Design of L-Band Power Amplifier by Using Microstrip-Based GaAs p-HEMT MMG15241H Transistor

The power amplifier which is designed by using BJT (Bipolar Junction Transistor) has a larger power consumption, hence in this research, the FET GaAs p-HEMT MMG15241H is used. The power amplifier designed in this research uses microstrip-based and works at the middle frequency of 1.27 GHz. This research yielded a power amplifier which works at the bandwidth with a range frequency of 1.265 A? Â¢? 1.275 GHz, a gain result of 20.02 dB, and input return loss result of -24.45 dB.
Cartographic Guidelines for Geographically Masking the Locations of Confidential Point Data

This research proposes cartographic guidelines for presenting confidential point data on maps. Such guidelines do not currently exist, but are important for governmental agencies that disseminate personal data to the public because these agencies have to balance between the citizens’ right to know, and preserving a citizen’s right to privacy. In an experiment, participants compared an original point pattern of confidential crime locations with the same point pattern being geographically masked. Ten different masking methods were tested. The objective was to identify appropriate geographic masking methods that preserve both the confidentiality of individual locations, and the essential visual characteristics of the original point pattern. The empirical testing reported here is a novel approach for identifying various map design principles that would be useful for representing confidential point data on a map. The results of this research show that only two of the ten masking methods that were tested yield satisfactory solutions. The two masking methods include aggregating point locations at either (1) the midpoint of the street segment or (2) at the closest street intersection. The cartographic guidelines developed from this research suggest a combination of both masking strategies. Future research should focus on the refinement and further testing of these, and other alternative masking methods.
Coupled cell networks: Hopf bifurcation and interior symmetry

We consider interior symmetric coupled cell networks where a group of permutations of a subset of cells partially preserves the network structure. In this setup, the full analogue of the Equivariant Hopf Theorem for networks with symmetries was obtained by Antoneli, Dias and Paiva (Hopf Bifurcation in Coupled Cell Networks with Interior Symmetries, SIAM J. Appl. Dynam. Sys. (2007) to appear). In this note we present an alternative proof of this result using center manifold reduction.
Distance Effects, Social Class and the Decision to Participate in Higher Education in Ireland. ESRI WP444. December 2012

While a number of international studies have attempted to assess the influence of geographic accessibility on the decision to participate in higher education, this issue has not been addressed in detail in an Irish context. The aim of this paper is to fill this gap and to present a higher education choice model that estimates the impact of travel distance on the decision of school leavers to proceed to higher education in Ireland, while also controlling for a range of individual level characteristics and school related variables. To do so we use data from the 2007 wave of the School Leavers’ Survey. We find that, on average, travel distance is not an important factor in the higher education participation decision, when factors such as student ability are accounted for. However, further analysis shows that travel distance has a significantly negative impact on participation for those from lower social classes and that this impact grows stronger as distance increases. We also find that the distance effects are most pronounced for lower ability students from these social backgrounds. This has important implications for higher education policy in Ireland, especially in relation to equity of access and the design of the maintenance grant system.
Delegating budgets when agents care about autonomy

We consider resource allocation within an organisation and show how delegation bears on moral hazard and adverse selection when agents have a preference for autonomy. Agents may care about autonomy for reasons of job-satisfaction, status or greater reputation when performing well under autonomy. Separating allocations (overall budget and degree of delegation) are characterised depending on the preference for autonomy. As the latter increases, the degree of delegation assigned to productive and unproductive agents converges. If agents' preferences for monetary rewards are weak, the principal will not employ financial transfers. Pooling then arises under a strong preference for autonomy.
A Review on Disease Detection, Pathogen Identification and Population Genetics in Fungi

Based on knowing the fungi how much they are important in causing holistic impacts on human welfare, the present review initiated with reviewing the different disease detection and pathogen identification methods of plant pathogenic fungi and over viewing the population genetics of fungi. Currently, more and more diagnostic laboratories and inspection agencies are using molecular methods for detection and identification of diseases caused by plant pathogenic fungi. Better understanding of fungal-plant interactions, pathogenicity factors, rapid and accurate detection of fungal pathogens to species or strain level are a crucial prerequisite for disease surveillance and development of novel disease control strategies. Molecular technology increases understanding of the biology and population structures of plant pathogens, provides quick and accurate answers to epidemiological questions about plant diseases, and supports disease management decisions. Both domestic and international plant quarantine stations must be facilitated with high throughput, rapid and sensitive methods for detection of quarantine pathogens. The methods of population genetics offer powerful tools to elucidate the life histories of important plant pathogens and address fundamental questions about the biology of these organisms. Increased knowledge of the population biology of pathogens is likely to lead to better management of disease in agricultural ecosystems. Eventhough every pathogen detection methods starting from conventional up-to the most sophisticated real-time PCR, they have their own advantages and drawbacks, but selecting of the most appropriate one based on its multi-dimensional importance is crucial at this time. In Ethiopia, most of the detection methods are based on the conventional one, but these methods are not as effective as molecular detection methods. So developing and utilizing these more effective, time sever and easy assays of fungal disease detection and pathogen identification methods is important.

