ethno-musicology is an academic field encompassing various approaches to the study of music that emphasize its cultural, social, material, cognitive, biological, and other dimensions or contexts instead of its isolated ‘sound’ component or any particular repertoire. the term ‘ethno-musicology’ became common in1950, although the emergence of the field can be traced back to the late nineteenth ce...

pistachio nut is one of the most important export crops in iran. for prevention of rancidity and to ensure good quality, pistachio must be harvested in a short time and be prepared for drying in 24h.the ohadi variety of iranian raw dry pistachio nuts was selected for the experiments. instrumental hardness and sensory characteristics of pistachio nuts such as: flavor , texture and total acceptan...

Abstract The paper considers metrological instrumentation for studying the rheological properties of magnetic fluids. It also presents design a coaxial viscometer. There is analysis factors that affect measurement accuracy. Errors are systematized into 2 main groups: method and instrumental. authors analyse contribution each group to total error. established temperature instability liquid under...

The need of developing appropriate noise prediction models for finding out the accurate status of noise levels (>90 dBA) generated from various opencast mining machineries is overdue. The measured sound pressure levels (SPL) of equipments are not accurate due to instrumental error, attenuation due to geometrical aberration, atmospheric attenuation etc. Some of the popular noise prediction model...

We define a Byrnes-Isidori form for a class of infinite-dimensional systems with relative degree r and show that any system belonging to this class can be transformed into this form. We also analyze the concept of (stable) zero dynamics and show that it is, together with the Byrnes-Isidori form, instrumental for static proportional high-gain output feedback stabilization. Moreover, we show that...

The problem introduced by grouping income data when measuring socioeconomic inequalities in health (and health care) has been highlighted in a recent study in this journal. We re-examine this issue and show there is a tendency to underestimate the concentration index at an increasing rate when lowering the number of income categories. This tendency arises due to a form of measurement error and ...

We introduce the concept of local bucket error for the mini-bucket heuristics and show how it can be used to improve the power of AND/OR search for combinatorial optimization tasks in graphical models (e.g. MAP/MPE or weighted CSPs). The local bucket error illuminates how the heuristic errors are distributed in the search space, guided by the minibucket heuristic. We present and analyze methods...

We studied sample evaporation and its effect on analytical error. Several factors influencing evaporative loss have been identified and measured: environmental, instrumental, and operational factors, and the chemical and physical properties of the sample and its container. Such losses from several different types of sample cups have been measured, either chemically or gravimetrically, and compa...

This paper proposes a new instrumental variables estimator for a dynamic panel model with …xed e¤ects with good bias and mean squared error properties even when identi…cation of the model becomes weak near the unit circle. We adopt a weak instrument asymptotic approximation to study the behavior of various estimators near the unit circle. We show that an estimator based on long di¤erencing the ...
