Private parties and the annulment procedure: Can the gap in the European system of judicial protection be closed?

The restrictions imposed on the possibility for an individual to challenge European law measures and the restrictive interpretation of the notion of ‘individual concern’ given by the European Court of Justice have been highly criticised by legal scholars and members of the European judiciary as being against the principle of effective judicial protection. This paper shows how the restrictive interpretation of the notion of ‘individual concern’ developed in the case law of the European Court of Justice. Furthermore, the paper discusses possible improvements to the current system of judicial protection, such as the possibility to introduce a fundamental rights complaint procedure and the obligation of Member States to provide for effective judicial remedies before national courts. Finally, the impact of the modifications made by the Lisbon Treaty to the annulment procedure is assessed

Cumulant expansion for phonon contributions to the electron spectral function

We describe an approach for calculations of phonon contributions to the electron spectral function, including both quasiparticle properties and satellites. The method is based on a cumulant expansion for the retarded one-electron Green's function and a many-pole model for the electron self-energy. The electron-phonon couplings are calculated from the Eliashberg functions, and the phonon density of states is obtained from a Lanczos representation of the phonon Green's function. Our calculations incorporate ab initio dynamical matrices and electron-phonon couplings from the density functional theory code ABINIT. Illustrative results are presented for several elemental metals and for Einstein and Debye models with a range of coupling constants. These are compared with experiment and other theoretical models. Estimates of corrections to Migdal's theorem are obtained by comparing with leading order contributions to the self-energy, and are found to be significant only for large electron-phonon couplings at low temperatures

Utilization-based dynamic scheduling algorithm for wireless mesh networks

Channel access scheduling is one of the key components in the design of multihop wireless mesh networks (WMNs). This paper addresses the allocation/demand mismatch problem observed in oblivious WMN channel access scheduling schemes and proposes Utilization-Based Scheduling (UBS). UBS is a Spatial-TDMA- (STDMA-) based dynamic channel access scheduling scheme designed with the aim of increasing the application-level throughput. In UBS, each node has a weight, which is dynamically adjusted in accordance with the node's slot usage history and packet-queue occupancy. UBS is a fully distributed algorithm, where each node adjusts its own weight and makes pseudorandom transmission attempts using only the locally available information. To demonstrate the performance improvements of the dynamic weight adjustment, the performance of UBS is compared against other channel access scheduling schemes through extensive ns-2 simulations under both uniform and nonuniform traffic patterns. © 2010 Miray Kas et al

Imperatives of Computer Base Test (CBT) on Performance of LIS Students: A Case Study

Abstract The paper espouse the fact that paper pen test (PPT) is slowly replaced by computer base test (CBT) introduced over five decades ago in most tertiary institutions. It itemized the benefits and challenges of CBT. The focus is to assess the performance of students of LIS in a Nigerian university who pioneered the project. Factoring incorporated courses, necessity for the incorporation of CBT, influence of CBT on student performance and the challenges of CBT on these students performance anchored the thrust of the paper. The study was quantitative; questionnaire was used to collect data that is guided by the objective of the study. A total of 267 students participated. The study revealed that CBT incorporation is still at pilot level and that the pencil pen test stills prevails in the study area, however, since CBT incorporation, it has put to rest the claim that drudgery was one of the reasons for its utilization. Results show that its incorporation has encouraged students to be thorough and improve their technical skills. Challenges hinges on funding of the project, training of personnel and students must be prioritized for sustainability

A Survey on Scheduling in IEEE 802.16 Mesh Mode

Cataloged from PDF version of article.IEEE 802.16 standard (also known as WiMAX) defines the wireless broadband network technology which aims to solve the so called last mile problem via providing high bandwidth Internet even to the rural areas for which the cable deployment is very costly. The standard mainly focuses on the MAC and PHY layer issues, supporting two transmission modes: PMP (Point-to-Multipoint) and mesh modes. Mesh mode is an optional mode developed as an extension to PMP mode and it has the advantage of having an improving performance as more subscribers are added to the system using multi-hop routes. In 802.16 MAC protocol, mesh mode slot allocation and reservation mechanisms are left open which makes this topic a hot research area. Hence, the focus of this survey will mostly be on the mesh mode, and the proposed scheduling algorithms and performance evaluation methods
