Among these, the legal issue concerns whether chatbots are responsible for what they respondand whether what they provide is their intellectual property. Essentially, can personalities be attributed to chatbots? The present article finally concludes, with the analytical-descriptive approach, that chatbots may potentially possess a degree of personality in the future, but in current circumstances, the effects and content provided by chatbots are attributed to their owners and creators.

It analyses the problem from the viewpoint of the governor's dilemma and the control/competence conflict, the linked problem of the rent-seeking of agents/intermediators and consumers of financial instruments. Political accountability problems are enhanced by the materiality of the technologies used, i.e. algo trading. Design/methodology/approach – The paper theoretically conceptualizes and empirically illustrates the argument. Findings – The paper finds that regulators of digitalized financial markets are faced with considerable problems and depend on private agents when regulating financial transactions. However, the new technological instruments also offer new possibilities for securing compliance. Research limitations/implications – Further research should focus more in-depth on the cooperation between public and private actors in the specification and implementation of regulatory details. It should further investigate the conditions which allow regulators to use RegTech in the surveillance of financial firms. Practical implications – Since financial market transactions are opaque for most users, the creation of more transparency is crucial to hold regulators accountable in their activity of surveillance of financial firms. New algorithm-based technologies may lend important support in doing so. Originality/value – By linking the different analytical perspectives, i.e. the governor's dilemma vis-à-vis the intermediator or agent and the possible rent-seeking of intermediators, under the condition of a highly developed technology of financial transactions as well as the market structure, the paper offers new insights into the limits as well as new opportunities of regulating financial markets allowing for political accountability of regulators and financial firms.","source":"DOAJ","year":2023,"language":"","subjects":["Regulation of industry, trade, and commerce.

Our system is composed of two main processes, day time and night time processes. In the night time, the vehicles are detected based on their taillights and headlights. First of all, the 2D-DWT (Two Dimensional Discrete Wavelet Transform) and the background subtraction are applied to the input image. Then, the connected component technique is used to extract the region of interest. If it is the daytime, the connected component candidates are taken as potential vehicles after applying a pre-processing algorithm to improve the result. If it is the night-time, a filtering operation is used to keep only the bright white and red connected component candidates (which represent potential headlights and taillights, respectively). Finally, potential lamp sets are formed by grouping the extracted components on the basis of their positions, sizes, and colours. The potential extracted vehicles are classified as a vehicle or non-vehicle by using a pre-trained CNN (Convolutional Neural Network) classifier. The proposed system was tested and evaluated using different works from the literature. The experiments show that our proposed system has reached a high accuracy in terms of vehicle detection process whether in day or night time. The experiments were performed using four different videos and were implemented using the C++ language, which facilitates mathematical computation, and its OpenCV library, which is used to run the image processing algorithms used, as well as the TensorFlow library, which facilitates transfer learning of pre-trained CNN models.","source":"DOAJ","year":2023,"language":"","subjects":["Transportation and communication"],"doi":"10.2478/ttj-2023-0020","url":"https://doi.org/10.2478/ttj-2023-0020","is_open_access":true,"published_at":"","score":67},{"id":"doaj_10.3390/logistics6020028","title":"Impact of Additive Manufacturing on the Supply Chain of Aerospace Spare Parts Industry—A Review","authors":[{"name":"Binoy Debnath"},{"name":"Md Shihab Shakur"},{"name":"Fahmida Tanjum"},{"name":"M.

Such a DSCT promises to enable several improvements all across the supply chain while also be capable of simulating and evaluate several different scenarios for the supply chain. Therefore, the DSCT will not only be able to optimize multi- and intermodal supply chains but also makes them potentially more robust by identifying possible issues early on. This paper discusses the major requirements that such a DSCT must fulfil to be useful and how several information technologies that matured in recent years or are about the mature are the key enablers to fulfil these requirements.
