Abstract

Purpose

The purpose of this paper is to examine the design and capabilities of data acquisition systems, and review various interesting applications.

Design/methodology/approach

After a technical and market overview, a series of different applications is presented along with appropriate hardware and software.

Findings

Data logging over an extended period helps diagnose intermittent faults. Connectivity to PCs or remote networks is now an important feature of data loggers, and sophisticated logging stations gather data automatically and control floods and fires. Some tiny devices are available for in situ food and pharmaceuticals monitoring.

Originality/value

This paper shows how an apparently routine engineering tool takes many different forms and tackles exciting applications.

Abstract

This paper responds to recent calls for deeper scrutiny of the institutional contexts of citizen science. In the last few years, at least two dozen civil society organizations in New York and Pennsylvania have begun monitoring the watershed impacts of unconventional natural gas drilling, also known as “fracking.” This study examines the institutional logics that inform these citizen monitoring efforts and probes how relationships with academic science and the regulatory state affect the practices of citizen scientists. We find that the diverse practices of the organizations in the participatory water monitoring field are guided by logics of consciousness-raising, environmental policing, and science. Organizations that initiate monitoring projects typically attempt to combine two or more of these logics as they develop new practices in response to macro-level social and environmental changes. The dominant logic of the field remains unsettled, and many groups appear uncertain about whether and how their practices might have an influence. We conclude that the impacts of macro-level changes, such as the scientization of politics, the rise of neoliberal policy ideas, or even large-scale industrial transformations, are likely to be experienced in field-specific ways.

Abstract

Purpose

The purpose of this paper is to find out tourism movement patterns via the tracking of tourists with the help of positioning systems like GPS in the rural area of the Lake Constance destination in Germany. In doing so past, present and future of tourist tracking is illustrated.

Design/methodology/approach

The tracking is realized via common smartphones extended by an app, with dedicated sensors like position loggers and a survey. The three different approaches are applied in order to compare and cross-check results (triangulation of data and methods).

Findings

Movement patterns turned out to be diverse and individualistic within the rural destination of Lake Constance and following an ants trail in sub-destinations like the city of Constance. Repeat visitors and first-time visitors alike always visit the bigger cities and main day-trip destinations of the Lake. A possible prediction tool enables new avenues of governing tourism movement patterns.

Research limitations/implications

The tracking techniques can be developed further into the direction of “quantified self” using gamification in order to make the tracking app even more attractive.

Practical implications

An algorithm-based prediction tool would offer new perspectives to the management of tourism movements.

Social implications

Further research is needed to overcome the feeling of invasiveness of the app to allow tracking with that approach.

Originality/value

This study is original and innovative because of the first-time use of a smartphone app in tourist tracking, the application on a rural destination and the conceptual description of a prediction tool.

Abstract

During the transport of perishable goods it is important to ensure that optimum temperature storage conditions are observed. To ensure compliance to these conditions a miniature temperature data logger has been developed that can be included in the consignment to sample and record the temperature of the goods in storage and transit. The recorded information can later be retrieved and processed by computer when the goods reach their destination. To meet the required specifications (size and weight in particular) the data logger was constructed using thick film hybrid circuitry built onto a porcelain enamelled steel (PES) substrate plus the use of a custom gate array. The design concept of the data logger and its construction are described and various problems experienced with the PES technology are discussed.

Abstract

Purpose

This work analyzes a pharmaceutical supply chain (PSC) in terms of supply chain visibility (SCV). The current good distribution practice (GDP) guideline demands increased visibility from firms. The purpose of this paper is to propose a solution for SCV enhancements based on automatic identification (Auto-ID) technologies.

Design/methodology/approach

The authors qualitatively analyze data from ten case studies of actors in a PSC. A review of Auto-ID technologies supports the derivation of solutions to enhance SCV.

Findings

This work shows that the functionalities of Auto-ID technologies offered by current practical monitoring solutions and challenges created by the GDP guideline necessitate further SCV enhancements. To enhance SCV, the authors propose three solutions: securPharm with passive radio frequency identification tags, transport containers with sensor nodes, and an SCV dashboard.

