The antenna placement problem, or cell planning problem, involves locating and configuring infrastructure for cellular wireless networks. Many authors have looked at computationally efficient methods to create feasible or optimised cell plans. However in most approaches the tension between conflicting objectives is generally addressed implicitly rather than(More)
OBJECTIVES To examine school-level relationships between deprivation and breakfast eating behaviours (breakfast skipping and the healthfulness of foods consumed) in 9-11-year-old schoolchildren and to examine whether attitudes towards eating breakfast mediated these relationships. DESIGN Cross-sectional survey. SETTING One hundred and eleven primary(More)
It is increasingly important to optimally select base stations in the design of cellular networks, as customers demand cheaper and better wireless services. From a set of potential site locations, a subset needs to be selected which optimizes two critical objectives: service coverage and financial cost. As this is an NP-hard optimization problem, heuristic(More)
BACKGROUND A recent HTA review concluded that there was a need for RCTs of exercise referral schemes (ERS) for people with a medical diagnosis who might benefit from exercise. Overall, there is still uncertainty as to the cost-effectiveness of ERS. Evaluation of public health interventions places challenges on conventional health economics approaches. This(More)
Cellular wireless networks transmit signals from base stations, over an area commonly referred to a as a cell, to provide local area coverage to subscribers. As the power of transmission is restricted, multiple cells are required to provide wide area coverage. When operators set up or expand a network, multiple potential sites are normally available.
