A Simple Estimation Method of Weibull Modulus and Verification with Strength Data

This study examines methods for simplifying estimation of the Weibull modulus. This parameter is an important instrument in understanding the statistical behavior of the strength of materials, especially those of brittle solids. It is shown that a modification of Robinson’s approximate expression can provide good estimates of Weibull modulus values (m) in terms of average strength (<σ>) and standard deviation (S): m = 1.10 <σ>/S. This modified Robinson relation is verified on the basis of 267 Weibull analyses accompanied by <σ> and S measurements. Estimated m values matched normally obtained m values on average within 1%, and each pair of m values was within ± 20%, except for 11 cases. Applications are discussed, indicating that the above relation can offer a quantitative tool based on the Weibull theory to engineering practice. This survey suggests a rule of thumb: wrought metal alloys have Weibull moduli of 10 to 200.
Design and Researechof a Tweet Alert System for Identifying Real Time Traffic using K-Means Clustering Algorithm

: At present, one of the major issues for an individual to meet their requirements is the disordered traffic. In order to resolve this issue, this paper focuses on designing an application to assign the true class label for each and every individual tweet related to the traffic words. If any message, which contains traffic-related information, it is being sent as an alert to the end users who are following the current user, or else the same tweet will be just posted on the user wall. In the digital era, the social networks have become a fascinating domain for every human for sharing and communicating their recent updates among each other. In order to implement this application, it chooses a compatible social media that is Twitter, for sending traffic related tweets to the followed users. This problem is solved by applying the K-Means algorithm for identifying the traffic-related keywords from the tweet and then clustering the traffic tweets and normal tweets into two separate categories.
Applications of Optimisation in Serious Games Design: An Integrated Framework

It is becoming increasingly difficult to adapt new teaching methods especially when addressing complex subjects of management such as operations management (OM) and supply chain management (SCM). Simulation-based serious gaming is one of the promising new approaches that leverage the learning ability for the current students – known as Digital era generation. Literature review shows few to no attempts to offer formal guidelines for the development process of serious games that are designed for education purposes. Combining and balancing objectives of learning, entertaining, keeping an active instructor role, while collecting real-time learning efficiency indicators is the main purpose of this study. The study proposes a comprehensive framework to underpin the development of simulation-based serious game – AUSUM (AUtomobile SUpply chain Management) – that can be used to support learning supply chain concepts such as supplier selection, production planning, order fulfilment, inventory management and more. Results demonstrate a very high satisfaction level from the learners on the usability and learning technique. Integrating optimisation with simulation has also enabled the game to offer different learning modes with different configurations in order to accommodate the level of learners and style of learning.
Mobile Throughput Guidance Inband Signaling Protocol

The bandwidth available for end user devices in cellular networks can vary by an order of magnitude over a few seconds due to changes in the underlying radio channel conditions, as device mobility and changes in system load as other devices enter and leave the network. Furthermore, packets losses are not always signs of congestion. The Transmission Control Protocol (TCP) can have difficulties adapting to these rapidly varying conditions leading to inefficient use of a cellular network's resources and degraded application performance. Problem statement, requirements and the architecture for a solution is documented in [Req_Arch_MTG_Exposure]. This document proposes a mechanism and protocol elements that allow the cellular network to provide near real-time information on capacity available to the TCP server. This "Throughput Guidance" (TG) information would indicate the throughput estimated to be available at the radio downlink interface (between the Radio Access Network (RAN) and the mobile device (UE)). TCP server can use this TG information to ensure high network utilization and high service delivery performance. The document describes the applicability of the proposed mechanism for video delivery over cellular networks; it also presents test results from live operator's environment.
R EINFORCEMENT L EARNING FOR L OCATION -A WARE W AREHOUSE S CHEDULING

Recent techniques in dynamical scheduling and resource management have found applications in warehouse environments due to their ability to organize and prioritize tasks in a higher temporal resolution. The rise of deep reinforcement learning, as a learning paradigm, has enabled decentralized agent populations to discover complex coordination strategies. However, training multiple agents simultaneously introduce many obstacles in training as observation and action spaces become exponentially large. In our work, we experimentally quantify how various aspects of the warehouse environment (e.g., floor plan complexity, information about agents’ live location, level of task parallelizability) affect performance and execution priority. To achieve efficiency, we propose a compact representation of the state and action space for location-aware multi-agent systems, wherein each agent has knowledge of only self and task coordinates, hence only partial observability of the underlying Markov Decision Process. Finally, we show how agents trained in certain environments maintain performance in completely unseen settings and also correlate performance degradation with floor plan geometry.
NULL HYPERSURFACES IN INDEFINITE NEARLY KAEHLERIAN FINSLER SPACE-FORMS

