Impact of distributed generations with energy storage devices on the electric grid

Srivastava, Anurag K.; Kumar, Aarthi A.; Schulz, Noel N. (2013-01-25)

The commonly used Distributed Generations (DG) technologies include wind generators, photovoltaics, and biomass generators with their sizes varying between several kW to a few MW. Energy storage devices are generally used ...
Impact of preventive responses to epidemics in rural regions

Schumm, Phillip; Schumm, Walter R.; Scoglio, Caterina M. (2013-04-16)

Various epidemics have arisen in rural locations through human-animal interaction, such as the H1N1 outbreak of 2009. Through collaboration with local government officials, we have surveyed a rural county and its communities ...
Introduction of carrier interference to spread spectrum multiple access

Nassar, C.R.; Natarajan, Bala; Shattil, S. (Institute of Electrical and Electronics Engineers, 2010-07-15)

This paper introduces a new scheme for spread spectrum multiple access. Like MC-CDMA, this scheme accomplishes spectral spreading by transmission of identical data over N carriers simultaneously. However, unlike any existing ...
Load shedding strategies for preventing cascading failures in power grid

Pahwa, Sakshi; Scoglio, Caterina M.; Das, Sanjoy; Schulz, Noel N. (2013-09-06)

Load shedding has always been a commonly adopted method in emergency situations to maintain power system reliability. Several load reduction strategies have been suggested in the past but most are complex and not scalable. ...
Maximizing algebraic connectivity in interconnected networks

Shakeri, Heman; Albin, Nathan; Sahneh, Faryad D.; Poggi-Corradini, Pietro; Scoglio, Caterina

Algebraic connectivity, the second eigenvalue of the Laplacian matrix, is a measure of node and link connectivity on networks. When studying interconnected networks it is useful to consider a multiplex model, where the ...
Modeling and Forecasting Secondary User Activity Considering Bulk Arrival and Bulk Departure Traffic Model

Akter, Lutfa; Natarajan, Bala (Institute of Electrical and Electronics Engineers, 2010-07-14)

In this paper, we consider an Erlangian process model for secondary user (SU) traffic in a cognitive radio network (CRN). Unlike prior efforts that focused on Poisson traffic models, the model captures bulk arrival and ...
Modeling fairness in resource allocation for secondary users in a competitive cognitive radio network

Akter, Lutfa; Natarajan, Bala (IEEE, 2010-07-07)

We consider a multi-channel cognitive radio network (CRN) where multiple secondary users share a single channel and multiple channels are simultaneously used by a single secondary user (SU) to satisfy their rate requirements. ...
Network clustering and community detection using modulus of families of loops

Shakeri, Heman; Poggi-Corradini, Pietro; Albin, Nathan; Scoglio, Caterina

We study the structure of loops in networks using the notion of modulus of loop families. We introduce an alternate measure of network clustering by quantifying the richness of families of (simple) loops. Modulus tries to ...
The network level reproduction number for infectious diseases with both vertical and horizontal transmission

Xue, Ling; Scoglio, Caterina M. (2013-08-16)

A wide range of infectious diseases are both vertically and horizontally transmitted. Such diseases are spatially transmitted via multiple species in heterogeneous environments, typically described by complex meta-population ...
A network-based meta-population approach to model Rift Valley fever epidemics

Xue, Ling; Scott, Harvey Morgan; Cohnstaedt, Lee W.; Scoglio, Caterina M. (2012-08-01)

Rift Valley fever virus (RVFV) has been expanding its geographical distribution with important implications for both human and animal health. The emergence of Rift Valley fever (RVF) in the Middle East, and its continuing ...
A novel single-phase inverter with D-STATCOM capability for wind applications

Sotoodeh, Pedram; Miller, Ruth Douglas (2014-01-06)

The modular multilevel converter (MMC) is an attractive topology for HVDC/FACTS systems. In this paper a new single-phase MMC-based D-STATCOM inverter for grid connection is proposed. The proposed inverter is designed for ...
On the existence of a threshold for preventive behavioral responses to suppress epidemic spreading

Sahneh, Faryad Darabi; Chowdhury, Fahmida N.; Scoglio, Caterina M. (2012-11-20)

The spontaneous behavioral responses of individuals to the progress of an epidemic are recognized to have a significant impact on how the infection spreads. One observation is that, even if the infection strength is larger ...
Optimal control of voltage and power in a multi zonal MVDC shipboard power system

Kankanala, Padmavathy; Srivastava, Suresh C.; Srivastava, Anurag K.; Schulz, Noel N. (2012-10-08)

The Multi-Zonal Medium Voltage DC (MVDC) Shipboard Power System (SPS) architecture, proposed by the U.S Navy for their future combatant system, consists of several Voltage Source Converters (VSCs). The proposed architecture ...
Optimal intentional islanding to enhance the robustness of power grid networks

Pahwa, Sakshi; Youssef, M.; Schumm, Phillip R. B.; Scoglio, Caterina M.; Schulz, Noel N. (2013-09-26)

Intentional islanding of a power system can be an emergency response for isolating failures that might propagate and lead to major disturbances. Some of the islanding techniques suggested previously do not consider the ...
Performance Analysis of Asynchronous Carrier InterferometryMC-CDMA Uplink with Interference Cancellation Techniques

Thippavajjula, V.; Natarajan, Bala (Institute of Electrical and Electronics Engineers, 2010-08-10)

In this paper, we analyze the uplink performance of an asynchronous carrier interferometry/MC-CDMA, with nonlinear parallel and serial interference cancellation techniques. Specifically, we employ the new variant of parallel ...
Performance measurement for brain-computer or brain-machine interfaces: a tutorial

Thompson, David E.; Quitadamo, Lucia R.; Mainardi, Luca; Laghari, Khalil ur Rehman; Gao, Shangkai; Kindermans, Pieter-Jan; Simeral, John D.; Fazel-Rezai, Reza; Matteucci, Matteo; Falk, Tiago H.; Bianchi, Luigi; Chestek, Cynthia A.; Huggins, Jane E. (2014-10-16)

Objective. Brain–computer interfaces (BCIs) have the potential to be valuable clinical tools. However, the varied nature of BCIs, combined with the large number of laboratories participating in BCI research, makes uniform ...
