An Angle Estimation to Landmarks for Autonomous Satellite Navigation

Celestial navigation is a completely autonomous navigation method, but the measure based on star sensor and infrared horizon sensor has a low precision. Especially its direction to the earth measured by infrared sensor leads to great deviation. Aimed by this consideration, we propose a vision-based method to obtain the direction to the earth in this paper. In particular, direction to the center of the earth is replaced by the direction of the landmark on the ground. And the location of landmark is determined by registering single image frames to reference image with a reliable matching method. Image matching based on feature has good performance on resistance of scale and rotation variation. Experiment results verify that the autonomous navigation for satellite with camera sensor has a higher accuracy than traditional methods. Comparing with SURF (Speeded-up Robust Feature), SIFT (Scale Invariant Feature Transform) achieves a higher precision despite of a moderate loss of efficiency. Introduction Currently, most of the satellite orbit measurement is based on ground station, such as USB (Unified S Band) and VLBI (Very Long Baseline Interferometry) [1]. The capability of autonomous navigation is in great demand for eliminating restriction of observation arcs. So many jobs have been done on satellite autonomous navigation technology. They mainly includes the following four kinds of typical methods: the celestial navigation, the magnetic navigation, star navigation and the relative navigation between stars. Compared with others, celestial navigation is a completely autonomous navigation method [2]. The typical celestial navigation is based on star sensor and infrared horizon sensor. Its schematic diagram is shown in Figure 1. Observing the angle γ between the direction of navigation star and the geocentric direction, orbit can be determined by the geometric relationships among the satellite, navigation star and the earth combined with the satellite orbit dynamics equation and kalman filtering methods [3]. Although this kind of navigation method which sensing horizon directly is simply and reliable, the navigation precision is lower. For the edge of the earth is not smooth, geocentric direction measured by infrared sensor leads to great deviation. Improvement on measure the direction to earth is in need. 5th International Conference on Environment, Materials, Chemistry and Power Electronics (EMCPE 2016) © 2016.

Coset Codes-Part 11: Binary Lattices and Related Codes

The family of Barnes-Wall lattices (including D4 and E,) of lengths N = 2" and their principal sublattices, which are useful in con- structing coset codes, are generated by iteration of a simple construction called the "squaring construction. " The closely related Reed-Muller codes are generated by the same construction. The principal properties of these codes and lattices, including distances, dimensions, partitions, generator matrices, and duality properties, are consequences of the general proper- ties of iterated squaring constructions, which also exhibit the interrelation- ships between codes and lattices of different lengths. An extension called the "cubing construction" generates good codes and lattices of lengths N = 3.2", including the Golay code and Leech lattice, with the use of special bases for 8-space. Another related construction generates the Nordstrom-Robinson code and an analogous 16-dimensional nonlattice packing. These constructions are represented by trellis diagrams that display their structure and interrelationships and that lead to efficient maximum likelihood decoding algorithms. General algebraic methods for determining minimal trellis diagrams of codes, lattices, and partitions are given in an Appendix.
MODal ENergy Analysis ( MODENA )

Energy methods like Statistical Energy Analysis (SEA) or Statistical modal Energy distribution Analysis (SmEdA), based on the well known equations of two coupled oscillators, are both limited when non-resonant contributions of modes are not negligible (typically in the case of cavity/structure/cavity coupling). In SEA, this non-resonant contribution can be taken into account introducing indirect coupling between subsystems. In SmEdA, the non-resonant contribution is more difficult to estimate as indirect coupling is not allowed. However, this issue can be a matter of importance to compute Transmission Loss (TL) of highly damped structures for example. The present work deals with an energy method, developped within the framework of SmEdA, which solves the system of equations of two coupled oscillators at pure tone, taking thus intrinsically into account the non-resonant contributions of oscillators. As in SEA or SmEdA, the net exchanged power between two coupled oscillators is proportional to the weighted difference of total energies of oscillators. The expression of a critical coupling strength is also proposed and may be related to classical weak coupling criterion of SEA. Extending equations obtained for two coupled sets of oscillators to the case of two linear continuous subsystems, one can compute easily frequency dependent modal energies of modes, total energies of subsystems, power transmitted between two modes and power dissipated. The theoretical bases and assumptions of the proposed MODal ENergy Analsys (MODENA) are first exposed and the case of two coupled oscillators is addressed. Then, Plate/Cavity and Cavity/Plate/Cavity systems are treated with MODENA and compared to an exact solution. Finally, it is demonstrated that the non-resonant contribution of a highly damped plate is correctly represented by MODENA.

