Mechatronic design of NAO humanoid

This article presents the mechatronic design of the autonomous humanoid robot called NAO that is built by the French company Aldebaran-Robotics. With its height of 0.57 m and its weight about 4.5 kg, this innovative robot is lightweight and compact. It distinguishes itself from existing humanoids thanks to its pelvis kinematics design, its proprietary actuation system based on brush DC motors, its electronic, computer and distributed software architectures. This robot has been designed to be affordable without sacrificing quality and performance. It is an open and easy-to-handle platform. The comprehensive and functional design is one of the reasons that helped select NAO to replace the AIBO quadrupeds in the 2008 RoboCup standard league.
Epidemiology of stroke in India

Several population-based surveys on stroke were conducted from different parts of India. During the last decade, the age-adjusted prevalence rate of stroke was between 250-350/100,000. Recent studies showed that the age-adjusted annual incidence rate was 105/100,000 in the urban community of Kolkata and 262/100,000 in a rural community of Bengal. The ratio of cerebral infarct to hemorrhage was 2.21. Hypertension was the most important risk factor. Stroke represented 1.2% of total deaths in India.
Stable Recovery with Analysis Decomposable Priors

In this paper, we investigate in a unified way the structural properties of solutions to inverse problems. These solutions are regularized by the generic class of semi-norms defined as a decomposable norm composed with a linear operator, the so-called analysis type decomposable prior. This encompasses several well-known analysis-type regularizations such as the discrete total variation (in any dimension), analysis group-Lasso or the nuclear norm. Our main results establish sufficient conditions under which uniqueness and stability to a bounded noise of the regularized solution are guaranteed. Along the way, we also provide a strong sufficient uniqueness result that is of independent interest and goes beyond the case of decomposable norms.
America and the Arab World through the prism of the United Nations : a study of Libya and Sudan in the post-Cold War era (1990-2006)

There exists a number of important key issues surrounding the drafting of the United Nations (UN) Charter and affecting relations between the United States (US) and the UN - not least of which have been the standards of the UN Charter and the extent to which the US has influenced international decision-making and exploited the UN Security Council in attempts to promote US foreign policy interests and achieve its own political agenda. I query the variables affecting the UN Security Council’s powers under the auspices of maintaining the international balance of power and raise questions surrounding how the US was able to expand its own foreign policy agenda, specifically toward Arab nations, under the umbrella of the UN. In addition, I examine how the US made efforts to push other UN members in directions that they might not have wanted to follow in specific cases in the Arab World, including those of the Palestinian-Israeli conflict, Iraq, Somalia, Libya and Sudan. The research illustrates a significant transformation in the tasks dealt with by the UN Security Council and its performance in the Arab World through the two case studies of Libya and Sudan. Primary data was collected through interviews with four administrators involved in Libyan and Sudanese foreign policy and the UN during the post-Cold War era (1990-2006). The findings reveal a positive correlation between the ability of the US to predominate over decision-making within the UN Security Council and to successfully influence its policies in order to achieve the collective legitimisation of its own actions and political agenda.

Jamming defense against a resource-replenishing adversary in multi-channel wireless systems

We revisit the jamming defense problem in a multi-channel wireless system, using a general formulation of online learning against an adversary via repeated game-playing. We provide the explicit form of the worst-case optimal channel-hopping strategy of a legitimate user in a multi-stage interaction with a resource-replenishing jamming attacker. Interestingly, we show that the worst imaginary enemy can be given as an adversary who behaves in an i.i. d. manner in this multi-stage interaction, and the optimal strategy of the user is determined by the induced random walk of the adversarial behavior. In addition to the jamming defense, our framework is also applicable to other competitive game problems with finite action spaces.
Improved pulse -width modulation of diode-assisted buck-boost voltage source inverter

This paper explorers modulation strategies for diode-assisted buck-boost voltage source inverter and the relationship of voltage transfer ratio versus modulation index. Two kinds of improved pulse-width modulation strategies with high dc link voltage utilization are presented to obtain maximum voltage gain at given modulation index and minimize the voltage stress at the same time. The operation principle and realization of the proposed modulation strategies, the relationship of voltage gain versus modulation index and voltage stress versus voltage gain are analyzed in details. Simulation results are given to verify the theoretical analysis and demonstrate good performance of the improved pulse width modulation strategies.
Analysis of the Unanticipated Factors in Portfolio Inflows to Indonesia: A SVAR Approach: 2001-2012

