Strengthening Cross-border Law Enforcement Cooperation: the Prüm Network of Information Exchange

The Prüm network was established to provide mechanisms and the infrastructure to achieve a closer cooperation between the EU member states in combating terrorism, organised crime and illegal immigration through the cross border exchange of DNA profiles, fingerprints and vehicle registration data. While Prüm offers clear benefits for cross-border policing, it continues to present challenges of a technical and scientific nature as well as legal, ethical and socioeconomic concerns. This article reviews these challenges as well as the existing safeguards. It argues that, in order to achieve Prüm benefits and maximise its potential, it is important to enhance the necessary dialogue and cooperation between member states so as to confront the above concerns and address challenges posed by Prüm through balanced measures

Experimental and Computational Bearing Strength of Fiber Metal Laminate With and Without Film Adhesive

This research characterized the performance of a fiber metal laminate composed of carbon fiber and stainless steel without film adhesive and compared it to a similar, previously tested, fiber metal laminate including film adhesive. Removal of the adhesive layers reduced the localized thickness, simplified manufacturing, and allowed for a 20% increase in foil thickness. Quasi-static testing was conducted in double shear, single shear protruding, and single shear countersunk configurations. The results were compared to adhesive hybrid and control samples. To study the affects of bolt tension, samples at low torque in double shear were also tested. Progressive failure samples revealed how damage in the hybrid propagated and what failures resulted in key features of the stress-strain curve. A finite element model was developed and accuracy within 5% was achieved compared to experimental results. The model was then compared to progressive failure samples to validate the behavior of the model. The non-adhesive hybrid showed a up to a 10% increase in ultimate strength compared to the adhesive hybrid and as much as 41% in ultimate strength compared to the control samples. Buckling of the foils in the non-adhesive hybrid was the dominating failure mechanism in all test configurations

The algorithmic regulation of security: An infrastructural perspective

This article contributes to debates on algorithmic regulation by focusing on the domain of security. It develops an infrastructural perspective, by analyzing how algorithmic regulation is enacted through the custom‐built transatlantic data infrastructures of the EU‐U.S. Passenger Name Records and Terrorism Financing Tracking Program programs. Concerning regulation through algorithms, this approach analyzes how specific, commercial data are rendered transferable and meaningful in a security context. Concerning the regulation of algorithms, an infrastructural perspective examines how public values like privacy and accountability are built into international data infrastructures. The creation of data infrastructures affects existing modes of governance and fosters novel power relations among public and private actors. We highlight emergent modes of standard setting, thus enriching Yeung's (2018) taxonomy, and question the practical effects of operationalizing public values through infrastructural choices. Ultimately, the article offers a critical reading of algorithmic security, and how it materially, legally, and politically supports specific ways of doing security
