We consider a setting where not only the member agents are adaptive but also the multi-agent system viewed as an entity in its own right is adaptive. Specifically, the social structure of a multi-agent system can be reflected in the social norms among its members. It is well recognized that the norms that arise in society are not always beneficial to its members. We focus on prosocial norms, which help achieve positive outcomes for society and often provide guidance to agents to act in a manner that takes into account the welfare of others.}, number={1-2}, journal={ACM TRANSACTIONS ON AUTONOMOUS AND ADAPTIVE SYSTEMS}, publisher={Association for Computing Machinery (ACM)}, author={Mashayekhi, Mehdi and Ajmeri, Nirav and List, George F. and Singh, Munindar P.}, year={2022}, month={Jun} }

In this paper, a bilayer signalized control method is presented. In the lower layer, a colored stochastic Petri net controls the signal indication displays and stage transitions. In the upper layer, a supervisory logic layer decides which stage should be serviced next. The proposed model increases modularity, reduces complexity, and, more importantly, is capable of being used to implement various signal control strategies. The method is used to implement four different control strategies: pretimed control, fully actuated control, semiactuated control, and random stage selection (as a benchmark) in the context of a signalized traffic network containing six intersections. Extensibility and future potential research to further enhance the proposed method are discussed and proposed at the end.}, number={3}, journal={IEEE TRANSACTIONS ON INTELLIGENT TRANSPORTATION SYSTEMS}, author={List, George F. and Mashayekhi, Mehdi}, year={2016}, month={Mar}, pages={701–713} }

Guides have been created by organizations in several countries, and dozens of papers have been published in scientific journals on the theory and application of transport simulation; these works are aimed at guiding practitioners in the use of simulation tools. However, transport simulation still lacks a unified and comprehensive guide for use in practice. The lack of such a document leads to conflicts between modelers, agencies, and decision makers and allows inappropriate use of the models. The outcome is often inaccurate results, inefficient use of resources, and conflict. This paper reviews and analyzes the existing transportation simulation guides. It identifies gaps and limitations and proposes an outline for a comprehensive simulation manual that is based on stakeholder input. Review of the existing guidance documents reveals that almost all these documents focus on traffic operations, and they provide either broad guidelines for building simulation models or advice on using a specific software product. Other issues, particularly those related to topics such as safety assessments, environmental impacts, public transportation, pedestrians, bicycles, simulation algorithms, agent-based simulation, and multimodal simulation, are addressed in only a cursory fashion. This paper proposes a possible structure for a transportation system simulation manual that would cover the limitations and gaps in the existing literature. The proposed document would consist of five volumes: concepts, model building, verification and validation, results analysis, and case studies and supplementary materials. }, number={2561}, journal={TRANSPORTATION RESEARCH RECORD}, author={List, George and Mashayekhi, Mehdi and Bertini, Robert L. and Nevers, Brandon}, year={2016}, pages={45–52} }

Hybrid yarn made of electroconductive materials allows the creation of a set of solenoids with a ferromagnetic core made of steel yarn and a solenoid of conductive effect yarns made of copper. The woven fabric made of these yarns placed into an alternating electromagnetic field (EMF) exhibits a phenomenon where an alternating electric voltage is generated between the ends of the copper solenoid, and alternating magnetisation of the ferromagnetic core takes place. Twelve fabrics were produced, nine of which differed in the density with which the hybrid yarns were introduced as wefts, i.e. once every 25×2 tex cotton yarn, every two cotton yarns, and every three cotton yarns, and the remaining three were reference fabrics, without hybrid yarn. It was found that if measured at a frequency of 30 MHz, the fabrics containing hybrid yarns had 60% higher SE than the reference ones.}, number={6}, journal={FIBRES & TEXTILES IN EASTERN EUROPE}, author={Marciniak, Katarzyna and Grabowska, Katarzyna and Stempien, Zbigniew and Ciesielska-Wrobel, Izabela and Rutkowska, Aleksandra and Taranek, Dorota}, year={2016}, pages={109–115} }

Estimation of the PCI is based on the results of a visual inspection in which the type, severity, and quantity of distresses are identified. The purpose of this study is to develop an alternative approach for forecasting the PCI using optimization techniques, including artificial neural networks (ANN) and genetic programming (GP). The proposed soft computing method can reliably estimate the PCI and can be used in a pavement management system (PMS) using simple and accessible spreadsheet softwares. A database composed of the PCI results of more than 1,250 km of highways in Iran was used to develop the models. The results showed that the ANN- and GP-based projected values are in good agreement with the field-measured data. In addition, the ANN-based model was more precise than the GP-based model. For more straightforward applications, a computer program was developed based on the results obtained.}, number={12}, journal={JOURNAL OF TRANSPORTATION ENGINEERING-ASCE}, author={Shahnazari, Habib and Tutunchian, Mohammad A. and Mashayekhi, Mehdi and Amini, Amir A.}, year={2012}, month={Dec}, pages={1495–1506} }
