Comparative studies on inducers in the production of naringinase from Aspergillus niger MTCC 1344
This research provides detailed systematic study of the effect of different inducers (hesperidin, naringenin, naringin, rhamnose and rutin) in naringinase production by Aspergillus niger MTCC 1344. Cultures were carried out in shake flasks and they produce extracellular naringinase in a complex (molasses, peptone and salts) medium. The optimized concentration (%) of naringin, rhamnose, naringenin, rutin and hesperidin for maximized naringinase production are 0.1, 0.375, 0.01, 0.2 and 0.2, respectively. Compared with control, inducers increased the naringinase production by many folds in the order of naringin (6.63) > rhamnose (4.87) > naringenin (3.26) > rutin (2.84) > hesperidin (2.35). Under optimum conditions, about 9.68 units of enzyme per ml complex medium containing naringin were obtained on the 7th day. The activity to inducer (A/I) ratio was 968 Ug-1 naringin, and the cultivation time was shorter in submerged production. The results indicate that naringinase activity used naringin as an inducer which was significantly higher than the other four inducers. Therefore naringin is recommended for naringinase production.Key words: Naringin, naringenin, rutin, hesperidin, rhamnose, naringinase, Aspergillus, inducer, molasses

Hybrid Sine-Cosine Black Widow Spider Optimization based Route Selection Protocol for Multihop Communication in IoT Assisted WSN
In the modern era, Internet of Things (IoT) has been a popular research topic and it focuses on interconnecting numerous sensor-based devices primarily for tracking applications and collecting data. Wireless Sensor Networks (WSN) becomes a significant element in IoT platforms since its inception and turns out to be the most ideal platform for deploying various smart city application zones namely disaster management, home automation, intelligent transportation, smart buildings, and other IoT-enabled applications. Clustering techniques were commonly used energy-efficient methods with the main purpose that is to balance the energy between Sensor Nodes (SN). Routing and clustering are Non-Polynomial (NP) hard issues where bio-inspired approaches were used for a known time to solve these issues. This study introduces a Hybrid Sine-Cosine Black Widow Spider Optimization based Route Selection Protocol (HSBWSO-RSP) for Mulithop Communication in IoT assisted WSN. The presented HSBWSO-RSP technique aims to properly determine the routes to destination for multihop communication. Moreover, the HSBWSO-RSP approach enables the integration of variance perturbation mechanism into the traditional BWSO algorithm. Furthermore, the selection of routes takes place by a fitness function comprising Residual Energy (RE) and distance (DIST). The experimental result analysis of the HSBWSO-RSP technique is tested using a series of experimentations and the results are studied under different measures. The proposed methodology achieves 100% packet delivery ratio, no packet loss and 2.33 secs end to end delay. The comparison study revealed the betterment of the HSBWSO-RSP technique over existing routing techniques
Integrating Ergonomic Factors with Waste Identification Diagram to Enhance Operator Performance and Productivity in the Textile Industry
Industries have introduced lean manufacturing systems to outperform their competitors and sustain their growth. The implementation of lean tools results in satisfying the customer needs. Industries focus primarily on technical assistance when implementing lean strategies, but the success and sustainability of a lean strategy largely depend on the skill and cooperation of the workers. Research findings show that most industries have not attached importance to human factors while implementing lean logic. The negligence of human factors affects the quality of life of workers. Hence, this study intends to improve the quality of life and efficiency of workers by integrating ergonomic factors with the implementation of lean strategies in apparel industry. To accomplish this, the waste identification diagram was improved by adding a component to determine operators’ performance and analyse human factors. The ergonomic-waste identification diagram has been created to identify tasks related to ergonomic investigations and analyse human factors with lean metrics.

Clustering Techniques for Recommendation of Movies
A recommendation system employs a variety of algorithms to provide users with recommendations of any kind. The most well-known technique, collaborative filtering, involves users with similar preferences although it is not always as effective when dealing with large amounts of data. Improvements to this approach are required as the dataset size increases. Here, in our suggested method, we combine a hierarchical clustering methodology with a collaborative filtering algorithm for making recommendations. Additionally, the Principle Component Analysis (PCA) method is used to condense the dimensions of the data to improve the accuracy of the outcomes. The dataset will receive additional benefits from the clustering technique when using hierarchical clustering, and the PCA will help redefine the dataset by reducing its dimensionality as needed. The primary elements utilized for recommendations can be enhanced by applying the key elements of these two strategies to the conventional collaborative filtering recommendation algorithm. The suggested method will unquestionably improve the precision of the findings received from the conventional CFRA and significantly increase the effectiveness of the recommendation system. The total findings will be applied to the combined dataset of TMDB and Movie Lens, which is utilized to suggest movies to the user in accordance with the rating patterns that each individual user has generated
