STORE: EMBEDDED PERSISTENT STORAGE FOR CLOJURE PROGRAMMING LANGUAGE Konrad Grzanek1 1IT Institute, Academy of Management, Lodz, Poland [email protected] Abstract Functional programming is the most popular declarative style of programming. Its lack of state leads to an increase of programmers' productivity and software robustness. Clojure is a very effective Lisp dialect, but it misses a solid embedded database implementation. A store is a proposed embedded database engine for Clojure that helps to deal with the problem of the inevitable state by mostly functional, minimalistic interface, abandoning SQL and tight integration with Clojure as a sole query and data-processing language. Key words: Functional programming, Lisp, Clojure, embedded database 1 Introduction Functional programming languages and functional programming style in general have been gaining a growing attention in the recent years. Lisp created by John McCarthy and specified in [8] is the oldest functional pro- gramming language. Some of its flavors (dialects, as some say [9]) are still in use today. Common Lisp was the first ANSI standardized Lisp dialect [13] and Common Lisp Object System (CLOS) was probably the first ANSI stan- dardized object oriented programming language [14]. Apart from its outstand- ing features as a Common Lisp subset. Various Lisps were used in artificial intelligence [11] and to some extent the language comes from AI labs and its ecosystem. Common Lisp was used as the language of choice by some AI tutors, like Peter Norvig (in [10]). But the whole family of languages address general problems in computer science, not only these in AI. John Backus argues [3] that the functional style is a real liberation from the traditional imperative languages and their problems. -
What We Know About Testing Embedded Software
What we know about testing embedded software Vahid Garousi, Hacettepe University and University of Luxembourg Michael Felderer, University of Innsbruck Çağrı Murat Karapıçak, KUASOFT A.Ş. Uğur Yılmaz, ASELSAN A.Ş. Abstract. Embedded systems have overwhelming penetration around the world. Innovations are increasingly triggered by software embedded in automotive, transportation, medical-equipment, communication, energy, and many other types of systems. To test embedded software in a cost effective manner, a large number of test techniques, approaches, tools and frameworks have been proposed by both practitioners and researchers in the last several decades. However, reviewing and getting an overview of the entire state-of-the- art and the –practice in this area is challenging for a practitioner or a (new) researcher. Also unfortunately, we often see that some companies reinvent the wheel (by designing a test approach new to them, but existing in the domain) due to not having an adequate overview of what already exists in this area. To address the above need, we conducted a systematic literature review (SLR) in the form of a systematic mapping (classification) in this area. After compiling an initial pool of 560 papers, a systematic voting was conducted among the authors, and our final pool included 272 technical papers. The review covers the types of testing topics studied, types of testing activity, types of test artifacts generated (e.g., test inputs or test code), and the types of industries in which studies have focused on, e.g., automotive and home appliances. Our article aims to benefit the readers (both practitioners and researchers) by serving as an “index” to the vast body of knowledge in this important and fast-growing area. -

A Variability-Aware Module System
A Variability-Aware Module System Christian Kästner, Klaus Ostermann, and Sebastian Erdweg Philipps University Marburg, Germany Module systems enable a divide and conquer strategy to software develop- ment. To implement compile-time variability in software product lines, mod- ules can be composed in different combinations. However, this way variability dictates a dominant decomposition. Instead, we introduce a variability-aware module system that supports compile-time variability inside a module and its interface. This way, each module can be considered a product line that can be type checked in isolation. Variability can crosscut multiple modules. The module system breaks with the antimodular tradition of a global variabil- ity model in product-line development and provides a path toward software ecosystems and product lines of product lines developed in an open fashion. We discuss the design and implementation of such a module system on a core calculus and provide an implementation for C, which we use to type check the open source product line Busybox with 811 compile-time options. 1 Introduction A module system allows developers to decompose a large system into manageable sub- systems, which can be developed and checked in isolation [13]. A module hides informa- tion about internal implementations and exports only a well-defined and often machine- enforced interface. This enables an open-world development style, in which software can be composed from modular self-contained parts. The need for compile-time variability, for example in software product lines [6, 17, 10], challenges existing module systems. To tailor a software system, stakeholders may want to select from compile-time configuration options (or features) and derive a specific configuration (or variant, or product) of the system. -

