This paper proposes a method based on epoch parameters for detection of creaky voice in speech signal. The epoch parameters characterizing the source of excitation considered in this work are number of epochs in a frame, strength of excitation of epochs and epoch intervals. Analysis of epoch parameters estimated from zero-frequency filtering method with different window sizes is carried out. Di...

This paper examines load sharing and job scheduling in a network of workstations (NOW). Along with traditional methods of load sharing and job scheduling, it also examines methods referred to as epoch load sharing and epoch scheduling respectively. Epoch load sharing evenly distributes the load among workstations with job migration that occurs only at the end of predefined intervals. The time i...

OBJECTIVE To examine the effects of accelerometer epoch lengths, wear time (WT) algorithms, and activity cut-points on estimates of WT, sedentary behavior (SB), and physical activity (PA). METHODS 268 7-11 year-olds with BMI ≥ 85th percentile for age and sex wore accelerometers on their right hips for 4-7 days. Data were processed and analyzed at epoch lengths of 1-, 5-, 10-, 15-, 30-, and 60...

Multi-stage magmatic events associated with large tungsten-tin polymetallic deposits in the Nanling Range have been subject of extensive research spanning many years. In this paper we report results a systematic study petrology, whole-rock geochemistry, zircon U-Pb chronology, and trace element geochemistry granite bodies exposed Xianghualing ore field. They show that granites area are characte...

BACKGROUND It is important to determine if rates of survival and major neurodevelopmental impairment in extremely low gestational age newborns (ELGANs; infants born at 23-27 weeks gestation) are changing over time. METHODS Study infants were born at 23 to 27 weeks of gestation without congenital anomalies at a tertiary medical center between July 1, 1990 and June 30, 2000, to mothers residing...

Currently, this Advanced Track is abbreviated while addressing mainly the concept of energy rate density—a numerical quantity proposed as a useful complexity metric for an underlying, unifying process that guides the origin, evolution, and destiny of all organized systems across the arrow of time, from big bang to humankind. In the summer of 2014, this supplement will grow dramatically, providi...

In this paper we propose a simple, alternative interpretation of backpropagation learning. We call this the “epoch interpretation of learning” and show how it can be used to improve the performance of earlystopping based techniques used for improving generalization performance in neural networks. Experiments performed on noisy, non-linear foreign exchange rate data demonstrate that networks bui...

We use a semi-analytic model of galaxy formation in hierarchical clustering theories to interpret recent data on galaxy formation and evolution, focussing primarily on the recently discovered population of Lyman-break galaxies at z ≃ 3. For a variety of cold dark matter (CDM) cosmologies we construct mock galaxy catalogues subject to identical selection criteria to those applied to the real dat...
