In this randomized controlled animal study, standardized lesions on parietal peritoneum of rats were created by sandpaper and three interrupted sutures. Afterwards, the lesions were treated with Seprafilm, Interceed, Pr...
متن کاملThe Generalized CEM Algorithm
We propose a general approach for estimating the parameters of latent variable probability models to maximize conditional likelihood and discriminant criteria. Unlike joint likelihood, these objectives are better suited for classiication and regression. The approach utilizes and extends the previously introduced CEM framework (Conditional Expectation Maximization), which reformulates EM to hand...
متن کاملCEM - A Conceptual Email Manager
CEM is an email management system which stores its email in a concept lattice rather than in the usual tree structure. By using such a conceptual multi-hierarchy, the system provides more flexibility in retrieving stored emails. The paper presents the underlying mathematical structures, discusses requirements for their maintenance and presents their implementation.
متن کاملRethinking Software Metrics Rethinking Software Metrics Evaluating Measurement Schemes Cem Kaner on Cem Kaner On
Perhaps the most respected book on measurement in computing, Fenton and Pfleeger’s Software Metrics: A Rigorous and Practical Approach, defines measurement as follows: “Measurement is the process by which numbers or symbols are assigned to attributes of entities in the real world in such a way as to describe them according to clearly defined rules.” The problem with this definition is that ther...
متن کاملMicrowave Imaging Using SAR
Polarimetric Synthetic Aperture Radar (Pol.-SAR) allows us to implement the recognition and classification of radar targets. This article investigates the arrangement of scatterers by SAR data and proposes a new Look-up Table of Region (LTR). This look-up table is based on the combination of (entropy H/Anisotropy A) and (Anisotropy A/scattering mechanism α), which has not been reported up now. ...
