Aims: In the rapidly advancing world of laparoendoscopic surgery, surgeons are faced with new devices all of which are aimed towards a single access. Various single-access devices are available on the market. Our study aimed to compare the performance of experienced laparoscopic surgeons on validated laparoscopic tasks using five devices within a simulation setting. Methods: Ten experienced con...

We had introduced the massively parallel global cellular automata (GCA) model. Parallel algorithms derived from applications can be mapped straight forward onto this model. In this model a cell in the cell field is dynamically connected (access pattern, dynamic neighbourhood) to other cells. The model can be implemented by pointers stored in the cell state. Via these pointers, each cell has rea...

web is a great source of information and knowledge, where a numerous of users find their interest. The data available is in form of structured (relational) and text data. Therefore, different kinds of data model can be implementable with web data for pattern discovery. Web mining is a data mining tool where the web related data is evaluated for pattern discovery and user navigation pattern. Add...

The problem of fast address lookup is crucial to routing and thus has received considerable attention. Most of the work in this field has focused on improving the speed of individual accesses – independent from the underlying access pattern. Recently, Gupta et al. [7] proposed an efficient data structure to exploit the bias in access pattern. This technique achieves faster lookups for more freq...

Web access logs, usually stored in relational databases, are commonly used for various data mining and data analysis tasks. The tasks typically consist in searching the web access logs for event sequences that support a given sequential pattern. For large data volumes, this type of searching is extremely time consuming and is not well optimized by traditional indexing techniques. In this paper ...

Data broadcasting is an effective approach to disseminate public information to mobile clients in wireless mobile environments. In some applications, the access pattern of all the data can be represented by a weighted DAG. In this paper, we explore how the server generates the broadcast schedule, for the data set having a DAG access pattern, which not only minimizes the access latency but also ...

The testability problem of dual port memories is investigated. Architectural modifications to enhance the testability by allowing multiple access of memory cells with minimal overhead on both silicon area and device performance are described. New fault models are proposed and efficient O( n ) test algorithms are described for both the memory array and the address decoders. The new fault models ...
