Providing high data rate with minimum energy consumption is a crucial challenge for next generation wireless networks. This paper focuses on wireless mesh networks using a MAC layer based on S-TDMA (Spatial Time Division Multiple Access). We investigate on the optimization issues combining throughput and energy consumption. Our contributions are two-fold. First, we formulate and solve using col...

Wireless Sensor Networks have some well known features such as low battery consumption, changing topology awareness, open environment, non reliable radio links, etc. In this paper, we investigate the benefits of Network Coding Wireless Sensor networking, especially resiliency. One of our main concern is the resiliency in Wireless Sensor Networks. We have seen that resiliency could be described ...

The current monolithic and lengthy scheme behind the standardization and the design of new video coding standards is becoming inappropriate to satisfy the dynamism and changing needs of the video coding community. Such a scheme and specification formalism do not enable designers to exploit the clear commonalities between the different codecs, neither at the level of the specification nor at the...

In this paper, we focus on broadband wireless mesh networks like 3GPP LTE-Advanced. This technology is a key enabler for next generation cellular networks which are about to increase by an order of magnitude the capacity provided to users. Such an objective needs a significative densification of cells which requires an efficient backhauling infrastructure. In many urban areas as well as under-d...

MN178 Electrical characterization of InAs-nanocrystal-based nonvolatile memories Moïra Hocevar, Philippe Regreny, Michel Gendry, Abdelkader Souifi Institut des Nanotechnologies de Lyon-INL, UMR-CNRS-5270, INSA de Lyon, 7 avenue Jean Capelle, 69621 Villeurbanne Cedex, France, [email protected] The development of highly integrated nonvolatile memory (NVM) devices has led to the use of Si...

The problem of test of fit for Vector AutoRegressive (VAR) processes with unconditionally heteroscedastic errors is studied. The volatility structure is deterministic but time-varying and allows for changes that are commonly observed in economic or financial multivariate series such as breaks or smooth transitions. Our analysis is based on the residual autocovariances and autocorrelations obtai...

Data warehouses are being used in many applications since quite a long time. Traditionally, new data in these warehouses is loaded through offline bulk updates which implies that latest data is not always available for analysis. This, however, is not acceptable in many modern applications (such as intelligent building, smart grid etc.) that require the latest data for decision making. These mod...

The application of Formal Concept Analysis (FCA) to Information Retrieval (IR) is twenty-five years old. Over this period, a number of papers have explored the potentials of FCA for various information finding tasks while several system prototypes have been made available for experimentation and testing. In this talk we survey what has been achieved so far, discussing lessons and implications f...

The main goals of this essay are to describe and make clear the philosophical implications self-cultivation concerning concept inwardness examine how it contributes formation Confucian identity. In two representative Korean Neo-Confucian debates, Debate on Supreme Polarity between Yi Ǒnjŏk Cho Hanbo one issues in Horak about original substance tranquil state (mibal) mind, we can see that plays ...
