Evaluation of traffic controller performance via systematic exploration
No full textTraffic controllers must operate reliably across diverse traffic states. Due to the stochastic non-linear characteristics of traffic flow, commonly used feedback-based controllers require parameter tuning for each specific traffic regime, which is done offline using simulations. Generating representative traffic scenarios for large-scale simulations is often computationally expensive. To reduce the computational burden, this paper proposes a systematic exploration of the Structured Simulation Framework (SSF). This approach aims to approximate controller performance with a minimal number of simulations, by adjusting the parameter space continuously to regions where controller performances are weakly approximated. This process continues until controller performance is well approximated across the entire input domain. Results show SSF convergence of performance estimate of the controller while reducing the number of required simulations. This helps identify traffic scenarios where the controller performs poorly, and, thus, can be used as a framework towards guided controller tuning
Tabita Rezaire ::a megalithic space program
No full textTabita Rezaire is an interdisciplinary artist and activist exploring the intersections between technology, spirituality, decolonization and healing. She uses video, performance art and the creation of immersive spaces to challenge hegemonic narratives and advocate a holistic understanding of the world in which realities are interconnected. Her work focuses on the decolonization of knowledge and on researching the ways in which patriarchal and power structures shape our perception and use of technology. Rezaire’s work salvages ancestral knowledges and practices that were marginalized or silenced, and merges indigenous, African and non-Western knowledges with digital technologies to explore how spiritual and healing practices can be used as tools for resistance, emancipation and reconstruction of identities and communities
The manufacture of type for typewriters in Switzerland
No full textBetween the 1940s and the 1990s, three companies manufactured type components for typewriters in Switzerland: Caractères SA, Setag, and Novatype. For more than fifty years, they supplied the biggest manufacturers of office machines in Europe and around the world, such as IBM, Remington, Olivetti, Paillard-Hermès, and Triumph-Adler. Having held a leading position worldwide, the three manufacturers played a key role in the design, development, and production of type components and typefaces for typewriters, as well as for all kinds of impact printers. By looking in detail at their production methods, this article observes what influence the manufacturing processes and the mechanical characteristics of the typewriter had on the design of the typefaces. Additionally, it takes an interest in the surprising role played by the criminal police. Specialized in the dating and identification of typewriter typefaces for judicial and
criminal purposes, forensic experts developed over the years specific methods and compiled rich documentation on typewriter typefaces. Being in direct contact with the type manufacturers to gain first-hand information, they even interfered in the design of some letter shapes. Based on oral history and archival research, this project sheds light on this little-known part of the industrial and typographic history
The single-layer equivalent soil mass method for the evaluation of soil organic carbon stocks::sources of errors, simplification, and associated detectable change
No full textIt has been well established that for consistent soil organic carbon stock (SOCS) monitoring over time, the SOCS must be determined in an equivalent soil mass (ESM) layer rather than a depth layer. This work focused on the single-layer ESM method, its cost, accuracy and simplification. With the objective of simplifying ESM method and reducing costs, we sampled 393 fields in western Switzerland and experimentally questioned the sampling methods, the sources of variance and the minimum detectable change (MDC) of SOCS, and possible simplification. The layer mass was accurately determined using gouge-augers, thus overcoming a major drawback in performing ESM SOCS evaluation. The relationships between number of aliquots and estimated SOCS variance was determined. Sampling at fixed depth and layer bulk density resulted in unacceptable errors and MDCs exceeding several decades when converted to years before a change was detectable. We introduced a new procedure to fully consider the coarse fraction volume in the layer, which remains a major source of error on the SOCS when the coarse fraction volume exceeds 10 % of the layer volume, while not impacting the detectability of the change. The single-layer ESM method provided an MDC corresponding to less than 10 years before SOCS change detectability under the average regional conditions, and mass correction results in negligible increase in MDC compared to that of the 0–30 cm layer. Simplifying this method by using the average soil organic carbon content of the layer mass correction only slightly increased the MDC, thus providing an opportunity to decrease the cost of SOCS monitoring significantly
Design and development of pilot photobioreactor for simultaneous microalgae cultivation and aquaculture wastewater treatment
No full textThis study presents an innovative and modular phototrophic biofilm photobioreactor (PBR) designed for the simultaneous cultivation of algae and the treatment of aquaculture wastewater (AWW). The vertical flat-plate BPR allows for stable microalgae growth while efficiently removing nutrients from wastewater under controlled conditions, including light, CO2, supplementation, water recirculation and continuous monitoring of parameters such as pH, nitrate (NO3-N) and phosphate (PO43-P). The PBR was operated at an aquaculture facility using AWW, with nutrient removal and microalgal growth being monitored. The microalgae consortium composed of Chlorella sp., Scenedesmus sp. and Phormidium sp. were evaluated for their growth potential and wastewater remediation capabilities. Results showed high nutrient removal efficiencies with 92 % reduction of PO43-P (removal rate: 0.07 mg/L d) and a 62 % reduction of NO3--N (removal rate: 1.1 mg/L d), bringing nutrient concentrations below the limits set by the Waters Protection Ordinance. Maximum biomass production reached a growth rate on land surface of 25 g/m2/d, with a favorable biochemical composition of 51 % proteins, 25 % carbohydrates and up to 8 % lipids, indicating the potential for use animal feed. This study demonstrates the feasibility of using AWW as a growth medium for microalgae while simultaneously achieving wastewater remediation, offering a sustainable solution for nutrient recycling in aquaculture operations
Hypergraph reconstruction from dynamics
No full textA plethora of methods have been developed in the past two decades to infer the underlying network structure of an interconnected system from its collective dynamics. However, methods capable of inferring nonpairwise interactions are only starting to appear. Here, we develop an inference algorithm based on sparse identification of nonlinear dynamics (SINDy) to reconstruct hypergraphs and simplicial complexes from time-series data. Our model-free method does not require information about node dynamics or coupling functions, making it applicable to complex systems that do not have a reliable mathematical description. We first benchmark the new method on synthetic data generated from Kuramoto and Lorenz dynamics. We then use it to infer the effective connectivity in the brain from resting-state EEG data, which reveals significant contributions from non-pairwise interactions in shaping the macroscopic brain dynamics

Rethinking the assessment of arthrogenic muscle inhibition after ACL reconstruction: implications for return-to-sport decision-making—a narrative review
No full textArthrogenic muscle inhibition (AMI) is a neuromuscular impairment commonly observed following anterior cruciate ligament reconstruction (ACLR). This condition, characterized by persistent quadricep inhibition due to altered afferent feedback, significantly impacts neuromuscular recovery, delaying return to running and sport. Despite advancements in rehabilitation strategies, AMI may persist for months or even years after ACLR,
leading to muscle strength asymmetries, altered biomechanics, and an increased risk of reinjury. The mechanisms underlying AMI involve both peripheral (joint effusion, mechanoreceptor dysfunction) and central (corticospinal inhibition, neuroplasticity alterations) components, which collectively hinder voluntary muscle activation and movement
control. AMI alters gait mechanics, reduces knee stability, and promotes compensatory patterns that increase injury risk. Current return-to-sport protocols emphasize strength symmetry and functional performance but often neglect neuromuscular deficits. A comprehensive assessment integrating neuromuscular, biomechanical, and proprioceptive
evaluations is needed at specific stages to optimize rehabilitation and minimize reinjury risk. Future research should explore targeted interventions such as neuromuscular stimulation, cognitive–motor training, and advanced gait analysis to mitigate AMI’s impact and
facilitate a safer, more effective return to sport
