Cost Optimization of Prestressed U-Shaped Simply Supported Girder Using Box Complex Method
Authors: Khan Muhammad Salman , Peng Tianbo , Ali Syed Muhammad , Rehman Faisal Ur , Wu Yicheng
Published: July 2023

The use of U-shaped girders has become increasingly popular in advanced projects such as metro rail systems due to their ability to provide greater vertical clearance beneath bridges. These girders, characterized by two webs and a bottom flange, contribute essential longitudinal stiffness and strength to the overall structure while effectively countering torsional forces in curved bridges. However, the design and construction of U-shaped girders present challenges, including their relatively higher self-weight compared to other girder types. Consequently, cost optimization has become a crucial focus in structural design studies. This research aims to develop an optimization model for prestressed U-shaped girders using the AASHTO LRFD bridge design specifications. The model is based on the Box complex method, with necessary modifications and improvements to achieve an optimal design. The objective is to minimize the total cost of materials, including concrete, steel reinforcement, and prestressing strands, while satisfying explicit and implicit design constraints. To facilitate the analysis, design, and optimization processes, a program is developed using Visual Studio 2010 and implemented in Visual Basic (VB.NET). The program incorporates separate subroutines for analysis, design, and optimization of the prestressed U-shaped girder, which are integrated to produce the desired results. When running the program, the optimization process required 229 iterations to converge to the optimal cost function value. The results demonstrate that the developed algorithm efficiently explores economically and structurally effective solutions, resulting in cost savings compared to the initial design. The convergence rate of the moment capacity constraint is identified as a key factor in achieving the optimal design. This research makes a significant contribution to the field of civil engineering by applying the classical Box complex method to the optimization of girders, an area where its utilization has been limited. Furthermore, this study specifically addresses the optimization of prestressed U-shaped girders in metro rail projects, where they serve as both the deck and support structure for train loading. By employing the Box complex method, this research aims to fill the research gap and provide valuable insights into the optimization of U-shaped girders. This approach offers a fresh perspective on designing these girders, considering their unique role in supporting metro rail loads. By leveraging the benefits of the Box complex method, researchers can explore new possibilities and uncover optimal design solutions for U-shaped girders in metro rail applications.

Published: July 2023

The pursuit of sustainability in the construction and demolition (C&D) sector calls for effective decision-making strategies, both in terms of technical and environmental sustainability, capable of mitigating its huge demand for resources and emissions to the environment. The recycling of C&D waste is one of the potential solutions that could reduce the extraction of virgin materials as well as waste generation and landfilling. This study evaluates and compares, by means of the Life Cycle Assessment (LCA) approach, the production of concrete via five different mixtures made up of coarse natural aggregates (NA, primary, virgin materials), and coarse recycled concrete aggregates (RCA, recovered from previous uses). The present study assesses the environmental load of concrete production, by means of mixtures containing only coarse NA and mixtures with coarse RCA produced in fixed and mobile treatment plants, to be replaced with 30% and 100% of coarse NA by weight. The results point out that the use of coarse RCA in concrete mixtures provide greater energy savings and environmental advantages compared to the concrete with only coarse NA; the improvement increases up to a 100% replacement rate by weight of coarse NA with coarse RCA in the mixtures. In this case, the reduction of the impacts is significant for some impact categories such as freshwater ecotoxicity (−63.4%), marine ecotoxicity (−76.8%), human carcinogenic toxicity (−27.1%), human non-carcinogenic toxicity (−77.9%), land use (11.6%), and water consumption (−17.3%), while the total CED impacts decreases by about 10% and that of GWP by 0.4%. Results are discussed in light of the urgent need for advancing circular economy concepts and practices in the C&D sector and decrease the large use of primary resources (in particular sand and gravel). The replacement of NA with RA by weight could contribute to reducing the impacts of the C&DW management and disposal. For this to happen, further improvement of the quality of recycled aggregates is essential for their market development as well as dedicated policies and legislations.
Perceptions of Ecosystem Services and Climate Change in the Communities Surrounding Mt. Kenya and Mt. Elgon, Kenya
Authors: Downing Timothy , Olago Daniel , Nyumba Tobias
Published: July 2023

