Modal Characteristics of Composite Beams with Single Delamination- A Simple Analytical Technique

In the present research, the effects of delamination size and location on vibration characteristics of laminated composite beams are investigated both analytically and numerically. In the analytical method, the delaminated beam is modeled as four interconnected Euler–Bernoulli beams and the constrained and free mode models are both simulated. The differential stretching and the bending-extensio...

A Novel Reordering Write Buffer to Improve Write Performance of Log-Structured File Systems

This paper presents a novel reordering write buffer which improves the performance of Log-structured File Systems (LFS). While LFS has a good write performance, high garbage-collection overhead degrades its performance under high disk space utilization. Previous research concentrated on how to improve the efficiency of the garbage collector after data is written to disk. We propose a new method...

Write-Optimized Indexing for Log-Structured Key-Value Stores

The recent shift towards write-intensive workload on big data (e.g., financial trading, social user-generated data streams) has pushed the proliferation of the log-structured key-value stores, represented by Google’s BigTable, HBase and Cassandra; these systems optimize write performance by adopting a log-structured merge design. While providing keybased access methods based on a Put/Get interf...

Optimal Write Batch Size in Log-Structured File Systems

Log-structured file systems create a performance benefit by maximizing the rate at which disk write operations can occur. However, this benefit comes at the expense of individual read operations, which can experience long queuing delays due to batched write service. This paper presents an analytic derivation of the write batch size that minimizes read response time, while retaining the benefit ...
