in 1974, the world health organization (who) established the expanded program on immunization (epi) to ensure that all children have access to routinely recommended vaccines. since then, global coverage with the four core vaccines (bacille calmette guérin vaccine [for protection against tuberculosis], diphtheria-tetanus-pertussis vaccine [dtp], polio vaccine, and measles vaccine) has increased ...

It is part of the traditional lore of genetic algorithms that low mutation rates lead to efficient search of the solution space, while high mutation rates result in diffusion of search effort and premature extinction of favorable schemata in the population. We argue that the optimal mutation rate depends strongly on the choice of encoding, and that problems requiring nonbinary encodings may ben...

Introduction: Coverage of bone grafts is very important in reconstructive surgery. In edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. Here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for up...

From practical and theoretical viewpoints, performance analysis of communication systems by using information-theoretic results is important. In this paper, based on our previous work on Multiple Access Channel (MAC) and Multiple Access Relay Channel (MARC), we analyze the impact of a relay on the fundamental wireless communications concept, i.e., coverage region of MARC, as a basic model for u...

Vaccination considered as one of the most cost-effective health interventions worldwide  through prevention and control of many serious childhood diseases (1). It is estimated  global coverage of  Dose 3 of Diphtheria, Tetanus, and Pertussis (DTP3)among children one year old has been 86% in 2014 (by range from 77% to 96%  in African Region and Western Pacific Region; respectively) (2). Globally...

The majority of case-based planning systems consider an infinite case memory to store their cases. However, the size of the case memory is limited and it can become a barrier for case-based systems efficiency when it is full. This paper presents a method that refines and abstracts cases in order to release memory space for a new case. However, in some situations, some cases must be chosen to be...

The purpose of this study is to develop a design for maximum area drone coverage in post-disaster flood situation. When it comes covering disaster-region monitoring and detection the extent damage losses, suitable technically balanced approach vital achieving best solution while affected area. Therefore, mathematical optimisation model proposed effectively capture images impacted region. partic...
