Meta models are the core of enterprise architecture, but still few methods are available for the creation of meta models tailored for specific purposes. This paper presents two approaches, one focusing on the stakeholders’ information demand of enterprise architecture and the other driven by causal analysis of enterprise system properties. The two approaches are compared and a combined best-of-...

The proposed research integrates theories of demand-driven innovation and market value creation to explain (i) the role of demand in driving innovation in information security and (ii) the role of innovation in projecting firm performance thus determining firm market value. Time series and event study analyses are applied to show that malicious attacks, primarily those that exploit software vul...

Mobile ad hoc networking (MANET) is a growing technology that can support the operation of adaptive wireless networks. With the increased demand rate of wireless applications it is useful to have more adaptive and selforganizing technologies that adapt to changes within a network region. In this paper we initially present a brief listing of table driven ad hoc routing protocols and eventually a...

Characterization and evaluation of a biological submerged filter was carried out on a full-scale pilot plant performing removal of biochemical oxygen demand (BOD) and total nitrogen (TN) from pre-treated urban wastewater. The average influent values of BOD5, chemical oxygen demand (COD) and TN were 370, 1,015 and 60 mg/L, respectively. The pilot plant produced good discharge quality during stea...

aims: several methods have been used for textile wastewater treatment. the aim of this study was to evaluate the efficiency of rosa damascena watering waste ash for cod and color removal from textile wastewater.  materials & methods: rose watering waste was gathered from one of the kashan processing plants. the raw wastewater sample was taken from one of the textile industries in kashan country...

Objectives: OpenMusic (OM) is a domain-specific visual programming language designed for computeraided music composition. This language based on Common Lisp allows composers to develop functional processes generating or transforming musical data, and to execute them locally by demand-driven evaluations. As most historical computer-aided composition environments, OM relies on a transformational ...

Ray tracing is a powerful technique to generate realistic images of 3D scenes. However, the rendering of complex scenes under advanced lighting circumstances may easily exceed the processing and memory capabilities of a single workstation. Distributed processing offers a solution if the algorithm can be parallelised in an efficient way. In this paper a hybrid scheduling approach is presented th...

BACKGROUND At the turn of the 90s, studies showed that health research contributed little to health and development in low- and middle-income countries because it was oriented towards international priorities and dominated by researchers from the North. A new approach to North-South collaboration was required that would support demand-driven and locally led research in the South. The aim of thi...

Theories of ‘growth models’ explain capitalist diversity by reference to shifting drivers aggregate demand in different national economies. This article expands the growth models framework beyond its conventional focus on debt-driven and export-driven demand, through an ideational analysis Thatcher’s vision a property-owning democracy, Blair’s knowledge-driven agenda. Drawing policymakers’ stat...
