The Federal Highway Administration (FHWA) mandates biannual bridge inspections to assess the condition of all bridges in the United States. These inspections are recorded in the National Bridge Inventory (NBI) and the respective state’s databases to manage, study, and analyze the data. As FHWA specifications become more complex, inspections require more training and field time. Recently, element-level inspections were added, assigning a condition state to each minor element in the bridge. To address this new requirement, a machine-aided bridge inspection method was developed using artificial intelligence (AI) to assist inspectors. The proposed method focuses on the condition state assessment of cracking in reinforced concrete bridge deck elements. The deep learning-based workflow integrated with image classification and semantic segmentation methods is utilized to extract information from images and evaluate the condition state of cracks according to FHWA specifications. The new workflow uses a deep neural network to extract information required by the bridge inspection manual, enabling the determination of the condition state of cracks in the deck. The results of experimentation demonstrate the effectiveness of this workflow for this application. The method also balances the costs and risks associated with increasing levels of AI involvement, enabling inspectors to better manage their resources. This AI-based method can be implemented by asset owners, such as Departments of Transportation, to better serve communities.

Archaeological research on palaces and architectural spaces related to power factions allow a better understanding of the social dynamics of political economies. Several types of palaces appear in Mesoamerica according to distinct forms of sociopolitical organization. For Tlaxcallan, a Late Postclassic (A.D. 1250/1300–1519) geopolitical state-level polity with a highly collective government, the existence of palaces has been questioned. We reconsider the existence of palaces in Tlaxcallan through the contextual analysis of an architectural complex (CA-2) of Tepeticpac, one of the sectors of the conurbated area. We evaluate the functionality of CA-2 as a palace by examining the processes of occupation and abandonment of the building in relation to its architectural and stratigraphic sequence and the type of associated artifacts. The comparison between archaeological and historical data indicate that Tlaxcallans probably had palaces, but they were less ostentatious compared to others found in societies with more centralized governments.
