Long;-range Planning for the Deep Space Network
نویسنده
چکیده
Conduct of space exploration is undergoing a significant transformatiion. Initial reconnaissance missions are giving way to long duration observations with data-intensive insfruments, in situ investigations and complex operations. To keep pace, a transformation in the Deep Space Network is in order. Downlink performance must increase by 1 to 2 orders of magnitude over the next decade and by a similar amount in uplink over the next 20 years. Comparable improvements in navigation precision will be required. Network topology will encompass a diversity of sites, including some owned by non-NASA agencies, others in Earth orbit, and still others deployed as local planetary infrastructure, particularly at Mars. Point-topoint links between nodes will evolve toward networked connectivity among nodes. Provision of services will move toward greater simplicity for the user backed by highly reliable systems. Finally, new types of high-level information services, enabled by high-capacity connectivity, will be developed so as to enable and enhance the next wave of space exploration.

The Neural Network Modeling Approach for Long Range Expansion Policy of Power Plant Ccenters
Traditionally, Electrical power plant capacities are determined after specific plant locations have been selected. In this paper an expansion policy of power plant centers involving the choice of regions that must be allocated to power plant centers and power plant centers capacities over a specified planning horizon (years) is tackled. The problem is performed as a mixed integerprogramming mod...
متن کاملDeep space missions and the issue of overcoming the problem of space radiation
As a member of the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), Iran has a long-term space exploration program. Space radiation is one of the challenges facing humans when they go outside Earth's protective atmosphere and magnetic field. Space is an environment that the cardinal principles of radiation protection i.e. time, distance and shielding cannot be effectively ...
متن کاملShort term electric load prediction based on deep neural network and wavelet transform and input selection
Electricity demand forecasting is one of the most important factors in the planning, design, and operation of competitive electrical systems. However, most of the load forecasting methods are not accurate. Therefore, in order to increase the accuracy of the short-term electrical load forecast, this paper proposes a hybrid method for predicting electric load based on a deep neural network with a...

Accurate flood forecasting is a vital need to reduce its risks. Due to the complicated structure of flood and river flow, it is somehow difficult to solve this problem. Artificial neural networks, such as frequent neural networks, offer good performance in time series data. In recent years, the use of Long Short Term Memory networks hase attracted much attention due to the faults of frequent ne...
متن کاملDetecting Overlapping Communities in Social Networks using Deep Learning
In network analysis, a community is typically considered of as a group of nodes with a great density of edges among themselves and a low density of edges relative to other network parts. Detecting a community structure is important in any network analysis task, especially for revealing patterns between specified nodes. There is a variety of approaches presented in the literature for overlapping...
