In this paper we propose a model for the problem of designing a rapid transit network which includes transfers. Our objective is to maximize the number of expected users in the transit network taking limited budgets into consideration. Additionally, the existing competition between private and public modes is assumed when the generalized cost for the user trips is calculated. Some computational...

This paper describes the work done in Renmin University of China for the Federated Web Search Track of TREC 2014. We participated in the resource selection task. We used the LDA topic modeling approach to select potentially relevant resources for a given query. The initial results are promising.

A unified approach is proposed to support the rapid development of editors such as pen-based structured diagrams. This approach uses Constraint Multiset Grammars to describe the context or positional relationships among handwritten strokes and other objects. The resulting description can then be used to interpret ambiguous results of pattern matching techniques. We have implemented this approac...

We discuss the string theory on AdS3. In the first half of this talk, we review the SL(2, R) and the SL(2, C)/SU(2) WZW models which describe the strings on the Lorentzian and Euclidean AdS3 without RR backgrounds, respectively. An emphasis is put on the fundamental issues such as the unitarity, the modular invariance and the closure of the OPE. In the second half, we discuss some attempts at c...

Es wird ein Verfahren zur Herstellung patientenspezifischer Annuloplastieringe vorgestellt. Der Mitralklappenannulus wird aus Computertomographiebildern modelliert. Eine optimale Ringgeometrie wird interaktiv erstellt. Die Ringe werden mittels Selective Laser Melting aus einer Titanlegierung hergestellt. Im Tierversuch wurde die Machbarkeit des Verfahrens überprüft. Mit patientenspezifisch gefo...

Preparation for entry into the information professions has always been through a combination of academic study and practical training. Broadly speaking there is probably general agreement about the knowledge and understanding which the new entrant to the profession needs to acquire. There is less clarity regarding the skills which are required if s/he is to function effectively as an informatio...

Estimating Recovery Rate and Recovery Amount has taken a more importance in consumer credit because of both the new Basel Accord regulation and the increase in number of defaulters due to the recession. We examine whether it is better to estimate Recovery Rate (RR) or Recovery amounts. We use linear regression and survival analysis models to model Recovery rate and Recovery amount, thus to pred...
