Devices and methods for interaction with a computer do not change very often. However, with technology advancements, solutions for new ways of human-computer interaction are possible. Especially for physically disabled users, solutions for contactless interaction with a device promise new possibilities for independent computer use and management. In this study a solution for a contactless interaction...
Assistive technologies are helping people without speech or functional writing to communicate through alternative methods and devices. The area of study that covers these technologies is called alternative communication. The goal of this paper is to present a new solution that allows people with special needs to use all the features of the keyboard and mouse via sensors connected to a user's body...
In the last two decades the use of technology in art projects has proliferated, as is the case of the interactive projections based on movement used in artistic performances and installations. However, the artists responsible for creating this work typically have to rely on computer experts to implement this type of interactive systems. The tool herein presented, MotionDesigner, intends to assist...
In 1986, this author presented a paper at a conference, giving a sampling of computer and network security issues, and the tools of the day to address them. The purpose of this current paper is to revisit the topic of computer and network security, and see what changes, especially in types of attacks, have been brought about in 30 years. This paper starts by presenting a review of the state of computer...
The functional diagnosis expert system based on knowledge base in the form of neuro-fuzzy network was proposed in this paper. Current values of diagnostic parameters are measured by sensors. The hybrid expert diagnostic system with neuro-fuzzy network knowledge base supports decisions in the situation when the diagnosis algorithm is not known and is formed from the initial data in the form of production...
The Growth in computer technology in all the facets of the world, and life are growing to the point that everyone needs a computer to carry out their work in everyday life. While using the computer for long hours, little is cared about posture, resulting in body ache and some harmful everlasting effects on the body. Computer users can protect themselves from those health risks by implementing proper...
This paper presents a modular designed dynamic positioning (DP) experiment system. Three modules are designed for the DP experiment system, which are onboard computer module, position sensing module and onshore control computer module. The hardware system and software are introduced. A PC/104 computer is used as the main controller of the onboard computer system, and an ARM microcontroller is used...
A versatile framework for automation of sophisticated farm machinery has been proposed in this paper. The paper details the functional design and development of the hardware and software architecture of the framework for electronic monitoring and control of a complex system. The framework aims to provide a user friendly bridge between the digital world and the physical world and covers the core software...
This paper presents a data acquisition and visualization system, with storage in the cloud, applied to photovoltaic (PV) systems. The proposed system uses an embedded computer to perform communication with PV inverters via the RS485 standard. The system developed also performs the acquisition of meteorological data, the computer embedded obtain data by a microcontroller that performs reading of the...
Students at the University of Brasília set out to build a better exercise bike. The Web extra at http://youtu.be/NCSb_sDJL7c is a video demonstration of the Bike-X simulator, a virtual cycling experience designed by engineering students at the University of Brasília's Gama Campus.
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...
Multicopters are lightweight and maneuverable aerial vehicles yet unable to carry heavy payloads, such as large sensors or computers required for indoor autonomous navigation. Therefore, localization is usually performed by using vision-based solutions employing of either lightweight on-board cameras or external fixed cameras and a ground station for data-processing. Nevertheless, the current tendency...
Computing power is increasingly enabling software-based networking. Successful technologies, like Wi-Fi, can now take advantage of the state of the art approaches for software-based architectures, such as software-defined, service-centric, and information-centric networking. In this paper, we employ NovaGenesis — a future Internet architecture — as the foundation for Wi-Fi networks spectrum sensing...
In olden day's machine (lathe or milling machine) movements were operated by manual for that trained persons were required, the workspace and the no of axes were limited one. Productions of complicated parts were difficult and batch production also impossible. The dimensions between the parts were varied so to produce batch production, testing was required. So, the cost of production was increased...
Nowadays, Assistive Technology (AT) systems are closely tied to the devices that they control. Considering a smart environment where a person with a disability needs to interact with multiple devices, the user is forced to rely on AT software tools available on the each used platform. Therefore, computer skills are required to adjust any different computing environment configuration according to the...
Human aspect is considered as one of the success factors for software development. Besides, diversity is labeled as the most effective element for creating effectiveness in team performance. Thus, this study has aimed to find the effects of gender diversity on team performance based on personality types. The personality types' variations were found effective on team performance based on genders. For...
Ground test platform for attitude and orbit control system of small satellite is designed. Hardware interfaces between the real sensors / actuators and the onboard computer is simulated. Satellite dynamic and space environment is calculated in order to form a close-loop control system. Finally, the ground test system is validated by comparing the simulation result and in-orbit flying data.
A quite inexpensive instrument for cervical auscultation is described. Provided you already have a laptop computer, an optional MP3 recorder/player and a copy of your preferred sound analyzing software (e.g. PRAAT), then you just need a common microphone (like one of those ready to be connected to the computer) in a proper encapsulation (described). A complete, effective, reliable and state of the...
Topics include malicious-advertising attacks inflicting ransomware on victims, an application that promises to predict Ebola outbreaks, the US rejecting more software-patent applications than in the past, China reportedly attacking Apple's iCloud, a game company forcing the shutdown of a gamebot maker, new Ethernet versions that are on the way, wearable technology that adheres to the user's skin,...
The rapidly changing needs of modern education can be effectively supported by today's small, intelligent devices including tablet PCs, smart phones programmable routers and credit-card sized computers like the Raspberry PI. Since there are many available sensors on the market, it is rather easy to connect real world signal to these devices like temperature, light intensity, acceleration and many...
