background: the number of interventional cardiology (ic) procedures has increased rapidly. coronary angiography (ca) and percutaneous transluminal coronary angioplasty (ptca) are now widely performed as a matter of routine, and they are considered safe procedures for experienced cardiologists. however, it is also known that these procedures are associated with high radiation doses due to long f...

Given a coloring f : V (G) → IN of graph G and any subgraph H ⊂ G we define fs(H) = ∑ v∈V (H) f(v). In particular, we denote fs(G) by S(f). The coloring f is called an ICcoloring if for any integer k ∈ [1, S(f)] there is a connected subgraph H ⊂ G such that fs(H) = k. Also, we define the IC-index of G to be M(G) = max{ S(f) : f is an IC-coloring of G }. In this paper we examine some well-known ...

Using the idea of ic-open sets, we introduce and investigate topological qualities an ic-closure, ic-interior, ic-limit points, ic-derived, ic-border, ic-frontier, ic-exterior a set. Introduce concepts "ic-continuous mappings," "ic-open "ic-irresolute "ic-totally continuous "ic-homeomorphism," then look into some properties these mappings

More than a decade of research in the field of thermal, motion, vibration and electromagnetic radiation energy harvesting has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC–DC conversion are becoming able to efficiently convert the power from these energy harvesters. This paper summarizes recent energy harvesting results and their pow...

This paper describes the development and preliminary testing of a robotic device to facilitate minimally invasive beating-heart intrapericardial interventions. We propose the concept of a subxiphoid-inserted mobile robot (HeartLander) with the ability to adhere to the epicardium, navigate to any location, and administer therapy under physician control. As compared to current laparoscopic cardia...

Intellectual capital (IC) is organizational intangible asset which is frequently associated with performance. IC is commonly categorized into three core components: human capital, structural capital and relational capital. This study takes a step further in the evolution of the IC model for the hotel industry and divides relationship capital into two categories: End customer- relationship capit...
