Block-Repetitive Iterated Processing for Software GPS Receiver: Dichotomized Search of Correlation Peak (Preprint)

Abstract : The software GPS receiver offers a block-repetitive iterated processing capability that is difficult, if not impossible, to realize with a hardware correlator-based GPS receiver. Applications of such block-repetitive iterated processing include iterative estimation of GPS signal parameters under high dynamics and nonlinearities, cross-correlation cancellation of multi-access interference, and multipath mitigation. In this paper, we first analyze the block-repetitive iterated processing capability offered by a software GPS receiver in both the acquisition and tracking modes as compared to conventional hardware correlator-based GPS receivers. Then we present a dichotomized search of the true correlation peak for delay estimation as an illustrating example of block iterative processing. This is in contrast to a conventional delay-locked loop (DLL) that moves several correlators of fixed spacing so as to drive the delay error discriminator to zero (an early-minus-late type). An advantage of this dichotomized search is its reduced sensitivity to multipath. This can be understood as if it implements a sequential software narrow correlator vs. parallel hardware narrow correlators. Since it adapts to data with a variable spacing, it is computationally more efficient than a software implementation that uses a fixed number of correlators with the same coverage. Simulation results are presented to show the multipath-desensitized delay estimation as compared to the theoretical multipath error envelope and to the thermal noise errors under various SNR conditions for different multipath parameters.
Novel integrated FBAR sensors: a universal technology platform for bio- and gas-detection

In this paper the feasibility of thin film bulk acoustic resonators (FBAR), for applications in bio- and gas-detection, is shown for the first time. Solidly mounted, ZnO FBARs with frequencies around 2 GHz have been fabricated on silicon substrates. The dependence of the FBAR mass sensitivity on the design of the layer stack has been investigated exhibiting an optimized sensitivity of 2.5 Hz cm/sup 2//pg. Using a common protein assay the capability of detecting bio-molecules has successfully been proved. Gas sensing has been demonstrated by coating the FBAR with a humidity absorbing polymer. A strong non-linear dependence of the humidity sensitivity on the thickness of the polymer coating has been found. When the polymer thickness is far less than the acoustic wavelength, a pure mass dependent response occurs, leading to a negative shift in resonance frequency. Moreover, as the polymer thickness becomes significant, acoustic influences affect the response and the shift becomes large and positive. A sensitivity to humidity of up to two orders of magnitude higher than that of comparably coated quartz crystal micro-balances has been observed.
Petrogenesis of lavas from Detroit Seamount: Geochemical differences between Emperor Chain and Hawaiian volcanoes