Construction of Hybrid MPI-OpenMP Solutions for SMP Clusters

This paper proposes a middle-grain approach to construct hybrid MPI-OpenMP solutions for SMP clusters from an existing MPI algorithm. Experiments on different cluster platforms show that our solutions exceed the solutions that are based on the de-facto MPI model in most cases, and occasionally by as much as 40% of performance. We also prove an automatic outperformance of a thread-to-thread communication model over a traditional process-toprocess communication model in hybrid solutions. In addition, the paper performs a detailed analysis on the hardware and software factors affecting the performance of MPI in comparison to hybrid models.
Financing behavior of firms in tranquil and crisis period: Evidence from China

Abstract This study investigates the financing behavior of Chinese firms in tranquil and crisis situation over the period 2002–2014. We divide the sample into three sub-periods; pre-crisis, during-crisis, and post-crisis. The results indicate some noteworthy findings as this study incorporates firm and country-level factors. We find that the firms’ financing choice depends on the market conditions. The results show that Chinese firms have significantly decreased their dependence on leverage after the eruption of global financial crisis. Furthermore, we find that financial crisis of 2007–2008 has significantly affected the explanatory power of all factors. Moreover, profitability, size, and liquidity are important factors determining capital structure of the firm in financial crisis period.
Creative accounting for pensions. Why discretion may not be good for financial reporting.

Accounting standard setters worldwide are reviewing the financial reporting rules on pensions. The IASB, FASB and ASB require the funded status of a defined benefit pension plan to be reflected on the sponsoring company‟s balance sheet. Funded status equals the fair value of the fund‟s assets less its associated liabilities. Valuation of the assets presents few problems, but valuation of pension liabilities is less straightforward and requires a number of assumptions. Using data on 239 UK listed companies, this paper analyses the assumptions used to value pension fund liabilities under FRS 17 and IAS 19. We analyse the relationships between these assumptions and factors such as pension scheme funding position, company status, and audit firm. We contribute to the academic literature by standardising the liability valuations to eliminate bias arising from the underlying assumptions. We find evidence of selective “management” of two core assumptions which underpin the liability value. We conclude that companies exercise discretion to manage liability values downwards, thereby reducing the representational faithfulness of the reported pension figures. We suggest that discretion could be constrained by introducing tighter parameters on both salary growth rates and the definition of the high grade bond used to establish the discount rate.
Passionately Curious : How passion affects creativity in the context of supervisory support

In a sample of 400 employees working in 7 different large as well as moderately-sized manufacturing and engineering companies in and around Jamshedpur, India, I plugged a research gap recognized by creativity experts in the form of identifying a motivational mechanism other than intrinsic motivation that could affect creativity. Building on selfdetermination theory, I developed and tested a model in which harmonious passion (HP), identified as a novel motivational mechanism affects employee creativity with work engagement playing an important role in translating HP into employee creativity especially in an atmosphere of support from the supervisors. As hypothesized, HP positively related to employee creativity, work engagement partially mediated this relationship in a supportive atmosphere. Same-source common method bias was reduced by employing dyadic data, both from the employees as well as their supervisors.
Antinociceptive effects of epidural tramadol administration in dogs as an analgesic technique for experimental stifle surgery Efeitos antinociceptivos da administração epidural de tramadol em cães como técnica analgésica para cirurgia experimental do joelho

Tramadol is a centrally acting analgesic with μ-opioid and monoaminergic agonist effect. Ten healthy adult dogs were studied (mean ± SEM body weight 17.3 ± 3.8 kg), premedicated with acepromazine (0.05 mg/kg, IM), induced with thiopental (10 mg/kg, IV) and maintained under anesthesia with halothane in oxygen. Twenty minutes after starting halothane anesthesia, tramadol (1.0 mg/kg in 0.22 ml/kg of sterile water) was administered epidurally at the lumbo-sacral space. Surgery began 15 minutes later. Pulse and respiratory rates, systolic, mean and diastolic arterial blood pressure, and pulse oximetry were measu red before premedication (baseline), and at fixed intervals after anesthesia induction. Arterial pH, PaO 2 , PaCO 2 , HCO 3 - , and SaO 2 were measured at baseline, immediately before the epidural, and 60, 120, 240 and 360 minutes thereafter. Post-operative analges ia was evaluated for four hours using a scoring system. Statistically significant decrease in arterial blood pressure was observed following anesthetic induction. The PaCO 2 increased significantly from baseline at 60 minutes after epidural tramadol. The remaining variables were not significantly different from baseline values. No variables were significantly different from value s obtained immediately before tramadol administration. Intraoperative antinociception was considered adequate, with satisfactory post-operative analgesia for four hours. In conclusion, epidural tramadol seems to produce satisfactory antinociception and analgesia without causing clinically significant hemodynamic and respiratory depression in healthy dogs undergoing stifle
A Survey on Truth Discovery Methods for Big Data

