Me and AAC - Alternative and Augmented Communication in West Germany from a Biographical and Media Archaeological Perspective

The article presents a case study on the history of Augmentative and Alternative Communication (AAC) in West Germany from the 1980s to the early 2000s, with a regional focus on the state of North Rhine-Westphalia (NRW). The conceptual framework guiding this study is the question of how the meaning and individual experience of assistance evolve in conjunction with the technical development and practical use of speech computers. The article sheds light on the interplay between historical contingency and individual socio-technical situatedness of disabled AAC-users. It brings together two disciplinary perspectives in a dialogue based on interviews, published primary sources, and the description of historical hardware and software. Biographical narratives of AAC users in NRW are combined with a media archaeological case study of the institutional and technological formations and developments of AAC in the region. We discuss assistive technologies as a historically variable phenomenon. Assistance is a precarious undertaking that is constantly renegotiated by new technological developments. Each stage of assistive technology has consequences for everyday communication practices and the provision of communicative assistance, creating possibilities and impossibilities for the use of technology. For AAC users, this means that they find themselves in specific constellations that affect both their relationship with the device and their subjective preferences and established routines. We argue that so-called assistive technologies are involved in the co-constitution of disability, and therefore suggest referring to them as ‘assistive media.’

Dose–Response Curve in REMA Test: Determination from Smartphone-Based Pictures

We report a workflow and a software description for digital image colorimetry aimed at obtaining a quantitative dose–response curve and the minimal inhibitory concentration in the Resazurin Microtiter Assay (REMA) test of the activity of antimycobacterial drugs. The principle of this analysis is based on the newly established correspondence between the intensity of the a* channel of the CIE L*a*b* colour space and the concentration of resorufin produced in the course of this test. The whole procedure can be carried out using free software. It has sufficiently mild requirements for the quality of colour images, which can be taken by a typical smartphone camera. Thus, the approach does not impose additional costs on the medical examination points and is widely accessible. Its efficiency is verified by applying it to the case of two representatives of substituted 2-(quinolin-4-yl) imidazolines. The direct comparison with the data on the indicator’s fluorescence obtained using a commercial microplate reader argues that the proposed approach provides results of the same range of accuracy on the quantitative level. As a result, it would be possible to apply the strategy not only for new low-cost studies but also for expanding databases on drug candidates by quantitatively reprocessing existing data, which were earlier documented by images of microplates but analysed only qualitatively.

Low-cost IoT-Based sensors dashboard for monitoring the state of health of mobile harbor cranes: Hardware and software description

A cost-effective IoT-based real-time data acquisition and analysis hardware system was developed to enhance the performance of the mobile harbor cranes using a combination of a cost-effective quality control monitoring sensor dashboard (proximity sensors, angle position sensor, weight sensor, vibration sensor, and wind sensor), embedded microcontroller (Arduino), and embedded computer (Raspberry Pi). Hardware was operated using a specially developed novel Quality Control and Data Acquisition Multiprocessing software (QC-DAS). The QC-DAS can automatically collect and save real-time data of the sensors in a large-capacity SD card, monitor the state of health of the hardware, and transmit the real-time data of the sensors and the working state of the crane to an IoT server. The novelty of the QC-DAS design is that each function is encapsulated in a predefined module that is "immersed" in a message transmission medium. Modules interact by sending and receiving various signals through this medium. Modularity makes system design simpler, faster, and flexible. Thanks to modularity, users may incorporate their data processing modules when new sensors are added to match the system's needs. Thanks to modularity the DC-DAS can operate quality control hardware for any mobile cranes. There are several constraints in the quality control data acquisition system used by the Damietta Port Authority in Damietta, Egypt, SESCO TRANS company which cause the loading and unloading process to be slowed down. As a result, the SESCO TRANS company upgraded its quality control data acquisition system using the QC-DAS. The hardware was deployed for six months, during which the collected data was used to verify the crane's performance. The vibration produced by the slewing of the crane was monitored and compared with the bearing fault frequency limits, during the operation the wind speed was monitored and compared with the critical wind speed to stop the crane operation automatically, and the payloads data of the six months was collected and was used to calculate the working efficiency of the load and unload process of the crane. The results demonstrated that while maintenance costs were decreased, the crane load/unload procedure was improved. The SESCO TRANS company crane operators approved the developed approach and appreciated the achieved results.

