The purpose of this paper is to investigate the effects of electric current stressing on damping properties of Sn5Sb solder.

Abstract

Purpose

The purpose of this paper is to investigate the effects of electric current stressing on damping properties of Sn5Sb solder.

Design/methodology/approach

Uniformly shaped Sn5Sb solders were prepared as samples. The length, width and thickness of the samples were 60.0, 5.0 and 0.5 mm, respectively. The damping properties of the samples were tested by dynamic mechanical analyzer with a cooling system to control the test temperature in the range of −100 to 100°C. Simultaneously, electric current was imposed to the tested samples using a direct current supply. After tests, the samples were characterized using scanning electron microscope, electron backscatter diffraction and transmission electron microscope, which was aimed to figure out the damping mechanism in terms of electric current stressing induced microstructure evolution.

Findings

It is confirmed experimentally that the increase in damping properties is due to Joule heating and athermal effects of current stressing, in which Joule heating should make a higher contribution. G–L theory can be used to explain the damping properties of strain amplitude under current stressing by quantitative description of geometrically necessary dislocation density. While the critical strain amplitude and high temperature activation energy decrease with increasing electric current.

Originality/value

These results provide a new method for vibration reliability evaluation of high-temperature lead-free solders in serving electronics. Notably, this method should be also inspiring for the mechanical performance evaluation and reliability assessment of conductive materials and structures serving under electric current stressing.

The purpose of this paper is to investigate the nonsimultaneous impact of three impactors with spherical tip on the response of a low-velocity impact on a beam.

Abstract

Purpose

The purpose of this paper is to investigate the nonsimultaneous impact of three impactors with spherical tip on the response of a low-velocity impact on a beam.

Design/methodology/approach

In this research, the third-order shear deformation theory of the beam with hyperbolic shear-strain function is used. Hamilton’s principle is applied to derive the motion equations. To simulate nonsimultaneous impacts, by using the Hertz nonlinear contact law, the contact of the impactors with different times is simulated. Comparisons with other articles are carried out in the one impactor form.

Findings

In the parametric study, the histories of the contact force and displacement of the beam are investigated in the presence of only one impactor in the center of the beam and also in the presence of three impactors, one in the center of the beam and the other two around the first impactor with a delay. One of the important and noteworthy points is that the presence of two impactors with a delay causes the maximum contact force and contact time to decrease and the maximum displacement of the beam center to increase.

Originality/value

The original point of this paper is what is the difference between the impact response of one projectile and three nonsimultaneous projectiles on the beam.

Abstract

Purpose

Older adults often experience loneliness as a vicious circle, in which loneliness builds more loneliness. Breaking this cycle is key to minimize the experience of loneliness. MOAI LABS is a European project that adopts a codesign process to develop digital solutions to address loneliness in older adults. This study aims to adopt a solution-based approach to capture solutions that community-dwelling older Portuguese adults who feel loneliness already experience in their lives.

Design/methodology/approach

Six individuals (aged 64–86 years) answered two solution-based questions: miracle and exceptions. Findings were obtained from one group discussion session that was audio-recorded, transcribed and submitted to qualitative analysis.

Findings

Main findings suggest that participants feel comfort in imagining their desired scenarios that involve being with their loved ones, better health conditions, adequate housing settings and contact with nature.

Originality/value

The findings highlight that leaving loneliness alone seems to be a path that may be facilitated by digital solutions that display solution-based questions, such as online platforms for social connection, virtual care and monitoring, design of smart home devices and the creation of immersive virtual reality experiences to explore nature, complemented by psychosocial support.

Abstract

Purpose

This study aims to assess terrorism activities to identify measures required to mitigate the rise of terrorism activities and their metamorphosis into organised criminal activity through the prevention, disruption and dismantling of sources of financing terrorism.

Design/methodology/approach

A qualitative methodology was adopted for this study using descriptive synthesis from recent publications and reports of reputable organisations, i.e. relevant grey literature, key informant interview and a focus group discussion. This triangulation approach was used to cross-validate the findings.

Findings

The findings revealed that terrorism financing is most likely linked to organised crime for generating revenues and is further used to finance the activities of terrorists.

Practical implications

Terrorists operate from places with little or no presence of governance and, better still, ungovernable spaces for carrying out legitimate businesses, raising internally generated revenues from protection fees, ransoms and taxes. This space further allows domestic collaboration with local criminal gangs to exploit natural mineral resources. If the market for these resources is across borders, international or transnational criminal groups collaborate with terrorists to move the goods and assist with financial services for the generated proceeds.

Originality/value

This study assessed the emerging links between terrorism financing and organised crime in Nigeria.

Abstract

Purpose

The purpose of this study is to reveal the relationship between digital nomadism and regional development.

Design/methodology/approach

In the research, an interpretive approach was used to obtain an in-depth understanding of the relationship between digital nomadism and regional development and to examine a specific issue in more detail.

Findings

Digital nomads are constantly traveling. In this way, they provide income transfer to the places they visit. They positively affect the promotion of the region and contribute to the increase of the human capital of the regions.

Research limitations/implications

Viewed from the development agency perspective as a representative of a regional development agency.

Practical implications

Tips are presented on how the digital nomad theme can be managed in regional development.

