It is shown that for the pro­ces­sing of in­tensi­ve da­ta flows in in­dustry (ma­na­ge­ment of techno­lo­gi­cal pro­ces­ses and complex ob­jects), energy (op­ti­mi­za­ti­on of lo­ad in po­wer grids), mi­li­tary af­fa­irs (techni­cal vi­si­on, mo­bi­le ro­bot traf­fic control, cryptog­raphic da­ta pro­tec­ti­on), transport (traf­fic ma­na­ge­ment and en­gi­ne), me­di­ci­ne (di­se­ase di­ag­no­sis) and instru­men­ta­ti­on (pat­tern re­cog­ni­ti­on and control op­ti­mi­za­ti­on) the re­al-ti­me hardwa­re neu­ral net­works with high ef­fi­ci­ency of eq­uipment use sho­uld be appli­ed. The ope­ra­ti­onal ba­sis of neu­ral net­works is for­med and the fol­lo­wing ope­ra­ti­ons are cho­sen for hardwa­re imple­men­ta­ti­on: the se­arch of the ma­xi­mum and mi­ni­mum val­ues, cal­cu­la­ti­on of the sum of squa­res of dif­fe­ren­ces and sca­lar pro­duct. Req­ui­re­ments for hardwa­re com­po­nents of neu­ral net­works with co­or­di­na­ted ver­ti­cal-pa­ral­lel da­ta pro­ces­sing are de­ter­mi­ned, the ma­in ones of which are: high ef­fi­ci­ency of eq­uipment use, adap­ta­ti­on to the req­ui­re­ments of spe­ci­fic appli­ca­ti­ons, co­or­di­na­ti­on of in­put da­ta in­tensity with the com­pu­ta­ti­on in­tensity in hardwa­re com­po­nent, re­al-ti­me ope­ra­ti­on, struc­tu­ral fo­cus on VLSI imple­men­ta­ti­on, low de­ve­lop­ment ti­me and low cost. It is sug­gested to eval­ua­te the de­ve­lo­ped hardwa­re com­po­nents of neu­ral net­works ac­cording to the ef­fi­ci­ency of the eq­uipment use, ta­king in­to ac­co­unt the comple­xity of the com­po­nent imple­men­ta­ti­on al­go­rithm, the num­ber of ex­ternal in­terfa­ce pins, the ho­mo­ge­ne­ity of the com­po­nent struc­tu­re and re­la­ti­onship of the ti­me of ba­sic neu­ro-ope­ra­ti­on with the eq­uipment costs. The ma­in ways to control the in­tensity of cal­cu­la­ti­ons in hardwa­re com­po­nents are the cho­ice of the num­ber and bit ra­tes of da­ta pro­ces­sing paths, chan­ging the du­ra­ti­on of the work cycle by cho­osing the spe­ed of the ele­ment ba­se and the comple­xity of ope­ra­ti­ons imple­men­ted by the con­ve­yor. The pa­ral­lel ver­ti­cal-gro­up da­ta pro­ces­sing met­hods are pro­po­sed for the imple­men­ta­ti­on of hardwa­re com­po­nents of neu­ral net­works with co­or­di­na­ted pa­ral­lel-ver­ti­cal control pro­ces­sing, they pro­vi­de control of com­pu­ta­ti­onal in­tensity, re­duc­ti­on of hardwa­re costs and VLSI imple­men­ta­ti­on. A pa­ral­lel ver­ti­cal-gro­up met­hod and struc­tu­re of the com­po­nent of cal­cu­la­ti­on of ma­xi­mum and mi­ni­mum num­bers in ar­rays are de­ve­lo­ped, due to pa­ral­lel pro­ces­sing of a sli­ce from the gro­up of di­gits of all num­bers it pro­vi­des re­duc­ti­on of cal­cu­la­ti­on ti­me ma­inly de­pen­ding on bit si­ze of num­bers. The pa­ral­lel ver­ti­cal-gro­up met­hod and struc­tu­re of the com­po­nent for cal­cu­la­ting the sum of squa­res of dif­fe­ren­ces ha­ve be­en de­ve­lo­ped, due to pa­ral­le­li­za­ti­on and se­lec­ti­on of the num­ber of con­ve­yor steps it en­su­res the co­or­di­na­ti­on of in­put da­ta in­tensity with the cal­cu­la­ti­on in­tensity, re­al-ti­me mo­de and high eq­uipment ef­fi­ci­ency. The pa­ral­lel ver­ti­cal-gro­up met­hod and struc­tu­re of sca­lar pro­duct cal­cu­la­ti­on com­po­nents ha­ve be­en de­ve­lo­ped, the cho­ice of bit pro­ces­sing paths and the num­ber of con­ve­yor steps enab­les the co­or­di­na­ti­on of in­put da­ta in­tensity with cal­cu­la­ti­on in­tensity, re­al-ti­me mo­de and high ef­fi­ci­ency of the eq­uipment. It is shown that the use of the de­ve­lo­ped com­po­nents for the synthe­sis of neu­ral net­works with co­or­di­na­ted ver­ti­cal-pa­ral­lel da­ta pro­ces­sing in re­al ti­me will re­du­ce the ti­me and cost of the­ir imple­men­ta­ti­on.

