We discuss routing algorithms for wireless networks with the goal of increasing the network and node life. Recently, a cost aware metric based on remaining battery power at nodes was proposed and verified for non-localized shortest-cost routing algorithms, assuming constant transmission power. Two metrics where transmission power depends on distance between nodes were also recently proposed. We...

This paper investigates the economic consequences of a haulage company replacing its line-haul diesel trucks with battery-electric ones. It also examines how large truck batteries should be, whether companies use public fast chargers to complement their own, and have potential be profitable. The extra cost losing payload capacity is estimated there an investigation charge-point operator meet pe...

Abstract Comparing two distributions plays important role in many problems. The traditional minimum cost flow problem has been utilized as a distance measure between two distributions (transportation problem) such as the earth mover’ distance (EMD). If the distributions have b number of bins, the cost matrix is b × b square matrix. While generic algorithms such as Simplex method to compute the ...

The K-Closest-Pairs Query (K-CPQ), a type of distance join in spatial databases, discovers the K pairs of objects formed from two different datasets with the K smallest distances. Recently, branch-and-bound algorithms based on R-trees have been developed in order to answer K-CPQs efficiently. For query optimization purposes, analytical models are needed to estimate the processing cost of a spec...

This paper aims to show the effect of macrocellular network densification on the capacity, energy and cost efficiency. The presented results are based on radio propagation simulations that consider macrocellular network with different inter-site distances, i.e. different site densities, and also take into account the presence of indoor receiver points by varying outdoor and indoor receiver dist...

Background: Osteoarthritis is a common chronic disease of the musculoskeletal system in older adults. Aim: This study aimed to compare the effects of in-person and distance exercise training on the outcomes of knee injury and osteoarthritis among the elderly with limited literacy. Method: In this two-group randomized clinical trial with a pretest-posttest design, 60 elderly patients with knee i...
