Purpose – The preservation and curation of music with real-time or live electronics is challenging. The goal is not to preserve a recording of the performance but to keep the work alive by providing the means to re-perform them. The purpose of this paper is to present the theoretical and practical outcomes of the documentation, dissemination and preservation of compositions with real-time electronics (DiP-CoRE) project. Design/methodology/approach – The methodology combines methods stemming from work psychology and ergonomics with conceptual frameworks constructed according to grounded theory. Data were collected during a six months’ creative process. Subsequent interviews were conducted during confrontations with documents, including observational recordings, sketches and technical specifications. Findings – This paper demonstrates the relevance of the proposed documentation methodology for the preservation of contemporary music with live electronics, focussing on the notion of intelligibility. It brings into light the multiple perspective of the documentation of the activity in a multi-agent creative process, which encompasses what was done but also what could have been done. Research limitations/implications – The DiP-CoRE project bring to light connections between the notion of intelligibility, the thickness of the activity and boundary objects. The paper proposes further directions of research in order to embed the designed framework within digital repositories. Practical implications – The documentation methodology, designed and tested in this paper, proposes a framework for practitioners, building on video-stimulated recall as well as documents produced during the creative process. This framework requires less expertise (but a more important technical setup) than a traditional interview-based documentation framework. It thus provides opportunities for various size organizations to build methodical documentation processes and to further build on distributed expertise with computer-supported collaborative work. Originality/value – This paper proposes a new interdisciplinary documentation methodology relevant in the artistic domain, which brings together transmission with objects and by practice. It specifically defines the relation between this proposal and a high-level model for digital curation, namely, the mixed methods digital curation model. It further creates a link between documentation best practice and the ongoing research in the tracking of creative processes.

The problem of managing digital design data including drawings, specifications and other technical data in building design and construction units is a real challenge, especially when there is a need to structure the design information across building design companies. The main difficulty in this information management is the shortage of unified rules (or standards) concerning the ways how the digital design data should be gathered, archived, and preserved in the most efficient way for building design and construction units. The most important issue addressed in this work, is the standardised reference of all design data definitions.

The sensing module that converts physical or chemical stimuli into electrical signals is the core of future smart electronics in the post-Moore era. Challenges lie in the realization and integration of different detecting functions on a single chip. We propose a new design of on-chip construction for low-power consumption sensor, which is based on the optoelectronic detection mechanism with external stimuli and compatible with CMOS technology. A combination of flipped silicon nanomembrane phototransistors and stimuli-responsive materials presents low-power consumption (CMOS level) and demonstrates great functional expansibility of sensing targets, e.g., hydrogen concentration and relative humidity. With a device-first, wafer-compatible process introduced for large-scale silicon flexible electronics, our work shows great potential in the development of flexible and integrated smart sensing systems for the realization of Internet of Things applications.

In the last few years there has been a great interest in developing electronics at a molecular level (molecular electronics), e.g. to construct miniaturized electric circuits that would be much smaller than the corresponding micron-scale digital logic circuits fabricated on conventional solid-state semiconductor chips. An alternative possibility to the use of electron fluxes as a means for information processing (electronics) is that of using optical beams (photonics), but up until now scarce attention has been devoted to the possibility of developing photonics at the molecular level. In this paper we review some recent achievements in the design and construction of molecular-level systems that are capable of transferring, switching, collecting, storing, and elaborating light signals. The combination of molecular photonics with chemionics can lead to a wealth of molecular-level devices capable of information processing.

