Incentive-aware virtual machine scheduling in cloud computing

As cloud computing is a market-oriented utility, optimal virtual machine (VM) scheduling in cloud computing should take into account the incentives for both cloud users and the cloud provider. However, most of existing studies on VM scheduling only consider the incentive for one party, i.e., either the cloud users or the cloud provider. Very few related studies consider the...

A simpler and more realistic subjective decision theory

In his classic book “the Foundations of Statistics” Savage develops a formal system of rational decision making. It is based on (i) a set of possible states of the world, (ii) a set of consequences, (iii) a set of acts, which are functions from states to consequences, and (iv) a preference relation over the acts, which represents the preferences of an idealized rational agent...

Promoting cross-border knowledge transfer for new product development in MNCs: a process view

Cross-border knowledge transfer plays an important role in the competitive advantage of multinational corporations (MNCs). However, it can be quite challenging due to cultural differences and lack of trust between organizational units located in different countries. Prior studies have not explored the knowledge transfer process (and its key nodes) in new product development in...

Performance evaluation of the V2I fair access with a finite retry limit

This paper evaluates the performance of the vehicle-to-infrastructure (V2I) fair access with a finite retry limit through constructing an analytical model. Firstly, the process of the distributed coordination function (DCF) mechanism with a finite retry limit is described through developing a 2-D Markov chain; based on the Markov chain, the transmission probability with the...

Topographical factor-based shallow landslide hazard assessment: a case of Dayi area of Guizhou Province in China

Background Three groups of factors related to topography, geology and hydrology have influence on the triggering of shallow landslides in soil material. In this paper a single representative factor (T-factor) for the topography is proposed, which can be used to define threshold values for the possibility of shallow soil slides. This study was carried out in the Dayi area, Guizhou...

Bounded gaps between products of distinct primes

Let \(r \ge 2\) be an integer. We adapt the Maynard–Tao sieve to produce the asymptotically best-known bounded gaps between products of r distinct primes. Our result applies to positive-density subsets of the primes that satisfy certain equidistribution conditions. This improves on the work of Thorne and Sono.

Sliding Window Top-K Monitoring over Distributed Data Streams

Most of the traditional top-k algorithms are based on a single-server setting. They may be highly inefficient and/or cause huge communication overhead when applied to a distributed system environment. Therefore, the problem of top-k monitoring in distributed environments has been intensively investigated recently. This paper studies how to monitor the top-k data objects with the...

Numerical and experimental studies of stick–slip oscillations in drill-strings

A novel method for the detection of R-peaks in ECG based on K-Nearest Neighbors and Particle Swarm Optimization

Cardiovascular diseases are associated with high morbidity and mortality. However, it is still a challenge to diagnose them accurately and efficiently. Electrocardiogram (ECG), a bioelectrical signal of the heart, provides crucial information about the dynamical functions of the heart, playing an important role in cardiac diagnosis. As the QRS complex in ECG is associated with...

Proteomic analysis of early salt stress responsive proteins in alfalfa roots and shoots

Alfalfa (Medicago sativa) is the most extensively cultivated forage legume in the world, and salinity stress is the most problematic environmental factors limiting alfalfa production. To evaluate alfalfa tissue variations in response to salt stress, comparative physiological and proteomic analyses were made of salt responses in the roots and shoots of the alfalfa. A two...
