A New Generalized Θ-Inverse vs. Moore-Penrose Structure: A Comparative Control-Oriented Practical Investigation

A new non-unique <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\Theta $ </tex-math></inline-formula> -inverse of non-square polynomial matrices is presented in this paper. It is shown that the above inverse specializes to the unique Moore-Penrose one under several specific assumptions. Due to the existence of some degrees of freedom, the <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\Theta $ </tex-math></inline-formula> -inverse outperforms the Moore-Penrose inverse in various inverse-related problems covering the multivariable control theory. In many scenarios the former inverse can stabilize a closed-loop control plant being unstable by application of the Moore-Penrose formula. Practical and theoretical simulation examples confirm the correctness of the proposed method.
Education in Times of the Pandemic COVID 19

In this reflective essay, I want to show the situation that I experienced in the last semester of my career, which was the investigative pedagogical final practicum at the Universidad Pedagógica y Tecnológica de Colombia. I started developing this last stage in the “Escuela Normal Superior Santiago de Tunja”. Then, I had to change the institution, and I finished my practice in the “Institución Educativa Libertador Simón Bolívar”. In this process, the COVID 19 pandemic was expanding in almost every country, and the world stopped the normal development of activities, which included the academic institutions. For that reason, I decided to reflect about education around the world and some of the challenges that are always present. Also, I wanted to talk about the new difficulties related to the virus and the ways teaching could implement technological devices and internet connection. Finally, I write some of the implications that I consider important in these difficult times in which education will not stop.
Using Platform Models for a Guided Explanatory Diagnosis Generation for Mobile Robots

Plan execution on a mobile robot is inherently error-prone, as the robot needs to act in a physical world which can never be completely controlled by the robot. If an error occurs during execution, the true world state is unknown, as a failure may have unobservable consequences. One approach to deal with such failures is diagnosis, where the true world state is determined by identifying a set of faults based on sensed observations. In this paper, we present a novel approach to explanatory diagnosis, based on the assumption that most failures occur due to some robot hardware failure. We model the robot platform components with state machines and formulate action variants for the robots' actions, modelling different fault modes. We apply diagnosis as planning with a top-k planning approach to determine possible diagnosis candidates and then use active diagnosis to find out which of those candidates is the true diagnosis. Finally, based on the platform model, we recover from the occurred failure such that the robot can continue to operate. We evaluate our approach in a logistics robots scenario by comparing it to having no diagnosis and diagnosis without platform models, showing a significant improvement to both alternatives.
Marketing Strategy Using Frequent Pattern Growth

The biggest problem faced by printing companies during the Covid-19 pandemic was that the number of orders was unstable and tends to decrease, which had the potential to harm the company. Therefore, various appropriate marketing strategies were needed so that the number of product orders was relatively stable and even increases. The impact was that the company could survive and continued to grow. This study aimed to assist company managers in developing appropriate marketing strategies based on association rules generated from one of the data mining methods, namely the Frequent Pattern Growth (FP-Growth) method. The case study of this research was a printing company where there was no similar research that used a printing company's dataset. This study produced nine association rules that meet a minimum of 25% support and a minimum of 60% confidence, but only two association rules that had a high positive correlation, namely for a custom paper bag and banner products. Therefore, several marketing strategies were suggested that could be used as guidelines for companies in managing sales packages and giving special discounts on a product. The results of this study are expected to trigger an increase in the number of product orders because this study tried to find the right product for consumers and did not try to find the right consumers for a product.
Cryptodiagnosis of “Kryptos K4”

The sculpture "Kryptos" at the Central Intelligence Agency in Langley, Virginia, contains four encrypted passages.The last, known as "K4" and consisting of 97 letters, remains unsolved.In this work, we look at unusual statistical properties of the K4 ciphertext, together with the known plaintext, using Monte Carlo sampling to perform permutation testing.This provides evidence strongly indicating a definite "one-to-one" relationship between corresponding plaintext and ciphertext letters.It also points toward a possible encryption method which could account for most or all of the observed properties.This is the "Gromark" cipher invented by Hall (1969Hall ( , 1975) ) and analyzed by Blackman (1989).

SMS Goes Nuclear: Fortifying SMS-Based MFA in Online Account Ecosystem

With the rapid growth of online services, the number of online accounts proliferates. The security of a single user account no longer depends merely on its own service provider but also the accounts on other service platforms (We refer to this online account environment as Online Account Ecosystem). In this paper, we first uncover the vulnerability of Online Account Ecosystem, which stems from the defective multi-factor authentication (MFA), specifically the ones with SMS-based verification, and dependencies among accounts on different platforms. We propose Chain Reaction Attack that exploits the weakest point in Online Account Ecosystem and can ultimately compromise the most secure platform. Furthermore, we design and implement ActFort, a systematic approach to detect the vulnerability of Online Account Ecosystem by analyzing the authentication credential factors and sensitive personal information as well as evaluating the dependency relationships among online accounts. We evaluate our system on hundreds of representative online services listed in Alexa in diversified fields. Based on the analysis from ActFort, we provide several pragmatic insights into the current Online Account Ecosystem and propose several feasible countermeasures including the online account exposed information protection mechanism and the built-in authentication to fortify the security of Online Account Ecosystem.
Formation of a Culture of Social Digital Responsibility in the Context of Educational Inclusion