We study the geometry of null hypersurfaces, M , in indeﬁnite nearly Kaehlerian Finsler space-forms F 2 n . We prove new inequalities involving the point-wise vertical sectional curvatures of F 2 n , based on two special vector ﬁelds on an umbilic hypersurface. Such inequalities generalize some known results on null hypersurfaces of Kaehlerian space forms. Furthermore, under some geometric conditions, we show that the null hypersurface ( M, B ), where B is the local second fundamental form of M , is locally isometric to the null product M D × M D (cid:48) , where M D and M D (cid:48) are the leaves of the distributions D and D (cid:48) which constitutes the natural null-CR structure on M .
A 1 watt 68040-compatible microprocessor

A 68040-compatible microprocessor, optimized for portable applications, is presented. While maintaining the same speed and performance as its predecessor, this implementation achieves a 70% reduction in power consumption (before considering static power management techniques). The innovative low-power features and the cost/performance/power trade-offs of the design are discussed. A new metric is defined to compare the relative merit of quiescent states in microprocessors.
Zika virus NS2A and NS4A are the major antagonists that reduce IFN-β promoter activity induced by the MDA5/RIG-I signaling pathway.

Zika virus (ZIKV) is a mosquito-transmitted emerging Flavivirus causing the Guillain-Barré syndrome and microcephaly in adults and fetuses, respectively. Since ZIKV was first isolated in 1947, severe outbreaks have occurred at various places worldwide, including in the Yap Island in 2007, in the French Polynesia in 2013, and in Brazil in 2015. Although incidences of ZIKV infection and dissemination have drastically increased, the mechanisms underlying the pathogenesis of ZIKV and ZIKV related-diseases have not been sufficiently studied. In addition, despite extensive research, the exact roles of individual ZIKV genes on the viral evasion of host innate immune responses remain elusive. Besides, it is still possible that more than one ZIKV-encoded protein may negatively affect type I interferon (IFN) induction. Hence, in this study, we aimed to determine the modulations of the IFN promoter activity, induced by the MDA5/RIG-I signaling pathway, by over-expressing individual ZIKV genes. Our results show that two nonstructural proteins, NS2A and NS4A, significantly down-regulated the promoter activity of IFN-β by inhibiting multiple signaling molecules involved in the activation of IFN-β. Interestingly, while NS2A suppressed both full-length and constitutively active RIG-I, NS4A had inhibitory activity only on full-length RIG-I. In addition, while NS2A inhibited all forms of IRF3 (full-length, regulatory domain-deficient, and constitutively active), NS4A could not inhibit constitutively active IRF3-5D. Taken together, our results showed that NS2A and NS4A play major roles as antagonists of MDA5/RIG-I-mediated IFN-β induction and more importantly, those two viral proteins seem to inhibit induction of type I IFN responses in differential mechanisms. We believe this study expands our understanding regarding the mechanisms via which ZIKV controls innate immune responses and may pave way to development of ZIKV-specific therapeutics.
EASY ENSEMBLE WITH RANDOM FOREST TO HANDLE IMBALANCED DATA IN CLASSIFICATION

Imbalanced data might cause some issues in problem definition level, algorithm level, and data level. Some of the methods have been developed to overcome this issue, one of state-of-the-art method is Easy Ensemble. Easy Ensemble was claimed can improve model performance to classify minority class, and overcome the deficiency of random under-sampling. In this paper we discussed the implementation of Easy Ensemble with Random Forest Classifiers to handle imbalance problem in credit scoring case. This combination method is implemented in two datasets which taken from data science competition website, finhacks.id and kaggle.com with class proportion within majority and minority is 70:30 and 94:6. The results showed that resampling with Easy Ensemble can improve Random Forest classifier performance upon minority class. Recall on minority class increased significantly after the resampling. Before resampling, the recall on minority class for the first dataset (finhacks.id) was 0.49, and increased to 0.82 after the resampling. Similar results were obtained for the second data set (kaggle.com), where the recall for the minority class was increased from just 0.14 to 0.73.
A structure theorem for coupled balanced games without side Analysis)

