The Effect of screen time on Children’s Behaviour
Authors: Al Naima Mohammed
Published: October 2023

As more of their leisure time is spent with screens such as iPhones, tablets, computer games, and television, parents, health experts, and educators are concerned about the impact of screen time on children’s well-being. Excessive screen usage has a negative impact on the verbal, emotional, and physical growth of children. Because children and teenagers are naturally drawn to screens, the aim is to teach them how to use them responsibly. Screens may help promote self-esteem and give numerous chances for learning and growth when used with good screen objectives and abilities. Children, especially those above the age of three, respond to interactive programming that is entertaining, suited to them, and stimulates imitation or participation. Dynamic video games may encourage light-to-moderate or acceptable physical exercise in the near future. Families and child care providers may include more physical activity into daily routines by using fun, age-appropriate exercise (e.g., yoga or dance) and fitness apps or videogames. As a result of these concerns, parents are being advised to limit their children’s screen time on a daily basis, with particular time constraints for children and a general guideline to minimize screen time in teenagers. Key words: screen time, children's behaviour

The transportation sector stands at the forefront of global challenges, where its significant contribution to greenhouse gas emissions and air pollution has become an urgent matter demanding immediate attention. For addressing these compelling concerns and leading the automotive industry toward a sustainable future, it is, therefore, imperative to explore the realm of alternative fuel that can effectively mitigate the environmental impact of automobiles. Methanol, a renewable alternative fuel, has gathered quite an attention due to its potential to be used as a wonderful alternative to neat gasoline in spark ignition engines. However, there are some core challenges that must be addressed to utilize methanol on a commercial scale in the transport sector. These core challenges include cold start issues, enhanced NOx emissions, 100% methanol utilization, transportation concerns and lubricant oil deterioration. In this chapter, these challenges along with their potential solutions have been discussed in detail. Moreover, different techniques such as artificial neural network and response surface methodology have been discussed to predict and optimize the usage of methanol in SI engines. The adoption of methanol, as an alternative to gasoline, will help us achieve some important sustainable development goals, thus fulfilling the promise of a sustainable future for the upcoming world.

Published: October 2023

Biofuel offers an alternative energy source to meet the energy demands of a growing population of 8 billion while minimizing environmental impact. Globally, around 3000 petajoules of biofuel are produced, diversifying energy sources from conventional to renewable. Corn, rich in starch that can be converted into ethanol, is widely used in biofuel production. Corn-based biofuels are popular due to their potential to reduce greenhouse gas emissions, their biodegradability, and clean ignition, enhancing energy security. While the current state of corn as a biofuel source appears promising, increasing production requires breeding strategies like varietal crossing and cultivar selection to enhance biomass and starch content. Better agronomic practices and extension strategies are also necessary to improve yield and promote adoption among farmers. Using maize as a feedstock for biofuel production can boost the agricultural industry, create jobs in farming, processing, and transportation, and reduce reliance on foreign oil while preserving foreign exchange reserves. Technological advancements, viz., cellulosic ethanol production, have further expanded the potential use of corn for biofuels due to its abundance and convenience. However, the future of corn-based biofuels is uncertain. Therefore, ongoing innovation, exploration of alternative feedstocks, and cutting-edge technologies are necessary to overcome challenges.
Millimeter wave band reconfigurable circuits (from 30 to above 100 GHz) in BiCMOS-MEMS technology
Authors:   , Heredia Vega Julio César
Published: October 2023

Nowadays, there has been an increased use of mobile devices and growth in the need for information, and because of this, wireless systems with higher data rates and wider bandwidths are demanded every year. Additionally, multi-applications systems need to operate at several frequency bands, which brings the need for compact frequency-reconfigurable devices.
In order to offer solutions for the demands mentioned above, in this Thesis, compact frequency-reconfigurable low-noise amplifiers (LNAs) using RF-MEMS and HBT based switches for frequencies above 100 GHz are presented for the first time. Multimodal coupled microstrip and three-line microstrip (TLM) structures are implemented in the amplifier matching networks to achieve more-compact designs.

To demonstrate the potentialities of the TLM structures, a novel compact multimodal TLM impedance tuner is presented. It features a Smith-chart impedance coverage of 70% in a large frequency bandwidth (1.4 to 3.2 GHz). The impedance tuner uses variable capacitors implemented with varactors to create asymmetries in the structure and interactions among the three-line microstrip modes. This results in an increase of the equivalent electrical size of the circuit thus reducing the overall physical size of the impedance tuner.

