Research in the International Journal of Vehicle Performance discusses a new integrated sensing and positioning system that can improve how autonomous locomotives navigate underground mining tunnels. This is one of the most challenging environments for vehicle automation, given the potential for hazards. The team has combined advanced laser-based mapping with wireless positioning and demonstrates that their system promises safer and more reliable navigation in settings where traditional sensing technologies often fail.

Underground mining poses distinct problems for autonomous vehicles. Tunnels are narrow, poorly lit, and often filled with dust and smoke, conditions that render conventional cameras almost useless and reduce the effectiveness of radar. This study addresses these challenges with a hybrid approach that pairs Light Detection and Ranging (LiDAR) sensors with Ultra Wide Band (UWB) wireless positioning.

LiDAR works by emitting laser pulses and measuring the time it takes for the light to return after bouncing off nearby objects. Unlike cameras, LiDAR does not depend on ambient light and can generate detailed 3D maps even in visually obscured environments. But the raw data it produces is often noisy and difficult to interpret, especially in cluttered or uneven spaces like those found in mining tunnels.

To refine this data, the researchers employed a technique known as multi-iteration plane fitting, which systematically isolates the ground surface from the rest of the environment. This step is essential for identifying true obstacles rather than confusing irregularities in the terrain for actual hazards. Once the ground is mapped, remaining data points, representing non-ground objects, are grouped into clusters.

Clustering in irregular environments presents its own difficulties. Traditional algorithms can misinterpret the scene, either by merging separate objects into one or splitting a single object into several false positives. The research team addressed this by analysing the scan line distribution from the LiDAR sensors, that is, the geometric pattern in which the laser sweeps across the environment. This allowed them to group points that belong to the same physical object more effectively. This approach not only improves obstacle recognition accuracy but also speeds up data processing by more than a fifth, which is important for systems operating in real time.

As artificial intelligence (AI) continues to transform how images and video are created, concerns about the manipulation of digital content have grown. Research in the International Journal of Forensic Engineering discusses how AI can be used to fight back and find the fakes.

Deepfakes, videos or images that have been manipulated using AI to depict events that never occurred and words that were never uttered, pose a growing threat to public discourse, politics, criminal investigations, and scientific integrity. These convincing forgeries are typically generated by a form of AI known as Generative Adversarial Networks (GANs). In a GAN, two neural networks compete: one creates realistic fake images, while the other attempts to identify the deception. As they evolve, so the system becomes adept at producing forgeries that are difficult even for experts to distinguish from authentic content.

Such technologies have not only led to blurred lines between real and artificial but also raised critical questions for journalism, law enforcement, and scientific publishing, where the authenticity of visual evidence can have serious consequences. As the manipulation of media becomes more sophisticated, traditional detection methods, such as spotting anomalies in shadows or unnatural features, have proven inadequate.

The work in IJFE has repurposed a relatively simple machine-learning model to detect deepfakes with high accuracy. The researchers tested three convolutional neural network (CNN) architectures, ResNet-50, AlexNet, and LeNet-5, to determine which was most effective in distinguishing genuine images from AI-generated fakes.

CNNs are particularly good at analysing visual data. They function by identifying patterns, textures, and other features that may not be visible to the human eye. Although newer models like ResNet-50 are often assumed to be more powerful due to their increased sophistication, the researchers found that LeNet-5, a comparatively basic model developed in the 1990s, initially performed best.

The team was able to enhance this CNN through architectural fine-tuning and parameter optimisation, so that their modified version of the LeNet-5 model could reach almost 96 percent accuracy. It also had a demonstrable Area Under Curve (AUC) score of almost 99 percent, meaning that statistically it performed well across a range of test scenarios. It is worth noting that this system does not rely on prior knowledge about an image's content nor the embedded metadata.

Of course, as researchers are developing the tools to detect the fakes, so those who develop the tools to create them in the first place will respond with increasing sophistication to outwit the detectors.

A newly developed performance evaluation system can assess energy storage power plants (ESPPs) in terms of investment decisions and public policy, as well as their place in sustainable energy infrastructure. The research is discussed in the International Journal of Power and Energy Conversion.

A longstanding and well-known bottleneck in sustainable energy integration is how to reliably and comprehensively evaluate the complex trade-offs involved in operating electrochemical energy storage systems, rechargeable batteries, in other words. Energy storage is critical to stabilizing supply when the power sources are unpredictable, such as solar and wind.

