With the rapid development of VDSL (Very high-bit-rate Digital Subscriber Line) system, not all the tones have the same margin. In order to cope with the slowly-changing channel, Bit Swap is utilized to swap the tone pairs: the one has a high margin while the other one has a relatively low margin. Although the Bit Swap has been proposed before, there is no Bit Swap established on EOC and the proposed scheme also implements coarse and fine SNR margin tuning. The paper presents the architecture and process of Bit Swap based on EOC and also proposes the method to adjust the margin for tones calculated to be swapped. After thoroughly tested, the test results show that the proposed scheme functions well. Compared with the scheme without Bit Swap, it greatly improves the performance against crosstalk noise and can reduce the RS errors to zero.

Telecom Sector

The last few decades have witnessed a greater transition in the communication sector due to the unpre- cedented innovations in technology. On the one hand, the emergence of broadband has rejuvenated and strengthened the wireline sector by making use of the existing wireline infrastructure. On the other hand, it has created an intense competition among the service providers. The competition has propelled the service providers to look beyond the idea of providing service and has forced them to consider other factors like establishing customer loyalty which stems out of customer satisfaction and service quality. Thus, the study aims to analyze the interrelationship among the above-mentioned factors with respect to digital subscriber line (DSL) service offered by the incumbent wireline operator in Puducherry. The study has found that customer satisfaction plays an intervening role between service quality and customer loyalty.

Traditional Term

Abstract Pesantren are often associated with backwardness and traditionalism in everything: facilities, technology, learning methods, and even the curriculum. For now, it seems like the traditional term for pesantren is no longer relevant enough. The pace of movement in the era of renewal marked by the rapid development of technology has demanded pesantren to make adjustments. However, on the one hand, when viewed from the direction of change, the reform efforts pursued by pesantren are not to erase the old tradition, but merely to add something new so that the old tradition and conditions can be maintained while accepting the presence of a new one. On the other hand, the reform efforts undertaken by pesantren have implications for the fact that the typical values of the pesantren are fading away. Abstrak  Pesantren seringkali diasosiasikan dengan keterbelakangan dan tradisional dalam segala hal: fasilitas, teknologi, metode pembelajaran, dan bahkan kurikulumnya. Untuk saat ini, sepertinya istilah tradisional untuk pesantren, sudah tidak lagi cukup relevan. Laju gerak pembaharuan zaman yang ditandai dengan pesatnya perkembangan teknologi telah menuntut pesantren untuk melakukan penyesuaian diri. Kendatipun demikian, di satu sisi, jika dilihat dari arah perubahan, upaya pembaharuan yang ditempuh pesantren tidaklah untuk menghapus tradisi yang lama, tetapi sekadar menambah dengan sesuatu yang baru sehingga tradisi maupun kondisi yang lama bisa dipertahankan sambil menerima kehadiran yang baru. Di sisi yang lain, upaya pembaharuan yang dilakukan pesantren ternyata berimplikasi pada kenyataan akan semakin pudarnya nilai-nilai khas yang dimiliki oleh pesantren.

A fejlesztéspolitikában ma a „smart” címkével minden vonzóbb, eladhatóbb, a kifejezés sokszor a ’környezetbarát’ vagy ’fenntartható’ szinonimájaként is használatos. A városfejlesztésben az utóbbi idők egyik legfelkapottabb paradigmája, globális szintű versengést indítva mind a városok, mind az érdekelt vállalatok között a kölcsönösen hasznosnak vélt előnyök reményében. A szerzők egyrészt annak jártak utána, miért éppen most virágzott fel a smart city mint fejlesztési paradigma, és milyen tényezők indukálták gyors előretörését. Másrészt a nemzetközi példák bemutatásán keresztül arra a kérdésre keresik a választ, milyen társadalmi hatásokkal járnak ezek a fejlesztések, milyen kihívásokkal kell szembenézni a smart city fejlesztések kapcsán, és vajon a jövőben a fejlesztési szereplők képesek lesznek-e tanulni hibáikból, és tudatosan tervezni a hatások összességével. --- Do smart cities intensify social exclusion? In development policy everything seems to be more attractive and marketable when labelled ‘smart’; the expression is often used even as a synonym for ‘environmentally-friendly’ or ‘sustainable’. Considering urban development projects, smart city development is one of the most popular paradigms, triggering global competition between cities as well as the interested companies, both expecting mutual benefits from the co-operation. The article, on the one hand, tries to reveal, why the smart city paradigm has now started to thrive, and what factors played a part in its rapid development. On the other hand, through the presentation of international practices, the authors intend to answer what social impacts these developments have had, what challenges have the smart city developments met, and whether in the future the actors could learn from their mistakes and consciously take into account the complexity of impacts.

Insight Into

Due to the rapid development of digital media, the work of researchers in all scientific disciplines has dramatically changed. The objective of this chapter is to give a brief overview of digital tools that can be used for action or practice research in the context of seamless learning. It is the intention of the authors to, on the one hand, provide some initial orientation and deeper insight into the complex subject matter of digital science. On the other hand, researchers shall be equipped with a user guide that encourages them to try out various digital tools for searching, collecting, annotating, analyzing, visualizing, interpreting as well as publishing information. Owing to the dynamic nature of the issue under review this chapter will undoubtedly only offer a snapshot.
