Authors: Karim Mani Abdul , Venkatachalam Jonnadula
Published: March 2023

OBJECTIVES: To evaluate the feasibility and efficacy of a newly adapted IAME-CCT-MCI cognitive intervention for the elderly with Mild Cognitive Impairment (MCI).

METHODS: The first phase involved rehabilitation experts (N=7) for content evaluation. Followed by twelve elderly participants with MCI (N=12) were selected for rating the intervention. In phase two, Thirty-two (32) elderly participants were utilized to conduct a randomized pilot study using Single-group pretest-posttest design.

RESULTS: Experts agreed that each module was relevant to the intended target (3.87), effective in modifying the target (3.84), and appropriate for the elderly with MCI (3.87). The elderly participants stated that the intervention modules were useful (4), easy to use (3.36), and acceptable (4.08). Analysis of the paired t-test analysis revealed that the intervention program enhanced the cognitive and memory functions of the elderly.

CONCLUSIONS: The findings suggest that the intervention was feasible, acceptable, and user-friendly to the elderly and provided preliminary support for the efficacy of the IAME-CCT-MCI cognitive intervention.

Published: March 2023

Florida has many ecosystems that are thought of as especially important such as springs, coasts, dry prairies, and the Everglades. One of the ways importance is measured is through value. The term ecosystem services describes the benefits ecosystems and their components provide humans. This publication describes some of the ways to measure ecosystem services and explains how the different approaches to assess ecosystems might be selected, depending on what is most important to the user. This publication should help Extension and outreach agents, as well as agency personnel better understand ecosystem services values and explain them to the public. It should also help interested members of the public who wish to learn more about ecosystem services for themselves.

Authors: Qiu Jiangxiao , Zhao Hui , Bravo Lorna , Ryals Jessica
Published: March 2023

Urban agriculture has the potential to contribute to urban sustainability through its interactions with food, water, and energy (FEW) resource flows, and thus needs to be evaluated and analyzed through an integrative rather than a siloed approach. This publication provides an overview of the concept of FEW nexuses in the urban context and describes the role of urban agriculture and its sustainability implications for FEW nexuses and resources. Specific local case studies provide examples. This publication provides a holistic, interdisciplinary lens to understand the crucial role and sustainability implications of urban agriculture, currently gaining momentum in the global research and policy agenda. The fact sheet should be useful to urban and regional planners and policy-makers engaged in the development of urban agriculture, as well as to Extension agents seeking to communicate the sustainability implications of urban agriculture.

La producción lechera es una actividad de enorme prominencia no solo en Brasil sino en todo el planeta, ejerciendo una enorme influencia en la economía, generando empleos no solo en el área rural sino en toda la cadena de producción, ofreciendo leche y derivados que se encuentran entre los principales alimentos de la cadena alimentaria, ya que es rica en proteínas y vitaminas. Sin embargo, a pesar de que Brasil es uno de los mayores productores del mundo, la leche brasileña aún necesita estar más presente internacionalmente. Esta baja presencia en el extranjero se debe, entre otras razones, al alto costo de producción y su baja calidad. Sobre esta base, esta investigación tiene como objetivo relevar el panorama de la cadena de producción de leche en Brasil. El método de investigación se basa en una revisión de la literatura con carácter descriptivo y exploratorio. Como resultado, la investigación muestra la importancia que ha adquirido la actividad láctea en el país. Además, las políticas públicas que valoran el sector fomentan la producción de productos lácteos con calidad e inocuidad y crean las condiciones para que las tecnologías desarrolladas lleguen a los productores.
El profesor como sujeto fundador de un discurso
Authors: Assolini Filomena Elaine Paiva , Garrido Caio , Bartholomeu Josiane Aparecida de Paula
Published: March 2023

