Blood supply chain management: robust optimization, disruption risk, and blood group compatibility (a real life case)
Venue: J. Ambient Intell. Humaniz. Comput.
Year: 2020

Based on the uncertain conditions such as uncertainty in blood demand and facility disruptions, and also, due to the uncertain nature of blood products such as perishable lifetime, distinct blood groups, and ABO Rh(D) compatibility and priority rules among these groups, this paper aims to contribute blood supply chains under uncertainty. In this respect, this paper develops a bi objective two stage stochastic programming model for managing a red blood cells supply chain that observes above mentioned issues. This model determines the optimum location allocation and inventory management decisions and aims to minimize the total cost of the supply chain includes fixed costs, operating costs, inventory holding costs, wastage costs, and transportation costs along with minimizing the substitution levels to provide safer blood transfusion services. To handle the uncertainty of the blood supply chain environment, a robust optimization approach is devised to tackle the uncertainty of parameters, and the TH method is utilized to make the bi objective model solvable. Then, a real case study of Mashhad city, in Iran, is implemented to demonstrate the model practicality as well as its solution approaches, and finally, the computational results are presented and discussed. Further, the impacts of the different parameters on the results are analyzed which help the decision makers to select the value of the parameters more accurately.
Learning Siamese Network with Top Down Modulation for Visual Tracking
Venue: IScIDE
Year: 2018

The performance of visual object tracking depends largely on the target appearance model. Benefited from the success of CNN in feature extraction, recent studies have paid much attention to CNN representation learning and feature fusion model. However, the existing feature fusion models ignore the relation between the features of different layers. In this paper, we propose a deep feature fusion model based on the siamese network by considering the connection between feature maps of CNN. To tackle the limitation of different feature map sizes in CNN, we propose to fuse different resolution feature maps by introducing de convolutional layers in the offline training stage. Specifically, a top down modulation is adopted for feature fusion. In the tracking stage, a simple matching operation between the fused feature of the examplar and search region is conducted with the learned model, which can maintain the real time tracking speed. Experimental results show that, the proposed method obtains favorable tracking accuracy against the state of the art trackers with a real time tracking speed.
Parallel lives? working class Muslim and non Muslim women at university
Year: 2007

This thesis seeks to explore how experiences of class are mediated by positions of faith and ethnicity. Currently in the UK, class is gaining increased attention within the disciplines of sociology and women's studies. However, faith and ethnicity have been absent from these debates and the vast majority of qualitative studies on class have focussed on white British people, with the experiences of minority ethnic/religious groups largely ignored. In order to move debates on class and its intersections forward, this thesis critically analyses class identity in a comparative perspective as experienced by Muslim and non Muslim women. Based on interviews and a focus group with 18 Muslim and 11 non Muslim women, I interrogate the way in which positions of faith and ethnicity influence class experiences and identity for northern women from working class backgrounds at university. Using feminist engagement with a Bourdieusian theoretical framework, I discuss the similar and different experiences of class for the two groups of women, concentrating on themes of individual, family and community. Using concepts of class capitals and habitus, I analyse the decisions made about higher education (including course, institution and residential status) and experiences of university, centring on `fitting in' to `university life' and the balance between studying and employment. Analysing plans for the future, I focus on residential status, career and partnership, and I also explore the women's accounts of class mobility in relation to notions of past, present and future. The central difference between the two groups of women is that the non Muslim women saw education as a way to `escape' their working class lives and localities, whereas university for the Muslim women was a strategy for upward mobility for families as a whole.
Development and Testing of a Submerged Buoy Wave Power System
Year: 2006

This paper summarizes activity to date and discusses future activity in the NAF development. The combination of numerical computations, model testing in the U.C. Berkeley ship model testing facility, and 5kW prototype testing at sea led to some encouraging findings about the NAF response to real wave conditions, but also demonstrated deficiencies in our original thoughts for a power take off system for the NAF. A combination of numerical computations, model testing in the controlled environment of a tow tank, and scale prototype testing at sea led to some encouraging findings about a wave energy conversion devise coined the "NAF" but also demonstrated deficiencies in the propeller generator power take off approach. The experience led to a new approach to power take off where all the mechanical to electrical power generation equipment are to be housed inside the NAF body and an exterior shape that results in lower drag and less impact ocean sea life. EARLY DEVELOPMENT Since 2000, AeroVironment Inc. has been leading research and development into the NAF for ocean wave power generation (MacCready, Zambrano and Hibbs, 2003) Devices have been tested in the laboratory and at sea  and numerical analyses have been refined in its' response to true wave conditions, particularly for Gulf of Mexico metocean conditions.
A Multi Dimensional Framework for the Development of Authentic Consumer Products
Year: 2018