The notion of ‘core’ for a game was deﬁned as an independent solution concept by Gillies and Shapley[l] [2]. The most basic issue is the core to be non-empty. The work of Bondereve[3] and Shapley[4] were on the balancedness condition for the non-emptiness of the core of a TU game and Scarf’s[5] work was on balancedness in NTU games. In this report, we will study a general problem: Given $nNTU$ games, is there a tight coupling between $nNTU$ games so that the common core has non-empty?
Edinburgh Research Explorer Bonobo personality

The study described in this chapter examines whether individual differences in six rating-based bonobo personality dimensions---Assertiveness, Conscientiousness, Openness, Attentiveness, Agreeableness, and Extraversion---are related to sex and age and behaviors and dominance. To these ends, the study tested predictions based on previous studies of human and chimpanzee personality, and bonobo behavior and socioecology. Sex and age differences in Assertiveness, Openness and Extraversion and correlations between these personality dimensions and behavior were consistent with our predictions. Conscientiousness showed associations with observed behaviors but requires further investigation as sex and age effects differed from those reported in humans and chimpanzees. Agreeableness and Attentiveness showed few associations with age, sex, and behaviors, indicating the need to further investigate validity of these factors. This study shows that personality dimensions in bonobos are correlated with sex, age and behaviors in ways that are consistent with what is known for bonobos and their socioecology. in social structure, behavior and life history; 2) test construct validity of the dimensions, by examining their associations with relevant behavioral variables derived from naturalistic observations and behavioral tests. We first test for age and sex effects of these behavioral variables and then look for associations between personality dimensions and behavioral variables. Based on studies done in multiple other species, we predict that the bonobo personality dimensions will show appropriate associations with observed behaviors. 3 days between

Structural characterization of stalk lignin from banana plant

Dioxane lignins from two fractions of banana plant ‘Dwarf Cavendish’ stalk (ﬂoral stalk (DL FS ) and rachis (DL R )) were structurally characterized by a set of spectroscopic (Ultravio-let (UV), FTIR, solid- and liquid-state NMR) and chemical degradation (permanganate (PO) and nitrobenzene oxidation (NO)) techniques. Despite both lignins are of HGS-type, strong structural differences were observed between them. Thus, DL FS showed almost twice the abundance of H and G units and almost half of the abundance of S units when compared to DL R . DL R possessed signiﬁcantly higher amount of (cid:2) - O -4 (cid:2) structures (0.32/C 6 against 0.12/C 6 ) andthemolecularweight(5400Daagainst3750Da)thanthoseofDL FS . About72%ofthecon-densed structures in DL FS are of (cid:2) -5 and 5–5 (cid:2) types, whereas 4- O -5 (cid:2) -diaryl ether structures were the most abundant condensed structures in DL R . Most of H units in both lignins are terminal phenolic coumarates linked to lignin substructures by ester bonds. Both lignins are structurally associated with suberin-like components in cell wall tissues. Structural features of stalk lignin were discussed in terms of possible restrictions for the kraft pulping of integral stem material.
Virtual design and construction of plumbing systems

Abstract Traditionally, the design coordination process is carried out by overlaying and comparing 2D drawings made by different project participants. Detecting information errors from a composite drawing is especially challenging and error prone. This procedure usually leaves many design errors undetected until construction begins, and typically lead to rework. Correcting conflict issues, which were not identified during design and coordination phase, reduces the overall productivity for everyone involved in the construction process. The identification of construction issues in the field generate Request for Information (RFIs) that is one of delays causes. The application of Virtual Design and Construction (VDC) tools to the coordination processes can bring significant value to architecture, structure, and mechanical, electrical, and plumbing (MEP) designs in terms of a reduced number of errors undetected and requests for information. This paper is focused on evaluating requests for information (RFI) associated with water/sanitary facilities of a BIM model. Thus, it is expected to add improvements of water/sanitary facility designs, as well as to assist the virtual construction team to notice and identify design problems. This is an exploratory and descriptive research. A qualitative methodology is used. This study adopts RFI’s classification in six analyzed categories: correction, omission, validation of information, modification, divergence of information and verification. The results demonstrate VDC’s contribution improving the plumbing system designs. Recommendations are suggested to identify and avoid these RFI types in plumbing system design process or during virtual construction.
Random Matrix Theories and the Problem of Metal-Insulator Transition (Mathematical Aspects of Quantum Information Chaos)

A general expression of $N$ joint level distribution used in random matrix theory, is examined along Balian’s axiomatic strategy, namely, (A) under a speciﬁed class of unitary transformations on the basis of metric on matrix spaces, and (B) $P( \{X_{j}\})$ satisﬁes a maximum entropy principle under two sorts of constraint, i.e. a geometric constraint and a level-density constraint. a canonical equilibrium state is employed for the so-called Hamiltonian level-dynamical system. In this way, it that the most general joint distribution must be of the above form with a possible pair-potential function $ \phi$ in a 2-dimensional space: $ 2\theta+(\frac{a}{r})^{4})$ , parametrized by $a >0$ and $ \theta;0\leq\theta<\pi/2$ .

