automatically configure the FPTA in tens to hundreds of seconds, time in which evaluates-100,OOO circuit candidate solutions. The paper details several examples of evolutionary synthesis of analog circuits on the FPTA. Evolved circuits include rectifier circuits, reconfigurable amlog filters and reconfigurable

language. The algorithm constructs the parsing graph and re-configures it dynamically using a set of reversible Markov chain jumps. This computational framework integrates two popular inference approaches -- generative (top-down) methods and discriminative (bottom-up) methods. The former formulates

Decimation filter is used to reduce the sampling rate for succeeding stages of an oversampling ADC. The speed of a successive-approximation ADC predominately depends on the decimator speed. This necessitates a need to design a high speed decimation filter to improve the overall system performance

Abstract. Distributed R-trees (DR-trees) are appealing infrastructures for im-plementing range queries, content based filtering or k-NN structures since they inherit the features of R-trees such as logarithmic height, bounded number of neighbors and balanced shape. Interestingly, the mapping

Reconfigurable optical filters are of great importance for applications in optical communication and information processing. of particular interest are tuning techniques that take advantage of mechanical deformation of the devices, as they offer wider tuning range. Here we demonstrate

Abstract — In this work, the design procedure, modelling and implementation of reconfigurable filters based on RF microelectromechanical systems metamaterials is presented. Specifically, tunable stop-band and pass-band frequency responses are obtained by combining RF-MEMS with metamaterials based

to my family... A current focus among communication engineers is to design flexible radio sys-tems to handle services among different telecommunication standards. Thus, low-cost multimode terminals will be crucial building blocks for future generations of multimode communications. Here, different bandwidths, from different telecom-munication standards, must be supported. This can be done using multimode transmultiplexers (TMUXs) which allow different users to share a common chan-nel in a time-varying manner. These TMUXs allow bandwidth-on-demand. Each user occupies a specific portion of the channel whose location and width may vary with time. Another focus among communication engineers is to provide various wideband services accessible to everybody everywhere. Here, satellites with high-gain spot beam antennas, on-board signal processing, and switching will be a major comple-mentary part of future digital communication systems. Satellites provide a global

Software-based Network Intrusion Detection Systems (NIDS) often fail to keep up with high-speed network links. In this paper an FPGA-based pre-filter is presented that reduces the amount of traffic sent to a software-based NIDS for inspection. Simulations using real network traces and the Snort

Abstract—This paper presents a novel design scheme for tunable coplanar waveguide components with applications to compact lumped-element MEMS reconfigurable filters. Shunt MEMS switches are employed for tuning the values of lumped components frequently encountered in microwave integrated circuits
