We study and analyze the computational complexity of a software-based H.264/AVC (advanced video codec) baseline profile decoder. Our analysis is based on determining the number of basic computational operations required by a decoder to perform the…

Video transmission in wireless environments is a challenging task calling for high-compression efficiency as well as a network friendly design. Both have been major goals of the H.264/AVC standardization effort addressing "conversational" (i.e.,…

In this paper we apply the so-called Hachtel's augmented matrix method for solving linear least squares problems to static state estimation. This method does not seem to have been applied in power system state estimation by others. The test system…

This paper presents an analysis of player behavior in a Massively Multiplayer Online Role-Playing Game (MMORPG). We examine player behavior in terms of when, how much, and what they do in the virtual world. Player behavior is described through…

An important challenge faced by many teachers as they involve students in science investigations is measuring ("assessing") students' progress. Our detailed requirements analysis in a particular school district led to the idea that teachers need…

Linguistic fuzzy modeling in high dimensional regression problems is a challenging topic since conventional linguistic fuzzy rule-based systems suffer from exponential rule explosion when the number of variables and/or data examples becomes high. A…

This paper addresses the problem of selecting contact locations for grasping objects in the presence of shape and contact location uncertainty. Focusing on two-dimensional planar objects and two finger grasps for simplicity, we present a principled…

In the early stage of floorplan design, many modules have large flexibilities in shape (soft modules). Handling soft modules in general nonslicing floorplan is a complicated problem. Many previous works have attempted to tackle this problem using…

When searching for sensor data, sensor instances, or Sensor Web Enablement (SWE) services the description of the observed phenomenon plays an important role. Obviously, every user searching for sensor data needs to specify in which kind of sensor…

For quick access to new handwritten collections, current handwriting recognition methods are too cumbersome. They cannot deal with the lack of labeled data and would require extensive laboratory training for each individual script, style, language,…

A dual-task paradigm with two primary tasks (visual and haptic) combined with two secondary tasks (visual and haptic) was used to assess visual-haptic working memory (WM) in young adults, older healthy adults, and mild cognitive impairment (MCI)…

In virtual MAD environment the most significant phase is the A/D process (Assembly/Disassembly). The effectiveness of the maintenance scheme depends on the A/D sequence, number of gripper changes and the path used in an A/D procedure. However, in a…

Haptic interaction between people and machines might benefit from an understanding of haptic communication between one person and another. We recently reported results showing that two people performing a physically shared dyadic task can outperform…
