We study supergravity models in four dimensions where the hidden sector is superconformal and strongly-coupled over several decades of energy below the Planck scale, before undergoing spontaneous breakdown of scale invariance and supersymmetry. We show that large anomalous dimensions can suppress Kähler contact terms between the hidden and visible sectors, leading to models in which the hidden ...

We investigate whether cultural differences between professional decision-makers affect financial contracts in a large dataset of international syndicated bank loans. We find that lead banks offer smaller loans at a higher interest rate to more culturally distant borrowers. Furthermore, lead banks are more likely to require third-party guarantees as cultural distance with the borrower increases...

| In this paper some new results for multidimensional m-band bi-orthogonal lter banks are presented. In the rst part of the paper we introduce the ladder structure as a method for the design and implementation of aforementioned lter banks. The theory of ladders and the relation to lter banks is presented. The second part of the paper focuses upon linear phase conditions for bi-orthogonal lter b...

  In this paper, modeling and optimization of Fischer-Tropsch Synthesis is considered in a fixed-bed catalytic reactor using an industrial Fe-Cu-K catalyst. A one dimensional pseudo-homogenous plug flow model without axial dispersion is developed for converting syngas to heavy hydrocarbons. The effects of temperature, pressure, H2 to CO ratio in feed stream, and CO molar flow on the mass flow r...

A technique for mapping systolic FIR filter banks onto fixed-size processor arrays is presented. It is based on the time-sharing properties of c-slow circuits. The technique can be further developed to a formalism and holds high potential for automatic realization. It has been applied to the mapping of systolic filter banks onto a fixed-size array of Transputers.

this study investigated the effect, on reactor performance and biomass retention inside the bed, of the material used to make the supports of anaerobic fixed-bed reactors. three inert supports of similar shape but made of three different materials polyvinyl chloride, polypropylene, high-density polyethylene were manufactured and used. all three supports had the same specific surface area but di...

The coupling of reactions in catalytic membrane reactors provides novel reactor configurations that allow shifting the thermodynamic equilibrium and yields of thermodynamically limited reactions and enhancing significantly the rate of production. An interesting pair to couple is the dehydrogenation of ethylbenzene to styrene and the hydrogenation of nitrobenzene to aniline. Hydrogen produced in...

The high penetration of renewable energy into distribution networks poses increasing challenges on voltage control. To address this issue, paper presents a double-layer stochastic model predictive control algorithm to regulate profile in active networks. In the proposed algorithm, regulation is achieved by coordination an upper layer controller and lower controller. layer, number operation mech...
