Sound source localization using a two-microphone array is an active area of research, with considerable potential for use with video conferencing, mobile devices, and robotics. Based on the observed time-differences of arrival between sound signals, a probability distribution of the location of the sources is considered to estimate the actual source positions. However, these algorithms assume a...

We installed a field experiment to support the development of protocols to restore longleaf pine (Pinus palustris Mill.) to existing mature loblolly pine (P. taeda L.) stands at Camp Lejeune, NC. Seven canopy treatments included four uniform and three gap treatments. The four uniform treatments were defined by target residual basal area (BA) [control (uncut), BA9, BA4.5, and BA0 (clearcut) m2/h...

The concept of stochastic-based accuracy and its calculation procedure for the case of corrective maintenance in data reconciliation-based systems were recently presented [Bagajewicz, M. (2005b). On a new definition of a stochastic-based accuracy concept of data reconciliation-based estimators. In: Proceedings of the 15th European symposium on computer-aided process engineering; Bagajewicz, M.,...

Rectus sheath hematoma is an uncommon and frequently misdiagnosed cause of acute abdominal pain3. Although the exact incidence is unknown, Klingler et al.6 observed 23 cases (1.8%) of rectus sheath hematoma among 1257 patients evaluated by ultrasound for acute abdominal disorders. It is defined as spontaneous in patients without history of abdominal trauma. In these cases, anticoagulation thera...

In an effort to minimize environmental degradation caused by the intensive use of agrochemicals, European Union adopted regulations relevant to afforestation and set aside of agricultural land. The multifunctional role of agriculture enhanced through these regulations and provided adequate motives for a change in the conventional land uses. Cultivators/investors that are interested in afforeste...

We suggest that some extrasolar planets . 60 M will form substantially from silicon carbide and other carbon compounds. Pulsar planets and low-mass white dwarf planets are especially good candidate members of this new class of planets, but these objects could also conceivably form around stars like the Sun. This planet-formation pathway requires only a factor of two local enhancement of the pro...

Coalescing compact binaries are thought to be involved in a wide variety of astrophysical phenomena. In particular, they are important sources of gravitational radiation for both ground-based and space-based laser-interferometer detectors, and they may be sources of supernova explosions or gamma-ray bursts. Mergers of two white dwarfs may produce neutron stars with peculiar properties, includin...

Astronomical observations provide evidence of extrasolar planets. Planets orbiting a star other than the Sun were first discovered in 1992. Wolszczan & Frail (1992) found a periodic delay in the pulses of the radio emission from a pulsar, indicating that two planetary-mass objects orbit a pulsar PSR 1257+12. Since then, more than 240 extrasolar planets have been found. As discussed below, extra...
