Resumen. La estrategia de una casa de empeño puede monitorearse de manera efectiva utilizando un cuadro de mando conectado en tiempo real a tableros de control. El cuadro de mando se implementa utilizando QlikView y visualiza los indicadores clave de desempeño definidos para la casa de empeño para el tema estratégico de servicio. La implementación realizada siguió la metodología de Ciclo de Vid...

Casa Siloé (Siloam House) is a Catholic support house that shelters children with human immunodeficiency virus or acquired immunodeficiency syndrome. The article presents a history of the institution and discusses its work. A qualitative approach was used, relying on oral history techniques and documental analysis. Eight key informants were interviewed: the president of the institution, two coo...

SUMMARY A public server for evaluating the accuracy of protein sequence alignment methods is presented. CASA is an implementation of the alignment accuracy benchmark presented by Sauder et al. (Proteins, 40, 6-22, 2000). The benchmark currently contains 39321 pairwise protein structure alignments produced with the CE program from SCOP domain definitions. The server produces graphical and tabula...

Computational Auditory Scene Analysis (CASA) aims to model our ability to structure our acoustical environment. In a CASA context, this paper deals with a method for time-frequency labeling based on harmonic properties. The method is based on a classical pitch extraction algorithm, termed the « zerocrossing method », which is known to be particularly sensitive to any kind of interference. This ...

Background: In mammalian spermatozoa, motility is one of the most important parameters for evaluating the quality of the semen. From a functional point of view, motility is strongly related to the spermatozoa’s ability to manage its energy status, Thus, modulation of energy status could be translated into significant changes in motility patterns. The aim of the present study was to evaluate xyl...

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...

در این مقاله، روش جدیدی برای تخمین نسبت سیگنال به نویز (snr) سیگنال ترکیب ارائه شده است که بر پایه روش آنالیز ترکیب شنیداری محاسباتی (casa) است. در روش ارائه شده، ماسک باینری ایده آل (ibm) که به طور معمول هدف محاسباتی سیستم های مبتنی بر casa است، برای تخمین snr سیگنال گفتار نویزی به کار گرفته می شود. روش پیشنهادی با استفاده از ibm و چندین ماسک شبه ibm ارزیابی شده است. این روش، ساده و از نظر محا...

Microbiological characterization of frescos in four different locations (Collegio degli Augustali, Casa del Colonnato Tuscanico, Casa dello Scheletro and Casa del Gran Portale) of excavation sites of Herculaneum was carried out. The use of infrared thermography allowed detecting sample points on frescos with greatest moisture not visible to the naked eye, resulting in structural damage. The mic...
