Keywords: ab initio; electronic structure; FANCI; method development; Python Abstract Fanpy is a free and open-source Python library for developing and testing multideterminant wavefunctions and related ab initio methods in electronic structure theory. The main use of Fanpy is to quickly prototype new methods by making it easier to convert the mathematical formulation of a new wavefunction ansätze to a working implementation. Fanpy is designed based on our recently introduced Flexible Ansatz for N-electron Configuration Interaction (FANCI) framework, where multideterminant wavefunctions are represented by their overlaps with Slater determinants of orthonormal spin-orbitals. In the simplest case, a new wavefunction ansatz can be implemented by simply writing a function for evaluating its overlap with an arbitrary Slater determinant. Fanpy is modular in both implementation and theory: the wavefunction model, the system's Hamiltonian, and the choice of objective function are all independent modules. This modular structure makes it easy for users to mix and match different methods and for developers to quickly explore new ideas. Fanpy is written purely in Python with standard dependencies, making it accessible for various operating systems. In addition, it adheres to principles of modern software development, including comprehensive documentation, extensive testing, quality assurance, and continuous integration and delivery protocols. This article is considered to be the official release notes for the Fanpy library.

Keywords Tissue P System; Wireless Sensor Network; Multi-Objective problem; Task Assignment; Decision Support System; Parallel computing; Sustainable computing Abstract The contemporary wireless sensor applications employ a Heterogeneous Wireless Sensor Network (HeWSN) to achieve its multi-objective missions. Modern wireless nodes constituting the HeWSN are more versatile in terms of its capabilities, functionalities, and applications. Assigning tasks in a dynamic HeWSN environment are challenging due to its inherent heterogeneous properties and capabilities. The investigation of existing task assignment algorithms reveals (i) the majority of the existing task assignment algorithms were designed for the homogeneous environment, (ii) most of the nature-inspired algorithms were built for centralized architecture. Scheduling tasks by existing task assignment algorithms lead to underutilization of resources as well as to the rapid depletion of network resources. To this end, a novel, distributed, heterogeneous task assignment algorithm adhering the modern sensors capabilities, functionalities and sensor application to attain sustainable computing is required. Based on the investigation, Tissue P-System inspired task assignment algorithm for the distributed heterogeneous WSN has been modelled. The experimental analyses of the proposed method have been self-evaluated as well as compared with the corresponding recent benchmark algorithms under various conditions and its performance metrics are analysed.

Given the ubiquity of interfaces on computing devices, it is essential for future Information Systems (IS) professionals to understand the ramifications of good user interface (UI) design. This article provides instructions on how to efficiently and effectively teach IS students about "fit," a Human-Computer Interaction (HCI) concept, through a paper prototyping activity. Although easy to explain, the concept of "fit" can be difficult to understand without repeated practice. Practically, designing "fit" into UIs can be cost-prohibitive because working prototypes are often beyond students' technical skillset. Accordingly, based on principles of active learning, we show how to use paper prototyping to demonstrate "fit" in a hands-on class exercise. We provide detailed stepby-step instructions to plan, setup, and present the exercise to guide students through the process of "fit" in UI design. As a result of this activity, students are better able to employ both theoretical and practical applications of "fit" in UI design and implementation. This exercise is applicable in any course that includes UI design, such as principles of HCI, systems analysis and design, software engineering, and project management.

Drilling and boring -- Models, Control systems -- Models, Vibration -- Models, and Oil well drilling rigs -- Models

This paper presents a control system design methodology for the drill-string rotary drive and draw-works hoist system aimed at mature drilling rig retrofitting. The rotary drive is equipped with an active damping speed control system featuring a proportional-integral speed controller readily available within modern controlled electrical drives, extended with drill-string back-spinning prevention scheme for the case of stuck tool. The draw-works hoist system features a tool normal force (Weight-on-Bit) controller with tool longitudinal speed (Rate-of-Penetration) limiting functionality. The design of proposed control systems has been based on suitable control-oriented process models and damping optimum criterion which guarantees a desired level of closed-loop system damping. The proposed drilling control systems have been verified on a downscaled laboratory experimental setup, which represents a necessary pre-requirement before these systems are tested in the field.

