The performance and applicability of a fault-proneness prediction model built based on internal quality measures computed on classes of one or more software systems and applied to classes from a different software system may be heavily influenced by several factors. These factors are related to the specific characteristics of the software system an...

In this work we presented the following clustering algorithms: k-means, k-medoids, hierarchical and DBSCAN. We presented theoretical background behind the above approaches as well as practical issues related to performing clustering. Three examples were supplied to illustrate the mechanism of action of selected algorithms and to present differences...

The performance of a communication system is mainly depending on channel between the receiver and the transmitter in the system. Therefore, the most important thing for communication is the channel which is affected by parameters such as noise, fading, shadowing, and interference. These effects complicate for the receiver to obtain the transmitted...

As everyone knows, the black soil of Heilongjiang bred rice is famous in the world. How to use networking technology to detection the growth environment of Heilongjiang rice, and expands it to the local planting environment to our country is the most important topic. However, the growth environment of rice is complex. In current research, some impo...

... Constructivism states apprentices do not reproduce the knowledge, but they mentally reconstruct it by associating each new concept with existing ones [7]. We derived from [7] six steps for a recommended teaching-learning process that are explained in [27]. The following list briefly describes each step. ...

Metaphors of ordinary concepts are intensively used in computer science for naming abstract concepts and for designing users interfaces. Metaphors are mappings from a source domain (e.g., a stream) to a target domain (e.g., a sequence of bytes). Typically computing phenomena are explained using incoherent discourses at the source domain, formed by metaphors taken from a diversity of origins. Nonetheless, versatility of metaphors allows for the creation of coherent discourses in the origin domain that map the target computing discourse, and we call them allegories. The limited number of existing studies about this topic has compared only textual allegories, visual allegories, and the traditional unconnected metaphors. Although their findings are heterogeneous, equal effectiveness is the most frequent empirical result between these three types of metaphors. Furthermore, we have not found any study about oral allegories, in spite of oral being the most used modality for metaphors in computer science education. This article experimentally compares the effects of oral allegories and oral metaphors on a complex problem‐solving task. As in previous studies, our results did not find any significant differences on support or detriment of oral allegories. Our results support new metaphor theories posing that the context significantly influences the metaphors’ efficacy, and encourages future research about the interaction between context and allegories.
