In this paper, we describe the monitoring of Portand cement paste, with a 0.50 water cement ratio (w/c), during early age period, recurring to optical and electrical techniques. The optical monitoring of the cement paste was realized with FBG temperature sensors, and the temperature variations during the early age period were characterized. The RF values of the cement paste and therefore predic...

This note introduces the use of distributed polarization x-talk measurement for raw polarization maintaining fiber (PMF) quality inspection, PMF coil winding process monitoring, PMF coil adhesive curing and stress release monitoring, overall PMF coil quality inspection, and temperature induced stress determination. PMF birefringence temperature variation can also be precisely measured. The use ...

Wireless sensor networks are used in different fields. One of the fields, where such sensors can be used is apiculture for honey bee (Apis Mellifera L.) monitoring (for example, temperature and humidity data acquisition). This paper introduces a wireless sensor network system for bee colonies online monitoring. The developed wireless system consists of several wireless measurement nodes which t...

We report the development of a versatile microfluidic (MF) reactor with multiple analytical probes, which can be used for (i) quantitative characterisation of molecular vibrational signatures of reactants or products, (ii) the localised real-time monitoring of temperature and (iii) site-specific measurements of pH of the reaction system. The analytical probes utilised for in situ reaction analy...

Diabetic foot complications are associated with substantial costs and loss of quality of life. This article gives an overview of available and emerging devices for the monitoring of foot temperature as a means of early detection of foot disorders in diabetes. The aim is to describe the technologies and to summarize experiences from experimental use. Studies show that regular monitoring of foot ...

In this modern era, every passing day reveals a new invention to the world. Every invention gives us new school of thought and with every invention challenges also increase. We can observe and control the system by using the invention of remote control. To control a system automatically, monitoring is mandatory for efficient control. According to changing setup, control is possible by remote mo...

In the study of granary monitoring, many research projects are involved in environmental monitoring in recent years. However, most existing studies are interested in the outdoor natural environment monitoring. Few of them focus on the indoor monitoring. This paper presents a system based on wireless sensor network (WSN) for granary monitoring including grain temperature and humidity. The whole ...

Convenient and reliable temperature monitoring systems are increasingly demanded in vehicle refrigerators. However, difficulties exist in wiring between temperature recorders and sensors in vehicles such as trailer-tractor. To solve this problem, this paper provides a novel solution: wireless temperature sensors using Bluetooth. A prototype of the wireless temperature sensors has been developed...

This paper presents a resilient cache memory for dynamic variation tolerance in a 40-nm CMOS. The cache can perform sustained operations under a large-amplitude voltage droop. To realize sustained operation, the resilient cache exploits 7T/14T bit-enhancing SRAM and onchip voltage/temperature monitoring circuit. 7T/14T bit-enhancing SRAM can reconfigure itself dynamically to a reliable bit-enha...
