Security of several AES Implementations against Delay Faults

parmi les attaques en faute, la DFA (Differential Fault Analysis) est celle qui est la plus etudiee, mais certains modeles de faute utilises sont consideres comme irrealistes (ex : l'inversion d'un seul bit par injection de faute). Des glitches sur l'alimentation, si ils induisent des delais sur l'ensemble du circuit, peuvent realiser ce modele de faute, ceci dependant du circuit attaque et de la precision du controle de la duree du glitch. Dans cet article, la sensibilite de quelques implementations materielles d'AES vis-a-vis des attaques en delai est analyse. Il est montre que certaines attaques DFA theoriques peuvent etre pratiquement montees sur les implementations les plus sensibles ; les concepteurs de circuits securises doivent donc choisir parmi toutes les implementations possibles celle qui correspond au meilleur rapport securite / performance
EVALUATION OF THE MECHANICAL AND INSULATION PROPERTIES OF A POLYMERIC COMPOSITE WITH CORN COB LOADS TRITURATED EVALUACIÓN DE LAS PROPIEDADES MECÁNICAS Y AISLAMIENTO DE COMPUESTO POLIMÉRICO CON CARGAS DE MAZORCA DE MAÍZ TRITURADAS

The objective of this work was to study the viability of the use of the crushed corn cob, employed as load in a composite polyester resin. The specimens were produced with 5, 10 and 20% by weight of the ground corn cob, as fine particles (FP), medium particles (MP) and large particles (LP) to investigate the influence of the loading content on the mechanical and thermal conductivity properties of the composite material. The results of the mechanical tests, the data of impact test presented a satisfactory result for all the composites. However, the photomicrographs of the composites through SEM indicated low mechanical load/matrix adhesion, with few signs of effective stress transfer between phases, noting that the most viable particle size is the fine particle (FP). The composites shown to be viable for thermal applications, with a thermal conductivity of 0.138 W/m lowe than 0.21 W/m, being classified as thermal insulation. Palabras clave: polyester resin, corn cob, modulus of elasticity, thermal conductivity, insulation.
A New Content-Based Image Retrieval Method Based on the Google Cloud Vision API

Content-based image retrieval (CBIR) methods analyze the content of an image, extract the features that describe images, and yield image annotations or labels. A machine learning (ML) algorithm is commonly used to acquire these annotations. The need to import a large number of training images and use of many CPU hours are the two primary difficulties of using existing ML algorithms. Google Cloud Vision application programming interface (API) might overcome these two shortcomings. Cloud Vision API is trained by Google; therefore, it saves computational time in obtaining image labels. We test whether this API can outperform existing ML algorithms in describing annotations. To the best of our knowledge, this paper is the first to illustrate the effectiveness of Cloud Vision API for image labeling. Our programs are coded in the R language, which calls Cloud Vision API. We retain at most ten labels—with scores over 50—for each image. Because there is a semantic gap between the labels returned by Cloud Vision API and the image datasets, we define a transformation method to map the terms. We selected a well-known dataset and 4972 figures, and we used them to compare Cloud Vision API with the corresponding image annotation algorithms. This work found that Cloud Vision API yields 42.4% correctness among the 4972 images. In each dataset, Cloud Vision API is more effective than the ML algorithms. This paper compares the CBIR performance of Google Cloud Vision API and some ML algorithms. According to the extensive experimental results, Cloud Vision API is quite competitive compared with other image annotation algorithms. Hence, this API could be extended to test other image datasets and be used as a benchmark method for Email addresses: shchen@csu.edu. tw (Shih-Hsin Chen), chenyh@asia.edu. tw (Yi-Hui Chen) Preprint submitted to Computer Vision and Image Understanding October 25, 2017 evaluating ML algorithm performance.
Effectiveness of computer-assisted argument mapping for comprehension, recall, and retention

Abstract Compared to traditional pen-and-paper presentation of information, computer-assisted argument mapping seems to be more efficient in developing lower order thinking skills such as memory and comprehension. The present study investigated the impact of argument map construction and reading via computer versus pen and paper on English as a foreign language (EFL) majors’ comprehension, recall, and retention of argumentative texts. To this end, 120 Iranian EFL undergraduates were divided into low and high proficiency levels after taking a language proficiency test. Next, they were randomly assigned to two experimental groups; each group received 12 sessions of argument mapping instruction, one via computer and the other via pen and paper. At the end of the term, participants randomly received two argument map sizes (small vs. large) and were given 15 minutes to read the maps. Then tests of recall and comprehension relevant to the maps were administered, followed by a test of retention within a two-week interval. The results revealed that after controlling for spatial and verbal covariates, the type of treatment had a significant effect on recall, retention, and comprehension, with the software group outperforming the pen-and-paper group; however, proficiency level and argument size did not show any significant effect.
Comparative study of the outcome of tubed versus tubeless percutaneous nephrolithotomy

