Connected Sociologies of Migration and Citizenship: An interview with Gurminder K Bhambra

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection

supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...

Dual Citizenship Allowance and Migration Flow

What effect does variation in dual citizenship policies of both sending and receiving societies have on bilateral migration flow? Employing a modified gravity model, we use a new dual citizenship database to examine the effects of allowance within 14 Organisation for Economic Co-Operation and Development (OECD) receiving states and more than 100 sending states between 1980 and 2006. We show tha...

An almost O(log k)-approximation for k-connected subgraphs

We consider two cases of the Survivable Network Design (SND) problem: given a complete graph Gn = (V,En) with costs on the edges and connectivity requirements {r(u, v) : u, v ∈ V }, find a minimum cost subgraph G of Gn that contains r(u, v) internally disjoint uv-paths for all u, v ∈ V . Our main result is an O (
