A new approach toward global modeling improvement of active microwave devices using filter-bank transforms is presented. A preconditioner based on these transforms is used to facilitate the iterative solution of the Poisson’s equation. This equation must be solved in the excitation plane which the input voltage is applied, at each time step in the full-wave analysis of high-frequency active dev...

IVC Filter Retrieval. Because retrievable filters often become permanent, the risk-benefit analysis performed prior to placement should involve weighing the long-term consequences of recurrent DVT and IVC thrombosis with reduction in nonfatal PE. Inferior vena cava filters should be used primarily in patients who have acute VTE with an absolutecontraindicationtoanticoagulationandshouldberemoved...

Many researches are about optimizing schemes for packet classification and matching filters to increase the performance of many network devices such as firewalls and QoS routers. Most of the proposed algorithms do not process dynamically the packets and give no specific interest in the skewness of the traffic. In this paper, we conceive a set of selfadjusting tree filters by combining the schem...

We present the fabrication and evaluation of microdebubblers that are able to remove large bubbles while keeping a very low dead volume. The devices use a polytetrafluoroethylene membrane that is permeable to air in order to filter air bubbles out of an aqueous sample. The dead volume of the devices is less than one microliter, but bubbles as large as 60 microliters can be removed. This simple ...

Cell retention devices are used to retain cells in containers during perfusion culture. However, the conventional membrane-based filtration devices have challenges such as membrane fouling/clogging and increased contamination risk due to frequent filter replacements. To solve these challenges, we introduce a new microfluidic cell retention device based on inertial cell focusing. We demonstrated...

Location awareness is a key ingredient to many applications of mobile devices. Devices with the ability to determine their own position can retrieve, filter or present information depending on this position in space. There are, however two different ways to view this situation resulting in different distributions of computational resources. We argue that in many cases it will be better and easi...

Multispectral image capture, unlike traditional RGB imaging, records the colour signals in a scene. Most available devices are either filter-wheel multiple exposure systems or point-measuring diffraction grating based devices. In this article we introduce a 2D matrix, full spectral, single exposure capture system – the Applied Spectral Imaging SpectraCube – which determines multispectral images...

In diagnosis of diseases Ultrasonic devices are frequently used by healthcare professionals. The main problem during diagnosis is the distortion of visual signals obtained which is due to the consequence of the coherent of nature of the wave transmitted. These distortions are termed as ‘Speckle Noise’. The present study focuses on proposing a technique to reduce speckle noise from ultrasonic de...