Three frequency-reconfigurable D-band compact BiCMOS LNAs have been designed. The three designs consist of two cascode stages and were fabricated using a 0.13 µm SiGe:C BiCMOS process which includes an embedded RF-MEMS switch module. The first and second LNA designs operate at 125/140 GHz, while the third design operates at 125/143 GHz. The area of the designs is minimized by using only one RF-MEMS switch to select the frequency band and multimodal structures (a coupled microstrip structure and a TLM structure in the input matching networks of the first and third design respectively). A systematic design method to obtain balanced gain and noise figure for both frequency states is presented.

An even more compact 120/140 GHz LNA design is accomplished by using an HBT-based switch instead of a RF-MEMS switch. It was fabricated with the same 0.13 µm SiGe:C BiCMOS process and using the same multimodal TLM structure in the input matching network as the third design mentioned above.

The measurements of all the LNAs are in good agreement with the obtained simulations thus validating all the circuit designs and the systematic design method.

A Bayesian approach to robust identification: application to fault detection
Authors:   , Fernández Canti Rosa Ma.
Published: October 2023

In the Control Engineering field, the so-called Robust Identification techniques deal with the problem of obtaining not only a nominal model of the plant, but also an estimate of the uncertainty associated to the nominal model. Such model of uncertainty is typically characterized as a region in the parameter space or as an uncertainty band around the frequency response of the nominal model.

Uncertainty models have been widely used in the design of robust controllers and, recently, their use in model-based fault detection procedures is increasing. In this later case, consistency between new measurements and the uncertainty region is checked. When an inconsistency is found, the existence of a fault is decided.

There exist two main approaches to the modeling of model uncertainty: the deterministic/worst case methods and the stochastic/probabilistic methods. At present, there are a number of different methods, e.g., model error modeling, set-membership identification and non-stationary stochastic embedding. In this dissertation we summarize the main procedures and illustrate their results by means of several examples of the literature.

As contribution we propose a Bayesian methodology to solve the robust identification problem. The approach is highly unifying since many robust identification techniques can be interpreted as particular cases of the Bayesian framework. Also, the methodology can deal with non-linear structures such as the ones derived from the use of observers. The obtained Bayesian uncertainty models are used to detect faults in a quadruple-tank process and in a three-bladed wind turbine.
An analysis of two-phase flows in conditions relevant to microgravity
Authors:   , Arias Calderón Santiago
Published: October 2023

Promising technological applications of two-phase flows in space have captured the increasing interest of the space sector, provoking a strong demand for more fundamental knowledge. Great efforts have been made in recent decades to study the behavior of two-phase flows in low-gravity environments, which is expected to be different than the behavior observed in the presence of gravitational forces. Nevertheless, many phenomena are still poorly understood. The development of any of these new technologies demands a better knowledge of two-phase flows.
In this manuscript we address questions regarding the generation of gas-liquid flows and their behavior in conditions relevant for a microgravity environment. In particular, we focus on an air-water mixture formed in a capillary T-junction. To this end, an experimental setup has been designed to accurately control both gas and liquid flow rates. We performed a quantitative characterization on ground of the T-junction, whose operation is robust to changes in gravity level. Its main performance is the generation of bubbles at a regular frequency with small size dispersion. We obtained two working
regimes of the T-junction and identified the crossover region between them. Bubble, slug, churn and annular flow regimes have been observed during the experiments and a flow pattern map has been plotted. We present an experimental study on the bubble-slug transition in microgravity-related conditions. In addition, we address questions regarding the existence of a critical void fraction in order for the bubble-slug transition to occur.
The gas-liquid flow has been characterized by measuring the bubble generation frequency as well as the bubble and liquid slug sizes. Since bubble dynamics is also expected to be different in the absence of buoyancy, the bubble velocity has also been studied. The mean void fraction appears as one relevant parameter that allows for the prediction of frequency, bubble velocity, and lengths. We propose curves obtained empirically for the behavior of generation frequency, the bubble velocity and the lengths. The dependence of the frequency on the Strouhal dimensionless number has been analyzed.
A numerical study of the formation of mini-bubbles in a 2D T-junction by means of the fluid dynamics numerical code JADIM is also presented. Simulations were carried out for different flow conditions, giving rise to results on the bubble generation frequency, bubble velocity, void fraction and characteristic lengths. Numerical results have been then compared with experimental data.
Reconfigurable pixel antennas for communications
Authors:   , Rodrigo López Daniel
Published: October 2023

