Authors: Le H. K.
Published: October 2022

The Multi-Criteria Decision-Making (MCDM) process of milling SNCM439 steel is presented in this study. In this experimental study, 3 cutting tool parameters, namely the number of pieces, cutting piece material, and tip radius were considered and 3 cutting mode parameters, i.e. cutting speed, feed rate, and depth of cut changed in each experiment. SR and MRR are selected as the output parameters of the milling process. The PARIS method was used for MCDM, in which, the weights of SR and MRR were determined by 3 methods, namely AW, EW, and MW. Twenty-seven sets of ranking results for 27 alternatives (experiments) are presented. The GINI index was used to evaluate the stability of ranking alternatives. The results have determined the value of 6 input parameters to ensure the minimum SR and the maximum MRR simultaneously.

Published: October 2022

This study considered a mathematical model to describe the process of a quasi-static contact between a piezoelectric body and an electrically conductive foundation. The behavior of the material was modeled with a nonlinear electro-viscoelastic constitutive law, the contact was frictionless, and the result was described with the Signorini condition. A variational formulation was derived for the problem, proving the existence and uniqueness of a weak solution of the model. The proof was based on arguments for nonlinear equations with maximal monotone operators.

Published: October 2022

An All-Digital Phase-Locked Loop (ADPLL) is an architecture that is widely employed in the communication system due to the advancement of the Complementary Metal-Oxide-Semiconductor (CMOS) technology process. A 2.4GHz Radio Frequency Identification (RFID) system needs a frequency synthesizer in the local oscillator architecture of the transceiver to generate a stable frequency tuning range Therefore, in this paper, a Digital Phase-Frequency Detector (DPFD) is designed to achieve the phase and frequency acquisition in the ADPLL system. The proposed DPFD is divided into two main parts, the first is the Phase Detector (PD) and the second is the Frequency Detector (FD). The PD has managed to detect the presence of the phase difference by recognizing two different input signals. The FD, on the other hand, is capable to detect the higher frequency by identifying the output signals from the PD in digital formation. In addition, a control unit module is developed to control and adjust the Preset Word (PW) for the system by using a binary search scheme. Comparison results show that the final value of the PW from the simulation is the same as from the manual calculation (theoretical values). The digital PFD and the PW control modules are designed and simulated by using Verilog HDL code. These two designed modules will be integrated into the targeted ADPLL to achieve fast locking performance and ultra-low power for Ultra-High Frequency (UHF) RFID applications.
The Feasibility of Applying Waste Concrete as Coarse Aggregates in New Concrete

Published: October 2022

This paper presents a study on the possibility of replacing natural coarse aggregates with recycled aggregates in concrete in terms of strength, namely compressive strength and flexural strength. The concrete was designed to have a 25MPa compressive strength and an 8cm slump. The replacement rates of natural aggregates with recycled coarse aggregates were 0%, 10%, 15%, and 20%. The test samples were compressed to determine their strength value after 28 days of curing. The research results give a more complete assessment of the efficiency of the use of recycled raw aggregates instead of natural aggregates in concrete. The results indicate that using recycled aggregates is feasible due to the small decrease in concrete strength. The experiment shows that up to 20% replacement, the recorded reduction in the strength of concrete is lower than 15%. However, it is indispensable that the strength of concrete should be enhanced when recycled aggregates are used. According to previous works, fiber reinforcement may be an effective solution. Therefore, to further develop research using recycled aggregates, it is necessary to consider using different fibers to strengthen the concrete. The fiber content can be used in the range of 0-1% of the weight of concrete.
Feature Extraction of EEG Signals for Seizure Detection Using Machine Learning Algorthims
Authors: Alsuwaiket M. A.
Published: October 2022

Epilepsy is a central nervous system disorder in which brain activity becomes abnormal and causes periods of unusual behavior and sometimes loss of awareness. Epilepsy is a disease that may affect males or females of all ethnic groups and ages. Detecting seizures is challenging due to the difference in human behaviors and brain signals. This paper aims to automate the extraction of electroencephalogram (EEG) signals without referring to doctors using two feature extraction methods, namely Wavelet Packet decomposition (WPD) and Genetic Algorithm-Based Frequency-Domain Feature Search (GAFDS). Three machine learning algorithms were applied, namely Conventional Neural Networks (CNNs), Support Vector Machine (SVM), and Random Forest (RF) to diagnose epileptic seizures. The results achieved from the classifiers show a higher accuracy rate using CNNs as a classifier and GAFDS as feature extraction reaching 97.93% accuracy while the accuracy rate of the SVM and RF was 94.49% and 88.03% respectively.

