Cycle-to-cycle variations (CCV) in spark-ignited (SI) engines impose performance limitations and the extreme limit can lead to very strong, potentially damaging cycles. Thus, CCV force sub-optimal engine operating conditions. A deeper understanding of is key enabling control strategies, improving design reducing negative impact on operation. This paper presents a new simulation strategy which a...

Esta pesquisa tem como objetivo mapear o percurso percorrido pela criança na produção das líquidas /l, ɾ/ em ataques simples e complexos Português Brasileiro, delineando a interação entre aquisição segmental silábica durante desenvolvimento fonológico. Um estudo experimental comparando de 71 crianças 2;0 5;11 anos foi conduzido para responder três questões: i) CCV ocorre somente após CV, ou pod...

In 1990 Subramanian de ned the complexity class CC as the set of problems log-space reducible to the comparator circuit value problem (Ccv). He and Mayr showed that NL⊆CC⊆P, and proved that in addition to Ccv several other problems are complete for CC, including the stable marriage problem, and nding the lexicographically rst maximal matching in a bipartite graph. Although the class has not rec...

Many low- and middle-income countries (LMICs) report low rates of regional anesthesia (RA) use for cesarean delivery (CD), despite its association with lower maternal major morbidity and mortality. Also, the prevalence of neuraxial analgesia for labor (NAL) is often low in LMICs. We report on the results of a collaboration in clinical education over a multi-year period between Kybele Inc., an i...

Aim . To compare the efficacy and safety of chemical cardioversion (CCV) with refralon amiodarone in patients paroxysmal atrial fibril­lation flutter (AF/AFL). Material methods Fifty five (mean age, 65±11 years) AF/AFL were included. All underwent a preliminary examination to rule out contraindications CCV. Further, randomized into groups (n=30) (n=28), respectively. CCV was carried as follows:...

Museums, archives and other cultural image collections, often are requested to identify an image whose metadata are inaccurate or missing. The task is further complicated because the query image may be an extract of the original, and present distortions, such as scale changes and noise. The majority of solutions proposed to this task are based on classic image signatures, such as the color hist...

Color has been widely used in content-based image retrieval systems. The problem with using color is that its representation is low level and hence its retrieval effectiveness is limited. This paper investigates techniques to improving the effectiveness of image retrieval based on colors. It examines the choice of suitable color space and color resolution. It describes two techniques for image ...

INTRODUCTION Ethical conflict is one of ICU nurses' main problems, which rise for several reasons that must be measured. Unfortunately, there is no native instrument for measuring ethical conflicts for ICU nurses in Iran. One of the more suitable and new tools for the measurement of ethical conflict is called the "Ethical Conflict in Nursing Questionnaire: Critical Care Version (ECCNQ-CCV)." Th...

Clostridium perfringens (CP) is the etiologic agent of necrotic enteritis (NE). Clinical signs of this disease include depression, decreased appetite, diarrhea, and severe necrosis of the intestinal tract. Understanding the disease progression of NE has been difficult due to its complexity and the involvement of multiple factors (dietary components, immunosuppression, and mechanical irritation ...
