In modern software engineering the task of migration from one system environment to another may arise very often (e.g. software migrating from Windows to Linux or from desktop PC to some mobile platform). This task may be accomplished manually, but this will certainly be not cost- and time-effective and will require additional testing and verification. Therefore various automated techniques aimed to solve this problem seem to be very useful. The article takes into consideration one of such approaches, mainly focused on transferring source code between two library environments. © 2011 IEEE.

Games appeal to all kinds of people and are used for a wide range of purposes, from pure entertainment to educational research. Software engineering is an area of computing that has much content to explore, distributed in different knowledge areas. Thus, there are many theoretical classes that make learning tiresome. In this scenario, educators and researchers are looking for new methods to engage students in order to facilitate the learning process. Many studies have already been produced using games as a teaching method. However, a recurring mistake when using games as a teaching method is the application of the wrong approach to a context that often hinders student learning. This paper presents a systematic mapping that aims to identify the main ways that games are being used as a teaching method focused on Software engineering. The results highlight five ways of using games as a teaching method, where Game-based Learning, Digital Game-based Learning and Gamification are the most used ones. © CIbSE 2020.

Secure provenance techniques are essential in generating trustworthy provenance records, where one is interested in protecting their integrity, confidentiality, and availability. In this work, we suggest an architecture to provide protection of authorship and temporal information in grid-enabled provenance systems. It can be used in the resolu-tion of conflicting intellectual property claims, and in the reliable chronological reconstitution of scientific experiments. We observe that some techniques from public key infrastructures can be readily applied for this purpose. We discuss the issues involved in the implementation of such architecture and describe some experiments realized with the proposed techniques. © 2008 IEEE.

A revision of Union College's Introduction to engineering and computer Science course is presented. The change include the introduction of a design project and competition, the presentation of engineering and computer science concepts under a unifying theme, and the introduction of weekly talks from outside speakers. The course instruction also changed from a series of modules taught by different faculty to a structure in which all the faculty taught all the topics in the course. If this approach is used with a group of cooperative faculty, the benefits of the exposure to different teaching styles and understanding of other disciplines can be positive.

Speculative Multithreading (SpMT) increases the performance by means of executing multiple threads speculatively to exploit thread-level parallelism. By combining software and hardware approaches, we have improved the capabilities of previous WaveScalar ISA on the basis of Transactional Memory system for the WaveCache Architecture. Threads are extracted at the course of static compiling, and speculatively executed as a thread-level transaction that is supported by extra hardware components, such as Thread-Context-Table (TCT) and Thread-Memory-History (TMH). We have evaluated the SpMT WaveCache with 6 real benchmarks from SPEC, Mediabench and Mibench. On the whole, the SpMT WaveCache outperforms superscalar architecture ranging from 2X to 3X, and great performance gains are achieved over original WaveCache and Transactional WaveCache as well. © 2008 IEEE.

Software Product Lines (SPLs) have been used to develop mobile and context-aware applications, which provide services and data for their users from anywhere and at any time using context information. In SPLs, commonality and variability of a system family are identified and often documented in a feature model. However, the development of a feature model for mobile and context-aware SPLs is not trivial, since it should comprise system and context information. Furthermore, the consistency check of feature models in the considered domain is also complex and demands advanced skills of software engineers. This paper proposes a mechanism to formalize and verify the correctness and consistency of feature models for mobile and context-aware SPLs based on a profile enriched with OCL specifications. © 2011 IEEE.

Precision farming is an optimized management farming scheme that seeks to link the real-time needs of crops with the nutrients to be administered. Sensing platforms that can monitor the physiological status of crops in situ are key to enabling timely and localized interventions. However, the underdevelopment of plant sensing strategies limits the potential of precision farming. In this Review, we discuss the challenges and advancements in phyto-monitoring, focusing on strategies that are applicable to a wide range of plant species and suitable for field deployment. We explore species-agnostic sensors, including optical and electrochemical sensors, whose operation is based on principles that are widely applicable to all plant species. These platforms enable real-time monitoring of the physiological state of crops by assessing key biomarkers, such as plant hormones, and metabolites such as salicylic acid and reactive oxygen species. Evaluating these systems, we conclude that an integrative sensing approach is necessary to compensate for the limitations of the individual methods and can provide a holistic view of crop health. Cost-effective species-agnostic sensors are thus needed to provide information that can be used to minimize the resource footprint of farming and meet the growing global demand.

An evolutionary game-theoretic approach for analysis of startups’ funding mechanisms considering their opportunistic and responsible behavior based on system dynamics

Purpose: Collaborating with startups is a fast track to green technological innovation (GTI) implementation for tech firms. On the other hand, startups’ opportunistic behavior during the collaboration could lead to GTI failure and a waste of tech firms’ investment. Accordingly, it is essential to conduct a dynamic analysis of the evolutionary behavior of tech firms and startups over time. In this regard, under government intervention, we consider a collaborative structure between two populations, including tech firms and startups. Design/methodology/approach: In this study, an evolutionary game structure based on system dynamics was developed to explain the tech firms’ and startups’ evolutionary trends, emphasizing investment mechanisms and the startup’s commitment level through a feedback process. For this purpose, the influence of the startups’green innovative efforts on the system’s evolution under two feedback loops was investigated. Furthermore, the effects of tech firms’ penalty strategies and government intervention on system evolutionary behavior was analyzed. Findings: The simulations revealed that applying the dynamic punishment policy can control the game’s oscillations in the evolutionary model and increase the startup’s and tech firm’s stability rate. When the penalty values change, and the startups’ credibility level is a variable under the impact of the green technological innovation features, it affects the evolutionary behavior of players over time through the positive feedback loop. It was also found that, despite the startups' opportunistic behaviors, effective government interference could raise the tech firms' tendency to invest in startups. Originality/value: Unlike previous studies, we focus on a dynamic analysis approach to investigate the collaborative structure between tech firms and startups. For the first time, we investigate the evolutionary behavior of startups and tech firms in positive and negative feedback structures to see how GTI f

The operation of a radar system requires a trade-off between detection capabilities, power efficiency, and adjacent channel power minimization. Specifically, wide signal bandwidth is important for range detection. This paper presents how load-pull data taken for multiple linear frequency-modulated chirp waveforms with different bandwidths can be used to select the chirp waveform with the largest bandwidth possible, while meeting adjacent-channel power ratio and power-added efficiency requirements. This approach utilizes plots of adjacent-channel power ratio and power-added efficiency surfaces within a Smith tube, a three-dimensional, cylindrical extrapolation of the traditional Smith chart. A measurement example is given to illustrate the design approach. This approach will be useful in the design of range radars, and also is likely to find use in enabling real-time reconfiguration of future radars for varying spectral environments and efficiency requirements. © 2014 IEEE.

Future Internet of Things (IoT) devices will need to maintain high power efficiency while being able to reconfigure for changing performance requirements and operating frequencies. The design of quickly reconfigurable power amplifiers able to maintain high efficiency and meet spectral requirements will be critical to success. This paper discusses fast optimization techniques that will be useful in real-time optimization of transmitter power amplifiers: (1) a vector-based algorithm to find the load impedance giving the highest power-added efficiency (PAE) while keeping the adjacent-channel power ratio (ACPR) below a prespecified minimum, (2) the use of a spectral mask directly in the load-pull optimization in place of the ACPR, and (3) the extension of the Smith Chart to a three-dimensional, cylindrical "Smith Tube" for optimization involving an additional parameter: the waveform bandwidth. This paper builds a framework for design and the real-time optimization of reconfigurable, efficient, and spectrally compliant IoT power amplifiers. © 2014 IEEE.
