Automated Shelter Recognition in Refugee Camps

In June 2018, more than 68.5 Million people across the globe were reported to be ﬂeeing war or persecution. Within the United Nations, UNOSAT is the organ in charge of collecting demographic information based on satellite images of refugee camps to ensure reliable UN operations providing shelter, food and medicines to refugees and internally displaced people. This work aims at assisting UNOSAT analysts by providing them with an automated shelter detector to increase their efﬁciency and quality of the analysis. The tool is developed in two phases. The ﬁrst one consists of generating polygon masks of shelters using single point location generated by UNOSAT analysts in the past 10 years. The second uses the newly generated dataset to develop a model detecting multi-class shelters in new camp images without any analyst data. This report describes the model developed for the ﬁrst phase of the project. It consists of a ﬁne-tuned Mask R-CNN conditioned on analyst point shelter locations. On average, the tool achieves a recall of 88% and a precision of 81% compared to a human annotated shelter. A user-friendly interface allows the usage of the tool with a command line one-liner. Its usage is summarized in the report and detailed in the Github Repository. The latter also contains the entire python code of the developed tool. The results of all experiments are reported and the weaknesses of the model are discussed. Finally, possible further improvements and next steps required to achieve the development of the automated shelter detector tool are reported.
Microaneurysms (MAs) Detection using Mathematical Morphology

Diabetic retinopathy (DR) is one of the abnormalities on the retina. The diabetic retinopathy is a disease caused by diabetes and is considered as the major cause of blindness in working age population. The aim of this paper is to analyse the mathematical morphology namely extended minima function to detect the MAs. In this paper, the proposed methodology consists of five stages: pre-processing, detection of blood vessels, elimination of blood vessels, MAs detection and evaluation. The images were obtained from two database which are e-ophtha and ImageRet that provides the ground truth collected from several experts and a strict evaluation protocol. A performance analysis was performed based on sensitivity, specificity and accuracy of detection in retina image. The proposed method showed that the candidate of MAs has been successfully detected with average sensitivity obtained was 99.98 meanwhile 9.00 for specificity and accuracy 99.88.
Reduced order modeling of fluid/structure interaction.

This report describes work performed from October 2007 through September 2009 under the Sandia Laboratory Directed Research and Development project titled 'Reduced Order Modeling of Fluid/Structure Interaction. ' This project addresses fundamental aspects of techniques for construction of predictive Reduced Order Models (ROMs). A ROM is defined as a model, derived from a sequence of high-fidelity simulations, that preserves the essential physics and predictive capability of the original simulations but at a much lower computational cost. Techniques are developed for construction of provably stable linear Galerkin projection ROMs for compressible fluid flow, including a method for enforcing boundary conditions that preserves numerical stability. A convergence proof and error estimates are given for this class of ROM, and the method is demonstrated on a series of model problems. A reduced order method, based on the method of quadratic components, for solving the von Karman nonlinear plate equations is developed and tested. This method is applied to the problem of nonlinear limit cycle oscillations encountered when the plate interacts with an adjacent supersonic flow. A stability-preserving method for coupling the linear fluid ROM with the structural dynamics model for the elastic plate is constructed and tested. Methods for constructing efficient ROMs for nonlinearmore » fluid equations are developed and tested on a one-dimensional convection-diffusion-reaction equation. These methods are combined with a symmetrization approach to construct a ROM technique for application to the compressible Navier-Stokes equations. « less
A Survey of Regression Testing Techniques

: Regression testing is the process of validating the modified software to provide confidence that the changed parts of the software behave as intended and that the unchanged parts of the software have not been adversely affected by the modifications. Researchers have proposed many techniques for the different regression testing aspects. In this paper, we review the work which has been done so far in the field of regression testing. In addition, we will organize the surveyed techniques into categories according to the regression testing aspects.
Considering Nutrient Management in Future Western Forestry

