Wireless sensor networks equipped with various gas sensors have been actively used for air quality monitoring. Previous studies have typically explored system issues that include middleware or networking performance, but most research has barely considered the details of the hardware and software of the sensor node itself. In this paper, we focus on the design and implementation of a sensor boa...

Two-Level Grammar (TLG) is proposed QS an object-oriented requirements specification language with Q natural language (NL) style but suficiently formal to allow automatic transformation of the TLG specification into formal specifications in VDM++, an object-oriented version of the Vienna Development Method. The VDM++ specification may be further transformed into JavaTM code or integrated with t...

A compact and transportable three channel quantum cascade laser system (TRIPLE Q) based on mid-infrared absorption spectroscopy has been developed for time-resolved plasma diagnostics. The TRIPLE Q spectrometer encompasses three independently controlled quantum cascade lasers (QCLs), which can be used for chemical sensing, particularly for gas phase analysis of plasmas. All three QCLs are opera...

The commercially-available database systems for storing and searching Markush structures from chemical patents have undergone little change since their launch some twenty years ago. However, the past few years have seen the area become an active one again for research and development. This presentation offers an overview and commentary on recent and current activity, and discusses the prospects...

In this paper, deep sub-micron CMOS process compatible high Q on chip spiral inductors with air gap structure were designed and fabricated. In the design the electromagnetic solver, SONNET, and the finite element program, ANSYS, were used for electrical-characteristics and maximum mechanical strength, respectively. The copper wires were capped with electroless Ni plating to prevent the copper f...

The growing applications of nanoparticles in energy and healthcare demand new metrology techniques with improved sensitivity, lower sample concentration, and affordable instrument cost. Here we demonstrate the first air-mode photonic crystal nanobeam cavity with ultrahigh Qfactor (Q = 2.5 × 10) and ultrasmall mode volume (V = 0.01λ) at telecom wavelength. The air-mode cavity has strong field lo...

Synbranchus marmoratus is a facultative air-breathing fish, which uses its buccal cavity as well as its gills for air-breathing. S. marmoratus shows a very pronounced tachycardia when it surfaces to air-breathe. An elevation of heart rate decreases cardiac filling time and therefore may cause a decline in stroke volume (V(S)), but this can be compensated for by an increase in venous tone to mai...

This paper develops a Q-learning approach to Unmanned Air Vehicle (UAV) navigation, or path planning, for sensing applications in which an infrared (IR) sensor or camera is installed onboard the UAV for the purpose of detecting and classifying multiple, stationary ground targets. The problem can be considered as a geometric sensor-path planning problem, because the geometry and position of the ...

Haney-type surface thermal boundary conditions linearly connect net downward surface heat flux Q to air– sea temperature difference (gradient-type condition) DT1 or to climate/synoptic sea temperature difference (restoring-type condition) DT2 by a coupling coefficient k. In this study, the authors used the global reanalyzed data (6-h resolution) of Q, surface air temperature TA, and sea surface...

conclusions cardiovascular and respiratory problems mortality, as well as referrals to hospitals due to such diseases, was increased since 2010 till 2012. in 2013, however, the death toll was less than what had been in 2012, in spite of more concentration. the reason is that ahvaz had 160 days with concentration more than 400 μg/m3 in 2013 whereas this was 198 days in 2012. also, every 10 μg.m-...
