Sleepmode techniques for small cells provide an effective means to mitigate excessive energy consumption and interference associated with ultra-dense small cell deployments. Nevertheless, such techniques can impact network performance in traditional deployments. In this paper, we show that in the particular case of macro-controlled small cells, such as in the Phantom Cell Concept (PCC) architec...

Recent research results show that conventional hardware-only cache solutions result in unsatisfactory cache utilization for both regular and irregular applications. To overcome this problem, a number of architectures introduce instruction hints to assist cache replacement. For example, Intel Itanium architecture augments memory accessing instructions with cache hints to distinguish data that wi...

BACKGROUND Our objective was to assess the impact of obstetric mode of delivery, and in particular birth by Caesarean section (CS), on school performance in adolescents using a large, population-based cohort. METHODS We extracted data from the Swedish Medical Birth Register and National School Register. We included all live singleton births in Sweden from 1982-1995 (n = 1,489,925). School gra...

BACKGROUND Considerable barriers still prevent paediatricians from successfully using information retrieval technology. OBJECTIVES To verify whether the assistance of biomedical librarians significantly improves the outcomes of searches performed by paediatricians in biomedical databases using real-life clinical scenarios. METHODS In a controlled trial at a paediatric teaching hospital, nin...

Small business support is an important element of industrial development policy in both Northern Ireland and the Republic of Ireland. This paper examines the effect of grant support on small business performance from 1991-95. Around 50 per cent of small businesses in Northern Ireland and 30 per cent of small businesses in the Republic of Ireland received support over this period. In Northern Ir...

This paper presents a CAD-based intelligent robot workcell that consists of a neural-network-based 3D force/torque sensor, image system, a six-axis industrial robot, CAD package, and database. The capability of the CAD package is extended to provide more useful infomation, such as images, robot path coordinates, etc. A neural-network-based 3D force/torque sensor is developed for solving the unc...

We present a design methodology for a modular network processor architecture that leads to a balanced, service-defined mix between programmable processor cores, configurable hardware assists, and specialized coprocessors. Whereas the processor cores address the flexibility and extendibility needs of the networking market, the hardware components offload the processors, or even allow them to be ...

We report an unprecedented formation of mesoporous titania via a surfactant-assisted aggregating assembly of TiO(2) nanoparticles. These mesostructures possess a highly crystalline anatase phase, large and accessible pore surface area, and exhibit superior photocatalytic performance.
