Speech synthesis systems are now getting smarter and more natural thanks to the power of deep neural networks. However, each language has a different phonological and contextual characteristics, we have conducted experiments, statistics, and applied Vietnamese phonetics to improve speech synthesis systems based on Tacotron2 neural networks. Our methods achieve the accuracy of 97% in text normalization task, and the synthesized speeches with a MOS score of 3.97, asymptotic to 4.43 of the voices that are directly recorded. We also provide a library for standardizing Vietnamese text called Vinorm and a package that converts text into a phonetic format called Viphoneme, which is used as an input for end-to-end neural networks, make the synthesis process faster, more intelligent and natural than using character inputs. © 2020 IEEE.

For dealing with traffic bottlenecks at airports, aircraft object detection is insufficient. Every airport generally has a variety of planes with various physical and technological requirements as well as diverse service requirements. Detecting the presence of new planes will not address all traffic congestion issues. Identifying the type of airplane, on the other hand, will entirely fix the problem because it will offer important information about the plane's technical specifications (i.e., the time it needs to be served and its appropriate place in the airport). Several studies have provided various contributions to address airport traffic jams;however, their ultimate goal was to determine the existence of airplane objects. This paper provides a practical approach to identify the type of airplane in airports depending on the results provided by the airplane detection process using mask region convolution neural network. The key feature employed to identify the type of airplane is the surface area calculated based on the results of airplane detection. The surface area is used to assess the estimated cabin length which is considered as an additional key feature for identifying the airplane type. The length of any detected plane may be calculated by measuring the distance between the detected plane's two furthest points. The suggested approach's performance is assessed using average accuracies and a confusion matrix. The findings show that this method is dependable. This method will greatly aid in the management of airport traffic congestion. Copyright © 2021, The Authors. All rights reserved.

Mederer, Helen Pasquerella, Lynn Peckham, Joan River-Hudec, Mercedes Wishner, Karen University of Rhode Island United States Department of Psychology NSF ADVANCE Grant Program United States Department of Sociology Department of Sociology and Anthropology ADVANCE Leadership Team URI President's Commission on the Status of Women Switzerland Work/Life Committee URI Switzerland Institutional Review Board University of Rhode Island United States John Hazen White Sr. Center for Ethics and Public Service United States Department of Computer Science University of Rhode Island United States Department of Chemical Engineering Department of Oceanography University of Rhode Island United States

In 2000, University of Rhode Island (URI) President Carothers acknowledged, following an extended and sometimes acrimonious AAUP faculty union grievance process, that there had been a climate hostile to women faculty in the College of Engineering. The purpose of this paper is to describe the positive steps that were taken at URI subsequent to that grievance to improve the climate for women faculty in STEM (science, Technology, Engineering and Math) fields, and to place these steps within a framework for climate change. The paper starts with an overview of the percentages of women nationally in Engineering, followed by a description of the hostile grievance process that took place at URI. Next is a discussion of pro-active measures that were taken by many communities of faculty on the URI campus, including most recently, those of the advance grant funded by the National science Foundation. These measures have been guided by a grounded theory approach to climate change that posits simultaneous change in individuals, interactional contexts, and institutional practices. As a result, URI has recruited a significant percentage of new women faculty in STEM fields in a relatively short time, and is working hard to ensure that they are retained. There have been many recent national initiatives to address the problem of the under representation of women in the science, technology, engineering, and math (STEM) disciplines. It is well recognized that, beyond workplace equity, diversifying the practitioners in Engineering and other STEM fields will enrich these disciplines by bringing different perspectives, skills, and values to the fore, will help America remain globally competitive, and will more responsibly integrate Engineering practice with societal needs. Importantly, women and minority faculty also provide critically needed role models needed to attract and retain a more diverse student population. In Engineering, women comprise only about 20% of bachelor degree recipien

