among numerous np-hard problems, the traveling salesman problem (tsp) has been one of the most explored, yet unknown one. even a minor modification changes the problem’s status, calling for a different solution. the generalized traveling salesman problem (gtsp)expands the tsp to a much more complicated form, replacing single nodes with a group or cluster of nodes, where the objective is to fi...

the suspension system of a vehicle is one of the most important parts which is involved in the process of vehicle designing. when a vehicle suspension system is designed, the evaluation of its performance against the road disturbances such as shocks and bumps are very important. the most commonly used systems consist of four hydraulic jacks with mobility in vertical line with low speed and low ...

This document describes how the currently specified IPv6 flow label can be used to enhance layer 3/4 (L3/4) load distribution and balancing for large server farms.

In 2007, the National Children's Center for Rural and Agricultural Health and Safety (NCCRAHS) published Agritourism Health and Safety Guidelines for Children to provide helpful recommendations for protecting the health and safety of children visiting agritourism farms. Supplement A: Policies and Procedures Guide and Supplement B: Worksite Guide were subsequently published in 2009 and provided ...

That we are living in an age of information and knowledge explosion is an accepted cliché. Formal and informal data, information and knowledge are available to individuals and organizations in both structured and unstructured formats leading to information overload, concerns about data accessibility, discussions of the role of metadata, content farms, return on investment in both the creation a...

This paper aims to construct an empirical model for the analysis of two principal simultaneous decisions of farm operators: participation in the off-farm labor market, and the amount of resources to invest in farm capital. We first develop a theoretical model analyzing the effects of exogenous shocks on farmers’ decisions. Then, we estimate jointly a multinomial probit model of farmers’ off-far...

In the spring and summer of 2001, 47 fathers, 48 mothers and 117 children of Iowa farm and non-farm households were recruited to participate in a study investigating take-home pesticide exposure. On two occasions approximately 1 month apart, urine samples from each participant and dust samples from various rooms were collected from each household and were analyzed for atrazine, metolachlor, gly...

In this paper we analytically derive the sojourn time of a user accessing an online IPTV recording service. Basically, the system consists of a server (or server farm) and the bandwidth at which a user can download recorded files depends on the number of other concurrently downloading users. In particular, we consider both cases, one in which the user’s download speed is limited by his own acce...

In order obtain suitable and effective farm machinery performance besides higher crop yield, on time farm machinery field operations are essential. Farm tractors are important machines that used for soil tillage, crop planting and protection. It is even used for harvesting crops in some areas. Thus, any failure in farm tractors influences the series of field operations. Farm managers are usuall...
