A system and method may be used to track software changes by analyzing intermediate language level representations of the software. For example, software changes may be tracked by analyzing object-oriented program code that includes one or more non-native binary executables based on an intermediate language. The program code may be associated with metadata describing content of the non-native binary executables. An object tree, which includes a plurality of nodes, may be constructed to represent the non-native binary executables and the metadata describing the content of the non-native binary executables. One or more of the plurality of nodes may be hashed to associate respective digest values with the hashed nodes, such that changes in the received program code can be tracked using the digest values associated with the hashed nodes.

An illumination system includes multiple light emitting devices arranged in an area so as to be spaced apart from each other. Each light emitting device includes multiple light emitting diode arrays each of which has one light emitting diode or a plurality of light emitting diodes connected in series. The numbers of the light emitting diodes included in each light emitting diode arrays differs from each other. A controller is configured to establish one or more groups each including one or more light emitting devices and adjust an illumination state of each light emitting device by controlling the driving state of the one or more light emitting diode arrays included in each light emitting device. The controller may select the number of light emitting devices included in each group based on an external condition.

A disc filtration system comprises a filter element containing microporous plastic discs through which liquid effluent such as wastewater is passed for filtration. The filter disc surface material contains an anti-bacterial agent exposed to the liquid being filtered for inhibiting growth of microorganisms on the exterior of the filter element. The exposure to the anti-bacterial agent inhibits microorganism growth to an extent that prolongs the useful operational filtration cycle life of the filter between backwashing cycles. The invention applies to disc filters having automatic backwashing and manually operated disc-type filters.

A method and software product for controlling a percussion device belonging to a rock-drilling machine, and a percussion device. The impact frequency of the percussion device is set so that the percussion device forms a new compression stress wave to the tool always when reflected waves from the previous compression stress waves reach a first end of the tool. This requires that the impact frequency be set proportional to the propagation time of the stress wave, whereby the length of the used tool and the propagation velocity of the stress wave in the tool material are to be noted.

The invention provides fertilizer special for reducing cadmium in soil and a preparation method of the fertilizer. Main components of the fertilizer comprise expanded vermiculite powder, vinasse, animal manure, straws, chicken manure, microorganisms and plant ash. The alkaline fertilizer plant ash has a certain passivation effect on cadmium; by the adoption of mutual cooperation of flora such as black aspergilus and saccharomycetes in the vinasse, the fertilizer has a very good cadmium passivation effect; the added expanded vermiculite powder has a certain slow release effect on microbial flora, can prolong the effective time of the fertilizer and also has a certain adsorption effect on the cadmium. The fertilizer and the preparation method of the fertilizer can greatly reduce the content of effective cadmium in the soil and reduce cadmium absorption of plants so as to achieve the effect of reducing the cadmium in the soil.

By adopting the method, the device and the base station, a circumstance that the MTC terminal mistakenly judges that the system message is not changed can be avoided, and the power consumption, which is caused by frequently reading unmodified system messages, of the MTC terminal is reduced.

Accurate long term satellite models for satellites include satellites of different navigation systems. Such a model is derived for a non-GPS satellite that broadcasts native orbital model data specified as valid within a first time period. Initial position and velocity data are determined from the native orbital model data, and orbit integration is performed to determine an orbital arc in an earth-centered-earth-fixed frame over a second time period longer than the first time period. Initial estimates of GPS or GPS-like orbit parameters are determined for the non-GPS satellite, and the orbital arc and the initial estimates of the GPS or GPS-like orbit parameters are input to an orbit parameter solver that determines GPS or GPS-like parameters that fit the orbital arc and is used to determine final orbital model parameters in GPS or GPS-like format for the non-GPS satellite.

The invention discloses a fish oil enteric coated microcapsule and a preparing method thereof. The enteric coated microcapsule is mainly prepared from raw materials of 200-400 parts of fish oil 200-400 parts of lecithin, 100-200 parts of glycerinum, 2-5 parts of natural vitamin E, 1-2 parts of lemon oil, 100-200 parts of sodium alginate and 1000-1300 parts of calcium amino acid chelate. The sodium alginate and the lecithin have an emulsifying effect, the glycerinum has an emulsification assisting effect, and the fish oil is emulsified by the sodium alginate, the lecithin and the glycerinum. When the sodium alginate substitutes with calcium ion in calcium water solution, calcium alginate which does not dissolve in water is formed to wrap the fish oil to form the enteric coated microcapsule, and then the enteric coated microcapsule is filled into a hard capsule. Thus, no fishy smell goes out the stomach reversely. Furthermore, the fish oil enteric coated microcapsule is easy to absorb, high in stability and long in valid period.
