The new technologies proposed and/or retrofitted into Navy crewstations have demonstrated increasing sophistication and flexibility. Additionally, the crewstation technologies have shown very rapid development cycles. The current approach of reliance solely on flight testing has proven inadequate because of the multitude of equipment operating modes, lack of experimental control of situational variables, possible location/placement of components, variety of operational environments, dynamic crew tasking, and control/display technology unique characteristics. Test methods and relevent criteria are lacking. A quick fix is the use of low fidelity mockups for rapid testing and methods development. Such an approach can be both effective with respect to test dollars and responsive to the dynamics of the control/display development cycle. The present paper discusses the use of the low fidelity simulation in two specific developments. The first example presents the design of formats for a universal control/display layout to be used as a replacement for conventional pushbutton technology. The second example presents testing designed to determine the amount and type of control/display required for a crewstation functional upgrade. Both examples are from the test and evaluation work being performed on Navy patrol aircraft. Finally, a laboratory will be described which is being developed to permit this approach to testing.

Antibody ribosome display remains one of the most successful in vitro selection technologies for antibodies fifteen years after it was developed. The unique possibility of direct generation of whole proteins, particularly single-chain antibody fragments (scFvs), has facilitated the establishment of this technology as one of the foremost antibody production methods. Ribosome display has become a vital tool for efficient and low-cost production of antibodies for diagnostics due to its advantageous ability to screen large libraries and generate binders of high affinity. The remarkable flexibility of this method enables its applicability to various platforms. This review focuses on the applications of ribosome display technology in biomedical and agricultural fields in the generation of recombinant scFvs for disease diagnostics and control.

Project 8 is applying a novel spectroscopy technique to make a precision measurement of the tritium beta-decay spectrum, resulting in either a measurement of or further constraint on the effective mass of the electron antineutrino. ADMX is operating an axion haloscope to scan the mass-coupling parameter space in search of dark matter axions. Both collaborations are executing medium-scale experiments, where stable operations last for three to nine months and the same system is used for development and testing between periods of operation. It is also increasingly common to use low-cost computing elements, such as the Raspberry Pi, to integrate computing and control with custom instrumentation and hardware. This leads to situations where it is necessary to support software deployment to heterogeneous architectures on rapid development cycles while maintaining high availability. Here we present the use of docker containers to standardize packaging and execution of control software for both experiments and the use of kubernetes for management and monitoring of container deployment in an active research and development environment. We also discuss the advantages over more traditional approaches employed by experiments at this scale, such as detached user execution or custom control shell scripts.

Effective Transmission

The last decade has seen many new measurement and control techniques developed. This has been principally due to the development of low cost electronic circuits and, more recently, the microprocessor. As a result of this rapid development the instrument and process control engineer is faced with the arduous task of interfacing new and old equipment with differing transmission and communication requirements. The situation is further complicated by the numerous transmission and communication techniques that are available and the usual dogma of finding differing communication interfaces at either end of the connecting cable. This paper provides an insight to the array of transmission and communication techniques currently in use and looks at new techniques which are being developed. The application of the transmission and communication techniques to process control systems is a subject which is now under careful scrutiny as the establishment of an effective transmission and communication configuration can result in an appreciable cost advantage and increased transmission efficiency. A number of these configurations (networks) are discussed.

With the rapid development of the Internet, the remote control technology was demanded more. In this paper, we designed a simple and practical remote intelligent control system, using CGI technology to complete the construction of Web servers and embedding uCOSII as the real-time operating system in Cortex-M3 core processor. By porting TCP/IP protocol stack, users could login in the server to access and control the system via the Internet. Using NRF2401 wireless technology to build a terminal network, the terminal carried out intelligent control with field data collected by sensors. Meanwhile, users could make monitor and control on a control terminal via a Web browser on a PC or mobile. The remote intelligent control system was stable, real-time, low cost, fit for the smart home, industrial remote monitor and so on, so it would have a better application prospects.

Path Extraction

The necessity for intelligent welding robots that meet the demand in real industrial production, according to the objectives of Industry 4.0, has been supported owing to the rapid development of computer vision and the use of new technologies. To improve the efficiency in weld location for industrial robots, this work focuses on trajectory extraction based on color features identification on three-dimensional surfaces acquired with a depth-RGB sensor. The system is planned to be used with a low-cost Intel RealSense D435 sensor for the reconstruction of 3D models based on stereo vision and the built-in color sensor to quickly identify the objective trajectory, since the parts to be welded are previously marked with different colors, indicating the locations of the welding trajectories to be followed. This work focuses on 3D color segmentation with which the points of the target trajectory are segmented by color thresholds in HSV color space and a spline cubic interpolation algorithm is implemented to obtain a smooth trajectory. Experimental results have shown that the RMSE error for V-type butt joint path extraction was under 1.1 mm and below 0.6 mm for a straight butt joint; in addition, the system seems to be suitable for welding beads of various shapes.

