COMMUNICATION IN AI-ASSISTED TEAMS DURING AN INTERDISCIPLINARY DRONE DESIGN PROBLEM

Human-artificial intelligent (AI) - assisted teaming is becoming a strategy for coalescing the complementary strengths of humans and computers to solve difficult tasks. Yet, there is still much to learn regarding how the integration of humans with AI agents into a team affects human behavior. Accordingly, this work begins to inform this research gap by focusing specifically on how the communication structure and interaction changes within AI-assisted human teams. The underlying discourse data for this work originates from a prior research study in which teams solve an interdisciplinary drone design and path-planning problem. Several metrics are employed in this work to study team discourse, including count, diversity, content richness, and semantic coherence. Results show significant differences in communication behavior in AI-assisted teams including more diversity and frequency in communication, more exchange of information regarding principal design parameters and problem-solving strategies, and more cohesion. Overall, this work takes meaningful steps towards understanding the effects of AI agents on human behavior in teams, critical for fully building effective human-AI hybrid teams in the future.

Switched Capacitor Compensation of Supply Distortion in Class-D Amplifiers

This paper presents a switched capacitor technique for bus-pumping compensation in a half-bridge class-D amplifier. The proposed approach, in addition to the almost complete reduction of the bus-pumping effect, allows the half-bridge class-D amplifier to preserve maximum energy efficiency. The studied hardware implementation of the proposed technique demonstrates its advantages of high efficiency, simple circuit, and low cost. The principal design and operating principles are analyzed and described. The experimental static characteristics and time-domain waveforms for the proposed technique are shown to verify its feasibility.

Ventilation of engine rooms in diesel engines ships

"Engines room are equipped with a ventilation system which should provide fresh air for combustion and for removing the heat radiated by main engines, auxiliary engines, boilers, generators and other hot equipment installed in compartment. The paper presents the main requirements, recommendations and challenges regarding designing and construction of the ventilation system. The principal design aspects highlighted in this material are related to reducing the pressure drop across the distribution system to reduce the energy used by the fan to blow the air inside the room and to identify the best arrangement of air distribution inlet/outlet in order to get high efficiency of the cooling air."

Landing efficiency control of a six-degree-of-freedom aircraft model with magnetorheological dampers: Part 1—Modeling

This work presents landing efficiency control of a six-degree-of-freedom aircraft model, which has a controllable landing gear system with magnetorheological damper. Due to lengthy contents, this work is divided into two parts. In Part 1, both the kinematic and dynamic equations of the six-degree-of-freedom aircraft model are derived. After determining the principal design parameters of magnetorheological damper based on commercial Beechcraft Baron B55 (passive oleo-strut type) damper, the kinematic equations are derived using the aircraft body coordinate frame and homogeneous coordinates of the reference frame, while the dynamic equations are derived using Euler–Lagrange equation to represent the heave, roll, and pitch motions of the aircraft model. In Part 2, the landing performance based on landing efficiencies is analyzed through the landing motions using various controllers.

Calibration of Transducers and of a Coil Compression Spring Constant on the Testing Equipment Simulating the Process of a Pallet Positioning in a Rack Cell

In a parking house with KOMA TOWER computer-controlled automated parking system it happens that a control system is locked out of service after a pallet has failed to reach the required position during the shifting of pallets, loaded with cars, into rack cells.In this paper is described testing equipment designed by the Institute of Transport, Faculty of Mechanical Engineering, VŠB Technical University of Ostrava for the purpose of simulating the process of pallets shifting into the rack cells in order that the frequency of error messages from the control system during the automated process of cars positioning in rack cells in the parking house may be limited.The paper details two completed parts of the designed testing equipment which provide for the calibration of strain-gauge force transducers and for the detection of coil compressive spring compression in relation to acting pressure force.The description of the third, principal design part will be provided in the next paper, together with the experimentally measured acting forces which generate, in both horizontal and vertical directions, as a pallet brake pulley rolls along a brake haunch length.

PRINCIPAL DESIGN TECHNIQUES OF RECONCILIATION OF ARCHITECTURE AND NATURE IN CHINESE GARDENS OF SUZHOU

Park and garden design of China initially had relatively few strict limitations and rules and there was a great deal of room for creativity. However study of gardens of Suzhou makes it possible to distinguish some basic compositional design features. Those features are: zoning of the park space; designing of routs for visi-tors; creation of contrast and background both in large landscape zones and in small-scale objects; “land-scape borrowing”; use of depth and succession of landscape views. A major challenge for the architect is creation of complex, multi-layered space, where walking routes between the compositional dominants play a significant role. The use of these design features visually extends the garden space, gives the visitor choice between several routes and enriches content of the garden. Besides, several main design objects can be dis-tinguished, such as: large and small water bodies; artificial mountains and stone groups; garden structures, including pavilions, terraces, towers and galleries; decorations and vegetation. Individual design objects and in particular the architectural structures allow us to elaborate the garden space in more detail. Chinese park is inconceivable without the synthesis between the nature and architecture. The acquisition of basic compositional design features allow us not only to better understand the organization of private gardens in China, but also to use them in own design practice.
