The American Thoracic Society/European Respiratory Society Task Force underlined that the use of in-line filters during respiratory function tests "is an area of controversy". The aim of the present study was to measure the contamination occurring during forced expiration downstream from a screen pneumotachograph (SP) with and without an in-line filter (Pall PF30S). A total of 40 healthy subjec...

BrdU infusion into normal cats: Osmotic pumps (ALZET) were filled with 50mg/mL BrdU dissolved in 50% DMSO/50% ddH2O filtered through a sterile 0.22μm filter. Pumps were then incubated in sterile saline at 37 °C overnight prior to insertion. The pumps were surgically inserted subcutaneously just caudal to the scapulae per the protocol approved by IACUC at Temple University. The number of pumps w...

abstract according to the adventages of passive radars they have been reconsidered recently due to development of signal processing technology. in the field of sea targets detection using passive radar few research have been reported. this paper presents a new method to detect sea targets using adaptive filter weights variation model and using the fact that the radar cross section of sea target...

In this paper, a new voltage controlled first order all-pass filter is presented. The proposed circuit employs a single differential voltage dual-X second generation current conveyor (DV-DXCCII) and a grounded capacitor only. The proposed all-pass filter provides both inverting and non inverting voltage-mode outputs from the same configuration simultaneously without any matching condition. Non-...

A new bit-serial architecture for implementation of high order FIR filters, as well as example FPGA and CMOS realizations are introduced. This structure exploits the simplicity of coefficients which consist of two power-of-two terms to yield efficient implementations. Quantization effects are discussed and a simple block scaling method for reducing rounding and truncation noise in high order fi...
