Pendeteksian Bit Error Dalam Transmisi Data Dengan Menerapkan Cyclic Redudancy Check
Authors: Sirait Matias Julius Fika , Sinaga Sony Bahagia
Published: October 2021

The communication path that will physically connect the two technologies conceptually works together such as cables. A special feature of a channel that resembles a cable is where the bits will be forwarded in the same order along with the bits sent. Data link layers have specific functions, this function includes starting from providing interfaces for services that are good for the network layer. Communication flows often make mistakes, sometimes having limited data rates and experiencing propagation delays other than zero between when bits are sent when the bit is received. This limitation is an implication of the importance of the efficiency of data transfer. Delivery of information in the telecommunications world will often occur errors in the data to be sent. This error is caused by a disturbance at the physical level, which is a disruption of the transmission line media, such as interference with electromagnetic radiation, cross communication, lightning or noise disturbance. This interference causes the information received does not match the information sent. The Cyclical Redundancy Check method, or CRC, is a method for handling error detection, this method uses binary numbers. The CRC data detection model is sent perframe consisting of a long row of bits for each frame.

Host seed type and volatile compound abundance level mould host location and preference behaviours in Callosobruchus maculatus (Fabricius, 1775) (Coleoptera: Chrysomelidae)
Authors: Ahuchaogu Christopher Emeka , Ojiako Frank Onyemaobi
Published: October 2021

Dry seeds of cowpea, an important food, and cash crop to farmers, are heavily infested by Callosobruchus maculatus (Fabricius, 1775) during storage, causing huge economic loss. As a result, farmers spray pesticides on their harvest to control the pest attack with little consideration for the consequences of their actions. Due to health and environmental concerns associated with pesticide applications, farmers, marketers, and end-users are seeking alternative safer routes to handling this infestation problem. Thus, this study investigated the response of mated female C. maculatus to odour cues from different bean types using two-arm and four-arm olfactometers. The volatile organic compounds from the preferred beans (Borno brown and black-eyed beans-cultivars of Vigna unguiculata Walper, 1843 and adzuki bean – Vigna angularis (Willdenow) Ohwi & Ohashi, 1969), were analysed using gas chromatography-mass spectrometry (GCMS) techniques and headspace volatile organic compounds were tested in 2-arm olfactometer with the view to identifying possible attractants or deterrents that could be used in effective control of storage pest. The results indicated that (a) the female C. maculatus responded discriminatorily to odour stimuli from the bean types tested, (b) eighteen volatile compounds were present in the bean types tested and (c) the volatile compounds identified varied in abundance profile. These suggest that host location and selection behaviours by female C. maculatus are moulded by the types and concentrations of the volatile compounds present in the beans.
Security as a need and a human right
Authors: Tyczkowska-Kowerczyk Anna
Published: October 2021

Security is a concept defined by various aspects. It depends on the terminology applied
in a particular science field. It is differently specified in terms of science branches related
with psychology, philosophy or sociology. Security is also defined in another way in
the security science. It is specified, inter alia, as a state, a process, a good, a need or a
value. However, the aim of this paper is to define security as a need and a human right.
That is why below we make an attempt to answer the following questions: Can security
be defined as a need and a human right? If so, who is their guarantor?
Reducing Power Consumption in Hexagonal Wireless Sensor Networks Using Efficient Routing Protocols
Authors: Alhatimi Razan Khalid , Almousa Omar Saad , Albalas Firas Ali
Published: October 2021

Power consumption and network lifetime are vital issues in wireless sensor network (WSN) design. This motivated us to find innovative mechanisms that help in reducing energy consumption and prolonging the lifetime of such networks. In this paper, we propose a hexagonal model for WSNs to reduce power consumption when sending data from sensor nodes to cluster heads or the sink. Four models are proposed for cluster head positioning and the results were compared with well-known models such as Power Efficient Gathering In Sensor Information Systems (PEGASIS) and Low-Energy Adaptive Clustering Hierarchy (LEACH). The results showed that the proposed models reduced WSN power consumption and network lifetime.

