This paper implements Simultaneous Localization and Mapping (SLAM) technique to construct a map of a given environment. A Real Time Appearance Based Mapping (RTAB-Map) approach was taken for accomplishing this task. Initially, a 2d occupancy grid and 3d octomap was created from a provided simulated environment. Next, a personal simulated environment was created for mapping as well. In this appearance based method, a process called Loop Closure is used to determine whether a robot has seen a location before or not. In this paper, it is seen that RTAB-Map is optimized for large scale and long term SLAM by using multiple strategies to allow for loop closure to be done in real time and the results depict that it can be an excellent solution for SLAM to develop robots that can map an environment in both 2d and 3d.

The aim of the experiment is to study elliptically polarized light using a Fresnel rhomb and to determine the ratio of semi major axis to the semi minor axis of the various elliptically polarised light forms for different angles of plane polarised incidence at the rhomb

The use of Customer Relationship Managers to foster customers’ loyalty has become one of the most common business strategies in the past years. However, CRM solutions do not fill the “abundance of happily ever-after relationships” that business needs, and each client's perception is different in the buying process. Therefore, the experience must be precise, in order to extend the loyalty period, of a customer as much as possible. One of the economic sectors in which CRM's have improved this experience is retailing, where the personalized attention to the customer is a key factor among others. However, brick and mortar experiences are not enough to be aware in how environmental changes could affect the industry trends in the long term. A base unified theoretical framework must be taken into consideration, in order to develop an adaptable model for constructing or implementing CRM’s into companies. Thanks to this approximation, the information is complemented and the final outcome will increment the quality in any Marketing/Sales initiative. The goal of this article is to explore the different factors grouped by three main domains within the impact of the service quality, from consumer’s perspective in both on-line and off-line retailing sector. Secondly, we plan to go a step forward and extract base guidelines about previous analysis for designing CRM’s solutions focused on the loyalty of the customers for an specific retailing sector and its product: Sports Running Shoes. Furthermore, we design and develop a structured survey and give it to a diverse group of users, with questions that evaluate the contrast an influence of service quality, customer satisfaction and customer loyalty in both on-line and off-line environments.

We will study some aspects of the damped driven pendulum. We will see that the trajectory of damped driven pendulum is unpredictable under certain ranges of parameters. Under some conditions, the trajectory behaves like random. A perturbation of initial condition will lead to different result. Several mathematical tools will be introduced in this study.

This research paper aims at exploiting efficient ways of implementing the N-Body problem. The N-Body problem, in the field of physics, predicts the movements and planets and their gravitational interactions. In this paper, the efficient execution of heavy computational work through usage of different cores in CPU and GPU is looked into; achieved by integrating the OpenMP parallelization API and the Nvidia CUDA into the code. The paper also aims at performance analysis of various algorithms used to solve the same problem. This research not only aids as an alternative to complex simulations but also for bigger data that requires work distribution and computationally expensive procedures.
