A Machine Learning Assessment System for Spoken English Based on Linear Predictive Coding

In the teaching of English, there is an increasing focus on practical communication skills. As a result, the speaking test component has received more and more attention from education experts. With the rapid development of modern computer technology and network technology, the use of computers to assess the quality of spoken English has become a hot topic of research in related fields at present. A machine learning assessment system based on linear predictive coding is proposed in order to achieve automatic scoring of spoken English tests. First, the principle of linear predictive coding and decoding is analyzed, and the traditional linear predictive coding and decoding algorithm is improved by using hybrid excitation instead of the traditional binary excitation. Second, the overall structure of the machine learning assessment system is designed, which mainly includes division into four modules: acoustic model acquisition module, speech recognition module, standard pronunciation transcription module, and decision module. Then, the speech recognition module is implemented by an improved linear predictive speech coding method to acquire the feature parameters of the speech signal and generate the speech feature vector. Finally, the convolutional neural network algorithm is used to train the speech features so as to implement the acoustic model acquisition module. The experimental results show that the improved linear predictive speech coding method yields more natural and higher intelligibility speech signals. The designed machine learning evaluation system is able to accurately detect information about the quality of the learner’s pronunciation.
12.6 dB squeezed light at 1550 nm from a bow-tie cavity for long-term high duty cycle operation

Squeezed states are an interesting class of quantum states that have numerous applications. This work presents the design, characterization, and operation of a bow-tie optical parametric amplifier (OPA) for squeezed vacuum generation. We report the high duty cycle operation and long-term stability of the system that makes it suitable for post-selection based continuous-variable quantum information protocols, cluster-state quantum computing, quantum metrology, and potentially gravitational wave detectors. Over a 50 hour continuous operation, the measured squeezing levels were greater than 10 dB with a duty cycle of 96.6%. Alternatively, in a different mode of operation, the squeezer can also operate 10 dB below the quantum noise limit over a 12 hour period with no relocks, with an average squeezing of 11.9 dB. We also measured a maximum squeezing level of 12.6 dB at 1550 nm. This represents one of the best reported squeezing results at 1550 nm to date for a bow-tie cavity. We discuss the design aspects of the experiment that contribute to the overall stability, reliability, and longevity of the OPA, along with the automated locking schemes and different modes of operation.

English Literature Students at Spanish University Have Positive Perceptions Towards but Limited Understanding of Online Resources

A Review of: Roig-Marín, A., &amp; Prieto, S. (2021). English literature students' perspectives on digital resources in a Spanish university. Journal of Academic Librarianship, 47(6). https://doi.org/10.1016/j.acalib.2021.102461 Abstract Objective – To assess students’ perception, use, and format preferences of library resources. Design – Online survey questionnaire. Setting – A public university in Spain. Subjects – 134 second-year, third-year, and fourth-year undergraduate English language and literature students. Methods – An anonymous survey was built using Google Forms and shared with eligible participants during March and April 2021. Survey participation was voluntary, although students were encouraged to respond and were provided with class time to do so. Nonetheless, due to the ongoing COVID-19 pandemic at the time of this study, courses were taught in a hybrid (both in-person and online) format and class attendance was not mandatory. The survey consisted of six multiple choice and four open-ended questions, and answers were required for all 10 questions. Main Results – Respondents were mostly satisfied with the available resources in supporting their studies in English literature and culture, with the majority preferring to access resources online (51%) or through both online and print formats (14%). Convenience was the most commonly cited reason for favoring online access, while improved processing and learning were mentioned by those preferring print. A majority of respondents also indicated they have used online resources from either their home university library (72%) or other libraries (55%). Conversely, 29% of the respondents were unable to identify any specific electronic resources. Conclusion – Study results indicate that Spanish undergraduate students majoring in English literature generally have a positive perception of library resources in supporting their studies and prefer online access over print. However, many of these students may also have an incorrect or limited understanding of how to differentiate between library resources, general websites, web search engines, or computer programs.

Conceptual Modeling of the Whole-Part Relationship

Conceptual models rely on structural information to describe relationships among UML classes; among these, the whole-part (WP) relationship plays a fundamental role. This paper explores and analyzes the WP semantics at large with a focus on its software engineering use. The WP relationship has often been treated as a first-class modeling construct in object-oriented analysis, a subject of keen interest and it is considered important for UML modeling. From the scientific and philosophical aspects, a theory of parts forming a whole is a complex issue, loaded with controversies that are widely discussed. This paper aims to offer a semantic assembly model that is useful to describe WP relationships in conceptual modeling. We contribute to the WP research by conducting an ontological analysis using UML samples that exemplify the WP construct. The method of investigation is based on a model called a thinging machine (TM) to explore the WP semantics through applying TM to numerous existing UML models. The TM model uses the so-called thimacs (things/machines) to form building blocks for describing the domain at a three levels of description: static, events, and behavioral models. This approach contrasts the UML method, which is infected by a multiplicity problem concerning the integrated view of structure and behavior and how to associate diagrams with one another. This investigation s results point to a promising contribution to the understanding of the notion of WP relationship in UML.
Phase Target-Based Calibration of Projector Radial Chromatic Aberration for Color Fringe 3D Measurement Systems

