Precision fertilization is a major constraint in consistently balancing the contradiction between land resources, ecological environment, and population increase. Even more, it popular technology used to maintain sustainable development. Nitrogen (N), phosphorus (P), potassium (K) are main sources of nutrient income on farmland. The traditional fertilizer effect function cannot meet conditional...

Abstract The two-wheeled self-balancing robot (TWSBR) is based on the axletree and inverted pendulum. Its balancing problem requires a control action. To speed up response of minimize steady state error, in this article, grey wolf optimizer (GWO) method proposed for TWSBR space feedback technique. controller stabilizes minimizes overshoot value system. dynamic model system derived Euler formula...

The scope of this paper is to forecast wind speed. Wind speed, temperature, wind direction, relative humidity, precipitation of water content and air pressure are the main factors make the wind speed forecasting as a complex problem and neural network performance is mainly influenced by proper hidden layer neuron units. This paper proposes new criteria for appropriate hidden layer neuron unit’s...

Foresight of CO2 emissions from fuel combustion is essential for policy-makers to identify ready targets effective reduction plans and further improve energy policies plans. A new method forecasting the future development China’s proposed in this paper by using grey theory. Although existing fractional nonlinear Bernoulli model (denoted as FNGBM(1,1)) has been theoretically proven enhance adapt...

Abstract With the development of energy Internet, integrated network electricity-gas interconnection has become an important research object optimization. To improve absorption capacity and utilization efficiency renewable in a regional network, comprehensive multi-objective optimization model containing power to gas (P2G) is proposed this paper. The considers two objectives pollutant emission ...

The grey wolf (Canis lupus) is one of the most widely distributed terrestrial mammals, and its distribution and ecology in Europe and North America are largely well described. However, the distribution of grey wolf in southern China is still highly controversial. Several well-known western literatures stated that there are no grey wolves in southern China, while the presence of grey wolf across...

Three-diode model (TDM) of photovoltaic (PV) cells is a significantly precise that addresses the electrical and optical losses in such PVs. Due to its nonlinearity multivariable characteristics, TDM complex debatable PV model. This article proposes novel hybrid African vultures–grey wolf optimizer (AV–GWO) approach precisely estimate parameters TDM. The AVO meta-heuristic inspired by vultures’ ...

Localization is crucial to wireless sensor networks. Among the recently proposed localization algorithms, mobile anchor-assisted (MAL) algorithm seems promising. A MAL using a single anchor has low energy consumption but high error. Conversely, with three or more anchors minor errors consumption. By balancing and accuracy, our study developed assisted by two anchors. traverses network along dou...
