Online advertising has seen great growth over the past few years. Advertisers have gotten better results with campaigns targeted at more specific audiences. Ad networks with few visits are unable to create such campaigns and hence are moving forward towards a new model, consisting of a huge global ad exchange market. In this market millions of advertisers compete for the ad space so that their ...

With the rapid development of urbanization, metro becomes more and important for people’s travel in big cities. To quantitatively describe passenger flows on congested transfer routes, this paper introduces a dynamic model based automated data from automatic fare collection (AFC) vehicle location (AVL) systems. An expectation maximization (EM) algorithm is proposed to compute maximum likelihood...

In this study, three raw Brazilian clays from Joao Pessoa, Paraiba State (Aco AP, AVL and Verde Lodo) were characterized before after purification acid activation. Several instrumental techniques used, the classified as dioctahedral smectites with different compositions, where sample had highest content of montmorillonite. addition, analyses showed modification in clay mineral mainly due to rem...

The Academic Vocabulary List (AVL) (Gardner & Davies, 2014) is a valuable resource for EAP teachers and students as it identifies potential lexical learning/teaching targets. This study enhances the AVL's pedagogical usefulness by identifying polysemous lemmas in it. Polysemous AVL are operationalised those with more than one definition two lexicographic resources, Collins COBUILD Advanced Lear...

This paper presents research on the combustion and emission characteristics of a four-stroke Natural gas–Diesel dual-fuel marine engine at full load. The AVL FIRE R2018a (AVL List GmbH, Graz, Austria) simulation software was used to conduct three-dimensional simulations process formations inside cylinder in both diesel mode analyze in-cylinder pressure, temperature, characteristics. results wer...

This study investigates the impact of pharmacy policies on patient waiting time in the Chemotherapy Day Unit of the Netherland Cancer Institute Antoni van Leeuwenhoek hospital (NKI-AVL). The project evaluated whether a reduction in waiting time resulting from medication orders being prepared in advance of patient appointments was justified, given that medications prepared in advance risked bein...

K-Dimensional Height Balanced Trees represent one solution to handle simultaneous tree operations (insertion, search) with multiple value keys in an efficient way. The current paper focuses on discussing some of the intricacies and overhead caused by the concurrency aspects, as well as providing an implementation of the algorithm, together with a discussion regarding its correctness. 1. Context...
