Full charge capacity (FCC) refers to the amount of energy a battery can hold. It is the fundamental property of smartphone batteries that diminishes as the battery ages and is charged/discharged. We investigate the behavior of smartphone batteries while charging and demonstrate that the battery voltage and charging rate information can together characterize the FCC of a battery. We propose a ne...

Communication from a low-to a high-level system without acknowledgements will be unreliable; with acknowledgements, it can be insecure. We propose to provide quantiiable security, acceptable reliability, and minimal performance penalties by interposing a device (called the Pump) to push messages to the high system and provide a controlled stream of acknowledgements to the low system. This paper...

Ireland developed a National Strategy 2030 that argued for the creation of a new form of higher education institution, a Technological University. The research reported here reviews the first stage of this partnership development. The study found that national policy can create system capacity and change, but that individual partners may have more to gain or lose in collaborating. When presente...

We investigate the capacity of three symmetric quantum states in three real dimensions to carry classical information. Several such capacities have already been defined, depending on what operations are allowed in the protocols that the sender uses to encode classical information into these quantum states, and that the receiver uses to decode it. These include the C1,1 capacity, which is the ca...

The North American freight railroad network is projected to experience rising transportation demand in the coming decades, leading to increased congestion on many rail lines. Capacity is further strained by increased interest in increasing the speed and frequency of passenger service on shared rail corridors. Since passenger trains in North America predominantly operate on corridors where freig...

In this paper we evaluate performance of the vertical BLAST (VBLAST) receiver algorithm in multipletransmitter/multiple-receiver (MTMR) cellular WCDMA systems. We assume that the VBLAST algorithm is executed on a symbol level (i.e, on the despreaded received signal), following a conventional bank of matched filters (correlators). Also, we introduce concept of virtual antennas. BER performance o...
