Formalism vs. empiricism. Some reflections on the Dublin convention on the occasion of recent European case law

The drafters of the 1990 Dublin Convention knowingly and willfully disregarded divergences among Member States' protection systems. Like a boomerang, the fallacy of this approach has now reappeared in cases where asylum seekers have challenged transfers under the Convention, tasking judges to tackle a problem which its drafters avoided. The core issue of this article is whether and when such diver

Hardware Implementation of the Exponential Function Using Taylor Series

This paper presents hardware implementations of Taylor series. The focus will be on the exponential function but the methodology is applicable on any unary function. Two different architectures are investigated, one, original, straight forward and one modified structure. The outcomes are higher performance, lower area, and lower power consumption for the modified architecture compared to the origi

Control Signal Constraints and Filter Order Selection for PI and PID Controllers

Large control signal derivatives or inter-sample differences may harm actuators. An optimization constraint limiting such variations, related to measurement noise, is derived. Using the constraint, optimal PI, PID and measurement filters with different orders are designed for several processes and compared to the optimal linear controller of high order found via Youla parametrization. Simulations

Mahalla in Post-Soviet Uzbekistan

This article examines the validity of international reports and policy analyses on Uzbekistan, and possibly on other Central Asian countries, regarding informal economic practices as a social evil that undermines the legitimacy and efficiency of public policies. The research presented is based on three periods of fieldwork between 2009 and 2012 in rural Fergana, Uzbekistan, and uses the case of ma

Sum rules and constraints on passive systems

A passive system is one that cannot produce energy, a property that naturally poses constraints on the system. A system on convolution form is fully described by its transfer function, and the class of Herglotz functions, holomorphic functions mapping the open upper half plane to the closed upper half plane, is closely related to the transfer functions of passive systems. Following a well-known re
