Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
In this paper some methods of ultrasonic signals energy estimation are presented. The origin of this study is a target strength and distance estimation using air coupled ultrasound sensors applied in ie. proximity sensors. In the pulse echo mode based systems the echo detection is based on signal threshold signal estimation. The signal threshold is associated with the signal energy, what implies incorporation...
A major drawback of orthogonal frequency division multiplexing (OFDM) is the frequency offset sensitivity. It mainly leads to inter-carrier interference, which can effectively be reduced by employing the pulse shaping filter method. In this manuscript, we present and then optimize the improved double-jump 1 (IDJ1) pulse for digital video broadcasting over cable 2 OFDM systems. Our function is finally...
Nowadays, many requirements must be fulfilled in relation to the application of agrochemicals in different productive stages of the export fruit in Chile. Agronomists in charge of productive orchards should consult different sources of information before proceeding to apply a certain product. This is based on technical guides and protocols that are also modified from time to time, which implies a...
Emotions are directly related whit external or internal stimulation which a person is submitted, influencing these stimuli on their physical and mental health. These emotional changes produce variations in cardiovascular behavior and respiratory activity. This research proposes the characterization of cardiac system in healthy subject submitted to 3 different audiovisual stimuli, by means of the analysis...
In this paper we present an optimization algorithm for simultaneously detecting video freeze and obtaining the minimum number of the frame required in motion intention estimation for real time robust video stabilization on multirotor unmanned aerial vehicles. A combination of a filter and a threshold is used to the video freeze detection, and for optimizing the algorithm, we find the minimum number...
The imminent arrival of advanced technologies in the field of telecommunications would give impulse to upgrade coherently the content of the topics of the last year of the electrical and network engineering program. For instance, the new topics based on the so-called nanocommunications networks might play a crucial role in the field of the medicine. It would demand to implement dedicate networks to...
This paper presents a speech interface to extract domain-specific information from a tourism semantic website as a way to avoid complicated and unfriendly SPARQL queries. First, we present a user-oriented website with a semantic knowledge model of tourism. This model is also known as ontology, represents a common understanding of domain in which semantics of data is machine understandable. Second,...
A human-like mobile robotic system for humus production, from earthworms (Eisenia foetida), in urban areas, was developed, built up and tested. The system could be separated in two modules for a better understanding, Software and Hardware. The Software implements a fuzzy control algorithm aimed to keep the best environment conditions inside the humus production zone, an in this way maximize the humus...
Pollutants inside at houses are smoking, gas combustion, use of solvents, household cleaning chemicals, emissions from building materials, and contamination of the exterior aggravates the inside of the house. In this article, we conducted a study to select the best air purifier equipment for an urban house. The selection was carried out by applying the analytic hierarchy process (AHP) methodology...
This paper focus on the robustness analysis inverse problem of linear electric circuits. The aim is to determine what amount of variations of the input parameters can an electrical or electronic system tolerate, such that the output variables (e.g. conducted noise) does not exceed an upper bound in the frequency domain. Based on the well-known theory of robust control and convex optimization, we propose...
During the past thirty years there has been enormous interest in the detection of odours by means of electronic instrumentation. This has led to the development of devices called ‘electronic noses’ that typically include an array of selective sensors with a pattern recognition software. The present work describes the design process of an electronic nose prototype for explosive detection. The implementation...
The integration of wind power into power systems has economic components that must be considered. In particular, the line connecting one the power plant with the electric system may present tradeoffs that needs to be analyzed. On one hand, the line can be dimensioned to carry the maximum capacity of the wind power plant; if the occurrence of maximum output from the resource has low probability, the...
An interesting application of the prospective technology called Internet of Bio-Nano Things (IoBNT) is in the territory of the medicine. It's expected that this technology plays the role as tool of surveillance of the functionalities of the human organs. To accomplish that, the deployment of nanodevices very near to organs should be a must. However, the idea to deploy nanodevices should be sustained...
The quality control of cherries harvested in the orchard is a process of great relevance for the Chilean export industry. Nowadays companies carry out this process manually, obtaining a high error rate in the measurements of color and caliber of the fruits. This article seeks to develop a system to automate this process and thus reduce measurement failures. For this, an information system was implemented...