Local observations of climate change can be a critical resource for understanding the impacts of climate change, particularly in data-scarce areas. This study examines local observations of climate change in two montane areas of Kenya- Mt. Kenya and Mt. Elgon. Household questionnaires, focus group discussions, and interviews were used to explore local perceptions of ecosystem services and changes to those services. Results showed that communities had a strong appreciation for ecosystem services and had witnessed major changes in those services. Water provision was seen as the most important service and the one that had changed the most. Other observations of changes included shifts in species ranges, weather patterns, temperature, and soil properties. These changes are consistent with predictions from climate models, but they provide context-specific nuance that the models cannot provide. Spatial variables, such as distance to road and the alpine zone, played as large or larger role in affecting perceptions as demographics, which further points to the importance of context in understanding climate changes. Those that interacted with the mountains the most—the mountain guides—had particularly revealing observations of changes; these types of observations can be critical to understand and prepare for changes in the alpine areas of Kenya.

In Bangladesh’s hill regions, where there is less cultivable land, increasing crop output requires efficient land use. Thus, in this challenging farming setting, two crop-based patterns evolved into three or four crop-based patterns. To increase cropping intensity and farmer income by incorporating mustard and mungbean in a rice-based cropping pattern, a field experiment was carried out at Sadar and Panchari Upazila, Khagrachhari during 2017–2018 and 2018–2019. Two years’ mean data (using a block farming approach) showed that the modified pattern had produced a much higher yield through improved management practices. In the improved cropping pattern (Transplant aman (T. aman)–mustard–mungbean–aus rice), a higher rice equivalent yield (16.25 t ha−1) was found due to the inclusion of mustard and mungbean in the existing rice-based cropping patterns T. aman–fallow–boro (9.87 t ha−1) and T. aman–fallow–tomato (9.09 t ha−1). The gross margin from the improved cropping pattern was 448,715 BDT, which was 44.26% higher than the mean gross margin (311,050 BDT) of the two existing cropping patterns. Farmers are interested in growing mustard and mungbean since both can easily cultivated in hilly areas and can yield great economic returns quickly. For the large-scale production of oil and pulse, the T. aman–mustard–mungbean–aus rice cropping pattern might be introduced in the Khagrachhari district of Bangladesh.
Impact of the Urban-Rural Income Disparity on Carbon Emission Efficiency Based on a Dual Perspective of Consumption Level and Structure
Authors: Zou Xiuqing , Ge Tianyue , Xing Sheng
Published: July 2023

Utilizing Chinese provincial panel data from 2006–2019, this paper applies the super-efficient epsilon-based measure (EBM) model including non-desired output to measure carbon emission efficiency (CE) and analyze spatio-temporal characteristics of CE, in which social fixed asset investment, energy consumption and urban employment per unit are used as input indicators and regional GDP and CO2 emissions are used as output indicators. Additionally, we use the spatial Durbin model to explore the impact of urban-rural income disparity (URID) on carbon emission efficiency and its spatial spillover effect and explore indirect mechanisms of consumption level and consumption structure on CE using mediating effect test. The results showed that: (1) The national CE level generally declined between 2006–2012 and fluctuated upward from 2013–2019. The trend of regional CE showed “high in the east and low in the west”. (2) The “inverted U” model accurately reflects the relationship between national CE and URID, with a “U” shaped association in the central, western, and northeastern regions, and a positive correlation with consumption level and consumption structure. (3) There is a significant mediating effect of consumption level and structure in the mechanism of URID in regulating CE. Local governments should adopt local policies, take measures to narrow URID and CLD, advocate low-carbon and environmentally friendly living for residents, and promote the upgrading of consumption structure to boost carbon emission efficiency.

Published: July 2023

Teachers play an essential role in teaching sustainable development to students. Consequently, understanding the challenges that hamper effective instruction is crucial. This study explored the challenges preparatory and secondary school teachers face in Qatar’s public and private schools when teaching Education for Sustainable Development (ESD) and Global Citizenship Education (GCED). The study utilized an adapted version of UNESCO’s global survey to investigate these challenges and shed light on the obstacles that impede effective instruction in these essential domains. Teachers’ (N = 981) challenges were assessed according to curricular, cultural, and environmental challenges associated with teaching sustainability. The study results indicated that more than half of public and private school teachers faced moderate to significant challenges when teaching ESD and/or GCED themes. Sustainable Consumption and Production was perceived as the most challenging teaching theme, with the least curriculum coverage. Results indicated that private school teachers report more significant challenges in teaching and assessing ESD/GCED themes than public school teachers across the four sustainability themes. Detailed discussion regarding these findings is provided. This article contributes to the wider academic conversation by examining the practical challenges teachers face in Qatar as they implement ESD and GCED.

