Paper Title :: Factors Influencing Milk Production Project Among Small Scale Dairy Farmers in Bomet East Sub County, Bomet County, Kenya
Author Name :: Michael Kipkirui Cheruiyot || Dr. Moses M. M. Otieno
Country :: Kenya
Page Number :: 01-23
The research was based on the factors influencing milk production project among small scale dairy farmers in Bomet East Sub County, Bomet County, Kenya. The study was guided these objective : to determine the extent to which demographic characteristics of small scale dairy farmers influent milk production project in Bomet East Sub- count, to analyze how cattle breeds variability affects milk production project in Bomet East Sub county , to examine how marketing factors influence milk production project among Small scale dairy farmers BometEast Sub county and to assess the extent to which training influences milk production project among small scale dairy farmers in Bomet East sub -county. The study is of significant to small scale dairy farmers through the Ministry of Livestock and Fisheries on reducing unemployment, improvement of livelihood among dairy farmers and boosting economy as a county as well as reducing poverty as well as basis for scholars for further research. The study was granted the basic assumption that the respondent were able to give information objectively and honestly. Moreover, the study was also based on the assumption that data collection instrument was reliable as valid in taking the desired outcomes. The study was enhanced on the social- Psychology Theory of Reasoned Action (TRA) and Theory of Culture of Poverty. The target population was 4,004 small scale dairy farmers. The researcher adopted in the study probability sampling design which achieved 404 respondents by employing stratified random sampling technique package in descriptive survey design. The compost of 400 farmers, three livestock officer and an official from KDB. The data collected was analyzed using SSPS version 20. The successful returned questioners are 400 respondents (99%).The finding showed that most of those who practice dairy farming are male(60) of age 26-35 years(32%).90 are married individual and most (68%) are of primary and below in education level The findings also showed that most have cross breed dairy cattle utilizing natural mating. The major market for their milk is neighbors and local shop/hotel of less than 1 km from their farms. Service as per the finding from Government livestock officers are poor(46) and most (40%) get training from GOK. Due to level of education and conduct with officers, the major source of information is through media(local radio station, Kass FM or Chamke FM)(40%). It is recommended the promotion of gender balance have to be promote and embrace ICT technology on transmitting information. Further research has to be made on how cooperatives are to promote milk production project.

Paper Title :: Comparison between software and hardware control in PSM mode of a Buck converter

The control of a DC-DC converter is generally done through a circuit comprising logic and analog components. In the presented work, we have ordered a Buck converter in two different ways. The first method consists in using a control in the form of an electrical circuit . The second method is based on the control of the converter through a programmable circuit. The program introduced in the form of a MATLAB embedded function and simulated under SIMULINK / MATLAB gave results similar to those obtained using the control made with a conventional electrical circuit. For the control, we chose the PSM mode (Pulse Skipping Modulation). It is an efficient and simple control to realize both in the form of an electrical circuit and under programming. The comparison of the results obtained under SIMULINK / MATLAB enabled us to highlight the advantages and disadvantages of each method.
Keywords: Buck Converter, PSM Mode, Programmable control, MATLAB embedded function.
