The system aims to automate the process of testing the devices on the final production line. The system uses a stimulation board which electrically stimulates touch screens, completely removing mechanical parts which induce lag and instability. Framework communicates with the stimulation board, sending signals which correspond to types of stimulation the board is supposed to achieve. Supported moves are: single touch, single release, multi touch, multi release, full release, line (swipe), multiline (pinch). The framework communicates with the stimulation board via the serial UART or Local Area Network interface. The testing is performed in following steps: (1) framework sends signals to the stimulation board, (2) board stimulates the device, (3) grabber captures the image of the screen on the device and (4) PC receives the image and verifies its correctness. The preliminary results show that the system is capable of reliable stimulation of touch screens which allows the creation of the complete system for automated testing.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133309284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper discusses such aspects of intermediate level obfuscation as input data analysis, mixing of contexts, external function calls, etc. The focus is set on working out an optimization resistant intermediate level obfuscation algorithm that can reliably protect routines from unauthorized analysis and modification.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123446670","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many large distributed systems employ Ethernet or even full TCP/IP stack for communication. Two prevalent protocols are used for clock synchronization in these networks, in particular, Network Time Protocol (NTP) and Precise Time Protocol (PTP). In this short paper, we present a method for practical performance evaluation of clock synchronization within a distributed environment consisting of nodes running a commodity real-time operating system. The results of measurement provide us a hint on the degree of synchronization that can be practically achieved among the set of distributed devices. The main contribution of this paper is to provide a simple method for practical evaluation of synchronization methods for a distributed control system and presenting some preliminary data from the measurement. A complete result set may be used, e.g., for defining a performance estimation functions in a platform-based design approach to networked control systems.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126238832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, this modeling is often implemented in the Simulink environment, which offers strong support for modeling complex systems. Moreover, via modeling, various analyses can be applied to the systems at design time. An important analysis is of the data types assigned to signal variables. Such analysis enables identification of potential problems during model compilation and so prevent runtime surprises. To assist the system designer, Simulink supports which includes a step for automatic data type inferencing (e.g., based on designed signal value ranges and on the connection structure of design elements). In contrast to the Simulink implementation of the inferencing in a code base, which favors efficiency, the work presented here raises the level of abstraction by explicitly modeling the inferencing logic. This unlocks benefits such as the ability to (i) reason about the logic, (ii) implement different logic by advanced users, and (iii) experiment with different ordering of other logic in the model compilation.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115698111","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The process of transforming an in-memory object instance into bytes of an XML document is called XML serialization, the opposite direction is XML deserialization. Both processes introduce some cost that influences the overhead of the communication. This paper proposes a performance model that can estimate the cost of XML serialization and deserialization on Java platform based on a priori knowledge of the type and size of the XML messages. Type and size information of the XML messages is usually available in the form of an interface definition, such as a Web Services Description Language (WSDL) file. We show that in most cases the cost can be expressed as a linear function of the object size, but exceptions are discussed as well. The suggested model is validated with measurements.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127216966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One of the main problems in the current world of information technologies is the ever-increasing amount of digital data and complexity of problems that are being solved. In such conditions, developing a distributed system that needs to response promptly, can be very difficult and without proper techniques can lead to failure. Processing of potentially large volumes of incoming messages or events from various sources is also specific to the reactive computing. It can be assumed that the number of resources and their diversity will only grow. For that reason we have analyzed common approaches in distributed systems development. In this paper we introduce complex event processing. We try to evaluate its assets concerning design, implementation, modifiability, and flexibility of reactive distributed systems. For this purpose, we have implemented a functional model of an electronic toll collection system, based on system specifications for Slovak conditions. Significant flexibility is achieved in comparison with existing solutions. We also present the possibilities of complex event processing application in reactive distributed system design. Based on gained knowledge even implemented a functional model we have evaluated complex event processing impact on system's functionality, modifiability, performance and other characteristics.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125244941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper pedestrian navigation is being discussed using commercial mobile phones in that particular case, when global navigation systems are not available. Furthermore no beacon or internet-based aid is applied. This type of indoor navigation is called offline indoor navigation, where the main concept is to use onboard sensors of mobile phones and apply different filtering solutions and algorithms for examples such algorithms that follows pedestrian movements. In this paper we compare different solutions for indoor navigation with real measurements. Therefore this work can be considered as a summary work for indoor navigation techniques.

The goal of this methodology is generation of test cases for the new functional testing campaign based on the test coverage information from the previous testing campaign, in order to maximize the test coverage. Test coverage information is used for selection of proper test cases in order to improve the quality of testing and save available resources for testing. As an output, a set of test cases is produced. Generated test cases are processed by the test Executor application that decides whether results have passed or failed, based on the results of image grabbing, OCR text extraction, and comparison with expected text. The presented methodology is finally validated by means of a case-study targeting an Android device. The results of the case study are affirmative and they indicate that the proposed methodology is applicable for testing embedded systems of this kind.","PeriodicalId":314029,"journal":{"name":"2013 3rd Eastern European Regional Conference on the Engineering of Computer Based Systems","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114547648","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
