Refurbishment work involves improvement, adaptation, upgrading, renovation, modernization, retrofit, and repair of existing housing. With limited land usage and being aware of sustainability, the refurbishment market has faced increasing needs worldwide in the last decade. Refurbishment projects on existing housing, however, have complex and uncertain characteristics that are recognized to be m...

BACKGROUND Community-based care, underpinned by relevant primary care research, is an important component of the global fight against non-communicable diseases. The International Primary Care Research Group's (IPCRG's) Research Needs Statement identified 145 research questions within five domains (asthma, rhinitis, chronic obstructive pulmonary disease (COPD), smoking, respiratory infections)...

The availability of various koi pond pump products is marketed with kinds, types, and advantages. This diversity makes it difficult for business owners to determine a product that suits their needs. consideration the in question form an electric submersible or ESP. One method can be used selection AHP (Analytical Hierarchy Process) method. study uses assisted by expert choice software. From res...

Decreasing breast cancer mortality represents a high priority for patients and their health care providers. Assessment of individual risk combined with discussion of risks and benefits of screening is essential in assisting patients in making their screening decisions. This article reviews the literature in order to provide primary care providers information regarding risk assessment, controver...

countries around the world are experiencing an ever-increasing need to make choices in investments in health and healthcare. this makes it incumbent upon them to have formal processes in place to optimize the legitimacy of eventual decisions. there is now growing experience among countries of the implementation of stakeholder participation, and a developing convergence of methods to support dec...

This paper is concerned with the stability of a preemptive repeat priority queueing system with multiple types of customers and customer transfers between queues. Using the mean-drift method and matrix-analytic methods, simple conditions for the queueing system to be stable or instable are found. The conditions indicate that system stability depends only on the service rate of customers of the ...

We obtain an essentially optimal tradeoff between the amortized cost of the three basic priority queue operations insert, delete and find-min in the comparison model. More specifically, we show that A(find-min) = Ω ( n (2 + )A(insert)+A(delete) )

We study MX/G/1 nonpreemptive and preemptive-resume priority queues with/without vacations under random order of service (ROS) discipline within each class. By considering the conditional waiting times given the states of the system, which an arbitrary message observes upon arrival, we derive the Laplace-Stieltjes transforms of the waiting time distributions and explicitly obtain the first two ...

A new priority queue structure is introduced, for which the amortized time to insert a new element isO(1) while that for the minimumextraction is O(logK). K is the average, taken over all the deleted elements x, of the number of elements that are inserted during the lifespan of x and are still in the heap when x is removed. Several applications of our structure are mentioned.
