AbstractHuman-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.

This paper investigates the deploying time (or response time) of an active hood lift system (AHLS) of a passenger vehicle activated by gunpowder actuator. In this work, this is accomplished by changing principal design parameters of the latch part mechanism of the hood system. After briefly introducing the working principle of the AHLS operated by the gunpowder actuator, the governing equations of the AHLS are formulated for each different deploying motion. Subsequently, using the governing equations, the response time for deploying the hold lift system is determined by changing several geometric distances such as the distance from the rotational center of the pop-up guide to the point of the latch in the axial and vertical directions. Then, a comparison is made of the total response time to completely deploy the hood lift system with the existing conventional AHLS and proposed AHLS. In addition, the workable driving speed of the proposed AHLS is compared with the conventional one by changing the powder volume of the actuator.

Kajian ini bertujuan untuk menentukan keupayaan menyelesaikan masalah matematik bukan rutin di kalangan pelajar tingkatan dua di beberapa buah sekolah sekitar daerah Johor Bahru. Ia difokuskan kepada keupayaan pelajar dalam proses menyelesaikan masalah yang merangkumi: proses memahami masalah, merancang strategi penyelesaian, melaksanakan strategi dan akhir sekali menyemak serta menilai jawapan. Kajian ini merupakan kajian tinjauan. Persampelan adalah secara persampelan kelompok. Sampel kajian adalah terdiri daripada 70 orang pelajar tingkatan dua. Tiga alat kajian digunakan, iaitu ujian penyelesaian masalah matematik bukan rutin, soal selidik berkaitan sikap terhadap penyelesaian masalah dan temu bual berstruktur. Tiga kategori yang dinilai dalam inventori sikap adalah kesanggupan dalam aktiviti menyelesaikan masalah, ketabahan ketika menyelesaikan masalah dan keyakinan diri dalam menyelesaikan masalah. Dapatan menunjukkan bahawa pelajar tingkatan dua mempunyai kemahiran memahami masalah pada tahap tinggi tetapi mempunyai kemahiran merancang strategi dan menulis jawapan pada tahap yang sangat lemah. Manakala bagi kemahiran melaksana strategi, pelajar tingkatan dua ini berada pada tahap yang sederhana dalam menyelesaikan masalah matematik bukan rutin. Dari segi sikap terhadap penyelesaian masalah, pelajar tingkatan dua mempunyai tahap sikap yang tinggi dalam kesanggupan dan ketabahan tetapi mempunyai tahap sikap yang sederhana dalam keyakinan. Temu bual pula mendapati terdapat perbezaan pandangan dan pola penyelesaian antara pelajar yang mendapat skor terendah dan pelajar yang mendapat skor tertinggi ketika menjawab soalan matematik bukan rutin. Kata kunci: Masalah matematik bukan rutin; proses menyelesaikan masalah; kesanggupan; ketabahan; keyakinan diri This study was designed to identify student’s ability in solving non–routine mathematical problem among form two students from schools in the district of Johor Bahru. Its focus is on student’s ability on problem solving process that is: to understand the problem, to plan the problem solving strategies, to carry out the strategies, and lastly to review the answers as well as the overall solution. This study was a form of survey with a cluster sampling. A total of 70 form two students were chosen as research sample. Three instruments were used: non–routine problem solving test, a questionnaires about problem solving attitudes and a structured interview. Three categories on attitudes inventory evaluated were willingness, perseverance and self–confidence on problem solving activity. The findings of the study showed that form two students were skilled in the understanding of the problem but have low skills in planning problem solving strategies and in reviewing the answers. These students have moderate skills to carry out the strategies in solving non-routine mathematical problem. Results of attitude on problem solving showed that form two students have high scores for attitudes on willingness and perseverance but average scores for attitude on confidence. The interview also showed student opinion varied and there is a marked difference in patterns of solving problems across students with lowest scores and highest scores. Key words: Non–routine mathematical problem; problem solving process; willingness; perseverance; self–confidence

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.

Herein, we apply theoretical models to characterize the transfer function and frequency response of a complex optoelectronic circuit that comprises a primary ultrafast sampling circuit followed by a cascade connection of N demultiplexing stages. The successive radio-frequency optoelectronic samplers were based on the cascade connection of positive-intrinsic-negative-photodiodes (PIN-PDs). We developed a procedure to calculate the principal design parameters that allows us to use optical power for each sampling and demultiplexing stage, such that the circuit can be designed based on the application requirements. The results obtained from the theoretical models were compared with the measurements obtained from the 2.5 GS/s sampling circuit connected in cascade with a 1.25 GS/s and a 625 MS/s demultiplexing circuit implemented using commercial PIN-PDs

This paper aims to develop of a robust analytical approach for computation of the principal design parameters for a special-purpose involute hob for machining of cluster gear. The specific combination of design parameters for a precision hob with particular value of the hob-setting angle is given. This combination of parameters includes (a) the hob outside diameter, (b) the base diameter of the hob, and (c) the required value of the hob-setting angle. The specific combination of these design parameters for the involute hob determined here allows machining of cluster gear with the shortest possible neck width. Numerous computer codes for computation of the design parameters of an involute hob are developed using the commercial software MathCAD-Scientific. Application of the special-purpose hob would allow reduction of size and weight of both the cluster gear itself and the whole gear transmission including housing. The reported results of the research are ready for application in industry.

The usefulness of radar plotting, as at present practised, may be considerably enhanced by the application of a doppler radar technique which gives instantaneous measurement of relative velocity components and quickens the whole plotting process. The range and bearing of the target are given by an ordinary radar PPI, from which the rate of change of bearing may also be determined. The doppler radar gives an immediate measurement of the radial component of relative velocity and the derivative of radial velocity: from these data the course and speed of the target may readily be determined, using an automatic computer if so desired. Possible errors in deducing the true aspect and speed are discussed and the mode of operation, and principal design parameters of suitable doppler radar are given.

A dynamic analysis is presented relating the principal design parameters of a constant force type, dissipative shock absorber to the forces experienced by a resilient lading. The analysis, which correlates the effects of coupler force, lading force, cushion travel, closure time, impact speed, and friction, represents an application of classical mechanics to a dynamical system with sliding friction (Coulomb damping). Although a lumped-parameter analysis forms the basis of the derivation, a procedure is described which takes into account the mass- and compliance distribution within the lading.
