The ABS control problem is described, with a discussion on relevant hybrid control aspects. Next, we comment on conventional ABS design methods and present some new ideas and results on model-based ABS control design that relies on elements of hybrid control.

A cosine-function-based approximation method is proposed to reconstruct atrial fibrillatory wave in QRST intervals for estimating dominant frequency of atrial fibrillation (AF) using single-lead ECG. It is hypothesized that atrial fibrillatory waves in two adjacent QRST intervals can be approached by a cosine function and direct component. As harmonics of dominant frequency are neglected, the d...

This is an Australian Bureau of Statistics (ABS) response to Madden et al.’s paper entitled ‘Estimating Indigenous life expectancy: pitfalls with consequences’, which is published in this issue of the Journal of Population Research. This paper is a critique of the method used by the ABS for compiling life tables for Aboriginal and Torres Strait Islander Australians. The paper claims that ‘the A...

The fluorescent leprosy antibody absorption (FLA-ABS) test was improved by absorbing the serum with suspensions of BCG and M. vaccae. This test was positive in nearly 100% of patients with bacteriologically positive forms of leprosy and in approximately 80% of tuberculoid cases but negative in 18 patients with pulmonary tuberculosis, in 50 healthy noncontacts, and in 136 of 138 non-leprosy pati...

OBJECTIVES We sought to test the hypothesis that autoantibodies (Abs) produced against sarcolemmal Na-K-ATPase play a role in the development of ventricular tachycardia (VT) and cardiac sudden death in patients with dilated cardiomyopathy (DCM). BACKGROUND Autoimmunity is one of the mechanisms of pathogenesis of DCM as well as virus infection and genetic predisposition. METHODS One hundred ...

‎The ABS methods‎, ‎introduced by Abaffy‎, ‎Broyden and Spedicato‎, ‎are‎‎direct iteration methods for solving a linear system where the‎‎$i$-th iteration satisfies the first $i$ equations‎, ‎therefore a‎ ‎system of $m$ equations is solved in at most $m$ steps‎. ‎In this‎‎paper‎, ‎we introduce a class of ABS-type methods for solving a full row‎‎rank linear equations‎, ‎w...

BACKGROUND Stress-induced cardiomyopathy (SCM) is characterized by apical ballooning on echocardiography, but some of SCM patients show non-apical involvement and their characteristics are not well defined. METHODS We investigated 56 patients that were diagnosed as SCM and divided them into 2 groups: apical ballooning syndrome (ABS, n = 49, 87.5%) and non-apical ballooning syndrome (N-ABS, n ...

anti-lock braking system (abs) which is a nonlinear and time variant system may not be easily controlled by classic control methods. this is due to the fact that classic linear controllers are just capable of controlling a specific plant in small region of state space. to overcome this problem, a more powerful control technique must be employed for complex nonlinear plants. fuzzy controllers ar...

BACKGROUND Acute brainstem syndrome (ABS) may herald multiple sclerosis (MS), neuromyelitis optica (NMO), or occur as an isolated syndrome. The aquaporin 4 (AQP4)-specific serum autoantibody, NMO-IgG, is a biomarker for NMO. However, the role of anti-AQP4 antibody in the conversion of ABS to NMO is unclear. METHODS Thirty-one patients with first-event ABS were divided into two groups accordin...

INTRODUCTION Hearing protection devices are one of the primary noise reduction tools in developing countries. This study is intended to produce and apply acrylonitrile butadiene styrene (ABS)/clay nanocomposites to fabricate a laboratory single cup earmuffs and then compare it with double cup and single cup pure ABS earmuffs in terms of noise attenuation performance and comfort. In addition, th...
