Nowadays, interest in electric propulsion is increasing due to the need to decarbonize society. Electric drives and their components play a key role in this electrification trend. The electrical machine, in particular, is seeing an ever-increasing development and extensive research is currently being dedicated to the improvement of its efficiency and torque/power density. Among the winding methods, hairpin technologies are gaining extensive attention due to their inherently high slot fill factor, good heat dissipation, strong rigidity, and short end-winding length. These features make hairpin windings a potential candidate for some traction applications which require high power and/or torque densities. However, they also have some drawbacks, such as high losses at high frequency operations due to skin and proximity effects. In this paper, a multi-objective design optimization is proposed aiming to provide a fast and useful tool to enhance the exploitation of the hairpin technology in electrical machines. Efficiency and volume power density are considered as main design objectives. Analytical and finite element evaluations are performed to support the proposed methodology.

In order to meet the multifarious needs for drug information and to cope with the post-marketing surveillance of drugs adequately, an on-line drug information network, which is composed of two data bases, clinical case record data base and literature data base, has been developed. Primary considerations in designing these systems were input of clean data, accurate input, insuring that no ADRs are overlooked, accumulation of the latest data, saving manpower required for processing, and processing large quantities of data. This system is also designed to input and to output in Japanese character.

A drug information system (DARIS) has been created for handling reports on suspected drug reactions. The system is suitable for being run on desktop computers with a minimum of hardware requirements: 187 K read/write memory, flexible or hard disc drive and a thermal printer. The data base (DRUG) uses the QUERY and IMAGE programming capabilities for data entry and search. The data base to statistics link program (DBSTAT) enables data transfer from the data base into a file for statistical analysis and signalling suspected adverse drug reactions.The operational, medical and statistical aspects of the general population voluntary adverse drug reaction monitoring programme—recently initiated in the State of Kuwait—are described.
