Recent Patents on Computer Science - Volume 10, Issue 3, 2017

Background: Since the patient-related data stored in the MCPS (Medical Cyber-Physical System) play a critical role in medical diagnosis and treatment, it is essential to ensure the security of these data. Failure to obtain authentic and correct medical data will possibly prevent a patient from being treated effectively, or even lead to wrong treatments, also described in various patents. Moreover, public may not accept M Read More

Background: The number of pedagogic web page created on the web, which corresponds to number of courses and exercises available on the web, exceeds the number of published books each year. These web documents are often too long to be easy to read, especially when important information is dispersed in various parts and often definite in a more or less formal way. Therefore, they must be described with machin Read More

Background: As one of the most popular racket sports in the world, tennis usually takes a considerable amount of repetitive training that uses a great number of tennis balls. After the training, collecting the tennis balls is an annoying, time consuming, and labor taking task. To cope with such problem, a great number of tennis ball collectors such as the stroller-based, basket-based, and wheeler-based collectors were proposed, Read More

Background: In the modern age when electric power is one of the major energies, electrical equipment and power transformer are indispensable. Power transformer is an important electric transmission and transformation equipment in electrical power system. The failure of power transformer may induce long-term power supply interruption and large economic loss. Therefore, the diagnosis and repair of broken-do Read More

Background: Recently, sparse representation has been significantly used in various image inverse problems, such as image deblurring, super resolution and compressive sensing, and has shown promising results. The key issue of sparse representation is how to find a reasonable dictionary, by which the image can present more sparsity, as described in various patents. Method: In this paper, we address the image restoration Read More

Background: Over the past few years, researchers have devoted efforts to enhance the robustness and randomness of the original DES cipher. These enhancements focused on improving multiple perspectives of the algorithm to deliver robust DES variants against typical attacks. Method: Recent publications and patent databases have been reviewed to investigate the potential enhancements in DES cipher algorithm. The e Read More

Background: Time synchronization between the sensor nodes to reduce average end to end delay with the increase in number of sensor nodes in a network for critical and real time data monitoring can be achieved by precisely predicting their wakeup/sleep timings and are of prime importance as described in recent patents. The idea evolves as a reduction in duty cycle and precise time scheduling of active/sleep cycles of the se Read More

Background: Energy-Efficiency is an important issue in Wireless Sensor Networks (WSNs) since sensors are battery powered and are deployed in unattended environments. Long distance transmission is very expensive in WSNs since power consumption is proportional to dα for transmitting over distance d, where α is path loss exponent in the interval [2:6]. Thus, there is a necessary requirement of relay nodes in the network Read More
