- Objective: To evaluate patient-reported outcome measures in 2 different multimodal pain rehabilitation programmes and to determine whether outcomes are related to sex or age at 1-year follow-up.Design: Longitudinal retrospective study.Subjects: Patients who had participated in 1 of 2 multimodal pain rehabilitation programmes at 2 rehabilitation centres. A total of 356 women and 83 men, divided into 3 age groups.Methods: Data from the Swedish Quality Registry for Pain Rehabilitation regarding activity and physical functions, pain intensity, health status and emotional functions analysed with descriptive statistics.Results: Significant improvements in activity and physical functions, pain intensity and emotional functions were found in both multimodal pain rehabilitation programmes. Women improved more than men. The older group improved in all emotional functions (depression, anxiety, mental component summary), while the younger group improved only in depression. The intermediate group improved in all variables except anxiety.Conclusion: Patients improved regardless of the design of the multimodal pain rehabilitation programme. Although only small differences were found between men and women and among the 3 age groups in terms of the measured variables, these findings may have clinical relevance and indicate a need to vary the design of the interventions in multimodal rehabilitation programmes for these subgroups.

- BackgroundPatients with chronic pain who live in rural areas often need to travel long distances to participate in multimodal rehabilitation programs. To reduce traveling during the programs, patients sometimes live at a residency close to the clinic and thus far from home.AimsThe aim of this study was to explore how patients with chronic pain experience participation in an Multimodal rehabilitation program while living at a residencyMethodTwelve patients from two specialist clinics in northern Sweden were interviewed about their experiences of participating in multimodal rehabilitation program. The data were analysed qualitatively using a grounded theory method with an emergent design.ResultsThe analyses resulted in a model with the core category “Finding my self-worth” consisting of four categories: “Space for myself”, “Mirroring myself”, “I am of value” and “Dealing with returning to everyday life”. The model illustrates the process whereby participants are given space for themselves and an opportunity to mirror themselves in interaction with other participants. That provided insight about their self-worth which was valuable for return to everyday life at home and work.ConclusionLiving at a residency during multimodal rehabilitation provided added value when patients were relived from the obligations of everyday life at home, and given time for reflection and interaction with others in similar situations. This contributed to awareness of their own value and the necessity of taking care of themselves. This new insight led to increased motivation to act differently at home.

- BackgroundChronic pain is a major and complex health condition associated with reduced work performance. A multimodal rehabilitation programme (MMRP) is a common intervention for chronic pain conditions, the goal being for the person to maintain or return to work.AimTo investigate the multivariate relationships between health-related quality of life, life interference, pain, physiological factors before MMRP and full-time sick leave 1 year after MMRP.Material and MethodsData were collected from the Swedish Quality Registry for Pain Rehabilitation. The study included 284 participants. Separate analyses were performed for women, men and three age groups.ResultsThere were correlations between sick leave, physical functioning, pain duration, health-related quality of life, and self-assessed importance of work before MMRP and sick leave 1 year after MMRP. The patterns of factors associated with full-time sick leave varied for women, men and age groups.ConclusionsThese findings indicate that full-time sick leave for patients with chronic pain is affected by a number of interacting factors. Occupational therapy interventions aiming to develop activity skills in relation to work roles and enable patients to develop skills required to manage the physical, psychological and social demands to return to work or maintain work could be valuable to increase the possibility of attaining a sustainable work situation.

- OBJECTIVES: To investigate the outcomes of a multimodal rehabilitation programme (MMRP) regarding pain intensity, emotional functioning, activity and physical functioning, social response, and health, with regard to sex and age.METHODS: This retrospective longitudinal study was based on data from patients at 2 specialist pain clinics in northern Sweden immediately after MMRP (short-term) and at 1-year follow-up (long-term). Data from 439 patients were analysed according to sex and to age groups 18-30, 31-45 and 46-65 years.RESULTS: The men improved with larger effect sizes (ESs) than women immediately after MMRP. The youngest age group showed improvements with greater ESs compared with the older age groups, both in the short and long term. Social support decreased for both women and men and in all 3 age groups in the long term. Improvements in both the short and long term were found in pain intensity, emotional functioning, and activity and physical functioning, in both women and men, as well as the different age groups.CONCLUSION: Both women and men with chronic pain, and from all of the different age groups, benefitted from MRRP. Since improvements for men were not sustained over time, they may need further support after the programme.

