Abraham Michael Hasofer (1927-2010) was an Australian statistician. Professor Hasofer held the position of the Chair of Statistics within the Mathematics Department in the University of New South Wales in Sydney from 1969 [1] to 1991. He subsequently held a position at the La Trobe University in Melbourne. He authored a number of publications in the field of applied mathematics and civil engineering, including his formulation of the Hasofer-Lind Reliability Index. [2] [3]

Biography

Abraham Hasofer was born in Alexandria, Egypt, on 2 October 1927 [4] to an Ashkenazi Jewish family. He migrated to Israel after the state's independence but subsequently migrated to Australia in 1955. [5] : 58  In the 1960s, Hasofer joined the Chabad Hasidic movement. [6]

Education and career

In 1948, Hasofer earned a bachelor's degree in Electrical Engineering from the University of Alexandria in Egypt. In 1960 he earned a Bachelor of Science from the University of Tasmania, and in 1964, Hasofer earned his PhD in Mathematical Statistics from the University of Tasmania [7] which was the first PhD degree earned in the university's Department of Mathematics. At the time, Hasofer was a lecturer in the department. Hasofer went on to become Professor of Statistics at the University of New South Wales (UNSW). [8] He was chair of statistics within the Mathematics Department for much of his career.

Prior to Hasofer's position at UNSW, he was a resident Fellow of the Australian National University in Canberra from 1955 to 1956. Hasofer and his family remained in Canberra until 1969. [9]

Hasofer was a visiting professor at Massachusetts Institute of Technology (MIT) and Princeton University. [9]

Hasofer received the status of emeritus professor at UNSW. [10] Hasofer died in 2010. [3]

Activities

Hasofer's work in mathematics included the formulation of the advanced statistical method known as the Hasofer-Lind Reliability Index which is recognized as an important step towards the development of contemporary methods to effectively and accurately estimate structural safety. [11] The Hasofer-Lind Reliability Index is more often called the first-order reliability method (FORM) [12] which Hasofer successfully applied as a method to resolving structural problems. [13] Alternatively, it is referred to as the first order second-moment reliability index. [14]

Hasofer's research has been used in the field of fMRI research. [15]

In the Jewish community

While living in Canberra, Michael Hasofer and his wife Atara Hasofer were faced with the challenge of the lack of kosher meat in the Australian capital, a challenge that had discouraged other Orthodox families from residing in the city. Hasofer attended a course on the Jewish ritual laws of the slaughter of poultry (shechitat ofot) and made his services available to the community.[ citation needed ] However, the Jewish community in Canberra took little advantage of the offer. While in Canberra, Hasofer served the Jewish community as a synagogue officiant. He and his wife Atara also served as members of the Education Committee, with Atara establishing a local chapter of the N'shei Chabad, the Habad-Lubavitch Women's Association. [9]

In the Australian Jewish community, Hasofer was the founding president of the Australian chapter of the Association of Orthodox Jewish Scientists (AOJS). [2] [16] [17]

Hasofer supported Dr Lee Spetner's stance on Neo-Darwinism which questioned the plausibility of the evolutionary theory of the appearance of beneficial mutations. Spetner's calculations of the probability of beneficial mutations led him to conclude that is unreasonable to assume that beneficial mutations can be produced even in a generous allocation of geological time. [18] [7]

In the 1990s, Hasofer rejected the validity of Bible codes which he viewed as statistically unfounded. [19] [20] [21]

While teaching at the Australian National University in Canberra, Hasofer researched notions of probability and random mechanisms discussed in Talmudic literature. According to Hasofer, the attitude of Ancient Israel toward chance mechanism was diametrically opposed to that of neighboring nations. Dice had been used for gambling as well as for divination in Greek and Roman temples, while Jews were forbidden and sanctioned for use of dice. Lots were used by Jews to settle disputes, as a fair method to allocate duties among contenders, among other uses. [22] [23] [24] [25] This subject was further researched by Nahum Rabinovitch who explored Talmudic probabilistic notions and chance mechanisms. [26]

A randomized algorithm is an algorithm that employs a degree of randomness as part of its logic or procedure. The algorithm typically uses uniformly random bits as an auxiliary input to guide its behavior, in the hope of achieving good performance in the "average case" over all possible choices of random determined by the random bits; thus either the running time, or the output are random variables.

Reliability engineering is a sub-discipline of systems engineering that emphasizes the ability of equipment to function without failure. Reliability describes the ability of a system or component to function under stated conditions for a specified period. Reliability is closely related to availability, which is typically described as the ability of a component or system to function at a specified moment or interval of time.