Percutaneous nephrolithotom (PCNL) is the best choice in treating renal stones currently. The PCNL is followed by placement of nephrostomy tube and stent that help in tamponade of percutaneous tract. Tubeless PCNL is accompanied by less postoperative pain and shorter hospital stay. Despite advantages of tubeless PCNL, some surgeons still excluded bleeding or residual stone patients, no chance of second look which increase chance of missing residual stone fragments, requiring often an additional procedures like cystoscopy, stent dysuria and risk of no drainage for kidney. This study aimed to compare the effectiveness and safety of tubeless PCNL to tubed PCNL. Methods: A prospective comparative study conducted in Urology department of Safeer Al-Imam Al-Hussein in Karbala, from January 2013, 1st to December, 31th 2017. One thousand four hundreds thirty four patients with renal stones surgically operated with PCNL were categorized into two groups; 882 patients with renal stones were treated with tubed PCNL and 552 patients were treated with tubeless PCNL. Results: The young age female were predominantly related to tubeless PCNL. Left sided stones with lucent and upper approach were significantly associated with tubeless PCNL. The tubed PCNL was significantly related to right side stone, while tubeless PCNL was significantly related to left side stone (p = 0.006). Tubeless PCNL was significantly associated with lucent opacity more than tubed PCNL (p = 0.001). Postoperatively, tubeless PCNL was significantly associated with lower rates of residual stone (p = 0.005), bleeding (p = 0.04) and sepsis (p = 0.01) compared to tubed PCNL. Conclusion: The tubeless option is effective and safe modality for PCNL. The low rate of residual stones and postoperative bleeding and sepsis can safely have associated with Tubeless PCNL.
Susceptibility of Spodoptera littoralis ( Boisd . ) to treated entomopathogenic rhabdities , Heterorhabditis bacteriophora and Steinernema sp . by different pesticides

Spodoptera littoralis (Boisd.) is a major plant pest that causes substantial economic losses worldwide especially in vegetable crops. Entomopathogenic nematodes (EPNs) in the families Steinernematidae and Heterorhabditidae are generally considered beneficial organisms which can serve within integrated pest management (IPM) in agroecosystem. The effect of EPNs Steinernema sp. (EBN1e), and Heterorhabdities bacteriophora (EBN10k) that exposed to 11 different chemical pesticides on the cotton leafworm larvae was determined under laboratory condition. Generally, Steinernema sp. (EBN1e strain) exposed to different tested chemical pesticides was more affected on fifth instar larvae of S. littoralis than H. bacteriophora (EBN10k strain). More than 90% of fifth instar larvae of S. littoralis was killed after exposure to EBN1e strain treated with all used chemical pesticides except EPN1e strain treated with chlorfluazuron, thiocyclam and benomyl which caused 75.45, 80.65 and 81.5 % mortality of cotton leafworm fifth larvae respectively. In otherness, the mortality of fifth instar larvae of S. littoralis required to Heterorahbdities strain was less than Steinernema strain treated with different tested chemicals insecticides. There were significant differences in mortality of S. littoralis fifth instar larvae between EBN1e and EBN10k nematodes strains exposed to different chemical insecticides. The EBN1e strain was highly virulent than EBN10k in all treatments. In general, there was significant difference in mortality rates of cotton leafworm larvae required to EPNs concentrations (500IJs and 1000IJs) exposed to different chemicals and between exposure times.

Work Accommodations in Canadian Social Firms: Supervisors’ and Workers’ Perspectives

Social firms (SFs) are an appealing model for people with a mental health condition who are having difficulties maintaining their employment in a competitive labour market. The goal of this study is to compare the availability of work accommodations in two types of Canadian SFs, by interviewing supervisors working in adapted enterprises and consumer/survivor-run businesses, and by obtaining the perceptions of the workers with a mental health condition regarding the usefulness of these accommodations. Results indicate accommodations in both types of SFs are readily available and useful. A significant difference between the two types of SFs is the availability of a job coach whose presence workers found useful in adapted enterprises. Natural supports from stakeholders (e.g., supervisors, job coach) are important for work sustainability.

