High standard of walking environment in city centers and their transport hubs is important to stimulate urban activities. This requires urban planners to ensure improvements to pedestrian infrastructure as well as sign systems to assist destination search and route choice processes of users. This project covers a case study of a newly developed shopping and business complex next to a large tran...
From complex structures to complex processes: percolation theory applied to the formation of a city.
We investigate the morphology of the spatial pattern resulting from the division of land into the parcels that is observed in the centers of the cities, by analyzing the distribution function of the parcel areas. A simple model based on a two-dimensional bond percolation is employed to mimic the process of the formation of the city. The model reproduces the empirical distribution of the parcel ...
BACKGROUND Prior research has suggested that patients who travel out of their neighborhood for elective care from specialized medical centers may have better outcomes than local patients with the same illnesses who are treated at the same centers. We hypothesized that this phenomenon, often called "referral bias" or "distance bias," may also be evident in curative-intent cancer trials at specia...

We read with interest the recent study published in [1] regarding persistent levels of undernutrition in city like Chandigarh. The authors have concluded that the prevalence of underweight among under-five year old children remained almost stagnant in the last one decade from 51.6% (1997) to 50.4% (2007). We would like to point out that sampling frame and design of the published study pose limi...
Abstract Mobile information access and communication has become an important segment of modern life. At the same time, people wellbeing is taken into consideration for safe use technology. As per Bio-Initiative Report, existing standards are to be relooked proper healthy environment. Different countries adopting different criteria limit radiation power density within International Commission on...
the problem of designing a set of routes with minimum cost to serve a collection of customers with a fleet of vehicles is a fundamental challenge when the number of customers to be dropped or picked up is not known during the planning horizon. the purpose of this paper is to develop a vehicle routing problem (vrp) model that addresses stochastic simultaneous pickup and delivery in the urban pub...