Authors: Anquetil Nicolas , Oliveira Káthia Marçal de
Published: October 2021

A maioria dos engenheiros de software conhece e entende a importância da documentação de um software. Infelizmente, pressões de tempo e custos muitas vezes levam esses engenheiros à não realizar a atividade fundamental de documentação. Somente, quando realizando manutenções posteriores a necessidade de melhor documentação surge como fator essencial. Para manter ativos sistemas antigos sem documentação ou mal documentados, as empresas precisam cada vez mais recursos na manutenção de software. É necessário, portanto, redocumentar esses software para possibilitar uma melhor manutenção atual e futura. Este artigo apresenta um processo de redocumentação de software projetado levando em consideração dois aspectos: a escassez de recursos para realizar essa atividade e o uso de uma abordagem baseada em engenharia reversa, ou seja, a partir do código fonte para níveis mais abstratos de documentação. Este artigo apresenta ainda lições aprendidas obtidas do acompanhamento de uso desse processo em empresas.

A Adaptação de Áreas-Chave de Processo do SW-CMM ao Processo de Reengenharia Orientada a Objetos
Authors: Lemos Gizelle Sandrini , Penteado Rosângela Ap. Dellosso
Published: October 2021

A reengenharia orientada a objetos de sistemas legados procedimentais pode ser realizada de diversas formas com o auxilio de diversos métodos e processos. Um deles é através de linguagem ou família de padrões. A preocupação com a qualidade do processo de desenvolvimento é constante nas empresas, porém o mesmo não ocorre com o processo de reengenharia. Nesse sentido, este artigo apresenta cinco padrões de processo que cuidam do planejamento e do acompanhamento de um processo de reengenharia orientada a objetos de sistemas legados desenvolvidos sem essas características. Esses padrões foram desenvolvidos com base na adaptação das áreas-chave de processo para alcance do nível 2 de maturidade do SW-CMM e incluídos no PRE/OO (Processo de Reengenharia Orientada a Objetos) que agrupa, além desses, outros quinze padrões relacionados à condução do processo de reengenharia. O PRE/OO é composto de sete clusters de padrões sendo que os relacionados à qualidade de processo visam trazer para o processo de reengenharia as diretrizes já utilizadas no processo de desenvolvimento de software. Um estudo de caso com sistema Delphi sem características orientadas a objetos é utilizado para exemplificar o processo sendo o sistema alvo re-implementado na mesma linguagem com características orientadas a objetos.

Authors: Aranda Jorge Arthur Schneider , De Carvalho Juliano Varella , Barbosa Jorge Luis Victória
Published: October 2021

Wearable devices emerged from the advancement of communication technology and the miniaturization of electronic components. These devices periodically monitor the user’s vital signs and generally have low battery life. This thesis proposes Odin, a model for optimized collection of vital signs based on adaptive strategies. The comparison with related works indicates that Odin is the only proposal that presents an adaptive collection of vital signs, which allows the optimized generation of context history. The research validation is divided in three groups. In the first group, simulations were performed in different scenarios, through requisition control, an increase of 114% in battery life was obtained in the adaptive scenario compared to a collection without adaptivity. In the second group, the Odin model was applied to a real physiological data-base and allowed for a reduction in the number of requests due to the adaptability of the collection. This reduction optimized battery consumption by 66% compared to a collection without adaptability. Finally, in the third group, the model was applied in collecting data through an Arduino and also a cardiac monitoring strap available on the market (Polar H7). During this third part of the evaluation, savings of 18% were observed in the power consumption of the mobile devices involved in the data collection.

Authors: Alves Antonio , Pereira Antônio , Cecilio Pablo , Pena Nayara , Viegas Felipe , Tuler Elisa , Dias Diego , Rocha Leonardo
Published: October 2021

In this work, we propose a framework that automatically extracts semantic topics from scientific publications related to research on COVID-19. The framework has four main building blocks: (i) preprocessing, (ii) topic modeling, (iii) topic correlation with authors and institutions, and (iv) summarization interface. The first block corresponds to the application of pre-processing strategies in texts on the considered articles and the definition of their semantic representation. The topic modeling block aims to fi nd semantic topics in the publications used. The third block correlates these topics with the articles themselves and the authors, institutions, and countries related to each article. The summary interface provides an intuitive view for all these analyses. Our evaluation shows that our framework is capable of automatically extracting relevant characteristics from the articles, identifying the main themes addressed by them, as well as the correlation of researchers, institutions and countries for diff erent topics of research on COVID-19.

