Off-Line/On-Line Signatures: Theoretical Aspects and Experimental Results [chapter]

Dario Catalano, Mario Di Raimondo, Dario Fiore, Rosario Gennaro
2008 Lecture Notes in Computer Science  
Off-line/On-line digital signatures were introduced by Even, Goldreich and Micali in [12]. In these signatures the signing process is divided in two parts.  ...  The Shamir-Tauman idea is to construct off-line/on-line signatures as follows. The signer's public key is VK, like before, and pk.  ...  This paper presents some theoretical and experimental results about off-line/on-line digital signatures.  ...

Off-Line Signature Verification using Novel Feature Extraction Techniques and Trajectory Recovery

Vu Minh Nguyen, University, My, Michael Blumenstein
2018
In this process, only the information that helps to identify the authenticity of questioned signatures is extracted and retained.  ...  In total, three novel local features and four global features were proposed and investigated.  ...  It is thus necessary to distinguish between three modes of operation for an automatic signature verification system: off-line, on-line, and hybrid.  ...

Rotor Fault Detection in Line-fed Induction Machines Using Complex Wavelet Analysis of Startup Transients [chapter]

Fernando Briz, Michael W., Pablo Garcia, David Diaz-Reigosa, Alberto Diez
2010 Fault Detection  
The experimental results shown in Fig. 10 and 13 used a wide range of values for a and b to better show the results of the method.  ...  On-line methods do not stop the normal operation of the machine, while off-line methods require discontinuing the normal operation of the machine and often require moving it to a test rig.  If they can  ...

Authenticating Computation on Groups: New Homomorphic Primitives and Applications [chapter]

Dario Catalano, Antonio Marcedone, Orazio Puglisi
2014 Lecture Notes in Computer Science  
As a second result, we show how to construct linearly homomorphic signature schemes to sign elements in bilinear groups (LHSG for short).  ...  Next we give evidence that RMA secure LHSG are interesting on their own right by showing applications in the context of on-line/off-line homomorphic and network coding signatures.  ...  Dario Catalano, Mario Di Raimondo, Dario Fiore, and Rosario Gennaro.

Huseyin M. Ertunc, Kenneth A. Loparo, Hasan Ocak
2001 International journal of machine tools & manufacture  
Experimental results demonstrate the effectiveness of the proposed methods.  ...  Kanai and Kanda [16] classified the various types of drill wear for large drills (of diameter Ն6 mm); these are illustrated in Fig. 2 in addition to chipping at the cutting lips (P T and P M ).  ...  Acknowledgements The authors would like to thank John Gorse and Karl Ziegler from Eaton MTC for providing technical support and access to their laboratoy for the experimental part of our work.  ...

A Conditional Random Field Framework for Robust and Scalable Audio-to-Score Matching

Cyril Joder, Slim Essid, Gaël Richard
2011 IEEE Transactions on Audio, Speech, and Language Processing  
Three types of features are used, characterizing the local harmony, note attacks and tempo.  ...  Experiments run on a large database of classical piano and popular music exhibit very accurate alignments.  ...  Depending on the targeted application, the alignment can be either on-line or off-line.  ...

(i) First, the automatic identification of the operational phases described above (OFF-line, ON-line transient and ON-line steady) is automatically performed.  ...  Section 5.6 provides a theoretical and an analytical comparison between TCharM and four previous studies on clustering Twitter data. Section 5.7 discusses in depth the experimental results.  ...  Hence, the spatial distance ( , ) between tweets and is computed as where ℎ = sin 2 (Δ /2) + cos 1 ⋅ cos 2 ⋅ sin 2 (Δ /2) and Δ and Δ are latitudinal and longitudinal differences between the tweets and  ...

Infant attention to phonetic detail in word forms : knowledge and familiarity effects

Christopher Terrence Fennell
2004
These results are compatible with the limited resource explanation and discount the representational discontinuity argument by demonstrating that the relevant contrast is already present in words.  ...  Because infants can discriminate the same phonetic detail that they fail to use in word-learning situations, the argument is that this word-learning failure results from a processing overload on cognitive  ...  On-line scores were rounded to the nearest 0.1 s. Off-line scoring was also done to the nearest 0.1 s.  ...

Constraint based methods for allocation and scheduling of periodic applications

Alessio <1981> Bonfietti, Paola Mello
2013
Results show that the approach can handle realistic instances in terms of size and complexity. Next, we tackle the Cyclic Resource-Constrained Scheduling Problem (i.e. CRCSP).  ...  Many traditional approaches to cyclic scheduling operate by fixing the period value and then solving a linear problem in a generate-and-test fashion.  ...  Other approaches combine off-line/on-line scheduling techniques.  ...
