and freshwater nutrient cycling
