Wireless sensor network consist of many sensor nodes in which each sensor node collects the data from sensing environment and transmit it to the Ebase station. The most important key in WSN‘s is to find the optimal path to transmit the data. Nature is the best coach and its designs and strengths are enormously massive and eccentric that it gives inspiration to researchers to emulate nature to s...

This work presents and evaluates different approaches of integrated optical sensors based on photonic circuit (PIC) technologies for refractive index sensing. Bottlenecks in the fabrication flow towards an applicable system are discussed that hinder a cost-effective mass-production disposable sensor chips. As device, waveguide coupled micro-ring approach is chosen which manufactured 8” wafer le...

Lettuce production in the winter on the Adriatic coast, especially in a non-heated plastic tunnel, requires longer cultivation and is characterised by lower head mass and yield. In these conditions, the effect of biostimulant Bio-algeen S-90 and fertilizer Megagreen on the production of the traditional winter lettuce cultivar ‘Four Seasons’ was tested. Both treatments showed a positive effect o...

A special sensitive element based on the novel composite material was created. The sensor has a linear calibration and is resistant to aliphatic hydrocarbons, in particular aviation fuel. A low cost and easy-to-implement method for calibrating the sensor was proposed. Temperature dependence of the oxygen mass transfer coefficient kL was measured for aviation fuel TS-1 (Russi...

Microwave-assisted depolymerization of black-liquor lignin in formic acid was studied, concentrating on the yield of liquid fractions as bio-oil 1 (mainly aromatic monomers) and bio-oil 2 (mainly aromatic oligomers) and the distribution of the specific compositions. Bio-oil 1 (9.69%) and bio-oil 2 (54.39%) achieved their maximum yields under 160 °C with the reaction time of 30 min. The chemical...

We present a label-free (bio)chemical analysis platform that uses all-electrical silicon nanowire sensor arrays integratedwith a small volumemicrofluidic flow-cell for real-time (bio)chemical analysis and detection. The integrated sensing platform contains an automated multi-sample injection system that eliminates erroneous sensor responses from sample switching due to flow rate fluctuations an...

In this paper, we propose a compliant motion control strategy for handling a single object by two similar industrial robots. The dynamics of the object carried by the two robots is assimilated to the dynamics of a mass-spring-damper system described by a piecewise linear model (PWA). The coordination of the two robots is accomplished using a master slave synchronization approach dedicated for P...

The frequency equation of carbon-nanotube-based cantilever sensor with an attached mass is derived analytically using nonlocal elasticity theory. According to the equation, the relationship between the frequency shift of the sensor and the attached mass can be obtained. When the nonlocal effect is not taken into account, the variation of frequency shift with the attached mass on the sensor is c...

The ability to telemetrically measure strain is important in many aspects of daily life which brings important scientific and technological challenges in many sectors such as civil engineering, aircraft modeling, etc..,. Another unrealized, application area is human medicine and healthcare. MEMS (Micro ElectroMechanical System) technology for Radio Frequency applications has emerged in recent y...
