Performance Evaluation of a Double-Pass Solar Air Heater with Recycled Materials as Absorber Plate
-Vimalkumar Patel
The double pass solar air heater or DPSAH is a device that is integrated with the solar air heater in order to facilitate the transfer of heart energy from one part of the device to another part of the device so that the heart's energy can be transferred efficiently. Solar air heaters with just one pass are said to have a lesser impact on the generation of thermal energy since they lose out on the energy during the transfer process and, as a result, they generate less thermal energy. On the other hand, DPSAH exhibits a superior thermal efficiency, as this is the result of doubling the area of heat transfer, which is attributed to its energy-efficient design that allows it to achieve better thermal efficiency. The absorber plate located behind the collector of a DPSAH helps in the collection of solar energy by absorbing the light from the sun. There are many situations where a part such as this will be painted black in order to increase the absorption of solar energy, as this colour has a direct impact on the generation of a higher absorption of solar energy. It is intended that as part of the study, the use of recycled materials will be observed in the construction of the absorber plate, as well as the efficiency that is generated from the use of such materials. It should be noted that the majority of absorber materials which are usually used for this application are semiconductors or dyes, which can come in both organic and inorganic forms. Read More...

An Experimental Investigation of Plastic Fiber Reinforced Self-Compacting Concrete
-Ritika Shrivastava ; Mayur Singi
Self-compacting concrete (SCC) is a mixture that can be easily placed into formwork without the need for vibrating compaction, owing to its self-weight and high flowability. Unlike traditional concrete, SCC ensures that coarse aggregates remain uniformly distributed, eliminating the requirement for external or internal vibration during the compaction process while maintaining its engineering properties. Key properties of the new SCC include filling capacity, passing capacity, and strength, which are crucial considerations. Solidified mechanical properties of SCC with plastic fiber reinforcement are comparable to conventionally vibrated concrete. However, the disposal of waste plastics presents environmental challenges. Plastic is a non-biodegradable material, persisting in water and soil without degradation, leading to water and soil contamination. Incinerating plastic releases harmful gases, contributing to air pollution and posing health risks when inhaled. As a result, several countries have banned the use of plastics to address this pressing environmental issue. To tackle this problem, this research focuses on producing reinforced self-compacting concrete with waste plastic fibers (WPFRSCC) as a sustainable construction material. This approach offers a dual advantage, enhancing the properties of SCC while simultaneously addressing the disposal of waste plastics. In the study, a mix proportion for M40 concrete is determined using the IS: 10262:2009 method. Experiments are conducted to examine the flow characteristics of SCC with varying percentages of waste plastic fibers (0%, 0.50%, 1.00%, and 1.50%), along with different proportions of superplasticizer (1%, 0.90%, 0.80%, and 0.70%). After obtaining satisfactory mixes, cube, cylinder, and beam specimens are cast using different percentages of waste plastic fibers. Subsequent strength tests are performed on these specimens to evaluate the hardened properties of SCC with waste plastic reinforcement. The results demonstrate that waste plastic fiber reinforced SCC can be successfully developed without the need for consistency-modifying agents. Four distinct mixtures are formulated to meet the specific requirements of fresh SCC, considering different fiber percentages. From a strength perspective, it is found that an optimal combination is achieved with 1.0% of fiber content and 0.70% of superplasticizer. Read More...

Development of AI-based Detection and Classification model for Apple Crop Diseases
-Amit Kumar
In India, the valley of Kashmir holds the maximum share of Apple production with more than 75% of total apple production. Currently, around 160000 hectares of land in the Valley is under apple cultivation with an annual productivity of around 180000 MTs [source: Directorate of Horticulture, 2021], in which most part is exported to various regions of the world. Apple orchards are under constant threat from various types of viral pathogens, fungus, bacteria, and insects. They continuously damage the apple fruits and leaves, this is primary cause of low apple yield and results in a huge economic loss to the apple industry every year. Diseases like apple Scab, Apple Cedar Rust, Powdery Mildew, apple Blotch and apple Rot remain a major threat for the apple growers. Early diagnosis of apple diseases can help in controlling of infection spread and ensure higher yield, thus preventing substantial economic losses. Therefore, timely detection of diseases is crucial for enhancing both quality and quantity of apples. Traditional manual disease identification and inspection is laborious, time-consuming, error prone and requires a thorough knowledge of apple plant pathogens. Instead, automated approaches save both time and effort. In this research, , developed an AI based detection and classification model for apple crop diseases using deep learning architecture based on transfer learning convolutional neural network called YOLOv5. The model is improved to optimize for both detection speed and accuracy and applied to multi class apple plant disease detection in the real environment. The dataset corpus is formed which consists of 7909 images belonging to 6 classes namely apple scab, apple cedar rust, powdery mildew, healthy, apple blotch and apple rot. Then, the data annotation process is performed on all the images as per their target classes and saves the labels in a text file. During annotation of images in the training dataset, each text file contains information about the target class and the corresponding bounding coordinate. Several data augmentation techniques are performed to enrich and diversify the dataset which improves the model generalizability and eliminates the problem of overfitting. The non-maximum suppression (NMS) algorithm is used with darknet 53 framework. The mean average precision (mAP) and F1-score of the trained detection model is 90.22% and 92.5%, respectively. The developed model can be employed as an effective and efficient method to detect different apple plant diseases under complex orchard scenarios and can be extended to different fruit crops and automated agricultural detection processes.

Green Smart Home by Fog Computing
-Namrata Anil Sargar
IoT devices are incomplete without a cloud server. Without cloud services, we cannot collect and process the data that is sent from each IoT sensor, then execute and send back the result. Implementation of a fog node near an IoT device results in storing and processing data at the fog node rather than sending it to the cloud. This study proposed multiple sensors for a smart home that is connected to a cloud server with a fog node and without a fog node. A smart home consists of 10 sensors like motion, gas, light, vibration, location, water leak, air, video, and humidity. The evaluation is done by comparing the energy consumption and network usage of sensors that are connected to the cloud with a fog node and without a fog node. The energy consumption and network usage of sensors with fog computing are lower than without fog computing, so these will lead to a green smart home. If more sensors are added, then also energy consumption and network usage of fog computing will be lower. Read More...
