Multipulse excited linear predictive coding (MPELPC) is a good medium bit-rate speech coding technique. However, due to the enormous processing required for searching the pulse information (pulse positions and amplitudes), many practical implementations of multipulse coders actually utilize some simplified pulse search algorithms such as dropping the amplitude optimization during the search for...

This paper describes a data acquisition system developed to solute the problem of different data acquisition modules communication in ubiquitous industrial environment. The system can allow faster reconfiguration of plant-floor networks as applications change. It can achieve higher throughput, lower average message delay and less average message dropping rate in wireless communication. The deve...

Binder-free MXene films comprising Ti3C2Tx nanoflakes in a face-to-face fashion, achieved by a simple dropping-mild baking approach, exhibit high gravimetric capacitances up to 499 F g(-1) with excellent cyclability and rate performances. The entire electrode system including Ni-foam and MXene film shows volumetric capacitances in the range of 84-226 F cm(-3) depending on the loadings of MXene ...

Mammalian herbivores may incidentally ingest plant-dwelling insects while foraging. Adult pea aphids (Acyrthosiphon pisum) avoid this danger by dropping off their host plant after sensing the herbivore's warm and humid breath and the vibrations it causes while feeding. Aphid nymphs may also drop (to escape insect enemies), but because of their slow movement, have a lower chance of finding a new...

The pea aphid Acyrthosiphon pisum : Harris (Hemiptera: Aphididae) is a phloem-feeding insect whose antipredator defenses include kicking, walking away, and dropping from the plant. Aphid dropping, a risky and energetically costly antipredator behavior, can be increased by the release of aphid alarm pheromone; there is also evidence that insect density and plant health can affect the likelihood ...

We experimentally demonstrate an optical node with time-space-and- wavelength domain contention resolution, deflection and dropping capability. The node is composed of an optical buffer based on an optical crossconnect and a wavelength converter. Although the experimental results are shown at 10 Gbit/s the bitrate can be increased substantially. Bit-error rate measurements are shown, sustaining...

The effects joined by vehicular mobility are investigated in the performance analysis of cellular network. The channel holding times induced from mobility and call holding time are approximately modeled by general distribution to reflect an actual situation. We propose an iterative numerical algorithm to compute the performance values of the CAC as the values for a handoff call dropping probabi...

This paper presents two analytical models for TCP Reno and TCP Tahoe. For each model an algorithm is derived to calculate the utilizations and packet drop rates. The accuracy of the models is verified by comparing the calculated results versus simulation results. These results show that the TCP Reno is superior to Tahoe by having higher percentage of utilization and lower percentage of packet d...
