This ebook constitutes the refereed complaints of the 5th foreign Symposium on Spatial Databases, SSD '97, held in Berlin, Germany, in July 1997.
The 18 revised complete papers awarded have been rigorously chosen from a complete of fifty five submissions. additionally integrated are keynote contributions. The papers are geared up in topical sections on spatial similarities, geo-algorithms, spatial constraint databases, spatial question processing, platforms, spatial information types and spatial entry methods.

This publication constitutes the refereed complaints of the seventh foreign convention on textual content, Speech and discussion, TSD 2004, held in Brno, Czech Republic, in September 2004. The seventy eight revised complete papers provided including three invited papers have been rigorously reviewed and chosen from 128 submissions. The papers current a wealth of cutting-edge examine leads to the sphere of traditional language processing with an emphasis on textual content, speech, and spoken discussion starting from theoretical and methodological matters to purposes in a variety of fields, resembling info retrieval, the semantic internet, algorithmic studying, class and clustering, speaker reputation and verification, and discussion administration.
This publication constitutes the completely refereed post-proceedings of the 4th overseas info Hiding Workshop, IHW 2001, held in Pittsburgh, PA, united states, in April 2001. The 29 revised complete papers provided have been rigorously chosen in the course of rounds of reviewing and revision. All present concerns in info hiding are addressed together with watermarking and fingerprinting of digitial audio, nonetheless picture and video; nameless communications; steganography and subliminal channels; covert channels; and database inference channels.
This day, PKIs have come of age they usually aid the protection of numerous huge networked structures, resembling company-wide rfile administration systems,- governmentapplicationsandsecureVPN. However,despitethissuccess,the? eld has no longer but reachedits complete scienti? c adulthood and there's nonetheless room for study during this sector.

Vitabile et al. The proposed intelligent sensor is composed by a Sensor Acquisition Module (SAM) and a Sensor Processing Module (SPM). The ﬁrst one is based on Hamster Secugen sensor  for ﬁngerprint image acquisition. The second one is an FPGA based prototype implementing the whole ﬁngerprint recognition chain. Modules have been installed on a standard workstation and their communication exploits standard PCI bus. R. R (False Rejection Rate) have been used to verify its performance. R. R. of 8%.
7×) over the same baseline SIMD array. z CAX reduces energy consumption from 80% to 89%, but MDMX reduces energy consumption from only 60% to 79% over the baseline version. z Moreover, CAX benefits from reduced pixel word storage in addition to greater concurrency. As a result, CAX outperforms MDMX for all the programs in area efficiency and energy efficiency. The area efficiency increases from 36% to 68% (an average of 52%) with CAX, but only 6% to 22% (an average of 13%) with MDMX. The energy efficiency increases from 35% to 77% (an average of 50%) with CAX, but only 2% to 24% (an average of 11%) with MDMX.
Experimental trials conducted on our sensor images show that they range around ﬁxed values: 100, 250, 38, 5190, respectively. Fixing the above values, the equations to calculate the normalized pixel becomes more simple without the use of the square root and division operators: G(i, j) = M0 + (I(i, j) − M ) << 2 if I(i, j) ≥ M (2) G(i, j) = M0 − (I(i, j) − M ) << 2 if I(i, j) < M (3) where I(i,j) is the intensity of the pixel at the ith row and jth column and G(i,j) the relative normalized value.