Social implications

Regional development does not only include economic development, but also prioritizes the subjective well-being of local residents. For this reason, it has been emphasized that digital nomad arrangements in the name of regional development should not only be perceived as attracting new generation tourists to the region, but will also be a tool for the sociocultural development of local residents.

Originality/value

This study outlines the issue of how digital nomadism has become an alternative tool in the regional development.

Abstract

Purpose

This study aims to inform and guide information professionals in thinking clearly about the challenges and opportunities this technology may create.

Design/methodology/approach

This column uses the Web browser Arc as a focal point for exploring elements that seem key to understanding how artificial intelligence (AI) may change our relationship with information. Large language model’s were used to help draft or rewrite sentences. That text was then reviewed or revised by the author.

Findings

The following elements are key to understanding the potential of informational interface software like Arc. The ability to abstract information from the original content. The ability to produce multimedia compelling user experiences. The ability to “read” multimodal forms of information and take action based on that “understanding”. This may impact the value exchange between the user and the underlying information, with implications for libraries.

Research limitations/implications

Everything about AI the future of AI or any technology is speculative.

Practical implications

Libraries that wish to continue to be part of adding value to how users interact with information need to pay attention and find ways to adapt.

Originality/value

As new paradigms are created to ensure information exchange is sustainable for everyone, there may be opportunities for libraries. And even if not, libraries may leverage their expertise or relationships to build something that could not be imagined without them. Yet these are only possible if libraries engage.

Abstract

Purpose

The aim of this article is to examine in depth the digital nomad lifestyle and its effects in the context of tourism and to create a perspective for the future by taking into account the findings of the articles in the thematic issue.

Design/methodology/approach

The theme question is examined through a review of the main findings and outcomes of this issue.

Findings

The digital nomad lifestyle stands out as an alternative form of tourism to traditional tourism models. Digital nomads are interested in cultural heritage and are effective in destination marketing just as social media influencers are. Gastronomic preferences and security perceptions of digital nomads play an important role in destination selection. Although digital nomads start out with a desire for independence and freedom, they want to come together with their peers in order to meet their social needs.

Originality/value

This article will serve as a significant resource for understanding the digital nomad lifestyle and for predicting future tourism trends.

Abstract

Purpose

Evaluating the multiphysics performance of an electric motor can be a computationally intensive process, especially where several complex subsystems of the motor are coupled together. For example, evaluating acoustic noise requires the coupling of the electromagnetic, structural and acoustic models of the electric motor. Where skewed poles are considered in the design, the problem becomes a purely three-dimensional (3D) multiphysics problem, which could increase the computational burden astronomically. This study, therefore, aims to introduce surrogate models in the design process to reduce the computational cost associated with solving such 3D-coupled multiphysics problems.

Design/methodology/approach

The procedure involves using the finite element (FE) method to generate a database of several skewed rotor pole surface-mounted permanent magnet synchronous motors and their corresponding electromagnetic, structural and acoustic performances. Then, a surrogate model is fitted to the data to generate mapping functions that could be used in place of the time-consuming FE simulations.

Findings

It was established that the surrogate models showed promising results in predicting the multiphysics performance of skewed pole surface-mounted permanent magnet motors. As such, such models could be used to handle the skewing aspects, which has always been a major design challenge due to the scarcity of simulation tools with stepwise skewing capability.

Originality/value

The main contribution involves the use of surrogate models to replace FE simulations during the design cycle of skewed pole surface-mounted permanent magnet motors without compromising the integrity of the electromagnetic, structural, and acoustic results of the motor.

Abstract

Purpose

This research study aims to minimize autonomous flight cost and maximize autonomous flight performance of a slung load carrying rotary wing mini unmanned aerial vehicle (i.e. UAV) by stochastically optimizing autonomous flight control system (AFCS) parameters. For minimizing autonomous flight cost and maximizing autonomous flight performance, a stochastic design approach is benefitted over certain parameters (i.e. gains of longitudinal PID controller of a hierarchical autopilot system) meanwhile lower and upper constraints exist on these design parameters.

Design/methodology/approach

A rotary wing mini UAV is produced in drone Laboratory of Iskenderun Technical University. This rotary wing UAV has three blades main rotor, fuselage, landing gear and tail rotor. It is also able to carry slung loads. AFCS variables (i.e. gains of longitudinal PID controller of hierarchical autopilot system) are stochastically optimized to minimize autonomous flight cost capturing rise time, settling time and overshoot during longitudinal flight and to maximize autonomous flight performance. Found outcomes are applied during composing rotary wing mini UAV autonomous flight simulations.

Findings

By using stochastic optimization of AFCS for rotary wing mini UAVs carrying slung loads over previously mentioned gains longitudinal PID controller when there are lower and upper constraints on these variables, a high autonomous performance having rotary wing mini UAV is obtained.

Research limitations/implications

Approval of Directorate General of Civil Aviation in Republic of Türkiye is essential for real-time rotary wing mini UAV autonomous flights.

Practical implications

Stochastic optimization of AFCS for rotary wing mini UAVs carrying slung loads is properly valuable for recovering autonomous flight performance cost of any rotary wing mini UAV.

Originality/value

Establishing a novel procedure for improving autonomous flight performance cost of a rotary wing mini UAV carrying slung loads and introducing a new process performing stochastic optimization of AFCS for rotary wing mini UAVs carrying slung loads meanwhile there exists upper and lower bounds on design variables.