The Hawaiian Ridge and Emperor Seamount Chain define a hot spot track that provides an 80 Myr record of Hawaiian magmatism. Detroit Seamount (∼76 to 81 Ma) is one of the oldest Emperor Seamounts. Volcanic rocks forming this seamount have been cored by the Ocean Drilling Program at six locations. Only tholeiitic basalt occurs at Site 884 on the eastern flank and only alkalic basalt, probably postshield lavas, occurs at Sites 883 and 1204 on the summit plateau. However, at Site 1203 the basement core (453 m penetration) includes four thick flows of pahoehoe alkalic basalt underlying ∼300 m of volcaniclastic rocks interbedded with submarine erupted tholeiitic basalt. The geochemical characteristics of these alkalic lavas indicate that phlogopite was important in their petrogenesis; they may represent preshield stage volcanism. The surprising upward transition from subaerial to submarine eruptives implies rapid subsidence of the volcano, which can be explained by the inferred near‐ridge axis setting of the seamount at ∼80 Ma. A near‐ridge axis setting with thin lithosphere is also consistent with a shallow depth of melt segregation for Detroit Seamount magmas relative to Hawaiian magmas, and the significant role for plagioclase fractionation as the Detroit Seamount magmas evolved in the crust. An important long‐term trend along the hot spot track is that 87Sr/86Sr decreases in lavas erupted from ∼40 to 80 Ma. Tholeiitic basalt at Site 884 on Detroit Seamount is the extreme and overlaps with the 87Sr/86Sr‐143Nd/144Nd field of Pacific mid‐ocean ridge basalts (MORB). Complementary evidence for a depleted component in Detroit Seamount lavas is that relative to Hawaiian basalt, Detroit Seamount lavas have lower abundances of incompatible elements at a given MgO content. These lavas, especially from Sites 883 and 884, trend to extremely unradiogenic Pb isotopic ratios which are unlike MORB erupted at the East Pacific Rise. A component with relatively low 87Sr/86Sr and 206Pb/204Pb is required. Lavas erupted from a spreading center in the Garrett transform fault, 13°28′S on the East Pacific Rise, have this characteristic. A plausible hypothesis is mixing of a plume‐related component with a component similar to that expressed in lavas from the Garrett transform fault. However, basaltic glasses from Detroit Seamount also have relatively high Ba/Th, a distinctive characteristic of Hawaiian lavas. We argue that all Detroit Seamount lavas, including those from Site 884, are related to the Hawaiian hot spot. Rejuvenated stage Hawaiian lavas also have high Ba/Th and define a trend to low 87Sr/86Sr and 206Pb/204Pb. We speculate that rejuvenated stage lavas and Detroit Seamount lavas sample a depleted mantle component, intrinsic to the plume, over the past 80 Myr.
EFFECT OF DIETARY RED YEAST ( Sporidioboluspararoseus ) SUPPLEMENTATION ON SMALL INTESTINAL HISTOMORPHOMETRY OF LAYING HENS

This study aimed to evaluate the effect of dietary supplementation with red yeast (Sporidiobolus paraeoseus) on small intestinal morphology and determine the correlation of red yeast supplementation on intestinal morphology in laying hens. One hundred sixty laying hens were randomly assigned into four dietary groups as follows: basal diet (control) and basal diet with red yeast supplementation at 0.5 (R1), 1.0(R2), and 2.0(R3) g/kg feed. After 12 weeks of feeding, 16 hens (4from each group) were randomly euthanized and the small intestines collected to determines mall intestinal morphology. The villus height of the duodenum was higher in R1, R2, and R3 red yeast-supplemented groups compared to the control-treated group. However, dietary treatments did not differ significantly in terms of jejunal and ilealmorphology data (villus height and width, crypt depth, villus height/crypt depth ratio, crypt area, and muscularis mucosae thickness). A positive linear correlation was also observed between the level of red yeast supplementation and the width of jejunal villi (R2=0.8992). In conclusion, red yeast supplementation in the diet improved duodenal lumen health of laying hens by enhancing duodenal villus height.
Visual Efficiency Detection Index: A New Composite Measure of Visual Search

Visual search is an important component of our interaction with our surroundings, allowing us to successfully identify external cues that impact our spatial navigation. Previous research has established fixation duration, fixation count, saccade velocity, and saccade amplitude as important indices of visual search. We examined the Visual Efficiency Detection Index (VEDI) comprising multiple aspects of visual search performance into a single measure of global visual performance. Forty participants, 10 adults ages 22-48, and children ages 6, 8, and 10, completed tests of working memory and visual search in response to stimuli relevant to pedestrian decision making. Results indicated VEDI statistically relates to established indices of visual search in relation to their interpretability for human performance. The VEDI was also sensitive to developmental differences in visual search performance, suggesting insight to its utility in the developmental psychological literature.
Is it the natural rate or hysteresis hypothesis for unemployment rates in Newly Industrialized Economies

