Bursty and out-of-order tuple arrivals complicate the process of determining the content and boundary of sliding windows. To process windows over such streams, two issues need to be addressed: how to sort input tuples efficiently and how to estimate punctuations. In this paper, we focus on these issues to process sliding windows efficiently and accurately over disordered streams. Regarding the ...

We describe a new adaptive multiwindow Gabor expansion, which dynamically adapts the windows to the signal’s features in time-frequency space. The adaptation is based upon local time-frequency sparsity criteria, and also yields as by-product an expansion of the signal into layers corresponding to different windows. As an illustration, we show that simply using two different windows with differe...

The use and features of UltraEdit, a powerful and practical Program Editor application, are described for creating, editing and saving SAS program code when working on the PC and remote servers. UltraEdit is a Windows application, which runs on a PC and has a familiar and user-friendly interface. It has common for Windows-editors features like text highlighting with the mouse and shift-arrow ke...

In this paper, an efficient face recognition system based on sub-window extraction algorithm and recognition based on principal component analysis (PCA) and Back propagation algorithm is proposed. Our proposed method works on two phases: Extraction phase and Recognition phase. In extraction phase, face images are captured from different sources and then enhanced using filtering, clipping and hi...

We analytically investigate univariate C continuous cubic L1 interpolating splines calculated by minimizing an L1 spline functional based on the second derivative on 5-point windows. Specifically, we link geometric properties of the data points in the windows with linearity, convexity and oscillation properties of the resulting L1 spline. These analytical results provide the basis for a computa...

We have created a publicly-available implementation of IPv6 for Windows NT. Because we have made our source code available, we hope that our implementation can serve as a base for networking research and supply sample code for other implementations. In this paper we describe our solutions for several problems that any network protocol implementation for Windows NT will encounter. Based on our e...

The advent of open source software leading to Beowulf clusters has enabled small to medium sized Higher and Further education institutions to remove the “computational power” factor from research ventures. In an effort to catch up with leading Universities in the realm of research, many Universities are investing in small departmental HPC clusters to help with simulations, renders and calculati...

In our previous research, we compared the actual route recorded by a GPS device “PhotoTrackr” and the optimal vehicle route derived by using ArcGIS Network Analyst tool. VRP is the fundamental problem in the research fields of transportation, we focus on variations of CVRPTW (Capacitated VRP with Time Windows). Various types of VRP are studied to determine the optimal route under various constr...

The correspondence problem is one of main topics in stereo vision that, despites being studied for many years, is still in progress. In this paper, we present a new method that computes the disparity map. Our method is local (i.e. only information gathered in the close neighborhood is used) and is based on image statistics. More specifically it combines multiple adaptive windows and local stati...

It can be observed that most sophisticated kernel mode rootkits implement hiding tasks via loading drivers in Windows. Also, more and more malware writers are taking advantage of rootkits to shield their illegal activities. Therefore, the role of a detector for effectively detecting Windows driver-hidden rootkits is becoming extremely important. In our previous work, we focused on developing a ...