Fluorometer “FLS 10s”

Many biological objects have the ability to fluoresce under the influence of electromagnetic radiation in the optical range. Measuring the fluorescence of a biological object helps obtain information about its internal state. Therefore, the creation of instruments for scientific research in the field of studying biological objects has been a pressing task for many areas of human activity for many years. In particular, these are areas such as agriculture, ecology, food industry and medicine. This article is devoted to a description of the recently developed “FLS 10s” device for studying plant chlorophyll fluorescence, as well as description of software for operating the device and analyzing the information obtained. This device provides data of well known OJIP test. Keywords: fluorescence, fluorometer, fluorescence measurement, Kautsky effect, OJIP test, fluorescence induction, fast chlorophyll α fluorescence induction.

Detection of insulin oligomeric forms by a novel surface plasmon resonance-diffusion coefficient based approach.

Insulin is commonly used to treat diabetes and undergoes aggregation at the site of repeated injections in diabetic patients. Moreover, aggregation is also observed during its industrial production and transport and should be avoided to preserve its bioavailability to correctly adjust glucose levels in diabetic patients. However, monitoring the effect of various parameters (pH, protein concentration, metal ions, etc.) on the insulin aggregation and oligomerization state is very challenging. In this work, we have applied a novel Surface Plasmon Resonance (SPR)-based experimental approach to insulin solutions at various experimental conditions, monitoring how its diffusion coefficient is affected by pH and the presence of metal ions (copper and zinc) with unprecedented sensitivity, precision, and reproducibility. The reported SPR method, hereby applied to a protein for the first time, besides giving insight into the insulin oligomerization and aggregation phenomena, proved to be very robust for determining the diffusion coefficient of any biomolecule. A theoretical background is given together with the software description, specially designed to fit the experimental data. This new way of applying SPR represents an innovation in the bio-sensing field and expanding the potentiality of commonly used SPR instruments well over the canonical investigation of biomolecular interactions.

Software Subclassification Based on BERTopic-BERT-BiLSTM Model

With the continuous influx of application software onto the application software market, achieving accurate software recommendations for users in the huge software application market is urgent. To address this issue, each application software market currently provides its own classification tags. However, several problems still exist, such as the lack of objectivity, hierarchy, and standardization in these classifications, which in turn affects the accuracy of precise software recommendations. Accordingly, a customized BERTopic model is proposed to cluster the software description texts of the application software and the automatic tagging and updating of the application software tags are realized according to the clusters obtained by topic clustering and the extracted subject words. At the same time, a data enhancement method based on the c-TF-IDF algorithm is proposed to solve the problem of imbalance of datasets, and then the classification model based on the BERT-BiLSTM model is trained on the labeled datasets to classify the software in the dimension of the application function, so as to realize the accurate software recommendation for users. Based on the experimental verification of two datasets, 21 categories in the SourceForge dataset and 19 categories in the Chinese App Store dataset are subclassed by the clustering results of the customized BERTopic model, and the tags of 138 subclasses and 262 subclasses are formed, respectively. In addition, a complete tagged software description text dataset is constructed and the software tags are updated automatically. In the first stage of the classification experiment, the weighted average accuracy, recall rate, and F1 value can reach 0.92, 0.91, and 0.92, respectively. In the second stage, the weighted average accuracy, recall rate, and F1 value can all reach 0.96. After data enhancement, the weighted average F1 value of the classification model can be increased by up to two percentage points.

Удаленная работа с комплектом тягового электрооборудования карьерного самосвала

The electromechanical transmission of a mine dump truck is an electrical equipment complex with a set of parameters for setting and status monitoring. To improve the quality and to reduce the time and cost of service maintenance of mine dump trucks, a data transmission system is organized that provides remote work with control system units. Such systems significantly increase the efficiency of operation of mine dump trucks with the integrated use of a standard approach to maintenance and repair of mining equipment and mobile technologies. They allow to identify most of the faults due to the use of a real-time parameter monitoring system during the routine operation of mine truck. The authors have used the methods of design and software architecture, methods of object-oriented programming and development of multi-threaded applications using the high-level programming language C/C++. The paper proposes a functional diagram of data transmission for remote operation with electrical equipment blocks. The description of the instrumental software for monitoring and configuring the parameters of the dump trucks electric transmission is given. A procedure for remote work with a set of traction electrical equipment has been developed. The developed system has been tested at the stages of testing and adjustment. It is used in real operating conditions and allows organizing service maintenance of domestic-made dump trucks at a level that is not inferior to their best imported counterparts. The use of an integrated approach and the extended list of diagnostic parameters of the electric transmission when it is singled out as a separate element of the diagnostic system significantly improves the quality-of-service maintenance of traction electrical equipment.

