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. This substitution is done in an attempt to improve the machine cost-effectiveness which makes it a viable candidate to equip free-piston engine-based series hybrid propulsion systems. The study is initiated by an analytical formulation of the air gap flux density considering (i) the case of the conventional quasi-Halbach T-LSM and (ii) the case of the segmented pole one.

Thiswork dealswith fractional-slot permanent
magnet synchronous machines (FSPMSMs) equipped with
phasesmade up of one coil parallel branches. These exhibit
attractive potentialities, especially their enhanced opencircuit
fault tolerance capability. Furthermore, these topologies
are suitably-adapted for low-voltage power supply that
makes them viable candidates for possible integration in
the 42V automotive technology. This potentiality is further
highlighted in battery electric vehicleswhere the passenger

The paper is aimed at a class of fractionalslot
permanentmagnet synchronousmachines (FSPMSMs)
equipped with phases made up of one coil parallel
branches, with emphasis on their potential to reject the
harmonic currents circulating in the loops created by the
parallel branches. Following the identification and topological
characterization of this class of machines in Part 1,
the star of slots approach is extended to the analysis of
the back-EMF harmonic content. This makes it possible the

The project is conceptualized to 'Geo Web-Based Facility Mapping for Zone-2 in Greater Visakhapatnam Municipal Corporation- GVMC in Visakhapatnam, India'. The main objective is to share the spatial data to the public to help them find the information about the nearest Hospital, ATM, Educational institutions, petrol filling stations, and supermarkets by providing both web map services and web coverage services using QGIS Cloud.

The paper is aimed at an investigation of the effects of the mover eccentricity on the PM eddy current loss of tubular-linear synchronous machines (T-LSMs) equipped with quasi-Halbach magnetized PMs. The study is initiated by an analytical prediction of the no-load spatial repartition of the flux density taking into account the non-coaxiality of the mover and stator, and its validation by a 3D finite element analysis (FEA). Then a special attention is paid to an analytical formulation of the PM eddy current loss in presence of eccentricity.

The dataset consists of vessel tracking data in the form of AIS observations in the Baltic Sea during years 2017-19. The AIS observations have been enriched with vessel metadata such as power, max speed and draft. The data has been collected for master’s thesis work and the data has been splitter into training and validation sets. The AIS observations do not cover all months of the collection period.

Along with the increasing use of unmanned aerial vehicles (UAVs), large volumes of aerial videos have been produced. It is unrealistic for humans to screen such big data and understand their contents. Hence methodological research on the automatic understanding of UAV videos is of paramount importance.
