Yahoo! LifeStyles: British Gas Smart Meter

Suddenly you're out of control, lashing out with your words or even fists. It's a situation that causes problems for most of us at some point; but loss of temper can end relationships and careers. Some people are genuinely scared of their inability to control their temper. New father Barry admits: "I have gone so far as to strike at my wife, although I never actually hit her. But I knocked a hole in my door right by her head… I am scared I scare my family. " And the internet is full of sad stories like his. Why Log Returns « Quantivity. A reader recently asked an important question, one which often puzzles those new to quantitative finance (especially those coming from technical analysis, which relies upon price pattern analysis): Why use the logarithm of returns, rather than price or raw returns?

Why Log Returns « Quantivity

The answer is several fold, each of whose individual importance varies by problem domain. Does Java pass by reference or pass by value? Q: If Java uses the pass-by reference, why won't a swap function work?

Does Java pass by reference or pass by value?

A: Java does manipulate objects by reference, and all object variables are references. However, Java doesn't pass method arguments by reference; it passes them by value. Take the badSwap() method for example: public void badSwap(int var1, int var2){ int temp = var1; var1 = var2; var2 = temp;} When badSwap() returns, the variables passed as arguments will still hold their original values. If we execute this main() method, we see the following output: 5 unnecessary insurance policies. Risk management is the basis of insurance.

5 unnecessary insurance policies

Fear of the uncertain future creates the need for financial protection against a catastrophe. However, I recently stumbled on an article that provides reasons why some types of insurance are unnecessary. Here are the five unnecessary insurance policies mentioned: 1. 10 Things You Should Never Say to Your Boss. Saying the wrong thing to your boss can really damage your career.

10 Things You Should Never Say to Your Boss

From refusing to work with a colleague to bragging about your irreplaceability, here are 10 things you never want to say to your manager: 1. "Can you write that down for me? " When you're talking about the details of a project, writing notes to consult later is great. But you need to take them yourself, not ask your boss to do it for you. 2. 3. 4. 5. 6. 7. 8. 9.

Most people avoid it by generally doing good work and keeping complaints about their jobs to themselves or close family. Unfortunately, it's not that simple. Math Doctor Bob. Positive Semidefinite Matrix. Convex is complex. Convex or concave?

Convex is complex

It's a question we usually answer just by looking at something. It's convex if it bulges outwards and concave if it bulges inwards. But when it comes to mathematical functions, things aren't that simple. A team of computer scientists from the Massachusetts Institute of Technology have recently shown that deciding whether a mathematical function is convex can be very hard. Top 5 tips To Clear Your Head. A short break in between tasks will make you more productive Sometimes you can have days or even weeks when you have so much on your mind that you're never quite able to get focused.

Top 5 tips To Clear Your Head

It's at times like these that you'll need to do some serious decluttering! Decluttering your mind is about clearing your head so you can focus more on the important things. Aside from making a list and trying to get organized, here are tips to help you clear your mind of any 'excess baggage', so that you will be able to focus more on the things that are of the greatest importance. 1. 2.

Benjamin Graham formula. Note that Graham never intended this formula to be used to evaluate stocks.[2] Formula calculation[edit] In The Intelligent Investor, Benjamin Graham describes a formula he used to value stocks.

Benjamin Graham formula

He disregarded complicated calculations and kept his formula simple. In his words: "Our study of the various methods has led us to suggest a foreshortened and quite simple formula for the evaluation of growth stocks, which is intended to produce figures fairly close to those resulting from the more refined mathematical calculations. " Moving Averages: What Are They? By Casey Murphy, Senior Analyst ChartAdvisor.com Among the most popular technical indicators, moving averages are used to gauge the direction of the current trend. Every type of moving average (commonly written in this tutorial as MA) is a mathematical result that is calculated by averaging a number of past data points. Once determined, the resulting average is then plotted onto a chart in order to allow traders to look at smoothed data rather than focusing on the day-to-day price fluctuations that are inherent in all financial markets.

Constraint algorithm. In physical chemistry, a constraint algorithm is a computational method for satisfying constraints for bodies that obey Newton's equations of motion. There are three basic approaches to satisfying such constraints: choosing novel unconstrained coordinates ("internal coordinates"), introducing explicit constraint forces, and minimizing constraint forces implicitly by the technique of Lagrange multipliers or projection methods.

Constraint algorithms are often applied to molecular dynamics simulations. Although such simulations are sometimes carried out in internal coordinates that automatically satisfy the bond-length and bond-angle constraints, they may also be carried out with explicit or implicit constraint forces for the bond lengths and bond angles. Explicit constraint forces typically shorten the time-step significantly, making the simulation less efficient computationally; in other words, more computer power is required to compute a trajectory of a given length. Where and . Then. NBCTK: Naive Bayes Clustering Toolkit. ModelAssist for ModelRisk. Verlet integration. Verlet integration (French pronunciation: ​[vɛʁˈlɛ]) is a numerical method used to integrate Newton's equations of motion.[1] It is frequently used to calculate trajectories of particles in molecular dynamics simulations and computer graphics.

The algorithm was first used in 1791 by Delambre, and has been rediscovered many times since then, most recently by Loup Verlet in 1960s for molecular dynamics. It was also used by Cowell and Crommelin in 1909 to compute the orbit of Halley's Comet, and by Carl Størmer in 1907 to study the motion of electrical particles in a magnetic field. The Verlet integrator offers greater stability, as well as other properties that are important in physical systems such as time-reversibility and preservation of the symplectic form on phase space, at no significant additional cost over the simple Euler method. Basic Störmer–Verlet[edit] For a differential equation of second order of the type with initial conditions and , an approximate numerical solution. Constraint algorithm.
