the way memory hierarchy has evolved in recent decades has opened new challenges in the development of indexing structures in general and spatial access methods in particular. In this paper we propose an original approach to represent geographic data based on compact data structures used in other fields such as text or image compression. A wavelet tree-based structure allows us to represent minimum bounding rectangles solving geographic range queries in logarithmic time. A comparison with classical spatial indexes, such as the R-tree, shows that our structure can be considered as a fun, yet seriously competitive, alternative to these classical approaches.

this paper aims to investigate the capability of mixed-integer linear programming (MILP) method and genetic algorithm (GA) to solve binary problem (BP). A comparative study on the MILP method and GA with default and tuned setting to find out an optimal solution is presented. the mixed-integer programming library (MIPLIB 2010) is used to test and evaluate algorithms. the evaluation is shown in quality of the solution and the execution time of computation. the results show that GA is superior to MILP in execution time with inconsistent results. However, MILP is superior to GA in quality of the solution with more stable results.

Total Knee Replacement (TKR) is an increasingly common surgery worldwide. A significant contributor to TKR success is post-surgical rehabilitation. In this work, we present fun-Knee (TM), a novel sensor-equipped knee support complemented by mobile device-supported games, specifically designed for "gamified" TKR rehabilitation. Two inclinometers are used to measure the knee angle, which is used as the main input to the developed game. Human-Centered Design theory is applied throughout the game design to ensure a customized, dynamic gaming experience to maximize the pain distraction effect and to increase the exercise compliance and improve the rehabilitation outcome. Preliminary survey results collected from practicing physiotherapists show promising outcomes of the developed prototype, in terms of hardware and software characteristics, usability, clinical utility and overall effectiveness.

Vertex cover (VC) is one of the most fundamental graph-theoretical problems and has been widely used in wireless sensor networks (WSNs), particularly for the link monitoring problem. It is well known that a solution to the independent set problem (IS), which is another fundamental graph-theoretical problem, is complement of a VC. Self-stabilization is an important concept for designing fault tolerance systems. there have been many self-stabilizing VC and IS algorithms in the field. Even though a self-stabilizing IS algorithm can provide VC solutions, it does not give a theoretical guarantee on approximation ratio. In this work, we focus on practical fault tolerance performance of self-stabilizing IS algorithms in case of a vertex cover problem, particularly link monitoring in WSNs. We implement all existing self-stabilizing VC and IS algorithms and make simulations assuming a WSN in which nodes run synchronously. Results show that self-stabilizing IS algorithms in general are able to find better covers than VC algorithms, as they provide roughly 15% smaller solution sets. Furthermore, IS algorithmsthat run under distributed scheduler converges to a desired configuration in considerably less number of rounds than VC algorithms.

the seriation problem is an important problem in combinatorial optimization. the goal of seriation is to find a linear order for data objects to reveal structural information given a loss or a merit objective function as an objective function. For the seriation problem, finding an optimal solution using exact algorithms (e.g., branch-and-bound) to find the optimal solution is currently impractical for problems with more than 35 objects. In this paper, we develop a new heuristic procedure to maximize the gradient measure which is our selected merit objective function. the proposed heuristic incorporates search intensification and diversification into standard tabu search (TS) algorithm. From our experimental results, it shows that intensification and diversification tabu search (IDTS) outperforms the standard TS algorithms in terms of efficiency, effectiveness, and robustness.

this study evaluated the usability of the children's Urdu learning mobile Apps for Tablet-PCs. the pre-test questionnaire based on demographic information of the participants, post-test questionnaire using the fun Toolkit and the usability tasks were developed for collecting data from the children. the usability test was conducted by 232 participating children having age between 5 and 10 years of the primary schools. After filling the demographic questionnaire, the usability tasks were given to the children where time was recorded for each of the tasks. Afterwards, the post-test questionnaire was administered among the children in order to gather their opinion about the apps. the study result illustrated that the App3 was the best App in terms of efficiency and effectiveness. According to the Smileyometer results, the children reported more fun in using the App3. the Again-Again table results also show that the children wanted to use the App3 again and again. this study proposed the best Urdu learning mobile App from learning perspective for the children which is recommended to be complemented withthe existing traditional classroom learning in the schools of the country for enhancing their learning outcomes.