A system of linear constraints is represented as a set of half-planes S = {(a j X + b j Y + c j ≤ 0) j = 1...N}. Therefore, in the context of linear constraints two terms “set” and “system” can be used interchangeably whenever one of two is suitable. A set of linear constraints represents a convex polygon that is the intersection of all half-planes in the set. The convex polygon represented by S is called the feasible polygon of S. Such sets of linear constraints can be used as a new way of represent spatial data. These sets need to be manipulated efficiently and stored using minimal storage. It is natural to store only sets of linear constraints which are feasible and in irredundant format. Therefore, it is very important to find out if a given system is feasible and/or bounded and to find the minimal (irredundant) set of linear constraint which have the same feasible area with the given one. LASSEZ and MAHER (1988) have investigated algorithms to check if a system of linear constraints over multidimensional R d is feasible. LASSEZ et al (1989) have investigated algorithms to eliminate redundant constraints from a system of linear constraints over R d . Their algorithms are based on the Fourier variable elimination (similar with Gaussian elimination in solving the linear system of equations) and therefore have the running time O(N 2) where N is the number of constraints, and as such it is not efficient. DYER (1984) and MEGIDDO (1983) have independent proposed linear time algorithms to solve the linear programming problem in 2- and 3-dimension cases.

The paper will describe the streamlined acquisition process involved in the procurement, and conversion, of the first two of three Enhanced Maritime Prepositioning Force (MPF(E)) ships. This program was one of the first programs undertaken within the Government's new policy of Acquisition Reform, which resulted in the development of "performance based" requirements for these ships. This program is notable in that one prime contractor is responsible for the accomplishment of all phases, and that the contractors participating were not shipyards as is usually the fashion for Government ship acquisition programs. Also of note, was that after the conversion contracts were awarded, responsibility for the conduct of detail design, conversion, and operation and maintenance of the ship was transferred from the NAVSEA Sealift program Office (PMS 385) to the Military Sealift Command (MSC). The first part of the paper will describe the basic mission of the MPF(E) ships, and a description of the origin of the program requirements. The second part of the paper will chronicle in detail the portions of the engineering design and specification development process, which will include descriptions of the unique digital data recording and tracking systems developed by the Government MPF(E) Design Support Team to support the acquisition phases of the procurement. The third and final part of the paper will elaborate on the conversion contract awards and the transition of the program from PMS 385 to MSC.

Identification and Validation of a New Nursing Diagnosis: Sick Role Conflict

引用

International Journal of Nursing Terminologies and Classifications 1992年第4期3卷 141-147页

作者： Kubsch, Sylvia M. Wichowski, Harriet Conley Dr. Kubsch fosters the use of nursing diagnosis in hospitals and nursing homes through her students her work as a consultant and as a provider of continuing education workshops on nursing process. Currently she is pioneering an effort to advance the use of independent nursing interventions in curriculums and in clinical practices as the natural continuation of nursing diagnoses. Her recent research efforts have focused on theory building which proposes several factors that influence the use of independent nursing interventions. Dr. Wichowski has taught psychiatric nursing and fundamentals of nursing in four collegiate programs. For die past 8 years she has been employed as a teacher in a professional nursing program for registered nurses seeking a Bachelor of Science in Nursing degree. She is co-author of four publications that demonstrate the application of computer techniques to aid in the solution of various health problems.

The purpose of this research is to assess the presence, etiology, and effects of sick role conflict experienced by hospitalized patients. Data from 99 hospitalized adult subjects were analyzed using a path analysis design. Patients were interviewed at the bedside using a structured interview tool developed by the researchers. It was found that subjects who occupied multiple roles, who were not adequately prepared for hospitalization, and who had an acute rather than chronic illness were prone to experience sick role conflict when hospitalized. Those subjects experiencing sick role conflict did not fully assume the sick role as defined by Parsons (1956). As a consequence of incomplete sick role assumption, an increased incidence of human responses such as guilt, powerless ness, anxiety, decreased self‐esteem, depression, appetite change, and insomnia were reported. The researchers urge nurses to assume responsibility for diagnosing and treating sick role conflict, a human response lo hospitalization commonly seen among patients.

A ship design methodology is presented for developing hull forms that attain improved performance in both seakeeping and resistance. Contrary to traditional practice, the methodology starts with developing a seakeeping-optimized hull form without making concessions to other performance considerations, such as resistance. The seakeeping-optimized hull is then modified to improve other performance characteristics without degrading the seakeeping. Presented is a point-design example produced by this methodology. Merits of the methodology and the point design are assessed on the basis of theoretical calculations and model experiments. This methodology is an integral part of the Hull Form Design System (HFDS) being developed for computer-supported naval ship design. The modularized character of HFDS and its application to hull form development are discussed.