A finalidade deste artigo é relatar a relevância da utilização dos CAQDAS (computer assisted qualitative data analysis software) na coleta e na análise dos discursos da Mídia Impressa Nacional publicados desde o aparecimento do MST (Movimento dos Trabalhadores Rurais Sem-terra), 17 de abril de 1984, até o ano de 2014, quando o movimento completou 30 anos de existência. Este levantamento justifica-se pela importância do MST na formação de um novo cenário sobre a questão fundiária no Brasil, como também, na capacidade deste movimento social em influenciar o Estado Brasileiro na elaboração e produção de “políticas públicas transversais” (IVO, 2005), que impulsionaram a mitigação da pobreza no meio rural, a concepção de novas tecnologias para a agricultura familiar e a criação de novos espaços educacionais voltados para a população ligada à agricultura familiar e agroecológica. Por outro lado, visando complexificar o objetivo desta investigação, esta pesquisa também teve como meta compreender o processo de burocratização do MST (Movimento dos Trabalhadores Rurais Sem-terra) a partir do momento em que este Movimento Social escolheu aproximar-se da estrutura burocrática do Estado, elegendo suas lideranças para cargos no legislativo, como também, cedendo seus quadros para governos municipais, estaduais e federais.
Parallels between the Developing Vascular and Neural Systems: Signaling Pathways and Future Perspectives for Regenerative Medicine
Authors: Elorza Ridaura Idoia , Sorrentino Stefano , Moroni Lorenzo
Published: October 2021

Neurovascular disorders, which involve the vascular and nervous systems, are common. Research on such disorders usually focuses on either vascular or nervous components, without looking at how they interact. Adopting a neurovascular perspective is essential to improve current treatments. Therefore, comparing molecular processes known to be involved in both systems separately can provide insight into promising areas of future research. Since development and regeneration share many mechanisms, comparing signaling molecules involved in both the developing vascular and nervous systems and shedding light to those that they have in common can reveal processes, which have not yet been studied from a regenerative perspective, yet hold great potential. Hence, this review discusses and compares processes involved in the development of the vascular and nervous systems, in order to provide an overview of the molecular mechanisms, which are most promising with regards to treatment for neurovascular disorders. Vascular endothelial growth factor, semaphorins, and ephrins are found to hold the most potential, while fibroblast growth factor, bone morphogenic protein, slits, and sonic hedgehog are shown to participate in both the developing vascular and nervous systems, yet have not been studied at the neurovascular level, therefore being of special interest for future research.
Perceiving fairness in an unfair world: System justification and the mental health of girls in detention facilities
Authors: Sichel Corianna E. , Javdani Shabnam , Yi Jacqueline
Published: October 2021

Psychologists in the helping professions have long accepted the idea that cognitions have implications for mental health and wellbeing. Community psychologists have further established the importance of context and systems in the etiology of mental health problems. In this paper, we argue that as a discipline that prioritizes social justice, community psychology should consider associations between cognitions about structural and systemic inequality and individual mental health, particularly in marginalized populations. As one illustration of this argument and its complexities, we asked if and to what degree mental health was concurrently associated with adolescents' beliefs in societal fairness (i.e., system‐justifying beliefs), attending to gender differences. Our findings were informed by a sample of 196 adolescents residing in detention facilities (49.50% girls; 51.75% Black/Caribbean, 21.68% multiracial; 15.38% Hispanic/Latine; 27.98% LGBTQ+). These youth represent an understudied group in the research literature addressing fairness beliefs and their influence on wellness. Results suggested that boys were more likely to endorse societal fairness compared to girls, but these beliefs were unrelated to their mental health. However, we found a significant gender moderation such that girls who perceived society to be fair reported lower levels of internalizing and externalizing mental health problems. We discuss implications for theory, research, and intervention.

Published: October 2021

Objective

Germline loss‐of‐function mutations in DEPDC5, and in its binding partners (NPRL2/3) of the mammalian target of rapamycin (mTOR) repressor GATOR1 complex, cause focal epilepsies and increase the risk of sudden unexpected death in epilepsy (SUDEP). Here, we asked whether DEPDC5 haploinsufficiency predisposes to primary cardiac defects that could contribute to SUDEP and therefore impact the clinical management of patients at high risk of SUDEP.

Methods

Clinical cardiac investigations were performed in 16 patients with pathogenic variants in DEPDC5, NPRL2, or NPRL3. Two novel Depdc5 mouse strains, a human HA‐tagged Depdc5 strain and a Depdc5 heterozygous knockout with a neuron‐specific deletion of the second allele (Depdc5c/−), were generated to investigate the role of Depdc5 in SUDEP and cardiac activity during seizures.

