You’ve got a presentation coming up in two months.

7 Strategies That Make Speechwriting Easier

What do you do: Get cracking on writing that speech immediately, or put it off until closer to the date? Most of us will choose the latter. You’ve got time after all. That is, until 2-months turns into a month. And that month turns into a week. What’s the reason behind so many people putting off preparation? I posed a related question to my network: What’s the hardest part of writing your speech? The results of this informal poll revealed that the biggest block to writing a speech is (drumroll please)… Starting. Apparently, it’s more fun to scrub a toilet than to write your presentation. Let’s make it a whole lot easier to get your speech started! 1. When you have a presentation to give, the first inclination is fire up your laptop, open PowerPoint and start typing away. Step away from the computer. Having a strategy in place first makes it so much easier to write your speech. 2.

Régression linéaire. Un article de Wikipédia, l'encyclopédie libre.

Régression linéaire

Formellement, on modélise la relation entre une variable aléatoire y et un vecteur de variables aléatoires x. De manière générale, le modèle linéaire peut s'écrire de la manière suivante : Le terme y désigne la variable expliquée. Le vecteur x désigne l'ensemble des variables explicatives : . On suppose qu'on dispose de données sur les variables . Des paramètres : On parle aussi de modèle linéaire ou de modèle de régression linéaire.

En général, le modèle de régression linéaire désigne un modèle dans lequel l'espérance conditionnelle de y sachant x est une transformation affine de x. Le modèle de régression linéaire est souvent estimé par la méthode des moindres carrés mais il existe aussi de nombreuses autres méthodes pour estimer ce modèle. Bien qu'ils soient souvent présentés ensemble, le modèle linéaire et la méthode des moindres carrés ne désignent pas la même chose.

Smart Grid Marco on CEP. Please contribute to: Event Processing Wiki SAP Business Insight Can't find much info about this one, apart from high level marketing info here WestGlobal Vantify WestGlobal provides Vantify, a product for medium to large enterprises requiring real-time Business Activity Monitoring and Business Transaction Monitoring.

Marco on CEP

Vantify uses CEP technology to detect anomalies in the behaviour of processes and underlying software services, and proactively alerts Business and Technical Operations before customers are impacted. Progress Apama Progress Apama uses a rule based approach to processing event streams. StreamBase StreamBase uses a similar approach as Coral8. SQLstream Streaming data processing tool. RuleCore CEP Server Location Aware CEP Rules RuleCore is a system building block designed to add CEP to an Enterprise Architecture where location aware CEP rules are required. Uses a modular, extensible and open XML based configuration language.

WebSphere Business Events (WBE) Tibco BusinessEvents Truviso. Software transactional memory. Performance[edit] The benefit of this optimistic approach is increased concurrency: no thread needs to wait for access to a resource, and different threads can safely and simultaneously modify disjoint parts of a data structure that would normally be protected under the same lock.

Software transactional memory

However, in practice STM systems also suffer a performance hit compared to fine-grained lock-based systems on small numbers of processors (1 to 4 depending on the application). This is due primarily to the overhead associated with maintaining the log and the time spent committing transactions. Even in this case performance is typically no worse than twice as slow.[5] Advocates of STM believe this penalty is justified by the conceptual benefits of STM[citation needed]. Theoretically, the worst case space and time complexity of n concurrent transactions is O(n). Conceptual advantages and disadvantages[edit] Composable operations[edit] This scheme has been implemented in the Glasgow Haskell Compiler. C/C++[edit]