Research limitations/implications

This study is limited to a PSC in Germany and is therefore not intended to be exhaustive. Thus, the results serve as a foundation for further analyses.

Practical implications

This study provides an overview of the functionality of Auto-ID technologies. In juxtaposition with the influence of the GDP guideline, the use of our Auto-ID-based solutions can help to enhance SCV.

Originality/value

This work analyzes a PSC in Germany, with consideration given to the influence of current legislation. Based on a multiple-case-study design, the authors derive three Auto-ID-based solutions for enhancing SCV.

Abstract

Purpose

The aim of this paper is to develop a technique to measure the oil film thickness between piston ring and liner throughout the stroke, without impairing the surface properties of the piston ring and liner. Mechanical properties of the piston ring, like ring stiffness, are also not altered. Effect of variation in bore on the movement of piston ring can be studied with the proposed technique.

Design/methodology/approach

The gap Hmin between the cylinder liner and the piston ring is formed due to the hydrodynamic pressure generated by the presence of oil film between piston ring and liner. This gap can be inferred by measuring the movement of the inner surface of piston ring with reference to a sensor mounted on the piston at a fixed distance from the piston ring. The piston ring is connected to the sensor through reasonably rigid member. The underlying assumption here is that there is no elastic deformation of the piston ring due to the hydrodynamic pressure. The fundamental sensor to measure oil film thickness used in this setup is a set of strain gauges.

Findings

It is possible to measure oil film thickness by the proposed arrangement for the entire stroke without changing the surface properties. Mechanical properties of the piston ring, like ring tension, are not affected. The results possibly provide the correct picture of the piston ring movement throughout the stroke. The measurement at near zero speed can give information on the movement of the piston ring due to hydrodynamic action and to the variation in the bore. The measurement is not affected by engine vibrations. The proposed technique can be helpful in validating the theoretical models proposed in the literature.

Originality/value

The measurement is possible only in unfired condition. However, this attempt can be considered as the basis to measure OFT in fired condition with necessary improvements. It is not feasible to measure quantity of lubricant/extent of lubricant on leading or trailing edge of piston. Effect of temperature on the oil film thickness cannot be studied as the engine is not fired. It is assumed that the piston ring does not pass through elasto‐hydrodynamic lubrication regime. Debris/worn out particles in the oil may affect the indicated oil film thickness at local points.

– The purpose of this study was to examine lighting systems at 77 laboratories located within one building to save energy and associated costs.

Abstract

Purpose

The purpose of this study was to examine lighting systems at 77 laboratories located within one building to save energy and associated costs.

Design/methodology/approach

Field measurements of illumination were conducted and compared to lighting standards and industry recommendations.

Findings

For energy and cost saving, de-lamping all four-lamp luminaires down to two-lamp luminaires and installing occupancy sensors in all laboratories were recommended.

Research limitations/implications

The research team’s project working hours and study period were limited. This study begins to fill the gap in the literature regarding lighting field studies.

Practical implications

By carefully considering light level recommendations, industry standards and installation budgets, existing facilities can install appropriate retrofits to save energy and money without sacrificing illumination levels. Recommended retrofits are anticipated to significantly curtail annual federal energy consumption practices at the labs.

Social implications

The retrofits recommended in this study will reduce US federal government’s energy-related expenditures and greenhouse gas emissions in support of the 2010 Presidential Mandate. The proposed occupancy sensors are anticipated to compensate for humans’ failure to manually control lighting.

Originality/value

This field study adds value by documenting cost-effective methods to measure, record and manage laboratory lighting, and it calls for the implementation of social, economic and ecological interventions. The recommended retrofits will reduce US federal government’s energy-related expenditures and greenhouse gas emissions in support of the 2010 Presidential Mandate.

Abstract

Pressure‐sensor miniaturization requires high‐density packaging. This means that designers are constantly faced with all kinds of challenging, and sometimes impossible, requirements. In this paper we will present three examples with specific technologies and aspects of miniaturization and packaging. The first example is a pressure switch, the second a pressure sensor and the third a smart pressure sensor.