During the past decade, the social environment for forest management in the western United States and Canada has been dynamic and often confusing. Amid this turbulence, some general trends can be seen that may affect nutrient status of forest soils and trees. Three categories of such trends are described: (1) social, economic, and political considerations; changes in the objectives or practice of forest management; and (3) technological advances. Many of the trends suggest that (2) fertilizer applications will be expanded to meet future demands for wood from western forests. Such applications must be finely targeted and closely monitored so that risks to other forest values are minimized and benefits are increased. The trends also indicate a need for improved communication and public education about the direct and indirect benefits of forest fertilization and measures taken to prevent fertilizer operations from impairing other forest resources and values. Predicting future trends is always difficult, and it is Social, Economic, and Political particularly so at present in the area of natural resource management. The social environment for forestry in the western United States and Canada has been dynamic and often frustrating and confusing during much of the past decade. Turmoil and uncertainty are likely to in­ crease as society comes to terms with diverse values and views of nature, and begins to recognize that forest land is a finite resource and must meet many needs. situation, we were uncomfortable with the "futuristic" nature of the topic assigned to us. After some discussion, we decided to minimize the long­ range and predictive aspects of the assignment and concentrate on identifying and discussing some trends and other important issues likely to shape future nut­ rient management activities.

A VALUE CHAIN GOVERNANCE FRAMEWORK FOR ECONOMIC GROWTH IN DEVELOPING COUNTRIES

This paper sought to develop a value chain governance framework to enhance the participation of the developing countries’ SMEs and other economic agents in the current non-inclusive global value chains. Due to their reliance on spot market transactions, SMEs in development countries continue to face economic prejudice in global markets. There is therefore a need for a value chain governance framework to further promote the upgrading of developing countries’ SMES in the global value chains. First to be done was a comprehensive literature study on the topic of value chain governance to unravel the major determinants of value chain governance. Second, a questionnaire was used to collect the data from a purposive sample of 332 managers working in the maize, cotton, soybean and tobacco value chains in Zimbabwe was employed to confirm the specific factors determining effective governance in a developing country’s value chains. The study confirmed that governance in developing countries’ value chains depended on the quality of collective action regimes, lead firms and trust present in the value chains. These factors have some important implications regarding any attempts by the managers and policymakers aimed at improving the operational efficiencies as well as deepening the integration of the developing countries’ SMEs within the value chains to ensure shared development and prosperity across the world. The study also outlines a transdisciplinary framework that can be used to enhance governance in developing countries’ value chains
The wild tapered block bootstrap

In this paper, a new resampling procedure, called the wild tapered block bootstrap, is introduced as a means of calculating standard errors of estimators and constructing confidence regions for parameters based on dependent heterogeneous data. The method consists in tapering each overlapping block of the series first, then applying the standard wild bootstrap for independent and heteroscedastic distributed observations to overlapping tapered blocks in an appropriate way. It preserves the favorable bias and mean squared error properties of the tapered block bootstrap, which is the state-of-the-art block-based method in terms of asymptotic accuracy of variance estimation and distribution approximation. For stationary time series, the asymptotic validity, and the favorable bias properties of the new bootstrap method are shown in two important cases: smooth functions of means, and M-estimators. The first-order asymptotic validity of the tapered block bootstrap as well as the wild tapered block bootstrap approximation to the actual distribution of the sample mean is also established when data are assumed to satisfy a near epoch dependent condition. The consistency of the bootstrap variance estimator for the sample mean is shown to be robust against heteroskedasticity and dependence of unknown form. Simulation studies illustrate the finite-sample performance of the wild tapered block bootstrap. This easy to implement alternative bootstrap method works very well even for moderate sample sizes.