Published: July 2023

The strong influence of the media could be leveraged for increasing investments in renewable energy sources (RES), which, in turn, assist the transition to a low-carbon energy system that aligns with renewable energy targets. However, it is not known whether media information facilitates citizens interested in investing. Hence, the aim of this study is to support the decision-making of citizens by improving media information about renewable energy investments. Specific objectives are to measure citizen satisfaction with media information about RES investments and to detect the areas that require immediate attention. To that end, 1536 Greek citizens recruited with simple random sampling were administered structured questionnaires and, to analyze citizen satisfaction, multiple criteria satisfaction analysis was applied. According to results, citizens were not satisfied with media information about RES investments, while the lowest satisfaction was recorded for information about available subsidies for RES investments, as well as changes in the institutional framework. This finding has potentially important implications as inadequate information about investments may prevent interested citizens from investing. Given that investment schemes undergo constant changes and that journalists may not be experts in investments, it is recommended to tailor information to citizens’ understanding and that academics and experts provide the media with simplified information material about RES investments.
Numerical Simulation of Conjugate Mixed Convection in 3D Channel with Heat-Generating Flat Element and Symmetrical Solid Two-Fin System
Authors: Gibanov Nikita , Sheremet Mikhail
Published: July 2023

This paper presents the numerical simulation results of conjugate mixed convection in a three-dimensional channel with a heat-generating element and solid fins. It should be noted that the symmetrical location of fins has been studied. The system of partial differential equations, presented in dimensionless form using velocity and vorticity vectors, has been solved by the finite difference method on a uniform grid. The central difference schemes have been used to approximate diffusive terms. In contrast, for an approximation of convective terms, the monotonic Samarskii difference schemes have been applied to improve the stable properties of central differences of the second order of accuracy. Analysis has been performed on a wide range of governing parameters, including the Reynolds number (200 ≤ Re ≤ 1000), the material of the fins (aluminum, copper, and iron), and the location of the fins on the heater surface, taking into account the identical distances between the fins and the nearest walls. Water has been considered a working cooling medium. The obtained outcomes characterize the most efficient heat removal from the surface of the energy source using the considered fin system. For example, by using copper fins, the cooling efficiency of the heating element can be increased. The average heater temperature decreases significantly with an increase in the Reynolds number. The distance between the fins also makes a significant contribution to the cooling phenomenon. It is noted that with the most successful choice of location, it is possible to decrease the temperature of the heater by more than 12%.
Symmetry and Asymmetry in Moment, Functional Equations, and Optimization Problems
Authors: Olteanu Octav
Published: July 2023

The purpose of this work is to provide applications of real, complex, and functional analysis to moment, interpolation, functional equations, and optimization problems. Firstly, the existence of the unique solution for a two-dimensional full Markov moment problem is characterized on the upper half-plane. The issue of the unknown form of nonnegative polynomials on R×R+ in terms of sums of squares is solved using polynomial approximation by special nonnegative polynomials, which are expressible in terms of sums of squares. The main new element is the proof of Theorem 1, based only on measure theory and on a previous approximation-type result. Secondly, the previous construction of a polynomial solution is completed for an interpolation problem with a finite number of moment conditions, pointing out a method of determining the coefficients of the solution in terms of the given moments. Here, one uses methods of symmetric matrix theory. Thirdly, a functional equation having nontrivial solution (defined implicitly) and a consequence are discussed. Inequalities, the implicit function theorem, and elements of holomorphic functions theory are applied. Fourthly, the constrained optimization of the modulus of some elementary functions of one complex variable is studied. The primary aim of this work is to point out the importance of symmetry in the areas mentioned above.
Effects of Path-Finding Algorithms on the Labeling of the Centerlines of Circle of Willis Arteries
Authors: Kim Se-On , Kim Yoon-Chul
Published: July 2023