Effect of Estrogen and Progesterone on Cellular Replication of Human Breast Tumors1

A total of 54 infiltrating carcinomas of the breast were studied for estrogen receptor concentration in the tumor cytosol and thymidine-labeling indexes. The results showed that there was no significant difference in the level of thymidine-labeling index between 22 primary and 32 metastatic breast cancers. No significant association between the levels of thymidine-labeling index and the presence or absence of estrogen receptors was observed. The effect of "physiological" doses of estrogen and progesterone on cell proliferative activity was studied by the level of thymidine-labeling indexes in the tumor cells in 10 patients with multiple skin and s.c. mÃ©tastases.Tumor biopsies were performed for labeling indexes both before and after hormonal treatment. The results showed that physiological doses of estrogen and progesterone induced a significant rise in thymidine-labeling index within 3 days after hormonal treat ment in seven of the 10 tumors. Of the seven tumors that showed a rise in thymidine-labeling index, three were estrogen receptor positive and four were estrogen receptor negative. Of the three nonresponsive tumors, one was estrogen receptor positive and two were estrogen receptor negative. The study suggests that estrogen and progesterone can induce cell rep lication in both estrogen receptor-positive and -negative tu mors.
OF P ESTICIDE A DDITION S EQUENCE ON THE REPARATION OF P HYTOSANITARY S PRAY OLUTIONS

- The addition of adjuvants to herbicide solutions is aimed at preserving or enhancing the biological effect of treatment. However, it is commonly performed without knowledge of the physicochemical interactions between products. This study aimed to assess the effects of different addition sequences of the herbicide aminopyralid + fluroxypyr and adjuvants in the preparation of phytosanitary spray solutions on the surface tension and contact angle. Two experiments were carried out with herbicide doses of 1 and 2 L ha -1 associated with the adjuvants mineral oil (MO), silicone-polyether copolymer (SIL), and a mixture of phosphatidylcholine (lectin) and propionic acid (LEC), all at a proportion of 0.3% v v -1 . The application rate was 150 L ha -1 . Surface tension was measured by the pendant droplet method. Contact angle was measured on the adaxial and abaxial surfaces of leaves of the pasture weed Senna obtusifolia and parafilm. Preparation sequence did not change the contact angle on any of the analyzed surfaces at a dose of 1 L ha -1 of herbicide. For the dose of 2 L ha -1 , the adjuvants SIL and LEC showed a higher spreading when previously added to the herbicide. MO resulted in a higher spreading when added after the herbicide, with higher surface coverage. Therefore, the preparation sequence influences the dispersion of phytosanitary spray solutions on targets.
Contributions to the development of microwave active circuits: metamaterial dual-band active filters and broadband differential low-noise amplifier

New telecommunication systems require electronic components with increasing performance. Microwave active circuits are not an exception. In fact, these active devices (such as amplifiers, active filters, oscillators, mixers, switches, modulators, etc.) are a key part of any modern communication device and, in many cases, the components that greatly limit the overall system performance. During the last decades, engineers have been improving the performance and operation capabilities of such active components, in order to satisfy the new requirements that novel communication services were demanding. This development has taken place in two distinct lines of action. The first line deals with the optimization of the fabrication process of the transistors, which are the basic components in most active circuits. This physical improvement usually translates into higher transconductance, lower noise gure or operation at higher frequencies. The other line is related with the circuit topology in which the transistor is embedded. This second aspect handles the interaction of the transistor with other additional components or transmission lines and provides the desired operation (e.g., amplification, oscillation, etc.). This thesis is more related with the last aspect, in which the use of novel active circuit topologies is investigated. Two main research lines are presented. In the first line, novel dual-band active filter topologies are proposed. This multiband response is achieved by the use of metamaterial structures. In the second one, the use of differential low noise amplifiers is proposed for the design of active antenna arrays. The intended application is the development of a broadband active antenna array demonstrator for radio-astronomy applications.
