The effectiveness of greenhouse control can be improved by the application of model based intelligent control. Such control requires a good model of the greenhouse. For a large variety of industrial or recreational greenhouses the derivation of an analytical model is not feasible therefore black-box modeling has to be applied. Identification of black-box models requires large amount of data fro...

In Sweden, the number of datacenters establishments are steadily increasing thanks to green, stable and affordable electricity, free air cooling, advantageous energy taxes and well-developed Internet fiber infrastructures. Even though datacenters use a lot of energy, the waste heat that they create is seldom reused. A possible cause is that this waste heat is often low grade and airborne: it is...

The conservation of insect pollinators is drawing attention because of reported declines in bee species and the 'ecosystem services' they provide. This issue has been brought to a head by recent devastating losses of honey bees throughout North America (so called, 'Colony Collapse Disorder'); yet, we still have little understanding of the cause(s) of bee declines. Wild bumble bees (Bombus spp.)...

The paper presents a service robot for health monitoring and localized chemical, drugs and fertilisers dispensing to plants in greenhouses. The robot and its end-effectors have been conceived and designed specifically oriented to the served environment and tasks. A virtual prototype has been realized.

The paper reflects topicality of the use geometric ornaments in design jewellery. stepwise process constructing a girih ornament 3D modelling program is illustrated detail on example twelve-fold star rosette, as well obtaining three-dimensional product from linear cloisonne and stained-glass enamelling techniques. variants ornamental compositions different shapes complexity obtained simple modu...

AURORA has been conceived in order to substitute hard and unhealthy human work inside greenhouses by means of an autonomous mobile robot outfitted with appropriate sensors and operation devices. Emphasis has been put in the development of a new robotic platform specifically designed for greenhouse tasks, governed by a control architecture that supports both autonomous navigation and shared huma...

Using the usual definitions of information and entropy in quantum gravity and statistical mechanics and the existing views about the relation between information and complexity, we examine the evolution of complexity in an ever expanding universe.

On 3rd October 2002, the youngest German national holiday was celebrated in Berlin: day of unity. This newly established (having begun 1991) is meant to commemorate reunification Germany which took place on 1990. A state-ceremony opera house and a street held at Pariser Platz around Brandenburg Gate. The most important symbolic center re-unified city turned into grounds for huge open-air festiv...

temperature and humidity are two important parameters affecting the quality and quantity of greenhouse products so two double greenhouses were manufactured in 3.5, 40 and 11 m in height, length and width respectively in agricultural research center of jiroft and kahnooj to study these effects. both of greenhouses are similar in materials, final height, gutter height, covering and field operatio...

Tuta absoluta (Meyrick), a leafminer that damages tomato leaves, terminal buds, flowers, and fruits, is destructive pest responsible for 80–100% of yield losses globally. Different insect species have different courtship responses phototropic flight rhythms. Improving the trapping effects sex pheromone light traps important constructing an IPM system T. absoluta. The present study explored hour...
