    This study investigated some aspects of infertility in British Highland Cattle on two farms in Scotland. In farm 1, the study involved 48 head of post-partum cows which were examined, monitored for fertility and recorded in a computer spread sheet using a commercial spreadsheet "Microsoft Excel". This investigation also involved the study of chromosomal defects and examination of reproductive tracts using rectal palpation, plasma progesterone concentrations and ultrasonography. A second herd of animals, on farm number 2 near Oban, Argyll, which had reproductive problems in growing heifers was also examined for other aspects of fertility. Examination of abattoir specimens of the reproductive tracts from culled unproductive animals was carried out. Chromosomal analysis was undertaken on both of these farms when the initial blood culture revealed the existence of Robertsonian translocation in farm 1. On the whole, the reproductive parameters in farm 1 showed a slight decline in fertility compared with accepted standards. The results implicated certain individual cows which had contributed to this reduction in fertility. This could be seen in the wide variations of the results obtained. Thus, in order to improve the fertility of the herd, it was necessary to identify these problem cows and consider culling them as culling due to infertility was almost negligible on the farm. The causes of infertility were complex as no simple cause was identified. This study could only rule out likely causes through the process of elimination and to concentrate on the potential areas that could be the contributing source of this infertility problem. Specific disease screening of the bulls was recommended, especially when natural mating was practiced. Further studies in this area could elucidate, and may help to identify, the cause of infertility. As there was no simple cause of the infertility in herd 1, various ways of improving the fertility through good management, nutrition and introduction of superior genetic materials by the use of AI or even ET is recommended. Thus, computerisation of the breeding records would enable fertility analysis to be carried out promptly and action lists produced to assist in the management decision. On farm 2, the majority (92%) of the uterine cultures of the reproductive tract from the abattoir specimens harboured no bacteria. About 67% of these tracts showed some form of gross morphological abnormality involving the tubular genitalia. However, histological sections of the endometrium revealed no obvious abnormalities. Detailed chromosomal investigation was carried out on 69 animals. This showed that 11.36% and 12% of cattle on farms 1 and 2 respectively were found to be heterozygous for a Robertsonian translocation, identified as involving numbers 1 and 29. Studies of the pedigrees of the last 5 generations of the positive cases were carried out to identify the source of inheritance. It is suggested that de novo production of the genetical aberration could have occurred some generations ago in the breed. It was found that the defect did not have any apparent affect on fertility in the present study. This was the first time that the 1/29 Robertsonian translocation has been found in this breed

    The purpose of the study is to identify the relationship between the variables of teacher's perception towards the usage of media materials in teaching mathematics in secondary schools in Perlis. This study also identifies the differences in teachers' perception based on gender. A total of 181 mathematics teacher is involved as the respondents. The data is collected through questionnaires and analyzed using SPSS version 12. The results of the study reveal that there is a positive significant relationship between the skill variables and facilities provided, skill and effectiveness of usage media materials, facilities provided and effectiveness of usage media materials and facilities provided and problems faced. The results also show a negative significant relationship between the skill variables and problems faced and effectiveness of usage media materials and problems faced. The results of the study also indicate that there is a significant difference in perception between male and female teachers towards the usage of media material in teaching mathematics. The male teachers' perception is higher than female teachers. Through the findings, it is clear that the usage of media materials is important in the teaching of mathematics. Nevertheless, a good planning need to be carried out prior before using the media materials and these materials must also be used appropriately and relevant to the subject matter. In this way, the teaching of mathematics in the secondary schools will be more effective and efficient

    Human heart contains a lot of informations that indicate the condition of its operation and health. The informations can be extracted using image, acoustic, electric and vibration signal. The problem with current technology is that it suffers badly with noise and other unwanted interference. To address this noise issue with the latest technology is echocardiography, a diagnostic tool for diagnosing on cardiac contractility and valvular disease. However, this device is quite costly and labour intensive which requires a specialist who is expert and enough experience in using this equipment. Furthermore, most of medical institutes unable to afford the cost of equipment facility. This study aimed to investigate the application of a non-invasive cardiac diagnostic approach using an accelerometer sensor array, coupled with a directional filtering approach to remove the unwanted noise. This work proposed the utilization of directional filtering method to remove noise using body vibration sensor by employing adaptive beamforming method without altering the signal information. Seismocardiography (SCG) was used to capture body vibration signals recorded via vibration sensor that collects information related to the heart pumping activities and later diagnosed the heart disease. The sensor array was used to collect SCG signal for 28 cycle data from normal and abnormal heart conditions of subjects in supine position. It was found that signal of heart disease information in SCG was overlapped with the noise signal. A directional denoising method which comprised of Delay and Sum (DAS) beamforming and Linearly Constrained Minimum Variance (LCMV) beamforming algorithm were applied, and the performance were compared. The result of signal to noise ratio (SNR) for DAS beamforming algorithm on normal subject was 7.11dB and abnormal subject was 4.13dB. For LCMV beamforming algorithm, normal subject was 10.85dB and abnormal subject is 7.04dB. Based on these results, it showed that the LCMV beamforming performed better than DAS as indicated in the SNR improvement by 30%. This SNR improvement represents the better accuracy of heart disease diagnosis

    This thesis proposes the development of an automated road traffic census prototype that is applicable to replace the current manual counts approach by applying image processing techniques. The developed system can be divided into three successive phases: the first phase is video frame preprocessing where a filtering technique using mask image is applied by defining the region for analysis in order to reduce computational complexity. The second phase is vehicle detection stage where the foreground moving vehicle is detected and identified using a combination of value and saturation (CVS) background subtraction technique. The third phase is vehicle counting and classification stage. In this phase, information of bounding box such as center point, width and height of the identified vehicles are used in implementing the counting and classification algorithm. Vehicles are counted when they passed through the defined lines and classified based on their dimension. The parameters used in the algorithms are discussed in detail in the report. The performance of the system is tested on four pre-recorded videos under different environment. The experiments' results show that the system has achieved an overall accuracy of 95% in detecting vehicles and accuracy of 82% in counting and classifying vehicles with a low amount of processing time

    Customer Relationship Management is gaining importance as a business strategy. It seeks to select, cultivate and manage the most profitable customer relationships with a view to increasing long-term profitability, through understanding customers\u27 needs. This requires organisations to understand the information requirements of CRM implementation. Most published work to date focuses on management information requirements. Little published research has examined front-end sales agents\u27 information needs and yet they are arguably the most important group of users, with direct interaction with customers. This paper seeks to close the knowledge gap by surveying a group of branch and call centre sales agents within a bank to identify their information needs
