A deterministic optimal design problem for the heat equation [PDF]

open access: yes, 2016
For the heat equation on a bounded subdomain $\Omega$ of $\mathbb{R}^d$, we investigate the optimal shape and location of the observation domain in observability inequalites.

Room Temperature Controller with ON/OFF Display

open access: yesinternational journal of engineering technology and management sciences, 2022
The main purpose of this Room Temperature Controller is to control the temperature of the room or any closed spaces whose temperature keeps fluctuating and thus requires a constant watch on the temperature of the room. The use of this system eliminates constant watching on the device by self controlling the temperature of the system.

Networking Nanoswitches for ON/OFF Control of Catalysis

open access: yesJournal of the American Chemical Society, 2017
The nanoswitches 1 and 2 are interdependently linked in so-called network states (NetStates). In NetState I, defined by presence of [Cu(1)]+ and 2, the organocatalyst N-methylpyrrolidine catalyzes a conjugate addition. Addition of iron(II) ions as an external chemical trigger to NetState I discharges Cu+ from [Cu(1)]+.

Model Predictive Control Structures for Periodic ON–OFF Irrigation

open access: yesIEEE Access, 2023
Agriculture accounts for approximately 70% of the world’s freshwater consumption. Furthermore, traditional irrigation practices, which rely on empirical methods, result in excessive water usage. This, in turn, leads to increased working hours for irrigation pumps and higher electricity consumption.
