The selection of the most acceptable architecture of e-services system is very important issue. One and the same e-service can be designed using different alternative architectures. Each system has different execution indices that are very important for the e-services clients and providers. This article shows solutions for compromise or the most acceptable selection of the architecture of e-ser...

In industrial large-scale search systems, such as Taobao.com search for commodities, the quality of the ranking result is getting continually improved by introducing more factors from complex procedures, e.g., deep neural networks for extracting image factors. Meanwhile, the increasing of the factors demands more computation resource and raises the system response latency. It has been observed ...

Learning and instruction can be enhanced with the information provided from assessment. Computerized adaptive testing is an effective mode of e-testing as it can be operated in a continual and dynamic mode. It can also cater for individual needs by providing tailor-made tests. In this paper, we will examine a new item selection approach which would allow more flexibility in balancing the two co...

The European Global Product Realization (E-GPR) project represents the main practical part of the E-GPR course organized by 3 European universities: the Swiss Federal Institute of Technology of Lausanne, the Technical University of Delft and the University of Ljubljana. It is defined in collaboration with the industrial partner(s) of the E-GPR course and consists of developing a global product ...

Three new models for the settlement selection problem are discussed and compared with the existing models. The new models determine a ranking rather than a selection, which has advantages both from the e ciency and the geographic correctness point of view. We give gures of selections based on six di erent models, and explain how the models can be implemented e ciently.

The present study was conducted among the academic librarians under Mumbai University to ascertain the major challenges faced by them while selecting and acquiring e-resources. The survey revealed that the college libraries‘ e-collection is dominated by e-journals. It is found that the librarians use multiple tools to select the e-resources. Apparently, the selection of e-resources depend upon ...

Research comparing centralized and decentralized coordination schemes is often contradictory. This paper focuses on this issue in the context of agent-based marketplaces. Specifically, we use a computational approach to study the trade off between imperfect decision-making by the central coordinating agent (the central authority) and the imperfect coordination among decentralized seller agents....

E prover is a state-of-the-art theorem prover for first-order logic with equality. E prover is built around a saturation loop, where new clauses are derived by inference rules from previously derived clauses. Selection of clauses for the inference provides the main source of nondeterminism and an important choice-point of the loop where the right choice can dramatically influence the proof sear...

Engineering heterologous nucleoside kinases inside E. coli is a difficult process due to the integral role nucleosides play in cell division and transcription. Nucleoside analogs are used in many kinase screens that depend on cellular metabolization of the analogs. However, metabolic activation of these analogs can be toxic through disruptions of DNA replication and transcription because of the...
