Recently developed optical inspection tools provide images from the inside of natural gas pipelines to monitor pipeline integrity. The vast amounts of data generated prohibits human inspection of the resulting images. We designed an image processing and classification method to identify abnormal events. Non-overlapping image blocks are classified into twelve categories: normal, black line, grin...

A likely feature of the Internet classroom is automated assessment of student exercises. In this paper, we describe the design and implementation of the Grade Grinder, an Internet-based assessment service developed for use with logic-teaching courseware. We discuss the utility of this platform both as a pedagogical resource, and as a provider of data for research on student problem-solving. We ...

I introduce the idea of the “algorithms studio,” a novel approach to integrating algorithm visualiza-tion technology into undergraduate courses on algorithms. I then present a five-year research project,funded by the National Science Foundation, for developing and empirically evaluating the idea. Fi-nally, I report on the current status of the research. 132Second Program Vis...

Abstract. Microstructured sago (Metroxylon sagu) possesses an excellent potential to be used for numerous applications. In this paper, starch microparticles (SMPs) were fabricated using ultra-fine grinder without any chemical treatments or purification steps thus making it a “green” and eco-friendly procedure. The effects on increasing the numbers of passages through resulting SMPs as suspensio...

Abrasive machining is a widely employed finishing process for different materials such as metals, ceramics, glass, rocks, etc to achieve close tolerances and good dimensional accuracy and surface integrity. High efficiency abrasive machining is one of the important techniques of advanced manufacture. Combined with raw and finishing machining, it can attain high material removal rate like turnin...

In this paper, a thought and method of dynamic optimizadon design is presented.

This study is part of the ongoing national Bioenergy Research Programme in Finland. The study looked into the quality of chips made of logging residues composed predominantly of spruce wood. In addition, the productivity of the Evolution 910R chipper, the MOHA chipper truck, and the Morbark 1200 tub grinder was studied. The three machines studied were capable of producing acceptable chips for h...

Foot complications are common in people with diabetes. Ulcers often become infected and, if not treated promptly, can result in sepsis and gangrene requiring amputation. The specialised nursing intervention in this study varied according to the assessed risk. Patients with diabetic neuropathy received treatment every six months. This comprised toenail cutting, trimming of trichophytic nail with...
