Chapter 2 Data Storage

The data storage and retrieval services utilized by the ECS services layer will be provided by both a Database Management System (DBMS) and a hierarchical le system (see Figure 2.1). The DBMS(s) will manage and provide access to structured data as well as certain types of unstructured data (e.g., text data), whereas the le system will provide direct access to the large data sets that will be produced and archived at the various DAACs 1. The focus of this chapter is on storage system hardware and software technology (DBMS technology is discussed in Chapter 3). The design and implementation of the data storage system is driven by the following requirements 18]: Large storage capacity { the ECS system is expected to archive approximately 2 Terabytes per day over a 15 year period. High data access rates { the storage system architecture has to be able to provide a sustained bandwidth of 100 Mbyte/sec. High data reliability { the system has to be designed to provide high data reliability and 1 These data sets may be organized into structured data by a higher level DBMS as in 7, 11].
Density profiles and clustering of dark halos and clusters of galaxies

Density profiles of cosmological virialized systems, or dark halos, have recently attracted much attention. I first present a brief historical review of numerical simulations to quantify the halo density profiles. Then I describe the latest results on the universal density profile and their observational confrontation. Finally I discuss a clustering model of those halos with particular emphasis on the cosmological light-cone effect.
MBF 1999/2000 Page 2Bond Index Replication: A Principal Components Approach

A A p p p p r r o o a a c c h h Master Thesis Supervisors: Abstract In this work, we estimate the factors that determine German Government excess bond returns for maturities of 2,3,5,7,10,20 and 30 years, by using principal component analysis. Constructing factor mimicking portfolios allows us to find the economic interpretation of the factors we estimate. A three-factor model explains at least 97% of the variation in excess bond returns. The first factor can be interpreted as a level factor, the second as a steepness factor, and the third as butterfly. We use the estimated factors to replicate the J. Government Bond Index, and to backtest the model by computing the tracking error between the replicating bond portfolio and the J.P. Morgan Index. Over the whole period and without rebalancing, the tracking error amounts to 404 basis points per year. For shorter holding periods and yearly and monthly rebalancing, tracking error is decreasing to a minimum of 306 basis points per year, which is still inadmissibly high for practical purposes. This leads us to conclude that while principal component analysis works well for explaining the variance of bond returns, it cannot be used for out-of-sample index replication.
Paper title : Optimal Shielding / Spacing Metrics for Low Power Design

Noise arising from line-to-line coupling is a major problem for deep submicron design, and present technology trends are causing an increase in this type of noise. Common current methods to decrease coupling noise include shielding and buffering, both of which can increase overall power dissipation. An alternative method is spacing, which has the added benefit of improving the manufacturability (i.e. defect insensitivity) of the design. This paper explores the issue of coupling noise reduction, and proposes performance metrics that can be used by the designer to determine which of the alternative methods is best suited for a specific interconnect configuration.
Preparation and Photoelectric Properties of ZnO/TiO_2 Nanotubes Film Electrodes

ZnO/TiO2 nanotubes were prepared using ZnO nanorods as raw materials,which were synthesized by hydrothermal methods.Then its performance as an electrode of a dye-sensitized solar cell was investigated.The obtained products were characterized by SEM,XRD,EDX and N2 adsorption.Furthermore,the photoelectric properties of ZnO/TiO2 nanotubes film electrodes calcined at different temperatures were investigated by UV-Vis adsorption spectra and electrochemical workstation.It is found that the DSSC based on ZnO/TiO2 nanotubes calcined at 600℃ have optimum photoelectric properties,Jsc=2.28 mA/cm2 and Voc= 0.631 V,yielding the 0.66% maximum conversion efficiency.Additionally,after TiCl4 posttreatment,the performance of DSSC made from ZnO/TiO2 nanotubes are improved obviously and the photoelectric conversion efficiency is up to 1.06%.
IJESRT INTERNATIONAL JOURNA Optimizing Energy Efficiency in Wireless Sensor Networks ( WSN ) via Parallel Concentric Circle using Rotated