The explosive growth of wireless communications has brought new requirements in terms of compactness, mobility and multi-functionality that pushes antenna research. In this context, recon gurable antennas have gained a lot of attention due to their ability to adjust dynamically their frequency and radiation properties, providing multiple functionalities and being able to adapt themselves to a changing environment.
A pixel antenna is a particular type of recon gurable antenna composed of a grid of metallic patches interconnected by RF-switches which can dynamically reshape its active surface. This capability provides pixel antennas with a recon guration level much higher than in other recon gurable architectures. Despite the outstanding recon guration capabilities of pixel antennas, there are important practical issues related to the performance-complexity balance that must be addressed before they can be implemented in commercial systems. This doctoral work focuses on the minimization of the pixel antenna complexity while maximizing its recon guration capabilities, contributing to the development of pixel antennas from a conceptual structure towards a practical recon gurable antenna architecture.
First, the conceptualization of novel pixel geometries is addressed. It is shown that antenna complexity can be signi cantly reduced by using multiple-sized pixels. This multi-size technique allows to design pixel antennas with a number of switches one order of magnitude lower than in common pixel structures, while preserving high multiparameter recon gurability. A new conceptual architecture where the pixel surface
acts as a parasitic layer is also proposed. The parasitic nature of the pixel layer leads to important advantages regarding the switch biasing and integration possibilities.
Secondly, new pixel recon guration technologies are explored. After investigating the capabilities of semiconductors and RF-MEMS switches, micro uidic technology is proposed as a new technology to create and remove liquid metal pixels rather than interconnecting them.
Thirdly, the full multi-parameter recon guration capabilities of pixel antennas is explored, which contrasts with the partial explorations available in the literature. The maximum achievable recon guration ranges (frequency range, beam-steering angular range and polarization modes) as well as the linkage between the di erent parameter under recon guration are studied.
Finally, the performance of recon gurable antennas in beam-steering applications is analyzed. Figures-of-merit are derived to quantify radiation pattern recon gurability, enabling the evaluation of the performance of recon gurable antennas, pixel antennas and recon guration algorithms.
Beamforming design and power control for spectrum sharing systems
Authors:   , Vázquez Oliver Miguel Ángel
Published: October 2023

In order to provide wireless services for the current demand of high data rate mobile applications, more spectrally efficient systems are needed. As a matter of fact, the current wireless systems are limited by a frequency splitting spectrum management which in one hand minimizes the multiuser interference but; on the other hand, it precludes the use of wider bandwidth signals. As a more aggressive frequency reuse is targeted (ideally, all transmitters might eventually share the same frequency band), the use of multiple antennas for interference reliving, jointly with a smart power allocation is compulsory. In addition, novel spectrum management regulatory policies are required for ensuring a peaceful coexistence between adjacent spectrum sharing networks and for promoting their development.
The aim of this dissertation is provide a beamforming and power allocation design for these novel spectrum sharing systems which are meant to exponentially increase the spectral efficiency of the systems. A mathematical framework based on multicriteria optimization for analyzing the beamforming design is provided which serves as a fundamental tool for describing the state-of-the-art studies in multiantenna interference networks. Indeed, the achievable rates are described and several ways of computing the Pareto rate region of MISO interference channel (i.e. the communication model that represents the spectrum sharing network when the transmitters use multiple antennas) are studied. Nevertheless, as the system designer aims to work in a single efficient rate point, the sum-rate optimal beamforming design is studied. Curiously, it results that under some realistic assumptions on both the desired and interference power levels, the obtained beamformer is the reciprocal version of a known receiving one and it optimizes a notion of antenna directivity for multiuser communications.
Neverthelss, it is important to remark that the higher transmit power is used, the more interference dominated is the medium, not only within the wireless network, but also to eventually adjacent networks that might suffer from inter-network interference. In order to cope with this problem, a spectrum licensing system is revisited, namely time-area-spectrum license. Under this spectrum management mechanism, a license holder is able to radiate signals under a certain portion of time, within a concrete area and in a given band. Moreover, the amount of signal strength within the area is constraint by a certain value. Since controlling the signal power levels in a given area is cumbersome, we propose to restrict the receive power as an estimation of the overall accumulated signal strength. Therefore, the optimal transmit beamformers and power allocations are studied. Concretely, the achievable rates are derived and an operational working point is envisaged. In addition, a suboptimal yet low computationally complex and decentralized beamforming design is presented and it shows a good performance in front of other decentralized designs.
Contribution to spatial bias mitigation in interferometric radiometers devoted to Earth observation : application to the SMOS mission
Authors:   , Wu Lin
Published: October 2023

