This paper presents the first distributional analysis of a linear probing hashing scheme with buckets of size b. The exact distribution of the cost of successful searches for a bα-full table is obtained, and moments and asymptotic results are derived. With the use of the Poisson transform distributional results are also obtained for tables of size m and n elements. A key element in the analysis...

The dataset contains information about 14 million bank card transactions made by customers of the Banco Bilbao Vizcaya Argentaria (BBVA) in the metropolitan areas of Barcelona and Madrid in 2011. For both case studies, we only consider the credit card payments whose amount was inferior to 1000 euros, and which were made inside the metropolitan areas, by bank customers that lived and worked in t...

Social scientists identify two core functions of modern welfare states as redistribution across (a) socio-economic status groups (Robin Hood) and (b) ‘the lifecycle’ (the piggy bank). But what is the relative importance these functions? The answer has been elusive, bank metaphorical. intra-personal time-travel resources it implies based on non- quid-pro-quo transfers. In practice, ‘lifecycle re...

Seven years ago, I was a contented doctor in what I considered to be an above-average practice. Our group of seven family physicians earned incomes well above the national average. I had a panel of 2,600 patients and was taking six to eight weeks of vacation per year. But our profitability came with a cost. We were passing patients through the office faster and faster, with more and more things...

BACKGROUND Health workforce distribution is so important in access posture, coverage and equity. Following millennium development goals (MDGs), special attention to health workforces in relation with maternal and child health is required. OBJECTIVE The aim of the current study was to determine distribution of maternal and child health related workforces in Iran during 2010-2012, using inequal...

BACKGROUND The health workforce has a dynamically changing nature and the regular documentation of the distribution of health professionals is a persistent policy concern. The aim of the present study was to examine available human medical resources in primary care and identify possible inequalities regarding the distribution of general practitioners in Albania between 2000 and 2004. METHODS ...

We introduce a novel numerical method, named the Robin Hood method, of solving electrostatic problems. The approach of the method is closest to the boundary element methods, although significant conceptual differences exist with respect to this class of methods. The method achieves equipotentiality of conducting surfaces by iterative non-local charge transfer. For each of the conducting surface...
