Formulation, Development and Evaluation of Topiramate Loaded Niosomes for the Treatment of Epilepsy
Topiramate (TPM) is an anti-epileptic drug used in the treatment of epilepsy and seizures. The study was designed with three aims. First, to enhance the solubility and bioavailability of BCS class III drug TPM; second, to ease administration of the formulation to the epileptic patient, during an attack, and third, to decrease the dose of drug for enduring treatment. Formulation of TPM niosomes was optimized by changing the concentration of Tween, Labrafil and cholesterol using response surface design. Further the TPM niosomes were prepared by using ether injection method. The formulation was then evaluated for vesicle size, entrapment efficiency and in-vitro drug release study. FTIR and DSC studies were performed for pure drug and optimized batch. The vesicle size of the optimized batch was found to be 0. 35 nm. The %entrapment efficiency and %drug release of optimized batch was found to be 94.64% and 92.027% respectively. From the present study it can be concluded that the developed niosomes of TPM has shown great potential in treatment of epilepsy
Trusted Net: A Lightweight Cluster-Based Trust Sensing System for IoT Networks
Abstract— The Internet of Things is founded on the premise that objects in the human living environment can be connected to the Internet. Adoption of the Internet of Things cannot be permitted until security issues are addressed. Security solutions for the Internet of Things can be built on unique designs such as partitioning a mobile network into clusters managed by a cluster head, often known as clustering. However, without any security considerations, the clustering process is vulnerable to a variety of security-related internal attacks. A trust management system, which has proven its security efficiency and friability in mobile networks, might be used to defend the IoT against rogue nodes within it. In this research, we provide a trust-based clustering technique for the Internet of Things. Trust Sensing has played an important part in dealing with security concerns. A novel Light Weight Clustered Trust Sensing (LWCTS) Mechanism has been created with the primary goal of reducing The amount of energy that IoT nodes use. The LWCTS first clusters the network and chooses highly resourced Cluster Heads. Additionally, two components are considered in the proposed trust model: the mobility component for trust sensing and the interactive trust factor. The primary purpose of mobility factor inclusion in the network is to reduce the number of false positives.
 
Countryside leaf extracts act as an Eco-friendly natural pesticide
Present research discusses how countryside leaf extracts act as reasonable pest control for different crops, vegetables, fruits, flowers. Many modern pesticides are used today to store toxic materials in soils, air, and water. These toxin materials affect plants, animals as well as human health. These are also non-biodegradable in our environment. These leave extracts are toxic to insects pests. For this purpose, we collect Neem leaf, Indian Bael leaf, Green Chiretta leaf. After preparation of leaf extracts and uses of different crops, it may be concluded that the decreasing order of the pest control of natural leaf extracts is a Mix of all three leaves>Neem leaves> GreenChiretta> Indian Bael. Elico(171, Mini Spectro) machine was used to characterize these leaf extracts. Especially this pesticide uses on potato field to protect Aphids in West Bengal. Using these natural pesticides, after 2 week 95% Aphids were died.
 
An Isolation Detection Technique for Distributed Generators Based on Inverter for Power Quality Improvement
In the present paper, an isolation method of detection for the inverter-based system of Distributed generators is proposed and based on perturbing output of reactive power. In the proposed method two sets of the disturbances are designed and have different magnitudes and time durations. In the primary set of reactive power disturbance, amplitudes are periodic and small to break reactive power balancing during isolation process. The secondary set of reactive power disturbance is required for deviation of the frequency beyond its threshold limits. The characteristics of the frequency variations with primary set after isolation are considered and three criterion are designed for switching the disturbances from primary set to secondary set of RPD. All the DGs which are located at different positions have same variation in frequency characteristics and primary set of RPD can be added to different DGs without any further communication at the same instant. Here, synchronization of the secondary set of disturbances can be guaranteed for a system with the multiple DGs. The proposed method is applied to DGs which operate at UPF or for supplying of reactive power to the local loads and the method is validated with cases mentioned in the Matlab/Simulink environment
Performance Evaluation of Approximate (8; 2) Compressor for Multipliers in Error-Resilient Image Processing Applications
Abstract
Approximate computing improves performance in error-resilient applications like image and video processing. Multipliers are part of its computing unit, which frequently requires a large number of resources. This study compares an approximation (8; 2) compressor to other known models in terms of quality, power consumption, delay, and circuit area. The proposed approximation compressor is implemented in 8 × 8 and 16 × 16 multipliers. To demonstrate the quality of the suggested compressor, an 8 × 8 approximation multiplier was utilized to multiply two images in MATLAB tools. Qualitative measures such as SSIM and PSNR were examined and acceptable results were obtained. The suggested 8 × 8 multiplier circuit produces an acceptable error rate, as indicated by the MED and NED accuracy criteria. Finally, we used a Synopsys Design Compiler to synthesize the proposed approximation compressor and multiplier designs. The suggested 16 × 16 multiplier improves latency, area, and power delay products by 5%, 17%, and 8%, respectively, compared to similar current approximate multipliers.
 
Identifying Product Aspect Polarity by Product Review Classification with Dual Sentiment Analysis
Dual Sentiment Analysis has emerged as a crucial and active research field. It involves extracting sentiment from comments, feedback, or critiques, which serves as valuable indicators for various purposes. To address this, we propose a novel dual training algorithm that utilizes both original and reversed training reviews to develop a robust sentiment classifier. Additionally, we introduce a dual prediction algorithm that comprehensively assesses both aspects of a review for classification during testing. The proposed approach goes beyond traditional polarity (positive-negative) classification by extending the framework to a 3-class system, which includes neutral reviews. This enhancement allows for a more nuanced understanding of sentiment. By considering neutral reviews, we gain deeper insights into the sentiment landscape. Dual Sentiment Analysis plays a pivotal role in helping companies gauge the level of acceptance of their products and formulate strategies to improve product quality. Moreover, it empowers policymakers and politicians to gain valuable insights by analyzing public sentiments on policies, public services, and political issues
