Autonomous void detection and characterisation in point clouds and triangular meshes

In this paper we propose and demonstrate a novel void characterisation algorithm which is able to distinguish between internal and external voids that are present in point clouds of both manifold and non-manifold objects and 3D scenes. We demonstrate the capabilities of our algorithm using several point clouds representing both scenes and objects. Our algorithm is shown in both a descriptive overview format as well as pseudocode. We also compare a variety of different void detection algorithms and then present a novel refinement to the best performing of these algorithms. Our refinement allows for voids in point clouds to be detected more efficiently, with fewer false positives and with over an order of magnitude improvement in terms of run time. We show our run time performance and compare it to results obtained using alternative algorithms, when tested using popular single board computers. This comparison is important as our work is intended for online robotics applications, where hardware is typically of low computational power. The target application for this work is 3D scene reconstruction to aid in the decommissioning of nuclear facilities.
Effect of grape seed extract as a sunscreen booster

Grape seed extract (GSE) contains a high content of polyphenols that prevent the generation of reactive oxygen species which suggests an anti-aging action. The aims of this study were to investigate the antioxidant effects of GSE, ultraviolet (UV) and visible spectrums, and in vitro sunscreen efficacy. The results showed that GSE possessed DPPH free radical scavenging capacity at an IC50 of 33.17±1.87 μg/mL and ferric reducing power of 1 mg/mL. GSE was equivalent to 4.17±0.23 mM vitamin C and 0.73±0.04 mM Trolox. Moreover, 3% and 5% w/w GSE absorbed broad UV and blue light spectra to a sufficient extent. The sun protection factor (SPF) and persistent pigment darkening (PPD) increased to 5 units and 1 unit, respectively, after addition of 3% GSE to an over-the-counter brand product. In conclusion, GSE possessed antioxidant activity and boosted the SPF/PPD value of sunscreen product. Therefore, GSE can be a value-added component to sunscreen products.
Benefits , Justification and Implementation Planning of Real-Time Business Intelligence Systems

While traditional Business Intelligence (BI) environments have for some time assisted organizations with their information requirements, they have become increasingly incompatible with the pressures of current business environments. They are geared towards analysis of historical information, and limited in their ability to close the latency gap between information and action. This has encouraged a movement towards real-time BI (RTBI) systems. Although these overcome latency aspects of traditional BI, and offer many value-adding benefits to organizations, their implementation has been hampered by technological complexities, and has required changes to the business environment, and high costs to put them in place. Justification of such IT investments remains a problem as they provide many intangible benefits incompatible with traditional (financial) IT benefits measurement models. For these reasons, the research set out to investigate and understand the technological components and organizational changes surrounding RTBI implementation. To further facilitate justification, application areas and benefits of RTBI were also explored. Data was collected through semi-structured in-depth interviews in organizations across several industries that had implemented or were implementing RTBI systems. A qualitative thematic analysis was then used to investigate the issues further. The study confirmed that RTBI is likely to require major changes to technical architecture, which may involve acquisition of new tools and technologies. Several issues at the organisational level also need to be addressed, and the research uncovered a wide range of practical RTBI applications and analytics applied across industries; process intelligence was found to play a fundamental role in many of these. The study reveals that RTBI can offer significant and measurable improvements, help organizations remain competitive, and in the long run, drive strategic business objectives from a grass roots level. To assist organisations to take advantage of this, a roadmap for RTBI justification and implementation planning is suggested.
Rue de la Banque What policy to reduce labour market segmentation ?

The French labour market is segmented between those with stable jobs and those alternating temporary contracts and periods of unemployment. This Rue de la Banque looks at the different policies aimed at reducing this duality. It shows that contributions that decrease in line with seniority or a tax on contract terminations reduce the share of short‐term contracts in the economy, but at the cost of a more rigid labour market and lower productivity. An over‐contribution on temporary jobs, financing a premium for hiring on permanent contracts, also reduces the segmentation of the labour market; however, it does not have these adverse effects on labour market flexibility and productivity. Introducing a premium to reduce segmentation is therefore more desirable than a tax in order to preserve the flexibility of the labour market. Clémence Berson Banque de France
miR-27 b-3 p suppresses cell proliferation , migration and invasion by targeting LIMK 1 in colorectal cancer