The focus of our study is on determining whether unemployment rates in 8 New Industrialized Economies conform to the natural rate hypothesis or the hysteresis hypothesis. To this end, we employ a variety of unit of unit root testing procedures to quarterly data collected between 2002:q1 and 2017:q1. In summary of our findings, conventional unit root tests which neither account for asymmetries or structural breaks produce the most inconclusive results. On the other hand, tests which incorporate structural breaks whilst ignoring asymmetries tends to favour the natural rate hypothesis for our panel of countries. However, simultaneously accounting for asymmetries and unobserved structural breaks seemingly produces the most robust findings and confirms hysteresis in all unemployment rates except for the Asian economies/countries of Thailand and the Philippines.
Changes in the Vascular Extracellular Matrix as a Potential Cause of Myocyte Loss via Anoikis in Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy

Objective: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a generalized vasculopathy caused by mutations in the NOTCH3 gene, leading to degeneration and loss of vascular smooth muscle cells (VSMC). The relationship between NOTCH 3 mutations and VSMC death is unknown. One possible cause of myocyte deficit may be anoikis, a special type of apoptosis due to loss or inappropriate cell adhesion to extracellular matrix. Method: To verify this hypothesis we examined immune expression of main compounds of vascular extracellular matrix (laminin, fibronectin and collagen IV) and selected metallo proteinases (MMP-2, MMP-3, and MMP-9) in cerebral, skin and skeletal muscle arterial vessels in autopsy material and biopsy specimens of CADASIL patients. Results: The immmune reactions revealed decreased expression of laminin and increased expression of collagen IV and fibronectin in arterial vessels. Moderately intense immune reactivity to MMP-9 and MMP-2 was present while immune reactivity to MMP-3 was absent. Conclusion: Quantitative and qualitative changes in vascular extracellular matrix found in CADASIL vessels may lead to VSMC loss via anoikis pathway.
Research on the Unmanned Aerial Vehicle Adaptive Control System based on Fuzzy Control and Chaos Mechanics

In this paper, we conduct research on the unmanned aerial vehicle adaptive control system based on fuzzy control and chaos mechanics. Four rotor aircraft is a kind of nonlinear systems with underactuated, strong coupling characteristic. Although in existing research, through the design of the control algorithm effectively inhibits both for flight control effect, but not fundamentally eliminate the effect of aircraft. Dynamic model of unmanned helicopter flight control system design is very approximate, need to gradually improve the modeling accuracy, so as to get the exact autonomous flight control, so you need to practice constantly required to modeling in the flight information, so the unmanned helicopter flight control system to have the ability to retrieve information modeling. This paper proposes the new idea on the issues that will be meaningful.
Vision-Based Object Fuzzy Recognition in Plain Industrial Environment by Contour Matching

The vision-based object recognition and location (VORL) technology can greatly increase the flexibility of production automation. To simplify some very complicated VORL systems while keeping the capacity of recogniting and locating many kinds of objects, the contour matching technology is introduced to the industrial VORL system consisting of object region detection, contour detection, contour matching, pose estimation and object location. To obtain the global optimal contour matching and decrease the computation complexity as much as possible, the dynamic programming with ordered contour points is adopted. Besides, based on the result of contour matching, the rotation angle can be estimated at a very little cost of computation complexity

