The paper describes an active prodder for the recognition of touched materials. The proposed system has been developed with feedback from deminers expertise, keeping into consideration their remarks from past research activities for a better understanding of the reasons for failures in the adoption of the previously developed prodders. It is important to underline that this intelligent prodder ...

In recent times there has been a proliferation of activity in the area of flexible learning for tertiary institutions [l], [2], [3]. Some of the reasons for this interest are that 1) students have more options as to when and how they will learn, 2) distance education is far more practical, 3) staff teaching time can be reduced substantially in the long term, and 4) the computer animation achiev...

In this paper we present the development of a magnetic moment reference material for low moment magnetic samples. We first conducted an inter-laboratory comparison to determine the most useful sample dimensions and magnetic properties for common instruments such as vibrating sample magnetometers (VSM), SQUIDs, and alternating gradient field magnetometers. The samples were fabricated and then me...

Polycrystalline alumina developed by the Japan Fine Ceramics Center (JFCC) has been studied as a candidate thermal diffusivity reference material. It was experimentally confirmed that the alumina developed by the JFCC is homogeneous and stable enough to be used as a reference material. The thermal diffusivities of two specimens of different thicknesses (2 and 3 mm) were measured by the laser fl...

In this paper we discuss our experiences in creating lectures-on-demand using Flash streams based on MS PowerPoint slides that are enriched by author’s comments (audio as well as video streams). We depict the drawbacks concerning up-to-dateness of lecture content and compatibility with different desktop and mobile devices. According to this, we focus on our workflow to create lectures using pod...

Environmental problems have attracted worldwide attention, and the recognition of their importance has risen through the newspapers and other media every day. In the construction industry, industrial waste resulting from civil engineering work has become a big problem, termed construction pollution. Construction sludge and muddy water resulting from construction or demolition are particularly d...

Green Toxicology refers to the application of predictive toxicology in the sustainable development and production of new less harmful materials and chemicals, subsequently reducing waste and exposure. Built upon the foundation of "Green Chemistry" and "Green Engineering", "Green Toxicology" aims to shape future manufacturing processes and safe synthesis of chemicals in terms of environmental an...

Magnesium based alloys possess a natural ability to biodegrade due to corrosion when placed within aqueous substances, which is promising for cardiovascular and orthopedic medical device applications. These materials can serve as a temporary scaffold when placed in vivo, which is desirable for treatments when temporary supportive structures are required to assist in the wound healing process. T...
