Virtual Reality Up Close

cat January 17th, 2011 by Virtual Keeper

Since the advent of high speed computers and fabulous graphics, virtual reality became a force to contend with.  But what is virtual reality? Basically, virtual reality means computer-simulated environments. The user feels as if he is in an actual place, doing actual tasks, when in real-reality he is just sitting in front of a computer screen. This idea was highly popularized in the hit movie Matrix, where an entire population was hooked up to a giant computer and made to believe they were living their lives, when the truth was they were donating their electricity to power the machines that had taken over the world.

There are many uses today for virtual reality, aside from making interesting and complex film plots. The vast majority of virtual reality experiences rely primarily on the visual sense, and to a certain extent the sense of hearing. The scene is broadcast to the user via a computer screen, or special glasses. There are some virtual reality experiences that do incorporate other senses. Multimodal devices, such as a wired glove or treadmills which are omnidirectional can enhance the virtual reality experience by encompassing more of the sensory input of the user.

What Are Access Controls

cat February 22nd, 2017 by Virtual Keeper

Access controls are those security systems whose function is to determine who can use what, managing resources, users and permissions according to a series of criteria laid down previously by the system administrator. Access controls are applied in many types of situations, such as physical persons access to facilities, vehicle access to restricted areas, users access to computer systems, control of presence or schedule. Operation of access controls access controls are basically mechanisms which, in function of the identification and authentication of the user, or not authorized access to campuses, data or resources. Access controls play their task in several steps: identification: the user requesting access to the system, which requires some sort of credential that identify you, such as a password, user name, card or fingerprint, that will be subsequently validated the individual or not in the authentication process. Authentication: the system verifies the identity of the user, i.e., checks if the user is who he claims to be, checking the credentials provided by the user in the identification. Financial technology can aid you in your search for knowledge. Authorization: the system checks the permissions of the user and verifies whether it is authorized to access resources requested or to perform functions that aims to. Registration: access controls allow you to know who, what and when accessed, as well as who tries it, so you must save a complete record of all incidents in order to control its activity at all times. Methods of identification and authentication in access controls are used various methods of identification and authentication: systems based on something the user knows: as a password, username or PIN (Personal Identification Number, personal identification number). Jeff Feig New York recognizes the significance of this.

Systems based on something the user has: as a card of identification, smart card (smartcard), barcode or USB device. Systems based on a physical characteristic user: this type of access controls are based on verified biometric patterns such as fingerprints, iris, retinal pattern, facial recognition or DNA recognition. Systems based on something the user does: as voice pattern, writing or signature. Systems based on location and schedule: access controls based on the time, logical or physical location of the person. These systems are not mutually exclusive and usually access controls combine several, for example, a card ID and a PIN. Methods of authorization at the stage of authorization of access controls, the system examines applications for users, and by applying a predefined rules, accept them or reject. To define these rules the system administrator assigns permissions in application of some type of security policies. There are many possible approaches in the security policies, such as MAC, DAC, RBAC, ACL, MLS, all denied, all authorized or least privilege.

The main drawback – the hub breakage leads to the termination of the entire network. Ring topology In the case of ring topology all networked computers connected to a single ring cable. Packets pass around the ring in one direction through all the network adapters connected to the network computers. Each computer will amplify the signal and send it on to ring. In the presented topology, packets transmitted on the ring is organized by the marker. You may wish to learn more. If so, Naveen Selvadurai is the place to go. The marker is a specific sequence of bits containing the control data. If the network device has a marker, then he has the right to send information to the network. Learn more at: Jeff Feig. Inside the ring can be transmitted only one marker.

A computer that is going to carry data, takes the token from the network and sends information requested on a ring. Each next computer will transmit data on until the packet does not reach the addressee. After receiving target return confirmation of receipt of the sender computer and the last creates a new token and returns it to the network advantages of this topology include: more efficient than in the case of a shared bus, operated large amounts of data, each computer is a follower: it amplifies the signal before sending the next machine, which can significantly increase the size of the network, the ability to set different priorities for accessing the network, with a computer that has a higher priority, will be able to delay longer than the token and transmit more information. Disadvantages: Loss of power cable leads to the entire network inoperable; any computer can obtain data that are transmitted over the network.

