Since testing is an expensive process, test selection has been proposed as a way to reduce such expense. A good selection of tests can be done using specification coverage functions. Model-based ioco theory, however, uses test suites which are not suitable for computing coverage because of interdependence of their test cases. We define a new test suite that overcomes such problems. Using such a...

We present a new multiagent model for the multiperiod portfolio selection problem. Individual agents receive a share of initial wealth, and follow an investment strategy that adjusts their portfolio as they observe movements of the market over time. The agents share their wealth at the end of the nal investment period. We show that a multiagent system can outperform a single agent that invests ...

User-to-user correlation is a fundamental component of Collaborative Filtering (CF) recommender systems. In user-to-user correlation the importance assigned to each single item rating can be adapted by using item dependent weights. In CF, the item ratings used to make a prediction play the role of features in classical instance-based learning. This paper focuses on item weighting and item selec...

Blinatumomab, the bispecific T cell engager, has been demonstrated as the most successful BsAb to date. Throughout the past decade, vector design has great importance for the expression of monoclonal antibody in Chinese hamster ovary (CHO) cells. It has been indicated that expression plasmids based on the elongation factor-1 alpha (EF-1 alpha) gene and DHFR selection marker can be highly effect...

several techniques exist to select and materialize a proper set of data in a suitable structure that manage the queries submitted to the online analytical processing systems. these techniques are called view management techniques, which consist of three research areas: 1) view selection to materialize, 2) query processing and rewriting using the materialized views, and 3) maintaining materializ...

The transportation sector already accounts for 14% of global greenhouse gas emissions. Therefore, controlling carbon emissions in the has become a top priority China and other countries around world. In addition to technological development clean energy transportation, most critical aspect globalization new industry market is optimization access routes. This paper will be based on road travel t...
