For a number of years vehicle fleet tracking systems are in use in companies operating large number of vehicles in the field. Proliferation of cheap and compact GPS receivers had the effect that Automatic Vehicle Location (AVL) systems today almost exclusively use satellite based locating systems. This paper presents characteristics of realized system tracking and analyzing city bus transit tra...

BACKGROUND American visceral leishmaniasis (AVL) is an emerging disease in the state of São Paulo, Brazil. Its geographical expansion and the increase in the number of human cases has been linked to dispersion of Lutzomyia longipalpis into urban areas. To produce more accurate risk maps we investigated the geographic distribution and routes of expansion of the disease as well as chemotype popul...

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...

In this paper we present a general prescription for the prediction of transit vehicle arrival/departure. The prescription identifies the set of activities that are necessary to preform the prediction task, and describes each activity in a component based framework. We identify the three components, a Tracker, a Filter, and a Predictor, necessary to use automatic vehicle location (AVL) data to p...

A study of the phlebotomine sand fly fauna was carried out in an endemic area of American visceral leishmaniasis (AVL) in the municipality of Porteirinha, in the Brazilian state of Minas Gerais. Captures were performed with CDC light traps in 7 districts, 5 days per month, during 2 consecutive years (January 2000 to December 2001). A total of 3240 sand flies were captured and identified. Sixtee...

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...

In this paper, we propose a leakage reduction technique. Because high leakage currents in deep submicron regimes are becoming a major contributor to total power dissipation of CMOS circuits. Sub threshold leakage current plays a very important role in power dissipation. So to reduce the sub threshold leakage current we proposed an adaptive voltage level (AVL) technique. Which optimize the overa...

AVL Powertrain Engineering, Inc. (AVL) is an independent company specializing in the development of powertrain systems, simulation methods, and engine instrumentation and test systems. The vehicle simulation software Cruise, developed by AVL, is commonly used by automotive original equipment manufacturers to aid in powertrain development (Mayer, 2008). Cruise simulates vehicle-driving performan...
