The Multimedia Internet KEYing (MIKEY) specification describes a key management scheme for real-time applications. In this document, we note that the currently defined MIKEY modes are insufficient to address deployment scenarios built around a centralized key management service. Interest in such deployments is increasing. Therefore, a set of new MIKEY modes that work well in such scenarios are ...

Overloads (i.e., critical imbalances between traffic demand and capacity) are currently resolved in the European air transportation network by activating flow management regulations. Flights subject to regulations delayed on ground computer assisted slot allocation system, which uses a first-planned, first-served principle allocate delays. In last decades, many researchers have proposed alterna...

This study aimed at modeling scenarios of future land use and cover (LULC) change estimating ecosystem service (ES) values for the year 2051 compared to 2021 in Central Ethiopia. The LULC changes were simulated four scenarios, namely Business-as-Usual (BAU), Rapid Agricultural Expansion (RAE), Ecosystems Protection Development (EPAD) Landscape Restoration Conservation (LERC). based on anticipat...

Ecosystem modelling is increasingly used to explore ecosystem-level effects of changing environmental conditions and management actions. For coral reefs there has been increasing interest in recent decades in the use of ecosystem models for evaluating the effects of fishing and the efficacy of marine protected areas. However, ecosystem models that integrate physical forcings, biogeochemical and...

Poorly managed e-waste can lead to public health and environmental problems resulting from the leakage of toxic substances. Building upon integrated management (IEWM) concept, this study aims propose an sustainable strategy. It also suggests alternative processes for effective collection, treatment, disposal e-waste. In its first stage system dynamics modeling, employed approach comprising inte...