Sensors

Keywords Raspberry Pi; BeagleBone; Sharks Cove; Waspmote Abstract Arduino, an open-source electronics platform, has become the go-to option for anyone working on interactive hardware and software projects. An Arduino board (such as the Uno) connected to a breadboard with plugins such as inputs, sensors, lights, and displays can be controlled by a code written in the Arduino development environment. How to achieve this is by prototyping with Arduino. Prototyping with Arduino has grown in popularity with the increased use of the Arduino platform. Prototyping with Arduino, however, is not an easy task for nonprogrammers with interest in the field. With increased public interest in the field will come a need for accessible information. This paper presents a methodical literature review intended to intensively analyze and compare existing primary studies on prototyping with Arduino. We found about 130 of such studies, all peer-reviewed and published within the last 15 years, including these years (2015--2020). These studies were tediously and carefully chosen through a three-step process. In this paper, a cautious analysis of selected studies was followed by a clear description of the methods applied. The methods were categorized according to the success rate of the studied prototypes. Results obtained can be used in researches on the best technique to adopt while prototyping with Arduino. They can also be used in electronics researches and by individuals who wish to obtain a guide on prototyping with Arduino despite lacking grounded knowledge of the subject matter.

Satellite communications, Antennas (Electronics) -- Design and construction, Waveguides -- Design and construction, Sintering, 3D printing, Satellite communications, and Computer-aided design

Keywords: additive manufacturing; fused filament fabrication; phase shifter; reconfigurable; selective laser sintering; waveguide Abstract This work presents the design and manufacturing of a K-band reconfigurable phase shifter completely implemented in waveguide technology for reduced insertion loss, good matching, and large phase shifting range. The device is based on the combination of a short slot coupler and two tunable reactive loads implemented as a section of short-circuited waveguide where an adjustable metallic post is inserted. Three prototypes of this design have been manufactured using different techniques (conventional computer numerical control machining, a low-cost fused filament fabrication technique and direct metal laser sintering) in order to assess its performance for different applications. The prototypes have been characterized experimentally and the achieved results are evaluated and compared. The proposed phase shifter, since it is fully developed in waveguide technology, eliminates the need of adding transitions to planar structures in order to integrate lumped components like pin diodes or varactors. Therefore, this device has a great potential in high-power beam steering phased arrays.

Neural networks -- Analysis, Electrical engineering -- Analysis, Neural network, and Electrical engineering

Keywords Convolutional neural network; Hardware acceleration; Rapid system prototyping; Binarization; FPGA Abstract The huge model size and high computational complexity make emerging convolutional neural network (CNN) models unsuitable to deploy on current embedded or edge computing devices. Recently the binary neural network (BNN) is explored to help reduce network model size and avoid complex multiplication. In this paper, a binary network acceleration framework for rapid system prototyping is proposed to promote the deployment of CNNs on embedded devices. Firstly trainable scaling factors are adopted in binary network training to improve network accuracy performance. The hardware/software co-design framework supports various compact network structures such as residual block, 1 x 1 squeeze convolution layer, and depthwise separable convolution. With flexible network binarization and efficient hardware architecture optimization, the acceleration system is able to achieve over 2 TOPS throughput performance comparable to modern desktop GPU with much higher power efficiency.

Machine learning -- Analysis

Keywords Production; Lead Time Prediction; AutoML; Machine Learning Abstract Many Small and Medium Enterprises in the domain of Make-To-Order- and Small-Series-Production struggle with accurately predicting lead times of highly customisable orders. This paper investigates an approach using AutoML integrated into existing enterprise systems in order to enable Lead Time Prediction based on Machine Learning models. This prediction is based on both order data from an ERP system as well as real-time factory state informed by an IIoT platform. We used simulation data to feed the AutoML model generation and developed a lightweight web-based microservice around it to infer lead times of incoming orders during live production. Using industry standards, this microservice can be seamlessly integrated into existing system landscapes. The simplicity of AutoML systems allows for swift (re)training and benchmarking of models but potentially comes at the cost of overall lower model quality.