Fundar un discurso implica pensar por uno mismo y ser un autor no prohibido por una estructura previa de poder. Por lo tanto, este artículo adoptado como un ist central: ¿cómo influye la estructura de poder en la construcción del propio pensamiento, especialmente en la construcción de un discurso pedagógico por parte del maestro? Con el objetivo no sólo de buscar la respuesta a esta pregunta y entenderla, sino también, desde los conceptos de sujeto y autoría, pensar en cómo las lecturas y afiliaciones del discurso y el significado crean o impiden la existencia de un pensamiento propio y desligado de una mera estructura de poder. Por lo tanto, para la investigación, los campos teóricos de afiliación fueron el Análisis del Discurso (AD), la Teoría Socio-Histórica de la Alfabetización y el psicoanálisis freudo-lacaniano. Además, se realizó una encuesta con cerca de 35 profesores de asignaturas que imparten clases en escuelas públicas estatales y municipales de Ribeirão Preto y ciudades vecinas, que fueron entrevistados, arrojando declaraciones orales y escritas. Así, los resultados mostraron que a veces prevaleció la identificación del docente con un discurso sociopedagógico históricamente constituido, donde prevaleció la presencia de desagrado en las actividades, ya que fueron impulsadas por imposiciones institucionales, y a veces prevaleció la interpretación y producción de significados y (re)significados por parte del sujeto-profesor, autorizándose en sus dichos. Así, se encontró que el conocimiento y el derecho a la interpretación (a la lectura) no se comparte, sino que se distribuye social e históricamente de una manera no homogénea. Por lo tanto, dada la forma en que se administra institucionalmente la interpretación, la autoría se ve afectada por ella. Es decir, para poder ocupar el puesto de autor, es necesario tener el derecho y la posibilidad de ocupar diferentes lugares de interpretación, moverse por ellos y constituirse como intérprete. Y aún más, como intérprete-historizado.
CHAOS SEARCH IN FOURIER AMPLITUDE SENSITIVITY TEST
Authors: Koda Masato
Published: March 2023

Work in Artificial Intelligence (AI) often involves search algorithms. In many complicated problems, however, local search algorithms may fail to converge into global optimization and global search procedures are needed. In this paper, we investigate the Fourier Amplitude Sensitivity Test (FAST) as an example of a global sensitivity analysis tool for complex, non-linear dynamical systems. FAST was originally developed based on the Fourier series expansion of a model output and on the assumption that samples of model inputs are uniformly distributed in a high dimensional parameter space. In order to compute sensitivity indices, the parameter space needs to be searched utilizing an appropriate (space-filling) search curve. In FAST, search curves are defined through learning functions, selection of which will heavily affect the global searching capacity and computational efficiency. This paper explores the characterization of learning functions involved in FAST and derives the underlying dynamical relationships with chaos search, which can provide new learning algorithms. This contribution has proven the general link that exists between chaos search and FAST, which helps us exploit the ergodicity of chaos search in AI applications.
A MIXED INTEGER LINEAR PROGRAMMING MODEL FOR REAL-TIME TASK SCHEDULING IN MULTIPROCESSOR COMPUTER SYSTEM
Authors: Oluwadare Samuel Adeboyo , Akinnuli Basil Oluwafemi
Published: March 2023

There has been an upsurge in real-time multimedia applications in recent time. On a network, the ability of an average uniprocessor computer to handle such data may be limited due to the large size of such data. Also, there may be a high number of concurrent users who may want to retrieve data and the need to process them in real-time; and in continuous stream. This may lead to low quality service and deadline misses. The advent of multi-processor systems offers a more efficient way of processing multimedia data in real-time. With the development of appropriate scheduling algorithm, another challenge is the mode of assigning tasks in multi-processor systems. This calls for the use of an appropriate mathematical model that will take cognizance of the nature of variables involved. In this research work, a Mixed Integer Linear Programming Model (MILP) was developed to assign tasks in a multiprocessor system. The MILP model was used to assign tasks to multi-processor systems ranging between 5 and 10 homogenous processors. The result of the simulation runs shows that with the appropriate scheduling algorithm, a high success rate ratio and guaranteed number of deadlines met could be achieved.
IMPLEMENTATION AND VALIDATION OF AN ADAPTIVE FECMECHANISM FOR VIDEO TRANSMISSION
Authors: Ghazali Osman , Harun Nur Ziadah
Published: March 2023

