Network state is always in flux. Due to traffic engineering, topology changes, policy updates, VM migrations, etc., today’s networks undergo a variety of large updates that concurrently affect many switches. Transitioning between network states can be a source of instability, leading to outages, disruptions and security vulnerabilities. Consistent network updates [7] introduces a mechanism that...

Most expectation-maximization (EM) type algorithms for penalized maximum-likelihood image reconstruction converge slowly, particularly when one incorporates additive background effects such as scatter, random coincidences, dark current, or cosmic radiation. In addition, regularizing smoothness penalties (or priors) introduce parameter coupling, rendering intractable the M-steps of most EM-type ...

Let us remember the mechanics of Multiplicative-Weights-Updates: At every time t, the learner maintains a weight vector wt ≥ 0 over the experts. Given the weight vector, the probability distribution over the experts is computed as pt = wt wt·1 . The weights are initialized at w1 = 1 n · 1. (Multiplicative-weights-update step.) Given the loss vector at time t the weights are updated as follows w...

Sepsis is the most common cause of neonatal mortality. As per National Neonatal-Perinatal Database (NNPD), 2002-2003, the incidence of neonatal sepsis in India was 30 per 1000 live births. Signs and symptoms of sepsis are nonspecific; therefore empirical antimicrobial therapy is promptly initiated after obtaining appropriate cultures. The early manifestations of neonatal sepsis are vague and il...

Accurate numerical simulation of problems in fluid mechanics requires using a method whereby the mesh can track free surfaces or fluid-solid or fluidfluid interfaces whilst coping with large distortions of the continuum. Such methods are referred to as Arbitrary Lagrangian Eulerian (ALE) methods and may be furthered studied in [1]. In order for the mesh to adapt to the deforming domain, a mesh ...

State Machines Formal semantics for large part of UML using Abstract State Machines (Gurevich). Transition systems. States: multi-sorted first-order structures (set with function names and function interpretations). ASM: set of states (incl. initial state) and update rule.
