Design of a Secure Three-Factor Authentication Scheme for Smart Healthcare.

Abstract: Now-a-days, the society is witnessing a keen urge to enhance the quality of healthcare services with the intervention of technology in the health sector. The main focus in transforming traditional healthcare to smart healthcare is on facilitating the patients as well as medical professionals. However, this changover is not easy due to various issues of security and integrity associated with it. Security of patients's personal health record and privacy can be handled well by permitting only authorized access to the confidential health-data via suitably designed authentication scheme. In pursuit to contribute in this direction, we came across the role of Universal Serial Bus (USB), the most widely accepted interface, in enabling communication between peripheral devices and a host controller like laptop, personal computer, smart phone, tablet etc. In the process, we analysed a recently proposed a three-factor authentication scheme for consumer USB Mass Storage Devices (MSD) by He et al. In this paper, we demonstrate that He et al.'s scheme is vulnerable to leakage of temporary but session specific information attacks, late detection of message replay, forward secrecy attacks, and backward secrecy attacks. Then motivated with the benefits of USB, we propose a secure three-factor authentication scheme for smart healthcare.

BinDash, software for fast genome distance estimation on a typical personal laptop.

Abstract: MOTIVATION The number of genomes (including meta-genomes) is increasing at an accelerating pace. In the near future, we may need to estimate pairwise distances between millions of genomes. Even with the use of cloud computing, very few softwares can perform such estimation. RESULTS The multi-threaded software BinDash can perform such estimation using only a typical personal laptop. BinDash implemented b-bit one-permutation rolling MinHash with optimal densification, an existing data-mining technique. BinDash empirically outperforms the state-of-the-art software in terms of precision, compression ratio, memory usage and runtime according to our evaluation. Our evaluation is performed with a Dell Inspiron 157 559 Notebook on all bacterial genomes in RefSeq. AVAILABILITY AND IMPLEMENTATION BinDash is released under the Apache 2.0 license at https://github.com/zhaoxiaofei/BinDash. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

Student Engagement Detection Using Emotion Analysis, Eye Tracking and Head Movement with Machine Learning.

Abstract: With the increase of distance learning, in general, and e-learning, in particular, having a system capable of determining the engagement of students is of primordial importance, and one of the biggest challenges, both for teachers, researchers and policy makers. Here, we present a system to detect the engagement level of the students. It uses only information provided by the typical built-in web-camera present in a laptop computer, and was designed to work in real time. We combine information about the movements of the eyes and head, and facial emotions to produce a concentration index with three classes of engagement: "very engaged", "nominally engaged" and "not engaged at all". The system was tested in a typical e-learning scenario, and the results show that it correctly identifies each period of time where students were "very engaged", "nominally engaged" and "not engaged at all". Additionally, the results also show that the students with best scores also have higher concentration indexes.

Personal volunteer computing

Abstract: We propose personal volunteer computing, a novel paradigm to encourage technical solutions that leverage personal devices, such as smartphones and laptops, for personal applications that require significant computations, such as animation rendering and image processing. The paradigm requires no investment in additional hardware, relying instead on devices that are already owned by users and their community, and favours simple tools that can be implemented part-time by a single developer. We show that samples of personal devices of today are competitive with a top-of-the-line laptop from two years ago. We also propose new directions to extend the paradigm.

Real Time Tracking and Alert System for Laptop through Implementation of GPS, GSM, Motion Sensor and Cloud Services for Antitheft Purposes

Abstract: This paper report explains the methodology to track a stolen laptop through the implementation of GPS, GSM, Motion Sensor, and Cloud Services. Unlike other existing laptop tracking techniques available in the market, the methodology mentioned in the paper tracks the laptop even if it is not connected to the internet or is in turn off mode. With the implementation of IoT, the owner will be able to track his or her stolen laptop the moment it makes a small movement and can trigger an alarm that will be embedded in the laptop. The alarm will make noise audible up to 10 meters that will make the thief think twice before carrying the laptop with himself. Meanwhile the owner will also be able to monitor the location of his or her stolen laptop through the mobile application installed on his or her phone by communicating with the GPS and GSM modules embedded in the laptop, through the cloud.

