The term spatial data signifies all geometric objects of different dimensions and the relations that could bind these objects together. Spatial data is, in general, divided into two parts: crisp spatial data and vague spatial data. Crisp spatial data has determinate coordinates and boundaries, whereas vague spatial data has indeterminate ones. The demand for spatial data support in database management systems is growing every day, yet not all commercial products provide spatial data support natively, and those that do merely provide it partially. Since database management systems are at the heart ...

The internet is once again suffering from its own success. Since 1995, there has been a massive increase in demand for internet services, resulting in an exponential growth of the Internet. We have entered now an era where the users of the Internet are unable to obtain the bandwidth needed to support their applications, and they are experiencing high packet loss. Packet loss problem arises whenever the number of packets arriving at a given router is much higher than its buffering space. The main goal of this thesis is to find adaptive schemes capable of optimizing the communication network ...

This research aims to validate the viability of implementing NFT mechanics in a video game. It discusses the blockchain technology’s limitations, as well as the many restrictions that NFT forces on game developers. Be it their immutable nature, their high minting cost, or their incapacity of holding big data. It also highlights the restrictions that prevent the interoperability of game assets, and finally, the ludicrous Play-to-earn business model. Two games are also developed, Crypto Forgers and Crypto Run, to further validate the findings presented by this research. While these two games are ...

With the advancement in computing and wireless technologies, the world has witnessed a growing number of connected devices to the Internet at an unpretending rate. Fog computing emerges as an alternative solution to reduce the burden of Data Centers in traditional Cloud Computing and to support geographically distributed, latency sensitive, and QoS-aware IoT appliations. Fog Computing suggests, that the intelligence should move from the data centers to the edge of network. The main objective of this thesis is to determine the significance and feasibility of implementing a broker node between ...

Delay-Tolerant Networks (DTNs) are a type of emerging networks characterized by very long delay paths, frequent network partitions and high loss rates. The nodes are sparsely deployed and intermittently connected. The presenting network is used in a variety of environments including military, disaster situations and for long distance communications. Although it is used in critical sectors, the communication support lacks the high end technology usually found in important networks. The nodes participating in this network do not have stable end-to-end connections. They can communicate to each other ...

With the rise of the Internet, recommender systems are becoming a used solution to solve the information overload problem. These systems are like any other system, subject to noise: malicious noise that is caused by attacks and natural noise that is due to the human error. Many detection algorithms solve the noise problem. However, since natural noise and serendipity overlap in their definition, removing noise results in removing serendipity. Serendipity that is the happy surprise of finding something relevant unexpectedly is important for the issue of over personalization caused by the recommender ...