Accumulating evidence has indicated that microRNAs (miRNAs) can act as candidate tumor suppressors. However, the mechanism of miR-27b-3p in colorectal cancer (CRC) is still unknown. In this study, the relative expression levels of miR-27b-3p and LIMK1 were detected by quantitative real-time PCR (qRT-PCR) in CRC and adjacent normal tissues as well as in CRC cell lines. The proliferation, cell cycle and migratory and invasive abilities of SW620 cells were analyzed by CCK-8, flow cytometry, wound healing assays, and Transwell assays, respectively. The regulatory relationships between LIMK1 and miR-27b-3p were detected by qRT-PCR, luciferase reporter gene and Western blot assays. The results showed that the expression levels of miR-27b-3p were downregulated in CRC samples compared with those in adjacent nontumor tissues. Moreover, we found that miR-27b-3p suppressed CRC cell proliferation, cycle and migration and invasion. Additionally, there was an inverse correlation between LIMK1 expression and miR-27b-3p expression in CRC tissues. LIMK1 was identified as a direct target of miR-27b-3p. Our findings indicated that miR-27b-3p inhibited CRC cell proliferation, migration and invasion by targeting LIMK1.
Università degli Studi di Brescia-CeSCAm International Conference “ LIVING AND WALKING IN CITIES ” Vulnerable users ’ road safety Brescia , 13-14 June 2013 State of the Art on Urban Road Safety

Purpose: The objective of this study is to provide a comprehensive picture of the current situation on urban road safety and of the future challenges with focus on urban safety and mobility in Europe, especially of the vulnerable road users. Results: Although urban road fatalities are constantly decreasing in the EU, during the last years, their share on total fatalities remains significant and increasing. In addition, trends in road fatalities vary considerably among the different European regions. Evidence based road safety decision making is a key component for the improvement of road safety in urban areas. However, several challenges related to data and knowledge need to be dealt with, including the various technical, political and international cooperation barriers preventing the assessment of road safety measures and their prioritisation. Conclusions: In the complex urban environment, a number of difficult road safety choices persist in order to balance conflicting social needs and economical restraints, especially during the economic crisis period. Urban road safety should be integrated into urban mobility plans, equally with environment, energy and mobility concerns, within a long term and sustainable vision. Both authorities and citizens should be supported by reliable scientific evidence and make the necessary brave choices with focus on slower traffic and car traffic restriction. Key-words: road safety, urban mobility, road safety measures

These are improved variants of Standard PSO (SPSO), Discrete PSO (DPSO) and Quantum PSO (QPSO). A domain-shrinking technique is used to improve the results of these algorithms when optimizing the electromagnetic device of the TEAM22 benchmark problem.
“ Neo-homelessness ” and the Greek Crisis

> Abstract_ This policy review focuses on the impact of the financial crisis and austerity measures on housing exclusion and homelessness in Greece. Despite homeless persons having been recently recognized in legislation as a specific vulnerable social group, the Greek state has not put in place any supportive measures for homeless persons and also has not developed a prevention policy to safeguard its citizens who struggle with the impact of the crisis. A “new generation” of homeless has appeared in Greece; the profile of this ‘’new generation’’ of homeless is dif ferent to that of the “traditional” homeless of the country. The general impact of the crisis in Greece, especially on the most vulnerable groups, cannot yet be measured, but it is clear that new initiatives are required in order to promote the development of social solidarity in Greece.
An Efficient Contourlet-Transform-Based Algorithm for Video Enhancement

Since many activities of interest often occur in the dark environment, video enhancement has become increasingly important. In this paper, we focus on addressing two key issues for nighttime video enhancement: (1) we propose a contourlet-transform-based scheme to address the fusion problem of the same scene between daytime and night-time videos. (2) Based on this, for further improving the perceptual quality of the moving objects, we propose an improved framework for nighttime video enhancement which can eﬃciently recover the unreasonable enhancement results due to imperfect moving objects extraction. Experimental results show that the proposed algorithm can obviously improve the visual quality from conventional methods.
Elevated resource availability sufficient to turn opportunistic into virulent fish pathogens

