use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems is not an accurate approach; because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study, the infiltration parameters were determined under real conditions of a center pivot system. for this purpose, a single ri...

in order to study the effects of different irrigation system and different amounts of nitrogen fertilizer on yield and quality of sugar beet, an experiment was conducted at ekbatan research station, hamedan during 2005-2006 as split plot based on randomized complete block design  with three replications. the main plots were irrigation systems (furrow, sprinkler and drip irrigation) and subplots...

The main aim of this paper is to propose a state of art wireless sensor technology in agriculture, which can show the path to the rural farming community to replace some of the traditional techniques. In this project, the sensor motes have several external sensors namely leaf wetness, soil moisture, soil pH, atmospheric pressure sensors attached to it. Based on the value of soil moisture sensor...

The problem. We study a new geometric optimization problem which arises in carrot crop management [10], as well as wireless network design and various other facililty location problems. The task is to select a number of locations t j for the sprinklers, and assign a radius r j to each sprinkler. A carrot pi is covered iff it is within range of some transmission point t ji , i.e., d(t ji , pi) ≤...

Fire phenomena are complex and involve non-linear interactions between environmental and fire parameters. Computer based methods (Field model and Zone models), by use of numerical methods applyied on mathematical models in the form of differential equations have been widely used for predicting the results of fire phenomena. In the present work an Artificial neural network (ANN) model has been u...

The world is severely affected by the Covid-19 pandemic health-care workers are hostile to work inside of COVID-19 hospital due social distancing. Supplying essentials food and delivering medicine in hospitals has a challenge. To address need World health organization certified sanitizing system solution for personnel surface decontamination. overcome problem developed automatic portable equipm...

Three test-plot series have been performed to gather information on runoff of sulfonamides from manured arable and grassland after sprinkler irrigation. To prepare test slurries with defined aged residues, liquid bovine manure was fortified with sulfadiazine, sulfadimidine, and sulfamethoxazole and stored short-term. After test-slurry application, the arable land was treated by soil cultivation...

We present here the design and fabrication of a self-powered and autonomous fringing field capacitive sensor to measure soil water content. The sensor is manufactured using a conventional printed circuit board and includes a porous ceramic. To read the sensor, we use a circuit that includes a 10 kHz triangle wave generator, an AC amplifier, a precision rectifier and a microcontroller. In terms ...

We determine the number of minimal degree covers odd ramifica- tion for a general curve.

A blind box economy has emerged in 2019, reflecting new consumption psy-chology among the young Z generation. Based on previous studies Customer Perceived Value (CPV), customer satisfaction, and loyalty, this study analyzes 12 characteristics, 5 CPV, loyalty via questionnaires interviews. Better-Worse Coeffi-cient analysis, characteristic, Kano attribute classification of CPV are used to determ...