Byline: Nicolo Dossi, Fabio Terzi, Evandro Piccin, Rosanna Toniolo, Gino Bontempelli Keywords: Pencil-drawn sensing devices; Pen-drawn sensitive elements; Conductive filament deposition; 3D printed sensors; Direct writing; Contact and non-contact deposition methods Abstract The growing demand for low cost and easy to use analytical devices requires the development of reliable and rapid deposition strategies suitable for changing easily planned designs and applicable to a wide range of materials for assembling conductive tracks and sensitive elements. Further important challenges to be pursued are the possibility of using readily available instrumentation and reducing power consumption and hazardous chemical waste. This review provides an overview of the use of portable day-to-day writing tools, such as pencils and pens, for the rapid and on-demand deposition of conductive patterns on different substrates, with particular emphasis on the assembly of "Do It Yourself" sensors. Moreover, layer-by-layer deposition of simple or even complex three dimensional (3D) circuits, resorting to pressure driven extrusion of conductive filaments is considered. Future perspectives and potentiality of these emerging technologies for assembling sensors are also explored.

Rapid prototyping

Byline: Sherif Moussa, Ahmed M. Abdel Razik, Adel Omar Dahmane, Claude D'Amours, Habib Hamam Keywords: component; OFDM; MIMO; error-control coding; parity bit selected spreading; block processing; detection; FPGA; implementation; hardware optimization Summary In this paper, a novel MIMO-OFDM transmission scheme is developed to effectively enable multi-access by joint code design across multiple antennas, subcarriers, OFDM frames, and users. It achieves better spectrum efficiency while improving bit error rate performance. The proposed scheme uses either parity bit selected or permutation techniques to assign spreading codes at the transmitter side. As a result, the detection at the receiver is greatly improved because of the fact that identifying the spreading code(s) directly yields the transmitted data symbols. The paper also investigates the field-programmable gate array implementation of the proposed algorithms; optimization techniques are proposed to reduce area, power, and time. These techniques include a pipelined architecture for inverse FFT/FFT blocks, an efficient low complexity algorithm for despreading based on counters and comparators and an optimized architecture for complex matrix inversion using Gauss-Jordan elimination (GJ-elimination). Finally, the fixed-point optimized field-programmable gate array architecture for MIMO-OFDM transceiver is developed, where the maximum allowed performance loss because of quantization is defined, the tradeoffs between BER performance and area reduction are investigated.

Rapid prototyping

Byline: Nancy Wilkins-Diehr, Sandra Gesing, Tamas Kiss, Antonio Tadeu A. Gomes, Bruno F. Bastos, Vivian Medeiros, Vinicius M. Moreira Summary Arguably, an important amount of scientific software development time is likely to be employed on user interfaces. In particular, science gateways have gained increasing interest from the e-Science community. These gateways allow hiding the complexity of the underlying resources that give support to the management of scientific data and to the execution of scientific applications. Based on our previous experience with the development of science gateways for diverse application domains in the Brazilian national high-performance computing network (SINAPAD), we have devised a rapid prototyping strategy to lower the barrier for scientific application developers to launch new science gateways. This strategy is based on two main tools. The first tool implements a gateway engine that can be configured by a small set of XML files. Such files completely define the desired functionality of a specific science gateway in the gateway engine. The gateway engine also offers other features not commonly found in related technologies, such as file sharing, data provenance tracking, and restricted anonymous access to underlying computational resources. The second tool implements both an editor and a packager for the aforementioned engine. This tool allows the developer to rapidly deploy and launch a new science gateway in ordinary Web application containers. In this paper, we present our results with the use of both tools in the SINAPAD network. We also discuss about the current limitations of both tools, as well as how we have been dealing with such limitations to provide a more comprehensive toolset to developers.

Biogenic amines, Microfluidics, Polyamines, Dimethylpolysiloxane, and Rapid prototyping

Keywords: electrochemiluminescence; microfluidics; biogenic amines; tris(2,2'-bipyridyl)ruthenium(II); carbon electrodes Abstract A simple, sensitive, and rapid electrochemiluminescent (ECL) method was developed for the detection of several polyamines on a microfluidic chip. Rapid prototyping of poly(dimethylsiloxane) was used to fabricate flow channels and carbon paste microelectrodes. These devices are easily fabricated and amenable to ECL detection due to their planar and optically transparent nature. The ECL reaction between tris(2,2'-bipyridyl)ruthenium(II) and amine-containing co-reactants was used to generate the ECL signal. Experimental parameters were optimized and low micromolar limits of detection (S/N=3) were determined for four different polyamines. The method was successfully used to determine the concentration of spermine in milk samples.

