Specific binding of the anticoagulants heparin and antithrombin III to the blood clotting cascade factor human thrombin was recorded as a function of time with a Love-wave biosensor array consisting of five sensor elements. Two of the sensor elements were used as references. Three sensor elements were coated with RNA or DNA aptamers for specific binding of human thrombin. The affinity between t...

GSN is an open source middleware designed for managing data produced by sensors deployed in a sensor network. We have extended the GSN to enable (i) semantically aware preparation, exchange and processing of the data (ii) user specified event processing for alerts, and (iii) associate sensor data to things. Here, we demonstrate our smart farm as a use case of a semantically aware sensor network...

Due to the dangerous nature of anthrax, the development of a cost-effective, sensitive and field-portable sensor for the anthrax biomarker--calcium dipicolinate (CaDPA)--is of exceptional significance for both military and civilian use. Herein, a flexible polymer-film-based ratiometric sensor for detecting CaDPA was demonstrated. A reference dye and a probe ligand were covalently immobilized on...

A new europium(III) membrane luminescent sensor based on a new tridentate bis(phosphinic acid)phosphine oxide (3) system has been developed. The synthesis of this new ligand is described and its full characterization by NMR, IR and elemental analyses is provided. The luminescent complex formed between europium(III) chloride and ligand 3 was evaluated in solution, observing that its spectroscopi...

adequate coverage is one of the main problems for distributed wireless sensor networks and the effectiveness of that highly depends on the sensor deployment scheme. given a finite number of sensors, optimizing the sensor deployment will provide sufficient sensor coverage and save power of sensors for movement to target location to adequate coverage. in this paper, we apply fuzzy logic system to...

Animal venoms contain a fascinating array of divergent peptide toxins that have cross-activities on different types of voltage-gated ion channels. However, the underlying mechanism remains poorly understood. Jingzhaotoxin-III (JZTX-III), a 36-residue peptide from the tarantula Chilobrachys jingzhao, is specific for Nav1.5 and Kv2.1 channels over the majority of other ion channel subtypes. JZTX-...

A Wireless Sensor Network (WSN) consists of distributed an autonomous devices that monitors both physical and environmental conditions. Sensor Networks are used for weather prediction and measuring temperature, sound, wave, vibration, pressure etc. Sensor Networks suffer from various security attacks like (i) sink hole attack, (ii) black hole attack, (iii) wormhole attack and (iv) selective for...

This contribution presents Soft Computing Robot Navigation for mobile robot SCORCAS, a Case Study. The Navigation uses fuzzy logic experienced on mobile robot systems. Fuzzy logic is applied in analogous way into three sub-systems: i. Sensor, consisting of five autonomous sensor sub-systems: visual, acoustic, tactile, thermal and inertial; ii. Sensor fusion that comprise all the robot stimulus ...
