The dynamics of social networks, namely the way connections are created and strengthened between individuals, is a very complicated process with many factors interfering in the emergence and evolution of social ties. Current research tries to better explain the high complexity of such network structures, by proposing corresponding algorithmic models for the evolution of topologies and influence propagation. Nevertheless, state of the art models have multiple limitations, as they typically make simplifying assumptions about opinion interaction mechanisms with fixed thresholds, non-dynamic topologies, or pervasive opinion sources.
This project comes to push the boundaries of scientific understanding forward, on several levels, by placing novel and existing pieces of the puzzle together, in terms of better predicting the spread of opinion over large social temporal networks. The main objectives of this project are:
- To define an original temporal agent-based interaction model (with a dynamic time-aware threshold);
- To explore and define, through mathematical modeling and computer simulation, novel trade-off strategies for improving opinion diffusion coverage, while maintaining a minimal cost of operation for engaged spreader agents;
- To improve the prediction accuracy of opinion distribution by integrating the temporal attenuation paradigm, with direct applicability in electoral poll forecasting;
- To combine the obtained interaction model, with diffusion strategies, and temporal poll prediction into a simulator application for defining a robust opinion poll prediction framework.
The motivation of these research goals is supported by the social and economic impact potential of the project. Namely, inferring the underlying dynamics of social interaction is of outstanding present interest, since it has direct applicability in viral marketing, political science, and even epidemiology, for predicting the spread of a commercial, a rumor, or a virus.

IMPRESS: IMproving the PREdiction of opinion dynamics in temporal Social networks: mathematical modeling and Simulation framework
In a rapidly evolving world, with growing population and accelerated access to online media, the need to understand the structures and behavior of human society has become more important than ever. Having emerged as an interdisciplinary field in the 21st century, social networks analysis is on the quest to understand opinion formation and diffusion from a scientific point of view. The formation of social networks, namely the way connections are created and strengthened, is a very complex process, and there are many factors that interfere for the emergence and evolution of social ties. Notable research efforts try to explain the high complexity of such network structures, by proposing corresponding algorithmic models. Nevertheless, available models have many limitations as they typically assume opinion interaction mechanisms based on fixed thresholds, static topologies, or omnipresent opinion sources.
This project comes to improve our understanding of opinion diffusion in emergent social networks. Consequently, to build models that are aware of these phenomena, I propose fundamental topological analysis of empirical data - using network motifs, community detection algorithms and statistics - to understand the behavioral patterns and centralities which have an impact on spatial and temporal distribution of opinion. As opposed to most existing opinion interaction models, I propose a temporal opinion injection model which evolves over time according to basic human traits and underlying social topology. Also, by employing discrete event simulation on real-time gathered social network data, I propose the implementation of an online platform to offer improved prediction on poll outcomes for socially-relevant topics.
In the wake of big data analytics, this project sets out to push the boundaries of scientific understanding of opinion dynamics in social networks by analyzing how the underlying network topology influences communication patterns and polarization of opinion.
Software Module for Efficiency Assessment of the Hydraulic Pumps in Service for Drinkable Water Systems
A software tool (desktop and mobile) has been developed for the efficiency assessment of hydraulic generators' operation installed in Timisoara's drinkable water system and beyond. The diagnostic is computed based on QR codes and the traffic light system using three colors: green, for normal operation, yellow, for dangerous operation which requires a planned stop and finally red, for abnormal operation requiring an emergency halt.
The diagnostic system has been validated using laboratory experiments and several selected pumps in service for daylight and nighttime use at AQUATIM. Timisoara has more than 300.000 inhabitants, 30.000 foreign students and several hundreds km of pipes delivering drinkable water to the citizens.
The Principal Investigator of the project was interviewed by TeleU about the project results in this video clip:

The objective of this project is to extend the services offered to the clients by the Piconet company, which is the national leader of city surface parking management systems. The aim is to develop a robust method for monitoring the parking occupancy based on processing of images captured by surveillance cameras. This method has to adapt to harsh weather conditions and to changing in illumination due to some natural causes like clouds or artificial ones like public lighting. It also has to adapt to a large variety of cameras’ deployment angles, and to learn environment changes. It has to offer a good support for future extension of services – e.g. automatic car plates recognition or automatic payment methods.
The company plan to use the method developed here to implement a mobile application that can offer an overview of parking occupancy to the clients for an entire area managed by the company. The utility of this solution is to save the client time spent in finding a parking place, especially in crowded central city areas, and it was already requested by many existing clients. Moreover, it will ensure some other benefits like saving the fuel consumption and reducing the pollution generated by cars that creates overhead traffic on the way to find a free parking place. In order to ensure the desired accuracy this method will combine image processing algorithms with existing statistical information collected by the company, and with learned data. In addition it should include a simple and clear procedure for further system deployment.
The result of research will be a functional prototype that can be integrated in the existing company parking management system.
INCEPTION: Internet of Things meets Complex Networks or early prediction and management of Chronic Obstructive Pulmonary Disease
Recent research indicates Chronic Obstructive Pulmonary Disease (COPD) as the third cause of death and one of the main impediments to the quality of living in today’s society. COPD is defined as the clinical condition which reduces pulmonary capacity; it is not reversible, however if diagnosed at an early phase, its evolution can be controlled. Unfortunately, the early detection of COPD is a difficult task, and often time people are diagnosed when they are already in an advanced stage.
Capitalizing on recent research results which indicate sensor systems, mobile, and Internet of Things solutions as very useful for monitoring and managing COPD, we propose a personal, integrated prototype system for early detection and evolution prediction of COPD. As such, we intend to build a sensor network that gathers multiple physiological signals and a mobile application that extracts the multi-fractal spectra as mere signatures of these signals. Then, the mobile system will integrate the physiologic signatures with anthropometric and other individual clinical data. On the server side, we will collect the integrated data from a population of individuals, to build a complex network model of patients. Indeed, recent papers indicate the complex network model as very useful for generating COPD predictions. To this end, we will employ modularity clustering and network layout tools to build prediction models for both early detection and evolution prediction of COPD. The prediction model will be instantiated as a smartphone application and tested in order to assess its predictive capacity.
In order to undertake the objectives of our proposal, we assemble a multidisciplinary team, consisting of computer engineers (hardware and software) and specialized medical doctors. The engineering teams will build the hardware and software parts of our demonstration model, whereas the medical team will provide the necessary medical expertise, in order to test and validate the engineering model.

Wireless networks of sensors and smart devices (WSN) are an extremely interesting topic, at the confluence of engineering fields with enormous impact on worldwide society: digital networks, wireless communications, and miniature embedded digital devices.
Aware of the severe requirements and challenges raised by current applications in this area, we propose a new paradigm - Time and Energy Efficiency (T: or TEE). The goal of the project is to develop an integrated real-time and energy efficient inter-operation framework for networks of smart sensors and devices - TEEFIOS.
The main proposed objectives focus on three distinct layers: (a) T:Node, a hardware-software environment and methodology for designing and assessing real-time behavior and efficient energy consumption of embedded devices, (b) T:YNet, a system for the development and analysis of TEE communication in wireless ad-hoc networks, and (c) T:PIlot, a methodology for the power management of the entire network. An integrated set of tools, benchmarks and databases will also be created to help advanced developers and researchers in the WSN area apply the TEE paradigm to applications with high impact. All the results will be validated using real-life case studies.
Existing resources include a postdoc and PhD students with direct interest in these fields, balanced by senior researchers with high expertise and international visibility, all supported by a well equipped environment - the DSPLabs.
