Network Equipment Failure Prediction with Big Data Analytics

Minimising network downtime has been a challenge to all telecommunication service providers. One of the major causes for such downtime is equipment failure at various locations and rectification works are required on ad hoc basis. Therefore, if these failures can be predicted and rectified, downtime can be reduced. The system activities and operation parameters of these equipment are reported over the network and logged at a monitoring station. By studying these data from the equipment, many of the equipment related failures can be predicted to ensure minimal downtime and increase customer satisfaction. However, these data are massive and generated at very high velocity. A dynamic and adaptive algorithm is needed to process the huge amount of data and generate predictions based on trends and patterns. This paper presents a rule based analysis with regression technique and best fit line methods to predict the equipment failure. The warning occurrence pattern is studied on daily basis and a threshold for alarm signal triggering can be set. The output of this work suggests that the symptom of a failure started as early as 9 days before the failure while for prediction within 4 days before the failure has an accuracy of up to 99.9%
High performance PEDOT/lignin biopolymer composites for electrochemical supercapacitors

Developing sustainable organic electrode materials for energy storage applications is an urgent task. We present a promising candidate based on the use of lignin, the second most abundant biopolymer in nature. This polymer is combined with a conducting polymer, where lignin as a polyanion can behave both as a dopant and surfactant. The synthesis of PEDOT/Lig biocomposites by both oxidative chemical and electrochemical polymerization of EDOT in the presence of lignin sulfonate is presented. The characterization of PEDOT/Lig was performed by UV Vis NIR spectroscopy, FTIR infrared spectroscopy, thermogravimetric analysis, scanning electron microscopy, cyclic voltammetry and galvanostatic charge discharge. PEDOT doped with lignin doubles the specific capacitance (170.4 F g 1) compared to reference PEDOT electrodes (80.4 F g 1) The enhanced energy storage performance is a consequence of the additional pseudocapacitance generated by the quinone moieties in lignin, which give rise to faradaic reactions. Furthermore PEDOT/Lig is a highly stable biocomposite, retaining about 83% of its electroactivity after 1000 charge/discharge cycles. These results illustrate that the redox doping strategy is a facile and straightforward approach to improve the electroactive performance of PEDOT.
Diagnosis of protozoal and arthropod borne diseases

Protozoal and arthropod borne infections cause important diseases in dogs and cats. Some diseases, particularly arthropod borne, are endemic to some areas because they are transmitted by vectors restricted by geographical boundaries. However, these diseases are frequently also presented in non endemic areas as a result of the travel and importation of animals. In addition, some of these diseases are zoonotic and, therefore, of public health concern. This chapter looks at general laboratory diagnosis of protozoal and arthropod borne diseases and diagnostic tests for specific disease. Case examples are included.
Strain effects on the electronic and transport properties of TiO2 nanotubes

TiO2 nanotubes are promising materials for photocatalysis, solar cells and lithium ion batteries. Using first principles calculations, we found that strain is an efficient way to improve the electronic properties and transport properties of TiO2 nanotubes. For our modeled nanotubes, the armchair (12,12) nanotube shows a higher Young's modulus and Poisson ratio than its zigzag counterpart (12,0) nanotube due to the different orientations of Ti O bond topologies. An increase in axial compressive strain leads to a progressive decrease in the band gap for the armchair nanotube. Moreover, there is an indirect to direct band gap transition at a compressive strain of about 6% in the (12,12) nanotube. For both armchair and zigzag nanotubes, holes uniformly have a larger effective mass than electrons, in addition to the (12,0) TiO2 nanotube with compressive strain. It is found that the hole mobility is higher than its electron counterpart for the (12,12) nanotube, whereas the electron mobility is higher than its hole counterpart for the (12,0) nanotube with compressive strain. Our results highlight the tunable electron transport properties of TiO2 nanotubes that are promising for interesting applications in optoelectronic applications.
Effects of uniaxial compressive strain on the electronic transport properties of zigzag carbon nanotubes
Venue: Nano Research

