Markov Model for Tweets Geographic Distribution Characterization

2015

Abstract In this paper we will continue our researches regarding e-Business and e-Government modeling on Social Media presented in (Stoica, Pitic, & Mihaescu, 2013). Among message and user parameters we add a new parameter used to describe the geographical dispersion of Twitter messages. This new parameter will characterize the way one set of messages will spread in Social Graph from the physical word point of view. The first model, presented as “A Novel Model for E-Business and E-Government Processes on Social”, will be extended with the geographical parameter PG. We will define and we will describe the Markov Model used to organize the messages gathered from social media. The main idea of…

Using Search Algorithms for Modeling Economic Processes

2013

Abstract Economic issues are placed in formal practice, when is desired a modelling of the economic process, a manufacturing process, a device, etc. Each share of that economic process is denoted by a, b, c, d, these actions with defined time periods and action pairs are formed strings of the form, ab * cab * bc ., ab, bb, bc. so for them there are no other restrictions. If the graph is viewed as a system image, nodes representing components, then an immediate interpretation of an arc (xi, xj) are the component xi that is said to directly influence component xj. If nodes have the significance of possible states of a system when a spring (xi.xj) means that, the system can jump from state xi …

Specialized Applications Used in the Mobile Application Security Implementation Process

2020

In the paper, authors aim to determine the extent to which open source applications can replace specialized security applications for mobile applications. In this respect, open source components are selected at which level the implemented security features are identified, based on which a completeness-determining indicator is calculated. The value of this indicator is then compared to the value obtained for the .NET CF3 framework, with a hierarchy of the components being treated according to this indicator. Based on the same selected components or components derived from them, to which other components have been added, the issue of ensuring their quality is dealt with by calculating the com…

The Audit of SME’s Informatics Systems

2018

Basically, ERP implies a policy that reflects what it means to think and act for the purpose of economic processes and is therefore considered a strategic management solution. The new business model with process-focused operations increases productivity and meets the economic performance standards. The economic operational stages must be integrated in order to trigger workflows, to control the flow of information, and to create connections between the organization, suppliers, and customers. All this requires organizational changes, technological updates, and, eventually, a new identity for the organization itself. The present paper proposes a specific approach to the procedures needed to pe…
