Background: Code review is a cognitively demanding and time-consuming process. Previous qualitative studies hinted at how decomposing change sets into multiple yet internally coherent ones would improve the reviewing process. So far, literature provided no quantitative analysis of this hypothesis.
Aims: (1) Quantitatively measure the effects...

With the growth of global population, the big cities become increasingly crowded. It is not rare to see large crowds in public transportations and events with masses of visitors, such as music festivals and football matches. The question “How to deal with crowds” is receiving attention, both from academia and practical crowd management.

In order to analyse the flow characteristics of free-surface vortexes and to validate the Burgers vortex model by using stereo particle image velocimetry, experiments are conducted in a 600 mm diameter vortex tank. Measured axial velocities indicate that 10–25% of the flow is transported through the vortex core. The velocity profiles show that...

The variety of fruits and vegetables in today’s supermarkets is enormous. We investigated how color may lead consumers to anticipate differences in product properties. Forty volunteers rated the expected properties for carrots with different colors presented in pictures, together with their familiarity, purchase intention, and intended...

Purpose: The purpose of this paper is to describe the quasi-experiment setting to test the formulated design support (developed in the author’s PhD research) within a design research methodology (DRM) framework. This support intends to help designers to consciously engage rural families within a development aid scenario and increase their...

Driver mental workload is an important factor in the operational safety of automated driving. In this study, workload was evaluated subjectively (NASA R-TLX) and objectively (auditory detection-response task) on Dutch public highways (∼150 km) comparing manual and supervised automated driving in a Tesla Model S with moderators automation...

Adding steel fibers to concrete improves the capacity in tension-driven failure modes. An example is the shear capacity in steel fiber reinforced concrete (SFRC) beams with longitudinal reinforcement and without shear reinforcement. Since no mechanical models exist that can fully describe the behavior of SFRC beams without shear reinforcement...

We challenge the unquestioning pursuit of the appearance of objectivity and ingrained designer-user dualism in human-centred design research and propose a
resurrection of introspection as a valid approach to investigating subjective experiences. Through comparing epistemic perspectives and reviewing the
histories of introspection in...

Apart from the soil erodibility parameter, the critical shear stress is the most important parameter in predicting erosion rates. On the basis of experiments several empirical formulas have already been de-veloped which relate the critical shear stress to soil properties. Based on these findings and supported by new large scale experiments, a...

Adaptive Cruise Control (ACC) and automated vehicles can contribute to reduce traffic congestion and accidents. Field operational Tests have shown that drivers may prefer to deactivate ACC systems that are inactive at low speeds in dense traffic conditions and before changing lanes. These transitions between automated and manual driving are...

This article focuses on the influence of state-led urban redevelopment on the place attachment of deprived and old homeowners living in danwei communities that are facing demolition in Shenyang, China. It investigates lived experiences through in-depth interviews with homeowners in the context of the pre-demolition phase, i.e. an inevitable...

The technique called "flameless combustion", also denoted as "MILD" combustion, was developed to reduce the nitrogen oxides (NOx) emission in the combustion process. The term "flameless" refers to the low visibility of the flame. The technique is particularly of interest when hot exhaust gas is used to preheat inlet air to high temperature. The...

Multimedia systems are typically optimized in a way that maximizes users’ satisfaction of using the systems/services. This user satisfaction is what is commonly referred to as Quality of Experience (QoE). For visual media, such as images and videos, the optimization of QoE has meant reducing the visibility of artifacts (e.g. noise or other...

Despite the massive forced relocation of residents during urban restructuring in China, there is no systematic overview regarding how residents experience the process and its outcomes. Most studies concerning urban restructuring in China directly equate forced relocation with displacement, which has a negative connotation. This predominantly...

The cultural attributes of architecture in touristic cities are vital to city image building, city branding, and rebranding, as well as generating more economic profits for sustainable urban development, and protecting cultural sustainability. However, many studies on this theme focus on the singularity of architecture referring to its...

Space debris poses a big threat to operational satellites which form a crucial infrastructure for society. According to the main source of information on space debris, the U.S. Space SurveillanceNetwork (SSN), more than 17 500 objects larger than 10 cmhave been catalogued as of February 2017. Among the total number of objects in orbit, only 1875...

In this paper, careful consideration is paid for structural glass elements under fire loading. In particular, a thermo-mechanical Finite Element (FE) numerical investigation is carried out in ABAQUS on small-scale structural glass elements exposed to fire. Taking advantage of past literature efforts, major thermal effects on the material...

There is growing interest in the adoption of open educational resources (OER) and open educational practices (OEP) in a variety of contexts. Continuing professional development (CPD) among practitioners in the effective adoption of OER and OEP is critical in this scenario. Massive open online courses (MOOCs), which also grew as part of the open...
