A deliberative model for self-adaptation middleware using architectural dependency
A crucial prerequisite to externalized adaptation is an understanding of how components are interconnected, or more particularly how and why they depend on one another. Such dependencies can be used to provide an architectural model, which provides a reference point for externalized adaptation. In this paper, it is described how dependencies are used as a basis to systems' self-understanding and subsequent architectural reconfigurations. The approach is based on the combination of: instrumentation services, a dependency meta-model and a system controller. In particular, the latter uses self-healing repair rules (or conflict resolution strategies), based on extensible beliefs, desires and intention (EBDI) model, to reflect reconfiguration changes back to a target application under examination
Parsing Thai Social Data: A New Challenge for Thai NLP
Dependency parsing (DP) is a task that analyzes text for syntactic structure
and relationship between words. DP is widely used to improve natural language
processing (NLP) applications in many languages such as English. Previous works
on DP are generally applicable to formally written languages. However, they do
not apply to informal languages such as the ones used in social networks.
Therefore, DP has to be researched and explored with such social network data.
In this paper, we explore and identify a DP model that is suitable for Thai
social network data. After that, we will identify the appropriate linguistic
unit as an input. The result showed that, the transition based model called,

The i* framework for goal-oriented modeling
The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-39417-6i* is a widespread framework in the software engineering field that supports goal-oriented modeling of socio-technical systems and organizations. At its heart lies a language offering concepts such as actor, dependency, goal and decomposition. i* models resemble a network of interconnected, autonomous, collaborative and dependable strategic actors. Around this language, several analysis techniques have emerged, e.g. goal satisfaction analysis and metrics computation. In this work, we present a consolidated version of the i* language based on the most
adopted versions of the language. We define the main constructs of the language and we articulate them in the form of a metamodel. Then, we implement this version and a concrete technique, goal satisfaction analys is based on goal propagation, using ADOxx. Throughout the chapter, we used an example based on open source software adoption to illustrate the concepts and test the implementation.Peer ReviewedPostprint (author's final draft
Anticipating Daily Intention using On-Wrist Motion Triggered Sensing
Anticipating human intention by observing one's actions has many
applications. For instance, picking up a cellphone, then a charger (actions)
implies that one wants to charge the cellphone (intention). By anticipating the
intention, an intelligent system can guide the user to the closest power
outlet. We propose an on-wrist motion triggered sensing system for anticipating
daily intentions, where the on-wrist sensors help us to persistently observe
one's actions. The core of the system is a novel Recurrent Neural Network (RNN)
and Policy Network (PN), where the RNN encodes visual and motion observation to
anticipate intention, and the PN parsimoniously triggers the process of visual
observation to reduce computation requirement. We jointly trained the whole
network using policy gradient and cross-entropy loss. To evaluate, we collect
the first daily "intention" dataset consisting of 2379 videos with 34
intentions and 164 unique action sequences. Our method achieves 92.68%, 90.85%,
97.56% accuracy on three users while processing only 29% of the visual
observation on average
A goal-oriented requirements modelling language for enterprise architecture
Methods for enterprise architecture, such as TOGAF, acknowledge the importance of requirements engineering in the development of enterprise architectures. Modelling support is needed to specify, document, communicate and reason about goals and requirements. Current modelling techniques for enterprise architecture focus on the products, services, processes and applications of an enterprise. In addition, techniques may be provided to describe structured requirements lists and use cases. Little support is available however for modelling the underlying motivation of enterprise architectures in terms of stakeholder concerns and the high-level goals that address these concerns. This paper describes a language that supports the modelling of this motivation. The definition of the language is based on existing work on high-level goal and requirements modelling and is aligned with an existing standard for enterprise modelling: the ArchiMate language. Furthermore, the paper illustrates how enterprise architecture can benefit from analysis techniques in the requirements domain
Deceiving, Fraudulent, and Seductive: The Discourses of Money in US Novels of the Early Republic
This thesis focuses on the importance of money and the representations of its various physical manifestations (such as coin, paper money) in American fiction of the 1790s. My project traces the transition from the colonies\u27 financial dependency on Britain to their independency, relating to the monetary union created after the passage of the constitution. I argue that this shift from financial dependency to independency influences books such as Charlotte Temple by Susanna Rowson, Kelroy by Rebecca Rush, Ormond or the Secret Witness and Arthur Mervyn by Charles Brockden Brown. My project highlights, on the one hand, the importance of such a transition as it demonstrated a form of independence from the Crown; yet, on the other hand, this independence created issues among the colonists particularly as periodic financial crises or shortages of circulating money led to great uncertainty. These uncertainties emerge in the fiction of the day, especially in anxiety over the monetary union and paper currency. The transition toward a monetary union created social and commercial problems for merchants, businessmen, and families. Within this system, money seemingly becomes a traumatic object that deceives, seduces, and betrays people. Characters in the novels perceive money as treacherous, tricking people into believing in its arbitrary, imaginary, and socially constructed power. Money is anthropomorphized insofar as it seems to have intentions. Building on thing theory, I consider paper money a hyperobject, imbued with an apparent agency. In my thesis, I explore the implications of this widespread reaction to this strange power of paper currency. In this regard, paper money\u27s hyperobjectivity is revealed by examining the notion of commodification, closely exploring instantaneous changes that occur in the novels in relationship to economic changes, and money\u27s ephemerality
