Overcome Virtual Network Management Challenges
The virtualized network poses challenges to network management systems -- and as more hardware components become virtualized, that challenge becomes even greater. This handbook discusses the steps IT must take to both build and corral their virtualized infrastructure.

Network devices including switches and routers use a variety of protocols and algorithms to exchange information and to transport data to its intended endpoint. Every endpoint (sometimes called a host) in a network has a unique identifier, often an IP address or a Media Access Control address, that is used to indicate the source or destination of the transmission. Endpoints can include servers, personal computers, phones and many types of network hardware.

Wired and wireless technologies
Networks may use a mix of wired and wireless technologies. Network devices communicate through a wired or wireless transmission medium. In wired networks, this may consist of optical fiber, coaxial cable or copper wires in the form of a twisted pair. Wireless network pathways include computer networks that use wireless data connections for connecting endpoints. These endpoints include broadcast radio, cellular radio, microwave and satellite.

Networks can be private or public. Private networks require the user to obtain permission to gain access. Typically, this is granted either manually by a network administrator or obtained directly by the user via a password or with other credentials. Public networks like the internet do not restrict access.

LANs, WANs, MANs and SANs
Networks may also be categorized by the scope of their domains. Local area networks (LANs) interconnect endpoints in a single domain. Wide area networks interconnect multiple LANs, and metropolitan area networks interconnect computer resources in a geographic area. Storage area networks interconnect storage devices and resources. Networks may also be divided into subnetworks, also called subnets.

The changing role of hardware used in networks in this virtual era
Network protocols and standards specify exactly how data should be transmitted and received. Modern, packet switched networks use protocols -- TCP/IP being the most widespread -- to establish a standard means of communication. The Ethernet standard establishes a common language for wired networks to communicate; the 802.11 standard does the same for wireless LANs.

A network's capacity -- that is, how much traffic it can transmit at any one time -- is measured in terms of bandwidth. Bandwidth is quantified by the theoretical maximum number of bits per second that can pass through a network device. Throughput is a measure of the actual speed of a successful transmission after accounting for factors like latency, processing power and protocol overhead.

Types of computer network topologies
Network topologies represent the physical or logical structure of a network, with common topologies that include the following major types:

Full mesh networks, in which all nodes are connected to each other and can exchange data.
Partial mesh networks, in which some of the nodes are connected to each other in a full mesh scheme, but others are only connected to one or two other nodes in the network.
Point to point networks, which is a connection between only two endpoints.

Network fabric, in which endpoints transfer data to each other through interconnecting switches and can connect to any other by taking a path through a criss-cross pattern of connections.
A tree network, which is a combination of two or more star networks connected together.
A star network, in which the nodes are connected to a common central computer.

A Bus, a circuit arrangement where all network devices are attached directly to a transmission line directly, and while all signals pass through all devices, each device has a unique identity and recognizes signals intended for it.

3D metal printed prototypes
SLA & SLS Rapid Prototypes
SLA & SLS are two of the original 3D printing processes. These methods are ideal for making rapid, one-off prototypes in plastic. These prototypes can be used as-is, or to function as master patterns for polyurethane vacuum casting. Like with other 3D additive manufacturing processes, you can add complex internal features that can’t be made conventionally.

Polyurethane Vacuum Castings

Polyurethane vacuum casting  is a rapid prototyping technique suited for making up to 30 copies of a master pattern from a silicone rubber mold. The level of detail and surface finish of the copies is dependent on the quality of the master pattern. You choose the casting compound to match your design idea – hard or soft, colored or clear. We even offer overmolding to combine two or more different types of material in a single finished casting.

The next two photos are considered reversed polarized (RP-SMA).

We have a team of specialists who are experts at preparing master samples for casting. Samples can be provided by you or we can make them using CNC machining or one of our 3D printing services such as DMLM, SLA or SLS.

You probably know that high-end industrial 3d printers can print metal objects by using laser or electron beams on fine metallic powder but Vader is something completely different. Vader aims at small companies or professional workshop environments by implementing proprietary MagnetoJet Printing (MJP) and magnetohydrodynamic (MHD) ceramic printhead technologies to reduce the machine cost.