This research focuses on investigating the FEC mechanism as an error recovery over a wireless network. The existing adaptive FEC mechanism faces a major drawback, which is the reduction of recovery performance by injecting too many excessive FEC packets into the network. Thus, this paper proposes the implementation of an enhanced adaptive FEC (EnAFEC) mechanism for video transmission together with its validation process. There are two propositions in the EnAFEC enhancement, which include block length adaptation and implementation, and suitable smoothing factor value determination. The EnAFEC adjusts the FEC packets based on the wireless network condition so that excessive FEC packets can be reduced. The proposed enhancement is implemented in a simulation environment using the NS-2 network simulation. The simulation results show that EnAFEC generates less FEC packets than the other types of adaptive FEC (EAFEC and Mend FEC). In addition, a validation phase is also conducted to verify that the proposed enhancement is functioning correctly, and represents a real network situation. In the validation phase, the results obtained from the simulation are compared to the outputs of the other adaptive FEC mechanisms. The validation results show that the mechanism is successfully implemented in NS2 since the number of packet loss falls under the overlapping confidence intervals.
WOMEN IN OPEN SOURCE SOFTWARE INNOVATION PROCESS: WHERE ARE THEY?
Authors: Mahmod Musyrifah , Md Dahalin Zulkhairi
Published: March 2023

The Open Source Software (OSS) Innovation process is no more a foreign face in the software development community as it is increasingly being used as a platform for modern software innovation both in the commercial and software research community. Although the concept of freedom is mostly prominent with the OSS innovation process, less than 2% of the contributors are women in this male dominated area. Minorities, including women, are often ignored in its process. This paper presents the case of lack of participation from women in the OSS innovation process. Lack of participation and contributions from women in OSS innovation creates an imbalanced population in the OSS based knowledge demography and an unbalanced proportion of gender distribution. Based on a comprehensive review, this paper aims to suggest a Constructivist-Technofeminist-OSS Innovation Process framework for understanding female contributions in OSS innovation, not only from a singular point of technical view, but also from social constructivist and feminist perspectives.
BALANCED CONTENT ALLOCATION SCHEME FOR PEERSERVICE AREA CDN ARCHITECTURE FOR IPTV SERVICES
Authors: Ahmad Gaber Suliman Mohamed , Sumari Putra , Budiarto Rahmat
Published: March 2023

One of the main problems in IPTV technology is how to manage the huge amount of multimedia contents efficiently to meet the demands of users especially for Video on Demand (VoD) services. Content Distribution Networks (CDN) are used to solve this problem but the problem of load imbalance among servers still exists due to the dynamic changes in contents and user interests in an IPTV environment. In the VoD context, many content storage management architecture models are proposed: single point, hierarchal, distributed, and service peer area architectures. In the this paper we choose peer-service area architecture for CDN to study the load imbalance problem and try to handle it by modifying peer-service area architecture and proposing a balanced content allocation scheme that solves the load imbalance problem by replicating the contents based on their popularity. Experimental results show that this proposed allocation scheme can maintain the load balancing among servers and avoid over/under utilization of servers.

Published: March 2023

Data grid is an infrastructure that manages huge amounts of data files, and provides intensive computational resources across geographically distributed collaboration. In order to speed up the data access and reduce bandwidth consumption, data grid replicates essential data in multiple locations. This paper studies the data replication strategy in data grid, taking into account the exponential growth/decay of data files and the dependency relationships between them. Simulation results (via OptorSim) show that the proposed strategy outperformed existing work in the measured metrics â€“ mean job execution time, effective network usage and average storage usage.

Authors: Osman Baharudin , Abas Azizi , Ghazali Osman , Harmoni Kamal
Published: March 2023

Anti-censorship software was originally developed to fight internet censorship in China. A anti-censorship software such as UltraSurf, Freegate, Gpass, GTunnel and FirePhoenix became popular with stubborn users who used the Internet for their own purposes and disobeyed the organizationâ€™s policies. Statistics show that Facebook, and YouTube are ranked as the most popular websites used by college students in Malaysia. Since they are widely used by users in the local area network to bypass firewall policies, they have become a threat to the LAN organization. Hence, it causes a problem for network administrators who manage internet utilisation and enforce internet policies. For an organisation, uncontrolled internet usage leads the open system to be vulnerably to viruses, backdoor, non-productivity activities and slow internet connections. Thus, this study proposes a strategy to filter and block traffic created by anti-censorship software in LAN. The method used in this project is the â€œdesign computer security experimentâ€. Therefore, this project will guide the network administrator to control internet utilisation, protect the organisationâ€™s LAN and carry out the implementation of the internal organizationâ€™s internet policies. As a result, this paper has proposed a strategy to block the UltraSurf anti-censorship software. The proposed strategy was tested in several public and private higher education institutions.

