The embedded systems market and especially the software part of it is growing drastically in automotive industry. Today we see that the value of software or functionality that is realized using software within cars is about 35% of the value of the car itself. We have typically more than 70 embedded control units (ECUs) in a car with functionality realized and controlled by software. The standardization of communication interfaces and operating system functionality as for example realized by AUTOSAR facilitates the distributed development of software. But the needs to produce software in time and in budget remain still a main task in automotive software industry. To cope with tight project plans, process models based on product line technology promise a good chance to be successful. Nevertheless, the need to control the product development remains still one of the most important questions in this area. The work presented here gives some new insights into the definition and application of measures with special emphasis on the variability aspects used within a product line development. Several known techniques as for example atomic sets or formal variability analysis are revisited and used within the context of variability metrics. The measures are categorized and can be used within a project to control and manage the defined variability. Copyright 2011 ACM.

In this paper we present a novel algorithm, implemented in a wireless sensor network environment, for the study of fire in a natural environment. This algorithm can offer two kinds of information: the risk of a fire and, in case of an active fire, the propagation direction of the flames and their velocity. This information is useful for fire rangers in order to obtain escape ways and determine strategies for putting off the fire. The evaluation of the proposal algorithm is performed using an ad-hoc simulator. The preliminary results obtained show that the proposed algorithm is a promising method that can be used to solve the most common problems related to fire control and detection.