Nowadays, the interest cum research is picking up in area of Wireless Sensor Networks. Wireless sensor networks are being used in various monitoring applications (e.g., environmental monitoring and military surveillance) over a wide geographical region. In these applications, spatia an important role. One such query is the K samples based on a given query location and the number of samples specified (i KNN query processing techniques, which propagate queries and collect data along a predetermined itinerary, have been developed. Previous studies show that itinerary better energy efficiency than other existing algorithms developed upon tree how to derive itineraries for KNN query based on different performance requirements remains a challenging problem. In this research paper, we propose a Parallel Concentric (PCIKNN with Rotated itinerary) query processing technique that derives different itineraries by optimizing either query latency or energy consumption in Wireless Sensor N
3D Object Detection CS230 Project Report

3D object detection systems have become a core component in most of the recent autonomous vehicles systems. Autonomous vehicles are required to precisely detect and track the surrounding objects in real-time to achieve safe driving. Among the various sensors used in recent autonomous vehicles system, LiDAR, which measures distance between objects and the ego-vehicle has become a crucial sensor for 3D object detection systems. PV-RCNN [1] is a high-performing pointcloud based 3D object detector. However, PV-RCNN’s Two-stage detectors cannot adequately identify changing object scales, differing point-cloud density and clutter issues. I propose to introduce some changes in the module based on 2D deformable convolution networks that can adaptively gather instance-speciﬁc features from locations where informative content exists. The results are based on KITTI dataset [2].
DEBUSSY 2.0: the new release of a Debye user system for nanocrystalline and/or disordered materials

The new release of DEBUSSY is introduced, a free open-source package devoted to the application of the Debye function analysis of powder diffraction data from nanocrystalline, defective and/or nonperiodic materials. The general strategy of the suite remains unchanged, following a two-step approach managed by the CLAUDE and DEBUSSY programs, respectively. The first step essentially consists in generating a database where structural, size and shape information on a nanocrystal population is stored; the second step consists in the calculation, through the Debye scattering equation, of the total diffraction pattern using the previously generated database and a set of model parameters provided by the user and then optimized by the program. The novelties lie in the computational, modelling and graphical levels, and several new programs and features have been added. Among these are a new general comprehensive input file format (.ddb) for the database generation, the automatic management of the space-group symmetry and . cif file, new nanocrystal shapes, size-dependent site occupancy factors and thermal parameters for each atomic species, new lattice expansion functions, and a newly developed algorithm for calculating the standard errors of the optimized parameters. The CLAUDE suite also includes a program for calculation of the pair distribution function. Last but not least, a graphical user interface, which makes it easier to edit input files, execute the programs of the suite in a chain-like way, and plot the results in an automatic or custom manner, is provided.
Reconstructing temporally high resolution pediatric MRI scans from low resolution images

In this work, we leverage a deep learning pipeline for training a network to improve the resolution of MRI images, leading to shorter image acquisition times. Using a Generative Adversarial Network, we extend previous approaches and focus speciﬁcally on super-resolution of the MRIs of pediatric patients, which tend to have more artifacts. While our results show promise, further research into solving vanishing gradients and decreasing pixelation is needed.
Colorizing Grayscale Paintings using cGANs

Many of the world’s greatest artworks will never be seen. Too often, artworks are neglected, lost, damaged, stolen, or simply disappear. [1] In some cases, though, we are lucky enough to have black-and-white photographs taken of paintings before their loss. Here, we attempt to use Deep Learning to recolor grayscale images of paintings and discover what such lost or damaged paintings would have looked like. We use a pix2pix implementation of Conditional GANs (cGAN) to colorize grayscale paintings and apply transfer learning in an attempt to improve colorization accuracy, evaluated by using RMSE and VGG-16 classiﬁer accuracy. We found that transfer learning is not a viable strategy for our application, but found a set of hyperparameters that surpass the baseline level of model performance
The study of parent-regeneration relationships for wild cherry (Prunus avium L.) in Hyrcanian forests

