This article conducts a brief historical excursus on the evolution of the EU’s readmission policy through the analysis of readmission agreements, meant as its main legal instruments. The Lisbon Treaty is herein portrayed as an historical watershed in the recognition of both an express competence of the Union with regard to measures aimed to address the readmission of irregular migrants, and a new
This paper addresses the kinematic calibration of the Gantry-Tau parallel kinematic manipulator. It offers two closed-form solutions to this problem, which do not need any initial guess, contrarily to most calibration methods that are based on non-linear least square minimization. This makes the proposed methods applicable by non expert users in a context of mechanical modularity of the robot. Exp
Binderless cubic boron nitride tools are available in two forms: single phase cBN and dual phase wBN/cBN (w is wurtzite phase). In this work, a novel heat treatment process involving surface heating using a continuous wave CO2 laser followed by tandem waterjet quenching of the laser beam path was applied to increase the hardness of both forms of boron nitride. Stress-induced phase transitions and
Windowing of the transmitted blocks in a multicarrier system yields an improved spectral containment of the resulting basis functions, which allows larger transmit power compared to no windowing while fulfilling the power spectral density (PSD) requirements. Most transmit window designs proposed so far aim at maximising the mainlobe energy and thus the spectral containment of the transmit basis fu

Popular Abstract in Swedish Denna avhandling behandlar ämnet känselåterkoppling i handproteser. Att mista sin hand är en traumatisk upplevelse och den som har mist sin hand förlorar både känsel och motorik. En rudimentär greppfunktion kan återskapas genom att använda en handprotes. Nya och avancerade proteser som kontrolleras med hjälp av muskelsignaler finns numera på marknaden och dessa myoelektAmputation of the hand implies the loss of the ability to grasp and the ability to "feel". The grasping function can be primitively restored using an active prosthesis. Multiarticulating electrically powered hands have recently made their way to the market and these hands provide enhanced grasping and gripping capabilities. However, these hands provide no direct and conscious sensory feedback to
