Mr. Feldstein: I thought this was a helpful paper: interesting analysis and interesting data. I would like to comment primarily on the discussion of the eurozone, but first make a remark about what you said about mitigating portfolio risk, by increasing private portfolio investment abroad. I do not understand how, when problems arise, countries could cause these private foreign investments to b...

A constrained version of the Big Bang-Big Crunch algorithm for the efficient solution of the optimal reservoir operation problems is proposed in this paper. Big Bang-Big Crunch (BB-BC) algorithm is a new meta-heuristic population-based algorithm that relies on one of the theories of the evolution of universe namely, the Big Bang and Big Crunch theory. An improved formulation of the algorithm na...

‎Hensel [K‎. ‎Hensel‎, ‎Deutsch‎. ‎Math‎. ‎Verein‎, ‎{6} (1897), ‎83-88.] discovered the $p$-adic number as a‎ ‎number theoretical analogue of power series in complex analysis‎. ‎Fix ‎a prime number $p$‎. ‎for any nonzero rational number $x$‎, ‎there‎ ‎exists a unique integer $n_x inmathbb{Z}$ such that $x = ‎frac{a}{b}p^{n_x}$‎, ‎where $a$ and $b$ are integers not divisible by ‎$p$‎. ‎Then $|x...

Metal oxide surge arrester accurate modeling and its parameter identification are very important for insulation coordination studies, arrester allocation and system reliability. Since quality and reliability of lightning performance studies can be improved with the more efficient representation of the arresters´ dynamic behavior. In this paper, Big Bang – Big Crunch and Hybrid Big Bang – Big Cr...

Autumn daffodil (Sternbergia lutea) is one of bulbous plants from Iran that has potential as an ornamental plant. The understanding and control of dormancy and investigation of cold requirement in this plant are critical for its cultivation This research was conducted to investigate the effects of duration of cold and the size of bulb on growth, development and flowering of autumn daffodil. The...

This paper checks the correctness of our novel algorithm for secure, reliable and flexible transmission of big data in two-hop wireless networks using cooperative jamming scheme of attacker location unknown through Markovian process. Big data has to transmit in two-hop from source-to-relay and relay-to-destination node by deploying security in physical layer. Based on our novel algorithm, the n...

A hybrid variant of the Fuzzy C-Means and K-Means algorithms is proposed to solve large datasets such as those presented in Big Data. The algorithm sensitive initial values membership matrix. Therefore, a special configuration matrix can accelerate convergence algorithm. In this sense, new approach proposed, which we call Hybrid OK-Means (HOFCM), it optimizes parameter. This consists three step...

PURPOSE To investigate the relationship between distal symmetric peripheral neuropathy and early stages of autonomic bladder dysfunction in type 2 diabetic women. MATERIALS AND METHODS A total of 137 diabetic women with minimal coexisting confounders of voiding dysfunction followed at a diabetes clinic were subject to the following evaluations: current perception threshold (CPT) tests on myel...