Recently, substantial attention has been paid to the strain sensitivity of the carbon nanotubes' (CNTs' electronic properties. In this study, the relationships between the geometric structures and electronic states of zigzag CNTs under uniaxial compressive strain were investigated. We found that different factors dominate the electronic states of zigzag CNTs depending on the strain regions: the initial stage of the strain loading, which lasts until column buckling deformation begins, and the strain regions corresponding to column and shell buckling deformations. Because shell buckling deformation significantly increases the p orbital angle, the angle between the r orbital axis vectors of adjacent atoms, strong localization of the density of states (LDOS) occurs in the buckled area. We also analyzed the current able to pass through deformed CNTs using a tight binding based Green's function approach and determined that the current can be significantly suppressed by applying uniaxial compressive strain. Our method of predicting the electronic state of a deformed CNT based on the p orbital angle is expected to be useful for predicting the electronic properties of CNT based electronic devices and sensors.

Literature Mapping: Critical Factors in Industrialized Building System Plastic Formwork Application

Industrialised Building System (IBS) in Malaysia has been practiced for decades. The development of its formal practice parallels with the improvement of the built environment in the nation. One of the applications is on formwork. IBS plastic formwork has been promoted by Construction Industry Development Board Malaysia (CIDB) as an alternative to replace the conventional formwork system but the involvement from the public and private sectors in applying the IBS plastic formwork is seen reluctant. The aim of this study is to review the gaps that exist especially on awareness and readiness in application of IBS plastic formwork. Very relying on literature, this paper discovered a gap that is considered as critical factors in the successful of IBS plastic formwork application in construction industry. This paper aims to give new bits of knowledge in IBS formwork to upgrade the application of IBS plastic formwork as well as an alternative solution to enhancing the used of IBS in Malaysia.
Fusing Aligned and Non aligned Face Information for Automatic Affect Recognition in the Wild: A Deep Learning Approach
Venue: 2016 IEEE Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)

Face alignment can fail in real world conditions, negatively impacting the performance of automatic facial expression recognition (FER) systems. In this study, we assume a realistic situation including non alignable faces due to failures in facial landmark detection. Our proposed approach fuses information about non aligned and aligned facial states, in order to boost FER accuracy and efficiency. Six experimental scenarios using discriminative deep convolutional neural networks (DCNs) are compared, and causes for performance differences are identified. To handle non alignable faces better, we further introduce DCNs that learn a mapping from non aligned facial states to aligned ones, alignment mapping networks (AMNs) We show that AMNs represent geometric transformations of face alignment, providing features beneficial for FER. Our automatic system based on ensembles of the discriminative DCNs and the AMNs achieves impressive results on a challenging database for FER in the wild.
Landscape structure and climate affect plant invasion in subtropical grasslands

How do climate and landscape structure affect plant invasion process in south Brazilian natural grasslands? Location Natural grasslands across Rio Grande do Sul state, southern Brazil.  We selected 20 plots (2 km x 2 km each) situated in ten different grassland types in southern Brazil. In each grassland type, one plot was located in a region with remnant grassland cover 60% (conserved landscapes) in a paired design. In each plot, we surveyed the presence and cover of the four most important invasive species of grasslands in Rio Grande do Sul (Cynodon dactylon, Eragrostis plana, Senecio madagascariensis and Ulex europaeus) We used 12 variables related to climate and landscape structure (i.e. composition and configuration) for testing causal models of plant invasion using Akaike's information criterion for path analyses.  Empirical evidence on how climatic conditions and landscape structure can cause plant invasion in subtropical grasslands was provided through six causal models validated with path analysis. The models indicated that increased water deficit, higher density of roads and losses in natural grassland cover caused an increment of invasive plant cover. Further, invasion differed between plots located in conserved vs not conserved landscapes, resulting in not conserved grasslands having a higher level of invasion. E. plana, a perennial grass from South Africa, was the most important invasive species in the grasslands, in terms of frequency and cover.  Our results identified the general conditions that promote successful population growth of invasive plants in subtropical grasslands: water deficit, road density and land use, highlighting the effects of climate, landscape structure and human activity in the level of invasion across grassland types.
Bilateral perinatal testicular torsion: successful salvage supports emergency surgery
Venue: BMJ Case Reports

