In the paper we have studied differing kinds of security risks concerned in mobile devices and mobile applications and regarding varied defensive mechanism to stop these security risk in mobile devices.

Developing an Optical Measuring System for Hole Saw Caps

This paper developed a set of size detection systems with a computer vision method based on the accuracy requirements of the hole saw caps to meet the needs of the accuracy detection machine. The results allow manufacturers to build a digitalized hole saw cap detection system at a low cost. We have designed a measurement system for the hole saw caps with the computer vision method to measure the dimensions of the hole saw caps. However, a valid measurement value of the hole saw caps must be positioned symmetrically. However, in fact, when the measurement system is positioned accurately asymmetrically, it will cause a problem in the measurement data. Therefore, the dark box environment made of a light source and the back plate of the hole saw caps material and two cameras are employed to observe the hole saw caps from both above and the side views. Then, personal desktop computers calculate the size of the hole saw caps based on the camera screen vision with a Python program. The results of the proposed methodology are obtained by measuring 10 workpieces of different sizes, and all the errors within a range of 2 pixels (pixel, px) met the detection standards. Therefore, the developed hole saw cap detection system is in line with expectations.

OmniCrawl: Comprehensive Measurement of Web Tracking With Real Desktop and Mobile Browsers

Over half of all visits to websites now take place in a mobile browser, yet the majority of web privacy studies take the vantage point of desktop browsers, use emulated mobile browsers, or focus on just a single mobile browser instead. In this paper, we present a comprehensive web-tracking measurement study on mobile browsers and privacy-focused mobile browsers. Our study leverages a new web measurement infrastructure, OmniCrawl, which we develop to drive browsers on desktop computers and smartphones located on two continents. We capture web tracking measurements using 42 different non-emulated browsers simultaneously. We find that the third-party advertising and tracking ecosystem of mobile browsers is more similar to that of desktop browsers than previous findings suggested. We study privacy-focused browsers and find their protections differ significantly and in general are less for lower-ranked sites. Our findings also show that common methodological choices made by web measurement studies, such as the use of emulated mobile browsers and Selenium, can lead to website behavior that deviates from what actual users experience.

PERANCANGAN WEB RESPONSIVE UNTUK SISTEM INFORMASI OBAT-OBATAN

A good information system must not only be neat, effective, and resilient, but also must be user friendly and up to date. In a sense, it is able to be applied to various types of electronic devices, easily accessible at any whereand time (real time), and can be modified according to user needs in a relatively easy and simple way. Information systems are now needed by various parties, especially in the field of administration and sale of medicines for Cut Nyak Dhien Hospital. During this time, recording in books has been very ineffective and caused many problems, such as difficulty in accessing old data, asa well as the information obtained was not real time. To solve it, this research raises the theme of the appropriate information system design for the hospital concerned, by utilizing CSS Bootstrap framework and research methodology for web development, namely Web Development Life Cycle. This research resulted in a responsive system by providing easy access through desktop computers, tablets, and smartphones so that it would help the hospital in the data processing process in real time.

Virtual look around: comparing presence, cybersickness and usability for virtual tours across different devices

Virtual Reality has become readily available in the last few years through different devices, from desktop computers to head­-mounted displays (HMD). Also, virtual tours became popular with 360º panoramic photographs and video clips on online social media, so people could visit remote locations without being exposed to crowded transportation or long travels. Also, virtual tours demonstrate considerable potential as a form of escapism and even for remote teaching. Since we lack studies that evaluate the User Experience (UX) in virtual tours on different devices, this article aims to compare aspects of the User Experience (regarding sense of presence, cybersickness, and usability) in a virtual tour website developed in WebXR across different devices. To achieve our objective, we developed a virtual tour based on 360º pictures using WebXR API and React 360 framework and conducted an experiment with 41 undergraduate students using four different devices: a laptop computer, a smartphone, a Google Cardboard headset, and a Samsung Gear VR HMD. We evaluated users’ perceptions by adapting and translating the Suitability Evaluation Questionnaire (SEQ) and users’ performance by measuring the time to fulfill a set of tasks. The main findings from this study include that (i) the overall self-­reported experience using Google Cardboard is worse than using other devices, (ii) the users’ performance is quite similar between the platforms, (iii) there is evidence of unexpected cybersickness symptoms in tests with the smartphone, and (iv) the development of a plausible hypothesis concerning low usability having an effect upon the sense of presence. Additional contributions of our research are the adaptation, translation into Portuguese, psychometric analysis, and revised scoring procedures of the SEQ.