College of Kumash Nurgalieva – one of the largest schools in the Republic of . Currently, there are trained 2,511 people, including three branches in the cities Ridder, Zyryanovsk and . In college, 20 computer and multimedia classrooms. All computer and administrative offices together into a network that has established a constant electronic connection with its branches. Computers connected to the Internet via leased line with adsl rate of 2048 Kbps. The presence of branches was the main reason for choosing the subject of methodological theme "Development of technology for distance learning and the introduction of ict in the educational process." One method of remote Education – holding video lectures in the mode of op-lipe.

Sometimes it is necessary to organize communication between people at a distance. This approach saves money and time, and video provides a better perception information compared with all other forms of remote communication. The effectiveness of any type of distance learning depends on four components ing: a) the effective interaction between teacher and student, despite the fact that they are physically separated by distance, and b) used in this pedagogical techniques, and c) the effectiveness of the developed teaching materials and methods for their delivery, and d) the effectiveness of feedback. Therefore, when establishment of lectures for distance education should consider the following requirements: 1. Motivation. Motivation – a necessary component of learning, which must be maintained throughout the learning process. 2. Formulation of training objectives. Of great importance is a clearly defined goal, which is placed in front of students.

Laser Marking

Ink jet technology such as the circulation based on the use of liquid ink, which due to its chemical composition can be applied to a wide range of materials. The disadvantage is the added pollution air and the need for cleaning the printer. Some consumers are afraid of chemical analysis used in this technology supplies. 2. Ink jet technology using hot melt ink Dry Touch is used everywhere where cleanliness and environmental security are a prerequisite. Inks are safe and contain no solvents and other hazardous substances.

At room temperature, hot melt ink remain solid, dry and non-marking to use. However, the scope of their application is limited. For example, they are not suitable for non-porous surfaces such as glass. Thermal transfer printers provide high-quality printing. They are good and reliable when applied to different kinds of flexible packaging materials, ensuring the highest accuracy in labeling. By an instantaneous point heat ribbon (thermal transfer ribbon) and the transfer of ink contained in the front side of the ribbon, these printers can print various kinds of information: the date, serial number, manufacturer information, bar codes and real-time printing on individual product packaging. For more information see Peter Thiel.

The main disadvantage, high Printing costs can be overcome thanks to the new function. This ribbon saving function, which makes printers more economically attractive and affordable. A wide variety of mounting hardware allows establish character ink jet markers in different types of conveyors. Equipment adapted to the conditions of high humidity, resistant to shock and vibration and is ideal for any production. Printers differ high reliability, versatility and efficiency in the use of consumables, as well as easily adaptable to the changing speed of the conveyor, can label products at two independent production lines, apply more than 4 lines of text, graphics and a wide range of bar codes, while maintaining clear visibility of characters. Products marked directly on the conveyor or any other technology area. The printer allows you to put on the packaging at least three degrees of protection that is almost beyond the power of the most ingenious forgers. Laser Marking In recent years, due to lower the cost of lasers and increase their share of work, laser marking has become increasingly used in consumer products. The main advantages of laser printers: marked by a wide range of materials (Glass, paper, plastics, metals, ceramics, etc.), the absence of mechanical stress on the product, high resolution, a clear contrast markings; excellent resistance mark during transport, lack of supplies, high accuracy at high speeds. Digital Laser Markers provide a process of labeling under the influence of the laser beam on the surface of the package. This means that there are no costs for consumables. Principle laser treatment is either to remove the paint layer from the surface or in the evaporation or melting of the upper layer of packing material (such as PET, polystyrene, polypropylene). In both cases we obtain indelible instant print quality. Laser printers are a versatile method of labeling the primary packaging due to environmental safety and lack of supplies, as well as through high resolution of the applied code. Until now, the main disadvantages of lasers were high cost and large size. However, modern low-cost compact models are becoming more competitive among the marking equipment.
