maraghe observatory was built by such engineers as moayiededdin orozi etc. under supervision of khaje nasireddin tousi in 7th century ah. the most significant feature associated with maraghe observatory is the fact that architecture is employed to achieve astronomical purposes in this site. the reason for preferring observatory by astronomers was the fact that these units are superior to wooden...

The purpose of this study was to evaluate the performance of a commercially avail-able CyberKnife system with a multileaf collimator (CK-MLC) for stereotactic body radiotherapy (SBRT) and standard fractionated intensity-modulated radiotherapy (IMRT) applications. Ten prostate and ten intracranial cases were planned for the CK-MLC. Half of these cases were compared with clinically approved SBRT ...

We identify a new class of non-circular attribute grammars, called the multi-plan attribute grammars, for which static evaluation plans can be computed. The class of multi-plan attribute grammars is larger than all currently known classes of non-circular attribute grammars with static evaluation plans. The decision procedure and the procedure for computing evaluation plans take essentially poly...

Multileaf collimator (MLC) technology has been newly introduced with the Cyberknife system. This study investigated the advantages of this system compared with the conventional circular collimator (CC) system. Dosimetric comparisons of MLC and CC plans were carried out. First, to investigate suitable target sizes for the MLC mode, MLC and CC plans were generated using computed tomography (CT) i...

A new movement in urban environmental policy, the circular economy (CE), aims to change how Europeans consume and produce materials energy. Cities are taking up CE challenge. This research inquires whether infant programs European cities include cultural heritage adaptive reuse of (ARCH) buildings. ARCH buildings exemplify central principal CE, which is a temporally long service life with multi...

The greater part of the reversible data hiding approaches proposed so far fuse a lossless information compression stage. The utilization of an elaborate data compression stage increases the complexity of watermarking. There are some watermarking plans that don't depend on extra data compression, with respect to example, circular histogram interpretation schemes. In this paper a survey is presen...

Curtis-Ingerman-Morrow studied the space of circular planar electrical networks, and classified all possible response matrices for such networks. Lam and Pylyavskyy found a Lie group EL2n whose positive part (EL2n)≥0 naturally acts on the circular planar electrical network via some combinatorial description, where the action is inspired by the star-triangle transformation of the electrical netw...

Propositional plans of all forms often display a certain level of concurrency which can be exploited by scheduling the plan. This reveals the earliest times at which each action can be applied whilst still achieving the goal and shortening the plan duration. However, the output of this scheduling process is simply a set of timestamped actions, losing implicit information present in the original...

literature review indicates that systemic agricultural human resource development (hrd) interventions are rarely carried out in developing countries, and limited knowledge exists about how successful they have been. a comparative study was carried out to investigate the effectiveness of three multi-project hrd interventions including extension plans, adaptation plans and diffusion-push plans in...
