When discussing self-driving cars, they have some fantastic and encouraging benefits and ideas. Some ideas would be that vehicles could communicate with each other, we could eliminate the need for traffic lights, and …

What Is Nonclassical About Uncertainty Relations?, Lorenzo Catani, Matthew S. Leifer, Giovanni Scala, David Schmid, Robert W. Spekkens

Mathematics, Physics, and Computer Science Faculty Articles and Research

Uncertainty relations express limits on the extent to which the outcomes of distinct measurements on a single state can be made jointly predictable. The existence of nontrivial uncertainty relations in quantum theory is generally considered to be a way in which it entails a departure from the classical worldview. However, this perspective is undermined by the fact that there exist operational theories which exhibit nontrivial uncertainty relations but which are consistent with the classical worldview insofar as they admit of a generalized-noncontextual ontological model. This prompts the question of what aspects of uncertainty relations, if any, cannot be realized in …

“Arsip Kacau”: How Messy Records Are Perceived By Indonesians In The Context Of Document Disease, Suprayitno Suprayitno, Rahmi Rahmi, Dian Novita Fitriani

Proceedings from the Document Academy

This paper examines how the Indonesian people perceive and construct arsip kacau (messy records). Messy records as documents seem to have the power to make humans psychologically ill by becoming uneasy, discomfort, stressed, burnout, and uncomfortable, all of which are diseases. This is similar to documentality introduced by Frohmann that documents can enable, produce, encourage, permit, and influence a person to experience document disease. This paper uses a qualitative approach with data collection in the form of literature and surveys from Indonesian people. The perception of archivists and the general public in Indonesia concerning the cause of the “messy records” …

Artificial Intelligence And The Preservation Of Historic Documents, Gaute Barlindhaug

Proceedings from the Document Academy

In recent decades, digitization has been presented as an important strategy both for the preservation of historic documents and for giving increased access for researchers to such materials. In the Norwegian context, this has not only implied the digitization of printed matter but also the digitization of audiovisual material like photography and analog tape recordings. From a technical perspective, there are of cause difficulties in digitizing such a variety of material when considering the diversity of media formats dating back to the nineteenth century. However, from the archival community criticism has been raised not only about the quality of the …

Be Our Guest Or Welcome Foolish Mortals? Disney’S Invitation To Play And The Delusion/Illusion Of Hyperreal, Immersive Documents, L.P. Coladangelo

Proceedings from the Document Academy

This paper playfully appropriates the metaphor of delusional states to frame a discussion of hyperreal documents present in Disney theme parks and resorts. A brief overview of the literature on delusion in individuals transitions into the collective formation of positive illusions to introduce the concept of play. The conceptual framework of play culture, or ludics, is presented to understand cultural production and meaning, which is further described in relation to theme park design and the negotiation of theme park experiences. This discussion is situated in document theory to explicate the intentionality of theme park designers and the indexicality of park …

Performance Analysis: Using The Northern Sea Route As An Alternative To Traditional Routes, Liangkun Xu, Qing Yu

Journal of Marine Science and Technology–Taiwan

The grounding accident of M/V EVER GIVEN in the Suez Canal causes a catastrophic loss on shipping companies. Alternatively, previous studies have presented encouraging findings of the remarkable benefits of time and cost saving in the Northern sea route (NSR) due to extend the ice-free time and shorten the distance. Ships using the NSR could shorten as much as 40% of the sailing distance from China (Shanghai) to Europe (Rotterdam) compared with the traditional route via the Suez Canal. This paper investigates the economic potential of using the NSR as a cost-effective route in comparison with Suez Canal Route (SCR) …

Numerical And Approximate Analytic Solutions Of Second- Order Nonlinear Boundary Value Problems, Chein-Shan Liu, Jian-Hung Shen, Yung-Wei Chen