This work has been undertaken within the frame of the FPI scholarship BES-2009-028505 of 30/07/2009, by the "Secretario de Estado de Investigación del Ministerio de Ciencia e Innovación", related to the project TEC2008-06764-C02-01 (Universitat Politècnica de Catalunya) titled "Advanced concepts on active and passive microwave remote sensing: technology and applications". In a more general scope, this thesis is related to the Remote Sensing Laboratory (Signal Theory & Communication Department, UPC) on-going activities, within the SMOS (Soil Moisture and Ocean Salinity) mission by the European Space Agency (ESA). These activities have been organized to provide original advances in the following four main topics:
1) SMOS system performance assessment. SMOS commissioning phase finalized in May 2010 providing preliminary performance results. Therefore, as a first step in this work, radiometric sensitivity and spatial bias (systematic spatial errors) have been reviewed and assessed. To achieve this, new techniques have been developed to better compare SMOS images to ground truth targets. SMOS ocean views have been selected as the best option since provide smooth brightness temperature distributions for which accurate models are available.
2) Spatial bias mitigation techniques. Spatial bias was a major issue in SMOS first images since it was larger than expected. In order to identify the dominant sources of spatial bias, each potential source of error, at calibration level,has been simulatedand compared tomeasured SMOS error patterns.
3) Spatial bias in the EAF-FoV. Whereas SMOS performance in the alias free FoV was well within mission requirements, this issue was especially important for the four polarimetric temperatures in the extended regions. This issuehas been addressed in two ways. First a new approach has been developed to systematically analyze spatial bias by splitting SMOS EAF-FoV into different regions of interest. Also, the pixels have been arranged per angle of incidence. Secondly, the impact in each region of calibration errors and different image reconstruction has been addressed.
4) Spatial bias in full-pol measurement.The main objective of this work has been achieved by developing, implementing and validating a SMOS full-pol G-matrix image reconstruction procedure that resulted into significantly improved polarimetric images. This tool allowed a comprehensive assessment of the two error contributions that have been identified as the main sources of residual spatial bias: the so-called floor error and antenna pattern uncertainty. Finally, as a validation of the quality of SMOS Level 1 fully polarimetric data that has been achieved, the last chapter of this work has been devoted to provide operational Faraday rotation retrievals in a per snap-shot basis.

This paper aims to study and quantify the impact of agricultural exports on economic growth along with other variables in Tunisia. For that purpose, we estimate the relationship between GDP, agricultural exports, other exports, and imports by applying the ARDL approach under the period 1990-2020. The results show a negative and insignificant impact of agricultural exports on economic growth in the long and short run. Other exports negatively and significantly impact economic growth, while imports are found to have a positive impact on long-term economic growth. The findings have economic implications for sectors and activities that should be promoted to accelerate economic growth.

