Carrier tracking in GNSS receivers suffers in environments where platform dynamics, received noise and interference are expected simultaneously. Similar is the case of a Locata receiver which operates on the same basic principles as GNSS receivers. A reduction in tracking loop bandwidth may offer noise rejection, but at the same time it makes tracking more vulnerable to oscillator and platform ...

Computational approaches to tune the activation of intracellular signal transduction pathways both predictably and selectively will enable researchers to explore and interrogate cell biology with unprecedented precision. Techniques to control complex nonlinear systems typically involve the application of control theory to a descriptive mathematical model. For cellular processes, however, measur...

Logical reasoning is at the heart of math courses. Wason’s selection task has been widely investigated to examine students’ reasoning; however, previous studies found that few participants could correctly solve Wason’s tasks. This study adopted a modified format of the selection task, context-embedded problems, as well as the standard selection tasks to look into high school and college student...

Studies show that people can recognize their own movements, such as their own walking (presented in silhouette using point lights), their own drawing (presented as a moving point light), own clapping, and their own piano playing. We extend this result to proprioceptive control, showing that people can recognize their own eye movements, when presented as just a point moving against a black backg...

This paper considers the location-tracking problem in PCS networks. Solutions to this problem in fact highly depend on the mobility patterns of mobile subscribers [ACM DIAL-M (1999) 72]. In the literature, many works have assumed a simple random walk model, where mobile subscribers always stay in a roaming state and can move in any direction with equal probability. In this paper, we propose a n...

A renewable energy source plays an important role in electricity generation. Various renewable energy sources like wind, solar, geothermal, ocean thermal, and biomass can be used for generation of electricity and for meeting our daily energy needs. Energy from the sun is the best option for electricity generation as it is available everywhere and is free to harness. On an average the sunshine h...

In this paper, we propose a global optimal fuzzy tracking controller, implemented by fuzzily blending the individual local fuzzy tracking laws, for continuous and discrete-time fuzzy systems with the aim of solving, respectively, the continuous and discrete-time quadratic tracking problems with moving or model-following targets under finite or infinite horizon (time). The differential or recurs...