Journal of Marine Science and Technology–Taiwan

The shooting method consists of guessing unknown initial values, transforming a second-order nonlinear boundary value problem (BVP) to an initial value problem and integrating it to obtain the values at the right end to match the specified boundary condition, which acts as a target equation. In the shooting method, the key issue is accurately solving the target equation to obtain highly precise initial values. Due to the implicit and nonlinear property, we develop a generalized derivative-free Newton method (GDFNM) to solve the target equation, which offers very accurate initial values. Numerical examples are examined to show that the shooting method …

Optimization Of Circular Silencers Internally Hybridized With Multiple Reverse Chambers Using The Ga Method, Min-Chie Chiu, Ying-Chun Chang, Tian-Syung Lan, Ho-Sheng Chen

Journal of Marine Science and Technology–Taiwan

A noise abatement method using an eigen function in conjunction with an optimizer (Genetic Algorithm) under a space-constrain situation is proposed in this study concerning a high order wave propagation effect. An eigen function is used to describe an acoustical field and shorten the acoustical model in a four-pole transfer matrix form. The system’s four-pole matrix estimates the Transmission Loss (TL) for the silencers by multiplying individual four-pole matrices.

Additionally, a case study of an air compressor’s broadband noise elimination is introduced. Three types of circular reverse silencers (silencers A-C) internally hybridized with multiple straight chambers are adopted to efficiently …

Journal of Marine Science and Technology–Taiwan

The aim of this study was to identify the sources of uncertainties of typhoon wave field monitoring using HF radar and to quantitatively assess the bias of the wave parameters, such as significant wave height and mean period, retrieved under various conditions. The strategy was to apply a purely numerical simulation of the Doppler-range spectra and then compare the estimation results to the target. For the quantitative investigation, a numerical test-bed was established. The test-bed was used to simulate the Doppler spectra based on Barrick’s (1972) theory by using the input of the directional wave spectra. The typhoon wave spectra …

A Fused Data Based Real-Time Collision Warning System For Ferries In The Yangtze River, Xiaojia Liu, Ke Zhang, Han Xue, Yingtang Li

Journal of Marine Science and Technology–Taiwan

The risks for ferries in the Yangtze River are relatively high, as they frequently cross the main traffic flows, leading to more intersections with other upwards and downwards ships. Although some studies have developed many models to assess collision risks in the Yangtze River, collision warning studies on ferries are scant. Meanwhile, most of the current collision studies evaluate risk based on AIS data, which are incapable of providing real-time ship information as they are discrete-time series data. In this work, fused data combining radar and AIS data are applied in a real-time ship collision warning model to assess the …

Experimental Study Of The Effect Of A Solid Wing Conveyor On Marine Debris Collection, Erik Sugianto, Jeng-Horng Chen

Journal of Marine Science and Technology–Taiwan

Marine debris is a global problem that has not been resolved. This has encouraged the emergence of marine debris cleaning technologies, one of which is a conveyor ship. However, how effective conveyors are in collecting waste has not been studied. In this paper, experimental research on conveyors as marine debris collectors is investigated. The capability of catamarans with or without solid wing conveyors to collect marine debris is explored. Three kinds of marine debris collection models are used: no-wing conveyor, a 12.5-cm-long wing conveyor, and an 18.75-cm-long wing conveyor. Artificial marine debris (AMD) is spread on the water surface in …

Solving Nonlinear Boundary Value Problems With Nonlinear Integral Boundary Conditions By Local And Nonlocal Boundary Shape Functions Methods, Chein-Shan Liu, Yung-Wei Chen, Jian-Hung Shen

Journal of Marine Science and Technology–Taiwan

The paper considers the second-order nonlinear boundary value problem (NBVP), which is equipped with nonlinear integral boundary conditions (BCs). Two novel iterative algorithms are developed to overcome the difficulty of NBVP with double nonlinearities involved. In the first iterative algorithm, two nonlocal shape functions incorporating the linear integral terms are derived, and a nonlocal boundary shape function (NBSF) is formulated to assist the solution. Let the solution be the NBSF so that the NBVP can be exactly transformed into an initial value problem. The new variable is a free function in the NBSF, and its initial values are given. For …

The Impact Of A Five-Day Number Sense Intervention On High School Student's Quantitative Reasoning Skills And Self-Efficacy, Rebecca Steele-Mackey