The regeneration of forest trees is affected by the presence, dispersion pattern and specifications of parent trees. These effects were investigated and modelled in hardwood forests in the north of Iran. To do so, at first, fifty plots, each with a total area of 0.1 ha, were identified. Four subplots with a radius of two meters were then stabilized in each plot. The height and the root collar diameter of all the cherry seedlings were measured. Likewise, the diameter, basal area, and distance from the plot centre were appraised in the parent trees. The correlation and regression analyses were performed to evaluate the effects and to construct the models, respectively. The results showed that there was a positive and significant relationship between the presence, abundance, mean diameter, and total basal area of parent trees and the presence and abundance of seedlings. The logistic regression showed that the models based on the mean diameter of parent trees and abundance of parent trees could significantly predict the presence of regeneration. Only in 10% of the sample plots was the regeneration recorded without the presence of a parent tree. Due to the small number of established seedlings, while maintaining the existing parent trees, especially large trees, it is necessary to consider the proper management methods to promote and protect their regeneration. We recommend completing the natural regeneration of wild cherry by artificial regeneration and creating well-dimensioned canopy gaps.
Verfeinerung der Granatstruktur des Natrium-Lithium-Eisen(III)fluorids Na3Li3Fe2F12

The garnet structure known from some quaternary fluorides Na3Li3M2F12 (M = Al, Ga, In or transition metal) has been refined from single crystal data of Na3Li3Fe2F12: a = 1238,7 pm, space group laid, 224 independent reflections, Rg = [Zw(F0-Fc)/Zw Fa) = 0.018. The FeF6-octahedra are slightly elongated along a 3 axis with distances F e F = 192.9(1) pm and angles F F e F = 87.2/92.8°. Distances L i F = 185.0(l)pm result for the tetrahedral and N a F = 238.5/ 254.9(1) pm for the distorted cubic 8-coordination around the alkali ions.
Genre Classiﬁcation via Album Cover

Music information retrieval techniques are being used in recommender systems and automatically categorize music. Research in music information retrieval often focuses on textual or audio features for genre classiﬁcation. This paper takes a direct look at the ability of album cover artwork to predict album genre and expands upon previous work in this area. We use transfer learning with VGG-16 to improve classiﬁer performance. Our work results in an increase in our topline metrics, area under the precision recall curve, of 80%: going from 0.315 to 0.5671, and precision and recall increasing from 0.694 and 0.253 respectively to 0.7336 and 0.3812 respectively
ROCKING OF A MASONRY WALL: ANALYSIS AND EXPERIMENTS

In this work the experimental out-of-plane dynamic behavior of a rigid block has been investigated. The considered structural element is a tuff masonry wall clamped at the base, which starts to behave as a rigid block once the strength of the interface between mortar and brick is overpassed. Therefore, the rocking motion takes place on a base composed by the same block material. The results of free and forced oscillations are presented: the free responses were obtained applying different initial displacement amplitudes at the top of the wall. The forced behavior has been explored imposing harmonic input motions by means of a one-direction shaking table. Free rocking results were used to evaluate the coefficient of restitution, which takes in account the energy dissipation of the system. At each impact, the coefficient was calculated and correlated with top oscillation amplitude. For both forced and free motion, the relation between the block frequency and the oscillation amplitude has been obtained. Besides, the values of overturning was experimentally observed and reported. The equation of motion has been solved in MATLAB environment, considering the nonlinearity due to the change of the rotation hinge, and to loss of energy for each impact. Finally, the experimental results were compared with the numerical ones, both for the free oscillations and forced ones.

