Real-time exhaust gas modular flowmeter and emissions reporting system for mobile apparatus

A real-time emissions reporting system includes an instrument module adapted to be detachably connected to the exhaust pipe of a combustion engine to provide for flow of exhaust gas therethrough. The instrument module includes a differential pressure probe which allows for determination of flow rate of the exhaust gas and a gas sampling tube for continuously feeding a sample of the exhaust gas to a gas analyzer or a mounting location for a non-sampling gas analyzer. In addition to the module, the emissions reporting system also includes an elastomeric boot for detachably connecting the module to the exhaust pipe of the combustion engine, a gas analyzer for receiving and analyzing gases sampled within the module and a computer for calculating pollutant mass flow rates based on concentrations detected by the gas analyzer and the detected flowrate of the exhaust gas. The system may also include a particulate matter detector with a second gas sampling tube feeding same mounted within the instrument module

Barriers to the Development and Progress of Entrepreneurship in Rural Pakistan

Purpose: Focussing on entrepreneurs’ experiences inhibiting them from launching a business – at the micro level – the purpose of this paper is to identify issues that limit rural entrepreneurship in Pakistan and also, to identify the cultural, social, economic and religious traditions and settings that discourage entrepreneurship thus hindering economic development Design/methodology/approach: An ethnographic approach was used to obtain a picture of current problems and perspectives of rural inhabitants. Members of 84 families were interviewed. Findings: Religious, socioeconomic and structural forces play a significant role in suppressing social and cultural capital in rural areas of Pakistan, explaining the low level of entrepreneurship in these areas. Social and cultural capital requires a certain socioeconomic context for entrepreneurship to thrive. Originality/value: This study examines the determinants of very low levels of entrepreneurship in rural settings in the agro-based regions of interior Sindh, Pakistan; this contributes to the gap of understanding the context of rural entrepreneurs in agro-based economies. This study makes recommendations for policy makers to promote entrepreneurship in such areas

Is er ruimte voor wonen? Reactie op het Ruimte voor Wonen-rapport

Het in april 2020 verschenen rapport Ruimte voor Wonen (RvW) maakt deel uit van de Brede Maatschappelijke Heroverwegingen van kabinet Rutte III. Over de volle breedte van de collectieve sector zijn zestien maatschappelijke opgaven geïdentificeerd, waarvoor implicaties van diverse beleidsopties in kaart worden gebracht. Het uiteindelijke doel is om in de toekomst onderbouwde keuzes mogelijk te maken door inzicht te verschaffen in effectieve beleids- en uitvoeringsopties en de mogelijke gevolgen daarvan. Het is goed nieuws dat er een rapport ligt met een weloverwogen analyse van de huidige problemen en opties voor de toekomst. Op 17 maart 2021 vinden Tweede Kamerverkiezingen plaats. Wonen staat hoog op de politieke agenda en speelt straks vermoedelijk een belangrijke rol in de formatie. Het RvW-rapport biedt een basis voor geïnformeerde beleidsvorming, maar die basis is helaas nog onvolledig. Het 1M Homes-initiatief van de Faculteit Bouwkunde van de TU Delft wil een bijdrage leveren aan een visie op de toekomstige woonopgave. Allereerst door te reageren op de diagnose en de opties voor de toekomst uit het RvW-rapport. De kern van dit commentaar is dat RvW een redelijk gefocust, maar beperkt, perspectief biedt. Het is volgens ons van groot belang voor de lange termijn om die blik te verbreden: het gaat niet alleen om nieuwbouw, maar zeker ook over aanpassing van de bestaande woningvoorraad, de verdeling van de bestaande woonruimte, de kwaliteit van de woonomgeving en bredere welvaartseffecten van verstedelijking

Gross job flows and wage determination in the U.K.: Evidence from firm level data.

This thesis studies important evolutions in three areas in labour economics: the flow approach, the efficiency wage hypothesis and unions. In part one I discuss gross job flows in the U.K., while part II is concerned with wage determination and firm performance. I give an introduction in chapter I where I motivate the study of gross job flows and I highlight the importance of spillovers from the product market to the labour market and vice versa. In chapter II I analyze a pattern of gross job creation and destruction in the U.K. during the 70's and early 80's. At any point in time and even within narrowly defined sectors simultaneous creation and destruction of jobs is observed, the latter being more variable over the cycle. Gross job reallocation, defined as the sum of gross job creation and destruction, is counter cyclical. Chapter III explores the relationship between firm size and job creation and destruction. The largest firms create and destroy most jobs. However, in percentage terms the gross job creation rate is largest in small firms, while the gross job destruction rate is lowest. I further investigate the size distribution dynamics and find that in the long run firms converge towards their average size, while plants do not. The final chapter of part I compares gross job flows across countries and shows the difficulties involved in making a consistent comparison. In part II I analyze vertical spillovers from the labour market to the product market and vice versa. I show that there exists a positive relationship between the wage paid in the firm and its market share performance, only under the hypothesis of efficiency wages. The theory is supported by evidence from firm level panel data. I show that important new insights may be obtained if the product market is explicitly taken into account when analyzing labour problems. Finally, in chapter VI I investigate the impact of unions on employment growth in the U.K. and find that unions have a negative effect on employment growth, but a positive effect on employment levels, although this effect is not robust with respect to time. Moreover, the union effect is weaker the more competitors the firm faces

