The current practice of controller development for flexible robotic systems generally focuses on one-link robotic arms and is valid for small oscillations. This work addresses the control of n-link, serial, spatial robotic systems modeled with m1 joint and m2 link flexibilities such that n≥m1+m2. System compliance is modeled by local springs and nonactuated prismatic and revolute type pseudo joints. The coupled, nonlinear, error-driven system equations are derived for the complete model without linearization or neglecting certain terms. For this system, the complete accessibility of vibrations is studied by orthogonal projections. It is shown that under some configurations of a robotic system, the induced oscillations may not be accessible to the controller. Given accessibility, the controller developed in this work assures the global asymptotic stability of the system. Example numerical simulations are presented based on the model of a six-degree-of-freedom Cincinnati Milacron T3-776 industrial robot. One example models the system compliance in four joints, while another case study simulates four lateral link oscillations. These examples show that this controller, even under inaccurate payload description, eliminates the oscillations while tracking desired trajectories.

This research investigates how contingency is currently calculated in project budgets within the building industry. This is an important aspect to consider as a large proportion of construction projects are significantly over-budget. The study presents three non-simulation methods and one simulation method for calculating cost contingency following the results of a forthcoming journal paper. These methods are applied against a case study project in attempt to highlight the most reliable method, and to create a methodology that will be useful to the industry. This paper identifies that the traditional fixed percentage approach is not sufficient and suggests that this could be one of the main reasons why construction projects are over budget. While it is unclear which method is the most reliable, this study provides a focus for future research into reliability and utilisation of contingency methods in the building industry. The research demonstrates that current practice needs to change to reduce the large number of construction projects that run over budget.

Malaysia recorded 8904 coronavirus disease (COVID-19) cases and 124 deaths as of 27 July 2020. Globally, everyday there are thousands of new cases of COVID-19 being recorded. Due to the high number of infections globally and nationwide the increase in the amount of clinical waste (CW) generation was expected. Malaysia has reported a 27% (by weight) increase in the generation of CW which was mostly attributed to COVID-19 related waste. This article presents the impacts of COVID-19 in waste generation, policy and regulation of CW management (CWM) in Malaysia and a case study on the CWM at a selected hospital used as a COVID-19 focal point. The current practice of CWM due to COVID-19 related cases follows the existing policy and legislation of CWM detailed in the Schedule Waste Regulation (2005), Environmental Quality Act, 1974, and with the standard operating procedure provided by the Ministry of Health, Malaysia. The case study conducted through survey and questionnaire interviews revealed that the CWM in government hospitals followed existing guidelines for CWM for COVID-19 waste, with some additional precautions and rules by the waste management contractors.

This paper presents a methodology to solve a special case of the vehicle routing problem (VRP) called the heterogeneous fleets VRP with excessive demand of the vehicle at the pickup points, and the longest time constraint (HFVRP-EXDE-LTC). We developed two metaheuristics—a differential evolution (DE) algorithm and an adaptive large neighborhood search (ALNS)—to solve the problem. These two proposed methods have been designed to effectively solve a special case of VRP. From the computational results, we can see that the proposed heuristics outperformed the best practices that are currently in use. The DE yielded a 9.78% lower cost than that of the current practice (757,250 baht per year), while ALNS generated a 10.89% (906,750 baht per year) lower cost than that of current practice. Comparing the proposed heuristics, ALNS achieved a 1.01% lower cost than that of DE, as ALNS had a better mechanism that was designed to escape from the local optimal.

Purpose This paper aims to describe the impact of the COVID-19 pandemic on a prison-based therapeutic community (TC). Design/methodology/approach The paper takes the form of a case study where the authors reflect on their current practice, using the findings of research on social isolation and the overarching TC principles to explore the effect of the pandemic on the TC at HMP Grendon. The authors consider how the residents and staff adjusted to the change as the parameters changed when the social distancing rules were imposed and how they adapted to the prolonged break to therapy. Sections in the paper were written by a resident and an operational member of staff. The authors conclude with their thoughts on how to manage the consequences the lockdown has brought and start to think about what returning to “normality” might mean. Findings The paper describes the adjustments made by the residents and staff as the UK Government imposed the lockdown. The authors, including a resident and an operational member of staff comment on the psychological and practical impact these adjustments had. The thought is given to the idea of “recovery”, returning to “normality” and how this study can be best managed once restrictions are lifted. Research limitations/implications At the time of writing, there are no confirmed cases of COVID-19 at HMP Grendon. The measures and commitment from all staff and residents in the prison to keep the prison environment safe may in part account for this. This paper explores the effects of lockdown on the emotional environment in a TC and highlights the consequences that social isolation can have on any individual. To the authors’ knowledge, there is currently no research undertaken on the impact of lockdown/social isolation on a TC. This research would be useful, as the authors postulate from reflections on current practice that the effects of the lockdown will be greater in a social therapy environment. Originality/value HMP Grendon started in 1962, as this time there have been no significant events that have meant the suspension of therapy for such a sustained period. It is, therefore, important that the impact of such is considered and reflected upon.

AbstractAdopting design thinking and innovation-oriented approaches in organizations is crucial but not always simple. New practices of collaboration, user-orientedness and exploration require a compatible culture to be successfully integrated into product development. This paper presents a case study based on 12 interviews of employees and managers in a large Finland-based technology company, introducing new ways of working to product development. Silos, focusing on inventions, and a lack of resources for exploration were highlighted as key challenges in transitioning from incremental development to innovations. Perhaps counterintuitively, introducing new ways of working requiring a collaborative culture - the most widely recognized shortcoming in the current practice in the case - were best received, and support and feedback could be found for pilot projects in these arenas. When the gap between the practice and culture was smaller, change efforts could perhaps be more challenging, as there was less of a consensus on a need to change. The results suggest than developers need not automatically shy away from piloting new ways of working even when existing cultures are not compatible.

With the advancement of nanobiotechnology, eco-friendly approaches of plant-mediated silver nanomaterial (AgNP) biosynthesis have become more attractive for biomedical applications. The present study is a report of biosynthesizing AgNPs using Chlorophytum borivilianum L. (Safed musli) callus extract as a novel source of reducing agent. AgNO3 solution challenged with the methanolic callus extract displayed a change in color from yellow to brown owing to the bioreduction reaction. Further, AgNPs were characterized by using UV–visible spectrophotometry, X-ray Diffraction (XRD), Atomic Force Microscopy (AFM), and Fourier Transform Infrared Spectroscopy (FTIR). UV–vis spectrum revealed the surface plasmon resonance property of AgNPs at around 450 nm. XRD pattern with typical peaks indicated the face-centered cubic nature of silver. AFM analysis confirmed the existence of spherical-shaped and well-dispersed AgNPs having an average size of 52.0 nm. Further, FTIR analysis confirmed the involvement of different phytoconstituents of the callus extract role in the process of bioreduction to form nanoparticles. The AgNPs were more efficient in inhibiting the tested pathogenic microbes, namely, Pseudomonas aeruginosa, Bacillus subtilis, Methicillin-resistant Escherichia coli, Staphylococcus aureus, and Candida albicans compared to callus extract. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay confirmed the cytotoxic property of AgNPs against human colon adenocarcinoma cell line (HT-29) in a dose-dependent manner. At higher concentrations of 500 μg/mL AgNPs, the cell viability was observed to be only 7% after 24 hours with IC50 value of 254 μg/mL. Therefore, these AgNPs clearly endorse the manifold potential to be used in various biomedical applications in the near future.
