Homotopy techniques for multiplication modulo triangular sets

International audienceWe study the cost of multiplication modulo triangular families of polynomials. Following previous work by Li et al. (2007), we propose an algorithm that relies on homotopy and fast evaluation-interpolation techniques. We obtain a quasi-linear time complexity for substantial families of examples, for which no such result was known before. Applications are given notably to additions of algebraic numbers in small characteristic

Rekomendasi Tindakan Koreksi Terhadap Penyimpangan Biaya Pembelian Material Konstruksi

. In delivering construction projects, is not uncommon that cost overrun occur due to variation on materials, equipments, labors, subcontractors, overhead, and general condition. Material contributes around half of the construction project, which make material management becomes an important element in project cost control. And in managing construction materials, purchasing has become major influence on material cost. Corrective actions on cost overrun can be used to overcome the cost variance due to poor material purchasing. This paper is aimed at identifying what causes of purchasing material cost variances and correctice action recommendation. Research method to identifying purchasing material cost variance and corrective action recommendation using questionnaire survey and interview distributed to high rise building projects. Analyze method using analytical hierarchy process (AHP) and Delphi method. The result show that corrective action recommendationon purchasing material cost overrun is preventif action (before process variance)

Relative vibrotactile spatial acuity of the torso

While tactile acuity for pressure has been extensively investigated, far less is known about acuity for vibrotactile stimulation. Vibrotactile acuity is important however, as such stimulation is used in many applications, including sensory substitution devices. We tested discrimination of vibrotactile stimulation from eccentric rotating mass motors with in-plane vibration. In 3 experiments, we tested gradually decreasing center-to-center (c/c) distances from 30 mm (experiment 1) to 13 mm (experiment 3). Observers judged whether a second vibrating stimulator (‘tactor’) was to the left or right or in the same place as a first one that came on 250 ms before the onset of the second (with a 50-ms inter-stimulus interval). The results show that while accuracy tends to decrease the closer the tactors are, discrimination accuracy is still well above chance for the smallest distance, which places the threshold for vibrotactile stimulation well below 13 mm, which is lower than recent estimates. The results cast new light on vibrotactile sensitivity and can furthermore be of use in the design of devices that convey information through vibrotactile stimulation.Peer Reviewe

Influence of Pasteurization on Total Phenols Content and Antioxidant Capacity of Prunus persica L. Juices

Peach and nectarine (Prunus persica ) production has an important place in the world, being the most important fruit after apple crops in the European Union. Because the fruits are perishable, it is desirable to valorize them as juice. Seven peaches and three nectarines cultivars grown in the N-W part of Romania were investigated for quality parameters, volatile profile, total phenols content and antioxidant capacity. The volatile composition of peach and nectarine cultivars was determined via the ITEX/GC-MS technique, the main volatile compounds belonging to alcohols and aldehydes. Another objective was to obtain the pasteurised juices from these fruits and to investigate the best time of pasteurisation in order to identify the most valuable cultivar from the perspective of total phenols content and its antioxidant capacity. For a better interpretation of results and a proper discrimination between cultivars, according to the total phenols content and antioxidant capacity, the multivariate analysis, Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA) were applied. The peach cultivars showed the highest content in total phenols compared with nectarine. From peach cultivars, the highest concentration was recorded in ‘Southland’ (47.49 ± 0.14 mg GAE 100 g-1 FW) and from nectarine cultivars in ‘Romamer’ (16.28 ± 0.83 mg GAE 100 g-1 FW). The highest antioxidant capacities were recorded in ‘Southland’ peach in the case of both methods (DPPH and FRAP). The results showed that ‘Southland’ peach and ‘Romamer’ nectarine pasteurised juices are the best from the point of view of total phenolic compounds content with high antioxidant capacity

The Effect of Different Pulsed Electric Field Treatments on Producing High Quality Red Wines

The aim of this study was to apply different Pulsed Electric Field (PEF) treatments in the pre-maceration stage of the mash which derives from ‘Pinot Noir’ and ‘Merlot’ grapes that were harvested in the Crişana-Santimreu vineyard, Romania, in 2016, in order to increase the content of total phenols, flavonoids, monomeric anthocyanin pigment and colour intensity of ‘Pinot Noir’ and ‘Merlot’ wines. The electrical and mechanical parameters that represent the variables in this experiment were: the distance between the drums, different voltages (7-8 kV), and different frequencies (178-344 Hz). The wines obtained were also analyzed in terms of the antioxidant capacity using two different methods. All PEF treatments applied in the pre-maceration stage resulted in an increase in bioactive compounds content and colour intensification. Of the five PEF treatments tested, the PEF treatment using the distance between the drums of 2.5 mm, U = 8 kV, the frequency f = 344 Hz, pulse durations of 300 s resulted in a wine with a content of total phenols 2 times and 1.5 times higher than the control sample in the case of ‘Pinot Noir’ and ‘Merlot’, respectively. Also, this type of PEF treatment also resulted in an extraction of the total flavonoids as efficiently as 1.8 times and 1.4 times, respectively, in the case of ‘Pinot Noir’ and ‘Merlot’, respectively. PEF treatment is a technology suitable for extracting phenols from grapes and so this technology can be used in the food industry to obtain wines rich in bioactive compounds with antioxidant capacity

OSF-Builder: A new tool for constructing and representing evolutionary histories involving introgression

Introgression is an evolutionary process which provides an important source of innovation for evolution. Although various methods have been used to detect introgression, very few methods are currently available for constructing evolutionary histories involving introgression. In this paper we propose a new method for constructing such evolutionary histories whose starting point is a species forest (consisting of a collection of lineage trees, usually arising as a collection of clades or monophyletic groups in a species tree), and a gene tree for a specific allele of interest, or allele tree for short. Our method is based on representing introgression in terms of a certain 'overlay' of the allele tree over the lineage trees, called an overlaid species forest (OSF). OSFs are similar to phylogenetic networks although a key difference is that they typically have multiple roots because each monophyletic group in the species tree has a different point of origin. Employing a new model for introgression, we derive an efficient algorithm for building OSFs called OSF-Builder that is guaranteed to return an optimal OSF in the sense that the number of potential introgression events is minimized. As well as using simulations to assess the performance of OSF-Builder, we illustrate its use on a butterfly dataset in which introgression has been previously inferred. The OSF-Builder software is available for download from https://www.uea.ac.uk/computing/software/OSF-Builde