Tax Competition With Asymmetric Endowments in Fossil Resources

This paper contributes to the theoretical understanding of strategic interactions of governments on global factor markets. We analyze carbon taxes and subsidies and their impact on national welfare in a two country model with markets for capital and fossil resources, and asymmetric resource en- dowments. We have four contributions. First, we show that resource poor countries have an incentive to tax the use of fossil fuels to appropriate the resource rent. Resource rich countries subsidize fossil fuel use to attract production factors in order to increase national income. Second, we demonstrate that capital mobility has a taming effect on the incentives to tax and to subsidize resources. When taxing resources not only affects the international resource market, but also the international capital market, taxation is more distortionary and is thus more costly to governments. Third, while early studies of asymmetric tax competition found that small countries in terms of population are winners of tax competition, we show that with asymmetric resource endowments but a symmetric population size, there are no winners. Then, the Nash equilibrium of carbon tax competition is the least desirable outcome in terms of social welfare. A game structure similar to a Prisoner’s Dilemma emerges and cooperation makes Pareto improvements over the Nash equilibrium possible. Fourth, we explore the distinction of strategic policy interaction in tax competition and tariff war.
Learning Non-Adjacent Dependencies: A Mechanism for Language Acquisition

This dissertation explores the human ability for non-adjacent dependency-learning, which allows adults and infants to detect the relationship between a and b in an aXb string. I use artificial grammar learning with adults and infants to investigate whether non-adjacent dependency-learning could facilitate the detection of morpho-syntactic dependencies in natural languages (The princess is gently kissing the frog). Morpho-syntactic dependencies are typically instantiated between functional morphemes (is, -ing), straddling lexical morphemes (gently, kiss). Functional morphemes are often less prosodically prominent than lexical ones. I investigate the role that this prosodic contrast could play in non-adjacent dependency-learning: both adults and infants learn aXb dependencies when a/b are prosodically prominent, but also when they are prosodically weak compared to the intervening X, similar to functional morphemes straddling a lexical word. The prosodic properties of natural languages could thus facilitate non-adjacent dependency learning. Secondly, children seem to become familiar with the individual units of a morpho-syntactic dependency beforree learning the dependency itself. I investigate how prior familiarity with a/b impacts learning aXb dependencies for adults. Previous findings suggest a negative effect of prior familiarity with a/b, but I find that these results are based on a confound relating to the sequential presentation of two learning phases (learning a/bs, and learning aXb dependencies). Eliminating this confound, I find no significant disadvantage of prior familiarity with a/b. Finally, I show that adults can generalize a_b dependencies to novel aX’b strings (with unfamiliar X’), but, 18-month-olds show no such generalization. Young learners may only be able to track dependencies in familiar contexts.
The role of energy in a real-business-cycle model with an endogenous capital utilization rate and a government sector: lessons from Bulgaria (1999-2016)

We introduce a pro-cyclical endogenous utilization rate of physical capita1 stock into a real-business-cycle model augmented with a detailed government sector. We calibrate the model to Bulgarian data for the period following the introduction of the currency board arrangement (1999-2016). We investigate the quantitative importance of the endogenous depreciation rate, and the capital utilization mechanism working through the use of energy for cyclical fluctuations in Bulgaria. In particular, a positive shock to energy prices in the model works like a negative technological shock. Allowing for variations in factor utilization and the presence of energy as a factor of production improves the model performance against data, and in addition this extended setup dominates the standard RBC model framework with constant depreciation and a fixed utilization rate of physical capital, e.g., Vasilev (2009).
Erratum Aerodynamics of Scaled Runback Ice Accretions

Runback ice accretions present a unique situation in iced-airfoil aerodynamics in that the airfoil typically has a clean leading edge before the ice accretion. To investigate the aerodynamic effects of runback ice accretions, simulations were scaled from accretions obtained in theNASAGlenn IcingResearchTunnel for testing in the Illinois subsonic wind tunnel. Simple geometric scaling, based on airfoil chord, as well as boundary-layer scaling, based on estimated boundary-layer thickness, was used. The NACA 3415 and the NACA 23012 airfoils were tested at a Reynolds number of 1:8 10 andMach number of 0.18. Simple two-dimensional simulations were tested as well as three-dimensional simulations that more accurately simulated the features of the full-scale ice accretion. Significant aerodynamic penalties due to runback accretions were identified. In the worst case these penalties included a loss of over 0.75 in Clmax and 7 deg in stalling angle of attack. In certain cases scaled runback accretions were found to increase the stalling angle of attack and maximum-lift coefficient. This phenomenon was investigated using boundary-layer measurements and fluorescent-oil flow visualization. It was concluded that the interaction between the boundary layer and the simulation was responsible for the phenomenon.
An overview of the micrometeorological field campaign at Santa Maria, Southern Brazil: the Pampa‐2016 experiment