Published: March 2023

The easy access and flexibility provided by cloud computing have made various types of organizations use this technology as an alternative solution. However, the decision to use the cloud technology sometimes ignores the basic aspects related to the understanding of its compliance with the characteristics of the organization. Thus, many advantages of the adoption of the technology do not align with the needs. This paper discusses the requirements engineering of the alignment of the organizational characteristics and the cloud computing technology in order to create the adaptive ability to guide strategic-business driven organizations. The model proposed in this article is formulated based on three views: architectural, alignment, and adaptive, by employing the Goal-Oriented Requirements Engineering. As a case study, the model is applied to cloud computing for university. The architectural view can translate the environmental characteristics of organizations through goal decomposition into detailed needs. Meanwhile, the alignment view can meet the implementation, so the dynamic adaptive ability can be realized through the adaptivity view.The mechanism of our proposed model can cover the adaptation needs before the migration (pre-migration), during the migration, and after the migration (post-migration).
CONTROL OF BIPEDAL LOCOMOTION WITH A NEURAL OSCILLATOR-BASED BRAINâ€“COMPUTER INTERFACE
Authors: Ikeda Ryo , Horie Ryota
Published: March 2023

This study proposes a neural oscillator-based brainâ€“computer interface (BCI) that controls a bipedal neuromusculoskeletal (NMS) model by inputting electroencephalogram (EEG) signals. In this BCI system, while the bipedal NMS system realizes bipedal locomotion through internal entrainment among neural oscillators and a musculoskeletal system, the locomotion of the system is controlled via external entrainment of the neural oscillators to the external input of EEG signals. As the first step in developing the neural oscillator-based BCI controlling a bipedal NMS model, exploratory numerical simulations were conducted to investigate the behavior of the proposed BCI when sinusoidal waves and alpha waves were inputted. The following tendencies were observed: (a) inputting sinusoidal waves with small amplitudes and high frequencies did not affect the natural walking behavior of the bipedal NMS model that was generated by including only offset values in the external input, (b) inputting sinusoidal waves with small amplitudes and low frequencies disturbed and decelerated the walking behavior, (c) inputting sinusoidal waves with large amplitudes accelerated the walking behavior, (d) inputting sinusoidal waves with large amplitudes and a particular frequency changed walking behavior to running behavior, (e) changing the external input of alpha waves between an eyes-open condition and an eyes-closed condition successfully changed the walking behavior. The eyes-open condition led to faster walking compared with the eyes-closed condition.

Published: March 2023

Web caching plays a key role in delivering web items to end users in World Wide Web (WWW). On the other hand, cache size is considered as a limitation of web caching. Furthermore, retrieving the same media object from the origin server many times consumes the network bandwidth. Furthermore, full caching for media objects is not a practical solution and consumes cache storage in keeping few media objects because of its limited capacity. Moreover, traditional web caching policies such as Least Recently Used (LRU), Least Frequently Used (LFU), and Greedy Dual Size (GDS) suffer from caching pollution (i.e. media objects that are stored in the cache are not frequently visited which negatively affects on the performance of web proxy caching). In this work, intelligent cooperative web caching approaches based on J48 decision tree and NaÃ¯ve Bayes (NB) supervised machine learning algorithms are presented. The proposed approaches take the advantages of structured peer-to-peer systems where the contents of peersâ€™ caches are shared using Distributed Hash Table (DHT) in order to enhance the performance of the web caching policy. The performance of the proposed approaches is evaluated by running a trace-driven simulation on a dataset that is collected from IRCache network. The results demonstrate that the new proposed policies improve the performance of traditional web caching policies that are LRU, LFU, and GDS in terms of Hit Ratio (HR) and Byte Hit Ratio (BHR). Moreover, the results are compared to the most relevant and state-of-the-art web proxy caching policies.
MODELING RESERVOIR WATER RELEASE DECISION USING ADAPTIVE NEURO FUZZY INFERENCE SYSTEM
Authors: Abdul Mokhtar Suriyati , Wan Ishak Wan Hussain , Md Norwawi Norita
Published: March 2023

