ALL OPTICAL SIGNAL REGENERATION TECHNIQUE DESIGN AND REAL TIME IMPLEMENTATION FOR DIFFERENT MODULATION SCHEMES USING ULTRASCALE FPGA BHAGWAN DAS UNIVERSITI TUN HUSSEIN ONN MALAYSIA ALL OPTICAL SIGNAL REGENERATION TECHNIQUE DESIGN AND REAL TIME IMPLEMENTATION FOR DIFFERENT MODULATION SCHEMES USING UL

The all-optical signal regeneration is a demanding research area for long haul optical communication systems. Electronic signal regeneration is limited due to its real-time infeasibility in terms of data rate and accumulated losses; therefore, all-optical signal regeneration is utilized to overcome these issues. The existing all-optical signal regeneration techniques have not been able to facilitate low power consumption, demonstration of real-time low cost commercial based design systems and application for the optical systems. In this research, a new all-optical signal regeneration technique is developed using singlepump Phase Sensitive Amplification, designed Optical Frequency Locked Model and noise mitigation model. The designed technique consumes less power than existing signal regeneration techniques for 10Gb/s optical degraded signal for different amplitude and phase modulation formats transmitted at different transmission distances between 50 km to 250 km. The designed all-optical signal regeneration technique is realized using numerically and verified using Simulink model. A real-time demonstration and commercial design based application is developed using Xilinx KCU105 UltraScale FPGA. The new all-optical signal regeneration technique has achieved a very low Bit Error Rate (BER) of 10 at low received power of -16 dBm averagely for different transmission distances between 50 km to 250 km via simulation and experiment. The new all-optical signal regeneration technique consumes low power of -16dBm, compared to existing all-optical signal regeneration techniques that consumes -9dBm. The new all-optical signal regeneration technique consumes 45% less power; with low BER and low received power compared to existing technique. The new all-optical signal regeneration system offers, real time implementation, live monitoring and commercial based design for Differential Phase Shift keying (DPSK) Non-Return-to-Zero (NRZ), DPSK-Return-to-Zero (RZ), Binary PSK (BPSK), Differential BPSK, Quadrature PSK, Orthogonal Frequency Division Multiplexing (OFDM), Quadrature Amplitude Modulation (QAM), Binary Frequency Shift Keying (BFSK), 8-PSK, and On-Off Keying (OOK).

Salmonella was isolated from 3%(2/66) of swine rectal swab samples and 96%(24/25) of pork samples. In rectal swab samples, both S. Weltevreden and S. Dumfries were isolated from one sample, and S. Stanley from another sample. In pork, a total of 42 isolates (16 serovars) were found ; 8 strains of S. Rissen, 5 strains of S. Stanley and S. Anatum, 4 strains of S. Give and S. Kedougou, 3 strains of S. Welteverden, 2 strains of S. Hvittingfoss, S. Agona and S. Krefeld, and only 1 strain of 7 serovars were isolated. The resistance of Salmonella isolates was highest for tetracycline (69%), followed by ampicillin (50%), sulfamethoxazoletrimethoprim (36%), streptomycin (31%), chloramphenicol (14%), cefotaxime (5%), and ciprofloxacin (2%). S. Stanley and S. Weltevreden were found in both rectal swab and pork samples; however, pulsed-field gel electrophoresis and resistance profiles revealed no relationship between the rectal swab and pork isolates. In our study, Salmonella was isolated from only 3% of swine rectal swab samples, however, pork at a meat retailer in Sa Kaew province had a high prevalence of Salmonella. The result suggested that cross contamination may occur during slaughter house, transportation, to retail shop. Keywords : antimicrobial susceptibility, PFGE, pork, Salmonella spp. , swine
Near Net Shape Fabrication Of Pmn Scaffolds

Solid free form fabrication techniques are commonly employed in near net shaping of ceramics especially in the manufacture of microelectronics. Lead magnesium niobate (PMN) is an important relaxor ferroelectric material with perovksite structure used in the production of these multilayer ceramic devices. In this study two dimensional PMN arrays and three dimensional periodic structures were produced by robocasting which is a direct writing technique. Aqueous colloidal gels have been formulated for use as ink in solid freeform fabrication process. Results showed that complex PMN shapes having rod size down to 100 μm can be successfully produced by robocasting process to be used in microelectronic applications.
Assessing the ecological coherence of a marine protected area network in the Celtic Seas

