A STUDY TO INVESTIGATE THE POTENTIAL OF THE ACOUSTIC EMISSION/MICROSEISMIC TECHNIQUE AS A MEANS OF EVALUATING SLOPE STABILITY. FINAL REPORT

The results of a research program undertaken to investigate the feasibility of using acoustic emission/microseismic (AE/MS) techniques as a means of evaluating the stability of highway slopes, and specifically rock slopes, are discussed. The report includes a review of the literature available relative to slope stability and in particular the application of AE/MS techniques to slope stability monitoring; a review of the principles of the technique; a description of the apparatus and techniques utilized for low- and high-frequency AE/MS field studies; a detailed description of the specific AE/MS field studies carried out; a discussion of the feasibility of AE/MS slope monitoring and proposed routine field procedures; and an outline of proposed additional studies. The results indicate that the AE/MS technique is a feasible method for highway slope stability monitoring. Suitable methods were developed for transducer installation and data acquisition. The AE/MS character of simulated slope instabilities and highway background noise were investigated, and methods for reduction of background noise considered. AE/MS source location techniques were investigated at one slope site and found to provide suitably accurate location data. A special AE/MS system was developed for monitoring rock falls and found to perform well under typical field conditions. A high frequency AE/MS parametric system for routine slope stability monitoring was developed and field tested with encouraging results.
Deviations in the Gut Microbiota of Neonates Affected by Maternal Group B Streptococcus Infection

Background: Group B Streptococcus (GBS) infection is the leading cause of septicemia, meningitis, and pneumonia in neonates. Aberrant gut colonization in early life may predispose children to various diseases in adulthood. However, the associations between gut microbial changes and GBS infection is still unclear.Methods: We adopted a new microarray-based technique on neonatal meconium samples collected from 13 participants with mother’s GBS infection/colonization in vaginas and 73 uninfected controls.Results: The composition and diversity of meconium microbiota in GBS group were similar to that of healthy controls. However, we identified several specific taxa that were differentially abundant between the two groups (linear discriminant analysis (LDA) effect size (LEfSe): p<0.05, LDA>2.0). Particularly, the relative abundance of Lactobacillus paracasei was significantly reduced, indicating a role in GBS infection.Conclusions: Our study presented a series of bacterial species affected by GBS, thus providing novel evidence in support of initial intestinal microbiota dysbiosis in the neonates with mother’s GBS infection/colonization.
Speed sensorless control of ultrasonic motors using neural network

This paper presents a speed sensorless control for ultrasonic motors using a neural network. In the proposed method, a three-layered NN is used with offline training. The drive frequency, the root mean square value of input voltage and the surface temperature of USM are used as the inputs of NN for speed estimator. The validity of the proposed method is confirmed by experimental results.
Calendars on the new frontier: challenges of groupware technology

Groupware calendar systems--on-line, networked calendar software--illuminate difficulties in designing collaborative support technologies for effective, successful use. In the case of groupware calendars, the mundane but important practices of calendaring and scheduling create a potential dilemma for users: individuals' calendars must simultaneously support personal work and social coordination. The technology must meet a wide range of personal calendar support needs, but also employees must individually and collectively resolve serious issues about privacy and interpersonal boundary regulation. Furthermore, the role and function of the technology within the broader context of the organization impacts decisions about groupware participation and the nature of the technology's use. After a decade of slow adoption, groupware calendars are now being widely used and influencing behavior in some organizations. In an ethnographic investigation, I examine a high adoption case of groupware calendars at Sun Microsystems, where the openly-configured groupware calendar system allows an investigation into essential problems in collaborative systems design and operation. Calendar use at Sun has evolved beyond meeting scheduling, functioning instead as a distributed information system, supporting communication in unexpected ways. Contributions from the research include implications for groupware design, which address demands for individual support, group coordination, and opportunities for socio-technical adaptability.
Men perspectives on attending antenatal care visits together with their pregnant partners in Misungwi district, rural Tanzania: a qualitative study

Background: Mens’attendance with their pregnant partners at facility-based antenatal care (ANC) visits is important for maternal and child health and gender equality yet remains uncommon in parts of rural Tanzania. This study examined men’s perspectives on attending ANC with their pregnant partners in Misungwi District, Tanzania.Methods: Twelve individual interviews and five focus group discussions were conducted using semi-structured questionnaires with fathers, expectant fathers, and in-depth interviews were done to health providers, volunteer community health workers, and village leaders. Interviews were recorded and transcribed in Swahili and later translated to English. The research team conducted thematic analysis to identify common themes among interviews. Results: We identified two broad themes on the barriers to male attendance at facility-based ANC visits: (1) Perceived exclusion during ANC visits among men (2) Traditional gender norms resulting to low attendance among men.Conclusion: Attendance at health facility for ANC visits by men with their pregnant partners in the study areas were challenged by structural and local cultural norms. At the facility men were uncomfortable to sit with women due to lack of specific waiting area for men and that they perceived to be neglected. Local cultural norms demanded women to have secrecy in pregnancy while men perceived not to have a role of being with their partners during ANC visits.
Comparison of the Safety and efficacy of enucleation of nonmuscle-invasive bladder cancer versus transurethral resection of nonmuscle-invasive bladder cancer: a systematic review and meta-analysis