Measurement-While-Drilling (MWD) technology for oil and gas, and geothermal directional drilling exploration is pushing into ever higher temperature environments - beyond 200°C. Orientation sensors supporting these high temperature environments need to provide highly accurate elevation and tool face measurements on the order of 0.1°. Honeywell has developed a new digital high temperature down-hole accelerometer, DHTA230, capable of providing the required accuracy at the elevated temperatures of 230°C, in the rugged MWD shock and vibration environment, with expected excellent reliability and life. The DHTA230 is designed for use in the downhole environment, but is based upon a mature Honeywell accelerometer using dual vibrating beam sensing elements. These sensing elements are configured as double-ended-tuning-forks in a push-pull orientation attached onto a pendulous proof mass. This push-pull configuration provides an acceleration signal proportional to the frequency difference of the vibrating beams, an easily captured digital signal through measurement of the two vibrating beam phases. The digitized accelerometer eliminates the need for A/D electronics in the high temperature drilling environment. The DHTA230 is 0.79” in diameter with a depth of .393” at the mount flange. The ruggedized configuration of the DHTA230 is expected to provide reliable orientation measurement in high temperature direction drilling applications up to 1000h. The DHTA230 electronics incorporate ceramic hybrids with chip and wire construction. Active die are based upon proven 300°C chips developed previously for the Enhanced Geothermal Systems OM300, fabricated using Honeywell HTSOI4 process. The electronics include power conditioning providing reliable operation using a single power supply between 7V and 15V. Dual oscillator electronic circuits provide the necessary function to drive and sense the dual vibrating beams, while providing a CMOS logic level signal of the frequency pulse train. The accelerometer provides precision output up to 15g acceleration inputs, and allows sensing of higher-g vibration levels. This paper contains information on the target application, electrical and mechanical component requirements, design, fabrication approach, and initial prototype testing. The DHTA230 is expected to enter production transition in 2015.

Currently, there is a growing demand for methodologies that best qualify engineering students at universities. These methodologies require a substantial change in Engineering Teaching programs improving or even changing the traditional ways of imparting knowledge to students. In Power Electronics (PE) study the factors that make learning difficult for Electrical Engineering students, in order for them to achieve full understanding of the subjects addressed in a first discipline in this area, are the academic maturity required coupled with their multidisciplinary nature. The problem is aggravated in practical activities, which demand the availability of a laboratory infrastructure with specific characteristics not always available. An alternative for the study of PE, with a more contemporary focus, is to introduce, through a new Instructional Design (ID) Project, not only the incorporation of more Hands-On activities that approach truly meaningful (authentic) contents. But also, new methodologies and technologies to support educational objectives that make full use of Digital Information and Communication Technologies (DICTs).This work proposes to develop and carry out a methodological design of a blended teaching for a power-electronics-based practical training program (PEBPTP) for students of the Electrical Engineering Course of the Federal University of Maranhão in Brazil. The proposed program is mainly based on the use of a digital controller (unified) based on FPGA, developed and realized specifically for control and power inverters study. From controller´s VHDL Code already realized, a Reuse Logic Block is generated (Intellectual Property Core (IP Core)), for use within the LabVIEW FPGA Hardware Description Environment. A Graphical Interface (GUI), more intuitive, and developed from the LabVIEW environment, will support the realization of the PEBPTP, for parameterizing the Controller, and show relevant figures of merit of the performance of the converter being study. The active methodologies, converging with the diverse possibilities of resources of the DICTs, implanted in the classroom, with the adequate contextualization of the specific resources of each area, contribute increasingly to the student being protagonist of their own knowledge construction. Finally is proposed, and in full adherence to a novel trend, that both the PEBPTP and the unified controller previously developed in FPGA are embedded in what is being named Lab-on-a-Chip (LoC). This embedded structure will allow access to the laboratory hands-on program via a web service that uses a fully programmable logic device (PLD) that incorporates an integrated structure known as System-on-a-Chip (SoC). The above proposals and experiences involve the mastery not only of curricular and technological knowledge, inherent to the training of an engineer, but of mainly, the pedagogical technological knowledge and correct use of DICTs. At this point, in particular, is founded our contribution within the context of Engineering Teaching, to advance in the improvement or perhaps in the modification of the "classroom" of engineering courses, which today go beyond the physical space of the university.

The current technologies behind the design of semiconductor integrated circuits allow embedding billions of components in a singe silicon die, enabling the construction of very complex circuits in a tiny space, dissipating little energy and producing huge amounts of useful computational work. However, the current levels of integration for electronic components in silicon and similar materials are not easily managed, as parameter variations grow steadily, making the design tasks increasingly challenging. Synchronous techniques have dominated the digital system design landscape for many decades, but their costs are increasingly hard to cope with. Asynchronous design and particularly quasi-delay insensitive design promises to deal with the same challenges more gracefully in current advanced nodes, and possibly irrevocably in future technology nodes. This article proposes a review of the state of the art in using asynchronous circuit design techniques to achieve energy-efficient and robust digital circuit and system design. In particular, the definition of a robust digital circuit comprises addressing several aspects to which a digital system design is expected to be robust to, including: (1) voltage variations; (2) process variations; (3) temperature variations; (4) circuit aging. Besides addressing energy-efficiency and all the mentioned robustness aspects, this work also approaches some of the state-of-the-art tools available to deal with asynchronous design, and points to desirable research development to be conducted in these subjects in the future.

