A New Methodology for the Development of Secure and Paranoid Operating Systems

Abstract It has recently been discovered that large companies and nations “observe” their customers and citizens, disregarding any remaining moral and technological lines, being able to listen to telephone conversations and monitoring communications, through powerful monitoring and surveillance programs. Elsewhere on the planet, nations in turmoil or wrapped in a cloak of censorship persecute their citizens, controlling them by denying them access to the free Web without the threat of repercussions that threatens their dignity. To support the present research, an analysis of platforms that allow anonymous and secure browsing and a study of technologies and programs with potential privacy breach and computer intrusion were performed. The main objective of this work was to analyse the computer monitoring and surveillance technologies, identifying the available tools, trying to find potential solutions, developing and providing a methodology that enhances any desktop, server or mobile operating system, with characteristics that combat the exposed in this summary.

Adaptiveness of Traditional Judicial Systems to Digital Forms of Evidence

“Digital India” scheme announced by current administration initially had many detractors. But with its finger on the correct pulse of Young, Emergent India, much facilitations were provided with the sole aim to bridge technology with the masses. Hence today smart phones, laptops and computers have become house-hold names even in previously inaccessible areas. But on the down-side we also see a severe increase in crimes committed using computers and internet. Technology is an ever-changing phenomenon. It keeps changing, updating and even reviving itself. Crime has parallelly evolved with the evolution of newer technologies and high-end equipments and tool. With the metamorphosis of criminal-activities from physical world to digital realm, a perpetrator can easily plan, execute and accomplish a crime without being actually physically present at the site of crime, thus making it difficult for investigators, law enforcement officials and traditional legal systems completely depending on physical evidence to recognize the real culprit or to determine guilt and decide the degree of punishment. Using a desktop system or a laptop or even a Smartphone, the criminal can exploit the power of internet, Bluetooth ,Wi-Fi technologies , 4G data-transfer speeds and web-servers to execute an unlawful act sitting miles away from the place where the actual crime happens thereafter leaving absolutely no physical trail of the execution of the offence. Under these conditions, it becomes imperative to utilize digital footprints as they are the only way to determine the factuality of execution of an unlawful act and to identify the real culprit. As the guiding principle of IPC goes "Innocent until proven guilty", digital footprints have to be given their rightful due in the existing Judicial system to help in confirming execution of an unlawful act, detecting the actual culprit and determining the amount of punishment. This paper attempts to highlight the significance of digital footprints and usage of the same by the existing Justice Systems to corroborate, attest and substantiate the execution of an unlawful act.

The Feasibility and Utility of a Mobile-Based Eye Movement Recording Application: A Randomized Trial

Objectives This study was performed to assess the efficacy and feasibility of mobile application-based Frenzel tests in dizziness clinics. Methods We performed an investigator-initiated, blinded-outcome assessor, parallel, randomized controlled crossover trial at Chungnam National University Hospital between August 2019 and October 2019. Certified medical staffs were randomly assigned to the intervention group (i.e., a mobile application-based Frenzel glass system, n=15) or the observation group (i.e., a conventional desktop-based Frenzel glass system, n=15); the groups applied the respective systems for the preparation of eye movement recording and switched systems. The primary outcome was the elapsed time in seconds it took the participants to prepare the system for eye recording simulation. The secondary outcomes were perceived stress and satisfaction scores after completion of the operation, as measured by a questionnaire using 10-point Likert scales. Results The mean time of machine preparation for eye recording simulation was reduced by 50% in the mobile application group compared to the desktop group in both study periods (38.0±7.1 sec vs. 76.0±8.7 sec). We detected no carryover effect. Participants also reported lower stress while using application than while using the desktop system (2.3±1.3 vs. 4.6±2.4; p＜0.001). The application obtained a mean overall satisfaction score of 9.2 out of 10. Conclusions The implementation of an eye movement recording application in a dizziness examination was well adopted by users and decreased the time and stress related to machine operation.

