Sensitivity to Gravitational Waves from Compact Binary Coalescences Achieved during LIGO's Fifth and Virgo's First Science Run

We summarize the sensitivity achieved by the LIGO and Virgo gravitational wave detectors for compact binary coalescence (CBC) searches during LIGO's fifth science run and Virgo's first science run. We present noise spectral density curves for each of the four detectors that operated during these science runs which are representative of the typical performance achieved by the detectors for CBC sear

Lunds universitet vill prioritera humaniora och samhällsvetenskap

Fyra professorer från Lunds universitet: Lunds universitet framhåller humaniora och samhällsvetenskaper i sina prioriteringar inför höstens forsknings- och innovationsproposition. Skulle regeringen plocka upp den kastade handsken kan det innebära ett trendbrott inom forskningspolitiken.

The European Union readmission policy after Lisbon

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

Closed-form calibration of the Gantry-Tau parallel robot

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

Extreme Hardness Achievements in Binderless Cubic Boron Nitride Tools

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

Optimal intra-symbol transmit windowing for multicarrier modulation

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
