We consider a cloud service based on spot instances and explore bidding and pricing strategies aimed at optimizing users' utility and provider's revenue, respectively. Our focus is on jobs that are heterogeneous in both valuation and sensitivity to execution delay. Of particular interest is the impact of correlation in these two dimensions. We characterize optimal bidding and pricing strategies under...
Compressive sensing (CS) is a viable source of an innovative 5G system, what's more, it's an effective technology to deal with the data redundancy problem of massive machine-to-machine communication (MMC), since it enables the recovery of sparse and approximately sparse signals with significantly fewer samples than demanded by Nyquist-Shannon sampling theory. Interference in signal will lead a series...
Geometry-based stochastic model (GBSM) of multiple input multiple output (MIMO) channel describes the channel impulse response (CIR) in the sense of rays and clusters, which obey the empirical distributions. Thus, the correlation between MIMO sub-channels is not explicitly defined, which makes it difficult for GBSM to predict channel capacity accurately. Facing the increased antenna number of massive...
This study proposes a framework of Design-by-Analogy (DbA) based on Structure Mapping Theory (SMT). A workshop is held to apply the framework to transforming the observation on DbA in daily life into creative designs. Results show that the participants' transformations prefer relational mapping to mere element mapping. The creativity in ideation is higher than that in observation; meaning the better...
To resolve the problem of ambiguity caused by the folding used widely in direct acquisition (DA) of the precision code (P code) in the global positioning system (GPS), a two-step DA scheme is proposed based on the zero-padding and local P code modification. The coarse acquisition is achieved in the first step based on the folding, which allows us to maintain the advantage of the folding, and the zero...
This study was conducted to identify the relationship among some intrapersonal factors such as professional competency, interdisplinary ability, social skills capability, and team cohesion. The validated questionnaire was delivered to 296 students in the design programs of universities as research samples. Consequently, the SPSS 18.0 and AMOS statistic software were used to analyze the collected data...
Empirical studies in software engineering frequently rely on correlation data in an effort to demonstrate that a process or tool affects an important or meaningful outcome, with the ultimate goal of improving software engineering practice. But all students of statistics know that "correlation does not imply causation," and so causal conclusions (using traditional methods) from observational...
The reliability of electronic products depends on their ability to dissipate the heat generated by various components. Application of an array of parallel plates such as a heat sink is a common example of using parallel plates in electronics cooling. The most common practice in dissipation of the heat generated by electronics is by means of natural convection. Others have investigated the optimum...
This paper presents an experimental study on the legibility of Chinese characters printed on one-way vision film. In the study, Chinese characters of different font sizes were viewed from different distances by research subjects with normal eyesight in order to measure the lowest legibility value. The data generated as such failed to pass homogeneity of variance test. As homogeneity of variance is...
In recent years, fast development of video editing software has made video forgery applicable. One of the most frequently encountered forgery types in video forensics is the frame duplication forgery. Researches have proposed methods to deal with this type of forgery. The two main drawbacks of this methods reported in the literature are execution time and low detection accuracy. In this work a new...
Two-phase jet impingement is a compact cooling approach that provides high-heat-flux dissipation at manageable pressure drop. The heat transfer behavior of an impinging jet array is dependent on a set of geometrical parameters, operating conditions, and fluid properties. In the present study, a semi-empirical approach is developed to predict heat transfer from arrays of jets of liquid that undergoes...
In this article making an attempt to interpret the words and lyrics of poem and song as the cultural element extraction source, through the deep understanding and unearth of the content, to establish a new approach on cultural creative design. In the case of Taiwan's well-known lyricist and writer, Mr. Vincent Fang (Fang Wen Shan) and mandopop (Mandarin popular music) singer Jay Chou's (Chou JieLun)...
A well-done package enables a product to stand out from competitive brand packages and its form design is capable of creating the initial impression which generates associations regarding product images or consumers' responses to a product. This phenomenon is conspicuous in the packages of bottled products, such as perfume, beverage, shower gel and shampoo, bottled cosmetic and so forth. To create...
In this paper, we address the problem of visual tracking by proposing a novel feature learning technique. Recently, correlation filter based methods have dominated the visual tracking community due to various reasons such as efficient dense matching in frequency domain and simple update strategy. Nevertheless, the studies of correlation filters utilize handcrafted or pre-trained deep features of classification...
Because of the exponential development of advanced information, the information distribution center size gets increments. From this crude information, recognizing the breast cancer growth plays a testing errand in bunches the proper component. This is satisfied with semi-regulated machine learning calculation and closeness measure. We have taken here the genuine specimens of cancer malignancy with...
This informational collection is utilized to anticipate the odds of an event of heart assault for a patient. In the season of cutting edge smartphones contributing 12 attributes is not feasible. We play out the product metric examination on the given informational collection. In view of the investigation of information we try to bring the total number of attributes into a small figure and in the end,...
This paper determines methods to develop a novel technique for predicting a nation in view of the Olympic awards owned by 2012. It is the combination of three methods are Pearson correlation coefficient, Spearman correlation coefficient and along with linear regression. The main idea of the paper is to compare the value of Spearman and Pearson correlation coefficient as there in the same set of data...
Based on the spearman similarity measure the attribute are analyzed using boxplot. In this real-time data of Australian energy market operator, data dashboard in national electricity market provides the average price history of few years. Here, analyze the temperature with electricity usage based on year. We try to implement the amount of electricity usage is depend on the temperature of the country...
Spearman's rank relationship coefficient is a nonparametric (dispersion free) rank measurement. Spearman's coefficient is not a measure of the direct relationship between two factors, as a few ”analysts” proclaim. Pearson's relationship coefficient is the covariance of the two factors separated by the result of their standard deviations. The possibility of the paper is to look at the estimations of...
With the advancement of the product improvement, the size of the product is progressively developing to the degree that we can't hand it effortlessly. A few measurements are proposed to measure the multifaceted nature of programming in last a couple of years. This article goes for an extensive overview of the metric of programming multifaceted nature [2]. Hence we have used two developing method of...