After the 2008 global economic crisis, as one of the emerging markets, Indonesia has experienced a lot of capital inflows. The increase in capital inflows has stimulated economic activities and caused macroec onomic fluctuations. This study focuses on the analysis of pull and push factors that affect the portfolio capital inflows to Indonesia. The study utilizes structural vector autoregressive (SVAR), impulse responses function (IRF), and variance decomposition (VD) methods. The method of SVAR is used to analyze the shocks to factors relatively affecting the variation of incoming portfolio inflows (equity and bond inflows) to Indonesia, as well as the responses of the portfolio inflows to shocks to these factors. The findings indicate that SVAR approach can be employed in this study. The results of the impulse responses functions show that the portfolio inflows in the form of bonds generate positive response to the unexpected changes of budget deficit and domestic output growth, while the portfolio inflows in the form of stocks generate positive response to the unexpected changes in foreign output growth, domestic output growth, stock price index, and budget deficit. Furthermore, the results of variance decomposition analysis indicate that domestic interest rate and current account balance are the main determinants that explained the variation of portfolio inflows in the form of bonds, while the domestic interest rate and stock price index are the most dominant variables that explained the variation of portfolio inflows in the form of stocks.
Generic Project Success and Project Management Success Criteria and Factors: Literature Review and Survey

This paper covers a thorough literature review on “Project Success” and “The Generic Project Success Criteria and Factors”. In recent times, it has become a common belief that project success is defined by meeting the time, cost and quality requirements of organizations. However, there are some important project success criteria (PSCs) and factors (PSFs) which often get neglected when it comes to evaluating a project. The results of a survey, conducted by the researchers, show that to the contrary of what is mentioned in the literature, “Top Management Support” turned out to be the most important measure of project success. “Time” and “Quality” and their process, on the other hand, were not considered as critical success criteria. In fact, a controversial discovery is that some so called project success factors could potentially be considered as criteria for evaluating projects. This paper suggests the necessity of further investigations on the discrepancy between theoretical project success criteria and factors and those considered important in industry. In fact, the paper’s authors believe that this controversy occurs because projects’ stakeholders have different definitions of project success. Moreover, the survey presents a balance between the numbers of respondents who believe that project success is deemed project management success and the respondents, who consider that this is not necessarily true.
Self-enrichment in globular clusters - I. An analytic approach

By means of analytical calculations, we explore the self-enrichment scenario for Globular Cluster formation. According to this scenario, an initial burst of star formation occurs inside the core radius of the initial gaseous distribution. The outward-propagating shock wave sweeps up a shell in which gravitational instabilities may arise, leading to the formation of a second, metal-enriched, population of stars. We find a minimum mass of the proto-globular cluster of the order of 10 6 M� . We also find that the observed spread in the magnitude-metallicity relation can be explained assuming cluster-to-cluster vari- ations of some parameters like the thermalization efficiency, the mixing efficiency and the Initial Mass Function, as well as variations of the external pressure.
Modeling Review Spam Using Temporal Patterns and Co-bursting Behaviors

Online reviews play a crucial role in helping consumers evaluate and compare products and services. However, review hosting sites are often targeted by opinion spamming. In recent years, many such sites have put a great deal of effort in building effective review filtering systems to detect fake reviews and to block malicious accounts. Thus, fraudsters or spammers now turn to compromise, purchase or even raise reputable accounts to write fake reviews. Based on the analysis of a real-life dataset from a review hosting site (this http URL), we discovered that reviewers' posting rates are bimodal and the transitions between different states can be utilized to differentiate spammers from genuine reviewers. Inspired by these findings, we propose a two-mode Labeled Hidden Markov Model to detect spammers. Experimental results show that our model significantly outperforms supervised learning using linguistic and behavioral features in identifying spammers. Furthermore, we found that when a product has a burst of reviews, many spammers are likely to be actively involved in writing reviews to the product as well as to many other products. We then propose a novel co-bursting network for detecting spammer groups. The co-bursting network enables us to produce more accurate spammer groups than the current state-of-the-art reviewer-product (co-reviewing) network.
1 Language and thought : Which side are you on , anyway ?

