The analysis of chaotic attractor generation is given, and the generation of novel chaotic attractor is introduced in this paper. The underlying mechanism involves two simple linear systems with onedimensional, two-dimensional, or three-dimensional space functions. Moreover, it is demonstrated by simulation that various attractor patterns are generated conveniently by adjusting suitable space f...

OBJECTIVE Optimal self-care is crucial in patients with chronic heart failure (HF). While the focus of research has been on negative mood states, adequate psychological resources may be required to successfully engage in HF self-care. Therefore, the longitudinal associations of multiple positive affect measures in explaining HF self-care including consulting behavior were examined while adjusti...

In this paper we introduce a simple, computationally inxepentsive, adaptive recursive structure for enhancing bandpass signals highly corrupted by broad-band noise. This adaptive algorithm, enhancing input signals, enables us to estimate the center frequency and the bandwidth of the input signal. In addition, an important feature of the proposed structure is that the conventional bias existing ...

A newly designed printed slot antenna is presented that incorporates variable two band-notched functions for ultra-wideband (UWB) applications. The two band notches of this coplanar waveguide (CPW) fed antenna are achieved by an M-shaped slot (MSS) embedded in the radiating element and a C-shaped strip (CSS) close to ground plane, therefore two very narrow rejected properties in the wireless lo...

The core of building bionic eye system is to imitate the function of human eye neural circuit so as to design the corresponding control strategy. In this paper, fuzzy adaptive PID control method is adopted to realize the function similar to vestibular nucleus’. Besides, the transfer function of controlled object is established according to medical research so as to determine the variation range...

The vision of ubiquitous computing is about numerous devices embedded in our every-day environment, designed to serve humans in a nonobtrusive manner while minimizing the required user attention. These devices are expected to seamlessly monitor context changes and adapt their behavior and functionality to maximize the user benefit. However, designing the selfadaptive logic of such systems is fa...

In a semiorthogonal Lanczos algorithm, the orthogonality of the Lanczos vectors is allowed to deteriorate to roughly the square root of the rounding unit, after which the current vectors are reorthogonalized. A theorem of Simon 4] shows that the Rayleigh quotient | i.e., the tridiagonal matrix produced by the Lanczos recursion | contains fully accurate approximations to the Ritz values in spite...

conclusions self-care education can improve self-care behavior in women with gestational diabetes and it is also effective in impaired glucose tolerance. results after adjusting for the baseline score, the mean score of self-care behaviors was significantly higher in the intervention group than the control group four weeks after the intervention [adjusted mean difference: 19.5; 95% confidence in...