Sousa (a), Luis Magalhaes (d), Emanuel Peres (a) Keywords Virtual Reality; 360* Videos Editing; Immersive Digital Panoramas; Multimedia; 3D model; 3D text; Spatialized Sound; Prototyping Abstract While VR grows in the range of application contexts -- e.g. entertainment, training, cultural heritage and medicine -- its economic impact is expected to reach around 15bn USD, by the year of 2020. Within VR field, 360* video has been sparking the interest of development and research communities. However, editing tools supporting 360* panoramas are usually expensive and/or demand programming skills and/or advanced user knowledge. Besides, applicational approaches to quickly and intuitively set up such 360* video-based VR environments complemented with diverse types of parameterizable virtual assets and multimedia elements are still hard to find. Thereby, this paper aims to propose a system specification to simply and rapidly configure immersive VR environments composed of surrounding 360* video spheres that can be complemented with parameterizable multimedia contents -- namely 3D models, text and spatial sound --, whose behavior can be either time-range or user-interaction dependent. Moreover, a preliminary prototype that follows a substantial part of the previously mentioned specification and implements the enhancement of 360* videos with time-range dependent virtual assets is presented. Preliminary tests evaluating usability and user satisfaction were also carried out with 30 participants, from which encouraging results were achieved.

Wireless local area networks (WLANs) are currently playing an important role in serving the indoor traffic demand. Therefore, there is a need for software-defined radio platforms (SDRs) that can enable the solutions used in these systems to be tested in real environments as well as simulated results. In this paper, we present the SDR-based wireless receiver platform for determining the real-time WLANs performance and provide the comparison of the different channel estimation methods for IEEE 802.11g based on orthogonal frequency division multiplexing (OFDM) operations. The implementation of the receiver comprises the universal software radio peripheral and National Instruments LabVIEW. To determine the real-time receiver tool performance, we emphasized necessary signal processing techniques and different channel estimation methods with varying experimental parameters in real wireless environments. Experimental results report that the SDR-based receiver tool with the LabVIEW in real-time provides the throughput of the OFDM wireless network. The captured throughput performance concerning frame error rate by the receiver is also scrutinized with different channel estimation methods. Byline: Kerem Kucuk

Management science -- Measurement and Rapid prototyping -- Measurement

We propose a platform for the rapid prototyping of active measurement tools to collect network characteristics. Our proposal, named FLAME (Flexible Lightweight Active Measurement Environment), allows the prototyping of active measurement tools that depend or not on cooperative destination nodes. FLAME provides its users with basic active measurement primitives -- corresponding to basic building blocks -- upon which sophisticated active measurement tools can be prototyped quickly, practically, and efficiently through scripts in the Lua scripting language. This platform is based on the distributed deployment of measurement agents in some network nodes. These agents can send and receive probes in response to Lua scripts sent by a user console. Such agents also publish the measurement data in a standardized way in a repository that a central manager keeps, thus simplifying the management and analysis of such data. We validate the FLAME platform as well as show its flexibility and accuracy through experiments on a local testbed and also on Planet-lab. We also evaluate the proposed platform as compared to previous work in terms of the easing of development due to prototype scripting as well as the achieved memory footprint. In conclusion, we discuss different possibilities for further developments built upon the basic functionality of the proposed platform.

Keywords Rework; Corrective Iteration; Firefighting; Negative Iteration; Product Development; System Engineering Abstract Given the need to develop a systems engineering framework to enable rapid prototyping and rapid fielding capability for the U.S. Department of Defense (DOD) per Public Law 114-92 and the fact that historically rework has been a problem during product development, a literature survey of engineering and design rework was conducted to better understand its nature and causes. The intent of the survey is to present the current state of research in the understanding of this aspect of development and to articulate future research areas for developing a systems engineering framework during the Technology Maturation and Risk Reduction (TMRR) phase of the DOD life cycle that addresses rework concerns, accelerates iteration and enables rapid prototyping. Since much of the research on rework has been done on information exchange and organizational structure there is a need for future research in systems engineering to develop frameworks to: 1) mitigate the impact of information uncertainty and instability, 2) accelerate information evolution, and 3) reuse knowledge for engineering reasoning.

Additionally, they got the capability to run the complex image processing algorithms on application level, which increases the prototyping speed considerably for 2D barcode implementation. In order to reduce the algorithm complexity further, different techniques have been devised on hardware level such as light conditioning and orientation, placement of barcode and distance from the camera. The system has been effectively deployed for the decoding of PDF 417 codes on student university cards at the university. [c] 2015 Wiley Periodicals, Inc.

