Recently, bicycle accidents have been increasing. One of the causes is poor road maintenance because of its high costs. The purpose of this study is the reduction of maintenance cost. We propose a method to detect road damage from cyclists pedaling motion. First, cyclists wear a smartphone in their pants' side pocket and collect acceleration signals with embedded accelerometer. Second, the collected signals are separated into road signal and pedaling signal by applying Independent Component Analysis (ICA). Finally, road condition is classified depending on road signal's feature. We carried out experiments on three road conditions: flat, positive step damage, and negative step damage. Using proposed method, road condition's classification overall accuracy was 70%.

Movements synchronism is a key parameter for team sports. To determine whether human movements in rowing are synchronous or not, we developed a system that acquires signals through accelerometers and compares those signals using correlation. System components are tuned to reduce the delay between the time at which the action occurs and the one the system produces the output. We present an application to help training synchronized movements and use it to test the system with elite rowing athletes. The system generates the output within 500 ms from the moment of the movement.

In this paper, we describe the location method for Smartphone. The method uses combination of camera and orientation sensor for reduces processing cost for smartphone, because a resource of a smartphone is low and image processing needs high processing resource.

Today, it is hardly conceivable to produce new objects without digital capabilities. We can notice that the development of the ability to communicate of these new objects raises up new questions about using them or not. The UNUOC project (Usage et Non-Usage des Objets Communicants -- Use and Non-Use of communicating devices) studies the ways such objects are used, and more precisely raise the questions of their connection and disconnection.

Long-term monitoring of cultivation environments and a scientific understanding of tree vigor and grape quality are needed for advanced viticultural management. Cultivation environments, such as micrometeorological data and soil moisture, should be continuously monitored. In addition, we have to get a good grasp of grapevine vigor in association with the surrounding climate and soil water stress, in order to grow high-quality grapes. In this paper, we discuss a wireless sensor network for climate and soil moisture measurement in the vineyard. As regards tree vigor, grapevine sap flow was measured to evaluate gas exchange capacity at grapevine canopies. We also made the color image measurement of grape berries in the vineyard for high quality cultivation.

Machine-to-Machine (M2M) systems are smart networks composed of multiple devices sensing or acting in the physical world. These devices interact together to provide data to value-added services or applications developed by various stakeholders. M2M infrastructures aim at being deployed in city wide area. They have to handle and support an increasing number of services and applications. A dynamic sharing of M2M infrastructure between applications is thus a strong requirement. To answer to such a challenge, we propose to use the multi-agent paradigm and related programming languages. Adopting a multi-agent oriented programming approach, we define an adaptive and agile layer to govern M2M infrastructures supporting different applications.
