This paper discusses how the switched reluctance generator (SRG) converts mechanical energy from wind via turbine into electrical energy as directed by an electronic controller. Starting with a review of the electromechanical energy conversion principles, the paper examines the implications of the energy conversion process on how the SRG is controlled. The structure of the SRG controller for sp...

Fuzzy control methods are developed for a high efficient variable speed constant frequency power generating system, with wind power generation as an example. In slip power recovery configuration, the system is composed of a doubly excited brushless reluctance machine and a reduced rating power electronic converter unit linking the stator secondary circuit with the power line. The doubly excited...

Recently, many vehicles have applied electric parts for saving fuel consumption and reducing levels of environmental pollution. ISG (Integrated Starter and Generator) system is one of main electric parts of following these trends and can improve fuel efficiency. If ISG motor and inverter are driven by appropriate switching time, it can be a more efficient system operation than existing ISG oper...

Research on bad news delivery reveals a reliable temporal delay in the onset of the bad news message from the sender to the receiver. An experiment utilized a false feedback test design to determine whether the delay is better accounted for by negative verbal message planning, functional communication potential, or both. Participant-senders (N = 138) delivered either scripted or unscripted good...

A reduced order numerical computational method based on flux tube modelling is proposed for the rapid electromagnetic analysis and design of electromechanical energy transducers using an example of a synchronous reluctance machine. The flux tube method is applied to establish flux linkage functions facilitating fast and accurate inductance estimation. The practical advantage is that the approac...

A new zero-current-transition (ZCT) converter for switched reluctance motor drives is presented. The proposed ZCT converter possesses the definite advantages that both the main and auxiliary switches are operating with zero-current switching (ZCS), as well as minimum current and voltage stresses. It has simple circuit topology, minimum component count and low cost. The ZCT technique can signifi...

The standard Engineer-Lawyer problem (Kahneman & Tversky, 1973) points to the failure of reasoners to integrate mentioned base-rate information in arriving at likelihood estimates. Research in this area nevertheless has presupposed that participants respect complementarity (i.e., participants ensure that competing estimates add up to 100%). A survey of the literature leads us to doubt this pre-...

NE OF THE most striking as0 pects of the 1960 election campaign is that it was waged between two comparatively liberal platforms and candidates. It is true that Kennedy carried the standard of a party whose majority is actually liberal, whereas Nixon represented a party which had subscribed to a relatively liberal platfonn (including a rather strong civil rights position) with some reluctance, ...

Results of a study of psychologic environmental factors and their effects on siblings in terms of fear from dental interventions are presented. Thirty pairs of siblings aged 6-15 years, treated at the Zagreb University Institute of Pediatric and Preventive Dental Medicine in Zagreb, were included in the study. The main criterion for inclusion in the study was the fact that one child accepted th...

There are human beings whose psychological capacities are rivalled or exceeded by many non-human animals; such humans are often referred to as 'marginal cases'. R G Frey has argued that there is no secure, non-arbitrary way of morally distinguishing between marginal humans and non-human animals. Hence, if the benefits of vivisection justify such painful and lethal procedures being performed on ...
