In this study, the engineering background of No. 2 complex connecting passage Binhu Road Station/Jinhu Square Station Nanning Metro Line 3 is investigated, where artificial ground freezing technique adopted. A three-dimensional finite element model established to investigate temperature development frozen soil curtain, with a simulation dynamic evolution frosted curtain. The validated by compar...

this paper attempts to examine the effect of water spreading on soil physico-chemical properties, and vegetative characteristics of common mesquite. for this, on the basis of flood water discharge, three sections of lands were accurately selected at kosar water spreading experimental station, in tangestan, bushehr province. in each section, 6 profiles were digged out and studied; meanwhile soil...

In this paper we examine the use of hypotheticals as a heuristic device to assist a case-based reasoner test the strengths, weaknesses, and ramifications of an analysis or argument by exploring and augmenting the space of known cases and indirectly, the at tendant spaces of doctrine and argument. Our program, HYPO, works in the task domain of the law, particularly, the area of trade secret prot...

In this paper, we empirically test the relation between price discrimination and product market competition in a two-sided market environment using a new data set of Spanish local TV stations that provides information on subscription and advertising prices per station for 1996, 1999 and 2002. Due to changes in regulation during this period affecting the degree of local market competition, we us...

Square is a multivariate quadratic encryption scheme proposed in 2009. It is a specialization of Hidden Field Equations by using only odd characteristic elds and also X as its central map. In addition, it uses embedding to reduce the number of variables in the public key. However, the system was broken at Asiacrypt 2009 using a di erential attack. At PQCrypto 2010 Clough and Ding proposed two n...

Dans une permutation, un record est maximum ou minimum, en partant de la droite gauche. Les éléments d’une permutation peuvent être classés deux types : les records (dits points extérieurs) et autres intérieurs). permutations sans point intérieur ont été étudiées sous le nom carrées. Ici, nous explorons ayant nombre fini intérieurs, dites quasi-carrées. Contrairement aux carrées, l’énumération ...

The article is devoted to the study of structure rhyme field CITY. Its microfields are outlined and their lexical composition analyzed. It was revealed that clearly formed via “urban space” (“structure space”, “urbanonyms”), “buildings institutions”, “objects materials”, “transport”. “Structure contains words: avenue, alley, boulevard, street, square, park, suburb, market, garden, square etc. R...

Spatial cross-validation and average-error statistics are examined with respect to their abilities to evaluate alternate spatial interpolation methods. A simple crossvalidation methodology is described, and the relative abilities of three, dimensioned error statistics—the root-mean-square error (RMSE), the mean absolute error (MAE), and the mean bias error (MBE)—to describe average interpolator...

The security problems like confidentiality, knowledge integrity ,and freshness in knowledge aggregation become crucial once these WSN is deployed in a very remote or hostile atmosphere wherever sensors square measure at risk of node failures and compromises. there's a presently analysis potential in securing knowledge aggregation in WSNs. inside this mind, the protection problems in knowledge a...
