Software evolution has no common paradigm which practitioners can adhere to. On the contrary, there is a wide range of models, methods, techniques, and tools which are selected according to the specific task, the application domain, the professional experience, and the organizational culture. We argue that different approaches and technologies may be combined into a unique platform to satisfy the needs of software systems which evolve over long periods of time. This paper presents the Integrated Environment for Software Evolution Management (IESEM) which includes software repositories, reverse engineering tools, rationale capture tools, software measurement tools, and a user-friendly interface. It can manage heterogeneous systems characterized by various design methods and programming languages. IESEM is based on a central repository which stores software engineering artifacts, program code, design, and implementation decisions in the form of a traceability graph. The repository stores also software measures computed both from programs and external CASE repositories. Measures are used to control software degradation during its evolution and to support decisions based on quality factors. The key concepts of IESEM, its design, and implementation are presented. The use of IESEM during development and maintenance is discussed. A case study shows IESEM's effectiveness in performing maintenance tasks.

Knowledge about different aspects of software quality during software evolution can be valuable information for developers and project managers. It helps to reduce the number of defects and improves the internal structure of software. However, determining software?s quality and structure in heterogeneous systems is a difficult task. In this paper, a programming language independent framework for evaluating software metrics and analyzing software structure during software development and its evolution will be presented. The framework consists of the SMIILE tool for calculation of software metrics, extended with an analysis of software structure. The data are stored in a central repository via enriched Concrete Syntax Tree (eCST) for universal source code representation. The framework is demonstrated in a case study. The development of such a framework is a step forward to consistent support for software evolution by providing a change analysis and quality control. The significance of this consistency is growing today, when software projects are more complex, consisting of components developed in diverse programming languages.

SummaryUnanticipated changes to complex software systems can introduce anomalies such as duplicated code, suboptimal inheritance relationships and a proliferation of run-time downcasts. Refactoring to eliminate these anomalies may not be an option, at least in certain stages of software evolution. A class extension is a method that is defined in a module, but whose class is defined elsewhere. Class extensions offer a convenient way to incrementally modify existing classes when subclassing is inappropriate. Unfortunately existing approaches suffer from various limitations. Either class extensions have a global impact, with possibly negative effects for unexpected clients, or they have a purely local impact, with negative results for collaborating clients. Furthermore, conflicting class extensions are either disallowed, or resolved by linearization, with subsequent negative effects. To solve these problems we present classboxes, a module system for object-oriented languages that provides for behavior refinement (i. e. method addition and replacement). Moreover, the changes made by a classbox are only visible to that classbox (or classboxes that import it), a feature we call local rebinding. We present an experimental validation in which we apply the classbox model to both dynamically and statically typed programming languages. We used classboxes to refactor part of the Java Swing library, and we show two extensions built on top of classboxes which are (i) runtime adaptation with dynamically classboxes and (ii) expressing crosscutting changes.

The lack of a harmonized model exchange formats among modelling tools impedes communication between researchers, since the exchange and usage of existing models in various software environments can be very difficult. The RaDAR model inventory aims to provide a platform to exchange models among professionals utilizing the Food Safety Knowledge Exchange (FSKX) Format (de Alba Aparicio et al. 2018) as a harmonized model exchange format. FSKX defines a framework that encodes all relevant data, metadata, and model scripts in an exchangeable file format. However, the creation of such a file can be a time-consuming and difficult process. To increase the usage of the FSK standard, we developed the RaDAR model inventory web application that targets the process of creating an FSKX file for the end user. Our inventory aims to be a user-friendly tool that allows users to create, read, edit, write, execute and compile FSKX files within the web browser. The possibility of sharing models with the public or a specific group of people facilitates collaboration and the exchange of information. Since the RaDAR model inventory is based on the open-source technology of Project Jupyter (Granger and Perez 2021), it can support nearly all relevant programming languages executed within a reproducible cloud-computing environment. The intuitive nature of the RaDAR model along with its wide range of features reduce the threshold for contribution to a harmonized model exchange format and eases collaboration. The RaDAR model inventory can be accessed at http://ejp-radar.eu.