DEVELOPMENT AND EVALUATION OF A PHASE RELATIONSHIP FOR MSW

Compression is one of the most important mechanical aspects of behaviour of municipal solid waste (MSW) which concerns stability, deformation and structural performance in a landfill. Previous studies have shown that compressible particles play a significant role in MSW compression. Definition of the void ratio in classical soil mechanics theory may no longer be applicable for MSW material since high non-linearity between void ratio changes and vertical stress changes have been identified in compression tests. A new phase relationship for MSW has been developed to include the volume loss of compressible particles and this has been evaluated using one-dimensional compression test data. The comparison between analytical and test results has demonstrated that the MSW phase relationship is capable of analysing the volume losses originated from inter- and intra-void ratio changes, in addition to the total volume loss of the MSW sample under different vertical stresses. Since it can isolate the volumetric chang.
Nonadiabatic Quantum Annealing for One-Dimensional Trasverse-Field Ising Model

We propose a nonadiabatic approach to quantum annealing, in which we repeat quantum annealing in nonadiabatic time scales, and collect the final states of many realizations to find the ground state among them. In this way, we replace the diffculty of long annealing time in adiabatic quantum annealing by another problem of the number of nonsidabatic (short-time) trials. The one-dimensional transverse-field Ising model is used to test this idea, and it is shown that nonadiabatic quantum annealing has the same computational complexity to find the ground state as the conventional adiabatic annealing does. This result implies that the nonadiabatic method may be used to replace adiabatic annealing to avoid the effects of external disturbances, to which the adiabatic method is more prone than the nonadiabatic counterpart.
VIDEO BASED VEHICLE DETECTION USING MORPHOLOGICAL OPERATION AND HOG FEATURE EXTRACTION

Vehicle detection plays an effective and significant role in the area of traffic surveillance system, where efficient traffic management and safety is the main concern. In this paper, the video based vehicle detection method using morphological operations and Histogram of Gradient (HOG) feature is proposed. The ROI region is selected and the pixels inside the selected ROI regions alone were detected. Sobel operator is used for the identification of the edge pixels. The gradient is obtained by finding the common pixels in the detected edge and the ROI regions. Finally, the object detection process is employed using Morphological process and Histogram Of gradient Process. Thus, a success rate of around 83% of accuracy is achieved in vehicle detection using proposed method.
The Banning of anti-microbial growth promoters and farm efficiency effects in Danish pig production

This study with focus on the reaction of producers examines the effect of banning antimicrobial growth promoters on efficiency in the production of weaned and finisher pigs using a multi product shadow profit function. We investigated the effect of the ban over time on the changes in total factor productivity (TFP). Our results suggest that there was no effect of the ban on TFP due to outputs and inputs substitution. The high shadow prices for substituting outputs are associated with better export market prices. These findings may have critical implications for the slaughtering plants with over capacity.
SSR ANALYSIS OF CHROMOSOMES 3 AND 7 OF RICE (ORYZA STAIVA L.) ASSOCIATED WITH GRAIN LENGTH

Grain size and weight determine crop yield in cereals, whereas in rice grain size and shape is major attribute to identify market value and also used for classifying rice genotypes. Rice germplasm collection and knowledge of genetic diversity are required for variety improvement. Molecular markers provide powerful tool for identification of genetic variation and mapping of gene/ QTLs. There are a lot of gene/QTLs were identified by different groups on chromosome 3 and 7 controlling grain length. Clustering based on grain length divided the 48 accessions into two major clusters with some contradiction. Genetic relationships among the 48 rice accessions were determined based on allelic diversity using Power Marker tree, structure analyses and PCA using 51 SSR markers located on chromosome 3 and chromosome 7. Twodimensional PCA scaling and power marker tree analysis showed high-level of differentiation between Basmati and indica rice accessions and divide these rice accessions in two distinct clusters.
CORPORATE GOVERNANCE AND INVESTMENTS

We investigate the impact of corporate governance on physical and R&D investments in a Seemingly Unrelated Regressing (SUR) system. Marginal q’s are estimated using firm fundamental information for physical and R&D investments separately. We find that takeover pressure boosts both physical and R&D investments, public pension funds ownership has a U-shaped relation with physical investment, and greater director ownership is associated with lower physical investment and higher R&D investment. As far as investment distortions are concerned, takeover pressure mitigates the free cash flow problem and exacerbates the debt overhang problem, while public pension funds stockholding and director ownership alleviates the debt overhang for physical investment, and R&D investment, respectively.
Are yellow eels from Lake Balaton able to cope with high pressure encountered during migration to the Sargasso sea? The case of energy metabolism

