Developing a Case-based Emergency Response System with Adaptive Case Management

Published in Journal of Homeland Security and Emergency Management

The emergency responses required during large-scale crises or disasters are extremely knowledge-intensive processes and are usually characterized by a high degree of unpredictability and unrepeatability. An emergency response is mission- and time-critical, unstructured, very dynamic, and it is very difficult to predefine or even to anticipate all p...

Assessment of the GOES-16 Clear Sky Mask Product over the Contiguous USA Using CALIPSO Retrievals

Cloud initialization is a challenge in numerical weather prediction. Probably the most relevant observations for this task come from geostationary satellites. These satellites provide the cloud mask with high spatio-temporal resolution and low latencies. The low latency is an attractive option for nowcasting systems such as the solar irradiance now...

A Novel Design and Optimization Approach for Low Noise Amplifiers (LNA) Based on MOST Scattering Parameters and the gm/I...

This work presents a new design methodology for radio frequency (RF) integrated circuits based on a unified analysis of the scattering parameters of the circuit and the gm/ID ratio of the involved transistors. Since the scattering parameters of the circuits are parameterized by means of the physical characteristics of transistors, designers can opt...

Physicochemical Properties of African Catfish Mucus and Its Effect on the Stability of Soya Milk Emulsions

Mucus, a waste product produced when African catfish undergoes stress, has lubricating effects and could be a potential emulsifier. Emulsions are thermodynamically unstable / researchers have documented synthetic bio-polymers as emulsifiers, but its sustainability is in question. This research aims to establish some physicochemical properties of Af...

Analysing decentralised natural resource governance: proposition for a “politicised” institutional analysis and developm...

Published in Policy Sciences

There has often been a gap between policy intentions and outcomes in the field of natural resource governance. Analysing the factors for these discrepancies requires multi-level approaches that relate policy decisions formulated at the national and international level with the decisions of local resource users. A key asset of the Institutional Anal...

High Resolution Satellite Images for Instantaneous Shoreline Extraction Using New Enhancement Algorithms

Knowledge of a territory is an essential element in any future planning action and in appropriate territorial and environmental requalification action planning. The current large-scale availability of satellite data, thanks to very high resolution images, provides professional users in the environmental, urban planning, engineering, and territorial...

A Color Image Encryption Technique Based on Bit-Level Permutation and Alternate Logistic Maps

Published in Journal of Intelligent Systems

The paper presents an approach to encrypt the color images using bit-level permutation and alternate logistic map. The proposed method initially segregates the color image into red, green, and blue channels, transposes the segregated channels from the pixel-plane to bit-plane, and scrambles the bit-plane matrix using Arnold cat map (ACM). Finally, ...