Green energy from working surfaces: a contact electrification–enabled data theft protection and monitoring smart table

Data theft from the desktop system using devices capable of storing data is a serious problem that causes great harm to an individual or a company. It is essential to excogitate a way to reduce the problem. The triboelectric nanogenerator (TENG), recently introduced as a light-weight, easy-to-design energy harvester, works on the coupling of electromagnetic induction and contact electrification. In this work, a TENG is used to incorporate a smart feature in the table which triggers an alarm if an intruder is using the desk. The TENG works in the single-electrode contact-separation mode and in the sliding mode. The Kapton backed by aluminum is used as active triboelectric layers while the material on apparels or hand skin acts as opposite triboelectric material. The device is systematically studied for its electrical performance using materials such as jeans, cotton, paper, etc. The device gives the highest output voltage and current of ~200 V and 2.2 μA in case of paper. Finally, a smart table is demonstrated using the as-fabricated TENG coupled with the Arduino board which triggers an alarm if a person is accessing the desk. This work can extend the application of the TENG for the development of smart furnitures.

Development brushless direct current electric motor of the Pilger mill drive for the technology of seamless pipes manufacturing based on the magnetic system with claw-poles

Currently, metallurgical industry contains a large number of morally and physically outdated electrical equipment that requires modernization. It requires a large capital expenditure to replace it. For this reason, it is slow to implement, long-term use for the purpose of payback, and slow to withdraw from manufacturing. In this regard, the new equipment must be innovative and in many respects ahead of the existing level of development of the industry. The article suggests such a solution. To replace the existing collector motor of the pilger mill drive for the manufacturing of seamless pipes, which has been operating since 1928 and is in a critical condition, a large-sized low-speed brushless motor with a large built-in inertial mass is proposed, which has a permanent magnet magnetic system and claw-poles. Such a technical solution for drives of this class has not been used in the world. The motor eliminates the existing 120-ton flywheel, improves reliability due to contactless current supply, and reduces operating costs by eliminating excitation losses. The motor design allows its Assembly without additional tooling, which is very important for large motors with permanent magnets. To develop a unique motor, a design system consisting of a synthesis subsystem and an analysis subsystem was created. The synthesis subsystem implements multi-level single-criteria optimization. As a result of its operation, the optimal geometry is determined based on the selected criterion. The analysis system confirms the calculation reliability using simplified optimization methods and finally removes technical risks before manufacturing an industrial design. It is based on the well-developed Ansys Electronics Desktop and Ansys Icepak systems for CAE electric machines. The analysis has several stages, which includes electromagnetic and thermal analysis. It is based on the well-developed for CAE systems electric machines Ansys Electronics Desktop and Ansys Icepak. The analysis has several stages, which includes electromagnetic and thermal analysis. The effectiveness of the design system was tested on a real project that was performed for the Chelyabinsk rolling mill. This approach is recommended for the design of other similar types of brushless direct current drive.

Capabilities and Limitations of Using Desktop 3-D Printers in the Laser Sintering Process

Almost one-third of the revenues of the Additive Manufacturing (AM) machines market is generated by desktop systems. A new category of such devices are Laser Sintering (LS) machines, in which we can find a few representatives of this group. A growing interest in the use of desktop AM solutions in research and industry is visible, and therefore an evaluation of its capabilities and limitations is desirable. The presented paper focuses on comparing desktop (Sintratec S1; Sinterit Lisa) and industrial (Formiga P110) LS systems. The properties of raw materials were characterized by Scanning Electron Microscopy (SEM) and Differential Scanning Calorimetry (DSC), as well as by determining the Particle Size Distribution (PSD) and static and dynamic flowability of powder. Laser Sintering commercial sets were characterized by their mechanical properties (tensile strength), surface quality (roughness), as well as by their accuracy and porosity (computed tomography). The conducted test showed significant differences, especially in the case of material properties and manufacturing repeatability. The found differences between desktop and industrial LS systems suggest that the use of a low-budget LS system, especially for the research and production of end-use parts, has to take into account its limitations.

