A Study In The Use Of Elastic Materials In Expandable Containment Units, Andrew J. Eisenman, Joby Anthony Iii, David Satagaj

Montview Liberty University Journal of Undergraduate Research

The rigidity of materials in conjunction with the aspect of elasticity has been a concern of modern technologies and construction in recent centuries because of the advantages that expandable storage would bring to the fields of containment units with respect to population growth and space exploration. The world population is currently growing at an exponential rate, and as our population grows, the more important it will become to have containment units that can both contain large volumes of material as well as minuscule amounts of material without wasting space. In order accomplish this, we will need a new type of ...

Liquefied Natural Gas (Lng) As A Marine Fuel: Optimising The Associated Infrastructure In The Baltic Sea Region, Dimitrios Dalaklis Dd, Josefin Madjidian Jam, Aykut I. Ölçer Aio, Fabio Ballini Fb, Momoko Kitada Mk

Conference papers

International and national policies and regulations call for faster transition to sustainable energy production and use. Within the shipping industry one way forward is the use of LNG. Despite being of fossil origin LNG is considered to be an important step towards cleaner shipping given the better properties of the exhausts. The Go LNG initiative is focused on the development of demand and accessibility of LNG in the Baltic Sea Region (BSR). Activities associated with this strategic-in-nature project aim to promote the implementation of EU’s Clean Fuel Strategy and boost LNG usage through the whole transport chain. This paper ...

Utility Of Baroreflex Sensitivity As A Marker Of Stress, Amanda A. Anderson, Nir Keren, Andrew Lilja, Kevin Godby, Stephen B. Gilbert, Warren D. Franke

Warren D Franke

Presently, adaptive systems use various cognitive and cardiovascular measures to evaluate the functional state of the operator. One marker that has been largely ignored as an assessment tool is baroreflex sensitivity (BRS). This study examined the extent to which BRS changed in response to acute psychological and physical stressors. A total of 20 participants underwent 6-min exposures to a psychological stressor and a physical stressor. Baroreceptor sensitivity, blood pressure, heart rate, heart rate variability, stroke volume, cardiac output, mean blood pressure, total peripheral resistance, left ventricular ejection time, and pre-ejection period were continuously measured at rest and throughout the testing ...

Space Perception In Virtual Environments: Displacement From The Center Of Projection Causes Less Distortion Than Predicted By Cue-Based Models, Jonathan W. Kelly, Melissa Burton, Brice Pollock, Eduardo Rubio, Michael Curtis, Julio De La Cruz, Stephen B. Gilbert, Eliot H. Winer

Jonathan W. Kelly

Virtual reality systems commonly include both monocular and binocular depth cues, which have the potential to provide viewers with a realistic impression of spatial properties of the virtual environment. However, when multiple viewers share the same display, only one viewer typically receives the projectively correct images. All other viewers experience the same images despite displacement from the center of projection (CoP). Three experiments evaluated perceptual distortions caused by displacement from the CoP and compared those percepts to predictions of models based on monocular and binocular viewing geometry. Leftward and rightward displacement from the CoP caused virtual angles on the ground ...

Evaluation Boundary And Design Method For Insulating Packages, Liao Pan, Jun Wang, Lixin Lu

Journal of Applied Packaging Research

To evaluate the failure potential of insulated packaging to heat outside, a so-called evaluation boundary for insulating packages was proposed for designing and estimating insulating packages based on the heat transfer law between the environment and a packaged product through packaging. Three evaluation parameters were suggested for describing the failure mechanism of insulating packages. The validity of the presented evaluation boundary was verified by the experimental data. Finally, a new design method of insulating packages based on the boundary was proposed and an application example was performed as a demonstration. The results indicated that the three evaluation parameters (which are ...

Assessment Methods From Around The World Potentially Useful For Public Transport Projects, Eric Bruun, Marianne Vanderschuren

Journal of Public Transportation

The financial crisis in 2008/2009 has made many countries aware that public funds need to be managed better. A logical step is to identify methods that thoroughly assess the impacts of infrastructure and service investment. The authors argue that assessments should both identify and use performance indicators related to the ‘triple bottom line’, i.e. economic, social and environmental impacts.

This paper provides an overview of assessment methods used to evaluate public transport investments. Positive and negative aspects of various assessment tools are identified and discussed. Some developing world examples appear to be more elaborate and appropriate, than developed ...

Acoustic Tweets And Blogs: Using Social Media In An Undergraduate Acoustics Course, Lily M. Wang

Lily M Wang

Each fall, the author teaches an undergraduate architectural acoustics course to around 40 third-year architectural engineering students at the University of Nebraska. Beginning in 2011, a social media component was introduced to explore the use of this technology and how it may supplement the students' learning experience. Students were given an opportunity to receive extra credit by using Twitter and/or blogging about course material using a set hashtag (#AE3300) or through the course website. Results were positive, and the author will discuss pros and cons that she has experienced in adding this social media component. Suggestions for future implementations ...

Effects Of Reverberation And Noise On Speech Comprehension By Native And Non-Native English-Speaking Listeners, Z. Ellen Peng, Lily M. Wang, Siu-Kit Lau, Adam M. Steinbach

Lily M Wang

Previous studies have demonstrated the negative impact of adverse signal-to-noise-ratios on non-native English-speaking listeners' performance on speech recognition using recall tasks, as well as implied that comprehension skills were more impaired than recognition skills under reverberation and noise. The authors have themselves previously conducted a pilot study on three native and three non-native Englishspeaking listeners to examine the effects of reverberation and noise using speech comprehension tasks. Those results suggested that speech comprehension performance is worse under longer reverberation times (RT), and that a longer RT is more detrimental to speech comprehension by non-native listeners than native listeners. This paper ...

How Tonality And Loudness Of Noise Relate To Annoyance And Task Performance” Noise Control Eng. J. 65(2), 71-82., Joonhee Lee, Jennifer M. Francis, Lily M. Wang

Lily M Wang

Audible tones in noise generated by building mechanical equipment can be a leading cause of complaints from occupants. A number of metrics have been developed to quantify prominence of a tone, but previous work has shown that the impact of a certain tonality appears to vary with the level of the broadband noise signal. More work on how tonal signals of varying tonality, tone frequency and broadband noise levels relate to annoyance and task performance is needed. This paper investigates such relationships between current noise metrics, annoyance and task performance under assorted tonal noise conditions through subjective testing. Participants rated ...
