This paper presents a proposal for a suitable and viable combination of a face recognition system and a watermarking system, namely a PCA—DCT combination, as a new watermarked face recognition scheme that will ensure the authenticity of the data being transmitted in the face recognition system, which will then increase its level of security. The emphasis is on recognizing and rejecting stolen biometric...
This paper presents a proposal for a suitable and viable combination of a face recognition system and a watermarking system, with a watermarking technique that will ensure the authenticity of the data being transmitted in the face recognition system, which will then enhance its level of security. The proposed combination is a PCA—DCT system.
This paper proposes a combination of network frequencies as the supporting medium for communication within a small Search and Rescue (SAR) team to ensure stable communication, and thus command and control, in particular in a forest environment. The proposal is to implement a combination of 869 MHz and 2.4 GHz, which will support the use of smart phones for the SAR team members for audio/oral, visual...
Search and Rescue (SAR) is an operation conducted to find and return to safety the survivors of an emergency incident, where the search may have to be conducted in difficult areas such as in mountains, deserts, forests or at sea. A SAR operation typically requires a search grid for the identified search area, and a search pattern to conduct a search that covers the grid, together forming a search...
The procedure for counting colonies is often performed manually and the process is lengthy and tedious. For that reason, several methods that rely on digital images for automatically counting cells and bacteria colonies have been proposed. Fully automated and high throughput hardware imaging instruments are also available, but such machines are extremely costly. In this paper, we introduce a mobile...
Search and Rescue (SAR) is an operation conducted to find and return to safety the survivors of an emergency incident, where the search may have to be conducted in difficult areas such as in mountains, deserts, forests or at sea. Maritime SAR operations normally involve a large number of vessels and possibly helicopters as well, but this has been found not to be effective enough. This paper looks...
In studying traffic congestions at toll plazas, a basic model for traffic systems is introduced, which will hopefully contribute towards a longer term solution with the means for explaining and predicting congestions. It is targeted that this can then be followed by a more specific operations research approach, based on a simulation and queuing theory model, with a study on different arrival patterns,...
