Cross correlation function (CCF) of signals is an important tool of multi-sensors signal processing. Parabola functions are commonly used as parametric models of the CCF in time delay estimation. The parameters are determined by fitting samples near the maximum of the CCF to a parabola function. In this paper we analyze the CCF for the stationary processes of exponential autocorrelation functio...

The effect of subtherapeutic concentrations of antibiotics (10.0 and 40.0 microg/mL of vancomycin, gentamicin, and tylosin) on the efficacy of a mixed anaerobe culture of chicken microflora (CCF) was studied in a continuous-flow fermentation system. Efficacy of CCF posttreatment was assessed by challenge with glycopeptide-resistant Enterococcus faecium (GRE) at 6.0 log10 cfu/mL. Bacterial enume...

Imperfect coverage (IPC) occurs when a malicious component failure causes extensive damage due to inadequate fault detection, fault location or fault recovery. Common-cause failures (CCF) are multiple dependent component failures within a system due to a shared root cause. Both imperfect coverage and common-cause failures can exist in distributed computer systems and can contribute significantl...

The deep cervical flexor (DCF) muscles are considered to be of substantial clinical importance in the management of neck pain. While conventional cervical flexion (CF) dynamometry methods have been used frequently to assess the capacity of the cervical flexor muscles, it has been suggested that cranio-cervical flexion (CCF) methods may provide a more specific test of DCF muscle performance. Thi...

The experiment investigated the effects of a supplemental candy coproduct (Chocolate Candy Feed [CCF]; International Ingredient Corp., St. Louis, MO), an alternative carbohydrate source to dietary lactose, on growth performance and on health status of nursery pigs. Crossbred pigs ( = 1,408; 21 d of age and 7.1 ± 0.3 kg BW; Smithfield Premium Genetics, Rose Hill, NC) were randomly assigned to 4 ...

coronary-cameral fistulas (ccfs) constitute a rare anomaly that can be incidentally detected during angiography. ccfs are solitary, large or small assemblies that originate from coronary arteries and enter one of the cardiac chambers. we describe a 29-year-old woman, who referred to our clinic with the chief complaints of palpitation, atypical chest pain, and dyspnea on exertion (functional cla...

We introduce a new technique for reducing the dimension of the ambient space of low-degree polynomials in the Gaussian space while preserving their relative correlation structure. As an application, we obtain an explicit upper bound on the dimension of an ε-optimal noise-stable Gaussian partition. In fact, we address the more general problem of upper bounding the number of samples needed to ε-a...

BACKGROUND Cholecystocolonic fistula (CCF) is the second most common cholecystoenteric fistula and is often discovered intraoperatively, resulting in a challenging situation for the surgeon, who is forced to switch to a complex procedure, often in old, unfit patients. Management of this uncommon but possible finding is still ill defined. METHODS An extensive review of 160 articles published f...

Abstract Mission-critical IEC 61850 system architectures are designed to tolerate hardware failures achieve the highest reliability performance. Hence, multi-channel systems used in such within industrial facilities isolate machinery when there process abnormalities. Inevitably, introduce Common Cause Failure (CCF) since subsystems can rarely be independent. This paper integrates CCF into Marko...

In dictionary learning, also known as sparse coding, the algorithm is given samples of the form y = Ax where x ∈ Rm is an unknown random sparse vector and A is an unknown dictionary matrix in R (usually m > n, which is the overcomplete case). The goal is to learn A and x. This problem has been studied in neuroscience, machine learning, visions, and image processing. In practice it is solved by ...
