Monitoring every single email takes a lot of effort especially when the size of email transaction log is very large. This study proposed to find a wise option to monitor only the contents of important emails. Depth First Search algorithm, multi-digraph, email scoring model, WordNet, and Vector Space Model are used to create a model for filtering important emails and mining email contents. The findings showed that using email filtering module together with term enhancing module can help in reducing the processing time and keeping high precision and recall values of the system.

Recently as the demand of smart devices increases, the porting of embedded operating systems such as Google Android, Microsoft Windows Mobile, and Embedded Linux, becomes more important. Consequently, the importance of efficient, systematic porting is also raised. Generally, developers initiate embedded operating system porting from getting operating system source codes and materials. After they get source codes, they modify the source codes, and then they test them. To identify porting in detail, we investigated a small porting team which has fifteen members. In this team, each developer has done porting depending on his or her knowledge and experience. Therefore, we tried to find studies for efficient, systematic porting, but we couldn't find sufficient study results. This study aims to analyze porting process in a small organization. Also, we'll suggest productive a porting process and evaluate productivity of the new process through a case study.

With the tremendous volume of email messages, it is difficult to determine significant messages and users in an email system without knowing the message contents. This paper presents a simple and intuitive model to mine an email transactions log for significant messages and users. No use is made of NLP or semantic analysis. The model is based only on scoring messages and users from a graph-theoretic analysis of the communication pattern represented in the transaction log. Practical experiments indicate the potential of the model.

In this paper, we describe the concept and design of a novel visualization tool to aid in academic writing of English as a Second Language students. The tool makes use of theory in classroom discourse, WordNet API, and linguistics rules given by a linguistics expert, by analyzing English language essays for their linguistic bond counts and links within and between paragraphs. These linguistic indicators reveal the structure and flow of essays, clusters of main ideas, as well as incoherent sentences, which obstruct essay unity. The lack of essay unity is one of the most common writing errors of English as a Second Language learners. The output of the system is shown as several kinds of visualizations that provide writing feedback to users, as well as an autocorrect functionality to improve essay unity. Novice English learners may benefit greatly from this system.

In supply chains of petroleum industry, maintaining a proper inventory level for multiple petroleum products is a crucial issue. Basically, this chain has several elements like producer bases, consumer bases and terminals that are linked by means of a multi-modal transport network. These elements must cooperate to achieve the global goal of the system with a minimized cost. To achieve this goal, this paper presents a multiagent protocol for simultaneous negotiations based on the Contract-Net and the application of this in the chain aforementioned. As a result, this protocol proved to be very efficient to return a feasible solution in a low processing time.

In this paper, we investigate the outage performance of a dual-hop relaying systems with partial relay selection and feedback delay. The analysis considers the case of Rayleigh fading channels when the relaying station as well as the destination undergo mutually independent interfering signals. Particularly, we derive the cumulative distribution function (c.d.f.) of a new type of random variable involving sum of multiple independent exponential random variables, based on which, we present closed-form expressions for the exact outage probability of a fixed amplify-and-forward (AF) and decode-and-forward (DF) relaying protocols. Numerical results are provided to illustrate the joint effect of the delayed feedback and co-channel interference on the outage probability.

Most practical uses of Dynamic Bayesian Networks (DBNs) involve temporal inuences of the first order, i.e., inuences between neighboring time steps. This choice is a convenient approximation inuenced by the existence of efficient algorithms for first order models and limitations of available tools. We focus on the question whether constructing higher time-order models is worth the effort when the underlying system's memory goes beyond the current state. We present the results of an experiment with a series of DBN models monitoring woman's monthly cycle. We show that higher order models are significantly more accurate. However, we have also observed overfitting and a resulting decrease in accuracy when the time order chosen is too high.

This paper presents an analysis of simultaneous temperature and electrical parameters measurements in a three phase induction motor (TIM). The electrical parameters, namely voltage and current in the motor windings, were measured with Hall effect sensors and the temperature in the stator slots were monitored using fiber Bragg grating sensors (FBG). In the performed temperature analysis, two sets of sensors were used, containing four FBG in each fiber. Eight FBG sensors were uniformly distributed in the TIM stator. A special encapsulation of the sensor was elaborated to minimize mechanical disturbances in the fiber due to motor operation. Tests were performed with motor running at no load and with intentional voltage disturbances in the windings produced at every 15 minutes periods. It was observed that the temperature distribution is not uniform in the TIM stator either with or without a balanced voltage in the windings. A mean level increase of 0.5°C in temperature was registered in all of the sensors when there is a lack of balance in the voltage windings.