Topographic maps in digital and electronic forms are created on the basis of available paper topographic maps or on the basis of primary materials of geodetic surveys. Geodetic surveys are performed both by ground methods, without the use of photogrammetric materials, and on the basis of materials obtained as a result of ground phototheodolite or aerial photography. The construction of a digital terrain model is a multi-stage process, which consists of a significant number of interconnected operations performed at the stage of in-house processing of the results of geodetic measurements carried out during engineering and geodetic surveys. The quality of the final result of modeling depends on the quality of each stage of construction of a digital terrain model, so it is extremely important to pay attention to all technological processes of model construction. The digital relief model is considered as an ordered set of triangular faces constructed by the Delaunay algorithm. The main condition of this type of triangulation is that in the middle of the circle described around any triangle can not be the vertex of another triangle. Construction of a digital terrain model based on the results of geodetic surveying of the area in the general case can be divided into several stages. At the beginning, an automated construction of triangulation is performed on the basis of the results of geodetic measurements, which carry information about three-dimensional coordinates of survey points. Allotments adjust the display of horizontals. Regardless of the selected surface display style, the surface model is a grid of triangles. At the next stage of construction of the digital model of a relief carry out visual control of the created model and if necessary carry out editing of elements of a surface and change of position of edges of triangulation for change of position of horizontals. The last stage of building a digital terrain model based on the results of geodetic surveying of the area is the design of modeling results, the application of individual styles of reflection for individual areas of the surface and the creation of mountain strokes and signatures of horizontals.

Modern construction of bridge crossings is impossible without engineering and geodetic works. When transferring a project to the terrain, it is necessary to perform measurements in the horizontal and vertical planes with high accuracy. Geodetic works, to secure the design position and dimensions of both the entire sporida and its surrounding parts, to be carried out by procrastination before the construction of the bridge. Geodetic work during the construction of bridges and other structures is a complex of measurements, calculations and constructions on the ground, in which the design placement of structures must be ensured. The purpose of the article is to consider engineering and geodetic works during the construction of a bridge as part of a combined bridge crossing. At the stages of the construction of the bridge, the accuracy of the project is required, which will ensure geodesic work. These include: the breakdown of bridge supports at different stages of their construction, control of the erection of the superstructure and its installation on the support parts. To perform geodetic works such equipment as an electronic total station "Sokkia 630" and a digital level of the brand "Trimble DiNi" were used. The coordinates of the benchmarks were obtained and entered into the plan of the area. To work with them, anchors were driven into the asphalt and soil, photographed and entered into the documentation. On the pillars of the bridge were glued marks for the notch of the device, with a reflective effect. The data of coordinates and heights were entered into the memory of the total station. The method and procedure for geodetic works during the installation of bridge spans depend on their design and materials. At present, the most common methods of superstructures erection include hinged and semi-hinged assembly, assembly on the slipway, assembly on the shore with subsequent thrusting. When installing superstructures, the main tasks of geodetic support are to determine the straightness of the main beams and measure the so-called building lift. In the practice of bridge building, the degree of use of industrial construction methods is growing, that is, the manufacture of individual structural blocks with their subsequent connection at a regular place, which contributes to an increase in labor productivity and the quality of bridges.

The traditional classroom has been impacted by the digital teaching resources. Students are no longer satisfied with the traditional teaching mode of teacher teaching and student learning. Combined with the characteristics of a virtual reality-interactive classroom, the design of a virtual reality-interactive classroom based on the deep learning algorithm is proposed. This paper divides the teaching activities of the VR-interactive classroom into two parts: in-class learning activities and after-class learning activities. The software is used to design the interactive test. The emphasis and difficulty in the virtual reality-interactive classroom are taken as the development object to realize the construction of the virtual reality-interactive classroom. The simulation results show that the statistical output of teaching quality evaluation can be obtained from the quantitative regression analysis of the factors involved in VR classroom participation.

