A vehicular ad hoc network (VANET) uses vehicles as mobile nodes in a Mobile ad hoc Network (MANET) to create a mobile network. Vehicles on the road usually move in one direction or in one pattern which we can use for creating network on the road. Every vehicle which is moving on the road can act as router and used to create network and with the help of this network packets can be disseminated ...

Data streams are usually characterized by changes in the underlying distribution generating data. Therefore algorithms designed to work with data streams should be able to detect changes and quickly adapt the decision model. Rules are one of the most interpretable and flexible models for data mining prediction tasks. In this paper we present the Adaptive Very Fast Decision Rules (AVFDR), an on-...

For real-time communication services to achieve widespread usage, it is important that the network services behave gracefully if any component(s) fail. While other researchers have previously considered failure-handling for non-real-time communication as well as for unicast real-time communication, these failure-recovery techniques must be reexamined in the light of the changes introduced by th...

ÐIn many real-time control applications, the task periods are typically fixed and worst-case execution times are used in schedulability analysis. With the advancement of robotics, flexible visual sensing using cameras has become a popular alternative to the use of embedded sensors. Unfortunately, the execution time of visual tracking varies greatly. In such environments, control tasks have a no...

layer between the scheduler and concrete operations on objects. This abstract layer can guarantee the system safety requirements, e.g. prevent the building of a system in which blanks and devices can collide, and therefore ease and simplify the task of designing and implementing a scheduler that controls the dynamic execution of CA actions. The proposed structuring framework used in this indust...

The main objective of this paper is to present a method for handling non-preventable and non-avoidable catastrophic exceptions in embedded hard real-time environments in a well-structured and predictable way, and as painlessly as possible. First, apt hardware and software platforms which are prerequisite for predictable system behaviour are brieey presented. Then, some existing techniques are s...

Prior studies at Purdue University have shown that PTO entanglements occur most frequently on portable grain augers. A research project was conducted to measure operator exposure to PTO components and document work patterns during the use of grain augers. Information on the methodologies used to measure operator exposure is presented along with data on exposure to conventional grain augers whil...

Nowadays, critical and complex systems are widely used in our daily life. Modern technology provides great rapid changes in manufacturing these systems, and so continuous increasing in the complexity of their diagnostic systems. However, many intelligent systems and techniques have been developed in this manner. But, till now there is a great complexity appeared to have good performance for dia...

A number of approaches exists that permit to synthesize the operational state-based behavior of a set of components for a set of scenarios. In this paper we explore how to extend these approaches to also tackle the problem for scenarios with parametric timing constraints in form of upper and lower time bounds. The resulting time consistency problems are identified and ideas for an algorithmic h...

The functional response is a key element of predator-prey interactions, and variations in its parameters influence interaction strength and population dynamics. Recent studies have used the equation of the metabolic theory of ecology (MTE) to quantify the effect of temperature on the parameter Th, called "handling time," and then predict the responses of predators and communities to climate cha...
