synchronous cancer is referred to two or more histological distinct malignancies diagnosed during the same hospital admission. globally more than 1 million people get colorectal cancer yearly resulting in about 0.5 million deaths. vulvar cancer is the fourth most common gynecologic cancer (following the corpus uterine cancer, cancer of ovary and cervix) and comprises only 4 percent of malignanc...
paragangliomas in the head and neck are found typically in the region of the carotid body, jugular body, and along the 9th and 10th cranial nerves. they can occur in multicenteric forms, but generally, laryngeal paragangliomas are not found in these patients. only two cases of laryngeal paraganglioma have been reported with a synchronous lesion elsewhere. we report an additional case of a 34-ye...
مقدمه: سرطان پستان دو طرفه، پدیده ای است که چندان شایع نمی باشد و فراوانی، عوامل خطر پیش بینی کننده و پیش آگهی آن هنوز مورد بحث بوده و به خوبی شناخته نشده اند. هدف از این مطالعه بررسی موارد سرطان پستان دوطرفه و بقاء این بیماران در مراجعه کنندگان به مرکز بیماری های پستان جهاد دانشگاهی واحد علوم پزشکی تهران است. روش بررسی: در یک مطالعه گذشته نگر بر اساس اطلاعات ثبت شده بیماران مبتلا به سرطان پس...
This paper represents the performance of a squirrel-cage High Temperature Superconducting Induction/ Synchronous Motor (HTS-ISM) based on nonlinear electrical equivalent circuit. The structure of the HTS-ISM is the same as that of the squirrel-cage type induction machine, and the secondary windings are fabricated by the use of the HTS wires. It has already been shown that based on the experimen...

Brushless doubly fed machine (BDFM) is indeed an induction machine which has two windings in the stator and a cage rotor with a special design. Due to absence of brushes and slip rings, this machine is considered for the applications needs high reliability, such as wind turbines. In this paper, stead state performance of BDFM in synchronous mode of operation, the most interesting mode of operat...
Stability of synchronous state is a fundamental problem in synchronization. We study Matrix Measure as an approach for investigating of stability of synchronous states of chaotic maps on complex networks. Matrix Measure is a measure which depends on network structure. Using this measure and comparing with synchronization threshold which depends on the function of the map, show us how the synchr...
this paper presents the application of radial basis neural networks to the development of a novel method for the condition monitoring and fault diagnosis of synchronous generators. in the proposed scheme, flux linkage analysis is used to reach a decision. probabilistic neural network (pnn) and discrete wavelet transform (dwt) are used in design of fault diagnosis system. pnn as main part of thi...

In the present work, an integrated method of pole shape design optimization for reduction of torque pulsation components in permanent magnet synchronous motors is developed. A progressive design process is presented to find feasible optimal shapes. This method is applied on the pole shape optimization of two prototype permanent magnet synchronous motors, i.e., 4-poles/6-slots and 4-poles-12slots.