An Efficient BGV-type Encryption Scheme for IoT Systems

Internet of Thing (IoT) systems usually have less storage and computing power than desktop systems. This paper proposes an efficient BGV-type homomorphic encryption scheme in order fit for secure computing on IoT system. Our scheme reduces the storage space for switch keys and ciphertext evaluation time comparing with previous BGV-type cryptosystems. Specifically, the switch key in homomorphic computations can be a constant but no longer one for each level. Moreover, the product of two ciphertexts can be at the same sublayer as them and the multiplication operations can be repeated between two sublayers. As a result, the multiplication times will not be limited by L in an L-level circuit and, thus, the ciphertext evaluation time will decrease significantly. We implement the scheme with the C language. The performance test shows that the efficiency of the improved scheme is better than Helib in same configurations.

Sustainable disturbance crosstalk mitigation in deeply scaled phase-change memory

While Phase Change Memory (PCM) is gaining popularity in next generation systems compared to conventional DRAM and Flash, write disturbance due to crosstalk remains a significant challenge to PCM performance and reliability. To address this concern we propose a multi-tiered compression (MTC) technique combined with novel encoding that can decrease the probability of write disturbance. MTC compresses a high proportion (>94%) of cachelines by a small predictable amount (e.g., 40- or 56-bits of a 512-bit block) while maintaining data similarity vital for optimizing PCM writes. By detecting data patterns prone to crosstalk, we use encoding, correction pointers, and a hybrid approach to reduce the instances of write disturbance. We use MTC reclaimed bits to store the encoding. Thus, our approach requires only five additional auxiliary bits per 512-bit cacheline, minimizing the embodied energy (fabrication) overhead to mitigate write disturbance. Additionally, through a multi-objective optimization, dramatic endurance improvements are possible while maintaining nearly all write disturbance improvement.Our technique improves performance, endurance and write energy by 47%, 42% and 36% versus the state-of-the-art with nominal (circa 1%) increases to embodied energy. When considering the full life-cycle impact, the additional area of our MTC with encoding approach is mitigated by the use-phase benefits within 60 days for a high performance system and in less than four years of use for a desktop system. In nearly all studied scenarios, the improved lifetime provided by our MTC and encoding approach easily recoups the required additional upfront manufacturing energy.

Evaluation of porcine semen quality by portable and desktop CASA systems - Short communication.

When using artificial insemination in porcine reproduction, one of the most important requirements is the suitable quality of semen regarding its total motility (TM) and progressive motility (PM). Computer-assisted sperm analysis (CASA) is an appropriate method to analyse the quality of semen. Recently a portable instrument has been developed to help specialists in their everyday field work. In our study, semen quality was measured simultaneously by the portable device (Ongo) and a laboratory CASA system (Microptic) to compare TM and PM values obtained by these appliances at a concentration of 50 × 106 spermatozoa/mL. Agreement between measurements was evaluated with a Bland-Altman plot. Strong correlation was found between the investigated instruments for all the three parameters, i.e. sperm concentration, TM and PM. However, a few measurements fell outside the defined range of acceptance.

Visual-inertial teach and repeat

Teach and Repeat (T&R) refers to the technology that allows a robot to autonomously follow a previously traversed route, in a natural scene and using only its onboard sensors. In this paper we present a Visual-Inertial Teach and Repeat (VI-T&R) algorithm that uses stereo and inertial data and targets Unmanned Aerial Vehicles with limited on-board computational resources. We propose a tightly-coupled relative formulation of the visual-inertial constraints that is tailored to the T&R application. In order to achieve real-time operation on limited hardware, we reduce the problem to motion-only visual-inertial Bundle Adjustment. In the repeat stage, we detail how to generate a trajectory and smoothly follow it with a constantly changing relative frame. The proposed method is validated in simulated environments, using real sensor data from the public EuRoC dataset, and using our own robotic setup and closed-loop control. Our experimental results demonstrate high accuracy and real-time performance both on a standard desktop system and on a low-cost Odroid X-U4 embedded computer.

A Virtual Reality Simulation of Drug Users' Everyday Life: The Effect of Supported Sensorimotor Contingencies on Empathy.

