Additive manufacturing for novel structural health monitoring systems

Aerospace and automotive industries are some of the industrial sectors that are attr act d o structural health monitoring (SHM) systems. An SHM system should be: (1) integrated from the beginning of the structural design, (2) reliable, (3) light-weight and (4) able to inspect critical parts that are not easily accessible. Additive manufacturing (AM) is receiv ing momentum during the last years from many industrial sectors. The increase in design freedom offered by AM can be used in order to develop lightweight and complex structures. Typically these structures cannot be easily produced by subtractive conventional methods. We developed a novel approach for SHM systems. Our approach is based on fusing the aforementioned technologies – SHM and AM. Our novel approach is called the effective Structural Health Monitoring (eSHM) system. The eSHM system detects cracks in a structure by means of an integrated network of pressurised capillaries. The latter is integrated into a metallic structure which is produced by AM. For benchmarking, in traditional specimens (not produced by AM), the capillary can be machined. The current system has proven its effectiveness. The main objective of this work is to investigate the fatigue response of structures with an integrated eSHM system and the effectiveness of the eSHM system. The reliability of the eS HM system is evaluated during four-point bending fatigue tests. In the framework of this investigation specimens with integrated capillaries produced by AM and conventional material are tested with respect to the eSHM system. Furthermore, an optimization of various capillaries’ locations is also taking place. Heat treated conditions and autofrettaged conditions of samples are compared with conventional samples. It is concluded that an integrated eSHM system can be included on the initial design of an AM structure with promising results. The current system does not jeopardize the structural integrity of a structure while it enables one of the main challenges for SHM systems – SHM integration into the structure from the initial design.

A Method for Correcting Catches of Fish Larvae For the Size Selection of Plankton Nets

N=~, PePr where Pe is equal to 1 minus the probability of a larva avoiding the net and P r is equal to 1 minus the probability of a larva being extruded through the meshes, given that it has entered the net. Since an estimator for N can be obtained by combining and rearranging the above equations, ABSTRACT: Length distributions of fish larvae obtained with plankton nets are usually biased because large larvae avoid the net and small larvae are extruded through the meshes. Sueh bias is often corrected by determining the ratio between a standard net and a test net with either zero extrusion or . zero avoidance. However, when avoidance of the test net with zero extrusion or when extrusion through test net with zero avoidance differs from the standard net, then the usual method of correcting for size selection results in biased estimates. For such situations, we propose a method that explicitly considers both differential extrusion and differential avoidance and that provides estimates of variance for the corrected length-frequency distributions. The method was applied to length-frequency data for the Hawaiian anchovy or nehu, Encrasicholina purpurea. It was shown that aIm plankton net with 0.335 mm mesh dropped vertically through the water column during the day effectively samples nehu larvae only between 2.25 and 6.75 mm, roughly one-third of the total length range.
Hepatitis B virus infection in pregnant women in Baghdad

Al – Kindy Col Med J 2013; Vol. 9 No. 1 P: 42 Abstract Background: Globally, hepatitis B is one of the most common infectious diseases. Estimates indicate that at least 2 billion people have been infected with the hepatitis B virus (HBV), with more than 378 million people being chronic carriers. Those individuals at higher risk for acquiring HBV and transmitting disease like pregnant women should be screened for hepatitis B surface antigen (HBsAg) to prevent transmission by vaccination and operation. Aim of study: The aim of this study was to determine the prevalence of HBsAg and its associated parameters in pregnant women who referred to antenatal clinic in Baghdad Province. Methods: The 234 apparently healthy pregnant women and their families, husbands and children were selected as study subjects from among those who had attained prenatal care clinic in Baghdad province between 2010 to 2012. Serological test was done for HBV using ELISA test (Dialab REF:Z00360,LOT2052-2). Results: Of these, 234 cases were brought into the study. Their age were ranged from 16-42 years old. Based on a different parameters , women positive for HBV and their children were negative constitute the highest percentage 85.4% and lowest one was pregnant women who lived with positive family history of HBV were 8.9%. Conclusions: The seroprevalence of HBsAg was of moderate severity according to WHO. This finding would suggest for the introduction of routine screening for HBV to all pregnant women during the antenatal period, and that “at birth dose” vaccination is given to new born babies of mothers found to be HBsAg positive so as to reduce and prevent the spread of infection. However more data is required from larger studies to support the findings so that ultimately this can be recommended as a policy.
The Newton integral and the Stirling formula

