In this paper, a simple method to obtain a notch in the ultra-wideband (UWB) bandpass filter is presented. UWB bandpass filter is designed using ground plane aperture technique. To reject the undesired wireless local area network (WLAN) signals, a complementary single split ring resonator (CSSRR) is placed under the coupled lines of the bandpass filter. The CSSRR has flat insertion loss and goo...

PURPOSE Filter devices are already employed for the protection of carotid, coronary and renal distal vascular bed during endovascular procedures. This is a pilot study investigating their feasibility, safety and distal emboli protection capability during recanalization of lower extremities' acute and subacute occlusions. MATERIALS AND METHODS Study population included 16 patients, 11 with a s...

In this paper, we address the overlooked problem of CrossSite Scripting (XSS) on mobile versions of web applications. We have surveyed 100 popular mobile versions of web applications and detected XSS vulnerabilities in 81 of them. The inspected sites present a simplified version of the desktop web application for mobile devices; the survey includes sites by Nokia, Intel, MailChimp, Dictionary, ...

 Brain-computer interfaces (BCI) record brain signals, analyze and translate them into control commands which are relayed to output devices that carry out desired actions. These systems do not use normal neuromuscular output pathways. Actually, the principal goal of BCI systems is to provide better life style for physically-challenged people which are suffered from cerebral palsy, amyotrophic l...

Background: Peritoneal dialysis (PD) is an efficient alternative for hemodialysis. Removal of waste metabolites and excess water from the blood circulation are the two main tasks done during dialysis. These are done by using a filter; in PD, the naturally semi-permeable peritoneal membrane acts as the filter. Automated PD machines control intelligently the operations to enhance the efficiency a...

The advent of digital storage of audio signals and the availability of high-speed digital signal processing devices facilitate the implementation of high-order filter functions for loudspeaker equalization. A method is presented for generating a digital model of a loudspeaker system from which an efficient compensation filter using an IIR structure is derived. Application of this technique allo...

The development of tunable filters is a key point for the ability of optical telecommunication networks to comply with the continuous evolution of the service providers needs. Among the numerous technologies which can be used to achieve narrow bandpass filtering devices, we concentrate our analysis on Thin-Film Interference Coatings and compare the principles, performances and use constraints o...

We present tapered-slit filter devices for high-throughput viable circulating tumor cell (CTC) isolation and release. The membrane filter having an array of tapered-slits reduces the cell stress concentration at the edge of slit entrance, thus achieving viable CTC isolation with minimal stress. We fabricated the tapered-slit membrane from the UV exposure of spin-coated SU8 layers. The membrane ...

All-pass filters are useful devices that allow phase correction or equalization of signal without introducing any amplitude distortion. We present a new design scheme in which a grating is introduced in the interaction region of the two adjacent microrings in a cascaded multiring structure. The analysis accounts for the counter-directional coupling between the two waveguides. Theoretical analys...

Tunable imaging filters have been used for a variety of science programmes on the Anglo-Australian and William Herschel Telescopes during the last five years. This contribution describes these novel devices and reviews the science (both Galactic and extragalactic) done with them. Possible strategies for implementing a tunable filter at the VLT are also discussed. Significant scientific potentia...
