EBO focus on the effects of the operations rather than dealing with actions, targets, or even objectives. The literature on EBO has been growing day by day; however, there is still a need for modeling techniques and tools that provide more efficient and effective effects based assessment, planning and analysis in order to further develop the capabilities of the operations. In this context, this paper presents an introduction to EBO by focusing on its methodology, its challenges and also its applicability in different systems. Moreover, this paper illustrates the importance of modular system design in effects based planning stage. Modular design provides synchronization of the right actions and decisions, makes strategic aim consideration easier and provides efficiency in the cases where there are multiple strategic aims. The most important benefit of this research is its ability to facilitate the achievement of economy of national power for military EBO and economy of action sources for other systems. Approaches presented in this paper utilize clustering of effects and actions by using two neural network architectures; namely, Adaptive Resonance Theory (ART1) and Kohonen\u27s Self Organizing Maps (SOM). The applications of the approach are illustrated with a defense industry related example in the development of a modular EBO system. Overall, the modular architecting approach has been successfully applied to the example and it is concluded that although ART1 is a good architecture for clustering, Kohonen\u27s SOM is more helpful in defining modules for effects and actions in EBO. Finally, it is understood that further research of this paper would contribute to the modular design of EBO by applying other neural network architectures with larger input data sets

We have been designing and acting as designers (sometimes unconsciously) throughout our lives. Design begins with the acknowledgment of needs and dissatisfaction with the current state of affairs and realization that some action must take place in order to correct the problem. When a small child moves a stool to an appropriate location so that she can use it to get to her toy, she has acted as a designer — of a rudimentary design — by positioning the stool so that she can satisfy her need of playing with the toy.

Despite the pressing demands for groundwater resources, groundwater withdrawals are not actively monitored in most regions. Thus, reliable methods are required to estimate withdrawals at local scales suitable for implementing sustainable groundwater management practices. Here, we combine publicly available remote sensing datasets into a deep learning framework for estimating groundwater withdrawals at high resolution (5 km) over the states of Arizona and Kansas in the USA. We compare ensemble machine learning and deep learning algorithms using groundwater pumping data from 2002–2019. Our research shows promising results in sub-humid and semi-arid (Kansas) and arid (Arizona) regions, which demonstrates the robustness and extensibility of this integrated approach. The success of this method indicates that we can effectively and accurately estimate local-scale groundwater withdrawals under different climatic conditions and aquifer properties.

While an internet of vehicles architecture must be optimized for its key performance metrics, because of the technological volatility, additional objectives measuring the sensitivity of the key performance metrics to technological change should also be included. This would minimize the impact of evolving technologies although it would also effectively double the number of objectives. A large number of objectives creates a significant difficulty for optimization due to Pareto breakdown where a large percentage of the solution space is non-dominated. An approach is developed that casts this as a cyber-physical systems architecting problem using a meta-architecture that represents the problem in terms of systems and interfaces. The systems are formally characterized in manner allowing the objectives to be calculated given an architecture which is a particular instance of the meta-architecture. The meta-architecture is structured as a chromosome to allow the use of a many-objective evolutionary algorithm to optimize the architecture despite the large number of objectives present. An evolutionary algorithm was chosen because it does not require a continuous solution space and can readily enforce constraints on solutions. A guide to problem formulation and models of representative objectives and feasibility constraints are provided to demonstrate this approach.

As systems development problems and their solutions become more complex, it is becoming increasingly harder for organizations to meet the current competitive environment. The main problem is that when modifying or developing complex systems, it is hard to determine the solution space and variables that might impact the system. While much progress has been made in the development of requirements elicitation and documentation there is still more to be done

In this new world, there is less emphasis on isolated devices and greater emphasis on information exchange. This shift is making knowledge management and application integration key issues in computer technology. In order to stay competitive, a company is held hostage by how it understands, maintains and accesses its data. Data comes from many sources, containing a variety of types and formats. One possible way to tackle this complex data problem is to implement an ontology, a unifying framework that facilitates communication through a shared understanding and vocabulary of a system. It enables communication between systems that are independent of system technologies, information architectures and application domain. This paper describes the importance of ontologies in knowledge management and provides the basis on how to architect such an ontological system

It also provides an example of how network centric solutions can be used to do a kill Chain and its advantages over platform centric scenarios. NCW faces a lot of challenges to System Engineers interoperability, increased complexity, fault tolerance, distributed computing are all needed to be understood to make NCW a reality. The nature of network centric makes us focus also on wireless networks and how they can be used, its advantages, protocols, and later on two frameworks implemented by Sun, Jini an Jxta. Each has its own set of protocols, procedures and ideology, and both are being used to create very reliable networks with changing topology

The characteristics of one particular VGT, the Double-Octahedral Parallel Module (DOPM), allow the truss structure to move and compress with degrees of freedom, while maintaining a hollow geometry and low weight. This thesis describes a new motion method for the DOPM-VGT, called Follow the Leader, in which many serially-connected VGT modules move single file in a path to reach a goal trajectory. --Abstract, page iii

This paper only reports research using a multi-layer feed forward architecture with one input variable. Target variables are the cumulative distribution of the input data and the constant one. Although learning is supervised, values are derived only from input data itself and the state of the network