Instrumental digital didactics is based on the use of various digital means of obtaining, processing, and interpreting empirical data in accordance with the logic of scientific method and engineering design. Appropriate teaching techniques reflect the STEM approach to teaching natural science and engineering subjects. The use of the equivalent circuit created on the NI Multisim platform to investigate the characteristics of electric circuits’ components creates favorable didactic conditions. The methodological approaches proposed by the authors are demonstrated by the examples of determining the parameters of technologically advanced devices - photoelectric converter (for example, determining its maximum power point, as well as Fill Factor) and supercapacitor (for example, designating changes in charging and discharging characteristics depending on the type of construction). In such educational projects the parameters of the circuit components obtained by the equivalent circuit method are compared with the specifications of commercial devices available on the market. This approach, on the one hand, demonstrates statistical errors of results to the students, and on the other hand, it is a source of sufficient data for constructing an equivalent circuit of devices without prior experimental research. It is shown that the use of equivalent circuits in a computer simulation environment to replace real electronic and electrical devices, measuring systems and equipment with their virtual counterparts expands the didactic possibilities. Techniques based on the versatile use of digital didactic tools are being actively developed and implemented in the MANLab STEM-laboratory of the National Centre “Junior Academy of Sciences of Ukraine”.

ABSTRACT
 Dummy Load is used as an imitation load on the loading practice on a PLTD or PLTS generator. The existing dummy load currently installed is the conventional resistive dummy load type which is dominant at active power. The problem is that the dummy load does not yet represent the actual actual load condition, namely the RLC load. The power consumption by the dummy load is controlled by varying the firing angle ‘α’ of the thyristor- pair [1] Therefore it is necessary to improve the function of the dummy load by improving and developing the design and construction. The design of the construction improvement and development will be carried out on the main components and the digital computerized monitoring and control system for its operation. In this paper, the microcontroller-based electronic load controller (ELC) as a voltage and frequency stabilizer is designed when the dummy load is operated. This tool can prevent damage due to the frequency and output voltage of the distribution system. The result of the reconstruction is to make the PLTD / PLTS dummy load that has the ability of dummy load RLC balanced load / unbalanced load for operating loading practices, where in operation it uses a digital computerized control system that can programmed manually / auto and has a facility / feature event recorder.

Modem microelectronic technology.gives opportunities to build digital circuits of huge complexity and provides a wide diversity of logic building blocks. Although logic designers have been building circuits for many years, they have realized that advances in microelectronic technology are outstripping their abilities to make use of the created opportunities. In this paper, we present the fundamentals of a logic design methodology which meets the requirements of today's complex circuits and modem building blocks. The methodology is based on the theory of general full-decompositions which constitutes the theory of digital circuit structures at the highest abstraction level. The paper explains the theory and shows how it can be used for digital circuit synthesis. The decomposition methodology that is presented ensures “correctness by construction” and enables very effective and efficient post-factum validation. It makes possible extensive examination of the structural features of the required information processing in relation to a given set of objectives and constraints.

Two-level pipelined systolic array can attain parallelism down to lower levels and provide much higher throughput and computational speed than conventional ones. This paper presents a design procedure starting from an algorithm representation, called Dependence Graph (DG). Arrays with different performances can be obtained by applying the various linear transformation matrices on DG. Image resampling is a process for image construction and display. It has important applications in image processing or in digital TV. In this paper, two design considerations are applied to build high-performance VLSI image resampler. First, two-level pipelined systolic array is designed to maximize parallelism and also make VLSI implementation highly feasible. Second, a modified two-pass resampling scheme is devised to reduce the amount of required storage and increase the concurrency between two passes of resampling. This image resampler can get a throughput of one pixel per clock period being smaller than the latency of an adder. The requirement for storage is only several line buffers.

The Destiny-class CyberCANOE (Destiny) is a Hybrid Reality environment that provides 20/20 visual acuity in a 13-foot-wide, 320-degree cylindrical structure comprised of tiled passive stereo-capable organic light emitting diode (OLED) displays. Hybrid Reality systems combine surround-screen virtual reality environments with ultra-high-resolution digital project-rooms. They are intended as collaborative environments that enable multiple users to work minimally encumbered for long periods of time in rooms surrounded by data in the form of visualizations that benefit from being displayed at resolutions matching visual acuity and/or in stereoscopic 3D. Destiny is unique in that it is the first Hybrid Reality system to use OLED displays and it uses a real-time GPU-based approach for minimizing stereoscopic crosstalk. This paper chronicles the non-trivial engineering research and attention-to-detail that is required to develop a production quality hybrid-reality environment by providing details about Destiny’s design and construction process. This detailed account of how a Hybrid Reality system is designed and constructed from the ground up will help VR researchers and developers understand the engineering complexity of developing such systems. This paper also discusses a GPU-based crosstalk mitigation technique and evaluation, and the use of Microsoft’s augmented reality headset, the HoloLens, as a design and training aid during construction.