It uses molten metal and jets it in small droplets onto a surface similary to a standard inkjet paper printer and by connecting the metal droplets a 3d object can be made. It could be considered world’s first molten metal 3d printer!

Since one of the design ideas behind this machine is to make it widely available, the material it uses had to be widely available and cheap so the main material is molten aluminum wire.

While the basic technology sounds easy in theory and has been used even 20 years ago in the past for some applications, there are still many difficult technical obstacles to overcome. These obstacles include reaching complex requirements like developing a printhead that is resistant to abrasive properties of molten aluminum by using ceramics, magnetic containment and getting drop-on-demand molten metal droplets.

Vader is founded two years ago by Scott and Zachary Vader, a father-son team. With Fall of 2015 being the timeframe for the release of first working pre-production Mark 1 prototype.

The price range of the first machine should be around 250.000 USD which is much cheaper than currently available commercial metal 3d printers.

Hopefully the Vader team will be successful in bringing their machine to the market and start the race for affordable HOME metal 3d printers. I want one! And I know some of you want one too!

Everyone is talking about “the cloud.” But what does it mean.
Business applications are moving to the cloud. It’s not just a fad—the shift from traditional software models to the Internet has steadily gained momentum over the last 10 years. Looking ahead, the next decade of cloud computing promises new ways to collaborate everywhere, through mobile devices.
Life before cloud computing

Traditional business applications have always been very complicated and expensive. The amount and variety of hardware and software required to run them are daunting. You need a whole team of experts to install, configure, test, run, secure, and update them.

When you multiply this effort across dozens or hundreds of apps, it’s easy to see why the biggest companies with the best IT departments aren’t getting the apps they need. Small and mid-sized businesses don’t stand a chance.

Cloud computing: a better way

With cloud computing, you eliminate those headaches because you’re not managing hardware and software—that’s the responsibility of an experienced vendor like salesforce.com. The shared infrastructure means it works like a utility: You only pay for what you need, upgrades are automatic, and scaling up or down is easy.

Cloud-based apps can be up and running in days or weeks, and they cost less. With a cloud app, you just open a browser, log in, customize the app, and start using it.

Businesses are running all kinds of apps in the cloud, like customer relationship management (CRM), HR, accounting, and much more. Some of the world’s largest companies moved their applications to the cloud with salesforce.com after rigorously testing the security and reliability of our infrastructure.

As cloud computing grows in popularity, thousands of companies are simply rebranding their non-cloud products and services as “cloud computing.” Always dig deeper when evaluating cloud offerings and keep in mind that if you have to buy and manage hardware and software, what you’re looking at isn’t really cloud computing but a false cloud.

In the process of 3D Scanning will certainly need a tool that is or better known as 3D laser scanner. The tool works by taking data in the form of points (point cloud) which is also the coordinates of the object or environment is real.

Download Here 3D laser scanner or a 3D scanner is similar to the camera, the angle of view conus (cone three-dimensional). It also collects data from the surface of the object located in front of him. The difference, if the camera collects information such as the surface of the color and intensity of light. While 3D scanners collect distance information from the front of the scanner to the surface of the object being observed. If using a three-dimensional coordinate system are spherical, they can determine the angle variable, and the relative distance from the object surface 3D scanner.

Unlike the 2D scanner that only requires one scanning process, most 3D scanners require repetitive scanning process even up to hundreds, with angles and different sides of the object, in order to obtain complete information on structured in accordance with the reference system used. Once the process is often called the alignment or registration, then the data information collected to be compiled into a data model and intact.

Data collected in the form of points or point cloud, it is usually not directly used. By supporting multiple applications, the data is mostly converted into 3D polygonal objects or polygonal mesh. The converting process is called reconstruction, or better known as reverse engineering.

In the form of 3D models generated from 3D scanning process widely used in the Engineering Design, Manufacturing, Survey Technology, Engineering Construction, Arts, As Built Survey, Oil & Gas Engineering Survey and others. With the 3D scanning process we are easily in the redesign of all forms of objects.