O propósito deste artigo é discutir a Insubordinação Criativa (IC) como ação de resistência pelo campo da Educação Matemática (EM), em especial na formação inicial do educador matemático. Para tal, procuramos responder a seguintes questão: Quais as razões e o papel do uso da IC como ação de resistência? Identifica-se historicamente na trajetória de consolidação do campo da EM alguns conflitos e tensões entre professores de Matemática e educadores matemáticos, advindos do reconhecimento e demarcação de um campo de formação e pesquisa. De modo que, esses conflitos e tensões desafiam o educador matemático a ter uma postura de resistência para defender seu campo profissional. E ainda que seja um campo relativamente novo têm se desenvolvido bastante, tanto no âmbito acadêmico da formação de educadores matemáticos como no âmbito científico das pesquisas. Dessa forma, entendemos que os conflitos e tensões, mesmo não sendo, mas, tão evidentes quanto no início da institucionalização da EM, ainda aparecem de forma explicita ou implicitamente nas relações profissionais e nas práticas pedagógicas. Tais comportamentos podem trazer prejuízo para a formação inicial do educador matemático, contribuindo com concepções de resistência às práticas da EM.  Nessa perspectiva, fizemos estudos bibliográficos quanto aos conceitos de IC e campo científico, bem como suas relações com ações de resistência na Educação. Como resultado apontamos que a IC poderá promover ações de resistência Subversivamente Responsável por uma  Educação justa e de qualidade. E indicamos essa discussão para fortalecer, reconhecer e legitimar o campo de formação de futuros educadores matemáticos.
L’aristocratie romaine au sortir de la guerre civile
Authors: Hurlet Frédéric
Published: October 2023

Three of the main foundations of the new regime and the new life of the community as perceived by the Roman élites were: the return of peace – and therefore the disappearance of fear –, the restoration of the res publica, and the resulting feeling of tranquility and happiness. These were the key elements that Augustus was able to articulate to create a regime, whose birth coincided with the advent of the new golden age. This was the new state of mind that Augustus wanted to instill to put the civil wars behind him, and in which many Romans did not fail to recognize themselves because it was in their own interests to do so.

The focus of the work is the comparison of two passages (from Nazarius and Ammianus Marcellinus) in which the same exemplum concerning the presentation of the infant in the cradle at a particular time (before a war; against a usurped power) appears. Despite the obvious chronological, historical, and conceptual differences, one wonders why in relation to Constantine and his dynasty two sources in different times use the same exemplum. We also intend to proceed trying to understand whether there was a very particular ceremonial, that of the physical, visual presentation of the infant as dynastic and ritual legitimation.

Published: October 2023

The paper aims to evaluate the level of socioeconomic development of powiats (i.e. second level administrative units) in Wielkopolska province. With this purpose in mind a synthetic feature was utilized that aggregates simple features: partial indicators of socioeconomic development. The procedure of designing this feature used the generalized distance measure GDM to compute the distance from the ideal and anti-ideal points (Walesiak 1993, 2011), and TOPSIS method to aggregate the features (Hwang, Yoon 1981, Wysocki 2010). The measure of Walesiak (1993) facilitates calculating distances between features described on different scale types: ordinal, interval, or ratio, while TOPSIS is the standard method for aggregation of features. Proposed approach allows evaluating the level of socioeconomic development of powiats when expressed through simple features, both metric and ordinal. The evaluation process made use of the data gathered from the survey conducted in the powiat offices of the Wielkopolska province: “The present state and development potential of the powiats of Wielkopolska” (2000) and from the Local Data Bank of the Central Statistical Office report of 2010.

This study investigated sources of workplace stress, length of years in marriage and adjustment strategies among female lecturers in some selected state Colleges of Education, in North- West zone of Nigeria. The descriptive survey design was adopted for the study. The population of the study was 1003 female lecturers. A sample of four hundred and forty 440 married female lecturers was arrived at using purposive sampling techniques. Purposive sampling technique was used to distribute the sample across the selected schools. Three instruments were used for data collection; sources of workplace stress questionnaire adopted from Abubakar (2018), length of years in marriage questionnaire (self-developed), and adjustment strategies to sources of workplace questionnaire this instrument was adapted from Yusuf (2015). The reliability coefficient of 0.76, 0.78, and 0.75 respectively were found after using test re-test and Pearson Product Moment Correlation Coefficient statistics for the three instruments. Pearson Product Moment Correlation Coefficient statistic and multiple regression statistics were used to test hypotheses. Among the findings it was revealed that, there was a positive, high and significant relationship between length of years in marriage and adjustment strategies among female lecturers in some selected tertiary institutions in Sokoto State of Nigeria. The study concluded that length of years in services is more related to adjustment strategies. The study therefore recommended that, there should be adequate sensitization on sources of workplace stress and adjustment strategies. Female lecturers in tertiary institutions should be motivated to explore counselling in order to handle their challenges. Counselling centers should also be established in workplaces to assist employees in handling their adjustment strategies and sources of workplace stress.