Lee M. Spetner is an American and Israeli creationist author, mechanical engineer, applied biophysicist, and physicist, known best for his disagreements with the modern synthesis. In spite of his opposition to neo-Darwinism, Spetner accepts a form of non-random evolution outlined in his 1996 book "Not By Chance! Shattering the Modern Theory of Evolution".

Uncertainty quantification (UQ) is the science of quantitative characterization and estimation of uncertainties in both computational and real world applications. It tries to determine how likely certain outcomes are if some aspects of the system are not exactly known. An example would be to predict the acceleration of a human body in a head-on crash with another car: even if the speed was exactly known, small differences in the manufacturing of individual cars, how tightly every bolt has been tightened, etc., will lead to different results that can only be predicted in a statistical sense.

<span class="mw-page-title-main">Probabilistic design</span> Discipline within engineering design

Probabilistic design is a discipline within engineering design. It deals primarily with the consideration and minimization of the effects of random variability upon the performance of an engineering system during the design phase. Typically, these effects studied and optimized are related to quality and reliability. It differs from the classical approach to design by assuming a small probability of failure instead of using the safety factor. Probabilistic design is used in a variety of different applications to assess the likelihood of failure. Disciplines which extensively use probabilistic design principles include product design, quality control, systems engineering, machine design, civil engineering and manufacturing.

Computational statistics, or statistical computing, is the study which is the intersection of statistics and computer science, and refers to the statistical methods that are enabled by using computational methods. It is the area of computational science specific to the mathematical science of statistics. This area is fast developing. The view that the broader concept of computing must be taught as part of general statistical education is gaining momentum.

A probability box is a characterization of uncertain numbers consisting of both aleatoric and epistemic uncertainties that is often used in risk analysis or quantitative uncertainty modeling where numerical calculations must be performed. Probability bounds analysis is used to make arithmetic and logical calculations with p-boxes.

The first-order reliability method, (FORM), is a semi-probabilistic reliability analysis method devised to evaluate the reliability of a system. The accuracy of the method can be improved by averaging over many samples, which is known as Line Sampling.

Probability bounds analysis (PBA) is a collection of methods of uncertainty propagation for making qualitative and quantitative calculations in the face of uncertainties of various kinds. It is used to project partial information about random variables and other quantities through mathematical expressions. For instance, it computes sure bounds on the distribution of a sum, product, or more complex function, given only sure bounds on the distributions of the inputs. Such bounds are called probability boxes, and constrain cumulative probability distributions.

P-boxes and probability bounds analysis have been used in many applications spanning many disciplines in engineering and environmental science, including:

Subset simulation is a method used in reliability engineering to compute small failure probabilities encountered in engineering systems. The basic idea is to express a small failure probability as a product of larger conditional probabilities by introducing intermediate failure events. This conceptually converts the original rare-event problem into a series of frequent-event problems that are easier to solve. In the actual implementation, samples conditional on intermediate failure events are adaptively generated to gradually populate from the frequent to rare event region. These 'conditional samples' provide information for estimating the complementary cumulative distribution function (CCDF) of the quantity of interest, covering the high as well as the low probability regions. They can also be used for investigating the cause and consequence of failure events. The generation of conditional samples is not trivial but can be performed efficiently using Markov chain Monte Carlo (MCMC).

Structural reliability is about applying reliability engineering theories to buildings and, more generally, structural analysis. Reliability is also used as a probabilistic measure of structural safety. The reliability of a structure is defined as the probability of complement of failure . The failure occurs when the total applied load is larger than the total resistance of the structure. Structural reliability has become known as a design philosophy in the twenty-first century, and it might replace traditional deterministic ways of design and maintenance.

<span class="mw-page-title-main">Deterioration modeling</span> Engineering formula

Deterioration modeling is the process of modeling and predicting the physical conditions of equipment, structures, infrastructure or any other physical assets. The condition of infrastructure is represented either using a deterministic index or the probability of failure. Examples of such performance measures are pavement condition index for roads or bridge condition index for bridges. For probabilistic measures, which are the focus of reliability theory, probability of failure or reliability index are used. Deterioration models are instrumental to infrastructure asset management and are the basis for maintenance and rehabilitation decision-making. The condition of all physical infrastructure degrade over time. A deterioration model can help decision-makers to understand how fast the condition drops or violates a certain threshold.

In the mathematical theory of probability, a generalized renewal process (GRP) or G-renewal process is a stochastic point process used to model failure/repair behavior of repairable systems in reliability engineering. Poisson point process is a particular case of GRP.
