Rates of species diversification vary widely across the tree of life and there is considerable interest in identifying organismal traits that correlate with rates of speciation and extinction. However, it has been challenging to develop methodological frameworks for testing hypotheses about trait-dependent diversification that are robust to phylogenetic pseudoreplication and to directionally bi...

In real-world applications, the test cost of data collection should not exceed a given budget. The problem of selecting an informative feature subset under this budget is referred to as feature selection with test cost constraints. Greedy heuristics are a natural and efficient method for this kind of combinatorial optimization problem. However, the recursive selection of locally optimal choices...

Due to increasing interest in validation and test generation tools, Telelogic AB, Malmm o, and the Institute for Telematics of the University of L ubeck have started a research and development project which aims at bringing new test generation facilities to the Tau tool set. For that purpose, a software component is developed which supports the automatic and semi-automatic generation of TTCN te...

The Estabrook-Wahlquist method for establishing the integrability of partial diierential equations is extended to semi-discrete (lattice) systems. If successful, the method construct the linear eigenvalue problem associated with the equation.

We present a successful collaboration of word embeddings and co-training to tackle in the most difficult test case of semantic role labeling: predicting out-of-domain and unseen semantic frames. Despite the fact that co-training is a successful traditional semi-supervised method, its application in SRL is very limited. In this work, co-training is used together with word embeddings to improve t...

Test-first strategy and code refactoring are both important features in Extreme Programming methodology. In the test-first strategy, test cases are designed before system implementation. If we want to improve certain non-functional attributes of the programs which are revised by refactoring, the original test cases may be broken or inefficient for testing the new programs. In this paper, we pro...

This study aimed to develop alternative English-speaking testing be used during the COVID-19 pandemic. A semi-direct speaking test for 4 graders was final product of this study. Cambridge curriculum with ESL framework (0837) formulate test. It designed using steps suggested by (Bachman and Palmer,1996). also has been reviewed an expert a trial group. asked each test-taker tell story provided pi...

The primary objective of this paper is to test informational efficiency of the A random walk test is performed for weak-form efficiency. In addition, day of the week effects are investigated to test semi-strong form efficiency. Empirical results verify that the İSE Composite Index is neither weak-form nor semi-strong form efficient although the nature and degree of inefficiency differ across pe...
