Obtaining a good similarity matrix is extremely important in subspace clustering. Current state-of-the-art methods learn the through self-expressive strategy. However, these directly adopt original samples as set of basis to represent itself linearly. It difficult accurately describe linear relation between real-world applications, and thus hard find an ideal matrix. To better samples, we prese...

We summarize some recent results showing how the lambdacalculus may be obtained by considering the metric completion (with respect to a suitable notion of distance) of a space of affine lambda-terms, i.e., lambda-terms in which abstractions bind variables appearing at most once. This formalizes the intuitive idea that multiplicative additive linear logic is “dense” in full linear logic (in fact...

During the last ten years the number of the in vivo! ex vivo techniques in haemorheology have considerably increased and in spite of a consensus meeting held in 1986 (International Committee for Standardization in Haemorheology, ICSH,1986) little improvment can be noticed at the present time. It appears that the number of proposed tests remains high, as many of them are obsolcle and/or no longe...

This paper presents an improved linearity variable-gain amplifier (VGA) in 0.18-µm CMOS technology. The lineari­ty improvement is resulted from employing a new combinational technique, which utilizes third-order-intermodulation (IM3) cancellation mechanism using second-order-intermodul­ation (­IM2) injection, and intermodulation distortion (IMD) sinking techniques. The proposed VGA gain cell co...

Robust Header Compression (ROHC) has recently been proposed to reduce the large protocol header overhead when transmitting voice and other continous media over RTP/ UDP/IP in wireless networks. In this paper we evaluate the transmission of Global System Mobile telecommunications (GSM) encoded voice with ROHC over a wireless link. We evaluate the bandwidth savings and the voice qualities using a...

The Web 2.0 and the inexpensive cost of storage have pushed towards an exponential growth in the volume of collected and produced data. However, the integration of distributed and heterogeneous data sources has become the bottleneck for many applications, and it therefore still largely relies on manual tasks. One of this task, named matching or alignment, is the discovery of correspondences, i....

Information Systems handle big amount of data within enterprises by offering the possibility to collect, treat, keep and make information avail- able. To realize these tasks, it is important secure from intrusions that can affect confidentiality, availability integrity information. Un- fortunately, with time, technologies are more used various types attacks act on create intrusion or misuses Sy...
