Assessing Urban Heat Islands Using GIS and Remote Sensing for Sustainable Urban Planning in the Philippines
Abstract- Growing urbanization and a tropical climate intensify the known environmental challenges of urban heat islands (UHIs) in the Philippines. UHIs are formed by human activity, infrastructure, and decreased vegetation, resulting in elevated temperatures in urban areas compared to their rural surroundings. This tendency exacerbates energy consumption, air pollution, and health concerns, posing significant issues for urban planners and policymakers. Geographic Information Systems (GIS) and remote sensing technologies provide efficient methods for evaluating and reducing UHIs. GIS enables the merging and examination of geographical data, providing a comprehensive understanding of urban settings. Remote sensing uses thermal data from satellites to provide a comprehensive understanding of land surface temperatures and heat distribution patterns. In the Philippines, these technologies are essential for detecting areas with high temperatures, assessing the elements that contribute to this, and creating specific policies for sustainable urban development. By utilizing GIS and remote sensing, urban planners can strategically create geographically accurate green spaces, optimize construction materials, and apply cooling measures, ultimately fostering a healthier and more resilient urban environment. This paper shows the significant utilization of these technologies to facilitate data-driven decision-making, which is crucial for mitigating the detrimental impacts of UHIs. This research can guide environmental planners on how to utilize GIS and remote sensing for a more scientific approach as urban areas continue to grow and science-based sustainable urban planning becomes more and more apparent. Evaluating UHIs using GIS and remote sensing is an essential step in the development of habitable, sustainable, and climate-resilient cities in the Philippines.

Abstract: An up-to-date review of erosion-corrosion from various literary sources, covering its origin, impacts, affecting factors, occurrence areas, experimental measuring devices, and research advances, is reported. From the review, erosion-corrosion is a mechanically caused action by impinging fluid, usually liquid, slurry abrasion, suspended particles in fast-flowing fluids, bubbles, droplets, cavitations, etc., under complex synergistic effects of the natural electrochemical corrosion. It is affected by many factors that still need to be fully understood, so it is very challenging to accurately find its rates for controlling it. It is a very costly problem that is common in power plants, water, oil, gas, metallurgy, mining, and other industrial sectors that utilize mechanical equipment as well as structural components in hydraulic environments. Its effects are predominant in petroleum pipelines and heat exchange industries, as well as marine equipment or structures. Its rates, time scale, and capacity to degenerate material components to failure are much more alarming than most other corrosion types. This corrosion type is highly detestable, so much attention has been drawn to it, as attested by many research outputs on it to date, with a pressing need for ways, including emerging technologies, of minimizing its impacts. Forty-six of the research outputs have been recapitulated and presented, and they focus on developing and/or testing alternative material components, coatings, measuring devices, and application of artificial intelligence, for better erosion-corrosion resistances or rate measurements and control under various fluid conditions. The paper provides integrated, up-to-date information on erosion-corrosion for easy accessibility for the needful basic knowledge for research progress towards reducing its impacts.

Utilization of Palm Kernel Shell as Coarse Aggregate Replacement in Pervious Concrete: An Alternative Approach to Sustainable Pervious Concrete Walkway
Abstract: Increased urbanization in many cities of the world brings with it the problem of multiplied impervious surfaces on infrastructure like roads. Using pervious instead of impervious surfaces will address these concerns, the use of palm kernel shell (PKS) to replace granite in the matrix will further address the cost and environmental worries. A Pervious Concrete walkway was constructed on an unpaved, waterlogged stretch using agricultural waste product-Palm Kernel Shell (PKS) to replace conventional granite in the concrete matrix. The initial laboratory tests were carried out in accordance with BS 812, Part 101 from 1984 to 1990, and Parts 110 and 112 from 1990. The batching process was weighted, with aggregate percentages for partial replacement set at 10%, 20%, 30%, 40%, and 50% PKS. The mix of 70% granite and 30% palm kernel shell produced the highest compressive strength, with values of 5.33 MPa, 6.19 MPa, and 7.36 MPa at 7, 14, and 28 days, respectively. The incorporation of PKS into the pervious concrete walkway effectively reduced waterlogging in the area while posing no environmental concerns..

Energy Detector with Adaptive Optimal Threshold for Enhancing Spectrum Sensing in Cognitive Radio Network
Abstract: Cognitive radio (CR) is a promising solution to resolve the crisis of spectrum underutilization. Spectrum sensing is an indispensable aspect of CR network (CRN). Energy detection method is being recognized as a simple and reliable step for spectrum sensing. The significant factor of the energy detector (ED) is threshold, whose optimum value depends on signal to noise ratio (SNR). However, in a wireless environment, where the received signal is severely degraded due to the uncertain noise, reliable spectrum sensing is not guaranteed.
The key metrics of the CRN are total spectrum sensing error probability, throughput, and energy efficiency. For each SNR value, there exists an optimal threshold that minimizes total spectrum sensing error probability and maximizes throughput as well as energy efficiency. Therefore, the threshold of ED should be adaptive in CRN. This paper presents an optimal adaptive threshold by utilizing spectrum sensing errors for each metric in CRN.