Marine protected areas (MPAs) are a management tool used to respond to human-derived threats in marine ecosystems. Historically, MPAs have been established on an individual ad hoc basis, rather than through a systematic, planned process. However, high levels of functional and spatial connectivity within marine ecosystems have led to the suggestion that networks of MPAs provide greater ecological benefits than individual MPAs. Consequently, international policy has developed to consider broader spatial requirements for marine conservation, resulting in a number of international and regional agreements that require the establishment of ecologically coherent MPA networks. Existing MPAs are now being considered, retrospectively, alongside new designations, as networks of MPAs across regions, both nationally and internationally. Under the Marine Strategy Framework Directive (MSFD), France, the Republic of Ireland, and the UK (including Northern Ireland and the Isle of Man) are required to work together to ensure coordinated development of marine strategies for the Celtic Seas subregion. Accordingly, MPAs have been identified as crucial components of the programme of measures to achieve Good Environmental Status (GES) under the MSFD. Here, we provide the first ecological coherence assessment of an MPA network spanning an MSFD subregion. A network of 533 MPAs, or parts thereof, across the Celtic Seas subregion was assessed using five criteria and two methodologies, with a focus on broadscale habitats. While the Celtic Seas MPA network as a whole is not ecologically coherent (according to accepted thresholds), progress toward a number of global targets has been achieved, for example, protection of 10% of marine and coastal areas under the Convention on Biological Diversity. Further, all MSFD predominant habitat types assessed are adequately represented and replicated within the network. However, a number of gaps were identified, including a lack of MPAs in offshore and deeper areas, and inadequate proportions of predominant habitat types within MPAs. Addressing these gaps to enable the MPA network to fulfill its critical role in the delivery of GES under the MSFD will require both national progress toward designation of adequate and viable MPAs and transboundary agreements and coordination of MPA designation processes at the European level.
Human Motion Reconstruction using Wearable Accelerometers

We address the problem of capturing human motion in scenarios where the use of a traditional optical motion capture system is impractical. Such scenarios are relatively commonplace, such as in large spaces, outdoors or at competitive sporting events, where the limitations of such systems are apparent: the small physical area where motion capture can be done and the lack of robustness to lighting changes and occlusions. In this paper, we advocate the use of body-worn wearable wireless accelerometers for reconstructing human motion and to this end we outline a system that is more portable than traditional optical motion capture systems, whilst producing naturalistic motion. Additionally, if information on the person's root position is available, an extended version of our algorithm can use this information to correct positional drift.
Analyzing Demand For Disposal And Recycling Services: A Systems Approach

Pricing municipal solid waste (MSW) services using a flat fee offers no incentive to conserve on disposal. This has prompted the use of unit pricing schemes, which should reduce disposal in accordance with demand theory and encourage alternatives such as recycling. Most studies estimate distinct demand equations for disposal and recycling, and none use a systems approach to simultaneous estimate them. To that end, this research estimates such a model, which also recognizes the endogeneity of policy variables. The results offer important policy insight and shed light on the effectiveness of unit pricing in reducing disposal and simultaneously encouraging recycling.
Influence of Annealing Temperature on the Magnetic Properties of Rapidly Quenched (Nd,Pr)2-(Fe,Co,Ga,Ti,C)14B/α-Fe Nanocomposite Ribbons

The effects of different heat treatment temperatures on the structure and magnetic properties of Nd-Fe-B nanocomposite permanent magnetic alloys with nominal composition of Nd9.4Pr0. 6Fe74.5Co6B6Ga0. 5Ti1.5C1. 5 have been investigated. The most practical method to produce nanostructured metallic materials is rapid solidification. Melt spinning with constant wheel speed of m/s was employed to produce ribbons. As-spun ribbons were examined by using differential scanning calorimetry (DSC) and X-ray diffractometer (XRD) with Cu-kα radiation. The ribbons were annealed at different temperatures in order to extract the best magnetic properties. The XRD and electron microscopy technique results confirm that grains are in the size of less than 50 nm. In addition, optimum magnetic properties were obtained at 700°C annealed temperature.
Assessing the Invasion Risk of Eucalyptus in the United States Using the Australian Weed Risk Assessment

Many agricultural species have undergone selection for traits that are consistent with those that increase the probability that a species will become invasive. However, the risk of invasion may be accurately predicted for the majority of plant species tested using the Australian Weed Risk Assessment (WRA). This system has been tested in multiple climates and geographies and, on average, correctly identifies 90% of the major plant invaders as having high invasion risk, and 70% of the noninvaders as having low risk. We used this tool to evaluate the invasion risk of 38 Eucalyptus taxa currently being tested and cultivated in the USA for pulp, biofuel, and other purposes. We predict 15 taxa to have low risk of invasion, 14 taxa to have high risk, and 9 taxa to require further information. In addition to a history of naturalization and invasiveness elsewhere, the traits that significantly contribute to a high invasion risk conclusion include having prolific seed production and a short generation time. Selection against these traits should reduce the probability that eucalypts cultivated in the USA will become invasive threats to natural areas and agricultural systems.
SOFIA observations of far-infrared hydroxyl emission toward classical ultracompact HII/OH maser regions

