to determine the effective factors on yield performance of corn, 40 corn growers were selected using two stages sampling method from orzooeyeh in kerman province. data were collected by questionnaires and interview. frontier production function and technical unefficiency function were estimated with front. 4 software. using dalinous method the selected corn growers divided to three groups a...
This paper presents a variable-rate CELP codec which achieves good communications speech quality at an average rate of about 3 kb/s. The codec operates as a source-controlled variable rate coder with rates of 4.9 kb/s for voiced and transition sounds, 3.0 kb/s for unvoiced sounds and 670 b/s for silent frames. New techniques used in the codec include prediction of the xed codebook target vector...
The third-party motor insurance data from Sweden for 1977 described by Andrews and Herzberg in 1985 contain average claim occurrence rate (P c ) , size (C a category of vehicles specified the kilometres travelled per year (K), geographical zone (Z), no claims bonus (B) make car (M). categorical variables Z M may first be represented respectively vectors (Z 1 2 … 6 (M 8 binary variables. variabl...
Background and Aim: Notwithstanding the benefits of radiography, the staff of radiography wards must take necessary care to minimize their own and patients’ exposure to harmful rays. Therefore, the present paper aimed at assessing the radiolographers’ awareness and performance concerning technical and protective principles. Materials and Methods: In this descriptive-analytical study, all the 26...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
this study aimed to measure the hospital productivity using data envelopment analysis (dea) technique and malmquist indices.this is a cross sectional study in which the panel data were used in a 4 year period from 2007 to 2010. the research was implemented in 12 teaching and non-teaching hospitals of ahvaz county. data envelopment analysis technique and the malmquist indices with an input-orien...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
Background: The rejected films in radiography may be responsible for an unnecessary increase in the radiation dose to the population. The effective dose to population is a very important factor in estimation of stochastic risk in radiology. The main goal of this study was to determine the effective dose to members of the public due to rejected films in diagnostic radiology departments in the No...