Results

Holter, echocardiographic, and electrocardiographic (ECG) examinations provided no evidence for altered clinical cardiac function in the patient cohort, of whom 3 DEPDC5 patients succumbed to SUDEP and 6 had a family history of SUDEP. There was no cardiac injury at autopsy in a postmortem DEPDC5 SUDEP case. The HA‐tagged Depdc5 mouse revealed expression of Depdc5 in the brain, heart, and lungs. Simultaneous electroencephalographic–ECG records on Depdc5c/− mice showed that spontaneous epileptic seizures resulting in a SUDEP‐like event are not preceded by cardiac arrhythmia.

Interpretation

Mouse and human data show neither structural nor functional cardiac damage that might underlie a primary contribution to SUDEP in the spectrum of DEPDC5‐related epilepsies. ANN NEUROL 2022;91:101–116

Published: October 2021

Background

SARS‐CoV‐2 disease (COVID‐19) induces endothelial damage and sustained hypoxia and facilitates immobilization as factors of hypercoagulability.

Objectives

The objective of our study was to assess the prevalence of venous thromboembolic disease (VTD) in COVID‐19 patients and the usefulness of VTD screening based on age‐adjusted D‐dimer and point‐of‐care ultrasound (POCUS).

Patients/Methods

We conducted a single cohort, prospective observational study in 102 consecutive hospitalized patients.

Results

A total of 102 POCUS and 39 pulmonary computed tomography angiography (PCTA) were performed diagnosing 27 VTD (26.5%): 17 deep vein thrombosis (DVT) (16.6% positive POCUS) and 18 pulmonary embolism (PE) (46.2% positive PCTA). COVID‐19 patients with VTD were older (P < .030), had higher D‐dimer (P < .001), higher International Society on Thrombosis and Hemostasis score (P < .001), and higher mortality (P = .025). However, there were no differences in inflammatory laboratory parameters neither in the cytokine storm syndrome (CSS) development. The ROC curve for D‐dimer showed an AUC of 0.91. We have evidenced that patients with D‐dimer between 2000 and 6000 ng/mL could benefit from a screening strategy with POCUS given the high sensitivity and specificity of the test. Furthermore, patients with D‐dimer ≥6000 ng/mL should undergo POCUS and PCTA to rule out DVT and PE, respectively.

Conclusions

In our cohort, 26.5% of the patients presented VTD. Screening strategy based on age‐adjusted D‐dimer and POCUS proved high sensitivity and specificity. Future trials focused on screening strategies are necessary to early detect the presence of DVT and PE and determine thromboprophylaxis strategies in patients with COVID‐19.
Evaluation of a custom‐designed human–robot collaboration control system for dental implant robot
Authors: Kan Tian‐shu , Cheng Kang‐jie , Liu Yun‐feng , Wang Russell , Zhu Wei‐dong , Zhu Fu‐dong , Jiang Xian‐feng , Dong Xing‐tao
Published: October 2021

Background

The purpose of this study is to develop a methodology to better control a human–robot collaboration for robotic dental implant placement. We have designed a human–robot collaborative implant system (HRCDIS) which is based on a zero‐force hand‐guiding concept and a operational task management workflow that can achieve highly accurate and stable osteotomy drilling based on a surgeon's decision and robotic arm movements during implant surgery.

Method

The HRCDIS brings forth the robot arm positions, exact drilling location, direction and performs automatic drilling. The HRCDIS can also avoid complex programing in the robot. The purpose of the study is to evaluate the accuracy of drilling resulting from our developed operational task management method (OTMM). The OTMM can enable the robot to switch, pause, and resume drilling tasks. The force required for hand‐guiding in a zero‐force control mode of the robot was detected by a 6D force sensor. We compared our force data to those provided by the manufacturer's manual. The study was conducted on a phantom head with a 3D‐printed jaw bone to verify the validity of our HRCDIS. We appraised the discrepancies between free‐hand drillings and the HRCDIS controlled drillings at apical centre and head centre of the implant and implant angulation to the baseline data from a virtual surgical planning model.

Results

The average required force used by hand‐guiding to operate the robot with HRCDIS was near 7 Newton which is much less than the manufacturer's specification (30 Newton). The results from our study showed that the average error at implant head was 1.04 ± 0.37 mm, 1.56 ± 0.52 mm at the implant apex, and deviation of implant angle was 3.74 ± 0.67°.

