abstract = {The objective of this study was to obtain a suboptimal temperature trajectory to maximize fresh weight (W_F) and harvested fruit weight (W_HF) of tomato (Solanum lycopersicum L.) using the Monte Carlo method. To achieve this objective, we posed a problem of dynamic optimization based on a non-linear dynamic crop growth model under greenhouse conditions. In the solution of this problem temperature restrictions are used in the range of 15 ºC to 30 ºC, which represents the mean temperature range during the day in the city of Saltillo. Optimization is done considering prediction horizons of 15 min in an interval of 120 d after transplant (dat) and using a dynamic mathematical tomato (Solanum lycopersicum L.) growth model evaluated in a chapel-type greenhouse in Saltillo, Coahuila (〖25〗^0 〖25〗^' 〖36〗^'' N, 〖100〗^0 59'44''W). The suboptimal temperature trajectory that maximizes fruit weight (W_F) was determined for the entire simulation time interval (0 to 120 dat). Moreover, the suboptimal temperature trajectory that maximized fruit weight (W_F) during pre-harvest (0 to 58 dat) and harvested fruit (W_HF) as of the beginning of harvest (day 59), described by the model until the end of simulation (120 dat). The results obtained show that the suboptimal temperature trajectory from day 59, which marks the beginning of harvest, was established around 15 ºC to maximize W_F and around 30 ºC for maximization of〖 W〗_F and W_HF. It could also be observed that the suboptimal temperature trajectory for both cases shows periods that emulate day and night, 15 ºC to 30 ºC, before day 59. The results obtained permit us to propose conditions for either maximizing fruit on the plant or harvested fruit, and the resulting temperature trajectories can be used to obtain a softened curve with more stable cycles that can be put into practice. },

abstract = {This paper proposes a nonlinear synchronization controller for a swarm of unicycle robots performing a cooperative task, i.e., following a desired trajectory per robot while maintaining a prescribed formation. The effect of communication between robots is analyzed and several network topologies are investigated, e.g., all-to-all, ring type, undirected, among others. The stability analysis of the closed loop system is provided using the Lyapunov method. Experiments with four unicycle robots are presented to validate the control law and communication analysis. Accumulated errors over the experiment time are presented in order to determine which topology is most efficient.},

abstract = {This study verified the concentration over time of nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur (N, P, K, Ca, Mg, and S) in the leaves, stems, fruits, and roots of tomato plants. An indeterminate growth variety with ball-type fruits suited for greenhouse cultivation was used. The results showed that the distribution of minerals in the different organs of the plant varies over time. The minerals N, P, and K showed a tendency to decrease their concentration, while the concentration of Ca and S increased and that of Mg remained constant over time. The leaves had the highest concentrations of N, P, K, Ca, and Mg. The concentrations of K, for both leaf and stem, ranged between 20 and 30 g kg¡1. N and K were the most extracted minerals, while P was the least extracted mineral. The information presented in this paper allows a better fertilization plan for growing tomatoes inside greenhouses.

abstract = {This brief proposes a hierarchical control scheme based on the definition of a set of multirobot task functions. To deal with the inherent conflicts between tasks, a strict hierarchy is imposed on them. We present a novel scheme that copes with two main difficulties shared in standard task-based controllers: 1) to impose a desired time convergence of tasks and 2) to avoid discontinuous task transitions occurred when a task is inserted or removed in the hierarchical structure. As a result, continuous input references are generated for the low-level control of the group. The validation is achieved in simulation and by performing an experiment with wheeled mobile robots.},

(ii) An on-line/off-line learning and testing method, showing that robots can acquire a useful knowledge base without human intervention to learn and reproduce bead geometries. And finally, (iii) an on-line testing analysis including penetration of the bead, that is used to train an artificial neural network (ANN). For the experiments, an optic camera was used in order to measure bead geometry (width and height). Also real-time computer vision algorithms were implemented to extract training patterns. The proposal was carried out using an industrial KUKA robot and a GMAW type machine inside a manufacturing cell. We present expermental analysis that show different issues and solutions to build an industrial adaptive system for the robotics welding process.},

abstract = {Water utilization by crops, namely tomato, within greenhouses is one of the most significant factors indetermining yield. Daily water consumption by tomato plants were calculated, to determine the actualevapotranspiration and transpiration rates, as well as the incorporation measurement of climatic variables andweekly determinations of fresh and dry weights of the plants. Estimations of daily evapotranspiration andtranspiration rates by the tomato plants were calculated using multiple regression models. The best models forestimating, both the evapotranspiration and transpiration, had adjusted R2 values greater than 0.9. Using themultiple obtained regression models it is possible to estimate the water needs of tomato plants under greenhouseconditions from readily available variables. The aim of this study was to generate regression models in order todetermine the crop water requirements of greenhouse tomato. [ABSTRACT FROM AUTHOR]},

abstract = {Tomato is one the most important vegetables worldwide and mineral nutrition in tomato crops is considered as the second most important factor in crop management after water availability. Mathematical modeling techniques allow us to design strategies for nutrition management. In order to generate the necessary information to validate and calibrate a dynamic growth model, two tomato crop cycles were developed. Several mineral analyses were performed during crop development to determine the behavior of N, P, K, Ca, Mg and S in different organs of the plant. Regression models were generated to mimic the behavior of minerals in tomato plants and they were included in the model in order to simulate their dynamic behavior. The results of this experiments showed that the growth model adequately simulates leaf and fruit weight (EF \> 0.95 and Index \> 0.95). As for harvested fruits and harvested leaves, the simulation was less efficient (EF \< 0.90 and Index \< 0.90). Simulation of minerals was suitable for N, P, K and S as both, the EF and the Index, had higher values than 0.95. In the case of Ca and Mg, simulations showed indices below 0.90. These models can be used for planning crop management and to design more appropriate fertilization strategies.},
