This longitudinal study was conducted to determine (a) the rate of co-occurrence of reading disabilities (RDs) in a writing disability (WD) population of students followed from first grade to fourth grade and (b) the cognitive burden that is assumed by having a WD and a RD (WD + RD). The sample included 137 first-grade students from a single school district who initially were placed into three ...
defuzzifier circuit is one of the most important parts of fuzzy logic controllers that determine the output accuracy. the center of gravity method (cog) is one of the most accurate methods that so far been presented for defuzzification. in this paper, a simple algorithm is presented to generate triangular output membership functions in the mamdani method using the multiplier/divider circuit and...
مقدمه: گزارش های وجود asc-us (atypical squamous cells of undetermined significance)، asc-h (atypical squamous cells- cannot exclude high-grade squamous intraepithelial lesion)، lsil (low-grade squamous intraepithelial lesion) و hsil (high-grade squamous intraepithelial lesion) در پاپ اسمیر از جمله گزارش هایی هستند که نیاز به پی گیری دارند. این مطالعه، با هدف تعیین فراوانی asc-us، asc-h، lsil و ...
We present new tools for fuzzy arithmetic with fuzzy numbers, based on the parametric representation of fuzzy numbers and new fuzzy operations, the generalized difference and the generalized division of fuzzy numbers. The new operations are described in terms of the parametric LR and LU representations of fuzzy numbers and the corresponding algorithms are described. An application to the soluti...
The TEE model for grades of membership claims that there is a connection between the fact that an object is labeled (e.g., =old) in a natural language discourse on the one hand; and the assignment to the object of a high grade of membership in on the other. In preparation for a more precise formulation of this assertion we de ne here 1) LB (labeling) and 2) YN (yes-no) experiments which simulat...
We introduce an efficient and dynamic resource allocation mechanism within the framework of a cooperative game with fuzzy coalitions. A fuzzy coalition in a resource allocation problem can be so defined that membership grades of the players in it, are proportional to the fractions of their total resources. We call any distribution of the resources possessed by the players, among a prescribed nu...
Data on functional disability are of widespread policy interest in the United States, especially with respect to planning for Medicare and Social Security for a growing population of elderly adults. We consider an extract of functional disability data from the National Long Term Care Survey (NLTCS) and attempt to develop disability profiles using variations of the Grade of Membership (GoM) mode...
Poor information means incomplete and insufficient information, such as small sample and unknown distribution. For point estimation under the condition of poor information, the statistical methods relied on large sample sizes and known distributions may become ineffective. For this end, a fusion method is proposed. The fusion method develops five methods, three concepts, and one rule. The five ...
in this study, the roll, yaw and depth fuzzy control of an au- tonomous underwater vehicle (auv) are addressed. yaw and roll angles are regulated only using their errors and rates, but due to the complexity of depth dynamic channel, additional pitch rate quantity is used to improve the depth loop performance. the discussed auv has four aps at the rear of the vehicle as actuators. two rule bases...
This study examined the acculturative and psychosocial predictors of academic-related outcomes among Cambodian American high school students from an urban school district in the state of Massachusetts. Student participants (N = 163) completed an anonymous survey that assessed demographic characteristics, acculturative experiences, intergenerational conflict, depression, and academic-related out...
