System and method for a flameless tracer/marker utilizing an electronic light source

An electronic light source system is employed to create a flame-less tracer for a munitions projectile. The electronic light source system may be positioned in various locations and combinations of locations on a projectile (e.g., front, back, side, etc.) to enhance visibility of the projectile during flight. The electronic light source system provides a light source on the projectile that is visible to an observer at various viewing angles throughout the projectile flight without the environmental or safety issues presented by tracers using pyrotechnic materials. After assembly, the present system is encapsulated in glass or clear plastic to G-harden the present system, enabling the present system to sustain the large loads and stresses induced by gun launch. The present system may comprise a variety of light sources such as, for example, lasers, high output light-emitting diodes (LEDs), strobe lights, etc. The present system is capable of flashing the light sources at a variety of frequencies (e.g., 5 Hz, 20 Hz, etc.) to further attract the human eye. In addition, the present system presents the substantial benefit of being able to project light at various wavelengths outside the visible spectrum.

Road network efficiency gain prediction method after breakthrough of broken road

The invention provides a road network efficiency gain prediction method after breakthrough of a broken road. The method comprises the following steps: preprocessing road network vector data; extracting a broken road according to the road network; dividing the road network into a plurality of sub-communities; matching the broken road with the located sub-community; simulating a balance state after flow distribution in the sub-communities before and after a single group of broken roads is opened; according to the balance state of the road network before and after opening, calculating a broken road gain index; and processing the next single group of broken roads until the efficiency gain prediction of the road network after all broken road groups are connected is realized. According to the method, the road network is automatically divided into the sub-communities to calculate the gain after the broken end road is opened, so that the influence caused by the road network scale is avoided; road network nodes which are prone to causing cascade failure are effectively concerned through constraint on OD (Origin-Destination) requirements; and by constraining the gain statistical unit for the road through which the equivalent vehicle passes, the road without flow is prevented from participating in the operation, and the gain of opening the broken road to the road network efficiency can be effectively and reasonably measured.

A method for predicting the efficiency gain of the road network after the broken road is opened up

The invention provides a method for predicting the efficiency gain of a road network after the broken road is opened, which includes preprocessing of the road network vector data; extracting the broken road according to the road network; dividing the road network into several sub-communities; Match the sub-communities; simulate the equilibrium state of the traffic distribution in the sub-community before and after the opening of a single group of dead-end roads; calculate the gain index of the dead-end roads according to the balance state of the road network before and after the opening; The efficiency gain prediction of the road network is achieved until all the dead-end road groups are opened up. The invention automatically divides the road network into sub-communities to calculate the gain after the broken road is opened up, so as to avoid the influence brought by the scale of the road network; and by constraining the OD requirements, effectively pay attention to the road network nodes that are prone to cascading failures; By constraining the gain statistical unit to be the road with the equivalent of vehicles passing through, it avoids the road without traffic to participate in the calculation, and can effectively and reasonably measure the gain of the road network efficiency by opening the dead road.