Authors: Almasoudi S. S. , Albayati A. H. K.
Published: October 2022

The main objective of this research is to find out the effect of deviation in the aggregate gradients of asphalt mixtures from the Job Mix Formula (JMF) on the general mixture performance. Three road layers were worked on (wearing layer, binder layer, and base layer) and statistical analysis was performed for the data of completed projects in Baghdad city, and the sieve that carried the largest number of deviations for each layer was identified. No.8 sieve (2.36mm), No.50 sieve (0.3mm), and 3/8'' sieve (9.5mm) had the largest number of deviations in the wearing layer, the binder layer, and the base layer respectively. After that, a mixture called Mix 1, was made. This mixture was selected from a number of completed mixtures, and it represents the worst mixture. Mix 1 was compared with two other mixtures, Mix 2 and Mix 3, Mix 2 represents the mean of JMF for the gradients of aggregates, and Mix 3 is the same as Mix 1 except for the sieve that contains the largest number of deviations, so the gradient of aggregates for it is the mean of JMF. Fifteen Marshall specimens were made for each mixture and for each layer in order to know the differences in Marshall properties between the mixtures. Also, 6 specimens were made for each mixture (the total is 18 specimens for each layer) to check the indirect tensile strength, for the purpose of knowing the mixtures' susceptibility to moisture. Finally, 1 specimen was made for each mixture for repeated load test for the purpose of knowing the performance of the mixtures with respect to permanent deformation. The tests showed that the performance of Mix 2 and Mix 3 was improved in comparison with Mix 1. The deviation of the aggregate gradients in specific sieves may be higher than the limits of the JMF or it may be less, and in both cases, the implementation of a mixture like Mix 1 for the streets is bad for the performance of the road and failures occur due to the wrong implementation of the JMF. On the other hand, there are much better mixtures in all respects such as Mix 2 and Mix 3, and if they are implemented on the streets, they will certainly have much better.
Distribution of intraocular pressure in a Swedish population
Authors: Häkkinen Maria , Ekström Curt
Published: October 2022

Background: Increased intraocular pressure (IOP) and pseudoexfoliation (PEX) are major risk factors for open-angle glaucoma (OAG), an age-related neurodegenerative disease of significant importance for public health. There are few studies on the distribution of IOP in populations where PEX is a common finding.

Methods: The distribution of IOP was studied in 733 subjects 65–74 years of age, examined in a population survey in the rural district of Tierp, Sweden, 1984–86. The difference between the right and left eye and the effect of which eye was measured first were examined. Odds ratios, adjusted for age and sex, according to Mantel-Haenszel (ORMH), were calculated to estimate predictors of increased IOP, defined as a pressure ≥20 mm Hg in either eye. The pressure was measured with Goldmann applanation tonometry. Automated perimetry was used to identify OAG.

Results: The distribution of IOP was close to that of other European-derived populations. The pressure in the first measured eye was higher than in the second measured eye. Increased IOP was related to OAG and PEX, ORMH 8.97 (95% confidence interval [CI] 3.84–20.9) and 2.40 (95% CI 1.53–3.76), respectively. An IOP ≥20 mm Hg increased the risk of having been diagnosed with diabetes (ORMH 1.83; 95% CI 1.08–3.09).

Conclusion: In this study of subjects 65–74-years-old in Sweden, the distribution of IOP was close to that of other European-derived populations. Although the difference was small, the pressure in the first measured eye was higher than in the second eye. Increased IOP was strongly related to untreated OAG and PEX.

Published: October 2022

Let X be a metric continuum and n a positive integer. Let Fn (X) be the hyperspace of nonempty subsets of X with at most n points. If 0 < m < n, we consider the quotient space Fnm (X) = Fn (X)/Fm (X). Given a mapping f  from X into X, we consider the induced mappings fn from Fn (X) into Fn (X) and fnm  from Fnm (X) into Fnm (X). In this paper we study the relations among the dynamics of the mappings f, fn, and fnm  and we answer some questions, by F. Barragán, A. Santiago-Santos and J. Tenorio, related to the properties: minimality, irreducibility, strong transitive and turbulence.