An investigation of performance and power efficiency for parallax background scrolling hardware written in high-level synthesis

We are developing a game programming software library so that high-level synthesis, HLS, can automatically generate high-performance and low-power hardware modules. A mobile terminal with a user-available reconfigurable device like Field programmable gate array, FPGA, we have proposed will efficiently perform game application built in HLS-oriented game library instead of power-hungry software execution. The dynamic hardware reconfiguration on a single FPGA can execute many kinds of game applications. Our previous research has developed software description methods for two-background scrolling in HLS-oriented game programming library by using two methods. They are (1) Full-parallel equips plural physical ports loading background images individually making HLS hardware execute the entire process parallelly increasing the amount of hardware: (2) Semi-parallel shares the single port loading background images serially, suppressing the hardware growth while achieving moderate performance by overlapping operation phases. We investigate two methods about execution time and power efficiency on the parallax scrolling with 2 to 4 backgrounds. The execution times of full-parallel hardware at 100MHz clock frequency are constantly about 9.65 [ms] while those of semi-parallel are 28, 38 and 47 [ms]. The PC at 3.2 GHz shows 78, 98 and 105 [ms] respectively as well. The power efficiencies about the full-parallel estimated considering hardware enlargement are 167, 208 and 112 times compared to the software execution in the PC, while those of semi-parallel are 94, 88 and 75 times. This fact indicates that the full-parallel is better strategy for parallax background scrolling in this case although more hardware resource are invested.

PROCEDURE OF MULTIDISCIPLINARY AERONAUTICAL ENGINEERING BASED ON AUTOMATED INFORMATION – ANALYTICAL SUPPORT SYSTEM

The article demonstrates both architecture and software of the automated information – analytical support system, intended for implementation of multidisciplinary aeronautical engineering procedure. The system discussed should generate as a first approximation the design of the prospective aircraft, which could be implemented, considering actual scientific and technical level of aeronautical engineering. In case of impossibility to develop aircraft according to corresponding multidisciplinary requirements, basing on accumulated scientific and technical groundwork, it is necessary to determine priority solutions, which could provide development of discussed prospective aircraft.

The article contains also result of developed both methods and software utilization applying to prospective transport aircraft design.

Towards A Standardized Aerial Platform: ICUAS’22 Firefighting Competition

This paper presents an Unmanned Aerial Vehicle (UAV) platform used for the competition held at the International Conference for Unmanned Aircraft Systems 2022 (ICUAS’22). The envisioned scenario in the competition is delivering an extinguishing ball to a fire with a UAV. Driven on that thought, the qualifying round of the competition is organized in a realistic simulation environment. The competitors are required to navigate through a cluttered environment into a free space, where they perform a search for the target and deliver the ball as close as possible to that target. The competition finals were organized as a part of the conference, with the same goal as in the simulation qualifiers. The UAVs used for the competition are prepared and provided by the organizers. A detailed description of the UAV software and hardware is outlined in the paper as a step towards standardizing aerial research platform.

FAIR-Checker: supporting digital resource findability and reuse with Knowledge Graphs and Semantic Web standards

The current rise of Open Science and Reproducibility in the Life Sciences requires the creation of rich, machine-actionable metadata in order to better share and reuse biological digital resources such as datasets, bioinformatics tools, training materials, etc. For this purpose, FAIR principles have been defined for both data and metadata and adopted by large communities, leading to the definition of specific metrics. However, automatic FAIRness assessment is still difficult because computational evaluations frequently require technical expertise and can be time-consuming. As a first step to address these issues, we propose FAIR-Checker, a web-based tool to assess the FAIRness of metadata presented by digital resources. FAIR-Checker offers two main facets: a “Check” module providing a thorough metadata evaluation and recommendations, and an “Inspect” module which assists users in improving metadata quality and therefore the FAIRness of their resource. FAIR-Checker leverages Semantic Web standards and technologies such as SPARQL queries and SHACL constraints to automatically assess FAIR metrics. Users are notified of missing, necessary, or recommended metadata for various resource categories. We evaluate FAIR-Checker in the context of improving the FAIRification of individual resources, through better metadata, as well as analyzing the FAIRness of more than 25 thousand bioinformatics software descriptions.

