Multi-Period Liner Ship Fleet Planning With Dependent Uncertain Container Shipment Demand, Qiang Meng, Tingsong Wang, Shuaian Wang

Faculty of Engineering and Information Sciences - Papers

This paper deals with a realistic multi-period liner ship fleet planning problem by incorporating stochastic dependency of the random and period-dependent container shipment demand. This problem is formulated as a multi-period stochastic programming model with a sequence of interrelated two-stage stochastic programming (2SSP) problems characterized ship fleet planning in each single period. A solution method integrating dual decomposition and Lagrangian relaxation method is designed for solving the developed model. Numerical experiments are carried out to assess applicability and performance of the proposed model and solution algorithm. The results further demonstrate importance of stochastic dependence of the uncertain container shipment demand.

Application Of Problem Based Learning And Mastery Learning To Multimedia Education, Gabriel J. Grant, Dominick E. Fazarro, Luke Steinke

Online Journal for Workforce Education and Development

The current state of education and the workforce demands a special kind of learner capable of creativity, communicating effectively, analytical skill application, critical thinking, and problem solving. Whereas these skills are important, it is also a necessity for learners to be masters of the knowledge and skills that they have acquired. Traditional educational methods have proven to be somewhat ineffective in producing these results. Problem based learning has proven worthy in handling some of the load, however, mastery learning has been abandoned long ago for reasons in spite of its effectiveness. Through given examples and careful design, the educator will ...

Safety Culture Perceptions In A Collegiate Aviation Program: A Systematic Assessment, Daniel Kwasi Adjekum

Journal of Aviation Technology and Engineering

An assessment of the perceptions of respondents on the safety culture at an accredited Part 141 four year collegiate aviation program was conducted as part of the implementation of a safety management system (SMS). The Collegiate Aviation Program Safety Culture Assessment Survey (CAPSCAS), which was modified and revalidated from the existing Commercial Aviation Safety Survey (CASS), was used. Participants were drawn from flight students and certified flight instructors in the program. The survey captured the perceptions of participants on the status of the safety culture in the program. There were significant variances in the perception of respondents on the safety ...

Mining Contrast Subspaces, Lei Duan, Guanting Tang, Jian Pei, James Bailey, Guozhu Dong, Akiko Campbell, Changjie Tang

Kno.e.sis Publications

In this paper, we tackle a novel problem of mining contrast subspaces. Given a set of multidimensional objects in two classes C  +  and C  − and a query object o, we want to find top-ksubspaces S that maximize the ratio of likelihood of o in C  +  against that in C  −. We demonstrate that this problem has important applications, and at the same time, is very challenging. It even does not allow polynomial time approximation. We present CSMiner, a mining method with various pruning techniques. CSMiner is substantially faster than the baseline method. Our experimental results on real data sets ...

State Of The U.S. Ocean And Coastal Economies 2014, Judith T. Kildow, Charles S. Colgan, Jason D. Scorse, Pat Johnston, Matt Nichols

Publications

The nation's coasts and oceans contribute much to the United States economy. For the past 14 years, the National Ocean Economics Program (NOEP), now a program of the Center for the Blue Economy at the Monterey Institute of International Studies, has compiled time-series data that track economic activities, demographics, ports and cargo volume and value, natural resource production and value, non-market values, and federal expenditures in the U.S. coastal zone both on land and in the water. A report on the ocean and coastal economies of the United States was released by NOEP in 2009 covering data through ...

Ship Space And Database: The Co-Shaping Of Spatial Configurations Aboard Ocean Drilling Cruise Ships And Material Artifacts Of Practice In Onshore Laboratories, Peter Darch

Peter Darch

This paper presents a longitudinal ethnographic study of a large, multidisciplinary scientific project studying subseafloor microbial life.

To study this life, scientists need rock and water samples taken from the seafloor. To collect these samples, scientists participate in ocean drilling cruises, such as those carried out as part of the International Ocean Discovery Program (IODP). The IODP and its forerunners have been operating since the 1960s. Initially, these cruises only involved physical scientists (such as geochemists). In recent years, microbiologists have become part of these cruises. This has involved reallocating space on cruise ships to the construction of a microbiology ...

Is There A Clubbing Effect Underlying Chinese Research Citation Increases?, Li Tang, Philip Shapira, Jan Youtie

Philip Shapira

There is increasing evidence that citations to Chinese research are rising sharply. A variety of explanations have been explored in previous studies. This research aims to explore another potential explanation – whether there exists a “clubbing” effect in China’s surge in research citations, in which a higher rate of internal citing takes place among Chinese most influential researchers. Focusing on the most highly cited research articles in nanotechnology, we found that a larger proportion of Chinese nanotechnology research citations are localized within individual, institutional and national boundaries. Both descriptive and statistical tests suggest that highly cited Chinese papers are more ...

Where’S The Rhetoric? Broader Impacts In Collaborative Research, Leah Ceccarelli

Poroi

Rhetoricians involved in funded collaborative research with scientists have discussed some of their own rhetorical choices in conveying to their research partners the unique and valuable contributions made by rhetorical inquiry. But different definitions of what expertise is offered by someone trained in rhetoric as a field of study shape their conclusions, as does the fact that most are in the early stages of this collaborative work. They have provided an energetic start to what promises to be a spirited, valuable, and lengthy conversation about how rhetoricians of science might think about the broader impacts of their research.