Perspective taking techniques have been used to transport people into imaginary situations and the lives of others. Virtual Reality provides an immersive way to virtually experience the lives of stigmatized by society members. Through the support of sensorimotor contingencies, people can use natural movements to view and interact with the virtual world around them. In this study, we compared a perspective-taking immersive Virtual Reality system which supports a number of sensorimotor contingencies (SC group) with a perspective-taking desktop system of the same application but without support of any sensorimotor contingencies (NSC group), to investigate the effect of the supported sensorimotor contingencies in promoting empathy and positive attitudes toward drug users. Results demonstrate a strong correlation between closeness to the drug user and empathy in the SC group. In both groups there were a within group significant change in their reported attitudes before and after their exposure. Finally, participants in the SC condition reported significantly higher levels of Place Illusion (PI), body ownership, agency and plausibility of people. Further research is needed to investigate how sensorimotor contingencies can be exploited to the fullest to be used as an effective method to induce empathy and change attitudes toward stigmatized by society people.

Batch Electrocoagulation Treatment of Peat Water in Sarawak with Galvanized Iron Electrodes

Peat water is an abundant water resource in Sarawak where some of the coastal areas in Sarawak still utilize peat water for domestic usage. Peat water contains natural organic matters especially humic substances which include humic acids. Humic acids contribute to the brown color of peat water and can cause diseases such as stomach cancer, blackfoot disease and etc. if consumed by human. Electrocoagulation is an alternative to conventional water treatment methods which have the advantages of being environmental friendly, minimal sludge production and no addition of chemical substances. The aims of this study are to fabricate a desktop scale electrocoagulation system with galvanised iron electrodes and to investigate the effects of the operating parameters such as inter-electrode distance, applied current density, number of electrodes, and treatment time on peat water in the system. The performance of batch electrocoagulation system in term of their removal efficiency of several parameters such as total organic carbon (TOC), chemical oxygen demand (COD), color and turbidity are evaluated. Through experimental tests conducted, this system successfully removes 98.44% of COD, 92.02% of TOC, 97.92% of turbidity and 99.91% of color by using galvanized iron as an electrode at current density of 25 A/m2in 30 minutes with 10 galvanized iron electrodes. Despite the fact that there is a small amount of iron ions and zinc ions remained in the treated peat water which are 0.001mg/l and 0.0442mg/l respectively, these concentrations are far below the standard limits imposed by Malaysia Ministry of Health (MOH). Generally, all the parameters studied meet the standard limit imposed by MOH except for total organic carbon. This is particularly due to the improper filtration system adopted in this study. The total operating costs for 252 in 30 minutes treatment time of 10 electrode plates is RM 8.75 per . Overall, the study have successfully designed a batch electrocoagulation system to treat peat water by using galvanized iron for domestic usage.

Comparison of ranking models to evaluate desktop 3D printers in a growing market

While additive manufacturing (AM), commonly known as 3D printing, has been in existence commercially for ∼30 years, desktop 3D printers are a relatively new and rapidly growing market segment. Both well-established AM companies and an increasing number of new enterprises are designing and retailing desktop systems of various sizes, capabilities, and prices. With the abundance of desktop systems now on the market, a consumer may benefit from determining which system best serves their needs. This research highlights differences amongst 45 desktop 3D printers and suggests a method by which to evaluate such differences. For this, a standard part consisting of various geometric features was designed and printed using each system. An updated version of a previously developed quantitative ranking model was utilized to rate the build precision of each system as well as other features, including build volume, size, cost, weight, and layer resolution. In addition, the research team observed part aesthetics and quantified mechanical properties. The criteria evaluated in this ranking model may be modified by each user, to extend this methodology to other desktop AM systems, including professional-grade machines. The results from the model presented in this research were compared with other commonly used ranking methods to help evaluate each technique. These included a simple ascending order rank based model adjusted for ties (1-best and 45-worst), a percentile value based model evaluating the factor contribution values presented in this paper; and the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) which evaluated separation measures from ideal and worst solutions. As expected, the comparisons demonstrated that each model had slightly different rankings as compared to the model presented in this paper, with some outliers. Consequently, it was observed that percentile value based models (such as one presented in this paper) provide rankings different from separation value based models (from ideal and worst solutions) such as TOPSIS.

