FLEX is a new cost e ective, \locality aware" load balancing solution for a shared web hosting service implemented on a cluster of machines [3]. FLEX allocates hosted web sites to di erent machines in the cluster based on the sites' processing and memory requirements which are estimated using the site logs. Appropriate routing of requests can be achieved by using the DNS infrastructure, since e...

FLEX is a concept for a fully OH suppressed near infrared integral field spectrograph, being developed at the AAO. FLEX will be the first instrument to employ fibre Bragg gratings for OH suppression, a radical new technology which cleanly suppresses the atmospheric OH emission lines at 30dB whilst maintaining a high overall throughout of ~90%. In this paper we simulate the expected performance ...

INTRODUCTION The use of videolaryngoscopes is recommended for morbidly obese patients. The aim of the study was to evaluate the Levitan FPS optical stylet (Levitan) vs Lafy-Flex videolaryngoscope (Lary-Flex) in a group of MO patients. METHODS Seventy-nine MO (BMI > 40 kg m(-2)) patients scheduled for bariatric surgery were included in the study and randomly allocated to the Levitan FPS or Lar...

FLEX is a user interface to relational databases that can be used satisfactorily by users with different levels of expertise. FLEX is based on a formal query language, but is tolerant of incorrect input. It never rejects queries; instead, it adapts flexibly and transparently to their level of correctness and well-formedness, providing interpretations of corresponding accuracy and specificity. T...

Purpose To evaluate the biomechanical stability of ex vivo porcine corneas after femtosecond lenticule extraction (FLEx) and small incision lenticule extraction (SmILE) refractive surgeries. Methods Forty-five porcine eyes were equally divided into three groups: Groups 1 and 2 were treated with FLEx and SmILE procedure, respectively. Group 3 served as control. A refractive correction of -14 d...

We consider the problem of creating plane orthogonal drawings of 4-planar graphs (planar graphs with maximum degree 4) with constraints on the number of bends per edge. More precisely, we have a flexibility function assigning to each edge e a natural number flex(e), its flexibility. The problem FLEXDRAW asks whether there exists an orthogonal drawing such that each edge e has at most flex(e) be...

FLEX is a user interface to relational databases that is tolerant of incorrect input. FLEX never rejects a query; instead, it adjusts to the level of technical expertise its users seem to possess (as judged from their input). In particular, FLEX understands formal queries; salvages incorrect queries if they include enough clues on their intended meaning; suggests educated guesees if it recogniz...

FLEX is a new scalable “locality aware” solution for achieving both load balancing and efficient memory usage on a cluster of machines hosting several web sites. FLEX allocates the sites to different machines in the cluster based on their traffic characteristics. This aims to avoid the unnecessary document replication to improve the overall performance of the system. The desirable routing can b...
