Integrating collision avoidance strategies into multi-robot task allocation for inspection

Recent research topics have been placed on reinforcing security and safety measures within high-risk industries to protect both equipment and the environment. Numerous industries carry substantial implications for their surroundings. During significant incidents like chemical spills, or nuclear accidents, swiftly gathering precise and dynamic data poses a considerable challenge. Subsequently, this paper focuses on optimizing a mission involving multiple mobile robots charged with inspecting an industrial zone. The aim of this research is to efficiently collect measurements from diverse positions using a fleet of sensing robots operating from a central depot, that is, developing an algorithm for robot decision-making that optimizes mission planning by minimizing an objective function. Initially, we explore our previous proposed solutions and we improve the system by integrating a navigational layer to manage collision avoidance between robots. Then, we delve into scenarios involving multiple homogeneous tasks distributed in a limited geographical environment. To demonstrate feasibility, extensive simulations, numerical experiments, and comparative analysis are conducted, showing the efficiency of the proposed approaches in terms of solution quality and computational complexity.

Management of Recurrent Clostridioides difficile Infection (rCDI): A Systematic Literature Review to Assess the Feasibility of Indirect Treatment Comparison (ITC).

Recurrent Clostridioides difficile infection (rCDI) is a major cause of increased morbidity, mortality, and healthcare costs. Fecal-microbiota-based therapies are recommended for rCDI on completion of standard-of-care (SoC) antibiotics to prevent further recurrence: these therapies include conventional fecal-microbiota transplantation and the US Food and Drug Administration-approved therapies REBYOTA® (RBL) and VOWST Oral Spores™ (VOS). As an alternative to microbiota-based therapies, bezlotoxumab, a monoclonal antibody, is used as adjuvant to SoC antibiotics to prevent rCDI. There are no head-to-head clinical trials comparing different microbiota-based therapies or bezlotoxumab for rCDI. To address this gap, we conducted a systematic literature review to identify clinical trials on rCDI treatments and assess the feasibility of using them to conduct an indirect treatment comparison (ITC). The feasibility analysis determined that trial heterogeneity, particularly relating to inclusion criteria, may significantly compromise ITC and prevent cross-trial comparisons. Our analysis underlines the need to adopt standardized protocols to ensure comparability across trials.

Universal mental health training for frontline professionals (UMHT)’s feasibility analysis

Background Universal Mental Health Training for Frontline Professionals (UMHT) is an educational programme developed and piloted in Ukraine in 2021-2023. The UMHT trains frontline professionals (FLPs) to interact with, support, and refer individuals with mental health conditions for professional help. Methods To assess the UMHT feasibility in four focus areas (programme’s demand, acceptability, adaptability, and extendability), we used statistics on the actual use of the programme, as well as data from satisfaction and usability surveying of 144 programme deliverers and 714 trained frontline professionals. A combination of Kruskal-Wallis and Post Hoc Dunn tests was used to identify statistically significant intergroup differences in the UMHT usability. Results Programme’s demand increased through years of implementation (2021, 2022, 2023) in terms of the numbers of training events (27, 35, 90), trained frontline professionals (596, 779, 1548), involved donors and supporters (1, 4, 9) and implementers (2, 10, 18). The UMHT acceptability as satisfaction with the programme content and delivery, measured out of 5, is 4.81 (SD=0.291) for the UMHT trainers and 4.78(SD=0.434) for trained FLPs. The UMHT preparedness to use trained skills after participation in the training events, on the same scale, is 4.57 (SD=0.438) for the UMHT trainers and 4.46 (SD=0.650) for trained FLPs. The highest levels of usability of all UMHT skills on a scale from 0 to 1 were found for educators (0.68 [SD=0.118]), police officers (0.67 [SD=0.098]), and social workers (0.66 [SD=0.113]). Conclusions The UMHT offers a universal frame of interaction with people with mental health conditions for frontline professionals. Assessment of the UMHT feasibility shows the programme’s potential for further development and implementation. Programme trainers as its deliverers and frontline professionals as its recipients report high satisfaction with training content and delivery as well as preparedness to apply gained knowledge and skills in practice.

Lighting Up Dual-Aptamer-Based DNA Logic-Gated Series Lamp Probes with Specific Membrane Proteins for Sensitive and Accurate Cancer Cell Identification.

Accurate identification of cancer cells under complex physiological environments holds great promise for noninvasive diagnosis and personalized medicine. Herein, we developed dual-aptamer-based DNA logic-gated series lamp probes (DApt-SLP) by coupling a DNA cell-classifier (DCC) with a self-powered signal-amplifier (SSA), enabling rapid and sensitive identification of cancer cells in a blood sample. DCC is endowed with two extended-aptamer based modules for recognizing the two cascade cell membrane receptors and serves as a DNA logic gate to pinpoint a particular and narrow subpopulation of cells from a larger population of similar cells. DCC leverages a dual-receptor co-recognition strategy for enhanced specificity of cell identification by performing the matching operation between aptamer and receptor twice on cell membranes. SSA is a signal converter attached at the end of DCC that changes the cell identification process into detectable signals, as well as a signal amplifier to output amplified signals by using a simple and efficient hybridization chain reaction. Unique from those who are multicomponent systems, DApt-SLP is an all-in-one compact DNA nanodevice, exhibiting an enhanced nuclease-degradation resistance and targeting ability. In vitro feasibility, cell imaging, and flow cytometry analysis showed that the DApt-SLP system successfully operated under buffered solution and physiological environment and precisely differentiated the target cell from large populations of similar cells. Benefiting from its integrated design and single-step cancer cell identification with high sensitivity and accuracy, the DApt-SLP system is a practical tool in personalized medicine and biomedical engineering.

