Recent Patents on Computer Science - Volume 9, Issue 3, 2016

Background: Graph labeling problems have interesting applications in coding theory, communication networks, optimal circuits’ layouts and graph decomposition problems, as described in various patents. Consider a graph G = (V,E), with |V| = p and |E| = q.If f:V → {0,1,2,.....p} is a bijective mapping and if f+ : E → {1,2,... .q} be defined by f+ (uv) = |f(u) - f(v)|, for u, v ε V, and if f+ is bijective, then the induced map f+ gives a Read More

Background: Breast cancer is diagnosed as the most leading and dangerous cancer in women all over the world. Recent patents have shown that breast cancer is the second leading cause of death worldwide, among other cancers. This paper presents a development of breast cancer diagnosis system in digital mammograms using multiresolution technique. Methods: The proposed method uses the Ripplet Transform (R Read More

Background: An invention with societal acknowledgment has an incredible outcome on the comfort and effectively of a regular life. Shopping at enormous shopping centers is almost a routine in the urban communities. We see a huge rush in these shopping centers on vacations and weekends. Individuals buy diverse things and place the items in the cart. After one completes the shopping, customers are supposed to Read More

Background: Recognizing human faces across image processing is a difficult task mainly when it comes to age variation and occluded images. Aging causes a lot of variation in the human face and occlusion makes it difficult for us to recognize image of a person. Human faces undergo changes due to aging. These changes are affected by different factors and are subject to different age groups. In the early ages, like the Read More

Background: Since multiplication dominates the execution time of most DSP algorithms, there is a need of high speed, area efficient and power efficient multiplier. Also, many patents emphasize on the fact that multiplication time is still the dominant factor in determining the instruction cycle time of a DSP chip. Hence, there is a need for high speed- low power multipliers. This can be achieved by using the concept of Vedic Mat Read More

Background: Energy consumption is a major issue in Cloud Computing environments. Its efficient use can benefit in many ways such as cost saving, efficient utilization of resources and also saving the environment, as energy consumption, cost and time are important and decision making factors for both user as well as cloud service providers. QoS conscious scheduling of jobs along with energy awareness is very important, especi Read More

Background: It is very difficult for a physically handicapped people to lead their life as they are completely dependent on others for their needs. So it is essential to provide aid for the physically handicapped people to lead their life normally. Aim of our paper is to provide an assistant to physically disabled. Methods: Existing systems and patents to aid physically disabled is studied and latest trends are studied and proposed system i Read More

Background: In most of the applications we expect that security cameras or surveillance camera systems should work on an around the clock basis, as also described in various patents. Normal cameras which produce images in visible spectrum are not effective with the absence of natural light. Even though some solutions are there for such problems like morning time natural illumination and night time artificial illumination arran Read More

Background: Wireless sensors networks (WSNs) are now widely utilized for detection events, especially combined with data fusion technology that applies a new opportunity in this realm. The aims of this paper is to introduce readers to the existing multi-sensors fusion models and common algorithms, to conduct an illustration of indexing events approaches in multimedia sensors data, and provides an extensive analysis on e Read More

Background: According to nodes’ participating style, routing protocols can be classified into three categories, namely, direct communication, flat and clustering protocols. In direct communication protocols, a sensor node sends data directly to the sink. Under this protocol, if the diameter of the network is large, the power of sensor nodes will be drained very quickly. Furthermore, as the number of sensor nodes increases, colli Read More

Background: Energy consumption is one of the most critical issues that is considered in designing and improving routing protocols in wireless sensor networks; since the sensor nodes are equipped with limited amount of energy, and recharging these nodes is almost impossible, reducing energy consumption and raising the lifetime of wireless sensor networks has gained increasing attention from researchers. Methods: In this pap Read More