Full textAbstract:
Analog functions have been implemented in a Silicon-on-Insulator (SOI) process optimized for high-temperature (>225°C) operation. These include a linear regulator/reference block that supports input voltages up to 50V and provides multiple independent voltage outputs. Additional blocks provide configurable sensor excitation levels of up to 10V DC and/or 20V AC-differential, with current limiting and monitoring. A dual-channel Programmable-Gain-Instrumentation Amplifier (PGIA) and a high-level AC input block with programmable gain and offset serve signal conditioning, gain, and scaling needs. A multiplexer and analog buffer provide an output that is scaled and centered for down-stream A-to-D conversion. Limited component availability and high component counts deter development of sensing and control electronics for extreme temperature (>200°) applications. Systems require front-end power conditioning, sensor excitation and monitoring, response amplification, scaling, and multiplexing. Back-end Analog-to-Digital conversion and digital processing/control can be implemented using one or two integrated circuit chips, whereas the front-end functions require component counts in the dozens. The low level of integration in the available portfolio of SOI devices results in high component count when constructing signal conditioning interfaces for aerospace sensors. These include quasi-DC sensors such as thermo-couples, strain-gauges, bridge transducers as well as AC-coupled sensors and position transducers, such as Linear Variable Differential Transducers (LVDT's). Furthermore, a majority of sensor applications are best served by excitation/response voltage ranges that typically exceed the voltage range of digital electronics (either 5V or 3.3V in currently available digital IC's for use above 200°C). These constraints led Embedded Systems LLC to design a generic device which was implemented by Honeywell as an analog ASIC (Application Specific Integrated Circuit). This paper will describe the ASIC block-level capabilities in the context of the typical applications and present characterization data from wafer-level testing at the target temperature range (225C). This material is based upon work performed by Honeywell International under a subcontract from Embedded Systems LLC, funding for which was provided by the U.S. Air Force Small Business Innovative Research program.

Full textAbstract:
This paper presents a new virtual reality (VR)-based approach to advanced learnings and experiences of the circular economy (CE) in the construction industry. The approach involves incorporating game design and a building information modelling (BIM) digital twin of a purposed CE prototype building. Our novel approach introduces VR environments designed to provide a visual representation of materials and components that can be reintroduced into the supply chain at the end of life and their removal procedures and material provenance. A case study methodology was applied to a purposely designed CE building, namely the Legacy Living Lab (L3). To reflect the real-life building, L3’s BIM model was combined with Unify game software to advance the literature in three key areas. First, the research investigates VR tools that will allow building designers to view and implement their strategies to advance CE design. Second, this research proposes an advanced VR tool to visualise the bill of quantities (BoQ) and material stock embedded in the studied building, further understanding concepts such as buildings as material banks. Finally, the proposed VR environment defines CE techniques implemented within the case study to be disseminated across the vast construction industry. This VR research identifies three key pillars in reducing the waste generated by the construction industry: education, documentation and visualisation. Furthermore, this paper provides a visual link between the BIM, BoQ and resiliency of the selected materials.

Background: In Code Division Multiple Access (CDMA)/Multi-Carrier CDMA (MCCDMA), Walsh-Hadamard codes are widely used for its orthogonal characteristics, and hence, it leads to good contextual connection property. These orthogonal codes are important because of their various significant applications. Objective: To use the Mach–Zehnder Interferometer (MZI) for all-optical Walsh-Hadamard codes is implemented in this present paper. Method: The Mach–Zehnder Interferometer (MZI) is considered for the Tree architecture of Semiconductor Optical Amplifier (SOA). The second-ordered Hadamard and the inverse Hadamard matrix are constructed using SOA-MZIs. Higher-order Hadamard matrix (H4) formed by the process of Kronecker product with lower-order Hadamard matrix (H2) is also analyzed and constructed. Results: To experimentally get the result from these schemes, some design issues e,g Time delay, nonlinear phase modulation, extinction ratio, and synchronization of signals are the important issues. Lasers of wavelength 1552 nm and 1534 nm can be used as input and control signals, respectively. As the whole system is digital, intensity losses due to couplers in the interconnecting stage may not create many problems in producing the desired optical bits at the output. The simulation results were obtained by Matlab-9. Here, Hadamard H2 (2×2) matrix output beam intensity (I ≈ 108 w.m-2) for different values of inputs. Conclusion: Implementation of Walsh-Hadamard codes using MZI is explored in this paper, and experimental results show the better performance of the proposed scheme compared to recently reported methods using electronic circuits regarding the issues of versatility, reconfigurability, and compactness. The design can be used and extended for diverse applications for which Walsh-Hadamard codes are required.