Using the Soar Cognitive Architecture to Remove Screws From Different Laptop Models

Abstract: This paper investigates an approach that uses the cognitive architecture Soar to improve the performance of an automated robotic system, which uses a combination of vision and force sensing to remove screws from laptop cases. Soar’s long-term memory module, semantic memory, was used to remember pieces of information regarding laptop models and screw holes. The system was trained with multiple laptop models and the method in which Soar was used to facilitate the removal of screws was varied to determine the best performance of the system. In all the cases, Soar could determine the correct laptop model and in what orientation it was placed in the system. Soar was also used to remember what circle locations that were explored contained screws and what circles did not. Remembering the locations of the holes decreased a trial time by over 60%. The system performed the best when the number of training trials used to explore circle locations was limited, as this decreased the total trial time by over 10% for most of the laptop models and orientations. Note to Practitioners —Although the amount of discarded electronic waste in the world is rapidly increasing, efficient methods that can handle this in an automated non-destructive fashion have not been developed. Screws are a common fastener used on electronic products, such as laptops, and must be removed during nondestructive methods. In this paper, we focus on using the cognitive architecture Soar to facilitate the disassembly sequence of removing these screws from the back of laptops. Soar is able to differentiate between different models of laptops and store the locations of screws for these models leading to an improvement of the disassembly time when the same laptop model is used. Currently, this paper only uses one of Soar’s long-term memory modules (semantic memory) and a screwdriver tool. However, this paper can be extended to use multiple tools by using different features available in Soar such as other long-term memory modules and substates.

Co-located Collaborative Block-Based Programming

Abstract: With the increasing need to teach programming to novices using collaborative methods like pair programming, it is important to understand how different input devices can help support collaborative learning. In this paper we present Multi-Device Grace, the first application to explore block-based programming in a cross-device environment consisting of digital tabletops, mobile tablets, and laptops. We conducted a user study $(n =18)$ to explore how cross-device environments can support co-located collaborative block-based programming. The study used Tiled Grace, an existing block-based programming language, and our extensions: Tabletop Grace (designed for tabletops) and Mobile Grace (designed for tablets). Our results show that the majority of participants felt they were able to collaborate quickly and easily, and the cross device interaction would be particularly beneficial in an education setting. Fig. 1.Multi-Device Grace: multiple novice programmers simultaneously working together on different devices (laptop, mobile tablet, and digital tabletop) within different independent workspaces to develop a new blocks-based program.

Flexible & customisable human computer interaction (HCI) device that combines the functionality of traditional keyboard and pointing device (mouse/touchpad) on a laptop & desktop computer

Abstract: Humans interact with computers using various input/output peripherals e.g. keyboards, touch pad, stylus, mouse and touchscreen etc. This novel HCI device, eliminates the physical limitations of traditional input methods i.e. keyboard & pointing devices like touchpad & mouse. This HCI device enables customisation of input for every & the specific use case. The HCI device operates in full touch pad mode, keyboard only mode and traditional mode. Based on specific triggers/conditions the switch between modes is quick and smart. The flexibility and hardware independence is achieved by replacing mechanical hardware with new non-mechanical touch based hardware and software that governs the new hardware. Different modes of operation are actuated based on the operational requirement, customisation &/or user preference. A trigger to initiate a mode is calculated by a combination of multiple sensor inputs, active software application, hands spatial location on pad, stylus state, buttons, gestures performed and user preferences. The novel HCI is either integrated into the laptop or in a standalone unit to fit existing laptops and desktops. The new HCI device provides independence from physical mechanical hardware limitations and provides unlimited customisation. This makes the new HCI device future proof and a true universal alphanumeric and pointing input instrument.

