SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions.
documentation for optimal filtering toolbox for mathematical software
package Matlab. The methods in the toolbox include Kalman filter, extended Kalman filter
and unscented Kalman filter for discrete time state space models. Also included in the toolbox
are the Rauch-Tung-Striebel and Forward-Backward smoother counter-parts for each filter, which
can be used to smooth the previous state estimates, after obtaining new measurements. The usage
and function of each method are illustrated with five demonstrations problems.

Main program running when workpiece is ready on deferent belt(deferent_ready=ture).
* Call Square_Wave subroutine to generate 0.5ms square wave on P1.2 to drive
* electromotor,then drive deferent belt step forward. When it steps to the measure
* zone, it stops to be measured. Then call A_D subroutine to transform analog
* signals to digital signals , after then call serial subroutine to transfer
* digital signals to PC. Call square wave subroutine to drive deferent belt step to
* original position waitting for defere ready flag to run the next circle.
Parallel robotic manipulators can be considered a well-established option
for many different applications of manipulation, machining, guiding,
testing, control, tracking, haptic force feed-back, etc. A typical parallel robotic
manipulator (PM) consists of a mobile platform connected to the
base (fixed platform) by at least two kinematic chains called limbs. The
mobile platform can achieve between one and three independent translations
(T) and one to three independent rotations (R).
Program helping you to remember the route.
It cab be route from conference room to coffee-room, it can be tourist trip, it can be pathway in labyrinth. during first traversal you make notes in you phone, specifying direction of movement and target of each step. Phone remembers how much time each steps takes. Then you can just inspect information about this trip and check duration of each stage and the whole trip. You can also replay it in forward and backward direction. So if somebody show you the shortest way to coffee machine, you can easily find the way back and can repeat this trip in future.
A routing scheme for content based networking. Content-based network is a network which does nt make use of the source or the destination address to forward a message. This network is quite different from the traditional network.
Licensed spectrum remains 3GPP operators’ top priority to deliver
advanced services and user experience
Opportunistic use of unlicensed spectrum is becoming an important
complement for operators to meet the growing traffic demand
Moving forward 3GPP operators will have two options to offload
traffic to unlicensed spectrum:
1. Wi-Fi (via LTE/Wi-Fi interworking)
2. LTE over unlicensed
It will then be up to each individual operator to choose which
approach to use, which will depend on a number of factors
Relaying techniques, in which a source node communicates to a destination node
with the help of a relay, have been proposed as a cost-effective solution to address
the increasing demand for high data rates and reliable services over the air. As
such, it is crucial to design relay systems that are able to not only provide high
spectral efficiency, but also fully exploit the diversity of the relay channel.
