Повний текст джерелаThe seismicity of the Dead Sea fault zone (DSFZ) during the last two millennia is characterized by a number of damaging and partly devastating earthquakes. These events pose a considerable seismic hazard and seismic risk to Syria, Lebanon, Palestine, Jordan, and Israel. The occurrence rates for large earthquakes along the DSFZ show indications to temporal changes in the long-term view. The aim of this thesis is to find out, if the occurrence rates of large earthquakes (Mw ≥ 6) in different parts of the DSFZ are time-dependent and how. The results are applied to probabilistic seismic hazard assessments (PSHA) in the DSFZ and neighboring areas. Therefore, four time-dependent statistical models (distributions), including Weibull, Gamma, Lognormal and Brownian Passage Time (BPT), are applied beside the exponential distribution (Poisson process) as the classical time-independent model. In order to make sure, if the earthquake occurrence rate follows a unimodal or a multimodal form, a nonparametric bootstrap test of multimodality has been done. A modified method of weighted Maximum Likelihood Estimation (MLE) is applied to estimate the parameters of the models. For the multimodal cases, an Expectation Maximization (EM) method is used in addition to the MLE method. The selection of the best model is done by two methods; the Bayesian Information Criterion (BIC) as well as a modified Kolmogorov-Smirnov goodness-of-fit test. Finally, the confidence intervals of the estimated parameters corresponding to the candidate models are calculated, using the bootstrap confidence sets. In this thesis, earthquakes with Mw ≥ 6 along the DSFZ, with a width of about 20 km and inside 29.5° ≤ latitude ≤ 37° are considered as the dataset. The completeness of this dataset is calculated since 300 A.D. The DSFZ has been divided into three sub zones; the southern, the central and the northern sub zone respectively. The central and the northern sub zones have been investigated but not the southern sub zone, because of the lack of sufficient data. The results of the thesis for the central part of the DSFZ show that the earthquake occurrence rate does not significantly pursue a multimodal form. There is also no considerable difference between the time-dependent and time-independent models. Since the time-independent model is easier to interpret, the earthquake occurrence rate in this sub zone has been estimated under the exponential distribution assumption (Poisson process) and will be considered as time-independent with the amount of 9.72 * 10-3 events/year. The northern part of the DSFZ is a special case, where the last earthquake has occurred in 1872 (about 137 years ago). However, the mean recurrence time of Mw ≥ 6 events in this area is about 51 years. Moreover, about 96 percent of the observed earthquake inter-event times (the time between two successive earthquakes) in the dataset regarding to this sub zone are smaller than 137 years. Therefore, it is a zone with an overdue earthquake. The results for this sub zone verify that the earthquake occurrence rate is strongly time-dependent, especially shortly after an earthquake occurrence. A bimodal Weibull-Weibull model has been selected as the best fit for this sub zone. The earthquake occurrence rate, corresponding to the selected model, is a smooth function of time and reveals two clusters within the time after an earthquake occurrence. The first cluster begins right after an earthquake occurrence, lasts about 80 years, and is explicitly time-dependent. The occurrence rate, regarding to this cluster, is considerably lower right after an earthquake occurrence, increases strongly during the following ten years and reaches its maximum about 0.024 events/year, then decreases over the next 70 years to its minimum about 0.0145 events/year. The second cluster begins 80 years after an earthquake occurrence and lasts until the next earthquake occurs. The earthquake occurrence rate, corresponding to this cluster, increases extremely slowly, such as it can be considered as an almost constant rate about 0.015 events/year. The results are applied to calculate the time-dependent PSHA in the northern part of the DSFZ and neighbouring areas.

Повний текст джерелаThe main aim of this thesis is to analyse two types of general finite element approximations to the solution of a time-dependent variational inequality. The two types of approximations considered are the following: 1. Semi-discrete approximations, in which only the spatial domain is discretised by finite elements; 2. fully discrete approximations, in which the spatial domain is again discretised by finite elements and, in addition, the time domain is discretised and the time-derivatives appearing in the variational inequality are approximated by backward differences. Estimates of the error inherent in the above two types of approximations, in suitable Sobolev norms, are obtained; in particular, these estimates express the rate of convergence of successive finite element approximations to the solution of the variational inequality in terms of element size h and, where appropriate, in terms of the time step size k. In addition, the above analysis is preceded by related results concerning the existence and uniqueness of the solution to the variational inequality and is followed by an application in elastoplasticity theory.

Повний текст джерелаNeurons are excitable cells which communicate with each other via electrical signals. In general, these signals are processed by the Neurons in a nonlinear fashion, the exact mathematical description of which is still an open problem in neuroscience. In this thesis, the broad topic of nonlinear signal processing is approached from two directions. The first part of the thesis is devoted to the question how input signals modulate the neural response. The second part of the thesis is concerned with the nonlinear reconstruction of input signals from the neural output and with the estimation of the amount of the transmitted information. The results of this thesis demonstrate how existing linear theories can be extended to capture nonlinear contributions of the signal to the neural response or to incorporate nonlinear correlations into the estimation of the transmitted information. More importantly, however, our analysis demonstrates that these extensions do not merely provide small corrections to the existing linear theories but can account for qualitatively novel effects which are completely missed by the linear theories. These effects include, for example, the excitation of harmonic oscillations in the neural firing rate or the estimation of information for systems with a signal-dependent output variance.

