The cloud computing ecosystem comprises hundreds of providers, offering diverse computing services, incompatible APIs, and significantly different pricing models. Cloud application management platforms hide the heterogeneity of the services and APIs, allowing, to varying degrees, portability between providers. These tools remove technical barriers to switching providers, but they do not provide a mechanism for evaluating the cost effectiveness of switching. This talk presents a decision support system, working within cloud application management platforms, that evaluates the costs of a customer’s applications using resources from different cloud service providers. The system (1) generalizes and normalizes multiple cloud pricing models and (2) gathers pricing data from cloud providers. These, in conjunction with the application resource consumption model, allow the cloud pricing module to estimate a price for the application for each cloud provider. To demonstrate this, the cloud pricing module has been integrated with the SlipStream multi-cloud application management platform, allowing its users to optimize their choice of provider(s).

Using the Notre Dame TFET Model for Circuit Design
 Date: Monday, April 10, 2017,11:30 PM – 12:30PM         
Room: SL 165 (723 West Michigan street)
Trond Ytterdal, Ph.D.
Department of Electronic Systems, Norwegian University of Science and Technology
Currently visiting the Department of Electrical Engineering, University of Notre Dame

The tunnel field-effect transistor (TFET) is one of the candidates for beyond CMOS devices. The TFET devices are aimed at supply voltages less than 0.5 V which is enabled by the sub 60 mV sub-threshold swing. To design TFET circuits an analytical device model is required that accurately estimates terminal currents and charges versus terminal voltages. The Notre Dame TFET (NDTFET) model has been developed and coded in Verilog-A. The Verilog-A code has been made publicly available for the global design community at The talk starts with a discussion of the electrical characteristics of TFETs followed by a short description of the most important features of the NDTFET model. Afterwards, several examples are presented that use the NDTEFT model to design analog and mixed-signal integrated circuits, such as, for example, amplifiers, analog-to-digital converters, ultra-low voltage digital circuits, ultra-low voltage oscillators and charge pumps.

Bi-clustering based omics data modeling – from commonality to heterogeneity
DATE:  Feb 17, 2017 , noon
ROOM: SL 165 (723 West Michigan street)
Dr. Chi Zhang,
Department of Medical and Molecular Genetics,
Center for Computational Biology and Bioinformatics

One of the current focuses in precision medicine study is to fully characterize the phenotype associated heterogeneous characteristics shared by certain but unknown subsets of samples. We recently developed a probabilistic model based bi-clustering approach to comprehensively capture the heterogeneous characteristics shared by subset of samples in large scale omics data. With this computational capability, we developed computational frameworks for single cell data analysis and study of drug resistance mechanisms. Based on this capability, we also developed a method to predict the gain or loss of functions led by specific individual or collective effect of mutations by integrating cancer genomics and transcriptomics data.

Dr. Chi Zhang received his B.S degree in Mathematics from Peking University in 2010 and Ph.D. in Bioinformatics from the University of Georgia in 2015.

Control-based Structural Design for Crashworthiness using Cellular Automata
DATE: November 11, 2016, noon

Andres Tovar
Department of Mechanical Engineering,
Indiana University-Purdue University Indianapolis

For more than a decade, there have been various attempts to improve motor vehicle safety by designing crashworthy structures using topology optimization methods. For mildly nonlinear problems, investigators have relied on simplifications of the dynamic multi-body interaction and the structure’s nonlinear behavior to approximate sensitivity coefficients. That approach has been shown to be of limited use in large-scale, industrial applications. This research proposes a new design algorithm inspired in the distributed control mechanisms that govern biological functional adaptation—or the means by which biological structures become better suited to their environment. In this numerical approach, sensor and actuator are distributed throughout a prescribed design domain using cellular automata (CAs). A desired global structural response is achieved by design rules that locally modify the material distribution around each CA. The results obtained by the CA control-based design algorithm show a dramatic improvement with respect to traditional topology optimization. Further improvement is also achieved through the introduction of a design and analysis of computer experiments (DACE) method. Results are demonstrated in the design of various lightweight, energy-absorbing vehicle including progressively folding thin-walled structures.

We are in the era of Big Data, where the sheer volume, high velocity, data heterogeneity and complexity have introduced unprecedented challenges to data mining and machine learning research and their applications in real life. Effectively mining, learning and eventually creating values from Big Data become critical for many high-impact application domains.

In this talk, I will address some Big-Data issues for two specific application domains, i.e., Recommender Systems and Chemical Informatics. For Recommender Systems, I will introduce SLIM, a sparse linear method, that can achieve high prediction accuracy and has low computational requirements for Top-N recommendation from Big Data. I will also present a unified frame based on SLIM that enables effective exploration and incorporation of additional meta-data for better recommendation performance. For Chemical Informatics, I will present my work iSAR on predicting compound activities, where iSAR provides a guided-search approach over the entire chemical space (~10100  compounds) by leveraging available information from related protein targets. I will also briefly talk about my work on Bioinformatics and on-going projects on drug discovery problems.

Title: Optimum Functional Forms of Spoofing Attacks, Optimum Processing for Man-in- the-Middle Attacks and Interesting Implications to Unattacked Quantized Sensor Estimation Systems

Speaker: Rick S. Blum, Robert W. Wieseman Endowed Professor of Electrical Engineering, Electrical and Computer Engineering Dept., Lehigh University

Abstract: Estimation of an unknown deterministic vector from quantized sensor data is considered in the presence of spoofing and man-in-the-middle attacks which alter the data presented to several sensors. First, asymptotically optimum processing, which identifies and categorizes the attacked sensors into different groups according to distinct types of attacks, is outlined in the face of man-in-the-middle attacks. Necessary and sufficient conditions are provided under which utilizing the attacked sensor data will lead to better estimation performance when compared to approaches where the attacked sensors are ignored.  Next, necessary and sufficient conditions are provided under which spoofing attacks provide a guaranteed attack performance in terms of the Cramer-Rao Bound (CRB) regardless of the processing the estimation system employs, thus defining a highly desirable attack.  Interestingly, these conditions imply that, for any such attack when the attacked sensors can be perfectly identified by the estimation system, either the Fisher Information Matrix (FIM) for jointly estimating the desired and attack parameters is singular or the attacked system is unable to improve the CRB for the desired vector parameter through this joint estimation even though the joint FIM is nonsingular.  It is shown that it is always possible to construct such a highly desirable attack by properly employing an attack vector parameter having a sufficiently large dimension relative to the number of quantization levels employed, which was not observed previously. For unattacked quantized estimation systems, a general limitation on the dimension of a vector parameter which can be accurately estimated is uncovered.
