Memory Structures

Call Level Interfaces (CLI) provide a set of functionalities to ease the connection between client applications and relational databases. Among them, the management of data retrieved from databases is emphasized. The retrieved data is kept in local memory structures (LMS) that allow client applications to read it and modify it through protocols. They are row (tuple) oriented and, while being executed, they cannot be preempted to start another protocol. This restriction leads to several difficulties when applications need to deal with several tuples at a time, namely in concurrent environments where several threads need to access to the same LMS instance, each one pointing to a different tuple and executing its particular protocol. To overcome this drawback, a Concurrent Tuple Set Architecture (CTSA) is proposed for LMS. A performance assessment is also carried out. The outcome is the evidence that in concurrent environments, the CTSA significantly improve the overall performance.

Image segmentation is one of the most challenging research fields for both image analysis and interpretation. The applications of image segmentation could be found as the primary step in various computer vision systems. Therefore, the choice of a reliable and accurate segmentation method represents a non-trivial task. Since the selected image segmentation method influences the overall performance of the remaining system steps, sky segmentation appears as a vital step for Unmanned Aerial Vehicle (UAV) autonomous obstacle avoidance missions. In this paper, we are going to introduce a comprehensive literature survey of the different types of image segmentation methodology followed by a detailed illustration of the general-purpose methods and the state-of-art sky segmentation approaches. In addition, we introduce an improved version of our previously published work for sky segmentation purpose. The performance of the proposed sky segmentation approach is compared with various image segmentation approaches using different parameters and datasets. For performance assessment, we test our approach under different situations and compare its performance with commonly used approaches in terms of several assessment indexes. From the experimental results, the proposed method gives promising results compared with the other image segmentation approaches.

In this paper landslide susceptibility mapping and model performance assessment was conducted using three models, logistic regression, GAM, and SVM, in a study area in Shenzhen, China. Ten factors, slope angle, aspect, elevation, plan and profile curvature of the slope, lithology, NDVI, building density, the distance to the river, and the distance to the fault were selected as influencing factors for the landslide occurrences. All three models were trained and the resulting susceptibility maps were created. The performances of the three models were then assessed by AUC values through a 10-fold cross-validation. It could be concluded that in the study area GAM had the best overall performance among the three models, while SVM was better than logistic regression. Based on the derived DPR values, the optimum thresholds between stable areas and risky areas for all three models were also determined.

The Impact

Abstract Background: As the first step towards building a gatekeeping system in China, the governments have introduced a contracted family doctor service (CFDS) policy in primary healthcare (PHC) facilities since 2016. The impact of performance-based salary (PBS) system incentive on performance remained unknown. This study was to examine the association between the PBS adding incentive for CFDS and the performance indicators of diabetes care. Methods: We conducted a cross-sectional study in 72 PHC facilities in 6 cities that piloted the CFDS, extracting 827 PHC health workers and 420 diabetes patients. The PHC health workers’ performance on delivery of diabetes care focused on the continuity and coordination of care. The outcome performance of diabetes care was measured by patients’ utilization of diabetes care and control of blood glucose reported by patients.Results: PHC health workers whose performance on contracted service was included in the overall performance assessment had 0.279 (95% CI 0.031-0.526) more score of the continuity of care, and had 92.6% (OR 1.926, 95% CI 1.160-3.197) higher likelihood of good coordination of care. PHC health workers whose performance linked with increased income were 168.1% (OR 2.681, 95% CI 1.502-4.788) and 78.0% (OR 1.780, 95% CI 1.220-2.597) more likely to have good continuity and coordination of care, respectively. The facility level analysis showed that additional one-point percentage of PHC health workers whose performance on contracted service was included in the overall performance assessment, and additional one-point percentage of whose performance assessment increased their income was associated with 7.192 (OR 8.192, 95% CI 1.903-35.266) times and 52.2% (OR 1.522, 95% CI 1.055-2.196) higher probability of having their patients with control of blood glucose. Additional one-point percentage of PHC health workers whose performance assessment increased their income was associated with 0.559 (95% CI 0.139-0.979) more score on patients’ utilization of diabetes care.Conclusions: Inclusion of the requirements on CFDS into the assessment criteria, and adding the incentives rewarding better performance on contracted family doctors into PBS system for PHC health workers were associated with better delivery process and outcome performance on diabetes care.

Abstract. The measurement of knowledge transfer is considered an important component of the overall performance assessment of research groups. It is, however, not a trivial task, because there is agreement on neither the definition nor on the logical structure of knowledge. In this paper the problems related to the explication of the title term are summarized and the relation between knowledge and information is critically discussed. Open questions with respect to the logical structure of knowledge and its transfer are identified. Requirements to the concept of a knowledge transferometer are developed. Finally the request to scientests to measure their knowledge transfer is critically discussed.
