Microfog lubricant application system for advanced turbine engine components - Determination of the velocities, particle size distributions, and wettabilities of microfog streams of various lubricants Final report

Determination of velocities, particle size distributions, and wettabilities of microfog streams of various lubricant

Microfog lubricant application system for advanced turbine engine components, phase 1. Tasks 1 and 2 - Wettabilities of microfog streams of various lubricants and optimization of microfog lubrication

Wettability of microfog streams of high temperature lubricants on static metal surfac

Microfog lubricant application system for advanced turbine engine components, phase 2. Tasks 3, 4 and 5: Wettability and heat transfer of microfog jets impinging on a heated rotating disc, and evaluation of reclassifying nozzles and a vortex mist generator

The wettabilities and heat transfer rates of microfog jets (oil-mist nozzle flows) impinging on a heated rotating disc were determined under an inert atmosphere of nitrogen at temperatures ranging from 600 to 800 F. The results are discussed in relation to the various factors involved in the microfog lubricant application systems. Two novel reclassifying nozzles and a vortex mist generator were also studied

Microfog lubricant application system for advanced turbine engine components, phase 3

The wetting characteristics and deposit forming tendencies of a series of lubricants were evaluated using a microfog jet delivery system to wet a flat heated rotating disc. The performances of the nine lubricants are discussed in terms of the various testing parameters which include temperature, disc speed and lubricant gas flow rates. Also discussed are the heat transfer characteristics of two of the lubricants on that same plane disc specimen. The wetting characteristics and heat transfer characteristics of one of the lubricants on a complex disc simulating bearing geometry are also discussed

Perturbative unitarity bounds for effective composite models

In this paper we present the partial wave unitarity bound in the parameter space of dimension-5 and dimension-6 effective operators that arise in a compositeness scenario. These are routinely used in experimental searches at the LHC to constraint contact and gauge interactions between ordinary Standard Model fermions and excited (composite) states of mass $M$. After deducing the unitarity bound for the production process of a composite neutrino, we implement such bound and compare it with the recent experimental exclusion curves for Run 2, the High-Luminosity and High-Energy configurations of the LHC. Our results also applies to the searches where a generic single excited state is produced via contact interactions. We find that the unitarity bound, so far overlooked, is quite complelling and significant portions of the parameter space ($M,\Lambda$) become excluded in addition to the standard request $M \le \Lambda$.Comment: This version of the paper merges the previous version published in Phys.

Agile Gnewt Cargo: parcels deliveries with electric vehicles in Central London Multi-carrier central London micro-consolidation and final delivery via low carbon vehicles. Data Report

This dataset contains the results of the first Agile Urban Logistics trials that were funded by the Mayor of London and delivered by Gnewt Cargo in partnership with the University of Westminster. The Agile Urban Logistics project was delivered under the Mayor’s Smart London Demonstrator programme. The aim was to trial innovative solutions for the light freight sector that allows it to adapt to changing regulatory and market conditions, mitigating congestion and emissions impacts. The three trials were: Agile 1: Multi-carrier consolidation trial In the Agile Gnewt Cargo trial, the demonstrator carried parcels for final delivery in central London for several major parcels businesses (namely Hermes, TNT and DX, all of which are active in business-to-consumer (B2C), home deliveries, and business-to-business (B2B) operations in London and the UK). The area covered focuses around the London Congestion charge area with a keen focus on the west side of this highly polluted region

IT solutions for parcel deliveries with electric vehicles in Central London - Technology-based solution to facilitate efficient allocation and cross-carrier routing. Data Report

This data report contains the results of the second set of Agile Urban Logistics trials that were funded by the Mayor of London and delivered 2015 to 2017 by Gnewt Cargo in partnership with the University of Westminster. The Agile Urban Logistics project was delivered under the Mayor’s Smart London Demonstrator programme. The aim was to trial innovative solutions for the light freight sector that allows it to adapt to changing regulatory and market conditions, mitigating congestion and emissions impacts. Agile 2: IT solutions for parcel deliveries trial The trial was designed to test a range of IT solutions for electric fleet management, improving efficient client communication management and routing and planning systems

Parcel deliveries with electric vehicles in Central London - Category 3: Single carrier consolidation centre targeting poor air quality zones enabling manual delivery methods. Data Report

This Data Report contains the data of the third set of Agile Urban Logistics trials that were funded by the Mayor of London and delivered by Gnewt Cargo in partnership with the University of Westminster in 2015 to 2017. The Agile Urban Logistics project was delivered under the Mayor’s Smart London Demonstrator programme. The aim was to trial innovative solutions for the light freight sector that allows it to adapt to changing regulatory and market conditions, mitigating congestion and emissions impacts. Agile 3: Single-carrier consolidation trial The trial explored scenarios for consolidating deliveries of multiple retail and non- retail clients using a single carrier (Gnewt Cargo) in a single van. All deliveries were done using electric vans. The aim of the trial was to reduce the number of delivery trips, reduce congestion and improve air quality outputs compared to a diesel equivalent approach by utilizing zero emissions electric freight delivery vehicles

Weighted Miranda-Talenti inequality and applications to equations with discontinuous coefficients

summary:Let $\Omega$ be an open bounded set in $\Bbb R^{n}$ $(n\geq 2)$, with $C^2$ boundary, and $N^{p,\lambda}(\Omega )$ ($1 < p < +\infty$, $0\leq \lambda < n$) be a weighted Morrey space. In this note we prove a weighted version of the Miranda-Talenti inequality and we exploit it to show that, under a suitable condition of Cordes type, the Dirichlet problem: \cases \sum_{i,j=1}^n a_{ij}(x) \frac{\partial ^2 u}{\partial x_i \partial x_j} = f(x) \in N^{p,\lambda }(\Omega) \quad & \text{ in } \Omega \ u=0 & \text{ on } \partial \Omega \endcases has a unique strong solution in the functional space $$ \left\{ u \in W^{2,p} \cap W^{1,p}_o(\Omega ) : \frac{\partial ^2 u}{\partial x_i \partial x_j} \in N^{p,\lambda}(\Omega ), i,j=1,2,\,\ldots, n\right\}. $
