Urban areas extraction from multitemporal SAR RGB images using interferometric coherence and textural information

In this paper, we introduce an innovative methodology for urban areas extraction based on a new class of multitemporal colour composite products. As first, we propose a method for enhancing the coherence characteristic of the image adapting the dimension of the main window to the scene target. Thus, we show how to link this property with a colour attribute, which is combined with textural information to form the final fuzzy urban areas map.
The Effect of Budget Deficit Shock on Government Spending: An Empirical Case in Indonesia

This paper aims to investigate the effect of budget deficit shock on government spending in Indonesia. For this propose, this reasearch uses an alternative error correction model based on loss function of government spending. The model assumes the short run disequilibrium, in which shock variables may play an important role. A spesific loss function model is applied to develop the long run government hypothetical model. Using data of the period 1970-2010, the empirical model shows that real GDP, tax revenue and multi period shock of budget deficit are statistically significant in determining the government spending, both for operating and development spending. In other words, this finding also shows the significant impact of unanticipated of budget deficit on the government spending. It implies a weaknes of government finance management, in which government spending has not created new tax sources.
The architecture of New Zealand's divaricate shrubs in relation to light adaptation

Abstract The divaricating shoot habit is typified by a suite of architectural traits, quantified here using phylogenetic independent comparisons of three pairs of congeners, with or without the habit. We consider the hypothesis that the habit evolved as a structural photoprotection mechanism that maximises potential carbon fixation by minimising photoinhibition. Plants were grown in pots in full sun, or behind vertical screens transmitting c. 25, 52, or 73% sunlight. When shaded, all species shifted partitioning of biomass from stem thickening to leaf area expansion and occupied a larger crown volume for a given shoot biomass. Leaf numbers per stem length of divaricates and non‐divaricates were greater in the lower and upper canopies, respectively, consistent with the view that in divaricates outer branches protect inner leaves. However, leaf numbers per stem length showed no response to variation in high light receipt. Divaricates showed some traits typical of plants adapted to sunny habitats: smaller effective leaf size, lesser fractional partitioning of biomass to leaves, and greater foliage densities. Other traits of divaricates were typical of plants adapted to shaded habitats: lesser stem diameters, stem biomass per unit stem length, leader dominance, leaf area index, nd heights relative to crown diameters; and more horizontal twig orientations. Compensation for high costs of support of photosynthetic area in divaricates (leaf area per unit shoot biomass c. 1.3 m2kg‐1) compared with non‐divaricates (c. 5.5 m2kg‐1) would require a larger enhancement of net canopy photosynthesis than is likely to arise from avoidance of photoinhibition.
Limitations of Rare Event HPGe Experiments due to Muon-Induced Neutron Background

Experiments searching for neutrinoless double beta decay require very low background. Neutrons can produce background due to the production of long-lived radioisotopes. Monte Carlo simulations of the propagation of cosmic-ray neutrons and the production of muon-induced neutrons for different shielding materials were performed. GERDA data were analyzed to search for signatures of the Ge-77(m) and Ge-75(m) production. Upper limits on the production rates and the expected background were set.
Spectrophotometric determination of paracetamol in drug formulations with 1 – naphthol

Paracetamol with 1-Naphthol gave an azodye and the concentration of paracetamol was investigated spectrophotometrically. The dye formed with 1-Naphthol as a coupling agent followed Beer Lambert’s law within the range of 2 – 10 μgmL -1 of paracetamol at a lambda max (λ max ) of 505nm. The molar absorptively of the azodye coupled with 1-Naphthol was found to be 1.6973×104 dm 3 mol -1 cm -1 , r 2 was 0.9974. P value was found to be 0.013 at 95% confidence. LOD was 0. 02 μgmL -1 while LOQ was 0. 10 μgmL -1 . The coupling agent has been applied successfully for the analysis of paracetamol in pharmaceutical preparations such as boska, ibex, mixagrip, norgesis and procold with the recovery of 101.27 %, 98.98 %, 99.47 %, 98.28 % and 101.6 % respectively. The relative standard deviation of all the five samples ranged from 0 % to 0.76 %. The method used in the present study may be applied to the determination of trace amount of paracetamol on clinical samples as it is simple, accurate and precise, and also reproducible.
Studying Charge-Exchange in a Hybrid Ion-neutral Trap

