A Proportional Integral Derivative (PID) controller is commonly used to carry out tasks like position tracking in the industrial robot manipulator controller; however, over time, PID integral gain generates degradation within controller, which then produces reduced stability and bandwidth. proportional derivative (PD) has been proposed deal with increase but limited if gravity not compensated for. In practice, dynamic system non-linearities frequently are unknown or hard obtain. Adaptive...
The tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is one of the most important pests cotton, Gossypium hirsutum L., that has become resistant to a wide range synthetic insecticides. Cry1Ac-expressing cotton proven its effectiveness against this insect since introduction in North America 1996. However, constant exposure budworm protein toxin may result development resistance it. To estimate frequency alleles confer 1.0 μg Bacillus thuringiensis Cry1Ac diagnostic...
El cogollero del maíz, Spodoptera frugiperda (J.E. Smith), es indudablemente la plaga más importante de este cultivo a nivel mundial. Los maiceros continente americano han batallado con esta por décadas, y sus recomendaciones control se adaptado para África Asia, basadas en resultados contrastantes sobre el impacto producción cuando infesta plantas etapas tempranas. Importantes mecanismos tomar decisión como umbral daño no están completamente desarrollados, aplicación insecticidas aún...
Se considera que la defoliación temprana del maíz (Zea mays L.) disminuye las posibilidades de obtener máximos rendimientos. Sin embargo, estudios diseñados para medir los factores bióticos y abióticos reducen el área foliar han producido resultados contrastantes. Cuando es defoliado antes desarrolle séptima hoja (V7), plantas pueden compensar pérdida sin impactar rendimiento. Setenta cinco por ciento publicaciones proveen información empírica indican severa no afecta rendimiento cuando...
Insects exposed to genetically modified crops expressing Bacillus thuringiensis (Bt) toxins are under intense selection pressure that could result on widespread Bt resistance. Screening for early indications of resistance developing in targeted Lepidoptera is conducted many the regions where cotton and corn have been commercialized. Heliothis virescens (F.) (Lepidoptera: Noctuidae) has selected laboratory a gene Cry1Ac. We used this line test assumptions theoretical predictions related...
La amenaza que representa la inseguridad pública en América Latina ha conllevado muchos de los gobiernos asolados por ella recurran a las políticas militarización. En el caso México, gobierno creó Guardia Nacional para pacificar país. El objetivo del artículo es responder pregunta ¿por qué, pese argumentos y posturas diferentes actores nacionales e internacionales, Administración Federal México (2018-2024) decidió crear una combatir reducir índices violencia? estudio emplea un método...
Assessing the research of individual scholars is currently a matter serious concern and worldwide debate. In order to gauge long-term efficacy efficiency this practice, we carried out limited survey operation outcome Mexico's 30-year old National System Investigators or SNI, country's main instrument for stimulating competitive in science technology. A statistical random sample researchers listed area Humanities Behavioral Sciences-one SNI's first better consolidated academic divisions...
Abstract Corn earworm (Helicoverpa zea) and fall armyworm (Spodoptera frugiperda) are major migratory pests of maize (Zea mays) in the United States Mexico. They primarily controlled with genetically engineered (GE) maize, while 25-yr moratorium on cultivating GE Mexico has forced growers to control these insecticides, where productivity remains 35% below world’s average. The annually exports 5% its grain Mexico, it provides human food animal feed. This seed is often sown by smallholder...
In order to obtain information on the biology of masked chafer Cyclocephala pasadenae (Coleoptera: Scarabaeidae), and determine date when 50% population is captured in light traps, field data were obtained during 4 years Albuquerque, New Mexico. Capture occurred approximately third week July, this one-generation per year insect. To reduce need for intensive sampling a predictable model capture pest, analyzed using trapezoidal numerical integration estimate both lower threshold degree-days...
The tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), is an economically important pest of the Americas. Females this species copulate multiple times during their lifetimes, and presence sperm from males inside them could allow for a diversity paternal genotypes in offspring, unless there was complete precedence first mating. If female copulates with male that insecticide-susceptible another insecticide-resistant, her progeny vary resistance phenotypes. In some cases,...
Abstract. Lane detection is a problem that has attracted in the last years attention of computer vision community. Most approaches used until now to face this combine conventional image processing, analysis and pattern classification techniques. In paper, we propose methodology based on so-called Ellipsoidal Neural Networks with Dendritic Processing (ENNDPs) as new approach provide solution important problem. The functioning performance proposed validated real video taken by camera mounted...
This paper proposes a model of neural network called Morphological-Linear Neural Network (MLNN). The consists on merging two different types layers: hidden layer morphological neurons and an output classical perceptrons. has the ability to separate patterns using hyperboxes hyperplanes part perceptrons, respectively. hybrid is completely trained by stochastic gradient descent. We compared multilayer perceptrons dendrite with this arquitecture. experimental results over 25 real datasets show...
Tobacco budworm, Heliothis virescens (F.) (Lepidoptera: Noctuidae), females can copulate multiple times creating the possibility for sperm competition. We used a colony lacking wild pigmentation on wings (albino-type) an experiment in which double mated. Females copulated 2 days apart with two, 2-day-old males, one albino-type and wild-type, or opposite sequence. A third of produced offspring from first mate, this group was significantly biased toward producing compared to wild-type progeny....
The possible role of pollinators enhancing soybean production has been an ongoing topic study. effect flower visitation, especially by honey bees, Apis mellifera L., in this self-pollinated crop resulted no benefit increasing yield, or at times a significant impact on grain production, differences that might be caused the influence multiple field condition variables. In study, experimental design excludes insects from plants during ∼20-day flowering period was used. Results indicated he...
The tobacco budworm, Heliothis virescens (F.), is thought to be a pest that migrates each year from warmer southern latitudes colder areas where it cannot survive cold temperatures during the winter. Although northwestern Mississippi south of 40° N latitude, which recognized as upper boundary for overwintering survival insect, commonly believed increasing abundance spring in this area because migration moths south. In study we used 10-year set captures budworm male pheromone traps and air...
