introduction:expensive chemical tests are usuallyapplied to control the efficiency of wastewater treatment plants. however, the cost of measuring these parameters is one of the challenges of the wastewater treatment plants. using statistical methods has been evaluated for possibility of calculating expensive parameters by measuring the inexpensive parameters in this study. methods:initial sampl...

MPEG Spectral Band Replication (SBR) is the newest compression technology available as part of the MPEG standards. It is combined with MPEG Advanced Audio Coding (AAC) and improves coding efficiency by more than 30%. The resulting scheme is called High-Efficiency AAC (HE AAC). This presentation explains MPEG SBR and its integration into the existing MPEG-4 bitstream format. The SBR technology i...

A two-stage upflow anaerobic sludge blanket (UASB) and sequencing batch reactor (SBR) system was introduced to treat landfill leachate for advanced removal of COD and nitrogen at low temperature. In order to improve the total nitrogen (TN) removal efficiency and to reduce the COD requirement for denitrification, the raw leachate with recycled SBR nitrification supernatant was pumped into the fi...

MPEG’s low-delay audio codecs AAC-LD and AACELD are capable of providing natural audio in perceptually high quality with an algorithmic system delay1 in the range from 20 to 46.9 mS. The AAC-ELD scheme, in particular, which is basically formed out of AAC-LD and SBR, produces high-quality wideband audio at bit rates between 24 kbps and 48 kbps maintaining a relatively low algorithmic delay of 31...

A decision support system for wastewater treatment plant (WASDA) was developed to make appropriate decisions on plant design and process selection. WASDA mainly focused on municipal and industrial applications to produce conceptual and process design for primary, secondary and advanced treatments. It consists of multiple modules such as equalization tank, coagulation, neutralization, convention...

Imaging studies are necessary prior to subthalamic deep brain stimulation (STN-DBS). Dopamine transporter (DAT) imaging is a powerful tool for visualizing dopamine terminals in the striatum, but its usefulness in STN-DBS is unclear. Here, we retrospectively investigated the relationship between motor symptoms and the specific binding ratio (SBR) on DAT imaging in patients with Parkinson's disea...
