background  & aim: case-crossover  studies are the case-control  version of crossover studies. in these studies, cases and controls are the same subjects. the term crossover is applied for designs that all subjects pass through both treatment (exposure) and placebo (non-exposure) phases. in fact they are  crossover  of  subjects  between  periods  of  exposure  and  non-exposure.  this  design ...

In order to achieve the maximum flexibility in adaptation to ever changing customer’s expectations in customer relationship management, appropriate measures of customer behavior should be continually monitored. To this end, control charts adjusted for buyer’s/visitor’s prior intention to repurchase or visit again are suitable means taking into account the heterogeneity across customers. In the ...

Cystic Hygroma is a well-recognized lesion in paediatric patients but it is very rare in adults. We report here a case of Cervical Cystic Hygroma in a 45 yr old male. The reasons to present this case are 1) Its rarity in adults 2) Unusual age of presentation 3) Simulates various benign and malignant lesions at this site 4) Is a diagnostic challenge and 5) Role of histology for definitive postop...

Although widely used, traditional use case modeling does not provide explicit means which could be easily used for capturing and testing behavior compliance of the entities involved in a particular use case model. Specifically, a use case model (a set of use cases) related to a system under design provides neither an explicit abstraction to capture the “whole picture” of the behavior of the sys...

embedded systems are becoming a suggestive target for code injection attacks in recent years. software protection mechanisms in general computers are not usually applicable in embedded systems as they come with limited resources like memory and processor. in this paper we investigate side channel characteristics of embedded systems and their usability in code injection attack detection. the arc...

small cell carcinoma of the urinary bladder (sccub) is an extremely rare bladder malignancy characterized by an aggressive clinical behavior. so, it is important to diagnose this high grade disease by urinary cytology. we report a case of sccub in an old man with chronic lymphocytic leukemia (cll) in remission, while bladder tumor was diagnosed by cytology. with this article, we aimed to review...

This research examines a hybrid planner for a real-world mobile robot delivering messages in an office environment. The overall project, RUPART, uses "unified CBR" to combine behavior-based control with high-level case-based planning, using a single similarity metric to retrieve both behavior cases and plan cases. This paper focuses on case-based reasoning for behavior cases. Each behavior case...

In a use case model of an entity, multiple use cases are used to describe its behavior, leaving the behavior specification scattered across different use cases with no specific way to get a “whole picture” of the entity’s behavior. To address the issue, we introduced in [16] a simple formal model Generic UC View which also articulates four consistency issues capturing key requirements on behavi...
