Recent years have observed a tremendous shift from the technology-centric assessment to the user-centric assessment of network services. Obviously, a sustainable network management approach cares about the user demands and expectations. Consequently, the measurement and modeling of Quality of Experience (QoE) attracted many contributions from researchers and practitioners. Generally, QoE is ass...

Huang Beckman Institute University of Illinois Champaign-Urbana, IL 61801 Email: [email protected] , [email protected] , [email protected] ABSTRACT In the following paper we introduce an algorithm for automatic head tracking using a model-based approach. The input to the system is a 2D video sequence of a head-and-shoulders scene and the output is the traj...

When experimenting with different graphics algorithms and their effects one has to write a lot of code in order to fully exploit today’s graphics hardware. Over the last years there have been some attempts to provide support for this recurring task. A well known example is the nVidia Effect Browser, which can be used as a testbed for numerous purposes. However it provides only limited support w...

The study and modeling of driver’s gaze dynamics is important because, if and how the driver is monitoring the driving environment is vital for driver assistance in manual mode, for take-over requests in highly automated mode and for semantic perception of the surround in fully autonomous mode. We developed a machine vision based framework to classify driver’s gaze into context rich zones of in...

The ribonucleoprotein telomerase synthesizes telomeric DNA by copying an intrinsic RNA template. In most cancer cells, telomerase is highly activated. Here we report a telomerase-based antitumor strategy: expression of mutant-template telomerase RNAs in human cancer cells. We expressed mutant-template human telomerase RNAs in prostate (LNCaP) and breast (MCF-7) cancer cell lines. Even a low thr...

A series of structurally related ansamycins have been analyzed, in a new immobilized template assay, to determine the mechanism by which they inhibit a ribonucleic acid-directed deoxyribonucleic acid (DNA) polymerase from Moloney murine leukemia virus. By this assay, we can better correlate specific structures of these drugs with inhibitory mechanisms. Using an immobilized template, we were als...
