The amygdala (AMG) has long been viewed as the gateway to sensory processing of emotions and is also known to play an important role at the interface between cognition and emotion. However, the debate continues on whether AMG activation is independent of attentional demands. Recently, researchers started exploring AMG functions using dynamic stimuli rather than the traditional pictures of facia...

Event Mining discovers information in a stream of data, or events, and delivers knowledge in real-time. Our event processing engine consists of a network of event processing agents (EPAs) running in parallel that interact using a dedicated event processing infrastructure. EPAs can be conngured at run-time using a formal pattern language. The underlying infrastructure provides an abstract commun...

Meeting the needs of people with severe to profound hearing loss places enormous demands on a hearing instrument system. It has to make the most of narrowed residual dynamic range and the hearing instrument needs to accommodate marked individual differences in the optimal amplification strategy for compensating for severe to profound hearing loss. There also must be flexibly adjustable protecti...

form for representation of both material and information processing. lhditional modelling languages from the information systems field are inappropriate for capturing realworld dynamics because they put more emphasis on the modelling of static aspects than dynamic aspects, or because they are usually limited to modelling information processing, not the processing of material. This paper addreaa...

Biological vision systems are capable of discerning detail as well as detecting objects and motion in a wide range of highly variable lighting conditions that proves challenging to traditional cameras. In this paper, the authors describe the real-time implementation of a biological vision model using a high dynamic range video camera and a General Purpose Graphics Processing Unit. The effective...

Energy efficiency and energy-proportional computing have become major constraints in the design of modern exascale platforms. Dynamic Voltage and Frequency Scaling (DVFS) is one of the most commonly used and effective techniques to dynamically reduce power consumption based on workload characteristics. The focus of this paper is to survey several energy saving strategies designed for improving ...

This paper presents a novel illumination technique for image processing in environments which are characterized by large intensity fluctuations and hence a high optical dynamic range (HDR). This proposal shows how by combining a set of images, flashed with different radiant intensities but with a constant exposure time for the imager, a single image can be produced with a compressed dynamic ran...

In this paper, a wideband receiver with high dynamic range is proposed. At the front end of the proposed receiver, a sensing waveform is used to sense the input signal. And by adjusting the sensing waveform so as to project the interference to zero, the receiver can eliminate the strong interference signal adaptively before sampling. Both the theoretic analysis and simulation show that this met...

High dynamic range (HDR) rendering is becoming an increasingly popular technique in computer graphics. Its challenge consists in mapping the resulting images’ large range of intensities to the much narrower ones of the display devices in a way that preserves contrastive details. Local tone mapping operators effectively perform the required compression by adapting the luminance level of each pix...
