This thesis attempts to come closer at resolving three highly contested issues involving investor sentiment. First are the theoretical issues of defining and modeling sentiment in an intuitive and parsimonious way. To date, there has been no commonly accepted definition, let alone theory, of investor sentiment since the term may be used in different ways depending on the context. In this thesis...

high resolution range profile (hrrp) is being known as one of the most powerful tools for radar target recognition. the main problem with range profile for radar target recognition is its sensitivity to aspect angle. to overcome this problem, consecutive samples of hrrp (or feature vectors extracted from them)were assumed to be identically independently distributed (iid) in small frames of aspe...

The most common approach to network development in the modern organization remains an undocumented, ad hoc method of deploying available technology rapidly to fit within a given cost structure. Current methods largely ignore the importance of integrating the networking strategy of a firm with the overall information systems architecture of the enterprise. To address this problem, a new approach...

The Business Process Execution Language for Web Service (BPEL4WS) is a XML based standard for defining how to integrate Web Services to implement business processes. A BPEL4WS process is defined in terms of its interactions with partner. A partner may provide services to the process and also may require services from the process, or participate in two-way interaction with the process. This repo...

This paper presents a methodological approach for the engineering of Multi-Agent Systems using feedback loops as a first class concept in order to identify organizations. Feedback loops are a way for modeling complex systems that expose emergent behavior by means of a cause-effect loop between two levels called micro and macro levels of the system. The proposed approach principles consist in de...

Enterprise Architecture (EA) projects require analyzing and designing across the whole enterprise and its environment. Enterprise architects, therefore, frequently develop enterprise models that span from the markets in which the organization operates down to the implementation of the IT systems that support its operations. In this paper, we present SEAM for EA: a method for defining an enterpr...

An objective function often is only a rough approximation of the actual goals of the organization and its stakeholders. Consequently, an optimal solution may be no more interesting than other solutions that provide good values. Beyond this, a set of “good” solutions whose members have diverse characteristics can be significantly more valuable for practical analysis and planning than any single,...