We present details of logically simplest integral sufficient for deducing the Stirling asymptotic formula for n! It is the Newton integral, defined as the difference of values of any primitive at the endpoints of the integration interval. We review in its framework in detail two derivations of the Stirling formula. The first approximates ∑ n i=1 log i with an integral and the second uses the classical gamma function and a Fubini-type result. We mention two more integral representations of n!
Poster : Code-Reuse Attack Detection Using Sequential Hypothesis Testing in IoT

As in conventional computing systems, IoT devices are vulnerable to different types of attacks. Among a variety of possible attacks against IoT devices, codereuse attacks are dangerous in the sense that attacker can easily take malicious benefits from reusing the normal codes in IoT devices and it is not easy to detect these attacks. In order to protect IoT ecosystem from code-reuse attacks, we propose a statistical scheme to detect code-reuse attacks by scrutinizing the packets incoming into IoT devices. Through simulation study, we show that our proposed scheme efficiently and resiliently detects code-reuse attacks in IoT.
Stateful Functions as a Service in Action

In the serverless model, users upload application code to a cloud platform and the cloud provider undertakes the deployment, execution and scaling of the application, relieving users from all operational aspects. Although very popular, current serverless oﬀerings oﬀer poor support for the management of local application state , the main reason being that managing state and keeping it consistent at large scale is very challenging. As a result, the serverless model is inadequate for executing stateful, latency-sensitive applications. In this paper we present a high-level programming model for developing stateful functions and deploying them in the cloud. Our programming model allows functions to retain state as well as call other functions. In order to deploy stateful functions in a cloud infrastructure, we translate functions and their data exchanges into a stateful dataﬂow graph. With this paper we aim at demonstrating that using a modiﬁed version of an open-source dataﬂow engine as a runtime for stateful functions, we can deploy scalable and stateful services in the cloud with surprisingly low latency and high throughput.
Load Sensitive Power Saving Technique for 4G Mobile Network under Limited User Traffic

Power saving is one of the key factors of emerging 4G mobile network as well as in IEEE 802.16e wireless metropolitan area networks (Wireless MAN). An efficient power saving mechanism is the heart for the guarantee of a long operating lifetime for a mobile subscriber station (MS), because MSs are normally driven by rechargeable batteries. It is a vital factor for Base Station (BS) of the same network. One of the most important features of 5G mobile is the extension of battery energy 10 times greater than the present days. In this context, the evaluation of duration of sleep mode of BS or MS based on traffic load of a network is now a new era of research work. In this paper, such analysis has been done based on two statistical models: Poisson’s pdf and Engset pdf. The concept of complete sharing and partitioning of user group of teletraffic engineering is applied to measure the possibility of getting leisure time of BS or MS. Both the traffic models used in the paper are applicable in both limited and unlimited user network, i.e. in micro and fem to cellular network of 4G and 5G.
Winners and losers of conservation policies for European eel , Anguilla anguilla : an economic welfare analysis for differently specialised eel anglers

Recreational specialisation theory was coupled with a discrete choice experiment to understand eel, Anguilla anguilla L. , angler s heterogeneity in their reaction to regulatory changes and the associated welfare changes. Differently specialised eel anglers exhibited distinct preferences for catch variables and eel angling regulations. All anglers preferred slightly to moderately stricter regulations than are currently in place; however, such policies particularly benefited casual eel anglers. In contrast, advanced eel anglers would be most penalised by highly restrictive regulations as indicated by substantial reductions in economic welfare. Aversions to stricter regulations found for advanced anglers contradicted predictions from specialisation theory. From an eel management perspective, the implementation of some simple tools such as increased minimum-size limits will reduce angling mortality on eel and simultaneously increase the welfare of anglers. By contrast, highly restrictive eel angling regulations will result in considerable economic welfare losses of several million € per year for northern Germany alone.
Smartphone Tracking Application Using Short Message Service