Advances in consumer electronics products and the technology seen in personal computers, digital cameras, and smartphones phones have led to the price/performance ratio of sensors and processors falling dramatically over the last decade. In particular, many consumer products are packaged with small cameras, gyroscopes, and accelerometers, all sensors that are needed for autonomous robots in GPS-denied environments. The low mass and small form factor make them particularly well suited for autonomous flight with small flying robots. In this work, we present the first fully autonomous smartphone-based system for quadrotors. We show how multiple quadrotors can be stabilized and controlled to achieve autonomous flight in indoor buildings with application to smart homes, search and rescue, monitoring construction projects, and developing models for architecture design. In our work, the computation for sensing and control runs on an off-the-shelf smartphone, with all the software functionality embedded in a smartphone app. No additional sensors or processors are required for autonomous flight. We are also able to use multiple, coordinated autonomous aerial vehicles to improve the efficiency of our mission. In our framework, multiple vehicles are able to plan safe trajectories avoiding inter-robot collisions, while concurrently building in a cooperative manner a three-dimensional map of the environment. The work allows any consumer with any number of robots equipped with smartphones to autonomously drive a team of quadrotor robots, even without GPS, by downloading our app and cooperatively build three-dimensional maps.

Full textAbstract:
Polar codes are featured by their low encoding/decoding complexity for symmetric binary input-discrete memoryless channels. Recently, flexible generic Successive Cancellation List (SCL) decoders for polar codes were proposed to provide different throughput, latency, and decoding performances. In this paper, we propose to use polar codes with flexible fast-adaptive SCL decoders in Digital Video Broadcasting (DVB) systems to meet the growing demand for more bitrates. In addition, they can provide more interactive services with less latency and more throughput. First, we start with the construction of polar codes and propose a new mathematical relation to get the optimized design point for the polar code. We prove that our optimized design point is too close to the one that achieves minimum Bit Error Rate (BER). Then, we compare the performance of polar and Low-Density Parity Check (LDPC) codes in terms of BER, encoder/decoder latencies, and throughput. The results show that both channel coding techniques have comparable BER. However, polar codes are superior to LDPC in terms of decoding latency, and system throughput. Finally, we present the possible performance enhancement of DVB systems in terms of decoding latency and complexity when using optimized polar codes as a Forward Error Correction (FEC) technique instead of Bose Chaudhuri Hocquenghem (BCH) and LDPC codes that are currently adopted in DVB standards.

An energy storage system using secondary batteries combined with advanced power control schemes is considered the key technology for the sustainable development of renewable energy-based power generation and smart micro-grids. The performance of energy storage systems in practical application mainly depends on their power conditioning systems. This paper proposes a silicon carbide-based multifunctional power conditioning system for the vanadium redox flow battery. The proposed system is a two-stage circuit topology, including a three-phase grid-tie inverter that can perform four-quadrant control of active and reactive power and a bi-directional multi-channel direct current converter that is responsible for the fast charging and discharging control of the battery. To achieve the design objectives, i.e., high reliability, high efficiency, and high operational flexibility, silicon carbide-based switching devices, and advanced digital control schemes are used in the construction of a power conditioning system for the vanadium redox flow battery. This paper first describes the proposed system topologies and controller configurations and the design methods of controllers for each converter in detail, and then results from both simulation analyses and experimental tests on a 5 kVA hardware prototype are presented to verify the feasibility and effectiveness of the proposed system and the designed controllers.

