In living cells, molecular motors convert chemical energy into mechanical work. Its thermodynamic energy efficiency, i.e. the ratio of output mechanical work to input chemical energy, is usually high. However, using two-state models, we found the motion of molecular motors is loosely coupled to the chemical cycle. Only part of the input energy can be converted into mechanical work. Others is di...

The frequency content and time duration of earthquakes are as effective the peak ground acceleration on structural damage. Therefore, using rapid seismic vulnerability assessment methods that consider earthquake history is noticeable. Kermanshah a historical city generally affected by far-field earthquakes. it necessary to effect low-frequency shocks in evaluating buildings this city. Herein, h...

Once disregarded as noise, scattered seismic waves are finding increasing application in subsurface imaging. This sea change is driven by the increasing density and quality of seismic recordings and advances in waveform modeling which, together, are allowing seismologists to exploit their unique properties. In addition to extensive application in the energy exploration industry, seismic scatter...

Seismic data consist of traces, which contain information about a seismic event, but in some period of time the traces may be just noise. A trace which contains seismic information, is called a seismic signal. Seismic signals consist of several typically short energy bursts, called phases, exhibiting several patterns in terms of dominant frequency, amplitude and polarisation. Amongst others, a ...

1. INTRODUCTION Vacuum selection is one of the most important issues in string/M theory. The standard cartoon of string vacua (see figure 1.1) showing all the ten dimensional perturbative string asymptopia together with the eleven-dimensional limit, refers to solutions with a large number of supersymmetries, and flat directions (moduli) in the effective action. 11d I IIB heterotic IIA Figure 1....

In accordance with the Seismo-Geothermics theory about methods of intracrustal strong earthquake and volcano prediction, we use the ANSS earthquake catalogue from the Northern California earthquake data center and the EMSC earthquake catalogue from the European-Mediterranean Seismological Centre to study the seismic activities of the Turkish Branch Seismic Cone in the Mediterranean Seismic Cone...

Fatigue damage is considered to be one of the most critical phenomenon, contributing to the failure of an aircraft structure. Understanding the fatigue mechanism is essential for considering the different technical conditions that influence the fatigue life of structures. In recent years, fatigue tests are accelerated in order to reduce the testing time of materials/structures being developed, ...

This research focused on developing reliability-based seismic retrofit assessment procedures for highway bridge columns. Fragility curves were developed to assess the relative performance of various retrofit methods considering several limit states. Analytical fragility curves are developed from scaled earthquake records and structural response models. A simplified, single-degree-of-freedom (SD...

We analyzed four pairs of a large (Mw "'6) and a small (Mw "' 3.5 to 4) shallow strike-slip earthquakes to investigate the scale-dependence. of the seismic energy-tomoment ratio, an important macroscopic parameter which reflects the basic physical process of seismic slip. These earthquakes occurred in the south-western part of Japan, and high-quality close-in records (epicentral distance< 50 km...

A major concern of current and future on-chip systems is the thermal problem i.e. electrical energy is dissipated leading to high chip temperatures. Short term effects may include transient malfunctioning whereas long-term effects may lead to deteriorating functionality (e.g. increased signal travel times) or to irreversible damage due to, for example, electro-migration. The problem worsens wit...
