coustic emission (AE) techniques have been used * of arrival-time differences (delta-T’s) for each mesh point. To in the study of crack location, cracking mecha‘ calculate the source position for a set of burst-type AE signisms, deformation of metals and leak detection. : nals, a straightforward “shift and a d d method was used. A In these techniques, AE sensors hit by transient . First, assumi...

Mortar samples were saturated with NaCl solutions of various concentrations and subjected to freeze– thaw cycles. Passive and active acoustic emission (AE) testing was conducted. The freezing temperature of the NaCl solutions in mortar corresponded with the sudden observation of passive AE events. The acoustic energy and damage parameter were calculated to evaluate the extent of freeze–thaw dam...

An experiment was conducted at the Soil Science Field Laboratory of Bangladesh Agricultural University, Mymensingh during November 2011 to March 2012 to evaluate the effect of integrated use of manures and fertilizers on the growth, yield and nutrient uptake by wheat. There were six treatments such as T0 (Control), T1 [STB-CF (HYG)], T2 [CD + STB-CF (HYG)], T3 [PM + STB-CF (HYG)], T4 [COM + STB...

∂tφ+ ∂xf(φ) = 0, φ(x, 0) = φ0(x). In particular, when two components take the same initial value as φ0, the exact solution of conservation laws is precisely captured by the approximate system. In this paper we develop a class of local Alternating Evolution (AE) schemes, where we take advantage of high accuracy of the AE approximation. Our approach is based on a sliding average of the AE system ...

Studies of postmeiotic chromosomes have been impeded by the thick exine of immature pollen grains. Chromosome staining of immature and adult pollen grains through conventional acetocarmine procedure is tedious and often leads to unsatisfactory results. An acetocarmine stain, used in conjugation with Carnoy’s solution as fixative for 72 hrs or until the chlorophyll-containing tissues of spike be...

The paper presents a new Artificial Neural Network (ANN) encoding method called Assembler Encoding (AE). It assumes that the ANN is encoded in the form of a program (Assembler Encoding Program, AEP) of a linear organization and of a structure similar to the structure of a simple assembler program. The task of the AEP is to create a Connectivity Matrix (CM) which can be transformed into the ANN ...

carum copticum is a grassy and annual plant which is believed to have several therapeutic effects, including anti-asthmatic properties. we have therefore studied the bronchodilatory and anticholinergic effects of 4 rnl aqueous extract (ae), 0.0 5 ml ethanol extract (ee), and 0.0 0 5 ml essential oil (eo) of carum copticum and 1 rnl of a 5 mm solution of its main ingredient, thymol (t), in compa...

1 (a) Claim: R[X, Y ] is not a Euclidean domain. Proof: If R[X, Y ] was a Euclidean domain, then it would be a principal ideal domain. But consider I = (x, y) = (x) + (y). I is certainly not a principal ideal, as if it were, there would be some polynomial, g that divides everything in I, so g would divide x, implying that g does not contain any monomials with positive degree in y, and likewise ...

We argue that reading comprehension tests are not particularly suited for the evaluation of NLP systems. Reading comprehension tests are specifically designed to evaluate human reading skills, and these require vast amounts of world knowledge and common-sense reasoning capabilities. Experience has shown that this kind of full-fledged question answering (QA) over texts from a wide range of domai...