To investigate the issues, the researchers have used a refined version of a computational tool known as NSGA-II, or Non-dominated Sorting Genetic Algorithm II. NSGA-II is a well-established multi-objective optimization algorithm commonly used in engineering and operations research. It is particularly suited to problems with multiple, often conflicting goals, for example, maximizing system reliability while minimizing cost. The novelty in this research is that the team has overcome some of the limitations of standard versions of NSGA-II. In their approach they have extended the algorithm so that it does not settle prematurely on suboptimal solutions, local optima and instead explores all possible outcomes.

This enhancement was achieved first by introducing a new method for selecting the algorithm's starting conditions, its initial population, and secondly by replacing the conventional crossover mechanism with a more exploratory alternative. These enhancements led to an algorithm that was up to five times faster than its predecessor and demonstrably more effective at identifying better solutions across a wider range of scenarios.

The team was able to demonstrate improvements over earlier algorithms in terms of technical performance and economic and investment viability. For instance, one scenario modelled in the study suggested that under specific operational conditions, annual returns on investment in ESPPs could be as high as 13 percent. These findings suggest that, with careful system design and coordination, ESPPs can offer compelling financial incentives in addition to their environmental benefits.

As Europe's ageing population triggers a wave of business ownership transitions, research in the International Journal of Management and Enterprise Development has looked at one of the often-overlooked aspects of business, the factors influencing whether small and medium-sized enterprises (SMEs) can survive such transitions in terms of exit strategies and succession planning.

The researchers studied more than 1200 SMEs and their owner-managers in Finland, all aged 55 or older. They found that planning for the future plays a decisive role in whether firms remain innovative and adaptive as their founders prepare to step down. The research examines how different exit strategies, particularly family succession versus selling to a third party, relate to what ambidexterity. This two-handed ability to exploit existing capabilities while also exploring new opportunities.

Indeed, ambidexterity is widely regarded as essential for a company's long-term viability, particularly in a rapidly changing business landscape. However, achieving it is particularly challenging for SMEs, which often depend heavily on the personal involvement and judgement of a single owner-manager. Without deliberate planning, many small businesses risk stagnation, or even closure, when the boss steps down.

The study's key finding is that firms intending to hand over to a family member are more likely to be ambidextrous, but only if they also engage in strategic planning. In this context, strategic planning refers to a structured process of anticipating and preparing for future developments, including shifts in markets, competition, and internal capacity. Simply having the intention to keep the business in the family does not in itself translate into innovation or preparedness. It is the act of planning, systematically and proactively, that can unlock the firm's ability to balance continuity with change.

In contrast, for businesses with low or no strategic planning, the chosen exit route, whether a family succession or selling to a third party, had little effect on forward-looking or adaptable the business was. This underscores the researchers' argument that the mere expectation of a transition is not enough; it must be accompanied by intentional efforts to chart a path for the firm's future.

Operational efficiency often leads to environmental compromise in solid waste management. An approach discussed in the International Journal of Applied Decision Sciences proposes an innovative approach that could improve the collection and transportation of municipal waste. The researchers have turned to the Plant Propagation Algorithm (PPA), a nature-inspired computational method, for a different perspective on routing waste collection vehicles.

Urban sanitation services need vehicles to traverse the city as efficiently as possible. But, working out the schedules and routes many vehicles need to take is no simple planning matter. Vehicles obviously have limited waste capacity, traffic conditions vary, and there are collection time windows with which to contend in terms of access. Moreover, all vehicles need to offload their waste several times on a single shift.

As urban populations grow and waste volumes rise, solving this logistical puzzle becomes increasingly difficult, especially using conventional logistics-planning methods. Many of these traditional approaches are heuristic in nature, which means they are essentially rule-of-thumb. Metaheuristics on the other hand used advanced algorithms based on biological or physical processes. These can efficiently search large sets of possible solutions to find the most viable ones.

The Plant Propagation Algorithm stands out among these tools. It draws its logic from the way strawberry plants reproduce: by sending out runners, some explore nearby soil, others venture further afield, to find ideal growing locations for new plants to grow. This metaphor is converted into a computational search strategy that can balance local and global exploration in the space of potential vehicle routes.

The team created benchmark scenarios using the algorithm and determined performance against criteria such as total distance travelled, fuel usage, the number of vehicles required, and driver working hours. The algorithm was able to generate feasible solutions despite the complexities of urban waste systems anc could handle variable service schedules, diverse waste types, and geographically irregular service zones.

Research in the International Journal of Postharvest Technology and Innovation has demonstrated that the knowledge, attitudes, and practices of farmers and traders play a central role in determining how much food is lost after harvest in Kenya's bean supply chains. The insights from the research could have an important effect on food security initiatives across Sub-Saharan Africa.