Reservoir water release decision is one of the critical actions in determining the quantity of water to be retained or released from the reservoir. Typically, the decision is influenced by the reservoir inflow that can be estimated based on the rainfall recorded at the reservoirâ€™s upstream areas. Since the rainfall is recorded at several different locations, the use of temporal pattern alone may not be appropriate. Hence, in this study a spatial temporal pattern was used to retain the spatial information of the rainfallâ€™s location. In addition, rainfall recorded at different locations may cause fuzziness in the data representation. Therefore, a hybrid computational intelligence approach, namely the Adaptive Neuro Fuzzy Inference System (ANFIS), was used to develop a reservoir water release decision model. ANFIS integrates both the neural network and fuzzy logic principles in order to deal with the fuzziness and complexity of the spatial temporal pattern of rainfall. In this study, the Timah Tasoh reservoir and rainfall from five upstream gauging stations were used as a case study. Two ANFIS models were developed and their performances were compared based on the lowest square error achieved from the simulation conducted. Both models utilized the spatial temporal pattern of the rainfall as input. The first model considered the current reservoir water level as an additional input, while the second model retained the existing input. The result indicated that the application of ANFIS could be used successfully for modeling reservoir water release decision. The first model with the additional input showed better performance with the lowest square error compared to the second model.

Authors: Ahmi Aidi , Mohamad Rosli
Published: March 2023

Websites become essential means for most universities to communicate, exchange of relevant information and enable transactions among their stakeholders. Therefore, website accessibility accessible website is crucial to students to ensure equal access to of the universityâ€™s information regardless of their physical disabilities and other possible limitations. This study reports the web accessibility of 20 Malaysian public universities based on AChecker and WAVE. The results suggest a relatively low level of compliance to the guidelines as specified in WCAG 2.0 and Section 508. Among the aspects that deserve immediate attention are the provision of text alternatives for any non-text contents, keyboard accessibility and colour contrast. Other concerns such as navigation, adaptability, input assistance, compatibility, empty link and empty heading can be further improved. Regardless of low conformance, most websites extensively integrated some of the accessibility features as set out by Section 508. Overall, this study offers meaningful insights, particularly to web developers for better compliance with the standards while designing their websites.

Published: March 2023

Purpose â€“ Smartphones have become part and parcel of life in the 21st century.  However, limited studies have examined the impact of mobile addiction and interpersonal relationship on academic behaviour among adolescents in higher education. Hence, this study was conducted to explore the relationship between these three variables in the Malaysian higher education context.   Methodology â€“ A descriptive correlational research design was employed to collect and analyse the data from a total of 150 young adults who responded to an online Google form distributed through a WhatsApp link. The items in the questionnaire were adapted from various doctorate studies. The data were analysed using descriptive and inferential statistics such as mean and standard deviation, correlation and multiple regression.   Findings â€“ The study found that adolescents in Higher Education in Malaysia have a moderate level of mobile addiction. The results also established that the three variables, namely mobile addiction, interpersonal relationship, and academic behaviour, were interrelated. The findings suggest that relationship status, interpersonal relationship and gender contributed to the variance in the academic behaviour of adolescents in higher education, with relationship status being the most significant. The study also found that smartphones do not affect the academic behaviour of adolescents.   Significance â€“ The findings provide valuable information to help facilitate the monitoring of mobile usage behaviour of adolescents in higher education.

Published: March 2023

The pressure dependence of the lattice and elastic constants of the binary precipitates γ-TiAl, DO22-Al3Ti and α2-Ti3Al are firstly investigated by using a ﬁrst-principles approach. The calculated results at 0 GPa and 0 K agree well with the existing experimental and other theoretical values. Using the density-functional perturbation theory (DFPT) under the quasiharmonic approximation (QHA), the temperature and pressure dependencies of the bulk modulus, the Gibbs free energy, the thermal expansion coefficient, as well as the heat capacity at constant pressure are investigated systematically in the ranges of 0–1000 K and 0–30 GPa.
FEM heat transfer modelling with tomography-based SiCf/SiC unit cell

Published: March 2023

Modern industry has become increasingly reliant on composite materials for a variety of applications, and the nuclear industry is no exception to this. Among the materials being researched as Enhanced Accident Tolerant Fuels, ceramic matrix composites such as SiC-fiber-reinforced SiC (SiCf/SiC) figure as some prime candidates due to their excellent high temperature performances. SiCf/SiC so far shows adequate nuclear, mechanical and chemical properties; still, the thermal properties need further investigation.

