Abnormal crowd behaviour detection by using partical entorpy Abstract? Abnormal crowd behaviour detection by using partical entorpy. We propose a fully unsupervised method for abnormal activity detection in crowded scenes. Neither normal nor abnormal training examples are needed before detection. By observing that in crowded scenes, normal activities are the behaviors performed by the majority…
AC-Plus Scan Methodology for Small Delay Testing and Characterization Abstract? AC-Plus Scan Methodology for Small Delay Testing and Characterization. Small delay defects escaping traditional delay testing could cause a device to malfunction in the field and thus detecting these defects is often necessary. To address this issue, we propose three test modes in a new…
Accelerating MapReduce on Commodity Clusters: An SSD-Empowered Approach Abstract? MapReduce, as a programming model and implementation for processing large data sets on clusters with hundreds or thousands of nodes, has gained wide adoption. In spite of the fact, we found that MapReduce on commodity clusters, which are usually equipped with limited memory and hard-disk drive…
Access Control and Data Updation for Shared Data in Cloud Abstract? Access Control and Data Updation for Shared Data in Cloud. Cloud computing enables data owners to outsource their computationally intensive tasks and store private data to the shared cloud. To enhance the security while preserving the flexibility of data sharing, Attribute Based Encryption (ABE)…
Accident Tracking App For Android Mobile Abstract? GPS location tracking for women welfare android application is a security application which is specially designed for mobile users especially for women. This application offers a helping hand with the help of GPS based location tracing. At the time of emergency there may not be any possibility to…
ACCIDENT TRACKING APP FOR ANDROID MOBILE Abstract? ACCIDENT TRACKING APP FOR ANDROID MOBILE. There are many situations which request a tracking and localization system. Some examples are car/persons tracking and localization in case of accidents or disasters. Due to the hardware and software characteristics of the smartphones, these devices are suitable to work as terminals…
Accuracy-Constrained Privacy-Preserving Access Control Mechanism for Relational Data Accuracy-Constrained Privacy-Preserving Access Control Mechanism for Relational Data. Access control mechanisms protect sensitive information from unauthorized users. However, when sensitive information is shared and a Privacy Protection Mechanism (PPM) is not in place, an authorized user can still compromise the privacy of a person leading to…

Access control mechanisms protect sensitive information from unauthorized users. However, when sensitive information is shared and a Privacy Protection Mechanism (PPM) is not in place, an authorized user can still compromise the privacy of a person leading to…
Accurate Analysis of Double-Weight Codes with an Arbitrary Maximum Cross-Correlation Value for Two-Chip-Power Optical CDMA Abstract? Due to power restriction of some laser sources, the use of same power (per bit duration) in optical codes in incoherent optical code-division multiple-access multimedia networks with variable quality-of-services was previously studied. < Final Year Projects >In those…
Achieving Arbitrary Multiplexing Rates for MIMO-OFDM Systems by Mimo-OFDM Systems by Hybrid Cyclic Delay Diversity Abstract?A new hybrid cyclic delay diversity (HCDD) scheme for multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) systems. Unlike the existing double space time transmit diversity (DSTTD) and stacked cyclic delay diversity (SCDD) schemes that are suitable for…
Achieving Efficient and Secure Data Acquisition for Cloud-supported Internet of Things in Smart Grid Abstract– Cloud-supported Internet of Things (Cloud-IoT) has been broadly deployed in smart grid systems. The IoT front-ends are responsible for data acquisition and status supervision, while the substantial amount of data is stored and managed in the cloud server. Achieving data…
Achieving Maximum Energy-Efficiency in Multi-Relay OFDMA Cellular Networks: A Fractional Programming Approach Abstract? The joint power and subcarrier allocation problem is solved in the context of maximizing the energy-ef?ciency (EE) of a multi-user, multi-relay orthogonal frequency division multiple access (OFDMA) cellular network, where the objective function is formulated as the ratio of the spectral-ef?ciency (SE)…