Context. The hydroxyl radical (OH) is found in various environments within the interstellar medium (ISM) of the Milky Way and external galaxies, mostly either in diffuse interstellar clouds or in the warm, dense environments of newly formed low-mass and highmass stars, i.e, in the dense shells of compact and ultracompact HII regions (UCHIIRs). Until today, most studies of interstellar OH involved the molecule’s radio wavelength hyperfine structu re (hfs) transitions. These lines are generally not in local thermodynamical equilibrium (LTE) and either masing or over-cooling complicates their interpretation. In the past, observations of tr ansitions between different rotational levels of OH, which are at far-infrared wavelengths, have suffered from limited spectral and angular resolution. Since these lines have critical densities many orders of magnitude higher than the radio wavelength ground state hfs lines and are emitted from levels with more than 100 K above the ground state, when observed in emission, they probe very dense and warm material. Aims. We aim to probe the warm and dense molecular material surrounding the UCHIIR/OH maser sources W3(OH), G10.62−0.39 and NGC 7538 IRS1 by studying the 2 �1/2, J = 3/2− 1/2 rotational transition of OH in emission and, toward the last source also the molecule’s 2 �3/2, J = 5/2− 3/2 ground-state transition in absorption. Methods. We used the Stratospheric Observatory for Infrared Astronomy (SOFIA) to observe these OH lines, which are near 1.84 THz (163 µm) and 2.51 THz (119.3 µm), with high angular (∼16”/11”) and spectral resolution (better than 1 km s −1 ). Results. We clearly detect the OH lines, some of which are blended with each other. Employing non-LTE radiative transfer calculations we predict line intensities using models of a low OH abundance envelope versus a compact, high-abundance source corresponding to the origin of the radio OH lines. From the observed velocities and line-widths we can place constraints on the origi n of the emission, and with detailed modeling we show for instance that the OH emission of W3(OH) comes from the UCHIIR and not from the envelope of the nearby hot-core. Conclusions. The far-IR lines of the OH molecule provide important information on the density and temperature structure of UCHIIRs. Taking a low-abundance envelope component is not suffi cient to reproduce the spectra for W3(OH) and G10.62−0.39, a compact, high OH column density source ‐ corresponding to the OH radio emitting sources is definitively required.
Early diagnosis and monitoring of nitrogen nutrition stress in tomato leaves using electrical impedance spectroscopy

Abstract: Nitrogen (N) is a life element for crop growth. In tomato growth and development, N stress often occurs and degrades crop yield and quality. Superfluous N can noticeably increase the nitrate content, which can be degraded into strong carcinogenic substance- nitrite. An accurate and timely monitoring and diagnosis of nutrition during crop growth is premise to realize a precise nutrient management. Crop N monitoring methods have been developed to improve N fertilizer management, and most of them are based on leaf or canopy optical property measurements. Although many optical/spectral plant N sensors have already commercialized for production use, low accuracy for phosphorus (P) and potassium (K) detection and diagnosis remains an important drawback of these methods. To explore the potential of N diagnosis by electrical impedance and perform study for nutrition status of plant NPK meanwhile by the electrical impedance, it is necessary that evaluate the N nutrition level by leaf impedance spectroscopy. Electrical impedance was applied to determine the physiological and nutritional status of plant tissues, but few studies related to plant N contents have been reported. The objective of this study was to evaluate the N nutrition level by leaf impedance spectroscopy and realize the early diagnosis and monitoring of N nutrition stress in tomato. Five sets of tomato plant samples with different N contents were cultivated in a Venlo greenhouse. N content of leaves was determined, and electrical impedance data were recorded in a frequency range of 1 Hz to 1 MHz. The obtained impedance data were analyzed using an equivalent circuit model for cellular tissues. The variation of equivalent parameters along with N content was analyzed, and the sensitive impedance spectroscopy characteristics of N nutrition level were extracted. Furthermore, the effect of moisture content on impedance measurement was discussed and the prediction model for N content was developed. Results showed that electrical impedance can be conveniently applied to early diagnosis and monitoring for tomato N nutrition stress.