Quantitative analysis of intracranial vessel segments typically requires the identification of the vessels’ centerlines, and a path-finding algorithm can be used to automatically detect vessel segments’ centerlines. This study compared the performance of path-finding algorithms for vessel labeling. Three-dimensional (3D) time-of-flight magnetic resonance angiography (MRA) images from the publicly available dataset were considered for this study. After manual annotations of the endpoints of each vessel segment, three path-finding methods were compared: (Method 1) depth-first search algorithm, (Method 2) Dijkstra’s algorithm, and (Method 3) A* algorithm. The rate of correctly found paths was quantified and compared among the three methods in each segment of the circle of Willis arteries. In the analysis of 840 vessel segments, Method 2 showed the highest accuracy (97.1%) of correctly found paths, while Method 1 and 3 showed an accuracy of 83.5% and 96.1%, respectively. The AComm artery was highly inaccurately identified in Method 1, with an accuracy of 43.2%. Incorrect paths by Method 2 were noted in the R-ICA, L-ICA, and R-PCA-P1 segments. The Dijkstra and A* algorithms showed similar accuracy in path-finding, and they were comparable in the speed of path-finding in the circle of Willis arterial segments.
Long-Term Exposure to Cadmium Causes Hepatic Iron Deficiency through the Suppression of Iron-Transport-Related Gene Expression in the Proximal Duodenum

Published: July 2023

Cadmium (Cd) is an environmental pollutant that damages various tissues. Cd may cause a depletion of iron stores and subsequently an iron deficiency state in the liver. However, the molecular mechanism of decreased iron accumulation in the liver induced by long-term exposure to Cd is unknown. In this study, we investigated the hepatic accumulation of iron and the proximal duodenal expression of the genes involved in iron transport using mice chronically exposed to Cd. Five-week-old female C57BL/6J mice were fed a diet containing 300 ppm Cd for 12, 15, 19 and 21 months. The iron concentration in the liver was markedly decreased by Cd. Among iron-transport-related genes in the proximal duodenum, the gene expression of HCP1 and Cybrd1 was significantly decreased by Cd. HCP1 is an influx transporter of heme iron. Cybrd1 is a reductase that allows non-heme iron to enter cells. The expression of iron-transport-related genes on the duodenal basolateral membrane side was hardly altered by Cd. These results suggest that long-term exposure to Cd suppresses the expression of HCP1 and Cybrd1 in the proximal duodenum, resulting in reduced iron absorption and iron accumulation in the liver.

Published: July 2023

Intoxication of vitamin D is not a common case in pediatrics. Vitamin D supplements are sold as OTC drugs; however, there is a lack of public education about the permissible limits of vitamin D intake which may lead to vitamin D toxicity (VDT). This review aims to give insights to readers or practitioners about the clinical toxicology of vitamin D in pediatrics, which includes the mechanism of VDT, case reports, and the management of vitamin D poisoning. VDT refers to serum 25(OH)D levels, particularly when the level exceeds 100 ng/mL (250 nmol/L) or is defined as hypervitaminosis D. Hypercalcemia is a common condition of vitamin D toxicity. Vitamin D and its metabolites in moderate levels can induce hypercalcemia, as indicated by the elevation of osteoclastic bone resorption, the presence of calcium in renal tubules, intestinal calcium intake (through increased production of calcium-binding protein in enterocytes), and the decrease of parathyroid hormone synthesis. VDT in pediatrics can be managed by discontinuing vitamin D intake; using activated charcoal, furosemide, prednisone, and calcitonin; rehydration using intravenous sodium chloride 0.9%; and dextrose fluid therapy. It is important for parents to be more careful when providing vitamin D to their children.

Published: July 2023

Ante-mortem and post-mortem inspection at slaughter are performed by Official Veterinarians and it is essential to identify alterations/lesions, which can make organs/carcasses unsuitable for human consumption. Obviously, carcass condemnation must be regarded as a highly undesirable event for the entire swine industry chain, as it represents the total failure of a long period of challenging work. Therefore, it seems valuable to estimate the prevalence and causes of carcasses condemnation, in order to preserve consumers’ health and pig farming profitability. Bearing that in mind, the present study aimed at providing a reliable picture of the condemnation of porcine carcasses in Italy, with a special emphasis being placed upon pathological findings. Data were collected in a high-throughput abattoir located in northern Italy, where a total of 2,062,278 pigs were slaughtered during the period of study (2021–2022). Overall, 1362 pigs were considered unfit for slaughtering after ante-mortem inspection, mostly because of death during transportation or in resting pens, after their arrival at the abattoir. Moreover, 2007 carcasses were condemned after post-mortem inspection. The most common causes of condemnation were severe and diffuse peritonitis, disseminated abscesses, jaundice, and erysipelas. In our opinion, the present survey may provide useful and updated information about the condemnation of pig carcasses in Italy. At the same time, it highlights the need to collect data in a more systematic and standardized way, thus making possible their comparison over time and among different geographic areas.

