A minimal renormalizable SUSY SO(10) model with B-L symmetry broken by 126 Higgs field has recently been shown to predict all neutrino mixings and the ratio ∆m⊙/∆m 2 A in agreement with observations. Unlike models where B-L is broken by 16 Higgs, this model guarantees automatic R-parity conservation and hence a stable dark matter without any additional symmetry assumptions. In this paper, we di...
background: turkey, especially the northern part of it, was one of the countries which were contaminated by the chernobyl accident. rize is a city located in the northeastern district of turkey which was heavily influenced by the chernobyl nuclear accident. materials and methods: in this study, the activity concentrations of natural (226ra, 232th, 40k) and artificial (137cs) were measurements ...
following the changes in the paradigm of urban studies in recent years, sustainability has become an increasingly important issue in the neighborhood’s planning and designing. however, this concept has originally been developed for american and european neighborhoods’ planning, it could also be customized for other neighborhoods’. additionally, in the neighborhood scale, the quality parameter f...
We develop how a notion of e ective scale can be introduced in a formal way. For continuous signals a scaling argument directly gives that a natural unit for measuring scale-space lifetime is in terms of the logarithm of the ordinary scale parameter. That approach is, however, not appropriate for discrete signals, since then an in nite lifetime would be assigned to structures existing in the or...
In this paper, acceptance sampling plans are developed for the odds exponential log logistic distribution (OELLD) introduced by Rosaiah et al. [1] based on lifetime percentiles when the life test is truncated at a predetermined time. The minimum sample size necessary to ensure the specified lifetime percentile is obtained under a given customer’s risk. The operating characteristic values of the...
Breast cancer is the most common cause of cancer deaths among Australian women. In NSW in 1999, 3,463 women were newly diagnosed with breast cancer. The average lifetime risk of breast cancer is about one in 11 women. Each year, over 2,600 women in Australia die from the disease. It is estimated that it costs Australia $169.5 million to diagnose and treat the disease and there are considerable ...
This paper discusses the CRISTAL object lifecycle management system and its use in provenance data management and the traceability of system events. This software was initially used to capture the construction and calibration of the CMS ECAL detector at CERN for later use by physicists in their data analysis. Some further uses of CRISTAL in different projects (CMS, neuGRID and N4U) are presente...
Although many approaches for architecturebased reliability estimation exist, these approaches are typically limited to certain classes or exclusively concentrate on software reliability, neglecting the influence of hardware resources, component reliability, component replica and software deployment. In this paper, a reliability estimation model based on software architecture (SA) is presented. ...
Does experimental evidence of the common difference effect imply that intertemporal preferences are time inconsistent? Do these features of choice suggest inherent characteristics of preferences, or could they be traced to an underlying factor that shapes the environment? The effect of uncertain lifetime on intertemporal preferences is studied. A demographic model that allows for unobservable h...
In this paper the authors discuss the misunderstanding that arose over the years around the broadly defined term of the objectrelational mismatch. It occurs in many different aspects of programming. There are three concerns considered the most important: mismatching data models, mismatching binding times and mismatching object lifecycle. This paper focuses on the data model mismatch. The author...
