A kinematics model that describes not only the motion but also the geometric variations of LTS is developed. Through error analysis of the proposed model, it is claimed that gimbals axis misalignments and tracking mirror center offset are the key contributor to measuring errors of LTS. A self-calibration method is presented to calibrate LTS with planar constraints. Various calibration strategie...

This note details the infrastructure deployed and developed at the University of California at Santa Barbara (UCSB) to handle the construction of CMS Silicon Tracker modules for the outer barrel and endcap. Capacity has been developed to assemble and wirebond 15 modules per day and in addition to wirebond 30 hybrids. Early results and experiences of production are also given. In the £rst substa...

People tracking is one major part of visual surveillance systems. A number of different people trackers exist nowadays. One of those multi-people trackers is the Reading People Tracker. It consists of four individual co-operating tracking modules. Weaknesses of one module are thereby compensated by the strengths of another one. The Motion Detector performs background-foreground segmentation to ...

In this article, a fuzzy logic solar tracker was designed and implemented to increase the efficiency of photovoltaic system by updating position panel throughout day for optimal use radiation. design implementation tracker, different control strategies were analyzed, concluding that satisfies all requirements with developed prototype underwent tests in determined period time validate performanc...

In this paper, we describe a new methodology for tracking a user’s areas of interest on a computer screen. In contrast to costand analysis-intense eye-tracking studies, our approach operates on a software-only basis that requires no additional hardware. In an exploratory study, we compared our software-based tracker with hardware eye trackers with respect to the types of recorded data. Interest...

During the high luminosity phase of the LHC (HL-LHC), the machine is expected to deliver an instantaneous luminosity of 5× 10 cm−2s−1. A total of 3000 fb−1 of data is foreseen to be delivered, with the opening of new physics potential for the LHC experiments, but also new challenges from the point of view of both detector and electronics capabilities and radiation hardness. In order to maintain...

PURPOSE To describe recent technological additions to the NIDEK CXIII and Quest excimer lasers. METHODS A summary article with data from previous published studies outlining the benefits of newer technology. RESULTS The addition of a 1-kHz infrared eye tracker decreased the spread of laser spot placement from a mean of 228.79 microm without a tracker to 38.47 microm with the eye tracker. Th...

Eye tracking technologies offer sophisticated methods for capturing humans’ gaze direction but their popularity in multimedia and computer graphics systems is still low. One of the main reasons for this are the high cost of commercial eye trackers that comes to 25,000 euros. Interestingly, this price seems to stem from the costs incurred in research rather than the value of used hardware compon...

This paper analyzes the behavior of a variety of tracking algorithms for single layer threshold networks in the presence of random drift. We use a system identiication model to model a target network where weights slowly change and a tracking network. Tracking algorithms are divided into conservative and nonconservative algorithms. For a random drift rate of , we nd upper bounds for the general...

This paper develops a novel linear quadratic observer and tracker for the linear sampled data regular system with a direct transmission term from input to output. At the beginning, we use some existing techniques to decompose the singular system into an equivalent regular system which has a direct transmission term from input to output. Then, based on this equivalent regular system, a high-gain...
