Each semester, the seminar takes place in two different ways: once as a block seminar during the semester break and once in the course of the semester. Both seminars share the same contents and differ only in their duration. In the context of the seminar, each student individually works on a relevant topic in the domain of computer networks supervised by one or more advisors. Advisors are staff members working at the Chair of Network Architectures and Services at the Technical University of Munich. As part of the seminar, the students write a scientific paper about their topic and afterwards present the results to the other course participants. To improve the quality of the papers we conduct a peer review process in which each paper is reviewed by at least two other seminar participants and the advisors. Among all participants of each seminar we award one with the Best Paper Award. For this semester the arwards where given to Bernhard Vorhofer with the paper Extending ZMap: Round-Trip Time Measurement via ICMP and TCP and Simon Bachmeier with the paper Network Simulation with OMNet++ . Some of the talks were recorded and published on our media portal https://media.net.in.tum.de. We hope that you appreciate the contributions of these seminars.

While most of the detection techniques just rely on structural information, many code smells are intrinsically characterized by how code elements change over time. In this paper, we propose Historical Information for Smell deTection (HIST), an approach exploiting change history information to detect instances of five different code smells, namely Divergent Change, Shotgun Surgery, Parallel Inheritance, Blob, and Feature Envy. We evaluate HIST in two empirical studies.

  • Merger Policy in Digital Markets: an Ex Post Assessment 3 Study Is to Undertake a Less Common Form of Ex Post Assessment
    Journal of Competition Law & Economics, 00(00), 1–46 doi: 10.1093/joclec/nhaa020 MERGER POLICY IN DIGITAL MARKETS: AN EX Downloaded from https://academic.oup.com/jcle/advance-article/doi/10.1093/joclec/nhaa020/5874037 by guest on 18 December 2020 POST ASSESSMENT† Elena Argentesi,∗Paolo Buccirossi,†Emilio Calvano,‡ Tomaso Duso,§,∗ & Alessia Marrazzo,¶ & Salvatore Nava† ABSTRACT This paper presents a broad retrospective evaluation of mergers and merger decisions in markets dominated by multisided digital platforms. First, we doc- ument almost 300 acquisitions carried out by three major tech companies— Amazon, Facebook, and Google—between 2008 and 2018. We cluster target companies on their area of economic activity providing suggestive evidence on the strategies behind these mergers. Second, we discuss the features of digital markets that create new challenges for competition policy. By using relevant case studies as illustrative examples, we discuss theories of harm that have been used or, alternatively, could have been formulated by authorities in these cases. Finally, we retrospectively examine two important merger cases, Facebook/Instagram and Google/Waze, providing a systematic assessment of the theories of harm considered by the UK competition authorities as well as evidence on the evolution of the market after the transactions were approved. We discuss whether the competition authority performed complete and careful analyses to foresee the competitive consequences of the investigated mergers and whether a more effective merger control regime can be achieved within the current legal framework.

  • Diversification Strategy in Internet Industry: Google Inc. Example
    Afyon Kocatepe Üniversitesi Sosyal Bilimler Dergisi / Cilt: 20, Sayı: 3, Aralık 2018, 271-289 Afyon Kocatepe University Journal of Social Sciences / Volume: 20, No: 3, December 2018, 271-289 Yayın Geliş Tarihi (Submitted): Mart/March-2018 | Yayın Kabul Tarihi (Accepted): Aralık/December-2018 DOI: 10.32709/akusosbil.407405 Diversification Strategy in Internet Industry: Google Inc. Example İnternet Sektöründe Satın Alma Çeşitlendirme Stratejisi: Google Inc. Örneği Dr. Öğr. Üyesi Eyüp Bayram ŞEKERLİ 1, Doç. Dr. Eyüp AKÇETİN2 Abstract One of the growth strategies for firms is to buy other firms. Growth either may be related to main business area of firm or different fields from different sectors. This study examines the acquisition strategy of Google Inc. which is an important company in the oligopolistic internet industry with a limited number of operators (Amazon, Google, Microsoft, Facebook, etc.). Between the years of 2001-2017, 177 acquisitions were examined in this research,. As a result of this review, it appears that Google Inc. has acquired firms that manufacture in different technological areas. However, those acquisitions increased ability of generating revenues from its core business. Consequently, among 177 acquisitions, constrained-related diversification model is most frequently observed strategy which is aimed to increase performance of main business. Keywords: Acquisations, diversification strategy, internet sector, Google Inc. Özet İşletmelerin büyüme stratejilerinden birisi de diğer işletmeleri satın almaktır. Büyüme, işletmenin esas faaliyet alanı ile ilgili olabilirken, farklı sektörlerden farklı faaliyet alanlarını da içerebilmektedir. Bu çalışmada sınırlı sayıda işletmenin (Amazon, Google, Microsoft, Facebook gibi.) oluşturduğu oligopol bir yapıya sahip internet sektöründe önemli bir şirket olan Google Inc.’nin satın alma stratejisi incelenmiştir.
