Felix Klein (1849-1925): Symbiosis of History, Teaching, and Culture
Authors: Tobies Renate
Published: October 2023

Based on recent studies, it is possible to explain the hitherto little-noticed link between the fields of history, teaching and culture in Klein’s teaching and research projects and the international impact associated with them. This symbiosis can be seen as part of Klein’s goal to reform mathematics education and bring mathematics into the consciousness of broad circles as a necessary component of culture.
A Re-examination of the Nineteenth Century French Influence on American Mathematics Education through Textbook Author Charles Davies
Authors: Zelbo Sian
Published: October 2023

Charles Davies was a prolific and influential nineteenth-century author of mathematics textbooks. Davies’s 1835 adaptation of Bourdon’s Élémens d’Algèbre is of particular interest because it forms part of a larger story about French influence on American mathematics education by way of the United States Military Academy at West Point. Prior studies have argued that French-American influence was undercut by the tendency of authors to alter the French analytic style of pedagogy for American audiences. This study adds to that line of research by giving more evidence of how this particular book originated and how the content was altered. It shows that Davies took credit for the translation of his subordinate, Edward Ross, and then simplified the book by removing modern mathematical concepts. Rather than spreading novel French ideas about mathematics, Davies’s 1835 algebra book and its many subsequent editions likely reinforced the status quo of American mathematics education for decades.

Authors: Zwaneveld Bert , De Bock Dirk
Published: October 2023

Piet Vredenduin (1909–1996) played a prominent role in the Dutch mathematics education community during the second half of the twentieth century: mathematics teacher, mathematics researcher which led him to a dissertation on Fraenkel’s Mengenlehre applied to number theory, author of mathematics textbooks for almost all sections of the secondary mathematics curriculum, mathematics teachers’ educator, participant in two innovating projects: teaching history of mathematics, and statistics and probability theory in secondary education, contributor and editor of the journal of the Dutch association of mathematics teachers. Last but not least, he played an important role in the implementation of the ideas as discussed at “Royaumont” (“New Math”). These are his main activities inside the Netherlands. Internationally we have to mention his role as a trait d’union, “a liaison officer”, between the Dutch and the Flemish communities of mathematics teachers: representing the board of the Dutch mathematics teachers association on many occasions in Flanders, contributing articles to the journal of the Flemish mathematics teachers’ association, informing the Dutch mathematics teachers about the developments in Flanders, and the Flemish teachers about the developments in the Netherlands, especially about the implementation of the recommendations of “Royaumont”.

Published: October 2023

The paper describes the design and implementation of a 14-bit differential Digital-to-Analogue Converter (DAC) based on the Silterra 0.18µm Complementary Metal-Oxide-Semiconductor (CMOS) process to be established in a Successive Approximation Register (SAR) Analogue-to-Digital Converter (ADC) for the purpose of high-resolution, high accuracy and low power applications. The proposed differential DAC aims to eliminate the issue of stringent matching requirements imposed on high-resolution DACs while leveraging both linearity performance and power consumption parameters at a balanced point. The overall differential circuit consists of two parallel single-ended DACs that utilize a 4-bit Capacitor DAC (CDAC) and 10-bit Resistor DAC (RDAC) on each end, thereby establishing a hybrid-based architecture. Furthermore, the authors illustrate the proposed switching procedures applied to the sub-DAC circuits to ensure a low-power design is established. The new method effectiveness evaluation is confirmed by detailed transient simulations implemented on the DAC where the circuit performs the required conversions at a maximum conversion frequency of 2.5 MS/s with a peak power consumption of 0.1496mW for the standard voltage supply of 2.1V. Meanwhile, the schematic and post-layout simulations performed on the DAC registers peak DNL errors of -0.1612 and -0.8272, respectively. New research results depict performance improvements in terms of resolution and power consumption which facilitates the DAC implementation in contemporary electronic devices such as microcontroller peripherals and audio amplification devices. The overall deigned circuit is capable of achieving the desired 14-bit digital-to-analogue conversions under the CMOS 0.18µm technology, proving the DAC’s high-resolution efficacy.

Published: October 2023

Ship recycling in Malaysia is an unknown business as no dedicated ship recycling yard is currently operated in this country. Most Malaysian shipowners send their end-of-life (EOL) ships to prominent ship recycling yards in Pakistan, India, and China, which are key players in the global ship recycling industry. Due to various factors, establishing a proper ship recycling facility for Malaysia is challenging. One issue that arises is the ability of Malaysian yards to offer competitive EOL ship prices, which can be achieved by increasing the revenue or lowering the ship recycling process costs. It will allow Malaysian recycling players to offer a high price to ship owners and attract them to recycle their ships locally. This paper studies the potential of an integrated ship recycling facility for a Malaysian shipyard. A medium size shipyard situated at Chukai, Terengganu, was selected as a case study. The facility analysis was performed to determine share resources, and a revised layout was proposed. The prospect of ship recycling facility integration in Malaysian shipyards was discussed and summarised. The result analysis signifies that the shipyard facility can be adequately shared for ship recycling activity, and no major change is required in the overall shipyard layout. Lastly, the findings suggest that an integrated ship recycling facility is feasible for a Malaysian shipyard.