The research, conducted in Kajiado and Kitui counties in Kenya, examined the supply chains serving the country's Home-Grown School Meals Programme (HGSMP), which provides essential nutrition to schoolchildren using locally sourced food. The focus was on common beans, a crop grown by more than three million small-scale farmers in Kenya and a vital source of protein and nutrients in the region.

While food loss in Sub-Saharan Africa is often discussed in terms of inadequate infrastructure or the impact of pests and diseases, this study turns its attention to human behaviour and specifically knowledge, attitudes, and practices. These include basic yet essential actions such as drying beans properly prior to storage, turning grains during drying, and covering them at night to protect from moisture. Each of these practices can make a measurable difference in preserving food quality and quantity.

The study found that farmers who knew and applied good post-harvest practices saw losses reduced by up to 15%. For traders, proper drying techniques led to nearly 30% less spoilage. Even attitudes, such as the willingness to adopt such drying practices, had a significant effect. The evidence suggests that behavioural change, informed by targeted education and training, could have as much impact as technical interventions such as improved storage facilities.

This shift in focus has implications across Sub-Saharan Africa. As governments and development agencies invest in reducing food loss to address hunger and improve food security, this research shows that equal weight must be given to human behaviour as to infrastructure or technology. In contexts where resources are limited, improving what people know and do may offer a more scalable and cost-effective solution than simply ploughing in more money where it is available.

Research in the International Journal of Data Mining and Bioinformatics discusses a new approach to demand forecasting for the pharmaceutical retail sector based on an artificial intelligence model. The findings hold promise for improving accuracy in one of the industry's most persistent logistical challenges: managing sales that swing sharply during promotional periods. The new system works better than traditional models by distinguishing between routine demand and the short-term surges driven by marketing campaigns.

The team has built their forecasting system using a machine-learning framework known as the Temporal Fusion Transformer. This deep-learning model is designed specifically to analyse time-series data, such as daily sales figures or seasonal illness rates. Where conventional systems might smooth over the spikes and troughs in this kind of data, the new model can interpret such fluctuations and offer a more nuanced analysis for more reliable forecasting.

One of the underlying factors leading to this improved approach is the model's use of multivariate feature construction. This method can be used to integrate diverse types of data into a single analytical framework. Rather than relying solely on historical sales figures, the model can use public health trends, seasonal disease prevalence, and promotional calendars. By working with such an enriched dataset, the model can detect complex patterns and anticipate demand with much greater precision.

In addition, the system uses a knowledge-guided attention mechanism. This process allows the system to prioritize the most relevant data depending on the sales scenario. For example, during an outbreak of influenza, the model may focus more heavily on regional health reports, whereas during a promotion, it shifts emphasis toward marketing schedules and in-store behaviour. This flexibility allows it to treat routine and promotional demand as fundamentally distinct processes, and so make better predictions about demand.

The researchers have tested their system on data from over 1.2 million retail transactions. The model reduced forecasting errors by almost a quarter compared to traditional methods. When tested in a commercial setting, it led to an almost one-third improvement in medication stock availability and just over a quarter reduction in excess inventory. Such improvements are not merely operational gains. Both outcomes are central to ensuring access to essential medicines while minimising waste in pharmaceutical supply chains.

A new data-driven technique for obstacle avoidance in autonomous vehicles is reported in the International Journal of Vehicle Design. The approach might overcome many of the longstanding challenges in the development of self-driving navigation.

Obstacle avoidance refers to the ability of a vehicle to detect and manoeuvre around objects in its path. Despite years of development, many systems still struggle with this core capability, often producing inefficient routes, reacting slowly to sudden changes, or failing altogether in complex or unpredictable environments. The new method addresses these shortcomings by integrating advanced data mining and optimization algorithms into the vehicle's navigation process.

The researchers explain that multidimensional data mining is key to their approach. This involves extracting patterns from a wide array of data sources, including visual input from cameras, spatial measurements from LIDAR (light detection and ranging, a laser-based system for mapping distances), location data from GPS (Global Positioning System), and real-time traffic information.

This data is processed using K-means clustering, a machine-learning algorithm that groups similar data points without needing prior labels. The purpose is to allow the vehicle to interpret its surroundings more intelligently, recognizing patterns such as obstacle types, road features, or the movement of nearby objects.

