In recent years, irrigations have been built on dry areas in Majes-Arequipa. Over time, the irrigations water forms moist areas in lower areas, which can have positive or negative consequences. Therefore, it is important to know in advance where the water from the new irrigation will appear. The limited availability of real-time satellite image dat...

Bending, twisting or vibrations in coaxial and multi-wire cables can generate signal noise, often dominated by triboelectric charging effects. Cables that ensure low triboelectric noise are called low noise cables. These cables are used in many low-level measurement applications such as medical instruments and sensors in nuclear plant. In this work...

In many countries around the world, most of the waste use to be disposed of to landfills, this generate public concern about the health effects of emissions. Landfill gases are produced by the natural bacterial decomposition of waste and it is about half of methane, with the remainder mostly carbon dioxide and minor amounts of other gases. Real-tim...

Monitoring urine ketones can be useful for diagnosing diabetes. In this paper we present a method to detect diabetic ketoacidosis in synthetic urine samples by sniffing dimethyl ketone traces. A portable E-nose was developed using five metal oxide (MOX) gas sensors configured and controlled by eight bits microcontroller. The analog signals from gas...

... Another paper [2], shows a developed prototype which allows visualizations of meteorological picture reception systems using SDR and GNU radio. After going through the research paper, the main motive behind designing the proposed system and obtaining the results with a self-designed antenna was clear. ...
... Several interesting applications of drone-borne instrumentation for methane emission monitoring have been proposed recently (Table 9). For example, in Montoya et al. [144], the authors deployed a drone-based set-up equipped with low-cost MOS sensors for detection of CH 4 , CO, and CO 2 . The authors have carried out laboratory and field measurements with promising results for further development. ...
... Many of these metabolites have also been associated with lung damage caused by different etiologies like cystic fibrosis, COPD, asthma and lung cancer [40,47,48]. These studies indicate that VOC patterns may indeed be used in disease progression monitoring, this has been proven in liver diseases, diabetes, and asthma [49][50][51]. Thus, based on our results this technique could more ubiquitously be used to evaluate post-COVID patients and determine their progression vs. the chemical VOC fingerprint phenotype of healthy controls. ...
... To address the problem of outdoor parking difficulties, Postigo-Málaga et al. investigated a parking space location method based on RSS fingerprints of parking spaces. By collecting the signal strength of parking spaces during idle and busy hours, a fingerprint database was constructed, and then, the parking spaces were located by fingerprint matching [8]. ...
... A range of gasses can detect through the MQ series that are used indoors at room temperature. MQ is a semi-metal gas sensor by Metal Oxide Semiconductor (MOS) that known as Chemiresistors since the gas detection depends on changing the resistance of the sensor material when the gas encounters the material [3]. It can detect gas concentrations through a simple voltage divider, where the result is an analog output signal and able to read with an analog input of the Micro-controller [4]. ...
