In the Vehicle Routing Problem with Time Windows, a set of customers are served by a eet of vehicles of limited capacity, initially located at a central depot. Each customer provides a period of time in which they require service, which may consist of repair work or loading/unloading the vehicle. The objective is to nd tours for the vehicles, such that each customer is served in its time window...

background: this study was undertaken to compare the outcome in patients with moderate to severe ischemic mitral regurgitation (imr) undergoing coronary artery bypass grafting (cabg) with either mitral valve repair or mitral valve replacement. methods: between march 2002 and february 2005, 49 consecutive patients (mean age: 62.84±8.42 years; mean euroscore: 10.03±3.12) with coronary artery dise...

vehicle detection and classification of vehicles play an important role in decision making for the purpose of traffic control and management.this paper presents novel approach of automating detecting and counting vehicles for traffic monitoring through the usage of background subtraction and morphological operators. We present adaptive background subtraction that is compatible with weather and ...

background: exposure to ionizing radiation is known to induce oxidative stress followed by damage to critical biomolecules like lipids, proteins and dna through radiolysis of cellular water. since radiation has been widely used as an important tool in therapy of cancer, the detailed investigation regarding the dna damage and repair kinetics would help to predict the radiation sensitivity of cel...

the intelligent transportation system (its) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. this system consists of many fixed and mobile nodes (vehicles, trains, vessels, air planes), wireless and wired telecommunication technologies to exchange information between mobile nodes or betwee...

A pothole is an open crack developed on roads owing to varied climatic situations and exposure heavy-load trucks. Potholes are acting as one of the major causes accidents economic loss in repair vehicles. Hence this paper proposes a detection system that assists drivers avoiding potholes road by providing prior warnings using YOLOV7 machine learning technique. The warning can be like buzzer whi...

the renewable energy sources and plug-in electric vehicles (pevs) are becoming very popular because of the combination of high fuel costs and concerns about emission issues. this paper presents modelling and control of a building integrated fuel cell and plug-in electric vehicles (bifc-pev) in smart distribution systems. in bifc-pev system, conventional building elements could be replaced by sp...

nowadays, the use of small vehicles is spreading among urban areas and one sort of these vehicles are three-wheeled vehicles (twvs) which can be competitive with four-wheeled urban vehicles (fwvs) in aspects such as smallness, simple manufacturing, and low tire rolling resistance, fuel consumption and so on. the most critical instability associated with twvs is the roll over. in this paper a ti...

distribution is one of the most important topics in industrial engineering and logistics and supply chain that all organizations are dealing with it in the upper echelons and are looking for the optimum distribution of resources and equipment among the echelon. generally, it is seen that organizations cannot have a good distribution if there is not a suitable criterion for the distribution of e...

Using electric vehicles, in addition to decreasing the environmental concerns, can play an important role in decreasing the peak and filling the off-peaks of the daily load characteristics. In other words, in smart grids' infrastructure, the load characteristics can be improved by scheduling the charge and discharge process of electric vehicles. In smart grids, the customers are instantaneously...
