A model for strategic communication management was developed in South Africa on the basis of the excellence study and relationship management theories. This normative, theoretical model has been applied as part of a project in non-profit organisations (NPOs), government institutions and small-to-medium sized companies. However, the operational reality of organisations’ communication practices has

This paper presents a novel polynomial constraint for homographies compatible with the general planar motion model. In this setting, compatible homographies have five degrees of freedom-instead of the general case of eight degrees of freedom-and, as a consequence, a minimal solver requires 2.5 point correspondences. The existing minimal solver, however, is computationally expensive, and we propose

Popular Abstract in Swedish Storbritannien beslutade sig 1968 för att lämna bakom sig sina koloniala intressen i Persiska gulfen senast 1971. Det brittiska beslutet ledde till att de arabiska gulfstaterna Kuwait, Bahrain, Saudiarabien, Qatar, Förenade Arabemiraten och Oman i sin tur började undersöka möjliga samarbetsformer för att möta en ny tids osäkerhet och hot. Ett stort problem efter det briWhen Britain decided, in 1968, to terminate its official colonial presence in the Persian (Arabian) Gulf as of 1971, this action prompted the Gulf Arab States (Kuwait, Bahrain, Saudi Arabia, Qatar, United Arab Emirates, and Oman) to start the search for a form of partnership that would bring them together to better cope with the insecurity and danger surrounding them and their regimes. A key probl

Control-Based Operating System Design describes the application of system- and control-theoretical methods to the design of computer operating system components. It argues that computer operating system components should not be first “designed" and then “endowed with control", but rather conceived from the outset as controllers, synthesised and assessed in the system-theoretical world of dynamic m

Background: Epigenetic factors regulate tissue-specific expression and X-chromosome inactivation. Previous studies have identified epigenetic differences between sexes in some human tissues. However, it is unclear whether epigenetic modifications contribute to sex-specific differences in insulin secretion and metabolism. Here, we investigate the impact of sex on the genome-wide DNA methylation pat

Ecosystem governance becomes gradually more relevant for a set of companies or actors characterized by symbiotic relations evolved on the top of a technological platform, i.e. a software ecosystem. In this study, we focus on the governance of a hardware-dependent software ecosystem. More specifically, we evaluate the governance model applied by Axis, a network video and surveillance camera produce

This thesis investigates the topic of joint positioning and radio channel estimation and prediction. Both positioning and radio channel estimation have a long history of research with many publications but the combination of the two has so far at large been left unexplored. The reason for studying this topic is twofold: improvement of positioning and improvement of radio channel prediction. Positi

Time synchronisation is crucial for distributed systems, and particularly for Wireless Sensor Networks (WSNs), where each node is executing concurrent operations to achieve a real-time objective. However, synchronisation is quite difficult to achieve in WSNs, due to the unpredictable deployment conditions and to physical effects like thermal stress, that cause drifts in the local node clocks. As a

In this paper, we consider robust stability analysis of large-scale sparsely interconnected uncertain systems. By modeling the interconnections among the subsystems with integral quadratic constraints, we show that robust stability analysis of such systems can be performed by solving a set of sparse linear matrix inequalities. We also show that a sparse formulation of the analysis problem is equiv

Stability of some decentralized traffic signal control policies for urban traffic networks is studied. It is proven that, whenever the arrival rates belong to a certain region -which is the largest where stability is possible- the resulting traffic network dynamics admit a globally asymptotically stable equilibrium. The results rely on the use of some entropy-like Lyapunov functions previously con

We are concerned with software that can self-adapt to satisfy certain reliability requirements, in spite of adverse changes affecting the environment in which it is embedded. Self-adapting software architectures are heavily based on dynamic binding. The bindings among components are dynamically set as the conditions that require a self-adaptation are discovered during the system's lifetime. By ado

This paper presents a suggested methodology based on virtual reality (VR) technology that enables people with cognitive disabilities to communicate their knowledge and experiences of public transport systems. The users interacted with the VR system by verbally describing their actions to the person controlling the VR system and/or pointing with a laser pointer while seated in front of three screen

Are places with a successful tourist industry also successful when it comes to attracting migrants? In the present paper this hypothesis is empirically tested on interregional migration in Sweden. The paper draws on recent interest in, and research on, the relationship between tourism and migration. This line of research could be seen as an extension of traditional quality of life studies on migra

Feature quantization is a crucial component for efficient large scale image retrieval and object recognition. By quantizing local features into visual words, one hopes that features that match each other obtain the same word ID. Then, similarities between images can be measured with respect to the corresponding histograms of visual words. Given the appearance variations of local features, traditio
