among the most important sources of competitive advantage, is creating and developing strategic alignment competency. strategic alignment, literally, is an abstract and qualitative concept. and a qualitative concept while not been quantified and operationalized, does not worth paying attention practically. this article basing on a general formula and taking systems dynamics approach, suggests a...

it development and its ease of use have caused the organizations to equip their processing and operations through it. it has been over a century that performance assessment has been a significant issue for management and actually has been performed in different ways. the current study aims to discover the effect of e-mail on performance assessment. therefore, mixed method has been used. the res...

As the absence of effective depictive expression of uncertain information effects the effectively selection of optimum state, the selection method of optimum state of qualitative modeling and reasoning process in complex system based on QSIM and cloud model is proposed. Firstly the calculation method of similarity degree using the distance based on cloud model is given. Then the selection metho...

Pagetoid reticulosis, also known as Woringer-Kolopp disease, is a rare variant of cutaneous T-cell lymphoma usually presenting as an isolated patch or plaque on the extremities. Immunohistochemical staining of T-cell markers can be variable, but as the name implies the epidermotropic lymphocytes consistently display a "pagetoid" appearance. The following case demonstrates clearance of this cond...

This study proposes a simple and reliable feature selection algorithm for ECG signals which can be applied on heartbeat case determining. A well-established technique, Principal Component Analysis (PCA), is employed for qualitative feature selection in this study. Determination of heartbeat case is carried out by fuzzy logic and Fisher’s linear discriminant analysis (Fisher’s LDA). The proposed...
