Weed detection is a challenging case within object detection as the weed targets do not generally strike out from the background in terms of color. This paper investigates how the density of structural features can be used to assist the training process of a Deep-Learning-based object detector. SIFT keypoint density is used to create overlay masks to augment images, emphasizing low-density areas-typically corresponding to weed plants. Our method is shown to improve detection mAP. 5:.05:.95 on the YOLOR-CSP detector by up to 0.0215.

As we venture further into an ever-evolving digital society, it has become imperative for schools to adapt and equip future generations with the required skills. Computational Thinking (CT), specifically its algorithmic thinking aspect, plays a significant role in computerscience and other sciences, such as biology, chemistry, and physics. It encourages students to reason at multiple levels of abstraction. This ability is particularly useful in natural science, as scientific experiments require critical skills like conceptualization, problem decomposition, and solving or designing structured systems. However, due to organizational and curricular restrictions, these concepts and skills are typically taught separately, leaving it to the learners to connect and apply the acquired skills in the respective context. To bridge this gap, we designed a two-day workshop that embeds CT in a physics and sustainability context, namely energy-efficient housing. In this workshop, we employ the Calliope Mini, a micro-controller explicitly designed for educational purposes, to teach essential algorithmic thinking and data processing. We carried out the workshop twice in a primary school in Germany, each with 20 children in 4th grade (ages 9-10). In this experience report, we present the multi-disciplinary workshop idea and discuss the outcome and observations from its execution. Overall, our study demonstrates the potential of such a workshop design as a practical tool for teaching CT concepts to children. Finally, we critically examine the challenges of this approach and highlight the importance of proper technical and educational prerequisites for a successful implementation.

Due to a rising number of entities and more advanced systems, modern air combat engagements are increasing in complexity. Therefore, to ensure success in pilot training and perform accurate threat evaluation using simulations, it is substantial to not only replicate and simulate the physical properties of the computer-Generated forces (CGFs) to an adequate degree but also to provide them with sufficiently realistic, coordinated and situation-adaptive behavior. Additionally, most air combat research assumes that all aircraft information is known, however, in real-world scenarios, multiple factors, such as sensor performance limitations, can lead to missing or incorrect information about the position, altitude, or velocity of adversary aircraft. In this paper, we propose a Tactical Planning Process as part of an overarching CGF Team Behavior Agent Function utilizing information such as threat risk and the enemy's intent from a Situation Analysis created with realistically available data. This process is partitioned into two stages, Team Planning and Maneuver Selection. Team Planning consists of deciding whether the mission itself should be commenced or aborted, selecting Tactics to counter the threats, as well as performing a Targeting in which threat aircraft are assigned to the individual CGFs. Further, in Maneuver Selection, the own current risks are assessed and used to continuously decide the current task for each CGF with respect to its target. Following, the maneuver command itself is being selected and sent to the simulated aircraft. This is done within an evaluation of the own chances and risks by, in a first step, identifying suitable tactical maneuver types, in a second step, narrow down their parameters, so that, in the final step, predicted risks from the Situation Analysis can be incorporated in the selection process as well. We employ Behavior Trees to guide the CGFs through these different tasks, while repeatedly assessing the developing risks to be ab

In today's life, humans compromise with nature while evolving into a more advanced species. One of the main effects of that advancement is air pollution. Air pollution seriously threatens human health, the environment, and the general quality of life worldwide. A quantitative analysis of air quality was the purpose of developing the Air Quality Index (AQI), an indexing approach. The air quality index is computed usingmeasurements for particulatematter (PM), PM2.5, PM10, NO2, CO, CO2, NH3, and other contaminants. Agnihotra (Yagya) is a method of environmental purificationmentioned in the Hindu sculpture (TheBook Yagya Vimarsh, written by Dr. Ramprakash, talks about the air pollution reduction method). This paper discusses the Vayu Vishleshan framework for monitoring air quality in the presence of Agnihotra (Yagya). This study is divided into two processes. The first one is AQI monitoring, and the second is AQI reduction. AQI Monitoring covers sensing particulate matter (PM), PM2.5, PM10, NO2, and CO and performing analysis over theAQI data before, during, and following Agnihotra (Yagya). According to analysis, there is an approximate 6-7% decrease in CO levels and an approximate 10-12% decrease in PM levels following Agnihotra.
