The technological advancement in drones, unmanned aerial vehicles (UAV), wind turbines, and airfoil research has grown rapidly since last decade. Computational fluid dynamics (CFD) analysis is commonly used to study the airflow around a body. Yet, tunnel an essential instrument aerodynamic research; however, commercial normally comes with small test section incurs high investment costs. This pa...

in this paper, distributed parameter process systems behavior is studied in frequency domain. based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. by using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

By taking the high-energy limit of the two-loop and the three-loop four-point amplitudes in the maximally supersymmetric N = 4 Yang-Mill theory (MSYM), we test the validity of the loop expansion of the high-energy amplitude, beyond the next-to-leadinglogarithmic (NLL) accuracy. We compute the three-loop Regge trajectory, and the two-loop and three-loop coefficient functions. These quantities ar...

Background The anterior loop is an important structure in the interforaminal area of the mandible. The aim of the present study was to assess the prevalence and length of the anterior loop of mental nerve using cone beam computed tomography (CBCT) scan and to compare the differences between age, gender, and side. Materials and Methods A total of 180 projections were analyzed in different sect...

A legislative change in takeoff and landing restrictions at LaGuardia Airport provides an opportunity to study the effect of an exogenous shock to product quality on prices in the airline industry. I test how the price response varies with the degree of competition in the market. I find that prices fall by $1.42 on average for each additional minute of flight delay, and that the price response ...

The traditional theory of Laplace transformation (TLT) as it was put forward by Gustav Doetsch was principally intended to provide an operator calculus for ordinary derivable functions of the t-domain. As TLT does not account for the behavior of the inverse L-transform at t = 0 its validity is essentially confined to t > 0. However, from solutions of linear differential equations (DEs) one can ...

Automated identification of tasks in email messages can be very useful to busy email users. What constitutes a task varies across individuals and must be learned for each user. However, training data for this purpose tends to be scarce. This paper addresses the lack of training data using domain-specific semantic features in document representation for reducing vocabulary mismatches and enhanci...
