Stress intensity factors under combined bending and torsion moments

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2012年第1期13卷 1-8页

This paper discusses stress intensity factor （SIF） calculations for surface cracks in round bars subjected to combined torsion and bending loadings. Different crack aspect ratios, a/b, ranging from 0.0 to 1.2 and relative crack depths, a/D, ranging from 0.1 to 0.6 were considered. Since the loading was non-symmetrical for torsion loadings, a whole finite element model was constructed. Then, the individual and combined bending and torsion loadings were remotely applied to the model. The equivalent SIF method, F＊EQ, was then used explicitly to combine the individual SIFs from the bending and torsion loadings. A comparison was then carried out with the combined SIF, F＊FE, obtained using the finite element analysis （FEA） under similar loadings. It was found that the equivalent SIF method successfully predicted the combined SIF for Mode I. However, discrepancies between the results determined from the different approaches occurred when Fm was involved. It was also noted that the predicted F＊ EE using FEA was higher than the F＊EQ predicted through the equivalent SIF method due to the difference in crack face interactions.

Intelligent Dynamic Aging Approaches in Web Proxy Cache Replacement

引用

Journal of Intelligent Learning Systems and Applications 2015年第4期7卷 117-127页

作者： Waleed Ali Siti mariyam Shamsuddin Department of Information Technology Faculty of Computing and Information Technology King Abdulaziz University Rabigh Kingdom of Saudi Arabia Faculty of Computing Universiti Teknologi Malaysia Johor Malaysia

One of commonly used approach to enhance the Web performance is Web proxy caching technique. In Web proxy caching, Least-Frequently-Used-Dynamic-Aging (LFU-DA) is one of the common proxy cache replacement methods, which is widely used in Web proxy cache management. LFU-DA accomplishes a superior byte hit ratio compared to other Web proxy cache replacement algorithms. However, LFU-DA may suffer in hit ratio measure. Therefore, in this paper, LFU-DA is enhanced using popular supervised machine learning techniques such as a support vector machine (SVM), a naive Bayes classifier (NB) and a decision tree (C4.5). SVM, NB and C4.5 are trained from Web proxy logs files and then intelligently incorporated with LFU-DA to form Intelligent Dynamic- Aging (DA) approaches. The simulation results revealed that the proposed intelligent Dynamic- Aging approaches considerably improved the performances in terms of hit and byte hit ratio of the conventional LFU-DA on a range of real datasets.

A Brief Report Investigating Subjective and Objective Memory Pre- and Post-Memory Training in 70- to 96-Year-Old Individuals with Mild Memory Deficit

引用

Advances in Aging Research 2015年第4期4卷 113-119页

作者： Peter A. Magaro Bruce Brotter mariyam Jalees Memory Training Centers of America New York NY USA

Subjective memory impairment is a major complaint among older adults;however, research is conflicting regarding the relationship between subjective memory impairment and objectively measured memory loss. Here, individuals with mild memory impairment completed the memory subscale of the Cognistat as a measure of objective memory, and the Memory Complaint Questionnaire (MCQ) as a measure of subjective memory, prior to and following a 3-month memory training program. Results revealed that individuals with more, compared with fewer, memory complaints performed worse on the Cognistat. Additionally, increased Cognistat performance fol-lowing the memory training procedure was associated with decreased MCQ measured complaints. There was suggestive evidence that the memory training procedure improved memory, and thus future research is warranted. These findings imply that older, memory-impaired, adults, despite their memory impairment, are indeed able to judge, and may be accurately concerned with, the extent of their own memory loss. It should be noted that serious statistical limitations here indicate the need for replication to confirm the validity of the findings.

Memory Training and Task Specificity in 90-99-Year-Old Seniors with Mild Cognitive Impairment

引用

Advances in Aging Research 2015年第1期4卷 1-12页

作者： Peter A. Magaro Bruce Brotter mariyam Jalees Memory Training Centers of America New York USA

Managing memory deficits is a central problem among older adults with mild cognitive impairment (MCI). This study examined the effects of memory training on memory performance in an understudied “oldest-old” population ranging in age from 90 to 99 years. Eighteen mild to moderately cognitive-impaired older seniors, 90 years and older were recruited from memory clinics established in senior living communities. Treatment sessions took place, on average, twice weekly, for 55 minutes. Memory intervention included nineteen computer-based exercises customized to focus on memory loss. The specificity of memory training was very clear;memory training produced significant effects (F(3,51) = 2.81, p = 0.05) on memory performance, especially after 6 months of training, while other outcome measures showed no effects as predicted. Based on the results, it can be concluded that interventions targeting cognition and memory in the oldest-old MCI population can significantly improve memory function and reduce cognitive deficits.

Nine Months of Memory Training Increases Cognistat Measured Memory in 79 - 89 Year-Old Mild Cognitively Impaired Individuals

引用

Advances in Aging Research 2015年第3期4卷 79-88页

作者： Peter A. Magaro Bruce Brotter mariyam Jalees Memory Training Centers of America New York NY USA

The effects of a memory training paradigm on performance across multiple cognitive domains, measured via the Cognistat, in 70 - 89 year-old individuals with mild cognitive impairment (MCI), were examined. Memory training sessions were conducted on average twice weekly, for 55 minutes each session, for 9 months. Across the testing period, Cognistat-measured memory increased relative to performance in other cognitive domains. Additionally, performance on non-memory measures remained stable or declined. Thus, memory training in older adult, MCI individuals may result in improved memory, but not in improvement in other, non-memory, cognitive domains. Results replicate previous work examining “oldest-old” individuals ranging in age from 90 to 99 years old at the time of study start.
