Prediction of structural damage prior to earthquake occurrence provides an early warning for stakeholders of building such as owners and urban managers and can lead to necessary decisions for retrofitting of structures before a disaster occurs, legislating urban provisions of execution of building particularly in earthquake prone areas and also management of critical situations and managing of relief and rescue. For proper prediction, an effective model should be produced according to field data that can predict damage degree of local buildings. In this paper in accordance with field data and Fuzzy logic, damage degree of building is evaluated. Effective parameters of this model as an input data of model consist of height and age of the building, shear wave velocity of soil, plan equivalent moment of inertia, fault distance, earthquake acceleration, the number of residents, the width of the street for 527 buildings in the city. The output parameter of the model, which was the damage degree of the buildings, was also classified as five groups of no damage, slight damage, moderate damage, extensive damage, and complete damage. The ranges of input and output classification were obtained based on the supervised center classification (SCC-FCM) method in accordance with field data.

Binding Agreement

The BOT (Build Operate Transfer) Agreement between Bogor Municipal Government and PT Pancakarya Grahatama Indonesia is an agreement to optimize Baranangsiang terminal assets as stated in the agreement Number: 601 / Perj.418-BPKAD / 2012 / Number: 005 / PGI / DIR / VI / 2012 . Until now, the agreement of both parties has not been able to be considered because of the change of authority of the terminal which formerly the authority of the City Government of Bogor to switch to the Central Government, resulting problems Whether the Government / Mayor Bogor can cancel the unilateral agreement BOT in the construction of Terminal Baranangsiang viewed from the point Civil Code? The research method used is normative legal research method supported by interview and field data. Based on the analysis that the BOT agreement between Bogor City Government and PT Pancakarya Grahatama is a valid and binding agreement between both parties and can not be canceled unilaterally by Bogor City Government, although there are new regulations that change the authority of terminal A Baranangsiang become the authority of Central Government . The Agreement may be canceled if it violates Article 1320 of the Criminal Code or violates the subjective and objective terms of the validity of the agreement. When the agreement is mutually agreed upon by both parties, the agreement must continue and act as a binding law as regulated in Article 1338 of the Criminal Code. Bogor City Government should immediately provide certainty to the PT Pancakarya Grahatama Indonesia for Baranangsiang terminal revitalization project can be immediately realized and need a revision (adedendum) agreement between the Government of Bogor City with PT Pancakarya Grahatama Indonesia related to changes in authority of terminal A Baranangsiang between PT. PGI with the Central Government.

In 5·12 Wenchuan earthquake, most of the buildings were damaged at different degrees in Mianyang. To analysis seismic damage of RC frame structure building, and investigate its reinforcement situation，the results show that: For destruction of frame column or bottom frame structure column, enlarge section method is used mostly for reinforcement in civil engineering；To serious damage of affiliated structure such as filler wall and Parapet, most of them will be demolished and built again, and add constructional column; To the situation of concrete bottom plate with crack, paste carbon fiber sheet or bottom plant steel was used depending on the structural damage degree, and jet concrete for strengthening.

Abstract The Department of Computer Integrated Design (DiK) at the TU Darmstadt deals with the Digital Twin topic from the perspective of virtual product development. A concept for the architecture of a Digital Twin was developed, which allows the administration of simulation input and output data. The concept was built under consideration of classical CAE process chains in product development. The central part of the concept is the management of simulation input and output data in a simulation data management system in the Digital Twin (SDM-DT). The SDM-DT takes over the connection between Digital Shadow and Digital Master for simulation data and simulation models. The concept is prototypically implemented. For this purpose, real product condition data were collected via a sensor network and transmitted to the Digital Shadow. The condition data were prepared and sent as a simulation input deck to the SDM-DT in the Digital Twin based on the product development results. Before the simulation data and models are simulated, there is a comparison between simulation input data with historical input data from product development. The developed and implemented concept goes beyond existing approaches and deals with a central simulation data management in Digital Twins.

The Sardis excavation sector known as MMS was a center of habitation for over a millennium. Archaic houses built near the great mudbrick fortification were succeeded by scattered Hellenistic and Roman dwellings, to be followed in late antiquity by imposing residences of complex plan and ambitious decoration. Like other parts of the city, these houses saw extensive structural damage in the early A.D. 600s. Raised floors, flimsy partitions and makeshift hearths are among the few signs of lingering occupation.1

AbstractResistive stresses and velocities at depth are calculated along the Byrd Station Strain Network, Antarctica, using field data. There are found to be large longitudinal variations in basal drag and this result is little affected by errors in the input data or by uncertainties in the constitutive relation for ice. Basal drag varies by a factor of about 2 along the strain network, and is usually equal to the driving stress to within 10–20%. Sites of high drag are not always correlated with basal topographic highs, indicating that some process such as basal water drainage is involved in controlling the friction at the bed. Basal sliding velocities are very sensitive to errors in measured surface velocities and the rate factor in Glen’s flow law. As a result, calculated sliding velocities are much less reliable than deep stresses, and need to be interpreted with caution.

In order to explore the effective damage identification method for structure, the structural vibration signal is directly correlation dimension analyzed according to fractal theory, and structural damage is identified by measuring the singularity in system output, then the method for structural damage identification based on correlation dimension of vibration response is proposed. The damage analysis results of a simply supported beam demonstrate that, the proposed method can accurately detect single and multi different degree damage’s location of beam structure, and alteration of correlation dimension will increase along with the damage degree

The paper deals with selected approaches which unite several correlation analysis principles. Field data very often has various forms and contents. The comparison of different approaches will help to determine more precisely which correlation analysis is better for assessing input and output data. In this paper we introduce several correlation principles which can help to select the most suitable correlation approach. We present a traditional correlation analysis and compare it with Pearson and Spearman correlation coefficients. The value of our article lies in comparing several different approaches of the correlation analysis in which the oil field data from diesel combustion engine are used

Due to structural damage, decimation of skilled laboratory staff, and loss of critical supplies, laboratory capabilities after 26 December were essentially nil in Banda Aceh, the city centre of Aceh Province. On 15 January 2005, staff from NIHRD and NAMRU-2 were jointly given the task of establishing a reference laboratory on the grounds of the Aceh provincial health laboratory unit (Labkesda Aceh) in response to the direct need for laboratory resources. This reference laboratory, known as L3, was funded by USAID.
