In [KUW1] we have proposed the setting of independence systems to study the relation between the computational complexity of search and decision problems. The universal problem that captures this relation, which we termed the $S$-search... more
We consider interval measurement logic IML, a sublogic of Zhou and Hansen's interval logic, with measurement functions which provide real-valued measurement of some aspect of system behaviour in a given time interval. We interpret IML... more
Every society that practices the division of labor and levies taxes needs to keep track of time in a predictable manner, which usually implies time-keeping based on the movements of celestial bodies. Theoretically, the sun, the fixed... more
In this paper, we introduce a simple analytical modeling approach for computing service unavailability due to long response time, for infinite and finite single-server systems as well as for multi-server systems. Closed-form equations of... more
Context. Understandability is one of the most important quality criteria in business process models (BPMs). While the experimental study of the factors that affect understandability is an ongoing research, current initiatives are focused... more

The time is very important in the life and has a special significance for hospitals, Where is specially used in operating rooms, Nurse Call System (NCS) , various medical tests and many other medical services. Those important things are... more
The Human Event Repository and Analysis (HERA) system has been developed as a tool for classifying and recording human performance data extracted from primary data sources. This paper reviews the process of extracting data from simulator... more
Behavioral, or high-level synthesis (HLS) generally produces an RTL code which in turn is synthesized into a netlist. The RTL code that is generated by the HLS pTogram needs to meet user constraints such as clock cycle, available function... more
The field of time series data mining has seen an explosion of interest in recent years. This interest has flowed over into many applications areas, including fiber manufacturing systems. The volume of time series data generated by a fiber... more
