Nearest neighbor problem has special considerations among database researchers. In many cases of querying, users want to see returned results that contain database objects similar to a given query object, and especially these returned results are ranked according to their similarity to the query object. In this paper, we introduce two adapted algorithms to(More)
Histone proteins are subject to various posttranslational modifications (PTMs). Elucidating their functional relationships is crucial toward understanding many biological processes. Bayesian network (BN)-based approaches have shown the advantage of revealing causal relationships, rather than simple cooccurrences, of PTMs. Previous works employing BNs to(More)
According to [1], cloud computing is one of ICT core areas in the next five years. The computing paradigm also is a research trend that has attracted strongly scientist community. Until now, there are many studies, which have focused on saving energy for servers in cloud systems. During the operation process of cloud data center, idle servers bring about(More)
Cloud computing took a step forward in the efficient use of hardware through virtualization technology. And as a result, cloud brings evident benefits for both users and providers. While users can acquire computational resources on-demand elastically, cloud vendors can also utilize maximally the investment costs for data centers infrastructure. In the(More)
In comparison with other scaling techniques, forecast of workload and resource consumption brings a great advantage to SaaS operations in cloud environment because system knows early and precisely the number of resources must be increased or decreased. However, the prediction accuracy still needs to be improved further even though there are many research(More)
This paper presents our research on automatic question classification for Vietnamese using machine learning approaches. We have experimented with several machine learning algorithms utilizing two kinds of feature groups: bag-of-words and keywords. Our research focuses on two most important tasks which are corpus building and features extraction by crawling(More)
PURPOSE This paper aims to analyze the household financial burden and poverty impacts of cancer treatment in Vietnam. METHODS Under the "ASEAN CosTs in ONcology" study design, three major specialized cancer hospitals were employed to assemble the Vietnamese data. Factors of socioeconomic, direct, and indirect costs of healthcare were collected(More)
This paper describes engineering support for explicit binding and stream interfaces developed as part of the ACTS ReTINA project. It describes an abstract binding protocol that supports very exible bindings, and subsumes related proposals such as the SOR binding protocol , the Spring notion of subcontract, or the notion of virtual connection from the IMA(More)
Original approval signatures are on file with the Graduate School and the University of Oregon Libraries. Neurogenesis in Drosophila and mammals requires the precise integration of spatial and temporal cues. In Drosophila, embryonic neural progenitors, called neuroblasts, sequentially express the transcription factors Hunchback, Kruppel, Pdml/Pdm2 (Pdm) and(More)
