Risk ranking of Horizontal Directional Drilling (HDD) for gas and oil wells is a key criterion in the project feasibility, pricing and for introducing a risk management strategy that aims to reduce the number of failures in the installation phase and its negative consequences. HDD is currently widely used in drilling wells in Iran, but research in the area of identification and risks ranking of...

When major emergencies or accidents occur, risk evaluation and prediction are the most important means to reduce their impact. Typical uses failure mode effects analysis (FMEA) method for failure-risk ranking control. However, when faced with severe special infectious diseases such as COVID-19, there many cognitive information uncertainties that FMEA is unable effectively handle. To deal issue ...

recent advances in wireless and mobile communications infrastructure are enabling governments to deliver and manage services to citizen efficiently and economically. mobile government provides this ability to governments. this paper presents the ggovernance approach in effective development of mobile government. the objective is reviews(identify and ranking) of public service concept (included:...

Fuzzy risk analysis, as a powerful tool to address uncertain information, can provide an appropriate method for risk analysis. However, the previous fuzzy risk analysis methods still have some weaknesses. To overcome the weaknesses of existing fuzzy risk analysis methods, a novel method for ranking generalized fuzzy numbers is proposed for addressing fuzzy risk analysis problems. In the propose...

With today’s keen competition, semiconductor market has changed from producer-oriented to customer-oriented. To be successful, companies need to consider both customer satisfaction in demand and the ultimate profit goal of companies. Semiconductor fabricators today must face an environment with multi-product types and multi-priority orders. Since semiconductor fabrication has a very complicated...

OBJECTIVES To identify priority policy issues in access to medicines (ATM) relevant for low- and middle-income countries, to identify research questions that would help address these policy issues, and to prioritize these research questions in a health policy and systems research (HPSR) agenda. METHODS The study involved i) country- and regional-level priority-setting exercises performed in 1...

There are various methods applied for indicating the most sensitive bus for any corrective and preventive actions like power scheduling at generation site and shunt element placement such as capacitor bank and FACTS devices at load site. The methods can be sensitivity analysis, optimization method, stability index based ranking and lastly the method that is rarely applied, termed as power traci...

We present a new context based event indexing and event ranking model for News Articles. The context event clusters formed from the UNL Graphs uses the modified scoring scheme for segmenting events which is followed by clustering of events. From the context clusters obtained three models are developed-Identification of Main and Sub events; Event Indexing and Event Ranking. Based on the properti...

Female dominance and feeding priority are considered unique behavioral strategies in many Malagasy lemuriformes, particularly Lemur catta. Two hypotheses have been introduced to explain these behavior patterns: 1) females are agonistically dominant over males to mitigate female-male food competition so that females can compensate for high energy demands and inefficient reproductive physiology, ...