Smart Class Applications for Education

Abstract: We use technological developments in education and adapt technology to education. Educational computers, tablets, smart phones and other technological devices that integrate with these devices aim to increase the quality of education within the scope of computer-aided training. At the same time, with the development of the Internet, it has become much easier to access resources. The environments where the hardware and software technologies used in education are used together can be considered as intelligent classes. Video conferencing and live broadcasts used in the first smart classrooms have now turned into different applications. Intelligent classes that support learning with robotics, mobile learning, virtual reality and augmented reality applications, and different learning environments and materials are used today to improve the quality of education. The Individualized Smart Class (BAS) application proposed in this study is designed in two steps, hardware and software. It is envisaged to use laptop computers, microphones, headphones, tablets and virtual reality glasses in the classroom as hardware. At the same time the broadband of the classes will be ensured to have the internet. Even in this class, wireless network systems such as infrared, Bluetooth, Wi-Fi can be used. As a software, a class that can be included in the virtual classes with cloud architecture and can use the increased reality applications is considered. In addition, mobile applications that provide virtual reality will enrich the course materials. With this application, equality of opportunity will be provided for disadvantaged students in education and training, quality of education will be improved and it will be beneficial for the development of our country in this context.

Share-IT: A Sharing Platform for a Smart Campus

Abstract: In a university campus, it is often the case that students forget their important items, such as calculators, laptops or laptop chargers, on an exam day. Students need to borrow such items, but they do not know whom to borrow from. Buying a new calculator, or a laptop charger is expensive, considering that they are in need for only a couple of hours. Hence, the team proposes to develop ‘Share-IT’–a sharing platform for a smart campus that matches borrowers’ requests to available items by lenders. This paper discusses the developed Share-IT app, its functional and non-functional requirements, its underlying hardware and software components, and the entire development process, including system architecture, data model and software quality assurance tests and results. While the Share-IT prototype has been demonstrated at a university campus in Thailand, the software development process and method as reported in this paper can be implemented in other smart campus elsewhere.

Abstract: The present study analyzes the use of computer and mobile phone by university students, identifying their benefits and academic application. It is applied a non-probabilistic sample of 469 subjects in 10 universities, 5 in Spain and 5 in Ibero-American countries. We have employed a descriptive and factorial analysis. We concluded that there is a more significant presence of the laptop in the study and academic tasks, while the mobile phone is more present in communication and entertainment. The laptop has more presence in the instructive, informative, collaborative and illustrative functions, and in learning activities. The mobile phone performs better in terms of entertainment and communication functions. In any case, the benefits and satisfaction in using both devices are clear. This reality postulates teacher towards a new teaching methodology, including the preparation of resources to be used online.

Real-time Screen Sharing Using Web Socket for Presenting Without Projector

Abstract: The presentation is generally done using a laptop device or Personal Computer (PC) connected to a projector. Participants see a presentation slide show on a particular screen or white painted the wall. However, sometimes, problems occur when the projectors' equipment is not available to the presentation process does not run optimally. Other problems such as projector damage or dead pixel conditions and rainbow effects on the projector often interfere with the display permanently. A presentation without using a projector is one solution to overcome problems that have been proposed in previous research. However, there is still a particular server that is used by presenters and PCs to access those used by clients. The solution to overcome this problem, in this study, will be developed a system that can carry out the activity of sharing presentation between presenter and audience without using a projector. The presenter only requires an ordinary laptop or PC connected to a wireless network. Participants as clients can access the presentation display via a smartphone that is connected to the same wireless network as the server. The system built consists of two main applications: Screen Sharing Server and Screen Sharing Client, which allows sharing of views by implementing a socket web on its data communication model. Test results with 20 smartphone audiences can see the presentation results from the presenter's laptop. The presentation was successfully carried out with the concept of screen sharing in real-time without using additional projectors and computers, no need for cables and without the need for an internet connection.