Анализ эффективности контроллера OpenFlow в сети с разной нагрузкой

One of the main ideas of software-defined network is the creation of special software (OpenFlow controller), which allows you to separate the management of existing network equipment (routers and switches) without changing it. This software can run on a separate PC, which is managed by a network administrator. Therefore, this paper examines the performance of the OpenFlow controller. This article describes the OpenFlow OpenDaylight controller, and also defines its place in the network architecture of a software-defined network. The methodology of the conducted research of the experiment includes a description of the special Cbench software. In operation, Cbench was launched in two modes: the delay mode for sending subsequent packets and the maximum data transfer mode for measuring bandwidth. In delay mode, each switch sends one new packet to the emulated stream and waits for a response. After that, it sends the next packet and so on. The delay shows the time it takes for the controller to process an OpenFlow request under low load. In bandwidth mode, each switch sends requests until the buffer is full. Thus, this mode allows you to measure the maximum performance that the controller can handle. According to the presented methodology, experimental samples of the network were collected. The experiments are as follows: 1) when the switch distributes the load to the controllers and, 2) Cbench generates streams for each of the controllers separately. The mode of operation of the Cbench program is also changing. According to the results of the experiments, data is obtained on the number of packets processed by each controller under different conditions.

Pdif-mediated antibiotic resistance genes transfer in bacteria identified by pdifFinder.

Modules consisting of antibiotic resistance genes (ARGs) flanked by inverted repeat Xer-specific recombination sites were thought to be mobile genetic elements that promote horizontal transmission. Less frequently, the presence of mobile modules in plasmids, which facilitate a pdif-mediated ARGs transfer, has been reported. Here, numerous ARGs and toxin-antitoxin genes have been found in pdif site pairs. However, the mechanisms underlying this apparent genetic mobility is currently not understood, and the studies relating to pdif-mediated ARGs transfer onto most bacterial genera are lacking. We developed the web server pdifFinder based on an algorithm called PdifSM that allows the prediction of diverse pdif-ARGs modules in bacterial genomes. Using test set consisting of almost 32 thousand plasmids from 717 species, PdifSM identified 481 plasmids from various bacteria containing pdif sites with ARGs. We found 28-bp-long elements from different genera with clear base preferences. The data we obtained indicate that XerCD-dif site-specific recombination mechanism may have evolutionary adapted to facilitate the pdif-mediated ARGs transfer. Through multiple sequence alignment and evolutionary analyses of duplicated pdif-ARGs modules, we discovered that pdif sites allow an interspecies transfer of ARGs but also across different genera. Mutations in pdif sites generate diverse arrays of modules which mediate multidrug-resistance, as these contain variable numbers of diverse ARGs, insertion sequences and other functional genes. The identification of pdif-ARGs modules and studies focused on the mechanism of ARGs co-transfer will help us to understand and possibly allow controlling the spread of MDR bacteria in clinical settings. The pdifFinder code, standalone software package and description with tutorials are available at https://github.com/mjshao06/pdifFinder.

Emulation of epidemics via Bluetooth-based virtual safe virus spread: Experimental setup, software, and data.

We describe an experimental setup and a currently running experiment for evaluating how physical interactions over time and between individuals affect the spread of epidemics. Our experiment involves the voluntary use of the Safe Blues Android app by participants at The University of Auckland (UoA) City Campus in New Zealand. The app spreads multiple virtual safe virus strands via Bluetooth depending on the physical proximity of the subjects. The evolution of the virtual epidemics is recorded as they spread through the population. The data is presented as a real-time (and historical) dashboard. A simulation model is applied to calibrate strand parameters. Participants' locations are not recorded, but participants are rewarded based on the duration of participation within a geofenced area, and aggregate participation numbers serve as part of the data. The 2021 experimental data is available as an open-source anonymized dataset, and once the experiment is complete, the remaining data will be made available. This paper outlines the experimental setup, software, subject-recruitment practices, ethical considerations, and dataset description. The paper also highlights current experimental results in view of the lockdown that started in New Zealand at 23:59 on August 17, 2021. The experiment was initially planned in the New Zealand environment, expected to be free of COVID and lockdowns after 2020. However, a COVID Delta strain lockdown shuffled the cards and the experiment is currently extended into 2022.