Superiority of Composite Baseball Bats: Trampoline Effect, Acoustics, Compliance and Safety
Abstract: The superiority of composite (blended/multiple materials) baseball bats over wood bats, bolstering 10-15% higher exit velocity is attributed to the trampoline effect (bounciness) resulting from advanced materials, deliberate breaking, reduced sting vibrations, balanced weight, and an expanded sweet spot. This article systematically examines (B7: Bolstering (enhanced), Blended (composite) Baseball Bats with Bounciness, Bang (sound), and Banishment (safety), focusing on the comparative superiority of composite bats over wood bats for 12U players, where they are permitted. In a controlled environment (70 oF), the average exit velocity of a ball on the composite bat are >10% superior to those of a wood bat when hitting balls off the tee, while >15% superior when hitting balls pitched at a speed of 50 MPH. Experimentally, metal bats produced a louder (102 to 106 dB), high-pitched “bang” due to their hollow structure, while composite and wood bats emitted a quieter (91 to 95 dB), low-pitched sound, when measured close to the batter. The variation in decibels was influenced by ball speed, impact point, and bat design, affecting player perception. Composite bats gain power over time as they break in, enhancing performance but also introducing inconsistency and potentially increasing injury risk. Authors shed light on the importance of baseball safety gear for players on the diamond, helping them avoid possible injuries.

Sentiment Analysis for Movie Database Management System Using Naive Bayes Algorithm
Abstract: According to F. Furtado and A. Singh (2021), movie recommendation systems aim to assist viewers by suggesting movies to watch, thereby avoiding the time-consuming and complex process of selecting from a vast library of movies, which can number in the thousands or even millions. This article seeks to reduce human effort by recommending movies based on user interests. To address these challenges, we propose a technique that combines content-based and collaborative approaches. This method produces more precise results than systems that rely solely on content-based methods. Content-based recommendation systems are limited to individual preferences and do not recommend items outside the user’s immediate interests, restricting exploration. To overcome these limitations, we developed a system that addresses these concerns. The proposed movie recommendation system uses Cosine Similarity to suggest movies like the one chosen by the user. While existing algorithms generate recommendations, they often fail to answer the critical question, “Is this a film worth watching?” To enhance the overall experience, our system incorporates sentiment analysis of selected movie reviews using machine learning techniques. This study employs two supervised learning approaches, Naïve Bayes (NB) and Support Vector Machine (SVM), to improve accuracy and efficacy. A comparison of the two methods reveals that SVM achieved an accuracy score of 98.63%, while NB scored 97.33%, as reported by N. Pavitha et al. (2022).

Sign Language Recognition Using Deep Learning: Advancements and Challenges
Abstract: Sign language recognition (SLR) has arisen as a major area of research in recent years, attempting to bridge the communication gap between the deaf and hard-of-hearing community and the hearing world. This research study addresses the construction and implementation of a manual alphabet recognition system utilising deep learning techniques, notably convolutional neural networks (CNNs). The work focuses on establishing an efficient and accurate system for converting Nigerian Sign Language manual alphabets into text. By integrating computer vision and machine learning methods, the proposed system seeks to overcome the communication gap between deaf and hearing individuals. The paper explains the technique adopted, including data collection, preprocessing, model architecture, and deployment using web-based tools. The system achieves a 95% success rate in recognizing static hand motions, proving its potential for real-world applications. However, issues in identifying dynamic motions and generalizing across varied user populations are observed. The report finishes with recommendations for future research, emphasizing the need for combining temporal analysis and expanding the system's capabilities to word and phrase recognition.

Planning for the Disposal of the Dead in Federal Capital Territory (FCT), Nigeria: A Review of Literature on Challenges and Policy Recommendations
Abstract: Given that death is a natural occurrence, disposing of the dead especially corpses is an unavoidable and necessary part of human life. In order to appropriately dispose of the deceased, land use planning is crucial since improper handling could jeopardize environmental, psychological, and human health. In Nigeria, planning laws have not stopped urban growth due to urbanization and shifting societal attitudes. Public authorities usually only consider residential, commercial, industrial, and institutional land uses like schools, hospitals, and stadiums when allocating state land directly or through state agencies, despite the fact that the country's population has grown from 70 million in 1973 to nearly 200 million in recent years. The matters of death and burial require consideration from both a general and an urban management and planning standpoint. The development and execution of environmental policy on the disposal of the deceased should be localized, taking into account the characteristics of residents in certain areas. This evaluation determined that the living's planning for the disposal of the deceased encompasses creating a comfortable environment for the ultimate resting place, appropriately interring the remains, and ensuring that the subsequent management and maintenance of the designated resting area is conducted with dignity and hygiene. From a municipal standpoint, interring the deceased is regarded as an essential and obligatory public service.
