Gesture recognition and its implementation that support Human Computer systems are becoming very popular mode of interaction now a days. It allows to interfacing the man machine commutative information flow naturally. Vision based gesture recognition has the potential that can provide intuitive and effective interaction between man and machine. However there are not adequate tools and techniques that support for developing, detecting or executing these tasks. In this paper we will implement a prototype that facilitates recording data during building some action based activities captured by the Kinect sensor. We analyze those recorded clips and visualize the user interactions by recognition the gestures objects based on depth, IR and skeletal data. Kinect tools include an analysis feature, a time-line-based approach that manually or automatically can mark the recording sequences of clips. We will implement both discrete and continuous gestures by using AdaBoast machine learning approach to detect hands activities. Our result suggest that the learning mechanism can achieve more than 98% of confidence level of given gestures.

The complete business report acts as proposal ending with a decision on whether the idea is viable or not. A positive conclusion will lead to a suggestion of further investigation within this field. Present day wind turbine faces plenty of maintenances, issues and blade failures, all these problems together are difficult to handle and thereby very costly. That is why this report aims to come up with an idea solution to detect manufacturing errors and faults before installing the wind turbine blades. This business report aims to investigate whether a Manufacturing Scanner has the ability to detect errors and faults in new wind turbine blades. In addition the business report examines if the idea based on a Net Present Value calculation along with a budget is economically beneficial. The business report includes a technical description of an x-ray scanner, materials in wind turbine blades and software detection of anomalies. A business plan is conducted to determine whether the Manufacturing Scanner is a viable business opportunity. The business plan consists of a market analysis, which includes a supply chain, positioning, pricing and customer segments, and furthermore a budget, including a Net Present Value and business case. Based on the investigated areas and the final conclusion, the idea seems viable. The scanner is possible to produce at a reasonable price, the project is economically beneficial and there is a present market potential.

his project is part of the FlowNet initiative. FlowNet aims at providing Internet freedom and free flow information through socially informed, censor resistant online social networks. My contribution for FLowNet is in devel- oping an Android application, SecurePost. The requirement for SecurePost is two-fold. First, the system should facilitate secure, anonymous, group communication within a closed group of trusted members. Second, the general public on the Internet viewing this content, should be able to verify that the content was generated only by the said closed group of trusted members. The system consists of an Android client application, a proxy server and a browser-plugin. The OSNs supported by this system are Twitter and Facebook.

The aim of this laboratory work is to design a strut/bracket assembly for aircrafts. Experiments are carried out to determine mechanical properties of certain materials.The material chosen is Mild Steel. Given the possible condition experienced by the material and the safety factor, the dimensions for the designs of the strut/bracket assembly for aircrafts are obtained to avoid failure by yield or fracture. The diameter of the pin, d ,which is subjected to shear stress should be larger than 14.56mm. The diameter of the rod, D, should be larger than 12.74mm. The thickness of the rod would be 10mm.

Through the modification of the kernel on a Ubuntu system, we managed to solve the n-Queens problem after changing the default time-slice, swappiness, latency and wakeup-granularity to different values and testing the problem.

Optimization is a crucial step in the development context of algorithms, where depending on the purpose, different levels of optimization can be applied. Thus, the Network Dijkstra algorithm has been choosen in order to perform the compilation and execution with some levels of optimization from the GCC, measuring its execution time, number of cycles and instructions. In the present work, it is also discussed how the front-end and middle-end analyzes are performed in GCC.