The article is aimed at describing the formation of a culture of social digital responsibility, taking into account educational inclusion. Statistics and studies on the quantity and quality of personal time spent by the population of the planet on the Internet are analyzed. Analyzing and systematizing the work of various NGOs, scientists and specialists, digital citizenship rules are formed; the issues of digital responsibility, the formation of culture, inclusion in education are considered. In addition, the features that should be taken into account during inclusion in education are defined. The types of personality temperament are also considered; the relationship between the types of tasks for students and the peculiarities of their temperament, world perception and preferences is determined. The means, rules and principles of the culture of social digital responsibility and digital instruments that should be used in educational institutions in conditions of inclusion have been formed, because they help in attracting as many students as possible to the learning process and in easier assimilation of information. It is determined that the modern culture of social digital responsibility in the context of educational inclusion should contain not only the rules of conduct during communication or the use of the world wide web and the means of involving all students in the educational process, but also the basic principles of activity. The main problems of formation of a culture of social digital responsibility in the context of educational inclusion are also specified. The problem of forming a culture of social digital responsibility in the context of educational inclusion contains two components: the problem of digital behavior culture (students/teachers), and the problem of digital learning. The latter outlines the need to create conditions for the conscious perception of educational information by students/pupils, to attract their maximum number to the educational process through the use of effective digital instruments, the development of the authors’ own educational methodological approaches for any form of education (remote/full-time)
Adopting task technology fit model on e-voting technology

&lt;span&gt;E&lt;/span&gt;&lt;span&gt;-voting is a tool to support the voting process starting from recording, voting, and counting votes using electronic devices. E-voting promises a faster voting process, reduced budget costs, lost votes due to damaged ballot papers during the voting process, and others. E-voting is also used in high school student council elections. Young people are more computer literate (computer literacy) and interested in using new technology (e-voting) than adults and older people. This study aims to determine the suitability of e-voting in the SMA OSIS election to the user's task support using the task-technology fit (TTF) model. The data analysis used is multiple regression analysis. This analysis is used to determine the effect of the independent variables on the dependent variable with a significance level of 5%.

Superconducting microbridge single photon detectors with improved temporal response

We report a single photon detector based on NbTiN microbridges, suitable for operation within telecommunication wavelengths. We observed an excellent signal-to-noise ratio of the readout signal while the corresponding jitter contributed by electrical noise was measured to be less than 10 ps. Routing the current through a parallel electrical connection to set the microbridge back to the superconducting state after photon absorption enabled us to overcome the hysteresis of the state transition. Our approach combines facile fabrication of fast microscale detectors with efficient current redistribution mechanism, enabling prospective applications in quantum photonics which requires accurate estimation of photon arrival events.
Dampak Pandemi terhadap Pembelajaran di Era Pandemic Covid-19

As a result of the pandemic that started in Wuhan, China and spread to all corners of the world including Indonesia. Impact felt by residents the world including Indonesia is very complicated. The number of employees who have been laid off has led to a decline in the economy which has affected the education sector. Physical distancing that is applied has many impacts on people's lives. Markets, malls, offices and even schools are closed. All activities are carried out online, even for schools, which are usually face-to-face, are now held virtually. The number of complaints that arise because of this pandemic starts from complaints about assignments because teachers only give assignments without explaining first, on the other hand students are told to learn and maintain health. We know that the large number of tasks given by the teacher indirectly affects the mental health of students. Another problem is the single tuition fee (UKT) which sometimes gets stuck because parents are laid off creates new problems and often this makes students drop out of school / college. In this case the role of government is needed. The government is expected to go directly to the field to review the conditions of the affected communities. Not only entrusting it to subordinates or officials. Especially in the field of education because the education of the nation's children is the main hope of the Indonesian nation. This research uses the literary method and it is hoped that this research can have an influence on education in Indonesia and education can get great attention by the government.
Efficient Multi-linear Key Pairing Cryptosystem for Reliable Cloud-based Service Provisioning

Cloud computing has gained rapid growth in the development of different fields of science and engineering. However, due to the distributed nature of cloud computing, session key generation and establishment is the pressing issue. Session key management plays the utmost important role in the secure exchange of sensitive login credentials and transaction information. Moreover, conventional session key management mechanisms are inadequate and cannot be directly adopted in cloud-based environments. Hence, session key management is very much solely needed solution for reliable cloud-based service provisioning. In mutual authentication, bi-linear key pairing cryptosystem plays a critical role to generate and establish a session key. The existing mutual authentication schemes fail to support true mutual authentication in cloud-based environments as they are vulnerable to secret key leakage, perfect forward secrecy, and untraceability. To mitigate the effect of these attacks, this research develops an efficient multi-linear key pairing cryptosystem. In this cryptosystem, challenge-response messages are used for generating and establishing a one-time shared session key. Furthermore, the performance analysis of the proposed cryptosystem depicts a significant reduction of computation cost, authentication accuracy rates, and resistance to the aforementioned attacks.
