Design of Experiments (DOE)—A Valuable Multi-Purpose Methodology  [PDF]
Miryam Barad
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.514206
Abstract: The DOE methodology is an effective tool for upgrading the level of measurement and assessment. In any design, planning or control problem the designer is faced with many alternatives. He/she is challenged to develop design approaches that can meet both quality and cost criteria. The way experiments are designed greatly affects the effective use of the experimental resources and the easiness with which the measured results can be analyzed. This paper does not present new evidence based on designed experiments. Its objective is solely to show how useful application of multifactor experiments is in a variety of circumstances and decision making scenarios. The paper reviews three published examples where this method was used in different contexts: quality control, flexible manufacturing systems (FMS) and logistics systems. The physical experiment has been carried out to improve the quality of a special type of batteries. The simulation experiment has been carried out to investigate the impact of several flexibility factors in a flexible manufacturing system. The numerical value of a complex analytical expression representing a customer oriented logistics performance measure has been calculated for different values of its parameters, i.e. the given numerical values of the investigated factors. It enabled a methodical examination of all factor effects and especially their interactions, thus shedding light on complex aspects of the logistics decision problem. In these examples, cases from different contexts were presented, enabling to view design of experiments as a powerful ingredient for improving decision making in a variety of circumstances.
Petri Nets—A Versatile Modeling Structure  [PDF]
Miryam Barad
Applied Mathematics (AM) , 2016, DOI: 10.4236/am.2016.79074
Abstract: Petri Nets (PNs) are an effective structure for modeling and analyzing asynchronous systems with concurrent and parallel activities. A Petri net models the static properties of a discrete event system concentrating on two basic concepts: events and conditions. Most of the theoretical work on Petri nets is a formal definition of Petri nets structures, which consist of a set of places, representing conditions, a set of transitions, representing events, an input function and an output function. For practical purposes, a graphical representation is more useful. Two types of nodes portray places and transitions. A circle is a place and a bar is a transition. There is no inherent measure of time in a classical Petri net. To approach time-based evaluation of system performances, Timed Petri Nets (TPNs) were introduced. Modeling the notion of time is not straightforward. There are several possibilities for introducing time in PNs, among them timed transitions and timed places. This paper reviews several published examples where Petri Nets were used in different circumstances such as estimating expected utilization of processing resources at steady state in open queueing networks, verifying computerized simulations and batch planning in textile industry.

Revista de Saúde Pública , 1993, DOI: 10.1590/S0034-89101993000200007
Abstract: with the intention of verifying the presence of t. sordida st?l 1859 in urban ecotopes in corrientes city, argentina, both, human dwellings and an extradomiciliary habitat were taken as a basis. a complete t. sordida population census was carried on in mitre park pigeon house and 400 pigeon nests (columbia livia) were dissected. the triatomineos samples that had been detected in human dwellings were sent to the arthropods laboratory by their inhabitants. these triatomineos were classified systematically and according to their age class. their feces were examined under a microscope 400 x, so as to identify trypanosoma cruzi. six eggs, 45 first-instar nymphs, 110 second-instar nymphs, 226 third-instar nymphs, 303 fourth-instar nymphs, 1.103 fifth-instar nymphs, 12 females and 11 males were collected from the pigeon house. the presence of this species was verified in the 27 houses, situated in 8 different neighborhoods in the city; 13 eggs, 33 different instar nymphs, 27 females and 9 males were captured, 82 samples altogether. no triatomineo was infected by t. cruzi. t. sordida, adults moved towards the houses in spring and summer. of the material found in human dwellings 33% was female. the adaptation of t. sordida to extra-domestic habitats and their tenfency to invade human houses has thus been verified. this fact should be taken into account in vector control programs.
Life cycle and reproductive patterns of Triatoma rubrovaria (Blanchard, 1843) (Hemiptera: Reduviidae) under constant and fluctuating conditions of temperature and humidity