Until recently the set of “model” species used commonly for cell biology was limited to a small number of well-understood organisms, and developing a new model was prohibitively expensive or time-consuming. With the current rapid advances in technology, in particular low-cost high-throughput sequencing, it is now possible to develop molecular resources fairly rapidly. Wider sampling of biological diversity can only accelerate progress in addressing cellular mechanisms and shed light on how they are adapted to varied physiological contexts. Here we illustrate how historical knowledge and new technologies can reveal the potential of nonconventional organisms, and we suggest guidelines for selecting new experimental models. We also present examples of nonstandard marine metazoan model species that have made important contributions to our understanding of biological processes.

Abstract Absolute rotary angular /position sensors play an important role in various applications and rapid development of new technologies requires further accurate measurement and control. In this paper, a novel, very simple, low-cost and high accurate absolute rotary angular/ position sensor is presented. The sensor operation is based on the combination of circular gradient gray scale and gray code pattern. A simple experiment is done in order to demonstrate proof of concept of proposed sensor. The experimental results show that the proposed absolute rotary angular/position sensor has excellent linear characteristics with accuracy below ±1° and resolution of 0.1° within the full measurement range from 0° to 360°. The proposed idea and experimental results can be helpful to design absolute rotary angular/position sensor to improve performance of it.

The success of small satellites has lead to the study of new technologies for the realization of Nano and Micro Launch Vehicle (NMLV) in order to make competitive launch costs. The paper has the objective to define and experimentally investigate the performance of a communication system for NMLV interconnecting the End Systems as On-Board Computer (OBC), telemetry apparatus, Navigation Unit...we propose a low cost Ethernet-based solution able to provide the devices with high interconnection bandwidth. To guarantee hard delays to the Guide, Navigation and Control applications we propose some architectural changes of the traditional Ethernet network with the introduction of a layer implemented in the End Systems and allow for the lack of any contention on the network links. We show how the proposed solution has comparable performance to the one of TTEthernet standard that is a very expensive solution. An experimental test-bed equipped with Ethernet switches and Hercules boards by Texas Instruments is also provided to prove the feasibility of the proposed solution.

The world population is expected to grow by another two billion in 2050, according to the survey taken by the Food and Agriculture Organization, while the arable area is likely to grow only by 5%. Therefore, smart and efficient farming techniques are necessary to improve agriculture productivity. Agriculture land suitability assessment is one of the essential tools for agriculture development. Several new technologies and innovations are being implemented in agriculture as an alternative to collect and process farm information. The rapid development of wireless sensor networks has triggered the design of low-cost and small sensor devices with the Internet of Things (IoT) empowered as a feasible tool for automating and decision-making in the domain of agriculture. This research proposes an expert system by integrating sensor networks with Artificial Intelligence systems such as neural networks and Multi-Layer Perceptron (MLP) for the assessment of agriculture land suitability. This proposed system will help the farmers to assess the agriculture land for cultivation in terms of four decision classes, namely more suitable, suitable, moderately suitable, and unsuitable. This assessment is determined based on the input collected from the various sensor devices, which are used for training the system. The results obtained using MLP with four hidden layers is found to be effective for the multiclass classification system when compared to the other existing model. This trained model will be used for evaluating future assessments and classifying the land after every cultivation.

This review focuses on DNA and RNA vaccines whose potential use was first considered at the end of the 20th century. However, not a single bacterial plasmid-based or mRNA vaccine has been used since that time in public healthcare for the prevention of infectious diseases. Nevertheless, vaccines containing recombinant nucleic acids as the active ingredient still attract interest due to the possibility of rapid development, low-cost production, safety of the technology and the potential to activate cellular and humoral immunity. Recent technological advances have largely overcome the problems of low immunogenicity, instability, and difficulties with the delivery of DNA and RNA vaccines in humans. The aim of this review was to present the main strategies of development of DNA and RNA vaccines designed to prevent infectious diseases, and to summarise requirements for the quality control and preclinical studies. The article examines the general principles of creation of plasmid vectors encoding protective antigens. It describes new technologies used in the creation of DNA vaccines with plasmids encoding an attenuated virus genome (iDNA and PPLAV), and RNA vaccines based on mRNA and self-amplifying RNAs. The article presents current regulatory requirements for the choice of quality parameters to be tested and the general principles of preclinical studies of DNA and RNA vaccines.