A common assumption in product value literature is that authenticity is what contemporary consumers value the most. However, as this paper illustrates, the meaning of authenticity is unclear, and the term appears foreign to product development practitioners. The purpose of this paper is to explore in what ways product development professionals talk about product value in general and how this relates to authenticity. The analysis of the interviews reveals that product developers must embrace authenticity as a holistic framework if the phenomenon is to be constructive for companies within the product development industry. In line with the concept of authenticity as a multi dimensional framework, this paper suggests that authenticity does not solely result from certain intrinsic tangible or intangible product characteristics, and that commercially strong products and brands do not automatically become "authentic".The contribution of this paper to the product development field is a framework for a multi dimensional construct of authenticity, and an account of what representatives within selected companies talk about when asked about how they create consumer value, and how they contribute to valuable consumer experiences. The findings are analysed and discussed in the context of literature on product development, brand management and marketing management.

Discovery without a 'logic' would be a miracle
Venue: Synthese
Year: 2015

Scientists routinely solve the problem of supplementing one's store of variables with new theoretical posits that can explain the previously inexplicable. The banality of success at this task obscures a remarkable fact. Generating hypotheses that contain novel variables and accurately project over a limited amount of additional data is so difficult the space of possibilities so vast that succeeding through guesswork is overwhelmingly unlikely despite a very large number of attempts. And yet scientists do generate hypotheses of this sort in very few tries. I argue that this poses a dilemma: either the long history of scientific success is a miracle, or there exists at least one method or algorithm for generating novel hypotheses with at least limited projectibility on the basis of what's available to the scientist at a time, namely a set of observations, the history of past conjectures, and some prior theoretical commitments. In other words, either ordinary scientific success is miraculous or there exists a logic of discovery at the heart of actual scientific method.
Factors Affecting Construction Labor Productivity in Kuwait
Year: 2012

AbstractConstruction labor productivity has become such a buzz word and one of the most frequently researched topics. In most countries, labor cost comprises 30 to 50% of the overall project's cost, and thus is regarded as a true reflection of the economic success of the operation. There are many challenges facing the construction industry in the state of Kuwait but one of the most important is low productivity. The objective of this research, therefore, is to identify and rank the relative importance of factors perceived to affect labor productivity on construction sites in Kuwait. To achieve this objective, a statistically representative sample of contractors was invited to participate in a structured questionnaire survey, comprising 45 productivity factors, classified under the following four primary groups: (1) management; (2) technological; (3) human/labor; and (4) external. Among the factors explored, the subsequent 10 are discerned to be the most significant in their effects on labor productivity:
TPC H Analyzed: Hidden Messages and Lessons Learned from an Influential Benchmark
Venue: TPCTC
Year: 2013

The TPC D benchmark was developed almost 20 years ago, and even though its current existence as TPC H could be considered superseded by TPC DS, one can still learn from it. We focus on the technical level, summarizing the challenges posed by the TPC H workload as we now understand them, which we call "choke points" We identify 28 different such choke points, grouped into six categories: Aggregation Performance, Join Performance,  On the meta level, we make the point that the rich set of choke points found in TPC H sets an example on how to design future DBMS benchmarks.
Broadcasting and Narrowcasting: How Audience Size Affects What People Share
Year: 2013

Does the number of people with whom someone communicates influence what he or she discusses and shares? Six studies demonstrate that compared with narrowcasting (i.e. communicating with just one person) broadcasting (i.e. communicating with multiple people) leads consumers to avoid sharing content that makes them look bad. Narrowcasting, however, encourages people to share content that is useful to the message recipient. These effects are driven by communicators' focus of attention. People naturally tend to focus on the self, but communicating with just one person heightens other focus, which leads communicators to share less self presenting content and more useful content. These findings shed light on the drivers of word of mouth and provide insight into when the communication sender (vs. receiver) plays a relatively larger role in what people share.
Quantifying the strength and form of sexual selection on men's traits
Year: 2013

