This paper investigates the stability properties of second-order systems. \dot{x} = f(x) , where f(x) contains either quadratic terms-system (1)-or linear and quadratic terms-system (2)-in x . The principal contributions are summarized in two theorems which give necessary, and sufficient conditions for stability and asymptotic stability in the large of systems (1) and (2), respectively.

The half-space problem of rarefied gas flow (the Kramers problem) is considered for the linearized Boltzmann equation and arbitrary gas-surface interaction. Accurate numerical results for the velocity slip coefficient and velocity defect are obtained for the rigid sphere interaction and Maxwellian boundary condition.
Over the past several decades, the Department of Defense (DoD) has developed an expansive network of systems that must interoperate on the battlefield to deliver value to the users. However, it is difficult to manage ...

A control problem involving a mechanical system with generalized coordinates q ∈ R m is considered. The error in tracking a desired input y d ∈ R p is e = E (q,y d )∈ R m . If E satisfies simple conditions, it leads to a nonlinear control law that assures e (t)→0 as t →∞. The law is robust in that small changes in it do not produce large steady-state errors or loss of stability. In this theory a unified framework is presented for treating a number of problems in the control of mechanical manipulators.

The process of information systems (IS) planning in an organization occurs when there is a set of IS projects that require implementation, generally within certain time frames and budgetary constraints. We propose a method for determining an optimal order of project implementation. The proposed method utilizes the cost-benefit graph, which considers the expected cost and benefit of each of the projects comprising the set, as well as the weight (importance) of the cost and benefit factors to the decision-makers. The method allows us to analyze the sensitivity of a preferred implementation order to changes in cost and benefits, and the importance of these factors.

This article outlines a unified Communication Theory linking cyber-systemic, and cyber-semiotic perspectives. The objective is explaining communication as an emergent system from the interaction process between socio-ecological systems. The emergent communication system seen from a unified perspective is applied as a participative integral transformation process toward the harmonic relationship between human communities and their dynamic social and natural environment. It includes the description of an evolutionary communication process between social and environmental leaders of organizational networks under real conditions. It describes the evolutionary stages of the communication system between different social and environmental leaders who have been working in social organizational networks of Mexico in the last thirty years. The last stage of this emergent communication process among social organizational networks leaders began in 2009, is called: the Ecosystemic Dialogues, it is communication system with qualitative complexity and critical awareness. It is a social laboratory of change under real conditions, through a participative action-research cybernetic process, for a harmonic and sustainable relationship between human and natural systems, through a complex communication dynamic. It is a process toward the sustainable systemic health of the planet.

A three-phase information system analysis and design methodology is being used to continuously improve enterprise information systems as part of a six-step annual business improvement process. Following senior management's strategic decisions on next year's product and/or service portfolio content, interacting financial, management, engineering, and quality improvement processes are analyzed to determine their output product and/or service quality and timeliness. Concurrently, facilities, equipment, and personnel resources required for individual processes are inspected for possible immediate or future improvement. Throughout these analyses minimum essential information (MEI) requirements are derived using the Object Transformation Process Model (OTPM). Individual OTPM models are linked to help identify all pertinent data sources, information destinations, and timing requirements. The linked OTPM models are mapped onto an Embedded Computer System (ECS) model that defines a physical architecture for improving telecommunication paths between all humans, machines and embedded computers that are component parts of the integrated processes. This approach yields comprehensive information system logical and physical architectural models that can recursively guide high-leverage enterprise-wide improvement projects over succeeding fiscal years.