Technology application

Today, technology allows us to produce extensive multimodal systems which are totally under human control. These systems are equipped with multimodal interfaces, which enable more natural and more efficient interaction between man and machine. End users can take advantage of natural modalities (e.g. audio, eye gaze, speech, gestures, etc.) to communicate or exchange information with applications. In this work, we assume that a number of these modalities are available to the user. In this paper, we present a prototype of a multimodal architecture, and show how modality selection and fission algorithms are implemented in such a system. We use a pattern technique to divide a complex command into elementary subtasks and select suitable modalities for each of them. We integrate a context-based method using a Bayesian network to resolve ambiguous or uncertain situations. Index terms: Multimodality, Ontology, Bayesian Network, Pattern, User Interface, Multimodal Fission.

Frantz Rapid application prototyping (RAP) is recommended to obtain quick feedback from clients, allowing the validation of software requirements before acceptance tests. In this regard, model-driven engineering (MDE) and agile methods are two important approaches that suggest the use of techniques for RAP. Some fundamental differences between them exist: MDE focuses on software reuse through annotated system models while agile methods recommend the use simpler models to achieve quick feedback from clients. In order to comply with agility principles but still concerned about the future reuse of the developed software, the quick design of annotated models must be considered. This paper presents a MDE-based RAP methodology and tool support to quickly generate web front ends and models based on the MVC architectural pattern. In addition, we report a case study that has joined MDE and Scrum by applying our methodology and tool support for complete development of web information system in a Scrum-based industrial software project. We also present lessons learnt from the case study and point out some issues for future research in software engineering to facilitate the introduction of MDE in target contexts.

Programmable logic array and Digital integrated circuits

Performance evaluation of parallel software and architectural exploration of innovative hardware support face a common challenge with emerging manycore platforms: they are limited by the slow running time and the low accuracy of software simulators. Manycore FPGA prototypes are difficult to build, but they offer great rewards. Software running on such prototypes runs orders of magnitude faster than current simulators. Moreover, researchers gain significant architectural insight during the modeling process. We use the Formic FPGA prototyping board [1], which specifically targets scalable and cost-efficient multi-board prototyping, to build and test a 64-board model of a 512-core, MicroBlaze-based, non-coherent hardware prototype with a full network-on-chip in a 3D-mesh topology. We expand the hardware architecture to include the ARM Versatile Express platforms and build a 520-core heterogeneous prototype of 8 Cortex-A9 cores and 512 MicroBlaze cores. We then develop an MPI library for the prototype and evaluate it extensively using several bare-metal and MPI benchmarks. We find that our processor prototype is highly scalable, models faithfully single-chip multicore architectures, and is a very efficient platform for parallel programming research, being 50,000 times faster than software simulation.

Our aim was to develop a sustainable designerly learning through authentic making activities. In this article, we describe the history of this attempt along with our motivations, with an instrumental approach, i.e., through a description of the activities mediated by the artifacts we have prototyped with the schoolteacher and the pupils. First, we explain what we mean by designerly learning, which refers to making activities with a Cultural Historical Activity Theory (CHAT) perspective, extending the focus of making beyond digital literacy and digital fabrication. Then, we describe our prototypes: a series of artifacts, which sets conditions for pupils to engage in classroom's making activities, and for the teacher to facilitate them. Finally, we discuss how such conditions can help scaffold and structure authentic making activities in a classroom context, and therefore designing these conditions might be a prime means to foster a transition toward a designerly learning in public schools.

Electromagnetic fields, Antennas (Electronics), Wireless sensor networks, and Rapid prototyping

Keywords: metallization; radio frequency performance; SLA reflector; three-dimensional printed Abstract A novel high precision and lightweight reflector antenna is proposed. The fabrication process of the reflector adopted Stereo Lithography Apparatus (SLA) printed and metallization. The proposed SLA Reflector (SLAR) antenna structure adopts three-dimensional-printed, which can design complex geometric shapes flexibly and rapid prototyping. That is a good substitute for the traditional method of millimeter wave reflector processing. In order to realize radio frequency (RF) characteristics perfectly, the metallization process of photosensitive resin was elaborated, which realized by first electroless nickel plating, then copper electroplating, and finally chromium electroplating on the protective layer. For verification, the designed reflector antenna was manufactured and measured. The reflectivity of SLAR was measured well by the bow method, which validates excellent fabrication accuracy and reliability. The gain and pattern were measured in the anechoic chamber. The results show that the proposed reflector antenna achieves the gain of 25dBi and the 3dB gain bandwidth of 43% over the full Ka-band. A good agreement can be observed between measurement and simulation.