Purpose: Transurethral resection of bladder tumor (TURBT) via a wire loop has been regarded as a standard procedure dealing with nonmuscle-invasive bladder cancer (NMIBC) for a long time, and en-bloc resection of bladder tumors (ERBT) is a promising alternative to conventional transurethral resection of bladder tumor. A few studys assessing the two techniques were reported. The objective of our study is to review the published literature and compare en-bloc resection for non–muscle-invasive bladder cancer (NMIBC) with conventional transurethral resection of bladder tumor (TURBT) in terms of safety and efficacy. Methods: We performed a systematic review and meta-analysis based on randomized controlled trials (RCTs) and non-randomized controlled trials(nRCTs) and some retrospective studys which were searched and sreened. A systematic search up to the 1st of March 2019 was conducted in the following databases: PubMed, Web of Science,the Cochrane Central Register of Controlled Trials and Embase. Data such as resection techniques, morbidity, specimens’ quality, and recurrence were collected from the manuscripts.Results: Sixteen studies were included in this systematic review finnally.No statistical difference is detectded between the two techniques regarding operative time,the 2-year recurrence-free survival and the occurrence of ureterostenosis.Analysis of some complications showed that ERBT was better than TURBT for NMIBC, including obturator nerve reflex, cystic stimulation rate, bladder perforation, operation time,duration of catheterization, postoperation duration of postoperation bladder irritation and length of hospital stay. In addition, detrusor miss rate is lower in ERBT group,the 1-year and 3-year recurrence-free survival improved in the ERBT group than in the TURBT group. Conclusions: This systematic review and meta-analysis suggests that ERBT technique is a feasible, safe procedures that may provide an alternative treatment for NMIBC.
Identification and correction of besouro's faults: impact on test‐driven development experiments

Context. This thesis is framed in experimental software engineering. More concretely, it addresses the problems arisen when assessing process conformance in test-driven development experiments conducted by UPM's Experimental Software Engineering group. Process conformance was studied using the Eclipse's plug-in tool Besouro. It has been observed that Besouro does not work correctly in some circumstances. It creates doubts about the correction of the existing experimental data which render it useless. Aim. The main objective of this work is the identification and correction of Besouro's faults. A secondary goal is fixing the datasets already obtained in past experiments to the maximum possible extent. This way, existing experimental results could be used with confidence. Method. (1) Testing Besouro using different sequences of events (creation methods, assertions etc.) to identify the underlying faults. (2) Fix the code and (3) fix the datasets using code specially created for this purpose. Results. (1) We confirmed the existence of several fault in Besouro's code that affected to Test-First and Test-Last episode identification. These faults caused the incorrect identification of 20% of episodes. (2) We were able to fix Besouro's code. (3) The correction of existing datasets was possible, subjected to some restrictions (such us the impossibility of tracing code size increase to programming time. Conclusion. The results of past experiments dependent upon Besouro's data could no be trustable. We have the suspicion that more faults remain in Besouro's code, whose identification requires further analysis.
Developmental transcriptome and genes related to skin appendage differentiation in hedgehog (Atelerix albiventris)

Background Hedgehog spines are skin appendages that have evolved as a result of the interaction of their skin with the environment. However, such a differentiation mechanism during skin development leads to a high skin appendage diversity, the origins of which are still not fully understood. Spine-skin and hair-skin offer a natural model for the analysis of the genomic basis for the evolution of epidermal appendage formation. We performed a comparative transcriptomic analysis of hedgehog ( Atelerix albiventris ) at multiple developmental stages, and tried to explore the genetic basis for differentiation and development and the resulting expression of the spine-trait. Results A total 15,158 differentially expressed genes (DEGs) were identified. We determined the gene modules and programs corresponding to the various phenotypic traits at different developmental stages by WGCNA analysis. Objective analysis of gene module expression revealed that HIPPO, TGFB, MAPK and Wnt signaling pathways regulate the activation and cell proliferation and differentiation at the skin-appendage development stage. Further, the key genes encoding keratin, FGF, TEAD, and other proteins regulate molecular localization and the cell cycle for hair development and differentiation. Finally, we found a number of highly expressed immune genes in the skin, suggesting that hedgehog spines, unlike pangolin scales, have evolved independently to protect against predators rather than compensate for low autoimmune immunity. Conclusions The variability of gene expression profiles of hair-type and spine-type at multiple development stages, and key candidate genes and pathways at the molecular level might provide evidence that can help elucidate the genetic basis of skin appendage development and differentiation of hedgehog.
Study of the possibilities of 3D printing in ship modeling using the example of manufacturing a model of a small vessel for hydrodynamic testing in an experimental pool

