Internet of things (IoT), also referred to as the internet of objects, is a dynamic global information network consisting of internet — connected objects. Wireless sensor networks (WSN) and RFID enabled Internet of Things finds a plethora of applications in almost all the fields such as education, health, agriculture, transportation and entertainment. Compact smart devices constitute an essential...
Palladium and palladium alloys (nickel, cobalt and nickel co-substituted) were prepared using low temperature chemical reduction technique at 300 K. The synthesized metal and alloys were deposited using PLD on alumina substrate. The deposited nanostructured thin film alloys showed much better sensitivity towards hydrogen between the concentrations of 2000 and 20000 ppm of hydrogen than pure palladium...
Compositions of nominal formula, SrFe1−xTixO3-δ (x = 0 − 0.8) were prepared by solid state method and characterized by X-ray diffraction and Mossbauer spectroscopic studies. Electrical conductivities of these samples were studied at different temperatures in three different oxygen concentrations. Thin films of SrFe0.2Ti0.8O3-δ and SrFe0.35Ti0.65O3-δ were deposited on polycrystalline alumina using...

This paper investigates indium antimonide based quantum well field effect transistors with 40 nm physical gate length. Self consistent T-CAD simulations are used to study the high-speed potential of InSb field-effect transistors and its suitable for high speed, very low power logic applications. At the room temperature electron mobility in excess of 30,000 cm2/V−1s−1 in material with sheet carrier...
In this paper a new flip flop in the clock distribution network is introduced. Normally in the clock distribution networks a sinusoidal signal is given at the clock port. Here we are using the low swing DCCF by using reduced swing inverters. This flip flop output has to be checked at the two corners by using simulations that has to be extracted from the layout. The LS-DCCF has to be simulated by using...
Grid Computing emerged as a wide scale distributed system to offer dynamic coordinated resources sharing and high performance computing. Grid coordinates the resources that are not subject to centralized control. It uses standard open, general purpose protocols and its interfaces. Grid delivers non-trivial qualities of service such as the response time, throughput, availability and security. Grid...
Distributed Denial of Service (DDoS) attacks is measured to be a vital threat to the net. Because of memory less feature of the net routing mechanism, it's extraordinarily onerous to trace back to the supply of those attacks. Ancient packet marking techniques are not any longer applied because of its high memory consumption and poor measurability. During this paper, we have a tendency to build use...
The performance of 25nm Symmetric Extended Source/Drain Schottky Tunneling Transistor (ESD-ST-SOIFET) with different gate structures are investigated through a TCAD modeling study. It is shown that, the doped extension regions adjacent to the source/drain schottky barrier improves the drive current by shrinking the schottky barrier and also the simulation results shows that the increasing doping levels...
The Asymmetric Schottky Tunneling Source SOI-MOSFET (STSFET) is a promising device alternative for future nanometer-scale technology. The device has been modeled and simulated using TCAD SYNOPSYS tool. This paper presents a detailed study of device structure, design and characteristics of both p-type and n-type Asymmetric Schottky Tunneling Source SOI-MOSFETs. The important parameters of the device...
Oxygen Concentration Monitoring is an important requirement in fighter aircrafts. This paper reports the results of performance evaluation of an indigenous Zirconia Oxygen Sensor, which meets the requirements of a fighter aircraft environment. The Oxygen Sensor uses a solid state electrolyte, Zirconia stabilized with 8mol% Yttria, in the form of a Nernst Cell, which when heated above 600°C, develops...
An ammonia sensor based on Ag6Mo10O33 thick film was fabricated and tested. The morphology of the film was characterized by SEM. The electrical capacitance and impedance of the compound were investigated by exposing the film in air, air containing 500 vppm of H2, petroleum gas (PG) and NH3 independently at 350°C using AC impedance spectroscopy. When the film was exposed to air containing ammonia significant...
Nominal compositions of general formula In2−xMnxO3−δ were prepared by solid-state route and their electrical conductivity and hydrogen sensing characteristics were investigated. With manganese addition, the conductivity was found to increase initially and then decrease while the activation energy for the conduction process was increasing. In1.99Mn0.01O3-δ, In1.985Mn0.015O3-δ, In1.98Mn0.02O3-δ were...
In2O3 thin film was fabricated using pulsed laser deposition technique. The structure and morphology of the thin film were characterized by X-ray diffraction and atomic force microscopy respectively. AC impedance of In2O3 thin film gas sensor were investigated at different temperatures (275 – 425 °C) when exposed into clean air and air containing NOx. Significant NOx sensing characteristics of thin...
Turbo decoder uses any one of the decoding algorithm, Maximum A posteriori Probability (MAP), or Soft Output Viterbi Algorithm (SOVA) because it produces error correction near to Shannon's limit. The Log MAP is a Soft Input Soft Output (SISO) algorithm, which determines the log likelihood of each transmitted data bit. A simple but effective technique to improve the performance of Log MAP algorithm...
In a Sodium Fast Reactor (SFR), due to the necessity to reduce the probability of occurrence of water ingress in the Steam Generator Unit (SGU), the availability of a reliable detection system is essential. Several concepts are available: a diffusion nickel membrane with a mass spectrometer is worthwile set-up on reactors. Nevertheless, it requires a periodical calibration and an important maintenance...
Turbo decoder uses any one of the decoding algorithm of maximum a-posteriori probability algorithm (MAP) or soft output viterbi algorithm (SOVA).SOVA provides an efficient way to find the most likely sequence of state transitions of a finite state chain. SOVA determine the most likely sequence to have been transmitted instead of determining most likelihood for each data bit. The traditional turbo...
Turbo decoder uses any one of the decoding algorithm of maximum a-posteriori probability algorithm (MAP) or Soft Output Viterbi Algorithm (SOVA). The traditional turbo code system use equal error protection (EEP). In many applications all the information don't need equal importance. So we need a new method unequal error protection (UEP). By doing so the important message is more protected than the...
