Using simple page placement policies to reduce the cost of cache fills in coherent shared-memory systems by M Marchetti( Book )

5 editions published in 1994 in English and held by 6 WorldCat member libraries worldwide

Abstract: "The cost of a cache miss depends heavily on the location of the main memory that backs the missing line. For certain applications, this cost is a major factor in overall performance. We report on the utility of OS-based page placement as a mechanism to increase the frequency with which cache fills access local memory in a distributed shared memory multiprocessor. Even with the very simple policy of first- use placement, we find significant improvements over round-robin placement for many applications on both hardware and software-coherent systems. For most of our applications, dynamic placement allows 35 to 75 percent of cache fills to be performed locally, resulting in performance improvements of 20 to 40 percent. We have also investigated the performance impact of more sophisticated policies including hardware support for page placement, dynamic page migration, and page replication. We were surprised to find no performance advantage for the more sophisticated policies; in fact in most cases performance of our applications suffered."

Open loop load pull arrangement with determination of injections signals: by M Marchetti( )

1 edition published in 2009 in English and held by 1 WorldCat member library worldwide

Measurement arrangement and method for active load pull measurements of a device under test (1). A wideband analog-to-digital conversion block (3) is provided for obtaining measurement data. First and second injection signal generators (7, 8) are connected to a source side and a load side of the device under test (1). This set up allows to create predetermined reflection coefficients at reference planes of the device under test (1). Injection signal parameters as determined are converted into the injection signals at the source and load side by digital-to-analog conversion. The wideband analog-to-digital conversion block (3) is further arranged for analog-to-digital conversion of the intermediate frequency signals to obtain the actual measured reflection coefficient versus frequency functions with a first frequency resolution. The first frequency resolution applied in the analog-to-digital conversion is equal to or better than a second frequency resolution applied in the digital-to-analog conversion
Plastic Envelope in Propagating Crack Wake on Al-Li Alloys Subjected to Fatigue Cycles and to Different Heat Treatments( Book )

1 edition published in 2000 in English and held by 1 WorldCat member library worldwide

The aim of this research is to study the fracture behavior of three Al-Li alloys (2091-2195-8090), using standard CT specimens, in the frequency range of 1-10 Hz. Each of these three alloys is subjected to different heat treatments and its homogeneity is analyzed, before and after treatments, by Scanning Electron Microscope (SEM). Crack tip opening displacements and plastic zone envelope analyses are fully treated by experimental and numerical results and fatigue crack growth process is extensively reported. At the end of fatigue tests, specimen fracture surfaces have been deeply analyzed by SEM in order to individualize the characteristics of fracture as function of frequency, DELTA KAPPA and load ratio R

Tumor intracerebral primario mixto: gliosarcoma; correlacion anatomo-clinica by N Goldenberg( )

1 edition published in 1986 in Spanish and held by 1 WorldCat member library worldwide

El caso presentado corresponde a una paciente portadora de una extensa lesion con caracteristicas macroscopicas de meningioma, pero cuyas caracteisticas microscopicas son las de una neoplasia bifasica, con dos tejidos malignos de distinta estirpe, una glial y otra mesenquimatica, y marcada hiperplasia de los vasos sanguineos. Con respecto a los pocos casos reportados en la literatura, el referido no difiere salvo en la edad de presentacion. Es de destacar que la edad, sexo, cuadro clinico, evolucion y pronostico de los gliosarcomas son, esencialmente, los del glioblastoma sin componente sarcomatoso. Se ha mencionado como diferencia entre ambos, la mayor frecuencia de presentacion en el lobulo temporal, su aspecto bien circunscripto y un mayor potencial metastatico (pulmon e higado). Los tumores primarios intracerebrales constituidos por dos tejidos malignos de diferente estirpe, una glial y otra mesenquimatica han sido descriptos en la literatura hace casi noventa anos, cuando Stroebe (15) se refiere a tumores de origen glial con un componente sarcomatoso, derivado posiblemente de la pared de los vasos sanguineos, proponiendo el termino "gliosarcomas" para este tipo de neoplasias. El desarrollo de las mismas ha sido estudiado por Feigin (1, 2) y Rubinstein (13), entre otros autores. El primero propone la transformacion sarcomatosa a partir de la pared de los pequenos vasos, distintivamente hiperplasica en los glioblastomas, estimando que este tipo de transformacion ocurriria excepcionalmente (2% de los gliomas francamente anaplasicos). El objetivo del presente trabajo es presentar un caso de tumor intracerebral primario mixto ("gliosarcoma"), comentando sus aspectos clinicos y anatomopatologicos mas destacados y efetuando la correlacion de los mismos (AU)

Vigilancia epidemiologica de las infecciones intrahospitalarias: estudios sistematizados de prevalencia (1993-1994) by R Quiros( )

1 edition published in 1995 in Spanish and held by 1 WorldCat member library worldwide

A partir de la sistematizacion de los estudios de prevalencia en 1993, continuamos con la presentacion de los datos obtenidos en 1994, en conjunto con los del peiodo anterior. Esto permite tener una visualizacion grafica de los resultados obtenidos pudiendose analizar asi sus tendencias. Si bien la metodologia basica de los estudios no se ha modificado, a partir de diciembre de 1993 se incorporo al analisis, un sistema subjetivo que permite estratificar el nivel de gravedad de los pacientes y relacionarlo con el riesgo de infeccion intrahospitalaria. Este modelo fue validado a partir de los estudios de diciembre de 1993, abril y agosto de 1994, evaluandose ademas su reproducibilidad. El analisis comparativo de los estudios de prevalencia, muestra la persistencia de una proporcion elevada de pacientes con acceso vascular (>50 por ciento) y cateter urinario (>20 por ciento), lo que determina un riesgo incrementado de desarrollar infecciones asociadas a estos factores. La tasa de prevalencia de infecciones intrahospitalarias se mantuvo por encima del 10 por ciento ... (AU)

Use of National Forest Inventories to downscale European forest diversity spatial information in five test areas, covering different geo-physical and geobotanical conditions( )

1 edition published in 2010 in English and held by 0 WorldCat member libraries worldwide

The project "Use of National Forest Inventories to downscale European forest diversity spatial information in five test areas, covering different geo-physical and geo-botanical conditions", referred also as "forest downscaling" (JRC contract 382340 F1SC) covers one of the seven topics that have been studied in the frame of the Regulation (EC) 2152/2003 on the monitoring of forest and environmental interactions, the socalled "Forest Focus" Regulation. This study was conducted by a European consortium coordinated by the Italian Academy of Forest Sciences (Italy) and included partners from the Swedish University of Agricultural Sciences, the Institute of Forest Ecosystem Research of the Czech Republic, the German Federal Research Centre for Forestry and Forest Products, and the Swiss Federal Institute for Forest, Snow and Landscape Research. The overall supervision of the project and the processing of forest spatial pattern were done by the Joint Research Centre. This study addressed the link between field based forest biological diversity data and landscape-level forest pattern information. The former were made available from National Forest Inventories (NFIs) at plot level in five different countries; their harmonisation was implemented for the first time and benefited from outcomes of the COST Action-E43 on core biodiversity variables. For the latter, landscape level forest spatial pattern maps were automatically derived from available remote sensing based forest cover maps. The relation-ships between selected pattern and biodiversity variables available from the two different data sources were studied. Seven case studies for a total area of about 100,000 km2 were selected in five European ecological regions: one site in Germany (Atlantic zone), one in Sweden (Boreal zone), two in Czech Republic (Continental zone), one in Switzerland (Alpine zone) and two in Italy (Mediterranean zone)
