The petroleum industry includes the processes of exploration, extraction, refining and transportation. In the areas mentioned above there must be an efficient lighting that provides the minimum lighting levels in the work plane, according with the standards applicable to petroleum facilities, this is accomplished by setting the specifications, methods and technical guidelines which must meet the petroleum...
Actually, the measurement of physiological data of patients in health centers of Ecuador is done manually which imply much time for reception and reduced mobility. To minimize these problems has been considered implement an electronic system to perform these tasks quickly and safely. This research seeks to improve the response time in decision-making, patient monitoring. This design consists of an...
The full squat technique is evaluated through a pattern graphic and by comparing the same exercise in three different styles, looking for similarities for the described path by the bar and comparing the minimum dots of close of the angle formed by the hip and the angle of the knee. The person who best develops the exercise is determined because of their similarity to the pattern graphic.
Engineering students majoring in instrumentation and control require training modules to realize practices in industrial processes and automatic control. Usually these modules are expensive and most are designed to control a single variable. In the present work we design and built a low-cost training module, which makes possible to realize labs practices in the industrial process control area, with...
We present an artificial vision based system that quickly and semi-automatically calibrates water meters. The system operates with an artificial neural net architecture which is able to visually read analog needles and dynamically track the float position of a lab rotameter. By using a closed water flow circuit powered by a low power centrifugal pump, the computer reads through a web camera the water...
This paper discusses the development of a software capable of extracting geometrical properties of sugar crystals, using artificial vision tools available in MatLab, which provides a more accessible and easier option to develop the quality control processes in sugar mills.
The medieval Church of Zelemér was located in the Great Hungarian Plain, approximately 200 km to the east of Budapest, the capital of Hungary. Nowadays, only the ruins of the church exist and there is no accurate description about the original building. The place and the church itself have religious and historical importance, its ruins and surroundings are frequently visited by tourists. There have...
In this paper we implemented a system of fisheye vision (a 360° × 180° visual field) for georeferenced tracking of feature points associated with moving objects in urban scenes. To develop this system: 1. We calibrate the intrinsic parameters of a fisheye camera based on the stereographic model. 2. We propose a geometric model of image formation and adjust the position and orientation parameters using...
This paper shows the technological web platform "MEGARUTA. CO". The platform is a modular application that manages: planning, control and user information of the integrated public transport system (SITP) of the West Central Metropolitan Area in Colombia. The platform has two access portals, the first is for the user of the SITP where he can plan his travel within the system (web portal)...
Linguistic word nets usually focus on the semantic content and content relations of nouns while not taking into account to what degree those nouns can also reflect visual impressions in a user specific manner. Recently Color Design SNS like COLOURlovers or Adobe Color CC have gained popularity and the huge corpus of available data allows for gaining new insights into the way user associate color designs...
In an execution of a large scale program, even a simple observable behavior may be generated by a wide range of the source code. To comprehend how such a behavior is implemented in the code, a debugger would be helpful. However, when using a debugger, developers often encounter several types of cumbersome tasks and are often confused by the huge and complicated runtime information. To support such...
While constructing and evolving software systems, developers generate directly and indirectly a large amount of data of diverse nature, such as source code changes, bug tracking information, IDE interactions, stack traces, etc. Often these diverse data sources are processed and visualized in isolation, leading to a partial view of systems. We present a blended approach to visualize several data “ingredients”...
Rapid serial visual presentation based brain-computer interface (BCI) system relies on single-trial classification of event-related potentials. Because of large individual differences, some labeled subject-specific data are needed to calibrate the classifier for each new subject. This paper proposes an online weighted adaptation regularization (OwAR) algorithm to reduce the online calibration effort,...
We give an overview of engagement in human-agent interaction. We discuss the different definitions of engagement in human and social science, specify how they relate to certain other concepts, and give an overview of the high level behaviour that is often associated with engagement. This work serves to position our future research on engagement in human-agent interaction.
Mimicry and laughter are two social signals displaying affiliation among people. To date, however, their relationship remains uninvestigated and relatively unexploited in designing the behaviour of robots and virtual characters. This paper presents an experiment aimed at examining how laughter and mimicry are related. The hypothesis is that hand movements a person produces during a laughter episode...
In this paper, we study perception of intensity in-congruence between auditory and visual modalities of synthesized expressions of laughter. In particular, we investigate whether incongruent expressions are perceived as 1) regulated, and 2) unsuccessful in terms of animation synthesis. For this purpose, we conducted a perceptive study with the use of a virtual agent. Congruent and incongruent multimodal...
Software engineering tasks like understanding of (legacy) software, checking guidelines, finding structure, or re-engineering of existing software require the analysis of the static software structure. The optimal visualization of this structure depends on the task at hand. In general, the software structure is mapped to a graph and graph drawing algorithms are used for displaying the structure. The...
We present LISSA — Live Interactive Social Skill Assistance — a web-based system that helps people practice their conversational skills by having short conversations with a human like virtual agent and receiving real-time feedback on their nonverbal behavior. In this paper, we describe the development of an interface for these features and examine the viability of real time feedback using a Wizard...
Pixel expansion is a common drawback of traditional (2,2) visual secret sharing (VSS), unexpanded shares can decrease the bandwidth and save storage. In the literature, we introduce a novel (2,2) VSS scheme, that solved the pixel expansion and visual quality is almost equal with traditional (2,2) VSS. Our scheme not only can apply to (2,2) VSS, but also to (k, k) VSS. At last, analyse and experiment...