The camera and projector are indispensable hardware parts of a color fringe projection 3D measurement system. Chromatic aberration between different color channels of the projector and camera has an impact on the measurement accuracy of the color fringe projection 3D profile measurement. There are many studies on camera calibration, but the chromatic aberration of the projector remains a question deserving of further investigation. In view of the complex system architecture and theoretical derivation of the traditional projector radial chromatic aberration method, a phase target based on projector radial chromatic aberration measurement and the correction method are proposed in this paper. This method uses a liquid crystal display with a holographic projection film as the phase target. The liquid crystal display sequentially displays red, green, and blue horizontal and vertical sinusoidal fringe images. The projector projects red, green, and blue horizontal and vertical sinusoidal fringe images to the phase target in turn, and calculates the absolute phases of the display fringes and reflection fringes, respectively. Taking the green channel as the reference channel, a phase coordinate system is established based on the phases of the vertical and horizontal directions displayed on the display screen, using the phase of the reflection fringes on the display screen as the ideal phase value of the phase point. Then, the phase coordinate system of the red and blue channels is transferred to the green phase coordinate system to calculate the chromatic aberration of the red-green channels and the blue-green channels, and pre-compensation is conducted. Experimental results prove that this method can measure and calibrate the radial chromatic aberration of the projector without being affected by the image quality of the camera. The correction effect of this method is that the maximum chromatic aberration of the red-green channel decreases from 1.9591/pixel to 0.5759/pixel, and the average chromatic aberration decreases from 0.2555/pixel to 0.1865/pixel. In addition, blue-green channel maximum chromatic aberration decreased from 1.8906/pixel to 0.5938/pixel, and the average chromatic aberration decreased from 0.2347/pixel to 0.1907/pixel. This method can improve the projection quality for fringe projection 3D profile measurement technology.
COVID-19 Case Tracking System in Quarantine Policy: Focus on the Privacy Shift Concept and Application in South Korea

This study analyzed how Korea's quarantine policy manages personal information to prevent and control COVID-19. Korea effectively halted the spread of COVID-19 through epidemiological investigations and cell-broadcast systems. In this process, the route of infection is presented without identifying the patient, and the necessary participants are selected only through authentication. We found a correlation between the number of emergency text messages sent by the Ministry of Interior and Safety in 2020 and the number of confirmed cases (R2 = 0.465, p < 0.001). Based on Korea's case, we propose a new concept for solving the personal information problems that might arise during a pandemic response.
“Metrology is a key component of the industrial value-added chain”: an interview with Prof. Wolfgang Osten

Mendeleev said: "Science begins where one begins to measure," and "exact science is unthinkable without measure." During his more than 4-decades-long career, Prof. Wolfgang Osten has been devoted to optical metrology and inspection technologies. Osten and his research team developed the first automated system for the quantitative and qualitative evaluation of interferograms in the '80s, as well as the principle of tilted-wave interferometry for high-precision aspherical and free-form surface measurement. Both techniques have since been commercialized. His achievements have "lit the way" for research in optical metrology. The bond between Osten and Light Publishing Group can be traced back to 2012, when he first submitted a paper to Light: Science & Applications (LSA) as an author and published a paper1. Right after that, he was invited to join the Editorial Board for his enthusiasm. In 2019, he started the challenge of founding the new journal Light: Advanced Manufacturing (LAM) as the co-Editor-in-Chief. In this interview, Osten shared his insights on Optical Metrology, Holography, and the Founding of LAM with us. Follow the Q&As below and let us get closer to the "Holoknight".

Super-Apollonian circles and lattices of Gaussian integers

Abstract We study the circles of the Apollonian band circle super-packing, which are also the images of the real projective line by all linear fractional transformations of the group PLS (2 ,Z [ i ]) . This super-packing takes place on the torus rather than on the plane. We focus first on the connection between these circles and lattices in the ring of Gaussian integers. Then we explore the group structure of the set of such circles with given curvature. The end of this paper is more geometrically-minded and describes first a test to determine whether a Gaussian circle is Apollonian or not, then a process which yields quickly all Gaussian circles with curvature smaller than a given integer. We develop algorithms for each of the computational problems we encounter. MSC Classification: 11E25 , 11G99 , 20K01 , 52C26

Stakeholders’ Approach to Requirements Engineering and Management: A Conceptual Analysis

ABSTRACT The ever dynamic nature of business environment, global competition and increasing requests for more quality products by stakeholders have caused organizations to understand that the only way of survival in the market is to deliver better quality products to meet stakeholders’ needs. Many organizations, therefore, spend considerable amounts of their funds in activities related to improving products and services. This study in its qualitative nature employs a phenomenological approach to explore how requirements engineering can be successfully and sustainably attained through critical understanding of stakeholders’ needs, wants and preferences. The phenomenological approach provides an introductory background on the consequences of poor requirements engineering and management and why its importance cannot be over emphasized for twenty first century business organizations operating in an hyper competitive environment. The review of literature through desk research further provides insights on various definitions of conceptualization of requirements engineering and management. Stakeholder theory was adopted as the underpinning theory since stakeholders are the principal contributors and creators of requirements within the development of a product. The study concludes that stakeholders are the basis for requirements engineering. Hence, the study recommends involvement of stakeholders early on, to elicit desires, information and feedback from them, and to satisfy their information and communication needs. This is to ensure smooth development and efficient requirements engineering process. Keywords: Requirements, Engineering, Management, Stakeholder, Strategy, Products
