Abstract

Purpose

Automation of detecting cracked surfaces on buildings or in any industrially manufactured products is emerging nowadays. Detection of the cracked surface is a challenging task for inspectors. Image-based automatic inspection of cracks can be very effective when compared to human eye inspection. With the advancement in deep learning techniques, by utilizing these methods the authors can create automation of work in a particular sector of various industries.

Design/methodology/approach

In this study, an upgraded convolutional neural network-based crack detection method has been proposed. The dataset consists of 3,886 images which include cracked and non-cracked images. Further, these data have been split into training and validation data. To inspect the cracks more accurately, data augmentation was performed on the dataset, and regularization techniques have been utilized to reduce the overfitting problems. In this work, VGG19, Xception and Inception V3, along with Resnet50 V2 CNN architectures to train the data.

Findings

A comparison between the trained models has been performed and from the obtained results, Xception performs better than other algorithms with 99.54% test accuracy. The results show detecting cracked regions and firm non-cracked regions is very efficient by the Xception algorithm.

Originality/value

The proposed method can be way better back to an automatic inspection of cracks in buildings with different design patterns such as decorated historical monuments.

Abstract

Purpose

A hypothesis developed in this paper models the relationship between the borrower and the bank as a dynamic game based on incomplete information (business game) and seeks an equilibrium point at which the facilitated applicant can act according to the terms of the loan agreement once the contract is signed and meet the requirements of the contract.

Design/methodology/approach

The primary assumption in the formation of the Islamic bank in Islamic society is that the members of the society are Muslims and act according to religious orders. However, the non-fulfillment of divine principles and orders is always possible. In partnership agreements, the risk of infringement is reduced and corrupt contracts are prevented in some circumstances. Our basic model was constructed using the Beer-Quiche classic game, which has been modified dynamically along with a generalization of complexity terms. The information asymmetry led us to use a heterogeneous belief system to evaluate the probability of the customer transmitting a low credit risk signal to the bank and the probability of the customer transmitting a high credit risk signal to the bank. There are several assumptions of the basic model that are released in the extended model by the presence of a social inspector, by exploring credit risk signals in the generalized model and by considering various commitment levels in the comprehensive model.

Findings

As a result, it is observed that there is no Nash equilibrium in cases where the customer applies separation strategies. But if the pulling strategies are applied, the Nash equilibrium can be achieved under certain conditions, including inspection bodies in the banking system, the creation of necessary transparency and the proper treatment of criminals by government and regulatory bodies. So, by using alternative belief systems, applying different filters and paying attention to all sectors of the economy, new Nash equilibrium points can be achieved. Moreover, multi-stage facilities payment reduces the risk of corrupt contracts.

Originality/value

This paper sets out to analyze Nash Equilibrium and its possible encounter in Islamic Banking for the first time, utilizing a Bayesian Game-Theoretic framework. A major aspect of the research is the contribution to a better understanding of the role of transparency and government oversight in the implementation of Islamic banking regulatory standards.

Abstract

Purpose

This study aims to investigate how the Chinese Belt and Road Initiative (BRI) and Chinese outward foreign direct investments (FDI) impact the Belt and Road countries (BRCs). It draws on postcolonial theory to investigate the (geo)political objectives behind the financial and economic means.

Design/methodology/approach

In line with the nature of postcolonial studies, the study applies a discourse analysis integrating it with empirical data on indebtedness and trade.

Findings

This study finds that FDI and the BRI, as a development project, need to be considered a double-edged sword for the receiving countries. The authors provide evidence that China has instrumentalized financial and economic means to gain political influence and pursue geopolitical ambitions. Moreover, investments into sensitive sectors (e.g. energy, infrastructure), combined with the BRCs’ inability to pay back loans, could eventually lead to China gaining control of these assets.

Research limitations/implications

The study investigates the financial and economic means that are instrumentalized to gain political influence while not considering flows of technology and know-how. It also limits itself to the study of FDI coming from one specific country, i.e. China. Therefore, no comparison and evaluation are made of FDI from other countries, such as the USA or European countries.

Practical implications

By revealing noncommercial objectives and geopolitical ambitions that China pursues through the BRI, the authors derive policy implications for the BRCs, third countries and China.

Originality/value

The study contributes to postcolonial theory and neocolonialism by investigating how China uses financial and economic means to achieve noncommercial objectives and pursue geopolitical ambitions. Additionally, the authors enhance the understanding of FDI by highlighting more subtle aspects of the complex and contextual nature of FDI as a social phenomenon, which have been overlooked thus far. The authors challenge the predominant positive framing of FDI and provide a counterpoint to the way FDI is often coined.

Abstract

Purpose

Design for adaptability and disassembly (DfAD) is an effective method to reduce construction and demolition waste generation, landfill loads and greenhouse gas generation; preserve natural resources; and increase environmental awareness in the construction industry. However, it is an underexplored strategy due to a lack of information about projects and a set of agreed guidelines to guide buildings deconstruction. This study aims to understand how DfAD can support the sector’s transition toward circularity.

Design/methodology/approach

Through an integrative literature review, this study analyzed the current publications and terminologies used, identified the main themes discussed and described the key criteria for integrating deconstruction in the building design stage.

Findings

The results showed that the term DfAD encompasses different ecodesign strategies and is concentrated in six major thematic categories (design and construction principles, tools for DfAD, components and connections for DfAD, barriers, drivers and guidelines for DfAD, existing building stock potential and selective deconstruction process). In total, 60 criteria were presented to guide the deconstruction of buildings, emphasizing standardization, modularization and prefabrication of materials and components as fundamental requirements.

Originality/value

The study highlighted the need to expand the knowledge and training of the design team, establish public policies and tax incentives and develop tools, methods, and circular indicators to enable the implementation of deconstruction strategies for buildings.
