This paper aims at the actual demand for experimental teaching for sensors and detecting technologies. It adopts LabView as virtual instrument platform, taking embedded processing system as hardware platform and designs the experimental teaching platform for detecting voltage and frequency signals of sensor output. We pay attention to the teaching demand and discuss the design idea and overall structure...
The purpose of this research is to examine elementary and middle school teachers' readiness as online learners by developing the Teacher Readiness for Online Learning Measure (TROLM). This paper draws on the two semesters of 2012 from an online course on Internet literacy and ethics for practicing teachers. Results of exploratory factory analysis support an 18-item scale comprising four factors: communication...
This paper presents the design, development and evaluation processes of Musikinésia, an educational digital game idealized to support Music students to identify music notes and keys in a music keyboard. In this context, the game aims in developing the ability of identifying music notes on the instrument based on the reading of a music sheet and other basic concepts, such as music reading in G clef,...
This paper presents a software application for studying of the most used methods for text encryption/decryption, with utilization in teaching activities and didactical laboratories. The applications is realized using virtual instrumentation software and was designed as a didactical software platform for studying and analyze the two of the most used encryption techniques, the symmetrical and asymmetrical...
This study aimed to propose and test a model of acceptance of online learning by face-to-face students. Participated in the research, conducted through survey technique, 732 students attending 1st cycle courses (bachelor) in 11 Portuguese private higher education (HEIs). Built a acceptance of online teaching model (MAEO) based on four dimensions: perceived usefulness, attitude, technological expertise...
Using scientific disciplines as inspiration, some researchers have called for the creation of general theories for software engineering. I present a contrary view, drawing on recent work in the philosophy of engineering. Engineering theories are different to scientific theories, and are not judged by the same criteria. Software engineering researchers should strive to create valid theories about the...
We describe the physical and operational characteristics of an autonomous platform for ocean observation which has considerable potential for tracer dispersion and gas exchange studies. The Dorado (International Submarine Engineering, Port Coquitlam, B.C.) is an 8.2 m long, 1.2 m in diameter, snorkelling, semi-submersible vehicle powered by a 315 kW Caterpillar marine diesel engine. Capable of cruising...
This paper proposes the development of mathematical reasoning in undergraduate students through vector cryptography implemented in a software system. Mathematical reasoning is a cognitive function that could be improved using symmetric encryption techniques such as Hill Cipher, which implements the operations of the linear arithmetic spaces. The goal of this research project is that undergraduate...
One of the main problems of current system design and architecture tools is the communication between the tool and the user and vice-versa. The tools are too opaque, and the users often don't understand their outputs, which results in loss of confidence in the tool. The users are also frustrated because they don't have an effective way of providing their expert knowledge (acquired either in real time...
Many researches have been addressed on design approach for speech enhancement. They are mainly focus on speech quality and intelligibility to produce high performance level of speech signal. Wiener filter is one of the adaptive filter algorithms to adjust filter coefficients and produce an output signal that satisfies some statistical criterion. The objective measures will optimize using informal...
Human Gait Recognition is typically alluded to imply the human ID by the style/way individuals stroll in picture sequences. Our point is to execute the customary gait recognition calculation and to demonstrate the variety in recognition when subject is watched parallel to camera under three conditions-walking slow, at typical speed and walking quickly. For this situation, the work devises a novel...
With the advances of technology, gaze is becoming increasingly an attractive and viable interaction method in games. In particular, gaze is likely to provide a natural way of interaction in some games. However, little work has been done to design games that use gaze as an interaction method and test users' reactions to it. Additionally, despite the fact that Generation Y and Baby Boomers form a sizable...
Cloud computing encourages the prototype for data service outsourcing, where data owners can avoid cost usage by storing their data in cloud storage centers. The ultimate problem of cloud computing technology is that, the service providers have to protect the user data and services. Secured systems should consider Confidentiality, Availability and Integrity as their primary option. The user encrypts...
In this paper we describe some of the work taking place in a system to create an affordable setup for a remote laboratory. The system utilizes HTML5 and JavaScript to make the user interface accessible on various platforms, including mobile devises and computers, without any additional software installation. The system comprises a remote laboratory for configuring and analyzing a simple power supply...
A fully programmable digital instrument for the emulation in real-time of signals with bandwidth up to 400 MHz from generic radiation detection systems is presented. The instrument is not a pulse generator of recorded shapes but a synthesizer of random pulses compliant to programmable statistics for height and starting time of events. Completely programmable procedures for emulation of several noise...
Resiliency has been built into airframes and systems with accelerating success. The art of building resiliency into the human element on the flight deck has also advanced since the days of lone pilots, but not as dramatically. The teamwork of Captain and First Officer has achieved much, even recovering from the removal of Second Officers after their flight engineering tasks became largely automated...
In the past decade, a wealth of new resources have become available to students in tertiary education. Some of these have been designed to assist teaching and learning, whilst others, such as social networking sites and the wide availability of mobile devices, have become ambient in our students lives. The impact of this on us (as academics), is that the academic study (of computing, in our case)...
This paper illustrates the components, capabilities, and some characteristic applications of the Woods Hole Oceanographic Institution Jetyak — a small autonomous surface vehicle (ASV) designed for the collection of oceanographic data from shallow or dangerous waters. The Jetyak is the result of custom modifications to a Mokai jet-powered kayak, including an A-frame and sea chest for installation of...
The instruments BCI (brain-computer interface), are currently breaking into the vast horizon of bioengineering, favoring people with brain deficiencies, which sometimes is the only way to communicate. The main objective is to acquire brain signals to achieve an interface capable of receiving a response from the computer; and control a robotic arm. This paper provides a description of brain signals:...
The general purpose Automatic Test System included the general purpose instruments and the special purpose Test Unit Adapter (TUA). With the increasing types of the unit under test, the number of the TUA was increasing too, eventually leading to huge automatic test system. The main idea of this research is removing TUA and connecting the instrument and the equipment under test directly. So the volume...