Conclusions

The results from this study validate the merit of the human–robot collaboration control by the HRCDIS. Based on the improved navigation system using HRCDIS, a robotic implant placement can provide seamless drilling with ease, efficiency and accuracy.
Gain‐scheduled robust control for multi‐agent linear parameter‐varying systems with communication delays
Authors: Chen Yangzhou , Huang Xiaolong , Zhan Jingyuan
Published: October 2021

This study deals with the problem of gain‐scheduled robust control for multi‐agent linear parameter varying (LPV) systems with or without communication delays. The system matrices are assumed to depend on the scheduling parameters, which are supposed to be time‐varying within a priori known bounds. First, a linear transformation matrix is constructed from the directed spanning tree of the communication topology of the agents, which equivalently transforms the robust consensus control problem of multi‐agent LPV systems into the robust stability problem of a set of parameter‐dependent systems. What's more, the effect of the time‐varying communication delays is considered, and consensus condition in terms of linear matrix inequalities (LMIs) is derived by using the parameter‐dependent Lyapunov–Krasovskii approach. Then, the control gain matrices are obtained through solving a convex optimization problem. Finally, a numerical example is provided to illustrate the effectiveness of the proposed method.

The environmental life cycle assessment was carried out from “cradle to gate” using the SimaPro software and the ILCD 2011 Midpoint+ methodology. The boundaries of the system included cultivation of maize, delivery of feedstock to the plant, energy production, storage and transport of digestate. The results show that transport of liquid manure induces the highest environmental impact.

Objective

To evaluate the prognostic implications of longitudinal long-term changes beyond the biological variation of high-sensitivity cardiac troponin T (hs-cTnT) in outpatients with stable or asymptomatic cardiovascular disease (CV) and to assess possible differences in the prognostic value while using reference change value (RCV) and minimal important differences (MID) as metric for biological variation.

Methods

Hs-cTnT was measured at index visit and after 12 months in outpatients presenting for routine follow-up. The prognostic relevance of a concentration change of hs-cTnT values exceeding the biological variation defined by RCV and MID of a healthy population within the next 12 months following the stable initial period was determined regarding three endpoints: all-cause mortality (EP1), a composite of all-cause mortality, non-fatal myocardial infarction and stroke (EP2), and a composite of all-cause mortality, non-fatal myocardial infarction, stroke, hospitalization for acute coronary syndrome (ACS) or decompensated heart failure, and planned and unplanned percutaneous coronary interventions (PCI, EP3).

Results

Change in hs-cTnT values exceeding the biovariability defined by MID but not by RCV discriminated a group with a higher cardiovascular risk profile. Changes within MID were associated with uneventful course (NPV 91.6–99.7%) while changes exceeding MID were associated with a higher occurrence of all endpoints within the next 365 days indicating a 5.5-fold increased risk for EP 1 (p = 0.041) a 2.4-fold increased risk for EP 2 (p = 0.049) and a 1.9-fold increased risk for EP 3 (p < 0.0001).

Conclusions

In stable outpatients MID calculated from hs-cTnT changes measured 365 ± 120 days apart are helpful to predict an uneventful clinical course.

Expectations and realities: Examining adolescent students’ game jam experiences
Authors: Aurava Riikka , Meriläinen Mikko
Published: October 2021

This article describes the expectations and experiences of young (16 to 19 year old) digital game jam participants (N = 34) who attend Finnish general upper secondary schools. Game jams are a form of game creation: events where games are made in co-operation. They are widely used in game design education and in addition, when participated voluntarily, learning has been reported as an important motivation. The existing literature mostly concentrates on game jams for adults, and informal or non-formal learning. This article is adding to the literature by examining learning in formal education for adolescents. As part of our research, we have organised game jams in formal general education, and this article is based on the pre-event and post-event surveys of three game jam events. The article maps 1) the motivations to attend a school related game jam, 2) the expectations and apprehensions the would-be participants have, 3) what kind of learning game jams promote, and 4) how does attending a game jam affect participants’ attitudes and apprehensions regarding learning, STEAM and information technology, and their own skills. Our results indicate the creative side of digital game making, desire to learn new skills and make new friends to be the main motivations for participation, and the lack of confidence in technical skills to cause most anxiety before the jam event. The effects of attending a game jam are mostly positive, with the participants reporting learning experiences in several soft and technical skills and increased motivation to take part in creative and co-creative projects. A gendered result can be seen in the participants’ altered stance on technology and programming: girls and non-binary students report technology and programming being easier and more fun than they had thought before attending a game jam event, which is well in line with previous research on STEM/STEAM education and gender.
Spacetimes with continuous linear isotropies III: null rotations