Although recent research has increasingly focused on human sexual selection, fundamental questions remain concerning the relative influence of individual traits on success in competition for mates and the mechanisms, form, and direction of these sexual selective pressures. Here, we explore sexual selection on men's traits by ascertaining men's dominance and attractiveness from male and female acquaintances. On a large American university campus, 63 men from two social fraternities provided anthropometric measurements, facial photographs, voice recordings, and reported mating success (number of sexual partners) These men also assessed each other's dominance, and 72 women from two socially affiliated sororities assessed the men's attractiveness. We measured facial masculinity from inter landmark distances and vocal masculinity from acoustic parameters. We additionally obtained facial and vocal attractiveness and dominance ratings from unfamiliar observers. Results indicate that dominance and the traits associated with it predict men's mating success, but attractiveness and the traits associated with it do not. These findings point to the salience of contest competition on men's mating success in this population.
Real time Virtual Collaborative Environment Designed for Risk Management Training: Communication and Decision Making. (Environnement virtuel multi joueurs temps reel pour la formation a la gestion des risques: Communication et prise de decision)
Year: 2017

Communication and Decision Making in a real time Virtual Collaborative Environment Designed for Risk Management Training Many accidents in transport, industry or healthcare result from a causal chain of events where inadvertent human errors have not been corrected in time. In such socio technical and dynamic systems where complexity and unpredictability widespread, training teams to risk management in real life like situations is crucial. This thesis aims to provide a virtual multi player environment designed for inter professional team training to risk management. To that end, a method to design risk management interactive and controlled scenario has been described. A communication system, a group decision making system and a team tracing model have been created. They all together enable the virtual team to be free enough to manage the educational situations. These coherent and innovative environment allows us to control the team activity and automate the edition of a personalized, individual and corporate debriefing at the end of a team training session.
Tracking exposure to child poverty during the first 10 years of life in a Quebec birth cohort.
Venue: Canadian journal of public health Revue canadienne de sante publique
Year: 2012

Early childhood poverty is associated with adult chronic diseases. The objectives of this study were to examine patterns of exposure to poverty during the first 10 years of life in the Quebec Longitudinal Study of Child Development (QLSCD) cohort according to three measures of poverty and to explore family characteristics associated with different poverty exposures.  Data from 1,334 participants from the QLSCD were collected annually at home from ages 5 months through 10 years. Household income (previous 12 months) and sources of income were recorded at each data round. Poverty status was operationalized as 1) living below the low income cut off of Statistics Canada, 2) receiving social welfare and 3) being in the lowest quintile of socio economic status. We plotted trends in the prevalence of child poverty over time. We used latent class growth modelling to identify subgroups with similar poverty trajectories. Duration of poverty according to each measure was computed separately for early childhood, middle childhood, and the entire 10 years of life.  Four trajectories of poverty were identified: stable poor, decreasing likelihood, increasing likelihood, and never poor. The three measures of poverty do not cover the same population, yet the characteristics of those identified as poor are similar. Children of non European, immigrant mothers were most likely to be poor, and there was a higher likelihood of children from single parent families to live in chronic poverty during the first 10 years.  A large proportion of children are exposed to poverty before 10 years of age. More effective public policies could reduce child poverty.
Struggles for a global Internet constitution: protecting global communication structures against surveillance measures
Venue: Global Constitutionalism
Year: 2016

In 2014, the UN Human Rights Committee published its Concluding Observations on the United States' fourth periodic report on the progress of the implementation of the International Covenant on Civil and Political Rights (UN Doc CCPR) in which also the US surveillance practices are criticised. The Committee's insistence on the right to privacy and its exterritorial effect is an important first step, but it is not comprehensive, as by remaining within the individual rights framework the UN Human Rights Committee fails to sufficiently take into account the systemic challenges in play. Developing a constitution of the Internet would necessitate not only protecting individual fundamental rights against state interference, but protecting communicative spheres by guaranteeing institutional autonomies and subjecting all social spheres to democratic control; this also requires opening up spaces for a critical public, including whistleblowers, and establishing a right to cryptography a crucial refraction in the polycentric panoptic schema.
Superconductivity in high pressure SiH4
Year: 2007

