Layering the Internet-of-Things with Multicasting in Flow-sensors for Internet-of-services

Development of Internet-of-Services will be hampered by heterogeneous Internet-of-Things infrastructures, such as inconsistency in communicating with participating objects, connectivity between them, topology definition & data transfer, access via cloud computing for data storage etc. Our proposed solutions are applicable to a random topology scenario that allow establishing of multi-operational sensor networks out of single networks and/or single service networks with the participation of multiple networks; thus allowing virtual links to be created and resources to be shared. The designed layers are context-aware, application-oriented, and capable of representing physical objects to a management system, along with discovery of services. The reliability issue is addressed by deploying IETF supported IEEE 802.15.4 network model for low-rate wireless personal networks. Flow- sensor succeeded better results in comparison to the typical - sensor from reachability, throughput, energy consumption and diversity gain viewpoint and through allowing the multicast groups into maximum number, performances can be improved.

Intersections on moduli spaces of curves

We present a new approach to perform calculations with the certain standard classes in cohomology of the moduli spaces of curves. It is based on an important lemma of Ionel relating the intersection theoriy of the moduli space of curves and that of the space of admissible coverings. As particular results, we obtain expressions of Hurwitz numbers in terms of the intersections in the tautological ring, expressions of the simplest intersection numbers in terms of Hurwitz numbers, an algorithm of calculation of certain correlators which are the subject of the Witten conjecture, an improved algorithm for intersections related to the Boussinesq hierarchy, expressions for the Hodge integrals over two-pointed ramification cycles, cut-and-join type equations for a large class of intersection numbers, etc.

Social Impact of Coca Crops in Colombia. : From socio-territorial processes to new social configurations: the role of land tenure, armed conflict, environment and coca crops.

This paper explores alterations in social dynamics caused by coca crops in Curvaradó and Jiguamiandó, at Choco department in the Colombian Pacific region. The research analyzes the role of armed actors such as paramilitaries and guerrillas in the conformation of new social spaces where local people find resistance as the main tool to survive in chaotic environments. Local power as a politics of resistance is also analyzed. Non-governmental organizations are a key tool to comprehend new social configurations. By doing the analysis and comparison using political ecology as the theoretical background along with concepts of moral economy and everyday resistance, with qualitative research methods. The paper aims to interpret and provide a better understanding of those changes considering social-environmental relations. Findings suggest that those changes in social structure are leading to an understanding, not just of the organization of the area, but also that social dynamics and coca crops cannot be generalized in the country.