Eels from Lake Balaton are unique because they do not undergo the silvering process and do not migrate. The question is whether these eels, despite such particularities, retain their ability to cope with migration constraints, usually high pressure. To ascertain this, eels were exposed for 3 days to 10.1 MPa of hydrostatic pressure (HP) and the effects of this on aerobic metabolism were evaluated by measuring oxygen consumption (MO2), Cytochrome Oxydase activity (COX) and energetic nucleotide contents in red and white muscles. The results show that Balaton eels survive HP. However, 3 days under pressure induces an alteration in aerobic metabolism. Moreover, when only muscle fibres are exposed to HP, there is a significant decrease in maximal aerobic capacities (-20%). The results are discussed in terms of the ability of these eels to migrate, bearing in mind that this activity represents a high percentage of maximal aerobic capacity when compared with other populations.
Modeling of gasoline hollow cone spray using OpenFOAM

An accurate prediction of gasoline hollow cone sprays is the basis for understanding combustion process in gasoline direct injection engines. Several modifications were made to OpenFOAM 1.4. 1-dev in order to correctly model gasoline hollow cone sprays. First, the real gasoline properties, such as surface tension, dynamic viscosity, heat of vaporization, etc, were implemented into the liquid library. The detailed description of the implementation can be found at www.tfd. chalmers.se/~hani/kurser/OS_CFD_2009/ChenHuang/OFProject0122.pdf . Second, the Rosin-Rammler distribution [1], see equation 1, was implemented in order to simulate the probability density function (PDF) for droplet diameters. ( ) n D n e D n D f � � � � = δ
Population Demographics of Tridacna noae (Röding, 1798) in New Ireland, Papua New Guinea

ABSTRACT The recent resurrection of a Tridacna maxima sensu Rosewater (1965) ecotype as a distinct species, Tridacna noae (Röding, 1798), has raised concerns that inadvertent confusion of the two species in the past may have led to overestimates of T.maxima densities and errors in determining demographic parameters. To assess the potential impacts of such a scenario, this study examined the population demographics of T. noae within the center of its geographic distribution in the Kavieng lagoonal system of New Ireland Province, Papua New Guinea. The study found that 42% of the T. maxima sensu Rosewater population could be delineated as T. noae, with T. noae being the most abundant giant clam species at 7 of the 20 study sites. Past confusion of the two species is likely to be of the greatest concern on reef sites with high or medium levels of exposure to oceanic influences where T. maxima (2.08 ± 0.41 per 400 m2, 1.86 ± 0.59 per 400 m2, respectively) and T. noae (2.06 ± 0.36 per 400 m2, 1.25 ± 0.28 per 400 m2, respectively) densities were similar (P > 0.05). In analyzing size (shell length) frequency distributions, it was determined that the T. noae population had a larger mean size (206 ± 6 mm) than that of T. maxima (161 ±6 mm, P < 0.001). Thus, in areas where the two species have overlapping distributions and fisheries regulations are based on size, reassessment of T. maxima stocks should be considered a priority given the high frequency at which the larger T. noae may comprise historical populations of T. maxima sensu Rosewater.
Interspecies variation in DNA damage induced by pollution

The choice of a suitable species to translate pollution signals into a quantitative monitor is a fundamental step in bio- monitoring plans. Here we present the results of three years of biomonitoring at a new coal power plant in central Italy using three different aquatic and terrestrial wildlife species in order to compare their reliability as sentinel organisms for genotoxicity. The comet assay was applied to the common land snail Helix spp. , the lagoon fish Aphanius fasciatus, and the green frog Rana esculenta sampled in the area potentially exposed to the impact of the power station. The tissue concentration of some expected pollutants (As, Cd, Ni, Pb, Cr) was analysed in parallel samples collected in the same sampling sites. The three species showed different values in the comet assay (Tail Intensity) and different accumulation profiles of heavy metals. Aphanius fasciatus showed an increasing genotoxic effect over time that paralleled the temporal increase of the heavy metals, especially arsenic, and the highest correlation between heavy metals and DNA damage. Helix spp. showed levels of damage inversely related to the dis- tance from the source of pollution and in partial accordance with the total accumulation of trace elements. On the contrary, Rana esculenta showed a low capability to accumulate metals and had inconsistent results in the comet test. The fish appeared to be the most efficient and sensitive species in detecting chemical pollution. Overall, both the fish and the snail reflected a trend of in- creasing pollution in the area surrounding the power plant across time and space (Current Zoology 60 (2): 308-321, 2014).
Chapter 1 Organic Reactions Promoted by Metal-Free Organic Dyes Under Visible Light Irradiation

