objective: in this study, a sybr green real-time rt-pcr assay for quantification of hiv-1 viral rna was developed. materials and methods: this assay was performed based on amplification of the pol region of hiv-1 and product analysis by an abi 7500 system. we quantified hiv-1 viral load in 26 seropositive patients by this system and the data were subsequently compared with results obtained wit...

We propose a methodology to estimate a user’s interest in documents displayed on a computer screen from his or her physical actions. We introduce the ongoing pilot study’s results which showed a possible relationship between face approaches captured by a web camera and the user’s interest in the document on the screen. Some researches showed that physical actions captured through the device can...

Updating a video screen involves row replacement, i.e. the task of updating an existing screen row to produce the desired row. In many environments, screen operations require transmitting characters to the terminal by a process that is painfully slow compared to computing speeds. Thus, it is worth while to compute a minimal set of row updating commands, as long as the time to do so does not out...

Runtime enforcement is a methodology used to enforce that the output of a running system satisfies a desired property. Given a property, an enforcement monitor modifies an (untrusted) sequence of events into a sequence that complies to that property. In practice, we may have not one, but many properties to enforce. Moreover, new properties may arise as new capabilities are added to the system. ...

In crosslinguistic investigations, expressions of TIME are closely connected to SPACE (Alverson, 1994; Boroditsky, 2000, 2011; Lakoff and Johnson, 1980; Radden, 2003; Haspelmath (1997). The manifestations of TIME IS SPACE metaphor should, however, be scrutinized from a relativist viewpoint. Different cultures’ concepts of TIME may differ as a result of life experience, shared community beliefs,...

The evaluation of computer software relies on the relationship between the characteristics of the software and the efficiency of its use. To find out which characteristics of the software can influence the level of acquired knowledge, an experiment was carried out with tenth grade students in Estonian schools. Fifty-four students studied 35 units from different multimedia textbooks. Correlation...

There is considerable interest in programs that can migrate from one host to another and execute. Mobile programs are appealing because they support efficient utilization of network resources and extensibility of information servers. However, since they cross administrative domains, they have the ability to access and possibly misuse a host’s protected resources. In this paper, we present a nov...

It is becoming increasingly common to see computers with two or even three monitors being used today. People seem to like having more display space available, and intuition tells us that the added space should be beneficial to work. Little research has been done to examine the effects and potential utility of multiple monitors for work on everyday tasks with common applications, however. We com...
