History of the Canadian Broadcasting Corporation

As paraphrased from an article written by Rabble news, radio was a new innovation in the 1930s. In Canada, legislators, associations, instructors and numerous others were considering the most ideal approach to sort out this new and dynamic type of correspondence. The nation, and the west, were in monetary unrest from the Great Depression and

Energy Harvesting System inside a 4.7T MRI Scanner

In magnetic resonance imaging (MRI) environment, adding more receiving channels requires a a significant increase in the number of connectors and cables, causing discomfort to the patient. Powering coils or sensor devices inside the MRI scanner could minimize this problem. The challenge here is the ability to recover energy from a 4.7T MRI scanner without

Artificial Neural Network (ANN)

This paper focuses on data-driven hydrological model i.e., Artificial Neural Network (ANN). Performance of ANN models depend on its architecture i.e., patterns of connections between the nodes, weights assigned to each of the connecting nodes, number of layers, activation function and learning rates.

Accounting software in business

It is important to think and put in place an accounting software adapted to the activity of the company even if the company only offers services to their clients. This approach will allow the company to better track transactions and therefore the payment of bills, so it is a saving of time they will have

The evolution of mobile network

Network traffic is handled by both SGSN and GGSN. GPRS network uses its own protocol to encapsulate data. It provides network security and makes data exchange easier. Mobile data and Open System Interconnection (OSI) model OSI model is a network standardization created by International Organization for Standardization (ISO), which is a fundamental concept of the

Implementation of decision support systems (DSS)

One of the single most important benefits of Information Systems (IS) that all businesses wither a large worldwide enterprise or a small family-owned is the ability to work more efficiently and effectively.  With the flexibility of IS enabling reprogramming, this helps with the growth of the company. With most IS having a modular design company

Secteur des télécommunications au Cameroun

Dans ce contexte et à la suite des différents ordres du jour des sociétés de l’information organisés, l’on assiste à une ouverture de la concurrence du secteur des télécommunications au Cameroun qui est consacrée par la loi n° 98/014 du 14 juillet 1998 régissant les télécommunications au Cameroun. Avec cette loi, l’État va se désengager

La data visualisation (DataViz)

La data Visualisation (ou encore DataViz) est la conversion de données brutes, comme les textes et nombres, en représentation visuelles pour permettre la facilitation leur compréhension. Il s’agit d’une transformation de données qui sont difficiles en des représentations visuelles plus simplifiées, ce qui permet la facilitation de la compréhension et de l’exploitation des données. Ainsi,

Qu’est-ce que le data mining?

Le data mining (ou encore exploration de données) regroupe toute une famille d’outils qui facilite l’exploration et qui permet d’analyser des données d’une base décisionnelle tel que Data Warehouse ou DataMart. Différentes techniques efficaces sont mises en place lors de son utilisation. Elles permettent une identification d’informations significatives à partir d’une grande quantité de donnée.

La course à l’espace pendant la guerre froide

La guerre froide Après la seconde guerre mondiale, les deux grandes puissances mondiales, les États-Unis et l\’URSS, se font face dans ce que l\’on appelle la guerre froide. Celle-ci se traduit par des affrontements militaires indirects et une course aux armements, notamment sur le développement de missiles nucléaires intercontinentaux pouvant être capable d\’atteindre le territoire

Forecasting of daily global solar radiation

As solar radiation is the starting point for improving the use of renewable energy. In recent years, several methods have been used to predict daily solar radiation, similar to artificial intelligence and hybrid models. In the present study, a wavelet-coupled Gaussian Process Regression (GPR) (W-GPR) model was adopted to forecast  daily total solar radiation received

Shearing effect in geotechnical engineering

A vast majority of the geotechnical infrastructures (retaining walls, shallow foundations, piles, etc) made of construction material are always surrounded by fine-grained soil. The behaviour of interface shearing between soil and construction material is essential for providing safe and optimal designs within the field of geotechnical engineering. Considerable experimental investigations have been conducted by researchers
