Purpose The ideal-typical entrepreneur presents him/herself in the neoliberal iconography as an autonomous and pro-active individual who is highly engaged with his/her vocation. Nevertheless, empirical research on actual work engagement of self-employed scarce. In addition, phenomena like “necessity self-employment” “economically dependent raise concerns about potential eudaimonic well-being ou...

We determine necessary conditions on the structure of symbol error rate (SER) optimal quantizers for limited feedback beamforming in wireless networks with one transmitter-receiver pair and R parallel amplify-and-forward relays. We call a quantizer codebook “small” if its cardinality is less than R, and “large” otherwise. A “d-codebook” depends on the power constraints and can be optimized acco...

Practitioners have long noticed that quasi-Monte Carlo methods work very well on functions that are nearly superpositions of low dimensional functions. The reason is that the low dimensional coordinate projections of QMC rules can have very good equidistribution properties at sample sizes for which the original rule itself cannot have good equidistribution. This paper explores a converse propos...

In today’s world renewable energy is highly demanding because of increasing oil and fuelprices, desire and necessity to avert irreversible climate damage and also the unreliability of the non -renewablesources. In renewable energy, water is an important source. Previously water is used only for survivalof human being as much as food but no attentionhas been givenen to economical use and conserv...
