the main task of this work is related with the design of a class of siso robust control law for theregulation of substrate concentration (cdo) of an industrial activated sludge wastewater plant. the controldesign is related with an uncertainty estimator (reduced order observer) based active control. departing from the tracking error between the desired and the current substrate concentrations t...

This paper presents the parameters of permanent magnet synchronous motor i.e. speed (r), stator resistance (RS), q-axis inductance (Lq), and torque (Ts) is to be estimated by using Model Reference adaptive System(MRAS). To improve the performance of speed sensor less permanent magnet synchronous motor drives, especially at low speeds by identifying stator resistance together with speed. Severa...

OBJECTIVES: To determine the prevalence and characteristics of patients who achieved target doses angiotensin converting enzyme inhibitors (ACEIs)/ II receptor blockers (ARBs), beta-blocker, mineralocorticoid antagonists (MRAs). MATERIALS AND METHODS: A retrospective chart review study heart failure with reduced ejection fraction (HFrEF) received ACEIs/ARBs, beta-blockers, or MRAs follow-up mor...

A mutual model reference adaptive system (MRAS) is proposed to implement a position sensorless field-orientation control (FOC) of an induction machine. The reference model and adjustable model used in the mutual MRAS scheme are interchangeable. Therefore, it can be used to identify both rotor speed and the stator resistance of an induction machine. For the rotor speed estimation, one model is u...

Are current economic models well equipped to provide useful policy prescriptions? Many economists would have certainly answered, “yes” before the recent Global Recession. This economic crisis has not only demonstrated the importance of banking and financial markets for the dynamics of real economies. It has also revealed the inadequacy of the dominant theoretical framework. Standard models have...

Previous research shows that people assign latent goals or intentions to simple animated agents based on the motion behavior of these agents. We propose that human observers can infer that an animated agent has a partial state of belief about its environment and that observers use this information – in combination with the agent's observable behavior – to infer its goals. We conducted an experi...

The main consequences of de Sitter Special Relativity to the Standard Model of Physical Cosmology are examined. The cosmological constant Λ appears, in this theory, as a manifestation of the proper conformal current, which must be added to the usual energy–momentum density. As that conformal current itself vanishes in absence of sources, Λ is ultimately dependent on the matter content, and can ...