Lightweight alternative tech: a study of Chromebooks in the academic library classroom

Abstract: The purpose of this paper is to evaluate Chromebooks as an alternative to the traditional computer laboratory for library instruction in an academic environment. The results of this study could help inform the creation of a mobile instruction lab that students and librarians quickly construct inside any classroom with minimal effort and no software to manage.,An online survey was distributed to student participants. The survey contained two demographic questions followed by seven user experience questions related to the in-classroom use of Chromebooks; most questions were quantitative in nature.,The majority of respondents (84 percent) strongly or somewhat agreed that Chromebooks were easy to use, and 15 percent of the respondents reported some difficulty accessing the university’s Wi-Fi system while using the devices.,This introductory study was limited to a survey population primarily comprised of lower-level undergraduate students in their first two years of study. Additionally, Chromebooks were not tested in an educational environment using G Suite for Education, which could increase the opportunities for use in an academic setting.,The study’s findings, combined with the portability and long battery life of Chromebooks, make them a candidate for a mobile instruction lab.,This research seeks to explore the viability of Chromebooks as an affordable and easy to manage alternative to wired instruction rooms, using a light laptop technology that is becoming increasingly familiar to college students.

Hygienic evaluation of the font design of electronic texts presented on a laptop

Abstract: Introduction. Currently, in connection with the large-scale introduction of the electronic educational resource in the educational process, it is especially relevant to search for optimal characteristics of presenting information on screens, taking into account the specifics of the electronic devices and age-related physiological features of the users’ visual system. The aim of the study was a physiological hygienic assessment of the impact of the font design of e-texts, presented on a laptop, on the psychophysiological state of students in grades 10-11. Material and methods. Psychophysiological testing of 43 schoolchildren in grades 10-11 without pathology of the vision organ was carried out on the NS-Psychotest complex, including the method of critical flicker fusion frequency to assess the state of the central part of the visual analyzer and the response to a moving object to determine the degree of the balance in nervous processes. The influence of reading illogical texts typed by a school headset was studied with a font size of 14, 12 and 10 points and a one-time reading of 200, 400 and 600 characters. Laptop Lenovo IdeaPad 720S-15 was used for the presentation of information. Results. High-grade schoolchildren were established to have the initial fatigue both of the visual analyzer and the nervous system as a whole. Boys showed better indices of the critical flicker fusion frequency than girls. Most schoolchildren had a balanced type of the inhibition and excitement processes. Methods of presenting information in electronic textbooks were shown to affect the psychophysiological state of high schoolchildren and may carry risks to their health. The hygienically rational design of electronic educational texts promotes the optimization of the psycho-functional state of the high schoolchildren’s body. Conclusion. The obtained results allow substantiating hygienic requirements for the font design of e-learning publications at the third stage of education.

A laptop for every child? The impact of ICT on educational outcomes

Abstract: Classrooms all over the world are becoming increasingly technologically advanced. Many schools today provide a personal laptop or tablet to each pupil for use both in the classroom and at home. The intent of these 1:1 programs is that information and communication technology (ICT) should be extensively involved in the teaching of all subjects. We investigate how pupils who are given a personal laptop or tablet, rather than having more limited computer access, are affected in terms of educational performance. By surveying schools in 26 Swedish municipalities regarding the implementation of 1:1 programs and combining this information with administrative data, we estimate the impact on educational outcomes using a difference-in-differences design. We find no significant impact on standardized tests in mathematics or language on average, nor do we find an impact on the probability of being admitted to upper secondary school or the students’ choice of educational track. However, our results indicate that 1:1 initiatives may increase inequality in education by worsening math skills and decreasing enrollment in college-preparatory programs in upper secondary school among students with lower educated parents.

Systems and methods for web-based communications consolidation

Abstract: Systems and methods for providing online access to multiple mobile station international subscriber directory numbers (MSISDNs), or mobile numbers, with compatible internet-connected user equipment (UEs). The system can include a web portal through which users can send and receive voice calls, video calls, text messages, e-mails, and other communications via multiple authorized mobile numbers. The system can include a graphical user interface (GUI) to enable users to select a mobile number to place a call or send a text, for example, with the call or text appearing to be sent from the mobile number. The system can also route incoming calls and texts to both the UE associated with the mobile number and the web portal. Thus, an incoming call, for example, can ring on both the UE and a tablet or laptop computer substantially simultaneously.