Real-time scheduling for task sets has been studied, and the corresponding schedulability analysis has been developed. Real-time systems using rate monotonic (RM) fixed priority scheduling can be checked for schedulability either by sufficient but pessimistic schedulability conditions or by exact test. In this thesis, a series of period-dependent schedulability test methods for real-time tasks scheduled by the RM policy on uniprocessor systems are proposed. In the first portion, we find the efficient schedulability test methods for periodic tasks. Both exact schedulability test methods and sufficient but pessimistic schedulability test methods are investigated. Exact testing provides a more precise result but may not be performed in polynomial time. Audsley et al. proposed one of the earliest methods by iteratively deriving the response times of jobs. Other researchers have improved the exact test method by using different initial values for testing. In this thesis, we first improve the iterative formula used to calculate the response times of jobs. Then, we propose a new initial value for Audsley’s test method to improve the efficiency. We show that the new initial values can significantly improve the efficiency of exact testing. In addition, a better RM schedulability bound for performing the sufficient but pessimistic schedulability is also proposed. The period ratios are considered in the schedulability bound. When more period ratios are considered, the schedulability bound can be higher. In the second portion, we find the efficient schedulability test methods for multiframe tasks. We explore both exact schedulability test methods and sufficient but pessimistic schedulability test methods. For the exact schedulability test, the period-dependent initial value is used for the test and effectively reduce the number of iterations for testing. For the sufficient but pessimistic schedulability test, we use the information of the relative period ratios between tasks in a system to derive a new schedulability condition. By considering the smallest and the largest period values in a system, we can show that the RM schedulability bound can be improved significantly. This method also can be applied to other test methods studied earlier to improve the schedulability of real-time multiframe systems.

Most inventory models assume that the inventory can be stored indefinitely. However, in fact, if some inventories were stored for a long time, they will deteriorate, volatilize, or decay, so their value and quantity will also decrease. This type of inventory is therefore called “ Deteriorating Inventory “. If we did not consider deterioration, then we would have an incorrect cost-construction in the inventory model and a substantial lost would follow a wrong decision based on the model. Besides, most traditional inventory models considered the case where the demand rate is constant, but this assumption is not real. However, in the real situation, the demand rate is not only dependent of the product price but also inventory level. Furthermore, if backlogging time is too long, some customers will purchase with other companies. For the original company, it will result in opportunity cost due to lost sales. Therefore , the opportunity cost due to shortage, should be considered in our inventory model. On the other hand, during the past years, however, monetary situation of most countries has changed; this result in a sharp decline in the purchasing power of money. Therefore, the consideration on the effect of time-value of money is critical. Based on the above issues, we develop three inventory models in this thesis. In Chapter 2, we explore the inventory replenishment policy for deteriorating items with price-dependent demand over a fixed planning horizon, in which the backlogging quantity in the last period is made at time H. In Chapter 3, we also explore the inventory replenishment policy for deteriorating items with price-dependent demand over a fixed planning horizon, in which the shortages cannot occur in the last period. Final, in the Chapter 4, we present the inventory replenishment policy for deteriorating items with stock-dependent demand over a fixed planning horizon, in which the backlogging quantity in the last period is made at time H. The objective of these models in this thesis is to derive the optimal replenishment policy, in which the price, replenishment number and service level are common decision variables. For all models proposed in this thesis, we utilize the numerical examples to illustrate the effects of inventory systems associate with changing the values of parameters.

In the classical inventory models, it is generally assumed that the demand rate is constant. However, it has been observed that in some situations the demand may be influenced by the on-hand inventory; i.e. the demand rate may go up or down if the on-hand inventory level increases or decrease. In the real market, occurrence of shortages in inventory system is a natural phenomenon. Under certain situations, the amount of demand backlogged is variable and may depend on the amount of demand already backlogged; i.e. the customers will not wait for goods if already many customers are waiting. With today's high rate of inflation and a consequent sharp decline in the purchasing power of money, it is no longer wise to ignore the effects of inflation and the time-value of money in inventory system. In this paper, we establish three various inventory replenishment policies with shortages, where the demand rate is assumed to be linearly dependent on the instantaneous stock level. The effects of stock-dependent demand rate, deterioration, inflation and the time-value of money are used in conjunction with the economic order quantity model are the focus of discussion. We shall be concern with finding the optimal replenishment and shortage points and hence to determine the optimal service rate and number of replenishments. Numerical examples and sensitivity analysis are presented to illustrate the proposed models. Furthermore, we identify the best alternative among various models on minimizing total relevant costs over a finite time-horizon.