Published: October 2022

Objectives: This study aimed to assess the proportion of women who underwent postpartum evacuation and were histopathologically confirmed to have retained products of conception (RPOC), compare the reliability of histopathology and ultrasound (US) in determining the presence of RPOC, and assess the maternal complications associated with postpartum evacuation. Methods: A retrospective cross-sectional study was conducted on all women who delivered and had postpartum evacuation at a tertiary teaching hospital in Oman over 11 years from May 2009 to May 2020. The participants were divided into two groups based on their histopathology results. McNemar test was used to compare the sonographic results with the histopathological findings. Results: A total of 151 women were included in this study. The diagnosis of RPOC was confirmed in histopathological reports of 64 (42.4%) women (group 1) but not in 87 (57.6%) women (group 2). There was no significant difference between the two groups in maternal characteristics. Parameters of clinical presentation including fever and abdominal pain were significantly different between the two groups (p =0.026 and p =0.028, respectively). Vaginal bleeding was not significantly different between the groups (p =0.255). Pelvic US detected RPOC in 135 (89.4%) women whereas the histopathology confirmed it in 64 (42.4%) women (p < 0.001). The sensitivity of US compared to histopathology in diagnosing RPOC was 98.4% (95% CI: 91.60–99.96) and the specificity was 17.2% (95% CI: 9.98–26.84). The overall diagnostic accuracy of US in detecting RPOC was 51.7%. Two (1.3%) women had hysterectomy as a result of the evacuation. Histopathology showed smooth muscle in 20 (13.2%) women. Significant bleeding during surgery occurred in 17 (11.3%) cases. Conclusions: Diagnosis of postpartum RPOC is challenging. Our results highlighted the complexity of diagnosing RPOC. Special training is needed for doctors to diagnose RPOC from transvaginal scans. A multicenter study in Oman with a larger sample size is recommended to confirm our findings.
Deconstructing In Vitro Corrosion of Pure Mg: Influence of Serum Biomolecules and Phosphate Ions
Authors: Mohan Sanjay Krishna , Turney Terence , Thomas Sebastian
Published: October 2022

Anomalies have been reported between biocorrosion rates of Mg alloys determined in in vitro and in vivo environments. In vivo environments contain serum biomolecules together with inorganic ions, while in vitro environments typically used for testing may or may not include serum biomolecules. In vitro corrosion testing on pure Mg in a series of electrolyte compositions has identified the influence of different biomolecular and inorganic species on the biocorrosion of pure Mg. Electrochemical analyses and electron microscopy indicate that serum biomolecules tend to accelerate the corrosion of Mg, while phosphate ions in synergy with calcium ions inhibit Mg corrosion. However, serum concentrations >30 vol% in test media lead to decreased corrosion of pure Mg. This indicates that variations in Mg biocorrosion rates seen in in vitro and in vivo media could be attributed to differences in serum concentrations in the respective media.

Published: October 2022

O fenômeno da inovação social (IS) não é considerado novo, mas sua conceituação teórica ainda requer certo nível de aprofundamento científico. Visando contribuir com essa temática, este estudo busca identificar, a partir de uma análise teórico-conceitual, quais as características primordiais que compõem o espectro da inovação social. A partir da discussão conceitual e da análise de proposições de estudos anteriores, observou-se que a inovação social implica, sobretudo, em desenvolvimento sustentável, inclusão, equidade e concessão de direitos. Ademais, foram propostas quatro categorias analíticas para os estudos em inovação social, a saber: inovatividade; motivação social; construção coletiva; e potencial transformador para a sociedade. Em relação ao raio de ação, indicou-se que o fenômeno socialmente inovador pode ocorrer nos níveis incremental, institucional e disruptivo. Por fim, observou-se que, embora corra o risco de ser distorcida pelo sistema neoliberal, a inovação social pode ser um caminho de resistência e contraposição às desigualdades e à apatia social em relação ao sofrimento alheio.
Narrar para negar: a busca por um alto e puro amor ou a intransitividade do verbo amar
Authors: Domingues Coelho Elisa
Published: October 2022