Portability Techniques for Embedded Systems Data Management
Portability Techniques for Embedded Systems Data Management McObject LLC st 33309 1 Way South Suite A-208 Federal Way, WA 98003 Phone: 425-888-8505 E-mail: [email protected] www.mcobject.com Copyright 2020, McObject LLC Whether an embedded systems database is developed for a specific application or as a commercial product, portability matters. Most embedded data management code is still “homegrown,” and when external forces drive an operating system or hardware change, data management code portability saves significant development time. This is especially important since increasingly, hardware’s lifespan is shorter than firmware’s. For database vendors, compatibility with the dozens of hardware designs, operating systems and compilers used in embedded systems provides a major marketing advantage. For real-time embedded systems, database code portability means more than the ability to compile and execute on different platforms: portability strategies also tie into performance. Software developed for a specific OS, hardware platform and compiler often performs poorly when moved to a new environment, and optimizations to remedy this are very time-consuming. Truly portable embedded systems data management code carries its optimization with it, requiring the absolute minimum adaptation to deliver the best performance in new environments. Using Standard C Writing portable code traditionally begins with a commitment to use only ANSI C. But this is easier said than done. Even code written with the purest ANSI C intentions frequently makes assumptions about the target hardware and operating environment. In addition, programmers often tend to use available compiler extensions. Many of the extensions – prototypes, stronger type- checking, etc, – enhance portability, but others may add to platform dependencies. -

Karmorea, Anjali R. Mahajanb Research Scholar, Department of Computer Science and enginnering, G. H. Raisoni College of Engineering, Nagpur, India. Head, Department of Information Technology, Government Polytechnic, Nagpur, India. Abstract Assuring the quality of embedded system is posing a big challenge for software testers around the globe. Testing of one embedded system widely differs from another. The approach presented in the paper is used for the testing of safety critical feature of embedded system. The input and outputs are trained validated and tested via ANN. Security is provided via skipping invalid and critical classes and by embedding secret key in the Ram of embedded device. The work contributes simulating environment where cost and time required for testing of embedded systems will be minimized, which removes drawback of traditional approaches. Keywords: Embedded system testing; Black box testing; Safety critical embedded systems; Artificial neural network. 1. Introduction Testing is the most common process used to determine the quality and providing security for embedded systems. In the embedded world, testing is an immense challenge. In the test plan, the distinguished characteristics of embedded systems must be reflected as these are application specific. They give embedded system exclusive and distinct flavor. Real-time systems have to meet the challenge of assuring the correct implementation of an application not only dependent upon its logical accuracy, but also its ability to meet the constraints of timing. -

BIM AND SENSOR BASED DATA MANAGEMENT SYSTEM FOR CONSTRUCTION SAFETY MONITORING ABSTRACT Purpose: This research investigates the integration of real-time monitoring of thermal conditions within confined work environments through wireless sensor network (WSN) technology when integrated with Building Information Modelling (BIM). A prototype system entitled Confined Space Monitoring System or CoSMoS (which provides an opportunity to incorporate sensor data for improved visualization through new add-ins to BIM software) was then developed. Design/ methodology/ approach: An empirical study was undertaken to compare and contrast between the performance (over a time series) of various database models to find a back-end database storage configuration that best suits the needs of CoSMoS. Findings: Fusing BIM data with information streams derived from wireless sensors challenges traditional approaches to data management. These challenges encountered in the prototype system are reported upon and include issues such as hardware/ software selection and optimisation. Consequently, various database models are explored and tested to find a database storage that best suits the specific needs of this BIM-wireless sensor technology integration. Originality/ value: This work represents the first tranche of research that seeks to deliver a fully integrated and advanced digital built environment solution for automating the management of health and safety issues on construction sites. 1 KEYWORDS Building information modelling, digital built environment, health and safety management, sensor data, data management INTRODUCTION According to U.S. Bureau of Labor Statistics (BLS), a total of 796 fatal injuries were recorded in the U.S. construction industry in 2013 from which 14% of fatalities were due to the exposure to hazardous environment and 2% were caused by fire and explosions (BLS, 2013).