A Multi-Tier Streaming Analytics Model of 0-Day Ransomware Detection Using Machine Learning

Desktop and portable platform-based information systems become the most tempting target of crypto and locker ransomware attacks during the last decades. Hence, researchers have developed anti-ransomware tools to assist the Windows platform at thwarting ransomware attacks, protecting the information, preserving the users’ privacy, and securing the inter-related information systems through the Internet. Furthermore, they utilized machine learning to devote useful anti-ransomware tools that detect sophisticated versions. However, such anti-ransomware tools remain sub-optimal in efficacy, partial to analyzing ransomware traits, inactive to learn significant and imbalanced data streams, limited to attributing the versions’ ancestor families, and indecisive about fusing the multi-descent versions. In this paper, we propose a hybrid machine learner model, which is a multi-tiered streaming analytics model that classifies various ransomware versions of 14 families by learning 24 static and dynamic traits. The proposed model classifies ransomware versions to their ancestor families numerally and fuses those of multi-descent families statistically. Thus, it classifies ransomware versions among 40K corpora of ransomware, malware, and good-ware versions through both semi-realistic and realistic environments. The supremacy of this ransomware streaming analytics model among competitive anti-ransomware technologies is proven experimentally and justified critically with the average of 97% classification accuracy, 2.4% mistake rate, and 0.34% miss rate under comparative and realistic test.

Landsat Images Classification Algorithm (LICA) to Automatically Extract Land Cover Information in Google Earth Engine Environment

Remote sensing has been recognized as the main technique to extract land cover/land use (LC/LU) data, required to address many environmental issues. Therefore, over the years, many approaches have been introduced and explored to optimize the resultant classification maps. Particularly, index-based methods have highlighted its efficiency and effectiveness in detecting LC/LU in a multitemporal and multisensors analysis perspective. Nevertheless, the developed indices are suitable to extract a specific class but not to completely classify the whole area. In this study, a new Landsat Images Classification Algorithm (LICA) is proposed to automatically detect land cover (LC) information using satellite open data provided by different Landsat missions in order to perform a multitemporal and multisensors analysis. All the steps of the proposed method were implemented within Google Earth Engine (GEE) to automatize the procedure, manage geospatial big data, and quickly extract land cover information. The algorithm was tested on the experimental site of Siponto, a historic municipality located in Apulia Region (Southern Italy) using 12 radiometrically and atmospherically corrected satellite images collected from Landsat archive (four images, one for each season, were selected from Landsat 5, 7, and 8, respectively). Those images were initially used to assess the performance of 82 traditional spectral indices. Since their classification accuracy and the number of identified LC categories were not satisfying, an analysis of the different spectral signatures existing in the study area was also performed, generating a new algorithm based on the sequential application of two new indices (SwirTirRed (STRed) index and SwiRed index). The former was based on the integration of shortwave infrared (SWIR), thermal infrared (TIR), and red bands, whereas the latter featured a combination of SWIR and red bands. The performance of LICA was preferable to those of conventional indices both in terms of accuracy and extracted classes number (water, dense and sparse vegetation, mining areas, built-up areas versus water, and dense and sparse vegetation). GEE platform allowed us to go beyond desktop system limitations, reducing acquisition and processing times for geospatial big data.

Remote desktop system in IoT and HTML 5-based virtual laboratory for HMI (Human Machine Interface) practicum and hydraulic simulation

A virtual laboratory is a facility that allows access to laboratory equipment from anywhere and anytime while connected to the internet. Remote desktop systems are the basis of the development of a virtual laboratory where users can access hardware connected to the lab computer from anywhere with the agreed time. The virtual laboratory can overcome the problem of the imbalance of the number of tools available in the lab with the number of students who will do the practicum, especially the PLC, HMI, and hydraulic simulation. For accessing the lab computer, this tool uses web-based HTML and VNC (Virtual Network Computing) techniques. On the server computer, the ThinVNC server is installed, and the user, password, and port are set. ThinVNC functions as a tool that makes it easy for users to access the lab because it merely provides a web browser that supports HTML 5 such as chrome, firefox, and edge without having to install any browser plugins and does not need to install RDP, so tablet or smartphone can access the lab. When it is connected, the user can access the available lab equipment and can see the results made because there are cameras that monitor the course of the practicum.