There is mounting evidence that organic or inorganic enrichment of aquatic environments increases the risk of infectious diseases, with disease agents ranging from helminth parasites to fungal, bacterial, and viral pathogens. The causal link between microbial resource availability and disease risk is thought to be complex and, in the case of so-called ‘‘opportunistic pathogens,’’ to involve additional stressors that weaken host resistance (e.g., temperature shifts or oxygen deficiencies). In contrast to this perception, our experiment shows that the link between resource levels and infection of fish embryos can be very direct: increased resource availability can transform benign microbial communities into virulent ones. We find that embryos can be harmed before further stresses (e.g., oxygen depletion) weaken them, and treatment with antibiotics and fungicides cancels the detrimental effects. The changed characteristics of symbiotic microbial communities could simply reflect densitydependent relationships or be due to a transition in life-history strategy. Our findings demonstrate that simple microhabitat changes can be sufficient to turn ‘‘opportunistic’’ into virulent pathogens.
Is Social Media Changing the Awareness of Individuals?

Social media has provided a platform for fake news, which most individuals distribute without realizing that it is fake news. Fake news distribution hinges on individuals’ awareness of information. The current study aimed to examine information awareness and assimilation among users of social media. Based on the collective action theory, the study conducted an online survey comprising Facebook and Instagram users and analysed 143 datasets. The results implied that social media is responsible for influencing the awareness of individuals, which in turn allows for fake news to be easily distributed.
Predicting Coral Reef Regimes from Human and Natural Influences

We perform a multi-class prediction of coral reef regime types based on anthropogenic and environmental features. We use several models logistic regression, SVM, decision trees with different architectures and features and compare performance. We achieve a best cross-validation microaverage F1 score of 0.70, up from 0.60 in our baseline model. We complete error analysis and PCA to understand the limits of our models.
International Society for Environmental Information Sciences 2010 Annual Conference ( ISEIS ) Forecasting and Evaluating Water Quality of Chao Lake based on an Improved Decision Tree Method

As the water quality of Chao Lake becomes diverse and eutrophied, predicting and evaluating water quality become more and more important. But prediction and evaluation are complex problems. In this paper, we come up with an improved decision tree learning method making water quality prediction easier and forecast more accurate. The classification standards are based on the evaluation mechanisms provided by the Hong Kong Environment Protection Department. We released an online web forecast system to apply to the classification and prediction of Chao Lake. Experimental results show that the improved method is better than artificial neural network or genetic algorithm with higher recognition rate and forecast accuracy and strong practical value. © 2010 Published by Elsevier Ltd.

Mundane metaverses : communicating by voice in virtual worlds

Users of online virtual worlds such as MUDs and MMORPGs have traditionally communicated by typing text messages. Recently voice-over-IP (VoIP) has become a popular alternative to text communication. We are interested in how VoIP changes the experience of virtual worlds. This paper discusses research into how people are using VoIP in online worlds. It is argued that some of the problems of voice communication arise because VoIP channels disrupt the boundary between a virtual world and its users’ real-world settings.
A critical review on feature selection techniques in software defect prediction

Software has turn into an imperative part of human’s life, so building defect free software is a must. It is necessary to predict defect-prone software modules prior to deployment of software project in order to plan exceptional maintenance approach. Early observation of defect prone software module can further support to make adequate process improvement plan within justified period of time and cost. This can further lead to improved software release as well as immense customer satisfaction subsequently. Accurate measurement and prediction of defect is a crucial issue in any software because it is an indirect measurement and is based on several attributes. Therefore, instead of considering all the attributes, it would be more useful to find out a suitable set of attributes which are relevant and significant for defect prediction in any software modules. Feature selection and feature extraction techniques are used to determine the significant attributes set which are undoubtedly affecting the defect prediction in software modules. The efficiency of prediction models could be enhanced with reduced 1 International Journal of Pure and Applied Mathematics Volume 114 No. 5 2017, 43-53 ISSN: 1311-8080 (printed version); ISSN: 1314-3395 (on-line version) url: http://www.ijpam.eu Special Issue ijpam.eu
TAS according metal appliances in patients with chronic periodontal disease

