2005-present. Energy intake and energy balance monitoring in free living population. The goal of this proect is to design a werable non-intrusive device for monitoring of energy intake and energy balance.

2004-present. Wearable biofeedback device (aka "sensor shoe") for monitoring of postural control and balance in elderly.

2004-present. Self-powered wireless sensors and energy harvesting.

2003-present.  Wireless Intelligent Sensor and Actuator Network (WISAN). A sensor network targeted toward applications of structural health monitoring. The project includes developement of the network hardware, software, sensors, structural health monitoring methods and energy harvesting techniques. Sponsored by New York State Energy Research and Development Authority (NYSERDA). (more project info...)

2002-present. Sleep state scoring through non-invasive measurements. This project uses the data from Collaborative Home Infant Monitoring Evaluation (CHIME) dataset. Sleep-wake patterns and sleep states are valuable predictors for detection of life-threatening events in infants. 

1996-2002. Automatic damage detection for Armored Vehicle Launched Bridge. The targeted goal was creation of automatic system for detection of strutural damage in AVLB. The damage detection was based on identification of changes in strain energy mode shapes. A set of new methods was developed to allow damage detection without a baseline and to alleviate uncertanty in the data caused by noise and environmental varibility.

2002-2003. Evolving hybrid controllers for unstable systems. Learning methods allow to improve control of complex non-linear system. We are looking at ways to apply learning techniques to unstable systems.

1999. Fuzzy Engine for Java.  A small and efficient Java code to interpret fuzzy rules expressed as text strings.The following application is written in Java and runs in your browser window. A fuzzy logic example: Load sway prevention by a fuzzy controller.

Computational Intelligence

The following definition is quoted from http://www.computelligence.org/download/citutorial.pdf

"A methodology involving computing that exhibits an ability to learn and/or to deal with new situations, such that the system is perceived to possess one or more attributes of reason, such as generalization, discovery, association and abstraction. Silicon-based computational intelligence systems usually comprise hybrids of paradigms such as artificial neural networks, fuzzy systems, and evolutionary algorithms, augmented with knowledge elements, and are often designed to mimic one or more aspects of carbon-based biological intelligence.Computational intelligence comprises practical adaptation concepts, paradigms, algorithms and implementations that enable or facilitate appropriate actions (intelligent behavior) in complex and changing environments."

Biomedical Engineering

The following definition is quoted from http://www.whitaker.org/glance/definition.html

Biomedical engineering is a discipline that advances knowledge in engineering, biology and medicine, and improves human health through cross-disciplinary activities that integrate the engineering sciences with the biomedical sciences and clinical practice. It includes:

1. The acquisition of new knowledge and understanding of living systems through the innovative and substantive application of experimental and analytical techniques based on the engineering sciences.
2. The development of new devices, algorithms, processes and systems that advance biology and medicine and improve medical practice and health care delivery.