The Pampa‐2016 experimental campaign was performed in a typical Pampa lowland South American region. It consisted of both surface flux measurements (at 3 and 29 m) and a radiosonde launched every 3 h. The resulting meteorological observations allowed for the analysis of turbulent properties associated with both a stable and a convective boundary layer. The combined analysis of the surface data and vertical soundings has revealed some general characteristics of the atmospheric boundary layer for both the nocturnal stable conditions and the daytime convective environment. The continuous surface measurements showed that the nocturnal stable inversion, occurring in calm winds, is basically generated by the radiative cooling mechanism that is established after the late afternoon transition. The analysis of night‐time surface data also showed that, under stable conditions in the case of vanishing wind speed, the friction velocity has unrealistic values that are very close to zero. This situation is undesirable for numerical models that generally use this quantity as a lower boundary condition. The analysis of night‐time temperature profiles revealed two contrasting patterns in agreement with the classical classification of radiative night (a very stable boundary layer) and a turbulent night (a weakly stable boundary layer). In contrast, the analysis of the daytime temperature profiles provided an estimation of the convective time scale that is of the order of 10 min, in agreement with experimental values. A spectral analysis and the consequent estimation of the spectral peaks under unstable and stable conditions were in agreement with literature values.
J . P . 1 . 22 SIMULATIONS AND MEASUREMENTS OF RADAR REFLECTIONS FROM THE MELTING LAYER OF PRECIPITATION AT MM WAVELENGTHS

The melting layer of precipitation is the layer below the 0oC isotherm where snowflakes melt and turn into raindrops. This layer is commonly known as the ‘radar bright band’ because it often appears as a band of enhanced reflectivity when viewed through radar operating at cm or mm wavelengths. The microphysics of the melting layer of precipitation as well as its interaction with electromagnetic waves are important both in climate studies and in telecommunications: on the one hand, the melting layer is a characteristic feature of stratiform precipitation; on the other hand, this layer has a degrading effect on satellite communication links. In this study we present simulations and measurements of radar reflections from the melting layer of precipitation. Our objective is the validation of a theoretical model of backscattering of EM waves from the melting layer of precipitation. The theoretical model is briefly described in Section 2; it combines a simple microphysical model of the melting layer of precipitation [1] with a T-matrix technique for calculating the scattering of EM waves by partially aligned axially symmetric particles [2,3]. The radar observations are presented in Section 3; they were made during the Baltex/Bridge Cloud campaign [4] by use of an atmospheric radar with Doppler and polarimetric capabilities [5]. Comparisons between simulations and measurements are presented and discussed in Section 4. Finally, concluding remarks and suggestions for future work are made in Section 5.
PART Avenues for Improving Strategy and Policy in the Food System: Emerging Issues

following: (1) How are food safety priorities set by industry? (2) What pathogens should be controlled? (3) How are costs/benefits of food safety calculated? (4) Do we have too many or too little micro-contaminants in our food now? (5) Where should food safety data, specifically micro data, come from: industry, government, or academia? (6) What are the roles of industry, government, and academia in food safety research? The following remarks are prepared in an attempt to address these questions.
Intergenerational transfers in an aging economy trapped in secular stagnation

We characterize the dynamics of secular stagnation as a permanent regime switching from a full employment equilibrium to an underemployment equilibrium. In the latter, the natural interest rate is negative, and the economy is in deflation. Due to the non negativity condition imposed on policy rate, the zero lower bond (ZLB) applies which prevents targeting inflation. The secular stagnation equilibrium is achieved in a standard overlapping generations model with capital accumulation where two market imperfections are introduced: credit rationing and downward nominal wage rigidity. We then show that an aging population can bring the economy back into secular stagnation. To figure out how to escape the secular stagnation trap, we study the impact of transfers from workers to retirees. By lowering savings incentives, they can help the economy get out of the secular stagnation trap. In addition, they can be Pareto improving even if their return, the population growth rate, is lower than the savings return, the interest rate.