Increasingly large numbers of embedded Smart phones, Sensors, PCs, Tablets, Computers connected to network, internet Medical data, Business transactions, Data are captured by sensors, Social media/networks, Banking, Marketing, Government data, etc are generating enormous amounts of unstructured data. This data creates new opportunities to extract more value for the areas for which it is needed. Recently, the Big Data is a challenging one by a dramatic increase of data from the physical world. One important property of Big Data is its wide variety, i.e., data about the same object can be obtained from various sources. Most of the time sources provide conflicted data for the same object. It is the challenging one to identify the “True Information” from the noisy information. To overcome such difficulties, Truth discovery methods are developed by estimating weight of the each source that is reliability of the sources. This survey focuses on the methods which are used to find out the true information from the conflicted data and comparisons of methods are used to select the appropriate method based on the types of data.
Title : Early Experience with a Hybrid Processor : K-Means Clustering

We discuss hardware/software coprocessing on a hybrid processor for a computeand data-intensive hyper-spectral imaging algorithm, KMeans Clustering. The experiments are performed on the Altera Excalibur board using the soft IP core 32-bit NIOS RISC processor. In our experiments, we compare performance of the sequential algorithm with two di erent accelerated versions. We consider granularity and synchronization issues when mapping an algorithm to a hybrid processor. Our results show that on the Excalibur NIOS, a 15% speedup can be achieved over the sequential algorithm on images with 8 spectral bands where the pixels are divided into 8 categories. Speedup is limitd by the communication cost of transferring data from external memory through the NIOS processor to the customized circuits. Our results indicate that future hybrid processors must either (1) have a clock rate 10X the speed of the con gurable logic circuits or (2) include dual port memories that both the processor and con gurable logic can access. If either of these conditions is met, the hybrid processor will show a factor of 10 speedup over the sequential algorithm. Such systems will combine the convenience of conventional processors with the speed of con g-
Quantifying the human impact on water resources: a critical review of the water footprint concept

The water footprint is a consumption-based indicator of water use, referring to the total volume of freshwater used directly and indirectly by a nation or a company, or in the provision of a product or service. Despite widespread enthusiasm for the development and use of water footprints, some concerns have been raised about the concept and its usefulness. A variety of methodologies have been developed for water footprinting which differ with respect to how they deal with different forms of water use. The result is water footprint estimates which vary dramatically, often creating confusion. Despite these methodological qualms, the concept has had notable success in raising awareness about water use in agricultural and industrial supply chains, by providing a previously unavailable and (seemingly) simple numerical indicator of water use. Nevertheless, and even though a range of uses have already been suggested for water footprinting, its policy value remains unclear. Unlike the carbon footprint which provides a universal measure of human impact on the atmosphere's limited absorptive capacity, the water footprint in its conventional form solely quantifies a single production input without any accounting of the impacts of use, which vary spatially and temporally. Following an extensive review of the literature related to water footprints, this paper critically examines the present uses of the concept, focusing on its current strengths, shortcomings and promising research avenues to advance it.
Reconceptualising the beta diversity‐environmental heterogeneity relationship in running water systems

SUMMARY 1. Beta diversity modelling has received increased interest recently. There are multiple definitions of beta diversity, but here, we focus on variability in species composition among sampling units within a given area. This facet can be described using various approaches. Some approaches ignore the spatial scale of the area considered (i.e. region limits), while some consider different region limits as a starting point for the analysis of beta diversity. 2. We focused specifically on the beta diversity–environmental heterogeneity relationship in running waters. First, we present two conceptual models, which assume either (1) strong environmental control among localities (riffle sites in our case) within each region unit (a region unit encompasses a species pool and can be a stream or a basin or an ecoregion) or (2) that the spatial level of a region unit affects the relative importance of mechanisms affecting variability in species composition among localities (i.e. among riffle sites) within each region unit. Second, we compared three recent studies that used similar methods to examine the beta diversity–environmental heterogeneity relationship, but which were based on different region units, comprising sets of streams or sets of basins or sets of ecoregions. 3. Our conceptual framework assumes that environmental control is not likely to be the sole mechanism affecting variability in community composition among localities within each region unit, but it is likely to be most important when dispersal rates are intermediate (i.e. among localities within a basin). In contrast, if dispersal rates are very high (i.e. among localities within a stream) or very low (i.e. among localities within an ecoregion), environmental control is in part masked by high dispersal rates or is prevented from occurring because not all species can reach all localities, respectively. Such scale dependency in the relative strength of environmental control might therefore transcend spatial scales from individual region units to the strength of the beta diversity–environmental heterogeneity relationship. We emphasise that the beta diversity–environmental heterogeneity relationship can only be tested across multiple region units. The results of three case studies are consistent with these predictions. Specifically, the beta diversity–environmental heterogeneity regression was highly significant across multiple basins, but not across multiple streams or across multiple ecoregions. 4. We suggest that researchers take spatial scale and region unit level explicitly into account when inferring the mechanisms structuring ecological communities and mapping variation in beta diversity. We also propose a unified terminology for studies examining the beta diversity–environmental heterogeneity relationship in running waters because inconsistent terminology is likely to hamper the progress of our science.
Distributed approach for Clock Synchronization Algorithm in WSN