----------------------------------------************************---------------------------------Abstract: Smartphone users are increasing rapidly in this ICT enabled society. With the phenomenal growth of Smartphone usage, the burglary of such tiny device is also increasing. Smart phones are easily lost, stolen or misplaced. Security is one of the main concerns for Smartphone users today. This paper proposes a model to return smart phones from any kind of missing. Smartphone become more valuable useful device because it contains more and more sensitive information. Considering the stored information, users are very much concerned to return their phone to maintain regular communication and sharing.
Nature and Evolution of Crust in Southern Lhasa, Tibet: Transformation From Microcontinent to Juvenile Terrane

The nature and pre‐Cenozoic evolution history of crust in southern Lhasa, which is crucial for our understanding of Indo‐Asian continental collision and Tibetan uplift during the Cenozoic, remains controversial due to a “missing” pre‐Mesozoic magmatic record. In this contribution, we report petrological and geochemical data for newly identified Paleozoic bimodal magmatism in the Zhengga area of southern Tibet. The magmatism comprises Late Devonian‐Early Carboniferous (366–353 Ma) amphibolite and two‐mica gneissic granite. The protoliths of the Zhengga amphibolite were gabbro and diorite with low SiO2 and high MgO, Cr, and Ni contents with high εNd(t) values of +3.3 to +8.0, variable and positive zircon εHf(t) of +0.9 to +11.2, and low zircon δ18O of 5.7 ± 0.2‰. These protoliths are proposed to have formed by decompression melting of asthenosphere during intracontinental back‐arc extension. In contrast, the granite has relatively high SiO2 and low MgO contents with much lower εNd(t) of −8.6 to −7.3, variable and negative zircon εHf(t) of −10.4 to −1.3, and high zircon δ18O of 9.4 ± 0.2‰ values and was most likely derived from an ancient metasedimentary source. This magma subsequently underwent recharge with minor amounts mafic magma followed by fractional crystallization of K‐feldspar in middle‐upper crust (~10–20 km) magma chambers. Using our new data, in combination with Nd‐Hf isotopes, we present the first comprehensive picture of crustal evolution in southern Lhasa. The southern Lhasa sub‐block is likely to have been a microcontinent that underwent extensive Phanerozoic crustal reworking and growth, rather than a Mesozoic‐Early Tertiary juvenile accretionary arc terrane.
Towards a Unified Analysis of Random Fourier Features

In this section, we provide some notation and preliminary results that will be used throughout the appendix. Henceforth, we denote the Euclidean norm of a vector a ∈ R with ‖a‖2 and the operator norm of a matrix A ∈ Rn1×n2 with ‖A‖2. Furthermore, we denote with ‖A‖F the Frobenious norm of a matrix or operatorA. LetH be a Hilbert space with 〈·, ·〉H as its inner product and ‖ · ‖H as its norm. We use Tr(·) to denote the trace of an operator or a matrix. Given a measure dρ, we use L2(dρ) to denote the space of square-integrable functions with respect to dρ. Lemma 1. (Bernstein inequality, Tropp, 2015, Corollary 7.3.3) Let R be a fixed d1 × d2 matrix over the set of complex/real numbers. Suppose that {R1, · · · ,Rn} is an independent and identically distributed sample of d1 × d2 matrices such that
Shooting Labels by Virtual Reality

As availability of a few, large-size, annotated datasets, like ImageNet, Pascal VOC and COCO, spawned the deep learning revolution that has disrupted computer vision research so dramatically, we argue that new tools to facilitate generation of many more may finally popularize data-driven AI throughout applications and domains. In this work we propose a new tool based on Virtual Reality (VR) which makes semantic annotation of 3D data as easy and fun as a video game. Besides, our framework allows for projecting the 3D annotations into 2D images, thereby speeding up a notoriously slow and expensive task such as pixel-wise semantic labeling.
Background research on DNS-related DDoS vulnerabilities

