One of the most promising applications of the family of electronic devices called Flexible AC Transmission System (FACTS) devices is to better regulate power flow in transmission grids. In particular, the Unified Power Flow Controller (UPFC) is the best choice for complete control of power flow control. By selecting proper installation locations and control techniques, UPFCs may be able to prev...

Observations (1978–1991) of distributions of pelagic juvenile Northeast Arctic cod (Gadus morhua L.) show that up to 1/3 of the year class are dispersed off the continental shelf and into the deep Norwegian Sea while on the way from the spring-spawning areas along the Norwegian coast to the autumn-settlement areas in the Barents Sea. The fate of this variable fraction of pelagic juveniles off-s...

Large-scale communications blackouts, such as those carried out by Egypt and Libya in 2011 and Syria in 2012 and 2013, have motivated a series of projects that aim to enable citizens to communicate even in the face of such heavy-handed censorship efforts. A common theme across these proposals has been the use of wireless mesh networks. We argue that such networks are poorly equipped to serve as...

A hidden failure embedded DC model of power transmission systems has been developed to study the power law distributions observed in North American blackout data. We investigate the impacts of several model parameters on the global dynamics and evaluate possible mitigation measures. The main parameters include system loading level, hidden failure probability, spinning reserve capacity and contr...

The aim of the New Zealand Southern ALPs EXperiment (SALPEX) was to study chiefly, but not exclusively, how the Southern Alps promote precipitation on the upwind side of the mountain chain in pre-frontal northwesterly airstreams. The third and most extensive field phase of the experiment ran for three weeks during October 1996, and documented two events in considerable detail. The present paper...

In this study, the electron-transfer properties of alkynylated indenofluorene-diones with various substituents (SiMe3, SiPr3, and SiPh3) that function as n-type organic semiconductors were comparatively investigated at the first-principles DFT level based on the Marcus-Hush theory. The reorganization energies are calculated by the adiabatic potential-energy surface method, and the coupling term...

Hitherto, the Malaconothridae contained Malaconothrus Berlese, 1904 and Trimalaconothrus Berlese, 1916, defined by the possession of one pre-tarsal claw (monodactyly) or by three claws (tridactyly) respectively. However, monodactyly is a convergent apomorphy within the Oribatida and an unreliable character for a classification. Therefore we undertook a phylogenetic analysis of 102 species as th...

Oncerotrachelus amazonensis sp. nov. and O. paraconformis sp. nov. from Amazonas, Brazil, are described. Oncerotrachelus conformis Uhler is recorded for the first time from Brazil and a description of male genitalia of this species is provided.

Temporal Data Warehouses (TDWs) allow to manage timevarying multidimensional data by joining the research of Temporal Databases and Data Warehouses. TDWs raise different issues such as temporal aggregations, multidimensional schema versioning, etc. However, very little attention from the research community has been drawn to conceptual modeling for TDWs and its subsequent logical representation....

The allene ether version of the Nazarov cyclization was used to construct the cyclopentane dione portion of madindolines A and B. The racemic cyclopentane dione from the Nazarov cyclization was converted to an enol ether that was combined with the chiral, nonracemic hydroxyfuroindoline in a Mannich reaction. Deprotection and oxidation led to (+)-madindoline A and (+)-madindoline B. [reaction: s...