The Islamic inheritance system is typically explained through the concepts of wasiat (will), hibah, and faraid. In Islam, there is no limit on transferring property during a person's lifetime, but the distribution of inheritance upon death is subject to the rules of faraid and will. The delay in claiming inheritance rights for many Muslim families can lead to the accumulation of unclaimed estates and frozen assets that cannot be distributed to eligible heirs. This study aims to identify the challenges and issues with the traditional methods of inheritance distribution and propose improvements for the existing Ancestry Platform for Islamic Family Inheritance in Malaysia This study was designed as a qualitative approach that consists of five stages, which are Planning, Research Design, Data Collection, Data Analysis, and Documentation. This research has adopted Technology-Organization-Environment (TOE) Framework as part of the research scope and semi-structured interviews were conducted with the representatives from the Selangor Islamic Religious Council (MAIS) to identify the root cause of the inheritance distribution problem. The data collected was analysed using the Content Analysis method. This paper will propose the inclusion of documentation collections and family tree features as elements of the Ancestry Platform. These improvements could be useful for future developers or institutions looking to implement the platform.

Results have shown that the diffuser length impacts are largely independent results-wise and show no correlation, however, more data would be needed to form a conclusive statement. From this study, miniature models could be fabricated for the purpose of further testing. For instance, future studies could conduct an experimental approach to attain data that is as close to real-world applications as possible. This will be vital for the industrial application.

Filtered Cyclic Prefix Orthogonal Frequency Division Multiplexing (F-CPOFDM) is a 5G multicarrier waveform that enables high data rates and spectrum efficiency improvements. The primary drawback of F-CPOFDM is that it has a high peak to average power ratio (PAPR), which is a characteristic of all multicarrier modulation techniques. This paper shows the study of the application on Group Codeword Shift (GCS) approach to reduce the peak to average power ratio (PAPR) in a Filtered- CPOFDM system in this article. Additionally, this paper also compared the results of peak to average power ratio (PAPR) reduction with low complexity in Filtered-CPOFDM using a Group Codeword Shift (GCS) approach, Selective Codeword Shift (SCS), and Conventional CPOFDM. The simulation results indicate that the Group Codeword Shift (GCS) approach reduces peak PAPR by 45.95 percent when compared to conventional Filtered-CPOFDM, 26.13 percent when compared to the Selective Codeword Shift (SCS) method and 22.53 percent when compared to the Median Codeword Shift (MCS) method.

Malaysia is a fortunate country graced by abundant sunlight, potentially having success in the application of photovoltaic (PV) powered greenhouses to safeguard food security. This research seeks to develop a design basis for PV greenhouse suitable for application in Malaysia. The motivation behind this research arises from the fact that while there have been studies on the application of PV greenhouses globally, most of them have focused on Europe, the Mediterranean, and Japan. The research will include two experimentalprototypes and one control prototype, all featuring identical mono-span roof PV greenhouses with a 15° tilt angle and E-W orientation which has been determined based on literature review. For stage 1 of the research, the prototypes will differ in terms ofthe PV array arrangements on the roof; whereas in stage 2, PV panels fitted with V-Trough Solar Concentrators will be utilized instead of ordinary PV panels. By filling the research gap by exploring the potential of PV greenhouses in Malaysia, the outcomeof this research will contribute to the development of a design basis for PV greenhouses in Malaysia, revolutionising photovoltaic-powered modern agricultural technology.

Authors: Echeverri Luz Fanny
Published: October 2023

La medición de las variables que determinan la calidad del café son el punto de partida para la generación de recomendaciones técnicas que apoyen al caficultor en la toma de decisiones que conllevan al mejoramiento de la calidad en las etapas poscosecha que se realizan en la finca. Los resultados que se mostrarán en este seminario hacen parte de las investigaciones del Sistema General de Regalías del Cesar, cuyo objetivo principal es el de mejorar la calidad sensorial a partir de las particularidades que ofrece el territorio. Inicialmente se planteó la necesidad de realizar un diagnóstico de la calidad del café producido por 1.529 caficultores distribuidos en los 12 municipios y beneficiarios del proyecto durante la cosecha (2021–2022). Con base en los resultados obtenidos, se generaron las recomendaciones de buenas prácticas y controles durante el procesamiento del café vía húmeda, se priorizaron las nivelaciones tecnológicas y se planearon las jornadas de sensibilización a los caficultores. El impacto en la mejora de la calidad del café en el departamento del Cesar fue evaluado durante una segunda cosecha (2022–2023).
Elkövető és/vagy áldozat? Az emberkereskedelem áldozatai által kényszer/fenyegetés hatására elkövetett jogellenes cselekményekről