Technical and economic feasibility analysis of a subsea shuttle tanker for CO2 transport to the troll field

The Subsea Shuttle Tanker (SST) was presented by the authors as an innovative and cost-effective solution in several research works. This new approach offers a viable alternative to subsea pipelines and shuttle tanker ships for transporting liquid CO2 from onshore facilities to marginal offshore reservoirs. A previous technical–economic feasibility study found that the SST is generally economically competitive to the subsea pipelines and shuttle tanker ships for distances below 180 km and CO2 transport volumes of one million tons per annum (mtpa). The economic cost models are based on those developed in Maritime UN-manned Navigation through Intelligence in Network (MUNIN) D 9.3 and the Zero Emission Platform (ZEP) projects. This paper will take this previous study further by focusing on performing the technical and economic feasibility analysis for operation in the Troll field on the Norwegian continental shelf (NCS), which has a transport distance of 65 km and a CO2 volume of 1.5 mtpa. Two SST design solutions are investigated by downscaling and upscaling the reference baseline design to evaluate SST’s technical feasibility. Using the abovementioned cost models, the CO2 transportation cost per ton using SST is compared with subsea pipelines and tanker ships. The numerical results show that it is economically feasible to manufacture SST with cargo capacities of 4453 m3 and 2203 m3. Furthermore, the results show that the SST is the most cost-effective option for transporting low-volume CO2 (1.5 mtpa) over short distances.

Feasibility analysis and performance characteristic investigation of thermal energy storage system based on organic Rankine cycle for engine exhaust temperature modulation

ABSTRACT The exhaust temperature of the engine has a significant impact on the conversion efficiency of the after-treatment. A thermal energy storage (TES) system with organic fluid for engine exhaust temperature modulation is established in this paper, and the performance characteristics of the TES system with the engine exhaust temperature modulation are analyzed based on the organic Rankine cycle (ORC). First, an accumulator-centered TES system model is established based on GT- SUITE, and the effects of working fluid mass, mass flow rate, supply strategy and working fluid type on the TES system are analyzed. Second, the influence of coupled ORC-TES system on exhaust emission and after-treatment efficiency is analyzed, and the cost–benefit analysis of integrated ORC-TES system is carried out. Finally, the simulation results show that with the increase in working fluid mass, the average temperature, availability, satisfaction, and comprehensive index (CI) of the TES system gradually decrease, while the standard deviation gradually increases. Simultaneously, the average temperature, availability, satisfaction, and CI of the TES system all increase with increasing working fluid mass flow rate for the same mass of working fluid. In the high-performance region (CI = 0.7 ~ 1.0), the modulating performance of exhaust temperature mainly depends on the mass of the working fluid supply. However, in the low-performance region (CI = 0 ~ 0.4), the sensitivity of mass and mass flow should be taken into account. In addition, in the high-performance region, the supply of 4 kg of working fluid at a speed of 1.0 kg/s can also be considered the best solution, and R404a is the most suitable working fluids for thermal energy storage. Under Europe Transient Cycle (ETC), the average temperature, availability, satisfaction, and CI are increased by 2.9%, 7.46%, 34.1%, and 100%, respectively, with the TES system, and the standard deviation is decreased by 53%. Compared to the ORC system, the coupled ORC-TES system leads to an increase in exhaust back pressure (EBP), but does not lead to an increase in fuel consumption due to the improved thermal efficiency of the ORC system. In addition, the integrated ORC-TES system can improve the SCR catalytic efficiency and reduce NOx emissions. From a cost–benefit analysis, the ORC-TES system is practically feasible.

Design and feasibility analysis of an off-grid hybrid energy system to fulfill electricity and freshwater demand: a case study

ABSTRACT The stand-alone hybrid renewable energy system has emerged as a promising route toward reliable and sustainable electrification of isolated islands where grid power cannot be supplied due to techno-economic limitations. In this regard, this article focuses on the design of a system with renewable energy sources and storage facilities to meet the need for freshwater and electricity on Kavaratti Island, Lakshadweep, India. The principal objective of the research is to decrease reliance on the expensive and ecologically detrimental diesel generator (DIG) with the installation of solar-photovoltaic (SPV), wind-energy system (WES), battery-bank (BB), and fuel-cell (FC). In compliance with the Indian government’s recent proposal to build desalination plants (DP) to satisfy the freshwater demands of the islands, this study considers the power consumption of DP. The stochastic load demand of electric vehicle (EV) charging stations is also taken into consideration. Moreover, considering all scenarios that might occur in a real-world system, a smart energy scheduling technique is suggested to maintain energy balance. Furthermore, five different planning configurations are analyzed in detail to identify the most desirable one. The hybrid SPV/WES/BB/FC/DIG system with 1815 kW SPV, 2288 kW WES, 1400 kWh BB, 781 kW FC, and 1003 kW DIG is obtained as the optimal configuration. According to research findings, this system has a cost of energy of 0.186 $/kWh, net present cost of 2.68 × 108 $, and pollutants emission of 53,902.7 tons, which are 80.11%, 76.89%, and 79.14% less than the DIG-only system, respectively. Furthermore, dump energy is found to be the lowest when both BB and FC are installed together, which highlights the importance of combining storage elements to maximize the utilization of renewable energy. Overall, the proposed study recommends LED to design a hybrid energy system with renewable energy sources and storage elements to make considerable financial gains and preserve the ecological diversity of the island.