-Wireless sensor network has been a field where node’s clock synchronization has been a huge problem from decades to successfully transmit the data from source to destination there have been many research works about clock synchronization in Wireless sensor network in the literature and so many methods and protocols are proposed. Existing time synchronization algorithms provide on average good synchronization between a whole network, however, as we show in this paper, neighbour nodes in a network may be synchronized poorly. We propose the Distributed Clock Synchronization Algorithm (DCSA) which is designed to provide accurately synchronized clocks between nearest-neighbours. DCSA works in a completely decentralized fashion: Every node periodically broadcasts its time information. Synchronization messages received from direct neighbours are used to calibrate the logical clock. The algorithm requires neither a tree topology nor a reference node, which makes it robust against link and node failures. Keyword: DCSA, FTSP, Mote, WSN
A CLOSED FORM ANALYTIC SOLUTION FOR COUPLED NONUNIFORM TRANSMISSION LINES

A closed form analytic solution is introduced for arbitrary Coupled Nonuniform Transmission Lines (CNTLs). First, the differential equations of CNTLs are written as a suitable matrix differential equation. Then, the matrix differential equation is solved to obtain the chain parameter matrix of CNTLs. Afterward, the voltage and current of lines are obtained at any point using the chain parameter matrix. The validation of the introduced solution is studied, finally.
Replies and revised text in response to two reviewer comments are identical to those published online

8 General: I enjoyed the paper and appreciate the challenges in linking NOx chemistry, the diurnal 9 cycle, and boundary layer effects. The discussion of limitations in the evaluation of the effects of 10 interferences was quite complete. It is clear that much has been accomplished but more remains 11 to be done. A peeve of mine that the various papers in this collection do not appear to have been 12 coordinated in the time Periods highlighted (particularly in the figures): For example, Gallee et al 13 provides details on model versus observed boundary layer depth for 26-28 December but the really 14 interesting chemistry is earlier in Periods II and III in Frey. Similarly earlier published work (Argentini 15 et al.) looked carefully at 10 January boundary layer behaviour but Frey et al. did detailed profile 16 measurements a day earlier. It would useful in collections such as these to identify specific Periods 17 of common interest prior to extensive analysis. 18 Reply: Thank you. The comparison of modelled boundary layer depth with observations based 19 on sodar measurements presented in Gallée et al. (2015) was possible on a few days only during 20 the OPALE campaign (see also reply to a similar reviewer comment to Gallée et al. (2015)). NOx 21 concentrations were measured from 23 November 2011 to 12 January 2012 (this work), HONO from 22 4 December 2011 to 11 January 2012 (Legrand et al., 2014), HOx radicals from 19 December 2011 23 to 9 January 2012 (Kukui et al., 2014), and CH2O from 14 December 2011 to 11 January 2012 24 (Preunkert et al., 2014). However, sodar measurements were only available on 12, 13, 18, 21 26, 27, 25 28 December 2011 and on 3, 4 and 10 January 2012. The best period to compare the MAR model 26 with sodar measurements was 26 to 28 December 2011, because it was the longest Period and also 27 included all chemical trace gases targeted during OPALE. 28 Regarding NOx observations, additional modelled and observed BL heights were available only 29 during Period III. (9-22 December 2011), which we’ll note in the manuscript. Unfortunately, the NOx 30 vertical profiles measured on 9 January 2012 can only be compared to modelled BL heights due to 31 the lack of sodar data. 32 Revised text 31298, Lines 8-13: The strong increase of NOx around 11 December 2011 falls into a 33 Period when FNO
The role of tourism toward economic growth in the local economy

This study analyzes the relationship between the number of tourists, tourism investment, government tourism spending, and economic growth in South Sumatra. It uses Granger causality model and simultaneous equation model to estimate the empirical model. The findings show that the number of tourists, the added value of the tourism sector, and the tourism spending of the tourism sector affect economic growth, while tourism investment does not affect the economic growth. In the second model, this study found that economic growth, tourism added value, tourism, and government tourism spending affect the number of tourists. This study implies that government policy has an important role in encouraging the tourism sector development which is indicated the contribution this sector on economic growth.