Amar, verbo intransitivo - idílio, romance de Mário de Andrade publicado em 1927, e Sob o olhar malicioso dos trópicos, romance de Barreto Filho publicado em 1929, são duas obras que, apesar de sua proximidade temporal, não poderiam estar mais distantes em sua proposição estética: a primeira, filiada ao modernismo paulista de 22; a segunda, ao movimento espiritualista. A proposição deste artigo de colocar essas obras tão díspares lado a lado é o tema que compartilham: a moral sexual, ou ainda, a inconciliação entre amor e sexo. Assim, o romance de Mário de Andrade tem por protagonista Fräulein Elza que, sendo contratada para fazer a iniciação sexual de Carlos, filho de uma tradicional família paulistana, define-se como “professora de amor”; ao passo que, no romance de Barreto Filho, embora o protagonista André Lins não almeje outra coisa senão o amor elevado, é o “olhar malicioso” o cerne e presença imperativa do início ao fim da narrativa. São, portanto, dois romances tensionados entre amor e sexo, em que, para se buscar o primeiro, nega-se o segundo, fornecendo, desse modo, uma interessante perspectiva da ficcionalização da moral sexual que tanto ocupará as páginas de nossa prosa nos anos seguintes.

Authors:   , Madonda Sandine Ewart
Published: October 2022

The proposed input of this empirical study was the formulation of an exploratory Workplace Skills Plan model aimed at discovering the link between the effect of Workplace Skills Plan and human resource development that the organisation achieves its objectives. It is therefore important to state that the problem identified is a chronic poor performance of the organisation because of the lack of critical skills at the local government level. This was achieved by determining the influence of Workplace Skills Plan towards Human Capital Development at the eThekwini Municipality. The study used a quantitative research method to obtain the determined research objectives. Non- probability sampling technique was used to collect data from the targeted population. Convenience sampling technique was used to generate sample of the study. The researcher selected respondents who completed, signed and returned 2018-2019 WSP forms during consultation and meeting with their managers. The researcher did not send the questionnaires to employees who were trained in the same period but did not complete the WSP forms. The data for these delegates is available on Document Record System, which is human resource system where eThekwini Municipality keep track of WSP. The structured self-administered questionnaire was used as a tool for data collection. In this study, 279 respondents completed and returned the questionnaire. The study used a data analysis instrument called Statistical Package for the Social Science (SPSS version 20) and AMOS version 20. The results suggest that there is a critical role played by Workplace Skills Plan on Human Capital Development in the workplace. This agrees with what another research in the same field have observed. Data analysis showed that Workplace Skills Plan is useful in boosting the overall human capital development in the workplace and therefore can be used as a tool of Human Capital Development. Workplace Skills Plans assist companies to adjust to labour market flexibility and train for what the market requires and to maximise the returns from the large investment in skills and tertiary qualifications. The findings of this study indicate that training and development have a direct and indirect positive effect on Human Capital Development. The study recommends that organisations maximise effective development of human capital development initiatives to sustain effective organisational performance, improve employee performance, productivity, employee competencies, efficiency, effectiveness, and long-term organisational success. Thus, municipalities must invest in their existing human capital through taking care of their development needs to ensure sustained organisational performance and attainment of organisational goals.
The nature and extent of sustainable water management practices in the accommodation sector in Zimbabwe
Authors:   , Ushamba Kudzai Norman
Published: October 2022

International tourism has grown to become one of the largest economic sectors in the world. The growth of tourism is not merely taking place in the so-called developed economies, but also in developing economies. In Africa, the growth of tourism has led to the proliferation of many forms of accommodation and lodging facilities. With a significant number of African nations facing fresh-water problems, water stress has now become a challenge in most destinations. The accommodation sector of the tourism industry has been identified as one of the biggest consumers of water through its various activities and facilities. Tourism, a major fiscus contributor is crucial to the economy of Zimbabwe hence its sustainability is vital especially during this time when world is grappling climate change. The last two or more decades have witnessed the majority of Zimbabwean citizens facing fresh water supply problems, especially in cities and towns which are hotspots for tourism. This study examined the nature and extent of water management practices in the accommodation sector in Zimbabwe. The study examined the level of water use in the accommodation sector in Zimbabwe, and the extent to which water conservation practices are currently being undertaken by this sector. The study further examined challenges facing water conservation in the accommodation sector in Zimbabwe. A ‘mixed method’ research approach was used in this study. Questionnaires were administered to managers of 203 accommodation facilities in the country. Expert views were sort from key stakeholders whose organisations, regulations and policies affect the tourism industry. The study found that accommodation establishments in Zimbabwe have been reactive to climate change induced water stress and have been applying several water-conservation measures. The study also found that there is non-enforcement of regulations on government policies and lack of proper awareness as to the monetary benefits of practicing water conservation in the accommodation sector in Zimbabwe. The study concludes that without proper planning, communication, and enforcement of regulations large amounts of fresh water will continue to be wasted to the deprivation of communities.
Improving node localization and energy efficiency for wireless sensor networks using hyper-heuristic optimization algorithms
Authors:   , Aroba Oluwasegun
Published: October 2022

