This paper presents a tutorial introduction to the construction of finite-automata on infinite words from linear-time temporal logic formulas. After defining the source and target formalisms, it describes a first construction whose correctness is quite direct to establish, but whose behavior is always equal to the worst-case upper bound. It then turns to the techniques that can be used to improve this algorithm in order to obtain the quite effective algorithms that are now in use. [less ▲]

The Number Decision Diagram (NDD) has recently been proposed as a powerful representation system for sets of integer vectors. In particular, NDDs can be used for representing the sets of solutions of arbitrary Presburger formulas, or the set of reachable states of some systems using unbounded integer variables. In this paper, we address the problem of counting the number of distinct elements in a set of vectors represented as an NDD. We give an algorithm that is able to perform an exact count without enumerating explicitly the vectors, which makes it capable of handling very large sets. As an auxiliary result, we also develop an efficient projection method that allows to construct efficiently NDDs from quantified formulas, and thus makes it possible to apply our counting technique to sets specified by formulas. Our algorithms have been implemented in the verification tool LASH, and applied successfully to various counting problems. [less ▲]

every commercial steel product in varying amounts. Since inclusions significantly influence properties and behaviour of materials and at the same time give indications on the quality of the steel, it is quite interesting to precise their nature and their origin. In this paper concerning a project involved in the COST 517 framework, studied alloys are high alloy steels. The raw materials were obtained from the conventionally electrical cast ingot and the Electro Slag Refining processes. The purpose is to compare various inclusions produced by these different processes and their effect on the mechanical properties. The raw material because of the melting processes themselves, leads to a product with a good to a great cleanliness, and tiny inclusions, which are haphazardly distributed. The actual ASTM E45 chart seems to be inappropriate, as the inclusions founded are too small in size. Therefore, we manage to develop a specific procedure for the study of such inclusions. The different types of inclusions encountered are oxides, titanium nitrides, and manganese sulphides. Studying the effect on mechanical properties, oxides often seem to initiate fatigue fracture.

Differences in glucosinolate degradation products related to aphid and Brassicaceae host plant myrosinases

Studies on chemical ecology of host plant selection by herbivores were largely carried out to explain the diversity of secondary plant chemicals and host specialisation of herbivores. The glucosinolate – isothiocyanate system in Brassicaceae plants was considered as a plant defence and was known to influence the feeding behaviour of phytophagous insects such as the cabbage aphid, Brevicoryne brassicae. Purified myrosinases from the latter and from white mustard, Sinapis alba, were used to hydrolyse two glucosinolate compounds. Identification of the degradation products, mainly isothiocyanates, was performed by gas chromatography – mass spectrometry. While sinigrin hydrolysis gave identical isothiocyanates for insect and plant enzymes, B. brassicae myrosinase showed a particular activity toward sinalbin. A lost of an hydroxy group was observed for the two latter substrates related products when compared to the S. alba enzymatic specificity. Aphid and plant myrosinases have different properties and specificities which can be discussed in relation to a co-evolution approach. [less ▲]

Glucosinolates belong to a structurally homogeneous family of more than 110 miscellaneous secondary metabolites mostly contained in Brassicaceae. They are easily hydrolyzed into isothiocyanates, oxazolidinethiones, cyanides, D-glucose, sulphate ion… by an endogenous enzyme called myrosinase (thioglucoside glucohydrolase, EC 3.2.3.1). Glucosinolates and their breakdown compounds are partly or mainly responsible of the flavor of some foods (mustard, radish, horse-radish….) and are also suspected to play a role in cancer prevention (glucoraphanin in Broccoli). On an other hand, when present in rapeseed or canola, these molecules are easily broken down during animal digestion, leading to compounds with detrimental and antinutritional characteristics. They are known to interfere with the thyroid and to damage vital organs. [less ▲]

This paper presents a constitutive law based on Taylor's model implemented in our non linear finite element code LAGAMINE. The yield locus is only described and a particular interpolation method has been developed. This local yield locus model uses a discrete representation of the material's texture. The interpolation method is presented and a deep-drawing application is simulated in order to show up the influence of the texture evolution during forming processes. [less ▲]

This communication aims at reporting the superconducting properties of several bulk melt-processed DyBa2Cu3O7-x samples determined by using various measuring techniques. The original single domain material was first cut into 9 similar cubic samples which have been characterized by AC susceptibility, flux profiles and DC magnetization. The results indicate good quality melt-processed (RE)BCO materials with Tc = 89 K. Next, the effect of post oxygen annealing treatments on these samples was studied. The influence of the non-uniformity of the oxygen content on the magnetic property anisotropy is discussed. Finally, additional magnetic measurements were carried out by using a couple of parallel pick-up coils wound on the same sample. From the results we conclude that geometric effects have to be taken into account in order to extract the critical current density from the magnetic properties. [less ▲]

This paper presents the results of the investigation of the biological activity that takes place in four municipal solid waste landfills situated in different regions of two dry climate countries i.e. Haiti and Tunisia. Since the climatic water balance is negative (potential evapotranspiration being 1.5 to 5 times higher than rainfall), it has often been considered that this kind of landfill has neither environmental impact nor efficient biological activity. However, the four landfills revealed a biological activity with biogas often containing more than 60 percent of methane. Indeed, under the upper waste layer that was effectively dry (dry weight from 85 to 98 %), the core of refuse contained between 35 and 65 % of dry matter. In some boreholes, the produced gases periodically expelled leachates like small geysers. Therefore, the results assess that landfill management in countries with dry climate should be considered with adapted technologies, not necessary the same as under temperate or humid climates [less ▲]
