In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose range is between 0 and 3 is generated using chaotic logistic system. Then, the original image is divided into four subimages, and these four i...

The function of a Network Intrusion Detection System (NIDS) is to identify any misuse and abnormal behavior determined as an attack to a network segment or network host. The proposed concept is a pump-in-the-stack approach. This means, that NIDS-features are integrated into the network stack of our operating systems. Using the native stack is important, since this is the only place in our opera...

Background To this date, there has been no specific therapy proven to be effective for cyclic vomiting syndrome (CVS) in controlled trials. Multiple regimens have been proposed including: cyproheptadine, propranolol, amitriptyline, and phenobarbital. These medications are not without major side effects. The aim of this study was to describe the authors’ experience with hydroxyzine in children w...

Leakage power consumption of current CMOS technology is already a great challenge. ITRS projects that leakage power consumption may come to dominate total chip power consumption as the technology feature size shrinks. We propose a novel leakage reduction technique, named “sleepy stack,” which can be applied to general logic design. Our sleepy stack approach retains exact logic state – making it...

The adoption of all-electric vehicles (EVs) has grown rapidly in the transportation industry, particularly for urban parcel deliveries. However, limited driving range EVs and high investment cost establishing charging infrastructures are still holdbacks to routing these EVs. In this paper, we present vehicle problem a mixed fleet conventional (CVs) via intermediate depots as an alternative stra...

AIM This study aimed to evaluate the erythromycin efficacy in childhood cyclic vomiting syndrome. BACKGROUND Cyclic vomiting syndrome (CVS) is an unusual cause of episodic emesis in children and erythromycin is an effective treatment. PATIENTS AND METHODS In this prospective study, 301 patients with a final diagnosis of CVS enrolled in two separated groups. The first group received erythrom...