A climate classification for corrosion control in electronic system design

Tidskriftsartikel (refereegranskat)abstract
- Climate factors such as humidity and temperature have a significant impact on the corrosion reliability of electronic products. Given the huge geographical variability in climate conditions globally, a climate classification is a useful tool that simplifies the problem of considering climate when designing electronics packaging. Most current guidelines for electronic product design rely on the Köppen-Geiger classification first developed by Köppen over a century ago. Köppen devised a set of heuristics to separate climates to match different vegetation types. These climate classes are unlikely to be the optimal for electronic product design. This paper presents a new climate classification using parameters important for corrosion reliability of electronics. The classification is based on real climate data measured every 3 h during a 5-year period at over 9000 locations globally. A key step is defining relevant features of climate affecting corrosion in electronics. Features related to temperature are defined, but also the amount of time that the difference between Temperature and Dew Point is less than 1, 2 or 3 ℃. These features relate to the risk of condensation in electronic products. The features are defined such that diurnal, seasonal and yearly variation is taken into account. The locations are then clustered using K-means clustering to obtain the relevant climate classes. This data-driven classification, based on key features for corrosion reliability of electronics, will be a useful aid for product design, reliability testing and lifetime estimation.

Harvest time prediction for batch processes
- 2018

- Batch processes usually exhibit variation in the time at which individual batches are stopped (referred to as the harvest time). Harvest time is based on the occurrence of some criterion and there may be great uncertainty as to when this criterion will be satisfied. This uncertainty increases the difficulty of scheduling downstream operations and results in fewer completed batches per day. A real case study is presented of a bacteria fermentation process. We consider the problem of predicting the harvest time of a batch in advance to reduce variation and improving batch quality. Lasso regression is used to obtain an interpretable model for predicting the harvest time at an early stage in the batch. A novel method for updating the harvest time predictions as a batch progresses is presented, based on information obtained from online alignment using dynamic time warping.

- A novel data driven approach to batch process monitoring is presented, which combines the k-Nearest Neighbour rule with the dynamic time warping (DTW) distance. This online method (DTW-NN) calculates the DTW distance between an ongoing batch, and each batch in a reference database of batches produced under normal operating conditions (NOC). The sum of the k smallest DTW distances is monitored. If a fault occurs in the ongoing batch, then this distance increases and an alarm is generated. The monitoring statistic is easy to interpret, being a direct measure of similarity of the ongoing batch to its nearest NOC predecessors and the method makes no distributional assumptions regarding normal operating conditions. DTW-NN is applied to four extensive datasets from simulated batch production of penicillin, and tested on a wide variety of fault types, magnitudes and onset times. Performance of DTW-NN is contrasted with a benchmark multiway PCA approach, and DTW-NN is shown to perform particularly well when there is clustering of batches under NOC.

Selecting local constraint for alignment of batch process data with dynamic time warping
- 2017

- There are two key reasons for aligning batch process data. The first is to obtain same-length batches so that standard methods of analysis may be applied, whilst the second reason is to synchronise events that take place during each batch so that the same event is associated with the same observation number for every batch. Dynamic time warping has been shown to be an effective method for meeting these objectives. This is based on a dynamic programming algorithm that aligns a batch to a reference batch, by stretching and compressing its local time dimension. The resulting ”warping function” may be interpreted as a progress signature of the batch which may be appended to the aligned data for further analysis. For the warping function to be a realistic reflection of the progress of a batch, it is necessary to impose some constraints on the dynamic time warping algorithm, to avoid an alignment which is too aggressive and which contains pathological warping. Previous work has focused on addressing this issue using global constraints. In this work, we investigate the use of local constraints in dynamic time warping and define criteria for evaluating the degree of time distortion and variable synchronisation obtained. A local constraint scheme is extended to include constraints not previously considered, and a novel method for selecting the optimal local constraint with respect to the two criteria is proposed. For illustration, the method is applied to real data from an industrial bacteria fermentation process.
