Optimal Demand-Side Management for Smart Micro Grid with Storage  [PDF]
Hugor Ininahazwe, Christopher Maina Muriithi, Stanley Kamau
Journal of Power and Energy Engineering (JPEE) , 2018, DOI: 10.4236/jpee.2018.62004
Abstract: In this paper, an autonomous and distributive demand-side management based on Bayesian game theory is developed and applied among users in a grid connected micro-grid with storage. To derive that strategy, an energy consumption of shiftable loads belonging to a given user is modelled as a noncooperative three-player game of incomplete information, in which each user plays against the storage unit and an opponent gathering all the other users in the micro-grid. Each player is assumed to be endowed with statistical information about its behavior and that of its opponents so that he can take actions maximizing his expected utility. Results of the proposed strategy evaluated by simulating, under MATLAB environment, a connected micro-grid with storage device evidence its efficacy when employed to manage the charging of electric vehicles.
Effects of Guerilla Marketing in Growth of Beauty Shops: Case Study of Matuu Town, Machakos County, Kenya
Stanley Mwangi Kamau,Henry M. Bwisa
International Journal of Academic Research in Business and Social Sciences , 2013,
Abstract: Marketing in small firms is not the simplistic, promotional activity that it appears at first sight. Nor is it marketing according to the traditional concepts. Marketing indicate that an assessment of market needs comes before new product or service development The purpose of the study is to assess the effects of guerilla marketing practices on the growth of beauty shops in Matuu town, Machakos County. Kiambu County was selected due to the fact that it has a very high level of competition in beauty shop business and therefore, the owners have turned to guerilla marketing tactics to reach to their customers.This study targets the population of beauty shop owners, focus groups and the clients of the business. Random sampling was used to identify the 27 businesses was focused by the study. The research design used was exploratory research since much has not been done in area of interest. The questionnaire comprised of closed and open ended questions. Descriptive statistics was used to collect data and included frequency tables and charts. Further, a computer statistical package for social sciences (SPSS) was used in entering and analyzing the data. The study established that the beauty shop owners used guerilla marketing to promote their businesses.
Roll Back Malaria and the new partnership for Africa\'s development: Is there potential for synergistic collaboration in partnerships?
EM Kamau
African Journal of Health Sciences , 2006,
Abstract: This synopsis seeks to highlight and promote the enormous potential that exists between these two initiatives that seek to address closely related issues and targeting the same populations at risk within a fairly well defined geographical setting. It also attempts to argue that malaria control, just like HIV-Aids control be given high priority in the New Partnership for Africa\'s Development (NEPAD) health agenda, as current statistics indicate that malaria is again on the rise. While much attention and billions of dollars have rightly been given to HIV-Aids research, treatment and prevention, malaria, and not Aids, is the region\'s leading cause of morbidity and mortality for children under the age of five years. This is the bad news. The good news is that unlike Aids, malaria treatment and prevention are relatively cheap. In addition, there is a payback to fighting malaria; support aimed directly at improving health, rather than poverty reduction, may be a more effective way of helping Africa to thrive. Robust and sustained growth may come to Africa through a mosquito net, Artemisinin-based Combination Therapies (ACTs) or a malaria vaccine, rather that a donor\'s cheque for economic development initiatives.

Malaria diagnosis in the community: Challenges and potential role of rapid diagnostic tests (RDTs) in the African Region.
EM Kamau
African Journal of Health Sciences , 2007,
Abstract: At present, malaria rapid diagnostic tests (RDTs) are widely available and used in parts of Asia and Latin America. In Africa, their use has been limited mainly to private health facilities. With the adoption of artemisinin combination therapies (ACTs) by most African countries as first line treatment for malaria, an effective, but expensive treatment is available, and the case for an expanded role for rapid diagnostics in the fight against malaria is clear. Despite this perceived potential role for RDTs, some challenges hinder their introduction and scale-up in the public health sector. Among the requirements are significant investments in policy development, training, infrastructure, and supply chain and quality assurance systems.

Kiswahili, utandawazi na umoja wa Afrika
SJ Kamau
Journal of Language, Technology & Entrepreneurship in Africa , 2009,
Abstract: It is a fact that in the recent past, globalization has gradually taken shape in Africa and as such the continent has no choice but to embrace this development. In order for Africa to benefit fully from globalization, various measures must be taken. One of the key measures is the use of one indigenous African language to serve as an official and unifying language throughout the continent. We argue that the language with that potential is Kiswahili. This paper sets out to evaluate the place of Kiswahili as a unifying language in Africa in the era of a globalizing Africa. Globalization in Africa has to do with the coming together of African nations to form a bloc that will cooperate in the social, political and economic fronts. This being the case, the need for a common African language for use across the continent cannot be ignored. The best placed African language, as this paper will demonstrate, is Kiswahili.