The design and construction of any marine vessel designed on a computer-assisted design (CAD) system, from a nuclear aircraft carrier to the smallest work boat, requires the interaction of many electronic databases, all of which must be continually updated for the work to proceed. The exchange of this information, especially geometry, in digital format is accomplished using many different tools and techniques. Much has been presented to the marine community about the tools used, such as the Initial Graphics Exchange Specification (IGES) and the Standard for the Exchange of Product Model Data (STEP), and how these tools might be used for exchanges in the future, but little has been presented on how production data exchanges actually occur. At Electric Boat, current submarine programs cannot wait for future data transfer solutions. Design and construction data must be exchanged among various activities, internal and external, with such volume as to make manual reentry of data an unrealistic solution. Because of the complexities associated with the electronic exchange of these data, the General Dynamics (GD) Marine organization of Electric Boat has a dedicated group that both performs production data exchanges and researches and implements new methods of electronic transfer. This paper discusses the rationale for and the formation of the data exchange group at Electric Boat, along with its place within GD Marine. It then presents an overview of the tools used by the group and how production transfers occur, both routine and unique. Notable transfers provide examples of how the group works to solve transfer problems. Importantly, this paper shows how many of the exchange standards developed for the marine industry actually work in production. Special emphasis will be placed on the exchange of solid models in a day-to-day environment. The paper concludes with a look at the future of production data exchanges for Electric Boat and the larger marine industry.

A carrier-based grid synchronous method is proposed to develop the system efficiency, phase and power quality of the inverter output waves. The operating principle of a single-phase phase synchronous inverter (SPSI) is introduced, with proper synchronous paid to the switching-frequency synchronizing voltage made by the interleaved process, as well as actual mitigation approaches. In the construction of the SPSI, input and output filters are electrically coupled with the two sides of an inverter. The inverter power electronic switches and other electrical components are operated by carrier-based grid synchronous controller (CBGSC) with PWM regulator. The SPSI is designed and implemented with the Toshiba 40WR21 IGBT, Digital Microcontroller pulse controller (DMPC) and 4N35 Optocoupler with a fundamental frequency of 50Hz. The other parameters are considered as load resistance, =11Ω, duty cycle, 85%, carrier frequency, 2.5kHz and input DC voltage, ± 340V. In addition, LCL lowpass grid filters are used to convert squire wave to sine wave with required phase and frequency. Finally, the simulated and experimental results obtained with a carrier-based grid synchronous SPSI experimental prototype are exposed for justification, showing the phase error of 55% improvement, reduced 11% of THD and the conversion efficiency of 97.02% highly predicted by the proposed design technique to improve the microgrid system.

Purpose This paper presents a novel design method for keyboard circuits. The purpose of this study is to enable a single-board computer with fewer pins to recognize a keyboard system consisting of a large number of switches. Through the study of different kinds of keyboard circuits, a general circuit schematic design method is abstracted. Several experiments are conducted to prove the feasibility of the proposed circuit design method. Design/methodology/approach Conventional circuit schematic diagrams are often limited to two-dimensional planes. Through investigating higher dimensional alternatives, this paper proposes to place components in high-dimensional geometry before connecting all components. A multi-pin switch construction method is proposed to allow the switches to be arranged on the vertices of high-dimensional geometry and be connected sequentially to form the keyboard system. This proposed system can allow a keyboard system consisting of a large number of switches to be recognized by a single-board computer with less available pins. Findings The design scheme proposed in this paper can read more switch states with limited Input/Output pins. With the increase of the number of Input/Output ports and pins, the number of simultaneously identifiable switches increases exponentially, which is suitable for sensor design of array type. Research limitations/implications Compared with the classical keyboard circuits, the circuit designed using the proposed method will lead to a slightly longer recognition time for each key. This can be compensated by a single-board computer with a modestly higher clock speed. Originality/value The circuit schematic design method based on high-dimensional geometry is introduced for the first time. The feasibility of the proposed method is verified by the original experiments. The proposed approach is of importance in guiding the design of new analog and digital sensor circuit systems.

Full textAbstract:
With medium wave infrared (MWIR) focal plane array-based (FPA) compressive imaging (CI), high-resolution images can be obtained with a low-resolution MWIR sensor. However, restricted by the size of digital micro-mirror devices (DMD), aperture interference is inevitable. According to the system model of FPA CI, aperture interference aggravates the blocky structural artifacts (BSA) in the reconstructed images, which reduces the image quality. In this paper, we propose a novel DMD mask design strategy, which can effectively suppress BSA and maximize the reconstruction efficiency. Compared with random binary codes, the storage space and computation cost can be significantly reduced. Based on the actual MWIR FPA CI system, we demonstrate the proposed DMD masks can effectively suppress the BSA in the reconstructed images. In addition, a new evaluation index, blocky root mean square error, is proposed to indicate the BSA in FPA CI.