Existing and legacy software systems are the product of lengthy and individual developmental histories. Interoperability among such systems offers the support of global applications on these systems and intelligent information processing. However, interoperability among these heterogeneous systems is hampered by the absence of an integrated environment that would allow the development of global applications requiring intersystem cooperation. A uniform application-system interface is necessary to abstract the common properties of the global applications and of systems, mask their differences, and thus overcome this heterogeneity barrier. This paper presents such a solution, termed Remote System Interfaces (RSIs), which has been designed and implemented in the course of the InterBase project at Purdue University.

Traditional software development method will bring code tangling, code scattered and many other issues. Aspect-oriented programming came into being under this circumstance. AOP is a new programming paradigm which is independent of all the other programming languages. The scale and complexity of software systems increase continually. Efficiently control the complexity of software systems has already become a vitally important issue which needs to be addressed. In the modular design and implementation of software, cross cut always arise between primary functional modules and non-functional modules. This paper proposes a method to model and verify an UML activity diagram based aspect-oriented programming which enhance the capability of dealing with non-function requirements.

This chapter summarizes the main results described in this book and challenges and strategic directions in MDA reverse engineering. Reverse engineering is the process of analyzing software systems to extract software artifacts at a higher level of abstraction. Nowadays, software and system engineering industry evolves to manage new platform technologies, design techniques and processes. Architectural framework for information integration and tool interoperation, such as MDA, had created the need to develop new analysis tools and specific techniques. MDA is not itself a technology specification but it represents an evolving plan to achieve cohesive model-driven technology specifications. The original inspiration around the definition of MDA had to do with the middleware integration problem in internet. Beyond interoperability reasons, there are other good benefits to use MDA such as to improve the productivity, process quality and maintenance costs. The outstanding ideas behind MDA are separating the specification of the system functionality from its implementation on specific platforms, managing the software evolution from abstract models to implementations increasing the degree of automation and achieving interoperability with multiple platforms, programming languages and formal languages.

The ability to detect nanoscale objects is particular crucial for a wide range of applications, such as environmental protection, early-stage disease diagnosis and drug discovery. Photonic crystal nanobeam cavity (PCNC) sensors have attracted great attention due to high-quality factors and small-mode volumes (Q/V) and good on-chip integrability with optical waveguides/circuits. In this review, we focus on nanoscale optical sensing based on PCNC sensors, including ultrahigh figure of merit (FOM) sensing, single nanoparticle trapping, label-free molecule detection and an integrated sensor array for multiplexed sensing. We believe that the PCNC sensors featuring ultracompact footprint, high monolithic integration capability, fast response and ultrahigh sensitivity sensing ability, etc., will provide a promising platform for further developing lab-on-a-chip devices for biosensing and other functionalities.

This paper presents a resonant pressure microsensor with a wide range of pressure measurements. The developed microsensor is mainly composed of a silicon-on-insulator (SOI) wafer to form pressure-sensing elements, and a silicon-on-glass (SOG) cap to form vacuum encapsulation. To realize a wide range of pressure measurements, silicon islands were deployed on the device layer of the SOI wafer to enhance equivalent stiffness and structural stability of the pressure-sensitive diaphragm. Moreover, a cylindrical vacuum cavity was deployed on the SOG cap with the purpose to decrease the stresses generated during the silicon-to-glass contact during pressure measurements. The fabrication processes mainly contained photolithography, deep reactive ion etching (DRIE), chemical mechanical planarization (CMP) and anodic bonding. According to the characterization experiments, the quality factors of the resonators were higher than 15,000 with pressure sensitivities of 0.51 Hz/kPa (resonator I), −1.75 Hz/kPa (resonator II) and temperature coefficients of frequency of 1.92 Hz/°C (resonator I), 1.98 Hz/°C (resonator II). Following temperature compensation, the fitting error of the microsensor was within the range of 0.006% FS and the measurement accuracy was as high as 0.017% FS in the pressure range of 200 ~ 7000 kPa and the temperature range of −40 °C to 80 °C.
