to effectively design daylight in buildings, daylight availability data are necessary. although there is a great potential for daylight energy in iran, its use has been hampered by the absence of measured data. in this paper the illuminance data on the vertical south facing surfaces of tehran were estimated using the iesna model. for this propose an illuminance measuring set was used in order t...

This paper discusses a measurement-based approach to dependability evaluation of fault-tolerant, real-time software systems based on failure data collected from stability tests of an air traffic control system under development. Several dependability analysis techniques are illustrated with the data: parameter estimation, availability modeling of software from the task level, applications of th...

the impact of the international sanctions on the central bank of iran in 2013 and also accessibility of medicines in this country have received a lot of media coverage. in this study we used the data collected from a group of pharmacies all located in tehran to assess the potential effects of the banking sanctions on access to asthma medicines. data were collected from forty community pharmacie...

The emerging field of self-repair computing could have a major impact on deployable systems for space missions and defense applications. These systems must survive and perform at optimal functionality for long durations in unknown, harsh, and/or changing environments. Examples of such applications include outer solar system exploration, missions to comets and planets with severe environmental c...

This paper presents a decision making approach for mid-term scheduling of large industrial consumers based on the recently introduced class of Stochastic Dominance (SD)- constrained stochastic programming. In this study, the electricity price in the pool as well as the rate of availability (unavailability) of the generating unit (forced outage rate) is considered as uncertain parameters. Th...

Two reliability models for a system of non-identical units – one is original and the other is a substandard unit (called duplicate unit) are analyzed probabilistically in detail by using regenerative point technique. There is a single server who comes immediately to do inspection and repair whenever needed. On the failure of original unit, server inspects the operative duplicate unit to see whe...

In this paper, an exact geometric algorithm is presented for solving two-job sequencing and scheduling problems in flexible flow shop and job shop environments while the resources are (un)available in some time periods and processors (un)availability is the same in all work centers. This study seems utterly new and it is applicable to any performance measure based on the completion time. The in...

Finding an empty parking lot is a big challenge as it can take lots of time and resources. This paper describes the design development prototype smart system for assisting vehicle drivers who always experiencing problem in finding indoor lots. The objectives proposed are to develop IoT utilizing ultrasonic sensor detect presence mobile application display layout car locate lot.For controller un...

The speech-to-speech translation system is becoming an important research topic with the progress of the speech and language processing technology. Considering efficiency and the smoothness of the cross-lingual conversation, the simultaneity of the translation processing has a great influence on the performance of the system. This paper describes interpreting unit segmentation of conversational...
