Profile-driven optimization can produce substantial improvements in the quality of code produced by a compiler or link-time optimizer. In this work, we analyze several important aspects of profile-driven optimization. We examine the effectiveness of profile-driven optimization in two commercial-quality optimizers (Digital’s GEM compiler and the link-time optimizer ‘alto’). We perform analyses t...

abstract profile monitoring in statistical quality control has attracted attention of many researchers recently. a profile is a function between response variables and one or more independent variables. there have been only a limited number of researches on monitoring multivariate profiles. indeed, monitoring correlated multivariate profiles is a new subject in the fileld of statistical process...

the study was carried out to investigate the effects of camelia (camelina sativa l. crantz) variety (cs) oil or seeds on performance, meat quality, immunity and plasma metabolic profile in broiler chickens. the broilers (n= 2,080, cobb 500) were randomly allocated (sex ratio 1:1) for 32-day experimental periods (from 11d to 42 d) to 4 experimental groups: control (corn-soybean meal-full fat soy...

As the Android platform is widely used for embedded systems including smart mobile devices, the needs for systematic performance analysis have significantly increased. System performance is usually measured by benchmarks and profiler software. We studied on the performance of Android platform using a benchmark application and public profile software. For more detail and integrated performance a...

a 42-day study was conducted to evaluate the influence of full-fat flaxseed (fs) and canola seed (cs) on broiler performance, fatty acid (fa) profile of meat, serum lipid content and antibody response to sheep red blood cells antigen (srbc). a total of 324 one-day-old chicks were attributed to 6 experimental groups. c: control (soybean-corn); cs1:7.5% cs; cs2:15% cs; cs-fs:10% fs + 10% cs; fs1:...

The ESTREAM project has identified two profiles for stream ciphers: a hardware profile and a software profile. The software profile is directly applicable to many computer systems. The hardware profile, on the other hand, does not reflect a complete system design, but instead represents a stand-alone component. In this paper we consider the integration of hardware stream ciphers in software sys...

In this paper, we describe the design of a profile generator toolkit, which aims to automatically create realistic user profiles for a mobile personalized portal service. These profiles simulate actual user behavior and are utilized to experiment with a personalized crawling system, called eRACE. With the help of this tool, we will assess the performance and scalability of the eRACE system by c...

The performance of wireless wideband high data rate indoor communications systems is affected by the channel propagation conditions. In this context, the channel delay profile characteristics constitute a significant contraint by imposing an irreducible error rate which results in a limitation of the transmission rate. In this paper, we examine the effects of equalization techniques on the perf...

BACKGROUND Recently the special attention is given to psychological aspects of childhood obesity in overweight and obese children. The present pilot study aims to investigate the association of obesity and lipid profile with school performance among Iranian students. METHODS 69 middle school male students between the ages of 12 to 14 in 2009-2010 were studied. BMI was considered as the obesit...