Computer-Aided Design, Rapid Prototyping, New Technique, Models, Prototypes, Engineering -- Design and construction, and Computer industry -- Product information

Companies can produce a prototype from a computer-aided design (CAD) file within one or two days by using the services of one of the approximately 40 rapid prototyping (RP) service bureaus. The CAD system must interface with the RP equipment, the file format being particularly important. An STL file interfaces with most RP systems and can be created with a good CAD system. Alternatively, many software developers now offer STL translators. STL translators can be created only for solid-model CAD systems only, rather than for models that do not close. Surface models work only if they are designed to be watertight. Additionally, supports must be created for any cantilevers or other unsupported structures to develop a CAD model and it is often appropriate to allow the RP service bureau to create the supports themselves. Future alternatives to the STL format will allow users to create smooth, precise surfaces.

Rapid Prototyping, Distributed Systems, Programming Management, Computer Science, and Programming management (Computers) -- Methods

The development of a distributed program is not an easy task. In this paper, we present a set of rapid prototyping tools that can efficiently help the development process of remote procedure call (RPC)-based programs. After some introduction in the first section, we describe the structure of our prototyping tools in the second section. The tool-set consists of three generators: the distributed frame generator, the user interface generator, and the application model generator. Three sections are devoted to describing these generators. The last part of our paper presents a prototyping example using our tool-set and summarizes the paper.

Rapid Prototyping, Service Bureaus, CAD/CAM, Tutorial, and CAD-CAM systems -- Usage

A business can use a rapid prototyping (RP) service bureau instead of buying a RP system, which can cost anywhere from $50,000 to $550,000. The service bureau can not only act as a supplier but can also serve as an active consultant to the design process. A business needs to receive a job cost estimate first from the RP service bureau, providing all necessary design specifications such as tolerances and product use. The best way to transfer computer-aided files to the service bureau is to use the STL file protocol because it is recognized as the standard for hooking RP machines to computer-aided design systems. The cost of using a service bureau depends on the time it takes to convert data, the time to actually build the part on the RP system and the amount of time it takes to detail the finished product. One disadvantage of the system is a lack of security surrounding the product design even when nondisclosure agreements have been signed. The best use of a rapid prototyping system is when it builds complex parts. A directory of RP service bureaus is included.

When evaluating rapid prototyping systems it is important to measure the accuracy of the process, as well as the safety and durability of materials. Additionally, it is important to consider the cost of installation, training and maintenance. Chrysler's Jeep and Truck Engineering unit decided to produce a single automobile part on five rapid prototyping systems in order to compare them. Chrysler sent an STL of the speedometer adaptor to five companies: DTM, Cubital, Stratasys, Helisys and 3D Systems. Detailed is an overview of the comparisons between the five systems. Areas discussed include quality quantifications, price parameters, and the benchmark bottom line. Skill and experience of the operator can have a significant effect on the accuracy of the part produced.

Ageneralized architecture for signal processing, the wafer scale integration architecture for rapid prototyping (WARP), consists of the universal multiply-substract-add (UMSA) cell and the universal nonlinear (UNL) cell. The class of algorithms is broadened by the WARP architecture, using a single rapid-prototyping architecture. FIR filtering algorithms, FFT computation algorithms and L-U decomposition algorithms can be implemented. The high degree of regularity in signal processing algorithms makes them suitable for wafer scale integration (WSI). Mapping of the algorithm to an array of just a few types of cells on the wafer is facilitated. Careful test planning and strict adherence to design-for-test practices are important to testing WSI circuits. The UMSA and UNL cells are discussed in detail with the mapping of the FFT and L-U decomposition algorithms.

The number of embedded systems in the IoT increases steadily and specialists should be able to implement it faster, without losing any quality level. Current research introduces a way to develop a system using ready-made components, configuring and integrating them among themselves, via high level API. These components represent different parts of distributed embedded system, such as control programs, communication nodes, web applications etc. Our approach presents the easy-to-understand development process, used to support students in learning of embedded systems as a part of IoT.
