Brexit will deepen the fault lines within the EU over mobility. CEPS Commentary, 12 July 2016

Much has been made of the divide that opened up in 2015 between eastern and western member states as a result of acrimonious discussions on how to handle the refugee crisis and distribute asylum applicants across the EU. Against the prevailing political sentiment in certain member state capitals, Germany and France pushed through a plan devised by the European Commission to relocate 120,000 refugees, by a qualified majority vote in the Council. Rather than creating an east/west divide, however, the vote split the group of (relatively) new Central and Eastern European countries (CEECs) of the EU into two factions: Romania, Czechia, Slovakia and Hungary voted against the plan, whereas several other CEECs, namely Poland, Bulgaria and the Baltic states, joined the controversial motion on the side of the other (northern, southern and western) member states. Finland abstained. Few member states have shifted their positions in the meantime. If anything, in fact, they have coalesced among the Visegrad 4, following a change of government in Poland; and they have hardened, as a result of new proposals by the Commission to fine member states that refuse to accept refugees. With Hungary’s referendum on the Commission’s relocation scheme scheduled for October 2nd, tensions are set to intensify even further.

Fault diagnosis of an automotive suspension system

With the development of the embedded application and driving assistance systems, it becomes relevant to develop parallel mechanisms in order to check and to diagnose these new systems. In this thesis we focus our research on one of this type of parallel mechanisms and analytical redundancy for fault diagnosis of an automotive suspension system. We have considered a quarter model car passive suspension model and used a parameter estimation, ARX model, method to detect the fault happening in the damper and spring of system. Moreover, afterward we have deployed a neural network classifier to isolate the faults and identifies where the fault is happening. Then in this regard, the safety measurements and redundancies can take into the effect to prevent failure in the system. It is shown that The ARX estimator could quickly detect the fault online using the vertical acceleration and displacement sensor data which are common sensors in nowadays vehicles. Hence, the clear divergence is the ARX response make it easy to deploy a threshold to give alarm to the intelligent system of vehicle and the neural classifier can quickly show the place of fault occurrence.

Propagation of Behavioral Variations with Delegation Proxies

Scoping behavioral variations to dynamic extents is useful to support non-functional concerns that otherwise result in cross-cutting code. Unfortunately, such forms of scoping are difficult to obtain with traditional reflection or aspects. We propose delegation proxies, a dynamic proxy model that supports behavioral intercession through the interception of various interpretation operations. Delegation proxies permit different behavioral variations to be easily composed together. We show how delegation proxies enable behavioral variations that can propagate to dynamic extents. We demonstrate our approach with examples of behavioral variations scoped to dynamic extents that help simplify code related to safety, reliability, and monitoring.
