Classification is considered to be one of the important building blocks in data mining problem. The major issues concerning data mining in large databases are efficiency and scalability. This paper addresses these issues by proposing a data classification method using AVL trees, which enhances the quality and stability. Researchers from various disciplines such as statistics, machine learning, ...

The emphasis of this research effort was on using AVL and APC dynamic data to develop a bus travel time model capable of providing real-time information on bus arrival and departure times to passengers (via traveler information services) and to transit controllers for the application of proactive control strategies. The developed model is comprised of two Kalman filter algorithms for the predic...

With increasing data availability due to intelligent transportation systems (ITS) deployments, methods for assessing and reporting traffic characteristics and conditions have begun to shift. While previous level of service (LOS) methods were developed for use with limited data, we now have the power to develop and test the use of actual performance measures. Important measures like average spee...

Abstract In Brazil, American visceral leishmaniasis (AVL) has become a public health concern due to its high incidence and lethality. This study aimed analyze the clinical, epidemiological, laboratory aspects of AVL in state Brazil. descriptive, cross-sectional, retrospective, quantitative notified cases was carried out Alagoas between 2008 2017 from data obtained DATASUS/SINAN. Sociodemographi...

A common problem of large scale search engines and web spiders is how to handle a huge number of encountered URLs. Traditional search engines and web spiders use hard disk to store URLs without any compression. This results in slow performance and more space requirement. This paper describes a simple URL compression algorithm allowing efficient compression and decompression. The compression alg...

—Generally vehicular networks are considered to contain two types of nodes; vehicles and roadside stations. Vehicular communications is usually developed as a part of Intelligent Transport Systems (ITS) that seeks to achieve safety and productivity through intelligent transportation which integrates communication between mobile and fixed nodes. The majority of today's automated vehicle location...

We present an approach for inferring symbolic resource bounds for purely functional programs consisting of recursive functions, algebraic data types and nonlinear arithmetic operations. In our approach, the developer specifies the desired shape of the bound as a program expression containing numerical holes which we refer to as templates. For e.g, time ≤ a ∗ height(tree) + b where a, b are unkn...

To investigate the diagnostic value of electrocardiographic (ECG) ST-segment in acute inferior myocardial infarction (AIMI) caused by the left circumflex branch (LCX).A total of 240 clinical cases with AIMI in our hospital were retrospectively analyzed. All of them had received percutaneous coronary intervention (PCI) within 12 hours after symptom onset. The clinical features, ECG manifestation...

In this paper we combine Hardware Transactional Memory (HTM) with Read-Copy-Update (RCU) to implement highly scalable concurrent balanced Binary Search Trees (BSTs). The two key features of our approach are: a) read-only operations require no synchronization or restarts and b) tree modifications are first performed in private copies of subtrees, then HTM is used to validate their consistency, a...
