epi immunization coverage timeliness and Dropout Rate among children in a west cameroon health district a cross sectional study
BMC Public Health, 2020Co-Authors: Jerome Ateudjieu, Martin Ndinakie Yakum, Andre Pascal Goura, Ayok Maureen Tembei, Douanla Koutio Ingrid, Beyala Bitaa Landry, Bruno Kenfack, Lapia Amada, Isaac Tadzong, Anne Cecile BissekAbstract:Monitoring of the expanded program on immunization’s performance is not only limited to routine periodic reports but equally includes surveys. Based on unpublished national EPI surveillance data from the past 5 years in Cameroon, the Foumban health district has reported a high number of vaccine preventable disease suspected cases. Contradictory information on the immunization coverage in this district exists from both administrative data and published literature. As a result, the objective of this study was to estimate the immunization coverage and Dropout Rate in age group 12–23 months and timeliness in age group 0–59 months among children in Foumban Health District (Cameroon), in 2018. This was a descriptive cross-sectional study targeting randomly selected children aged 0–59 months from Foumban health district. Data were collected by trained and supervised surveyors using a pretested questionnaire to describe the immunization coverage, timeliness and Dropout Rate in eighty clusters of about thirty buildings selected by stratified random sampling in July 2018. In total, 80 clusters covering 2121 buildings were selected and all were reached (100%). A total of 1549 (81.2%) households accepted to participate in the survey and 1430 children aged 0–59 months including 294 (20.6%) aged 12–23 months were enrolled into the study. Of these 1430 children, 427 [29.9 (27.4–32.2)%] aged 0–59 months were vaccinated with evidence. In the age group 12–23 months, the immunization coverage with evidence of BCG, DPT-Hi + Hb 3 and measles/rubella were 28.6(23.4–33.9)%, 22.8 (18.1–27.6)% and 14.3 (10.3–18.1)% respectively. Within age group 0–59 months; the proportion of children who missed their vaccination appointments increased from 23.3 to 31.7% for the vaccine planned at birth (BCG) and last vaccine planned (Measles/Rubella) for the EPI program respectively. In age group 12–23 months; the specific (DPT-Hi + Hb1–3) and general (BCG-Measles/Rubella) Dropout Rates of vaccination with evidence were 14.1 and 50.0% respectively. Documented immunization coverage, Dropout Rate and timeliness in Foumban Health district are lower than that targeted by the Cameroon EPI. Competent health authorities have to take necessary actions to ensure the implementation of national guidelines with regards to children access to immunization. Also, studies have to be conducted to identify determinants of low immunization coverage and delays in immunization schedules as well as high Dropout Rates.

hybrid filter design of fault detection for networked linear systems with variable packet Dropout Rate
Iet Control Theory and Applications, 2019Co-Authors: Dongzhe Wang, Xueheng Mei, Rui Weng, Lixian ZhangAbstract:The study focuses on the fault detection filter design problem for a class of networked systems with intermittent measurements. The fault detection filter, which is used as residual generator, is formulated as an $\mathcal {H} _{\infty }$H ∞ filtering form. The random packet Dropouts are governed by a Bernoulli distributed sequence, and the packet Dropout Rate is uncertain and variable, which is described by a semi-Markov stochastic process. A more general class of Lyapunov functions that not only depend on the system modes, but also on the staying time during the current system mode is utilised. Afterwards, numerically testable sufficient conditions on the existence of a desired fault detection filter are established such that the filtering error system is $\sigma $σ-error mean square stable with a prescribed $\mathcal {H}_{\infty }$H ∞ disturbance attenuation level. Finally, an illustrative example is provided not only to demonstRate the effectiveness of the designed filter and the superiority of the utilisation of semi-Markov chain, but also the necessity of considering the variation of packet Dropout Rate in the design phase.

fault detection for networked systems with variable packet Dropout Rate
International Conference on Intelligent Control and Information Processing, 2016Co-Authors: Xueheng Mei, Bo Cai, Lixian ZhangAbstract:The paper focuses on the H ∞ fault detection problem for a class of networked systems with intermittent measurements. The fault detection filter (FDF) design is formulated as an H ∞ filtering problem by using a FDF. The random packet Dropouts, which are described by a Bernoulli distributed sequence, are considered to exist in the communication channels. The packet Dropout Rate (PDR) is uncertain and variable, which is described by a Markov stochastic process. Based on mode-dependent Lyapunov function, sufficient conditions on the existence of a desired FDF are presented such that the filtering error system is stochastically mean-square stable with a prescribed H ∞ disturbance attenuation level. Finally, an illustrative example is provided to demonstRate the effectiveness of the designed filter and the necessity of taking the uncertainty and variation of PDR into account in the design process.

distributed filtering for fuzzy time delay systems with packet Dropouts and redundant channels
Systems Man and Cybernetics, 2016Co-Authors: Lixian Zhang, Zepeng Ning, Zidong WangAbstract:This paper is concerned with the distributed H ∞ filtering problem for a class of discrete-time Takagi-Sugeno fuzzy systems with time-varying delays. The data communications among sensor nodes are equipped with redundant channels subject to random packet Dropouts that are modeled by mutually independent Bernoulli stochastic processes. The practical phenomenon of the uncertain packet Dropout Rate is considered, and the norm-bounded uncertainty of the packet Dropout Rate is asymmetric to the nominal Rate. Sufficient conditions on the existence of the desired distributed filters are established by employing the scaled small gain theorem to ensure that the closed-loop system is stochastically stable and achieves a prescribed average H ∞ performance index. Finally, an illustrative example is provided to verify the theoretical findings.

input output approach to control for fuzzy markov jump systems with time varying delays and uncertain packet Dropout Rate
IEEE Transactions on Systems Man and Cybernetics, 2015Co-Authors: Lixian Zhang, Zepeng Ning, Peng ShiAbstract:This paper is concerned with $\boldsymbol {H}_{\infty }$ control problem for a class of discrete-time Takagi–Sugeno fuzzy Markov jump systems with time-varying delays under unreliable communication links. It is assumed that the data transmission between the plant and the controller are subject to randomly occurred packet Dropouts satisfying Bernoulli distribution and the Dropout Rate is uncertain. Based on a fuzzy-basis-dependent and mode-dependent Lyapunov function, the existence conditions of the desired $\boldsymbol {H}_{\infty }$ state-feedback controllers are derived by employing the scaled small gain theorem such that the closed-loop system is stochastically stable and achieves a guaranteed $\boldsymbol {H}_{\infty }$ performance. The gains of the controllers are constructed by solving a set of linear matrix inequalities. Finally, a practical example of robot arm is provided to illustRate the performance of the proposed approach.