FootbOWL: Using a generic ontology of football competition for planning match summaries

The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-642-21034-1_16Proceedings of 8th Extended Semantic Web Conference, ESWC 2011, Heraklion, Crete, Greece, May 29-June 2, 2011We present a two-layer OWL ontology-based Knowledge Base (KB) that allows for flexible content selection and discourse structuring in Natural Language text Generation (NLG) and discuss its use for these two tasks. The first layer of the ontology contains an application-independent base ontology. It models the domain and was not designed with NLG in mind. The second layer, which is added on top of the base ontology, models entities and events that can be inferred from the base ontology, including inferable logico-semantic relations between individuals. The nodes in the KB are weighted according to learnt models of content selection, such that a subset of them can be extracted. The extraction is done using templates that also consider semantic relations between the nodes and a simple user profile. The discourse structuring submodule maps the semantic relations to discourse relations and forms discourse units to then arrange them into a coherent discourse graph. The approach is illustrated and evaluated on a KB that models the First Spanish Football League

Extraction of soil solution by drainage centrifugation-effects of centrifugal force and time of centrifugation on soil moisture recovery and solute concentration in soil moisture of loess subsoils.

The solute concentration in the subsoil beneath the root zone is an important parameter for leaching assessment. Drainage centrifugation is considered a simple and straightforward method of determining soil solution chemistry. Although several studies have been carried out to determine whether this method is robust, hardly any results are available for loess subsoils. To study the effect of centrifugation conditions on soil moisture recovery and solute concentration, we sampled the subsoil (1.5-3.0 m depth) at commercial farms in the loess region of the Netherlands. The effect of time (20, 35, 60, 120 and 240 min) on recovery was studied at two levels of the relative centrifugal force (733 and 6597g). The effect of force on recovery was studied by centrifugation for 35 min at 117, 264, 733, 2932, 6597 and 14,191g. All soil moisture samples were chemically analysed. This study shows that drainage centrifugation offers a robust, reproducible and standardised way for determining solute concentrations in mobile soil moisture in silt loam subsoils. The centrifugal force, rather than centrifugation time, has a major effect on recovery. The maximum recovery for silt loams at field capacity is about 40%. Concentrations of most solutes are fairly constant with an increasing recovery, as most solutes, including nitrate, did not show a change in concentration with an increasing recovery

Performance of bull bars in pedestrian impact tests

Thirteen bull bars and the five models of vehicle were tested to measure their performance in pedestrian impact tests. Three tests were used in the assessment: two tests using an impactor representing the upper leg of an adult pedestrian, and a test with an impactor representing the head of a child. The headform impact and one of the upper legform impacts were with the top rail of the bull bar, and the second upper legform impact was with the bumper section of the bull bar. Equivalent locations on the vehicle that the bull bars were attached to were also tested. The tests were conducted at 30 km/h. Two rating systems were developed to summarise the results. The first rates the performance of the bull bars and the fronts of the vehicles according to the New Car Assessment Program consumer rating system used in Europe and Australia. The second system rates the performance of the bull bars relative to the front of the vehicle to which they are attached. Overall, steel bull bars are significantly more hazardous for a pedestrian in the event of a collision than the front of the vehicle, as are the aluminium/alloy bull bars, but to a lesser extent than the steel bull bars. Overall, the polymer bull bars slightly improve the safety of the front of the vehicle.. This study demonstrates the practicability of reporting the performance of bull bars in pedestrian impact tests. The system developed herein could form the basis of a consumer-oriented bull bar testing program.R.W.G. Anderson, A.L. van den Berg, G. Ponte, L.D. Streeter and A.J.

Widely Tunable Quantum-Dot Source Around 3 μm

We propose a widely tunable parametric source in the 3 μm range, based on intracavity spontaneous parametric down conversion (SPDC) of a quantum-dot (QD) laser emitting at 1.55 μm into signal and idler modes around 3.11 μm. To compensate for material dispersion, we engineer the laser structure to emit in a higher-order transverse mode of the waveguide. The width of the latter is used as a degree of freedom to reach phase matching in narrow, deeply etched ridges, where the in-plane confinement of the QDs avoids non-radiative sidewall electron-hole recombination. Since this design depends critically on the knowledge of the refractive index of In1−xGaxAsyP1−y lattice matched to InP at wavelengths where no data are available in the literature, we have accurately determined them as a function of wavelength (λ = 1.55, 2.12 and 3 μm) and arsenic molar fraction (y = 0.55, 0.7 and 0.72) with a precision of ±4 × 10−3. A pair of dichroic dielectric mirrors on the waveguide facets is shown to result in a continuous-wave optical parametric oscillator (OPO), with a threshold around 60 mW. Emission is tunable over hundreds of nanometers and expected to achieve mW levels
