Assessing real-world emissions from buses and taxis is vital to comprehend their impact on urban air quality. Such vehicles differ significantly from the majority of the fleet owing to their higher mileage rates. However, few studies have focused on specifically assessing the emissions from this segment of the vehicle fleet. In this context,...

This work demonstrates the efficiency of using iterative ensemble smoothers to estimate the parameters of an SEIR model. We have extended a standard SEIR model with age-classes and compartments of sick, hospitalized, and dead. The data conditioned on are the daily numbers of accumulated deaths and the number of hospitalized. Also, it is possible...

It is widely recognized that future rainfall extremes will intensify. This expectation is tied to the Clausius-Clapeyron (CC) relation, stating that the maximum water vapour content in the atmosphere increases by 6-7% per degree warming. Scaling rates for the dependency of hourly precipitation extremes on near-surface (dew point) temperature...

We introduce the Precipitation Probability DISTribution (PPDIST) dataset, a collection of global high-resolution (0.1°) observation-based climatologies (1979–2018) of the occurrence and peak intensity of precipitation (P) at daily and 3-hourly time-scales. The climatologies were produced using neural networks trained with daily P observations...

This study documents and attempts to describe the processes leading to the formation and preservation of exposed oil, water, and paleo-gas contacts at the McMurray Formation type section, Alberta, Canada. The McMurray Formation type section, a part of the Athabasca Oil Sands Deposit (AOSD), the largest exhumed oil reservoir on Earth, is...

Binding selectivity and cross-reactivity within one of the largest and most abundant interaction domain families, the PDZ family, has long been enigmatic. The complete human PDZ domain complement (the PDZome) consists of 267 domains and we applied here a Bayesian selectivity model to predict hundreds of human PDZ domain interactions, using...

Municipal sewage was placed in geotextile bags for the purpose of evaluating the dewatering and consolidation capabilities of large geotextile tubes and effluent water quality. A proposed AS TM test method for determining the flow rate of suspended solids from a geotextile containment system for dredged material was used to conduct tests to...

As part of the program of studies on centrifugal impellers, the problem of instability at low flows was investigated. The major cause was found to be flow detachment from the impeller vanes. Slotted blades were found to be the most effective means of delaying this detachment, and extending the working range of the blower. Low speed studies were...

The optimization of instalIed power in a low-speed overland ACV is shown to depend heavily on the minimization of skirt/terrain interaction drag, which is in turn shown to depend critically up on lift-air supply. The influence of hoverheight, terrain roughness and porosity, vegetation, and vehicle speed on drag is examined in the light of data...

This handbook of data endeavours to collect and present in practical form such design data relating to performance as are currently publicly available. The art is at present in an early stage of its development, and many of the data given are tentative or incomplete, and are hedged around by ill-defined boundary conditions. We shall attempt to...

In order to overcome disadvantages in existing methods, a new smoke-system for wind tunnels has been investigated. The system consists simply of a device for mixing jets of anhydrous ammonia and sulphur dioxide gases. It is instantly controllable, produces dense white smoke without clogging, is easily portable, and poses no fire risk. Provided...

The patterns and stability of the airflow in the rotor of a centrifugal fan have been studied, with thin plate blading and with thick aerofoil blades. Specifications of the blading are presented, and a detailed comparison is made of the visualised flow patterns in the channels, exit velocity profiles, flow characteristic curves, and operating...

Experiments were carried out on the NRC Low Speed Centrifugal Compressor Rig on a 4-foot - l0½-inch diameter model of a fan impeller with highly swept-back vanes. The impeller was run over a range of speeds and throttle settings to explore the who le operating field. The flow was measured at inlet and impeller exit by hot-wireanemometer...

In a previous series of tests, the character and distribution of flow in the channels of a largescale model of a centrifugal compressor impeller were explored and measured. In order to make a more detailed study of the flow that was thus discovered, a new series of tests was carried out and is described in the present report. The complete rotor...

The flow in the impeller of a centrifugal flow compressor is complex, and is not yet fully understood. A theoretical model of this flow is proposed, from first principles, and an experimental method of investigating the validity of this model is described. An observer is placed in the centre of a large model of the impeller, and by rotating with...
