Title: Edison and St. Cyril: Seeking Common Ground. Presentation at Honorary Degree Award Ceremony<br/><br/>Authors: Friedman, Edward<br/><br/>Abstract: Rector Biolchev, Dean Mitev, and distinguished guests:I have been trying hard in recent months to avoid listening to pompouspronouncements about a new millennium. My instincts as a scientist and as amathematician tell me that this view of the passage of time is relative. Afterall, this is year 1420 in the Islamic calendar, thus placing us in the 15th century,while the Jewish calendar notes that the year is 5760 which is in the 58th century,not the 21st.Information Society for Enlightened Voting

Title: Information Society for Enlightened Voting<br/><br/>Authors: Passy, Solomon<br/><br/>Abstract: Among the millions of words uttered and written on the subject of democracy,Winston Churchill’s are among the most famous:“Democracy is the worst form of government except all those other forms thathave been tried from time to time.” [4] The occasion of the remark – it was madeon 11 November 1947, when the great wartime leader spoke for the oppositionin Britain’s House of Commons – is a reminder of how far the world has sincetravelled. Yet the passing of six decades notwithstanding, mankind is stillsubservient to the classical dogma embodied in Churchill’s phrase: that democracyis synonymous with universal suffrage.It was always open to question. But today, new and evolving technologiesenable us to discard it – not to abolish democracy (who would want to do that?),but to enrich democracy with more effective, more innovative and more moralforms of enlightened government across the world.Supporting the Bulgarian Young Talent in the Field of Informatics

Title: Supporting the Bulgarian Young Talent in the Field of Informatics<br/><br/>Authors: Asenova, Petya<br/><br/>Abstract: Dedicated to Edward Friedman on the occasion of his 80 th anniversaryIn this paper I share some impressions from my short communicationwith an exceptional person—Professor Edward Friedman fromStevens University of Technology, USA. Working in the field of integratingICT in education in the early 1990s, he launched several joint projects withBulgarian educators. The essentials of these activities were real projects inthe school. This idea was recently implemented at the university level as wellin the context of IT. I discuss this matter in the final sections of the paper.ACM Computing Classification System (1998): K.3.2.Combinatorial Computations on an Extension of a Problem by Pál Turán

Title: Combinatorial Computations on an Extension of a Problem by Pál Turán<br/><br/>Authors: Gaydarov, Petar; Delchev, Konstantin<br/><br/>Abstract: Turan’s problem asks what is the maximal distance from apolynomial to the set of all irreducible polynomials over Z.It turns out it is sufficient to consider the problem in the setting of F2.Even though it is conjectured that there exists an absolute constant C such thatthe distance L(f - g) <= C, the problem remains open. Thus it attracts differentapproaches, one of which belongs to Lee, Ruskey and Williams, who studywhat the probability is for a set of polynomials ‘resembling’ the irreduciblesto satisfy this conjecture. In the following article we strive to provide moreprecision and detail to their method, and propose a table with better numericresults.ACM Computing Classification System (1998): H.1.1.*This author is partially supported by the High School Students Institute ofMathematics and Informatics.Vision for the Engagement of the e-Facilitator in School in the Inspiring Science Education Environment

