There is a long history of attempts to explain why music is perceived as expressive of emotion. Many of the acoustic parameters that are used to communicate emotion in music are also used in human vocal expressions of emotion, suggesting that the...
A mobile agent is an autonomous program that can migrate under its own control from machine to machine in a heterogeneous network. In other words, the program can suspend its execution at an arbitrary point, transport itself to another machine, and...
Emergency medical response requires timely and efficient assessment and treatment of casualties. Mass casualty situations, in particular, strain the resources of emergency responders, prompting the need for a well-organized, effective, automated...
The integration of visual and auditory events is thought to require a joint representation of visual and auditory space in a common reference frame. We investigated the coding of visual and auditory space in the lateral and medial intraparietal...
Many organisms recognize and respond to categories: predator, prey, rival, or juvenile. Organisms recognize these ecologically-important categories by assessing diverse sensory stimuli. A primary focus of my research has been understanding how...
Solar (Computer architecture). ; Ubiquitous computing. Sensor networks. ; Detectors. ; User interfaces (Computer systems).
The complexity of developing context-aware pervasive-computing applications calls for distributed software infrastructures that assist applications to collect, aggregate, and disseminate contextual data. In this dissertation, we present a Context...
We expect wireless body-area networks of pervasive wearable devices will enable in situ health monitoring, personal assistance, entertainment personalization, and home automation. As these devices become ubiquitous, we also expect them to...
Visual searches for a conjunction of features (e.g., a particular combination of color and shape) are ordinarily slow and difficult. However, search efficiency for a particular conjunction can improve dramatically within a few hundred practice...
Multimodality imaging is becoming the standard of care for research and clinical studies. Such an approach is able to provide complementary information which can detect and characterize tumors. Advancing instrumentation for diffuse near-infrared...
Recent studies demonstrating that eye position modulates auditory responses in a brainstem auditory structure and in primary auditory cortex (Groh et al., 2001; Werner-Reiss et al., 2003a), suggest preparation of the auditory signal for eventual...
Single cycle electromagnetic pulses have been difficult to experimentally generate and to theoretically analyze. With the recent development of terahertz systems based on near infrared femtosecond lasers it has become possible to perform single...
Psychopaths. Personality and emotions. Emotions and cognition.
Research investigating clinical and criminal psychopaths is quite extensive. Though it has evolved in terminology over the years, the basic premise and description of psychopathy has maintained deficits associated with emotional interpretation and...
Magnetoencephalography -- Technique.; Magnetic susceptibility.
The measurement of human brain function is the goal of many noninvasive medical imaging modalities. Two sources of physiological contrast are commonly targeted to achieve this goal. The most direct approach to measuring neuronal activity is with...
There is a growing demand for power-constrained sensors in many areas, particularly in emerging healthcare and next-generation biomedical applications. Such sensors have very limited power budget, among which interface circuits, including analog...
Violent video games are immensely popular among children and adults, making it crucial to understand how these games affect the thoughts, feelings, and behaviors of those who play them. The present research proposed an account by which video game...
Problem Statement Patient safety in the modern hospital is supported by multiple human and technological systems, and this type of high-risk/high-complexity domain requires multiple layers of protection against harm. This fault-tolerant approach is...
Smartphones we carry everyday represent the first truly context-aware mobile device. By embedding specialized sensors and pushing AI into phones, it is now possible to continuously sense and infer people's physical activities, social interactions,...