Dissertations

Understanding numerical quantities and applying this knowledge in practical applications is essential throughout life. A well-developed number sense comes from learning foundational skills and continuing to rely on these skills and concepts in higher mathematical education as well as in adulthood. Prior research shows that K-8 students lack a conceptual understanding of fraction, decimal, and percentage concepts (NCTM, 2009). While there is literature that identifies a deficit in these mathematical areas, there is a need to examine possible activities and interventions that can be performed throughout secondary education courses that support growth in students' conceptual understanding of rational number concepts. …

An Asset Model: Identifying Institutional Characteristics And Behaviors That Close Community College Completion Gaps Between Black And White Students, Courtney Lange

Dissertations

The United States fails to meet its own workforce needs, and estimates show that by the year 2025, almost two out of three jobs in the nation will require at least some postsecondary education or training (Carnevale et al., 2019b). Jobs with the fastest growth rate will require an associate degree (Carnevale et al., 2019b). According to the most recent national data from the National Student Clearinghouse (NSC) Research Center, one in three students begin their college journey at a community college (NCES, 2019). Only 40% finish a degree or credential within six years (NCES, 2019). The proportion of those …

Psychological Capital And Perceived Employability: Exploring Women Veterans’ Military-To-Civilian Career Transition, Tundra Gatewood

Dissertations

The veteran human capital remains integral to the U.S. workforce and sustainment of its competitive advantage (Carter, Schafer, et al., 2017). Women constitute 17% of 1.4 million servicemembers and 10% of 18.4 million veterans, with a projected population growth of 18% by 2040 (Defense Manpower Data Center [DMDC], 2021; U.S. Bureau of Labor Statistics, 2020a). Each year, an estimated 30,000 ex-servicewomen enter the national labor force (National Center for Veterans Analysis and Statistics, 2019; U.S. Bureau of Labor Statistics, 2020a). Most of these ex-servicemembers turned veterans must navigate the military-civilian divide and negotiate their economic worth in highly divergent and …

Policy Implications Of Managing Biodiversity And Natural Resources Across International Boundaries, Dillon Brown

Dissertations

Fisheries Management under the best of scenarios is a complex action. It requires thoughtful consideration of resources that tend to be out of sight, widely distributed, highly variable both spatially and temporally, and present dramatic variation in life history and ecology. No one management approach has been developed which can effectively incorporate all these variables. Add to this the issue of transnational boundary movements of these resources, and one discovers that this complex issue needs to be addressed by multiple entities, agencies, and nations to have any chance of success.

This research set out to discover ways in which fisheries …

Estimation Of Cotton Canopy Parameters Based On Unmanned Aerial Vehicle (Uav) Oblique Photography, Jinyong Wu, Sheng Wen, Yubin Lan, Xuanchun Yin, Jiantao Zhang, Yufeng Ge

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Background: The technology of cotton defoliation is essential for mechanical cotton harvesting. Agricultural unmanned aerial vehicle (UAV) spraying has the advantages of low cost, high efficiency and no mechanical damage to cotton and has been favored and widely used by cotton planters in China. However, there are also some problems of low cotton defoliation rates and high impurity rates caused by unclear spraying amounts of cotton defoliants. The chemical rate recommendation and application should be based upon crop canopy volume rather than on land area. Plant height and leaf area index (LAI) is directly connected to plant canopy structure. …

The Effects Of Poor Maternal Nutrition In Ewes On The Growth And Development Of Offspring, Zoey Weisman

Honors Scholar Theses

Maternal nutrition is the diet that a mother intakes from before pregnancy through the end of lactation (Martin, 2018). Pregnant ruminants that are raised in pastures are frequently subject to undernutrition due to changes in the quantity and quality of available forage, which results in detrimental effects on the development of muscle and adipose tissues of offspring that can persist into adulthood (Hoffman, 2014). The quality of animal feed varies due to weather changes and climate fluctuations. Sheep usually gestate during the winter, as they are short-day breeders, and during this time, the forage consumed is limited and usually of …