Published: July 2023

The study aimed to determine groundwater’s suitability for irrigation and cattle rearing in Kuwait. In this regard, groundwater samples were collected from Umm Al Aish (UA) and adjoining Rawdhatain (RA) water wellfields to develop groundwater suitability maps for irrigation purposes using the fuzzy logic technique in ArcGIS. RA was dominated by Na-Cl, Na-Ca, and Ca-SO4 water types, whereas UA was dominated by the Ca-Mg water type. Due to the influence of the temperature and pCO2, the carbonates were inferred to be more susceptible to precipitation in the soil than the sulfates. The ternary plots for both regions revealed that the samples’ suitability ranged from good to unsuitable. Spatial maps of nine significant parameters governing the irrigation suitability of water were mapped and integrated using the fuzzy membership values for both regions. The final suitability map derived by overlaying all the considered parameters indicated that 8% of the RA region was categorized as excellent, while UA showed only 5%. Samples situated in the study areas showed an excellent to very satisfactory range for livestock consumption. Developing a monitoring system along with innovative water resource management systems is essential in maintaining the fertility of the soil and existing groundwater reserves.

Published: July 2023

Eryngium heterophyllum Engelm, known as “toad grass”, has been traditionally used in renal diseases. The aim of the study was to evaluate the diuretic activity of the aqueous extract in the rat. The vegetal material was collected, identified, and the preliminary phytochemical study was carried out. For the diuretic evaluation, Wistar rats, female, adult of 200 ± 20 g of body weight (b.w.) were used, and they were distributed in five groups: the vehicle, the furosemide group (4 mg/kg of b.w.) and the aqueous extract at the doses of 200, 400 and 800 mg/kg of b.w., per os. After six hours in metabolic cages, urine and serum samples were obtained to measure the concentrations of sodium, potassium and creatinine. With these data, urine flow and creatinine, Na+ and K+ clearance, excretion and filtered ion load were calculated. LD50 in femal NIH mice, adults of 25 ± 5 g of b.w., treated with the extract (1, 2, 4 and 8 g/kg of b.w.) was determined. Decoction is used and the phytochemical study coumarins, alkaloids, flavonoids, tannins and saponins were detected. In the diuretic evaluation, an increase in the urinary flow, in the urinary excretion and ion clearance in the groups treated with furosemide and at different doses of the extract were observed. The LD50 is higher than 8 g/kg of b.w. Eryngium heterophyllum Engelm diuretic action was induced by direct renal tubular effect. The study of plant species is important to support their empirical use.

Introduction. A mental health survey was done in the context of the COVID-19 pandemic among Latin American dermatologists through CILAD (Colegio Ibero-Latinoamericano de Dermatología) with the participation of both specialists and residents from twenty countries. Objective. To evaluate mental health problems among Latin American dermatologists during the COVID-19 pandemic. Material and Methods. This quantitative, cross-sectional comparative study took place between June and July 2020. The evaluation, made online, had two sections: the first one explored the socio-demographic variables, and the second was a filter including self-application instruments for the assessment of Post-Traumatic Stress Disorder (PTSD), general anxiety, health anxiety and somatic symptoms, and risk of depression. Results. The sample included a total of 554 subjects, most of them women and dermatologists. In the mental health assessment, there were differences between those dermatologists who care for COVID-19 and those who do not regarding a greater use of drugs; 21.5% of dermatologists reported being COVID-19 first-line care health personnel. The risk of having PTSD is significantly higher among them than among those who do not work with COVID-19 patients (36.8% vs. 16.6%); they have more insomnia incidence (21.8% vs. 10.8%); more risk of depression (66.6% vs. 47.6%) and greater consumption of substances (15.1% vs. 5.3%). Conclusions. Dermatologists and dermatology residents at the first line of care in the current pandemic show identifiable mental health problems; thus, mitigation measurements have to be taken about it.