The debate over language and thought has traditionally been framed by two opposing stances: „universalist‟ and „relativist‟. The universalist view holds that language is shaped by universals of human cognition; on this view, languages make semantic distinctions drawn from a limited palette of universally available options – and when languages do differ semantically, those linguistic differences do not affect cognition. The relativist view in contrast, often attributed to Whorf (1956), holds that semantic distinctions are determined primarily by largely arbitrary linguistic convention, so that languages are free to vary widely – and that such linguistic differences do affect cognition. Thus, on the relativist view, rather than universals of thought shaping language, it is language that shapes thought, in a manner that varies with little constraint across languages.
A Synaptically Controlled, Associative Signal for Hebbian Plasticity in Hippocampal Neurons

The role of back-propagating dendritic action potentials in the induction of long-term potentiation (LTP) was investigated in CA1 neurons by means of dendritic patch recordings and simultaneous calcium imaging. Pairing of subthreshold excitatory postsynaptic potentials (EPSPs) with back-propagating action potentials resulted in an amplification of dendritic action potentials and evoked calcium influx near the site of synaptic input. This pairing also induced a robust LTP, which was reduced when EPSPs were paired with non-back-propagating action potentials or when stimuli were unpaired. Action potentials thus provide a synaptically controlled, associative signal to the dendrites for Hebbian modifications of synaptic strength.
Examining the Role of Behavioral Inhibition in Harsh Parenting Preferences: An Analog Study

EXAMINING THE ROLE OF BEHAVIORAL INHIBITION IN HARSH PARENTING PREFRENCES: AN ANALOG STUDY Kelsey T. Ellis Old Dominion University, 2018 Director: Dr. James F. Paulson Understanding the cognitive processes involved in harsh parenting behavior would have broad implications for parenting interventions and training programs. Few studies have addressed how parental stressors, specifically infant crying, can influence individuals’ selfregulatory cognitive capacities and ultimately their preference for harsh parenting strategies. Furthermore, little research has explored the link between these cognitive processes and harsh parenting preferences; thus, little work has been done to establish a true causal relationship. This study examined the role of behavioral inhibition in harsh parenting preferences when individuals were exposed to an infant crying noise. Participants (n = 129) were undergraduate students (Mage = 19.97 years; 79.8% female; 47.3% African American, 39.5% Caucasian) who were randomly assigned to one of two conditions: (1) white noise and (2) infant crying noise. During the experiment they completed a cognitive task to capture their behavioral inhibition as well as measures of emotion regulation, parenting attitudes/beliefs, and other predictors of harsh parenting. Hierarchical multiple regression analyses indicated that infant crying noise did not moderate the relationship between behavioral inhibition and harsh parenting preferences. However, as hypothesized, the analyses indicated that lower behavioral inhibition predicted harsher physical parenting preferences. In addition, gender differences in harsh parenting preferences were explored using analysis of covariance analyses, which indicated that males and females did not differ in harsh parenting preferences. However, the current study did not collect enough males to meet power criteria, which may explain this non-significant effect. Methodological implications and recommendations for future research are discussed.
High risk behaviour and fertility desires among heterosexual HIV-positive patients with a serodiscordant partner--two challenging issues.

AIM OF THE STUDY To evaluate fertility intentions and condom use among HIV-positive persons. METHODS Multicentre study based on anonymous data collection (questionnaire). RESULTS 114 questionnaires providing complete information were evaluated. 45% of HIV-positive women and 38% of HIV-positive men expressed the desire for children. Irrespective of this wish, half the study participants felt that health care providers would not sufficiently address their concerns regarding relationship, sexuality and fertility intentions. In HIV-discordant heterosexual couples, consistent condom use was mentioned by 73% of respondents. Among study participants no significant relationship between HAART, viral load and inconsistent condom use was found. In contrast, information on condom use obtained from the Swiss HIV Cohort Study (SHCS), where the information is obtained by interview, gave higher estimates (88%) of consistent condom use. CONCLUSIONS A significant proportion of HIV-infected individuals express a wish for parenthood. Issues related to fertility intentions and sexual relations need to be addressed more frequently by health care providers. Non-anonymous data collection on condom use may underestimate high risk behaviour.
Inelastic Electron Proton and gamma Proton Scattering, and the Structure of the Nucleon

