Abstract:
A generalized approach to fast interpretation of objects and their features has so far eluded researchers. In manufacturing, this interpretation can be approached from the vision point of view or from the CAD data perspective. Presently, CAD systems are widely used in several aspects of manufacturing production. It is therefore more efficient to use CAD data for object reasoning in manufacturing, especially when systems will eventually be data driven. Components can be modelled on a CAD system using various modelling techniques and the representation of their geometric information is still CAD system dependent. However, the advent of the Initial Graphics Exchange Specification (IGES) now makes it possible to represent CAD data in a neutral and standard manner.This paper describes a scheme for recognizing and representing features for CAD data extracted using the IGES interface. The concepts developed are based on graph-based feature representation, where features are represented by a set of faces as well as their topological adjacency.Strategies for classifying features and methods of decomposing a complicated feature into several simpler features for recognition purposes are discussed.

Abstract:
The development and application of computer-aided design (CAD) technology has led to rapid improvements in product design automation, crafting process automation and numerical control programming automation. Machining feature refers to basic configuration units that constitute part shapes and the collection of non-geometric information with engineering semantics attached to it. The integration of mechanical numerical control parts is the integration of part design features and machining features, and each feature corresponds to a set of processing methods. Based on the summaries and analyses of previous research works, this paper expounded the current status and significance of mechanical numerical control board part integration, elaborated the development background, current status and future challenges of machining features and CAD technology, introduced a data transfer method of CAD integration and machining features-based part integration system, analyzed the design and machining features of CAD integration of board parts, constructed the graphics processing model and information reorganization model for CAD integration of board parts; conducted the feature description and modeling analysis of CAD integration of plate parts; discussed the crafting information similarity of mechanical numerical control plate part integration; explored the feature information and expression of feature library for plate parts integration.

Abstract:
It is becoming increasingly common for manufacturing design teams to be composed of members belonging to the same organization, yet located in geographically different places. This has significantly increased the need for better support of synchronous communication among team members collaborating over a design. Unfortunately, there is a considerable technological gap in the support for collaborative, synchronously communicating mechanical CAD systems. In this paper we describe a prototype system, CoCAD, that provides a number of features that support synchronous collaboration among a number of mechanical CAD engineers located at different sites. Some of these features include the ability for each person to edit a design, the ability for each user to customize their local view of a design, the ability for each user to share a common view of a design, a shared pointer, the ability for someone to join in the middle of a design session, and object ownership and access permissions.

Abstract:
Heart sound signals reflect valuable information about heart condition. Previous studies have suggested that the information contained in single-channel heart sound signals can be used to detect coronary artery disease (CAD). But accuracy based on single-channel heart sound signal is not satisfactory. This paper proposed a method based on multi-domain feature fusion of multi-channel heart sound signals, in which entropy features and cross entropy features are also included. A total of 36 subjects enrolled in the data collection, including 21 CAD patients and 15 non-CAD subjects. For each subject, five-channel heart sound signals were recorded synchronously for 5 min. After data segmentation and quality evaluation, 553 samples were left in the CAD group and 438 samples in the non-CAD group. The time-domain, frequency-domain, entropy, and cross entropy features were extracted. After feature selection, the optimal feature set was fed into the support vector machine for classification. The results showed that from single-channel to multi-channel, the classification accuracy has increased from 78.75% to 86.70%. After adding entropy features and cross entropy features, the classification accuracy continued to increase to 90.92%. The study indicated that the method based on multi-domain feature fusion of multi-channel heart sound signals could provide more information for CAD detection, and entropy features and cross entropy features played an important role in it.

Abstract:
In this study, we analyze nonlinear feature extraction methods in terms of their ability to support the diagnosis of coronary artery disease (CAD) and myocardial infarction (MI). The nonlinear features were extracted from electrocardiogram (ECG) signals that were measured from CAD patients, MI patients as well as normal controls. We tested 34 recurrence quantification analysis (RQA) features, 14 bispectrum, and 136 cumulant features. The features were extracted from 10,546 normal, 41,545 CAD, and 40,182 MI heart beats. The feature quality was assessed with Student’s [Formula: see text]-test and the [Formula: see text]-value was used for feature ranking. We found that nonlinear features can effectively represent the physiological realities of the human heart.

Abstract:
There are many different programs that can perform Computer Aided Design (CAD). In order for these programs to share data, file translations need to occur. These translations have typically been done by IGES and STEP files. With the work done at the BYU CAD Lab to create a multi-engineer synchronous heterogeneous CAD environment, these translation processes have become synchronous by using a server and a database to manage the data. However, this system stores part data in a database. The data in the database cannot be used in traditional Product Lifecycle Management systems. In order to remedy this, a new database was developed that enables every edit made in a CAD part across multiple CAD systems to be stored as well as worked on simultaneously. This allows users to access every action performed in a part. Branching was introduced to the database which allows users to work on multiple configurations of a part simultaneously and reduces file save sizes for different configurations by 98.6% compared to those created by traditional CAD systems.