Geçici Hayvan Bakımevleri İçin Hata Türleri ve Etkileri Analizi (FMEA) Örneği
Authors: ÇAĞLARER Evren , ARICAK Filiz
Published: July 2023

Kısırlaştırma işlemi hayvanların üremesini kalıcı bir şekilde durdurmak için yapılan cerrahi bir müdahaledir. Ülkemizde sahipsiz sokak hayvan sayısı milyonlarla, buna karşılık kısırlaştırılan sokak hayvan sayısı binli sayılarla ifade edilmektedir (Tarım ve Orman Bakanlığı,2022). Sokakta yaşayan, başıboş kedi köpek gibi evcil hayvanların popülasyonundaki kontrolsüz büyümenin önüne geçmek için kısırlaştırma işlemleri yerel belediyelere ait geçici hayvan bakımevlerinde yapılır. Kısırlaştırma işlemi anestezi eşliğinde yapılan basit bir operasyon olarak görünse de alt süreçlerine bakıldığında olası hataların oluşturacağı tehlike ve risklerle göz ardı edilmemesi gereken bir süreçtir. Bu konuda potansiyel tehlikelerin belirlenmesi ve sonuçlarının analizini yapılması risk değerlendirmeleri ile mümkün olur. FMEA (Hata Tür ve Etkileri Analizi Risk Analizi), basitliği ve görünürlüğü göz önüne alındığında başta sağlık hizmetleri olmak üzere çoğu alanda kalite iyileştirme çalışmaları için sıklıkla kullanılan bir yöntemdir. Uygulaması kolay ve maliyeti düşüktür. Bu yöntemle yüksek riskli süreçlerde oluşabilecek hatalar önceden tespit edilerek, hastaya ulaşmadan önce önlem alınabilir ve böylece hataların oluşma sıklığı düşürülebilir.

İş sağlığı ve güvenliği kapsamında yapılan risk değerlendirme çalışmaları çalışanın ve çalışma ortamının risklerini değerlendirmek için yapılır. Çalışmamızda gerçekleştirilen risk analizi ile geçici hayvan barınakları ve burada kısırlaştırılan hayvanların sağlık ve güvenliği hedeflenmiştir.

FMEA yöntemi kullanılarak yapılan analizde; öncelikle bir risk analiz ekibi kurularak, iş akış şeması çıkarılmıştır. Ardından operasyon için adım diyagramları hazırlanmış ve tehlikeler tespit edilmiştir. Sonuçta oluşturulan risk analizi uzman ekip tarafından değerlendirilmiştir. Buna göre geçici hayvan barınaklarında gerçekleştirilen kısırlaştırma işleminin FMEA ile 6 tane alt süreç irdelemesi yapılmış, toplamda 17 olası hata türü belirlenmiştir. Hata türlerinin tayin edilen olasılık ve şiddetine bağlı olarak risk skorları bulunmuştur. Yapılan risk değerlendirmesinin kazaları meydana getirebilecek her türlü unsurun bertaraf edilmesinde önemli etkisinin olduğu açıktır.

Las personas privadas de la libertad forman parte del grupo de personas vulnerables, su adecuada atención permitirá entre otros aspectos la eficiencia del sistema carcelario; es por ello por lo que, ante la crisis que se presenta en el Ecuador, es necesario que el Estado evalúe y establezca las medidas necesarias para reducir el uso de la prisión preventiva considerando como prioridad la protección del derecho a la libertad y el principio de presunción de inocencia.

Increased ranging accuracy of RFID tags in ETSI regions using 53MHz wide dual bands
Authors: Le Breton Mathieu
Published: July 2023

Passive RFID tag localization has numerous applications, which can benefit from improved accuracy. Ranging methods based on phase difference of arrival become more accurate with higher frequency bandwidth. European regions, following ETSI regulation, historically allowed a single ultra-high fre-quency band (865–868 MHz) with limited accuracy. Recently allowed, the second band (915–921 MHz) increases the fre-quency range from 1.8 MHz to 53 MHz, but with a significant gap between the bands. In a dual-band experiment, distance estimates were obtained between two reader antennas and 17 tags across 6 arrays. The results revealed a new 3.07 m ambi-guity cycle due to the frequency gap, that adds to the existing  0.17 m phase ambiguity. Solving the new ambiguity on 88% of tag-antenna combinations and 100% of the arrays resulted in a maximum error of 0.55 m (median 0.26 m), significantly im-proving accuracy (×6.5) compared to the former single-band ranging. Looking ahead, the adoption of dual-band ranging could enhance the accuracy of various tag localization methods in ETSI-regulated regions.