Within the growing Internet of Things (IoT) paradigm, a Wireless Sensor Network (WSN) is a critical component. In a WSN, sensor node localization is typically utilized to identify the target node’s current location at the sink node (SN). This allows local data to be analysed, making it more meaningful. However, there exists an intrinsic problem with node localization and energy efficiency, as identified in the literature, which has led to poor performance, namely, poor estimation, transmission, and detection of the network. This intrinsic problem also directly affects energy efficiency in a WSN, resulting in energy loss and poor node distribution in the WSN. There seems to be no lasting and reliable solution to this intrinsic node localization problem in WSNs. Hence, this research study proposed hyper-heuristic optimization algorithms to improve node localization and energy efficiency in WSNs. This research adopts the Design Research (DR) methodology and the Theory of Modelling and Simulation as the theoretical frameworks of the study. The hyper-heuristic model designed, was considered the conceptual framework of the study. To validate the novel technique, different sizes of sensor networks, namely: - 100 sensor nodes; 100 to 1 500 nodes and 200 to 450 sensor nodes with 20 anchor nodes were simulated in an area measuring 100m x 100m. The novel hyper-heuristic model was implemented in a MATLAB R2020a environment. The hyper-heuristic optimization algorithm’s substantial simulated experiment results were benchmarked utilizing state-of-the-art (modern) techniques to solve challenges related to node localization error, total energy consumed, average consumed packet energy, network throughput, shortest path, dead nodes, packets dispatched to the base station (BS), and the probability of error within the entire network dependent on size. The Data Energy Efficiency Clustering-Gaussian (DEEC-GAUSS) method was used to provide solutions to challenges related to energy efficiency in WSNs. In addition, this research study explored the use of the novel DEEC-GAUSS Gradient Distance Elimination Algorithm (DGGDEA) as the hyper-heuristic optimisation model for localization of nodes in WSNs. DEEC-GAUSS and DGGDEA were valuable additions to the body of knowledge. The results showed that the novel DEEC-GAUSS was the most energy efficient algorithm for 100 sensor nodes and 1000 to 1500 sensor nodes when compared to other stateof-the-art algorithms. Furthermore, the results showed that the novel DGGDEA was able to drastically minimize the node estimation error for sensor nodes. Reliability, accuracy and convergence using hyper-heuristic models to enhance the communication within WSNs has been simulated with evidence that DEEC-GAUSS and DGGDEA has outperformed other stateof-the-art approaches
Wastewater treatment and photo-reduction of CO2 using an integrated magnetized TiO2 anaerobic- photocatalytic system
Authors:   , Tetteh Kweinor Emmanuel
Published: October 2022

