To ensure the quality of a software system, developers perform an activity known as unit testing, where they write code (known as test cases) that verifies the individual software units that make up the system. Like production code, test cases are subject to bad programming practices, known as test smells, that hurt maintenance activities. An essential part of most maintenance activities is program comprehension which involves developers reading the code to understand its behavior to fix issues or update features. In this study, we conduct a controlled experiment with 96 undergraduate computer science students to investigate the impact of two common types of test smells, namely Assertion Roulette and Eager Test, on a student's ability to debug and troubleshoot test case failures. Our findings show that students take longer to correct errors in production code when smells are present in their associated test cases, especially Assertion Roulette. We envision our findings supporting academia in better equipping students withthe knowledge and resources in writing and maintaining high-quality test cases.

the growing demand for software developers and the increasing development complexity have emphasized the need for support in softwareengineering projects. this is especially relevant in light of advancements in artificial intelligence, such as conversational systems. A significant contributor to the complexity of software development is the multitude of tools and methods used, creating various contexts in which software developers must operate. Moreover, there has been limited investigation into the interaction between context-based chatbots and software developers through experimental user studies. Assisting software developers in their work becomes essential. In particular, understanding the context surrounding software development and integrating this context into chatbots can lead to novel insight into what software developers expect concerning these human-chatbot interactions and their levels of automation. In my research, I study the design of context-based adaptive interactions between software developers and chatbots to foster solutions and knowledge to support software developers at work.

Autonomic Networking is one of the main models proposed for the deployment of Networking Intents. Ideally, Intent should be specified by the user in a natural language (e.g., English), but it must then be transformed into a computer-executable representation that can then be mapped onto interactions with existing networking components. there currently is no consensus as to what language can be used to express the operational version of Networking Intents. the Autonomic System Specification Language (ASSL) was designed for the specification and verification of autonomic systems in general. We propose to use ASSL as the intermediate language to express the executable version of Networking Intents. Starting from a set of Intent examples (expressed in English), transformations of the examples into ASSL have been obtained. Using these examples, we show that ASSL is capable of expressing a very wide range of Networking Intents.

this article introduces an innovative study on residual stress analysis in Laser Powder Bed Fusion (LPBF) fabricated materials, focusing on an Al-3Ni-Ti-0.8Zr sample. By leveraging Swadener's theoretical approach alongside nanoindentation techniques, the research offers a cost-effective and easily applicable method for mapping residual stress patterns, distinguishing itself from more expensive and complex techniques like X-ray diffraction or destructive methods such as contour or drilling. the investigation correlates residual stress patterns with critical mechanical properties, including yield strength 265.03 MPa and ultimate tensile strength up to 347.5 MPa, thereby demonstrating the significant influence of LPBF process parameters on material characteristics. the findings provide initial validation of this accessible methodology, emphasizing its potential as a tool for understanding and mitigating residual stresses. As an ongoing endeavor, future work will expand upon these insights through broader data collection, rigorous validation, and comparative analyses with other stress detection techniques. this study marks a significant advancement in additive manufacturing research, aiming to optimize LPBF processes and improve material performance by offering a more straightforward yet effective alternative to traditional stress analysis methods.

Tissue engineering is a pivotal research domain, central to advancing biomedical manufacturing processes withthe aim of fabricating functional artificial organs and tissues. Addressing the pressing concern of organ shortages and myriad medical challenges necessitates innovative manufacturing techniques. Hydrogel scaffolds, due to their biocompatibility and extracellular matrix-mimicking porous structure, have emerged as prime candidates in this arena. Moreover, their hygroscopic properties and tunable mechanical characteristics render them suitable for various tissue engineering applications. Despite their promising attributes, a significant manufacturing challenge persists: the optimization of cellular growth within the confines of hydrogel scaffolds. Effective vascularization, essential for optimal cellular nutrient and oxygen supply, remains elusive. Our previous manufacturing research tackled this, introducing a novel hybrid Bio-Fabrication technique. this technique integrated coaxial electrospinning and extrusion-based bioprinting methodologies, yielding hydrogel scaffolds fortified with microtubes. these strategically embedded microtubes, modeled after capillary structures, function as microchannel diffusion conduits, enhancing cellular viability within the hydrogel matrix. A core aspect of scaffold manufacturing is ensuring the stability of its 3D architecture, especially post-swelling. Preliminary hypotheses suggest a gamut of factors including microtube shape, size, orientation, alignment, and density - play determinant roles in shaping the scaffold's mechanical attributes. this research rigorously examines the mechanical evolution of hydrogel scaffolds when supplemented with aligned electrospun microtubes across a spectrum of densities. A blend of sodium alginate (SA) and gelatin was selected for the hydrogel matrix due to their inherent biocompatibility and favorable mechanical properties. Different concentrations were prepared to assess the optimal mixt
