An Open System Environment for Real-Time Applications
… the design and the implementation of the open system as an extension to a general purpose thread-based operating system. The extension includes three components: (1) a two-level kernel scheduler and an admission control mechanism, (2) a set of system service providers, and (3) a set of …

How open should an open system be? : essays on mobile computing
"Systems" goods-such as computers, telecom networks, and automobiles-are made up of multiple components. This dissertation comprises three essays that study the decisions of system innovators in mobile computing to "open" development of their systems to outside suppliers and the implications of …

Resource scheduling and design of real-time Cyber-Physical Systems in the open system environment
… the problem of resource provisioning and system designs for real-time Cyber-Physical Systems (CPS) in an open system environment. In an open system environment, there does not exist a global resource scheduler that has complete knowledge of the real-time performance requirements of each …

Mineral equilibria constraints on open-system melting and consequences of melt loss in metabasic rocks
Metabasic rocks constitute a significant proportion of the rock types found within orogenic metamorphic terranes, and the high temperature (T), suprasolidus behaviour of these lithologies provide an important contribution to the process of internal differentiation in the continental crust. The …

Effects of extended cycles of open system freezing and thawing on a clay-lime mixture
… this study was to evaluate effects of long term open system freezing and thawing on unconfined compressive strength of a lime-clay mixture and determine if length of curing has appreciable effect on strength and durability of the mixture. Soil specimens were made by compacting the soil slightly …

A Distributed Open Environment for Real-Time Applications
… applications that may run concurrently in the system. Reconfiguring such a system is expensive and often done offline. This fact has motivated the design of open system architecture. Open system is a hierarchical reservation-based framework that provides temporal guarantee and isolation to …

Studies related to the artificial spawning and culture of the Abalone, Haliotis midae linne, 1785
… various aspects of abalone biology and seawater system design. A comparative evaluation of a closed and open seawater system for an H. midae hatchery was performed. Monthly seawater temperatures and nitrite levels were higher in the closed system. The salinity of the closed system seawater varied …

Modeling the Non-equilibrium Phenomenon of Diffusion in Closed and Open Systems at an Atomistic Level Using Steepest-Entropy-Ascent Quantum Thermodynamics
… a non-equilibrium-based model for an isolated system in which He3 diffuses in He4. The model developed is able to predict the non-equilibrium and equilibrium characteristics of diffusion as well as capture the differences in behavior of fermions (He3) and bosons (He4). The SEAQT framework is …

Policy design and complexity: community relations policy in Northern Ireland since The Agreement
… and the domain is understood as an organic open system. In this study a co-evolutionary, flexible process between policy makers and the complicated open system they seek to influence is explored through the stakeholders’ role in the emergence of community relations policy. Engaged citizens …

Experimental diagenesis of lime mud
… limestones (micrites) were produced by closed-system (70-200$\sp\circ$C/1-15.6 bars/1-486 days) and open-system (90-95$\sp\circ$C/1 bar/63-311 days; 10-200 mL/day) hydrothermal experiments on a variety of lime muds ($<$25 $\mu$m size fraction), including natural lime muds, laboratory …

The relationship between perceived organizational climate and hotel expatriate adjustment
… of perceived organizational climate of the open system model were derived from the literature: commitment to learning, shared vision, open-mindedness, and innovativeness. To measure expatriate adjustment, three facets of adjustment [(i) general, (ii) interactional, and (iii) work …

Quality of Service and Optimization in Data Integration Systems
… the construction of a global data integrations system. Similar to distributed databases this system allows declarative queries in order to express user-specific information needs. Scalability towards global data integration systems and openness were major design goals for the architecture and …

A central Texas drying event identified at the Younger Dryas-early Holocene transition using coupled speleothem 𝛿¹³C-¹⁴C analysis
… partial dissolution in a water-saturated closed system to dissolution in an open system, where carbon from limestone has no measurable effect on dissolved inorganic carbon ¹⁴C activities. A negative shift in 𝛿¹³C values of 2.8‰ coincident with a decrease in DCP from 7.5 to 0% occurs in McN-1 at …

Implementing Motivational and Participative Management Strategies to Curb Organisational Inequity
… to understand the motivational process as an open system from a business perspective because psychoanalysis and behaviorism dominated the developmental process of most of the motivation theories. In addition, the extant literature provides a great deal of information about the explicit …

Platinum-group element mineralisation in the Shetland ophiolite complex
… attributed to influxes of primitive magma during open system fractionation. The distribution of PGE and other chalcophiles show primary lithological associations, indicating a magmatic origin. Os-Ir-Ru concentrations occur in cbromitites, whereas Pt-PdRh concentrations occur in sulphide-bearing …