Galaxy interactions. I. Major and minor mergers

Aims. We study galaxy pair samples selected from the Sloan Digital Sky Survey (SDSS-DR7) and we perform an analysis of minor and major mergers with the aim of investigating the dependence of galaxy properties on interactions. Methods. We build a galaxy pair catalog requiring rp < 25 kpch −1 and ΔV < 350 km s −1 within redshift z < 0.1. By visual inspection of SDSS images we remove false identifications and we classify the interactions into three categories: pairs undergoing merging, M; pairs with evident tidal features, T ; and non disturbed, N. We also divide the pair sample into minor and major interactions according to the luminosity ratio of the galaxy members. We study star formation activity through colors, the 4000 A break, and star formation rates. Results. We find that ∼10% of the pairs are classified as M. These systems show an excess of young stellar populations as inferred from the Dn(4000) spectral index, colors, and star formation rates of the member galaxies, an effect which we argue is directly related to the ongoing merging process. We find ∼30% of the pairs exhibiting tidal features (T pairs) with member galaxies showing evidence of old stellar populations. This can be associated either to the disruptive effect of some tidal interactions, or to the longer time-scale of morphological disturbance with respect to the bursts of the tidal induced star formation. Regardless of the color distribution, we find a prominent blue peak in the strongest mergers, while pairs with tidal signs under a minor merger show a strong red peak. Therefore, our results show that galaxy interactions are important in driving the evolution of galaxy bimodality. By adding stellar masses and star formation rates of the two members of the pairs, we explore the global efficiency of star formation of the pairs as a whole. We find that, at a given total stellar mass, major mergers are significantly more efficient (a factor ≈2) in forming new stars, with respect to both minor mergers or a control sample of non-interacting galaxies. We conclude that the characteristics of the interactions and the ratio of luminosity galaxy pair members involved in a merger are important parameters in setting galaxy properties.
Development of Gujarati WordNet for Family of Words

Gujarati is one of the 22 official languages of India. It is an Indo-Aryan language descended from Sanskrit. Gujarati wordnet is being built using expansion approach with Hindi as the source language. This paper describes experiences of building Gujarati wordnet. Paper discusses basic features of Gujarati language and evaluates suitability of Hindi language for expansion approach. Various issues related to synset linking using expansion approach and challenges related to language specific concepts(5) are also discussed This paper presents the preliminary analysis of Gujarati WordNet and the set of relevant computational tools. Although the design has been inspired by the famous English WordNet, and to certain extent, by the Hindi WordNet, the unique features of Gujarati WordNet are graded antonyms and meronym relationships, nominal as well as verbal compoundings, complex verb constructions. Gujarati WordNet would not only add to the sparse collection of machine-readable Gujarati dictionaries, but also will give new insights into the Gujarati vocabulary.
Comparison of Physicochemical Characteristics of Hot-boned Chicken Breast and Leg Muscles during Storage at 20℃

The aim of this study was to compare the physicochemical changes of hot-boned chicken breast and leg muscles. Chicken breast and leg muscles from 56 broilers were excised within a 15 min post-mortem (PM) and stored at 20 C. Physicochemical traits were determined at 0.5, 6, 12, and 24 h PM. The ultimate pH of leg muscle was higher than that of breast muscle (p<0.05). The content of glycogen in the breast muscle was relatively higher than that in the leg muscle until 6 h PM (p<0.05). R-values showing rigor mortis of breast and leg muscles were completed after or before 6 h PM. Breast muscle had less cooking loss than leg muscle (p<0.05). Drip loss did not significantly differ between breast and leg muscles with the exception of that at 6 h PM. The sarcomere length of leg muscle was relatively longer than that of breast muscle (p<0.05). The MFI of leg muscle was significantly lower than that of breast muscle (p<0.05). The shear force of leg muscle was lower than that of breast muscle at 6 and 12 h PM (p<0.05); however, that of both muscles did not significantly differ at 24 h PM.
Entropic uncertainty relations under localizations on discrete quantum groups

The uncertainty principle has been established within the framework of locally compact quantum groups in recent years. This paper demonstrates that entropic uncertainty relations can be strengthened under localizations on discrete quantum groups, which is the case if the dual compact quantum group $\mathbb{G}$ is the free orthogonal quantum group $O_N^+$ with $N\geq 3$ or if $\mathbb{G}$ admits an infinite $\Lambda(p)$ set with $p>2$. On the other hand, this paper explains the reason why such phenomena do not appear when $\mathbb{G}$ is one of the connected semisimple compact Lie groups, $O_2^+$ and the quantum $SU(2)$ groups. Also, we discuss the divergence of entropic uncertainty relations together with some explicit explanations.
From Theory to Practice—When and How to Implement Service Value Agreement

