A systematic approach to the analysis and design of a bi-directional Cûk converter for the cell voltage balancing control of a series-connected lithium-ion battery string is presented in this paper. The proposed individual cell equalizers (ICE) are designed to operate at discontinuous-capacitor-voltage mode (DCVM) to achieve the zero-voltage switching (ZVS) for reducing the switching loss of th...

In this paper, we will explore machine comprehension in Stanford Question and Answering Dataset using ensembled deep recurrent neural networks with bi-directional attention flow. Given a context paragraph, we attempt to answer a query related to the context paragraph. This requires use to not only generate knowledge representation for each question and paragraph, but also create mechanisms that...

This paper presents a new multi-function conversion technique for vehicle-to-grid (V2G) applications. The proposed bi-directional charger can achieve three functions, including EV battery charging, grid-connection and reactive compensation, which are keys for energy management of the grid. With the proposed multi-function technology, the bi-directional charger will benefit both the grid and ele...

Although underlay networks mitigate the dual problems of spectrum congestion and spectrum under-utilization, the bi-directional (primary-to-secondary and secondaryto-primary) interference issues must be addressed to improve their reliability, coverage and capacity. To address these problems, this thesis investigates beamforming and two-way relaying. Specifically, the two underlay configurations...

The free boundary model of diffusion-induced grain boundary motion derived in Cahn et al. [3], Fife et al. [6] and Cahn & Penrose [4] is extended, in the case of thin metallic films, to account for bidirectional motion, together with the appearance of S-shapes and double seam configurations. These are often observed in the laboratory. Computer simulations based on the extended model are given t...

We study strategies of approximate pattern matching that exploit bidirectional text indexes, extending and generalizing ideas of [6]. We introduce a formalism, called search schemes, to specify search strategies of this type, then develop a probabilistic measure for the efficiency of a search scheme, prove several combinatorial results on efficient search schemes, and finally, provide experimen...

A multihop, wavelength division multiplex (WDM)based network, CayleyNet, is proposed for the realization of terabit lightwave networks. CayleyNets are attractive virtual topologies because they support the largest number of nodes for four-neighbor connection in n range of diameters. In general, CayleyNets are bi-directional and there are N = p x k nodes, where p is a prime and k is a factor of ...

We present a monadic treatment of symmetric state-based bidirectional transformations, and show how it arises naturally from the well-known asymmetric lens-based account. We introduce two presentations of a concept we dub the “entangled” state monad, and prove their equivalence. As a step towards a unifying account of bidirectionality in general, we exhibit existing classes of statebased approa...

ing away from the effect of the phonological rules mentioned, the template of Nicobarese reduplication is a syllable PuC. A standard copyand-association analysis involving a prespecified CVC template will have to somehow insure that the coda segment in a form like cim ends up in coda position. Since prelinked segments, if used at all, must be interpreted conditionally, we are faced with the cho...

Effective route planning for battery electric commercial vehicle (ECV) fleets has to take into account their limited autonomy and the possibility of visiting recharging stations during the course of a route. In this paper, we consider four variants of the electric vehicle-routing problem with time windows: (i) at most a single recharge per route is allowed, and batteries are fully recharged on ...
