This study proposes a state-space model with control portion for inferring Gene Regulatory Networks (GRNs). The proposed model views genes as the observation variables, whose expression values depend on the current internal state variables and control variables, and views the means of clusters of gene expression as the control variables of the internal state equation. Bayesian Information Crite...

Alkanolamine solutions such as 2-amino-2-methyl-1-propanol (AMP) are widely used in chemical industries for the removal of acid gases such as CO2 and H2S. In this work, the density of CO2, AMP, water, and AMP solutions using the Goharshadi–Morsali–Abbaspour Equation of State “GMA EoS” in the extended 50-degree range of temperatures (313.06-362.65 K) and pressures (0.5-40 MPa) was calculated. Th...

In this article, an exact analysis of compressors spool in a turbojet engine has been investigated. The spool is modeled as a rotating thick-walled hollow circular cylinder with free-clamp ends. It is subjected to centrifugal load due to its constant rotational speed, uniform internal and external radial loads and arbitrary thermal gradients. The analysis is initially investigated for the homog...

Laser-induced fluorescence excitation and dispersed fluorescence spectra of the first nlr* transition of jet-cooled 4and Smethylpyrimidine (4-mp and 5-mp) have been recorded and analyzed. In 5-mp, methyl substitution preserves many of the spectroscopic signatures of the unsubstituted pyrimidine molecule. Dispersed fluorescence spectra are used to assign most of the major features in the first 1...

Mitochondria of sperm of the sea urchin Strongylo-centrotus purpuratus are tightly coupled before induction of the acrosomal reaction. When the sperm are diluted at low external pH (pH 5.5) or in high potassium (200 mM) or in the absence of sodium, their internal pH is acidic (6.2-7.0) as measured by amine accumulation. Under these conditions the internal ATPase activity (primarily the dynein A...

This paper presents a method to verify (the internal consistency) and to validate (with respect to the purpose of the builders) Sequential Function Charts [8] (grafcets in French). The method is based upon the translation of any grafcet into its equivalent finite automaton. The proofs of consistency of the models are then established on this automaton. The main difficulty of this approach is th...

This research examines dynamics and change in the Iranian family during the recent half- century especially subsequent to the Islamic revolution in 1979. Developmental positions and changes are discussed and consideration is given to the extent to which family dynamics and change have been influenced by structural changes or ideational forces. We will focus on ideational forces based on a new a...

of local sensor data (for example, Nilsson [1980]). Reactive approaches, brandishing slogans such as “the world is its own best model,” prefer local sensor data and tend to avoid the use of internal state whenever possible (for example, Connell [1989]). Reactive approaches arose as a sort of “popular revolt” backlash against the shortcomings of traditional sense-plan-act architectures. When the...

Linear state bisection is introduced as a new method to find time-invariant state feedback control laws for a special form of underactuated nonlinear systems. The specialty of the systems considered is that every unactuated state should be coupled with at least two directly actuated states. The basic idea is based on bisecting actuated states and using linear combinations with adjustable parame...
