In: Energy. - : Elsevier BV. - 0360-5442 .- 1873-6785. ; 49:1, s. 204-210

Journal article (peer-reviewed)abstract
- This paper presents an innovative hybrid approach for the estimation of the solar global radiation. New prediction equations were developed for the global radiation using an integrated search method of genetic programming (GP) and simulated annealing (SA), called GP/SA. The solar radiation was formulated in terms of several climatological and meteorological parameters. Comprehensive databases containing monthly data collected for 6 years in two cities of Iran were used to develop GP/SA-based models. Separate models were established for each city. The generalization of the models was verified using a separate testing database. A sensitivity analysis was conducted to investigate the contribution of the parameters affecting the solar radiation. The derived models make accurate predictions of the solar global radiation and notably outperform the existing models.

Journal article (peer-reviewed)abstract
- This paper focuses on data modeling for traceability of material/work flow in informationlayer of manufacturing control system. The model is able to trace all associated data throughout theproduct manufacturing from order to final product. Dynamic data processing of Quality and Purchaseactivities are considered in data modeling as well as Order and Operation base on lots particulars. Themodeling consisted of four steps and integrated as one final model. Entity-Relationships Modeling asdata modeling methodology is proposed. The model is reengineered with Toad Data Modeler softwarein physical modeling step. The developed model promises to handle fundamental issues of atraceability system effectively. It supports for customization and real-time control of material in flowin all levels of manufacturing processes. Through enhanced visibility and dynamic store/retrieval ofdata, all traceability usages and applications is responded. Designed solution is initially applicable asreference data model in identical lot-base traceability system.

Providing fairness to mobile workforces in an automated task allocation process : A semantic multi-agent approach
- 2012
-
In: American Journal of Applied Sciences. - : Science Publications. - 1546-9239 .- 1554-3641. ; 9:7, s. 1055-1062
-
Journal article (peer-reviewed)abstract
- Problem statement: Mobile Workforces (MW) unlike computational resources of an automated system are active but not passive entities. Therefore, an automated resource allocation system that deals with MWs should assign tasks to them fairly and in a comparatively equal manner. An unfair task allocation in a group will cause dissatisfaction, which in turn demotivates MWs who are supposed to work as a team. Approach: In an automated Mobile Workforce Brokering System (MWBS) tasks are automatically assigned to MWs at Run-Time phase of the system's run. However, the environmental risks specifically risk of disconnection disrupts the task allocation process. Disconnection causes unfair task allocation when an MW must carry the next upcoming task according to a rotator work schedule, but he is disconnected. In this situation another MW has to perform the task in order to satisfy a pre-planned daily workload. Results: In this study we explore through the Run-Time phase of MWBS and explain how its underpinning ontology-driven coordination model tackles the risk of disconnection and improves the fairness in the task allocation process. Conclusion: Moreover, fairness rates in task allocation processes are compared between an existing system and MWBS and improvement in fairness rate is shown and analyzed for 4 consecutive periods (months) of the system's run

Engaged lifestyle and episodic and semantic memory : longitudinal studies from the betula project
- 2012
-
Doctoral thesis (other academic/artistic)abstract
- This dissertation examines whether some aspects of engaged lifestyle, marital status and leisure activity, influence memory performance in adulthood and old age. Direct effects and indirect effects, via health, are investigated. All the studies in the dissertation examine participants in the Betula project, aged 35 to 85 years. Study I investigates whether there are reliable effects of marital status on memory function in a large sample of participants in adulthood and old age. The results demonstrate that marriage has an influence on some specific types of memory functions. They show that there are significant differences between married and single individuals in episodic memory, but not in semantic memory. Also, the extent of decline in episodic memory was found to be significantly larger for singles and widowed individuals than for married people over five years. Study II examines the relationships between different types of social and cognitive activities and episodic and semantic memory. The results show that a unidirectional effect of social activity on episodic memory was detectable on all test occasions. Also, episodic memory predicted change in cognitive activity during all test waves. However, there were no significant effects with regard to semantic memory and leisure activity in either direction. Study III explores longitudinally whetherengaged lifestyle, including marriage and leisure activity, directly affects memory performance, or whether the effect is mediated by health. The overall results demonstrate that marriage predicts episodic memory function directly. Leisure activity can also predict episodic memory performance ten years later, but indirectly via health. An active and engaged lifestyle can protect people against memory decline. The positive impact of engaged lifestyle on memory performance is discussed in terms of cognitive reserve theory, and in relation to the decrease in distress afforded by social support from other people.

Journal article (peer-reviewed)abstract
- The present study examined the relationships between different types of activities, cognitive and social, and episodic memory and semantic memory. A total of 794 adult men and women from five age cohorts (aged 65-85 at baseline), participating in the longitudinal Betula project on aging, memory, and health, were included in the study. The participants were studied over 10 years (1995-2005) in threes waves. Recognition and recall were used as episodic memory tasks, and knowledge and verbal fluency as semantic memory tasks. The results, after controlling for age, gender, education and some diseases, including heart disease and hypertension, as covariates, showed unidirectional effects of social activity on episodic memory on all test occasions (β = .10). Also, episodic memory predicted change in cognitive activity for all test waves (β = .21-.22). The positive role of social activity on memory function is discussed in terms of cognitive reserve theory, and the reduction of stress. It also seems that episodic memory performance is a predictor of cognitive activity in old people. However, the opposite direction does not hold true.

In: Scandinavian Journal of Psychology. - : John Wiley & Sons. - 0036-5564 .- 1467-9450. ; 53:1, s. 1-8
-
Journal article (peer-reviewed)abstract
- The present study examined the influences of marital status on different episodic and semantic memory tasks. A total of 1882 adult men and women participated in a longitudinal project (Betula) on memory, health and aging. The participants were grouped into two age cohorts, 35–60 and 65–85, and studied over a period of 5 years. Episodic memory tasks concerned recognition and recall, whereas semantic memory tasks concerned knowledge and fluency. The results showed, after controlling for education, some diseases, chronological age and leisure activity as covariates, that there were significant differences between married and single individuals in episodic memory, but not in semantic memory. Married people showed significantly better memory performances than singles in both subsystems of episodic memory, that is, recall and recognition. Also, the rate of decline in episodic memory was significantly larger for singles and widowed than other groups over the 5-year time period in both age groups. The findings demonstrate that the positive relation found between marriage and health can be extended to the relation between marriage and cognitive performance. This effect might be explained by the role played by cognitive stimulation in memory and cognition.
