  • Detect Leaks and Analyze Water Consumption with WaterSignal

    Did you know it will cost an estimated $1 trillion over the next 25 years to upgrade the nation’s water system to run more efficiently? While part of the problem is fragile, hundred-year-old water mains, it also falls on property owners to ensure they are doing their part to save water — for both the environment and their wallets. But how? ...

  • Nuclear self esteem

    Being technically multifaceted and complex for understanding by the general public, the capability of some nuclear applications, especially nuclear power, and their potential in helping with some of the most important global issues, seem to be underrated by the public. A few elements that are responsible for this 'higher complexity lengthier pipeline' from demonstrated performance to public ...

  • Gravity self-backwashing filters

    The filtration of make-up and side-stream water in closed cooling circuits, operated through cooling towers, is a fundamental step to ensure safe and continuous operations in a power plant. Water - required in large amounts for this application - should not be wasted, and the potential damages deriving from a poor treatment must be avoided at all cost. BONO ARTES has developed a technical ...

  • A Self-Boring Pressuremeter System

    The paper describes some of the development work on the Cambridge University version of the self-boring pressuremeter (the so-called “Camkometer”), which has been carried out at the University of Western Australia over a number of years. This work included improvement of the pore-pressure measuring system and development of a deairing system for the pore-pressure transducers, new supply-voltage ...

  • The Basics of EH&S Self-Auditing

    The challenge of complying with all of the applicable environmental and occupational safety regulations is formidable for any organization. Internal auditing, or self-auditing, is increasingly being used to address this challenge. This article looks at the range of auditing practices that exist to help organizations decide if self-auditing makes sense for them and what form it should take. ...

  • Exploring a quality of life, self-determined

    Built capital combines with social, personal and natural capital to contextualize people's quality of life. Although this last concept has strongly tested academic reasoning, it is often presented simply and as a fait accompli in strategic planning documents. This article questions these pragmatic 'top-down' scripts by engaging the self-determination theory of motivation. It argues the transience ...

  • Array gain and reduction of self-noise

    Abstract—Because an array is composed of many sensors, each making an independent measurement of the wavefield, intelligent combination of the sensor signals should lead to an overall increase in the signal-to-noise ratio. What we are trying to achieve is enhancing the signal with an array beyond what is possible with a single sensor. The array gain measures an array’s signal-to-noise ...

  • Are self-driving vehicles good for the environment?

    Autonomous transportation has lots of advantages. Reducing greenhouse gas emissions could be one of them. Can autonomous cars be a boon for the environment? The transportation sector is the second largest source of greenhouse gas emissions in the United States, accounting for 27 ...

  • Nucleation phenomenon in nanoparticle self-assemblies

    Dispersed nanoparticles self-assemble into complex structures when segregated from the solvent either by evaporation or precipitation. Thus, different micro- and macroscopic structures (opals, fractals, liquid crystals) formed by nanoparticles are observed as a result of the balance between electrostatic forces, surface tension, volume exclusion, substrate topography and affinity, and size, shape ...

  • An infrastructure for developing self-organising services

    This paper describes a software package named 'licas' (lightweight internet-based communication for autonomic services) that can be used to build networks of service-based components that have the potential to behave autonomously and self-organise through stigmergic links. Discussed will be how these components are able to self-adapt inside of this infrastructure and also show potential for more ...

  • SeReCon: a secure reconfiguration controller for self-reconfigurable systems

    A risk of covert insertion of circuitry into reconfigurable computing (RC) systems exists. This paper reviews risks of hardware attack on field programmable gate array (FPGA)-based RC systems and proposes a method for secure system credentials generation (unique, random and partially anonymous) and trusted self-reconfiguration, using a secure reconfiguration controller (SeReCon) and partial ...

  • Submersible Pumps vs. Self-Priming Centrifugal Pumps

    When selecting a centrifugal pump for bypass work, the first consideration should be NPSHR by the pump. Neglecting the NPSHR of the pump is the single most common mistake when choosing a self-priming or priming assisted pump. A function of the pump design requires part of the 33.9 ft (14.7 in.) available as further defined in this article. A centrifugal, and in a way submersibles, require part ...

  • Process audit: from compliance to self-management

    In the past decade we have seen phenomenal improvements in the New Product and Service Introduction processes (NPSI). Applications of tools and methods, and use of process and quality management approaches have enabled companies to reduce continuously their cycle time, introduce products faster, cheaper, with higher quality, and better satisfy market needs. Among the enabling technologies, audits ...

  • Inverse infrastructures: self-organization in the water services

    In urban communities, infrastructures that support living are indispensable. There is increased interest in alternative ways of providing such support systems, including semi-autonomous infrastructures resulting from the self-organization of local actors. In this study, we analyze the emergence and management of such infrastructures in light of the theory of complex adaptive systems, within ...

  • Self–organised growth of molecular arrays at surfaces

    The autonomous ordering and assembly of atoms and molecules on atomically well–defined surfaces allow creating a wide range of surface nanostructures, opening an alternative ‘bottom–up’ route to the traditional ‘top–down’ fabrication methods of the microelectronics industry now approaching their fundamental limits. This review summarises some recent efforts of our team to grow molecular arrays on ...

  • Development of a self-rechargeable digital water flow meter

    The objective of this paper is to present the feasibility of a self-rechargeable digital water flow meter (SRDFM) system for water pipes using the latest data processing and wireless communication technologies while causing negligible water pressure drop (head loss). The system uses a Pelton turbine generator to power the electronic circuit, which processes and transmits the signals generated by ...

  • Directed self-organisation of soluble proteins on surfaces

    Incorporation of proteins on surfaces is a first step in the lengthy process of using active biological molecules in man-made nanodevices. There is therefore a strong motivation to develop strategies for organising active proteins on solid substrates and it is very desirable to take advantage of the principles of self-assembly. In the present work, I summarise two strategies to orient and ...
