The paper is aimed at an investigation of the

features of a tubular-linear synchronous quasi-Halbach machine

(T-LSM) where the radially-magnetized PMs are substituted

by four equal segments with parallel magnetization. Such a

substitution is done in an attempt to improve the machine costeffectiveness

which makes it a viable candidate to equip freepiston

engine-based series hybrid propulsion systems. The study

is initiated an analytical formulation of the flux density spatial

The odometric model is simulated herein. We described the trajectory of such one odometric model, with the delta of the heading angle given as one parameter of the simulation. The iterations show that the trajectory is well in the continuity of the variations of the heading angle. Moreover the distance in X and in Y are shown for the vehicle to be driven in the trajectory of the odometric model.

The dataset consists of tracking data of over 23,000 vehicles travelling though five different roundabouts in Sydney, Australia. This data was collected by a vehicle outfitted with a ibeo.HAD Feature Fusion detection and tracking system. This system uses 6 ibeo LUX 4 beam, 25 Hz Lidar scanners to identify road users at a range of up to 200m, and has an on-board computer for classification and tracking, in real time.

The paper deals with fractional-slot permanent magnet synchronous machines

(FSPMSMs) equipped with phases made up of one coil parallel branches, with emphasis on their

faculty to reject the harmonic currents circulating in the loops yielded by the phase parallel branches.

These exhibit attractive potentialities, especially their enhanced open-circuit fault tolerance capability.

Furthermore, these topologies are suitably-adapted for low-voltage power supply that makes them

Car-hailing order data are a rich source to study the human mobility patterns, which could contribute to transporation planning and policy-making. In general, a orginal car-hailing order record includes information such as origin, destination, pick-up time, drop-off time, and travel distance. Beijing car-hailing order dataset stored the discretized order data at a traffic analysis zone(TAZ) scale, including the dataset for training and test.

we extract human trips from Call Records Detail data. Combining traffic analysis zone dataset, we map each trip record to the zones with the same origin zones and destination zones. After  this, we can obtain this dataset. This dataset stores the hourly number of departure and arrival trips in each traffic analysis zone.

Recognition of human activities is one of the most promising research areas in artificial intelligence. This has come along with the technological advancement in sensing technologies as well as the high demand for applications that are mobile, context-aware, and real-time. We have used a smart watch (Apple iWatch) to collect sensory data for 14 ADL activities (Activities of Daily Living).
