Using high resolution displays for high resolution cardiac data
The ability to perform fast, accurate, high resolution visualization is fundamental
to improving our understanding of anatomical data. As the volumes of data
increase from improvements in scanning technology, the methods applied to rendering
and visualization must evolve. In this paper we address the interactive display of
data from high resolution MRI scanning of a rabbit heart and subsequent histological
imaging. We describe a visualization environment involving a tiled LCD panel
display wall and associated software which provide an interactive and intuitive user
interface.
The oView software is an OpenGL application which is written for the VRJuggler
environment. This environment abstracts displays and devices away from the
application itself, aiding portability between different systems, from desktop PCs to
multi-tiled display walls. Portability between display walls has been demonstrated
through its use on walls at both Leeds and Oxford Universities. We discuss important
factors to be considered for interactive 2D display of large 3D datasets,
including the use of intuitive input devices and level of detail aspects
Influence of protein concentration and coagulation temperature on rennet-induced gelation characteristics and curd microstructure
peer-reviewedThis study characterized the coagulation properties and defined the cutting window (CW; time between storage modulus values of 35 and 70 Pa) using rheometry for milk standardized to 4, 5, or 6% protein and set at 28, 32, or 36°C. Milks were standardized to a protein-to-fat ratio of approximately 1 by blending ultrafiltration retentate, skim milk, and whole milk. The internal curd microstructure for selected curd samples was analyzed with transmission electron microscopy and scanning electron microscopy. Lowering the coagulation temperature caused longer rennet coagulation time and time to reach storage modulus of 35 Pa, translating into a wider CW. It also led to a lower maximum curd-firming rate (MCFR) with lower firmness at 40 min at a given protein level. Increasing protein levels resulted in the opposite effect, although without an effect on rennet coagulation time at a given temperature. On coagulation at 28°C, milk with 5% protein resulted in a similar MCFR (âŒ4 Pa/min) and CW (âŒ8.25 min) compared with milk with 4% protein at 32°C, which reflects more standard conditions, whereas increasing milk to 6% protein resulted in more than doubling of the curd-firming rate (MCFR = 9.20 Pa/min) and a shorter CW (4.60 min). Gels set at 28°C had lower levels of rearrangement of protein network after 40 min compared with those set at 36°C. Protein levels, on the other hand, had no influence on the levels of protein network rearrangement, as indicated by loss tangent values. The internal structure of curd particles, as investigated by both scanning electron microscopy and transmission electron microscopy, appeared to have less cross-linking and smaller casein aggregates when coagulated at 28°C compared with 36°C, whereas varying protein levels did not show a marked effect on aggregate formation. Overall, this study showed a marked interactive effect between coagulation temperature and protein standardization of milk on coagulation properties, which subsequently requires adjustment of the CW during cheesemaking. Lowering of the coagulation temperature greatly altered the curd microstructure, with a tendency for less syneresis during cutting. Further research is required to quantify the changes in syneresis and in fat and protein losses to whey due to changes in the microstructure of curd particles arising from the different coagulation conditions applied to the protein-fortified milk
CAD/CAM, CNC TECHNOLOGY APPLIED IN THE FIELD OF ENGINEERING, SECURITY TECHNOLOGY AND MECHANICAL ENGINEER TRAINING I.
In the last decades the spectacular results of each
developmental stages of
computer-aided design, were considered as great magic of
computer use.
Professionals were shocked by the impressive building of
engineer works and
their more and more realistic appearance. It was hard to believe
and for many
people it still is that this technology becomes indispensable in
everyday
engineering work. By now, in front-rank product development, it
is impossible to
do a competitive designer work without applying the most up-to-
date design
technology. This all leads to the fact that an engineer student
of our days, in his
design practice, is definitely going to work with the
momentarily most up-to-date
technology, which will be out-of-date in a couple of years. |

Interactive Newsprint: The Future of Newspapers? Printed electronics meets hyperlocal and community co-design
The news industry is currently in a well-documented state of flux, with publishers from across the developed world examining new business models, reinterpreting existing relationships between their income streams and readers, while maintaining their ability to generate editorial output that is relevant and interesting to the communities they cover.
Interactive Newsprint seeks to add a new and revolutionary dimension to this media evolution by asking: can printed electronics and internet-enabled paper (technologies that utilise standard paper and printing processes and through conductive ink and battery power offer capacitive touch interactions similar to smartphones and tablets) create a new way of transmitting community-based news and information?
Utilising co-design techniques and practices, the project seeks to produce community- relevant hyperlocal text and audio content and place it on a centuries-old platform: the newspaper. As a result of the paper's internet connectivity, the project is also examining potential benefits of transplanting some online features such as analytic data on user interactions. Led by the School of Journalism, Media and Communication (JoMeC) at the University of Central Lancashire (UCLan), the 18-month, EPRSC-funded project is therefore examining the potential for community co-design and printed electronics to transform paper- based news and information for the 21st Century, along with revenue and data generation that is unique to digital formats such as websites, social networks, smartphones and tablets. Building on work carried out on the EPSRC-funded Bespoke project, researchers from UCLan, University of Dundee, University of Surrey and commercial printed electronics firm Novalia are prototyping a series of paper-based community news platforms that are populated by content produced by community reporters and generated through an iterative co-design process.
This paper will outline the methodology, technological potential of interactive newsprint and how the project is looking to embed analytic data into traditional printed-paper formats. It will also focus on how members of the Preston community are shaping both the news and platform over the 18-month process. As the project is mid-way through, the paper will present an overview of the project to date, outline the design methodology and describe and demonstrate the early-stage prototypes. The paper will also hint at new editorial construction practices as community and professional reporters all contribute to the hyperlocally-themed editorial output. The authors will present a discussion of the theoretical framework that underpins the project as a whole. In addition to the practical illustrations, the paper will outline the authors' initial thoughts on how interactive newsprint â through its internet connectivity and potential for data transfer â could revolutionise editorial and advertorial relationships
