The concentration of nitrate (NO3-) in Narragansett Bay has been shown to undergo considerable temporal and spatial variation. However, the dynamics of this flux has never been monitored on a fine-scale (
Tato práce uvádí do problematiky automatických zavlažovacích systémů a poskytuje stručný přehled komerčních řešení. Dále jsou uvedeny stručně zdroje vody závlahy a jednotlivé komponenty nezbytné pro návrh automatického systému. V další části práce je popsán zavlažovací systém na pozemku v Praze, dále je navržena řídicí jednotka zajišťující jak ovlá...
Tato práce se zabývá problematikou návrhu a konstrukce chladicí komory s Peltierovými články. V práci jsou popsány základní fyzikální principy a jevy související s Peltierovým článkem, jenž byl při realizaci výroby chladicí komory stěžejní. V práci je podrobně rozebrán návrh mechanické konstrukce chladicí komory a řídicí elektroniky včetně řídicího...
Drought is the most severe problem for agricultural production, and the intensity of this problem is increasing in most cultivated areas around the world. Hence improving water productivity is the primary purpose of sustainable agriculture. This study aimed to use cloud IoT solutions to control a modern subsurface irrigation system for improving ir...
Abstract This work presents the development, analysis and comparison of dynamic models, to implement in a simple way a filtering and control system for a quadcopter through the use of a microcontroller. A non-linear dynamic model obtained from the Euler Lagrange equations is approached; also a simplified non-linear model from the first model and a ...
Osnovna ideja je bila izdelava VU metra, ki zajema signal s pomočjo vgrajenega mikrofona ali avdio vtičnice. Za procesiranje signala sem uporabil mikrokrmilnik Teensy 3.2 skupaj z dodatno avdio ploščo za hitrejše procesiranje podatkov. Teensy se programira v okolju »Arduino Sketch«, ki temelji na programskem jeziku »C++«. Za prikaz sem uporabil dva...
This thesis introduces an advanced control strategy for a DC/DC interleaved boost converter. A plain version of a controller imposes equal power distribution among the converter’s legs. Though, it does not assure the highest efficiency during the converter operation. This issue is addressed by implementing a controller that adjusts the number of ac...

Dates are subjected to postharvest losses in quality and quantity caused by water loss, fermentation, insect infestation, and microbial spoilage during storage. Cold storage is the main element in the postharvest quality management used for fruit preservation. Although cold storage is used for dates, precision control of the relative humidity (RH) ...
Pooling different renewable energy sources (hydrogen, solar, wind, geothermal, etc.) enables developing a standalone energy micro-grid. The energy flows from these various sources are neither constant nor equivalent. Therefore, control and balancing mechanisms should be established for optimal energy utilization through an intelligent system based ...
