Pickering Interfaces has expanded its 40- 785B PXI Microwave Multiplexers range with new 50 GHz modules. These new modules are single or dual 6-channel multiplexers with relays mounted on the front panel. They are suitable for switching 50 Ωsignals up to 50 GHz. The single slot version can support up to three remotely mounted multiplexers. Channel setting for all options is indicated by LEDs, a feature...
Context. Considering the importance of software testing to the development of high quality and reliable software systems, this paper aims to investigate how can work-related factors influence the motivation of software testers. Method. We applied a questionnaire that was developed using a previous theory of motivation and satisfaction of software engineers to conduct a survey-based study to explore...
[Background] A high-functioning team is a decisive factor for a successful software development project. However building such a team is not easy. Among many issues and obstacles encountered by teams, social loafing is a common but difficult one to tackle. [Aim] We intend to construct an approach to effectively prevent social loafing behaviors in software development teams. [Method] We built one social...
This is a fact already known by all many companies make large and important disbursements to keep their equipment and information safe from possible attacks and threats that are internal or external. Among the internal threats are the duplication of users, the change of credentials of access to the network, where fraud, sabotage and robberies through the network are actions that need to be faced with...
Test Automation Platform©1 (TAP) is a software system that developers can use to test their own hardware or software (or combinations of both). Developers create TAP test plans by combining and configuring individual test steps in a GUI. Developers can also develop their own test steps with .NET to better suit their needs. Since (manual) programming is always prone to errors, TAP users need...
The paper presents a system that uses Laboratory Virtual Instrument Engineering Workbench (LabVIEW) software to monitor, and to control the state of an electrical machine depending on user imposed limits. In this system, the real-time variables of an electrical machine are measured and transferred to a controller (PC) through Data Acquisition Card (DAQ). The NI USB 6009 DAQ is selected for this project...
In this paper some popular techniques of analog-to-digital converter parameters measurement are compared. The structure of the proposed software-hardware complex and experiment procedure are described. Experimental results are presented.
The water tank system is widely used for demonstration purposes in control engineering. This paper describes a training system for process automation, an ideal way to teach and learn about important aspects of automation. We present the implementation of a micro plant incorporating intelligent instruments. We also describe a set of teaching tools to facilitate the learning of concepts related to linear...
The inclusion of Information Communication Technologies (ICT) in education is something that has been working from different initiatives worldwide. Concern is on how these resources can enhance the teaching-learning process. Video games are an alternative, given that they present an opportunity to work on different themes in a motivating way. Children and young people can access the different contents...
This article aims to present a proposal for the development of a Learning Object called “Anti-Zika”, whose mission is to guide, inform and present relevant contents regarding the combat of the Aedes aegypti mosquito and, consequently, the Zika virus. It is hoped that Health Education will benefit greatly from the proposed Learning Object in order to facilitate and present new ways of transmitting...
Runtime Verification consists in studying a system at runtime, looking for input and output events to discover, check or enforce behavioral properties. Interactive debugging consists in studying a system at runtime in order to discover and understand its bugs and fix them, inspecting interactively its internal state.Interactive Runtime Verification (i-RV) combines runtime verification and interactive...
This research frames a descriptive study that aimed to identify strategies for the implementation of Virtual Learning Objects-VLO-in the Faculty of Humanities of the University of San Carlos of Guatemala; to identify the best strategies, we used the qualitative case study methodology, divided into two phases. In the first one, the video interview technique was applied to experts in virtual learning...
This paper deals with two virtual instruments used for acting and controlling electrical circuits. Due to their working concept, these instruments have high flexibility for improvement, which makes them suitable for developing electro-technical virtual laboratories with affordable hardware and software resources.
Following balance impairments, effective assessment and training of dynamic sitting balance are critical for enhancing functional independence. The objective of this study was to construct and test an instrumented wobble board that elicits multidirectional perturbations in seated individuals, quantifies balance proficiency, and provides vibrotactile feedback. The wobble board was equipped with an...
Beyond providing alternatives to build rubrics, a group of researchers in Tecnológico de Costa Rica found the need to implement best practices in the definition and validation of evaluation rubrics, to encourage the creation of a Higher Education bank of assessment instruments. To achieve this goal, in the Tecnológico de Costa Rica, a teacher training process was established, which includes cooperative-collaborative...
CPS engineers need to possess both technical and social skills to run CPS-engineering projects successfully. Especially social skills are crucial as the project fails are mostly caused because of lacking social skills of project members. Besides strong social skills, CPS engineers need to have a wide range of various technical skills as the products they deal with are getting increasingly complex...
In order to detect the sound signal more real-time and intuitive, a sound acquisition system (SAS) based on data acquisition card is designed. The USB data acquisition card is chosen as the hardware of SAS and the laboratory virtual instrumentation engineering workbench (LabVIEW) is selected as the software of SAS. Finally, the experimental results show that the SAS combined with data acquisition...
This paper presents a proposal of working method for the development of Virtual Instruments. The method is valid with the design of an open source graphical user interface and its implementation as a virtual instrument to acquire the variables of a prototype of an industrial process for stamping parts. The method is developed in four stages: analysis and modeling, design, construction and validation...
In this paper, we designed a real-time data recording system for the characteristics of the three-axis acceleration sensor MSA3000-100. The system consists of low-pass filtering, data acquisition, storage and data analysis. The system master adopts the STM32 chip. Firstly, the analog voltage information outputted by the sensor is pre-processed by the active first-order low-pass filter composed of...
Since software plays an ever more important role in measuring instruments, risk assessments for such instruments required by European regulations will usually include also a risk assessment of the software. Although previously introduced methods still lack efficient means for the representation of attacker motivation and have no prescribed way of constructing attack scenarios, attack trees have been...
