This study proposes a behavior-specific filtering method to improve behavior classification accuracy in Precision Livestock Farming (PLF). While traditional filtering methods, such as wavelet denoising, achieved an accuracy of 91.58%, they apply uniform processing to all behaviors. In contrast, the proposed behavior-specific filtering method combines Wavelet Denoising with a Low Pass Filter, tailored to active and inactive pig behaviors, and achieved a peak accuracy of 94.73%. These results highlight the effectiveness of behavior-specific filtering in enhancing animal behavior monitoring, supporting better health management and farm efficiency

The proliferation of 5G technologies and the vast deployment of Internet of Things (IoT) devices have heightened the demand for optimal spectrum utilization, necessitating robust spectrum management strategies. In this context, an efficient energy detector employing wideband spectrum sensing within a 5G environment is essential for identifying underutilized frequency bands suitable for cognitive radio applications across multiple sub-bands. While cooperative spectrum sensing (CSS) can enhance the detection capabilities of energy detectors amidst noise uncertainty, its performance often deteriorates under low signal-to-noise ratio (SNR) conditions. This study proposes an improved CSS framework that combines Maximal Ratio Combining (MRC) with the K-out-of-N fusion rule to address noise uncertainty in a complex Gaussian environment across multiple sub-bands in cooperative wideband spectrum sensing. Comparative performance analysis confirms that this integrated approach enhances detection probability and maintains a low false alarm rate across various low SNR scenarios, significantly outperforming traditional cooperative and non-cooperative wideband spectrum sensing methods. These results highlight the potential for advancing cognitive radio technologies by optimizing detection algorithms to improve performance under challenging conditions.

Developments in the field of generative-AI have made it extremely difficult to distinguish artificially generated content from real content. As a result, their reliable detection has become more important. The topic of this research is detecting speeches that are generated by future generative-AI models in unknown languages. It focuses on answering ”With what information does a model distinguish fake audio from real audio, does it learn how spoken languages sound, or does it learn a specific trait of generated speech waves?” Multiple models are trained on various datasets to detect synthetic audio signals generated by generative-AI models. After multiple sessions of trains and tests, the best test accuracy scores for different test sessions are 94.92% for known language from unknown generative-AI model, 98. 44% for an unknown language from known generative-AI model, and 95. 18% for an unknown language from unknown generative-AI model.

A physical unclonable function (PUF)-based method is presented for continuously authenticating the physical hardware provenance of data that a sensor streams over time to a receiving device. In contrast to existing PUF-based authenticated remote sensing techniques, the method does not make use of any PUF challenge-response pair (CRP) databases or PUF models. The new method, that we call a Sensor Ratchet, is based on the hitherto developed PUF-based CRP Ratchet protocol for continuously mutually authenticating a pair of devices over time. As such, the Sensor Ratchet inherits the lightweight computational requirements and secure properties of the CRP Ratchet. Three variations of the Sensor Ratchet are developed: a simplex form of authenticated data transfer in which a receiver is the initiator, a simplex form in which the sensor is the initiator, and a half-duplex form that additionally transmits physically authenticated information - such as control signals - to a sensor.

The study focuses on the innovations by artificial intelligence in the workplace that are affecting the productivity of the staff and the overall performance of businesses. It attempts to uncover the mechanism behind technologys technological impact on business operations and labor productivity. A quantitative research technique was used in this study with SmartPLS. It is found in a study that out of 350 small and medium-sized company samples, the first two had the highest adoption rates. The study specifies that perceived value, as well as the ease of use, has a major effect on the adoption of AI solutions. Technology development is one such method, through which increasing the level of work of people in the business raises the companys productivity. The positive experience increases business performance, therefore accuracy of business management to understand the employees of the business and customer satisfaction are positively related these points have been illustrated in this paper. Besides fact that study is mainly based on self-reporting data it may be biased at that point. As next study could thoroughly investigate long-term impacts of technology adoption on productivity in various disciplines of economy. A company can foster productivity of its workforce and boost performance by making available to them friendly AI tools as well as by providing them with training. This investigation contributes to understanding how AI technology can increase organizational performance in a significant way according to theoretical frameworks such as TAM model and Resource-Based View (RBV).
