To what extent is public debt private liquidity? Much policy advice given in the aftermath of the financial crisis rests on the assumption that increasing public debt relaxes borrowing constraints of private households. This is the case for ad-hoc debt limits, which are exogenous to public policy. Instead, if debt limits are fully endogenous, as e.g. in the case of the natural borrowing limit, ...

Anonymous communication systems ensure that correspondence between senders and receivers cannot be inferred with certainty. However, when patterns are persistent, observations from anonymous communication systems enable the reconstruction of user behavioral profiles. Protection against profiling can be enhanced by adding dummy messages, generated by users or by the anonymity provider, to the co...

The fan laws, particularly what the limits are in their use is described. The derivation is covered very briefly. To help understand some of the fan law uses, centrifugal impeller characteristics are covered, particularly some of the things controlling the shape of the curve. A discussion of the fan law deviations in an individual impeller is covered. Multistage centrifugals are covered using t...

Social computation is a paradigm in which a software application supports social interaction, but whose real purpose is the data trail that is left by that interaction, such as tags, recommendations, and so on. We explore a possible imperfection in the data that is generated by these games. Specifically, we investigate whether the data generated by previous participants influences the data that...

We consider a centralized coded caching system consisting of a server delivering N popular files, each of size F bits, to K users through an error-free shared link. Each user is equipped with a local cache of capacity MF bits. The contents can be proactively cached into the user caches by the server over low traffic period; however, without the knowledge of the user demands. During the peak tra...

In this work an attempt has been made to analyze the scaling limits of Double Gate (DG) underlap and Triple Gate (TG) overlap FinFET structure using 2D and 3D computer simulations respectively. To analyze the scaling limits of FinFET structure, simulations are performed using three variables: finthickness, fin-height and gate-length. From 2D simulation of DG FinFET, it is found that the gate-le...

Temporal differences in foraging rhythms, at both daily and seasonal levels, are common among sympatric ant species (Lynch, Balinsky & Vail 1980; Lynch 1981; Herbers 1985, 1989; Lynch, Johnson & Balinsky 1988; Marsh 1988; Fellers 1989; Samways 1990). Although the temporal partition of interspecific foraging shifts is considered to be one of the consequences of interspecific competition, tempora...

I n this paper‘ we explore the fundamental limits of input mte control by spectral analysis in frequency domain. Both deterministic and stochastic analyses are developed. Especially, the simple deterministic analysis helps us to gain a great knowledge of performance trade-off for input rate control in high speed network.

The performance of a bit-interleaved coded OFDM system disturbed by phase noise is investigated. The sensitivity is calculated as a function of the 3 dB phase noise bandwidth for several QAM constellations. The results for BER and cut-off rate (capacity) are closely related and illustrate the performance limits and required oscillator stability for an AWGN and an exemplary fading channel.

With intermittently operated municipal waste water plants the aeration switching sequence should be optimized under the constraints that the solved nitrogen concentration in effluent has to be kept within its environmental limits. This is a highly nonlinear control problem because of the nonlinear biological process model ASM1 (Activated Sludge Model 1), the on-off state of the manipulated sequ...