Aim: The complex phenomenon of trafficking in human beings includes not only sexual and labour exploitation but also so-called ‘other trafficking’. Most international and national research focuses on the characteristics of sexual exploitation, but it should be noted that in recent years there have also been publications on labour exploitation. Other forms of exploitation, in particular exploitation linked to unlawful acts, are discussed below. The acts committed by victims of trafficking may be not only criminal offences, but also non-criminal offences and other acts (tax, labour). What these crimes have in common is that in most cases these offenders would not have committed them voluntarily, but were coerced by their exploiters, by force and/or threats. These acts are discussed from a criminological perspective, referring to the fact that the substantive and procedural aspects of criminal law are assessed on a case-by-case basis in criminal proceedings.Methodology: The following is a partial report of the results of the research carried out at the National Institute of Criminology in 2023, summarising the first results of the review of national and international literature, professional interviews and the analysis of the documents after the presentation of a case.Findings: The offences committed by victims of trafficking, typically under duress, are similar to international characteristics: in addition to offences against property and drug-related ones, however, others should also be mentioned: illicit prostitution, begging and various other offences.Value: There has been little literature on the offences committed by victims of trafficking in human beings in the country, and this gap is being filled by drawing attention to the importance of providing further training for law enforcement officials.

Aim: To demonstrate, through a demonstration of the complexity of ecosystem risks, that the criminal consequences of climate change require a specific criminological and criminal justice approach.Methodology: The thematic systematisation of new findings and conclusions produced by the co-disciplines in the scientific literature at a speed different from traditional publishing patterns. This will involve testing and applying artificial intelligence-enabled source literature retrieval techniques.Findings: The consequences of climate change are reaching the forensic sciences. It is important to define the hierarchy of damages, to establish the mutual effects of the consequences of damages, the direct and indirect consequences of damages, the present and expected future severity of the consequences suffered by direct and indirect victims. These phenomena are interlinked not only hierarchically but also in a networked way. If environmental protection is to be more effective than it is at present, moral, political and legal responsibilities need to be grouped and differentiated as described above.Value: To demonstrate that effective criminal justice action against ecocide crimes can only be achieved through a systems approach to globally manifested harms.
The Origin of Power-law Spectra in Relativistic Magnetic Reconnection
Authors: Zhang Hao , Sironi Lorenzo , Giannios Dimitrios , Petropoulou Maria
Published: October 2023

Magnetic reconnection is often invoked as a source of high-energy particles, and in relativistic astrophysical systems it is regarded as a prime candidate for powering fast and bright flares. We present a novel analytical model—supported and benchmarked with large-scale three-dimensional kinetic particle-in-cell simulations in electron–positron plasmas—that elucidates the physics governing the generation of power-law energy spectra in relativistic reconnection. Particles with Lorentz factor γ ≳ 3σ (here, σ is the magnetization) gain most of their energy in the inflow region, while meandering between the two sides of the reconnection layer. Their acceleration time is

From climate change to AMR: understanding environmental-human health issues in a One Health framework
Authors: Reid Thomas , Broadbent Jordyn
Published: October 2023

As the impacts of climate change intensify, our interconnectedness to the environment around us seems ever more apparent. Changing terrestrial landscapes impact adjacent aquatic ecosystems, as the terrestrial-aquatic continuum experiences the ever-pressing stresses of anthropogenic activity. In the Canadian Arctic, ancient carbon stores and contaminants such as methylmercury are emerging as permafrost thaw accelerates, changing their biogeochemical nature, impacting local communities and threatening ecological health in ways still yet to be fully understood. Awakening microorganisms in these once frozen grounds are all too eager to get to work, as scientists continue to try to understand how, where, and why climate change is impacting aquatic ecosystems across Canada. Increasing aquatic nutrient loads and chemical/biological contaminants adjacent to urban and agricultural lands also impact both ecosystem and ultimately human health. In the shadow of a global pandemic, the need to understand how environmental-human interactions impact human health is ever pressing, requiring the collective expertise of researchers across the environmental-human health landscape. Antimicrobial resistance (AMR), despite being a natural evolutionary mechanism for microbial survival in the environment, has been increasing in presence and prevalence in healthcare systems worldwide, resulting in drug-resistant infections that can be fatal. As such, there is a need to understand AMR in both its natural state within the environmental microbial biosphere, alongside those places (i.e., agricultural lands, wastewater treatment outflows etc.) where humans have introduced co-selective agents such as metals, antibiotic residues and other compounds that can further facilitate and even promote resistance activity in the natural environment (Fig. 1). This connection between the human health landscape and the environment around us is a vital part of understanding the risks of both climate change and AMR, requiring an integrated and collaborative One Health approach across disciplines. Here we present research associated with our Genomics Research and Development Initiative programs using novel genomics tools and large-scale laboratory simulations to better understand the impacts of climate change and AMR in a multi-disciplinary environmental context. This work helps fullfil the need to understand the dynamics of these two global threats in an trans-disciplinary nature, drawing on the expertise of environmental microbiologists, hydrologists, bioinformaticians, and water quality experts, in tandem with public health and infectious disease experts to better understand how these threats will evolve as our planet tries to adapt to the complex stressors of the Anthropocene.
