A valuable technique during concept development is rapid prototyping of software for key design components. This approach is particularly useful when the optimum design approach is not readily apparent or several known alternatives need to be rapidly evaluated. A problem inherent in rapid prototyping is the lack of a "target system" with which to interface. Some alternatives are to develop test driver libraries, integrate the prototype with an existing working simulator, or build one for the specific problem. This paper presents a unique approach to concept development using rapid prototyping for concept development and scenario-based simulation for concept verification. The rapid prototyping environment, derived from artificial intelligence technology, is based on a blackboard architecture. The rapid prototype simulation capability is provided through an object-oriented modeling environment. It is shown how both simulation and blackboard technologies are used collectively to rapidly gain insight into a tenacious problem. A specific example will be discussed where this approach was used to evolve the logic of a mission controller for an autonomous underwater vehicle.

Cryptography is the science and art of maintaining the security of messages when messages are sent from one place to another. One of the ways securing the form of text message information is by the encryption process using the Vigenere Cipher algorithm and utilizing the One Time Pad (OTP) algorithm as a key generator, where the message will be random when it is opened. The message encryption process used the vigenere cipher algorithm while OTP is used to secure the key with the same formula. After this research has been done, an application was designed to secure text messages by converting the text message into a random message so that the message was unreadable due to a secret message that could not be known by others. The results achieved can secure an encrypted message that cannot be reopened and if those messages were reopened, they must be decrypted.

MnBi2Te4 (MBT) is the first intrinsic magnetic topological insulator with the interaction of spin-momentum locked surface electrons and intrinsic magnetism, and it exhibits novel magnetic and topological phenomena. Recent studies suggested that the interaction of electrons and magnetism can be affected by the Mn-doped Bi2Te3 phase at the surface due to inevitable structural defects. Here we report an observation of nonreciprocal transport, i.e. current-direction-dependent resistance, in a bilayer composed of antiferromagnetic MBT and nonmagnetic Pt. The emergence of the nonreciprocal response below the Néel temperature confirms a correlation between nonreciprocity and intrinsic magnetism in the surface state of MBT. The angular dependence of the nonreciprocal transport indicates that nonreciprocal response originates from the asymmetry scattering of electrons at the surface of MBT mediated by magnon. Our work provides an insight into nonreciprocity arising from the correlation between magnetism and Dirac surface electrons in intrinsic magnetic topological insulators. © 2022, CC BY.

AIP Conference Proceedings 2023年第1期2941卷

作者： Yanuar Prabowo Naila Najati Yanuar Firmansyah Kandi Rahardiyanti Iwan Nofi Yono Putro Teguh Praludi Cahya Edi Santosa Hendi Santosa Gunawan Setyo Prabowo Research Center for Aeronautics Technology National Research and Innovation Agency Bogor Indonesia Research Center for Satellite Technology National Research and Innovation Agency Bogor Indonesia Research Center for Rocket Technology National Research and Innovation Agency Bogor Indonesia Center for Data and Information National Research and Innovation Agency Kebumen Indonesia Research Center for Telecommunication National Research and Innovation Agency Bandung Indonesia Electrical Engineering Study Program Faculty of Engineering University of Bengkulu Bengkulu Indonesia

The datalink system is required for communication between the UAV (Unmanned Aerial Vehicle) to the GCS (Ground Control System). In this research, a hairpin BPF (Band Pass Filter) filter will be designed to develop block RF components in the UAV (Unmanned Aerial Vehicle) datalink system. The filter is designed at specific ISM (Industrial, Scientific, Medical) for frequency of 2.401-2.483GHz according to WiFi application with standard 802.11 b/g/n. The UAV (Unmanned Aerial Vehicle) datalink system with this frequency can pass telemetry data and payload data in one frequency channel. NPC H220A substrate with a dielectric constant of 2.18 and a thickness of 1.2 mm was used to design the BPF filter. The filter simulation results show the S11 values ranging from <-18.38 dB to-20dB at a frequency of 2.401GHz – 2.483GHz. Insertion loss values are obtained from <-1.4 dB to 0.76 dB. It is hoped that this filter design can be used for RF system applications on the UAV (Unmanned Aerial Vehicle) communication datalink that is being developed.