A Chairside Assessment of Antimicrobial Photodynamic Therapy andlaser therapy in the treatment of periodontitis: A clinical Study

Aim: The purpose of the study was to evaluate the efficacy of photodynamic therapy (PDT) and laser therapy as an adjunct to scaling and root planing in the treatment of periodontal pockets. Method: Thirty sites in ten individuals with probing pocket depth ≥ 5 mm were randomly divided into three groups, Group A (sites treated with scaling and root planning followed by laser therapy), Group B (sites treated with scaling and root planning followed by photodynamic therapy) and control was set as Group C (sites treated with scaling and root planning). Microbiological parameters (using chair side test kitBenzoyl-DL-arginine-B-napthylamide; BANA test) and clinical parameters (relative attachment level, probing pocket depth, plaque index, gingival index and sulcus bleeding index) were assessed at baseline and at two months. Results: Group A and Group B sites showed statistically significant improvement (≤ 0.005) in probing pocket depth, relative attachment level, plaque index, gingival index and sulcus bleeding index, whereas, Group C showed statistically significant improvement in plaque index and gingival index only. In case of microbiological parameter, a significant increase in BANA-negative sites was observed in Group A and Group B. Conclusion: The overall observations in the present study showed promising results with significant reduction in clinical parameters as well as BANA positive sites treated with either laser therapy or photodynamic therapy in comparison to sites treated with scaling and root planing alone. Hence, both the treatment modalities could be a beneficial adjunct to scaling and root planing.
Antibody-Mediated Transplant Rejection The Complement System and

Complement activation is an important cause of tissue injury in patients with Ab-mediated rejection (AMR) of transplanted organs. Complement activation triggers a strong inﬂammatory response, and it also generates tissue-bound and soluble fragments that are clinically useful markers of inﬂammation. The detection of complement proteins deposited within transplanted tissues has become an indispensible biomarker of AMR, and several assays have recently been developed to measure complement activation by Abs reactive to speciﬁc donor HLA expressed within the transplant. Complement inhibitors have entered clinical use and have shown efﬁcacy for the treatment of AMR. New methods of detecting complement activation within transplanted organs will improve our ability to diagnose and monitor AMR, and they will also help guide the use of complement inhibitory drugs.
Characterization of Reflection Seismic Systems in Glaciology by Data Analysis of the PALAOA-Observatory

With the critically intensifying global climate change the scientific interest in the Arctic and Antarctic increases continuously. Polar ice sheets are in a constant dynamic state and flow, depending on conditions of the subglacial bed. Information about the subglacial bed are important for estimating the ice sheet evolution and climate modelling. Seismic observations are basic methods to estimate spatial and physical properties of the subglacial bed. Different parameters that depend on the material and system characteristics like the attenuation, reflection coefficient and source amplitude drive the behaviour of elastic waves and furthermore the assessment of the results in glaciology. This leads to large uncertainties in defining the subglacial material. The PALAOA observatory is a set of calibrated hydrophones placed within the water column beneath the Ekström Ice Shelf, Antarctica. Its main purpose is to identify the underwater sea life soundscape, but can also be used for recording seismic shots triggered at the ice surface. The unique location of the hydrophones provides new opportunities of observing seismic signals, due to different ray paths in comparison to conventional methods. 24 shots triggered by a Vibroseis truck at the ice surface at 6 different locations are analysed. Ray paths and travel times of four signals of various reflections at each shot point are calculated and identified in the seismograms. The analysis of amplitudes of different signals in correlation with known properties of ice and water aims to provide estimations about attenuation of seismic waves depending on the shot point distance. This thesis presents a new method for analysing seismic data. The results highlight, that the time delay between the first signal arrival and the highest amplitudes (main signal) of single shots increases with an increasing shot distance. This is caused by sp-converted waves at the ice – water interface. Amplitudes show a strong decrease with increasing offsets. Several uncertainties complicate the seismogram interpretation which are discussed. Finally this thesis depicts in a first approach, how the usage of hydrophones could complement methods in observations of seismic data in glaciology and further constitutes the basis of prospective future studies.
Podovirus-Like RNA Polymerase That Has Myovirus Morphology and a EcoM-GJ 1 , a Novel Phage φ Bacteriophage Complete Genomic Sequence of

