The idea of relaxed balance is to uncouple the rebalancing in search trees from the updating in order to speed up request processing in main-memory databases. In this paper, we describe a relaxed version of AVL trees. We prove that each update gives rise to at most a logarithmic number of rebalancing operations and that the number of rebalancing operations in the semidynamic case is amortized c...

The tire pyrolysis oil is a waste-derived fuel with lower cetane number and higher den-sity than diesel fuel, but this promising waste-based for compression ignition en-gines. In the European Union, it necessary to increase bio-share of fuels, second-generation blend components are essential achieving 2030 goals. injection characteristics were investigated on Bosch solenoid type common rail (CR...

In past work we described a system of components that are used to construct transit traveler information applications. In this paper we describe an ongoing project that uses the same component architecture to combine maps, schedules, and AVL information from four transit agencies. The result is a set of web applications suitable for both transit management and traveler information. We describe ...

In this paper, we present the vision-based absolute navigation (VIBAN) system that enables the global localization ability (also called ”pinpoint landing”) of the lander. The system integrates the absolute visual localisation (AVL) approach Landstel with visual odometry (VO), a relative visual motion estimation approach. The combination of the two vision-based sensors has several advantages. Fi...

Automatic vehicle location (AVL) and automatic passenger counting (APC) systems can generate a huge quantity and variety of operational, spatial, and temporal data. This potentially allows the discovery of new ways to enhance service quality and transport efficiency by utilizing AVL-APC inputs. There is currently no framework for implementing full service quality improvement cycles from automat...

Lutzomyia longipalpis is the most important vector of AmericanVisceral Leishmaniasis (AVL) due to Leishmania chagasi in the New World. Despite its importance, AVL, a disease primarily of rural areas, has increased its prevalence and became urbanized in some large cities in Brazil and other countries in Latin America. Although the disease is treatable, other control measures include elimination ...

In this study, heat and flow in a four cylinder direct injection diesel engine combustion chamber has been simulated by using AVL Fire ESE Diesel. order to clarify the effect of geometry on area prop-erties, bowl geometric shape two different pistons, one as standard, was taken into account analysis. Standard modified geometries have compared. The simulation results showed that shapes chambers ...
