The main purpose of this work is the comparison of several objective functions for optimization of the vertical alignment. To this end, after formulation of optimum vertical alignment problem based on different constraints, the objective function was considered as four forms including: 1) the sum of the absolute value of variance between the vertical alignment and the existing ground; 2) the su...

background: according to clinical observations, foot hyperpronation is very prevalent and may cause malalignment of the lower extremity, leading to structural and functional deficits in standing and walking. this study aimed at investigating the effect of foot hyperpronation on spine alignment in the standing position.   methods: thirty-five healthy males with an age range of 18-30 years partic...

This work identifies the optimal sum degrees-of-freedom (DoF) of the K-user MISO Broadcast Channel (BC), in the presence of delayed channel-state information at the transmitter (CSIT) and additional current CSIT of imperfect precision. In a setting where the current channel estimation error scales — in the high SNR regime — as SNR−α for α ∈ [0, 1], the optimal sum-DoF takes the simple form (1 −...

In tele-manipulation, delays as small as a few tenths of a second can affect performance. Robot operators dissociate their control actions with what they see on delayed video and have to adopt slow move-and-wait strategies or may completely fail to perform high precision tasks. Predictive Display (PD) mitigates this problem by rendering visual feedback that reflects the operator’s motion immedi...

The final goal of strategic management is to implement strategic plans, Therefore the alignment between corporate strategy and functional strategy is considerable. This study investigates the degree of alignment between HR strategy and corporate strategy of the national gas company. Data collection was conducted by questionnaire by 51 questions. The content validity of questionnaire was assesse...

ÐThe speed of arithmetic calculations in configurable hardware is limited by carry propagation, even with the dedicated hardware found in recent FPGAs. This paper proposes and evaluates an approach called delayed addition that reduces the carrypropagation bottleneck and improves the performance of arithmetic calculations. Our approach employs the idea used in Wallace trees to store the results ...

We investigate the effect of electron-rotation coupling ($\mathbf{R}\ensuremath{-}\mathrm{\ensuremath{\Omega}}$ coupling) on fs UV photodissociation dynamics aligned diatomic molecules. consider showcase ground-state $\mathrm{Mg}{\mathrm{H}}^{+}$ (${}^{1}{\mathrm{\ensuremath{\Sigma}}}^{+}$) pumped by an IR pulse, which initiates rotational leading to field-free molecular alignment. A time-delay...

objectives: the purpose of the present study is to investigate the oral narrative skills of late talkers mostly caused by mental disorders while they try to comprehend a wordless sequential picture story to create and narrate the relevant story. methods: to this end, 15 (10 male and 5 female) participants were who were the students of a specialized school for physically and mentally retarded st...
