The goal of expert-finding is to retrieve a ranked list of people as a response to a user query. Some models that proved to be very successful used the idea of association discovery in a window of text rather than the whole document. So far, all these studies only considered fixed window sizes. We propose an adaptive window-size approach for expert-finding. For this work we use some of the docu...

Metrizamide computed tomography (CT) of the spine allows evaluation of the contents and measurement of the size of intracanalicular structures. The relative size (linear and area measurements) of spinal structures can be changed by varying imaging factors or the density of intrathecal contrast material. Two phantoms, one consisting of rods embedded in a plastic cylinder and the other of a verte...

Media access control plays a critical role in cognitive radio networks (CRNs). In our previous work, we have proposed a fairnessoriented media access control (FMAC) protocol to achieve fair and efficient coexistence of infrastructure-based CRNs. In this paper, we enhance FMAC to be used for coexisting ad hoc CRNs, where no centralized base stations exist, and secondary users (SUs) access channe...

This paper introduces a block based motion estimation algorithm based on projection with adaptive window size selection. The blocks cannot match well if their corresponding 1D projection does not match well, with this as foundation 2D block matching problem is translated to a simpler 1D matching, which eliminates majority of potential pixel participation. This projection method is combined with...

According to the latest version of the IEEE 802.16 standard, the mandatory contention resolution method is the truncated binary exponential backoff, with the initial window size and the maximum window size controlled by the base station. However, the problem of choosing the right set of backoff parameters for the current network level remains unsolved and left as an open issue since this strate...

In this article, we investigate the structure of Croatian linguistic co-occurrence networks. We examine the change of network structure properties by systematically varying the co-occurrence window sizes, the corpus sizes and removing stopwords. In a cooccurrence window of size n we establish a link between the current word and n − 1 subsequent words. The results point out that the increase of ...

We consider the problem of common due window location scheduling on a single machine, where the processing times of jobs depend both on their starting times and positions in a sequence. The problem is to determine the optimal earliest due date, the due window size, and the job schedule simultaneously to minimize costs for earliness, tardiness, earliest due date assignment and due window size pe...

In recent years, there has been an increasing interest in extending stream processing engines with rule-based temporal reasoning capabilities. To ensure correctness, such systems must be able to output results over the partial data received so far as if entire (infinite) had available; furthermore, these streamed out soon relevant is received, thus incurring minimum possible delay; finally, due...
