The main aim of this paper is to present how to refine software logical architectures by application of a recursive model-based transformation approach called 4SRS (four step rule set). It is essentially based on the mapping of UML use case diagrams into UML object diagrams. The technique is based on a sequence of steps that are inscribed in a tabular representation that is used to derive the software architecture for a focused part of the global system.

Anomalies on road pavement cause discomfort to drivers and passengers, and may cause mechanical failure or even accidents. Governments spend millions of Euros every year on road maintenance, often causing traffic jams and congestion on urban roads on a daily basis. This paper analyses the difference between the deployment of a road anomalies detection and identification system in a “conditioned” and a real world setup, where the system performed worse compared to the “conditioned” setup. It also presents a system performance analysis based on the analysis of the training data sets; on the analysis of the attributes complexity, through the application of PCA techniques; and on the analysis of the attributes in the context of each anomaly type, using acceleration standard deviation attributes to observe how different anomalies classes are distributed in the Cartesian coordinates system. Overall, in this paper, we describe the main insights on road anomalies detection challenges to support the design and deployment of a new iteration of our system towards the deployment of a road anomaly detection service to provide information about roads condition to drivers and government entities.

Abstract-This paper presents the first developments of an industrial network laboratory prototype. In the Automation Laboratory several kits have been implemented for local and remote control tests. The approach includes the design and implementation of an industrial network where the common communications protocols can be tested: the Automation Network Locker (ANL). To facilitate the monitoring and control of the network, WALC (Web Assisted Laboratory for Control Engineering on-line Education) interface platform was developed. This allows the remote monitoring and control of the pedagogic kits to complement the teaching/learning automation to undergraduate engineering students. The security of network access is also taken into account in order to limit and control the number of users that can access it. An on-line questionnaire accessed at the end of each semester, allows an actualization and to follow the students' feedback.

Abstract. This paper presents a new algorithm for distributed garbage collection and outlines its implementation within the Network Objects system. The algorithm is based on a reference listing scheme augmented by partial tracing in order to collect distributed garbage cycles. Our collector is designed to be exible thereby allowing e ciency, expediency and fault-tolerance to be traded against completeness. Processes may b e dynamically organised into groups, according to appropriate heuristics, in order to reclaim distributed garbage cycles. Unlike previous groupbased algorithms, multiple concurrent distributed garbage collections that span groups are supported: when two collections meet they may either merge, overlap or retreat. The algorithm places no overhead on local collectors and suspends local mutators only brie y. P artial tracing of the distributed graph involves only objects thought t o be part of a garbage cycle: no collaboration with other processes is required.

Fifty canine mammary gland tumours (CMGT) (18 benign and 32 malignant) were studied by immunohistochemical detection of active caspase-3 and Ki-67 antigens in order to determine their association with several clinicopathological parameters. The percentage of caspase-3 positive cells was significantly higher in benign tumours as compared to their malignant counterparts (P ≤ 0.001). In the group of malignant tumours there was no significant association between active caspase-3 and the clinicopathological variables considered. The percentage of Ki-67 positive cells was significantly higher in malignant tumours compared to the benign ones (P ≤ 0.001). In the group of malignant tumours, Ki-67 expression showed a statistically significant association with tumour size (P = 0.025), histological type (P = 0.010), mitotic grade (P ≤ 0.001), nuclear grade (P = 0.025), differentiation grade (P = 0.004), histological grade of malignancy (P = 0.002), and presence of metastases in regional lymph nodes (P = 0.025). Furthermore, this study revealed a negative correlation between the percentages of active caspase-3 and Ki-67 (r = -0.39; P = 0.04). Thus, our results suggest a loss of balance between cell death and cell division in CMGT.

Mobile payments still remain essentially an emerging technology, seeking to fill the gap between the envisioned potential and widespread usage. In this paper, we present an integrated mobile service solution based on the near field communication (NFC) protocol that was developed under a research project called MobiPag. The most distinctive characteristic of Mobipag is its open architectural model that allows multiple partners to become part of the payment value-chain and create solutions that complement payments in many unexpected ways. We describe the Mobipag architecture and how it has been used to support a mobile payment trial. We identify a set of design lessons resulting from usage experiences associated with real-world payment situations with NFC-enabled mobile phones. Based on results from this trial, we identify a number of challenges and guidelines that may help to shape future versions of NFC-based payment systems. In particular, we highlight key challenges for the initial phases of payment deployments, where it is essential to focus on scenarios that can be identified as more feasible for early adoption. We also have identified a fundamental trade-off between the flexibility supported by the Mobipag solution and the respective implications for the payment process, particularly on the users' mental model.
