Developing and Benchmarking Native Linux Applications on Android
Developing and Benchmarking Native Linux Applications on Android Leonid Batyuk, Aubrey-Derrick Schmidt, Hans-Gunther Schmidt, Ahmet Camtepe, and Sahin Albayrak Technische Universit¨at Berlin, 10587 Berlin, Germany {aubrey.schmidt,leonid.batyuk,hans-gunther.schmidt,ahmet.camtepe, sahin.albayrak}@dai-labor.de http://www.dai-labor.de Abstract. Smartphones get increasingly popular where more and more smartphone platforms emerge. Special attention was gained by the open source platform Android which was presented by the Open Handset Al- liance (OHA) hosting members like Google, Motorola, and HTC. An- droid uses a Linux kernel and a stripped-down userland with a custom Java VM set on top. The resulting system joins the advantages of both environments, while third-parties are intended to develop only Java ap- plications at the moment. In this work, we present the benefit of using native applications in Android. Android includes a fully functional Linux, and using it for heavy computational tasks when developing applications can bring in substantional performance increase. We present how to develop native applications and software components, as well as how to let Linux appli- cations and components communicate with Java programs. Additionally, we present performance measurements of native and Java applications executing identical tasks. The results show that native C applications can be up to 30 times as fast as an identical algorithm running in Dalvik VM. Java applications can become a speed-up of up to 10 times if utilizing JNI. Keywords: software, performance, smartphones, android, C, Java. 1 Introduction With the growing customer interest in smartphones the number of available platforms increases steadily. -

Gómez (*) Chief Editor International Institute of Social Studies of Erasmus University Rotterdam (*) [email protected] The International Journal of Community Currency Research was founded 23 years ago, when researchers on this topic found a hard time in getting published in other peer reviewed journals. In these two decades the academic publishing industry has exploded and most papers can be published internationally with a minimal peer-review scrutiny, for a fee. Moreover, complementary currency research is not perceived as extravagant as it used to be, so it has now become possible to get published in journals with excellent reputation. In that context, the IJCCR is still the first point of contact of practitioners and new researchers on this topic. It offers open access, free publication, and it is run on a voluntary basis by established scholars in the field. In any of the last five years, it has received about 25000 views. -

Cardinalities of Finite Relations in Coq with Applications ∗ Paul Brunet Univ. Lyon, CNRS, ENS de Lyon, UCB Lyon 1, LIP, UMR 5668 Damien Pous Univ. Lyon, CNRS, ENS de Lyon, UCB Lyon 1, LIP, UMR 5668 Insa Stucke Institut f¨urInformatik, Christian-Albrechts-Universit¨atzu Kiel, Germany Abstract In this paper we present an extension of a Coq library for relation algebras and related algebraic structures. So far, the library did not provide any tools about the cardinalities of relations. Thus we add an algebraic axiomatisation of cardinalities. Its point-free nature makes it possible to reason about cardinal purely algebraically, which is well-suited for mechanisation. We present several applications, in the area of graph theory and program verification. -
A Proposal for a Multilevel Relational Reference Language
A Proposal for a Multilevel Relational Reference Language Gunther Schmidt Institute for Software Technology, Department of Computing Science Federal Armed Forces University Munich, 85577 Neubiberg e-Mail: [email protected] Abstract A highly expressive multilevel relational reference language is proposed that covers most possibilities to use relations in practical applications. The language is designed to describe work in a heterogeneous setting. It originated from a Haskell-based system announced in [Sch02], fore- runners of which were [HBS94,Hat97]. This language is intended to serve a variety of purposes. First, it shall allow to formulate all of the problems that have so far been tackled us- ing relational methods providing full syntax- and type-control. Trans- formation of relational terms and formulae in the broadest sense shall be possible as well as interpretation in many forms. In the most simple way, boolean matrices will serve as an interpretation, but also non- representable models as with the Rath-system may be used. Proofs of relational formulae in the style of Ralf or in Rasiowa-Sikorski style are aimed at. Cooperation and communication around this research was partly spon- sored by the European Cost Action 274: Tarski (Theory and Appli- cations of Relational Structures as Knowledge Instruments), which is gratefully acknowledged. 1Introduction When an engineer is about to design an artefact and has to apply Linear Algebra methods (such as solving systems of linear equations or determining eigenvalues and eigenvectors), he will approach the respective computing center and most certainly get the necessary software. When the matrices considered become boolean matrices, i.e., relations, the situation changes dramatically. -

From the very beginning we started working on the book having in mind to collect exactly 100 short CVs. This was an artificial decision with respect to the number of Romanian computer scientists, but natural having in view the circumstances the volume was born: it belongs to a series initiated by the Romanian Academy on the occasion of celebrating one century since the Great Romania was formed, at the end of the First World War. -