The relevance of the work is determined by a fundamentally new direction of 3D printing in the manufacture of ship models for hydrodynamic testing. In this paper, we study the towing drag of a model of a small boat manufactured using additive three-dimensional printing technologies. Based on the dimensions of the 3D printers used and the technological parameters of working with them, as well as the design features of the test pool, small-sized vessels of a series of kayaks, kayaks and canoes, which are of sufficient length, but not too wide and high, were investigated as a prototype of the future model, which is ideal under the methods of additive manufacturing. A base of prototypes of vessels of this class has been compiled and a rationale has been given for the choice of the prototype vessel itself for research, including an analysis of the design of the vessels presented, the availability of design and technological documentation, as well as technological schemes for manufacturing the model. A 3D model of the vessel was developed, its optimization for 3D printing and analysis of geometric shapes for deviations from ITTC requirements. The study of deviations of the geometric shapes of the ship model from shrinkage deformations was carried out using 3D scanning with the development of a technological scheme for describing this process. When developing a 3D model, in the process of 3D printing, as well as processing the results of 3D scanning, modern software tools — FreeShip, Autodesk Inventor, Cloud Compare, and others — were used in the work. In the manufacture of the model, the new DPA adhesive compound formula was used, able to provide durable joints for PLA plastic products. It was found that the measurements prove the possibility of using 3D printing for the production of ship models for hydrodynamic testing, subject to all the nuances of the technology.

The 5Ss are intended to promote the discipline of cleanliness and tidiness as a set of shared values throughout the organization. First, materials and equipment are separated into those really needed and those not, with those not needed being thrown away. Next, each work area is organized for easy retrieval. Third, the workplace is cleaned and then standards introduced to maintain cleanliness. Finally, all previous tasks are made part of the daily routine. Keywords: 5S; just-in-time; toyota; JIT; quality
Low-Voltage Energy Efficient Neural Inference by Leveraging Fault Detection Techniques

Operating at reduced voltages offers substantial energy efficiency improvement but at the expense of increasing the probability of computational errors due to hardware faults. In this context, we targeted Deep Neural Networks (DNN) as emerging energy hungry building blocks in embedded applications. Without an error feedback mechanism, blind voltage downscaling will result in degraded accuracy or total system failure. To enable safe voltage down-scaling, in this paper two solutions based on Self-Supervised Learning (SSL) and Algorithm Based Fault Tolerance (ABFT) were developed. A DNN model trained on MNIST data-set was deployed on a Field Programmable Gate Array (FPGA) that operated at reduced voltages and employed the proposed schemes. The SSL approach provides extremely low-overhead (≈0.2%) fault detection at the cost of lower error coverage and extra training, while ABFT incurs less than 8% overheads at run-time with close to 100% error detection rate. By using the solutions, substantial energy savings, i.e., up to 40.3%, without compromising the accuracy of the model was achieved.
PRELIMINARY REPORT ON A REMOTE AUTOMATIC MONITORING AND PUBLIC INFORMATION SYSTEM FOR HAZARDOUS CONDITIONS

This report identifies and evaluates existing remote automatic monitoring and public information systems for both ice detection on bridges and flood monitoring at low-water crossings. The report encompasses all aspects of these systems, including hardware, software, communications systems, data processing, and meteorological services. This study provides a survey of various state agencies and their experiences with these systems. In addition, this report discusses three alternatives for statewide implementation of these systems. The alternatives examined are those considered by the Texas Department of Transportation, which include (1) the use of two turnkey systems throughout the state (one for ice detection and one for high-water detection); (2) multiple proprietary systems statewide (vendors could vary from district to district); and (3) a combination of components of various proprietary systems. The most feasible and cost-effective option is to allow each district to purchase a system that meets its needs while still remaining within budget. In order for this to work, systems from different vendors must be able to exchange information. Therefore, it is imperative that the systems purchased provide an open systems environment and use a standard data exchange protocol. The report concludes with suggestions for developing a set of implementation guidelines for a remote automatic monitoring and public information system for use during hazardous conditions.
Improving Reliability in Urban Public Transport in Strategic and Tactical Design