Distributed Denial of Service (DDoS) attacks are one of the most disruptive attacks in today’s Internet. These types of attacks are even more effective and more dangerous when they target or misuse core Internet infrastructure and services, such as the Domain Name System (DNS). The DNS is a fundamental pillar of the Internet’s core infrastructure, and its role is crucial not only for the translation of human-readable names into IP addresses but also for supporting plenty of widely used Internet applications, such as e-mail, VoIP, etc. In this document, we provide an overview of the MADDVIPR (Mapping DNS DDoS Vulnerabilities to Improve Protection and Prevention) project, a collaboration between the University of Twente and the Center for Applied Internet Data Analysis (CAIDA-UCSD). In Section 2, we introduce the project’s objectives and methodologies. In Section 3.1, we review the current state of the art in DNS vulnerabilities and attacks, including reflection and amplification attacks. In 3.2, we describe the most frequent attacks against the DNS system and their impact. In 3.3, we explain how typical misconfigurations that can impair DNS availability. Section 4 discusses countermeasures. Section 5 proposes some improvements.
Cluster care improves the efficacy of sequential invasive-noninvasive mechanical ventilation for AECOPD accompanied with type II severe respiratory failure

Objective: The aim of this study was to examine the effects of cluster nursing on AECOPD (acute exacerbation of chronic obstructive pulmonary disease) complicated with type II severe respiratory failure treated by the sequential invasive-noninvasive mechanical ventilation. Methods: Medical records of 92 patients with AECOPD accompanied with type II severe respiratory failure were retrospectively analyzed. Selected patients were given sequential invasive-noninvasive mechanical ventilation. Of these, 37 patients received routine care (sham group), while the other 55 patients received cluster care based on routine care (observation group). Total mechanical ventilation times, incidence of ventilator associated pneumonia, tracheal intubation times, success rates of ventilator weaning, reintubation rates, hospital stays, times of hospitalizations, and quality of life scores (by Seattle Obstructive Lung Disease Questionnaire), as well as nursing satisfaction, were compared. Results: Total mechanical ventilation times and tracheal intubation times of the observation group were shorter than those of the sham group (P<0.05). Incidence of ventilator associated pneumonia and reintubation rates of the observation group were lower than those in the sham group (P<0.05). The success rate of ventilator weaning in the observation group was higher than that of the sham group (P<0.05). Hospital stays in the observation group were shorter than those in the sham group (P<0.05). Quality of life and nursing satisfaction scores in the observation group were higher than those in the sham group after treatment (P<0.05). Conclusion: Cluster nursing care based on routine nursing care will improve nursing effects in patients with AECOPD and type II respiratory failure treated with sequential invasive-non-invasive mechanical ventilation. It will shorten total mechanical ventilation times, decrease incidence of ventilator-associated pneumonia, upgrade the quality of life of patients, and elevate nursing satisfaction scores.
Introduction to Evolutionary Algorithms June 26 , 2014 1 Darwinian Evolution In 1789

In 1789, Thomas Malthus wrote his Essay on the Principle of Population, in which he recognized that population growth rate is a function of population size, and therefore, if left unchecked, a population will grow exponentially. However, since environments have only finite resources, a growing population will eventually reach a point, the Malthusian crunch, at which organisms will have to compete for those resources, and will produce more young than the environment can support.
DESIGN OF STATUS OBSERVER FOR NETWORK CONTROL SYSTEM WITH TRANSFER DELAY

With the more and more larger scale of the control systems, many control systems are constructed as networks through fieldbus technology. Then some information such as sensor signal, and controller signal are transfered through the network. Because of the limitations of communication bandwidth and information collision, etc. it is inevitable that there is time delay with information transformation. In this case, a kind of status observer dealing with the time variant delay is designed, and two control strategies are investigated in terms of the network load. In the end, an experiment on a position servo system shows that the design concept is right and effective.
Neutralizing Antibodies of Inactivated Thai Enterovirus A71 Strain in Mice for Development of Enterovirus A71 Vaccine