The complete genome of ␾EcoM-GJ1, a lytic phage that attacks porcine enterotoxigenic Escherichia coli of serotype O149:H10:F4, was sequenced and analyzed. The morphology of the phage and the identity of the structural proteins were also determined. The genome consisted of 52,975 bp with a G؉C content of 44% and was terminally redundant and circularly permuted. Seventy-five potential open reading frames (ORFs) were identified and annotated, but only 29 possessed homologs. The proteins of five ORFs showed homology with proteins of phages of the family Myoviridae, nine with proteins of phages of the family Podoviridae, and six with proteins of phages of the family Siphoviridae. ORF 1 encoded a T7-like single-subunit RNA polymerase and was preceded by a putative E. coli ␴ 70-like promoter. Nine putative phage promoters were detected throughout the genome. The genome included a tRNA gene of 95 bp that had a putative 18-bp intron. The phage morphology was typical of phages of the family Myoviridae, with an icosahedral head, a neck, and a long contractile tail with tail fibers. The analysis shows that ␾EcoM-GJ1 is unique, having the morphology of the Myoviridae, a gene for RNA polymerase, which is characteristic of phages of the T7 group of the Podoviridae, and several genes that encode proteins with homology to proteins of phages of the family Siphoviridae. Postweaning diarrhea (PWD) due to enterotoxigenic Esch-erichia coli (ETEC) is a major problem for the swine industry (2, 17, 36). The ETEC strains that cause this disease typically produce F4 (K88) or F18 fimbriae and belong to a small number of O serogroups, with O149 being dominant worldwide (2, 17, 19). Strains of this serogroup were responsible for recent exceptionally severe outbreaks of disease in pigs in Ontario (2, 26, 38). The outbreak strains were almost all O149:H10:F4, whereas O149 strains from earlier periods were all O149: H43:F4 (38). Since multidrug resistance is common among these ETEC strains (2, 32, 38), and the problem persists despite traditional approaches such as vaccination, antibiotic treatment, feed additives, and management strategies, it was decided to investigate the use of bacteriophages for prophy-laxis and therapy. Phage therapy has been effective in the prevention and treatment of experimentally induced diarrhea due to ETEC in neonatal pigs (46) but has never been investigated for PWD. We therefore used a mixture of 10 strains of O149:H10 ETEC from PWD as host strains in order to isolate phages by standard …
Touring the MetaCoq Project (Invited Paper)

Proof assistants are getting more widespread use in research and industry to provide certified and independently checkable guarantees about theories, designs, systems and implementations. However, proof assistant implementations themselves are seldom verified, although they take a major share of the trusted code base in any such certification effort. In this area, proof assistants based on Higher-Order Logic enjoy stronger guarantees, as self-certified implementations have been available for some years. One cause of this difference is the inherent complexity of dependent type theories together with their extensions with inductive types, universe polymorphism and complex sort systems, and the gap between theory on paper and practical implementations in efficient programming languages. MetaCoq is a collaborative project that aims to tackle these difficulties to provide the first fully-certified realistic implementation of a type checker for the full calculus underlying the Coq proof assistant. To achieve this, we refined the sometimes blurry, if not incorrect, specification and implementation of the system. We show how theoretical tools from this community such as bidirectional type-checking, Tait-Martin-L\"of/Takahashi's confluence proof technique and monadic and dependently-typed programming can help construct the following artefacts: a specification of Coq's syntax and type theory, the Polymorphic Cumulative Calculus of (Co)-Inductive Constructions (PCUIC); a monad for the manipulation of raw syntax and interaction with the Coq system; a verification of PCUIC's metatheory, whose main results are the confluence of reduction, type preservation and principality of typing; a realistic, correct and complete type-checker for PCUIC; a sound type and proof erasure procedure from PCUIC to untyped lambda-calculus, i.e., the core of the extraction mechanism of Coq.
