Selecting control schemes and tuning rules in feedforward control

This paper treats the problem of feedforward control from measurable load disturbances. Most of the tuning rules based on IAE or ISE optimization for feedforward compensators that have been presented in recent years are compared with each other as well as with optimal compensators. There are two different feedforward control schemes that may be used, and these schemes are also compared and analyze

Multivariable control of nighttime temperature and humidity in greenhouses combining heating and dehumidification

This work presents a multivariable control strategy to regulate nighttime temperature and relative humidity inside a greenhouse, using a pipe heating system and a dehumidification system. The greenhouse is modeled as a two-input two-output (TITO) process with a system identification methodology to calculate low-order linear models. Proportional-integral (PI) controllers with anti-windup are used,

Cultivating resilience and hope: A qualitative study of a pilot program using patient navigators to assist men who have sex with men with retention in the HIV care continuum in Uganda : A qualitative study of a pilot program using patient navigators to assist men who have sex with men with retention in the HIV care continuum in Uganda

In Uganda, due to the criminalization of same-sex sexual practices, men who have sex with men (MSM) experience barriers to accessing HIV care. To retain patients within the HIV Care Continuum, some health interventions have used patient navigators as an ancillary support service. To understand the potential care benefits of using patient navigators for marginalized populations experiencing challen

Survival in patients diagnosed with melanoma in situ compared to the general population. A Swedish population-based matched cohort study

Background: The incidence of melanoma in situ (MIS) is increasing even more rapidly than the incidence of cutaneous malignant melanoma (CMM). No previous studies have in detail investigated the survival in individuals diagnosed with MIS compared to the general population. Methods: This population-based study included individuals with MIS diagnosed in Sweden between 2001 and 2010 and randomly selec

Generation of the iPSC line FINi002-A from a male Parkinson's disease patient carrying compound heterozygous mutations in the PRKN gene

The most common cause of autosomal recessive familial Parkinson's disease (PD) are mutations in the PRKN/PARK2 gene encoding an E3 ubiquitin protein-ligase PARKIN. We report the generation of an iPSC cell line from the fibroblasts of a male PD patient carrying a common missense variant in exon 7 (p.Arg275Trp), and a 133 kb deletion encompassing exon 8, using transiently-present Sendai virus. The e

Emerging threats and opportunities to managed bee species in European agricultural systems : a horizon scan

Managed bee species provide essential pollination services that contribute to food security worldwide. However, managed bees face a diverse array of threats and anticipating these, and potential opportunities to reduce risks, is essential for the sustainable management of pollination services. We conducted a horizon scanning exercise with 20 experts from across Europe to identify emerging threats

Simulating Energy Renovation Towards Climate Neutrality. Digital Workflows and Tools for Life Cycle Assessment of Collective Housing in Portugal and Sweden

This chapter compares two digital workflows and tool selection for best practice renovation simulation in Portugal and Sweden. Both workflows are part of ongoing research projects that seek to provide a robust workflow adapted to different user needs and scale implementation. While in Portugal, the focus is on the building, the assessment is scaled up to the neighbourhood in Sweden. Geographic inf

Multivariable prediction models of caries increment : a systematic review and critical appraisal

Background: Multivariable prediction models are used in oral health care to identify individuals with an increased likelihood of caries increment. The outcomes of the models should help to manage individualized interventions and to determine the periodicity of service. The objective was to review and critically appraise studies of multivariable prediction models of caries increment. Methods: Longi

An ultralow-temperature cascade refrigeration unit with natural refrigerant pair R290-R170 : Performance evaluation under different ambient and freezing temperatures

The global demand for ultralow-temperature (ULT) refrigeration units gets greatly promoted, for storage, transportation, and distribution of COVID-19 vaccines. In this work, a ULT freezer is developed with a cascade refrigeration system (CRS) utilizing environmentally friendly refrigerants R290 and R170. The performance of the ULT freezer is experimentally evaluated under different ambient tempera

The rise and fall of the Malvinoxhosan (Malvinokaffric) bioregion in South Africa : Evidence for Early-Middle Devonian biocrises at the South Pole

Global reconstructions, inclusive of environments and ecosystems, and biodiversity counts for the Devonian Period are often done so at the expense of high latitude regions given a historical lack of data presented from these areas. This has bearing on the recognition of biocrises (events marked by extinctions and faunal turnovers) at high latitudes as well as their controls and potential correlati

To what extent are greenhouse-gas emissions offset by trees in a Sahelian silvopastoral system?

To assess the extent to which trees in a semi-arid silvopastoral system (SPS) can offset the greenhouse-gas (GHG) emissions of the system's livestock, this study used two process-based models (STEP-GENDEC-N2O and DynACof) to simulate 9 years of agricultural activity and resulting emissions in a SPS that has been operating in sahelian Senegal. STEP-GENDEC-N2O simulated soil N2O and CO2 fluxes, plus

Diffusion MRI with free gradient waveforms on a high-performance gradient system : Probing restriction and exchange in the human brain

The dependence of the diffusion MRI signal on the diffusion time carries signatures of restricted diffusion and exchange. Here we seek to highlight these signatures in the human brain by performing experiments using free gradient waveforms designed to be selectively sensitive to the two effects. We examine six healthy volunteers using both strong and ultra-strong gradients (80, 200 and 300 mT/m).

Assessing the risks and opportunities posed by AI-enhanced influence operations on social media

Large language models (LLMs) like GPT-4 have the potential to dramatically change the landscape of influence operations. They can generate persuasive, tailored content at scale, making campaigns using falsified content, such as disinformation and fake accounts, easier to produce. Advances in self-hosted open-source models have meant that adversaries can evade content moderation and security checks

Dude, Where's My Car? Cellular Navigation for Autonomous Driving

Position and direction estimation is useful for numerous engineering applications for commercial, scientific, and military purposes. Technology that fuses observations of signals broadcast by Global Navigational Satellite Systems (GNSS) with inertial measurements is standard for electronic devices, but this requires at least a periodically unobstructed view of the sky to perform reliably. This has

Skapa Demokrati

Projektet är framtaget i samarbete med forskningsstiftelsen Institutet för framtidsstudier och ingår forsknings- och utvecklingsarbetet kring nya sceniska berättarformat på Teaterhögskolan i Malmö.

Measurement of the radius dependence of charged-particle jet suppression in Pb–Pb collisions at sNN=5.02TeV

The ALICE Collaboration reports a differential measurement of inclusive jet suppression using pp and Pb–Pb collision data at a center-of-mass energy per nucleon–nucleon collision sNN=5.02 TeV. Charged-particle jets are reconstructed using the anti-kT algorithm with resolution parameters R=0.2, 0.3, 0.4, 0.5, and 0.6 in pp collisions and R=0.2, 0.4, 0.6 in central (0–10%), semi-central (30–50%), an

Observation of WZγ Production in pp Collisions at sqrt[s]=13 TeV with the ATLAS Detector

This Letter reports the observation of WZγ production and a measurement of its cross section using 140.1±1.2 fb^{-1} of proton-proton collision data recorded at a center-of-mass energy of 13 TeV by the ATLAS detector at the Large Hadron Collider. The WZγ production cross section, with both the W and Z bosons decaying leptonically, pp→WZγ→ℓ^{'}^{±}νℓ^{+}ℓ^{-}γ (ℓ^{(^{'})}=e, μ), is measured in a fi
