Abstract: Disclosed are various embodiments for providing an efficient and time-saving shopping experience by allowing a user to initiate a purchase of items corresponding to items included in an item list (e.g., shopping list) while minimizing user interactions. A user may initiate a shopping experience via a voice command and/or an interaction with a user interface associated with a list management service. Using keywords included in the item list, a list of recommended items that correspond to items included in the shopping list and are available for purchase at a particular store can be determined and presented to the user. Item listings may be preselected for purchase based at least in part on a determined likelihood that the user will purchase the item. The user can review the recommended items and select a purchase component (e.g., add-to-cart component, buy component), that upon selection, initiates the purchase of the selected items.

Abstract: This disclosure relates to a method and system for real time prediction of tire remaining useful life using a tire digital twin. Herein, the digital twin of the tire monitors a plurality of tires while accounting for runtime as well as parking operation of tires. During runtime, tire goes through multiple operational changes, therefore, the system is configured to estimate the operational changes. The estimation is done in the form of index, which is compared with the manufacturers' recommended value. Similarly, while vehicle is parked, tire still goes through changes which play an important role in its overall health, like, long pending wheel rotation can lead to flat spot. Tire inflation can change owing to cool down effect as well as uncontrolled natural leakages. Further, these parameter indexes are clubbed together to calculate the health index of the tire, which is used to estimate the tire's current remaining useful life.

Abstract: Rotary knifes/cutters play an important role in manufacturing of finished products. The rotary cutters tend to lose their cutting material over time. Hence to compensate, pressure applied by cylinder over rotary cutter needs to be changed. But this change in pressure needs to be optimum as too high pressure can lead to loss of material and too low pressure can stop cutting operation. Present application provides methods and systems for real time estimation of pressure change requirements for rotary cutters. The system first determines minimum and maximum usage limit for rotary cutter based on historical rotary cutter usage data and real-time pressure value using first trained model. The system, upon determining that minimum usage limit is reached, determines time for next pressure change based on physical parameters using second trained model. Thereafter, system compares estimated time with estimated maximum usage limit and displays notification to change pressure based on comparison.

Abstract: Combined cycle gas turbine (CCGT) power plants have become common for generation of electric power due to their high efficiencies. There are various problem related with improving the efficiency of CCGT plants by optimizing the manipulated variables. The method and system for optimizing the operation of a combined cycle gas turbine has been provided. The system is configured to calculate an optimal value of manipulated variables (MV) with efficiency as one of the key performance parameters (KPI). The MVs from the existing CCGT automation system, i.e. a first set of manipulated variables and the manipulated variables from the optimization approach, i.e. a second set of manipulated variables are combined to determine an optimal set of manipulated variables. The method further checks for the anomalous behavior of the system and define the root cause of the identified anomaly and the operational state of the CCGT plant.

Abstract: Disclosed herein is a method and system for establishing secure communication between a terminal device and a target system. The method comprises validating the terminal device and the target system based on a communication request received from the terminal device. Upon validation, the terminal device is signaled to generate a Quick Response (QR) code corresponding to the communication request. Subsequently, the QR code generated at the terminal device is processed using a predetermined verification interface configured in a user device for establishing the secure communication between the terminal device and the target system. In an embodiment, the present disclosure helps users in completing a transaction based on the QR code generated at the terminal device, and thereby eliminates requirement of using a credit card/debit card and the like for completing the transaction.

Abstract: The efficient operation of an electric vehicle depends greatly on proper functioning of a battery pack in the electric vehicle. A system and method for optimizing the operation of the battery pack in an electric vehicle is provided. The system comprises a digital twin for a battery pack in an electric vehicle. The system determines the state of charge, state of health and temperature distribution in the battery pack using various models. This information can be used to predict optimal charge and discharge profiles of the battery pack for given load conditions, as well as remaining useful life of the battery. The digital twin would require inputs such as battery temperatures from the sensors, coolant flow rates, coolant temperature, ambient temperature, load on the vehicle, current and voltages from the pack and battery characteristics from the manufacturer.

Abstract: Performance and lifespan of batteries deteriorate with time due to various factors. Existing systems for battery management use different approaches for the battery management, and also rely on static value of parameters for State of Health (SOH) and Remaining Useful Life (RUL) estimation, thereby failing to consider current condition of the battery. The disclosure herein generally relates to battery management, and, more particularly, to a method and system for online battery management involving real-time estimation of State of Health (SOH) and Remaining Useful Life (RUL) of a battery, based on real-time data collected from the battery. The system determines state of the battery as one of charging, discharging, and rest. Further, corresponding to the determined state, the system determines values of one or more parameters, and processes the determined values with a battery performance model for online determination of the SOH and RUL.

Abstract: A messaging system provides messaging interactions between users of a group. A message received from a subscriber user and intended for an administrator user is routed to an administrator user, the message not being visible to other subscriber users. A message received from an administrator user and intended for a specific subscriber user is routed to the specific subscriber user, the message not being visible to other subscriber users. A message received from an administrator user and intended for plural subscriber users is routed to the plural subscriber users. A subscriber user is unable to send a message to another subscriber user via the messaging system.

Abstract: A server, user terminal, system, method and computer-program product for performing a data transfer to upload a data file from the user terminal to the server or download a data file from the server to the user terminal, via a connection over a network. The method comprises evaluating a size of the data file to be uploaded or downloaded, determining a measure of a current workload of the server, and estimating a bandwidth of at least part of the connection. A time-out window is derived during which the transfer of the data file is allowed to be performed, wherein the deriving of the time out window is performed based the data file size, server workload and bandwidth. The data transfer is enabled during the time-out window, but timed out when the time-out window expires.

Abstract: A system and method for aggregating user response data in a communication system such as an instant messaging (IM system). Aggregation is performed according to a hierarchical group addressing structure into which users are arranged. Data may be input, output and distributed in a structured data format. Aggregating information comprises collating, in each group in the hierarchical group addressing structure, information contained in responses from individual users in that group. Aggregating said information may further comprise collating, for each group in the hierarchical group addressing structure, information contained in responses from all child groups subordinate to that group. Because the grouping structure for addressing or routing is pre-existing, no additional grouping or categorising of individuals or responses is required.
