Recent Patents on Computer Science - Volume 8, Issue 2, 2015

With the increasing demand for social media, it is becoming increasingly important to ask our self: How far and how fast does information spread in social media? Researchers have recently examined a number of factors that affect and constrain the social contagion and information diffusion in online social networks, including: the Literacy Rate, GDP (PPP) and Gender. This paper is an analysis study for proportion of women usin Read More

There is still a gap of knowledge on the usage of recommender systems in Saudi universities and the wider issue of technological change in the universities of developing counties. Relatively, this lack of knowledge is an issue to universities seeking to meet students/instructors expectations and requirements by offering consistently high perceived service standards of e-learning services in a rapidly changing technological en Read More

An enhanced e-learning network based on integration between cloud environment and Web is probably suggested for the existing and upcoming e-learning tools that are considered as Software as a Service (SaaS). This paper examines three most recent patents that were awarded between February 2012 and May 2014 in the area of e-learning. In addition, we have proposed a new direction which is the possibility of integrati Read More

Educational institutions continue to look for opportunities to reduce the way they manage their resources. Cloud computing is an emerging computing paradigm that promises to provide opportunities to deliver a diversity of computing services in a way that has not been experienced before. In this paper, we will discuss the impact of cloud computing and recent patents on educational institutions and identify the key fa Read More

Knowing the hot topics in Social Networking Systems become essential for many applications such as marketing and social studies. Topic detection from Arabic posts or tweets using standard cluster labeling techniques such as the most frequent terms or the most predictive terms in the cluster lack the accuracy to catch the implicit semantic relations between terms. In this paper, in this approach we automatically cluster the Ar Read More

Emerging global environment of knowledge creation and its dissemination has complicated the challenges in the teaching learning. Wide spectrum use of technology driven teaching aids supplement the curricula with its applicative relevance in the practical life. Accompanying such a phenomena, digital and knowledge divide occurs due to lack of access and equity in terms of technology applications. The present pape Read More

In this paper, we present a solution for translating an existing relational database (RDB) schema with recent patents into relatively newer database (i.e., object-oriented and object-relational database) schemas, based on available standards. The solution is more beneficial compared to the existing approaches as it generates two different and equivalent target schemas based on the user choice. The main aim of the propose Read More

With the development of new technologies of information and communication, more and more data sources are available. The diversity, distribution and heterogeneity of these sources make their access a real issue. Data integration systems allow a unified and transparent access to heterogeneous data sources giving the illusion to user that he is accessing only one source. A query over the global schema of a data int Read More

Minimizing the risk/hazards in industrial plants and their surroundings has become a growing research field. Aspects such as continued industrial growth, the development of new technologies, climate changes, terrorists’ actions and society having greater access to information are just some of the factors that require a more structured study of risk. Gathering information about threats, the vulnerability of critical assets, the lik Read More

In allusion to the complementary of ant colony optimization (ACO) algorithm and genetic algorithm (GA), this paper proposes a novel hybrid ant colony genetic (NHACG) algorithm with recent patents based on integrating multi-population strategy and collaborative strategy. The solutions of the ACO algorithm is regarded as the initial population of the GA, and the ACO algorithm and GA are dynamically applied according to th Read More

This article deals with a new CAD system of railways routing. The route of railway as 3D curve is traditionally presented by two flat curves: plan and longitudinal profile. The plan of route is its projection on horizontal plane XOY and its longitudinal profile is dependent Z(s), where s - is the length of plan from initial point. The software of the new system allows us to receive the optimal project line of the longitudinal profile for each va Read More