A combination of static and dynamical first principles electronic calculations of silane, SiH4, at high pressure has revealed a novel monoclinic structure with C2/c symmetry. This high pressure phase is metallic and composed of layers of SiH4 bridged by H bonds. Perturbative linear response calculations at 90 and 125 GPa predict large electron phonon couplings yielding an electron phonon coupling parameter l close to 0.9. The application of McMillan equation gives a superconducting critical temperature (Tc) between 45 and 55 K.
Improvement stability and performance of invertase via immobilization on to silanized and polymer brush grafted magnetic nanoparticles.
Venue: Food chemistry
Year: 2017

In this study, magnetic nanoparticles (Fe3O4) were modified sequentially with silica (Fe3O4@SiO2) glycidyl methacrylate (GMA) by surface initiated atom transfer radical polymerization (SI ATRP) and hexamethylene diamine (as a spacer arm) The p(GMA) grafted and SA modified form (i.e. Fe3O4@SiO2@pGMA SA 3) was used for covalent immobilization of invertase (EC 3.2.1.26) The amount of immobilized enzyme on Fe3O4@SiO2@p(GMA) and Fe3O4@SiO2@p(GMA) SA 3 was 36.1+ 0.9 and 33.4+ 1.3mg/g, respectively. The Km and Vmax values of immobilized invertase were found to be 39.4mmol/L and 349.5mmol/L min, and not significantly changed compared with free form (34.3mmol/L and 387.2mmol/Lmin) respectively, revealed that the applied protocol did not have any detrimental effect on the retained activity of immobilized invertase.
Speech Enhancement Using Bayesian Wavenet
Venue: INTERSPEECH
Year: 2017

In recent years, deep learning has achieved great success in speech enhancement. However, there are two major limitations regarding existing works. First, the Bayesian framework is not adopted in many such deep learning based algorithms. In particular, the prior distribution for speech in the Bayesian framework has been shown useful by regularizing the output to be in the speech space, and thus improving the performance. Second, the majority of the existing methods operate on the frequency domain of the noisy speech, such as spectrogram and its variations. The clean speech is then reconstructed using the approach of overlap add, which is limited by its inherent performance upper bound. This paper presents a Bayesian speech enhancement framework, called BaWN (Bayesian WaveNet) which directly operates on raw audio samples. It adopts the recently announced WaveNet, which is shown to be effective in modeling conditional distributions of speech samples while generating natural speech. Experiments show that BaWN is able to recover clean and natural speech.

Comparison of national strategies in France, Germany and Switzerland for DRR and cross border crisis management
Year: 2018

The ESPREssO project (funded by the European Union's Horizon 2020 research and innovation programme, under Grant Agreement No. 700342) prioritises the need for overcoming barriers to disaster risk reduction (DRR) in Europe, with cross border crisis management identified as one of its three central challenges. In this paper, we present a synthesis of the different legal, policy and scientific approaches to DRR in France, Germany and Switzerland, through work carried out for the ESPREssO project on the basis of stakeholder interviews and an analysis of legal and policy references. A comparison of these three differing DRR strategies is then carried out, focusing specifically on resulting impacts for cross border crisis management, capitalizing on lessons learned from the tri national border region Upper Rhine Valley to complete the analysis.
IoT based intelligent fitness system
Venue: J. Parallel Distributed Comput.
Year: 2018

With the global economic growth, fitness club is developing rapidly in the world. Meanwhile, the fitness industry is booming especially for urban white collar population. In the circumstances, people need more scientific and practical guidance to build their body. In this paper, we design an Internet of things (IoT) based fitness system to monitor the health statuses of exercisers. The system provides guidance for exercisers. When exercising, the exercise data is collected by sensors and fitness band. Subsequently, these data are sent to the system to be analyzed. With the help of artificial intelligence technology, the system can extract useful guidance information for users' body building. In this paper, we will describe the details of the system and further reach out to the implementation technologies. The design of this kind of system is a trend for the future fitness application.