Security for the Smart Grid – Enhancing IEC 62351 to Improve Security in Energy Automation Control

— Information security has gained tremendous importance for energy distribution and energy automation systems over the last years. Security for the smart grid is crucial to ensure reliability and continuous operation of the smart grid. However, the smart grid comes along with new use cases that impose new challenges on existing standards like IEC61850. IEC61850 offers standardized communication services and standardized data models for communication in energy automation, hence it is beneficial for the realization of the smart grid. IEC 61850 is flanked by the standard IEC 62351 that addresses security and specifies technical requirements, which have to be met by vendors. This paper provides an overview about the different aspects of security necessary to build and operate smart grid systems by describing current and new use cases. The focus lies on the current state of the standardization of IEC 62351 and its applicability to the described use cases. Moreover, this work discusses potential enhancements of the standard to address potential shortcomings through changed business and operation models leading to changed trust relations in new use cases like decentralized energy generation and load control. These shortcomings are addressed by describing potential enhancements for part 4 of IEC 62351 allowing multiple parallel distinguishable sessions based on the Manufacturing Message Specification and proper end-to-end authentication as well as authorization.
Heterologous Expression of the oL-Amylase Inhibitor Gene Cloned

The coding region for a secreted proteinaceous inhibitor of the human a-amylase (tendamistat; HOE 467) was identified by using a synthetic oligonucleotide probe. The gene is part of a 37-kilobase amplified genomic sequence found in an overproducing mutant of Streptomyces tendae. After subcloning, sequence analysis revealed an open reading frame of 312 base pairs preceded by a putative ribosome-binding site. The reading frame is 30 codons longer than necessary for the mature protein. This sequence coded for an amino-terminal extension of tendamistat and shows typical features of a signal peptide. After being cloned into Streptomyces vector plasmids and transformed to the heterologous host, Streptomyces lividans TK24, the gene was expressed, and the a-amylase inhibitor was correctly processed and secreted into the culture medium. The amount of secreted protein was dependent on the gene dosage and on the promoter arrangement.
Experimental analysis of density and compressive strain of porous metal with the use of Taylor test

The article presents a new experimental method of analysis of density and longitudinal engineering compressive strain (LECS) in porous ductile rod, plastically deformed with a Taylor direct impact experiment (Taylor DIE). Two essential singularities in the distribution of the LECS are revealed, namely: maximum of the LECS e r max occurs near the rod striking end (Fig. 2), and at high impact velocities ( U > 100 m/s) e r max decreases along with an increase of the rod initial porosity, this behaviour is inverse to that under static loading. The dynamical density – LECS curves for porous copper are also presented in the paper. According to the authors’ best knowledge, these singularities have not been published in available literature so far.
Overexpression of protein kinase C- (cid:100) increases tight junction permeability in LLC-PK 1 epithelia

Bechara Overexpression of protein kinase C- (cid:100) increases tight junction permeability in LLC-PK 1 epithelia. Am. J. Physiol. 275 ( Cell Physiol. 44): C544–C554, 1998. —The Ca 2 (cid:49) -independent (cid:100) -isoform of protein kinase C (PKC- (cid:100) ) was overexpressed in LLC-PK 1 epithelia and placed under control of a tetracycline-responsive expression system. In the absence of tetracycline, the exogenous PKC- (cid:100) is expressed. Western immunoblots show that the overex- pressed PKC- (cid:100) is found in the cytosolic, membrane-associ-ated, and Triton-insoluble fractions. Overexpression of PKC- (cid:100) produced subconﬂuent and conﬂuent epithelial morphologies similar to that observed on exposure of wild-type cells to the phorbol ester 12- O -tetradecanoylphorbol-13-acetate. Transepi- thelial electrical resistance ( R T ) in cell sheets overexpressing PKC- (cid:100) was only 20% of that in cell sheets incubated in the presence of tetracycline, in which the amount of PKC- (cid:100) and R T were similar to those in LLC-PK 1 parental cell sheets. Overexpression of PKC- (cid:100) also elicited a signiﬁcant increase in transepithelial ﬂux of D -[ 14 C]mannitol and a radiolabeled 2 (cid:51) 10 6 -molecular-weight dextran, suggesting with the R T de- crease that overexpression increased paracellular, tight junctional permeability. Electron microscopy showed that PKC- (cid:100) overexpression results in a multilayered cell sheet, the tight junctions of which are almost uniformly permeable to ruthenium red. Freeze-fracture electron microscopy indicates that overexpression of PKC- (cid:100) results in a more disorganized arrangement of tight junctional strands. As with LLC-PK 1 cell sheets treated with 12- O -tetradecanoylphorbol-13-ac-etate, the reduced R T , increased D -mannitol ﬂux, and tight junctional leakiness to ruthenium red that are seen with PKC- (cid:100) overexpression suggest the involvement of PKC- (cid:100) in regulation of tight junctional permeability.

