Markovian System

One main problem of quantum control in quantum systems is the manipulation of states including state transfer and state tracking. We design control fields to realize arbitrary state transfer for open quantum system by Lyapunov stability theory, and investigate the state transfer for non-Markovian system with phase relaxation and energy dissipative relaxation. The numerical simulations illustrate that arbitrary state (eigenstate, superposition state or mixed state) transfer and maintenance for non-Markovian system can be realized under Lyapunov control function by an external steady control field of proper amplitude, with a success rate of more than 98%. When the right control field and function are implemented, not only the decoherence is compensated completely but also the purity of quantum states is maintained in the process of state transfer.

And Control

Efficacy of neem on Citrus Leafminer (CLM) and effect on its parasitoid Ageniaspis citricola was evaluated, using field, cage and olfactometer tests. Treatments were: aqueous extract of neem (50 gL-1), formulated oil of neem (10 mL L-1) and control. Field study was done in a Citrus aurantifolia orchard, three applications were carried out, which were evaluated every 48 hours until ten days after the treatment. Cage and olfactometer tests were performed in a greenhouse and repeated twice each time. In the cage, it were used 50 infested Citrus reticulata plants per experimental unit, while for the olfactometer test, as experimental arena, transparent plastic jars with 20 adults of CLM inside were used. Variables evaluated were: CLM infestation, dead, live and predated larvae, pupae, emerged adults and parasitized pupal chambers. The highest mortality of the CLM was caused by the aqueous extract of neem with 77.17%, which began 48 hours after application, suggesting inhibition of feeding. The aqueous extract of neem showed in average 88.80 % of repellency of adults of CLM and neem oil 85.64%. The high mortality of CLM and the repellent effect of neem, seem to influence negatively in parasitism which fluctuated between 9.45 % and 20.16 % in treated trees.

This article discusses the problem of using touch screens in the crew cockpit as part of a general trend optimizing the humanmachine interface of the cockpit in order to improve the safety and quality of flights. The aim of the work is to develop a promising cockpit information and control field of a transport category aircraft based on touch screens and to analyze the feasibility of using this technology on board the aircraft. Based on the analysis of current research and trends, as well as regulatory documentation in the field of building a perspective cockpit using touch screens, a conclusion is made about the feasibility of using touch screens in the cockpit and the concept of a perspective cockpit is developed. As important elements of the concept, such interactive display pages as normal and emergency checklists, a navigation page with a flight plan, and pages of the aircraft navigation system are considered. Given the well-known problem of using touch displays in turbulence, a backup display and reconfiguration control loop is proposed. On the basis of the above-mentioned concept, an intelligent information system is being developed for prototyping a promising cockpit, taking into account the application of the ARINC 661 standard, with subsequent integration into a universal stand for prototyping the cockpit and testing the results with the participation of flight experts. The practical significance of this study is due to the significant optimization of the elements of the cockpit information and control field, as well as the potential increase in the reliability of the complex by replacing the electromechanical display controls, reducing the cost of developing the information and control field and making improvements, reducing weight by decreasing the number of wires and equipment, reducing the complexity of installation.
