In this paper, we use known bounds on the smallest eigenvalue of a symmetric matrix and Schoenberg’s Theorem to provide both necessary as well as sufficient trace inequalities that guarantee a matrix D is a Euclidean distance matrix, EDM. We also provide necessary and sufficient trace inequalities that guarantee a matrix D is an EDM generated by a regular figure.

whereas in electrical discharge machining (edm) the heat flux entering the workpiece is extremely high, the fourier heat conduction model may fails. this article reports on determination of temperature distribution in the workpiece due to edm using non-fourier heat conduction model. equations are solved by deriving the numerical solution. the temperature layers and profiles of sample calculatio...

INTRODUCTION Oral erectile dysfunction medications (EDMs) have become an increasingly popular drug of abuse among young men without a medical indication. In addition to being associated with increased sexual risk behaviors, recreational EDM use may adversely impact psychological aspects of sexual function, primarily by affecting one's confidence in pharmacologically unaided erectile ability. To...

Symmetries of the Universe have always provided theoreticians with a powerful tool in their efforts to understand and unify physics laws. Three of them have shaped physics over the last 50 years: parity (P ), charge conjugation (C), and time-reversal (T ). Today, T -violation remains the most mysterious symmetry violation as it is not understood properly and as much stronger T -violating mechan...

The esophageal Doppler monitor (EDM) is a clinically useful device for minimally invasive assessment of cardiac output, preload, afterload, and contractility. An empirical model, based upon the logistic function, has been developed. Use of this model illustrates how the EDM could estimate the net effect of aortic and non-aortic contributions to inertia, resistance, and elastance within real tim...

EDM is an unconventional electro thermal machining process used for manufacturing geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining process. The process involves a controlled erosion of electrically conductive materials by the initiation of rapid and repetitive spark discharges between the tool and work piece separated by a small gap ...

Contemporary challenges for enterprise document management (EDM) include managing a mixture of technologies, recognizing the needs of several user roles and groups, and pursuing effective processes utilizing documents in digital form. Responding to these challenges means gathering and scrutinizing organizational metadata describing the organization's information resources. Despite the volume of...

Italian ryegrass (Lolium multiflorum Lam.) is one of the most important forage grass species in Europe. In Portugal 34% of the cultivated area is dedicated to animal fodder. Italian ryegrass area in Entre Douro e Minho (EDM) region was mainly with landraces. Changes in traditional agricultural systems are contributing to a major loss of genetic diversity mainly to landraces. Portuguese Italian ...

Abstract An n × n matrix D is a Euclidean distance matrix (EDM) if there exist p, . . . , pn in some Euclidean space such that dij = ||pi − pj ||2 for all i, j = 1, . . . , n. Let D be an EDM and let Eij be the n×n symmetric matrix with 1’s in the ijth and jith entries and 0’s elsewhere. We say that [lij , uij ] is the yielding interval of entry dij if it holds that D+ tE ij is an EDM if and on...
