The Rise of All-Band All-Mode Radio

چکیده
Wireless communication is an essential component of public safety operations [1,2]. First responders have benefited from many technical advances in the wireless arena in recent years including new modes for voice and data communications, cellular and satellite communications, and wireless local area networks (WLAN). At the same time, this profusion of new technology has aggravated a looming crisis of interoperability. Incompatible equipment, rigid and fragmented spectrum allocations, and continuing reliance on proprietary and “closed” systems are some of the key problems preventing seamless communications among first responders [3].

Dual-Band Evanescent-Mode Substrate Integrated Waveguide Band-pass Filter for WLAN Applications
A new multi-layer substrate integrated waveguide (SIW) structure is developed to design dual-band evanescent-mode band-pass filters (BPFs). Two independent series LC circuits are implemented by incorporating metallic irises in the different layers of the structure. The combination of the metallic irises with capacitive-plates is embedded inside the SIW to independently excite two evane...
متن کاملSiesmic Assessment og Ductility and Strength Capacities of Low-Rise R. C. Buildings
This paper presents a methodology for the assessment of ductility and strength capacities in low-rise buildings. This method utilizes the characteristics of force-displacement for the lowest story level or considers the weakest story in any given low-rise building for its primary analysis. Calculations are based on two levels of earthquake motions, namely strong earthquakes (PGA=0.3 g), and ver...

متن کاملTWO-STAGE METHOD FOR DAMAGE LOCALIZATION AND QUANTIFICATION IN HIGH-RISE SHEAR FRAMES BASED ON THE FIRST MODE SHAPE SLOPE
In this paper, a two-stage method for damage detection and estimation in tall shear frames is presented. This method is based on the first mode shape of a shear frame. We demonstrate that the first mode shape slope is very sensitive to the story stiffness. Thus, at the first stage, by using the grey system theory on the first mode shape slope, damage locations are identified in shear frames. Da...

متن کاملThe Effects of Strained Multiple Quantum Well on the Chirped DFB-SOA All Optical Flip-Flop
In this paper, based on the coupled-mode and carrier rate equations, a dynamic model and numerical analysis of a multi quantum well (MQW) chirped distributed feedback semiconductor optical amplifier (DFB-SOA) all-optical flip-flop is precisely derived. We have analyzed the effects of strains of QW and MQW and cross phase modulation (XPM) on the dynamic response, and rise and fall times of the ...