Resumo: A utilização de recursos assistidos por computadores como sistemas CAD/CAM e máquinas CNC tem se tomado bastante acentuada no ambiente industrial, propiciando uma série de vantagens aos seus usuários. Em contrapartida, essa utilização também pode incorrer em problemas, como o surgimento de pontos isolados com alto índice de eficiência local, mas que não agregam valor às operações das empresas, principalmente em função da dificuldade de integrar as informações que são geradas e compartilhadas pelas áreas de manufatura. Este trabalho apresenta um modelo conceitual, orientado às necessidades de um fabricante hipotético de máquinas e equipamentos sob encomenda, como uma das formas de melhorar a integração das informações geradas durante a fase de Projeto e que são compartilhadas com outras áreas vinculadas à Manufatura do produto, permitindo a formação de um Banco de Dados comum. Tal modelo utiliza os conceitos de Tecnologia de Grupo e Projeto baseado em Features, sendo que um aplicativo para modelamento CAD (2D) foi desenvolvido para demonstrar sua utilização. A simulação dos resultados obtidos permite verificar a possibilidade de obtenção de melhorias na integração das informações compartilhadas, redução de atividades que não agregam valor ao produto e menor dependência da experiência e intervenção humana para realização de algumas atividades
Abstract: The use of Computer Aided systems such as CAD/CAM and NC machines have been established in the industrial environment as standard because of their ability to increase productivity and quality. But such systems can also be a source of problems if there is not enough attention for the integration of the informations that are shared by the manufacturing areas, which will lead to the growth of"automation islands". This paper presents a conceptual model, oriented to the needs of a hypothetical machine manufacturer, as a method to improve the integration of Design and Manufacturing data and to allow for a common data base formation. This model uses concepts from Group Technology (GT) and Feature-based Modeling methodologies. A sofiware was developed to design 2D rotational parts in a CAD system environment. Afier simulating the use of the presented model the following benefits were achieved: integration of shared informations, reduction of activities that do not agregate value to the product and less dependency on human experience in some activities

Abstract:
This paper investigates two sampling strategies, dense sampling and PHOW sampling, for bag-of-features 3D CAD model retrieval. Previous methods [1] use original salient SIFT feature detection for general 3D model retrieval which does not suit the need for CAD models representation. CAD models contain mostly piecewise-smooth surfaces and thus only sharp edges can be described. To overcome these limitations, two new sampling strategies are investigated to improve the feature extraction process. Dense sampling extracts SIFT features on regular spatial grids with even spacing. Pyramid Histogram Of visual Words (PHOW) [2] extracts features on repeatedly finer scales. Both the two sampling methods extract features that are covered the whole shape. In addition, the influences of codebook size and distance metric are also studied to optimize the retrieval performance. Experiments on Purdue Engineering Benchmark [3] show that the proposed sampling techniques achieve better retrieval accuracy than the original salient SIFT sampling method.

Abstract:
Abstract The concept of “Features” has been recognized as a neutral form of communication between design and manufacturing. Since virtually all CAD systems define part models using B-Rep or CSG formats, a facility is needed to convert geometry based part models to ones which are feature based. This paper outlines the framework of a facility which would enable part models from any type of CAD system to be converted to a format which could be analyzed using a knowledge based design system. This facility relies on the user to recognize and isolate the individual features of the model and then extracts the dimensions, locations and relative positioning of the features within the model. These features are then organized into a feature graph for the construction of a feature based part representation. The procedures for the construction of this part representation include feature instantiation, feature placement and functional specification.

Micro-terrain and canopy feature extraction by breakline and differencing analysis of gridded elevation models : identifying terrain model discontinuities with application to off-road mobility modeling. Engineer Research and Development Center (U.S.), April 2021. http://dx.doi.org/10.21079/11681/40185.

Full text
Abstract:
Elevation models derived from high-resolution airborne lidar scanners provide an added dimension for identification and extraction of micro-terrain features characterized by topographic discontinuities or breaklines. Gridded digital surface models created from first-return lidar pulses are often combined with lidar-derived bare-earth models to extract vegetation features by model differencing. However, vegetative canopy can also be extracted from the digital surface model alone through breakline analysis by taking advantage of the fine-scale changes in slope that are detectable in high-resolution elevation models of canopy. The identification and mapping of canopy cover and micro-terrain features in areas of sparse vegetation is demonstrated with an elevation model for a region of western Montana, using algorithms for breaklines, elevation differencing, slope, terrain ruggedness, and breakline gradient direction. These algorithms were created at the U.S. Army Engineer Research Center – Geospatial Research Laboratory (ERDC-GRL) and can be accessed through an in-house tool constructed in the ENVI/IDL environment. After breakline processing, products from these algorithms are brought into a Geographic Information System as analytical layers and applied to a mobility routing model, demonstrating the effect of breaklines as obstacles in the calculation of optimal, off-road routes. Elevation model breakline analysis can serve as significant added value to micro-terrain feature and canopy mapping, obstacle identification, and route planning.