Introduction Periodontal status is believed to have a significant influence on general health in man [6]. During the periodontal disease teeth movement and lost of them is present, as a result of chronic inflammation. It's important in periodontal treatment to reduce this process and restore the function and esthetics of occlusion. Orthodontic and prosthetic therapy which are necessary, are connected with using some metal appliances. Coexisting different metal elements in oral cavity environment could be the reason of galvanic battery and tissue injury. It has been documented in vitro and in vivo that metal dental appliances release metal ions due to corrosion. Dentists must choose among many dental casting alloys available, often without knowledge of their biological properties and effect on oral mucosa [1]. Divalent metal ions like iron (Fe), zinc (Zn),manganese (Mn),copper (Cu) and cobalt (Co) are essential cofactors in a number of biological processes, including oxidative phosphorylation, gene regulation and free-radical homeostasis. There is an increasing evidence that nutrition can modulate the kinetics and toxicity of heavy metals and thus modulate health and disease outcomes associated with exposure to such elements [9]. Divalent metal ions iron (Fe), zinc (Zn),manganese (Mn), copper (Cu) and cobalt (Co) are essential cofactors in a number of biological processes, including oxiThe periodontal status of 34 patients with chronic periodontitis, aged 32 to 60 years was evaluated. Analyses of acute phase proteins and the total antioxidant status (TAS) in correlation with metal were performed by the Laurell and Randox tests. The results suggest that the metal presence is significant factor in status of periodontal disease. AGP and ACT concentrations were highest for group with just filling, whereas crowns or dentures did not show elevated acute phase proteins concentrations. TAS level increased with the amount of metal present, whereas ochratoxin A concentration was not affected by metal at all.

How Much is a Green Card Worth ? Evidence from Mexican and Puerto Rican Men Who Marry Women Born in the U . S .

Recognizing that U.S. immigrants can acquire Permanent Resident status by marrying natives, we quantify the value of that status using the earnings premium received by Mexican-born men who marry U.S.-born women. Men born in Puerto Rico are a natural control group because they are U.S. citizens, but otherwise face similar challenges. IV estimates indicate that intermarried Mexicans earn a 30 percent premium, while intermarried Puerto Ricans receive no premium. The premium vanishes within ten years after immigration, consistent with waiting times for green cards. However, among Mexicans who immigrated less than six years ago, the estimated premium exceeds 100 percent. JEL Classification: J61, J12
Environmentally Conscious Optimization of Closed Loop Supply Chain Network with Vehicle Routing

Product recovery and remanufacturing have become important business strategies to gain a competitive edge in business and also in the society. Parts from discarded products due to rapid technological advancement and postconsumer products before & after end-of-life (EOL) are recovered to reduce landfill waste and to have some economic advantage. Along with the forward supply chain, manufacturers concentrate on the reverse supply chain, bringing light to the importance of Close Loop Supply Chain (CLSC) network. Product recovery is made possible with the help of CLSC. This paper concentrates on multi-period, multi-product, and multi-echelon Closed Loop Green Supply Chain (CLGSC) network. A bi-objective (cost and emission) Mixed Integer Linear Programming (MILP) model has been formulated for the network and has been optimized using Goal Programming approach. Results are discussed and sensitivity analysis is carried out to show some managerial insights of the model.
Verifying Large Multipliers by Combining SAT and Computer Algebra

We combine SAT and computer algebra to substantially improve the most effective approach for automatically verifying integer multipliers. In our approach complex final stage adders are detected and replaced by simple adders. These simplified multipliers are verified by computer algebra techniques and correctness of the replacement step by SAT solvers. Our new dedicated reduction engine relies on a Gröbner basis theory for coefficient rings which in contrast to previous work no longer are required to be fields. Modular reasoning allows us to verify not only large unsigned and signed multipliers much more efficiently but also truncated multipliers. We are further able to generate and check proofs an order of magnitude faster than in our previous work, relative to verification time, while other competing approaches do not provide certificates.
