The Lending-Limit Combination Rules: Regulation by Enforcement at the OCC

The regulation-by-enforcement critique has made an impact at the Securities and Exchange Commission, and scholars are beginning to turn this critique against other agencies. Using this critique, this Note demonstrates that the federal combination rules for the lending-limit law should be rewritten. Under the lending-limit law, national banking associations may lend only a certain percentage of their unimpaired capital and unimpaired surplus to any one borrower. Although the combination rules include several per se rules pursuant to which loans made to two borrowers will be aggregated, they also grant the Office of the Comptroller of the Currency (OCC) the power to determine ad hoc whether to aggregate two loans. This power to determine on an ad hoc and even on a post hoc basis whether a violation of the law has occurred is an affront to the rule of law and is unfair to the industry. The combination rules should be amended to remove the OCC\u27s power to make ad hoc determinations

Plans for wind energy system simulation

A digital computer code and a special purpose hybrid computer, were introduced. The digital computer program, the Root Perturbation Method or RPM, is an implementation of the classic floquet procedure which circumvents numerical problems associated with the extraction of Floquet roots. The hybrid computer, the Wind Energy System Time domain simulator (WEST), yields real time loads and deformation information essential to design and system stability investigations

Wind energy system time-domain (WEST) analyzers

A portable analyzer which simulates in real time the complex nonlinear dynamics of horizontal axis wind energy systems was constructed. Math models for an aeroelastic rotor featuring nonlinear aerodynamic and inertial terms were implemented with high speed digital controllers and analog calculation. This model was combined with other math models of elastic supports, control systems, a power train and gimballed rotor kinematics. A stroboscopic display system graphically depicting distributed blade loads, motion, and other aerodynamic functions on a cathode ray tube is included. Limited correlation efforts showed good comparison between the results of this analyzer and other sophisticated digital simulations. The digital simulation results were successfully correlated with test data

Physical Zero-Knowledge Proofs for Akari, Takuzu, Kakuro and KenKen

Akari, Takuzu, Kakuro and KenKen are logic games similar to Sudoku. In Akari, a labyrinth on a grid has to be lit by placing lanterns, respecting various constraints. In Takuzu a grid has to be filled with 0's and 1's, while respecting certain constraints. In Kakuro a grid has to be filled with numbers such that the sums per row and column match given values; similarly in KenKen a grid has to be filled with numbers such that in given areas the product, sum, difference or quotient equals a given value. We give physical algorithms to realize zero-knowledge proofs for these games which allow a player to show that he knows a solution without revealing it. These interactive proofs can be realized with simple office material as they only rely on cards and envelopes. Moreover, we formalize our algorithms and prove their security.Comment: FUN with algorithms 2016, Jun 2016, La Maddalena, Ital

Ray Flynn's Legacy: American Cities and the Progressive Agenda

Raymond Flynn won Boston's mayoralty in 1983 after a virtual tie in the preliminary election, as he and Mel King led a field of nine, each with approximately 29 percent of the votes. Both were neighborhood activists who had been in the state legislature. Both had been underdogs in the preliminary election, but defeated a better financed developer-friendly candidate. In the general election Flynn, white and from South Boston, won handily over King, a black who was on the faculty at MIT. The Boston Globe, endorsing Flynn, argued that he was in a better position to reach out to South Boston conservatives. One King supporter, perhaps unsurprised by the outcome, commented: "...they elected the two most pro neighborhood people as finalists and then what followed was ... neighborhood forums where you were hearing different theories of community empowerment and organizing ... it was really an education for the whole populace." In this retrospective, Peter Dreier, a housing activist who became Flynn's housing policy advisor, describes the results as they unfolded in City Hall: significant accomplishments against a troubled history marred by the busing conflicts of the previous decade