Abstract:
The orientation of constructed levee embankments relative to alluvial swales is a useful measure for identifying regions susceptible to backward erosion piping (BEP). This research was conducted to create an automated, efficient process to classify patterns and orientations of swales within the Lower Mississippi Valley (LMV) to support levee risk assessments. Two machine learning algorithms are used to train the classification models: a convolutional neural network and a U-net. The resulting workflow can identify linear topographic features but is unable to reliably differentiate swales from other features, such as the levee structure and riverbanks. Further tuning of training data or manual identification of regions of interest could yield significantly better results. The workflow also provides an orientation to each linear feature to support subsequent analyses of position relative to levee alignments. While the individual models fall short of immediate applicability, the procedure provides a feasible, automated scheme to assist in swale classification and characterization within mature alluvial valley systems similar to LMV.

Abstract:
The article examines the main features, general characteristics and essence of the concept of solutions journalism. The basic principles of functioning of this model of journalism in the western press and in Ukraine are given. The list and features of activity of the organizations, institutes and editorial offices supporting development of journalism of solutions journalism. The purpose of the publication is to describe the Solutions Journalism model: its features, characteristics and features of functioning, to find out the difference in the understanding of the concept of «solutions journalism» and «constructive journalism» in general. The task of the publication was to conceptualize the main trends in the development of solutions journalism in the Western and Ukrainian information space; show the main characteristics, formats of functioning and analyze the features of the concepts of «solutions journalism» and «constructive journalism». Applied research methods: at the stage of research of the history of formation of the concept of Solutions Journalism the historical method is used. The hermeneutic method of research helped in the interpretation of basic concepts, the phenomenological approach was applied in the context of considering the essence of the phenomenon of solutions journalism. At the stage of generalization of the features of the concepts of Solutions Journalism and «constructive journalism» a comparative method was used, which gave an understanding of the common components in their essence. The method of analysis allowed to expand the understanding of the purpose of Solutions Journalism as a type of social journalism and its main tasks. With the help of synthesis it was possible to comprehensively understand the concept of Solutions Journalism and understand its features. In Ukraine, this type of journalism is just emerging, but its introduction into the editorial policy of the media may have a national importance. These are regional and local media that can inform their communities about the positive solution of certain problems in other communities, and thus thanks to this model can save local journalism. In the scientific context, there is a need to outline the main differences in the understanding of the concepts of decision journalism and constructive journalism, to understand the socio-psychological need to create good news.

Abstract:
Flexible fiscal rules include mechanisms to accommodate unexpected/exogenous shocks. In countries without fiscal rules, or with rigid rules (i.e., rules without flexible features), public investment falls sharply during fiscal consolidation episodesby as much as 10 percent on average. The negative impact of fiscal consolidations on public investment disappears in countries using flexible fiscal rules.

Abstract:
To deliver infrastructure that sustain our communities, economy, and environment, we must innovate, modernize, and even revolutionize our approach to infrastructure development. Change takes courage, but as one starts down the path of innovation, what was once novel becomes more familiar, more established. The U.S. Army Corps of Engineers (USACE) is walking this path with our partners through the Engineering With Nature (EWN) Initiative, integrating human engineering with natural systems. The International Guidelines on Natural and Nature-Based Features for Flood Risk Management are the next step toward revolutionary infrastructure development—a set of real-world guidelines to help familiarize us with what was once novel. USACE and collaborators around the world have been building, learning, and documenting the best practices for constructing Natural and Nature-Based Features (NNBF) for decades. The consolidation of these lessons into a single guidance document gives decision-makers and practitioners a much-needed resource to pursue, consider, and apply NNBF for flood risk management while expanding value through infrastructure. Relationships and partnerships are vital ingredients for innovation and progress. The NNBF Guidelines was achieved because of the strong relationships in the nature-based engineering community. The magnitude and diversity of contributors to the NNBF Guidelines have resulted in a robust resource that provides value beyond a single agency, sector, or nation. Similarly, the work of incorporating NNBF into projects will require us to strengthen our relationships across organizations, mandates, and missions to achieve resilient communities. I hope you are inspired by the collaborative achievement of the NNBF Guidelines and will draw from this resource to develop innovative solutions to current and future flood risk management challenges. There is a lot we can achieve together along the path of revolutionary infrastructure development.

Abstract:
Free college proposals have become increasingly popular in many countries of the world. To evaluate their potential effects, we develop and estimate a dynamic model of college enrollment, performance, and graduation. A central piece of the model, student effort, has a direct effect on class completion, and an indirect effect in mitigating the risk of not completing a class or not remaining in college. We estimate the model using rich, student-level administrative data from Colombia, and use the estimates to simulate free college programs that differ in eligibility requirements. Among these, universal free college expands enrollment the most, but it does not affect graduation rates and has the highest per-graduate cost. Performance-based free college, in contrast, delivers a slightly lower enrollment expansion yet a greater graduation rate at a lower per-graduate cost. Relative to universal free college, performance-based free college places a greater risk on students but is precisely this feature that delivers better outcomes. Nonetheless, the modest increase in graduation rates suggests that additional, complementary policies might be required to elicit the large effort increase needed to raise graduation rates.
