The adoption of liquefied petroleum gas vehicles is strongly linked to the break-even distance at which they have the same costs as conventional cars, with very limited market penetration at break-even distances above 40,000 km. Hydrogen vehicles are predicted to have costs by 2030 that should give them a break-even distance of less than this critical level. It will be necessary to ensure that ...

In the present research a new viral systems optimization algorithm is developed to find the optimal number and position of wind turbines in large wind farms with the main objective of minimizing the cost per unit power produced from the wind park. The developed algorithm is applied to three well known problems in literature which are: 1) constant wind speed and unidirectional uniform wind, 2) c...

We consider problems of (new) station placement along (existing) railway tracks, so as to increase the number of users. We prove that, in spite of the NP-hardness for the general version, some interesting cases can be solved exactly by a suitable dynamic programming approach. For variants in which we also take into account existing connections between cities and railway tracks (streets, buses, ...

BACKGROUND Reduced gait speed is associated with falls, late-life disability, hospitalization/institutionalization and cardiovascular morbidity and mortality. Aging is also accompanied by a widening of pulse pressure (PP) that contributes to ventricular-vascular uncoupling. The purpose of this study was to test the hypothesis that PP is associated with long-distance gait speed in community-dwel...

Background: Mobile diabetes apps enable health care professionals (HCPs) to monitor patient progress, offer remote consultations, and allow more effective and informed treatment decisions between patients and HCPs. The OneTouch Reveal app aggregates data from a blood glucose meter and provides analytics to help patients and HCPs visualize glycemic trends and patterns, enabling more informed tre...

Authors have proposed a Novel Combined hybrid Architecture for various vehicular communication scenarios to the advancement of deployed Intelligent Transportation System (ITS). In our Scenario, the existing Dedicated Short Range Communication (DSRC) (IEEE 802.11 p) and Mobile WiMAX (IEEE 802.16 e) acts as an onboard Unit (OBU). As OBUs move between communication range, Vehicle exchange informat...

The lighting of the operating/surgical site depends on quality from overhead light source and reflection curtain. Light measurement operating table is very necessary because it generates that irradiated into cutting wound without dazzling surface so pathological conditions can be recognized must provide depth contrast anatomical relationships, to ensure this proper calibration method needed. Lo...
