Process operability was originally proposed as an approach for the design and control of complex chemical processes. This approach has been applied to processes that are described by high-dimensional linear models. For nonlinear systems, an operability-based method for design and intensification of low-dimensional membrane reactor systems has also been reported. However, operability algorithms ...

Achieving high performance process control (HPPC) requires that the control system operate the plant at optimal efficiency over the full range of teady state and dynamic conditions. Air separation processes present particular challenges because of their energy intensive nature and demanding roduction schedules. The HPPC challenges for both cryogenic and adsorption processes are presented, recen...

IN WORKING MACHINES the human operator is essential for the performance of the total system. Productivity and energy efficiency are both dependent not only on inherent machine properties and working place conditions, but also on how the operator manoeuvres the machine. In order to operate energy-efficient the operator has to experience the machine as harmonic. This is important to consider duri...

This article aims to build a set of exploratory and strong operability evaluation index system, the collection of 3 cities in zhengzhou to use construction land on the basis of economic efficiency index of related data, the selection of the zhengzhou region as the object of empirical study, using data envelopment analysis (DEA) method), and C squared R dual model, with the help of a DEAP Versio...

Our research goal is to improve stylus operability by utilizing the human knowledge and skills applied when a user uses a pen. Such knowledge and skills include, for example, the way a person holds a pen to apply a generous amount of ink to draw a thick line with a brush pen. We propose a form of interaction, Finger Action, which uses input operations applying such knowledge and skills. Finger ...

Health care integration is an important way to achieve healthy ageing and meet the personalized health needs of elderly. Based on 16 policies introduced at national level in China from 2013 2022, open coding process grounded theory was used set up variable indicators construct a PMC index model for quantitative evaluation policies. The results study show that mean value 7.42, including 12 excel...

OBJECTIVE To determine the extent to which differences in generic quality of life (QOL) between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (AVR) patients explained by EuroSCORE and heart-team operability assessment. METHODS A total of 146 high-risk patients with EuroSCORE > 6 and aged ≥ 75 years underwent TAVI (n = 80) or aortic valve replacement (n =...

Pathologic obstruction of the proximal lumen and secondary atrophy of the media of the peripheral small pulmonary arteries were absolute operative contraindications in cases of VSD and/or PDA with severe pulmonary hypertension. Such patients who were operated on died with no decrease in pulmonary arterial pressure. The index of pulmonary vascular disease (IPVD), a composite and quantitative eva...

“Media” is an artifact that expands our creativity and intelligence. We have been studying the use of “Rich Media” to support creative and intelligent human activities. Specifically, for over ten years we have focused on the 3D space as one of “Rich Media” and developed many 3D sketch systems that support the design of 3D objects. However, their long-term evaluation has revealed that they are n...