Perinatal testicular torsion (PTT) has poor rates of testicular salvage. Although rare, bilateral PTT carries the risk of anorchia. We present a case of a 2 day old term infant with acute onset right sided scrotal discolouration and tenderness. The infant was promptly taken to the operating theatre for emergency scrotal exploration. Bilateral extravaginal testicular torsion was identified, with the right testis appearing to have a more established ischaemic appearance compared to that on the left side. Intraoperative findings were representative of metachronous PTT with a short time period of only several hours separating the torsion events. Both testes were detorted and fixated in the scrotum. The infant made an uneventful recovery. Outpatient clinic review at 6 weeks and 6 months postoperatively confirmed no clinical evidence of testicular atrophy. Given the potential for contralateral torsion and the morbidity of anorchia, our experience supports the role for emergency scrotal exploration in suspected PTT.
A Dynamic and Model Based Approach for Performing Successful Multi Driver Studies

When designing driving simulator studies, sometimes high efforts have to be spent to make them successful. Some drivers may not behave as desired, leading to situations unforeseen by the developers. When looking at multi driver studies, where multiple drivers need to interact with each other in one virtual environment, the probability of performing a successful study is even lower, as the behaviour of the human drivers cannot be fully controlled. While [Oel15b] already proposed guidelines for the creation of such scenarios, this paper describes how the probability of success can be monitored and even enhanced during scenario execution. Therefore, it describes an approach where the probability of success is modelled and where the scenario is dynamically adapted to provide higher rates of success.
Femtosecond laser direct writing of microholes on roughened ZnO for output power enhancement of InGaN light emitting diodes.
Venue: Optics letters

A significant enhancement of light extraction efficiency from InGaN light emitting diodes (LEDs) with microhole arrays and roughened ZnO was experimentally demonstrated. The roughened ZnO was fabricated using an Ar and H2 plasma treatment of ZnO films pre coated on a p GaN layer. When followed by a femtosecond laser direct writing technique, a periodic array of microholes could be added to the surface. The diameter of the microhole was varied by changing the output power of the femtosecond laser. Compared to conventional LEDs on the same wafer, the output power of LEDs with roughened ZnOs and a microhole (diameter of 2 mm) array was increased by 58.4% when operated with an injection current of 220 mA. Moreover, it was found that LEDs fabricated with roughened ZnO and the microhole array had similar current voltage (I V) characteristics to those of conventional LEDs and no degrading effect was observed.
Linking public sector social media and e government website use to trust in government
Venue: Gov. Inf. Q.

This study examines how citizens' use of e government websites and public sector social media accounts relates to their satisfaction and perceptions of public sector trustworthiness. Drawing upon data from a 2012 sample of 1100 Seoul citizens, findings reveal that greater use of e government websites is negatively related to citizens' satisfaction and perceptions of public sector trustworthiness. Conversely, use of public sector social media accounts is positively related to satisfaction and perceptions of public sector trustworthiness. Drawing upon the concept of psychological distance, these findings are interpreted to suggest that forms of e government conducive to the transmission of less detailed information (social media) may be more effective at improving relationships between citizens and their government than forms of e government that are more commonly used to transmit detailed information (e government websites)
Bien etre professionnel et qualite de vie des enseignants quelles evolutions sur 15ans

En France, pres d'un million de personnes exercent la profession d'enseignant. Si la finalite du metier reste immuable, le contexte et les pratiques pedagogiques se transforment au fil des evolutions societales, des reformes et des reajustements du systeme educatif. Qu'en est il de l'evolution du bien etre des enseignants Objectif Quantifier l'evolution d'indicateurs de qualite de vie professionnelle et globale des enseignants au cours des 15 dernieres annees. Examiner l'homogeneite des variations au sein meme de la population enseignante, selon le sexe et le degre d'enseignement. Methodes Trois enquetes nationales postales, a caractere representatif, realisees aupres d'enseignants du secteur public (premier degre, second degre et superieur) en 2000 n 3482) 2005 n 3842) et 2013 n 2343) ont ete mobilisees. Les reponses aux items equivalents ont ete comparees apres standardisation sur le sexe, l'age et le niveau d'enseignement. Les indicateurs etudies concernaient les conditions de travail (temps de trajet, risques psychosociaux selon le modele de Karasek) le bien etre professionnel Maslach Burnout Inventory desir de changer de profession) et la qualite de vie (sante ressentie) Resultats La comparaison synoptique des chiffres obtenus pour les trois enquetes suggere, pour les enseignants sur 15 ans, une intensification des sources de stress lie au travail (augmentation de la demande psychologique et du temps de travail hors enseignement) un affaiblissement du bien etre professionnel (augmentation du desir de changement et de la symptomatologie d'epuisement emotionnel) et une degradation de la sante ressentie. Cependant, certains indicateurs restent stables comme le soutien social ou l'accomplissement personnel au travail. Par ailleurs, les evolutions observees ne sont pas homogenes selon le sexe ou le degre d'enseignement.  Ce constat d'un affaiblissement du bien etre des enseignants appelle de nouvelles etudes pour elucider les mecanismes sous jacents et mettre en lumiere des leviers permettant d'enrayer le phenomene.

