This paper presents the design, implementation, and evaluation of BORG, a self-optimizing storage system that performs automatic block reorganization based on the observed I/O workload. BORG is motivated by three characteristics of I/O workloads: non-uniform access frequency distribution, temporal locality, and partial determinism in non-sequential accesses. To achieve its objective, BORG manag...
The inter-relationship between the perception of bronchoconstriction, bronchial hyper-responsiveness and temporal adaptation in asthma is still a matter of debate. In a total of 52 stable asthmatic patients, 32 without airway obstruction ¿forced expiratory volume in 1 s (FEV(1))/vital capacity (VC) 84.1% (S.D. 7.9%), and 20 with airway obstruction [FEV(1)/VC 60% (4%)], we assessed the perceptio...
مقدمه: هدف از پژوهش حاضر بررسی رابطه حجم کار و کنترل بر کار با تعادل کار ـ زندگی است. روش: جامعه آماری این پژوهش، کلیه مدیران، روسا، سرپرستان، کارشناسان، کارمندان و کارگران گروه صنعتی میباشد، که نمونهای به حجم 333 نفر از آنها بهصورت تصادفی طبقهای انتخاب شدهاند. ابزار بهکار برده شده برای سنجش حجم کار، مقیاس 11 آیتمی کوک و روسو، برای کنترل بر کار، دو مقیاس گانستر و دوایر و جکسون و همکارا...
Dyspnoea differs between subjects with chronic obstructive pulmonary disease (COPD) and asthma, partly because the underlying mechanisms for bronchoconstriction differ. This study investigated the possible role of inflammation and the contribution of clinical variables on dyspnoea in subjects with COPD and asthma. Forty-eight smoking subjects with COPD and 21 nonsmoking subjects with asthma, we...
This study introduces the Borg multi-objective evolutionary algorithm (MOEA) for many-objective, multimodal optimization. The Borg MOEA combines ε-dominance, a measure of convergence speed named ε-progress, randomized restarts, and auto-adaptive multioperator recombination into a unified optimization framework. A comparative study on 33 instances of 18 test problems from the DTLZ, WFG, and CEC ...
The purpose of our study was to evaluate the reproducibility of a Borg rating of dyspnea in patients with COPD. We examined nine patients with COPD who performed a SST on four separate days within a ten-day period. The patients walked on a treadmill for 6 min. At the end of each minute, patients matched a Borg rating to the intensity of their breathlessness. We measured the HR, VE, VO2, VT and ...
