The main objective of recommender systems is to assist users in overcoming the issue of information overload by providing them with a carefully selected list of items that they are likely to find useful or relevant. Recommender systems may face many limitations and challenges, such as the cold start problem, which occurs when there is insufficient or no information about a new user or item. This leads to a decline in the performance of the recommender system. In this paper, we propose a recommendation system based on textual reviews and the deep learning method (RS-TRDL) to alleviate the user cold-start problem. Our RS-TRDL model can extract the important aspects and underlying sentiment polarity classification from the review text using

This study is concerned with the unsteady flow of non-Newtonian, viscous, incompressible fluid in a curved pipe with rectangular cross-section, under the action of pressure gradient. An orthogonal coordinate system has been used to describe the fluid motion and it is found that the motion equations are controlled by three parameters namely; Dean number, non-Newtonian parameter and frequency parameter. Solution for the secondary flow and the axial velocity are droved as perturbation over straight pipe. Firstly the expansion was in terms of Dean number and secondly in terms of frequency parameter. Perturbation equations are solved by using variation method namely, Galerkin's method, after eliminating the dependency on time. The solutions h

The significance of media alerts in influencing public perception and response during disease outbreaks is of paramount importance. This research investigates how media alerts affect the epidemiological model by taking into account both asymptomatic and symptomatic cases. Media alerts serve as a powerful tool for raising awareness about the disease, driving people to undergo testing and diagnosis, and promoting adherence to public health measures. This, in turn, contributes to better reporting and surveillance of cases, leading to a more accurate representation of disease spread in the model. The proposed model introduces a five-dimensional compartment system that includes susceptible, asymptomatic, symptomatic, recovered populations and

The privacy, confidentiality, and integrity of user information are very important concerns; therefore, cryptography is the solution to keep and satisfy these objectives. Encryption is the most important policy that is used to make transmitted messages have a high level of security and be so difficult to crack by attackers.