Health-related consequences of the type and utilization rates of electronic devices by college students

Background College students are leading an evolution of device use both in the type of device and the frequency of use. They have transitioned from desktop stations to laptops, tablets, and especially smartphones and use them throughout the day and into the night. Methods Using a 35-min online survey, we sought to understand how technology daily usage patterns, device types, and postures affect pain and discomfort to understand how knowledge of that pain might help students avoid it. Data were analyzed from 515 students (69.5% male) who completed an internet-delivered survey (81.3% response rate). Results Participants ranked smartphones as their most frequently used technology (64.0%), followed by laptops and tablets (both 53.2%), and desktop computers (46.4%). Time spent using smartphones averaged over 4.4 h per day. When using their devices, students were more likely to adopt non-traditional workplace postures as they used these devices primarily on the couch or at a chair with no desk. Conclusion Recent trends in wireless academic access points along with the portability of small handheld devices, have made smartphones the most common link to educational materials despite having the least favorable control and display scenario from an ergonomic perspective. Further, the potential impact of transitions in work environments due to COVID-19 may further exacerbate ergonomic issues among millions highlighting the need for such work to be carried out.

Novel Air-Cooled Thermosyphon Cooling System for Desktop Computers

The trade-off between efficient cooling and low power consumption is a goal that has always been very desirable in electronics cooling, especially nowadays that power densities of processing units are increasing. Conventional cooling solutions do not have the necessary cooling capacities for these power densities or require significant power consumption. In this study, a novel air-cooled thermosyphon cooling system for desktop computers is presented and experimentally tested. The thermosyphon comprises a vertical micro-channel cold plate as the evaporator and a horizontal air-cooled multiport coil as the condenser. The thermosyphon has a total height of 12 cm and operates with a fan speed of 1700 RPM. The working fluid selected for the thermosyphon loop is R1234ze(E), chosen for its advantageous thermophysical properties and nearly zero-GWP (Global Warming Potential). The test results presented in this paper aim to analyze thermosyphon’s thermal and hydraulic performance by studying the trends of thermal resistance and mass flow rate as a function of different operating conditions. The maximum heat rejection under safe conditions is 250 W, corresponding to a heat flux of about 18 W/cm2.

The Impact of the Pandemic (COVID-19) on Globalization – The Perspective of Electronic Commerce

Purpose: The objective of this article is to examine the impact of e-commerce and m-commerce on broadly perceived globalization factors before and during the COVID-19 pandemic in the opinion of customers. Design/methodology/approach: The CAWI method was used with the participation of individual, active internet users from both periods. The differences between the results were analyzed using the distance indices: city distance and Euclidean distance. The data from March 2020 (before the pandemic) and from December 2020 (during the pandemic) were used as the basis for comparisons. Findings: The findings point to increasing diversification in the product/services range and the growing number of goods and services purchased abroad. There occur much smaller differences with regard to infrastructure factors which have a direct influence on foreign e-commerce. Also, in the respondents’ opinions, greater popularity and more frequent use of international commerce solutions during the pandemic is treated as a factor which supports the development of globalization. The main observed changes during the COVID-19 pandemic are infrastructure changes (staying at home, remote learning, remote work, etc.) and an extend and standardized approach to e-commerce. The second equally important effect is the shift from desktop computers to mobile devices. Research limitations/implications: The limitation resulted from the research sample obtained in the academic environment. Students are a group supporting the globalization processes, where e-business solutions are widely used, but their purchases of products/services, including foreign goods, are often limited due to lack of funds. Originality/value: The original value of the article is the identification and specification of the main factors supporting globalization in Poland during the COVID-19 pandemic from the point of view of electronic commerce.