Interactions between neutral and ionized atoms are medium-range, and the spiraling nature of these collisions can lead to long interaction times and large crosssections. The field of ion-neutral interactions is bolstered by methods from atomic physics, which allow us to accurately control and determine the quantum-states of the reactants. Trapping techniques allow us to study these interactions over a large range of energies, in order to observe interesting effects from the ultracold to hot temperature regimes. This control allows us to analyze and determine specific channels for the reaction, allowing for theoretical verification. The hybrid-trap enables the concentric trapping of a sample of cold atoms and ions. This work discusses our exploration into the controlled reactions in the Na−Ca system, including measurements of sympathetic cooling and charge-exchange rates which change as a function of energy and molecular state. The quantum-state distributions of Na in our magneto-optical trap is also explored, as well as its agreement and subsequent deviation based on a predictive model. The measurements of reaction rate reveal that there are reaction-energy thresholds in two separate reaction pathways, which can be attributed to either an endothermic reaction pathway or an activation barrier due to quantum-mechanical interactions.

Interconnected Markov models of dissimilar processes of operation of complex technical systems in long-term autonomous functioning

The article deals with issues of ensuring reliability and performance of tasks by complex technical systems. Operation of complex technical systems (CTS) is represented as two interconnected sub-process, developing in a different state spaces and times. Interconnected Markov models of dissimilar processes of operation of complex technical systems are considered in long-term autonomous functioning. This article shows a general scheme of two-stage modeling of operation of CTS, allowing to evaluate their effectiveness.
Cardio-Electopharmacology and Vasodilating Mechanisms of Quercetin

Quercetin, a kind of flavonoids, exerts the cardiovascular actions. In guinea pig ventricular cardiomyocytes, quercetin depresses the action potential duration (APD) and inhibited the underlying ionic currents ICaL. ,IKrec. IK1 in cardiomyocytes. In rat aorta, quercetin (0.1 to 100 μM) relaxed the contraction induced by pretreatment with 5 μM norepinephrine (NE) in aconcentration-dependent manner. NG-monomethyl-L-arginine acetate (L-NMMA) at 100 μM reduced the quercetin (100 μM)-induced vasorelaxation from 97.0 ± 3.7% (n=10, p<0.05) to 78.0 ± 11.6% (n=5, p<0.05). Endothelium removal as well attenuated the vasodilatation. In the presence of both 100 μM L-NMMA and 10 μM indomethacin, the quercetin-induced vasorelaxation was further attenuated by high K (30 mM) or 10 μM tetraethylammonium (TEA). Among KCa channel inhibitors, the quercetin-induced vasodilatation was attenuated by 0.3 μM apamin (sensitive to SK), but not by 30 nM charybdotoxin (sensitive to BK and IK). Under KCl-induced vasoconstriction, the quercetin-induced vasorelaxation was attenuated by PK-C inhibitors; Go6983 (α-, β-, γ-, δ and ζ-sensitive) produced stronger than Ro-31-8425 (α-, β-, γ- and e-sensitive). In rat mesenteric artery, the quercetininduced vasodilatation was almost resistant to both 100 μM L-NG-nitro arginine methyl ester (L-NAME) and 100 μM indomethacin. The L-NAME/indomethacin-resistant quercetin-induced was not modified by TEA (1 mM), but was attenuated by endothelium removal and 100 μM 18α- and 50 μM 18β-glychrrhetinic acids (gap junction inhibitors). Therefore, quercetin dilates the vascular smooth muscle mediated by endothelium-dependent and -independent mechanisms.
COMPARISON OF MODEL INTEGRATION APPROACHES FOR FLEXIBLE AIRCRAFT FLIGHT DYNAMICS MODELLING

Two approaches for the development of aircraft models integrating flight and airframe structural dynamics are compared. These models are intended for flight loads analysis and flight simulator application. The approaches combine available, agreed on flight mechanics and aeroelastic aircraft models from the respective engineering disciplines. The present work compares two methods, with different underlying assumptions, regarding accuracy, implementability, pre-processing and computing effort, as well as possibility to adapt the model components as a function of the flight condition.
Dynamics of environmental gradients on plant functional groups composition on the northern slope of the Fu-Niu Mountain Nature Reserve

The dominant and companion species in plant functional groups composition may reflect associations among plant functional groups and species replacement along environmental (elevation) gradients on the northern slope of the Fu-Niu Mountain Nature Reserve. Using community ecology techniques, these researchers examined the influences of elevation on plant functional group (PFG) dynamics and population interactions at elevations between 855 and 1920 m on the northern slope of the Fu-Niu mountain nature reserve. Importance values (IV) of every dominant and companion species in plant functional groups composition were calculated and the correlation between elevation and species IV was analyzed. We showed that elevation was the most important environmental factor affecting the distribution pattern of plant functional groups composition. IV of dominant and companion species in plant functional groups composition were significantly correlated with elevation gradient (P<0.05, P<0.01) on the northern slope of the Fu-Niu Mountain. Understanding the changes and their causes in these PFG is essential for further research of local ecosystem functions and the goal of sustainable development in the context of biodiversity conservation. This study may help policy makers formulate better plant biodiversity conservation and restoration plans. Key words: Plant functional groups, environmental gradients, importance values, elevation, correlation.
Genetic relationships of char distributed in the watershed border between three river basins in the eastern Chugoku Region, Japan.

