1. Performance Evaluation of Data Migration Policies for a Distributed Storage System with Dynamic Tiering

Atsushi Nunome, Hiroaki Hirata
Pages: 1 - 8
We have proposed a distributed storage system which autonomously migrates data blocks into a suitable storage node by considering their access frequency and read/write ratio. In this paper, we show that revised data migration policies can rapidly distribute input/output (I/O) hot spot over the storage...

2. Enhancement of Copper Wire Lengthening Automatic System using Contactless Heater

Hsiung-Cheng Lin, Jhih-Yao Hu, Chung-Hao Cheng
Pages: 9 - 15
Copper wire can be elongated to a very thin size like 0.01 mm from an original 0.6 mm via wire drawing dies. Although automatic machines are available for wire elongating process, the wire threading through dies still requires a human operation before entering an automation process. This procedure may...

3. Toward Affordable and Practical Home Context Recognition: –Framework and Implementation with Image-based Cognitive API–

Sinan Chen, Sachio Saiki, Masahide Nakamura
Pages: 16 - 24
To provide affordable context recognition for general households, this paper presents a novel technique that integrate image-based cognitive Application Program Interface (API) and light-weight machine learning. Our key idea is to regard every image as a document by exploiting “tags” derived by the API....

4. Multi-Dimensional Indexing System Considering Distributions of Sub-indexes and Data

Kazuto Nakanishi, Teruhisa Hochin, Hiroki Nomiya, Hiroaki Hirata
Pages: 25 - 33
This paper experimentally evaluates the parallel multi-dimensional indexing system indexing data by using several multi-dimensional indexes and retrieving required data from them in parallel. A constant number of data are indexed into a sub-index. The sub-index is inserted into an index in a computational...

5. Proposal and Prototype of DNS Server Firewall with Flexible Response Control Mechanism

Hideo Masuda, Shun Segawa, Masayuki Mori
Pages: 34 - 40
Domain Name System (DNS) is an important system for the Internet communication. DNS is a system for distributed management and operation of domain names, and it is possible to associate with the resources such as IP address, instruct the destination host of the e-mail, and so on. On the one hand, it...

6. Machine Learning in Failure Regions Detection and Parameters Analysis

Saeed Abdel Wahab, Reem El Adawi, Ahmed Khater
Pages: 41 - 48
Testing automation is one of the challenges facing the software development industry, especially for large complex products. This paper proposes a mechanism called Multi Stage Failure Detector (MSFD) for automating black box testing using different machine learning algorithms. The input to MSFD is the...
