This paper proposes a soft sensor to estimate phase flow rates utilizing common measurements in oil and gas production wells. The developed system addresses the limited production monitoring due to using common metering facilities. It offers a cost-effective solution to meet real-time monitoring demands, reduces operational and maintenance costs, and acts as a back-up to multiphase flow meters....

Soft sensors are increasingly gaining wide popularity in industrial processes. They are becoming essential tools that contribute to building ultimately optimised and fully controlled plants due to the soft sensor’s ability to address numerous hardware sensor problems. Gaussian processes are among the techniques recently utilised for soft sensor building. This research reviews the use of this te...

With the Fourth Industrial Revolution, many factories aim for efficient mass production, and robots are being used to reduce human workloads. In recent years, field of gripper with a soft structure that can grip move objects without damaging them has attracted considerable attention. This paper proposes variable-stiffness gripper, based on previous designs, an added silicone coating increased f...

The main objective in refining units is to keep the product quality within specifications in the faces of disturbances. Online measurements of product composition using composition analyser are neither easy nor economically viable. In an effort to overcome these difficulties various soft sensors are designed in the recent years. In this research work, the authors have proposed the design of neu...

In biopharmaceutical process development and manufacturing, the online measurement of biomass and derived specific turnover rates is a central task to physiologically monitor and control the process. However, hard-type sensors such as dielectric spectroscopy, broth fluorescence, or permittivity measurement harbor various disadvantages. Therefore, soft-sensors, which use measurements of the off-...

A sensor management system based on soft computing techniques has been developed and implemented in the flight control system of a small commercial aircraft. Unlike in the conventional sensor management system, the signals from sensors are assigned weights based on fuzzy membership functions and the consolidated signal is computed as a weighted average. This approach improves the quality of the...

Abstract In this paper, we will propose a simple contact model of a soft fingertip based on geometrical analysis and statics of the fingertip. First, we introduce a virtual spring system to the soft fingertip corresponding to one and twodimensional contact between a planar object and a soft fingertip. Second, we describe pressure distribution, and estimate that equation by simulating and measur...

Soft-sensors for estimating in real-time important quality variables are a key technology in modern process industry. The successful development of a soft-sensor whose performance does not deteriorate with time and changing process characteristics is troublesome and only seldom achieved in real-world setups. The design of soft-sensors based on local regression models is becoming popular. Simpli...