Title: On Learning in a Smart City Environment<br/><br/>Authors: Nikolov, Roumen; Shoikova, Elena; Krumova, Milena; Kovatcheva, Eugenia; Dimitrov, Velian; Chikalanov, Alexander<br/><br/>Abstract: Advances in technology in recent years have changed the learningbehaviours of learners and reshaped teaching methods and learningenvironments. This paper overviews a foundational framework and providesmodels for planning and implementing smart learning environments.Gartner’s 2015 Hype Cycle for Emerging Technologies identifies the computinginnovations such as Internet of Things, Advanced Analytics, Machine Learning,Wearables, etc., that organisations should monitor. Learners and students,being the future drivers of these industries, are the main human resource tofulfil the vacancies of these work forces. Constant improvements and re-evaluationof the curriculum has to be done regularly to keep the learners up-to-date inmeeting the requirements of these industries and corporations.Universities benefit from these thinking-outside-the-box practices by equippingstudents with work force experience that involves more hands-on tasks withreal-life infrastructures. The introduction is focused on analysis of emergingindustries and new types of jobs that require futurepersonnel to be well equipped to meet the expansion requirements of theseindustries and keep up with their development needs. Section 2 looks atthe future Internet domain landscape that comprises a great diversity oftechnology related topics involved in the implementation of Smart Learning Environments.The purpose of section 3 is to overview a foundational framework and majorconsiderations for the planning and implementation of smart learning environments,behind which is the convergence of advances and developments in social constructivism,psychology, and technology. Section 4 introduces the smart learning models whichare developed to reflect the dynamic knowledge conversion processes in technologyenabled smart learning environments.The last section presents a case study of a learning scenario entitled“Monitoring the environmental parameters in a Smart City” as an illustration ofexperimental learning on Internet of Things, which proofs the power of the FORGE(Forging Online Education through FIRE) FP7 project methodology and infrastructurefor building remote labs and delivering them to students.ACM Computing Classification System (1998): K.3.2.Educating Mathematics and Science Students in Urban USA and Sub-Saharan Africa - Lessons Learned and Future Challenges

Title: Educating Mathematics and Science Students in Urban USA and Sub-Saharan Africa - Lessons Learned and Future Challenges<br/><br/>Authors: Friedman, Edward<br/><br/>Abstract: This essay focuses on the challenges of implementing effectivemathematics and science programs in in secondary schools in urban Americaand Sub-Saharan Africa. A successful approach for meeting these challengesis considered which has first been introduced by the New Jersey Center forTeaching and Learning. This approach is based on maximizing the connectionsbetween mathematics and science, on developing an open-source software containingthe entire curriculum and loading it into a SMART board computer.Integral to the methodology used is the presentation of questionswith multiple choice answers. The technology implemented enables studentsto see the distribution of their answers (without seeing the correct one), andthe teacher engages them in discussion and debates about the merits of various answers.The success of the educating-the-educators model supported by the implementation ofthe SMART system in both urban America and in The Gambia provides a model that can bereplicated in diverse settings, and thus should be of interest to the world communityof mathematics and science educators.ACM Computing Classification System (1998): K.3.1.Extending the Class of Mathematical Problems Solvable in School

Title: Extending the Class of Mathematical Problems Solvable in School<br/><br/>Authors: Kenderov, Petar; Chehlarova, Toni<br/><br/>Abstract: The problems of practical importance which are considered in school todaynecessarily have to lead to a mathematical model that can be solved byschool mathematics knowledge. This includes systems of equations ofat most second degree, some simple trigonometry and/or some basic geometry.This restricts severely the class of such problems and conveys theimpression that mathematics is not applicable enough. We provide examples ofproblems related to practice which are difficult to solve by means of traditional schoolmathematics but are amenable for solving (at least with a certain precision)with the use of software systems dealing with mathematical problems.We also present the results of an experiment with such problems that were given toschool students participating in the second round of the competition“VIVA Mathematics with Computer”.ACM Computing Classification System (1998): K.3.1.Human Impact Factor in the Research and Development of Educational Software

LetDS = (U, C ∪ {d}) be a consistent decision table, we say that A ⊆ C is arelative reduct of DS if A contains a reduct of DS. Let s = <C ∪ {d} , F>be a relation schema on the attribute set C ∪ {d}, we say that A ⊆ C isa relative minimal set of the attribute d if A contains a minimal set of d.Let Qd be the family of all relative reducts of DS, and Pd be the family ofall relative minimal sets of the attribute d on s.We prove that the problem whether Qd ⊆ Pd is co-NP-complete.However, the problem whether Pd ⊆ Qd is in P .Lower Bounds on the Directed Sweepwidth of Planar Shapes
