The present study investigated the existing relationship between computer assisted semen motility parameters and gametes motility duration, known to express semen quality and fertilizing capacity in fish. The objective was particularly to identify computer aided semen analysis (CASA) parameters that could be used as potential fertility predictors. Semen samples were collected from the beginning...

Preoperative and postoperative sperm parameter values from infertile men with varicocele were analyzed by computer-aided sperm analysis (CASA) to assess if sperm characteristics improved after varicocelectomy. Semen samples of men with proven fertility (n = 38) and men with varicocele-related infertility (n = 61) were also analyzed. Conventional semen analysis was performed according to WHO (20...

In this work we develop a very simple batch learning algorithm for semiblind extraction of a desired source signal with temporal structure from linear mixtures. Although we use the concept of sequential blind extraction of sources and independent component analysis, we do not carry out the extraction in a completely blind manner; neither do we assume that sources are statistically independent. ...

Background: Although AI practices have been introduced little over 60 years, the success rate remains relatively low. This might be due to the exclusive selection of semen based on motility analysis. Recent advancement in sperm sexing using flow cytometry with an increased throughput from next generation cell sorters, made use of this technology in studding sperm qualitative aspects other than ...

We present here a general digital method to accelerate correlation-based digital background calibration in pipelined ADCs. The central task in correlation-based background calibration is the extraction of component mismatch information from correlated data sequences. Using an explicit frequency domain analysis, we treat the extraction process as discrete-time low pass filtering. We then show th...

In Software Product Line Engineering (SPLE) families of systems are designed, rather than developing the individual systems independently. Combinatorial Interaction Testing has proven to be effective for testing in the context of SPLE, where a representative subset of products is chosen for testing in place of the complete family. Such a subset of products can be determined by computing a so ca...

1 In August 2003, while many Europeans were heading to the beaches to mitigate the effects of the worst heat wave on record, José Eduardo Sampaio, the CEO of Casa XXI, was faced with another kind of heat. Cartão 21, the innovative payment system of Casa XXI that he had personally conceived and subcontracted, had dramatically failed on August 6 th during the high-visibility inauguration of Alval...

He Q., Ren Y., Mohamed I., Ali M., Hassan W., Zeng F. (2013): Assessment of trace and heavy metal distribution by four sequential extraction procedures in a contaminated soil. Soil & Water Res., 8: 71–76. Four sequential extraction procedures (Sposito, Tessier, Silveira and Bureau Communautaire de Reference (BCR)) were used to evaluate the distribution of some metals (Fe, Cu, Cd and Zn) in a co...
