  • A Compact, Low-Power In-Situ Flow Analyzer for Marine Applications

    A New Tool for In-Situ Analysis is Implemented On an Automated Buoy in the Mediterranean Sea Continuous monitoring of highly dynamic systems like coastal waters requires frequent sampling in a precise place in order to catch short-term events that might have a strong impact on the ecosystem, such as exceptional phytoplankton blooms or changes caused by storms. The lack of monitoring ...

  • Improving drowned drainage outlets with submerged orifices

    Drowned outlets are common in riverine areas and sometimes unavoidable. Due to site restrictions, drainage discharge outlets are often submerged as the water level fluctuates during high tides or during the monsoon. As the runoff cannot be discharged through the outlet the drainage system fills up faster, leading to flash floods caused by overspill from the drains. This study is focused on the ...

  • The Plumbing of Adaptation Finance - Accountability, Transparency, and Accessibility at the Local Level

    Adaptation is local but reaching the local level is not always easy. This paper explores the challenges of reaching the most vulnerable people with adaptation finance. It identifies opportunities for improvement and proposes a framework to assess delivery of adaptation finance focusing on transparency, ownership, responsiveness and equity. The amount of international climate finance approved to ...

  • Material flows of end-of-life home appliances in Japan

    In Japan, the Law for the Recycling of Specified Kinds of Home Appliances came into effect in April 2001. This law aims to introduce appropriate waste treatment and promote the efficient use of resources so that we can achieve a sound material-cycle society. The law introduces a new framework for recycling that places obligations principally on the manufacturers and retailers of home appliances. ...

  • Drawing into Bloodless Health Monitors

    A team of scientists at the University of California, Berkeley developed a wearable sensor to monitor an individual’s health based upon their sweat. The sensor is constructed as a patch with a spiral-patterned microfluidic component where sweat samples can flow and be analyzed.[1] It has shown potential for monitoring sodium and fluid loss, and ...

  • Implication of climate change and variability on stream flow in Iringa region, Tanzania

    This paper investigates the implication of climate change and variability on the river flow within the traditional irrigation farming system, vinyungu, in Iringa region, Tanzania. The study aimed at establishing areas that are most impacted by climate change in terms of river flow and various adaptation strategies. It is based on both primary data collected by questionnaires distributed ...

  • Tourism, residents' attitudes and perceived carrying capacity with an experimental study in five Tuscan destinations

    This paper starts from the idea that tourism is an encounter of at least two non-homogeneous populations: residents and tourists. Their interaction may trigger conflicts and a population dynamics whose results are difficult to foresee. It follows that the sustainability of tourism depends simultaneously upon the sustainable use of local resources and the minimisation of the costs of conflict ...

  • Removal of persistent organic pollutants from landfill leachates treated in three constructed wetland systems

    The objective of the study was assessment of occurrence and removal of two groups of persistent organic pollutants: polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) in landfill leachate (LL) treated in three constructed wetland systems (CWs) of different construction and flow regime. Two subsurface flow systems (SSF) were analyzed: one with horizontal flow and the ...

  • Comparative Evaluation of Test Methods for Reciprocating Engines; EPA Reference Methods vs. Portable Analyzer

    Abstract This is a comparative evaluation of errors in testing engines using reference methods and portable analyzers. New Mexico Environment Department (NMED) Air Quality Bureau has published a guidance document, Standard Operating Procedure (SOP), Use of Portable Analyzers in Performance Tests. EPA provides guidance on reference method testing in 40 CFR 60, Appendix A. This document is ...

  • The intermodal and noncontainerised supply chain connecting Northern Europe to North America

    Intermodality is often discussed in the research literature from the point of view of containerised transports. This paper illustrates an intermodal and noncontainerised supply chain solution through the case of a Finnish paper producing company. The supply chain connecting Northern Europe to North America is analysed with respect to different transportation modes and product flows throughout the ...

  • Exchange rate (volatility) and bilateral agricultural trade: Turkey vs. her major trading partners

    The purpose of this study is to analyse the sensitivity of Turkish bilateral agricultural trade flows to exchange rate and its volatility. To this end, we estimate the bilateral export, import and trade balance equations between Turkey and her 16 major trading partners for the period of 1987:q1-;2007:q4 by utilising the Vector Error Correction Modelling (VECM) framework. The short-run analysis ...

  • Indicating inter-industrial knowledge flows: example of Korea

    Despite the importance of active inter-industrial knowledge flows for national competitiveness, there has been no appropriate indicator through which the patterns of inter-industrial knowledge flow can be examined. Therefore, in this research, we propose various indicators that enable us to comparatively analyse industries in terms of knowledge flow. As proxy measures for knowledge, we make use ...

  • Automated feature recognition in CFPD analyses of DMA or supply area flow data

    The recently introduced comparison of flow pattern distributions (CFPD) method for the identification, quantification and interpretation of anomalies in district metered areas (DMAs) or supply area flow time series relies, for practical applications, on visual identification and interpretation of features in CFPD block diagrams. This paper presents an algorithm for automated feature ...

  • The internal entrepreneur as a catalyst to successful product development: a case study

    Product development is an essential part of the total innovation process. This paper describes some of the elements that are indispensable for successful product development. The advancement of the circuit breaker, a product that is used to make or break the flow of electrical current, is analysed over a period of almost 30 years. During this time, it becomes clear that continuous improvement in ...

  • SmartMeter™ Case Study: Tinley Park, Illinois

    A few years after the initial SmartMeters were installed, the village needed to have the remaining meters replaced.Rather than make a snap decision, village officals decided to undertake a detailed cost benefit analysis to determinethe best solution.This consisted of two steps: a theoretical calculation of the loss of revenue from the mechanicalmeters, and an analysis of the actual earning ...

  • Flow characteristics of individual lot stormwater detention

    In this paper the flow characteristics of stormwater are analyzed as it travels from a roof gutter down-pipe and the turbulent flow generated on entering an individual lot on-site stormwater detention (OSD) unit beneath a residential carport. Comparison was made between a full-scale model and computational fluid dynamic (CFD) simulations to determine the flow characteristics. These modular ...

  • Sensitivity analysis of bridge pier scour depth predictive formulae

    Sensitivity analysis is an approach to recognising the behaviour of models and relative importance of causative factors. In this paper, behaviours of six pier scour depth empirical formulae are evaluated on the basis of an analytical method. The sensitivity of predicted scour depth is analysed with respect to the following independent parameters: approach flow depth, riverbed slope and median ...

  • Improving flow distribution in influent channels using computational fluid dynamics

    Although the flow distribution in an influent channel where the inflow is split into each treatment process in a wastewater treatment plant greatly affects the efficiency of the process, and a weir is the typical structure for the flow distribution, to the authors' knowledge, there is a paucity of research on the flow distribution in an open channel with a weir. In this study, the influent ...
