A comparison of different bio-inspired methods is presented for the problem of tuning the parameters of a PID industrial controller for second order plus time delay plants. The compared algorithms are representative of ...

This paper presents a formulation for the inclusion of the second degree of freedom for MIMO system for decoupling purposes. The proposal is specially effective when combined with decentralized feedback controllers. Loop ...

In this paper the Enhanced Normalized Normal Constrained method is applied to find the optimal tuning of second order PID controllers. This tuning takes into account both the servo and regulatory modes simultaneously, as ...

Results from the use of UAV-based photogrammetry for monitoring changes in beaches and breakwaters are presented. Main recommendations are provided on the basis of lessons learned about the collection of reliable results ...

Program visualizations help students understand the runtime behavior of other programs. They are educational tools to complement lectures or replace inefficient static drawings. A recent survey found 46 program ...

We focus on the discussion about the proposal of shifting to a post paid mobile Internet tariff model based on usage, and its impact on universal use and service access for the poor sectors of the country. This proposal ...

GQM+Strategies is an approach that aligns the business goals at each level of an organization to strategies and assesses the achievement of goals. The IDEAL model is an organizational improvement model. In this paper, ...

Gender digital equity in Latin America and the Caribbean is our goal. We analyze gender specific structural inequalities that constitute barriers for women’s access to ICT: such as education, traditional cultural beliefs ...

The use of smart devices is increasing rapidly; this trend is changing the paradigm in which notifications are delivered to users. Smart devices are important to provide user awareness. However, their use must be controlled ...

An irrational fear is called a phobia. Cognitive therapy teaches patients how to respond to triggering stimuli, by relaxing their mind and entering a state of reduced anxiety. Some of these methods depend on patient’s ...