A model for highly inelastic electron-nucleon scattering at high energies is studied and compared with existing data. This model envisages the proton to be composed of pointlike constituents (“partons”) from which the electron scatters incoherently. We propose that the model be tested by observing ϒ rays scattered inelastically in a similar way from the nucleon. The magnitude of this inelastic Compton-scattering cross section can be predicted from existing electron-scattering data, indicating that the experiment is feasible, but difficult, at presently available energies.
A Model Study of Oceanic Mechanisms Affecting Equatorial Pacific Sea Surface Temperature during the 1997–98 El Niño

In this study, the processes affecting sea surface temperature variability over the 1992-98 period, encompassing the very strong 1997-98 El Nino event, are analyzed. A tropical Pacific Ocean general circulation model, forced by a combination of weekly ERS1-2and TAO wind stresses, and climatological heat and freshwater fluxes, is first validated against observations. The model reproduces the main features of the tropical Pacific mean state, despite a weaker than observed thermal stratification, a 0.1 m s21 too strong (weak) South Equatorial Current (North Equatorial Countercurrent), and a slight underestimate of the Equatorial Undercurrent. Good agreement is found between the model dynamic height and TOPEX/Poseidon sea level variability, with correlation/rms differences of 0.80/4.7 cm on average in the 108N-108S band. The model sea surface temperature variability is a bit weak, but reproduces the main features of interannual variability during the 1992-98 period. The model compares well with the TAO current variability at the equator, with correlation/rms differences of 0.81/0.23 m s 21 for surface currents. The model therefore reproduces well the observed interannual variability, with wind stress as the only interannually varying forcing. This good agreement with observations provides confidence in the comprehensive three-dimensional circulation and thermal structure of the model. A close examination of mixed layer heat balance is thus undertaken, contrasting the mean seasonal cycle of the 1993-96 period and the 1997-98 El Nino. In the eastern Pacific, cooling by exchanges with the subsurface (vertical advection, mixing, and entrainment), the atmospheric forcing, and the eddies (mainly the tropical instability waves) are the three main contributors to the heat budget. In the central-western Pacific, the zonal advection by low-frequency currents becomes the main contributor. Westerly wind bursts (in December 1996 and March and June 1997) were found to play a decisive role in the onset of the 1997-98 El Nino. They contributed to the early warming in the eastern Pacific because the downwelling Kelvin waves that they excited diminished subsurface cooling there. But it is mainly through eastward advection of the warm pool that they generated temperature anomalies in the central Pacific. The end of El Nino can be linked to the large-scale easterly anomalies that developed in the western Pacific and spread eastward, from the end of 1997 onward. In the far-western Pacific, because of the shallower than normal thermocline, these easterlies cooled the SST by vertical processes. In the central Pacific, easterlies pushed the warm pool back to the west. In the east, they led to a shallower thermocline, which ultimately allowed subsurface cooling to resume and to quickly cool the surface layer.
NEURAL MODELS OF HEAD-DIRECTION CELLS

After a review of the purpose and biological background of Head Direction Cells, and existing models of them, we introduce an improved neural model that integrates visual flow information with the vestibular inputs found in earlier models. Simulation results using real video inputs are presented to explore and validate the new model, the evolutionary advantages for the proposed arrangement are noted, its utility for use in robot controllers is discussed, and suggestions are made for further work in this area.
Gift Exchange within a Firm: Evidence from a Field Experiment

We present results from a field experiment testing the gift-exchange hypothesis inside a tree-planting firm paying its workforce incentive contracts. Firm managers told a crew of tree planters they would receive a pay raise for one day as a result of a surplus not attribuable to past planting productivity. We compare planter productivity - the number of trees planted per day - on the day the gift was handed out with productivity on previous and subsequent days of planting on the same block, and thus under similar planting conditions. We find direct evidence that the gift had a significant and positive effect on daily planter productivity, controlling for planter-fixed effects, weather conditions and other random daily shocks. Moreover, reciprocity is the strongest when the relationship between planters and the firm is long term.
