Influence of Time and Length Size Feature Selections for Human Activity Sequences Recognition

Abstract: In this paper, Viterbi algorithm based on a hidden Markov model is applied to recognize activity sequences from observed sensors events. Alternative features selections of time feature values of sensors events and activity length size feature values are tested, respectively, and then the results of activity sequences recognition performances of Viterbi algorithm are evaluated. The […]

Are You In a Calibration Rut?

The process industry has seen impressive technological advances in past years, with the introduction of smart transmitters, documenting calibrators, communicators and robust calibration software. Plants are able to have a fully automated and integrated calibration system. However, evidence indicates that many companies with an existing enterprise system typically have only established (but not updated) a […]

Adaptive Backstepping Sliding Mode Control with Fuzzy Monitoring Strategy for a Kind of Mechanical System

Abstract: A novel adaptive backstepping sliding mode control (ABSMC) law with fuzzy monitoring strategy is proposed for the tracking-control of a kind of nonlinear mechanical system. The proposed ABSMC scheme combining the sliding mode control and backstepping technique ensure that the occurrence of the sliding motion in finite-time and the trajectory of tracking-error converge to equilibrium […]

From Strategy to Execution – Leading Change

“Great leaders… look outward…at the competition, out at the future, out at alternative routes forward. They focus on broad patterns, finding connections, cracks, and then press home their advantage where the resistance is weakest. They must be visionaries, strategic thinkers, activators. When played well, this is without a doubt, a critical role.” —Marcus Buckingham & […]

How to Improve Motor Performance and Lower Downtime

“Approximately one-third of total U.S. delivered energy in 2012, 23.6 quadrillion Btu [British thermal units], was consumed in the industrial sector, which includes manufacturing, agriculture, construction, and mining,” according to the U.S. Energy Information Administration. To put this in perspective, the average annual energy consumption for a U.S. household is roughly 10.8 megawatt hours (MWh) […]

PID Controller Auto-Tuning Based On Process Step Response and Damping Optimum Criterion

Abstract: This paper presents a novel method of PID controller tuning suitable for higher-order aperiodic processes and aimed at step response-based auto-tuning applications. The PID controller tuning is based on the identification of so-called n-th order lag (PTn) process model and application of damping optimum criterion, thus facilitating straightforward algebraic rules for the adjustment of both […]

Project Management Is More Than a Disruption: It Is Real Work

Modern control systems are sophisticated assemblies with varied state-of-the-art technologies. Implementing these systems requires a team of technically gifted technicians and engineers who welcome the challenge of taking the often disparate pieces of a complex system and merging them into an integrated control system. Although these teams can resolve high-tech matters, they do not always […]
