Hiện nay, việc sử dụng xe hybrid đang ngày càng phổ biến tại Việt Nam cũng như trên toàn thế giới. Việc nghiên cứu để làm chủ công nghệ về là một vấn đề có tính thực tiễn cao. Trong đó, nguồn động lực của tài quan trọng hàng đầu. Các bao gồm: cơ đốt trong, điện. Nội dung bài báo trình bày xác định phương pháp phối hợp hybrid, toán các thông số Sau và trong thường được thiết lập mô phỏng phần mề...

Transit network simulation models are often used for performance and retrospective analysis of urban rail systems, taking advantage the availability extensive automated fare collection (AFC) vehicle location (AVL) data. Important inputs to such models, in addition origin-destination flows, include passenger path choices train capacity. Train capacity, which has been overlooked literature, is an...

A 59-year-old woman had been treated at another hospital for unstable angina for 5 days. One day after discharge , she returned with prolonged chest pain, and an electrocardiogram was recorded (Figure 1). The most notable features of the electrocardiogram are ST and T changes in leads V 1 through V 4. Superficially, these changes suggest a left anterior descending lesion with anterior subendoca...

Automatic vehicle location (AVL) data can be used for a variety of operational and planning purposes at a transit agency. One possible application is for passenger itinerary planning, where the passenger seeks to go from an origin to a destination in some “optimal” way. The AVL data give actual vehicle arrival and departure times, which in turn can give more robust itineraries to passengers. Th...

Relevant path planning using public transportation is limited by reliability of the transportation network. In some cases it turns out that we can plan paths with respect to expected delays and hereby improve reliability of the resulting path. In our work we focus on prediction of the delays in public transportation systems. For this purpose we use data from vehicle tracking systems used by tra...
