To do this, local communities can reuse resources like food that may be close to expiring in restaurants, stores, and food distribution facilities as well as any perishables that aren't consumed entirely within their intended shelf life. This is very important, especially in times of crisis like the COVID-19 pandemic. This study focuses on developing a fascinating initial webapp called CHERISH that offers a universal platform where users may visualise available resource resources in their neighbourhood and afterwards acquire access to resources, so addressing two key challenges, namely hunger and resource waste. This platform meets the broad category of AI for and is relevant to the UN SDGs (United Nations Sustainable Development Goals).

And some of the sectors have sensitive data, for example, Military, Agencies, Colleges, Industries, etc. The data can be retrieved when the user requests it. And others can also access the data. Cloud computing provides a lot of features with affordable prices and knowledge accessibility by using the Internet. Security is the main concern in the cloud computing environment as clients store secret information with cloud providers, but sometimes these providers may not be trustful. Splitting data in a safe approach while protecting data from an untrusted cloud is still a demanding topic. In this paper we ensure the right approach for data security and privacy, using Blowfish, and RSA/SRNN algorithms.

A communication satellite is basically an electronic communication package placed in orbit whose prime objective is to initiate or assist another through space. This paper will explain overview of satellite communications, its working, types of satellites and services provided by these communications. This communication further includes satellite orbits and their comparison. We had also discussed satellite merits and demerits which made this communication successful along with its applications in today world (usage). New invention satellites are also discussed.

This technology enables the user to deploy a computer network without needing to run cable throughout the facility. In recent years, wireless networking has become more wide, accessible, inexpensive, and user-friendly. Home users are adopting wireless technology in huge numbers. Up and about laptop users often find free wireless connections in places like coffee shops and airports, also known as hotspots. This paper will explain various wireless broadband technologies (WiBro) such as IEEE 802.11 and IEEE 802.16.Also we will compare technologies pros and cons individually. At last, to provide better services to customer we will review fusion of these WiBro technologies and its benefits.

There are Some issues in wsn like scalability, deployment, energy consumption and many more. There are also many energy efficient techniques in wireless sensor network like LEACH, HEAP etc. Divide and conquer is also one of the efficient technique which is based upon manually deployment. In this paper , Divide and conquer scheme is explained in detail.

Engineering applications involving mobile subsystems or just the desire to save cabling make wireless technologies attractive. Nonetheless these applications often have rigorous requirements on reliability and timing. The main aim of this paper is to simulate an environment of integrated network i.e. Wi-Fi and Wimax and investigate the comparative performance of individual environment i.e. Wi-Fi, Wimax, and an integrated Wi-Fi and Wimax with respect to QoS parameters. For this we used Ns2 and LTE tool and further proves integration shows better results.
Intelligent Load Balancing Approach for Cognitive Radio Networks

This spectrum shortage also affects channel utilization due to comparatively high congestion levels. The main reason that leads to useless utilization of the radio range is the spectrum licensing system itself. Due to this static and rigid allocation, wireless systems have to work only on a dedicated band of spectrum and cannot change the transmission band as changing the environment. One of the solutions that have been proposed to solve this critical problem is to use unlicensed devices in the available licensed bands. Therefore, dynamic spectrum access techniques based on load balancing are proposed to provide efficient spectrum utilization. In Cognitive Radio Network (CRN) a large number of very frequent connection requests from both primary and secondary user’s results in dynamic demand for a number of target channels. In this work an intellig...

In an attempt to identify modifiable risk factors for LBW in Saudi Arabia, the present research was undertaken to investigate a potential association between maternal dental health and dental care during pregnancy with LBW due to fetal growth retardation. Material & Methods: A case-control study was conducted on a group of post partum mothers, at two major hospitals, in Jeddah city. The case group (47 women) is defined as those mothers who delivered an infant weighing <2500g and born at term (i.e. > 37 weeks of gestation), while the control group (58 mothers) were defined as women who delivered at term infants weighing ≥2500g. Data on previous and current known risk factors and dental care services were obtained from the patients' medical records and interviews. Maternal anthropometric data and DMFT scores were taken. Results: The selected case and control groups were relatively homogenous, based on their demographic, social and anthropometric data. However, there were significant differences between the groups in the distribution of some variables which could be associated with LBW in the study population. These include decrease in the gestational age; parity; previous delivery of LBW as well as maternal hypertension and anemia. Although the mothers in both groups had high unmet dental care needs, neither the DMFT scores nor the utilization of different dental treatments and radiographs were found to have a possible role in LBW; (P-value >0.05). Conclusion: The data of the present study showed no association between maternal dental health or dental care with LBW due to intrauterine growth retardation.