The paper examined the prevalence of examination anxiety among undergraduates and its implications for counselling. The study employed a cross-sectional survey design in which 368 students were sampled from a population of 8,989 (male 60.6%; female 39.4%) undergraduates at Federal University Gusau (FUGUS) following a stratified random sampling technique. Data were obtained via an instrument called the University Examination Anxiety Scale (UEAS) whose reliability coefficient of 0.699 was estimated through the Cronbach Alpha statistic. Five null hypotheses were tested with t-test and Analysis of Variance (ANOVA) at 0.05 significance. Findings from the study revealed a significant prevalence of examination anxiety among undergraduates. Whereas the prevalence of examination anxiety did not differ with respect to gender, age group, and students-faculty, a significant difference was however established among the various levels of the undergraduate programme in the university. The implication of these findings for counselling is that the tension induced by test anxiety needs to be reduced to enable the students concentrate on their examination. This could be achieved by employing biofeedback and psycho-education approaches. The study recommends among others that counsellors should empower undergraduate students with simple strategies to reduce examination anxiety such as mindfulness techniques and simple deep breathing exercises.
Publishers: Serving Authors or Readers?
Authors: Eve Martin Paul
Published: October 2023

The most common way in which we can re-conceive of the economics of gold open access is to think of the publisher as providing a service to the author. After all, in an academic environment (where open access is most likely to flourish) authors are not usually writing their books to receive huge financial returns; they are, instead, paid through their salaried position.
The Anxiety of Academia: Academics, Legitimation and Discipline in Contemporary Metafiction
Authors: Eve Martin Paul
Published: October 2023

Since 2012, I have been slowly working on a book about contemporary metafiction. A lot of this work was done over weekends in the last year, as a break from the more practical undertakings that I do full-time in the week. The book was originally called “Metafiction After the Millennium” and was supposed to chart a type of post-postmodern (urgh) shift.

Tutorial 29, Appendix B: good, bad, and ugly titles of Matt’s papers
Authors: Wedel Matt
Published: October 2023

Last October, Mike posted a tutorial on how to choose a paper title, then followed it up by evaluating the titles of his own papers. He invited me to do the same for my papers. I waited a few days to allow myself to forget Mike’s comments on our joint papers – not too hard during my fall anatomy teaching – and then wrote down my thoughts. And then did nothing with them for three and a half months.

Dinosaur National Monument quarry map
Authors: Taylor Mike
Published: October 2023

The Carnegie Quarry, at Dinosaur National Monument, near Jensen, Utah, is arguably the most impressive dinosaur-fossil exhibit anywhere in the world — a covered, semi-excavated quarry that’s absolutely packed with big dinosaur fossils. It’s also notoriously difficult to photograph: too big to fit into a single photo, and with poor contrast between the bones and matrix.

Epipophyses, the forgotten apophyses: not just for sauropods!
Authors: Taylor Mike
Published: October 2023

Matt’s last post contained a nice overview of the occurrence of epipophyses in sauropodomorphs: that is, bony insertion points for epaxial ligaments and muscles above the postzygapophyseal facets. What we’ve not mentioned so far is that these structures are not limited to sauropods. Back when we were preparing one of the earlier drafts of the paper that eventually became  Why sauropods had long necks;

Bribery and Public Procurement Performance at Mbarara City, Uganda
Authors: Denis Nkamuhayo , Dennis Kakuba , Aggrey Muhereza , Bridget Nyakuhirwa
Published: October 2023

The study investigated the effects of bribery on public procurement performance in Uganda with a focus on Mbarara City. Specifically, the study examined how monetary bribery and non-monetary bribery influence public procurement performance at Mbarara City. A cross-sectional design adopting a quantitative approach was applied. Quantitative data was analyzed using inferential statistics (Spearman correlation, coefficient of determination and regression). Qualitative data on the other hand was analyzed using content and thematic analysis. The findings revealed a strong negative influence of bribery on public procurement performance whereby more bribery contributed to poor public procurement performance and less bribery contributed to better public procurement performance. The study recommended that municipal councils should develop mechanisms for strengthening and operationalizing available measures to combat bribery to improve public procurement performance. Such mechanisms may include encouraging whistle blowers, selection of professional and competent members on evaluation committees and reducing the bureaucracy.
