Spectrophotometric Determination of Mebendazole in Pharmaceutical and Urine Samples by a New Flow Injection with Merging-Zone Technique
...Show More Authors

Accurate determination of Mebendazole in pharmaceutical formulations is essential for ensuring drug quality and monitoring therapeutic efficacy in humans. Therefore, a new technique for detecting the antifungal medication mebendazole was developed. This method utilizes flow injection analysis with merging zones, offering a quick, straightforward, and highly sensitive approach to quantifying the drug. The method relies on mebendazole to reduce iron III to iron II under acidic conditions. The reduced iron then reacts with 1,10-phenanthroline to form an orange-red colored complex measured spectroscopically at 510 nm. The method showed a linear correlation between response and concentration over 25-250 µg/mL, with 22 and 25.5 µg/mL LOD and

Improving Security in Wireless Sensor Networks: A New Key Pre-Distribution Approach with Taylor Series
...Show More Authors

Ensuring robust authentication is essential in Wireless Sensor Networks (WSNs) to protect sensitive data transfer between nodes. This paper proposes the use of mathematical implementations to enhance the security and complexity of secret data transmission between nodes, thereby providing a robust communication system. Additionally, it proposes a new mathematical implementation as an authentication model based on the Taylor expansion sequence. This strategy allows secure communication between any two nodes to prevent the malicious node from stealing the data or hacking the secret information from any node on the network. The proposed solution is based on unique parameters carried by any two communicating nodes in the network. These nodes

Load Balancing on Virtual Machines Using Levy Flight Combined with Gray Wolf Optimization Algorithm
...Show More Authors

In a cloud computing environment, virtual machines must be allocated wisely among queued resources waiting for a specific service. In this case, the optimal load balancing on those virtual machines must be done using optimization methods. Because the distribution of processes on the VMs is considered one of the NP-Hard optimization problems, it is necessary to use optimization methods. This paper proposes a hybridized Gray Wolf Optimizer (GWO) and Levy Flight (LF) search approach. The proposed method is called Levy Flight-GWO-Virtual Machine Load Balancing (LF-GWO-VM-LB). Despite the success of the standard GWO alone as a load-balancing method, it needs to improve its explorative capability and premature convergence. Levy flight is an id

Secure and Robust Watermarking Using NSST-LWT-DCT-SVD for Copyright Protection
...Show More Authors

The ongoing issue of unauthorized image distribution poses a serious modern challenge. This research introduces an innovative dual image watermarking technique that determines a potential embedding area in a small 4×4 DCT block and employs a hybrid approach of NSST-LWT-DCT-SVD to ensure efficient copyright protection. The watermark images are integrated using the red and green channels. These channels are then transformed using NSST-LWT to extract the low-frequency sub-band. Following this, the low-frequency section is divided into 4×4 blocks. The Human Visual System (HVS) is then used to select the appropriate blocks, which are transformed using DCT. Certain coefficients from the middle frequency of the DCT are chosen for decompositio

Optimizing Security and Response Time of Relational Database Using Moth-Flame Algorithm
...Show More Authors

Query optimization in relational databases is a costly process, and the number of different permutations of link operations for a query grows exponentially as the number of tables in the query increases. Current query optimization techniques are unsuitable for use in cases where the number of database tables and the number of rows in each table are large. On the other hand, the key to the success of a database system is the efficiency of its query model. Therefore, this research proposes a method for optimizing query execution by rearranging query structures.

Due to the increasing importance of reducing the execution time of the optimal design in the connection operation with a large number of tables and minimizing the execution t

An Intensive Study of Finite Dimensional Hesitant Fuzzy Normed Linear Spaces
...Show More Authors

The author's previous covered the concept of fuzzy normed linear space into hesitant fuzzy normed linear space. This work introduces hesitant fuzzy n-normed linear space as a generalization of n-normed space in addition to the generic t-norm, which is the major objective, and provides an expanding family of S*-n-norms that correspond to fuzzy n-norms. The decomposition theorem of a hesitant fuzzy norm into a set of crisp norms has been proven to fail when a t-norm other than "min" is used. This paper also addresses essential conclusions for fuzzy normed linear spaces of limited dimensions within a broad t-norm framework.