Emerging heterogeneous computing, computing at the edge, machine learning and AI at the edge technology drives approaches and techniques for processing and analysing onboard instrument data in near real-time. The author has used edge computing and neural networks combined with high performance heterogeneous computing platforms to accelerate AI workloads. Heterogeneous computing hardware used is readily available, low cost, delivers impressive AI performance and can run multiple neural networks in parallel. Collecting, processing and machine learning from onboard instruments data in near real-time is not a trivial problem due to data volumes, complexities of data filtering, data storage and continual learning. Little research has been done on continual machine learning which aims at a higher level of machine intelligence through providing the artificial agents with the ability to learn from a non-stationary and never-ending stream of data. The author has applied the concept of continual learning to building a system that continually learns from actual boat performance and refines predictions previously done using static VPP data. The neural networks used are initially trained using the output from traditional VPP software and continue to learn from actual data collected under real sailing conditions. The author will present the system design, AI, and edge computing techniques used and the approaches he has researched for incremental training to realise continual learning.

The adoption of intelligent systems with Artificial Neural Networks (ANNs) embedded in hardware for real-time applications currently faces a growing demand in fields such as the Internet of Things (IoT) and Machine to Machine (M2M). However, the application of ANNs in this type of system poses a significant challenge due to the high computational power required to process its basic operations. This paper aims to show an implementation strategy of a Multilayer Perceptron (MLP)-type neural network, in a microcontroller (a low-cost, low-power platform). A modular matrix-based MLP with the full classification process was implemented as was the backpropagation training in the microcontroller. The testing and validation were performed through Hardware-In-the-Loop (HIL) of the Mean Squared Error (MSE) of the training process, classification results, and the processing time of each implementation module. The results revealed a linear relationship between the values of the hyperparameters and the processing time required for classification, also the processing time concurs with the required time for many applications in the fields mentioned above. These findings show that this implementation strategy and this platform can be applied successfully in real-time applications that require the capabilities of ANNs.

Abstract The concept of integrating programmable low-cost cameras into the office infrastructure and BMS for real-time, web-based sensing and control of the luminous environment in buildings is presented in this study. Experiments were conducted to evaluate the potential of predicting the luminance field perceived by an office occupant using a programmable calibrated HDR camera installed at the rear side of a computer monitor or on the wall behind the occupant, for a variety of sky conditions and shading options. The generated luminance maps using Python scripts with OpenCV packages were further processed to extract daylighting and glare metrics using Evalgare. The results showed that: (i) among the different camera resolutions that were compared, the 330x330 resolution was selected as the best option to balance between accurate capturing of visual environment and comfort and computational efficiency; (ii) a camera sensor embedded on the rear side of a computer screen could capture interior visual conditions consistently similarly to those viewed by the occupant, except for sunny conditions without proper shading protection. This prototype study paves the way for luminance monitoring and daylight control using programmable low-cost camera sensors embedded into the office infrastructure.

Given the high number of vehicle-crash victims, it has been established as a priority to reduce this figure in the transportation sector. For this reason, many of the recent researches are focused on including control systems in existing vehicles, to improve their stability, comfort and handling. These systems need to know in every moment the behavior of the vehicle (state variables), among others, when the different maneuvers are performed, to actuate by means of the systems in the vehicle (brakes, steering, suspension) and, in this way, to achieve a good behavior. The main problem arises from the lack of ability to directly capture several required dynamic vehicle variables, such as roll angle, from low-cost sensors. Previous studies demonstrate that low-cost sensors can provide data in real-time with the required precision and reliability. Even more, other research works indicate that neural networks are efficient mechanisms to estimate roll angle. Nevertheless, it is necessary to assess that the fusion of data coming from low-cost devices and estimations provided by neural networks can fulfill the reliability and appropriateness requirements for using these technologies to improve overall safety in production vehicles. Because of the increasing of computing power, the reduction of consumption and electric devices size, along with the high variety of communication technologies and networking protocols using Internet have yield to Internet of Things (IoT) development. In order to address this issue, this study has two main goals: 1) Determine the appropriateness and performance of neural networks embedded in low-cost sensors kits to estimate roll angle required to evaluate rollover risk situations. 2) Compare the low-cost control unit devices (Intel Edison and Raspberry Pi 3 Model B), to provide the roll angle estimation with this artificial neural network-based approach. To fulfil these objectives an experimental environment has been set up composed of a van with two set of low-cost kits, one including a Raspberry Pi 3 Model B, low cost Inertial Measurement Unit (BNO055 - 37€) and GPS (Mtk3339 - 53€) and the other having an Intel Edison System on Chip linked to a SparkFun 9 Degrees of Freedom module. This experimental environment will be tested in different maneuvers for comparison purposes. Neural networks embedded in low-cost sensor kits provide roll angle estimations very approximated to real values. Even more, Intel Edison and Raspberry Pi 3 Model B have enough computing capabilities to successfully run roll angle estimation based on neural networks to determine rollover risks situation fulfilling real-time operation restrictions stated for this problem.

Under the influence of novel corona virus pneumonia epidemic prevention and control, it has put forward higher requirements for data storage and processing for personnel management system. The distributed asynchronous data aided computer information interaction system can solve the problem of multi node concurrent data processing. The traditional computer information interaction system has poor real-time performance, low precision and asynchronous data processing ability. The invocation features of message queuing asynchronous caching mode are combined with the standardization of Web services and cross language with cross platform access features in this paper. Through the combination of the two technologies, a flexible and universal asynchronous interaction architecture of distributed system is established. Based on Web service technology and system to system access, the call and response of tasks between modules are carried out in the system, which makes the interaction between the whole system have the characteristics of message driven. The test result shows that the system proposed in this paper has good real-time performance and strong data processing ability. It is suitable for the data interaction of distributed personal management system under the influence of novel corona virus pneumonia epidemic prevention and control.