The exceptions where invariance of the second derivatives is additionally required to ensure this conclusion are Petrov type N Einstein spacetimes, spacetimes containing “pure radiation” (a Ricci tensor of Segre type [(11,2)]), and conformally flat spacetimes with a Ricci tensor of Segre type [1(11,1)] (a “tachyon fluid”).
Participatory injustice in Mexico’s Readiness process to Reduce Emissions from Deforestation and forest Degradation (REDD +)

Published: October 2021

Since 2007 many developing countries have laid groundwork for Reducing Emissions from Deforestation and forest Degradation and sustainable management and conservation of forests (REDD +) under the auspices of the United Nations Framework Convention on Climate Change (UNFCCC). REDD + is aimed at incentivizing forest conservation and management in developing countries through policy programmers and local projects, which should in theory enhance the participation of very diverse actors in forest policy and governance. Here we explore the early years of REDD + in Mexico focusing on the alleged “participatory” nature of the REDD + initiative. Based on interviews and field observations with those involved in drafting the REDD + national strategy and in the implementation of small-scale pilot project activities, we investigate the meaning of participation for REDD + actors, their aspirations in this regard, and how procedural justice issues are being considered in early policy implementation. We demonstrate that the process set in motion to draft the strategy did not sufficiently involve sub-national governance levels, thus reducing the legitimacy of REDD + efforts, particularly in rural communities. We suggest that rural local actors should be further involved in REDD + decision-making forums, be provided with more information for a good understanding of REDD + implementation (e.g., pilot projects), and most importantly, be given a real chance to implement REDD + activities grounded on their own institutions and land-use practices.
Robot Autonomy vs. Human Autonomy: Social Robots, Artificial Intelligence (AI), and the Nature of Autonomy
Authors: Formosa Paul
Published: October 2021

Social robots are robots that can interact socially with humans. As social robots and the artificial intelligence (AI) that powers them becomes more advanced, they will likely take on more social and work roles. This has many important ethical implications. In this paper, we focus on one of the most central of these, the impacts that social robots can have on human autonomy. We argue that, due to their physical presence and social capacities, there is a strong potential for social robots to enhance human autonomy as well as several ways they can inhibit and disrespect it. We argue that social robots could improve human autonomy by helping us to achieve more valuable ends, make more authentic choices, and improve our autonomy competencies. We also argue that social robots have the potential to harm human autonomy by instead leading us to achieve fewer valuable ends ourselves, make less authentic choices, decrease our autonomy competencies, make our autonomy more vulnerable, and disrespect our autonomy. Whether the impacts of social robots on human autonomy are positive or negative overall will depend on the design, regulation, and use we make of social robots in the future.
MultiPDF particle filtering in state estimation of nonlinear objects
Authors: Michalski Jacek , Kozierski Piotr , Giernacki Wojciech , Zietkiewicz Joanna , Retinger Marek
Published: October 2021

This paper presents a new particle filter algorithm (MultiPDF) for state estimation of nonlinear systems. The proposed method is a modification of the standard particle filter approach. Due to the strong need for the acceleration of calculations and an improvement in the estimation quality of state estimation, the authors propose a method which enables one to divide the main particle filter into smaller sub-filters with an accordingly smaller number of particles for each one of them. The algorithm has been implemented for various numbers of particles and subordinate parallel filters. Estimation quality has been checked for nine nonlinear objects (both one- and multidimensional) and evaluated through the quality index, average root-mean-squared error. The computation time of the particle filter algorithm for several hardware configurations has been compared. Based on the obtained results, it can be concluded that, besides the computation acceleration, the parallelization of the particle filter’s operation also improves the estimation quality.
Bocheński’s model of the development of logic
Authors: Tkaczyk Marcin
Published: October 2021

According to Bocheński’s description of the history of formal logic, there clearly is some objective development, though far from being cumulative or linear. The history of logic throughout the world consists of three relatively short pinnacles preceded by also short periods of awakening and followed by periods of extensive commentary running into long periods of standstill and decadence, when nearly all achievements are consigned to oblivion.