Traditionally, a Service Level Agreement (SLA) is used as an appendix in IT Service Management agreements to set expectations and delineate the service delivery description as well as the terms and conditions of delivery. However, SLAs are unable to imply and guarantee the added values expected by the customer. Service Value Agreement (SVA) is a newly developed framework that identifies the deliverable added values along with metrics to measure the quality and quantity of achievements in terms of business added values. The objective of this study is to expand the concept of SVA for Application Management (AM) services and suggest guidelines for its implementation in real business cases. This goal is fulfilled through the case study approach and outsourcing industry contributions. Authors suggest discussing the concept of SVA from early stages of the sales lifecycle and implementing it gradually during the steady state phase. Combination of Service Value Mapping approach and Piloting method is suggested for SVA proposition as an option with successful practical history.
Super studio: Clarity and ambiguity in probes

This article describes how Super Studio, an annual design class given at Art Center College of Design in Pasadena, California, has used cultural probes not only to bring clarity to the research object, but also to shape a pre-design research space through leveraging several types of ambiguity. The research model strengthens the analysis and interpretation of data from probes, while fostering design projects that reflect the daily realities (and the desires) of the population studied. Further, it provides a specific means for reconfiguring data as design interventions through the exhibition format. As the article's case study illustrates, the fluidity of the Super Studio research model is useful to the practice of designers as they assimilate the research into the design language and then apply it concretely.
Reduction of flow induced vibrations in hard disk drives by active control of dual-stage suspension

The trend in future generation Hard Disk Drives (HDD) is to contain more data and access this data faster. The latter is achieved by increasing the rotational speed of the disks. This, however, also increases the wind inside the HDD housing, generated by the rotating disks. In this report, we focus on two control strategies to decrease the effects of these wind disturbances (windage) on the data read-out of a HDD with a dual-stage suspension. The suspension is produced with two (coupled) piezo elements. Experimentally found models form the basis for the robust controllers. In the first part, non-collocated control is used to decrease windage effects. The readlwrite head is used to detect small position errors and the controller will actuate both piezos of the suspension at the same time. This method will show a great decrease within the range where windage plays the most significant role. However, this method relies on discrete position errors, so the bandwith of this controller is limited. The second part discusses the collocated control for windage. In this case the two piezos, present on the suspension, will be decoupled and used for both actuation and sensing. A new experimental model has to be found on which a new robust controller is designed and implemented. The general idea is to make the (mechanically weak) suspension behave stiffer. Also this method of control shows an improvement in the region where windage is active.
Revising Vegetation Scattering Theories: Adding A Rotated Dihedral Double Bounce Scattering To Explain Cross-Polarimetric SAR Observations Over Wetlands

Common vegetation scattering theories indicate that short wavelength Synthetic Aperture Radar (SAR) observations (Xand C-band) measure mainly vegetation canopies as the short-wavelength radar signal interacts mostly with upper sections of the vegetation. Furthermore, these theories also suggest that SAR crosspolarization (cross-pol) observations reflect only volume scattering. Consequently most SAR decomposition techniques assume that the cross-pol signal represents solely volume scattering. However, short-wavelength and cross-pol observations from the Everglades wetlands, south Florida, suggest that a significant portion of the SAR signal scatters from the surface and not only from the upper sections of the vegetation. The indication for surface scattering in wetland environment is derived from phase observable processed using interferometric techniques. The interferometric SAR (InSAR) observations reveal coherent phase signal in all polarizations and all wavelengths, reflecting water level changes beneath the vegetation. This coherent phase signal cannot be explained by neither volume scattering nor radar signal interaction with the upper sections of the vegetations, because canopies and branches are frequently move by wind. The only way that such coherent signal can be maintained and represents surface water level changes is when a multiple bounce from the vegetation and surface occurs. The simplest multi-bounce scattering mechanism that generate cross-pol signal occurs by rotated dihedrals. Thus, we use the rotated dihedral mechanism to explain the InSAR wetland observations and to revise the current vegetation scattering theories to accounts also for double bounce component in cross-pol observations.