A comprehensive approach utilizing quantum machine learning in the study of corrosion inhibition on quinoxaline compounds

Artificial Intelligence Chemistry

引用

Artificial Intelligence Chemistry 2024年第2期2卷

作者： Muhamad Akrom Supriadi Rustad Hermawan Kresno Dipojono Ryo Maezono Study Program in Informatics Engineering Faculty of Computer Science Universitas Dian Nuswantoro Semarang 50131 Indonesia Research Center for Materials Informatics Faculty of Computer Science Universitas Dian Nuswantoro Semarang 50131 Indonesia Quantum and Nano Technologies Research Group Faculty of Industrial Technology Institut Teknologi Bandung Bandung 40132 Indonesia School of Information Science Japan Advanced Institute of Science and Technology Ishikawa 923-1292 Japan

In this investigation, a quantitative structure-property relationship (QSPR) model coupled with a quantum neural network (QNN) was used to explore the corrosion inhibition efficiency (CIE) of quinoxaline compounds. Integrating quantum chemical properties (QCP) features reduced computational burden by strategically reducing the features from 11 to 4 while maintaining prediction accuracy. QNN models outperform traditional methods like artificial neural networks (ANN) and multilayer perceptron neural networks (MLPNN), with a coefficient of determination (R 2 ) value of 0.987, coupled with diminished root mean square error (RMSE), mean absolute error (MAE), and mean absolute deviation (MAD) values of 0.97, 0.92, and 1.10, respectively. Predictions for six newly synthesized quinoxaline derivatives: quinoxaline-6-carboxylic acid (Q1) , methyl quinoxaline-6-carboxylate (Q2) , (2 E ,3 E )-2,3-dihydrazono-1,2,3,4-tetrahydroquinoxaline (Q3) , (2 E ,3 E ) 2,3-dihydrazono-6-methyl-1,2,3,4-tetrahydroquinoxaline (Q4) , ( E )-3-(4-methoxyethyl)-7-methylquinoxalin-2(1 H)-one (Q5) , and 2-(4-methoxyphenyl)-7-methylthieno[3,2- b ] quinoxaline (Q6) , show remarkable CIE values of 95.12, 96.72, 91.02, 92.43, 89.58, and 93.63 %, respectively. This breakthrough technique simplifies testing and production procedures for new anti-corrosion materials.

The associative property of addition facilitates the change of the group member. If the group members are molecules, can we apply this property to study a chemical reaction? The aim of this paper is to use the associative property of addition to design reaction pathways of methyl acetate hydrolysis in the acid environment. The reaction is found in Alzheimer’s Disease. We evaluate the designed pathways using activation energy obtained from density functional theory calculation. The results show the associative property of addition can be used to design four reaction pathways of the hydrolysis. The calculations show the acidity significantly affected the activation energy. This result agrees with the common knowledge. Hence, we have demonstrated the usefulness of the associative property of addition in designing chemical reaction pathways.

Quantum tunneling phenomenon allows a high-barrier reaction to occur even though thermal energy is not sufficient to surmount the barrier. The phenomenon has been suggested to exist in the isomerization of methylhydroxycarbene which occured at 11 K. Here we study the quantum tunneling that occured in the isomerization of methylhydroxycarbene to acetaldehyde and to vinyl alcohol based on density functional calculations. The isomerization pathways are determined under the effect of various solvents which are modeled by polarizable continuum model (PCM). We use Wentzel-Kramers-Brillouin (WKB) approximation to calculate the tunneling probability (T) and extend the usefulness of T into isomerization rate. The results show that the solvents give a significant effect on the isomerization rate of methylhydroxycarbene to acetaldehyde but an insignificant one on the isomerization rate to vinyl alcohol.