Lorentz invariant and Lorentz non invariant aspects of a scalar tachyon field Lagrangian and the scalar tachyon Feynman propagator

A consistent theory of faster than light particles (tachyons) can be built replacing the standard Lorentz invariant approach to the quantum field theory of tachyons by the Lorentz covariant one, invoking a concept of the preferred reference frame. This is a mandatory condition imposed by the causality conservation. In this article some features of a Lorentz violating (but Lorentz covariant) Lagrangian of a scalar tachyon field are considered. It is shown that the equation of motion and Feynman propagator resulting from it are Lorentz invariant, while the Lorentz symmetry of the suggested tachyon field model can be defined as covariantly broken.

A multimodal approach to diabetic macular edema.
Venue: Journal of diabetes and its complications

Diabetic retinopathy is a common complication of uncontrolled diabetes. A complication is diabetic macular edema, which is the leading cause of blindness in patients with diabetic retinopathy. Historically, management of these conditions was laser photocoagulation with regulation of blood pressure, blood sugar, and cholesterol. The initial studies demonstrated that this treatment regimen prevented further visual deterioration but did not improve visual acuity. Novel studies identifying the presence of vascular endothelial growth factor (VEGF) in the eye with accompanying elucidation of diabetic pathophysiology allowed for the development of alternative therapies, namely antibodies against VEGF and corticosteroids. These two therapies revolutionized the management of diabetic macular edema by not only preventing vision loss, but also improving overall vision. In this review, we outline the major breakthroughs and underlying thought processes of the paradigm shifts that have occurred in management of these conditions. Further, we present how the evolving role of anti inflammatory and anti VEGF therapies, in a combinatorial approach, may provide further permutations to optimize treatment.
Nonlinear model predictive dynamic positioning control of an underwater vehicle with an onboard USBL system

This paper presents a novel optimization based approach for dynamic positioning (DP) of a fully actuated underwater vehicle equipped with an onboard ultrashort baseline transceiver to provide relative position information of two earth fixed transponders near the vehicle. The DP system error is defined by the transponders' positions compared to the desired values, which occur at the vehicle's target pose (position and orientation) The proposed DP strategy is composed of two loops in a hierarchical structure. In the kinematic loop, the nonlinear model predictive control is used to generate the desired velocity by optimizing a cost function of the predictive trajectories under the constraints of velocity and transponder bearings over a limited time horizon. In the dynamic loop, the neural network model reference adaptive control with pseudo control hedging is utilized to ensure the asymptotical convergence of velocity tracking errors in the presence of uncertainties associated with unknown model parameters, currents and thruster dynamics. The effectiveness of the proposed control scheme is illustrated by comprehensive simulations.
Dynamic Slot Partition Algorithm of Contention Avoid Positioning of UWB Label Based on Markov Model
Venue: AsiaSim/SCS AutumnSim

Multiple mobile UWB labels' positioning without conflict in a intensive environment is a problem, we put forward a method that takes the labels number as the only limited units in the envelope area with conflict free collision conditions for time slot length optimization, it is concluded the optimal capacity is estimated under the transition probability of markov and constraint functions. In order to keep balance between sampling data frequency of labels' effective positioning and increasing the utilization rate of time slot in each time frame as far as possible, we will construct dynamic time slot that is based on the algorithmic label numbers. Flight experiments were carried out to verify the result. We take a rectangle envelope as a multiple base station area for an example. Data processing and analysis are proved to optimize the positioning rate of each UWB label and to reduce the formation of large sparse time slot and empty slots, which is compared to a primary model of the fixed time slot in the fixed time frame.
