This paper proposes to use the Laplace-Beltrami spectrum (LBS) as a global shape descriptor for medical shape analysis, allowing for shape comparisons using minimal shape preprocessing: no registration, mapping, or remeshing is necessary. The discriminatory power of the method is tested on a population of female caudate shapes of normal control subjects and of subjects with schizotypal personal...

Past research revealed issues with artificial event data used for comparative analysis of process mining algorithms. The aim of this research is to design, implement and validate a framework for producing artificial event logs which should increase discriminatory power of artificial event logs when evaluating process discovery techniques.

BACKGROUND Osteoarthritis of the knee is related to many correlated mechanical factors that can be measured with gait analysis. Gait analysis results in large data sets. The analysis of these data is difficult due to the correlated, multidimensional nature of the measures. METHODS A multidimensional model that uses two multivariate statistical techniques, principal component analysis and disc...

We present an analytical packet/ow-level modelling approach for the performance analysis of IEEE 802.11e WLAN, where we explicitly take into account QoS di erentiation mechanisms based on minimum contention window size values and Arbitration InterFrame Space (AIFS) values, as included in the Enhanced Distributed Channel Access (EDCA) protocol of the 802.11e standard. We rst enhance the packet...

The ever-growing malware threat in the cyber space calls for techniques that are more effective than widely deployed signature-based detection systems and more scalable than manual reverse engineering by forensic experts. To counter large volumes of malware variants, machine learning techniques have been applied recently for automated malware classification. Despite the successes made from thes...

Muslims in France: Identifying a Discriminatory Equilibrium We analyze the assimilation patterns of Muslim immigrants in Western countries with a unique identification strategy. Survey and experimental data collected in France in 2009 reveal that Muslims and rooted French are locked in a sub-optimal equilibrium whereby (i) rooted French exhibit taste-based discrimination against those they are ...

Mycobacterium avium subsp. paratuberculosis is the etiologic agent of Johne's disease and is endemic to the national cattle herds of many countries. Because of the very low level of genetic heterogeneity of this organism, it is difficult to select a workable procedure for strain differentiation at a resolution sufficient to investigate epidemiological links between herds or different ruminant s...