The thermal behavior of a material is an important factor for its performance as a nuclear fuel cladding, i.e. the first barrier encapsulating the fuel pellets. Many features determine the resulting properties of composite materials, such as matrix and fiber reinforcement properties and orientation, void fraction, and pore morphology. This study establishes a methodology to study the physical properties of composite materials and applies it to SiCf/SiC. A FEM model is used to characterize the thermal properties of a fundamental SiCf/SiC element, referred to as a �unit cell�, with the objective of accurately predicting the thermal properties of this complex class of materials where experimental data is often difficult to obtain. The unit cell is built based on data acquired with high-resolution tomographic microscopy performed at the TOMCAT beamline of the Swiss Light Source.

By using phase-retrieval prior to tomographic reconstruction, the pores, fibers and matrix that compose the material can be distinguished in the data analysis. The separated information is processed to obtain geometrical information about the individual pores and fibers, which is then used to parametrize them as cylindrical objects. This allows constructing a FEM model of a cubic unit cell that is used to extract the effective thermal properties of SiCf/SiC. The analysis scheme includes steady-state and dynamic thermal transport simulations, which yield directional effective thermal conductivity and diffusivity values, respectively. Both modes of analysis show isotropic thermal conductivity values in the range of 71 W/m/K at room temperature, more than three times that of currently employed nuclear cladding materials.

Combining these results with the data on the larger structural features of the material will lead to realistic results on the macroscopic thermal properties.
Electronic, elastic and pressure-induced phase transitions of tetragonal NaBH4 under high pressure
Authors: Yamçiçier Çağatay
Published: March 2023

In this study; the structural, electronic and mechanical properties of sodium borohydride (NaBH4) compound were studied under high hydrostatic pressure from 0 to 300 GPa using the generalized gradient approach (GGA) within the framework of density functional theory (DFT). In the study, the NaBH4 compound transformed from the tetragonal structure with the space group P42 /nmc to the triclinic structure with the space group with the effect of gradually increasing pressure. Enthalpy and total energy calculations were performed to observe the agreement of the study with the experimental results. As a result of the calculations, it was concluded that a phase transition of the NaBH4 compound occurred at approximately 22.6 GPa from the tetragonal structure to the triclinic structure. In addition, the electronic properties of the NaBH4 compound were investigated and 6.22 and 4.95 eV band gaps were obtained for the P42 /nmc and phases, respectively.
Study of size effect on thermophysical properties of metallic nanosolids
Authors: Goyal Monika
Published: March 2023

In the present study, a phenomenological model based on thermodynamic variables is developed to study the thermophysical properties of nanomaterials with respect to size in nanoscale. The model input parameters are lattice packing fraction depending on crystal structure and atomic diameter of nanosolid. The shape parameter is incorporated in the model to study the variation in physical properties of metallic nanosolids with shape. The size and shape effect on melting temperature , Debye temperature θ, Specific heat capacity , thermal conductivity and electrical conductivity σ is studied in metallic nanosolids. It is observed from the results obtained that both melting temperature and Debye temperature get reduced with reduction in size of nanosolid. Also Thermal conductivity and electrical conductivity in nanosolids decrease as size reduces. This is due to the increase in the number of surface atoms with size reduction and pronounced quantum confinement in nanomaterials. Also, the drastic change in number of surface atoms with the change in shape of the nanomaterial of same size brings about change in its thermophysical properties. The present model results are found consistent with the available experimental and simulated results of previous workers and may be useful for experimental researchers exploring the physical properties of nanomaterials.

High entropy carbides (HECs) are a promising new class of ultra-high temperature ceramics that could provide novel material solutions for leading edges of hypersonic vehicles, which can reach temperatures > 3,500 �C and experience extreme thermal gradients. Although the mechanical and thermal properties of HECs have been studied extensively at room temperature, few works have examined HEC properties at high temperatures or considered these materials� responses to thermal shock. In this work, we measure the thermal conductivity of a five-cation HEC up to 1200 �C. We find that thermal conductivity increases with temperature, consistent with trends demonstrated in single-metal carbides. We also measure thermal conductivity of an HEC deposited with varying CH4 flow rate, and find that although thermal conductivity is reduced when carbon content surpasses stoichiometric concentrations, the films all exhibited the same temperature dependent trends regardless of carbon content. To compare the thermal shock resistance of HECs with a refractory carbide, we conduct pulsed laser ablation measurements to determine the fluence threshold the HECs can withstand before damaging. We find that this metric for the average bond strength trends with the theoretical hardness of the HECs as expected.

