Signal segmentation is a crucial stage in the activity recognition process; however, this has been rarely and vaguely characterized so far. Windowing approaches are normally used for segmentation, but no clear consensus exists on which window size should be preferably employed. In fact, most designs normally rely on figures used in previous works, but with no strict studies that support them. I...

Neural Network approaches to time series prediction are briefly discussed, and the need to specify an appropriately sized input window identified. Relevant theoretical results from dynamic systems theory are briefly introduced, and heuristics for finding the correct embedding dimension, and thence window size, are discussed. The method is applied to two time series and the resulting generalisat...

Term proximity has been successfully used in many entity retrieval searches and enhance the quality of the retrieval systems. In general, the goal of entity searches is to retrieve a ranked list of entities in response to a user’s query. The entities could be organisations, products, location, or people. Some of the proximity models that were successful used association discovery in a window of...

The SFC approach has been widely studied. The conventional television adopted interlaced scanning format to reduce motion artifacts. The converting procedure of interlaced signal into a progressive format is known as format conversion. In this paper, we study directional information and evaluate and compare objective and subjective performances by using widow size.

-The TCP window size value, which is contained in the window size field of the TCP segment is a very important TCP Parameter. The window size value determines the number of bytes of data that can be sent before an acknowledgement from the reciever is necessary. If the window size field value is made too small, the performance deteriorates. This will slow throughput considerably. On the other ha...