Genetic relationships among a subspecies of white-spotted char, Salvelinus leucomaenis pluvius, distributed in the border area of three river basins in the eastern Chugoku region of Japan (the Sendai River, flowing into the Sea of Japan, and the Yoshii and Chigusa rivers, both flowing into the Seto Inland Sea), were investigated based on mitochondrial DNA cytochrome-b gene sequences. A total of 7 haplotypes were recognized and there were 8 polymorphic sites in a 447 bp fragment. Some haplotypes were shared by fish in two adjacent basins across passes, and some were confined to restricted basins. One haplotype estimated to be the oldest could be connected to ‘Gogi’, S. leucomaenis imbrius. Another haplotype, estimated to have derived in the most recent period, was observed in more than half the samples. There was a significant positive correlation between the geographic and genetic distances. These results suggest that genetic distance was more strongly determined by geographic distance than by river-basin location, and may support the possibility of range expansion of char by taking advantage of geologic events.
A Simple Predictive Performance Model of Solar Cell under Very Hot and Humide Climate

In the scope of solar energy-based electrical needs in rural tropical regions, the present article develops and confronts experimental power models from the using of manufacturer data and a new model made with the meteorological and electrical data acquired. These data are registered through an acquisition station around a monocrystalline photovoltaic panel, designed and realized in the scope of this work. After the acquisition of meteorological data, a choice of the most relevant meteorological variable as input vectors to express the output powers obtained was carried out. Around the Single-Diode model, seven models are performed with analytics equations, iterative methods and an optimization method with a multi-objective function to get internal parameters. The proposed experimental model is made by a combination of the solution got at STC of an iterative method, with the value of nameplate and the use of an open circuit voltage equation with experimental coefficient to predict power output in operating conditions, and it’s demonstrated more efficient. The optimization of a multi-objective function using Nonlinear Squares (NLS) through the Leveng-Marqued method to solve the parameter estimation of a PV panel has been well done and the results are useful, like classic iterative method and less time-consuming.
Inhomogeneous Planar Layered Chiral Media: Analysis of Wave Propagation and Scattering Using Taylor's Series Expansion

In this paper, an analytic frequency domain method based on Taylor's series expansion approach is introduced to analyze inhomogeneous planar layered chiral media for an arbitrary linear combination of TM and TE polarizations. In the presented method, electromagnetic parameters of inhomogeneous chiral media and also the electric and magnetic flelds are expressed using Taylor's series expansion. Finally, the validity of the method is verifled considering some special types of homogeneous and inhomogeneous chiral media and comparison of the obtained results from the presented method with the exact solutions.
Does Home Owning Smooth the Variability of Future Housing Consumption?

We show that the hedging benefit of owning a home reduces the variability of housing consumption after a move. When a current home owner’s house price covaries positively with housing costs in a future city, changes in the future cost of housing are offset by commensurate changes in wealth before the move. Using Census micro-data, we find that the cross-sectional variation in house values subsequent to a move is lower for home owners who moved between more highly covarying cities. Our preferred estimates imply that an increase in covariance of one standard deviation reduces the variance of subsequent housing consumption by about 11%. Households at the top end of the covariance distribution who are likely to have owned large homes before moving get the largest reductions, of up to 40% relative to households at the median.
Concurrent architecture for control of an autonomous driving vehicle

