摘要：This study is based on the combination of the following three primary pylons:(1)Literature;(2)Information—Communication Technology;(3)Utilization of digital means in the educational *** objective of this project is the utilization of the concordance with the help of AntConc application in the educational approach and specifically in the subject of Modern Greek *** the contribution of the above application,the educational process makes it more effective to comprehend a particularly hard kind of literature such as ***,Kyriakos Charalambides’1 poetry can be approached in both a different and an imaginative way,compared to the traditional textual way and as a result poetry can become more attractive for the *** project is focused on the poetic work of Kyriakos Charalambides,which consists of thirteen collections of *** reference text,which is included in the textbook“Modern Greek Texts”taught in the 2nd Grade of High School and is part of the curriculum,is a poem called“Sweet Preserves”(Charalambides,2000).The objective is to investigate whether in practice and particularly in the subject of Modern Greek literature,the above mentioned application can be utilized through the search of the literal type“soil”,through AntConc application for tracing the appearance frequency of this word and by extension the highlighting of this thematic motif in the poetic work of Kyriakos ***,in order that both the students’response(whether the objective was reached and the educational mediations were successful)and a certain level of awareness have been achieved,a questionnaire was distributed among the students and the students’answers were decoded through a specific type of software called SPSS so that the relevant outcomes were extracted.

摘要：The Activated Sludge Process(ASP) exhibits highly nonlinear properties. The design of an automatic control system that is robust against disturbance of inlet wastewater flow rate and has short process settling times is a challenging matter. The proposed control method is an I-P modi fied controller automatic control system with state variable feedback and control canonical form simulation diagram for the process. A more stable response is achieved with this type of modern control. Settling times of 0.48 days are achieved for the concentration of microorganisms,(reference value step increase of 50 mg·L-1) and 0.01 days for the concentration of oxygen(reference value step increase of 0.1 mg·L-1). Fluctuations of concentrations of oxygen and microorganisms after an inlet disturbance of5 × 103m3·d-1are small. Changes in the reference values of oxygen and microorganisms(increases by 10%, 20% and 30%) show satisfactory response of the system in all cases. Changes in the value of inlet wastewater flow rate disturbance(increases by 10%, 25%, 50% and 100%) are stabilized by the control system in short time. Maximum percent overshoot is also taken in consideration in all cases and the largest value is 25% which is acceptable. The proposed method with I-P controller is better for disturbance rejection and process settling times compared to the same method using PI controller. This method can substitute optimal control systems in ASP.
