This paper proposes the design of a neural network controller based on a sample controller for controlling the trajectory-tracking motion of a differential drive mobile robot (DDMR). Firstly, the trajectory tracking model for DDMR is established based on position error. Next, a perceptron neural network is designed with three hidden layers to control the trajectory tracking of DDMR.

The data collected using purposive sampling and Slovin formula. The hypothesis of this research is tested by multiple linier regression. The research results showed that the variable site design, informative, security and communication have a partialy significant effect to the online shopping customer satisfaction, while the convenience of shopping variable is not significant. This understandable because each online store has different system and procedure that incovenience for consumers.

The aim of this research is to investigate the energy performance and water usage of aquatic centres. The objectives are to: 1. develop a guideline for the definition of aquatic centres in Victoria for the purpose of energy and water benchmarking; 2. benchmark the energy and water consumption of aquatic centres by analysing the data collected from existing facilities in Victoria; 3. To investigate operational and building design features that will improve the energy and water performance of a sample aquatic centre by using building performance simulation.

The current research project genotyped HAV RNA by using protocols and primer sets designed by HAVNET. It collected and genotyped previous HAV-positive samples in VIDRL sample bank, and the results were used to establish epidemiological and molecular database of the HAV strains. The database was used to investigate the relationship between the current diagnostic samples and the previous HAV infection cases. It was expected to identify the source of the hepatitis A infection.

Source and sink activity measured after anthesis in six poplar rice cultivars. The experiment was laid in randomized block design with six cultivars MTU-1001, MTU1010, MTU-7029, BPT-2231, BPT-3291 and BPT-5204 replicated four times. After anthesis, top three leaves separately, top three internodes collectively, panicle axis and grain of main culm were sampled at seven day interval and analysed for biochemical parameters that serve remobilization of nutrients. During the initial and later halves of the sampling, there was a shift in higher amylase activity from third to flag leaves.

The study was done based on primary and secondary data sources. A self-administered questionnaire was designed to collect relevant information from the selected 203 respondents. Among this 200 questionnaire were returned and analyzed. Multistage sampling method was used and employees are selected from each stratum with a systematic sampling technique. The collected data was analyzed by SPSS version 20 using descriptive statistics and multiple regressions.

The yearlings of Rohu (Labeo rohita) was fed with commercial pellated feed as T1(Control), feed incorporated with Lactobacillus sporogenes @ 4% as T2, Saccharomyces cerevisiae @ 4% as T3 and both Lactobacillus sporogenes @2% and Saccharomyces cerevisiae @ 2% as T4.The experiment was designed for 120 days in the cement tanks. Feeding was done with probiotics and without probiotics at alternate 15 days. Sampling was done at an interval of 15 days. The samples were analysed to determine the weight gain %, specific growth rate %, FCR, FER and TPC of probiotic microbes.

The performance of the simulation scheme has been compared with the commercial and laboratory samples in the world. Due to the deviation of all dosimeters with a flat energy response, in this paper, has been used an idea of one semi-conductor sensor to have the flat energy-response in the entire neutron energy range. Finally, by analyzing of the sensors data as arrays for the first time, we have reached a nearly flat and acceptable energy-response.

The analysis is carried out by the hypothesis testing and the event tree method. The probability of detection for diversion of 8 kg Pu is found to be less than 95% if a large size granule consisting of small size particles gets sampled for measurements. To increase the probability of detection more than 95%, first, a new Material Balance Area (MBA) structure consisting of more number of Key Measurement Points (KMPs) is designed.

This study explains the effects of repatriates on managers returning from foreign assignments. The first chapter provides the reader with an introduction to my chosen topic, the justification of undertaking the topic and my research objectives. The second chapter explains the research methodology, my questionnaire design and the problems I encountered when gathering information. The study goes on to explain the expatriation/repatriation process in detail. It begins with the selection criteria needed for expatriation and goes on to criticize it.

In this study the issue of staff retention is explored and the external and internal factors affecting staff working in a humanitarian context are analysed. The objective of the study is to identify the most appropriate approach NGOs can adopt to improve retention of Gen Y staff working in a humanitarian context. NGOs will then be in a position to design a HR strategy that takes into consideration the specific needs and expectations of Gen Y staff. This is turn will allow for a more sustainable humanitarian workforce and more effective humanitarian action.

This study will analyse the tax strategy that shaped the design of the suite of local property tax from the enactment of the legislation to the implementation of the tax and active collection programme by the Revenue Commissioners that lead to the high compliance rate. The fallout from this is discussed in addition to the advantages, disadvantages and obstacles to implementing such a framework. This paper also highlights the possible expansion of Revenues effective tax collection abilities to encompass future taxes and increased responsibilities.
