We define post-query strategies: these are time dependent post-query protocols that are being executed in rounds. We show how existing service discovery protocols, like Jini, Bluetooth, and SLP fit within this framework. We propose several new post-query strategies that can be used for locating a service in an ad-hoc network. These include: non-adaptive, deterministic, randomized, memoryless, i...

In this work the optimal design of sensor networks for chemical plants is addressed using stochastic optimization strategies. The problem consists in selecting the type, number and location of new sensors that provide the required quantity and quality of process information. Ad-hoc strategies based on Tabu Search, Scatter Search and Population Based Incremental Learning Algorithms are proposed....

This paper studies a new, practical but challenging problem, called Class-Incremental Unsupervised Domain Adaptation (CI-UDA), where the labeled source domain contains all classes, classes in unlabeled target increase sequentially. problem is due to two difficulties. First, and label sets are inconsistent at each time step, which makes it difficult conduct accurate alignment. Second, previous u...

PURPOSE The purpose of this study was to conduct a cost effectiveness analysis of strategies designed to improve national cervical cancer screening rates, along with a distributional cost effectiveness analysis that considers regional disparities. MATERIALS AND METHODS Cost effectiveness analysis was conducted using a Markov cohort simulation model, with quality adjusted life years as the uni...

Derived values are values calculated from base values. They can be expressed with views in relational databases, or with expressions in incremental or reactive programming. However, relational views do not provide multiplicity bounds, and incremental and reactive programming require significant boilerplate code in order to encode bidirectional derived values. Moreover, the composition of variou...

OBJECTIVE Newer medications offer more options for glycemic control in type 2 diabetes. However, they come at considerable costs. We undertook a health economic analysis to better understand the value of adding two newer medications (exenatide and sitagliptin) as second-line therapy to glycemic control strategies for patients with new-onset diabetes. RESEARCH DESIGN AND METHODS We performed a...

Testing for latent tuberculosis infection (LTBI) in HIV-infected persons in low tuberculosis (TB) incidence areas is often recommended. Using contemporary, clinical data, we report the yield and cost-effectiveness of testing all HIV attendees, two current UK strategies and no LTBI testing. Economic modelling was performed utilising 10-year follow up data from a large HIV clinical cohort. Outcom...
