2025-03-13T12:26:30+02:00

The multipurpose material, cellular lightweight concrete (CLWC), comprises cement, fly ash, and a foaming agent. The popularity of cellular lightweight concrete can be attributed to its low weight, which lowers the structure's self-weight. With its cementitious qualities and mechanically entrained foam in the cement-based slurry, cellular lightweight concrete (CLWC) is a novel material that has significantly increased in popularity in the construction industry over the past ten years. CLC blocks have poor strength issues while being lightweight concrete with strong water absorption and thermal insulation qualities. CLC blocks are altered with additives like fly ash, silica fume, and marble dust to combat this issue. Due to its low strength, a study reveals that silica fume and marble dust have been utilized in several experiments to increase stability. The samples will undergo compressive strength, thermal conductivity, and water absorption tests. Regarding compressive strength, 3% silica fume and 7% marble dust work well. These findings are based on seven and 28-day curing times, while 14-day curing may be investigated in the future.

2025-03-18T10:38:54+02:00

Laser induced breakdown spectroscopy (LIBS) is a versatile technique that is used to determine elemental composition in different samples. It is simple and fast multi-elemental analysis technique which provides potential tool in situ chemical analysis with high resolution, better limit of detection (LOD) and is cost efficient. Smoking tobacco in cigarettes amplifies the risk of growing certain diseases such as cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. About 80% of lung cancer as well as about 80% of all lung cancer deaths are due to smoking. Smoking tobacco is a considerable source of consuming several harmful and toxic elements that are unhealthy for human body. The presence of some toxic elements causes serious health concern to active as well as to passive smokers. In the present study, we employ LIBS technique to identify and detect toxic and harmful elements in tobacco and ash from four popular Pakistani cigarette brands, ensuring human health protection, agricultural safety, and environmental sustainability. The Q-switched ND: YAG (neodymium-doped yttrium aluminum garnet) laser (λ=1064 nm) with laser energy 90 mJ and pulse duration 10 ns were used to ablate the samples. From the recorded optical emission spectra of these samples several elements were detected (Fe, Ca, Mn, Sc, Ti, Cr, Sc, Sr and Ni) among which Chromium Cr, Nickel Ni and Strontium Sr are highly toxic elements. Furthermore, the presence of toxic and heavy metals in ash could be significant contributor to metal load in soil as well as for human body. We calculated the electron temperature (Te) by the Boltzmann Plot Method from the spectroscopic analysis of the transition lines of Fe-I (iron). Stark Broadening Method was used to determine electron number density (Ne) from the transition line of Fe-I at 422.413 nm and 649.25 nm for tobacco and ash sample respectively, under the assumption of local thermodynamic equilibrium. The present results demonstrate that LIBS is a powerful diagnostic tool for effectively tracing harmful and toxic elements in various solid samples, facilitating the development of protective environmental measures.

2025-03-19T08:09:40+02:00

Cloud Radio Access Networks (C-RAN) is one of the novel approaches to cell network architecture by centralizing baseband processing devices (BBUs) into cloud statistics facilities and dispensing far off radio heads (RRHs) at mobile web sites. While C-RAN supports aspects of higher scalability, flexibility and network management, it also creates significant large power-intake demanding scenarios due to its operation with multiple RRHs and the power-in-depth BBU pools. This paper examines the major challenges in realizing power efficiency in C-RAN with dynamic site traffic loads, idle power consumption as well as cooling requirements in central data centers. For example, we consider several alternative designs such as dynamic BBU pooling, sleep mode techniques for RRHs, AI-based visitors prediction, and integration of renewable sources of energy. Hence, based on such results, it can be inferred that strength consumption decreases significantly without degrading the community performance with such technologies, especially by implementing them at various layers of the network. This work concludes with some future research guideline on how to improve the energy efficiency of C-RAN in the scenario of 5G and previous networks.

