Environmental Studies with the Sensor Web: Principles and Practice

open access: yesSensors, 2005
In 1997, the Sensor Web was conceived at the NASA/Jet Propulsion Laboratory (JPL)to take advantage of the increasingly inexpensive, yet sophisticated, mass consumer-marketchips for the computer and telecommunication industries and use them to create ...

Design of Link-Quality-prediction-based Software-Defined Wireless Sensor Networks [PDF]

open access: yesarXiv, 2021
In wireless multi-hop networks, the instability of the wireless links leads to unstable networking. Even in the newly designed Software-Defined Wireless Sensor Networks (SDWSN), similar problems exist. To further improve the stability of SDWSN, we introduce a Link Quality (LQ) prediction model into the SDWSN architecture.

Measurements and Modelling of Base Station Power Consumption under Real Traffic Loads

open access: yesSensors, 2012
Base stations represent the main contributor to the energy consumption of a mobile cellular network. Since traffic load in mobile networks significantly varies during a working or weekend day, it is important to quantify the influence of these variations

Wireless Expanders

open access: yesProceedings of the 30th on Symposium on Parallelism in Algorithms and Architectures, 2018
This paper introduces an extended notion of expansion suitable for radio networks. A graph $G=(V,E)$ is called an $( _w, _w)$-{wireless expander} if for every subset $S \subseteq V$ s.t. $|S|\leq _w \cdot |V|$, there exists a subset $S'\subseteq S$ s.t.

Plasma lipidomic and metabolomic profiles in high‐grade glioma patients before and after 72‐h presurgery water‐only fasting

open access: yesMolecular Oncology, EarlyView.
Presurgery 72‐h fasting in GB patients leads to adaptations of plasma lipids and polar metabolites. Fasting reduces lysophosphatidylcholines and increases free fatty acids, shifts triglycerides toward long‐chain TGs and increases branched‐chain amino acids, alpha aminobutyric acid, and uric acid.

Wireless and Simultaneous Detections of Multiple Bio-Molecules in a Single Sensor Using Love Wave Biosensor

open access: yesSensors, 2014
A Love wave-based biosensor with a 440 MHz center frequency was developed for the simultaneous detection of two different analytes of Cartilage Oligomeric Matrix Protein (COMP) and rabbit immunoglobulin G (IgG) in a single sensor. The developed biosensor
