## Extract of sampleComparison of Two Sets of Data

The lab report "Comparison of Two Sets of Data" overviews two datasets of gross motor vehicle domestic weights from the year 2002 and from the year 2004. This report applied information from a secondary source for its investigation. The collected data was then subjected to statistical analysis using excel from which cumulative were developed. Further, histograms were developed to facilitate analysis of the two sets of data.
Gross vehicle domestic weight refers to the maximum weight of a vehicle based on the manufacturer’s specification. It normally indicates the combined weights of all elements of a vehicle such as a frame, body, engine, devices, luggage, and passengers. This information is contained in vehicles’ registration documents.
Statistical applications that offer ground for comparing and contrasting records of motor vehicle weights over periods can be used to investigate the existence of a change in a trend of gross weights. The combination of statistics from the two periods of time allows for easier analysis into identifying similarities and differences between the two sets of data. A review of the combined frequency distribution table, for example, identifies a comparative trend in the weights of the vehicles between the intervals less than 20 kipps up to 69.9 kipps. Though the paired frequencies within this range vary across the two years, the differences are significantly small, falling within a one percent disparity. A difference is observed beyond 70 kipps frequencies reported in the year 2004. ...

## Summary

This lab report presents a comparison of a set of data of gross motor vehicle domestic weights from the year 2002 and another set of weights from the year 2004 with the aim of comparing and contrasting the weights as were recorded during the two periods…

The flow through the pipe could either be laminar or turbulent and so the experiment will be directed to distinguishing the kind of flow. Flow should be started through the pipe being investigated. The pipe must have manometers installed on both ends of the region being investigated. The diameter of the pipe must be measured beforehand. The discharged fluid should be collected in an appropriate container that can aid volume measurement. A stop watch should be used to monitor the total time required for a certain volume to flow. Starting with an empty container, the fluid should be allowed to...

Surveying and mapping
Designing an effective and efficient survey network is one of the essential aspects in the implement of field surveys. In contrast, the design of a survey network is a complicated and sophisticated task because a survey network needs to meet or exceed specified criteria for precision, reliability, sensitivity, and cost. Other pivotal factors must be taken into account in a feasible design, such as geological criteria, suitability for equipment measurement, long term safety, field time and access costs (Talaya, et al., 1999). Therefore, it is vital to implement the techniques and instruments of...

Compare and Contrast Three Ethical Theories
The benefit of this ethical theory is that the utilitarian can compare and contrast similar predicted solutions and with his knowledge use a point system to determine which of the choices has more benefit to a majority of people. We always, or, rather, mostly focus on actions but we can have a change and focus on consequences. When we focus on consequences we wind up with consequentialism and utilitarianism is one type of consequentialism and the founding father was Jeremy Bentham. (Lafollette, 28)

condition monitoring, fault diagnosis, fault classification or fiding fault for machenary
In recent years, there has been a growing trend to introduce more intelligent methods in order to deal with condition monitoring and fault classification for machines (Mills, 2010). The realm of artificial intelligence and its application may be infant as yet but still involves the application of various methods and techniques for achieving desired ends. The current research will look into various artificial intelligence methods that have been applied to the condition monitoring and fault diagnosis for a reciprocating air compressor based on emerging and already developed methods and...

An Analysis of six Infrastructure projects that take place in two countries.
Differences in organizational cultures between companies or disparities in professional cultures between consultants, contractors and clients may exist. This dissertation aims to address the impact of political and cultural differences in project management of cross national projects. Apart from identifying the political and cultural differences that affect project management, case studies of six infrastructure construction projects in two countries have been conducted. The research suggests that differences in professional cultures, politics and institutions affect the successful management...

Fault Detection and Diagnosis using Principal Component Analysis of Vibration Data from a Reciprocating Compressor
PCA has been employed with genetic algorithms (GA) in order to reduce data dimensionality for use in fault diagnosis of induction motors. PCA was employed to remove relative features, after which GA was employed to select the irrelative features and to optimise the ANN (Yang, Han and Yin, 2006). Fault detection and diagnosis of plant subsystems have also been attempted using PCA. Normal plant operation decomposed through PCA was compared to faulty operation data through PCA decomposition to create thresholds for taking corrective actions. Real time monitoring of plant operation data was...
