A modeling approach to study advanced floating body Z-RAM memory cells is developed. In particular, the scalability of the cells is investigated. First, a Z-RAM cell based on a 50 nm gate length double-gate structure corresponding to state of the art technology is studied. A bi-stable behavior essential for Z-RAM operation is observed even in fully depleted structures. It is demonstrated that b...

This paper describes investigations into the use of ‘excitationsynchronous’ spectral analysis to provide acoustic features for automatic speech recognition. Within each 10 ms frame the region of maximum power is located and used as the centre for the window in a subsequent Fourier transform. The method has been found to be effective in locating stop bursts and vocal-tract responses to glottal c...

A £xed scale (typically 25ms) short time spectral analysis of speech signals, which are inherently multi-scale in nature [7] (typically vowels last for 40-80ms while stops last for 10-20ms), is clearly sub-optimal for time-frequency resolution. In this work, we detect piecewise quasi-stationary speech segments based on the likelihood of that segment which in turn is estimated from the linear pr...

Hundreds of studies have examined how prey animals assess their risk of predation. These studies work from the basic tennet that prey need to continually balance the conflicting demands of predator avoidance with activities such as foraging and reproduction. The information that animals gain regarding local predation risk is most often learned. Yet, the concept of 'memory' in the context of pre...

The treatment of total deafness using a cochlear implant has now become a routine medical procedure. The tendency to expand the audiological indications for cochlear stimulation and to preserve the remnants of hearing has brought new problems. The authors have studied the topographical anatomy of the internal structures of the ear in the area where cochleostomy is usually performed and an impla...

The use of bandwidth smoothing techniques for the delivery of prerecorded compressed video has been shown to be an effective technique in reducing the network bandwidth requirements needed to play back video. Any fixed allocation scheme can affect the ability to allow for VCR functions. In this paper, we examine the impacts that bandwidth smoothing techniques have on the delivery of stored vide...

Window-based elliptic curve multiplication algorithms are more attractive than non-window techniques if precomputation is allowed. Reducing the complexity of elliptic curve point multiplication of the form , which is the dominant operation in elliptic curve cryptography schemes, will reduces the overall complexity of the cryptographic protocol. The wBD is a new window-based elliptic curve multi...

PURPOSE To compare radiation dose and image quality using predefined narrow phase window versus complete phase window with dose modulation during R-R using 320-row MDCTA. METHODS 114 patients underwent coronary CTA study using 320-row MDCT scanner. 87 patients with mean age (61 + 13 years), mean BMI (29 + 6), and mean heart rate (HR) (58 + 7 bpm) were imaged at predefined 66-80% R-R interval ...

This article proposes a DR program characterized by novel compensation scheme. The proposed scheme recognizes the different characteristics of curtailment, such as total length curtailments within window time, or number separate curtailment events (i.e., startup), and compensates end-user accordingly. features piece-wise reward function comprised two intervals. participants receive onetime upfr...

Neural summarization models have a fixed-size input limitation: if text length surpasses the model’s maximal length, some document content (possibly summary-relevant) gets truncated. Independently summarizing windows of size disallows for information flow between and leads to incoherent summaries. We propose windowing neural abstractive (arbitrarily) long texts. extend sequence-to-sequence mode...
