“…The author M. Zagirnyak, P. Kostenko have presented an external optimization of SQL-query under conditions of databases structural uncertainty [5] they have used a LMCP algorithm which is a local model of controlled process which allow the rationality and the correctness of the process thus getting the query optimized by developing the mathematical model of IS. The proposed approach for the particular tumor images which is based on the concept of details of the image and textual features and hence they have proved the results based on these concept.…”

Data storage and retrieving the data on a specific time frame is critical for any application today. So an efficiently designed query lets the user get the results in the desired time and creates the credibility for the corresponding application. Here in this paper various techniques which are currently used or proposed in recent years and to get a better perspective in this field of query optimization are explored. Automatic external SQL-query optimization method is where the principle of building queries regardless of applied database management system and its settings is explored. It would be interesting to explore the work of authors where they have proposed the energy-efficient query processing and optimization based on a database accelerator.

“…In Reluctance synchronous wind generator design optimisation in the megawatt, medium speed range [13], a different coil configuration on the rotor is implemented in wind energy conversion systems in medium speed ranges. Finally, in Genetic algorithms in design of a synchronous reluctance motor [14], genetic algorithms (GA) are used to optimize the rotor structure of a synchronous reluctance motor from its basic un-predetermined geometry.…”

This paper presents an approach to minimize the electromagnetic torque ripple of a synchronous reluctance generator (SynRG) with a magnetic field created by externally excited rotor coils. The synchronous reluctance machine is widely used in low and medium power systems such as wind power generation and new electric vehicle technologies. This paper proposes a rotor topology with flux barriers and direct current excited coils that reduce the torque ripple and replace the permanent magnets used in other reluctance rotor topologies. First, the initial rotor design, without excitation coils, is optimized to obtain a new rotor structure that reduces the electromagnetic torque ripple. In this work, the optimization of the rotor geometry was achieved by using genetic algorithms and the finite element method to optimize and parameterize the main components of the machine. In the optimized rotor model, an external electronic converter is included to feed the coils positioned between the magnetic flux barriers and the segments formed by the ferromagnetic material of the rotor. Finally, the electrical and magnetic machine variables obtained from implementing the coils into the optimized rotor are compared to the initial rotor structure operating under nominal load conditions to demonstrate the advantage of this topology in minimizing the electromagnetic torque ripple.
