Simulation of the internal ballistics of a liquid propellant engine start system in comparison with experimental verification

Karimi, H. (author), Taheri, E.E. (author)

There are several methods for starting a complex mechanical system, for example a liquid propellant engine. One of common methods is the use of solid propellant gas generator that is named solid propellant starter. In this method, a solid propellant motor is used for gas generating and leading it towards power generation turbine. The turbine as...

Water Accounting Plus (WA+) – a water accounting procedure for complex river basins based on satellite measurements

Karimi, P. (author), Bastiaanssen, W.G.M. (author), Molden, D. (author)

Coping with water scarcity and growing competition for water among different sectors requires proper water management strategies and decision processes. A pre-requisite is a clear understanding of the basin hydrological processes, manageable and unmanageable water flows, the interaction with land use and opportunities to mitigate the negative...

Basin-wide water accounting based on remote sensing data: An application for the Indus Basin

Karimi, P. (author), Bastiaanssen, W.G.M. (author), Molden, D. (author), Cheema, M.J.M. (author)

The paper demonstrates the application of a new water accounting plus (WA+) framework to produce information on depletion of water resources, storage change, and land and water productivity in the Indus basin. It shows how satellite-derived estimates of land use, rainfall, evaporation (E), transpiration (T), interception (I) and biomass...

Spatial evapotranspiration, rainfall and land use data in water accounting. Part 1: Review of the accuracy of the remote sensing data

Karimi, P. (author), Bastiaanssen, W.G.M. (author)

The scarcity of water encourages scientists to develop new analytical tools to enhance water resource management. Water accounting and distributed hydrological models are examples of such tools. Water accounting needs accurate input data for adequate descriptions of water distribution and water depletion in river basins. Ground-based...

Water Accounting Plus (WAC) is a framework that summarizes complex hydrological processes and water management issues in river basins. The framework is designed to use satellite-based measurements of land and water variables and processes as input data. A general concern associated with the use of satellite measurements is their accuracy. This...

From global goals to local gains—a framework for crop water productivity

Blatchford, Megan Leigh (author), Karimi, Poolad (author), Bastiaanssen, W.G.M. (author), Nouri, Hamideh (author)

Crop water productivity (CWP) has become a recognised indicator in assessing the state of Sustainable Development Goals (SDG) 6.4—to substantially increase water use efficiency. This indicator, while useful at a global scale, is not comprehensive at a local scale. To fill this gap, this research proposes a CWP framework, that takes advantage...

Multi-twist polarization ribbon topologies in highly-confined optical fields

Electromagnetic plane waves, solutions to Maxwell's equations, are said to be 'transverse' in vacuum. Namely, the waves' oscillatory electric and magnetic fields are confined within a plane transverse to the waves' propagation direction. Under tight-focusing conditions however, the field can exhibit longitudinal electric or magnetic...

The accurate operation of a Food Supply Chain (FSC) is a critical issue as it directly interfaces with health and safety matters. This study addresses coordination and conflict management in a three-level FSC that embraces a new inventory type known as growing items like poultry and livestock. The chain involves a rearing farm as the supplier...

Long-term drought monitoring of the Zayandehrud River basin (central Iran) using hydroclimatological models and satellite observations

Babadi, Masoud (author), Iran Pour, Siavash (author), Roscher, Ribana (author), Amiri Simkooei, A. (author), Karimi, Hamed (author)

Drought is one of the most complex and threatening disasters, defined as a period of drier-than-normal conditions which results in water-related problems. In addition to climate variation, human activities can cause or intensify drought through groundwater overextraction, unsupervised expansion of agricultural lands, etc. One prime example of...