A digital divide: Kiswahili holds the key
SN Kamau
Journal of Language, Technology & Entrepreneurship in Africa , 2007,
Abstract: With today's increased use of Information and Communication Technologies (ICT), the world has been turned into a global village courtesy of the easy and fast means of communication over vast geographical distances (Katembo 2005). However, not all the regions in the world are included in the ‘global village'. Most developing countries especially in Africa are yet to make a mark in the ICT domain. Due to this fact there exists a digital divide between the developed and the developing nations of the world.

Navigating laboratory services quality in challenging environments: A perspective for implementation in small, low-income countries and post-conflict settings
Edward M. Kamau
African Journal of Laboratory Medicine , 2013,
Abstract: The need to establish and maintain good laboratory practices is recognised universally. However, due to differences in resources available for health services in different countries, allocation of financial and human resources in poor countries is severely constrained. The constraints faced by poor countries call for innovative approaches that would guarantee the minimum acceptable quality while striving to meet the highest standards. In resource-limitedsetting, it may be justifiable to develop and use ‘fit for purpose’ quality standards based on internationally-recognised laboratory quality management frameworks or protocols.

Abstract: The main objective of the study is to investigate intermediation efficiency and productivity in the banking sector in the post liberalization period in Kenya. The study is motivated by the fact that though the banking sector constitutes a large part of the financial system in Kenya, little is known about its intermediation efficiency and productivity status. Further banks are awash with liquidity despite private sector credit demand indicating some inefficiency in the intermediation process in Kenya. This study adopts a non-parametric Data Envelopment Analysis (DEA) to analyze intermediation efficiency in the banking sector and Malmquist Productivity Index (MPI) to measure productivity gains of banks in Kenya. The results show that though the banks were not fully efficient in all respects, they performed fairly well during the period under study. Banks still have reason and scope to improve performance by improving their technology, skills and enlarging their scale of operations so as to be fully efficient. Based on the main conclusions, policies encouraging competition, products diversification to advance loans, risks minimization through increased capital regulation and privatization of some banks are generally recommended.
A Review of Users Adoption of Open Source Software in Africa
John Kamau,Sylvester Namuye
Computer and Information Science , 2012, DOI: 10.5539/cis.v5n5p45
Abstract: In the current world, software is increasingly becoming important in the human activity. It is widely recognised that Open Source software (OSS) is freely available to anyone who needs it. However, loyalty of computer users to proprietary operating systems and general office applications seems to be still high especially in developing countries. OSS has a great potential of saving costs for developing economies in Africa and reducing the cost of doing business and automating operations. The software would be very useful especially in the current period of economic hardships being faced by many developing countries. African governments have also not taken the lead in adopting the OSS software and many do not have policies in place regarding it. A review of literature on studies conducted in Africa on OSS in order to establish the level of user adoption, possible barriers to OSS adoption in developing countries in Africa is done in this paper. The findings are of great value to all stakeholders, namely the software developers, policy makers and computer experts in their endeavour to achieve high user adoption of OSS.
Left Atrial Volume Index in Patients with Dilated Cardiomyopathy—Correlation with Left Ventricular Function  [PDF]
Stanley George
World Journal of Cardiovascular Diseases (WJCD) , 2016, DOI: 10.4236/wjcd.2016.69035
Abstract: Background: The aim of this study was to determine the relation of left atrial (LA) volume and LA volume index with left ventricular function and to determine the association of duration of symptoms and left atrial volume index in patients with dilated cardiomyopathy. Materials and Methods: This was an observational, single centre study conducted in India. A total of 50 patients who were admitted to department of cardiology from July, 2008 to February, 2009 with diagnosis of dilated cardiomyopathy and an ejection fraction of <40% were included. Results: Of the 50 patients, 34 (68%) were males. 27 (54%) patients were in NYHA class II and 23 (46%) patients were in NYHA class III. LA volume was found to be ≥40 ml in all patients. LV function and LA volume were found to be correlated (r = -0.789, p < 0.01). Similarly, there was a correlation between LV function and LA volume index (r = -0.826, p < 0.01). There was no correlation between LA volume index and duration of symptoms (r = 0.04). Conclusion: It can be concluded that there is a strong inverse correlation between LA volume and left ventricular function and also between LA volume index and left ventricular function. The patients with NYHA class III were having larger left atrial volume than those with NYHA class II. Moreover, the duration of symptoms has no correlation with left atrial volume index.