Conventionally, the treatment of municipal wastewater involves a sequence of treatment units aimed at reducing pollutants to acceptable discharge levels. Herein wastewater treatment plants in South Africa’s municipalities are being challenged recently due to emerging contaminants (nanomaterials, pesticides, antibiotics, COVID-19 RNA, etc.) that impede their efficiency. This calls for robust technological water solution systems targeted at promoting sustainable water supply and mitigating anthropogenic gas (CO2) emission via biogas production. Against this background, the novel of this study is aimed to develop an integrated AD-AOP (anaerobic digestion – advanced oxidation process) magnetized system to improve wastewater for reuse with biogas production and nanoparticles recoverability benefits. To obtain an optimal balance between robustness and cost-effectiveness of the integrated system, a series of feasibility and engineering works were explored. The first phase involved the synthesis via a co-precipitation technique, characterization, and applicability of the magnetized-photocatalysts (MPCs) for wastewater treatment. Analytically, the scanning electron microscopy and energy dispersive X-ray (SEM/EDX), Fourier transforms infrared spectra, X-ray diffraction (XRD), and Brunauer- Emmett-Teller (BET) techniques showed the tailored MPCs were successfully magnetized. Among the MPCs studied, Fe-TiO2 (with a BET surface area of 62.73 m2 /g) was found as the best with greater potential for above 75% decontamination of the wastewater and methane yield. In the technological design and evaluation, Fe-TiO2 was examined using biochemical methane potential (BMP), biophotocatalytic (BP), biomagnetic (BM), and biophotomagnetic (BPM) systems. Due to the external magnetic field influence on the BPMs, it was found very promising for future adventures. Above all, the novel integrated AD-AOP magnetized system proof of concept showed great potential for recoverability of the MPCs for reuse, reducing the toxicological effects of trace metals (27 elements considered), and improving water and biogas quality. The bioenergy economy of the integrated AD-AOP magnetized system demonstrated net energy being able to subsidize the energy required by the UV-lamp of the AOP system. Conclusively, this finding provides an insight into synthesizing novel MPCs and their applicability for wastewater remediation and biogas production. Also kinetics modeling and response surface methodology (RSM) optimization coupled with artificial neural network (ANN) predictability showed the potential to develop an optimized integrated AD-AOP magnetised system towards the treatment of industrial wastewater, biogas production , and CO2 emission reduction. The prospects necessitate a techno-scientific revolution to upscale the current integrated system into a pilot scale with smart-online monitoring towards improving the wastewater circular economy.

MONETARY POLICY AND SUSTAINABLE DEVELOPMENT GOALS IN NIGERIA
Authors: Chuba Mathias A. , Yusuf Lawal D.
Published: October 2022

Achieving the 2030 sustainable development goals (SDGs) in Nigeria requires sustainable and inclusive economic growth. There is no consensus among economists on the effect of monetary policy on economic growth. The results of previous studies on the effect of monetary policy on economic growth in Nigeria are mixed. The main objective of this paper is to evaluate the effect of monetary policy on economic growth in order to ascertain if monetary policy can be used to achieve SDGs in Nigeria. The effect of monetary policy on economic growth in Nigeria from 1991 to 2020 was evaluated using ordinary least squares regression model. The findings indicated that there is long-run relationship between economic growth and money supply, treasury bill rate and domestic credit provided by banks in Nigeria. The money supply and domestic credit provided by banks had significant positive effect on economic growth; and short-term policy interest rate had significant negative effect on economic growth in Nigeria in line with economic theory. Monetary policy is a veritable tool that can be used to achieve SDGs in Nigeria. Economic growth will increase and SDGs will be achieved in Nigeria if money supply and domestic credit provided by banks are increased and short-term policy interest rate is reduced. Increasing economic growth touches on the objectives of monetary policy of the Central Bank of Nigeria and calls for radical and proactive monetary policy towards achieving SDGs.

Generating images for Supervised Hyperspectral Image Classification with Generative Adversarial Nets
Authors: Osman Hassan Abdalla Abdelkarim , Azlan Norsinnira Zainul
Published: October 2022

With the advancement of remote sensing technologies, hyperspectral imagery has garnered significant interest in the remote sensing community. These developments have inspired improvement in various hyperspectral images (HSI) classification applications, such as land cover mapping, amongst other earth observation applications. Deep Neural Networks have revolutionized image classification tasks in areas of computer vision. However, in the domain of hyperspectral images, insufficient training samples have been earmarked as a significant bottleneck for supervised HSI classification. Moreover, acquiring HSI from satellites and other remote sensors is expensive. Thus, researchers have turned to generative models to leverage the existing data to increase training samples, such as particularly generative adversarial networks (GAN). This paper explores the use of a vanilla GAN to generate synthetic data. The network employed in this paper was built using a deep learning python package, PyTorch and tested on a popular HSI dataset called Indian Pines dataset. The network achieved an overall accuracy of 64%. While promising, there is still room for improvement.
Axis manipulation to solve Inverse Kinematics of Hyper-Redundant Robot in 3D Space
Authors: Winston Sheldon Ijau , Jamali Annisa
Published: October 2022

