Abstract: The present invention provides a system and method for measuring an impedance of one or more target cells before and after an electroporation protocol has been applied to the one or more target cells. The result of the impedance measurement provides a feedback control that can be implemented during and/or after the electroporation protocol to customize the electrical treatment for a particular target cell or cellular tissue.

Abstract: Systems are provided to estimate autoregressive moving average (ARMA) models using maximum likelihood estimation and analytical derivatives, and to use such models for forecasting. The evaluation of the analytical derivatives during estimation of the model parameters may be performed using a state space representation with certain characteristics. An ARMA model estimated using maximum likelihood estimation, analytical derivatives, and the state space representation with certain characteristics can be used to forecast/predict values that are likely to occur in the future, given some set of previously-occurring values.

Abstract: A predictive-control approach allows an electricity provider to monitor and proactively manage peak and off-peak residential intra-day electricity usage in an emerging smart energy grid using time-dependent dynamic pricing incentives. The daily load is modeled as time-shifted, but cost-differentiated and substitutable, copies of the continuously-consumed electricity resource, and a consumer-choice prediction model is constructed to forecast the corresponding intra-day shares of total daily load according to this model. This is embedded within an optimization framework for managing the daily electricity usage. A series of transformations are employed, including the reformulation-linearization technique (RLT) to obtain a Mixed-Integer Programming (MIP) model representation of the resulting nonlinear optimization problem. In addition, various regulatory and pricing constraints are incorporated in conjunction with the specified profit and capacity utilization objectives.

Abstract: A seismic gun system for surveying underground geological topology, the seismic gun system comprising a projectile, a seismic gun body, a barrel, and a guide tube. The projectile includes an outer tubular jacket and a frangible material in its interior. A exterior surface of the tubular jacket is textured to regulate tubular jacket disruption. The barrel includes a breach end and a muzzle end. The breach end is connectable to the seismic gun body for receiving the projectile into said barrel and said muzzle end directing the projectile towards the bottom of a bore hole. The guide tube has an upper end and a terminal end. The upper end of the guide tube is connectable to the muzzle end of the barrel. The guide tube has walls to direct the projectile towards the bottom of the bore hole when aimed therein.

Abstract: A seismic gun assembly comprising a barrel and guide tube assembly for delivering a projectile to the bottom of a bore hole with a non-line-of-sight section. The guide tube being either a large diameter guide tube or a tight fitted guide tube. The large diameter guide tube allowing the projectile to perform shallow angle bounces to reach the bottom of a non-line-of-sight bore hole. The tight fitted guide tube allows the projectile to ride the inner wall of the guide tube to reach the bottom of a non-line-of-sight bore hole. The projectile comprises an outer jacket and a frangible core. The seismic gun barrel assembly additionally comprises a fluid exclusion puck for preventing fluids from entering the guide tube, a suppressing collar for suppressing seismic noise, and a method for modulating recoil.

Abstract: An apparatus for processing articles moving in succession along a path includes a conveyor device, a splitter device and a weighing device. The conveyor device is arranged to convey a succession of individual articles from and along a single upstream path to and along a first split downstream path and a second split downstream path. The splitter device splits the succession of articles onto the first and second split downstream paths. Also, the splitter device directs alternate ones of the succession articles being conveyed on the single upstream path onto the respective first and second split downstream paths. The weighing device weighs each article while the articles are conveyed along the first and second split downstream paths.

Abstract: A method and apparatus is provided for monitoring the processing of a group of articles having different properties, for example differing weights and/or quality grades. The method includes the steps of obtaining information about the differing properties of the group, using this information to provide a main visual model of the property distribution within the group, and providing a first subsidiary visual model relating to the processing of a first sub-group of articles from within the group, the provision of the first subsidiary model causing a modified form of the main visual model to appear, related to the remaining articles of the group after removal of the articles forming the first sub-group. The method is particularly effective for use in monitoring the processing of poultry carcasses being conveyed in succession along a path, for sorting by weight and grade of carcass.

Abstract: Processes for coating a ferrous or aluminum article, such as an engine cylinder liner insert, to provide a metallurgical bond with aluminum alloy material cast around the article. The article surface to be bonded is treated to remove impurities, oxides, and foreign materials, and the article is preheated. A molten metallic bonding material, such as zinc or a zinc alloy, is provided and the treated and preheated article is immersed in the bonding material to provide a metallurgically bonded coating on the surface of the article being treated. The coated article, either shortly after coating or, alternatively, after having been cooled to ambient temperature and stored, can then be placed in a mold and molten aluminum alloy poured around it to metallurgically bond the aluminum to the coating on the article. The resulting structure provides a metallurgical bond that has improved heat transfer characteristics and improved structural integrity.

Abstract: The invention discloses a weight sorting system wherein a single weighing station controls a plurality of weight-range article removal stations. These removal stations are disposed downstream of the weighing station and sorting information is synchronously passed with the articles on route to discharge. The rate at which articles are selected for removal at a given station is controlled by varying the weight range for that station. The weighing system is constantly re-calibrated by employing a plurality of test weights, one for each sorting weight range, carried by the conveyor system and an electronic compensating unit.

Abstract: Grading apparatus is provided for use in associating one of a plurality of a grade with each of a plurality of articles travelling in succession along a feed path. The apparatus comprises a grading station of sufficient length to accommodate at least two articles at any one time, a control unit, and at least two means of feeding a grading signal to the control unit. Although the same amount of work is involved it is easier for an operator to grade say four articles at a time over a distance of say 2 feet, rather than to grade one article at a time over a distance of 6 inches.

Abstract: A sensing device is provided which increases the versatility of sorting and conveying systems employing the device while simplifying their construction.