Electrochemical Performances of Li+ Intercalation and Deintercalation Processes for Electrochromism of MoO3-Doped V2o5 Films Prepared By The Sol-Gel Method

The MoO3-doped V2O5 thin films electrode exhibit much enhanced electrochemical performances than the pure V2O5 counterpart. 1M nonaqueous solution of LiClO4 in propylene carbonate (PC) was the electrolyte solution about cyclic voltammetry (CV) of V2O5/MoO3/ITO glass electrodes at room temperature. With the increasing proportion of MoO3 doped in V2O5, all the redox peak currents of the five samples increased, suggesting that their electrochemical activity increased with the initial CV cycles. Disappearing of some phase transition peaks also show that the MoO3-doped V2O5 film makes cyclic stability declining. Compared with the switching speed of films, the coloring and the bleaching times of the MoO3-doped V2O5 thin films are shorter.
Comparative Analysis of Internet of Things (IoT) based Low Power Wireless Technologies

— Internet of Things (IoT) marketplace is swiftly expanding as companies across multiple vertical industries recognize the need for connectivity and the potential transformation enabled through connectivity. In short, the Internet of Things refers to the rapidly growing network of connected objects that are able to collect and exchange data using embedded sensors. NB-IOT (Narrowband - Internet of Things), LoRa, and Sigfox wireless technologies have been getting a good deal of attention globally as the market for wireless matures in light of the prospects for billions of connections. The goal of the LoRa Alliance, LoRaWAN adopters, and SigFox is that mobile network operators adopt their technology for IoT deployments over both city and nationwide low power, wide-area networks (LPWANs). But there are some prominent differences between how each technology plans to achieve this goal and which applications the technology is best suited for.
Between privatization and intermunicipal cooperation: small municipalities, scale economics and transantion costs

espanolEn este articulo, se analiza el uso que los municipios pequenos pueden hacer de la cooperacion intermunicipal para producir de forma eficiente servicios locales. La principal hipotesis que se analiza es que los pequenos municipios pueden utilizar la cooperacion intermunicipal como alternativa a la privatizacion para explotar economias de escala. En este sentido, la cooperacion intermunicipal puede implicar menores costes de transaccion que la privatizacion. Con el proposito de contrastar esta hipotesis, se revisan en primer lugar las teorias que ofrecen perspectivas utiles respecto a las ventajas de costes de las diferentes formas de produccion. A continuacion, se analiza la informacion que proporciona una base rica de datos respecto al servicio de recogida de basuras y el suministro de agua en Espana, los cuales constituyen los servicios locales mas comunmente estudiados por su relevancia economica. De este analisis, puede concluirse que la cooperacion es mas frecuente cuando el servicio es producido por el sector publico, mientras que la produccion privada es mas frecuente cuando el servicio es suministrado a nivel municipal. Ademas, se muestra evidencia de que los costes de produccion son menores cuando tiene lugar la cooperacion intermunicipal. EnglishIn this paper, we analyze the use of intermunicipal cooperation as a possible mechanism for small municipalities to deliver efficiently local services. The main hypothesis to be analyzed is that small municipalities may use intermunicipal cooperation to exploit scale economies as an alternative to privatization. In this way, lower transaction costs might be a cost advantage that intermunicipal cooperation provides in relation to privatization. In order to test our hypothesis, we first review theories that provide useful insights on cost advantages of different production forms. Then, we analyze extensive data for Spain concerning solid waste collection and water distribution services, which are the local services more commonly studied for their major economic relevance. From such data analysis, we conclude that cooperation is more frequent when production is public, while private production is more frequent when the service is provided by the municipality. Additionally, we show that production costs are lower when intermunicipal cooperation takes place.
A Grid-Connected Multilevel Current Source Inverter and Its Protection for Grid-Disconnection

Traditionally DC-AC converters are considered with voltage source inverters (VSI); although less studied and discussed, it has started recently to be used current source inverters (CSI). Another possibility for DC/AC conversion is the multilevel configuration. This paper shows experimental operation and simulation analysis of a grid-connected multilevel current source inverter (MCSI), which includes a circuit for equipment safety reasons due to grid disconnections.
Recent Results from the NIST Pulse-Heated Kolsky Bar

A Kolsky bar laboratory for measuring dynamic material properties, in support of improved finite-element modeling of high-speed machining processes, has been developed at the National Institute of Standards and Technology (NIST). The NIST split-Hopkinson pressure bar has the capability of electrically pulse heating a test sample to a temperature on the order of 1000 oC in less than a second, then holding the sample at a fixed high temperature for several seconds (if desired), followed by loading of the sample in a dynamic compression test. Recent advances in temperature measurement and control capabilities are discussed, together with recent results on the constitutive response of AISI 1045 steel. The goal of the work is to study the influence of the rate of heating and time at high temperature on the stress-strain response of the material, which depends upon the dynamic evolution of the material’s microstructure.
