Technical condition assessment of induction motor can be done with stator current analysis. This analysis can be done in steady state with FFT transform. Starting current analysis with wavelet transform is a very good method of cage condition assessment. The advantage of this method is that we can observe how characteristic components vary in time. Characteristic fault symptoms can be observed when the machine is working with alternating load which causes rotor’s angular speed and slip change. Transient states when the load changes, occur very often increases the application of thism method. This paper presents the results of application wavelet transform in motor fault diagnostics in transient states.

Objectives: To perform a systematic review, and to verify and define deficiencies in literature data on drug policy and management of access to reimbursed medicinal products in the United Kingdom, Denmark, Germany, Italy and Poland as a source of information intended to be used by government authorities in the decision-making process.
Methods: A systematic review was conducted through database search of Medline, SCOPUS, Embase and Cochrane Library, supplemented by nonsystematic review. The quality of the identified literature was critically appraised.
Results: Information necessary to develop a knowledge base was outline from 121 papers identified through database search. 0.83% of all publications were rated high in all of the assessed categories, i.e. were identified to represent high levels of consistency, coherence, strength and methodological quality.
Conclusions: In the policy decision-making process, concise recommendations based on validated data are more than needed. It is vital to rely on scientific evidence and avoid reports based on simple exchange of information or presenting single-source or unconfirmed data, including expert’s opinion.