Reliability is one of the key indicators of level of service for public transport. In urban areas several sources lead to poor schedule adherence. If reliability is low, passengers will experience longer waiting times at stops and during transfers. Because of the relatively short journeys in urban areas, the increase of waiting times is significant. Next to the increased travel times, unreliability also results in less comfort and a smaller chance of having a seat, because of bunching of vehicles. Besides, travelers don’t appreciate uncertainty during their trip. Normally, reliability issues are analyzed and improved at the operational level of public transport. The hypothesis in this research is that already during the strategic and tactical planning phases reliability can be taken into account and be improved. This paper uses a case study of the tram lines in The Hague in The Netherlands to show the effect of unreliability for passengers. An analysis is made of actual travel time components for a better understanding of the problem. Solutions during the planning phases are suggested and analyzed. It is shown that using other parameter values in timetable planning than currently applied, leads to less extra waiting time for travelers. The effect of taking reliability explicitly into account when designing line length, stop spacing and coordination strategies is analyzed as well. This research thus demonstrates that improvements in reliability can already be achieved during the planning phases of public transport.
DESIGN AND CONSTRUCTION OF A SEAWATER SURVEY SHIP BUILT USING ALUMINIUM HONEYCOMB PANELS

A 13m long, 5m wide seawater survey ship (SWSS) was completed and has been in service for one year. This will be the first application of a honeycomb structure to a ship's main hull. The hull structure was constructed using aluminium braxing honeycomb panels (abbreviated BHP) assemblied by a TIG or MIG welding process. Using BHP panels is usually expected to be approximately 20% lighter than ordinary stiffened panels and also keeps the flatness of the welded panels. This paper describes the following features of BHP: materials, structural components and processing, characteristic, application to the SWSS, and welded joints. Also discussed is assembling and building of the hull of the SWSS, inspection results after one year of service and future prospects for the application of BHPs to ships.
Quality measures for libraries and information services

Academic libraries' services have changed very fast in the last twenty years. Nowadays, electronic resources, networks and the World Wide Web represent a large parcel of the library services. Academic librarians must manage staff, information in several supports, and technical activities to produce quality services. Quality services means resources and services which satisfy users' expectations. It is very clear that librarians must use management tools to run academic libraries services. These tools help them to assess services performance, to make decisions, to improve services and to achieve a better quality. In this context user needs and their perceptions, in relation to services offered by libraries and documentation centers, have been awakening the interest of professionals working with the management community and personnel. In an academic environment this lack of knowledge is considered to jeopardize teaching, research activities as well as the generation of new knowledge. The main proposal of this paper is to describe briefly two evaluation quality models for academic libraries: • The Portuguese investigation proposes an action model to measure the performance of the Universidade do Porto (UP)libraries. This tool is justified on the CAF - Common Assessment Framework (an auto-evaluation tool based on the European Foundation Quality Management Excellence Model), the Balanced Scorecard (BSC) and the Analytic Hierarchy Process (AHP); • The PAQ - Quality of Products and Services Evaluation Program of the SIBi/USP, based on the Model SERVQUAL, is an assessment research implemented in the academic libraries of Universidade de Sao Paulo (USP), in Brazil. The proposal has been presented as being viable and necessary in the management of the libraries of the SIBi/USP. Significant correlations were obtained between these two projects in order to improve customer satisfaction, staff satisfaction and performance for library services. It is made clear that dialogue among staff, academic library users and external partners is extremely important in an assessment process. The choice of indicators is the outcome of a participative performance evaluation process. These evaluation quality processes are, in other words, important tools to find new ways to motivate employers to stay with the organization that encourages growth.
Pemodelan Generalized Additive Model For Location, Scale, and Shape (Gamlss) Dengan Pemulusan Locally Estimated Scatterplot Smoothing (Loess) pada Kasus Hiv/Aids Di Jawa Timur

HIV / AIDS is a contagious disease that can attack all age groups of the population and is a health challenge in almost all over the world including Indonesia. Therefore, it is necessary to model HIV / AIDS cases for the factors that are suspected to influence them. One suitable method for estimating factors that influence HIV / AIDS is the Generalized Additive Model for Location, Scale, and Shape (GAMLSS). The GAMLSS method is flexible because it includes expansion of a good exponential family distribution to handle overdispersion data, continuous data, and discrete data. This research will apply GAMLSS semiparametric modeling with LOESS smoothing to find out the characteristics and models of HIV / AIDS cases in East Java in 2017. Based on the analysis, it was found that the variables that significantly affected were the number of homeless people, number of victims of drug abuse, population poor, and the number of fertile age couples using condom contraception with AIC value of 437,404, degree = 1 and span = 0.3, and the distribution used is Negative Binomial I.