AI-POWERED ANOMALY DETECTION IN SOFTWARE LOGS: A MACHINE LEARNING APPROACH FOR PROACTIVE FAULT DIAGNOSIS AND SELF-HEALING SYSTEMS

2025-03-20T09:27:47+02:00

Due to the complexity of modern software systems the amount of logs generated to assist with monitoring and fault diagnosing has become way too large for manual processing. This paper aims at developing the architecture for identifying anomalous patterns in the software log files through the application of advanced machine learning and deep learning algorithms towards fault diagnosis for self- healing systems. Traditional rule based approaches cannot fit the modern complex scenarios as well as the large amounts of data that are produced in the form of logs. Machine learning approaches, including deep learning structures like LSTMs and Transforms, are more effective at detecting anomalies due to their ability to capture contextual dependencies inherent in log sequences. It also offers resolutions to the problem of a scarcity of labeled data in the utilization of self-supervised learning approaches, along with contrastive learning. Additionally, self-C damaged control mechanisms based on reinforcement learning as well as a rule and based automation recurrently correct faults decreasing the non-availability of the system. Several models are assessed on log datasets with different evaluation metrics such as precision, recall, F1-score, and AUC-ROC. The results when testing suggest that Transformer-based models yield the best performance as compared to other conventional machine learning methods while at the same time requiring more computational resources. Self-healing systems cut down on downtime by as much as 68.2 percent; such characteristics make AI promising for strengthening system performance. That is why some issues, like model interpretability, high computation costs, and real-time processing, are still present. Mitigating these challenges by employing lightweight deep learning models, explainable AI methods, and the ability to deploy these algorithms at scale will be instrumental in advancing the use of AI-based anomaly detection and self-healing systems in safety- critical software applications. This work presents a state-of-the-art review of AI- based log anomaly detection methods and discusses potential research directions for improving scalability, interpretability, and practicality in real-world applications.

Documents scanning has become a necessary phase in official record keeping of everyday business environment. Typically, scanned document images in digitized format suffer from various types of noise which create serious problems at document reading time. This noise may be due to several reasons low quality paper, paper aging, scanner assembly and tonner, unskilled machine operator, or due to some copying machine artifacts. The removal or elimination of noise in scanned documents is still a big challenge for researchers in the digital era. Already performed work on digitized handwritten, and machine-printed degraded historical documents, but we have experimented with different datasets such as the Media Team Document Database manually scanned noisy documents, and decided to use, a collection of scanned noise-affected documents, which are available on the websites. We have transformed the noise-influenced image document into a binarized document. After this, we applied noise reduction techniques for textual data enhancement so that the text would be in readable and noise-free form. An Adaptive Gaussian Mixture Model based on Expectation Maximization (EM) has been used to restore the image pixels, with the values expected to be the original ones. The enhanced text in its visual aspect and improved quantitatively measured parameters show the restored documents. We have calculated Signal to Noise Ratio (SNR), Mean Square Error / Mean Square Difference (MSE/MSD), Peak Signal Noise Ratio (PSNR), Contrast, and Energy for quantitative parameters to evaluate the performance measures of the proposed method of document restoration comparative to the state-of-the-art methods. Our research is quantitative, as we have performed experiments on digital sensor data and the evaluation of the results based on computational techniques. Our results are successful, support the proposed methodology, and perform well in comparison to the state-of-the-art methods. Overall, the proposed methodology is easy to understand and simple to implement.

USING GENERATIVE AI FOR SIMULATING CYBER SECURITY ATTACKS AND DEFENSE MECHANISMS: A NEW APPROACH TO AI-DRIVEN CYBER THREAT MODELING

2025-03-22T10:10:41+02:00

Awareness of cyber risk is a crucial factor in today’s world, where new forms of threats are potentially dangerous to companies’ IT frameworks. The reaction-based detection, particularly the signature based detection and the rule based systems have their limitations in combating new and advanced attacks because they are deficient in the proactive approach. With threats emerging in the cyber realm in a dynamic way, it is imperative that organizations seek out active and conscious defenses. This paper aims at bringing forward the possibility of using Generative Artificial Intelligence (AI) in the process of modeling cyberattacks and defense strategies: a new approach to Defending AI Cyber Threats. Generative AI models such as GAN and VAE are used to generate realistic attack scenarios that are useful in assessing and improving security systems. These allow the emulation of new scenarios that have not yet been experienced in cyberspace that, in turn, can be used to assess defence mechanisms. This is why this approach is popular in cybersecurity research since it can represent such threats as APTs and other types of threats that may appear over time while advancing through the specific attack life cycle. Through leveraging generative AI for threat modeling, organizations start shifting from a reactive approach to threat modeling, with security features matching up with the advancing complexity of threats.
