ConCIENCIA Estadística is a digital educational material proposed as support for the development of the homonymous workshop, organized in the framework of the Project for Improvement of Training in Exact and Natural Sciences in the Secondary School (Facultad de Ciencias Exactas y Naturales, Universidad Nacional de La Pampa). This material is described in this paper, offering technical details of its...
The need for the reduction of energy consumption and size of microelectronic circuits is increasingly in demand. To support this request, this paper presents a comparison study on two integrated technologies: FDSOI 28nm and CMOS 350nm. The aim of this work was to compare the performance of these two technologies for the design of a rectifier and a Dickson charge pump for rectenna application. The...
Changes in higher education are not only technology-driven but even more by societal changes. As generation Y and Z enter the universities, other requirements have to be met, because their learning expectations differ from requirements of former generations. Many scientists highlight the effectivity of new teaching methods especially for higher education. The question is if positive effects are noticeable...
Despite reusability being a Learning Objects (LO) core feature, sometimes they demand modifications to fit the new use context. This adaptation process must be easy and rapid. However, several LO are produced in a way that changes need to be done at source code, requiring technical knowledge. Guided Customization (GC) aims at enabling the user to execute adaptations without this requirement. It allows...
Our work aims at helping teachers to monitor learners' engagement during mind mapping activities. The use of mind maps helps students to elaborate cognitive learning strategies like creating and organizing contents. To assess the quality of these mind maps, teachers need tools to understand students' choices and strategies when constructing their mind maps. We have defined in collaboration with teachers...
In this paper, a novel steganography algorithm based on an improved "Matrix Pattern" (MP) method is presented. In this process, firstly, an RGB image is divided into the non-overlapping square-sized blocks. Next, 95 dynamicsized unique matrix patterns are automatically generated using the 4th and 5th bit layers of the green layer of each block, which are assigned to 95 English keyboard characters...
Despite the rapid progress of the techniques for image classification, video annotation has remained a challenging task. Automated video annotation would be a breakthrough technology, enabling users to search within the videos. Recently, Google introduced the Cloud Video Intelligence API for video analysis. As per the website, the system can be used to "separate signal from noise, by retrieving...
The article is devoted to investigation of the influence of secondary vibration modes in the uniformity of the working ring disk mode ultrasonic radiators. In the first part the article refers to application of ultrasonic vibrations for various processes intensification. Further article considers methods, allowing reduce quantity secondary mode in investigated frequency range, which can render influence...
This paper presents a new mechanism of reusing and value-added mechanism to the digital archived contents of the National Education Radio, as its interactive nature diffuses it from traditional attempts in the past. Aiming to improve the quality of user experiences, relevance of their content and expand on their target audience, our research team mediates by incorporating the design thinking method...
This paper presents unsupervised algorithms to uncover polarization in social networks (namely, Twitter) and identify polarized groups. The approach is language-agnostic and thus broadly applicable to global and multilingual media. In cases of conflict, dispute, or situations involving multiple parties with contrasting interests, opinions get divided into different camps. Previous manual inspection...
Strategies and policies to bridge identified and potential digital divides is a core challenge when forming an inclusive and participatory digital democracy and society. In line with the progress and development of digital technologies and applications governments have to address digital divides. This project discusses how social and digital divides have been addressed in a project called "The...
The new approach for creating the non-homogeneous media with specific refraction coefficient is proposed. The electromagnetic wave scattering problem is solved at condition that the embedded in the initial homogeneous media bodies are small and described by their surface impedance. The numerical results confirm the possibility to create the media with the new refraction coefficient that changes in...
Mobile messaging applications are already a part of everyone's daily life. Despite their prevalence, we have limited knowledge on user behavior and data transmission performance of these services. In this paper, we examine WeChat, one of the largest mobile messaging services with over 800 million active users. To this end, we analyze a packet-level dataset captured in a cellular network, containing...
Due to the continuous upscaling of the storage capacity and downscaling of the physical size of storage systems, the data reliability problem has become a research highlight. While various redundancy schemes have been proposed to include extra redundant data to ensure that the correct data can be recovered even in the presence of bit errors or bad blocks, they might introduce unexpected performance...
Due to the excellent performance and energy efficiency, modern nonvolatile memories (NVMs) have become popular alternatives to DRAM as main memory. However, the intrinsic characteristics of NVMs are quite different from those of DRAM, making existing designs of system and application software unfavorable on NVMs. For example, a write operation typically takes much more time and energy than a read...
The focus of this research was to explore the language function and application via SCAN Model, Six Creative, and Assimilated Navigation, SCAN model, covering the six cultural metaphorical factors: TIME, SPACE, BODY, VISION, EMOTION, and SOCIALIZATION aspects. The SCAN model was employed as a medium to stimulate the participants to illustrate their perspectives regarding the issues of language function...
With the generalization of information and communication technology, instant messaging (IM) has emerged as a tool for synchronous and asynchronous communication in recent years. Among all of the IM applications, Line and Skype are the most frequent used in corporate internal communication. As IM has become one of the necessary means for communication upon workplace, its appearance is also gradually...
Aesthetic patterns are formed into different systems due to different regional customs, and the language of the contemporary presented by a work could be understood by aesthetics analysis. Poster is a printed media that massively passes messages to the public, it works like a barometer to reflect politics, economics, cultural and arts events of each period in timely manner, and this is particularly...
Modest fashion is driven by underlying Islamic mandate to preserve modesty, as laid forth in the Quran and the Sunna. Especially for women, they should cover the body from head to hands and feet. As majority religion in Indonesia, the developing of modest fashion has been growing rapidly. The appearing of new designers who create new modest fashion styles have been contributed to development of modern...