Once the environment is processed, the vehicle builds what researchers call a target function. This is a mathematical model that balances the goals of safety, speed, and efficiency. To optimize this function, the team applies the Whale Optimization Algorithm (WOA), a method inspired by the foraging behaviour of killer wales, Orcinus orca. WOA excels at quickly identifying optimal solutions in complex spaces, making it well suited to the high-speed demands of on-road decision-making.

In their simulations, the team demonstrated an obstacle-avoidance success rate of almost 99 percent, with reaction times as fast as 0.44 seconds. These results represent a marked improvement over many existing techniques, which often require longer processing times and produce less direct or more conservative paths.

A new approach that might improve the evaluation of college-level English teaching by incorporating a broader range of data sources could address longstanding concerns about the subjectivity of traditional assessment methods. Conventional evaluations often rely predominantly on surveys and test scores, which provide limited insight into the complexities of teaching quality. The new approach, discussed in the International Journal of Reasoning-based Intelligent Systems, instead integrates diverse forms of data, multimodal elements, to produce a more objective appraisal.

Multimodal elements encompass different types of information beyond text, including images and audio recordings related to the teaching process and student feedback. The study's main innovation lies in its use of an advanced computational framework that simultaneously analyses these varied data types, thereby capturing a more complete picture of the teaching environment.

A sophisticated algorithm, known as Cross-modal attention mechanism (CMAM), is used to identify meaningful relationships across modalities. For instance, it can link emotional expressions found in written comments with corresponding tones in audio or facial cues in images. This cross-referencing allows the system to interpret feedback in context, rather than treating each factor in isolation.

To bring information from the different modalities together, the system employs a gating mechanism. This regulates the contribution of each data source, ensuring that the most pertinent details have the most influence on the final evaluation. The combined data is then processed through a Transformer model, a machine-learning system that can understand complex patterns in language and context.

The model then performs sentiment analysis, which automatically detects the emotional tone behind the evaluations, whether positive, negative, or neutral. Unlike basic scoring, this method captures the subtleties of attitudes toward teaching quality, offering a richer understanding of student perspectives. A weighted naïve Bayes algorithm is then applied to come up with an overall evaluation score. Overall, this approach ensures the final assessment reflects not only what is said but also how it is expressed emotionally.

The Swedish mining industry, previously associated with a relative high accident rate, has seen a notable shift in its approach to safety in recent years. The lessons it has learned may help other high-risk sectors around the world improve their safety record. Research in the International Journal of Mining and Mineral Engineering has used internal records from six Swedish mining companies to help develop a new framework for evaluating safety performance. The new approach prioritizes everyday safety practices over retrospective accident statistics.

Traditionally, safety performance in mining has been assessed reactively, by counting incidents and injuries. While such metrics are clear and easy to track, they provide a limited view. They tell us what went wrong, but not necessarily what was done to prevent it. The study argues that this reactive model overlooks crucial indicators of risk and resilience, particularly in complex environments where threats may be hidden until a failure occurs. A proactive model is needed.

The proposed framework focuses on the organisational and human systems that shape safety on a daily basis. These include how companies structure safety responsibilities, how they educate their workers and managers, and how they engage employees in identifying and addressing risks. By examining all of these elements, the study suggests, organisations might gain a much clearer picture of their safety readiness, before accidents happen.

Safety management structures and leadership roles are not just bureaucratic arrangements, the researchers assert, they are active mechanisms that influence how risks are perceived and managed on the ground. Effective safety leadership requires clear communication channels, defined responsibilities, and a culture of trust, where employees feel empowered to speak up about unsafe conditions or procedural flaws.

One of the study's central insights is that safety is not purely a technical problem. Rather, it is deeply social. The ability of a company to adapt to new risks, whether posed by emerging technologies or changing work patterns, depends heavily on its internal culture. Do employees feel they have a voice? Is safety treated as a shared responsibility? Are there mechanisms in place to learn from near-misses or unexpected disruptions?

This emphasis on the "social fabric" of safety represents a significant departure from older models that treat safety management as little more than a checklist or compliance exercise. The researchers point out that while social factors are harder to quantify than, whether everyone is wearing their hard-hat and safety boots, they are no less critical. In fact, they are often what determine whether technical measures are followed, or whether they can be adapted quickly under changing conditions.

The study also highlights a broader challenge facing industries that rely on complex technical systems: the detection of latent risks—problems that may not surface until multiple small failures interact in unexpected ways. As mining operations become more automated and digitised, traditional safety metrics struggle to capture these hidden vulnerabilities. In this context, the researchers suggest that companies need more adaptive tools that can account for the dynamic nature of modern work environments.