Although dyes have received much attention as the visible light-activated photocatalysts, the use of metal-free organic dyes in synthetic organic chemistry is still limited. This chapter summarizes the recent progress in the visible light photocatalysis promoted by metalfree organic dyes. Eosin Y is the typical organic dyes to induce the photoredox catalysis. Recently, other organic dyes such as Rose Bengal, fluorescein, and methylene blue have been studied as photocatalysts to promote the single-electron transfer processes.
The Effect of Photovoltaic Panels on the Rooftop Temperature in the EnergyPlus Simulation Environment

In this paper, the effects that photovoltaic (PV) panels have on the rooftop temperature in the EnergyPlus simulation environment were investigated for the following cases: with and without PV panels, with and without exposure to sunlight, and using roof materials with different thermal conductivities and for different climatic zones. The results demonstrate that heat transfer by convection, radiation, and conduction in the air gaps between PV panels and the building envelope can be simulated in the EnergyPlus environment when these air gaps are in the “air conditioning zone. ” Nevertheless, in most cases, particularly on the rooftop, the air gaps between the PV panels and the building envelope cannot be set as the “air conditioning zone. ” Therefore, in this case, none of the EnergyPlus models are appropriate to simulate the effect that PV panels have on the rooftop temperature. However, all the terms of the Heat Balance Model, including the absorbed direct and diffuse solar radiation, net long-wave radiation with the air and surroundings, convective exchange with the outside air, and conduction flux in or out of the surface, can still be used to calculate the temperature and heat flux within the BIPV’s air gap.
Peer Functioning in Children with AD/HD: A Review of Current Understanding and Intervention Options

Research has consistently documented children with attention deficit/hyperactivity disorder (AD/HD) have significant problems in peer relations and strongly rejected by their typically developing peers. There is a growing recognition that traditional interventions, such as social skills trainings are no longer sufficient to address the staggering social needs of children with AD/HD. This paper introduces new directions in interventions for children with AD/HD and advocates that multi-component interventions can be highly beneficial to ameliorate the social problems of children with the disorder. Studies examining the peer relations in children with AD/HD are reviewed and available interventions are explored. In addition, problems with the application of various interventions are discussed and suggested practices are presented.
THE ANALYSIS OF TEMPERATURE TRENDS IN VOJVODINA (SERBIA) FROM 1949 TO 2006

The annual and seasonal trends of surface air temperatures were analyzed on the territory of Vojvodina, north Serbia, using observed data from 10 meteorological stations during 1949-2006. Of the 15 analyzed time series statistically significant positive trends were found in only 2 series. In the remaining 13 series were found trends with reduced statistical confidence. In general, the behavior of temperature could be considered rather non-changeable, than changeable. Quasi-changeable temperatures from 1949 to 2006 are surprisingly similar to the last glacial July paleo-temperatures. It seems that Vojvodina is a territory with more stable climate parameters than other regions.
Does exporting increase productivity of Thai firms via linkage spillovers

Several studies using firm-level data could not find significant evidence to support that exporting activities promote productivity growth. However, few studies have considered whether exporting companies can create spillovers to domestic firms. In fact, exporting companies create positive productivity spillovers to their domestic peers (horizontal spillovers), suppliers (backward linkage spillovers) and buyers (forward linkage spillovers). This paper investigates the existence of productivity spillovers via backward, forward and horizontal linkages from exporting firms to other firms, based on Thai firm-level data. In contrast to existing literature on firms’ productivity, which uses a firm-level dataset to conclude that exporting activities make no contribution to productivity growth of firms, the authors find that backward linkages are the most important spillover channel for exporting firms. Also, the current study finds that export destinations are an important factor in supporting linkage spillovers; only exporting to developed countries creates backward linkage spillovers. Moreover, exporting firms gain most spillovers from backward linkages. Finally, the authors show that productivity spillovers from domestic suppliers are more important than outsourcing.
THE UIP AND TIME VARYING RISK PREMIUM: AN APPLICATION TO THE JAMAICAN BOND MARKET

The UIP is one of the essential assumptions of macroeconomic theory, yet the empirical evidence in support of this condition is weak. This paper tests the UIP condition for Jamaica and finds that the persistence in the deviation is significant, particularly since 1996. This is taken as an indication of the presence of a time varying risk premium in the interest differential, in addition to currency risk. The paper shows that this risk premium is associated with the degree of fiscal dominance as measured by the relative asset supply. The policy implication of the results is that in addition to minimizing currency risk, lowering interest rates will require reducing the supply of Government debt.