Rice, R. E. & Hoffman, Z. T. (2018). Attention business press diffusion of attention technologies, 1990-2017. Organizations in the digital networked media environment must increasingly rely on data about audiences’ allocation of their attention in order to obtain positive returns on their marketing budgets, to provide better and more personalized services, or to archive more successful outcomes of health, political, or other campaigns or interventions. Thus a variety of attention technologies (tracking, storage, and analytics) and an attention brokerage industry have developed over time. These developments are grounded in concepts of the information and knowledge economy, information economics, media advertising models, the attention economy, and diffusion of innovations theory. After this contextualization, this study then analyzes how the business press represents the attributes associated with the diffusion of these attention technologies (relative advantage, compatibility, complexity, trialability, communicability, uncertainty, and reinvention) and new subdimensions of each, from 1990 to 2017) over time, and by promoting or adopting company.
Varietal evaluation and selection of yield-associated traits of Potato ( Solanum tuberosum ) using correlation and path analysis in haor area of Moulvibazar, Bangladesh

— The experiment was conducted with five high yielding varieties (HYVs) Potato BARI Alu-25, BARI Alu-35, BARI Alu-36, BARI Alu-37, BARI Alu-41 and one local potato variety as check at farmers field of haor area of Moulvibazar during the winter season of 2016-17. The number of tubers per plant was highest in local (48.33) and lowest in BARI Alu-25 (10.16). ). The highest yield per hectare (26.98 t and 26.88 t) were also observed in BARI Alu-35 and BARI Alu-37, respectively while the local variety produced the lowest yield per hectare (14.43 t). The correlation and path analysis revealed that the number of leaves per plant and tuber yield per plant had a highly significant positive interrelationship (r = 0.94) with tuber yield per hectare. Again, days to harvest and individual tuber weight also exerted a highly significant positive correlation ( r = 0.98 ) with tuber size. The number of leaves per plant, individual tuber weight, and days for harvest exhibited maximum positive direct effect (4.17, 3.76 and 3.13, respectively) on tuber yield per hectare. So these traits should be given preference for potato improvement in haor areas of Bangladesh.
Multivariate analysis of allozyme variation patterns in coastal Douglas-fir from 1 southwest Oregon coastal Douglas-fir from

1988. Multivariate analysis of allozyme variation patterns in southwest Oregon1• Can. J. For. Res. 18: 181-187. Isozyme data collected from megagametophytes of coastal Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) parent trees, representing 22 southwest Oregon breeding zones, were analyzed by multivariate techniques to describe the distribution of genotypic variation among and within breeding zones and to relate genotypic and envi­ ronmental variation. Data entered were mean haploid genotype scores obtained by averaging two haploid genotype scores from each parent tree. Haploid genotype scores were created from 27-locus haploid genotypes of two mega­ gametophytes collected from each of 1230 parent trees. Although principal components analysis did not indicate the presence of linkage disequilibria among loci, canonical discriminant analysis suggested that much more genotypic variation may be accounted for by breeding-zone differences than was evident from single-locus techniques. The first two canonical variables, which accounted for -250Jo of the genotypic variation, appeared to separate breeding zones on the basis of geographic and elevational differences among zones. Regressing canonical variable scores against location variables failed to provide a model attributing > lOOJo of genotypic variation to latitude, elevation, or distance from the ocean. Although canonical correlation analysis of mean haploid genotype scores with the same location variables produced two significant canonical variables accounting for 390Jo of the variation, little of the variation accounted for by the canonical variables was related to location variables. Although these results may be due