Full textAbstract:
Engineering, Procurement, and Construction (EPC) projects span the entire cycle of industrial plants, from bidding to engineering, construction, and start-up operation and maintenance. Most EPC contractors do not have systematic decision-making tools when bidding for the project; therefore, they rely on manual analysis and experience in evaluating the bidding contract documents, including technical specifications. Oftentimes, they miss or underestimate the presence of technical risk clauses or risk severity, potentially create with a low bid price and tight construction schedule, and eventually experience severe cost overrun or/and completion delays. Through this study, two digital modules, Technical Risk Extraction and Design Parameter Extraction, were developed to extract and analyze risks in the project’s technical specifications based on machine learning and AI algorithms. In the Technical Risk Extraction module, technical risk keywords in the bidding technical specifications are collected, lexiconized, and then extracted through phrase matcher technology, a machine learning natural language processing technique. The Design Parameter Extraction module compares the collected engineering standards’ so-called standard design parameters and the plant owner’s technical requirements on the bid so that a contractor’s engineers can detect the difference between them and negotiate them. As described above, through the two modules, the risk clauses of the technical specifications of the project are extracted, and the risks are detected and reconsidered in the bidding or execution of the project, thereby minimizing project risk and providing a theoretical foundation and system for contractors. As a result of the pilot test performed to verify the performance and validity of the two modules, the design risk extraction accuracy of the system module has a relative advantage of 50 percent or more, compared to the risk extraction accuracy of manual evaluation by engineers. In addition, the speed of the automatic extraction and analysis of the system modules are 80 times faster than the engineer’s manual analysis time, thereby minimizing project loss due to errors or omissions due to design risk analysis during the project bidding period with a set deadline.

Background Traditionally, digital health data management has been based on electronic health record (EHR) systems and has been handled primarily by centralized health providers. New mechanisms are needed to give patients more control over their digital health data. Personal health libraries (PHLs) provide a single point of secure access to patients' digital health data and enable the integration of knowledge stored in their digital health profiles with other sources of global knowledge. PHLs can help empower caregivers and health care providers to make informed decisions about patients’ health by understanding medical events in the context of their lives. Objective This paper reports the implementation of a mobile health digital intervention that incorporates both digital health data stored in patients’ PHLs and other sources of contextual knowledge to deliver tailored recommendations for improving self-care behaviors in diabetic adults. Methods We conducted a thematic assessment of patient functional and nonfunctional requirements that are missing from current EHRs based on evidence from the literature. We used the results to identify the technologies needed to address those requirements. We describe the technological infrastructures used to construct, manage, and integrate the types of knowledge stored in the PHL. We leverage the Social Linked Data (Solid) platform to design a fully decentralized and privacy-aware platform that supports interoperability and care integration. We provided an initial prototype design of a PHL and drafted a use case scenario that involves four actors to demonstrate how the proposed prototype can be used to address user requirements, including the construction and management of the PHL and its utilization for developing a mobile app that queries the knowledge stored and integrated into the PHL in a private and fully decentralized manner to provide better recommendations. Results To showcase the main features of the mobile health app and the PHL, we mapped those features onto a framework comprising the user requirements identified in a use case scenario that features a preventive intervention from the diabetes self-management domain. Ongoing development of the app requires a formative evaluation study and a clinical trial to assess the impact of the digital intervention on patient-users. We provide synopses of both study protocols. Conclusions The proposed PHL helps patients and their caregivers take a central role in making decisions regarding their health and equips their health care providers with informatics tools that support the collection and interpretation of the collected knowledge. By exposing the PHL functionality as an open service, we foster the development of third-party applications or services and provide motivational technological support in several projects crossing different domains of interest.

The development of information modeling technologies for construction offers new tasks to develop operational models for facilities, which are locate in most difficult conditions, here an important example is the marine Arctic ports. To build a life cycle model, reliable long-time information about hydrometeorological conditions for the selected port facility is needed. It also requires accurate data on the design and past loads. We offer the basic methods for obtaining the initial data for operation BIM model subject to the technical and design documentation are absent, what is a common practice for old facilities. The main theses for development of information BIM model for a marine port’s facilities exploitation in the Arctic are proposed in this paper. At the initial stage of description of the structure life cycle, it is necessary to develop an electronic passport of the facility that would contain the basic geometric characteristics of the structures elements, the information about the applied materials and their physical and mechanical properties, coordinates of the plan and deformation geodetic network in the digital format. At the next stage, it is necessary to provide automated monitoring for measuring the main parameters of loads, deformations and climatic conditions, which in combination ensure the safety of the port’s structures.
