A solution set is generated, and solutions in the solution set are evaluated. Desirable solutions from the solution set are selected. A structural model is created using the desirable solutions, and a surrogate fitness model is created based on the structural model and the desirable solutions. A new solution set may be generated and/or evaluated, based on analyzing at least one of the structural model and the surrogate fitness model, and determining a method for generating a new solution set and/or evaluating the new solution set based at least in part on the analyzing.

Received plaintext is encrypted using the cascaded chaotic maps to generate a ciphertext. The ciphertext can then be decrypted using the same cascaded chaotic maps in order to retrieve the plaintext.

When a triggering access is detected, a function is accessed for determining a monitoring function, and a monitoring function associated with a particular triggered memory location address is automatically determined.

While a previously... Read More In the present scalable system routing method, received packets are associating with threads for processing the received packets. While a previously received packet is being processed, arrival of an interrupt is checked. If there is an interrupt, a thread is created associating the interrupt is created. Then, a determination of whether the thread associated with the interrupt has a priority that is higher than the priority of a thread associated with the previously received packet is made. If the thread associated with the interrupt has a higher priority than the previously received packet, the thread associated with the previously received packet is saved in a Shared Arena storage area. However, if the thread associated with the interrupt does not have a higher priority than the previously received packet, the thread associated with the interrupt is queued. Because threads are attached to the packets, the threads can now be suspended and resumed without having to disable interrupts, which includes periods during a context switch. As a result, a more flexible and efficient scheduling routing method can be implemented.
Method for Allocating Multiple Authentication Certificates to Vehicles in a Vehicle -to-Vehicle Communication Network In a vehicle-to-vehicle communication network utilizing PKI security methods to protect communications and in which the PKI encryption utilizes a... Read More In a vehicle-to-vehicle communication network utilizing PKI security methods to protect communications and in which the PKI encryption utilizes a Certificate Authority having both a private key and a publicly distributed key, a method for allocating multiple certificates for each vehicle which are assigned to each vehicle in the communication network. The method includes the step of assigning a unique secret key k to each vehicle in the communication network. The Certificate Authority then creates a plurality of public key and private key encryption pairs for each vehicle and each encryption pair is associated with an index i. A plurality of certificates are then created with one certificate for each value of the index. A revocation list comprising the secret keys is maintained by the Certificate Authority so that all encryption pairs assigned to a particular vehicle may be revoked by the secret key k corresponding to that vehicle.

Read More Dr. Paul Selvin from the University of IL has developed a streamlined process for creating coverslips with built-in, nanoscale fiduciary markers using thermal NIL. Unlike 50‐100 nm fluorescent nanoparticles, these markers can be custom made to different sizes and shapes. Using this method, Dr. Selvin found that there is no resulting auto-fluorescence in the blue part of the spectrum (emission from 450 nm and farther red), allowing for more proteins to be tracked simultaneously, a major advantage in the field. Additionally, the coverslip is stable enough to culture primary neuronal cells for over 2 weeks, while other micropatterned coverslips would detach from the glass surface during that amount of time.