A solution based on inverse kinematics is required for the robot's end effector, also known as its tip, to reach a target. Current methods for solving the inverse kinematics solution for a hyper-redundant robot in three 3D are generally complex, difficult to visualize, and time-intensive. This requires the development of new algorithms for solving inverse kinematics in a quicker and more efficient manner. In this study, an axis manipulation using a geometrical approach is used. Initially, a general algorithm for a 2 m-link hyper-redundant robot in 3D is generated. The method employed a repetitive basic inverse kinematics solution of a two-link robot on virtual links. The virtual links are generated using a specific geometric proposition. Finally, the 3D solution is generated by rotating about the global z-axis. This method reduces the mathematical complexity required to solve the inverse kinematics solution for a 2-m-link robot. In addition, this method can manage variable link manipulators, thereby eliminating singularity. To demonstrate the effectiveness of the model, numerical simulations of hyper redundant models in 3D are presented. This new geometric approach is anticipated to enhance the performance of hyper-redundant robots, enabling them to be of greater assistance in fields such as medicine, the military, and search and rescue.

En los últimos años surge el concepto de Una Sola Salud que reconoce la interdependencia sistémica al observar que los cambios en la salud humana se expresan de manera sincrónica e indivisible de la salud del ambiente. Nuevas enfermedades y daños crónicos inespecíficos ocurren a la par de la pérdida de biodiversidad y vitalidad. En las últimas décadas venimos observando el surgimiento de “adaptaciones sistémicas” que requieren un abordaje desde la clínica y la toxicología a nivel individual y desde la epidemiología de la complejidad a nivel poblacional. Luego de un largo recorrido de investigaciones, el Hospital Italiano formalizó el consultorio de Salud Ambiental con la intención de brindar respuesta a la demanda de pacientes que atribuyen síntomas y signos a la polución ambiental.
Logos problematicos, czyli problem z problemem
Authors: Bronk Andrzej , Majdański Stanisław , Walczak Monika
Published: October 2022

Monografia stanowi zwieńczenie intelektualnej przyjaźni i wieloletniej współpracy naukowej Andrzeja Bronka i Stanisława Majdańskiego, profesorów Wydziału Filozofii KUL, wspartych istotnie w fazie finalnej przez Monikę Walczak. Jej tematem jest kategoria problemu podstawowa dla każdego typu poznania. Na co dzień rzadko pytamy o sens używanych słów i odczuwamy potrzebę doprecyzowywania ich znaczeń. Odmieniany przez wiele przypadków „problem” należy do częstych wyrażeń języka potocznego i naukowego. Zrozumienie miejsca problemów w każdym typie konwersacji pozwala dostrzec istotne zróżnicowanie sytuacji badawczych i decyzyjnych w poszczególnych dziedzinach wiedzy teoretycznej i praktycznej (chociażby w sądownictwie). Mamy tu jednak do czynienia z „przedmiotem” niepoddającym się łatwej analizie, m.in. dlatego, że chodzi o wyrażenie wieloznaczne, niejasne i nieostre zarówno w użyciu potocznym, jak i naukowym. Z jednej strony wydaje się znajome, z drugiej, jak każde wyrażenie często i na różne sposoby używane (i nadużywane), podlega znaczeniowej inflacji oraz zakresowemu i treściowemu rozmyciu. Logicy i filozofowie poświęcili wprawdzie wiele prac samym pytaniom, ale o problemie, jeśli w ogóle, mowa jest tylko ubocznie. Rozczarowują słowniki i encyklopedie filozoficzne, w których rzadko spotykamy bardziej rozbudowane hasło problem czy nawet wzmiankę o nim w indeksie. Przedmiotem monografii jest głównie naukowe i filozoficzne użycie kategorii problemu, ale rozważania prowadzone są szeroko, by objęły inne obszary. Nie chodzi jednak o normowanie praktyki badawczej, lecz o zdanie sprawy z wielorakich sposobów funkcjonowania kategorii problemu. Istotny jest także teoretyczny i praktyczny pożytek z przeprowadzanych analiz, pozwalających lepiej zrozumieć naturę problemu i tak przyczynić się do jej bardziej świadomego użycia. Rozważania nawiązują do koncepcji erotetyki, wypracowanej przez szkołę lwowsko-warszawską, a tu do dystynkcji metodologicznych K. Ajdukiewicza. Akcentowane jest osadzenie rozważań w dokonaniach lubelskiego środowiska filozoficznego, zwłaszcza w pracach Stanisława Kamińskiego (1910–1986).
