Abstract In order to fulfill the rapid increasing demands of the broadband multimedia and wireless communication, the Multi-input multi-output (MIMO) technique serving as one of the key technologies of the physical layer, have drawn a lot of attention in the past few years. Multi-user multiple-input multiple-output (MU-MIMO) wireless communication system has rapidly gained in popularity over th...

This paper presents the analysin ,design and implementation of a high voltage ratio topology of DC-DC converter. The DC-DC converter has high voltage ratio with reduced input current, output voltage and output current ripple, and also reduces the voltage and current rating of power electronics components and compared with conventional boost converter. The voltage stress on the switches are  red...

Noise problems in signals have gained huge attention due to the need of noise-free output signal in numerous communication systems. The principal of adaptive noise cancellation is to acquire an estimation of the unwanted interfering signal and subtract it from the corrupted signal. Noise cancellation operation is controlled adaptively with the target of achieving improved signal to noise ratio....

A hybrid Multi-Stage Flash–Humidification Dehumidification (MSF-HDH) desalination system is investigated for energy recovery from an MSF system. The MSF-HDH increases total productivity and performance ratio reduces brine rejection. Hot condensed steam that leaves the heater used to warm rejected pretreated a higher temperature suitable HDH operation (about 60 °C). This allows us increase produ...

Migrating archival description from paper-based finding aids to structured online data reconfigures the dynamics of representation and interactions. This paper considers knowledge implications transferring traditional Discover Archives, a university-wide implementation Access Memory (AtoM) at University Toronto. The migration translation varied descriptive practices conform single system that i...

In recent years, vertical-cavity surface-emitting lasers (VCSELs) operating in a single transverse mode have gained a growing interest in many optical fields like spectroscopy, imaging and sensing. Usually, to achieve single-mode emission in conventional oxideconfined VCSELs, the active diameter is typically scaled down to a few micrometers (≤ 4μm) which limits the optical output power. Further...
