This work reviews the effect of parametric programming on visual performance, daylighting and shading in office buildings in Tehran-Iran and studies their influences that help not only to reduce the glare but also to promote useful daylight illuminance through promoting visual comfort. It starts by establishing a review of the effective parameters on visual comfort indices, glare indices, and d...

Abstract Studying the physical and chemical conditions of young embedded disks is crucial to constrain initial for planet formation. Here we present Atacama Large Millimeter/submillimeter Array observations dust continuum at ∼0.″06 (8 au) resolution molecular line emission ∼0.″17 (24 toward Class 0 protostar L1527 IRS from Program eDisk (Early Planet Formation in Embedded Disks). The smooth wit...

Performance characteristic of an Unmanned Air Vehicle (UAV) is investigated using a newly developed heuristic approach. Almost all flight phases of any air vehicle can be categorized into trim and maneuvering flights. In this paper, a new envelope called trim-ability envelope, is introduced and sketched within the conventional flight envelope for a small UAV. Optimal maneuverability of the inte...

due to the important role of subsurface drainage in managing the ground water level, there are many researches focused on finding a new and more economic way to develop subsurface drainage technologies. lack of proper drainage system in northern iran has caused huge implantation of rice and it is impossible to have second implantation in this region. one reason of insufficiency of current drain...

We present maps of the 12 CO(3–2) and C 18 O(2–1) emission around T Tauri. By comparison of the two lines measured with similar spatial resolution we are able to discriminate between the different components of molecular circumstellar material and to derive constraints for possible source models. In particular we are able to trace the outflowing molecular components. We propose a multiple outfl...

Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...

The surface of lo may be covered with a layer of ammonia ice containing trace amounts of sodium potassium, and calcium; and atmospheric nitrogen could be formed as a photochemical product of ammonia photolysis. Intense sporadic sodium emission from Io can be excited by collisions involving vib~ationally excited n.itrogen molecules. These metastable molecules may be formed by electron impact, wi...

High resolution ( 4") aperture synthesis maps of the CO (1 .... 0), 13CO (1 .... 0), 13CO ( 2 .... 1), and associated continuum emission from the FU Orionis candidate V1331 Cygni reveal a massive, 0.5±0.1510 , circumstellar disk surrounded by a flattened gaseous envelope, 6000X4400 AU in size, mass ;;.0.3210 . These images and lower resolution measurements also trace a bipolar outflow and gaseo...

We propose a simple but powerful scheme for the complete analysis of the frequency chirp of a gain-switched optical pulse using a fringe-resolved interferometric two-photon absorption autocorrelator. A frequency chirp imposed on the gain-switched pulse from a laser diode was retrieved from both the intensity autocorrelation trace and the envelope of the second-harmonic interference fringe patte...
