Point clouds have emerged as a promising solution for immersive representation of 3D contents. In this paper an interactive subjective quality assessment for point clouds is proposed. Quality assessment of geometry information in point clouds subject to realistic types of degradations is performed and correlation between state-of-the-art objective metrics and ground truth subjective scores is investigated...
The penetration of smartphones and advancement of the location-based services have jointly contributed to the popularity of location-based social networking platforms such as Foursquare and Yelp. Business owners are important stakeholders of such location-based social network (LBSN) platforms, for whom setting up new businesses at the right location has immense importance in making a business popular...
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...
The paper presents the researches to determine the effectiveness of different criteria to estimate the complex biology objects clustering quality. The gene expression sequences of cancer patients were used as experimental data. The degree of the studied objects similarity was estimated by the comparison of the gene expression sequences profile using different metrics to estimate the objects proximity...
Nowadays recommender systems are developed to provide information for users to choose the best things that they want. Recently different collaborative filtering techniques have been successfully employed to provide precise recommendations. However, sparsity problem is still considered as an important remained challenges. Existing CF based recommendation methods generally focus on positive similarities...
Recently, with the surge of students pursuing graduate studies after completing their bachelors, there is a lack of open source resources which could point out universities and programs, based on an individual's profile. In this paper, we present our novel approach of predicting universities for graduate studies based on one's whole profile. A model is built which is able to predict the list of top-‘n’...
This paper investigates two metrics related to the traceability relationships that exist between requirements and architectural design. In particular, we look into cross-cutting requirements, i.e., requirements that are implemented by several components, and, conversely, into overloaded components, i.e., components that implement several requirements. The intuition is that intricate dependencies between...
Enterprises and researchers often have datasets that can be represented as graphs (e.g. social networks). The owner of a large graph may want to scale it down to a similar but smaller version, e.g. for application development. On the other hand, the owner of a small graph may want to scale it up to a similar but larger version, e.g. to test system scalability. GSCALER is a recently developed tool...
Emulation of a realistic environment is modeled in an anechoic chamber to measure the performance of a Base Station Massive MIMO Array antenna using a Spatial Channel Model. The first bounce path establishes the angles of departure and angle spreads observed by the MM array and each is produced by probes placed in the chamber. A channel emulator is utilized to model the full connection between the...
In the last two decades, the increase in the amount of information available online have resulted in an information overload problem making it very complex for users to get the useful information they require within time. A recommender system helps customer to make useful decisions about products they wants to purchase thus providing better customer satisfaction which is vital in online environments...
Predicting change-prone object-oriented software using source code metrics is an area that has attracted several researchers attention. However, predicting change-prone web services in terms of changes in the WSDL (Web Service Description Language) Interface using source code metrics implementing the services is a relatively unexplored area. We conduct a case-study on change proneness prediction on...
In recent years, social media such as Twitter have encountered a significant growth because of the ceaseless increase in the volume of contents and the number of users. The level of influence among social media users is significantly different from one user to the other; and as such, it has become more vital to find the most influential users on social media. There are lots of mysteries about behaviours...
In this paper, we evaluate the usefulness of metrics that assess susceptibility to cascading blackouts. The metrics are computed using a matrix of Line Outage Distribution Factors (LODF, or DFAX matrix). The metrics are compared for several base cases with different load levels of the Western Interconnection (WI). A case corresponding to the September 8, 2011 pre-blackout state is used to compute...
This paper presents an online algorithm for mobile user speed estimation in 3GPP Long Term Evolution (LTE)/LTE-Advanced (LTE-A) networks. The proposed method leverages on uplink (UL) sounding reference signal (SRS) power measurements performed at the base station, also known as eNodeB (eNB), and remains effective even under large sampling period. Extensive performance evaluation of the proposed algorithm...
With the emergence of Augmented Reality (AR) services in a broad range of application scenarios, the interplay of (compressed) content as delivered and quality as experienced by the user becomes increasingly important. While significant research efforts have uncovered interplays for traditional (opaque) media consumption scenarios, applications in augmented vision scenarios pose significant challenges...
Tremendous interest prevails in developing a convenient and effective wearable medical device for evaluating sleep at home. The current study presents the clinical validation of VitalPatch®, a wireless adhesive patch sensor for screening of sleep architecture compared to the gold standard polysomnograph (PSG). A group of 45 volunteers were attached to a standard 22-channel PSG and a VitalPatch sensor...
Given the high drop-out rates of students from colleges in USA, including STEM fields, there is a national imperative to address this issue with all possible means. Universities are pushed towards providing students with personalized attention and timely academic feedback. At the same time, intrinsic student motivation also plays an enormous role in success. It is important for educators to present...
In order to better understand what structural and functional brain components changes are associated with schizophrenia, various investigations have been conducted. Functional Network Connectivity (FNC) generally interpreted as an indirect measure of brain activity, measures the functional component, and Structural Based Morphometry (SBM), an indirect measure of concentration of Gray Matter (GM),...
In this note, we extend the notion of Ollivier-Ricci curvature on weighted graphs with all positive weights to the case in which the weights may also be negative. This is done by employing the Hahn-Jordan decomposition of signed measures, allowing us to extend the Earth Mover's Distance to an extended class of measures. The resulting curvature will be utilized to study the robustness properties of...
Because of the volatility of memory, nodes in in-memory storage system crashing down would lead to data lost. One solution to this problem is backing data up. However, if we backup data to a node which is about to fail down, the data should be recopied again. That would lead to a large amount of backup data, and in turn reduce the system reliability. We first establish a correlated failure model with...