Revista da Sociedade Brasileira de Medicina Tropical , 2005, DOI: 10.1590/S0037-86822005000500014
Abstract: the aim of this study was to evaluate the temperature and relative humidity influence in the life cycle, mortality and fecundity patterns of triatoma rubrovaria. four cohorts with 60 recently laid eggs each were conformed. the cohorts were divided into two groups. in the controlled conditions group insects were maintained in a dark climatic chamber under constant temperature and humidity, whereas triatomines of the ambiental temperature group were maintained at room temperature. average incubation time was 15.6 days in the controlled conditions group and 19.1 days in the ambiental temperature. in group controlled conditions the time from egg to adult development lasted 10 months while group ambiental temperature took four months longer. egg eclosion rate was 99.1% and 98.3% in controlled conditions and ambiental temperature, respectively. total nymphal mortality in controlled conditions was 52.6% whereas in ambiental temperature was 51.8%. mean number of eggs/female was 817.6 controlled conditions and 837.1 ambiental temperature. fluctuating temperature and humidity promoted changes in the life cycle duration and in the reproductive performance of this species, although not in the species mortality.

Revista de Saúde Pública , 1993,
Abstract: Con el objeto de verificar la presencia de T. sordida St l 1859, en ecotopos urbanos de la ciudad de Corrientes, Argentina se tomaron como base un habitat extradomiciliario y la vivienda humana. En el palomar situado en el Parque Mitre fue realizado un censo completo de población de T. sordida para lo cual fueron disecados 400 nidos de paloma (Columbia livia). Los ejemplares de triatominos detectados en las viviendas fueron enviados por los pobladores al Laboratorio de Artrópodos. Los triatominos fueron determinados sistemáticamente y por clase de edad. La materia fecal de los mismos fue examinada al microscopio para la identificación del Trypanosoma cruzi. En el palomar se colectaron: 6 huevos, 45 ninfas de primer estadío, 110 ninfas de segundo estadío, 226 ninfas de tercer estadío, 303 ninfas de cuarto estadío, 1.103 ninfas de quinto estadío, 12 hembras y 11 machos. Se constató la presencia de esta especie en 27 viviendas localizadas en 8 barrios de la Ciudad. Se capturaron 13 huevos, 33 ninfas de diferentes estadíos, 27 hembras y 9 machos, totalizando 82 individuos. Ningún triatomino resultó infectado por T. cruzi. Los adultos de T. sordida se desplazaron hacia el domicilio en primavera y verano. Es de destacar que el 33% del material hallado en las viviendas correspondió a hembras. Se ha comprobado la adaptación de T. sordida a un habitat extradomiciliario y su tendencia a invadir la vivienda humana, hecho que se debería ser tenido en cuenta en los programas de control de vectores.

Historia Actual Online , 2010,
Abstract: Este artículo se propone analizar ciertas particularidades de los Países de Renta Media latinoamericanos en el régimen de la Cooperación al Desarrollo. En esa dirección, toma en consideración, en primer lugar, la autopercepción de los países latinoamericanos como PRM y su reclamo por continuar siendo receptores de cooperación. En una segunda instancia, recoge los fundamentos sobre los que Espa a orienta prioritariamente su cooperación al desarrollo hacia aquéllos. En tercer término se ala semejanzas y singularidades que exhiben la Argentina y Chile en su condición de PRM en el espejo de la cooperación espa ola y remarca algunos ejemplos de cooperación que aquéllos desarrollan conjuntamente. Finalmente, presenta reflexiones y sugerencias para acciones futuras.

Yod : Revue des études Hébra?ques et Juives , 2011, DOI: 10.4000/yod.292
Abstract: Having defined Shoah literature as texts written by prisoners of ghettos and camps while they were imprisoned, the article focuses on a group of Yiddish texts of this type, drawn from a larger collection of unpublished texts written in various languages. It goes through the history of the perception of Shoah Yiddish poetry, which was first seen as plain testimony and progressively became an object of poetic analysis. The article presents the most common genres usually found in this type of poetry: adaptations, supporting poems, love poems, etc. A more specific classification is proposed, as well as an analysis which aims to link each genre with various aspects of traditional and modern Jewish culture. – . , . – , . – : . : , – , “ . . .
