Verifying for Compliance to Data Constraints in Collaborative Business Processes.

Production processes are nowadays fragmented across different companies and organized in global collaborative networks. This is the result of the first wave of globalization that, among the various factors, was enabled by the diffusion of Internet-based Information and Communication Technologies (ICTs) at the beginning of the years 2000. The recent wave of new technologies possibly leading to the fourth industrial revolution – the so-called Industry 4.0 – is further multiplying opportunities. Accessing global customers opens great opportunities for organizations, including small and medium enterprises (SMEs), but it requires the ability to adapt to different requirements and conditions, volatile demand patterns and fast-changing technologies. Regardless of the industrial sector, the processes used in an organization must be compliant to rules, standards, laws and regulations. Non-compliance subjects enterprises to litigation and financial fines. Thus, compliance verification is a major concern, not only to keep pace with changing regulations but also to address the rising concerns of security, product and service quality and data privacy. The software, in particular process automation, used must be designed accordingly. In relation to process management, we propose a new way to pro-actively check the compliance of current running business processes using Descriptive Logic and Linear Temporal Logic to describe the constraints related to data. Related algorithms are presented to detect the potential violations

GÜNEYDOĞU AKDENİZ'DE ÖNEMLİ TEKTONİK HATLAR

İnceleme alanında önemli tektonik hatları ortaya çıkarmak amacıyle Bouguer anomalilerine iki farklı istatistik trend analizi uygulanmıştır. Birincisi basit grafik-sayısal yöntemdir. Bu yöntemde Bouguer anomalilerinin doğrudan kullanılması tektonik hatların ortaya çıkarılmasında güvenilir bir yoldur. İkincisi; yerkabuğunun farklı derinliklerinde önemli değişmeleri ortaya çıkarmak amacıyle kalıntı (residual) alanlara uygulanan iki boyutlu otokovarians yöntemidir. İki yöntemin uygulamalarının ayrıntılı irdelenmesi sonucunda, yazarlar, yedi önemli hat tespit etmişlerdir. Bunlar; D-B. K60°DG60°B, K60°B-G60°D, K40°D-G40°B, K30°B-G30°D, K-G ve K20°D-G20°B. K60°B-G60°-D ve K20°D-G20°B yönlerinin yüzeye yakın kayaçları etkilediği tahmin edilirken, diğer yönler, kabuğu derinliklerine kadar etkilemişlerdir

Displacement pattern of the Sinai area: first results from GPS

A network of 12 GPS stations, seven of them located on the Sinai peninsula, another four on the west shore of the Gulf of Suez and the last on the inner Gulf of Aqaba (ELAT, Israel) was analyzed twice, processing GPS data recorded in November 1997 and in May 1998. A rigorous statistical analysis based on the F (Fisher) test applied on the detected coordinate differences showed significant displacement at all the sites located on the Sinai peninsula with respect to the others. The planar displacements of the Sinai sites are of the order of 1.5 cm in the considered time span. The agreement exhibited by the Sinai displacements, both in magnitude and azimuth, taking into account the associated errors, provides evidence that the Sinai peninsula behaves like a rigid block or sub-plate with respect to the African plate. A raw estimate of its mean velocity gives about 3.0 cm/yr and 208° of azimuth. Although it is not possible to draw exhaustive conclusions on the geodynamics of the Suez and Sinai areas and the lack of GPS data on the Arabian peninsula makes the analysis incomplete, our results agree well with the left lateral motion of the Aqaba-Levant fault. Moreover, no evidence of extension is detected for the Gulf of Suez, but rather unexpectedly, a contraction component seems to be found by the present work

Stress level estimation for the ground beneath the 15th of May city buildings, Helwan, Cairo, Egypt

The quarry blasting is one of the artificial explosions that produces stresses in the ground and may have a great effect on the near foundations. The estimation of the stress level either in the weathering layer or the bedrock is necessary for the safety of the existing buildings near the quarries. Cement Companies has been in operation since 1956 close to Helwan City, Egypt. Since then, new buildings and new communities were established in the area such as the City of 15th of May. For the safety of these buildings, detailed and continuous monitoring of the peak particle velocity of the quarry blasting operations was carried out since January 1997 till September 2000. The maximum values of the stress level for the weathering layer has been found smaller than that for the bedrock for both of the P- and S-waves. The damage observed in the buildings close to the quarry blasting operations, indicates that these stress levels are high

Magma intrusion in the upper crust of the Abu Dabbab area, south east of Egypt from vp and vp/vs tomography,

3-DimagesofP-wavevelocityandVp/Vsratiohavebeenproduced for the upper crust of the Abu Dabbab area, North Mars Alam city. The inver- sion of local travel times of high quality data recorded at eleven mobile seimic stations around the study area is carried out. The best, in the least-squares sense, 1-D Vp model and the average value of Vp/Vs (1.72) were computed as prerequisites of the 3-D inversion that reaches a depth of 14 km. From the 3-Dmodel it is evident that the distributions of Vp and Vp/Vs are characterized by marked lateral and vertical variations delineating structural heterogeneities. Due to the presence of a thin layer of sedimentary rocks saturated with surface water, low P-wave velocity and high Vp/Vs values are noticed near the surface. At greater depths, high Vp and low Vp/Vs zones may indicate crustal rocks with relatively higher rigidity and brittle behavior, while high Vp/Vs and low Vp may identify zones of relatively softer rocks, with ductile behavior. Low P-wave velocity values are observed at the intersections among the faults. A possibility of some magma intrusion could be associated with the high Vp/Vs values which form an elongated anomaly, in the central part of the study area, which extends from a depth of 12 km to about 1-2 km of depth. If the obtained 3-D model is used in the relocation of selected events, they turn out to be strongly clustered in correspondence with the high velocity anomalies detected in the central part of the study area. Most of the seismicity tends to occur at the boundaries between the high and low velocity anoma- lies and at pre-existing weakness zones, i.e. the areas of intersection among different faults. The occurrence of the seismic activity in the vicinity of low velocity anomalies and at the boundary between velocity contrast could also be explained by the occurrence of serpentinization processes in the crust of the study area
