Diversi®ed ®rms trade at a discount relative to comparable portfolios of stand-alone ®rms. One explanation is that these ®rms have inecient internal capital markets. We examine the link between ®rm value and the value of internal capital markets using a new form of corporate restructuring called tracking stock. We present a model that illustrates that the announcement e€ect of a tracking stock...

This paper presents a simplified hybrid pulsewidth modulation (HPWM) algorithm to reduce the steady state ripple in current. In the conventional space vector PWM (CSVPWM) algorithm, the zero voltage applying time is distributed equally in every sampling interval. Also, this paper deals with two discontinuous PWM (DPWM) algorithms, which use only one zero state in each sampling interval. The pro...

Current mitigation levels for noise transients impinging on marine mammals are specified by rms pressures. The rms measure critically relies upon choosing the size of averaging window for the squared pressures. Derivation of this window is not standardized, which can lead to 2-12 dB differences in rms sound pressure for the same wave forms. rms pressure does not represent the energy of the nois...

Primary rhabdomyosarcoma (RMS) of the kidney is a rare malignant mesenchymal tumor with an aggressive clinical course. Adult renal RMS is typically a pleomorphic histologic subtype and only a few cases have ever been reported. We herein present a new case of renal RMS of the embryonal histologic subtype in a 26-year-old woman.

Recent empirical literature documents value-destroying \crosssubsidization" among the divisions of diversi ed rms. However, this literature relies upon two maintained hypotheses: that divisions of diversi ed rms are randomly allocated to their corporate parents and that the investment opportunities facing conglomerate divisions are identical to those of stand-alone rms in their industries. This...

Through the introduction of economic principles, a Resource Management System (RMS) can incorporate user valuations and externalities such as the usage cost of resources, into its scheduling logic. Consequently, an economic RMS can extract more value from the available infrastructure compared to traditional RMSs. In order to use the available infrastructure efficiently, a grid RMS must take an ...
