Ehrlichiosis is a worldwide distributed disease caused by different bacteria of the Ehrlichia genus that are transmitted by arthropod vectors. Its occurrence in dogs is considered endemic in several regions of Brazil. Regarding cats, however, few studies have been done and, consequently, there is not enough data available. In order to detect Ehrlichia spp. in cats from the central-western regio...

Previous research (e.g., Leung, Chang, & Hau, 2001; Yi & Chang, 2001) has shown that the astratified method with content blocking (STR_C) performed well in content balancing constrained computerized adaptive tests (CATs). It effectively reduced the exposure rates of highly discriminating items, produced more balanced item usage within a pool, and maintained measurement precision. This method, h...

objective: interest in the subject of creativity and its impacts on human life is growing extensively. however, only a few surveys pay attention to the relation between creativity and physiological changes. this paper presents a novel approach to distinguish between creativity states from electrocardiogram signals. nineteen linear and nonlinear features of the cardiac signal were extracted to d...

Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) are among the most common infectious diseases of cats. Although vaccines are available for both viruses, identification and segregation of infected cats form the cornerstone for preventing new infections. Guidelines in this report have been developed for veterinary practices, breeders, shelters, and cat owners to use for diagn...

TEA was originally conceived as a Computer Aided Educational System for teaching Agrarian Economy. This system was composed by web pages of instructional contents and web pages of test questions. The biggest flaw of the system is the lack of control over the pages seen by the student. This contributed to the disorientation of students during the instruction. Also, in test questions, students on...

In this project we were given 80 images of cats and 80 images of dogs which was to be used as a training set to classify another set of 38 images containing cats and dogs. In this project four different methods were used for classification. The first method uses the Average and Laplacian filter followed by Linear Discriminant Analysis. The second method uses an k-nearest neighbors search with a...

The feline retroviruses, FeLV and FIV, today are well recognized for their ability to cause profound immune-suppressive disease in cats throughout the world. Clearly among the most complex infections affecting the cat, a retroviral infection demands an immune response that is robust and sustained if the infected cat is to survive long-term. Both innate immune responses (neutrophils, macrophages...

Although only recently discovered, feline adrenal disorders are becoming increasingly more recognized. Feline adrenal disorders include diseases such as hyperadrenocorticism (Cushing's syndrome) and hyperaldosteronism (Conn's syndrome). The clinical signs of feline hyperadrenocorticism, which include unregulated diabetes mellitus and severe skin atrophy, are unique to the cat. Other signs of fe...

BACKGROUND Little is known about the acceptance and usability of computerized adaptive tests (CATs) among patients with rheumatoid arthritis (RA). The main difference between completing a CAT and a traditional questionnaire concerns item presentation. CATs only provide one item at a time on the screen, and skipping forward or backward to review and change already given answers is often not poss...

Recently, the studies on Computerized Adaptive Testing are very popular in Chinese Mainland. The researchers care much about details of CAT, such as the psychometric models, the methods of estimating competency, termination rules, and item selection strategies. Several Cognitive Diagnosis CATs have been designed and evaluated. As to the perspectives, more attention should be paid to differentia...
