Collaborative learning is proven to be effective in improving cognitive skills (e.g., critical thinking) and acquiring knowledge through group interactions and activities. An active research field known as Computer Supported Collaborative Learning (CSCL) aims to enrich collaborative learning using technology. These days, online learning environments equipped with various communication tools (e.g.,...
This paper presents several results regarding a number of applications based on instrumental Internet of Things (IoT), namely an indoor environmental monitoring solution, a solution for detecting the presence of a human being and an application that centralizes the signals transmitted from a large set of astro-particle detectors placed on a large area observatory to a central unit.
Strategic planning processes are among the most demanding tasks that managers face in today's complex market place. Strategic planning is most effective when implemented as an integral part of institutional decision-making, not as a separate formal, comprehensive activity. Measuring and managing performance is a challenging enterprise and seen as one of the keys to managing change and thus gaining...
The nascent field of entrepreneurship is growing rapidly and attracting increased attention from many sectors, which developed ten evaluation indicators continuously. In spite of the lack of a comprehensive comparison, rankings from those measurement indices were extensively used for investigating, evaluating, and adjusting entrepreneurial policies in different countries. Based on the criteria of...
In this paper we present a new gamified learning system called Reflex which builds on our previous research, placing greater emphasis on variation in learner motivation and associated behaviour, having a particular focus on gamification typologies. Reflex comprises a browser based 3D virtual world that embeds both learning content and learner feedback. In this way the topography of the virtual world...
This paper presents a few aspects regarding the modelling, simulation and monitoring of dynamic regimes for asynchronous motors. There are presented the two-axes mathematical model of these motors, the Simulink simulation program, the simulation results for the case of direct on-line starting, as well as a few experimental results (which confirm the simulations). The research originality derives from...
In dense mobile wireless sensor networks, it is desirable to reduce traffic for data gathering as much as possible while satisfying an application requirement. In this paper, focusing on an application which monitors the time-variant shape of events, we discuss an approach to achieve an efficient monitoring with small traffic in dense mobile wireless sensor networks.
This paper introduces the progress of circularly polarized synthetic aperture radar (CP-SAR) development under collaboration of Chiba University and Ajou University for unmanned aerial vehicle (UAV, JX series) and microsatellites (GAIA series). This sensor will be employed to monitor global disaster area in the future.
Through scene construction and intelligent interaction in a 3D virtual world environment, we developed the project "Confucius' Journey". Considering the problems in such applications, such as the lack of interaction and reduced effectiveness in representing the application purpose, we explored interactive objects and virtual human technology. In addition, we can verify the advantage of using...
Researchers frequently have to execute simulations that are computationally expensive. Instead of using dedicated computers to execute extensive simulations, our HTCondor system assigns these jobs to a pool of undedicated computing nodes. These computing nodes work on the submitted tasks and report the results back to the user. This paper examines the performance of an HTCondor system at our university...
The authors of the article consider the peculiarities of data processing of space monitoring of territories with the purpose of prevention of technogenic emergencies. The article is devoted to the study of interferogram, located on the territory of the Karaganda region.
Governments and agencies worldwide have used social welfare programmes as a means of improving the lives of vulnerable people. In Latin America and the Caribbean, conditional cash transfers (CCTs) have been used to change the dynamics of responsibility between state and beneficiary by instituting conditionalities. In order to maintain the integrity of these programmes, social workers are required...
Reactive power is an essential part of the power compared with active power. It is used to establish and sustain the magnetic field present in electrical equipment possessive of coils, such as transformers and electric machines. The reactive power consumption in large distribution networks can result in a huge reactive power flow, rising line current and a sub-nominal voltage. To avoid these negative...
Learner's knowledge assessment is very important in the e-learning system. Knowledge assessment is effective for knowledge gap discovery. Knowledge gap, Causes the learners do not understand educational content correctly. This paper presents a new method for learner's knowledge modeling based on knowledge gap discovery for concepts of educational content. There are two methods for learner's knowledge...
When accidents or large fires occur, rapid and appropriate rescue operations should be taken in the scene. It is very important for such operation that rescue team members constantly communicate with each other in the site. Moreover the base station located near the site should be aware of the team members' positions and situations to direct them effectively. A remote monitoring system with ZigBee...
A major problem besetting sub Sahara Africa is the non-availability of information of the exact problem being faced by the people in rural areas. There have been serious efforts both by the government (local/international) and international donor agencies to tackle these problems head on by providing infrastructure development, affordable health care delivery and education of the populace.
MyHeart is a telehealth system designed to bridge the current gap in the Congestive Heart Failure care continuum that occurs when the patient transitions from the hospital to the home environment. The system uses wireless health devices and a mobile application on the patient's end, a rule-based expert system, and a dashboard on the clinician's end to facilitate the exchange of information pertaining...
Modern video surveillance systems need to acquire clear video images of the interest targets in wide range scene, which usually have some difficulties only by changing the cameras focal length when the targets distance and constantly move. In order to obtain details of the features of long distance moving targets in wide range of monitoring scene, we use a panoramic camera and Intelligent Speed Dome...
Students' goal orientations impact their self-regulation, engagement, and achievement in post-secondary STEM courses. But, how students' goal orientations change across a semester and the impacts of these changes have not been extensively studied. Study purposes were to investigate goal orientation change across the semester, associations of goal change with achievement and self-regulation, and associations...
In this work-in-progress, an educational tool based on a PSpice photovoltaic (PV) module simulation model is presented. An innovative practice relies on a monitoring system for PV applications that supports this didactic tool. The monitoring system manages to provide real data about the performance of the PV module such as irradiance, ambient temperature and the current, voltage and power of the PV...