With Whom Do We Speak? Building Transdisciplinary Collaborations In Rhetoric Of Science, Caroline Gottschalk Druschke

Poroi

There is a necessary and growing preoccupation in rhetoric of science with the real-world consequences of our work and with the mediating role rhetoric should play at the nexus of science-publics-policy. Emerging from these discussions are calls by Gross, Ceccarelli, and Herndl for thoughtful and practical action. This paper builds from this preoccupation with thoughtful praxis, highlighting three funded collaborations that offer a vision for engaged, mutually beneficial, consequential collaborations in rhetoric of science. Taken together, these collaborations constitute an argument for Herndl’s “applied rhetoric of science.” They move beyond transactional models of collaboration and posit a transdisciplinary vision ...

Usos E Significados Da Tecnologia Na Academia, João Monteiro Matos

João Monteiro Matos

This study seeks to understand how the academic population – professors and researchers perceives, uses, and interacts with new information and communication technologies (ICT) in their everyday working practices. The main goal is to understand whether these new technologies can be an indicator of different scientific cultures, using the metaphor of the “two cultures” introduced by Charles Snow (1963).

I make use of this metaphor to examine differences and specificities of two scientific communities: the natural sciences and the social sciences community at two institutions of the University of Lisbon.

This research follows a mixed methods strategy, combining the application of ...

Unpacking The Matthew Effect In Citations, Jian Wang

Jian Wang

One problem confronting the use of citation-based metrics in science studies and research evaluations is the Matthew effect. This paper reviews the role of citations in science and decomposes the Matthew effect in citations into three components: networking, prestige, and appropriateness. The networking and prestige effects challenge the validity of citation-based metrics, but the appropriateness effect does not. Using panel data of 1,279 solo-authored papers’ citation histories and fixed effects models, we test these three effects controlling for unobserved paper characteristics. We find no evidence of retroactive networking effect and only weak evidence of prestige effect (very small and ...

Dem Simulation Of The Behaviour Of Geogrid Stabilised Ballast Fouled With Coal, Ngoc Trung Ngo, Buddhima Indraratna, Cholachat Rujikiatkamjorn

Faculty of Engineering and Information Sciences - Papers

Geogrids are commonly used in railway construction for reinforcement and stabilisation. When railway ballast becomes fouled due to ballast breakage, infiltration of coal fines, dust and subgrade soil pumping, the reinforcement effect of geogrids decreases significantly. This paper presents results obtained from Discrete Element Method (DEM) to study the interface behaviour of coal-fouled ballast reinforced by geogrid subjected to direct shear testing. In this study, irregularly-shaped aggregates (ballast) were modelled by clumping together 10-20 spheres in appropriate sizes and positions. The geogrid was modelled by bonding a large number of small spheres together to form the desired grid geometry and ...

The Path Space Of A Directed Graph, Samuel B. G Webster

Faculty of Engineering and Information Sciences - Papers

We construct a locally compact Hausdorff topology on the path space of a directed graph E and identify its boundary-path space ∂E as the spectrum of a commutative C*-subalgebra DE of C*(E). We then show that ∂E is homeomorphic to a subset of the infinite-path space of any desingularisation F of E. Drinen and Tomforde showed that we can realise C*(E) as a full corner of C*(F), and we deduce that DE is isomorphic to a corner of DF. Lastly, we show that this isomorphism implements the homeomorphism between the boundary-path spaces.

Smart Home Electricity Management In The Context Of Local Power Resources And Smart Grid, Weiliang Zhao, Lan Ding, Paul Cooper, Pascal Perez

Faculty of Engineering and Information Sciences - Papers

This work proposes a smart home electricity management approach that can predict and schedule electricity demand and supply by considering: the 'state' of the smart grid, local power generation capacity, and electrical consumption of household appliances. The prediction of weather conditions and the immediate and longer-term plans of the residential home occupants are crucial parameters in the smart home decision-making system that acts on behalf of the occupants. This paper provides a motivation example and associated scenarios, electrical energy supply/demand models, formalization of the cost optimization problem, and scheduling schemes for a smart home electricity management system in the ...

On The Security Of Auditing Mechanisms For Secure Cloud Storage, Yong Yu, Lei Niu, Guomin Yang, Yi Mu, Willy Susilo

Faculty of Engineering and Information Sciences - Papers

Cloud computing is a novel computing model that enables convenient and on-demand access to a shared pool of configurable computing resources. Auditing services are highly essential to make sure that the data is correctly hosted in the cloud. In this paper, we investigate the active adversary attacks in three auditing mechanisms for shared data in the cloud, including two identity privacy-preserving auditing mechanisms called Oruta and Knox, and a distributed storage integrity auditing mechanism. We show that these schemes become insecure when active adversaries are involved in the cloud storage. Specifically, an active adversary can arbitrarily alter the cloud data ...
