Geomorphic process modeling allows us to evaluate different methods for estimating moraine ages from cosmogenic exposure dates, and may provide a means to identify the processes responsible for the excess scatter among exposure dates on individual moraines. Cosmogenic exposure dating is an elegant method for estimating the ages of moraines, but individual exposure dates are sometimes biased by geomorphic processes. Because exposure dates may be either “too young” or “too old,” there are a variety of methods for estimating the ages of moraines from exposure dates. In this paper, we present Monte Carlo-based models of moraine degradation and inheritance of cosmogenic nuclides, and we use the models to examine the effectiveness of these methods. The models estimate the statistical distributions of exposure dates that we would expect to obtain from single moraines, given reasonable geomorphic assumptions. The model of moraine degradation is based on prior examples, but the inheritance model is novel. The statistical distributions of exposure dates from the moraine degradation model are skewed toward young values; in contrast, the statistical distributions of exposure dates from the inheritance model are skewed toward old values. Sensitivity analysis shows that this difference is robust for reasonable parameter choices. Thus, the skewness can help indicate whether a particular data set has problems with inheritance or moraine degradation.

In this paper we introduce a real-time extension of the concurrent object modeling language Creol which is based on duration statements indicating best and worst case execution times and deadlines. We show how to analyze schedulability of an abstraction of real-time concurrent objects in terms of timed automata. Further, we introduce techniques for testing the conformance between these behavioral abstractions and the executable semantics of Real-Time Creol in Real-Time Maude.
As a case study we model and analyze the schedulability of thread pools in an industrial communication platform.

Academy Award winner Ben Affleck will join a star-studded lineup for their inaugural pop-culture themed Celebrity Fan Fest event. Maybe Shauna Sexton has learned a powerful lesson about the hazards of dating an A-list movie star who is in the midst of a mid-life crisis. Oh, and Warner Bros. The studio opted to rethink its approach to future movies based on DC Comics characters and to seek a different — and perhaps younger?
Sometimes, Affleck also wanted to enjoy a pricey meal at Nobu in Malibu, and sometimes he was in the mood for Jack in the Box. From tabloid photos, it appears that Sexton tried to accommodate his different moods — as well as food cravings — before and during his time in rehab. Affleck finally came to that realization in mid-October, according to reports. He will date in the future, but for now his focus is on his sobriety, family and his next project. He began work on the film in late October.
Recent tabloid photos have showed him co-parenting with Garner, attending church with her and the children. Affleck, Garner and their children also enjoyed Thanksgiving together as a family in Montana, People reported.

Due to the real and perceived dangers of online dating, the stigma that surrounds it, and the pervasiveness of it, it is a great lens through which folks can be introduced to the core principles of threat modeling. Isaiah Sarju has used online dating sites such as Tinder and OkCupid. At times this seems antithetical to his stance on privacy and security. To better understand the security ramifications of online dating, and to establish safe methods of doing it, he applied threat modeling to online dating.
Recently, Bayesian statistical software has been developed for age-depth modeling (“wiggle-match dating”) of sequences of densely spaced radiocarbon dates.

Dating Concurrent Objects: Real-Time Modeling and Schedulability Analysis
It might be hard to imagine or remember, but there was once a time when going on a date with a stranger you met online was a strange concept—frowned upon, even. Today, however, millennials have led the charge on transforming the dating industry and making online dating universally accepted. If you continue to have doubts, consider that there are now over 1, dating apps or websites looking to draw single men and women to their product, and to match them with one another.

NASH University of Cincinnati ABSTRACT The pattern of degradation observed on some scarps formed by normal, range-front faulting of alluvial fan surfaces may be accurately modeled, and, when properly calibrated, these models provide a means for determining the ages of some scarps morphologic dating.
Two different degradation patterns are observed: some scarps recline, becoming more rounded with time, whereas others retreat with little or no decrease in gradient. Scarps that recline are generally covered with soil or loosened debris and are termed transport-limited because more loosened debris is produced than the transport processes are capable of removing.
Retreating scarps are generally stripped bare of debris and are termed loosening-limited because debris is carried away as rapidly as it is loosened from the surface. These two different modes of degradation require two fundamentally different models.
Let’s Model Radioactive Decay to Show How Carbon Dating Works
The application of Bayesian statistics is probably the single biggest development in chronology building over the past 20 years and a key part of the PalaeoChron dating approach. INTCAL13 , the most recently published internationally-agreed radiocarbon calibration curve, extends back to 50, cal BP, but single calibrated ages result in wide probability distributions that are often only coarsely useful. Bayesian modelling and the construction of robust probabilistic frameworks help us address questions that presently are not possible to answer due to dating imprecision.
Bayesian modelling allows radiocarbon data to be analysed along with relative archaeological information “prior information”, e. This can :.

By Kellie Chudzinski For Dailymail. She first started modeling at just 15 and signed to an agency the following year. The year-old model took fans down memory lane Tuesday night, as she shared the first polaroids that were taken of her in The then teenager posed for the shots after signing to Model Management at just Over a set of young fresh-faced photos she wrote: ‘Just came across these – the first polaroids ever taken of me back in in London at my first agency.
In the photos she wore a baby blue tank, and had her blonde hair swept back into a messy bun showing off her bone structure. The UK born beauty shared a second set of polaroids in different outfits, apart of another modeling profile. In those she wore a black, long-sleeve tee and left her shiny hair down near her face. For a third outfit, she wore a blue graphic tee, a denim mini skirt and black sheer tights. After signing to her first agency she quickly shot for Teen Vogue and made her catwalk debut at just 17 alongside Naomi Campbell.

Radioactive material gets a bad rap, what with radiation and fallout and nuclear waste and all. But it offers some practical uses. One of the coolest OK, maybe the coolest is using radioactive carbon to determine the age of old bones or plants. To understand this, you must first understand radioactivity and decay. When an element undergoes radioactive decay, it creates radiation and turns into some other element.
Of course, the best way to understand something is to model it, because the last thing you want to do at home is experiment with something radioactive. Here are two ways to model radioactive decay. Before doing any modeling, you must first understand one key idea: Each atom in a sample of material has an essentially random chance to decay.
The rate of decay depends upon the number of atoms you have. This means that as more of these atoms decay you have a lower rate of radioactive decay.

First, we describe numerical models of two geomorphic processes, moraine degradation and inheritance, and their effects on cosmogenic exposure dating.
Models is a book on becoming an attractive man based not on tricks, tactics, games or techniques, but on self-development. So I was more than pleasantly surprised to discover that Models goes well beyond what he discusses on his blog. In my mind though, the most important aspect of this book is the mindsets and attitudes he advocates. What Mark understands is that meaningful encounters and relationships, from a one night stand to a lifelong partnership, are best achieved by seeing male to female relations as mutually beneficial.
In his eyes, dating is a game to be played by men and women who want to give each other amazing and fulfilling experiences, as well achieving this themselves. Models is, without a doubt in my mind, a necessity for the modern man. The insight you have, not just about women but life in general is amazing. It had quite a lot of insight. It really resonated with me because it reaffirmed much of my experience with men whos characteristics I really look up to.
I hope all is well on your end and that life in Columbia is treating you well. Actually, the night we went out there were two of us students , myself and my friend Dave. Last week I was out with a friend of mine at a bar, and I happened to meet a girl there.
