We analyze the impact credit constraints have on how firms structure their dealings with their partners in the supply chain; and hence how imperfect capital markets can alter short run prices and long run investment levels. Credit constrained firms are shown to become endogenously risk averse and so seek to push some risk onto suppliers. Our predictions reflect risk sharing contracts in general...

Many methods have been developed for spectral analysis of irregularly sampled data. Currently, popular methods such as Lomb–Scargle and resampling tend to be biased at higher frequencies. Slotting methods fail to consistently produce a spectrum that is positive for all frequencies. In this paper, a new estimator is introduced that applies the Burg algorithm for autoregressive spectral estimatio...

Ethernet is the most widely used network and many analytical models were developed to predict its capacity. Usually in these models assumptions like infinite population, no back-off algorithm and slotted channel are made. By comparing two models (one slotted and the other non-slotted) with reported measurements, we showed the optimistic estimate of the channel capacity of the slotted model is n...

Abstract: The axial magnetic-field-modulated brushless double-rotor machine (MFM-BDRM) is a novel possible alternative power-split device for hybrid electric vehicles (HEVs). This paper proposes a two-dimensional (2-D) analytical method to predict the performance of the axial MFM-BDRM to reduce computing time. The computation is based on the solution of Laplace’s or Poisson’s equation with boun...

The industry landscape in telecommunications is changing rapidly at the moment. Services are increasingly shifting from voice to data and from circuit-switched to packet-switched ones. LTE and WiMAX are the two technologies poised to dominate next generation mobile networks. Battle between LTE & WiMAX technologies is already heating up with WiMAX being ahead due to availability of standards thr...

Many methods have been developed for spectral analysis of irregularly sampled data. Current popular methods such as Lomb-Scargle and resampling tend to be biased at higher frequencies. Slotting methods fail to consistently produce a spectrum that is positive for all frequencies. In this paper, a new estimator is introduced that applies the Burg algorithm for AR spectral estimation to unevenly s...

Stainless steel square-honeycombs have been manufactured by slotting together steel sheets and then brazing the assembly. Their out-of-plane compressive response has been measured as a function of the relative density, the ratio of specimen height to cell size, and the degree of constraint associated with bonding of the honeycomb to face-sheets. It has been found that, for the practical range o...
