Abstract:

Sensors on autonomous vehicles have inherent physical constraints. To address these limitations, several studies have been conducted to enhance sensing capabilities by establishing wireless communication between infrastructure and autonomous vehicles. Various sensors are strategically positioned within the road infrastructure, providing essential sensory data to these vehicles. The primary challenge lies in sensor placement, as it necessitates identifying optimal locations that minimize blind spots while maximizing the sensor’s coverage area. Therefore, to solve this problem, a method for posi

Abstract:

The application of flexible pressure sensor is a new type of pressure sensor based on new materials prepared by a nano process. It differs from conventional pressure sensors due to its good flexibility, free bending, small thickness, high sensitivity, and ease of mass production, and is particularly suited for measuring soft surface contact stress. It has several potential applications in smart homes, smart medicine, wearable gadgets, and other domains. The microstructure can not only increase the sensor's sensitivity, but it can also recover the sensor's elastic deformation more quickly, so i

Abstract:

This paper addresses the problem of determining the reliability of individual sensors in a multi-sensor robotic system in an unknown environment. The inherent difficulty in this problem is that the decision must be based solely upon the data from the sensors themselves. While some previous research has considered unstructured environments (see Refs. 1 and 2 for examples) little if any consideration has been given to totally unknown environments. This problem has usually been avoided by assuming that the sensors would not provide erroneous data or ignoring sensors when they appeared to provide

As many sensor networks have been deployed in industry monitoring area, the focus on sensor data quality has also increased. Sensor networks provide us with process details which we can utilize to help making decisions on process monitoring.In order to make meaningful decisions, the quality of the data produced by sensors must be validated. As we evaluate the status of a specific sensor, we may also regard the status of the related sensors. If a sensor’s data show some abnormal, but the sensors related to it didn’t, we may have much more confidence to believe that the sensor is malfunction. In

Abstract:

Nitrogen–oxygen sensors are pivotal for NOX emission detection, and they have been designed as key components in vehicles’ exhaust systems. However, severe thermal stress concentrations during thermal cycling in the sensors create knotty structural damage issues, which are inevitable during the frequent start–stop events of the vehicles. Herein, to illustrate the effect of thermal concentration on a sensor’s structure, we simulated the temperature and stress field of a sensor through finite element analysis. The failure modes of the sensor based on the multilayer structure model were analyzed.

Detection of silver is vital, because there is an influx of silver into our environment caused by the increased use of AgNP. Therefore, having a sensor that is able to differentiate between and detect only Ag ions is an important first step to solving the toxicity mystery of AgNPs. Chapter 3 focuses on

Abstract:

Användandet av trådlösa sensorer inom byggindustrin är relativt nytt. Sensible solutions AB har utvecklat en produkt för fuktindikering som kan användas i t.ex. lätta utfackningsväggar.

Den ena är täckt med en fuktabsorberande pappersbit som tar upp fukt ur den omgivande luften medan den andra är öppen mot omgivande luft. Sensorerna avläses med en RFID-läsare som sänder ut signaler tills ett svar erhålls från båda taggarna. Den fuktiga taggen kommer att kräva en större

We present a filter-free color image sensor utilizing a full-color-sorting metalens array. Our demonstration shows the sensor’s ability to create high-quality color images while enhancing pixel-signal levels compared with those of conventional image sensors.

Abstract:

Commercial sensors have generally, due to their own characteristics, some undesirable influences on the measured quantity and its precision. In particular, the dynamic characteristics can be reflected on to the measured quantity and lead to false or delayed interpretation of the underlying physical process. The quality and therefore the cost of the sensor is often tied with the dynamic performance of these instruments. Intelligent sensors are able to adapt to changing environments, calibrate themselves, and predict the pattern of the future signal. This paper presents algorithms to improve the

Abstract:

Sensors were deployed by the research team in interior waste bins at Army installation buildings to collect data on waste generation at the source. The sensors were designed to provide granular data on waste generation that stakeholders can use to make informed decisions about solid waste man-agement. Each sensor costs about $300 to fabricate, but bulk fabrication may bring costs down. Sensors were deployed at dining facilities, offices, and barracks, which typically had higher waste volumes. Dining facilities were deemed to be the most useful application because at the other buildings, waste

Abstract:

Currently, several studies and experiments are being done to create a new generation of ultra-low-power wearable sensors. For instance, our group is currently working towards the development of a high-performance flexible pressure sensor. However, with the creation of new sensors, a need for a standard test method is necessary. Therefore, we opted to create a standardized testbed to evaluate the pressure applied to sensors. A pulse wave is generated when the heart pumps blood causing a change in the volume of the blood vessel. In order to eliminate the need of human subjects when testing press

Abstract:

In this 1-year feasibility study, we tried polymerization of several different monomers, commercial as well as novel, specially designed and synthesized for this project in the presence of the nitrate ion to produce imprinted conductive polymers. Polymers 1 and 2 (shown below) produced a response to nitrate, but one inferior to that produced by a polypyrrole (Ppy)-based sensor (which we demonstrated prior to this study). Thus, we elected to proceed with improving the stability of the Ppy-based sensor. In order to improve stability of the Ppy-based sensor, we created a two-layer design which in

Abstract:

Temperature is one of the most common physical quantities (measurand) to be measured in experimental investigations, monitoring and control of building indoor environment, thermal comfort and building energy performance. The most common temperature sensors are the thermocouples and the resistance temperature detectors (RTDs). These analog sensors are cheap, accurate, durable and easy to replace or to repair. The cable of these sensors can easily be shortened or extended. These sensors have a simple, monotonic and stable correlation between the sensor’s temperature and their resistance/voltage

Abstract:

Reviews the available sensors for monitoring hazardous ground movement. Our review was limited to airborne and spaceborne sensors for access, performance, and productivity considerations. It was observed that certain ground movement is comparatively localized, e.g., earthquake faulting, while other activity may extend for thousands of kilometers, e.g., frost heave. Accordingly, we have considered two operating modes for the sensor-platform system, namely, site-by-site and continuous corridor. To determine the suitability of the candidate sensors for pipeline monitoring, we have assessed the ex

Abstract:

Emissions reduction through exhaust aftertreatment is becoming more common. It is likely to play an important role in meeting new emissions regulations in the future. Currently, the predominate aftertreatment technology for NOX reduction in lean burn natural gas engines appears to be selective catalytic reduction (SCR). In SCR, a reducing agent is injected into the exhaust upstream of a catalyst. Supplying the optimal quantity of reagent is critical to effective application of SCR. If too little reagent is supplied then the NOx reduction efficiency may be too low. If too much reagent is provid
