Museum environmental monitoring is an important issue for the artifact conservation. Many solutions have been proposed to tackle this problem, but the museum constraints prevent an easy application in several cases, especially if the monitoring has to be performed in museums where an environmental control system has been already installed. This paper describes a simple though powerful solution, which...
This paper describes a cloud based architecture which has been designed for the monitoring of Cultural Heritage buildings. The architecture has been deployed in museums and basements proving its capabilities. The solution is composed of small sensing nodes with volume lower than 8 cm3 and dimensions of 2.5 cm × 1.5 cm which are capable of acquiring temperature and relative humidity for interval in...
A Tire Pressure Monitoring System (TPMS) is a system that monitors the air pressure and temperature in the tires, and reports real-time information to the driver via wireless communication for vehicle safety and efficiency. On the other hand, several privacy issues regarding TPMS have been reported at the same time. Most of the current TPMSs do not support cryptographic modules for security of the...
This paper presents some practical issues and experience acquired in the design and experimental verification of a small-sized solar concentrator producing both electrical and thermal power. The device is a low-concentration photovoltaic/thermal solar system with a 20 suns ($20\times $ ) concentrator factor and is suitable for integration on building roofs. It consists of four small-sized ($1930 \times 250 \times 166$ ...

A unique wide band receiver for radio astronomy has been designed and constructed. Receivers used for radio astronomy consist of two parts, the front end cold electronics and the back end warm electronics. While the cold electronics provides for a low noise amplifier and receiver calibrations, the warm electronics provides analog signal processing that shapes and filters the signals before digitizing...
Water is an important natural resource and is required in our day to day life. The proposed system aims to design a wireless acquisition system which is the basic building block of the water quality monitoring system. This paper explains the work carried out to design the embedded wireless monitoring system that can measure the turbidity and pH of the water remotely. The system is built using the...
Scouring is the major component of levee failures causing floods thus make the scour monitoring very important. There exist some on field mechanisms to monitor the health of the levees but there is still need for a remote, low cost and real time monitoring system. This paper proposes a real time structural monitoring system by presenting a sensor node with embedded electronics which can be deployed...
A 9Gb/s/pin 8Gb GDDR5 DRAM is implemented using a 20nm CMOS process. To cover operation up to 9Gb/s, which is the highest data-rate among implemented GDDR5 DRAMs [1], this work includes an NBTI monitor, a WCK clock receiver with equalizing and duty-cycle correction modes, CML-to-CMOS converters with wide range operation, active resonant loads at the end of WCK lane, and an on-chip de-emphasis circuit...
This research develops a honeybee behavior monitoring system. The proposed system monitors honeybees' daily activities of getting in and coming out their beehive. It provides a new way to observe honeybee behavior and replace the methods of human observation. Specifically, it automatically records environmental parameters near and in the beehive. The information collected by the system is used for...
Wireless body area network (WBAN) is a term used to describe a network of sensor devices connected wirelessly for communication on, in and near the body to obtain physiological data from sensor devices. This paper explain the implementation of WBAN for monitoring body temperature, heart beat rate and oxygen saturation in blood. We develop the sensor reads physiological data to the desktop application,...

The application of a radio frequency ball bearing cage temperature telemeter in a high speed turbocharger is demonstrated. A temperature dependent LC tank circuit is adhered to the bearing cage and wirelessly monitored using an axially displaced stationary receiver coil. The cage sensor is installed in a turbocharger rotor-bearing system and is able to withstand the harsh conditions of being tested...
The Sardinia Radio Telescope is approaching to its official inauguration. Nowadays, the technical staff is accomplishing the last remaining activities to set up and integrate the microwave receivers, the digital processing systems and all the equipment necessary to reach a top level in the international scenario of large radio telescopes. Even if the radio telescope is still along the technical commissioning,...
In this paper we have proposed a model which acts as a weather station and a rain detector and is solely solar powered. The model is designed in such a way that it can be used remotely and the readings are displayed on a user friendly LCD display and are displayed as digital numeric values. The weather station includes a remote station for monitoring the weather powered by a solar panel, and a base...

Wireless Sensor Networks are event based systems that consists of a collection of autonomous sensor nodes that are spatially distributed and cooperatively monitor physical and environmental conditions. When an event has been detected these sensor nodes become active in transmitting the information and the load becomes heavy, increasing the data traffic and this might lead to congestion that results...
In this paper, we briefly describe the wireless sensor network(WSN), and highlight the design of RF antenna with a gain based on nRF905 chip, then complete an intelligent greenhouse monitoring system for agricultural greenhouse temperature based on WSNs. Finally, we confirm the feasibility of the system design through some tests.
Characterization of single event and low dose-rate TID effects in National Semiconductor's DS16F95 Radiation-Hardened RS-485 Transceiver is eported. Onset LET for upsetof less than 5 MeV-cm2/mg was observed, and a dependency on operating condition was established. Samples under ELDRS nvestigation adhered to electrical specification after irradiation to 30 krd(Si) at 10 mrd(Si)/s.
