In connection with the growing tension and responsibility of the activities of professional operators, it is necessary to improve the means and methods of their medical and psychophysiological support. Purpose — assessment of the effect of combined physiotherapeutic procedures — CPP (contrasting thermal effects, vibratory massage of the spine and feet, aromatherapy, music therapy) with and without transcranial electrostimulation (TES) on the psychophysiological status and working capacity of operators. Materials and methods. Surveyed 26 professional operators (male) aged 27– 38 years, divided into 2 equal in size groups: the main (MG) and control (CG). All the examined individuals were used the CPP base complex, implemented in a physiotherapy capsule. The complex consisted of 14 daily 45-minute CPP in standard mode. For the MG, the 35-minute TES procedures, also performed in standard mode, were additionally included in the base complex. Prior to the appointment of correctional complexes and after their completion, the subjects were tested for sensorimotor qualities and operator performance. Results. The use of correctional complexes in both groups resulted in positive changes in psychophysiological qualities (acceleration of sensorimotor reactions, reduction in hand tremor) and operator performance (increased attention stability, amount of random access memory, improvement of mental operations). However, in the MG, the identified changes were more pronounced: the level of tremor in this group decreased by 13–14% compared with the baseline, while in the CG — only by 6–7% (p=0,037); the time of the complex sensorimotor reaction decreased on average by 5,1%, in the CG — by 3,8% (p=0,049); the integral indicator of operator’s working capacity in the MG increased on average by 10.8%, in the CG — by 7,7% (p=0,039). Conclusion. The developed correctional complex with the inclusion of TES is a highly effective and safe non-pharmacological technology of emergency optimization of psychophysiological qualities and working capacity of operators.

Brain–computer interfaces (BCI) are a type of assistive technology that uses the brain signals of users to establish a communication and control channel between them and an external device. BCI systems may be a suitable tool to restore communication skills in severely motor-disabled patients, as BCI do not rely on muscular control. The loss of communication is one of the most negative consequences reported by such patients. This paper presents a BCI system focused on the control of four mainstream messaging applications running in a smartphone: WhatsApp, Telegram, e-mail and short message service (SMS). The control of the BCI is achieved through the well-known visual P300 row-column paradigm (RCP), allowing the user to select control commands as well as spelling characters. For the control of the smartphone, the system sends synthesized voice commands that are interpreted by a virtual assistant running in the smartphone. Four tasks related to the four mentioned messaging services were tested with 15 healthy volunteers, most of whom were able to accomplish the tasks, which included sending free text e-mails to an address proposed by the subjects themselves. The online performance results obtained, as well as the results of subjective questionnaires, support the viability of the proposed system.

A new silicon detector was designed by the CDF collaboration for Run IIb of the Tevatron at Fermilab. The main building block of the new detector is a "supermodule" or "stave", an innovative, compact and lightweight structure of several readout hybrids and sensors with a bus cable running directly underneath the sensors to carry power, data, and control signals to and from the hybrids. The hybrids use a new, radiation-hard readout chip, the SVX4 chip. A number of SVX4 chips, readout hybrids, sensors, and supermodules were produced and tested in preproduction. The performance (including radiation-hardness) and yield of these components met or exceeded all design goals. The detector design goals, solutions, and performance results are presented.

The increased use of Multilayer Ceramic Capacitors in both chip and encapsulated formats is mainly due to their excellence at decoupling Integrated Circuit Random Access Memories.As a result of this excellent performance, large volumes of this type of capacitor are currently used and indications are that further increases in volume will continue over the next decade. There is therefore a market requirement for continued improvements in performance, reliability and cost.There have been major processing changes for cost reduction reasons, which have resulted in new dielectric systems, changes in electrode types and greatly reduced dielectric thicknesses.Studies of the failure mechanisms in these capacitors have been made, and this paper outlines the effect of process and materials on the reliability of these capacitors.In addition, critical process stages are highlighted and control levels indicated. Some new work on testing techniques and its relevance to delaminations is also reported.

This research proposes control method to balance and stabilize an inverted pendulum. A robust control was analyzed and adjusted to the model output with real time feedback. The feedback was obtained using state space equation of the feedback controller. A linear quadratic regulator (LQR) model tuning and control was applied to the inverted pendulum using internet of things (IoT). The system's conditions and performance could be monitored and controlled via personal computer (PC) and mobile phone. Finally, the inverted pendulum was able to be controlled using the LQR controller and the IoT communication developed will monitor to check the all conditions and performance results as well as help the inverted pendulum improved various operations of IoT control is discussed.

The study assessed whether experimentally induced learned helplessness on a cognitive training task generalized to a situationally dissimilar social interaction test task. Subjects were randomly assigned to non-contingent feedback, contingent feedback and control groups. The non-contingent feedback group demonstrated increased levels of affect (Anxiety. Depression and Hostility) following the training phase, indicating a successful helplessness induction. However, no significant differences were observed between the groups on the subsequent test task, showing that helplessness failed to generalize. A time delay between the test and training phase did not affect the performance of the non-contingent group, although there was an unexpected main effect with all subjects who experienced the delay showing facilitated performance. Results are discussed in terms of the reformulated learned helplessness model and extensions to it.

As military systems become more advanced, more capable, and more sophisticated, they often become more complex. Of primary concern to the human factors specialist is the development of advanced control and display concepts, and application of reasonable tradeoff studies which will guide, if not drive the assessment of these concepts. Similarly, when confronted with conflicting standards and specifications, the human factors engineer must be able to effectively reconcile these discrepancies. Generally the issues pit system constraints (i.e., complexity and development and/or life cycle costs) against operator performance requirements or criteria. The principal objective of this paper is to identify and detail human factors issues requiring consideration when developing command and control concepts for advanced armored military vehicles within the Army's MANPRINT initiative. This paper draws on the authors' experience and expertise in the design and development of armored vehicles to point out the tradeoff considerations and processes necessary in designing complex military systems.
