Lydia H. Hart Diary
Full text linkDiary, 1823-1830, 1875 and loose papers 1813, 1831, and undated of Lydia H. Hart of Richmond, Virginia and later Walden, Orange County, New York. The Diary was started by Lydia H. Hart, the wife of Reverend William H. Hart, who was the rector of St. John’s Church in Richmond, VA and later St. Andrews Church in Walden, New York. Diary entries include day-to-day activities and meetings with local neighbors and church patron’s. These neighbors included Elizabeth Van Lew and her parents, which Lydia Hart writes about several times. Most dated entries also include discussion of specific bible verses or Rev. Hart’s sermons. Notable entries include a description of the funeral service for Rev. John Buchanan, former rector of St. John’s Church from 1795 to 1822. Diary entries are chronological and more frequent for 1823 and become less frequent in 1823. In 1828, Lydia Hart moved to New York and eventually to Walden, New York in May 1830.At the end of the diary entries is an entry form another author, possibly by Mary. W. Hart dated 1875. Lydia Hart died in 1831 and could not have made the entry.At the back of the diary and upside down to the diary entries are transcriptions of letters and poems of Lydia Hart’s to various newspapers and and personnel correspondence. Entries include a plea for support to the city of Richmond to take care of its ‘destitute children’, letters to the editor of local newspapers, and poems for the birth of a child or death of a patron.Loose papers include a letter dated Jan 8th 1813, a bequeath request from William H. Hart for the placement of a Tombstone for Lydia Hart, a table of contents for various letters or sermons, a letter from William Hart to a friend from Richmond, and 2 loose undated papers of unknown authorship. The letter from William Hart speaks of the events of Lydia’s death, and inquiries about events taking place in Richmond
Contribution of Information and Communication Technology (ICT) in Country’S H-Index
Full text linkThe aim of this study is to examine the effect of Information and Communication Technology (ICT) development on country’s scientific ranking as measured by H-index. Moreover, this study applies ICT development sub-indices including ICT Use, ICT Access and ICT skill to find the distinct effect of these sub-indices on country’s H-index. To this purpose, required data for the panel of 14 Middle East countries over the period 1995 to 2009 is collected. Findings of the current study show that ICT development increases the H-index of the sample countries. The results also indicate that ICT Use and ICT Skill sub-indices positively contribute to higher H-index but the effect of ICT access on country’s H-index is not clear
ROBUST STABILITY, STABILISATION AND H-INFINITY CONTROL FOR PREMIUM-RESERVE MODELS IN A MARKOVIAN REGIME SWITCHING DISCRETE-TIME FRAMEWORK
Full text linkThe premium pricing process and the medium- and long-term stability of the reserve policy under conditions of uncertainty present very challenging issues in relation to the insurance world. Over the last two decades, applications of Markovian regime switching models to finance and macroeconomics have received strong attention from researchers, and particularly market practitioners. However, relatively little research has so far been carried out in relation to insurance. This paper attempts to consider how a linear Markovian regime switching system in discrete-time could be applied to model the medium- and long-term reserves and the premiums (abbreviated here as the P-R process) for an insurer. Some recently developed techniques from linear robust control theory are applied to explore the stability, stabilisation and robust H∞-control of a P-R system, and the potential effects of abrupt structural changes in the economic fundamentals, as well as the insurer's strategy over a finite time period. Sufficient linear matrix inequality conditions are derived for solving the proposed sub-problems. Finally, a numerical example is presented to illustrate the applicability of the theoretical results
A comparative study of the Finnish 4-H organization and the Wisconsin 4-H organization
Full text linkPlan BThe education of today’s youth, tomorrow’s future, is the focus of the 4-H organization. The aim of the 4-H program is to develop life skills in youth using hands-on learning. 4-H began in the heartland of America in the early 1900’s and soon stretched around the globe. 4-H or a partner organization of 4-H can be found in over 63 countries in the world (V. Gobeli, personal communication, February 25, 2002). The programming, structure, and principles of 4-H programs around the world are all based on the program that began in the United States, but the methods used are different in every country. It is even different among states in the United States. Each program has unique ideas used in the education of youth, but little communication exists to share these ideas among countries. The purpose of this study is to compare another country’s 4-H program to the program that has been long established in Wisconsin. The goal of the study is to show the similarities and difference of two programs that have been created using the same theme, “learning by doing.” Due to the scope of this research, the researcher chose to look only at one country. The country of Finland was chosen for comparison because of its location, similar structure, and its well-established example of European youth programming. The researcher looked at the history of the two programs to help establish the similarities and difference that might exist. The Finnish 4-H Federation began after two men visited the United States and observed the success of club work administered by the United States Department of Agriculture. The program ideas were changed to fit the needs of the Finnish people, with the key concept of life skill development remaining the same. The researcher also found that many articles have been written to show an importance in international programming and international travel. The research was done using ethnographic research along with a qualitative written survey and various interviews. The written survey was used to gain basic information before ethnographic research began. The research revealed that although the programs have the same basic goal, the two programs are very different. The largest differences were seen in projects offered, staff roles, leaders participation, and competition. It was found that both 4-H programs contained ideas of superior quality. If these ideas were shared, it could help to improve the program in the other country. The research not only compared the two programs, but also recommended further programs or studies that could be established based on the research performed

A sequence of random variables, all of which are mutually independent but obey the Bernoulli distribution, is introduced to account for the probabilistic communication delays. The measurement-missing phenomenon occurs in a random way. The missing probability for each sensor satisfies a certain probabilistic distribution in the interval. Here, the attention is focused on the analysis and design of H∞ fuzzy output-feedback controllers such that the closed-loop Takagi-Sugeno (T-S) fuzzy-control system is exponentially stable in the mean square. The disturbance-rejection attenuation is constrained to a given level by means of the H∞-performance index. Intensive analysis is carried out to obtain sufficient conditions for the existence of admissible output feedback controllers, which ensures the exponential stability as well as the prescribed H∞ performance. The cone-complementarity-linearization procedure is employed to cast the controller-design problem into a sequential minimization one that is solved by the semi-definite program method. Simulation results are utilized to demonstrate the effectiveness of the proposed design technique in this paper.This work was supported in part by the Engineering and Physical Sciences Research Council, U.K., under Grant GR/S27658/01, in part by the Royal Society, U.K., in part by the National Natural Science Foundation of

Probability-guaranteed H∞ finite-horizon filtering for a class of nonlinear time-varying systems with sensor saturations
No full textThis is the Post-Print version of the Article. The official published version can be accessed from the link below - Copyright @ 2012 ElsevierIn this paper, the probability-guaranteed H∞ finite-horizon filtering problem is investigated for a class of nonlinear time-varying systems with uncertain parameters and sensor saturations. The system matrices are functions of mutually independent stochastic variables that obey uniform distributions over known finite ranges. Attention is focused on the construction of a time-varying filter such that the prescribed H∞ performance requirement can be guaranteed with probability constraint. By using the difference linear matrix inequalities (DLMIs) approach, sufficient conditions are established to guarantee the desired performance of the designed finite-horizon filter. The time-varying filter gains can be obtained in terms of the feasible solutions of a set of DLMIs that can be recursively solved by using the semi-definite programming method. A computational algorithm is specifically developed for the addressed probability-guaranteed H∞ finite-horizon filtering problem. Finally, a simulation example is given to illustrate the effectiveness of the proposed filtering scheme.This work was supported in part by the National Natural Science Foundation of China under Grants 61028008, 60825303 and