Systematical experimental data on density, molar volume and the surface tension, measured in electromagnetic levitation, has been summarized for the liquid Ti-V system. The optical dilatometry method as well as the oscillating drop technique have been employed to investigate the temperature- and compositional dependence. A linear decrease in density and surface tension with increasing temperature has been observed for all investigated compositions. Pure Vanadium shows hereby the highest density and surface tension while pure titanium shows the lowest density and surface tension respectively. Therefore, the density and surface tension decrease with increasing titanium content, however not linear. Since no excess quantities were available, simple models could be employed to cover the complete liquid Ti-V system. Experimental data as well as the corresponding linear fits are presented.

Hypocenter estimation was carried out in several local earthquake events in the upper arm of Sulawesi Island. The process is carried out by utilizing P and S wave arrival time data obtained through automated phase picking. The Wadati diagram was used to test the feasibility of the data and HYPOINVERSE was used to estimate the hypocenter. Vp/Vs ratio shows varied results and RMS shows poor data picking. These results have an impact on RMS values which are quite high in the estimation of the hypocenter. There was an inverse comparison of the results when viewed through the RMS value between Wadati and HYPOINVERSE. Picking data improvements need to be done in order to get a better estimate.

Apesar do Brasil ser um dos países com maior número de evidências científicas sobre a reabilitação por meio do exercício físico na doença renal crônica (DRC), o profissional do exercício físico ainda não é um membro das equipes assistenciais em nefrologia. Nesse sentido, compartilhamos a opinião de pesquisadores e profissionais atuantes na área da reabilitação por meio do exercício físico na DRC para conscientizar as entidades de classe e as equipes multidisciplinares assistenciais da área da nefrologia, mostrando os avanços e a importância da reabilitação na DRC no Brasil e no mundo. Além disso, criamos o Grupo Brasileiro de Reabilitação em Nefrologia (GBREN) com o objetivo de estabelecer e fortalecer a cultura nacional do exercício físico na DRC. Assim, acreditamos que esse cenário possa ser revertido e estaremos no front, na expectativa de que, num futuro breve, a reabilitação por meio do exercício físico venha a ser uma realidade clínica no tratamento de todas as pessoas com DRC.
Replacing bank money with base money: Lessons for CBDCs from the ending of private banknotes in Sweden
Authors: Ögren Anders
Published: March 2023

A number of central banks have started to investigate the possibility of issuing so-called Central Bank Digital Currencies (CBDCs). The aim may be to compete with cryptocurrencies of different kinds but also to replace digital commercial bank money with central bank issued digital money, i.e. replacing bank money with central bank-issued basemoney. In this paper we study a similar experiment when the Swedish central bank, the Riksbank, in 1903 replaced private banknotes with their own notes. The result of this policy was a massive increase in commercial bank credit due to the increase in base money, spurring the ongoing boom even further. A boom that worsened the 1907 crisis. The result is thus questioning the notion that increased monetary issuance by a monetary authority to replace other financial assets as private money or cryptoassets should lead to increased financial stability – as, in fact, it led to the opposite.

Key Performance Indicators (KPIs) help measure objectives critical to business sustainability. This research takes place in a toy factory’s injection moulding department that has yet to develop indicators for subcontractor performance. Poor subcontractor performance significantly impacts the injection moulding production. In the last three months, the delivered quantity exceeded the target by 27%, delivery time consistency is only 78%, there were 1.31% rejects, and inventory accuracy and material efficiency were 81% and 93% respectively. The objective of the study is to determine the KPI and develop an evaluation procedure for the injection moulding supplier and select the best supplier. Multi-criteria decision-making, i.e., weighted sum method, was used. Five employees were involved in determining the criteria weights. The evaluation was based on each supplier’s performance. A written KPI for the company's subcontractor and performance evaluation procedures were developed. There were six subcontractors of which subcontractor H received the highest score (78.42) and subcontractor G received the lowest score (69.42). The subcontractor performance needs to be improved in the future. In the interest of the company’s sustainability, it is recommended that this subcontractor performance evaluation be institutionalised to support subcontractor performance. Successful subcontractors support the business performance.
