If you conduct a scientific experiment or undertake a piece of research, you’ll usually need to write up a corresponding project or lab report, to summarize the objective of your task, the methods you followed, the results you obtained, and the conclusions you drew from your work. Here we provide a sample of great templates for producing such reports, which include layout guidelines to help guide you through the process.

Single phase, uncontrolled rectification (conversion)
An experiment investigating full wave rectification, for the purposes of producing a steady DC output. This is implemented using every half-cycle input from the supply voltage instead of every other half, this is known as a full wave rectifier.

Vision based gesture recognition with Kinect sensor
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.

Determining the Ratio of Specific Heats of\\ Gases using Adiabatic Oscillations
The ratios of specific heats, γ = (CP/CV), for three gases (air, argon and carbon dioxide) were calculated by measuring the oscillations of different masses in various apparatus. The experiments followed Rüchardt's and Rinkel's methods; a 100ml glass gas syringe was additionally used to extend the investigation as well as a technique to elimination of friction. The approaches and results were compared; the most accurate method (Rüchardt's method alongside compensation for friction) yielded:
Air, γ = 1.358 ± 0.0038
Argon, γ = 1.6597 ± 0.0009
Carbon dioxide, γ = 1.2996 ± 0.0087
These differ from the literature value by 3.0%, 0.6% and 1.5% respectively. The reasons for these apparent discrepancies are discussed.
Advanced Characterization of a-Si:H by SSPG, SSPC and MPC techniques Report
The objective is to study the effect of different experimental parameters on the reconstruction of the density of states (DoS) and to verify the viability of the 1D/2D simulation model developed at GeePs. Beside the calculation of the DoS through the modulated photo-current method (MPC), the ambipolar minority carrier diffusion length is measured through steady state photocarrier grating (SSPG) and the majority carrier lifetime / mobility product is measured through steady state photo-conductivity (SSPC). The measurements were observed to be in agreement with the theoretical simulations, but further experiments are needed to accurately conclude the need of a 2D simulation for the MPC experiment.

College Physics Lab Report
Motivation: The Neurosky Mindwave device allows monitoring the electrical signals generated by the brains neural activities. The easy access of this devices opens a new area of researching fields not only in the gamification and disable people but also to understand the cognitive behavior of human beings. The purpose of this study is to investigate the consistency and effectiveness level of a non-invasive consumer product BCI. We investigate the output of the headset data both in quality and quantity of that gathered data and determine how it could be used for human involved research settings. A sample of two participants in terms of an interview and an interviewer interchanging questionnaires. The cognitive tasks and EEG output signals captured by the participants both attentive and meditation values.
Results: The data we collected produces mixed results. The meditation or relaxing level provide a consisting output while the attention level need more to explore due to the nature of every individuals and also the surrounds such as noise, mode distraction levels etc.

Optimizing The Linux Scheduler For Performance.
The CPU scheduling is the basis of multi-programming operating systems. By switching the
CPU among processes, the operating system can make the computer more productive. The
scheduler controls the way processes are managed in the operating system.
Linux supports preemptive multitasking, this means that the process scheduler decides which process
runs and when.
Balance performance across different computer configurations is one challenge in modern operating
systems.Linux has two separate process-scheduling algorithms.
If a Linux system performs similar tasks in a regular manner, it could be useful to implement
optimizations to the Linux scheduler to optimize the performance of those tasks.
In this project, we analyze and evaluate the impact of changing the kernel values on the performance
of the calculation of 8,765,4321 digits of pi using the Leibniz formula measuring the time that the
system takes to perform the calculation.