The autonomous robots and unmanned vehicles have been an intensive field of research in the last years for driverless cars and harsh environments exploration. An autonomous robot is a machine that can work in an independent way and subject to its own laws only, a system that can survive in the real-world environment without human intervention. Today many systems are available (e.g. GPS, Computer Vision) that aid the robots to survive, being the biggest challenge put all together and create an agent more intelligent, robust and reliable. The Department of Electronics, Telecommunications and Informatics of University of Aveiro in the last years has worked in the autonomous driving area. One point of this work has been the developing of autonomous vehicles for participation in the autonomous driving inside competition of the Portuguese Robotics Open, where it has participated since 2001. The high level software that controls the actual vehicle is based on a sequential structure that turns maintenance and integration of new modules in a complex task. Currently, there are modules to carry out several basic tasks, namely, image perception and integration, “world” representation, and creation of trajectory plans The aim of this work is the reorganization of the existent high-level software, following a modular and concurrent paradigm. The new software organization makes it easier to replace software modules and to add new functionalities, enhancing team work development and maintenance. The new structure is based on the existence of a central shared memory, like a blackboard, where the modules collect data that they need as well as publish produced data. This new architectural approach has been implemented in the ROTA robot and it was tested in the 2010 Portuguese Robotics Open (where it ranked 3rd). The proposed architecture links several existing systems and has as strongest points modularity and extensibility in concurrent environment with distributed information.
MAIN APPROACHES IN MEASURING INTANGIBLE ASSETS

In the 21st century much emphasis is being laid on intangible assets as they are major contributors to the market values of firms. They are vital strategic resources and are the critical sources of competitive differentiation. Wealth and growth of firms in today’s market place are governed mainly by them. Intangible assets and intellectual capital are the sources of value and the levers for sustainable business performance in today's competitive economic context. They are the sources of competitive advantages and above normal financial returns. [1] In fact, with intangibles, some of the basic economic rules seem to be breaking down. Developing indicators for measuring or assessing knowledge resources is difficult due to the intangible nature of knowledge. However, the measurement of knowledge is considered one of the key factors in the implementation of knowledge management strategy, along with culture, technology and infrastructure. Another reason for developing these indicators is that it can highlight the benefits and advantages of knowledge management.
Distribution and spread of environmental weeds along New Zealand roadsides

Most non-native weeds and other naturalised plants are in the early stages of invasion into New Zealand landscapes. For this invasion to be controlled, even partially, it is important to understand the dominant routes, mechanisms, and rates of weed spread across landscapes. With their linear corridors of disturbed habitats, roadsides are thought to play a large role in the spread of some weeds. We used both new surveys and existing data to assess which of the 328 environmental weeds listed by the Department of Conservation are most frequently found on roadsides, where, and whether distribution patterns are consistent with linear dispersal. We also analysed historical survey data for relationships between reserve weediness and proximity to roads. We surveyed 340 plots of 100-m-long stretches of roadside across four regions and found between 2 and 19 environmental weeds per plot; 128 species in total (Chao estimate 148). Especially abundant were agricultural species (weeds and cultivated), species that have been naturalised for well over 50 years, and species that disperse externally attached to vertebrates. While we purposefully sampled within 10 km of town limits, we found no strong effect of distance from town on roadside weed richness, including richness of just ornamentally sourced weeds. Instead, number of houses within 250 m and presence of an adjacent house or other residential structure were both important, as was presence of woody vegetation on and adjacent to roadsides. Reserves adjacent to roads had significantly higher weed richness than reserves further from roads, although the causal mechanisms are unclear. Our results suggest that while roadsides include suitable habitats for most environmental weeds, distributions are patchy and roads show little sign of acting as linear dispersal corridors, instead largely reflecting
Volatility and Commodity Price Dynamics in Nigeria

This study examines volatility and commodity price dynamics in Nigeria. This was estimated with the generalized autoregressive conditional heteroschedasticity (GARCH) and exponential GARCH, while granger causality test was used to examine the causality direction between domestic commodity prices and spot price of commodity derivatives. The result shows that 30% of volatility in the spot international commodity market can be explained by volatility in domestic and international export commodity prices, while international oil spot prices explains 7% volatility in prices of goods consumed locally and export commodity price index explains 16% of spot price of international commodity between 2000 and 2013 in Nigeria. Inflation and exchange rate is shown to be significantly related to spot price volatility which accounts for its volatility also. Hence, as such, the clamor for a more stable and robust revenue generating sector cannot be over emphasized - the so much talked about diversification.
Biogas production from goat and chicken manure in Malaysia

The aims of this study were, i) to determine the biophysical characteristics of the substrate using Chemical Oxygen Demand (COD), nutrient, heavy metal, Carbon to Nitrogen and Ammonianitrogen content analyses, and ii) to compare the biogas production between goat dung and chicken dung using industrial inoculum and traditional bokashi as catalyst. Bio-Methane Potential (BMP) test was used to measure biogas production in mesophilic condition for time duration of 20 days. The goat’s dung produced 2141 mL of biogas, higher than 1885.7 mL that of chicken dung using industrial inoculum . It was found that goat dung and chicken dung can be used as an energy source in a small scale industry as compared to the traditional bokashi where no methane gas was produced from the substrates.
