Background: Human Adenovirus species D (HAdV-D) was common human viral pathogen especially in eye infection, consists of several types of which HAdV-D8, -D19 and –D37 were common in eye infection. This study includes detection of HAdV-D types implicated in conjunctivitis based on L2 (Penton protein) gene similarity. Methods: Conjunctival swabs were collected from Keratoconjunctivitis patient...

Engineering applications that use Active DBMSs (ADBMSs) often need to group activities into modes that are shifted during the execution of different tasks. This paper presents a mechanism for grouping rules into contexts that can be activated and deactivated dynamically. The ADBMS monitors only those events that affect rules of activated contexts. By dynamic rule grouping the rules to be monito...

It has been believed that a statistical multiplexing technique can bring an effective bandwidth usage. When it is applied to MPEG-2 video, it has been pointed out that two to several times multiplexing gain can be attained due to highly bursty nature of video traffic. However, most of past researches do not take into account the implementation aspects of this technique. In this paper, we thorou...

The Available-Bit-Rate (ABR) service that is being standardized b y the A T M Forum dynamically determines the maximum transmission rate, so-called ezplicit rate, of a connection. A drawback of the A B R control scheme for calculating the explicit rates is that it tries to allocate the.same bandwidth t o a l l A B R connections regardless of the application t y p e of the connection. In this st...

The Available-Bit-Rate (ABR) service that is being standardized by the ATM Forum dynamically determines the maximum transmission rate, the explicit rate, of a connection. A drawback of the dynamic control scheme for calculating the explicit rates is that it tries to allocate the same bandwidth to all ABR connections regardless of the application type of the connection. In this study a multi-lev...
