An assessment method is defined as the philosophical or pedagogical approach to assessing. For example, written assessment or practical assessment, formative or summative assessment. Assessment tools are used for different assessment methods and are more specific.

Method and system for evaluating network safety situation

The invention relates to a method for evaluating the security situation of a network and a system thereof. The system has a two-surface three-level framework and is provided with a public service surface and a service management surface for executing uniform coordinated management on each functional module of the system; according to a service logic processing flow, the system is divided into three levels: an acquisition level, an analysis level and an exhibition level for completing four evaluating operations of assets, frangibility, threat and security situation; the invention is based on the characteristic of service operation in the network, combines the prior risk evaluation method, the prior flow and the prior security detection tool and provides a set of a novel dynamic real-time evaluation method. The system can analyze the assets and service of the network and the risk of the whole network and carries out the evaluation of the security situation. The system can provide the security state of the whole network in macroscopy, can deepen to specific service and assets and know the specific security problem, thereby effectively helping network security personnel to analyze the root of the security problem and assisting to provide a security solution proposal and implement a defense measure.

Error coding in asynchronous transfer mode, internet and satellites

The transmission of ATM, Internet, and satellite communications is unified through international standardized protocol embedment. Global and Local performance optimization are achieved through the combination of combinatorial, dynamic, and probabilistic programming. A simultaneous domino effect of bandwidth conservation, efficiency enhancement, reliability improvement, traffic congestion prevention, delay minimization, and speed multiplication are realized for any digital communication system, particular in Internet. With three levels of error coding in ATM cells, the loss cell recovery and bit integrity are preserved. From its mathematical roots, new combinatorial sets are systematically generated, and applications of the sets are identified. Among the applications, optimal sequences can be produced for multi-user and multi-function communication system designs. Optimality is in terms of maximum possible number of sequences with given sequence length and sequence characteristics. The results are unique and theoretically proven. By serial and parallel concatenation of error codecs, reliability of multimedia transmission can be satisfied to any desirable level. As a part of the unified transmission scheme, the acquisition and synchronization method of cascading sequences exhibits significant improvement in correlation properties and detection probabilities. A method of using block designs is demonstrated to derive, to generate, and to construct low-density parity check block codes and threshold decodable convolutional codes. An efficiency evaluation method is formulated for the combination operation of ATM, Internet, and satellites.

System and method for implementing electronic markets

An efficient system for implementing an electronic market. The system includes a first mechanism for defining a set of attributes and associated descriptor variables involved in market transactions. Importance values are assigned to the descriptor variables by the first mechanism. A second mechanism computes match scores for the market transactions based on the importance values. A third mechanism employs the match scores to clear the electronic market. In the specific embodiment, the first mechanism includes an administrator interface, which allows an administrator to define the descriptor variables. A configurator communicates with the administrator interface and allows the administrator to assign a first set importance values to corresponding descriptor variables. The first set importance values includes default importance values or importance values assigned to the descriptor variables by a seller seeking to transact with a buyer via the electronic market. The administrator interface allows an administrator to configure a user interface of the market to allow market participants to assign a second set of importance values to different descriptor variables. The second set of importance values includes buyer and seller importance values. The descriptor variables and associated descriptor importance values may be continuous or discrete. A matching engine computes the match scores for market transactions based on a predetermined evaluation method specified via the administrator interface and based on a unique match score computation method.
