In this paper a simple and efficient framework for single human action recognition is proposed. In two parallel processing streams, motion information and static object appearances are gathered by introducing a frame-by-frame learning approach. For each processing stream a Random Forest classifier is separately learned. The final decision is determined by combining both probability functions. T...

In this paper, the problem of frame synchronization in orthogonal frequency division multiplexing (OFDM) system is considered. For an OFDM system, frame synchronization is achieved by forcing the receiver to start its FFT at the right time. One way in which this may be achieved is to precede the OFDM data with a special synchronization symbol. Two synchronization symbols are proposed to achieve...

We propose a new algorithm to induce inversion transduction grammars, in which a crosslingual semantic frame based objective function is injected as confidence weighting in the early stages of statistical machine translation training. Unlike recent work on improving translation adequacy that uses a monolingual semantic frame based objective function to drive the tuning of loglinear mixture weig...

We propose modeling time series by representing the transformations that take a frame at time t to a frame at time t+1. To this end we show how a bi-linear model of transformations, such as a gated autoencoder, can be turned into a recurrent network, by training it to predict future frames from the current one and the inferred transformation using backprop-through-time. We also show how stackin...

There is a discrepancy in the literature as to whether fasting during Ramadan affects athletic performance. We suggest in this letter that the time frame for training is a confounding variable that has been missed in the literature.

To overcome the shortcomings of low transmission rate due to limited bandwidth in traditional wired transmission, this paper proposes a wireless downhole transmission system based on optical OFDM technique. This system is advantageous in both optical communications technique and OFDM technique. It has higher transmission rate. Furthermore, in order to overcome the defects of being sensitive to ...
