Optimization of a Neutrino Factory: Discovery Machine versus Precision Instrument

We discuss the optimization of a neutrino factory experiment for the purpose of sin^2(2theta_13), mass hierarchy, and CP violation discoveries. This includes a review of possible optimization strategies, as well as an application of these to different sin^2(2theta_13) regions.Comment: 5 pages, 4 figures.

Systematic Model Building Based on Quark-Lepton Complementarity Assumptions

In this talk, we present a procedure to systematically generate a large number of valid mass matrix textures from very generic assumptions. Compared to plain anarchy arguments, we postulate some structure for the theory, such as a possible connection between quarks and leptons, and a mechanism to generate flavor structure. We illustrate how this parameter space can be used to test the exclusion power of future experiments, and we point out that one can systematically generate embeddings in Z_N product flavor symmetry groups.Comment: 3 pages, 1 figure.

Neutrino oscillations: present status and outlook

I summarize the status of three-flavour neutrino oscillations with date of Oct. 2007, and provide an outlook for the developments to be expected in the near future. Furthermore, I discuss the status of sterile neutrino oscillation interpretations of the LSND anomaly in the light of recent MiniBooNE results, and comment on implications for the future neutrino oscillation program.Comment: 6 pages, 5 figures, plenary talk at NuFact07, Okayama, Japa

Charged Lepton Flavour Violation in Littlest Higgs model with T-parity

The Little Higgs model with T-parity (LHT) belongs to the non-minimal flavour violating model. This model has new sources of flavour and CP violation both in quark and leptonic sectors. These new sources of flavour violation originates by the interaction of Standard Model (SM) fermions with heavy gauge bosons and heavy (or mirror) fermions. In this work we will present the impact of the new flavour structure of T-parity models on flavour violations in leptonic sector.Comment: 3 pages, no figures, Talk given at NuFact07, Aug 6-11, 2007, Okayama, Japan, references adde

Evaluation-Function-based Model-free Adaptive Fuzzy Control

Designs of adaptive fuzzy controllers (AFC) are commonly based on the Lyapunov approach, which requires a known model of the controlled plant. They need to consider a Lyapunov function candidate as an evaluation function to be minimized. In this study these drawbacks were handled by designing a model-free adaptive fuzzy controller (MFAFC) using an approximate evaluation function defined in terms of the current state, the next state, and the control action. MFAFC considers the approximate evaluation function as an evaluative control performance measure similar to the state-action value function in reinforcement learning. The simulation results of applying MFAFC to the inverted pendulum benchmark veriï¬ed the proposed scheme's efficacy

More on Non-standard Interaction at MINOS

We discuss about effects of the non-standard interaction of neutrinos with matter on the nu_e appearance search in the MINOS experiment. We consider the effects of the complex phase of the interaction and of the uncertainty on theta_23 also. We show that the oscillation probability can be so large that can not be explained by the ordinary oscillation. We show also how much constraints on the non-standard effects can be improved if the experiment does not observe nu_e appearance signal.Comment: Talk given at 9th International Workshop on Neutrino Factories, Superbeams and Betabeams (NuFact07), Okayama, Japan, 6-11 Aug 200

Assessment of Risk Factors for Type II Diabetes Mellitus on Patients Attending at Three Hospitals in Wolaita Zone, South Ethiopia

Diabetes mellitus is one of the most common chronic metabolic disorders of carbohydrates, proteins and fat in almost all countries, and it continues to be increased in magnitude and clinical significance, as lifestyle changes lead to reduce physical activity and increased obesity. A cross sectional study was conducted from July1 to August 15, 2011 in three Hospitals of Wolaita Zone using purposive sampling technique until required sample size of 348 was achieved. Patients with type II diabetes mellitus were selected based on sample size determination technique for single population. Data were collected using semi-structured questionnaire. The data was analyzed by using SPSS version 16.0. Frequencies and graphs were used to describe selected variables.348 study subjects have participated in the study. As per the age distributions 188 (54 %) of study participants were found to be above age of 50 years. The mean ± SD age of type II patients was 51.9±13.6 and age range between 19 years and 83 years. Hundred and seventy nine (51.4%) of the study participants were males. With respect to educational levels 86 (24.7%) of the study participants have completed primary school (grade 1-4) followed by illiterates 75 (21.6%). Regarding income, 106 (30.5%) of type II diabetic patients have monthly income more than 1500 ETB. A high proportion of risk factors observed in type II diabetes mellitus were   being male, older age group greater than 50, overweight and with higher monthly income. The risk rate of type II diabetes mellitus was higher among urban residence, primary level of education. Most of the diabetic cases had BMI >25 kg/m2 which is a risk factor for the development of type II Diabetes.