Since enterovirus A71 is known as a pathogen which may cause severe complications as critical neurological manifestations, pulmonary edema, cardio respiratory failure and even death to infected children, therefore, the vaccine against EV-A71 infection has been expected to prevent such serious problems even in Thailand. In this study, we developed a vaccine candidate from a sub genotype C4 EV-A71 strain collected from a Thai fatal case. The target virus was firstly compared VP1 nucleotide and amino acid identities with other 13 Thai strains of one C4, three C5 and nine B5 sub genotypes. For nucleotide homologies, the virus shared 96.3%, 91.5%, and 90.3%, respectively, while it contained amino acid identities as 99.9%, 100% and 97.2%, with C4, C5 and B5 strains, respectively. Before vaccine development, the target virus was initially confirmed to be a single strain by inoculation of a single plaque serially from first cell culture to another, and the passage 9 still showed positive to the monoclonal antibody against EV-A71 by IFA. For production of the virus, EV-A71 could be cultured very well in Vero cells using roller bottles which the yield was 4.4 4.5 x 109 pfu/ml at day 3 4 post infection. By purification, total proteins left were monitored after 100 kDa tangential flow filtration and 10% – 50% sucrose density gradient centrifugation as 46.2% and 1.0% mean, respectively. Immunogenicity of the inactivated EV-A71 produced was tested in mice. After a single injection of 1 or 2.5 μg purified total proteins, it induced neutralizing antibodies against the homologous virus especially when with alum, as compared to placebo groups. After 2nd immunization, both 1 and 2.5 μg with alum induced many antibodies than those without alum and the groups of a single immunization. The 3rd immunization of the vaccines gave very much titer in all immunized groups even without alum; however, highest was 24,525 TCID50/ml after 4 weeks by 1 μg with alum. All titers seemed to maintain after 6 weeks studied. This study confirmed that an inactivated EV-A71 vaccine with triple injections is a good choice for further development.
Potential positive MRI contrast agent based on PVP-grafted superparamagnetic iron oxide nanoparticles with various repetition times

Objective(s): The present study aimed to evaluate the capability of synthesized and modified superparamagnetic iron oxide nanoparticles (SPIONs) as the positive contrast agent in magnetic resonance imaging (MRI) by investigating the effect of repetition time (TR) on the MRI signal intensity. Materials and Methods: SPIONs were synthesized using the co-precipitation method, and their surface was successfully modified with biocompatible poly (N-vinylpyrrolidone) (PVP). The effect of TR on the signal intensity (SI) of the PVP-grafted SPIONs was assessed in the spin-echo T1-weighted MRI images. Results: The results indicated the maximum SI at the concentration of 400 µmol Fe/l with the TR of 800-2,200 milliseconds. Moreover, the maximum SI was observed at the concentration of 75 µmol Fe/l, where TR was within the range of 2,900-6,400 milliseconds. Conclusion: According to the results, in addition to their capability as negative MRI contrast agents, PVP-grafted SPIONs could be preferred positive contrast agents with specific imaging parameters and have the potential application for early cancer diagnosis and perfusion measurements.
Project Plan Language Style Transfer on Non-Parallel Corpora

Language style transfer is a popular task in Natural Language Processing (NLP) which aims to modify the style of a sentence while keeping its content unchanged. Previous work mainly focuses on using adversarial methods, which are hard to train and struggled to produce high-quality outputs. In this project, we will first evaluate the performance of the state-of-the-art approaches, and then explore a novel approach, iterative semantic matching. Our model will be evaluated on three commonly used benchmarks: Yelp sentiment data set, formality style data set, and a democratic-versusrepublican political slants data set. Our approach can be applied to a wide range of applications, including stylistic dialogue systems, text formality conversion, and news text generation.
