rên thế giới ngày nay, những sách vở nói về các vấn đề huyền linh có rất nhiều, sau khi sưu tầm sự thật về những bậc làm cho tôi cảm thấy khích lệ tinh thần để trình bày kinh nghiệm riêng của tôi về những đấng Chân Sư của Phương Đông. Trong những chương sách này, tôi không có ý diễn tả một tín ngưỡng hay một tôn giáo nào. Tôi chỉ đưa ra...

Trong giáo trình Lịch Sử Thế Giới Cận Đại này, lịch sử thế giới cận đại được bắt đầu từ cuộc cách mạng tư sản Anh giữa thế kỉ 17, kết thúc bởi cuộc cách mạng XHCN tháng Mười Nga và chiến tranh thế giới lần thứ I đầu thế kỉ 20. Ngay trong thời kì cận đại cũng khó có được một sự phân định rõ rệt thống nhất chung cho cả...

Security issues in the Android cross-layer architecture
The security of Android has been recently challenged by the discovery of a number of vulnerabilities involving different layers of the Android stack. We argue that such vulnerabilities are largely related to the interplay among layers composing the Android stack. Thus, we also argue that such interplay has been underestimated from a security point-of-view and a systematic analysis of the Android interplay has not been carried out yet. To this...

Energy-Aware Task Partitioning on Heterogeneous Multiprocessor Platforms
Efficient task partitioning plays a crucial role in achieving high performance at multiprocessor plat forms. This paper addresses the problem of energy-aware static partitioning of periodic real-time tasks on heterogeneous multiprocessor platforms. A Particle Swarm Optimization variant based on Min-min technique for task partitioning is proposed. The proposed approach aims to minimize the overall energy consumption, meanwhile avoid deadline...

A Secure Dynamic Job Scheduling on Smart Grid using RSA Algorithm
Grid computing is a computation methodology using group of clusters connected over high-speed networks that involves coordinating and sharing computational power, data storage and network resources. Integrating a set of clusters of workstations into one large computing environment can improve the availability of computing power. The goal of scheduling is to achieve highest possible system throughput and to match the application need with the...

The Necessity for Hardware QoS Support for Server Consolidation and Cloud Computing
Chip multiprocessors (CMPs) are ubiquitous in most of today's computing fields. Although they provide noticeable benefits in terms of performance, cost and power efficiency, they also introduce some new issues. In this paper we analyze how the interference from Virtual Private Servers running in other cores is a significant component of performance unpredictability and can threaten the attainment of cloud computing. Even if virtualization is...

Magneto-optical trapping of diatomic molecules
The development of the magneto-optical trap revolutionized the fields of atomic and quantum physics by providing a simple method for the rapid production of ultracold, trapped atoms. A similar technique for producing a diverse set of dense, ultracold diatomic molecular species will likewise transform the study of strongly interacting quantum systems, precision measurement, and physical chemistry. We demonstrate one- and two-dimensional...

Photoproduction of η ′ mesons off nuclei and their properties in the nuclear medium
We study the photoproduction of $\eta^\prime$ mesons from nuclei near the threshold within the collision model based on the nuclear spectral function. The model takes properly into account both primary photon-nucleon and secondary pion-nucleon $\eta^\prime$ production processes as well as the effect of the nuclear $\eta^\prime$ mean-field potential on these processes. We find that the secondary pion-induced reaction channel ${\pi}N \to...

Electromagnetic form factors of the nucleon in effective field theory
We calculate the electromagnetic form factors of the nucleon to third chiral order in manifestly Lorentz-invariant effective field theory. The ρ and ω mesons as well as the ∆(1232) resonance are included as explicit dynamical degrees of freedom. To obtain a self-consistent theory with respect to constraints we consider the proper relations among the couplings of the effective Lagrangian. For the purpose of generating a systematic power...

A measurement of 74Ge(p,gamma)75As at low proton energies, inside the astrophysically relevant energy region, is important in several respects. The reaction is directly important as it is a bottleneck in the reaction flow which produces the lightest p nucleus 74Se. It is also an important addition to the data set required to test reaction-rate predictions and to allow an improvement in the global p+nucleus optical potential required in such...

Computability of the causal boundary by using isocausality
Computability of the causal boundary by using isocausalityar Recently, a new viewpoint on the classical c-boundary in Mathematical Relativity has been developed, the relations of this boundary with the conformal one and other classical boundaries have been analyzed, and its computation in some classes of spacetimes, as the standard stationary ones, has been carried out. In the present paper, we consider the notion of isocausality given by...

Metric Properties of the Fuzzy Sphere
The fuzzy sphere, as a quantum metric space, carries a sequence of metrics which we describe in detail. We show that the Bloch coherent states, with these spectral distances, form a sequence of metric spaces that converge to the round sphere in the high-spin limit. It is common practice in several fields to "approximate: a manifold with a finite or countable subset of its points. A typical example in particle physics is the study of quantum...
